Elevator counterweight frame assembling structure

Abstract

The invention belongs to the technical field of elevator counterweight frames, and particularly relates to an elevator counterweight frame assembling structure. The elevator counterweight frame assembling structure comprises a frame structure, counterweight block side face fixing pieces and counterweight block top face fixing pieces, the frame structure comprises a top beam, side beam assemblies are arranged on the two sides of the top beam, and a bottom beam is arranged at the bottoms of the side beam assemblies. The top beam, the side beam assemblies and the bottom beam are fastened through bolts, a rope wheel is installed in the top beam, a middle beam is fixed between the side beam assemblies, the middle beam is fixed between the top beam and the bottom beam through bolts, so that the size of a single corresponding counterweight block is reduced, workers can conveniently carry the counterweight block, the counterweight block is quickly mounted in a counterweight frame, so that the labor intensity is reduced, the carrying risk is reduced, the bearing capacity of side beams is increased, and the dangerous deformation condition of the side beams is avoided; and meanwhile, a counterweight mounting opening is sealed by using a counterweight side fixing piece, so that the stability of the counterweight block is enhanced from the side surface while the middle beam is reinforced.

Description

technical field [0001] The invention belongs to the technical field of an elevator counterweight frame, and in particular relates to an assembly structure of an elevator counterweight frame. Background technique [0002] Elevator counterweight is a method of maintaining balance between the weight of the car and the payload portion. Counterweight to reduce energy consumption and motor power loss. In addition, on hoists with rope drive pulleys, the counterweight maintains the required stress ratio between the car and the rope branches on one side of the counterweight, in order to obtain proper friction between the rope and the rope drive pulley groove force.

Problems solved by technology

[0003] In the existing elevator counterweight frame, the structure of the side beam is produced by a flat plate through punching, bending and other processes. For some relatively long counterweight frame side beams, especially the high-speed ladder type counterweight The frame side beams require a very large processing length. When installing the counterweights on the counterweight frame of such extended side beams, it is difficult to neatly install the counterweights into the bottom of the frame, making the installation of the counterweights difficult.

[0004] There are some existing counterweight frame side beam structures, which achieve quick installation of the counterweight by opening square holes on the side beam, but when the length of the counterweight frame side beam is long, although it is convenient to install the counterweight, due to the internal The added counterweight is heavy, and the gap opened by the side beam will reduce the load-bearing tension of the side beam, causing the side beam to deform at the gap, resulting in a dangerous situation
