Abstract

The invention discloses an elevator damping device, which comprises a buffer chamber arranged at the bottom of the elevator car, a buffer spring body is arranged at each of the four corners of the buffer chamber, an oil inlet pipe is connected to the buffer chamber, and an oil inlet pipe is arranged on the buffer chamber. The pressure regulating valve, the oil inlet pipe is connected to the oil storage tank through the oil pump, the buffer spring body is provided with a cavity, the cavity is connected to the oil storage tank through the return pipe, and the return pipe is provided with a throttle valve; it also includes a pressure regulating valve respectively , oil pump and throttle valve for communication connection controller. The invention also discloses a damping method of the above-mentioned elevator damping device, which sets two independent active correction processes. The invention can improve the deficiencies of the prior art and improve the damping effect of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator control, in particular to an elevator damping device and a damping method thereof. Background technique [0002] Elevator is an indispensable equipment in people's daily life, and the quality of elevator shock absorption directly affects the ride comfort. Existing damping devices only deal with the damping of the car by designing different elastic damping devices. This damping method can only realize the size of the buffering effect according to the preset selection, and cannot adjust the working characteristics of the entire damping device in real time according to the running situation of the elevator. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator damping device and a damping method thereof, which can solve the deficiencies of the prior art and improve the damping effect of the elevator. [0004] In order to solve th...
