Description
Technical Field
[0001] The utility model relates to the technical field of tower crane safety auxiliary devices, in particular to a telescopic tower crane safety passage. Background Art
[0002] Tower cranes are common lifting equipment used in construction. Crane operators and maintenance personnel must access the crane's operating room via a ladder within the crane's standard section. To facilitate quick and safe access, a conventional approach is to construct a safety passage between the building and the crane's standard section. Existing safety passages for tower cranes are typically constructed by laying steel pipes, scaffolding, or wire mesh between the building and the crane's standard section.
[0003] When installing and using the existing tower crane safety passage, since it is not a modular assembly structure, the size of the passage needs to be customized according to the distance between the tower crane and the attached wall, the cost is high, and it cannot be reused; since the protection range cannot be changed, the application scope of the passage is limited and the functionality of the passage is relatively low, which has a certain adverse effect on people's use process. In order to solve the shortcomings of the existing technology, we propose a retractable tower crane safety passage. Utility Model Content
[0004] The main purpose of the utility model is to provide a retractable tower crane safety passage, which can effectively solve the problems in the background technology.

DETAILED DESCRIPTION
[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.
[0022] like Figure 1 As shown, Figure 1 This is a schematic diagram of the assembly effect of two groups of pass steel plates 6. A receiving groove for accommodating the pass steel plate 6 is provided inside the other side of the pass steel plate 6. An adjustment plate 1 is welded on one side of the pass steel plate 6. The other end of the adjustment plate 1 is embedded in the receiving groove inside the other group of pass steel plates 6. The second protective rod 9 is embedded in the first protective rod 5.
