Abstract

The invention discloses an emergency descending system of an elevator. The emergency descending system comprises a frame, a drawing head protection shell and a drawing head fixing hook, wherein a movable drawing head is arranged at the lower part of the frame; the drawing head protection shell is fixedly arranged outside the drawing head; and the drawing head is accommodated in the drawing head protection shell. According to the emergency descending system, the drawing head is protected through the drawing head protection shell arranged outside the drawing head, and unrelated personnel are warned through a warning sign arranged on the surface of the drawing head protection shell, so that the situation of mistaken touch is avoided. The specific use mode of a device is explained through an explanation manual arranged on the surface of the drawing head protection shell, so that the problem that related personnel do not know how to operate in emergency is solved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an emergency descent system of an elevator. Background technique [0002] Elevators are widely used in factories, hotels, restaurants, stations, airport theaters, exhibition halls and other places. They are the best safe companions for maintenance of machinery, paint decoration, replacement of lamps, electrical appliances, cleaning and maintenance, etc. Most of its lifting mechanisms use hydraulic cylinders to control the lifting of the elevator. However, in the event of an accident or emergency (common motor damage), it is difficult to quickly realize the safe descent of the elevator, and the lifting mechanism is set in the Inside the elevator, it is very inconvenient to manually control the expansion and contraction of the hydraulic cylinder. [0003] The existing patent (notification number is CN104512782B) is an emergency descending system of a lift, which includes a suppo...
