Description

Technical Field

[0001] The utility model belongs to the technical field of rails, and in particular relates to a clamp for reinforcing rails. Background Art

[0002] Rails are the primary components of railway tracks. Their function is to guide the wheels of rolling stock, bearing the immense pressure exerted by the wheels and transmitting it to the sleepers. Rails must provide a continuous, smooth, and minimally resistant rolling surface for the wheels. On electrified railways or in automatic block sections, rails also serve as track circuits.

[0003] Currently, rails are typically assembled by attaching multiple rails together, for example, by welding. Typically, two rails are welded together using thermite welding to create a seamless track. However, due to the relatively weak welds in thermite welding process, the welds between rails are prone to breaking during heavy-load operation.

[0004] Traditionally, in order to improve the structural strength of the rails at the welded joints between rails, a clamping plate is generally added to the rail waist, and then brackets are added on both sides of the rails. The clamping plate is tightened by tightening bolts screwed on the brackets.

[0005] The existing technology has the following deficiencies:

[0006] At present, the clamping plates are only tightened by tightening bolts, but the clamping force is unstable and decays quickly, which greatly reduces the effect of reinforcing damaged rails. Utility Model Content

[0007] In view of this, the utility model provides a clamp for reinforcing rails to solve the problem in the prior art that the clamping plate is only tightened by tightening bolts, the clamping force is unstable and decays quickly, and the reinforcement effect of damaged rails is greatly reduced.

[0008] The technical solutions adopted in this utility model are as follows:

[0009] A clamp for reinforcing a rail includes a bottom plate located at the bottom of the rail. Both ends of the bottom plate are provided with vertical plates, the vertical plates are inclined from bottom to top in a direction close to the rail, and the bottom plate and the vertical plates are both made of elastic material.

[0010] In this technical solution, it should be noted that reinforcing ribs are provided at the ends of the vertical plate and the bottom plate to increase the strength of the clamp. The two vertical plates are respectively located on the left and right sides of the rail. Tightening bolts can be screwed onto the vertical plates. By screwing the tightening bolts, the clamps on both sides of the rail are tightened. The clamps are made of 40Cr steel or other high-quality alloy steels with better performance than 40Cr steel, and are manufactured using a forging process. In areas where the ambient temperature is -40℃ and below, 42CrMo or better alloy steel should be used; the contact surface between the splint and the rail should be free of rust, smooth, burr-free, oil-free, and moisture-free; in this solution, since the base plate and the vertical plate are both made of elastic materials, when the vertical plate is deformed, for example, when the vertical plate is deformed outward, it will have an elastic force toward the inside. Based on this, this solution uses the elasticity of the vertical plate to increase the fixing effect of the clamping bolt on the splint. The specific principle is: in the initial state, the two vertical plates are located on both sides of the rail, and the two vertical plates are inclined toward the direction close to the rail. When the splints on both sides of the rail are to be clamped, the clamping bolts on the vertical plates are tightened so that the ends of the clamping bolts gradually approach the splints. When the clamping bolts contact the splints, continue to tighten the clamping bolts. At this time, the vertical plates will be pushed outward by the clamping bolts, thereby causing the vertical plates to undergo elastic deformation and provide elastic force toward the splint, so that the fixing effect of the splint is better.

[0011] Preferably, a threaded sleeve is provided on the top of the vertical plate and is threadably matched with the tightening bolt.

[0012] In this technical solution, it should be noted that the threaded sleeve is a cylindrical structure with threads on its inner wall for cooperating with the threads of the tightening bolt, and the threaded sleeve is perpendicular to the splint.

[0013] Preferably, a limiting sleeve is provided at the end of the threaded sleeve, the limiting sleeve is coaxial with the threaded sleeve, a slot is penetrated through the side wall of the limiting sleeve, and the slot is arranged along the axial direction of the limiting sleeve.

[0014] In this technical solution, it should be noted that although the method of tightening the splint to the rail by means of a tightening bolt is convenient for operation, the rail is in a vibrating state for a long time (the rail will be driven to vibrate when the vehicle is running), and the tightening bolt may become loose, resulting in poor reinforcement effect of the splint on the rail. Based on this, in this solution, a slot is provided, and a socket can be provided at a position corresponding to the slot of the tightening bolt. After the tightening bolt tightens the splint, the staff inserts the pin into the slot and the socket, so that the slot limits the pin, thereby preventing the tightening bolt from rotating in the circumferential direction, thereby improving the reinforcement effect of the splint.

[0015] Preferably, there are a plurality of slots, and the plurality of slots are arranged at equal intervals along the circumference of the limiting sleeve.

[0016] In this technical solution, it should be noted that the tightening bolt is provided with holes corresponding to the number of slots, and the stability of the tightening bolt is further increased by providing multiple slots and holes.

[0017] Preferably, the vertical plate and the bottom plate are integrally formed.

[0018] In this technical solution, it should be noted that the vertical plate and the bottom plate are integrally formed to increase the rigidity of the entire device.

[0019] Preferably, the connection between the vertical plate and the bottom plate is an arc-shaped structure.

[0020] In this technical solution, it should be noted that by providing an arc structure between the vertical plate and the bottom plate, the structure between the vertical plate and the bottom plate is strengthened, and compared with a right-angle connection, it is less likely to break.

[0021] Preferably, reinforcing ribs are provided between the vertical plate and the bottom plate, and the reinforcing ribs connect the vertical plate and the bottom plate.

[0022] In this technical solution, it should be noted that the stiffness between the vertical plate and the bottom plate is further increased by providing reinforcing ribs.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, the elasticity of the vertical plates is used to enhance the fixing effect of the clamping bolts on the clamping plates. The specific principle is as follows: in the initial state, the two vertical plates are located on both sides of the rail, and both vertical plates are inclined toward the rail. When the clamping plates on both sides of the rail are to be clamped, the clamping bolts on the vertical plates are tightened so that the ends of the clamping bolts gradually move closer to the clamping plates. When the clamping bolts contact the clamping plates, the tightening bolts are further tightened. At this time, the vertical plates are pushed outward by the clamping bolts, thereby causing the vertical plates to undergo elastic deformation and provide elastic force toward the clamping plates, thereby improving the fixing effect of the clamping plates.

[0025] 2. In the present invention, a slot is provided on the limiting sleeve, and a socket can be provided at a position of the tightening bolt corresponding to the slot. When the tightening bolt tightens the splint, the staff inserts the pin into the slot and the socket, so that the slot limits the pin, thereby preventing the tightening bolt from rotating in the circumferential direction, thereby improving the reinforcement effect of the splint.

[0037] Example

[0038] like Figure 1-Figure 3 As shown, the embodiment of the present invention discloses a clamp for reinforcing a rail, comprising a base plate 1 located at the bottom of a rail 10, with vertical plates 2 provided at both ends of the base plate 1, the vertical plates 2 being inclined from bottom to top in a direction close to the rail 10, and the base plate 1 and the vertical plates 2 being made of elastic material. It should be noted that reinforcing ribs are provided at the ends of the vertical plates 2 and the base plate 1 to increase the strength of the clamp, the two vertical plates 2 being located on the left and right sides of the rail 10, respectively, and tightening bolts 8 being screwed onto the vertical plates 2, and tightening bolts 8 being screwed to tighten the clamps 11 on both sides of the rail 10, the clamps 11 being made of 40Cr steel or other high-quality alloy steels having better performance than 40Cr steel, and being manufactured using a forging process. In areas where the ambient temperature is -40°C or below, 42CrMo or better alloy steel should be used; the contact surface between the splint 11 and the rail 10 should be free of rust, smooth, burr-free, oil-free, and moisture-free; in this solution, since the bottom plate 1 and the vertical plate 2 are both made of elastic materials, when the vertical plate 2 is deformed, for example, when the vertical plate 2 is deformed outward, it will have an elastic force inward. Based on this, this solution uses the elasticity of the vertical plate 2 to increase the fixing effect of the tightening bolt 8 on the splint 11. The specific principle is: in the initial state, the two The vertical plates 2 are located on both sides of the rail 10, and the two vertical plates 2 are inclined toward the direction close to the rail 10. When the clamps 11 on both sides of the rail 10 are to be clamped, the tightening bolts 8 on the vertical plates 2 are screwed so that the ends of the tightening bolts 8 gradually approach the clamps 11. When the tightening bolts 8 come into contact with the clamps 11, the tightening bolts 8 are continued to be screwed. At this time, the vertical plates 2 will be pushed outward by the tightening bolts 8, thereby causing the vertical plates 2 to undergo elastic deformation and provide elastic force toward the clamps 11, so that the fixing effect of the clamps 11 is better.

[0039] like Figure 1 As shown, in this embodiment, the top of the vertical plate 2 is provided with a threaded sleeve 3 that is threadedly engaged with the tightening bolt 8. It should be noted that the threaded sleeve 3 is a cylindrical structure with a thread on its inner wall for threaded engagement with the tightening bolt 8. The threaded sleeve 3 is perpendicular to the clamping plate 11.

[0040] like Figure 1As shown, in this embodiment, a limiting sleeve 4 is provided at the end of the threaded sleeve 3, and the limiting sleeve 4 is coaxial with the threaded sleeve 3. A slot 5 is provided on the side wall of the limiting sleeve 4, and the slot 5 is arranged along the axial direction of the limiting sleeve 4. It should be noted that although the method of tightening the clamping plate 11 to the rail 10 by the tightening bolt 8 is convenient for operation, the rail 10 is in a vibrating state for a long time (the vehicle will drive the rail 10 to vibrate when running), and the tightening bolt 8 may become loose, resulting in a poor reinforcement effect of the clamping plate 11 on the rail 10. Based on this, in this solution, a slot 5 is provided, and a socket 9 can be provided at a position corresponding to the slot 5 of the tightening bolt 8. After the tightening bolt 8 tightens the clamping plate 11, the staff inserts the pin into the slot 5 and the socket 9, so that the slot 5 limits the pin, thereby preventing the tightening bolt 8 from rotating in the circumferential direction and improving the reinforcement effect of the clamping plate 11.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, there are multiple slots 5, and the multiple slots 5 are evenly spaced along the circumference of the limiting sleeve 4. It should be noted that the tightening bolt 8 is provided with a corresponding number of holes 9 as the number of slots 5. The provision of multiple slots 5 and holes 9 further increases the stability of the tightening bolt 8.

[0042] like Figure 1 As shown, in this embodiment, the vertical plate 2 is integrally formed with the bottom plate 1. It should be noted that the vertical plate 2 and the bottom plate 1 are integrally formed to increase the rigidity of the entire device.

[0043] like Figure 1 As shown, in this embodiment, the connection between the riser 2 and the base plate 1 is an arc-shaped structure 7. It should be noted that by providing the arc-shaped structure 7 between the riser 2 and the base plate 1, the structure between the riser 2 and the base plate 1 is strengthened, and is less likely to break than a right-angle connection.

[0044] like Figure 1 As shown, in this embodiment, reinforcing ribs 6 are provided between the vertical plate 2 and the bottom plate 1, and the reinforcing ribs 6 connect the vertical plate 2 and the bottom plate 1. It should be noted that the provision of the reinforcing ribs 6 further increases the rigidity between the vertical plate 2 and the bottom plate 1.

[0045] The principle of this utility model is:

[0046] In the initial state, the two vertical plates 2 are respectively located on both sides of the rail 10, and the two vertical plates 2 are respectively inclined in the direction close to the rail 10. When the clamping plates 11 on both sides of the rail 10 are to be clamped, the tightening bolts 8 on the vertical plates 2 are screwed so that the ends of the tightening bolts 8 gradually approach the clamping plates 11. When the tightening bolts 8 come into contact with the clamping plates 11, the tightening bolts 8 are further screwed. At this time, the vertical plates 2 are pushed outward by the tightening bolts 8, thereby causing the vertical plates 2 to undergo elastic deformation and provide elastic force toward the clamping plates 11, so that the fixing effect of the clamping plates 11 is better.

[0047] After the clamping bolt 8 tightens the splint 11 , the staff inserts the pin into the slot 5 and the hole 9 so that the slot 5 limits the pin, thereby preventing the clamping bolt 8 from rotating in the circumferential direction and improving the reinforcement effect of the splint 11 .

[0048] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0049] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
