Waterproof and freeze-proofing elevator bumper

Abstract

The invention discloses a waterproof and freeze-proofing elevator bumper. The waterproof and freeze-proofing elevator bumper comprises a buffering cylinder, a buffering board, a spring seat, a return spring pressed between the buffering board and the spring seat, a heating device, a temperature sensor used for detecting the environment temperature and a controller connected with the heating device and the temperature sensor; the buffering cylinder comprises a piston, a cylinder body, a hydraulic oil tank and a pressure release valve for cutting off a communication channel between the hydraulic oil tank and the cylinder body; the cylinder body is filled with hydraulic oil; the buffering board and the free end of the piston are fixedly connected; spring buffer rubber is arranged on the upper plane of the buffering board; and the heating device switch-on temperature range preset by the controller is from 0 to -10 DEG C, and the switch-off temperature range is from 15 DEG C to 25 DEG C. The heating device is arranged on the cylinder body, so that the hydraulic oil is automatically heated at low temperature, the hydraulic oil can keep a good working state for a long time accordingly, the buffering effect of the bumper is ensured, the safety performance of usage of an elevator is improved, and the service life of the hydraulic oil is prolonged advantageously.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a waterproof and antifreeze elevator buffer. Background technique [0002] Elevator is a kind of machine for people and goods transportation, which greatly facilitates passengers and vertical goods transportation. It is mainly composed of control system, circuit, transportation mechanism and load-bearing structure. Elevators are divided into indoor elevators and outdoor open-air elevators according to the use environment; As the last line of defense of the elevator safety system, the buffer acts as a buffer when the elevator fails, so as to relieve the elevator or people in the elevator from direct impact. The low temperature environment in winter tends to cause the buffer hydraulic oil to solidify, which is not conducive to the performance of the buffer. The cushioning effect reduces the safety performance of elevators, especially open-air elevators. Contents of the inventio...
