[0028] The railway turnout rail is damaged by train vibration and long-term load during use. The above reinforcing device can be used to reinforce the basic rail 1 and the point rail 2 without damage, so as to ensure the strength of the turnout rail in subsequent use and improve the train running safety. When the reinforcing device is used, the top support 8 is arranged between the basic rail 1 and the point rail 2, the two ends of the top support 8 abut against the rail waist inside the basic rail 1 and the point rail 2 respectively, and the length of the top support 8 can be adapted to the distance between the basic rail 1 and the point rail 2. The two ends of a bolt fastener 5 are respectively provided with a first clamping body 4 and a second clamping body 7, the bolt fastener 5 applies force to the first clamping body 4 and the second clamping body 7, the first clamping body 4 and the second clamping body 7 are clamped at the outside rail waist of the basic rail 1 and the point rail 2 respectively, force is applied to the basic rail 1 and the point rail 2 from the inside and the outside at the same time, the reinforcing effect of the basic rail 1 and the point rail 2 is realized, and the strength and stability of the connection between the two are improved. The combination of the bolt fastener 5, the first clamping body 4 and the second clamping body 7 can be provided with multiple, and arranged along the extension direction of the basic rail 1, so as to further improve the firmness of the reinforcement of the basic rail 1 and the point rail 2. One side surface of the second fishplate 6 matches and abuts against the rail waist outside the point rail 2, improving the firmness of the connection between the two, and the other side surface abuts against the second clamping body 7, the second fishplate 6 is abutted against the point rail 2 by the second clamping body 7, the setting of the second fishplate 6 can increase the supporting range of the point rail 2, and improve the stability of the reinforcement of the point rail 2. The second clamping body 7 abutting against the groove bottom 601 can reduce the distance between the second clamping body 7 and the point rail 2, so that the second clamping body 7 can closely abut against the edge of the rail bottom of the point rail 2 at the planing part 201, improving the stability of the connection between the second clamping body 7 and the point rail 2 at the position of the planing part 201, and further improving the stability and reliability of the reinforcement of the point rail 2.
[0029] Further improvement is that, as shown in Figure 2 , the rail waist of the basic rail 1 is provided with a first fishplate 3 between the first clamping body 4, and the number of the first fishplate 3 and the first clamping body 4 is consistent and one-to-one. One side surface of the first fishplate 3 matches and abuts against the outside rail waist of the basic rail 1, which can increase the supporting area of the basic rail 1 and improve the stability of the support of the basic rail 1. The first fishplate 3 is provided as multiple independent ones according to the number of the first clamping body 4, which can reduce the probability of mutual interference between the first fishplate 3 and other components on the basic rail 1, and facilitate the installation of the first fishplate 3.
[0030] Further improvement is that, as shown in Figure 5 and 6As shown, the first clamp body 4 and the second clamp body 7 are both provided with an opening 401, the bolt fastener 5 includes a stud 501 penetrating the two openings 401, and the end of the stud 501 is threadedly connected with a nut 502. When the first clamp body 4 and the second clamp body 7 are installed, the stud 501 is penetrated through the two openings 401, and then the nuts 502 at the two ends of the stud 501 are tightened, so as to make the first clamp body 4 and the second clamp body 7 close to each other, and clamp the outer rail waist of the base rail 1 and the nose rail 2 respectively. The first clamp body 4 and the second clamp body 7 are respectively provided with a limiting groove matched with the rail bottom of the base rail 1 and the nose rail 2, so as to realize the close fit between the clamp body and the rail, and improve the firmness of the reinforcement of the base rail 1 and the nose rail 2.
[0031] Further improvement is that, as shown in Figure 5 and 6 , the opening 401 provided on the second clamp body 7 is a waist-shaped hole. The setting of the waist-shaped hole makes the second clamp body 7 adjustable in position up and down, so as to adapt to the height difference between the base rail 1 and the nose rail 2, and improve the convenience of use of the reinforcing device.
[0032] Further improvement is that, as shown in Figure 5 and 6 , the end of the stud 501 connected with the second clamp body 7 is fixedly connected with a limiting block 503, and the side of the second clamp body 7 away from the nose rail 2 is provided with a limiting groove 402, and the limiting groove 402 and the limiting block 503 are inserted and matched. The waist-shaped hole cannot form a limit with the stud 501, so the limiting block 503 is set, which abuts against the side of the second clamp body 7 away from the nose rail 2, increases the supporting range of the second clamp body 7, and thus improves the stability of the connection between the second clamp body 7 and the nose rail 2.
[0033] Further improvement is that, as shown in Figures 4-6 , the side of the limiting block 503 close to the nose rail 2 is provided with a protruding part 504, and the protruding part 504 is located at the same horizontal height as the rail bottom of the nose rail 2. The setting of the protruding part 504 makes the stress point of the fiber block 503 on the second clamp body 7 move to a position flat with the rail bottom of the nose rail 2, so as to make the second clamp body 7 closely connected with the rail bottom of the nose rail 2, and improve the stability of the reinforcement of the second clamp body 7 to the nose rail 2.
[0034] Further improvement is that, as shown in Figure 2 , 3As shown in Figure 7, both the first fishtail plate 3 and the second fishtail plate 6 have limiting holes 602. Both the first clamping body 4 and the second clamping body 7 are detachably connected to pins 9, which are inserted into the limiting holes 602. The pins 9 and the limiting holes 602 mutually limit each other, restricting the relative position between the first fishtail plate 3 and the first clamping body 4, preventing relative displacement between them along the radial direction of the pins 9, thereby improving the stability of the connection between the first fishtail plate 3 and the base rail 1. Similarly, it can also improve the stability of the connection between the second fishtail plate 6 and the switch rail 2, thereby improving the reliability and firmness of the reinforcement device in reinforcing the base rail 1 and the switch rail 2.
[0035] Further improvements include, for example Figure 5 As shown, both the first clamping body 4 and the second clamping body 7 have mounting holes 701. One end of the pin 9 is inserted into the mounting hole 701. The side wall of the mounting hole 701 has a threaded hole along its radial direction, and a locking screw is threaded into the threaded hole. The locking screw can lock and loosen the pin 9, thereby improving the convenience of assembling and disassembling the pin 9.
