Figure 1 Only a part is drawn for illustration, a slot 201 is provided at the top of the sleeper body 101, a bolt 502 is fixedly connected to the inner wall of the slot 201, a card plate 501 is provided inside the slot 201, a movable hole is provided at the top of the card plate 501, the outer wall of the bolt 502 is movably interlaced with the inner wall of the movable hole, a nut 503 is sleeved on the outer thread of the bolt 502, a gasket 504 is sleeved on the outer wall of the bolt 502, and the gasket 504 is arranged between the nut 503 and the card plate 501, and the interior of the sleeper body 101 is provided with Strengthen the mechanism, after placing the rail body 102 in the slot 201, pick up the card plate 501, align the movable hole on the card plate 501 with the bolt 502, and insert the bolt 502 into the movable hole, then move the card plate 501 downward, so that the card plate 501 abuts against the rail body 102, at this time, the gasket 504 can be first sleeved on the outer wall of the bolt 502, and then the nut 503 can be screwed on the outer wall of the bolt 502 until the nut 503 tightly abuts against the gasket 504, and the installation of the rail body 102 on the sleeper body 101 can be completed.

[0020] Among them, the reinforcement mechanism includes a plurality of reinforcing ribs 601, and the plurality of reinforcing ribs 601 are all interspersed and arranged inside the sleeper body 101. The plurality of reinforcing ribs 601 are all steel bars. The reinforcing ribs 601 made of steel bars are inserted into the sleeper body 101, so that the sleeper body 101 will not be deformed when subjected to greater pressure, thereby improving the anti-deformation ability of the sleeper body 101 and extending the service life of the sleeper body 101.

[0021] In a preferred embodiment, an auxiliary mechanism is arranged between the sleeper body 101 and the rail body 102, and is used to support the rail body 102. The auxiliary mechanism includes an extended support plate 202, and a positioning mechanism is arranged between the support plate 202 and the slot 201. The length of the support plate 202 is at least twice the thickness of the sleeper body 101. The rail body 102 is arranged at the top of the support plate 202. Before the rail body 102 is placed in the slot 201, the support plate 202 needs to be stuck in the slot 201 first, and then the rail body 102 is placed on the top of the support plate 202 for installation. The extended support plate 202 increases the support area of ​​the sleeper body 101, so that when the train runs on the rail, the stress transmitted downward through the rail can be better dispersed, avoiding the sleeper body 101 from being squeezed by concentrated stress, thereby improving the load-bearing performance of the sleeper body 101.

[0022] Among them, the positioning mechanism includes a plurality of positioning blocks 301 fixedly connected to the inner wall of the card slot 201, which are used to prevent the support plate 202 from moving laterally.

[0023] Furthermore, the limiting mechanism includes a limiting plate 401 symmetrically fixedly connected to the bottom end of the support plate 202, the sleeper body 101 is interspersed between the two limiting plates 401, and a reinforcement mechanism is arranged between the limiting plate 401 and the support plate 202, the two limiting plates 401 are arranged to be extended relative to the positioning block 301, and at the same time, the distance between the two limiting plates 401 matches the thickness of the sleeper body 101, so that after the bottom end of the support plate 202 is in contact with the inner wall of the slot 201, the support plate 202 will not shake when subjected to lateral force, thereby further improving the stability of the support plate 202 in use, so that when the support plate 202 is stuck in the slot 201 and the rail body 102 is placed, the support plate 202 will not move due to the sudden contact between the rail body 102 and the support plate 202, thereby ensuring the stability of the support plate 202 in use and improving the stability of the installation of the rail body 102 and the sleeper body 101.

[0024] Furthermore, the reinforcement mechanism includes a reinforcement plate 402, one side of which is fixedly connected to the bottom of the limit plate 401, and the other side of the reinforcement plate 402 is fixedly connected to the bottom end of the support plate 202. The limit plate 401 and the support plate 202 are connected again through the reinforcement plate 402, thereby increasing the connection strength between the support plate 202 and the limit plate 401. At the same time, when the support plate 202 is subjected to the downward extrusion force of the rail body 102, the side of the support plate 202 can be supported by the reinforcement plate 402, thereby avoiding serious deformation of the two sides of the support plate 202, thereby improving the stability of the support plate 202 and further ensuring the load-bearing performance of the sleeper body 101.

[0025] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
