Abstract
The utility model relates to a jacking anti-separation device which comprises a lower platform, frames, standard knots, a jacking cylinder, a jacking cross beam and an anti-separation mechanism, wherein the lower platform is fixedly connected with the tops of the standard knots; the two frames are arranged outside the standard knots; the lower platform is fixedly connected with the frame at the upper part; the two ends of the jacking cylinder are fixed with the frames; pulleys are arranged at the bottoms of the frames, and propped against the standard knots; the standard knots are fixed with the jacking cross beam through the anti-separation mechanism; a pin shaft is arranged at one end part of the jacking cross beam. The jacking anti-separation device has the advantages that a bolt type anti-separation structure is fixed on jacking cross beam, and clamped on main limbs of the standard knots, so that the separation force of the jacking cross beam is controlled, and the condition that the jacking cross beam is separated from pedals of the standard knots is avoided, which avoids the collapse of the whole machine, and enhances the safety performance.
Description
Technical field
The utility model relates to tower crane technical field, relates in particular to a kind of jacking falling-off prevention device.
Background technology
Safety when tower crane lifting supernumerary segment.Lifting guide support adding is the important process link that tower crane is installed, if design unreasonablely or without anti-drop device, likely can make jacking cross beam deviate from the standard knot arc groove of marking time in installation process, causes complete machine to fall down, and has certain potential safety hazard.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model is to provide a kind of jacking falling-off prevention device, improves operational security.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of jacking falling-off prevention device, comprise lower platform, stock, standard knot, jacking cylinder, jacking cross beam, escapement, lower platform is fixedly connected with standard knot top, two stocks are arranged on standard knot outside, lower platform is fixedly connected with the stock that is arranged on top, and jacking cylinder two ends are all fixed with stock; Described stock bottom is equipped with pulley, and described pulley is resisted against on standard knot; Standard knot and jacking cross beam are fixed by escapement, and jacking cross beam end is provided with bearing pin.
Described escapement comprises anticreep bolt, and anticreep bolt is L shaped structure, and short side part end is provided with groove, and short side part is divided into axle rotation with long leg.
Compared with prior art, the beneficial effects of the utility model are:
Be fixed on jacking cross beam with bolt formula disconnecting prevention structure, in work, snap on standard section main limb, controlled jacking cross beam and deviate from power, avoided jacking cross beam to deviate from standard knot pedal, and then avoided collapsing of complete machine, strengthened safety performance.

In figure: the main limb 10-of 1-lower platform 2-stock 3-standard knot 4-jacking cylinder 5-escapement 6-jacking cross beam 7-anticreep bolt 8-pedal 9-bearing pin.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following embodiment.
See Fig. 1-Fig. 3, jacking falling-off prevention device, comprise lower platform 1, stock 2, standard knot 3, jacking cylinder 4, jacking cross beam 6, escapement 5, lower platform 1 is fixedly connected with standard knot 3 tops, two stocks 2 are arranged on standard knot 3 outsides, lower platform 1 is fixedly connected with the stock 2 that is arranged on top, and jacking cylinder 4 two ends are all fixed with stock 2; Described stock 2 bottoms are equipped with pulley, and described pulley is resisted against on standard knot 3; Standard knot 3 is fixed by escapement with jacking cross beam 6, and jacking cross beam 9 ends are provided with bearing pin 10.
Described escapement comprises anticreep bolt 7, and anticreep bolt 7 is L shaped structure, and short side part end is provided with groove, and short side part is divided into axle rotation with long leg, and groove is stuck on standard knot 3.
When use, stock 2 arrives job position by jacking cylinder 4 jackings, when the bearing pin 10 of jacking weighing apparatus beam 6 falls into the nest of standard knot pedal 8, rotary release proof bolt 7, the groove of anticreep bolt 7 blocks standard section main limb 9, after completing jacking, safety block is opened and is implemented, and rotary release proof bolt mouth is to interior side direction, and oil cylinder shrinks.
The utility model utilizes location, tower machine standard section main limb angle steel limit, guarantees the safety of tower machine in the time of lifting guide support adding; Be fixed on jacking cross beam with bolt formula disconnecting prevention structure, in work, snap on standard section main limb, controlled jacking cross beam and deviate from power, avoided jacking cross beam to deviate from standard knot pedal, and then avoided collapsing of complete machine, strengthened safety performance.
