Description
FIELD OF INVENTION
[0001] The present invention relates to a precast lightweight wall
panel installation machine for erection and installation of precast
lightweight concrete wall panel. In particular, the machine is
capable for erection and installation of the precast lightweight
concrete wall panel by utilizing frame base mounted with adjustable
slots.
BACKGROUND ART
[0002] In the construction industry, erection and installation of
lightweight concrete wall panel is labor extensive, require
physical strength of workers and involves high risk of injuries
resulted from manual installation by the workers. Moreover, manual
installation provides only 16 m.sup.2/manday which are less
productive and involves high cost of installation. Rough handling
and stress lifting of the concrete wall panel may damage the
concrete wall panel as the workers are required to use physical
strength to lift the concrete wall panel. Further, injury risk
exposure is increased due to the condition of the workers being
fatigue during the installation operation.
[0003] Currently, the existing lifting device being utilize for the
installation of wall panel which is known as "Flat Bed Frame Wall
Panel Lifting Machine" has several drawbacks. The existing machine
is limited for only handling certain load capacity and height of
wall panel. Under certain circumstances, the machine requires more
manpower to flip and lay the wall panel on the lifting frame. The
machine is also unable of installing wall panel above kerbs and
provides low towing handle that may cause obstruction and
difficulty to operate in tight working space.
[0004] Another example of panel transport and erection machine for
a panel such as a wall panel, a magnetic coil panel and the like
which are erected along a track in the track for a linear motor
car, an elevated tire running vehicle and the like is disclosed in
Japanese Patent No. JP 3202260 B2 (JP 260 B2 Patent) entitled
"Panel Transport and Erection Machine" having a filing date of 6
Jun. 1991 (Applicants: Tokai Ryokaku Tetsudo K K; Mitsubishi Heavy
Ind Ltd; Central Japan Railway Co,; Mitsubishi Heavy Ind Ltd). In
the JP 260 B2 Patent, the erection machine comprises a panel to be
erected along a track which is mounted on a mobile trolley that is
capable of mounting the panel. Further, in the JP 260 B2 Patent,
the panel is lifted over to a specified position on the said track
and the erection machine is further made up of a lifting beam which
includes paired clamps which are detachably combined with a lifting
lug section for the panel mounted on the mobile trolley. The JP 260
B2 Patent further disclose paired turning lift arms which rotatably
support both end sections of the lifting beam located close to both
ends of a trolley frame. A working space is needed for lifting out
and erecting the panel as to make it compact in the invention
disclosed in the JP 206 B2 Patent.
[0005] A further example for a lifting operation platform is
disclosed in Chinese Patent Publication No. CN 102910555 A (CN 555
A Publication) entitled "Micro Travel Lifting Operation Platform"
having a filing date of 9 Oct. 2012 (Applicant: Hubei Guorui
Intelligent Equipment Co. Ltd). The CN 555 A Publication provides a
micro travel lifting operation platform which comprises a base, an
operation platform, an electric system and a lifting system. The
lifting system supports the operation platform and comprises a
cylinder with a lock, a guide mechanism and a plurality of groups
of chain wheel lifting mechanisms driven by the cylinder. The chain
wheel lifting mechanisms as disclosed in the CN 555 A Publication
are electrically connected with one another through the electric
system and matched with one another to be operated. The micro
travel lifting operation platform provides that the internal force
of the systems is only the dead weight of the operation platform
and personnel. The operation platform proposed in the CN 555 A
Publication also provides with a lifting in place detection switch
to detect if the operation platform is lifted in place and the
stability of the operation platform as well as the safety of
operating personnel are guaranteed through a pneumatic mechanical
self-locking cylinder.
[0006] Another mechanism that provides the loading and unloading
platform is disclosed in Chinese Patent Publication No. CN
105712105 A (CN 105 A Publication) entitled "Internal Folding Type
Loading and Unloading Platform" having a filing date of 14 Apr.
2016 (Applicant: Shanghai Bdh Logistic Facilities & Eng Co
Ltd). The CN 105 A Publication proposed an internal folding type
loading and unloading platform used for a cold-chain logistics
warehouse or an iso-temperature warehouse. The internal folding
type loading and unloading platform disclosed in the CN 105 A
Publication can be disposed inside the cold-chain logistics
warehouse or the iso-temperature warehouse. The internal folding
type loading and unloading platform disclosed in the CN 105 A
Publication is disposed on a mounting frame in a reserved
foundation pit which is downward from a floor level and close to a
doorway of the warehouse in the warehouse. The internal folding
type loading and unloading platform comprises a main face plate, a
butt strap, a platform surface assembly oil cylinder, a butt strap
oil cylinder, a hydraulic power unit and an electrically operated
control box. The main face plate and the butt strap are arranged
approximately in parallel. The electrically operated control box
sends an instruction to the hydraulic power unit so as to control
the platform surface assembly oil cylinder and the butt strap oil
cylinder to operate, and a loading and unloading platform surface
is switched between an internally folded state and an extending
state to adjust the lifting amplitude of the main face plate and
the butt strap.
[0007] A further example which introduces lifting loading platform
is disclosed in International Patent Publication No. WO 2010/031511
A1 (WO 2010/031511 A1 Publication) entitled "Lifting Loading
Platform" having a filing date of 8 Sep. 2009 (Applicant: MBB
Palfinger Gmbh). The WO 2010/031511 A1 Publication disclosed
lifting loading platforms for trucks having a loading platform that
can be lifted and lowered and pivoted by means of a lifting unit.
The lifting unit of WO 2010/031511 A1 Publication comprises a
hydraulic cylinder for the lifting and lowering and for the
pivoting of the lifting loading platform whereby the operation of
the hydraulic cylinder requires a hydraulic unit and relatively
large hydraulic lines. The invention in the WO 2010/031511 A1
Publication further provides a lifting loading platform, whereby
the loading platform is lifted, lowered, and pivoted by means of
electric linear drives. The linear drives are equipped in a
particular manner with a plurality of rod-shaped electric motors
mutually driving a toothed gear. A spindle nut can be rotated on a
threaded spindle by the toothed gear. In this manner the threaded
spindle can be axially displaced in the manner of piston rods of
hydraulic cylinders. Due to the electrically operated linear drives
the lifting loading platform according to the invention requires no
hydraulic unit, and therefore also no hydraulic lines.
[0008] Therefore, there is a need to build a machine with special
features for lifting a concrete wall panel which enhances
productivity and efficiency, safe and minimizes installation
cost.
