It is usually installed between the track and the sleeper, or installed at the turning point of the track to reduce the impact force on the track when the train passes, improve the running stability of the train and the riding comfort of the passengers. Some common types of railway track shock absorbers are hydraulic shock absorbers, spring shock absorbers, rubber shock absorbers and air shock absorbers. The working principles of these shock absorbers are basically the same, which is to absorb the vibration energy during the train running and convert it into other forms of energy to reduce the vibration and noise of the track. Therefore, there is a special need for an anti-subsidence railway track shock absorber.
[0003] However, the existing anti-subsidence railway track shock absorbers generally directly use shock-absorbing springs or shock-absorbing pads to absorb and dissipate vibration energy to achieve shock absorption, and the shock absorption effect is poor.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The drainage shock-absorbing mechanism 5 includes a guide block 501, a water collecting groove 502, a shock-absorbing pad 503, a damper 504, a shock-absorbing spring 505, a drainage pipe 506, a buffer block 507, a drainage hole 508 and a buffer spring 509. The guide block 2 is embedded with the guide block 501, a water collecting groove 502 is provided on one side of the surface of the guide block 501, a shock-absorbing pad 503 is connected to the surface of the guide block 501, a damper 504 is connected to the bottom of the guide block 501, and a shock-absorbing spring is connected to the bottom of the guide block 501. 505, a drainage pipe 506 is connected to the bottom of the guide block 501, a buffer block 507 is connected to one side of the surface of the guide block 501, a drainage hole 508 is opened on one side of the surface of the guide block 501, and a buffer spring 509 is connected to one side of the surface of the buffer block 507. When the train wheels pass over the rail 3, first, part of the vibration generated during the train running will be reduced by the shock-absorbing pad 503 at the bottom of the rail 3, and then under continuous vibration, the guide block 501 continuously moves up and down and squeezes the damper 504, the damper The shock absorbing spring 505 and the buffer block 507, the shock absorbing spring 505 is constantly deformed up and down to absorb and buffer the energy of vibration, and the damper 504 consumes the energy of vibration to reduce the amplitude and duration of vibration. At the same time, the buffer block 507 is squeezed and moves to squeeze the buffer spring 509 on one side of the surface. The buffer spring 509 is squeezed and constantly deformed to further absorb and disperse energy, which effectively reduces the vibration and noise generated during the running of the train and effectively prevents the settlement of the sleeper 1. When it rains, when rainwater flows into the interior of the guide block 2 through the gap between the guide block 501 and the guide block 2, the rainwater is collected by the sump 502, and then the rainwater in the sump 502 enters the drain pipe 506 through the holes on the surface of the guide block 2, and then discharged. When the rainwater unfortunately floods the sump 502 and enters the interior of the guide block 2, the rainwater will also be discharged from the drain hole 508 in time, effectively avoiding the shock absorbing spring 505 from being corroded by rainwater for a long time, causing its aging and deformation, thereby improving the overall shock absorbing life of the product.
[0022] Furthermore, one end of the damper 504 passes through the shock-absorbing spring 505 and is connected to the inner wall of the guide block 2. The shock-absorbing spring 505 is provided with four groups, and the damper 504 is provided with four groups. Through the setting of the damper 504 and the shock-absorbing spring 505, when in use, the damper 504 can consume the energy of vibration to reduce the amplitude and duration of vibration. At the same time, the damper 504 can also reduce the excessive impact and fatigue damage of the shock-absorbing spring 505, which helps to extend the service life of the shock-absorbing spring 505. The shock-absorbing spring 505 can continuously deform to absorb and buffer the vibration energy generated during the travel of the train, thereby effectively reducing the vibration of the train and the noise generated, as well as the stability of the train during travel.
[0023] Furthermore, the guide block 501 is a porous hollow structure, and the shock-absorbing pad 503 is connected to the rail 3. Through the arrangement of the guide block 501 and the shock-absorbing pad 503, when in use, since the guide block 501 is a porous hollow structure, rainwater inside the sump 502 can quickly enter the drain pipe 506 through the holes on the surface of the guide block 501, effectively avoiding the contact between rainwater and the shock-absorbing spring 505, which causes the spring to be corroded, aged and deformed. The shock-absorbing pad 503 can effectively absorb and disperse the vibration energy of the train during operation, and effectively reduce the vibration and noise of the train.
[0024] Furthermore, two groups of buffer blocks 507 are provided, and one end of the shock-absorbing spring 505 is connected to the inner wall of the guide block 2. Through the setting of the buffer block 507, when in use, the buffer block 507 is squeezed by the guide block 501, it can move and squeeze the buffer spring 509, thereby facilitating the subsequent buffer spring 509 to further absorb the vibration energy generated during the travel of the train, thereby improving the shock-absorbing effect of the device and reducing the vibration and noise of the train.
[0025] Further, the mounting mechanism 4 includes a side cover plate 401, a support block 402, a slot 403, a limiting slot 404, a first bolt 405, an upper cover plate 406 and a second bolt 407. One side of the surface of the sleeper 1 is connected to the side cover plate 401, the inner side of the sleeper 1 is connected to the support block 402, one side of the surface of the sleeper 1 is provided with a slot 403, one side of the surface of the sleeper 1 is provided with a limiting slot 404, the surface of the side cover plate 401 is threadedly connected to the first bolt 405, the surface of the guide block 2 is connected to the upper cover plate 406, and the surface of the upper cover plate 406 is threadedly connected to the second bolt 407. The second bolt 407 is set. When in use, first, the guide block 2 is embedded into the inside of the limiting groove 404. At this time, the support block 402 supports the guide block 2. Then, one end of the side cover plate 401 is clamped into the clamping groove 403, so that the threaded holes on the surface of the side cover plate 401 are horizontally aligned with the threaded holes on one side of the surface of the sleeper 1. Then, the first bolt 405 is used to fix it. At this time, the guide block 2 is fixed to the sleeper 1. Then, the rail 3 is placed in the middle of the surface of the guide block 2, and then the upper cover plate 406 is attached to one side of the rail 3. Then, the upper cover plate 406 is adjusted so that the threaded holes on its surface are horizontally aligned with the threaded holes on the surface of the guide block 2. Then, the second bolt 407 is used to fix it. At this time, the rail 3 is fixed to the surface of the guide block 2, thereby completing the installation.

Through the setting of the side cover plate 401, when in use, the side cover plate 401 is used to limit the position of the guide block 2, and then cooperates with the first bolt 405 to effectively fix and limit the guide block 2.
[0027] Furthermore, one side of the surface of the support block 402 is in contact with the guide block 2, and the limiting groove 404 matches the size of the guide block 2. Through the setting of the support block 402, when in use, the support block 402 can provide a stable supporting force for supporting the guide block 2, thereby stabilizing the guide block 2.
[0028] Working principle: First, when installing the rail 3, fit the guide block 2 into the limit groove 404. At this time, the support block 402 supports the guide block 2. Then, one end of the side cover plate 401 is clamped into the clamping groove 403, so that the threaded hole on the surface of the side cover plate 401 is horizontally aligned with the threaded hole on one side of the surface of the sleeper 1. Then, the first bolt 405 is used to fix it. At this time, the guide block 2 is fixed to the sleeper 1. Then, the rail 3 is placed in the middle of the surface of the guide block 2, and then the upper cover plate 406 is attached to the rail. 3, and then adjust the upper cover plate 406 so that the threaded holes on its surface are horizontally aligned with the threaded holes on the surface of the guide block 2, and then use the second bolt 407 to fix it. At this time, the rail 3 is fixed to the surface of the guide block 2, so that the installation is completed. When the train wheels pass over the rail 3, first, part of the vibration generated during the train's travel will be reduced by the shock-absorbing pad 503 at the bottom of the rail 3, and then under continuous vibration, the guide block 501 continuously moves up and down and squeezes the damper 504 and the shock-absorbing spring 505. And buffer block 507, shock-absorbing spring 505 continuously deforms up and down to absorb and buffer the energy of vibration, and damper 504 consumes the energy of vibration to reduce the amplitude and duration of vibration. At the same time, buffer block 507 moves and squeezes buffer spring 509 on one side of the surface after being squeezed. Buffer spring 509 is squeezed and continuously deforms to further absorb and disperse energy, which effectively reduces the vibration and noise generated during the running of the train and effectively prevents the settlement of sleeper 1. When it rains, rainwater flows into the interior of guide block 2 through the gap between guide block 501 and guide block 2, and is collected by sump 502. Then the rainwater in sump 502 enters drain pipe 506 through the holes on the surface of guide block 2 and is then discharged. When rainwater unfortunately floods sump 502 and enters the interior of guide block 2, rainwater will also be discharged from drain hole 508 in time, effectively avoiding the problem that shock-absorbing spring 505 is corroded by rainwater for a long time, causing its aging and deformation, thereby improving the overall shock-absorbing life of the product.
