[0019] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] The terms "top surface", "bottom surface" and "underside" are used with reference to the normal use state of the reinforcement device, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] Variable-section rails usually refer to the pointed rails in railway turnouts and are important components in switches. The width of the rail base or the thickness of the rail waist of the variable-section rails will change. When using a reinforcement device to reinforce the rails, for rail bases of different widths and rail waists of different thicknesses, if the same fishtail plate is used, the distance between the clamp and the rail will increase at the narrower rail base or thicker rail waist, resulting in a decrease in the fit between the two, thereby affecting the connection strength between the two and ultimately affecting the reinforcement effect of the reinforcement device on the turnout rails.

[0022] In response to the above problems, Figure 2 and 3 As shown, a non-destructive reinforcement device for a turnout rail is provided, comprising a top support member 8 arranged between a stock rail 1 and a point rail 2, a connecting member 4 and a first clamp 3 being sequentially provided at the outer rail waist of at least one of the stock rail 1 and the point rail 2, and a fishplate 7 and a second clamp 6 being sequentially provided at the outer rail waist of the other, the first clamp 3 and the second clamp 6 being interconnected by a fastener 5; the connecting member 4 comprises a plurality of unit spacers sequentially stacked in a horizontal direction toward the outside of the rail waist, and the thickness of the connecting member 4 is adjusted by increasing or decreasing the number of unit spacers.

[0023] In the above-mentioned non-destructive reinforcement device, the connecting component 4 is arranged at the outer rail waist of the point rail 2, the first clamp 3 is arranged on the side of the connecting component 4 away from the point rail 2, the fish plate 7 is arranged at the outer rail waist of the stock rail 1, and the second clamp 6 is arranged on the side of the fish plate 7 away from the stock rail 1; the first clamp 3 and the second clamp 6 are connected to each other by a fastener 5, and the first clamp 3 and the second clamp 6 are pulled closer to each other by the fastener 5 to clamp the stock rail 1 and the point rail 2 from the outside, and a supporting member 8 is arranged between the stock rail 1 and the point rail 2 to support the stock rail 1 and the point rail 2 from the inside, so that Complete the temporary reinforcement between the base rail 1 and the point rail 2; the first clamp 3, the second clamp 6, the top support 8 and the fastener 5 are provided in two groups, and two reinforcement points can be set between the base rail 1 and the point rail 2 to improve the reinforcement effect of the two; the fishplate 7 on the base rail 1 and the point rail 2 can be provided with two independent ones, respectively connected to the two first clamps 3 and the two second clamps 6, or the fishplate 7 can be provided as a whole, and one fishplate 7 is connected to the two first clamps 3 or the two second clamps 6, so that it can better adapt to the actual situation on site and improve the convenience of installation of the reinforcement device.

[0024] Compared with the existing reinforcement device of the switch rail, the fishtail plate 7 at the outer waist of the fish point rail 2 is set as the connecting component 4. By changing the number of unit gaskets, the thickness of the connecting component 4 can be adjusted, so that the connecting component 4 can adapt to rail bottoms of different widths or rail waists of different thicknesses, thereby achieving a close fit between the first clamp 3 and the point rail 2, improving the firmness of the connection between the two, and ultimately improving the reinforcement effect of the reinforcement device on the switch rail.

[0025] Further improvements are, Figure 4-6 As shown, the unit gasket includes an elastic abutting gasket 41 and multiple elastic intermediate gaskets 42. The width of the abutting gasket 41 is greater than the width of the rail waist, and the width of the intermediate gasket 42 is greater than or equal to the width of the rail waist. A positioning pin 411 is provided on the side of the abutting gasket 41 adjacent to the first clamp, and each intermediate gasket 42 is provided with a positioning hole 421. The positioning pin 411 passes through the positioning holes 421 on each intermediate gasket 42 in sequence.

[0026] Specifically, in this reinforcement device, a mutual limit is formed between the positioning pin 411 and the positioning hole 421, which can limit the relative sliding between the abutting gasket 41 and the intermediate gasket 42, thereby improving the overall strength of the connecting component 4; the abutting gasket 41 and the intermediate gasket 42 are both made of spring steel, so that after being squeezed and deformed, they will generate a certain elastic force. When they are not under force, the middle parts of the abutting gasket 41 and the intermediate gasket 42 are arched toward the rail waist to form an arc-shaped structure. The arrangement of the arc-shaped structure can play a certain positioning role when the abutting gasket 41 and the intermediate gasket 42 are squeezed into the interior of the rail waist; when in use, the abutting gasket 41 and the intermediate gasket 42 are pressed into the rail waist. After the first clamp 3 and the intermediate gaskets 42 are stacked in sequence, the first clamp 3 is made to press against the outermost intermediate gasket 42, and then the first clamp 3 is fastened by the fastener 5, so that the abutting gasket 41 and the intermediate gasket 42 are squeezed into the rail waist through the first clamp 3; the number of the intermediate gaskets 42 can be changed according to the width of the bottom of the point rail 2 and the thickness of the rail waist, thereby changing the overall thickness of the abutting gasket 41 and the intermediate gasket 42, so that the distance between the first clamp 3 and the point rail 2 can be adjusted, so that the first clamp 3 and the point rail 2 are closely fitted, thereby improving the firmness of the connection between the two, and thereby improving the reinforcement effect of the reinforcement device on the switch rail.

[0027] The width of the abutment gasket 41 is set to be larger than the width of the rail waist, so that after the abutment gasket 41 is squeezed into the rail waist, the abutment gasket 41 can cover more area inside the rail waist, specifically including the bottom, top and inner wall of the rail waist. In this way, under the action of the elastic force of the abutment gasket 41, a certain force can be exerted on the top and bottom surfaces of the rail waist, thereby improving the stability of the abutment gasket 41 inside the rail waist, that is, improving the supporting effect of the abutment gasket 41 on the inner walls of the rail waist at various locations, and improving the reinforcement effect of the abutment gasket 41 on the point rail 2; at the same time, after the multiple intermediate gaskets 42 are squeezed and deformed, their top and bottom sides will exert force on the top and bottom inner walls of the rail waist under the action of their elastic force. The force acts to press the abutting gasket 41 more tightly against the rail waist and make the abutting gasket 41 fit more closely with the inner walls of the rail waist. Since the abutting gasket 41 and the intermediate gasket 42 have good elasticity, they can fit with rail waists of different heights or depths through their own deformation under pressure, so that they can be connected to rails of different types. And under the action of elastic force, the abutting gasket 41 can fit more closely with the rail waist, thereby improving the reinforcement effect of the turnout rail. The intermediate gasket 42 plays a role in tightening the abutting gasket 41 and is also used to adjust the overall thickness of the connecting component 4 and improve the overall strength of the connecting component 4 to ensure the reinforcement effect of the turnout rail.

[0028] Further improvements are, Figure 6As shown in the figure, multiple ribs 422 extending along the width direction of the intermediate gasket 42 are provided on both sides of the intermediate gasket 42. The width of the ribs 422 is smaller than the width of the rail web. The ribs 422 are equally spaced along the length direction of the intermediate gasket 42, and the ribs 422 on both sides of the intermediate gasket 42 are staggeredly distributed.

[0029] Since the rail web of the switch rail 2 is not an arc structure and its bottom surface is an approximately flat structure, in this reinforcement device, the ribs 422 can be used to enhance the strength of the intermediate gasket 42 within the range where the intermediate gasket 42 is provided with ribs 422 and limit its bending. By setting ribs 422 with different lengths, the bending limit range can be made close to the range of the bottom surface of the rail web. After the intermediate gasket 42 is squeezed into the rail web, the abutting gasket 41 and the intermediate gasket 42 can form a "C" - shaped structure that only bends on the upper and lower sides instead of an arc - shaped structure. In this way, the abutting gasket 41 and the intermediate gasket 42 can better fit the rail web and better limit the up - and - down shaking of the abutting gasket 41 and the intermediate gasket 42 within the rail web, so as to improve the reinforcement effect of the reinforcement device on the turnout rail. At the same time, the ribs 422 can also limit the position between two adjacent intermediate gaskets 42 to reduce the relative sliding between the two intermediate gaskets 42 along the rail extension direction and enhance the firmness of the connection between the intermediate gaskets 42.

[0030] A further improvement is that, as Figure 4 shown, anti - slip pads 43 are provided between the abutting gasket 41 and each intermediate gasket 42. Specifically, the anti - slip pads 43 are made of synthetic rubber, and a metal wire mesh is embedded inside the anti - slip pads 43 to enhance the overall strength of the anti - slip pads 43. The anti - slip pads 43 can increase the friction between two adjacent intermediate gaskets 42, and the anti - slip pads 43 can also fill the gap between two adjacent intermediate gaskets 42, enhance the firmness of the connection between the intermediate gaskets 42, and further enhance the overall strength of the connecting component 4 to ensure the reinforcement effect of the reinforcement device.

[0031] A further improvement is that, as Figure 4 and 7 shown, a fastening gasket 44 is further provided between the intermediate gasket 42 and the first clamp body 3. The fastening gasket 44 is provided with positioning holes 421. Ribs 422 are provided on both sides of the fastening gasket 44. The vertical cross - section of the fastening gasket 44 is an arc structure, and the opening of the arc structure faces the rail web. The two side edges of the fastening gasket 44 are turned over to form curling parts 441.

[0032] In this reinforcement device, the functions of the ribs 422 and the positioning holes 421 provided on the fastening gasket 44 are consistent with those on the intermediate gasket 42. The direction of the arch of the middle part of the fastening gasket 44 is opposite to that of the abutting gasket 41. In this way, after it is pressed against the intermediate gasket 42, a greater elastic force can be generated to press the abutting gasket 41 and each intermediate gasket 42 tightly. In addition, in the process of squeezing the fastening gasket 44, when the fastening gasket 44 is squeezed from a bent state to a straight state, its upper and lower side edges will move outward, thereby pressing the abutting gasket 41 and the intermediate gasket 42 tightly from the inside. On the upper and lower side walls of the rail waist, of course, multiple fastening gaskets 44 can also be overlapped to increase the pressure on the middle gasket 42; and the fastening gasket 44 can be selected to be completely compressed so that it fits with the middle gasket 42, or a certain gap can be left between the fastening gasket 44 and the middle gasket 42. When fully compressed, the fastening gasket 44 can exert greater pressure on the middle gasket 42, thereby improving the reinforcement effect of the reinforcement device; when not fully compressed, the fastening gasket 44 retains a certain amount of elastic deformation, so that it can play a certain buffering role.

[0033] Further improvements are, Figure 8-12 As shown, the first clamp body 3 and the second clamp body 6 are both provided with a rail bottom slot 31 and an insertion hole 34, the second clamp body 6 has an abutment portion 61 pressed against the fishtail plate 7, and the first clamp body 3 is detachably connected with an abutment block 36 pressed against the connecting component 4. Specifically, when the first clamp 3 and the second clamp 6 are in use, the rail body needs to be clamped into the inside of the rail bottom slot 31. Through the mutual limiting effect between the rail bottom slot 31 and the rail bottom, the firmness of the connection between the first clamp 3 and the second clamp 6 and the rail is improved, thereby improving the reinforcement effect of the reinforcement device on the rail; the plug-in hole 34 is used to pass the fastener 5, so that the first clamp 3 and the second clamp 6 are clamped to each other through the fastener 5; the plug-in hole 34 on the first clamp 3 is a waist-shaped hole extending vertically. The setting of the waist-shaped hole allows the first clamp 3 to move vertically, which is used to adjust the height difference between the first clamp 3 and the second clamp 6, so that it can adapt to the height difference between the basic rail 1 and the point rail 2, thereby improving the convenience of using the reinforcement device.

[0034] Further improvements are, Figure 11-13 As shown, both the abutment block 36 and the first clamping body 3 are provided with mounting holes 33 for receiving bolt assemblies, one of which is a waist-shaped hole distributed vertically. The detachable abutment block 36 is used to abut the fastening gasket 44. In conjunction with the waist-shaped mounting hole 33, the height of the abutment block 36 can be adjusted so that the abutment block 36 can abut the middle position of the fastening gasket 44, thereby balancing the force on the fastening gasket 44 and improving the installation stability of the fastening gasket 44, the intermediate gasket 42, and the abutment gasket 41, ultimately enhancing the reinforcement effect of the reinforcement device on the switch rail.

[0035] Further improvements are, Figure 11-13 As shown, the side surfaces of the abutment block 36 and the first clamping body 3 adjacent to each other are each provided with a plurality of horizontally extending limit bars 32. The limit bars 32 are evenly spaced vertically, and the interval between two adjacent limit bars 32 is equal to the width of the limit bar 32. The limit bars 32 provided on the abutment block 36 and the first clamping body 3 limit each other, thereby limiting the vertical displacement of the abutment block 36, improving the firmness of the connection between the abutment block 36 and the first clamping body 3, and thereby enhancing the abutment block 36's tightening effect on the fastening gasket 44.

[0036] Further improvements are, Figure 9-11 As shown, the fastener 5 includes a stud 51 that passes through two insertion holes 34. One end of the stud 51 is threadedly connected to a nut 52, which is set against the second clamp 6. The other end of the stud 51 is fixedly connected to a limit block 53, which is set against the first clamp 3. The first clamp 3 and the second clamp 6 are both provided with positioning grooves 35 on the opposite sides. By turning the nut 52 to move it along the stud 51, the first clamp 3 and the second clamp 6 move closer to each other, achieving the locking operation between the base rail 1 and the point rail 2. The mutual restriction between the limit block 53 and the positioning groove 35 can limit the rotation of the stud 51 when the nut 52 is turned, thereby improving the convenience of using the fastener 5; at the same time, it can also improve the stability of the connection between the various components of the reinforcement device and improve the reinforcement effect of the reinforcement device on the switch rail.
