Abstract

A machine-room-less elevator counterweight traction device comprises a main frame; the bottom of the main frame is fixed with a counterweight frame which is internally provided with a counterweight iron; the main frame is provided with an appliance component, an installing cabinet of a safety device and a shaft; the right side of the main frame is provided with a driving device I which comprises a motor I, a motor II, a reducer I, a reducer II, a gas spring, a movable ejector rod, a rotating arm plate III, a rotating arm plate IV, an idler wheel I and an idler wheel II; and the left side of the main frame is symmetrically provided with a driving device II which has the same structure with the driving device I. The device causes the traction device and the counterweight to become one and can provide more available space for a hoistway.

Description

technical field [0001] The invention relates to a machine room-less elevator counterweight drive traction device. Background technique [0002] At present, the counterweight of an elevator without a machine room is mainly used to relatively balance the weight of the elevator car. The traction rope is wound on the traction sheave of the elevator. One end of the traction rope is connected to the counterweight, and the other end is connected to the elevator car. The motor drives the traction sheave, relying on the traction force generated by the friction between the traction rope and the traction sheave to realize the lifting movement of the car and the counterweight. The traction machine is generally installed on the guide rail bracket of the elevator guide system, or installed in the pit. Affected by the external dimensions of the traction machine, it takes up a large space in the hoistway. Contents of the invention [0003] The object of the present invention is to provi...
