Description

Technical Field

[0001] This invention belongs to the field of track reinforcement technology, and in particular relates to a non-destructive reinforcement device for turnout rails. Background Technology

[0002] Turnouts are important pieces of equipment on railway lines. They are used to connect two tracks running in different directions and are one of the key devices to ensure railway traffic safety.

[0003] Patent CN220468510U discloses an emergency reinforcement device for turnout rails, including a reinforcement plate connected to the outside of the stock rail and a reinforcement shoe connected to the outside of the switch rail. A clamp for use with the stock rail is provided on one side of the reinforcement plate. A first screw is threaded onto the clamp, and a second screw is threaded onto the reinforcement shoe. The ends of the first and second screws are fixedly connected. A top sleeve is also provided between the stock rail and the switch rail. The two ends of the top sleeve are respectively provided with top plates that contact the inside of the stock rail and the inside of the switch rail.

[0004] However, in reality, there are irregularly shaped rails with variable cross-sections, such as... Figure 1 As shown, the width of the rail base or rail web will change. When the switch rail and stock rail are reinforced by the above-mentioned reinforcement device, the change in the width of the rail base or rail web causes the reinforcement shoe to be unable to fit tightly with the rail base, thereby affecting the connection strength between the reinforcement device and the rail, and ultimately affecting the reinforcement effect of the reinforcement device.

[0005] Therefore, it is necessary to improve the non-destructive reinforcement devices in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a non-destructive reinforcement device for turnout rails, which improves the reinforcement effect and ease of use of the reinforcement device.

[0007] To achieve the above objectives, the specific technical solution of the turnout rail non-destructive reinforcement device of the present invention is as follows:

[0008] A non-destructive reinforcement device for turnout rails includes a top support component disposed between the main rail and the switch rail. A connecting component and a first clamp are sequentially disposed on the outer rail web of at least one of the main rail and the switch rail, and a fishplate and a second clamp are sequentially disposed on the outer rail web of the other rail. The first clamp and the second clamp are connected to each other by fasteners.

[0009] The connecting component includes several unit shims stacked sequentially along the horizontal direction towards the outside of the rail web. The thickness of the connecting component can be adjusted by increasing or decreasing the number of unit shims.

[0010] Preferably, in order to improve the stability of the connection of the connecting components at the rail web, the unit gasket includes an elastic abutment gasket and a plurality of elastic intermediate gaskets. The width of the abutment gasket is greater than the width of the rail web, and the width of the intermediate gasket is greater than or equal to the width of the rail web. A positioning pin is provided on the side of the abutment gasket adjacent to the first clamp. Each of the intermediate gaskets is provided with a positioning hole, and the positioning pin passes through the positioning hole on each of the intermediate gaskets in sequence.

[0011] Preferably, in order to improve the tightness of the intermediate gasket against the abutment gasket, multiple ribs extending along their own width direction are provided on both sides of the intermediate gasket. The width of the ribs is smaller than the width of the rail web. The ribs are evenly distributed along the length direction of the intermediate gasket, and the ribs on both sides of the intermediate gasket are staggered.

[0012] Preferably, in order to improve the overall strength of the connecting components and thus improve the stability of the reinforcement device, anti-slip pads are provided between each pair of the abutment pads and each of the intermediate pads.

[0013] Preferably, in order to ensure a tight connection between the intermediate gasket and the abutment gasket, and a tight fit between the abutment gasket and the rail web, a fastening gasket is also provided between the intermediate gasket and the first clamp. The fastening gasket has a positioning hole, and ribs are provided on both sides of the fastening gasket. The vertical cross-section of the fastening gasket is an arc-shaped structure, and the opening of the arc-shaped structure faces the rail web. Both sides of the fastening gasket are flipped to form rolled edges.

[0014] Preferably, in order to improve the clamping firmness of the first clamp and the second clamp, both the first clamp and the second clamp are provided with a rail bottom slot and a plug hole, the second clamp has an abutment part that abuts against the fishtail plate, and the first clamp is detachably connected to an abutment block that abuts against the connecting component.

[0015] Preferably, in order to adjust the height of the abutment block so that it can abut against the center position of the connecting component, both the abutment block and the first clamp are provided with mounting holes for passing through the bolt assembly, one of the mounting holes being a waist-shaped hole distributed vertically.

[0016] Preferably, in order to improve the stability of the connection between the abutment block and the first clamping body, multiple horizontally extending limiting strips are provided on the sides of the abutment block and the first clamping body that are close to each other. Each limiting strip is distributed at equal intervals in the vertical direction, and the interval between two adjacent limiting strips is equal to the width of the limiting strip.

[0017] Preferably, in order to improve the ease of connection between the first clamp and the second clamp, the fastener includes a stud that passes through the two insertion holes, a nut is threaded to one end of the stud and the nut is pressed against the second clamp, a limit block is fixedly connected to the other end of the stud and the limit block is pressed against the first clamp, and positioning grooves are provided on the opposite sides of the first clamp and the second clamp.

[0018] Preferably, in order to adjust the height difference between the first clamp and the second clamp to adapt to the height difference between the base rail and the tip rail, one of the insertion holes on the first clamp and the second clamp is a waist-shaped hole extending vertically.

[0019] The non-destructive reinforcement device for turnout rails of the present invention has the following advantages:

[0020] 1. The first clamp and the second clamp clamp the base rail and the switch rail from the outside, and the top support supports the switch rail and the base rail from the inside, which realizes the zero-time reinforcement between the base rail and the switch rail. Moreover, there is no need to drill holes in the base rail and the switch rail, which improves the convenience of using the reinforcement device.

[0021] 2. By adjusting the thickness of the connecting components, the gap between the first clamp and the base rail or switch rail can be controlled, so that the first clamp can be closer to the base rail or switch rail at the position of the bottom cut section of the rail, and the first clamp can be tightly fitted to the bottom of the rail, thereby improving the firmness of the reinforcement device for the base rail and switch rail.

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] The terms "top surface," "bottom surface," and "full surface" are used with reference to the normal operating state of the reinforcement device and are only for the purpose of describing the present invention and simplifying the description. They are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0038] Variable cross-section rails typically refer to the switch rails in railway turnouts, which are important components of the switch. The width of the rail base or the thickness of the rail web varies with the variable cross-section rail. When reinforcement devices are used to reinforce the rails, if the same fishplate is used for different widths of the rail base and different thicknesses of the rail web, the gap between the clamp and the rail will increase at the narrower rail base or the thicker rail web, resulting in a decrease in the fit between the two and thus affecting the connection strength between them. Ultimately, this affects the reinforcement effect of the reinforcement device on the turnout rails.

[0039] In response to the above problems, such as Figure 2 and 3 As shown, a non-destructive reinforcement device for turnout rails is provided, including a top support 8 disposed between the main rail 1 and the switch rail 2. A connecting component 4 and a first clamp 3 are sequentially disposed on the outer rail web of at least one of the main rail 1 and the switch rail 2, and a fishplate 7 and a second clamp 6 are sequentially disposed on the outer rail web of the other. The first clamp 3 and the second clamp 6 are connected to each other by fasteners 5. The connecting component 4 includes a number of unit shims that are sequentially stacked outward from the rail web in the horizontal direction. The thickness of the connecting component 4 can be adjusted by increasing or decreasing the number of unit shims.

[0040] In the aforementioned non-destructive reinforcement device, the connecting component 4 is located on the outer rail web of the switch rail 2. A first clamping body 3 is located on the side of the connecting component 4 away from the switch rail 2. The fishplate 7 is located on the outer rail web of the base rail 1. A second clamping body 6 is located on the side of the fishplate 7 away from the base rail 1. The first clamping body 3 and the second clamping body 6 are connected to each other by fasteners 5. By pulling the first clamping body 3 and the second clamping body 6 closer together through the fasteners 5, the base rail 1 and the switch rail 2 are clamped from the outside. A top support 8 is located between the base rail 1 and the switch rail 2 to support the base rail 1 and the switch rail 2 from the inside. Temporary reinforcement is completed between the base rail 1 and the switch rail 2; two sets of first clamp 3, second clamp 6, top support 8 and fastener 5 are provided, which can set two reinforcement points between the base rail 1 and the switch rail 2 to improve the reinforcement effect of both; two independent fishplates 7 can be set on the base rail 1 and the switch rail 2, which are respectively connected to two first clamps 3 and two second clamps 6, or the fishplate 7 can be set as a whole, with one fishplate 7 connected to two first clamps 3 or two second clamps 6. This can better adapt to the actual situation on site and improve the convenience of installing the reinforcement device.

[0041] Compared with existing turnout rail reinforcement devices, the fishtail plate 7 on the outer rail web of the fish-point rail 2 is set as the connecting component 4. By changing the number of unit shims, the thickness of the connecting component 4 can be adjusted, so that the connecting component 4 can be adapted to rail bases of different widths or rail webs of different thicknesses, achieving a tight fit between the first clamp 3 and the fish-point rail 2, improving the strength of the connection between the two, and ultimately improving the reinforcement effect of the reinforcement device on the turnout rail.

[0042] Further improvements include, for example Figure 4-6 As shown, the unit gasket includes an elastic abutment gasket 41 and multiple elastic intermediate gaskets 42. The width of the abutment gasket 41 is greater than the width of the rail web, and the width of the intermediate gaskets 42 is greater than or equal to the width of the rail web. A positioning pin 411 is provided on the side of the abutment gasket 41 adjacent to the first clamp 3. Each intermediate gasket 42 is provided with a positioning hole 421, and the positioning pin 411 passes through the positioning hole 421 on each intermediate gasket 42 in sequence.

[0043] Specifically, in this reinforcement device, the positioning pin 411 and the positioning hole 421 mutually limit each other, which can restrict the relative sliding between the abutment gasket 41 and the intermediate gasket 42, and improve the overall strength of the connecting component 4; both the abutment gasket 41 and the intermediate gasket 42 are made of spring steel, so that they will generate a certain elasticity after being compressed and deformed. In the unstressed state, the middle part of the abutment gasket 41 and the intermediate gasket 42 arches towards the rail web to form an arc-shaped structure. The arc-shaped structure can play a certain positioning role when the abutment gasket 41 and the intermediate gasket 42 are pressed into the rail web; in use, the abutment gasket 411 and the intermediate gasket 42 are pressed into the rail web. After the first clamp 3 and each intermediate shim 42 are stacked in sequence, the first clamp 3 presses against the outermost intermediate shim 42. Then, the first clamp 3 is fastened by the fastener 5, thereby squeezing the abutment shim 41 and the intermediate shim 42 into the rail web through the first clamp 3. The number of intermediate shims 42 can be changed according to the width of the bottom of the switch rail 2 and the thickness of the rail web, thereby changing the overall thickness of the abutment shim 41 and the intermediate shim 42. In this way, the distance between the first clamp 3 and the switch rail 2 can be adjusted, so that the first clamp 3 and the switch rail 2 fit tightly together, improving the firmness of the connection between the two, and thus improving the reinforcement effect of the reinforcement device on the turnout rail.

[0044] The width of the abutment pad 41 is greater than the width of the rail web. This allows the abutment pad 41 to cover a larger area of ​​the rail web after being squeezed into it, specifically including the bottom, top, and bottom inner walls of the rail web. Under the elastic force of the abutment pad 41, it exerts a certain force on both the top and bottom surfaces of the rail web, thereby improving the stability of the abutment pad 41 within the rail web and enhancing its support effect on the inner walls of the rail web, thus strengthening the switch rail 2. Simultaneously, the multiple intermediate pads 42, after being squeezed and deformed, exert their elastic force, with their top and bottom sides exerting force on the top and bottom inner walls of the rail web. The force exerted by the abutment 41 will make it more tightly pressed against the rail web, and will also make the abutment 41 more tightly fit against the inner wall of the rail web. Since both the abutment 41 and the intermediate 42 have good elasticity, they can conform to rail webs of different heights or depths through their own deformation under pressure, so that they can be connected to rails of different types. Furthermore, under the action of elasticity, the abutment 41 can fit more tightly against the rail web, improving the reinforcement effect of the turnout rail. The intermediate 42 plays a role in pressing the abutment 41, and at the same time, it is used to adjust the overall thickness of the connecting component 4 and improve the overall strength of the connecting component 4, so as to ensure the reinforcement effect of the turnout rail.

[0045] Further improvements include, for example Figure 6As shown, 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 rib 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 staggered.

[0046] 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 setting of 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. In this way, 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, rather than 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 enhance the reinforcement effect of the reinforcement device on the turnout rail. At the same time, the setting of 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 extending direction of the rail, and enhance the firmness of the connection between each intermediate gasket 42.

[0047] A further improvement is that, as Figure 4 shown, anti - slip pads 43 are provided between every two of the abutting gasket 41 and each intermediate gasket 42. Specifically, the anti - slip pad 43 is made of synthetic rubber, and a metal wire mesh is embedded inside the anti - slip pad 43 to enhance the overall strength of the anti - slip pad 43. The setting of the anti - slip pad 43 can increase the friction between two adjacent intermediate gaskets 42, and the anti - slip pad 43 can also fill the gap between two adjacent intermediate gaskets 42, enhance the firmness of the connection between each intermediate gasket 42, and further enhance the overall strength of the connecting component 4 to ensure the reinforcement effect of the reinforcement device.

[0048] 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 a positioning hole 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 side edges on both sides of the fastening gasket 44 are turned over to form curled edges 441.

[0049] In this reinforcement device, the ribs 422 and positioning holes 421 on the fastening gasket 44 function the same as those on the intermediate gasket 42. The direction of the arch in the middle of the fastening gasket 44 is opposite to that of the abutment gasket 41. This allows for greater elasticity when the fastening gasket 44 is pressed against the intermediate gasket 42, thus securing the abutment gasket 41 and each intermediate gasket 42. Furthermore, during the compression of the fastening gasket 44, when it is compressed from a bent state to a straight state, its upper and lower sides move outward, thereby securing the abutment gasket 41 and the intermediate gaskets 42 from the inside. On the upper and lower side walls of the rail web, multiple fastening shims 44 can be stacked to increase the pressure on the intermediate shim 42. The fastening shims 44 can be fully compressed to fit against the intermediate shim 42, or a certain gap can be left between the fastening shims 44 and the intermediate shim 42. When fully compressed, the fastening shims 44 can exert greater pressure on the intermediate shim 42, improving the reinforcement effect of the reinforcement device. When not fully compressed, the fastening shims 44 have a certain elastic deformation, which can play a certain buffering role.

[0050] Further improvements include, for example Figure 8-12 As shown, both the first clamp 3 and the second clamp 6 have a rail bottom slot 31 and a plug hole 34. The second clamp 6 has an abutting part 61 that abuts against the fishtail plate 7. The first clamp 3 is detachably connected to an abutting block 36 that abuts against the connecting part 4. Specifically, when using the first clamp 3 and the second clamp 6, the rail body needs to be inserted into the rail bottom groove 31. Through the mutual limiting effect between the rail bottom groove 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 insertion hole 34 is provided for fastener 5 to be inserted, so that the first clamp 3 and the second clamp 6 are clamped together by the fastener 5. The insertion hole 34 on the first clamp 3 is an oblong hole extending vertically. The oblong 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 as to adapt to the height difference between the base rail 1 and the switch rail 2, and improve the convenience of using the reinforcement device.

[0051] Further improvements include, for example Figure 11-13 As shown, both the abutment block 36 and the first clamp 3 are provided with mounting holes 33 for threading bolt assemblies, one of which is a slotted hole distributed vertically. The detachable abutment block 36 is used to abut the fastening washer 44. With the slotted mounting holes 33, the height of the abutment block 36 can be adjusted so that the abutment block 36 can be pressed against the middle position of the fastening washer 44, so that the fastening washer 44 is subjected to balanced force, improving the stability of the installation of the fastening washer 44, the intermediate washer 42 and the abutment washer 41, and ultimately improving the reinforcement effect of the reinforcement device on the turnout rail.

[0052] Further improvements include, for example Figure 11-13 As shown, multiple horizontally extending limiting strips 32 are provided on the sides of the abutment block 36 and the first clamping body 3 that are close to each other. Each limiting strip 32 is equally spaced vertically, and the gap between two adjacent limiting strips 32 is equal to the width of the limiting strip 32. The limiting strips 32 provided on the abutment block 36 and the first clamping body 3 limit each other, which can restrict the displacement of the abutment block 36 in the vertical direction, improve the firmness of the connection between the abutment block 36 and the first clamping body 3, and thus improve the clamping effect of the abutment block 36 on the fastening gasket 44.

[0053] Further improvements include, for example 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 threaded with a nut 52, which abuts against the second clamping body 6. The other end of the stud 51 is fixedly connected to a limiting block 53, which abuts against the first clamping body 3. The opposing sides of the first clamping body 3 and the second clamping body 6 are provided with positioning grooves 35. By turning the nut 52, it moves along the stud 51, thereby moving the first clamping body 3 and the second clamping body 6 closer to each other, realizing the locking operation between the main rail 1 and the switch rail 2. The mutual limiting between the limiting block 53 and the positioning groove 35 can limit the rotation of the stud 51 when the nut 52 is turned, improving the ease of use of 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 turnout rail.
