Self-lifting mounting platform for steel head material hoister and mounting method for mounting platform

Abstract

The invention discloses a self-lifting mounting platform for a steel head material hoister and a mounting method for the mounting platform. The mounting platform comprises hooks, lifting rope winding systems, a lifting platform body and a lifting power mechanism, the hooks are hung on highest horizontal rods of a steel head, the lifting power mechanism is connected with the other ends of the hooks through the lifting rope winding systems so that the lifting platform body ascends and descends relative to guide rails in the steel head, lifting platform guide wheels, rotatable anti-fall safety tools and limiting plates are arranged on the lifting platform body, the lifting platform guide wheels are capable of sliding on the guide rails in the steel head, the limiting plates are used for limiting the anti-fall safety tools to rotate, and stop and support plates for supporting the lifting platform body is arranged on the guide rails in the steel head. The mounting method includes a mounting and ascending step and a demounting and descending step. The mounting platform and the mounting method are capable of effectively avoiding construction safety accidents and guaranteeing personal safety of workers. The self-lifting mounting platform for the steel head material hoister which is excellent in performance and the mounting method for the mounting platform are applied to the building industry.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to a self-elevating steel derrick material hoist installation platform and an installation method thereof. Background technique [0002] The frame body of the derrick material hoist on the construction site continues to increase following the building under construction, and the height can generally reach nearly 100 meters. In the prior art, there is no self-elevating operation platform for the frame body installation and disassembly of the derrick material hoist on the construction site. The bridge deck is only laid on the upper part of the top section. The operator has no railings to protect himself and the safety belt on his body cannot realize "high hanging and low use". This is a very dangerous high-risk operation. Since there is no railing for body protection and the safety belt can only be tied to the steel derrick rods below the bridge deck where the feet stand, the sa...

AI Technical Summary

Problems solved by technology

[0003] The traditional derrick installation platform is only the bridge deck laid on the derrick. This traditional installation platform and installation method cannot solve the problem of installation without guard rails and the safety protection function of "high hanging and low use" of safety belts cannot be realized.
