Compact type passenger elevator counterweight device without machine room

Abstract

The compact type passenger elevator counterweight device without the machine room comprises two straight beams (1) which are distributed in parallel, lower beam plates (2) are arranged on the front sides and the rear sides of the lower ends of the straight beams (1), bent upper beam plates (3) which are matched with each other are arranged on the front sides and the rear sides of the upper ends of the straight beams (1), an inclined containing cavity is formed between the two bent upper beam plates (3), and a counterweight rope wheel assembly (4) is arranged in the inclined containing cavity; rope wheel side plates (5) connected with the bent upper beam plate (3) are arranged on the two sides of the counterweight rope wheel assembly (4). Counterweight blocks (6) stacked up and down are arranged between the two straight beams (1), and a pressing plate assembly (7) is arranged above the counterweight block (6) at the upper end. The counterweight device can be well suitable for a well with a compact size.

Description

technical field [0001] The invention relates to a counterweight device for an elevator, in particular to a compact machine room-less passenger elevator counterweight device. Background technique [0002] The elevator without machine room is relative to the elevator with machine room. It saves the machine room, and moves the control panel, traction machine, speed limiter, etc. in the original machine room to the hoistway and other places. Machine room-less passenger elevator mainly includes car, counterweight device, guide rail, traction device and other components. With the increasing shortage of land resources, the size of the shaft in the building is getting smaller and smaller; when the size of the shaft is relatively compact, if the current conventional counterweight is used, the host cannot be put down, and it will interfere with the shaft wall ; When the main engine is moved to the side of the car, the wheels of the counterweight are not in line with the wheels of the...

AI Technical Summary

Problems solved by technology

With the increasing shortage of land resources, the size of the shaft in the building is getting smaller and smaller; when the size of the shaft is relatively compact, if the current conventional counterweight is used, the host cannot be put down, and it will interfere with the shaft wall ; When the main engine is moved to the side of the car, the wheels of the counterweight are not in line with the wheels of the main engine. If there is a misalignment, the wire rope cannot be installed; if the counterweight moves to the inside like the main engine, it will be in line with car interference

Therefore, the existing technology has the problem that the conventional counterweight device cannot be applied to the hoistway with a relatively compact size.
