[0017] Beneficial Effects

[0018] The present invention provides a track connection device with stable connection and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The stable track connection device and its use method When a train passes through the connection between two rails at high speed and the rail bends and deforms under the action of the wheel, the rubber block first slides downward in the first slide groove to compress the second spring. The second spring is compressed downward to drive the first slider to slide downward in the first slide groove, so that the rebound block slides downward in the first slide groove to compress the third spring. At the same time, the first slider pushes the second slider to slide leftward in the second slide groove through the inclined surface at the bottom, and then pushes the third slider to move upward in the third slide groove through the inclined surface to support the elastically deformed rail. After the train passes, the rebound block is pushed by the elastic force of the third spring to restore the first slider to its initial state, and supports the bent and deformed part of the rail by extending the third slider to prevent damage caused by excessive bending of the rail. The rebound mechanism ensures that the rail can quickly return to its original position, reducing permanent damage caused by long-term deformation accumulation and extending the service life of the rail.

[0020] (2) The stable track connection device and its use method fix the two rails on the sleepers, fit the connecting plate to the rails and then move the connecting plate horizontally. When the positioning hole and the sliding hole are aligned, the positioning pin is inserted from the sliding hole into the positioning hole by the elastic force of the first spring. After the positioning is completed, the anchor plate and the sleeper are initially fixed by installing the fastening bolts and screwing them into the first threaded hole and the fourth threaded hole. Then, the locking plate is fit to the connecting plate and the locking bolts are inserted into the locking plate and screwed into the third threaded hole and the second threaded hole. The locking plate, the connecting plate and the two rails to be connected can be locked. The initial positioning is achieved by the positioning pin, and then the fastening bolts and the locking bolts are used to fix them. This not only ensures the stability of the installation and reduces the difficulty of installation, but also improves the stability of the track connection.

[0021] (3) The stable track connection device and its use method. When the wheel passes through the connection between two rails, it will impact the rails, and the rubber sheet will initially absorb the vibration energy. At the same time, the rubber block slides downward in the first slide groove to compress the second spring, effectively absorbing the vibration and impact force generated by the passing of the train, playing a shock-absorbing role and improving the comfort of the passing train.

8. A stable track connection device and a method of using the same according to claim 3, characterized in that: The locking structure (7) is composed of two locking plates (701), a locking bolt (702), a gasket (703) and a locking nut (704); the inner walls of the two locking plates (701) are fixedly connected to the inner walls of the second threaded hole (104) and the third threaded hole (203) in sequence through the locking bolt (702); the outer walls of the locking bolts (702) close to the locking plates (701) are provided with gaskets (703); and the outer walls of the locking bolts (702) are threadedly connected to the inner walls of the locking nut (704).

9. A method for using a stable track connection device and a method for using the same according to claim 1, comprising the following steps: S1: After fixing the two rails (103) on the sleeper (101), the connecting plate (201) is fitted on the rails (103) and then the connecting plate (201) is moved laterally. When the positioning hole (105) and the sliding hole (204) are aligned, the positioning pin (402) is inserted from the sliding hole (204) into the positioning hole (105) by the elastic force of the first spring (401). After the positioning is completed, the anchor plate (301) and the sleeper (101) are initially fixed by installing the fastening bolt (303) and screwing it into the first threaded hole (102) and the fourth threaded hole (302). Then, the locking plate (701) is fitted on the connecting plate (201), and the locking bolt (702) is inserted into the locking plate (701) and screwed into the third threaded hole (203) and the second threaded hole (104). The locking plate (701), the connecting plate (201) and the two rails (103) to be connected can be locked. S2: When the wheel passes through the connection between the two rails (103), it will impact the rails (103), and the rubber sheet (202) will initially absorb the vibration energy. At the same time, the rubber block (501) slides downward in the first slide groove (206) to compress the second spring (502), effectively absorbing the vibration and impact force generated by the passing of the train, thereby playing a shock-absorbing role; S3: When the train passes through the connection of two rails (103) at high speed, when the rail (103) is bent and deformed under the action of the wheel, the rubber block (501) first slides downward in the first slide groove (206) to compress the second spring (502), and the second spring (502) is compressed downward to drive the first slider (601) to slide downward in the first slide groove (206), so that the rebound block (603) slides downward in the first slide groove (206) to compress the third spring (604), and at the same time, the first slider (601) pushes the second slider (602) to slide leftward in the second slide groove (207) through the inclined surface at the bottom, and then pushes the third slider (605) to move upward in the third slide groove (208) through the inclined surface, so as to support the elastically deformed rail (103). After the train passes, the rebound block (603) is subjected to the elastic force of the third spring (604) to push the first slider (601) to return to its initial state.
