Abstract

The invention relates to the technical field of elevators, in particular to a counterweight for a traction elevator. The counterweight comprises a diversion sheave, a counterweight frame connected with the diversion sheave, a plurality of counterweight fillers arranged on the counterweight frame, a guide shoe and an extending frame. The guide shoe and the extending frame are arranged on the counterweight frame. A screw is arranged on a bottom frame of the counterweight frame. All the counterweight fillers are provided with inner threaded holes, thereby being in threaded connection with the screw. The counterweight fillers comprise bodies and gaskets, and the gaskets are arranged on the top faces and the bottom faces of the bodies correspondingly. The gaskets comprise dish-shaped anti-looseparts, and the inner threaded holes are the centers of the anti-loose parts. The counterweight is stable in structure, and the problems of mutual collision and damage caused by looseness of the counterweight fillers in the operation process of the elevator can be solved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a counterweight device for traction elevators. Background technique [0002] The elevator counterweight is also called the gravity balance system, which is a component of the elevator traction system. Its main function is to balance the weight of the car, and keep the weight difference between the car and the counterweight within the limit during the elevator operation. , to ensure that the traction drive of the elevator is normal. The elevator counterweight is located on the other side of the car and is connected to the car roof by a traction wire rope. The counterweight plays an energy-saving role in the elevator traction system, so the theoretical calculation before the counterweight optimizes the elevator load. [0003] In the existing elevator structure, there are usually more than two counterweights. When the elevator moves at high speed, the counterweights will loosen,...
