Description

Technical Field

[0001] This application relates to the technical field of high-speed trains, and in particular to a high-speed train positioning device slide rail frame. Background Technology

[0002] During the operation of high-speed trains, the positioning device slide rail frame plays a key role in the stability and safety of the train. Traditional slide rail frames often lack effective buffering and shock absorption mechanisms at high speeds, which leads to accelerated wear of components and loosening of connections, thus affecting the smoothness of train operation and positioning accuracy.

[0003] In the existing technology, although some slide rail frames adopt simple spring or rigid connection structures, their buffering effect is limited and they are difficult to adapt to the complex load changes brought about by the frequent start and stop of high-speed trains and high-speed operation. There is an urgent need for a slide rail frame with efficient buffering, automatic reset and stable connection functions to improve the overall performance of high-speed trains.

[0004] Therefore, those skilled in the art have provided a high-speed train positioning device slide rail frame to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a slide rail frame for a high-speed train positioning device.

[0006] The slide rail frame for a high-speed train positioning device provided in this application adopts the following technical solution:

[0007] A high-speed train positioning device slide rail frame includes an H-shaped strip. An installation groove is formed in the middle of the H-shaped strip. A housing is installed on the inner side of the H-shaped strip near both ends. The housing is filled with oil. A piston is slidably connected to the middle of the H-shaped strip. The piston has several through holes. Connecting rods are fixedly connected to the proximal ends of two pistons, passing through the housing. The proximal ends of the two connecting rods are fixedly connected to the same mounting block. The mounting block is installed in the installation groove. A second mounting hole is formed on the mounting block, passing through both the front and rear ends. A slider is slidably connected to the outer side of the H-shaped strip. Threaded rods are threadedly connected to the front and rear ends of the slider through the second mounting holes.

[0008] Preferably, slots are provided at both ends of the H-shaped strip and at the front and rear ends, and U-shaped blocks are installed at both ends of the H-shaped strip through the slots. A first mounting hole is provided at the upper end of both ends of the H-shaped strip, and bolts are installed at the upper and lower ends of the U-shaped blocks and threadedly connected to the first mounting hole.

[0009] Preferably, a first sealing ring is installed between the outer side of the piston and the housing, and a second sealing ring is installed between the proximal ends of the two housings and the connecting rod.

[0010] Preferably, a spring is fitted on the outer side of the connecting rod and near the mounting block.

[0011] Preferably, a circular plate is fixedly connected to the top of the slider, and a mounting rod is fixedly connected to the center of the top of the circular plate, with a rubber pad sleeved on the outer side of the mounting rod.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] 1. By combining oil flow damping with a spring reset mechanism, buffering and automatic reset functions are achieved, which significantly reduces vibration and impact during high-speed train operation, improves ride comfort and component durability. The cooperation between the piston and the through hole makes the oil flow controllable, the buffering process is smooth, and rigid collisions are avoided. At the same time, the spring design ensures that the mounting block quickly returns to its original position after being subjected to force.

[0014] 2. The device adopts a multi-seal and modular connection design, which enhances the sealing and stability of the overall structure, effectively preventing oil leakage and component loosening. The cooperation between the U-shaped block and the slider limits the range of motion and prevents derailment, while buffer elements such as rubber pads further reduce stress concentration at the connection points and extend service life.

[0020] Example 1

[0021] like Figure 1-3 As shown, this application discloses a high-speed train positioning device slide rail frame, including an H-shaped bar 1, an installation groove 6 in the middle of the H-shaped bar 1, a housing 11 installed on the inner side of the H-shaped bar 1 near both ends, the housing 11 being filled with oil 15, a piston 12 slidably connected to the middle of the H-shaped bar 1, a plurality of through holes 13 being opened on the piston 12, a connecting rod 9 being installed at the near ends of two pistons 12 respectively penetrating the housing 11, a common mounting block 7 being installed at the near ends of two connecting rods 9, the mounting block 7 being installed in the installation groove 6, a second mounting hole 8 penetrating the front and rear ends of the mounting block 7, a slider 17 being installed on the outer side of the H-shaped bar 1, and a threaded rod 18 being threadedly connected to the front and rear ends of the slider 17 through the second mounting hole 8;

[0022] When the mounting block 7 moves, it drives the connecting rod 9 and the piston 12 to move. The oil 15 in the housing 11 flows through the through hole 13 on the piston 12 to buffer the movement of the mounting block 7.

[0023] like Figure 1 As shown, slots 2 are provided at both ends of the H-shaped strip 1, near the front and rear ends. U-shaped blocks 3 are installed at both ends of the H-shaped strip 1 through the slots 2. A first mounting hole 4 is provided at the upper end of both ends of the H-shaped strip 1. Bolts 5 are installed at the upper and lower ends of the U-shaped blocks 3 and threadedly connected to the first mounting hole 4. The U-shaped blocks 3 are installed at both ends of the H-shaped strip 1 through the slots 2. The bolts 5 are used to connect the U-shaped blocks 3 to the first mounting hole 4. The U-shaped blocks 3 are installed to prevent the slider 17 from detaching from the H-shaped strip 1.

[0024] like Figure 2 , 3 As shown, a first sealing ring 14 is installed between the outer side of the piston 12 and the housing 11, and a second sealing ring 16 is installed between the proximal ends of the two housings 11 and the connecting rod 9. The sealing performance can be improved by setting the first sealing ring 14 and the second sealing ring 16.

[0025] like Figure 1 , 2 As shown, a spring 10 is fitted on the outer side of the connecting rod 9 and near the mounting block 7. The mounting block 7 can be reset by the spring 10.

[0026] like Figure 1 As shown, a circular plate 19 is fixed to the top of the slider 17, and a mounting rod 20 is fixed to the center of the top of the circular plate 19. A rubber pad 21 is sleeved on the outside of the mounting rod 20. The rubber pad 21 can provide cushioning at the connection point.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The implementation principle of the slide rail frame of the high-speed train positioning device in this application embodiment is as follows:

[0030] In use, the high-speed train positioning device slide rail frame achieves a buffering function through the mounting groove 6 in the middle of the H-shaped strip 1 and the oil 15 in the housing 11. When an external force is applied to the mounting block 7, the mounting block 7 drives the connecting rod 9 and the piston 12 to slide in the housing 11. The oil 15 flows through the through hole 13 on the piston 12, generating a damping effect, thereby buffering the movement of the mounting block 7. The spring 10 is sleeved on the outside of the connecting rod 9, which can push the mounting block 7 to reset after the force is released. The slider 17 is connected to the mounting block 7 through the threaded rod 18 and slides on the outside of the H-shaped strip 1. The U-shaped block 3 is fixed to both ends of the H-shaped strip 1 through the slot 2 and the bolt 5 to prevent the slider 17 from falling off. The first sealing ring 14 and the second sealing ring 16 ensure the sealing of the oil 15, while the rubber pad 21 at the top of the mounting rod 20 provides additional buffering at the connection point to enhance the overall stability.
