Description
FIELD OF THE INVENTION
[0001] The invention relates to a drilling apparatus arrangement
with a drilling apparatus which has a crawler running gear, on
which a drill mast with a drill drive is supported that is designed
for driving a drill rod and supported in an axially movable manner
along the drill mast, wherein the drill mast is adjustable via a
multi-joint arm into a plurality of drilling positions in space,
and with an operator's cab for at least one operating person for
controlling the drilling apparatus.
[0002] The invention further relates to a method for producing a
bore, in particular an injection anchor bore, in particular with
such a drilling apparatus arrangement, in which a drill rod with a
drill head is driven in a rotating manner by a drill drive which,
for the purpose of introducing the bore into a ground or wall area,
is moved axially along a drill mast that is adjustable by means of
a multi-joint arm of a drilling apparatus into a plurality of
drilling positions in space, wherein a drilling operation is
controlled by at least one operating person from an operator's
cab.
BACKGROUND OF THE INVENTION
[0003] Drilling apparatuses of such type are also referred to as
anchor drilling rigs. Due to the fact that anchors are introduced
not only vertically into the ground but in many cases in a
plurality of different angles into wall and ceiling areas, e.g. to
support excavation pit walls or for slope or tunnel rehabilitation,
a drill mast is freely adjustable via a multi-joint arm with
respect to a basic apparatus into a plurality of drilling positions
in space. Such a drilling apparatus can be taken from DE 20 2014
000 508 U1 for example.
[0004] An upper carriage on such a drilling apparatus is of very
compact design so as not to hinder and restrict, as far as
possible, the plurality of adjustment options of the drill mast in
space. Usually, the operator's cab is located in a rear area of the
drilling apparatus, in which case the operator's cab is often
designed as a simple operating platform.
[0005] In many cases the drill mast conceals the view from the
operating platform onto the working area near the drilling starting
point. Hence, for a positionally precise introduction of bores by
means of the drill mast that is freely adjustable in space it is
often necessary for the operating person to leave the operating
platform and take a position close to the working area, thereby
allowing the operating person to have a good view onto the working
area with the drilling starting point. In these cases, control of
the drilling apparatus is effected via a portable operating panel
that the operating person carries with him. The operating panel is
relatively heavy and, despite the use of carrying straps, proves to
be a physical strain in the long run.
[0006] Moreover, this arrangement has the drawback that the
operating person is without protection in the open air. The
operating person is thus exposed to the influence of weather on the
construction site. In bad weather conditions this can affect the
drilling operation or even bring it to a standstill. In addition,
the positioning of the unprotected operator directly at the
drilling point is also disadvantageous from the point of view of
safety at work.
[0007] In an internet article by Mattias Hjierpe dated 22 Dec. 2015
the use of a remote control with a video camera system is taught to
increase the safety of an operating person during drilling in a
hazardous area. The remote control station can be arranged at a
safe distance to the drilling location in a container or a
vehicle.
SUMMARY OF THE INVENTION
[0008] The invention is based on the object to provide a drilling
apparatus arrangement and a method for producing a bore, with which
on the one hand efficient drilling and on the other hand good
operability for the operating person are given.
[0009] The object is achieved on the one hand by a drilling
apparatus arrangement having the features of claim 1 and on the
other hand by a method for producing a bore having the features of
claim 10.
[0010] Preferred embodiments of the invention are stated in the
respective dependent claims.
[0011] In the case of the drilling apparatus arrangement according
to the invention provision is made for the operator's cab to be
designed as a mobile operating unit that is arranged separately
from the drilling apparatus on an independent running gear.
[0012] A basic idea of the invention can be seen in the fact that
the drilling apparatus is of two-part construction and that the
operator's cab is designed as a mobile operating unit. In
accordance with the invention the mobile operating unit is provided
with an independent running gear so that the operating person can
move with the mobile operating unit. Due to the separate and mobile
design of the operating unit with an independent running gear this
can be moved independently of the drilling apparatus. This allows
the operating unit to always be arranged in such a way that it does
not impede the adjustability of the drill mast in space in the
specific situation on the construction site. At the same time, the
operating unit can be moved in such a way via the independent
running gear by the operating person that a good view of the
drilling starting point can be reached at all times.
[0013] Basically, the operator's cab can be connected to the
drilling apparatus in any chosen way, in particular in a
cable-bound manner. According to an embodiment of the invention it
is especially preferred that the operator's cab has an operating
panel that is wirelessly connected to a control means of the
drilling apparatus. In this way, a high degree of independence and
freedom of movement is achieved between the drilling apparatus on
the one hand and the operator's cab on the other hand. For specific
purposes a stationary operating platform, preferably being of
simplified design, can furthermore be provided on the drilling
apparatus. In particular, the cable-free connection is a radio
signal connection.
[0014] Basically, the mobile operating unit can be provided for a
single person only. According to an embodiment of the invention it
is preferred that the operator's cab is designed for receiving at
least two persons. The two persons can assume different functions.
Thus, a driver for moving the mobile operating unit and the actual
operating person for the drilling apparatus can be arranged in a
protected manner.
[0015] Basically, the mobile operating unit can also be provided
for controlling several drilling apparatuses so that an efficient
deployment of staff is rendered possible.
[0016] Basically, the operator's cab of the mobile operating unit
can be designed as an open operating platform. According to a
further development of the invention it is particularly
advantageous for the operator's cab to be of closed design. In
particular, the operator's cab can be provided with windows and
doors and preferably with protective grids as well as air
conditioning. As a result, especially good work protection as well
as protection against the influence of weather is achieved.
[0017] Especially good mobility is accomplished in that the running
gear of the mobile operating unit is designed as a crawler running
gear or a wheel running gear. The running gear can be designed
similar to the running gear of so-called mini excavators that are
also offered as crawler- or wheel-type vehicles. These can be
obtained at a reasonable price and offer high maneuverability even
in rough terrain. Basically, the mobile operating unit can be of
such compact design that it can be releasably coupled with the
actual drilling apparatus. In this way, the drilling apparatus can
also be moved with the mobile operating unit as one unit.
[0018] According to a further development of the invention another
improvement of the operability of the drilling apparatus and the
applicability of the mobile operating unit is achieved in that the
running gear is designed as an undercarriage and in that on the
undercarriage an upper carriage with the operator's cab is
supported in a rotatable manner. All in all, a very good overview
by the operating person in the mobile operating unit even onto
several drilling apparatuses or onto the construction site as a
whole can thereby be realized.
[0019] In accordance with the invention the drilling apparatus
arrangement is characterized in that the mobile operating unit is
provided with a drive means that is designed for driving at least
one working means. Hence, apart from having a mere operating and
control function the mobile operating unit can also be used as an
additional working apparatus for specific tasks.
[0020] It is especially advantageous for the working means to have
a lifting gear, a gripping means, a support arm and/or a rope
winch. According to the invention the mobile operating unit is
provided with a gripping means on a movable support arm so that
handling operations of drill rod elements can also be carried out
with the mobile operating unit. For instance, new drill rod
elements can be supplied to the drill mast or, during dismantling
of the drill rod, drill rod elements can be removed and transported
to a magazine.
[0021] With regard to the method the invention is characterized in
that the operator's cab is designed as a mobile operating unit
which is moved separately from the drilling apparatus by means of
an independent running gear. The method can be carried out in
particular by way of the previously described drilling apparatus
arrangement according to the invention. The advantages described
beforehand can be achieved thereby.
[0022] Basically, the produced bore can be used for various
purposes, e.g. for blast hole bores, geothermal bores, exploratory
bores or for other purposes. According to a further development of
the invention it is particularly advantageous that as drill rod
with the drill head a tension member is provided which remains in
the bore and is anchored therein after production of the bore. In
particular, an injection anchor can be provided which, after
production of the bore, is firmly anchored in the ground or rock
material by injecting or filling in a hardenable suspension.
[0023] According to an embodiment variant of the method pursuant to
the invention a particularly high flexibility in producing the bore
is achieved in that the drilling apparatus is controlled wirelessly
from the mobile operating unit by the operating person. For safety
reasons the control can be designed such that the operation of the
drilling apparatus is stopped when a connection of the drilling
apparatus to the mobile operating unit is interrupted.
[0024] According to a further embodiment variant of the invention
it is advantageous that the mobile operating unit is provided with
a support arm and a gripping means, by which drill rod elements are
gripped and supplied to the drilling apparatus or removed
therefrom. Preferably, the gripping means is designed as a pipe or
drill rod gripper with at least two clamping claws. The gripping
means is mounted at the free end of the excavator arm. The
excavator arm can be designed as a multi-joint arm.
BRIEF DESCRIPTION OF THE DRAWINGS
[0025] In the following the invention is described further by way
of embodiments illustrated schematically in the accompanying
drawings, wherein show:
[0026] FIG. 1 a schematic side view of a drilling apparatus
arrangement and
[0027] FIG. 2 a schematic side view of a drilling apparatus
arrangement according to the invention.
DESCRIPTION OF PREFERRED EMBODIMENTS
[0028] A drilling apparatus arrangement 10 according to FIG. 1 has
a drilling apparatus 20 which is designed in the illustrated
embodiment for drilling down a drill rod 40 for an injection
anchor. The drilling apparatus 20 comprises a carrier unit 24 with
the drive units, wherein the carrier unit 24 is movable by means of
a crawler running gear 22. In a front area of the drilling
apparatus 20 a multi-joint arm 26 with a drill mast 30 is
supported. By way of the multi-joint arm 26 the drill mast 30 can
be adjusted into a plurality of drilling positions with various
vertical and horizontal alignments in space.
[0029] This allows the introduction of bores at almost any angle
into ground or into wall and ceiling areas.
[0030] The drill mast 30 is provided with a linear guide 32, along
which a drill drive 34 is supported in a linearly movable manner.
The drill drive 34 can be of any chosen design, e.g. as a rotary
drive for single- or double-head drilling or for percussion
drilling. By preference, the drill drive is designed for driving
the drill rod 40 in a rotating manner. The drill drive can also be
designed as a percussion or vibration drive so that the drill rod
40 can be advanced without rotational movement or in addition
thereto. The drill rod 40 is preferably composed of individual
drill rod elements 42 that are stored near the drilling
location.
[0031] On the borehole-facing end of the drill rod 40 a drill head
with a cutting means is arranged that is not depicted in FIG. 1. On
the front end of the drill mast 30 a clamping and breaking means 36
is mounted, with which the drill rod 40 can be screwed together of
the drill rod elements 42 or released again in a known manner.
[0032] To control the drilling apparatus 20 a mobile operating unit
50 with an operator's cab 52 for at least one operating person is
provided. The mobile operating unit 50 has an independent running
gear 54, allowing the mobile operating unit 50 to be moved
independently with respect to the drilling apparatus 20.
[0033] In the illustrated embodiment according to FIG. 1 the
running gear 54 of the mobile operating unit 50 is designed as an
undercarriage 56 with a wheel running gear. On the undercarriage 56
an upper carriage 58 with the operator's cab 52 is supported in a
rotatable manner. On the upper carriage 58 a drive, preferably a
combustion engine or an electric motor, is arranged so that the
mobile operating unit 50 can be moved independently. The operator's
cab 52 is designed as a closed housing with windows and doors so
that the operating person is protected against weather or
environmental influences.
[0034] The mobile operating unit 50 renders it possible for an
operating person to move separately from the drilling apparatus 20
into a chosen and suitable position in the working area of the
drilling apparatus 20. In particular, it is preferred that the
operating person has an unobstructed view of the working area with
the drilling starting point.
[0035] Control of the drilling apparatus is effected by the
operating person from the mobile operating unit 50 with a
corresponding control, in particular an operating panel. The
control or the operating panel are preferably connected via a
wireless or cable-free connection to the control on the drilling
apparatus 20. In addition, an operating platform 28 can be arranged
on the drilling apparatus 20. This creates the possibility for the
drilling apparatus 20 to also be operated without the mobile
operating unit 50 but directly via the operating platform 28. The
operating platform 28 is designed as a simple and preferably open
operating platform 28 that is in particular suitable for moving the
drilling apparatus 20 when the drill mast 30 is retracted.
[0036] A drilling apparatus arrangement 10 according to the
invention is shown in FIG. 2. The drilling apparatus 20 is designed
corresponding to the drilling apparatus 20 according to FIG. 1. In
the illustration according to FIG. 2 the multi-joint arm 26 that
has at least three joints, by preference up to eight or more
joints, is arranged such that the drill mast 30 with the drill
drive 34 is located in a vertical drilling position.
[0037] In the drilling apparatus arrangement 10 according to FIG. 2
a mobile operating unit 50 with the operator's cab 52 is provided,
with a running gear 54 of an undercarriage 56 being designed as a
crawler running gear. On the undercarriage 56 an upper carriage 58
with the operator's cab 52 is supported in a rotatable manner. On
the upper carriage 58 a support arm 62 with a gripping means 64 is
arranged as a working means 60. The support arm 62 which can also
be referred to as excavator arm is adjustable in space via several
joints and drive members. The gripping means 64 is designed to grip
individual drill rod elements 42 from a drill rod element magazine
and supply these to the drill mast 30 to form the drill rod 40.
[0038] Conversely, the working means 60 can also be used for
dismantling a drill rod 40 and for returning the individual drill
rod elements 42 from the drill mast 30 back to the drill rod
element magazine. The working means 60 is supplied with energy by a
drive means 66 arranged on the upper carriage 58. The drive means
66 preferably has a combustion engine that drives a hydraulic unit
for supplying hydraulic energy to the working means 60.
[0039] With this additional working means 60 the mobile operating
unit 50, which is provided and designed for controlling the
drilling apparatus 20, can carry out an additional function at the
same time. This enables an operating person of the drilling
apparatus 20 to also execute additional functions in an efficient
manner. Hence, the required expenditure of staff on a construction
site can be reduced. If necessary, the operator's cab 52 of the
mobile operating unit 50 can also be provided for receiving two or
more operating persons.
