[0022] like Figures 1 to 4As shown, the anti-rollover rail fastener device of the small train of the present embodiment comprises a metal chassis 1, wherein there are a plurality of metal chassis 1, which are installed at the upper end of the sleeper. The number of metal chassis 1 is adjusted according to the total weight of the small train. When a metal chassis 1 is installed at the upper end of each sleeper, it is most stable. A rail 2 is installed at the center position of the upper end of the metal chassis 1, and the direction of the rail 2 and the direction of the metal chassis 1 are perpendicular to each other. Two mounting blocks 6 are installed at the left and right ends of the rail 2 at the upper end of the metal chassis 1 in a mirror-symmetrical manner. The mounting blocks 6 and the metal chassis 1 are in a fixed connection relationship. A mounting ring 7 is installed at the upper end of the mounting block 6, and the interior of the mounting ring 7 is a circular cavity. The end of the mounting ring 7 close to the rail 2 is installed with a The spring fragment structure 5 has two ends closely connected with the mounting block 6 and the side wall of the rail 2 respectively. The interior of the mounting ring 7 is provided with a reinforcing steel part 3, which is inserted into the interior of the mounting ring 7. One end of the reinforcing steel part 3 is in contact with the upper edge of the metal chassis 1, and the other end of the reinforcing steel part 3 is in contact with the upper end of the spring fragment structure 5. The spring fragment structure 5 is pressed by the solid reinforcing steel part 3, one end of the reinforcing steel part 3 is in contact with the metal chassis 1, and the other end is in contact with the spring fragment structure 5, so that the position of the reinforcing steel part 3 cannot move in the vertical direction, and then the spring fragment structure 5 is fixed to the side wall surface of the rail 2 to reinforce the rail 2, enhance the connection strength between the rail 2 and the metal chassis 1, and prevent the rail 2 from tipping over.

[0023] Specifically, the shrapnel structure 5 includes a fixed base 501 and a metal shrapnel 502. The lower end of the fixed base 501 is connected to the upper end of the metal chassis 1. The metal shrapnel 502 is installed at the end of the fixed base 501 close to the rail 2. The lower end of the metal shrapnel 502 contacts the side wall of the rail 2, and the upper end of the metal shrapnel 502 contacts the reinforcing steel part 3. The metal shrapnel 502 has a certain inclination angle, and the specific angle needs to be customized according to the curvature of the side wall of the rail 2 of the small train. The fixed base 501 and the metal shrapnel 502 are installed in an integrated fixed connection manner. The metal shrapnel 502 is restricted to the surface of the side wall of the rail 2 by the reinforcing steel part 3, thereby fixing the position of the rail 2.

[0024] Furthermore, the reinforcing steel component 3 includes a first extruded steel rod 301, an installation steel rod 302, a connecting steel rod 303 and a second extruded steel rod 304.

The second extruded steel rod 304 is in contact with the upper end of the metal chassis 1. The lower end of the first extruded steel rod 301 is in contact with the spring structure 5. The second extruded steel rod 304 is in contact with the upper end of the metal chassis 1, so that the reinforcing steel component 3 cannot rotate counterclockwise. The first extruded steel rod 301 is in contact with the upper end of the spring structure 5, so that the reinforcing steel component 3 cannot rotate clockwise, thereby making the reinforcing steel component 3 unable to rotate, and at the same time, the spring structure 5 can be squeezed to stabilize the position of the spring structure 5.

[0025] Furthermore, a connecting bolt 8 is threadedly connected to the upper end of the metal chassis 1 on the left and right sides of the rail 2. The connecting bolt 8 penetrates the metal chassis 1 and extends into the interior of the sleeper through the thread. The metal chassis 1 and the sleeper are connected together by the connecting bolt 8 penetrating the metal chassis 1 and extending to the interior of the sleeper. A plurality of metal chassis 1 and a plurality of sleepers are connected together and connected to the rail 2 to form a huge whole, thereby enhancing the stability of the connection.

[0026] Furthermore, a plurality of anti-vibration bolts 4 are threadedly connected to the upper end of the metal chassis 1, and the lower end of the nut of the anti-vibration bolt 4 is in contact with the upper end of the second extruded steel rod 304. By providing a plurality of anti-vibration bolts 4, the reinforced steel part 3 is squeezed from above, and the rigid connection with close contact can reduce the vibration amplitude generated by the reinforced steel part 3 and reduce the probability of the reinforced steel part 3 falling off.

[0027] Furthermore, one inner end of the two fixed bases 501 is tightly fitted with the side wall of the rail 2, and one end of the mounting block 6 is tightly fitted with the other end of the fixed base 501. A lateral force is applied to the fixed base 501 through the mounting block 6, and then a lateral force is applied to the left and right ends of the rail 2 through the two fixed bases 501, thereby enhancing the stability of the rail 2.

[0028] The method of using this embodiment is as follows: by laying multiple metal chassis 1 above the sleepers, laying the rails 2 on the upper ends of the multiple metal chassis 1, limiting the two sides of the rails 2 by the spring structure 5, and then pressing the spring structure 5 by the solid reinforcing steel part 3, one end of the reinforcing steel part 3 is in contact with the metal chassis 1, and the other end is in contact with the spring structure 5, so that the position of the reinforcing steel part 3 cannot move in the vertical direction, and then the spring structure 5 is fixed to the side wall surface of the rail 2 to reinforce the rail 2, enhance the connection strength between the rail 2 and the metal chassis 1, and avoid the rail 2 from tipping over.
