A machine room-less right-angle door-opening elevator traction and suspension system

Abstract

The invention discloses a machine-room-less right-angle door-opening elevator traction and suspension system, comprising: a shaft, a counterweight device and a traction device, a right-angle door-opening elevator car is arranged in the shaft, and the doors of the elevator cars are respectively arranged at The two sides of the diagonal line where the guide rail of the car is located; the counterweight device includes a counterweight block and a driving device arranged on the top of the counterweight guide rail, and the counterweight device is arranged on the side wall of the hoistway and vertically There is no overlap with the elevator car; the traction device includes at least two car reversing sheaves, and the car reversing sheave is relatively arranged at the bottom of the elevator car, and the car reversing sheave The straight line and the diagonal line of the guide rail of the car form an angle and are arranged close to the counterweight device. The invention can make full use of the width and depth of the well, effectively reduce the height of the top of the well, improve the space utilization rate of the well, and reduce the civil construction cost.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a traction and suspension system for an elevator with a right-angle door opening without a machine room. Background technique [0002] At present, due to the particularity of the civil layout and orientation requirements of stacked villa-style buildings on the market, the elevator car needs to provide two-way entrance and exit areas, and set the way to open the door at a vertical 90° right angle; and the top of the well is located in the middle of the building. The height of the top will directly affect the building structure. [0003] Most of the right-angle door elevators in the prior art are designed to install the driving device directly above the car. When the car rises to the top, in order to avoid the interference between the driving device and the car, it is necessary to increase the height of the top of the well. In addition, the suspension system needs to...

Problems solved by technology

[0003] Most of the right-angle door elevators in the prior art are designed to install the driving device directly above the car. When the car rises to the top, in order to avoid the interference between the driving device and the car, it is necessary to increase the height of the top of the shaft. In addition, the hanging system needs to use the civil structure to bear the load, resulting in low utilization rate of hoistway space and high construction cost
