Description

Tower crane pedestrian passageway capable of being integrally lifted along with climbing frame

Technical Field

The utility model belongs to the technical field of construction machinery, concretely relates to tower crane pedestrian passageway along with climbing frame whole promotion.

Background

In the construction of high-rise building engineering, a tower crane is the most common hoisting equipment. The tower crane promotes gradually because can be along with the increasing of construction building, though the high tower department still accessible tower crane standard festival ladder bare-handed climbing gets into the tower crane control chamber on duty when lower, nevertheless along with the building constantly risees, the climbing of tower department will become very consuming time and difficulty, not only influences work efficiency, and the potential safety hazard of high altitude climbing is also more outstanding moreover.

Because the tower crane has certain distance from the structure floor, in order to solve the problem of the tower crane, a temporary pedestrian passageway needs to be erected at a proper height between the tower body of the tower crane and the floor of the building so as to shorten the climbing distance of the tower crane. At present, a tower crane pedestrian passageway is generally erected on floors and tower bodies by adopting steel pipes, wood springboards, fasteners, dense mesh nets and the like, the tower crane pedestrian passageway needs to be repeatedly installed and disassembled along with the rising of the height of the tower bodies and the height of the floors, the higher the height of a building, the more times of disassembly and assembly, a large amount of manpower is consumed, and the operation needs to be carried out in the high altitude during erection and disassembly, so that the potential safety hazard is greater. In order to solve the problem that the pedestrian passageway needs to be repeatedly disassembled and assembled, the pedestrian passageway is also manufactured into a plurality of modules, and the modules are assembled after being respectively hoisted to a preset floor, so that the problem of low disassembling and assembling efficiency is solved, the working time of a tower crane still needs to be occupied, the assembling workload is not small, and potential safety hazards still exist in high-altitude installation. Therefore, in the prior art, one end of the pedestrian passageway is fixed on a climbing frame of the tower crane, so that the pedestrian passageway can be lifted along with the climbing frame, and the problems of large workload of disassembly and assembly and high-altitude installation safety are solved. But the pedestrian passageway fixedly installed on the climbing frame is difficult to ensure to be aligned with the standard knot after climbing along with the pedestrian passageway, so that the inconvenience of climbing the tower crane in and out of the standard knot is caused, and the high-altitude safety risk is increased. In order to solve the problem that a pedestrian passageway climbing along with a climbing frame is not aligned with a standard knot, a hinged extension frame is added at the tail end of the pedestrian passageway, but because the extension frame cannot be too long, if the dislocation between the pedestrian passageway and the standard knot is large, the slope is large, an inlet and an outlet are narrow, and the problems of inconvenience in entering and exiting and high altitude safety risk are difficult to eliminate. Also have with the pedestrian passageway with climb the frame articulated, then set up the capstan winch on the frame of climbing of pedestrian passageway top, through the trailing end connection of capstan winch control hawser and pedestrian passageway to realize the adjustment of pedestrian passageway and standard festival linking angle, in order to solve the aforementioned problem that exists. However, it should also be seen that, because the mooring rope is in flexible connection, and the pedestrian passageway of the tower crane is generally erected at a high altitude, the safety of passing the tower crane is affected by a large wind pendulum at the high altitude, and the structural reliability of the hinged part of the pedestrian passageway and the climbing frame is reduced due to long-time frequent shaking of the pedestrian passageway, so that serious potential safety hazards exist.
