Machine-room-free elevator arrangement structure

Abstract

The invention provides a machine-room-free elevator arrangement structure, which comprises a lift car, a counterweight device, a traction machine and a steel wire rope, wherein the lift car, the counterweight device, the traction machine and the steel wire rope are arranged in a shaftway, the counterweight device is positioned at the back side of the lift car, a counterweight reverse rope wheel parallel to a transverse center line of the shaftway is arranged on the counterweight device, a load bearing beam parallel to the longitudinal center line direction of the shaftway is arranged above the lift car, the traction machine is arranged at the back side of the load bearing beam, a dragging wheel is parallel to the longitudinal center line of the shaftway, a lift car rope end and a counterweight rope end are also respectively arranged on the load bearing beam from the front side to the back side, two lift car reverse rope wheels are arranged on the top of the lift car from the front side to the back side, one end of the steel wire rope is fixedly arranged on the lift car rope end, the other end of the steel wire rope downwards and sequentially goes around the two lift car reverse rope wheels, upwards goes around a traction wheel, and then downwards goes around the counterweight reverse rope wheel, and finally, the end upwards extends and is fixedly arranged on the counter weight rope end. Compared with the prior art, the machine-room-free elevator arrangement structure has the advantages that the structure is simpler and neater, the shaftway space is saved, and the operation of an elevator is more stable.

Description

technical field [0001] The invention relates to an arrangement structure of an elevator, in particular to an arrangement structure of an elevator without a machine room. Background technique [0002] Machine room-less elevators have been adopted by more and more people because of their advantages of not occupying the space of the machine room, environmental protection, and energy saving. In recent years, in the Chinese market, the market share of machine-room-less elevators has shown a rapid upward trend, and the market has higher and higher requirements for the design and manufacture of machine-room-less elevators. [0003] At present, the layout structure of machine room-less elevators on the market is to install the counterweight device on the left or right side of the car, and the traction machine is installed on the load-bearing beam above the side close to the counterweight device. The bottom of the car is equipped with car anti-rope wheels along the left and right si...

AI Technical Summary

Problems solved by technology

The layout structure of the elevator without machine room in the prior art has the disadvantages of complex structure due to the use of multiple guide wheels, unstable operation of the elevator, long length of traction wire rope, and high cost

In addition, the machine room-less elevators of the prior art occupy a large space in the shaft, and the distribution of the traction machine, car rope heads and counterweight rope heads above the shaft is disorderly and untidy, which is not conducive to maintenance
