Embodiment Construction

[0020] Such as figure 1 and figure 2 In the machine room-less elevator device of the present invention shown, the drive unit 4 is located in the opening 14 of the front wall 2 of the hoistway, and the elevator control unit 12 is also located in the same opening 14 . The pulley 8 above the car and the pulley 9 above the counterweight are fixed on the hoistway top. The rope 13 passes through the driving pulley 5 on the driving device 4, and one end is transmitted to the pulley 8 above the car, and then passed through the pulley 11 of the car, and finally fixed on the top of the lifting passage; the other end of the rope 13 is passed to the pulley above the counterweight 9. Transfer the counterweighted pulley 10, and finally fix it on the top of the lifting channel. 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 . The inspection door 15 is located on the side of the opening 14 n...

Abstract

The invention relates to a lift without machine room, which comprises a lift channel, a compartment, weight, several pulleys, cable and driving device, wherein said driving device is all or partly mounted inside the lift channel at the side surface of door; said driving device is horizontally projected vertical to the floor door, while said projection is not layered with opened floor door. The invention can solve the problem as the interference between the cable above driving device and the floor door. The invention has simple structure, low cost and easy maintenance.

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...
