[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1: Please refer to Figures 1-4 A high-strength concrete railway sleeper includes a sleeper structure 1, an installation component 2, and a rail body 3. The installation component 2 is located on the outer wall of the sleeper structure 1, and the rail body 3 is located at the upper end of the sleeper structure 1. The position of the sleeper structure 1 is fixed by means of the installation component 2. The sleeper structure 1 includes a first sleeper 11 and a second sleeper 12, which are arranged adjacent to each other. A reinforcement member 13 is installed on the outer side of the adjacent end of the first sleeper 11 and the second sleeper 12. The reinforcement member 13 is used to connect the first sleeper 11 and the second sleeper 12, so that the connection between the first sleeper 11 and the second sleeper 12 is covered, which effectively increases the stability of the connection and prevents the connection between the first sleeper 11 and the second sleeper 12 from loosening.
[0018] Mounting component 2 includes a fixing seat 21 and a bolt 22 threaded onto the fixing seat 21. The fixing seat 21 and the bolt 22 can fix the position of the sleeper structure 1.
[0019] A positioning hole 121 is provided on the side wall of sleeper 2 12. A positioning post 111 is installed on one side of sleeper 11. The positioning post 111 and the positioning hole 121 are compatible. A mounting groove 112 is provided on the surface of sleeper 11 and sleeper 2 12. An elastic pad 113 is installed on one side of sleeper 11. The elastic pad 113 is placed at the connection between sleeper 11 and sleeper 2 12.
[0020] The reinforcement component 13 includes a connecting frame 131 and an inclined surface 132 disposed on the outer wall of the connecting frame 131. A bolt 133 is threadedly connected to the surface of the connecting frame 131. A threaded hole 135 is also provided on the surface of the bolt 133. A threaded rod 136 is rotatably connected inside the bolt 133. One end of the threaded rod 136 is connected to a rotating block 134, and the rotating block 134 is located outside the bolt 133. The connecting frame 131 is fixed to the sleeper 11 and the second sleeper 12 by means of the bolt 133. By rotating the rotating block 134, the threaded rod 136 can be rotated into the threaded hole 135, which can reinforce the position of the bolt 133 and make it difficult for the bolt 133 to rotate. Thus, the connection between the connecting frame 131 and the sleeper 11 and the second sleeper 12 can be reinforced.
[0021] The surface of the connecting frame 131 is uniformly covered with an anti-corrosion layer 137, and the bolts 133 and the rotating block 134 are also coated with the anti-corrosion layer 137, which can improve the anti-corrosion ability and extend the service life of the connecting parts.
[0022] The bottom wall of the rail body 3 is provided with a pre-embedded hole 31, and the sleeper 11 is provided with a pre-embedded bolt 32. The pre-embedded bolt 32 and the pre-embedded hole 31 are the same in shape and size. The outer side of the rail body 3 is also provided with an installation block 33, which is fixed with screws so that the rail body 3 is fixed on the sleeper structure 1.
[0023] In this embodiment: sleeper 11 and sleeper 2 12 are brought close together, and the connecting frame 131 is placed on the outside of sleeper 11. Then, the positioning pin 111 and positioning hole 121 are used to position sleeper 11 and sleeper 2 12. Then, the connecting frame 131 can be fixed on sleeper 11 and sleeper 2 12 with the help of bolt 133. Rotating the rotating block 134 can rotate the threaded rod 136 into the threaded hole 135, which can strengthen the position of bolt 133, making it less likely to rotate. This strengthens the connection between the connecting frame 131 and sleeper 11 and sleeper 2 12, enhances its anti-loosening ability, and, together with the anti-corrosion layer 137, can improve the anti-corrosion ability and extend the service life of the reinforcement 13. At the same time, an elastic gasket 113 is also provided at the connection between sleeper 11 and sleeper 2 12 to effectively increase the flexibility of the connection and reduce stress changes caused by temperature difference.
[0024] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 and Figure 4 The inclined surface 132 is inclined to facilitate the sliding of rainwater. A sealing gasket 138 is embedded in the inner wall of the connecting frame 131. A sealing ring 139 is fitted on one side of the bolt 133 and the rotating block 134. The sealing ring 139 can play a sealing role.
[0025] In this embodiment: When the connecting frame 131 is in use, the inclined surface 132 facilitates the sliding of rainwater, allowing the rainwater to stay away from the connecting frame 131. In conjunction with the sealing gasket 138, it can prevent water from entering the connecting frame 131, thereby preventing the connecting frame 131 from rusting and affecting its use. At the same time, the bolt 133 and the rotating block 134 can work with the sealing ring 139 to seal during use, resulting in good overall sealing performance.
