Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel manufacturing technology, and more specifically to a composite wheel for a railcar. Background Technology
[0002] The high-speed and safe operation of railway trains requires a good railway infrastructure. With the increase in high-speed rail mileage, the train operation sections are longer, and there are more bridges and tunnels, making transportation along the railway inconvenient. Meanwhile, the time limit for maintenance work "windows" is shortened. In order to ensure that the inspection and maintenance of railway equipment can be completed within a limited time and to shorten the repair time after equipment failure, the railway business authorities have begun to use track trolleys that can run on the track for inspection and maintenance work, replacing the traditional manual walking operation method.
[0003] The wheels of a railcar are in constant contact with the rail surface during use, which can damage the rails. Especially when the railcar needs to carry people, tools, or large equipment, ordinary wheels can cause more serious damage to the rails, generate more noise, and create safety hazards.
[0004] Therefore, there is an urgent need for a composite wheel for track vehicles. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a composite wheel for a track vehicle, so as to solve the problems in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0007] A composite wheel for a track trolley includes a composite wheel body connected to the track trolley; the body includes a rail-pressing part located on the left side, which is cylindrical and used to conform to the rail, and a limiting part located on the right side, which is bowl-shaped and outwardly flared; an annular groove is formed on the side of the cylindrical part, and an insulating ring is provided in the groove.
[0008] To further optimize the technical solution, an installation groove for accommodating the flange is provided on the side end face of the pressure rail section.
[0009] To further optimize the technical solution, a bowl-shaped flange groove is provided on the side end face of the limiting part, and the mounting groove, flange groove and body are all coaxially arranged.
[0010] To further optimize the technical solution, the main body has a mounting hole at its center, and several bolt holes are evenly arranged around the mounting hole, with the bolt holes located on the same circle.
[0011] To further optimize the technical solution, four bolt holes are provided.
[0012] To further optimize the technical solution, the main body is made of rigid nylon through injection molding.
[0013] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0014] This utility model provides a composite wheel for a railcar. By incorporating a rail-pressing part and a limiting part, it achieves the functions of conforming to the rail and stabilizing the wheel. The insulating ring covering the wheel ensures that it does not damage the rail during operation, reduces vibration, and lowers noise. This utility model can be applied to railcars used in railway stations, workshops, and work areas, enabling the railcar to travel more conveniently and smoothly on the rails without affecting the normal transmission and operation of railway signals, thus achieving the goal of safe and efficient operation.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0020] A composite wheel for a track vehicle, combining Figures 1 to 3 As shown, it includes body 1, groove 2, flange groove 3, bolt hole 5, mounting hole 4, mounting groove 6, and insulating ring.
[0021] The composite wheel body 1 is connected to the track trolley via a flange. The body 1 is made of rigid nylon injection molding. The body 1 includes a rail-pressing part on the left and a limiting part on the right. The rail-pressing part is cylindrical and used to fit the rail. The limiting part is cup-shaped and outwardly flared. An annular groove 2 is provided on the side of the cylindrical part, and an insulating ring 7 is installed in the groove 2.
[0022] An installation groove 6 is provided on the side end face of the rail clamping section.
[0023] A bowl-shaped flange groove 3 is provided on the side end face of the limiting part to accommodate the flange, and the mounting groove 6, flange groove 3 and body 1 are all coaxially arranged.
[0024] The main body 1 has a mounting hole 4 at its center, and four bolt holes 5 are evenly arranged around the mounting hole 4, and the bolt holes 5 are located on the same circle.
[0025] In practical use, the composite wheel body 1 is connected to the rail trolley via a flange. The connecting shaft on the rail trolley passes through the mounting hole 4 and bolts pass through the bolt holes 5 to connect the flange to the composite wheel body 1. During the rail trolley's movement, the insulating ring 7 on the composite wheel's rail-pressing part is in contact with the rail, and the limiting part is locked inside the rail, ensuring that the rail trolley will not deviate during movement and has good stability. The insulating ring 7 can reduce vibration and noise during the rail trolley's movement, preventing interference with the normal transmission and operation of railway signals. The composite wheel body 1 is injection molded from hard nylon material, making it easy to install and disassemble, and has the advantages of light weight, low motion loss, and long service life. In addition, the composite wheel has the advantages of good heat resistance, good chemical resistance, good toughness, corrosion resistance, and is an environmentally friendly and recyclable material.
