Problems solved by technology

[0005] Most of the existing elevator guide rails are spliced, which are transported to the construction site for splicing after being prefabricated in the factory. The wear and noise during operation are large, which not only seriously shortens the service life, but also poses a risk to personal and property safety

Embodiment 1

[0044] see Figure 1-2 , a high-stability spliced ​​guide rail for an elevator car, comprising a plurality of guide rail bodies 1, a plurality of uniformly distributed air pressure chambers are provided on the bottom wall of the guide rail body 1, and matching air pressure lubrication bags 2 are embedded in the air pressure chambers, The pneumatic lubrication bag 2 includes a positioning plate 21, an air pressure film 22 and an oil release head 23. The air pressure film 22 and the oil release head 23 are respectively connected to the two ends of the positioning plate 21. The oil release head 23 runs through the guide rail body 1 and extends to the inner surface. An air-containing gap is left between the membrane 22 and the inner wall of the air pressure cavity.

[0045] see Figure 3-4 An elastic filling body 5 is inlaid and connected between the positioning plate 21 and the air pressure film 22, and an oil release rod 3 corresponding to the positioning plate 21 is inlaid and...

Abstract

The invention discloses a high-stability spliced ​​guide rail for an elevator car, which belongs to the technical field of elevators. The invention can use the air on the surface of the guide rail body when the elevator car is running by evenly inlaying a plurality of air pressure lubricating bags on the guide rail body. Flow, based on Bernoulli's principle, it can be known that the air flow inside the air pressure lubrication bag is almost static, so it will give the air pressure lubrication bag a squeezing force on the inside, thereby forcing the compression deformation inside the air pressure lubrication bag, and releasing the magnetic lubricating particles through extrusion The lubricating oil is released in advance to the trajectory of the elevator car through the air pressure lubrication bag, which can not only make up for part of the quality error, but also reduce wear and noise, effectively protect the elevator guide shoes and guide rails, and after passing through due to air pressure The complex shape of the lubricating bag recovers the residual lubricating oil and magnetic lubricating particles, which can effectively prolong the service life of the pneumatic lubricating bag while ensuring the running quality of the guide rail.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a high-stability spliced ​​guide rail for an elevator car. Background technique [0002] Elevator guide rails are elevator components composed of steel rails and connecting plates, which are divided into car guide rails and counterweight guide rails. From the cross-sectional shape, it can be divided into three types: T-shape, L-shape and hollow. While the guide rail plays a guiding role, it also bears the impact force of the car and elevator braking, and the impact force of the safety gear during emergency braking. The magnitude of these forces is related to the load and speed of the elevator, so guide rails should be selected according to the speed and load of the elevator. It is usually called the car guide rail as the main rail, and the counterweight guide rail as the auxiliary rail. [0003] The elevator guide rail is a safe rail for the elevator to run up and down in th...
