Background technology
In existing demolishing buildings equipment, the dismounting equipment particularly for large-scale chimney, typically by dismantling operation
Platform is sent by the promotion of jacking frame to operation height, since such operation is typically what is completed inside chimney, so just
The number of the increase jacking frame below chimney is needed, is carried by a section number for being incremented by jacking frame to reach operating platform
The height risen, in operating practice, applicant once attempted to realize the promotion of jacking frame by multiple oil cylinders, but due to jacking
Synchronization can not be realized in the process, so frequently resulting in equipment is unable to reach working depth place, working platform face tilts, and work is flat
Platform can not carry out normally be incremented by and remove operation, in addition, equipment fall after rise when due to can not achieve synchronous falling, cause equipment
Often occur stuck phenomenon in the air, normally chimney can not be implemented to remove operation, influence work efficiency.
The content of the invention
A kind of simple and reasonable the invention aims to provide, easy to install and use, oil cylinder is being jacked and fallen after rise
When can realize synchronization, jacking speed is fast, the high multistage thick stick synchronous lifting device of work efficiency.
The object of the present invention is achieved like this, which includes base mechanism, hydraulic cylinder linkage mechanism, multi-cylinder connection
Moving frame, hinged fixed seat and weight body；The base mechanism by square frame structure base body, perpendicular to base body
And the long column of four vertex of base body is arranged on, the intermediate transverse girder and first being connected between two adjacent long columns
Crossbeam is welded on each long column upper end, long column and multiple connector sleeves on the outside of first crossbeam junction and forms；The hydraulic pressure
Cylinder linkage mechanism is by close to long column and four hydraulic cylinders being uniformly vertically set in base body, connecting on each hydraulic cylinder
Oil inlet pipe and counterweight balance oil return pipe, connect the reversal valve of oil inlet pipe and counterweight balance oil return pipe, connect the pumping plant of reversal valve
Form, with non-return valve on the oil inlet pipe, the multi-cylinder linkage frame by four short columns, be connected to two adjacent short columns it
Between second cross beam and the 3rd crossbeam, be arranged on positioning pin on each short column and form；The hinged fixed seat is arranged on often
It is realized below a short column while by articulated shaft with corresponding each hydraulic cylinder upper end hinged；The weight body is by pros
The counterweight phosphor bodies of body structure are formed in criss-cross fashion and perpendicular to the lifting lug of weight body body side setting；It is described to match somebody with somebody
Weight body is arranged on inside multi-cylinder linkage frame.
The present invention has the advantages that：
1st, the present invention on hydraulic cylinder linkage mechanism due to being provided with multi-cylinder linkage frame, while is set again on multi-cylinder linkage frame
Weight body, so that lifting gear can lean on the dead weight of weight body to realize that machinery is same in jacking, particularly when falling after rise
Step, working platform face are not easy to tilt, and equipment can smoothly reach working depth place, and workbench can carry out normally being incremented by
With dismounting operation, particularly equipment synchronous falling can be realized when falling after rise, equipment will not often occur stuck phenomenon in the air,
Work efficiency is high.
2nd, the configuration of the present invention is simple is reasonable, easy to install and use, is particularly suitable for the dismounting operation of large-scale chimney, is chimney
Remove the mating Lifting Equipment of ideal of operation.

Specific embodiment
As shown in attached drawing 1：The lifting gear includes base mechanism 1, hydraulic cylinder linkage mechanism 2, multi-cylinder linkage frame 3, hinged
Fixed seat 4 and weight body 5.
As shown in attached drawing 1,6：The base mechanism 1 by square frame structure base body 1-1, perpendicular to pedestal master
Body 1-1 and the long column 1-2 for being arranged on tetra- vertex of base body 1-1, are connected between the long column 1-2 of adjacent two
Intermediate transverse girder 1-3 and first crossbeam 1-4 is welded on each long column 1-2 upper ends, long column 1-2 and first crossbeam 1-4 junctions
Multiple connector sleeve 1-5 in outside are formed.
As shown in attached drawing 5,6：The hydraulic cylinder linkage mechanism 2 is by close long column 1-2 and is uniformly vertically set on pedestal
Four hydraulic cylinder 2-1 on main body 1-1 connect oil inlet pipe 2-2 and counterweight balance oil return pipe 2-3 on each hydraulic cylinder 2-1, even
The reversal valve 2-4 of oil pipe 2-2 and counterweight balance oil return pipe 2-3 are tapped into, the pumping plant 2-5 of connection reversal valve 2-4 is formed, the oil inlet
Non-return valve 2-6 is carried on pipe 2-2.
As shown in attached drawing 3：The multi-cylinder linkage frame 3 by column 3-1 four short, be connected to two adjacent short column 3-1 it
Between second cross beam 3-2 and the 3rd crossbeam 3-3, be arranged on positioning pin 3-4 on each short column 3-1 and form；It is described hinged solid
Reservation 4 is arranged below each short column 3-1 while is realized by articulated shaft 3-2 with corresponding each hydraulic cylinder 2-1 upper ends
It is hinged.
As shown in attached drawing 4：The weight body 5 in criss-cross fashion and is hung down by the counterweight phosphor bodies 5-1 of cube structure
The lifting lug 5-2 directly set in counterweight phosphor bodies 5-1 sides is formed, and the weight body 5 is arranged on inside multi-cylinder linkage frame 3.
Use process：Multistage thick stick synchronous lifting device of the invention is placed on to the interior lower end of chimney, on base mechanism 1
Multiple outer guiding control frameworks are installed in face by bolt and connector sleeve 1-5, then will be provided with the first segment load-bearing of operating platform
Frame is connected to by the positioning pin 3-4 on multi-cylinder linkage frame 3 on multi-cylinder linkage frame 3, is started hydraulic cylinder linkage mechanism 2, will be commutated
Operation handle on valve 2-4 moves uplink shelves A, such four hydraulic cylinder 2-1 to and starts the synchronous rising that links, and realizes lifting operation；
When reaching an incremental design height, first segment bearing frame by bolt and outer guiding control framework is fixed, then again will
Operation handle moves downlink shelves B on reversal valve 2-4, and such four hydraulic cylinder 2-1, which start to link, synchronously falls back to original position, first
Room area between section bearing frame and multi-cylinder linkage frame 3 sets the second section bearing frame again, repeats above-mentioned action, and so on realization
The alternating installation of more piece bearing frame from the bottom to top, operating platform is finally jacked to predetermined altitude, complete entire lifting operation mistake
