Problems solved by technology

The weight of the suspension system composed of the entire car and counterweight must be considered in the design of traditional direct drive elevators. Therefore, when designing the entire elevator drive system, if the system weight is too heavy, it will affect the design of the main shaft of the traction machine, and the system weight Too light and cannot provide enough friction to make the wire rope and the traction sheave slip

Embodiment 1

[0012] see figure 1 The shown indirect drive elevator includes a traction machine with a traction sheave 1 and a rewinding sheave 4, a counterweight 3, a car 2, and a driving wire rope 5, the traction machine being arranged in the counterweight; the upper end of the driving wire rope Fixed on the uppermost part of the hoistway, the driving wire rope passes through the traction sheave 1 in the traction machine, the driving wire rope winds out of the traction sheave and then winds into the traction sheave 1 again through the rewinding wheel 4, and then the lower end of the driving wire rope is fixed on the shaft of the hoistway the bottom. The counterweight is connected with the car by hanging wire ropes 6 . Suspension wire rope 6 passes guide wheel 7 that is installed on the mechanical beam. The rewinding wheel 4 is above the traction wheel 1 .

Embodiment 2

[0014] The difference between embodiment 2 and embodiment 1 is that the rewinding wheel 4 is below the traction wheel 1 .

[0015] The feature of the present invention is that the traction machine is assembled in the counterweight, one section of the steel wire rope is fixed on the uppermost part of the hoistway, and the other end is fixed on the lowermost part of the hoistway through the traction wheel and rewinding wheel system. Throughout the drive system, the traction machine drives the counterweight to reciprocate up and down. In addition, the car system and the counterweight system are connected by another set of suspension wire rope system through the mechanical beam and the guide wheels installed on the mechanical beam.

[0016] The invention is a gecko type indirect drive elevator. The traction machine is installed on the counterweight side of the elevator, and the traction machine reciprocates up and down along with the counterweight. The traction machine drives the...

Abstract

The invention provides an indirectly-driven elevator of which the driving force for traction is not restricted by the weight change of an elevator cabin and the distance of a wire rope suspended core. The invention is applicable to a passenger elevator, a sightseeing elevator, a medical service elevator, a freight elevator and other vertical lifting elevators. The indirectly-driven elevator comprises a traction machine, a counterweight, the elevator cabin and a driving wire rope, wherein the traction machine is arranged in the counterweight; the upper end of the driving wire rope is fixed to the uppermost part of a shaft, the driving wire rope is wound around a traction wheel of the traction machine, and the lower end of the driving wire rope is fixed to the lowermost part of the shaft.

Description

technical field [0001] The invention relates to a gecko indirect drive elevator, in particular, an indirect drive traction elevator whose traction driving force is not limited by the weight change of the car and the distance of the hanging core suspended by the wire rope. Background technique [0002] At present, the traction elevator installed in the building generally adopts the method of directly driving the car and the counterweight by hanging the car and the counterweight at both ends of the traction machine, and using the friction force between the traction wheel and the wire rope. The weight of the suspension system composed of the entire car and counterweight must be considered in the design of traditional direct drive elevators. Therefore, when designing the entire elevator drive system, if the system weight is too heavy, it will affect the design of the main shaft of the traction machine, and the system weight It is too light and cannot provide enough friction to m...
