Description

Technical Field

[0001] The utility model relates to the technical field of insulating gauge blocks, in particular to an insulating gauge block with a buffer structure. Background Art

[0002] Insulated gauge blocks are a key component in railway track systems, primarily used to connect the rails to the substructure, adjust the track gauge, and insulate the rails from the ground. They are a crucial component of the rail fastening system, particularly in high-speed rail. They are typically produced using injection molding machines. Their primary material is nylon (PA) + glass fiber (GF), a modified reinforced nylon. This material offers high mechanical strength, heat resistance, wear resistance, and rigidity, meeting the stringent stability and safety requirements of high-speed rail.

[0003] The design of the insulated gauge block not only ensures the reliability and stability of the track, but also ensures the elasticity and rigidity of the track when the train is running at high speed, providing passengers with a more comfortable and safe riding experience. In addition, the insulated gauge block also has good insulation performance, which can effectively prevent the current from propagating through the track and ensure the electrical safety of the railway system.

[0004] However, the end faces of traditional insulating gauge blocks generally do not have a buffer structure, which not only easily causes the gauge blocks to produce impact noise during use, but also makes driving relatively uneven. To address the above problems, the inventors proposed an insulating gauge block with a buffer structure to solve the above problems. Utility Model Content

[0005] In order to solve the problem of buffering performance of insulating gauge blocks, the purpose of the utility model is to provide an insulating gauge block with a buffer structure.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: an insulating gauge block with a buffer structure, comprising a base, both ends of the top of the base are fixedly connected to L-shaped blocks, the top of the base and located between the L-shaped blocks are fixedly connected to two symmetrically distributed threaded rods, the top of the base is provided with two symmetrically distributed limit plates, the tops of the limit plates are each provided with a second through hole, the top of the threaded rod movably passes through the second through hole, the top of the limit plate and the outer side of the threaded rod are movably sleeved with a shock-absorbing spring, the outer side of the top of the threaded rod and the upper side of the shock-absorbing spring are movably sleeved with a washer, and the diameter of the second through hole is larger than the diameter of the threaded rod.

[0007] Preferably, a rubber pad is provided on the top of the base, and two symmetrically distributed through holes are opened on the rubber pad. The through holes are movably sleeved on the outside of the corresponding threaded rods, and a steel rail is placed on the top of the rubber pad.

[0008] Preferably, the sides of the limit plates that are close to each other are fixedly connected to limit blocks, and the limit blocks are in contact with the outer side of the bottom of the rail.

[0009] Preferably, a bolt is threadedly connected to the outside of the top of the threaded rod and above the washer.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. When the rail shakes left and right, the diameter of the second through hole is set to be larger than the diameter of the threaded rod, which drives one end of the limit plate to move up and down, thereby compressing the shock-absorbing spring. The elastic force of the shock-absorbing spring is used to buffer the shaking, thereby improving the smoothness of driving and the comfort of riding;

[0012] 2. By setting up rubber pads, it is convenient to cushion the vertical direction of the rails, effectively alleviate the impact of the road surface, and further improve the smoothness of driving and riding comfort. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Example: Figure 1-3 As shown, the utility model provides an insulating gauge block with a buffer structure, including a base 1, both ends of the top of the base 1 are fixedly connected with L-shaped blocks 2, the top of the base 1 and between the L-shaped blocks 2 are fixedly connected with two symmetrically distributed threaded rods 3, the top of the base 1 is provided with two symmetrically distributed limit plates 4, the top of the limit plates 4 are each provided with a through hole 2 11, the top of the threaded rod 3 movably passes through the through hole 2 11, the top of the limit plate 4 and the outer side of the threaded rod 3 are movably sleeved with a shock-absorbing spring 5, and the outer side of the top of the threaded rod 3 and the upper side of the shock-absorbing spring 5 are movably sleeved with a washer 6.

[0020] By adopting the above technical solution, when assembling the insulating gauge block in the rail fastener, the rubber pad 8 is first placed on the top of the base 1, and the threaded rod 3 is movable through the corresponding through hole 9, and then the rail 12 is placed on the top of the rubber pad 8, and the rubber pad 8 is used to buffer the vertical direction of the rail 12, effectively alleviating the impact of the road surface, improving the smoothness of driving and the comfort of riding, and then the two limiting plates 4 away from the limiting blocks 10 are respectively fitted with the inner sides of the corresponding L-shaped blocks 2, and the limiting blocks 10 are fitted with the two sides of the bottom of the rail 12, so as to locate the position of the rail 12, and then the shock-absorbing spring 5 and the washer 6 are sequentially sleeved on the outer side of the threaded rod 3, and the washer 6, the shock-absorbing spring 5 and the limiting plate 4 are limited by rotating the bolt 7 to ensure the safety of the vehicle.

[0021] A rubber pad 8 is provided at the top of the base 1 , and two symmetrically distributed through holes 9 are opened on the rubber pad 8 . The through holes 9 are movably sleeved on the outer sides of the corresponding threaded rods 3 , and a steel rail 12 is placed on the top of the rubber pad 8 .

[0022] By adopting the above technical solution and providing the rubber pad 8, the vertical direction of the rail 12 can be easily buffered, the impact of the road surface can be effectively alleviated, and the driving smoothness and riding comfort can be improved.

[0023] The limiting blocks 10 are fixedly connected to the sides of the limiting plates 4 that are close to each other, and the limiting blocks 10 are in contact with the outer side of the bottom of the rail 12 .

[0024] By adopting the above technical solution and providing the limit block 10, it is easier to fit with the rail 12, thereby ensuring stability during installation.

[0025] The diameter of the second through hole 11 is larger than the diameter of the threaded rod 3 .

[0026] By adopting the above technical solution, by setting the diameter of the second through hole 11 to be larger than the diameter of the threaded rod 3, when the rail 12 shakes left and right, a certain space is reserved for the upward and downward movement of the limit plate 4.

[0029] Working principle: When assembling the insulating gauge block in the track fastener, first place the rubber pad 8 on the top of the base 1, and let the threaded rod 3 move through the corresponding through hole 9, then place the rail 12 on the top of the rubber pad 8, and use the rubber pad 8 to cushion the vertical direction of the rail 12, effectively alleviating road impact, improving driving smoothness and riding comfort, then fit the two limiting plates 4 away from the limiting block 10 on the side corresponding to the inner side of the L-shaped block 2, and make the limiting block 10 fit on both sides of the bottom of the rail 12, so as to locate the position of the rail 12, then sequentially sleeve the shock-absorbing spring 5 and the washer 6 on the outer side of the threaded rod 3, and limit the washer 6, shock-absorbing spring 5 and limiting plate 4 by rotating the bolt 7 to ensure the stability of the structure, and adjust the elastic force of the shock-absorbing spring 5 by vertically rotating the bolt 7;

[0030] When the rail 12 shakes left and right, since the diameter of the through hole 11 is set to be larger than the diameter of the threaded rod 3, one end of the limit plate 4 is driven to move up and down, thereby compressing the shock-absorbing spring 5, and the elastic force of the shock-absorbing spring 5 is used to buffer the resulting shaking.
