Adaptive guide rail pressing plate and elevator guide rail assembly

Abstract

The invention discloses an adaptive guide rail pressing plate and an elevator guide rail assembly. The special design combination of an upper pressing plate, a lower pressing plate and fasteners meets the requirements of installation, adjustment and positioning. Surface contact is changed into point contact, and friction force is reduced. The adaptive guide rail pressing plate comprises a pressing guide plate assembly used for clamping and fixing a wing edge of a guide rail. The pressing guide plate assembly comprises an upper pressing plate, a lower pressing plate, a first bolt and a second bolt. A first through hole is formed at the inner side of one end edge of the upper pressing plate, a second through hole is formed at one side of the first through hole, and a first protruding block protrudes out of the lower surface of the other end edge of the upper pressing plate. The lower pressing plate is bent into a Z shape and comprises a first plate body, the edge of the first plate body extends and is bent to form a second plate body, the edge of a third plate body extends and is bent to form a third plate body, a third through hole is formed in the first plate body, and a fourth through hole is formed in the third plate body; and the upper pressing plate is attached to the first plate body, and the first bolt penetrates through the first through hole and the third through hole and is screwed with a first nut to be fixed.

Description

technical field [0001] The invention belongs to the technical field of elevator guide rail installation, and in particular relates to an adaptive guide rail pressing plate and an elevator guide rail assembly. Background technique [0002] At present, the pressure guide plate of the guide rail of the elevator is mostly a single sheet metal bending or casting molding. The shape and structure of the pressure guide plate are relatively fixed and cannot be adjusted according to the change of the guide rail tolerance, and the adaptability is relatively poor. Such as CN201921770052.1, a pressure guide plate of an elevator guide rail; due to the shape of the existing pressure guide plate design and the design characteristics of the fasteners, it cannot be directly installed and positioned, resulting in a long installation time and unable to guarantee the installation quality. [0003] In addition, the existing pressure guide plate is in direct contact with the wing edge of the guide...

Problems solved by technology

[0002] At present, the pressure guide plate of the guide rail of the elevator is mostly a single sheet metal bending or casting molding. The shape and structure of the pressure guide plate are relatively fixed and cannot be adjusted according to the change of the guide rail tolerance, and the adaptability is relatively poor.

Such as CN201921770052.1, a pressure guide plate of an elevator guide rail; due to the shape of the existing pressure guide plate design and the design characteristics of the fasteners, it cannot be directly installed and positioned, resulting in a long installation time and the installation quality cannot be guaranteed

[0003] In addition, the existing pressure guide plate is in direct contact with the wing edge of the guide rail, and the contact is mostly face-to-face contact, and the guide rail and the guide rail bracket are also in face-to-face direct contact; The relative movement between the guide rail and the guide rail bracket, and the relative movement between the guide rail and the pressure guide plate, at this time, there will be a large static friction force between the guide rail and the guide rail bracket, and between the guide rail and the pressure guide plate, and the generation of this friction will affect the pressure guide plate. The design of the
