Description

Sliding block assembly suitable for rail vehicle door system

Technical Field

The utility model relates to a track traffic technique, concretely relates to sliding block set spare suitable for rail vehicle door system.

Background

The roller component adopted by the existing rail vehicle door system adopts a connecting structure of a metal roller and a bearing, so that in the actual use process, dust, impurities and the like are easy to fall into the bearing to cause the failure of the bearing in the roller component, and the service life of the roller component is reduced; and the metal gyro wheel has rust and wearing and tearing problem in the course of the work, after the metal gyro wheel rusts or wears, wheel components can produce abnormal sound in the course of the work, influences the passenger and takes experience.

The roller components that adopt metal gyro wheel require highly to the guide rail material, if guide rail material intensity is lower, the guide rail can be worn and torn at the motion in-process to the metal gyro wheel, and the guide rail has the risk of inefficacy after long-time wearing and tearing, influences door system normal operating. The metal roller and the guide rail are required to be lubricated regularly by using the roller assembly, the workload of later maintenance is increased, and the operation cost is increased.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: an object of the utility model is to provide a can solve the rusty wear problem in the metal gyro wheel working process, can also realize life cycle free lubrication's slider assembly who is applicable to rail vehicle door system.

The technical scheme is as follows: the utility model comprises a mounting seat, wherein the top surface of the mounting seat is provided with a protruding part, and the center of the protruding part is provided with a first mounting hole for mounting a sliding block shaft; the bottom of the sliding block shaft is inserted into the first mounting hole, the top of the sliding block shaft is provided with a sliding block, the sliding block rotates around the sliding block shaft, and the sliding block is made of non-metal materials.

The edges and corners of the sliding block are provided with the arc chamfers, so that the sliding block component can rotate at the arc segment position of the guide rail of the sliding plug door system of the railway vehicle conveniently, and the biting abrasion of the edges of the sliding block to the guide rail can be reduced.

And a plurality of second mounting holes are formed in the top surface of the mounting seat and are used for connecting a door system.

The top surface and the bottom surface of the sliding block are both provided with gaskets, so that the anti-falling performance of the sliding block after riveting is improved, and the abrasion of a sliding block shaft to the sliding block is reduced.

The middle part of the sliding block shaft is provided with a hexagonal flat position, so that the sliding block shaft is convenient to detach and install.

The upper part of the sliding block shaft is provided with the sliding block and the gasket through a riveting structure, so that the installation is firm.

The protruding portion on the mounting seat is arranged close to the edge of the mounting seat, and therefore the second mounting hole can be provided with as much space as possible.

Has the advantages that: compared with the prior art, the technical scheme of the utility model, its beneficial effect lies in: by adopting the non-metal square sliding block to replace a metal roller, a necessary bearing in the existing metal roller assembly is removed, and the risk of bearing failure in the working process is avoided; the square sliding block is made of non-metal materials, so that the problem of rusting of the metal roller does not exist, the requirement on the performance of the guide rail material is reduced, the requirement of no lubrication in the whole life cycle can be realized, and the time and the cost of later maintenance are greatly reduced compared with the existing metal roller assembly.

Detailed Description

The technical solution of the present invention will be described in detail with reference to the following detailed description and the accompanying drawings.

As shown in fig. 1 and 2, the present invention includes a mounting seat 1, a slider shaft 2, a washer 3, and a slider 4. The top surface of the mounting seat 1 is provided with a protruding part, and the center of the protruding part is provided with a first mounting hole for mounting the sliding block shaft 2. The bottom of the slide block shaft 2 is inserted into the first mounting hole, the top of the slide block shaft 2 is provided with a slide block 4, and the slide block 4 can rotate around the slide block shaft 2 at a small angle or completely rotate freely. The sliding block 4 is made of non-metallic materials, so that the use of the existing roller bearing is eliminated, and the problem of bearing failure is avoided; by adopting the non-metallic sliding block, the requirement on the material of the guide rail matched with the non-metallic sliding block is reduced, the requirement of no lubrication in the whole life cycle is realized, and the maintenance time and the maintenance cost are saved; the shape of the sliding block 4 is not limited to square, circular or oval, the corner of the sliding block 4 is provided with an arc chamfer, and the arc chamfer is arranged to prevent the sliding block 4 in the sliding block assembly from rotating when the sliding block works in a guide rail with only straight line segments, and can reduce biting abrasion of the edge of the sliding block on the guide rail; as shown in figure 3, when the sliding block works in the guide rail simultaneously containing the arc line end, the sliding block 4 is beneficial to the rotary motion at the position of the arc line plugging section of the guide rail, and the motion resistance of the arc line section is reduced. A plurality of second mounting holes are formed in the top surface of the mounting seat 1, and the sliding block assembly is connected with a door system through the second mounting holes. 4 top surfaces of slider, bottom surface all set up packing ring 3, and the effect that sets up the packing ring is for improving the anticreep performance of riveting back slider, reduces the wearing and tearing of slider axle to the slider. The middle part of the sliding block shaft 2 is provided with a hexagonal flat position, so that the sliding block shaft 2 can be conveniently detached and installed. The upper part of the sliding block shaft 2 is provided with a sliding block 4 and a gasket 3 through a riveting structure, and the sliding block 4 can freely rotate around the sliding block shaft after the installation is finished. The sliding block component is installed on the door system and is matched with the guide rail on the door system through the square sliding block to complete work.
