Right angle opening bag rack elevator

Abstract

The invention discloses a right angle opening bag rack elevator. An upper beam in a car rack system on the elevator comprises a main upper beam and an auxiliary upper beam, wherein the auxiliary upper beam is vertically arranged in the middle of the main upper beam and towards a car; two ends of the main upper beam are respectively fixed with two vertical beams; two separately arranged car rack rope sheaves are installed along the length direction of the auxiliary upper beam; the line of centers of the two car rack rope sheaves is vertically arranged to the symmetric center line of a pair of car rack rails; a counterweight rope sheave is installed on a counterweight frame in a counterweight system; the car rack rope sheaves, the counterweight rope sheave and the axial line of a traction sheave of a tractor are vertically arranged to the symmetric center line of the pair of car rack rails; one end part of a traction rope is fixed on a shaft way through a first rope end component; after the traction rope downwards bypasses the two car rack rope sheaves, the traction rope upwards bypasses the traction sheave on the tractor, and then the traction rope downwards bypasses the counterweight rope sheave; and the other end part of the traction rope is fixed on the shaft way through a second rope end component. By arranging the two rope sheaves, the traction torque borne by the two rope sheaves through the traction rope can basically counteract in the horizontal direction with the unbalance loading torque applied by the car rack system for pressing guide shoes on the rails, thus reducing or eliminating the applied force in the horizontal direction between the guide shoes and the rails, and reducing abrasion of the guide shoes.

Description

technical field [0001] The invention relates to an elevator with backpack racks with right-angled doors. Background technique [0002] The existing knapsack frame elevator includes a knapsack car frame system, a traction machine system, a counterweight system, a guide rail system, and a traction system. The traction machine system includes a traction machine, a load-bearing beam for supporting the traction machine, and a load-bearing beam It is fixedly installed on the upper part of the hoistway of the elevator. The guide rail system includes a pair of car frame guide rails and a pair of counterweight guide rails vertically arranged in the hoistway. The traction system includes traction ropes. The counterweight, the knapsack car frame system includes the car and the car frame used to support the car. The counterweight frame is provided with counterweight guide shoes that match the counterweight guide rails. Similarly, the car frame is provided with The car frame guide shoe ...

AI Technical Summary

Problems solved by technology

On the backpack frame elevator with a rope winding ratio of 1:1, since the direction of the centerline of the car frame system deviates from the force direction of the car frame system, a large force in the horizontal direction will cause the car frame system to The shoe is pressed on the guide rail, which is easy to wear the guide shoe, especially when the car is under severe partial load, the guide shoe is severely worn, and the guide shoe needs to be replaced frequently, and the comfort of the elevator ride is poor
