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 lubricating bag 2 includes a positioning plate 21, an air pressure film 22 and an oil release head 23. The positioning plate 21 and the oil release head 23 are respectively connected to the two ends of the air pressure film 22. 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, and belongs to the technical field of elevators. According to the high-stability spliced guide rail, a plurality of air pressure lubricating bags are uniformly embedded in a guide rail body, air flow on the surface of the guide rail body during operation of the elevator car is utilized, air flow on the inner sides of the air pressure lubricating bags is almost static on the basis of a Bernoulli principle, so that extrusion force is applied to the air pressure lubricating bags from the inner side, the interiors of the air pressure lubricating bags are forced to generate compression deformation, lubricating oil containing magnetic lubricating particles is released through extrusion, the lubricating oil is released to a running track of the elevator car in advance through the air pressure lubricating bags, part of mass errors can be made up, meanwhile, abrasion and noise can be reduced, elevator guide shoes and the guide rail can be effectively protected, residual lubricating oil and the magnetic lubricating particles are recycled after passing through due to shape restoring of the air pressure lubricating bags, so that the service life of the air pressure lubricating bags can be effectively prolonged while the operation quality of the guide rail is ensured.

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...
