Description
The technical field is as follows:
the utility model relates to a beam boosting device, in particular to a tower crane jacking beam seating boosting device.
Background art:
tower crane is at the in-process that increases the body height of the tower, adopt one set of dedicated hydraulic pressure climbing mechanism to carry out the jacking operation, in the jacking process, need to block jacking crossbeam and last vaulting pole in turn into the body support of the tower and accomplish the jacking operation, the jacking crossbeam is installed at the lower extreme of jacking pneumatic cylinder, when the pneumatic cylinder receipts jar, the jacking crossbeam is automatic to be swung out from the body support of the tower, need the manpower during jacking to push the jacking crossbeam into in the body support of the tower, because the weight of jacking crossbeam and pneumatic cylinder is great, need many people just can accomplish during the promotion, simultaneously when promoting the crossbeam, hydraulic pressure operating personnel stretches out the hydro-cylinder and can make the crossbeam block into the support, if the cooperation of both sides is not good, jacking crossbeam top is along on the support, bad with the support top, cause the accident.
The utility model has the following contents:
the technical problem to be solved by the utility model is as follows: overcome prior art's not enough, provide a tower machine jacking crossbeam booster that comes into seat, through exerting pressure to the pressure bar downwards, the hinged-support rotates and drives the bracing piece and move forward, withstands the jacking crossbeam and promotes forward and get into body of the tower support, convenient to use, easy operation.
The technical scheme adopted by the utility model for solving the technical problem is as follows:
the utility model provides a tower machine jacking crossbeam booster that comes into seat, includes pressure bar, jib and jacking pneumatic cylinder, the upper end and the platform support of jacking pneumatic cylinder are articulated together, the lower extreme and the jacking crossbeam of jacking pneumatic cylinder are articulated together, the right side of jacking crossbeam is provided with back bracing piece, back bracing piece rear end is provided with the guide bar, the guide bar right-hand member is provided with the pressure bar, the pressure bar passes through hinged-support and is in the same place with the lower extreme swing joint of jib, the upper end of jib links together with the bottom of upper mounting plate is perpendicular.
Pressure pole, guide bar and back bracing piece formula structure as an organic whole, the guide bar is the curved shape and distributes.
And the front end of the rear supporting rod is provided with a roller.
The back bracing piece is upper and lower parallel form with the pressure bar and distributes, and guide bar and pressure bar are 120 contained angles.
And a lower platform is arranged below the upper platform.
The utility model has the following positive beneficial effects:
when the tower body support is used, a worker stands on the lower platform, and applies downward pressure to the pressure rod by utilizing the lever principle, the hinged support rotates to drive the support rod to move forwards, the roller at the front end of the rear support rod supports the jacking cross beam to push forwards, so that the jacking cross beam quickly enters the tower body support, and the tower body support is convenient to use, simple to operate and easy to popularize.
Description of the drawings:
figure 1 is a schematic structural view of the present invention,
FIG. 2 is a state diagram of the present invention in use;
in the figure 7 is shown a tower support.
The specific implementation mode is as follows:
the utility model will be further explained and explained with reference to the drawings, in which:
example (b): referring to fig. 1-2, a tower crane jacking crossbeam seating boosting device comprises a pressure rod 1, a suspender 2 and a jacking hydraulic cylinder 8, the upper end of the jacking hydraulic cylinder 8 is hinged with a platform support, the lower end of the jacking hydraulic cylinder 8 is hinged with a jacking crossbeam 6, the right side of the jacking crossbeam 6 is provided with a rear supporting rod 5, the rear end of the rear supporting rod 5 is provided with a guide rod 4, the right end of the guide rod 4 is provided with the pressure rod 1, the pressure rod 1 is movably connected with the lower end of the suspender 2 through a hinged support 3, and the upper end of the suspender 2 is vertically connected with the bottom of an upper platform 9.
The front end of the rear support rod 5 is provided with a roller 11.
The rear support rod 5 and the pressure rod 1 are distributed in an up-and-down parallel manner, and the guide rod 4 and the pressure rod 1 form an included angle of 120 degrees.
A lower platform 10 is arranged below the upper platform 9.
In the above description, under the action of force, the rear support rod pushes the jacking cross beam, and simultaneously the roller at the front end of the rear support rod moves locally along the outer wall of the jacking cross beam.
During operation, operating personnel operates the hydraulic pump and packs up hydraulic cylinder, make the jacking crossbeam reach 7 positions of body of the tower support, then constructor stands on platform down, through exerting pressure downwards on the pressure pole, pressure pole rear end hinge support rotates, drive the guide bar antedisplacement, promote back vaulting pole, back vaulting pole withstands the jacking crossbeam, under the effect of thrust, promote the top of jacking crossbeam inversing body of the tower support, then hydraulic pressure operating personnel stretches out the pneumatic cylinder, in body of the tower support is gone into to the jacking crossbeam card.
The jacking cross beam pushing device has the advantages that the labor is saved, the accidents are avoided, the jacking cross beam can be quickly pushed into the tower body support by utilizing the lever principle, the use is convenient, the operation is simple, and the popularization is easy.
