An elevator counterweight device with associated counterweights and belts

Abstract

The invention discloses an elevator counterweight device with associated counterweights taken out, which belongs to the field of elevator counterweights. A counterweights associated type taken out elevator counterweight device includes a counterweight frame and a counterweight group. The weight group is located inside the counterweight frame. The counterweight frame includes a counterweight frame seat, a counterweight frame top and a pair of counterweight frame sides. A pair of counterweight frame sides are fixedly connected to the left and right ends of the counterweight frame seat. The center of the weight block is drilled from top to bottom with a center jack, and the center of the upper end of the counterweight frame seat is connected with a center column. If necessary, take out multiple counterweights at one time. During the process of taking out and transporting, the relative stability of multiple counterweights can be guaranteed, and it is not easy to slip and hurt the handling personnel, which improves safety and can be reinstalled at one time, greatly shortening the The disassembly and installation time is reduced, the operation efficiency is improved, and the elevator maintenance process is accelerated.

Description

technical field [0001] The invention relates to the field of elevator counterweight devices, and more specifically, relates to a counterweight block associated take-out type elevator counterweight device. Background technique [0002] The counterweight is an integral part of the elevator traction system, and its function is to reduce the power of the traction motor and the torque on the traction wheel and worm wheel. [0003] The structure of the counterweight has no fixed form, but regardless of the form, four guide shoes should be set on the four corners of the counterweight to ensure that the counterweight runs vertically along the counterweight guide rails when the elevator is running. [0004] The counterweight device is located in the hoistway, and is connected with the car through the traction rope through the traction sheave. During the operation of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoe to ...

AI Technical Summary

Problems solved by technology

[0007] In the prior art, when individual counterweights are damaged and need to be disassembled, it is necessary to remove the counterweights one by one from top to bottom, which is time-consuming. If multiple counterweights are taken out at one time, it is easy to take out multiple counterweights Relative sliding occurs, and it is easy to fall and injure the handling personnel; similarly, it is time-consuming and slows down the operation process when reinstalling
