Description

Technical Field

[0001] The present invention relates to the technical field of elevator pit ladders, and in particular to an elevator pit ladder installation device and a use method thereof. Background Art

[0002] In a traditional elevator pit, a ladder is usually provided for people to enter and exit the pit from the floor door. In the prior art, when the ladder is arranged on the side shaft wall of the floor door, due to the large shaft space required by some elevators, people may still not be able to safely reach the floor door lock device by climbing the ladder, making it difficult for people to leave the pit. In addition, if the elevator pit ladder is directly and immovably set on the shaft wall of the elevator pit, a large distance must be left between the ladder's step and the shaft wall for the foot to step on, which makes the shaft space larger and increases the construction cost. For this reason, some people use hinged connecting rods to allow the ladder to be opened or closed relative to the shaft wall. When the ladder is closed, an additional locking mechanism is required to fix the relative position of the ladder and the shaft wall, reducing the flexibility of the device. Therefore, we redesigned an elevator pit ladder installation device. Summary of the invention
