Embodiment Construction

[0022] Such as figure 1 , 2, the machine-roomless elevator device of the present invention, the driving device 4 is fixed on the top of the elevator passage, and the vertical projection of the driving device 4 can partially overlap with the side wall 3 of the elevator passage, so that the area of ​​the elevator passage 1 can be saved. Rope 13 passes through the drive pulley 5 on the drive unit 4, and one end passes through the pulley 11 of the car, and is finally fixed on the top of the hoistway; the other end of the rope 13 passes through the pulley 10 of the counterweight 7, and is finally fixed on the top of the hoistway. The driving device 4 can drive the rope 13 to drive the car 6 and the counterweight 7 to go up and down in the hoistway 1 by driving the pulley 5 . Also be provided with a fixed driving device operating platform 18 in the hoistway 1, its vertical projection does not coincide with the car 6.

Abstract

The invention relates to a lift without machine room, which comprises a lift channel, wherein inside the lift channel, the lift compartment and weight are arranged along the track; said lift channel also comprises the cable to suspend said compartment and weight, a driving device for driving said cable via several pulleys, and a fixed driving device operate platform whose vertical projection is not layered with compartment. The invention has simple maintenance, high safety and low cost.

Description

technical field [0001] The present invention relates to an elevator device, more particularly, to a machine room-less elevator device. Background technique [0002] Usually, the driving device of the machine room-less elevator is arranged in the hoistway, including the pit of the hoistway, the top of the hoistway, the inner wall of the hoistway or other positions in the hoistway. In addition to being arranged in the bottom pit, these arrangements have a common problem, that is, it is impossible to implement emergency rescue quickly. Since the driving device is inside the lifting passage, it is impossible to directly reach the driving device for cranking, so other means are needed for rescue. [0003] Chinese invention patent application publication CN1394187A (disclosure date on January 29th, 2003) discloses that counterweight is divided into upper and lower parts, and the lower counterweight is unloaded during rescue to reduce counterweight side weight. There is a connect...
