Elevator counterweight device

Abstract

The invention discloses an elevator counterweight device which comprises a counterweight housing, the counterweight housing comprises an upper frame, a lower frame and side frames, and each of the upper frame and the lower frame comprises two strip-shaped inwards-rolled bent steel plates which are arranged in parallel and bent; any one of the inwards-rolled and bent steel plates is formed by bending a strip-shaped steel plate in the same direction at a right angle and then bending the strip-shaped steel plate in the opposite direction at a right angle, and the side frame comprises two strip-shaped outwards-rolled and bent steel plates which are vertically arranged in parallel; any one of the outwards-rolled bent steel plates is formed by bending a strip-shaped steel plate in the same direction at a right angle and then bending the strip-shaped steel plate in the opposite direction at a right angle, the part, in contact connection with the upper frame, of the upper end of the outwards-rolled bent steel plate is bent at a right angle only once, and the part, in contact connection with the lower frame, of the lower end of the outwards-rolled bent steel plate is bent at a right angle only once; the upper frame, the lower frame and the side frame are connected into an integrated counterweight housing, so that a space for accommodating a counterweight block is formed in the counterweight housing; and the counterweight block is used for being placed in the counterweight space. According to the invention, the goals of maximum cost reduction, energy conservation and emission reduction, greenness and environmental protection are achieved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator counterweight device. Background technique [0002] The elevator counterweight is also called the weight balance system, which is an important part of the elevator traction system. Its main function is to balance the weight of the car. During the operation of the elevator, the weight difference between the car and the counterweight can be kept at the same level as the traction system. Within the calculated standard, ensure that the traction drive of the elevator is normal. The counterweight of the elevator is located on the other side of the car, and is connected to the top or bottom of the car by a traction wire rope. The theoretical calculation before the counterweight optimizes the load of the elevator, so the counterweight plays an energy-saving role in the elevator traction system. [0003] my country's national standard GB / T7588.1-2020 stipulates: "5.4.11.2 ...

AI Technical Summary

Problems solved by technology

[0004] At present, there is a counterweight frame whose upper and lower frames are generally processed with 12-24mm thick plates, and the side frames are processed with 5-6mm steel plates into the shape of channel steel. Profiled channel steel is used as the counterweight frame column and upper and lower side frames, and the cost is high.

At the same time, plate bending is used as the column of the counterweight frame. During the transportation and handling of the side frame, the plate bending side frame is seriously deformed, which cannot be corrected, affects the installation accuracy, and even cannot be used.
