Elevator counterweight block and installation method thereof

Abstract

The invention belongs to the technical field of elevator parts, and particularly relates to an elevator counterweight block and an installation method thereof. The elevator counterweight block comprises two counterweight block single bodies, grooves are symmetrically formed in the surfaces of one ends of the counterweight block single bodies, a first boss is arranged on one side of each counterweight block single body, a second boss is arranged in the middle of the other side of each counterweight block single body, threaded channels are formed in the first bosses and, the threaded channels penetrate through the first bosses. According to the elevator counterweight block, the two elevator counterweight blocks are spliced, so that installation personnel can more quickly and effectively mount the counterweight blocks into a counterweight housing, and the problem of car sliding caused by unbalance of a lift car during operation due to insufficient self weight of a counterweight is solved; and a screw rod is matched with a nut, so that the tightness between the two elevator counterweight blocks is enhanced through connection, and an elevator is prevented from falling off during operation.

Description

technical field [0001] The invention belongs to the technical field of elevator components, and relates to an elevator counterweight and an installation method thereof. Background technique [0002] The function of the elevator to the weight is to balance the weight of the car, so that the traction device can control the up and down movement of the elevator car with relatively small power and pulling force. Depending on the purpose and size of the elevator car, the required elevator counterweights are different. [0003] At present, there is a common disadvantage of the elevator counterweight. Since the elevator counterweight is a whole piece, when the thickness of the elevator counterweight is too large, the top counterweight cannot be installed into the counterweight frame, resulting in the counterweight self-weight Insufficient and other problems, most elevator manufacturers have to open a gap on the counterweight column and put in the counterweight, which seriously affe...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an elevator counterweight and its installation method, which can avoid the counterweight column by splicing two elevator counterweights The upper gap effectively solves the problem that the counterweight cannot be installed on the top of the counterweight frame, and solves the problem that the counterweight frame shakes when the elevator is running due to insufficient self-weight, and also enables the installer to quickly and effectively align the weight Loaded into the counterweight frame; by using the screw and the nut to connect and strengthen the tightness between the two elevator counterweights to prevent the elevator from falling off during operation
