Right angle-opening cantilever elevator

Abstract

The invention discloses a right angle-opening cantilever elevator, which comprises a cantilever car frame system, a total weight system, a tractive system and a guiding system. An upper beam of the cantilever car frame system comprises a main upper beam of which the two end parts are respectively connected to two vertical beams, and an auxiliary upper beam vertically arranged in the middle of the main upper beam and facing a car; the auxiliary upper beam is provided with a car frame rope wheel; a total weight frame is provided with a total weight rope wheel; axial lead directions of the car frame rope wheel, the total weight rope wheel and a tractive wheel of a tractor are vertical to the symmetrical center line of the two vertical beams; one end part of a tractive rope is fixed to an elevator shaft, and the other end part of the tractive rope bypasses the total weight rope wheel downwards, bypasses the tractive wheel of the tractor upwards, bypasses the car frame wheel downwards, and is fixed to the elevator shaft finally to realize the two-to-one rope; and the rope wheels are arranged, so that the traction torque applied to the rope wheels through the tractive rope and the unbalanced load torque that a guide shoe is pressed to a guide rail by the car frame system are basically offset in the horizontal direction; therefore, the acting force between the guide shoe and the guide rail in the horizontal direction can be reduced and eliminated, the wear of the guide shoe is reduced, and the comfortableness of riding the elevator is improved by balancing the torque generated by the unbalanced load of the elevator.

Description

technical field [0001] The invention relates to an elevator with backpack racks with right-angled doors. Background technique [0002] Existing knapsack frame elevators include a knapsack car frame system, a counterweight system, a traction system, and a guiding system. The counterweight system includes a counterweight frame and counterweight blocks arranged in the counterweight frame. The car, the car frame used to support the car, the car frame includes two vertical beams set on one side of the car at the same time, the upper beam set between the two vertical beams and above the car, and the upper beam set between the two vertical beams The lower beam of the car, the two vertical beams are located on the other opposite sides of the car, the lower beam is equipped with a bracket, the car is placed on the bracket, the bracket is fixedly connected with the bottom plate of the car, and the upper beam is provided with A clamping part that is clamped on the roof of the car and ...

AI Technical Summary

Problems solved by technology

However, on the right-angle door-opening backpack frame elevator, since the direction of the center line of the car frame system deviates from the force direction of the car frame system, when the car frame system is raised and lowered, there will be a large force in the horizontal direction to press the guide shoe against the guide rail. In addition, the guide shoes are easy to wear, especially when the car is under severe partial load, the guide shoes are severely worn, and the guide shoes need to be replaced frequently, and the comfort of the elevator ride is poor
