Technical Field
[0001] The utility model relates to the technical field of tracks, in particular to a heat-resistant alloy steel thick-wall track component. Background Art
[0002] In rail transit, a significant amount of frictional heat is generated between the wheels and the tracks during operation. This problem is particularly prominent during high-speed train operation. Heat-resistant alloy steels can withstand high temperatures, effectively preventing track materials from softening and deforming at high temperatures.
[0003] However, in the prior art, during the friction process, when the surfaces of two objects contact each other and move relative to each other, friction will be generated at the contact point. If the local pressure is too large, the stress borne by the contact point will exceed the limit that the material can withstand. When the moving part moves on the track surface and the load is unevenly distributed on the contact surface, it will cause the local friction to increase, thereby increasing the wear of the track. Utility Model Content
[0004] The purpose of the utility model is to solve the problem in the prior art that the uneven distribution of load on the contact surface will lead to increased local friction and thus increased track wear, and to propose a heat-resistant alloy steel thick-walled track component.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a heat-resistant alloy steel thick-wall track assembly, comprising a fixing frame and a fixing plate, the bottom of the fixing frame is fixedly connected to the track body, the top of the inner cavity of the track body is fixedly connected to the center track, and a moving part is installed inside the track body;
[0006] The movable member includes a movable block, the bottom of the movable block is symmetrically fixedly connected to the second fixed rod, the outer surface of the second fixed rod is rotatably connected to the second roller, the centers of both sides of the movable block are fixedly connected to the first fixed rod, the outer surface of the first fixed rod is rotatably connected to the first roller, the top of the movable block is symmetrically fixedly connected to two fixed blocks, the inner side of the fixed block is fixedly connected to the mounting bracket, the inner side of the mounting bracket is rotatably connected to the third roller, a slide groove is opened in the middle of the movable block, and a protrusion is fixedly connected to the middle of the slide groove.
[0007] Preferably, the third roller abuts against the middle of the central track, and a track plate is fixedly connected to the bottom of the central track.

[0011] Preferably, a connecting rod is fixedly connected to the center of the top of the fixed plate, and the top of the connecting rod is fixedly connected to the moving block.
[0012] Preferably, a plurality of limiting rods are symmetrically fixedly connected to both sides of the top of the fixing plate, and the tops of the limiting rods overlap with the track body.
[0013] Compared with the prior art, the advantages and positive effects of the present invention are:
[0014] 1. In the present invention, the structural design of the fixed plate connection improves the stability and movement efficiency of the system during the movement of objects. The first roller moves freely inside the track body, so that the moving mechanism can flexibly respond to different operating conditions.

This design effectively prevents the moving block from getting stuck during movement, ensures the smoothness and reliability of the system, and improves operational efficiency. The setting of the limit rod further enhances the stability of the fixed plate, which not only shares part of the load and reduces the pressure of the fixed plate under high load, but also prevents the connection from falling off due to excessive load, thereby ensuring the safety and continuity of the system operation and reducing the risk of failure. In addition, the ingenious matching of the second roller and the notch at the bottom of the track body further reduces the shaking amplitude during movement, allowing the moving block to run more smoothly on the track, improving the overall stability and operational efficiency.

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Example 1: Figure 1 - Figure 4 As shown, the utility model provides a heat-resistant alloy steel thick-wall track assembly, including a fixing frame 1 and a fixing plate 4, the bottom of the fixing frame 1 is fixedly connected to a track body 2, the top of the inner cavity of the track body 2 is fixedly connected to a center track 5, and a moving part 6 is installed inside the track body 2;
[0024] The moving part 6 includes a moving block 61, the bottom of the moving block 61 is symmetrically fixedly connected to the second fixed rod 64, the outer surface of the second fixed rod 64 is rotatably connected to the second roller 641, the center of both sides of the moving block 61 is fixedly connected to the first fixed rod 62, the outer surface of the first fixed rod 62 is rotatably connected to the first roller 63, the top of the moving block 61 is symmetrically fixedly connected to two fixed blocks 65, the inner side of the fixed block 65 is fixedly connected to the mounting bracket 651, the inner side of the mounting bracket 651 is rotatably connected to the third roller 652, a slide groove 612 is opened in the middle of the moving block 61, and a protrusion 613 is fixedly connected to the middle of the slide groove 612.
[0025] The following details the specific configuration and function of this embodiment. During the process of moving objects, the structural design using the fixed plate 4 connection not only improves the stability of the system but also optimizes the movement efficiency. The first roller 63 moves freely inside the track body 2, allowing the entire movement mechanism to flexibly respond to different operating conditions. In addition, the design of the two moving parts 6 enables the system to bend adaptively to smoothly pass through the curved portion of the center track 5, which is particularly important in applications with high loads and complex paths.
[0026] To ensure the stability of the fixed plate 4 and the movable member 6 during movement, the addition of the second roller 641 plays a key role. By providing additional support and guidance, this roller reduces lateral swing during movement, thereby improving overall operational accuracy. Simultaneously, the third roller 652 inside the fixed block 65 also plays a similar stabilizing role, ensuring that the various components can maintain good docking and coordinated operation under complex motion trajectories.
[0027] The presence of the center rail 5 not only guides and limits movement, ensuring accurate trajectory of the moving block 61 during operation, but also effectively distributes the load through its large contact surface. This design significantly increases load-bearing capacity, enabling the system to maintain excellent performance even under intense use.
[0028] By increasing the contact surface, the system can significantly reduce the pressure on the contact surface when applying the same force, thereby reducing excessive wear caused by local high pressure. This design concept not only increases the service life of the components, but also reduces maintenance costs, ensuring the reliability and stability of the entire system in long-term use.
[0029] Example 2: Figure 3 and Figure 4 As shown, the third roller 652 abuts against the middle of the center track 5, and a track plate 51 is fixedly connected to the bottom of the center track 5. A groove 52 is provided on one side of the bottom of the center track 5, and the groove 52 is slidably connected to the protrusion 613. The track plate 51 is slidably connected to the slide groove 612, and the first roller 63 is positioned on the inner side of the track body 2. The second roller 641 is located at the center of the bottom of the track body 2, and the second roller 641 abuts against the track body 2. A connecting rod 611 is fixedly connected to the center of the top of the fixed plate 4, and the top of the connecting rod 611 is fixedly connected to the moving block 61. A plurality of limit rods 3 are symmetrically fixedly connected to both sides of the top of the fixed plate 4, and the top of the limit rod 3 overlaps the track body 2.
[0030] The entire embodiment achieves the effect of precisely matching the slider with the groove 52, significantly enhancing the system's guiding capabilities. The groove 52 provides a stable path for the slider, ensuring smooth movement and reducing lateral swing, thereby enhancing overall stability. This design effectively prevents the moving block 61 from getting stuck during movement, ensuring smooth and reliable operation of the system and making it more efficient.
[0031] Furthermore, the provision of limit rods 3 further enhances the stability of fixed plate 4. Not only does it share some of the load, reducing the pressure on fixed plate 4 under high loads, it also prevents the connection between fixed plate 4 and moving member 6 from becoming disconnected due to excessive load during movement. This design ensures safe and consistent operation of the system and reduces the risk of potential failures.
[0032] During the movement of the moving block 61, the clever fit of the second roller 641 and the notch at the bottom of the track body 2 further reduces the amplitude of shaking during movement. This design allows the moving block 61 to run more smoothly on the track, thereby improving the stability and operational efficiency of the entire system. Through these meticulous design considerations, the system can maintain high performance even when handling complex operations, ensuring its reliability and durability in a variety of application scenarios.
[0033] The device's usage and operating principle: During the connection between the fixed plate 4 and the moving object, the first roller 63 moves inside the track body 2. The presence of the two moving members 6 ensures that the device adapts to the curved center track 5 during movement. Simultaneously, the second roller 641 further ensures the stability of the fixed plate 4 and moving member 6 during movement. Furthermore, the third roller 652 inside the fixed block 65 enhances stability during movement.
[0034] The presence of center rail 5 helps limit the stability of moving block 61. The larger contact surface better distributes the load, thereby increasing load-bearing capacity. During friction, wear typically results from excessive localized pressure, leading to material fatigue and spalling. Increasing the contact surface reduces the pressure on the contact surface under the same applied force, thereby reducing excessive wear caused by localized high pressure.
[0035] The matching of the protrusion 613 and the groove 52 enables the groove 52 to provide better guidance, ensure smooth movement, reduce lateral swing, improve overall stability, and prevent the moving block 61 from getting stuck during movement, thereby ensuring the smoothness and reliability of the system.
[0036] The provision of the limiting rod 3 improves the stability of the fixed plate 4, not only sharing the load, but also preventing the fixed plate 4 from becoming disconnected from the moving member 6 due to excessive load during movement. When the moving block 61 moves, the second roller 641 matches the notch at the bottom of the track body 2, thereby reducing the shaking amplitude during movement.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
