Description

Technical Field

[0001] This utility model relates to the field of high-speed train air cylinder technology, specifically a high-speed train air cylinder that is easy to maintain and repair. Background Technology

[0002] As the core device for air source storage in key components such as the braking system of high-speed trains, the stable operation of the air cylinder plays a decisive role in the safe operation of high-speed trains. In the daily operation and maintenance of high-speed trains, the air cylinder needs to undergo comprehensive maintenance and upkeep regularly to ensure that key performance indicators such as airtightness and structural strength always meet safety standards.

[0003] In the prior art, Chinese patent application number CN202221451898.0 discloses a train air cylinder assembly that is easy to maintain and repair. It includes a fixed horizontal plate, a fixed hanging rod, an arc-shaped clamp plate, a transverse positioning rod, an outer high-strength nut, an outer annular push plate, and a positioning seat. Fixed hanging rods are symmetrically welded to the front and rear sides of the lower end face of the fixed hanging plate. Positioning seats are symmetrically welded to the left and right sides of the lower end face of the fixed hanging plate. Arc-shaped clamp plates are symmetrically installed on the left and right sides of the annular side of the train air cylinder body. Fixed horizontal plates are symmetrically welded to the front and rear ends of the arc-shaped clamp plates. Transverse positioning rods are symmetrically inserted into the front and rear sides of the arc-shaped clamp plates. An outer high-strength nut is provided on the left side of the annular side of the transverse positioning rod. An outer annular push plate is fitted on the left side of the annular side of the transverse positioning rod. This design solves the problem of inconvenient disassembly and maintenance of the original train air cylinder, making disassembly and assembly easier and more convenient for maintenance, thus enhancing its practicality.

[0004] Based on the above information, it can be seen that the existing technology requires the use of an external wrench to rotate eight sets of high-strength self-locking nuts counterclockwise to remove the two sets of arc-shaped clamps before the main body of the air cylinder can be disassembled and maintained. The disassembly and assembly process is cumbersome and inconvenient for the disassembly, repair and maintenance of the main body of the air cylinder. Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to provide a train air cylinder that is easy to maintain and repair, in order to solve the problem mentioned in the background art that when maintaining and repairing the air cylinder body, it is necessary to use an external wrench to rotate eight sets of high-strength self-locking nuts counterclockwise to remove them before the two sets of arc-shaped clamps can be pulled down and removed, and finally the air cylinder body can be disassembled and repaired. The disassembly and assembly process is relatively cumbersome and inconvenient for the disassembly, repair and maintenance of the air cylinder body.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed train air cylinder that is easy to maintain and repair, comprising an air cylinder body, a fixed hanging plate fixedly installed on the top of the air cylinder body and fixedly installed on the bottom of the high-speed train, a first mounting plate and a second mounting plate fixedly installed on the bottom of the fixed hanging plate, and a limiting mechanism for disassembling and assembling the air cylinder body provided at the bottom of the fixed hanging plate;

[0007] The limiting mechanism includes a rotating disk rotatably mounted on the outer wall of the first mounting plate, and a rotating block rotatably mounted on the outer wall of the rotating disk. A limiting rod is rotatably mounted on the outer wall of the first mounting plate, and a limiting clamping block is rotatably mounted at the end of the limiting rod. A fixing block is rotatably mounted on the outer wall of the first mounting plate, and an adjusting rod is rotatably mounted on the outer wall of the fixing block. An adjusting block that is rotatably connected to the rotating disk is threaded onto the outer wall of the adjusting rod. A limiting plate is fixedly mounted on the outer wall of the air cylinder body. The outer walls of both the first and second mounting plates have mounting grooves corresponding to the air cylinder body. The outer wall of the second mounting plate is provided with a guiding mechanism.

[0008] Furthermore, the rotating disk is designed as a ring, and the inner diameter of the rotating disk is larger than the outer diameter of the air cylinder body. The limiting plate is designed as a ring, and the outer diameter of the limiting plate is smaller than the inner diameter of the rotating disk.

[0009] Furthermore, multiple sets of limiting rods are provided at equal angles on the outer wall of the rotating disk, and the rotating block is provided on the inner wall of the rotating disk corresponding to the limiting rods. The outer wall of the rotating block is provided with a through groove for the limiting rods to slide, and the outer wall of the limiting rods is in contact with the inner wall of the rotating block.

[0010] Furthermore, the limiting clamp is designed as a roller, and the outer wall of the limiting clamp is in contact with the outer wall of the air cylinder body, and the side wall of the limiting clamp is in contact with the outer wall of the limiting plate.

[0011] Furthermore, the outer wall of the adjusting rod is provided with a thread for adjusting the adjusting block, and the outer wall of the adjusting block is provided with a threaded through hole corresponding to the adjusting rod, and the length of the adjusting rod is set to correspond to the adjustment range of the adjusting block.

[0012] Furthermore, the guiding mechanism includes a guide plate fixedly installed on the outer wall of the air cylinder body, and a guide block is fixedly installed on the outer wall of the guide plate. The outer wall of the first mounting plate is provided with a guide groove and a slot corresponding to the guide plate and the guide block.

[0013] Furthermore, the guide plate has a circular cross-section, and the outer diameter of the guide plate corresponds to the outer diameter of the limiting plate, and the outer wall of the guide plate fits against the outer wall of the guide groove.

[0014] Furthermore, the guide block is cylindrical in shape, and the corners of the guide block end are beveled. Multiple sets of guide blocks are arranged at equal angles on the outer wall of the guide plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This easy-to-maintain train air cylinder, through a limiting mechanism, only requires turning the crank handle to rotate the adjusting rod, causing the adjusting block to move on the adjusting rod, which in turn pushes the rotating disk to rotate. When the rotating disk rotates, it drives the rotating block connected to it to move, causing the limiting rod to rotate around its rotation point with the first mounting plate as an axis. The limiting clamp block randomly controls the clamping or releasing of the air cylinder body. When installing the air cylinder body, the limiting clamp block can be quickly adjusted to the appropriate position to clamp the limiting plate on the outer wall of the air cylinder body. When disassembling, the limiting can be easily released by turning the crank handle in the opposite direction. Unlike the traditional method, there is no need to use a wrench to remove many nuts, which greatly shortens the disassembly and assembly time of the air cylinder body and significantly improves the maintenance efficiency.

[0017] Furthermore, the guide mechanism greatly optimizes the installation process of the air cylinder body. During installation, the guide plate and guide block on the outer wall of the air cylinder body can be precisely embedded into the guide groove and slot on the outer wall of the first mounting plate. The circular design of the guide plate and the characteristics of the guide blocks being distributed at equal angles on their outer walls and having beveled ends enable the air cylinder body to automatically center and smoothly slide into the installation position during installation, avoiding installation deviations, improving the accuracy and stability of installation, further saving installation time, and improving maintenance efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1-6 This utility model provides the following technical solution: a maintenance-friendly air cylinder for a high-speed train, comprising an air cylinder body 1, a fixed hanging plate 2 fixedly installed on the top of the air cylinder body 1 and fixedly mounted on the bottom of the high-speed train, a first mounting plate 3 and a second mounting plate 4 fixedly installed on the bottom of the fixed hanging plate 2, a limiting mechanism for disassembling and assembling the air cylinder body 1 provided at the bottom of the fixed hanging plate 2, the limiting mechanism including a rotating disk 5 rotatably mounted on the outer wall of the first mounting plate 3, a rotating block 501 rotatably mounted on the outer wall of the rotating disk 5, a limiting rod 502 rotatably mounted on the outer wall of the first mounting plate 3 and slidably connected to the rotating block 501, a limiting clamp 503 rotatably mounted at the end of the limiting rod 502, a fixing block 601 rotatably mounted on the outer wall of the first mounting plate 3, an adjusting rod 6 rotatably mounted on the outer wall of the fixing block 601, an adjusting block 602 rotatably connected to the rotating disk 5 threadedly mounted on the outer wall of the adjusting rod 6, a crank 603 fixedly mounted at the end of the adjusting rod 6, a limiting plate 103 fixedly mounted on the outer wall of the air cylinder body 1, and the first mounting plate 502 rotatably mounted on the outer wall of the first mounting plate 3. Both the outer walls of the 3rd and 4th mounting plates have mounting grooves 7 corresponding to the air cylinder body 1. The rotating disk 5 is designed as a ring, and its inner diameter is larger than the outer diameter of the air cylinder body 1. The limiting plate 103 has a ring-shaped cross-section, and its outer diameter is smaller than the inner diameter of the rotating disk 5. Multiple sets of limiting rods 502 are set at equal angles on the outer wall of the rotating disk 5. The rotating block 501 is set on the inner wall of the rotating disk 5 corresponding to the limiting rods 502, and the outer wall of the rotating block 501 has a passage for the limiting rods 502 to slide. The groove is formed, and the outer wall of the limiting rod 502 is in contact with the inner wall of the rotating block 501. The limiting clamp 503 is designed as a roller, and the outer wall of the limiting clamp 503 is in contact with the outer wall of the air cylinder body 1. The side wall of the limiting clamp 503 is in contact with the outer wall of the limiting plate 103. The outer wall of the adjusting rod 6 is provided with a thread for adjusting the adjusting block 602, and the outer wall of the adjusting block 602 is provided with a threaded through hole corresponding to the adjusting rod 6. The length of the adjusting rod 6 is set to correspond to the adjustment range of the adjusting block 602.

[0027] During installation, first slide the air cylinder body 1 along the mounting groove 7 on the outer wall of the first mounting plate 3 until it is in contact with the second mounting plate 4 at the end. Turn the crank handle 603 to drive the adjusting rod 6 to rotate, causing the adjusting block 602 to move on the adjusting rod 6, which in turn pushes the rotating disk 5 to rotate. When the rotating disk 5 rotates, it drives the rotating block 501 connected to it to move, so that the limiting rod 502 rotates around its rotation point with the first mounting plate 3.

The cross section of the guide plate 101 is circular, and the outer diameter of the guide plate 101 is corresponding to the outer diameter of the limiting plate 103.

[0029] During installation, the guide plate 101 and guide block 102 on the outer wall of the air cylinder body 1 can be precisely embedded into the guide groove 401 and slot 402 on the outer wall of the first mounting plate 3. The circular design of the guide plate 101 and the characteristics of the guide block 102 being distributed at equal angles on its outer wall and having beveled corners at its ends enable the air cylinder body 1 to automatically center and smoothly slide into the installation position during installation, avoiding installation deviation, improving the accuracy and stability of installation, further saving installation time, and improving maintenance efficiency.
