Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a building construction hoist. Background Art

[0002] Construction elevators are used to transport construction materials or workers to the workplace. The stability of the protective door of the construction elevator after it is closed is more important. For example, a construction elevator protective door disclosed in Chinese patent literature (patent number: CN202320770237.2) has three latch locks, pull ropes and insertion rods. The structure is complex, and the process of fixing the protective door body is cumbersome and prone to errors. Whether the protective door is opened or closed, time will be wasted. If the elevator transports workers, it will only increase the workers' stay time in the elevator. The longer the workers stay in the elevator, the greater the risk.

[0003] For this purpose, we propose a building construction hoist. Utility Model Content

[0009] Preferably, the rear end of the installation shaft is connected to the inner wall of the circular cavity via a bearing, the front end of the installation shaft is connected to the handle, and the installation shaft is movably connected to the right door body.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The handle drives the gear to rotate through the mounting shaft, and the gear cooperates with the teeth set on the top of the slider to push the slider to move to the left. The block set at the left end of the slider will jam the slot set on the left door body. Similarly, turn the handle set on the left door body, and the block set in the left door body will jam the slot set on the right door body, so that the right and left door bodies are quickly closed, and the right and left door bodies are jammed with each other, making the right and left door bodies more stable after closing. At the same time, after the slider pushes the block to jam the slot, the lever hand moves downward by gravity and jams the slider, so that the slider cannot move, thereby ensuring the stability of the elevator protective door after closing. The structure is simple and the stability of the protective door is good after closing.

[0012] 2. Use tools to pry and push the push rod upward. The push rod drives the lever upward, which loosens the fixation on the slider. Turn the handle in the opposite direction. The handle drives the gear to rotate in the opposite direction through the mounting shaft, causing the slider to move in the opposite direction, driving the block out of the bayonet, loosening the fixation on the left door body, thereby quickly opening the right and left door bodies and reducing the time workers stay in the lift.
