Problems solved by technology

However, the existing traction rope is usually a single strand, so the car running guide rail needs to be provided outside the car to prevent the car from shaking when it is running. The vertical accuracy needs to be very high to ensure that the car runs in the vertical direction. At the same time, the side of the counterweight also needs to be provided with a counterweight running guide rail to keep the counterweight running smoothly. The car running guide rail and the counterweight The setting of the heavy running guide rail not only increases the cost of the elevator, but also leads to a large occupied space in the entire elevator room

Abstract

The lift dragging and driving mechanism includes one dragging motor, one cage connected via a dragging mechanism to the dragging motor, and one output turntable connected to the rotor of the motor. The dragging mechanism includes one first dragging rope and one second dragging rope wound on the output turntable, the first fixed pulley for the first dragging rope to wind around, the second fixed pulley for the second dragging rope to wind around, and one counterweight block. One end of the first dragging rope and one end of the second dragging rope are connected symmetrically to the top of the cage for the cage to maintain balance during running, and the other end of the first dragging rope and the other end of the second dragging rope are connected to the counterweight block to avoid shaking of the counterweight block and to ensure the smooth vertical running of the cage. The present invention makes it possible to emit guide track for the cage and guide track for the counterweight block and to lower lift installing cost.

Description

technical field [0001] The invention relates to an elevator traction transmission mechanism. Background technique [0002] In the prior art, the traction transmission mechanism of the elevator includes a traction motor and a traction mechanism driven by the traction motor. The traction mechanism includes a pulley and a traction rope that goes around the pulley. The rotor of the traction motor is connected with an output turntable. The traction rope is wound on the output turntable, and the two ends of the traction rope protrude from the output turntable. One end of the traction rope is connected to the car, and the other end of the traction rope is connected to the counterweight. The traction motor After starting, the traction rope is driven to move through the output turntable to realize the lifting movement of the car, and the counterweight moves in the opposite direction to the car. However, the existing traction rope is usually a single strand, ...
