Description

Technical Field

[0001] The invention belongs to the field of construction elevators, and in particular relates to an installation and disassembly device for a construction elevator. Background Art

[0002] Construction hoists are widely used in the construction industry, responsible for the vertical transportation of cargo. They primarily consist of a guide rail frame, cage, trolley frame, and guardrails. Traditional construction hoists, in the absence of other large-scale lifting equipment, rely on the cage's built-in electric boom for high-altitude installation and disassembly.

[0003] Traditional construction elevators generally have a cage on each side of the guide rail frame, but in the construction of super-high-rise buildings, multiple traditional construction elevators are generally required, which will occupy a large amount of construction space. Monorail multi-cage circulating construction elevators install track-switchable rotating sections at the upper and lower ends and in the middle of the elevator's guide rail frame. The cage can be switched from one track to the other at the rotating section, thereby realizing the circulation of multiple cages on a single track. This not only occupies a smaller construction space, but also greatly improves its vertical transportation capacity. However, the rotating sections and other structural components of the monorail multi-cage circulating construction elevator are heavy, and the electric boom on the cage top has limited lifting capacity. In the absence of other large-scale lifting equipment, the electric boom on the cage top cannot be used for installation and disassembly at high altitudes. Summary of the Invention
