[0023] 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 of 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.

[0024] See also Figure 1-Figure 5 As shown, the utility model is a rail transit maintenance structure, comprising: support plates 2 are symmetrically installed on the upper surfaces of two bottom plates 1, and screw holes 3 are symmetrically opened on one side of the support plates 2;

[0025] Among them, a bolt 4 is arranged in the middle of the screw hole 1 3 , and the bolt 4 passes through the screw hole 1 3 . A screw hole 2 5 is symmetrically opened above the screw hole 1 3 , and a bolt 2 6 is arranged above the bolt 1 4 .

[0026] More specifically, bolt 2 (6) has a longer installation stroke than bolt 1 (4).

[0027] Specifically, vertical screw holes 7 are symmetrically opened near both ends of the bottom plate 1, and a vertical bolt 8 is arranged on the inner side of each vertical screw hole 7. The vertical bolt 8 passes through the vertical screw hole 7, and the lower end of the vertical bolt 8 is provided with a thread. The vertical bolt 8 is used to pass through the vertical screw hole 7 and fix it to the sleeper, so that the railway track can be better pressed on the railway roadbed, the stability and balance are improved, the stable operation of the train is ensured, the safety hazards brought by the rail transit rails are reduced, and the economic losses caused by the damage of the rail transit rails are avoided.

[0028] Specifically, the vertical bolt 8 is located on the side closer to the nut of the bolt 1 4.

[0029] Specifically, the upper surface of the bottom plate 1 is symmetrically provided with moving blocks 9 , one side of the moving blocks 9 is symmetrically provided with limiting grooves 10 , and the bottom end of the moving blocks 9 is symmetrically installed with sliding blocks 11 .

[0030] Specifically, the moving block 9 is square in shape and the limiting groove 10 is circular. By rotating the bolt 4, the bolt 4 is passed through the screw hole 3 to abut against the limiting groove 10 on one side of the moving block 9, so that when the bolt 4 is tightened, one end of the bolt 4 pushes the moving block 9, and the moving block 9 is further pressed against the lower end of the rail 13, thereby increasing the pre-tightening force of the bolt 4 on the rail 13 through the moving block 9, preventing the vibration and impact generated when the train travels at high speed on the track of the rail 13, avoiding the longitudinal and lateral movement of the track to generate track gauge, improving stability and balance, ensuring the stable operation of the train, further reducing the safety hazards brought by the rail transit rails, and further avoiding the economic losses caused by the damage to the rail transit rails.

[0031] Specifically, the upper surface of the bottom plate 1 is symmetrically provided with a slide groove 12 , the inner side of the slide groove 12 is slidably provided with a slider 11 , and the slide groove 12 is slidably connected to the moving block 9 through the slider 11 .

[0032] Specifically, a pad 16 is provided on the upper surface of the bottom plate 1, and a rail 13 is provided on the upper surface of the pad 16. Tiles 14 are symmetrically attached to both sides of the rail 13, and a positioning groove 15 is symmetrically opened on one side of the tile 14. The pad 16 is made of rubber material and has shock absorption and low noise performance. Its main function is to buffer the vibration and impact stress generated when the train passes through the rails, and to electrically insulate the signal system, while protecting the sleepers from wear and tear, providing a flat contact surface for the rail base, thereby increasing the contact area, reducing stress and improving stability and balance, ensuring the stable operation of the train, further reducing the safety hazards brought by the rail transit rails, and further avoiding the economic losses caused by the damage of the rail transit rails.

[0033] Specifically, by rotating the bolt 26 so that the bolt 26 can pass through the screw hole 25 and abut against the positioning groove 15 on one side of the tile 14, when the bolt 26 is further tightened, the pre-tightening force of the bolt 26 on the rail 13 is increased through the tile 14, thereby preventing the rail 13 from shifting when the train runs on the track at high speed for a long time, avoiding the longitudinal and lateral movement of the track to generate track gauge, improving stability and balance, ensuring the stable operation of the train, further reducing the safety hazards brought by the rail transit rails, and further avoiding the economic losses caused by the damage of the rail transit rails.

[0034] Specifically, one end of the bolt 4 pushes the moving block 9 to tighten the lower end of the rail 13, and also pushes and fixes one end of the tile 14 to prevent the tile 14 from shifting, thereby increasing the pre-tightening force of the bolt 4 on the rail 13 through the moving block 9.

[0035] The use process of the embodiment of the utility model is as follows: by rotating the bolt 4, the bolt 4 is made to abut against the limiting groove 10 on one side of the moving block 9 through the screw hole 13, so that when the bolt 4 is tightened, one end of the bolt 4 pushes the moving block 9 to push and tighten the lower end of the rail 13, and also pushes and fixes one end of the tile 14 to prevent the tile 14 from deviating, thereby increasing the pre-tightening force of the bolt 4 on the rail 13 through the moving block 9, and by rotating the bolt 26, the bolt 26 is made to abut against the positioning groove 15 on one side of the tile 14 through the screw hole 25, so that when the bolt 26 is further tightened, the pre-tightening force of the bolt 26 on the rail 13 is increased, thereby preventing the rail 13 from deviating when the train runs on the track at high speed for a long time, avoiding the longitudinal and lateral movement of the track to produce track gauge, improving stability and balance, ensuring the stable operation of the train, further reducing the safety hazards brought by the rails of rail transit, and further avoiding the economic losses caused by the damage of the rails of rail transit.

[0036] The working principle of the utility model is as follows: by rotating the vertical bolt 8 through the vertical screw hole 7 and fixing it with the sleeper, the bolt 14 is rotated to make the bolt 14 abut against the limiting groove 10 on one side of the moving block 9 through the screw hole 13, so that when the bolt 14 is tightened, one end of the bolt 14 pushes the moving block 9 to push the lower end of the rail 13 tightly, and also pushes and fixes one end of the tile 14 to prevent the tile 14 from deflecting, thereby increasing the pre-tightening force of the bolt 14 on the rail 13 through the moving block 9, and by rotating the bolt 26 so that the bolt 26 abuts against the positioning groove 15 on one side of the tile 14 through the screw hole 25, thereby further tightening the bolt 26, thereby increasing the pre-tightening force of the bolt 26 on the rail 13 through the tile 14, preventing the rail 13 from deflecting when the train runs on the track at high speed for a long time, avoiding the longitudinal and lateral movement of the track to produce track gauge, improving stability and balance, ensuring the stable operation of the train, further reducing the safety hazards brought by the rail transit rails, and further avoiding the economic losses caused by the damage of the rail transit rails.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
