Novel split counterweight structure

Abstract

The invention discloses a novel split counterweight structure. The novel split counterweight structure comprises counterweights and a dragging steel wire rope which is connected with the counterweights. The counterweights comprise a first counterweight and N second counterweights, wherein the upper end face of the first counterweight is connected with the dragging steel wire rope, the second counterweights are arranged below the first counterweight in sequence from top to bottom, a rope winding mechanism and a connecting rope connected with the rope winding mechanism are arranged on the upper end face of each second counterweight, the first second counterweight is connected with the lower end face of the first counterweight through the connecting rope arranged on the first second counterweight, the Mth second counterweight is connected with the lower end face of the (M-1)th second counterweight through the connecting rope arranged on the Mth second counterweight, the N is a natural number which is larger than or equal to one, and the M is a natural number which is larger than or equal to two, and is smaller than or equal to the N. According to the novel split counterweight structure, a compensating device does not need to be assembled on an elevator, the change of tension on the two sides of a traction machine of the elevator is small, and a system can be more stable; meanwhile, arrangement of the space of a pit of the elevator and arrangement of a shaft of the elevator are facilitated, the working condition of retention of a lift car can be improved, and damage caused by the phenomenon that the lift car collides with the ceiling of the shaft and collapses to the bottom of the pit is reduced.

Description

technical field [0001] The invention relates to a counterweight structure for an elevator, in particular to a novel split counterweight structure. Background technique [0002] At present, the weight of the car and counterweight of most elevators changes very little. Due to the weight of the traction wire rope, the elevator needs to be equipped with a compensation device to balance the total weight of the car and counterweight to meet the requirements of the traction system. Some elevator compensation devices weigh as much as 2 tons, resulting in a large increase in the weight of the entire system; moreover, the requirements for the traction host will be higher, and other configurations will also increase accordingly, which will eventually lead to the increase in the specifications of each component of the entire system and increase the development of various companies. Cycle and lift costs. The weight of the compensation device affects the development of the entire elevato...
