Novel lift counterweight device

Abstract

The invention provides a novel lift counterweight device and belongs to the technical field of lifts. The novel lift counterweight device comprises a frame, a rope connecting part arranged on the frame, a sliding counterweight block with the two ends being provided with limiting supports, and a magnetic buffer part, and further comprises an acceleration sensor, wherein the frame comprises two sidewalls arranged in parallel, and a fixing beam connected with the two side walls; sliding chutes are arranged on the side walls; the cross section of the sliding chutes is in a cross shape; the limiting supports are contained in the sliding chutes correspondingly; first buffer parts are arranged at the lower end of the sliding counterweight block; the magnetic buffer part comprises a fixing part and an elastic part; and the fixing part is provided with a concave surface capable of containing the elastic part. By arranging the cross section of the sliding chutes in the cross shape, the effect that the sliding counterweight block is not deviated from a track during downward sliding is ensured, impact force caused by sudden weightlessness can be decomposed by the multiple first buffer parts,the good buffer effect is achieved, the novel lift counterweight device is good in damping performance, and the safety performance of a lift during accidents is high.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a novel elevator counterweight device. Background technique [0002] Generally, elevators use counterweights. Modern elevators are mainly composed of traction machines (winches), guide rails, counterweight devices, safety devices (such as speed governors, safety gears and buffers, etc.), signal control systems, cars and hall doors. However, the general hydraulic elevator does not have a counterweight device. [0003] In the elevators currently in use, the counterweight device is an indispensable part of the traction elevator. By balancing the weight of the car and part of the weight of the elevator load, the loss of motor power is reduced. [0004] The counterweight device of an ordinary elevator includes two upper side beams, two vertical beams, two lower side beams, a counterweight iron platen and a counterweight iron. The two vertical beams are parallel to each other. Th...
