The wall-mounted placer according to the present invention comprises a pillar, supporting frames and a placing boom, with the pillar fitted through the supporting frames and the placing boom arranged at the top end of the pillar, wherein the supporting frames and a base provided at the bottom of the pillar are fixed to a wall by means of fixing devices.
Full Text FIELD OF THE INVENTION
The present invention relates to the field of construction machinery, in particular to a
placer adapted for placing concrete.
BACKGROUND OF THE INVENTION
Currently, during construction operations, placers are conventionally used for
placing concrete to construct walls and floors. Prior art placers may be generally classified
into three types:
1. Floor-mounted placer. As shown in Fig. 1, at first, mounting holes with
predetermined sizes are pre-defined in floors such that at least three supporting frames may
be fitted into these predefined mounting holes in respective building floors 12 via
expansion bolts; afterwards, wedges are used to fix the placer to the supporting frames.
Such a placer is mainly disadvantageous in that: firstly, it is required to provide holes in
floors 12 in advance and to block these holes after the placer has climbed up; secondly, the
floor-mounted placer can only be mounted on a floor lower than the topmost floor since the
fresh topmost floor may not be strong enough to hold the placer, thus imposing a limit on
the operation height of the placer; thirdly, for some high buildings, it is the walls that need
to be developed prior to floors, and these walls are often much higher than floors, therefore
a relative high wall may not be constructed with a floor-mounted placer.
2. Floor-standing placer. As shown in Fig. 2, legs 17 of the floor-standing placer rest
on the floor. Such a placer is mainly disadvantageous in that the operating radius of placing
boom of the floor-standing placer 14 is less than 19 m. Restricted by the small radius, it is
necessary to relocate the placer and to reinstall concrete delivery pipes when another
placing area is desired.
3. Hoistway-placer. As shown in Fig. 3, hoistways 18 are usually provided in core
regions of buildings. Such a hoistway-placer 15 is mainly disadvantageous in that: the
placer is located in a core region of the building and can only cover said building. If it is
desired to carry out operation on a neighboring building, the hoistway-placer has to be
2

moved and reinstalled, while a wall-mounted placer 16 may carry out operation on a
neighboring building without any movement.
SUMMARY OF THE INVENTION
The present invention is intended to solve the problems in the prior art, and
provides a wall-mounted placer which can be installed in a convenient way, may be lifted
along walls, and have a larger operation area.

cylinders, a supporting device, pluralities of supporting members arranged on the pillar and
abutments, such that the abutments are arranged on the supporting frame and are
symmetrically mounted on both sides of the pillar, the jacking cylinders are arranged on the
abutments, the supporting device is arranged on a piston rod of the jacking cylinder and
cooperates with the supporting member, and the blocker is arranged on the abutments, with
one end thereof engaged to the abutment and the other end arranged between two
supporting members.
The supporting members are designed as pluralities of rigid tubes arranged on the
pillar, with a supporting stub provided in the rigid tube above the piston rods, and wherein
the supporting devices are designed as fixed supporting blocks which are arranged on the
piston rods and cooperate with the supporting stubs.
The supporting members are designed as pluralities of fixed stoppers arranged on
the pillar, and the supporting device comprises a supporting bracket and a rotating stopper
arranged thereon and cooperating with the fixed stopper, such that one end of the rotating
stopper is hinged to the supporting bracket, and the other end thereof is arranged between
3

two fixed stoppers.
One end of the blockers is hinged to the abutment, and the other end thereof is
arranged between two supporting member, with the end hinged to the abutment provided
with a return spring connected to the abutments.
A guide groove with an internal compression spring therein is defined in the

Operation principle of the first embodiment of the present invention
At first, pre-embedded parts 6 are provided in walls 10 during placing. Afterwards,
both the base 1 and the supporting frames 5 are fixed onto the wall 10 by means of the
fixing devices 9 and the pre-embedded parts 6, so that the placer may be fixed to the wall
10 to form a wall-mounted placer. The fixing devices 9 are provided with elongated holes
91 to eliminate embedding errors of the pre-embedded parts 6 and to ensure a precise
installation of the placer. With the wall height increasing, the placer becomes not high
enough to meet operational requirements. At this point, the jacking assembly 4 may be
utilized to jack up the placer. During the operation of the jacking assembly 4, at first, both
supporting stubs 462 are respectively inserted into ends of the rigid tubes 461 of the pillar
2, and the moving ends of the jacking cylinders 42 are respectively connected with the
supporting stubs 462; then the fasteners 8 between the pillar 2 and the supporting frames 5
are removed, and the fixing devices 9 connecting the base 1 with the wall 10 are also
removed; thereafter, the jacking cylinders 42 jack up the supporting stubs 462, which
causes the placer to rise. During the jacking process, the rigid tube 461 below the blocker
41 pushes the blocker 41 to rotate in the arrow direction shown in Fig. 6 and causes the
return spring 44 to get stretched; after the rigid tube 461 passes across the blocker 41, the
latter will restore its original occupation automatically by the return spring 44. If the piston
rods 47 of the jacking cylinders 42 starts to retract, the rigid tube 461 drops back onto the
blocker 41. The blocker 41 blocks the rigid tube 461 from further movement and thus holds
the placer. Next, the supporting stubs 462 are pulled out, re-inserted into a rigid tube 461
closer to the piston rods 47, and re-connected to the piston rods 47. Thus the next jacking
process can be repeated in a similar way as described above. The jacking process is
repeated until the placer is jacked up to a desired operation height. At this point, the
fasteners 8 are refitted into position, and the base 1 is fixed to the wall 10 by fixing devices
9. Thus, the jacking process of the placer is completed. After the jacking process, the
8

jacking assemblies 4 are situated in a lower position with respect to the pillar 2. To
facilitate a future jacking, it is necessary to lift the supporting frames 5 by a certain height
with the lifting device 7. During the lifting process, the wires 76 are connected with the
lifting ring 51 of the highest supporting frame 5, and the fasteners 8 between the highest
supporting frame 5 and the pillar 2 as well as the fixing device 9 connecting the highest
supporting frame 5 to the wall 10 are removed, so that the highest supporting frame 5 can
be suspended by wires 76. Afterwards, the drive unit 73 is activated such that chains 72
and wires 76 may be driven by the sprocket 75 to lift the highest supporting frame 5. After
the highest supporting frame 5 gets into position, the drive unit 73 will be turned off, the
fasteners 8 between the supporting frame 5 and the pillar 2 will be fitted, and the highest
supporting frame 5 will be disconnected from the wires 76. In this way, the lifting process
for the highest supporting frame 5 is completed. To lift the next supporting frame 5, wires
76 are connected with the next supporting frame 5 via the guide pulley 52, the fasteners 8
between the supporting frame 5 and the pillar 2 as well as the fixing device 9 connecting
the supporting frame 5 to the wall 10 are removed, the drive unit 73 is activated, and the
supporting frame 5 is lifted. After the supporting frame 5 gets into position, the drive unit
73 is turned off, and the fasteners 8 between the supporting frame 5 and the pillar 2 are
refitted, such that the lifting process is completed. The fixing devices 9, the jacking
assemblies 4 and the lifting device 7 cooperate with each other, such that the placer may be
fixed on the wall 10 and may be raised with a rising wall 10 to meet requirements for an
engineering construction.

pillar 2 is further provided with a jacking assembly 4, which comprises a blocker 41,
jacking cylinders 42, supporting devices 45, pluralities of supporting members 46 arranged
on the pillar 2 and abutments 43 symmetrically arranged on both sides of the pillar 2,
wherein the jacking cylinders 42 are arranged on the abutments 43, and the supporting
device 45 is provided on a piston rod 47 of the jacking cylinder 42 and cooperates with the
supporting member 46. A guide groove 431, in which a compression spring 48 is provided,
is defined in the abutment 43. One end of the blocker 41 is arranged in the guide groove
431 and is engaged with the compression spring 48, and the other end the blocker 41 is
arranged between two supporting members 46. The supporting members 46 are designed as
pluralities of fixed stoppers 463 arranged on the pillar 2. The supporting device 45
comprises a supporting bracket 453 and a rotating stopper 452 arranged thereon and
cooperating with the fixed stopper 463. One end of the rotating stopper 452 is hinged to the
supporting bracket 453, and the other end thereof is arranged between two fixed stoppers
463. When the pillar 2 of the placer is jacked up, both the blocker 41 and the fixed stoppers
463 are in the way of the rigid tubes 461. When the placer is at rest, the pillar 2 of the
placer is held in position by the fixed stopper 23 on the blocker 41. During the jacking
process, a fixed stopper 463 below the blocker 41 pushes the blocker 41 to rotate in the
arrow direction as shown in Fig. 13, and after the fixed stopper 463 passes across the
blocker 41, the latter will restore its original occupation automatically by the compression
spring 48. A lifting assembly 7 is attached to the pillar 2. The lifting assembly 7 comprises
lifting cables 71, a drive unit 73, and rollers 74 designed as sprockets 75 in the present
embodiment for purpose of higher transmission efficiency and slip-resistance of the lifting
cables 71. The lifting cable 71 comprises at the respective ends thereof a wire 76 connected
with the supporting frame 5 and a chain 72 wounded on the sprocket 75. The drive unit 73
10

is arranged at the upper end of the pillar 2 of the placer, and comprises an output shaft
coupled to the sprockets 75. The chain 72 has a sufficient length such that the supporting
frame 5 may to be lifted into a desired position. The supporting frame 5 is provided with
guide pulleys 52 and a lifting ring 51 cooperating with the lifting cables 71.
Operation principle of the second embodiment of the present invention
At first, pre-embedded parts 6 are provided in walls 10 during placing. Afterwards,
both the base 1 and the supporting frames 5 are fixed onto the wall 10 by means of the
fixing devices 9 and the pre-embedded parts 6, so that the placer may be fixed to the wall
10 to form a wall-mounted placer. The fixing devices 9 are provided with elongated holes
91 to eliminate embedding errors of the pre-embedded parts 6 and to ensure a precise
installation of the placer. With the wall height increasing, the placer becomes not high
enough to meet operational requirements. At this point, the jacking assembly 4 may be
utilized to jack up the placer. Before the jacking operation, the fasteners 8 between the
pillar 2 and the supporting frames 5 are removed, and the fixing devices 9 connecting the
base 1 with the wall 10 are also removed; thereafter, the jacking cylinders 42 jack up the
supporting stubs 462, causing the placer to rise. During the jacking process, the fixed
stopper 463 below the blocker 41 pushes the blocker 41 to rotate in the arrow direction
shown in Fig. 13; after the fixed stopper 463 passes across the blocker 41, the latter will
restore its original occupation automatically by the compression spring 48. If the placer
needs to be jacked up further when the piston rod 47 of the jacking cylinder 4 has reached
its maximum stroke, the piston rod 47 will start to retract. At this time, the fixed stopper is
disengaged from the rotating stopper 452, and the placer is held in position by the blocker
41. The piston rod 47 moves downwardly continuously with the supporting bracket 453
and the rotating stopper 452 thereon. If the rotating stopper 452 comes across a lower fixed
stopper 463, it may be pushed by the fixed stopper 463 to rotate in the arrow direction
shown in Fig. 14. After the rotating stopper 452 passes across the fixed stopper 463, the
former will restore its original occupation automatically by gravity. After the piston rod 47
11

completes its retraction, the jacking assembly may start a new jacking cycle. The jacking
cycle is repeated until the placer is lifted to a desired operation height. At this point, the
fasteners 8 are refitted into position, and the base 1 is fixed to the wall 10 by fixing devices
9. Thus, the jacking process of the placer is completed. When the placer is at rest, the pillar
2 is held in position by the fixed stopper 463 on the blocker 41. And if no more jacking is
required, fasteners 8 may be re-fitted between the supporting frame 5 and the pillar 2. After
the jacking process, the jacking assemblies 4 are situated in a lower position with respect to
the pillar 2. To facilitate a future jacking, it is necessary to lift the supporting frames 5 by a
certain height with the lifting device 7. During the lifting process, the wires 76 are
connected with the lifting ring 51 of the highest supporting frame 5, and the fasteners 8
between the highest supporting frame 5 and the pillar 2 as well as the fixing device 9
connecting the highest supporting frame 5 to the wall 10 are removed, so that the highest
supporting frame 5 can be suspended by wires 76. Afterwards, the drive unit 73 is activated
such that chains 72 and wires 76 may be driven by the sprocket 75 to lift the highest
supporting frame 5. After the highest supporting frame 5 gets into position, the drive unit
73 will be turned off, the fasteners 8 between the supporting frame 5 and the pillar 2 will
be fitted, and the highest supporting frame 5 will be disconnected from the wires 76. In this
way, the lifting process for the highest supporting frame 5 is completed. To lift the next
supporting frame 5, wires 76 are connected with the next supporting frame 5 via the guide
pulley 52, the fasteners 8 between the supporting frame 5 and the pillar 2 as well as the
fixing device 9 connecting the supporting frame 5 to the wall 10 are removed, the drive
unit 73 is activated, and the supporting frame 5 is lifted. After the supporting frame 5 gets
into position, the drive unit 73 is turned off, and the fasteners 8 between the supporting
frame 5 and the pillar 2 are refitted, such that the lifting process is completed. The fixing
devices 9, the jacking assemblies 4 and the lifting device 7 cooperate with each other, such
that the placer may be fixed on the wall 10 and may be raised with a rising wall 10 to meet
requirements for an engineering construction.
