Elevator emergency rescue agency

Abstract

The invention discloses an elevator emergency rescue mechanism. The elevator emergency rescue mechanism comprises a traction machine unlocking device, a worm wheel, a worm and a rescue system, when atraction machine is powered off, the traction machine unlocking device acts, thereby causing an electromagnetic braking mechanism of the traction machine to release the braking of the traction machinethrough a digging rope; the worm wheel is coaxially connected to a traction wheel; the worm is meshed with the worm wheel to form a locking mechanism of the traction wheel; the rescue system comprises a driving element which can drive the worm to rotate, and an emergency power supply for supplying power to the driving element; when an elevator is in normal operation, the rescue system keeps the speed ratio of the worm to the worm wheel synchronized with the transmission ratio of the worm to the worm wheel; when the rescue is needed, the rescue system depends on the emergency power supply to rotate the worm, and thus, the traction wheel is driven to rotate through the worm wheel, the lift car approaches to the level to achieve the self-help rescue for passengers. The elevator emergency rescue mechanism can realize the self-help rescue of the passengers, can effectively reduce the maintenance cost of the rescue system, and can greatly improve the safety of the elevator in the event of abnormal conditions such as power failure.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to an elevator emergency rescue mechanism capable of realizing passenger self-rescue. Background technique [0002] In high-rise buildings, the elevator is a necessary accessory equipment, which can bring great convenience to the occupants. At present, with the development of the economy, a large number of middle and high-income groups have emerged, and the demand for villas is also increasing. Correspondingly, home elevators suitable for villa buildings have also become popular. The elevator mainly includes a shaft, a car that can be lifted and lowered in the shaft, and a drive mechanism for driving the car to go up and down. The traction machine is connected to the traction wheel, and a traction rope is wound around the traction wheel. One end of the traction rope is connected to the car, and the other end is connected to a counterweight that can be lifted and lowe...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to solve the problems of untimely rescue, high daily maintenance cost of the rescue system, and potential safety hazards in the braking and rescue methods of the existing elevators when there is a power failure or abnormal situation, and to provide an elevator emergency The rescue organization can realize the self-help rescue of passengers when the system fails or fails, which can effectively reduce the maintenance cost of the rescue system and greatly improve the safety of the elevator in abnormal situations such as power failures.
