Setup structure applicable to idler wheel guide shoe of eccentric load lift car

Abstract

The invention discloses a setup structure applicable to an idler wheel guide shoe of an eccentric load lift car. Compressing idler wheels on at least one side of a lift car guide rail are installed on a guide shoe base in an eccentric mode, the wheel shaft axis of each compressing idler wheel and an installing center line of each compressing idler wheel on the guide shoe base are arranged in a spaced mode due to eccentric installation, when the compressing idler wheels rotate in an eccentric mode, the radial position of each compressing idler wheel can be adjusted, pressing force of the compressing idler wheels to the lift car guide rail can be adjusted, then balance of stress of two sides of the lift car guide rail can be adjusted, friction force between the guide shoe of the eccentric load lift car and the lift car guide rail can be greatly reduced, shock in operation of the eccentric load lift car can be reduced, and comfort of riding the eccentric load lift car can be improved. In addition, a shock absorption block can abut against the top face of the lift car guide rail, can absorb the shock in operation of the lift car, and can also improve the degree of comfort of use of the lift car. Due to the fact that the shock absorption block is arranged, installing space and cost can be reduced besides that the effect of shock absorption is achieved compared with an idler wheel mentioned in the background technology.

Description

technical field [0001] The invention relates to an arrangement structure of a roller guide shoe suitable for an eccentrically loaded car. Background technique [0002] In the existing setting structure of roller guide shoes, there are a pair of rollers arranged side by side on the guide shoe seat, and the pair of rollers press against both sides of the car guide rail. In addition, there is another roller on the guide shoe seat that presses against the car. The top surface of the guide rail, when this setting structure is applied to the backpack frame car, since the backpack frame car is an unbalanced load car, the pressing force of a pair of rollers on the car guide rail is unbalanced, and even the rollers on one side will be out of balance. If the guide rail cannot be pressed, the normal operation of the car will be affected. In addition, the top surface of the car guide rail is also pressed tightly by a roller, which requires a larger installation space. Contents of the...

[0002]In the existing setting structure of roller guide shoes, there are a pair of rollers arranged side by side on the guide shoe seat, and the pair of rollers are pressed against both sides of the car guide rail. In addition, there is a roller on the guide shoe seat that presses against the top surface of the guide rail of the car. When this setting structure is applied to the car with backpack frame, since the car with backpack frame belongs to the car with partial load, this will cause a pair of rollers to press against the car. The pressing force of the car guide rail is unbalanced, and even the rollers on one side will not be able to press the guide rail, which will affect the normal operation of the car

In addition, the top surface of the car guide rail is also pressed tightly by a roller, which requires a large installation space
