Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to German Patent
Application No. 10 2011 109 080.4, entitled "Revolving Deck Element
for a Construction Machine," filed Jul. 27, 2011, which is hereby
incorporated by reference in its entirety for all purposes.
TECHNICAL FIELD
[0002] The present disclosure relates to a revolving deck element
for a construction machine, in particular for a mobile excavator,
as well as to a construction machine, in particular to a mobile
excavator.
BACKGROUND AND SUMMARY
[0003] With construction machines which have an undercarriage which
bears a chassis and which have a superstructure pivotally connected
to the undercarriage, it is customary that the construction
machines differ in the manner of the traveling gear used. It is in
particular possible that the undercarriage carries a traveling gear
which can be designed, for example, as a simple wheel traveling
gear or also as a tracked traveling gear. The superstructure of the
construction machine is pivotally connected, for example rotatably,
to this undercarriage carrying the traveling gear.
[0004] The superstructure in this respect substantially comprises a
revolving deck on whose upper side and on the side walls disposed
to the side in the direction of travel, in particular the side wall
disposed at the right, possibly all modules of the superstructure
are arranged at standardized interfaces.
[0005] It is currently known from the prior art how to manufacture
the revolving decks as an individual job, depending on the
construction machine type. In this respect, the assembly of the
revolving deck takes place at a separate fixed workplace, depending
on the construction machine type. A further disadvantage is that an
optimization of the clippings of the material required for the
revolving deck is not possible over different units.
[0006] It is therefore the object of the present disclosure to
further develop a revolving deck of the initially named kind in an
advantageous manner, in particular such that a revolving deck for a
construction machine can be manufactured less expensively and more
flexibly.
[0007] This object is satisfied in accordance with the present
disclosure by a revolving deck for a construction machine where
provision is accordingly made that a revolving deck element has a
base body, wherein the base body substantially comprises a base
plate and two main webs aligned to the longitudinal vehicle axis,
wherein the main webs are arranged on the base plate and are fixed
at a position defined by the work equipment width and the operator
workplace width by transverse webs.
[0008] The construction machine can in particular be a mobile
excavator.
[0009] It becomes possible by this design of a revolving deck
element to be able to provide a predefined structure for a
revolving deck element for a construction machine which can be used
across production series. A simple and simultaneously stable
structure is possible by the design by a base body, main webs and
transverse webs. The revolving deck element can in particular
always be made the same, in particular in a plurality of production
series, for example in all production series of a construction
machine type, in particular with mobile excavators. The advantage
hereby results that a revolving deck for a construction machine can
be manufactured and treated less expensively in production and
assembly. A greater flexibility in production logistics furthermore
results.
[0010] Provision can furthermore be made that the revolving deck
element is of modular design and/or is designed as a standard
component.
[0011] It is possible that the revolving deck element has at least
one interface by which the revolving deck element can be connected
to at least one optionally selectable side part module of the
construction machine. Such optionally selectable side modules can,
for example, be the side part module construction or the side part
module LH on which in particular hydraulic elevated portions and
tilt apparatus can be mounted.
[0012] It is further conceivable that the main webs are arranged
substantially perpendicular to the base plate.
[0013] Provision can furthermore be made that the revolving deck
element has at least one interface by which the revolving deck
element can be connected to at least one component of the
superstructure of the construction machine. In this respect, it can
be a standardized interface.
[0014] Provision is further made that the component of the
superstructure is and/or includes an operator workplace, a
hydraulic tank, a fuel tank, a climbing box, a drive module, a
ballast weight and/or a control slide valve console.
[0015] It is furthermore conceivable that the base plate, the main
webs and/or the transverse webs are at least partly releasably
connected to one another, in particular releasably screwed or
releasably bolted.
[0016] It is furthermore possible that the base plate, the main
webs and/or the transverse webs are at least partly non-releasably
connected to one another, in particular welded to one another.
[0017] It is moreover possible that the base body has an at least
partly cage-like and/or at least partly box-like structure, with
the bounding elements of the structure in particular being the base
plate, the main webs and/or the cross-webs.
[0018] Provision can furthermore be made that the main webs are
formed at least partly trapezoidally.
[0019] The present disclosure furthermore relates to a construction
machine. Provision is accordingly made that a construction machine,
in particular a mobile excavator, has at least one revolving deck
element as described above and below herein.
[0020] Further details and advantages of the present disclosure
will now be explained with reference to an embodiment shown in the
drawing.
BRIEF DESCRIPTION OF THE FIGURES
[0021] FIG. 1 shows a perspective exploded view of a superstructure
of a construction machine.
[0022] FIG. 2 shows a further perspective view of the
superstructure of a construction machine.
[0023] FIG. 3 shows a plan view of a revolving deck in accordance
with the present disclosure.
[0024] FIG. 4 shows a perspective exploded view of the revolving
deck and of the further modules of the construction machine to be

although other relative dimensions may be used, if desired.
DETAILED DESCRIPTION
[0025] FIG. 1 shows, in a perspective exploded view, the modules of
a superstructure of a construction machine, here a mobile
excavator.
[0026] The superstructure of the mobile excavator in this respect
itself substantially comprises a revolving deck 10 on whose upper
side and on whose side wall disposed at the right in the direction
of travel all modules of the superstructure are arranged at
standardized interfaces. The modules of the superstructure comprise
the revolving deck 10 on which the operator workplace 20 is
arranged. The operator workplace 20 in a mobile excavator
substantially comprises an operator's cabin 21 and a control unit
22. In a construction machine designed as a transfer unit, this
operator workplace 20 is optionally supplemented by rigid elevated
portions 23, hydraulic elevated portions 24 and tilting apparatus
25.
[0027] The hydraulic tank 30, the fuel tank 40 and the climbing box
50 are likewise fastened to the upper side or to the side wall of
the revolving deck 10 disposed at the right in the direction of
travel. In this respect, the fuel tank 40 can be designed in
different embodiments with respect to the fuel volumes. The drive
module 60 is likewise fastened to the upper side or to the side
wall of the revolving deck 10 disposed at the right in the
direction of travel.
[0028] The drive module 60 can include either one of an internal
combustion engine, an electric motor or a fuel cell with batteries.
It is also conceivable that both an internal combustion engine and
an electric motor and/or a fuel cell with batteries are provided as
a hybrid concept.
[0029] The ballast weight 70 is likewise attached to the upper side
of the revolving deck 10.
[0030] The ballast weights can now be replaced across different
types of units due to the harmonization of the superstructure width
and height and the payload behavior of the machine can thus be
varied very easily.
[0031] A control slide valve console 80 is furthermore provided
which includes the total valve arrangement. The control slide valve
console 80 is likewise fastened to the upper side or to the side
wall of the revolving deck 10 disposed at the right in the
direction of travel.
[0032] FIG. 2 shows the aforesaid components of the superstructure
of the construction machine in a further perspective view.
[0033] FIG. 3 furthermore shows a plan view of the revolving deck
10 from which the arrangement of the operator workplace 20, the
hydraulic tank 30, the fuel tank 40, the climbing box 50, the drive
module 60, the ballast weight 70 and the control slide valve
console 80 can be seen.
[0034] As can further be seen in detail from FIG. 4, the revolving
deck is designed as a central module which is reduced as much as
possible to a compact base body 100. This compact base body 100
essentially comprises a base plate 101 and two main webs 102
aligned in the longitudinal axis of the vehicle. These main webs
102 are perpendicular to the base plate 101 and are fixed at a
position defined by the work equipment width and operator workplace
width by transverse webs 103. This central module 100 or the base
body 100 has defined interfaces to the optionally selectable side
modules, with such side modules being able to be the side part
module construction 120 or the side part module LH 130 on which
hydraulic elevated portions 24 and tilting apparatus 25 are
mounted.
[0035] The base body 100 has an at least partly cage-like and at
least partly box-like structure and shape, wherein the bounding
elements of the structure are the base plate 101, the main webs 102
and the transverse webs 103. Provision is furthermore made that the
main webs 102 are formed at least partly trapezoidally. In this
respect, pivotal connection points for further components of the
superstructure are in particular provided in the upper region and
at the front part of the main webs 102.
[0036] The interfaces of the superstructure components, for
example, the main superstructure components operator workplace 20,
hydraulic tank 30, fuel tank 40, climbing box 50, drive module 60,
ballast weight 70 and control slide valve console 80, are
standardized so that these main superstructure components can be
connected without problem to the revolving deck 10 across
production series. The advantage hereby results of being able to
use the revolving deck 10 across production series for a plurality
of production series of a construction machine, whereby a reduction
of the production and assembly costs results.
[0037] It is therefore now possible to be able to produce the
individual modules required in connection with a revolving deck 10
independently of the job. Production can thus be carried out on
demand, for example, on an incoming order. It is hereby also
conceivable now, due to the now possible production across
production series and due to the higher volumes resulting from
this, not only to be able to produce the operator's cab mount 121
and the radiator mount 122, which together form the side part 120,
as a welded assembly, but also to be able to manufacture this
module less expensively in alternative processes such as steel
casting or by deep drawing of individual components. It is
conceivable, for example, to be able to utilize this side part 120
as a capacity utilization component on robot down times due to
equipping.
[0038] The main modules of the revolving deck can conceivably be
produced either in welded form or in mutually releasable form. It
is furthermore possible that a combination of both production
processes is used, that is, that some components of the revolving
deck 10 are welded, whereas other components of the revolving deck
10 are in turn releasably connected.
[0039] In a case in which the modules of the revolving deck 10 or
the standardized interfaces are welded to one another or are
releasably connected, it is possible to react to any job changes
still during production of the revolving deck 10 and hereby to be
better able to satisfy customer wishes.
[0040] It is furthermore possible that in a case in which the
modules are releasably connected, a corrosion protection by hot-dip
galvanizing or simple dipping process can already be carried out
before a generally required cutting processing so that the modules
located in production can also be stored outdoors. This makes it
possible to be able to use storage capacities to meet demand and
also to be able to utilize inexpensive storage possibilities.
[0041] It is possible by the modular design of the revolving deck
10 and by the compact dimensions of the components of the revolving
deck 10 to allow a space-saving and thus inexpensive
transportation. It is furthermore also possible to be able to carry
out inexpensive and simple intermediate storage procedures.
[0042] A further advantage due to the modular construction and due
to the releasable connections of the components of the revolving
deck 10 is that in the event of damage only the damaged module of
the revolving deck 10 has to be replaced.
[0043] Note that the figures show various additional structural
features and relative positioning that can provide various
advantages in addition to those specifically identified above.
