Elevator arrangement structure

Abstract

The invention discloses an elevator arrangement structure. The elevator arrangement structure comprises a traction machine (1), an elevator car (3), a pair of elevator car diversion sheaves (4), a counterweight (6), a counterweight diversion sheave (7), a pair of elevator car guide rails (8), a pair of counterweight guide rails (9) and a traction rope (10), wherein the elevator car diversion sheaves (4) are arranged on the left side and the right side of the elevator car (3) respectively. The pair of elevator car guide rails (8) and the pair of counterweight guide rails (9) are located on the same side of the elevator car (3). The center connecting line of the pair of elevator car guide rails (8) is parallel to the center connecting line of the pair of counterweight guide rails (9). The traction rope (10) intersects with the center connecting line of the pair of elevator car guide rails (8) on the extension line of the connecting line connecting the pair of elevator car diversion sheaves (4), so that an acute angle which is 60-90 degrees is formed. Compared with the prior art, the elevator arrangement structure is more compact, the utilization rate of the space of a shaft is increased, the elevator car operates more smoothly, and passengers can take the elevator car more comfortably.

Description

technical field [0001] The invention relates to an elevator layout structure, in particular to a machine room-less elevator layout structure with compact structure, more stable car running and higher hoistway space utilization. Background technique [0002] Due to the continuous improvement of the economic benefit requirements of modern buildings, how to arrange the cars of the same size in smaller shafts has become a research topic for elevator technicians. In the elevator layout structure currently on the market, the mainstream layout of the car guide rail and the counterweight guide rail and the existing defects are: 1. The vertical arrangement of the car guide rail and the counterweight guide rail will reduce the utilization rate of the hoistway space; 2. The car guide rail and the counterweight guide rail are arranged in parallel, but the line connecting the pair of car anti-rope pulleys on the car suspension with the traction rope is parallel to the center line of the ...

In the elevator layout structure currently on the market, the mainstream layout of the car guide rail and the counterweight guide rail and the existing defects are: 1. The vertical arrangement of the car guide rail and the counterweight guide rail will reduce the utilization rate of the hoistway space; 2. The car guide rail and the counterweight guide rail are arranged in parallel, but the line connecting the pair of car anti-rope pulleys on the car suspension with the traction rope is parallel to the center line of the pair of car guide rails. This is commonly known as backpack rack Although the utilization rate of the hoistway is high, due to the long distance between the suspension center and the center of gravity of the car, the guide shoes of the car are affected by the partial load, which leads to poor running and braking comfort of the car. And the guide shoe wears a lot, and frequent replacement requires a lot of cost
