Counter weight block joint type taking-out type elevator counter weight device

Abstract

The invention discloses a counter weight block joint type taking-out type elevator counter weight device, and belongs to the field of elevator counter weight devices. The counter weight block joint type taking-out type elevator counter weight device comprises a counter weight frame and a counter weight block set located on the inner side of the counter weight frame. The counter weight frame comprises a counter weight frame base, a counter weight frame roof and a pair of counter weight frame edges, wherein a pair of counter weight frame edges are fixedly connected to the left end and the rightend of the upper side of the counter weight frame base. Center inserting holes are chiseled in the center positions of the counter weight blocks from top to bottom, the center position of the upper end of the counter weight frame base is connected with a center stand column, and the upper end of the center stand column penetrates through the center inserting holes and is in threaded connection with a pressing type fastening nut. According to the scheme, the multiple counter weight blocks can be taken out at a time according to the actual operation requirements, in the taking-out and carrying process, relative stability of the multiple counter weight blocks can be guaranteed, slipping and carrying personnel crushing are not likely to happen, safety is improved, one-time reinstalling can beconducted, the dismounting and mounting time is greatly shortened, the operation efficiency is improved, and the elevator maintaining progress is accelerated.

Description

Technical field [0001] The present invention relates to the field of elevator counterweight devices, and more specifically, to a counterweight block connected 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] There is no fixed form for the counterweight structure, but no matter what 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 rail when the elevator is running. [0004] The counterweight device is located in the hoistway and is connected to the car via the traction rope via the traction sheave. During the operation of the elevator, the counterweight device slides on the counterweight guide rail through the counterweight guide shoes to play a balancing r...

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
