Abstract
Description
Technical Field
[0001] The utility model belongs to the field of rescue devices, in particular to an elevator rescue device. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid guide rails with a vertical or inclined angle of less than fifteen degrees. There are many types of elevators according to different uses, such as elevators, escalators, freight elevators, medical elevators, sightseeing elevators, etc. The core components of the elevator include traction machines, traction ropes, cars, counterweights, guide rails, etc. When the elevator is running, the traction machine drives the traction wheel to rotate, thereby driving the elevator to move up and down. The safety performance of the elevator is very important and needs to be inspected and maintained regularly. When a malfunction occurs in the elevator, the elevator car 101 often stops in the middle of the elevator door 100. When rescuing trapped passengers, if the staff and passengers lack common sense of safe operating specifications, the elevator will suddenly continue to work during the rescue process. It will endanger the safety of the passengers. Therefore, we have designed an elevator rescue device. Utility Model Content
