Description

Technical Field

[0001] This utility model relates to the field of non-destructive reinforcement technology for rails, specifically to a non-destructive reinforcement device for rails. Background Technology

[0002] Non-destructive rail reinforcement devices are used to reinforce welded rails. They generally include clamps on both sides of the rail, bolts passing through the two clamps, and nuts threadedly connected to the bolts.

[0003] Announcement No. CN204644803U discloses a non-destructive rail reinforcement device, including clamping plates, bolts, and limiting supports. The clamping plates are fixed to both sides of the rail web by a combination of adhesive bonding and freezing. Each pair of clamping bodies is located on both sides of the rail, with the lower end of the clamping body clamping the bottom of the rail and the upper end clamping the clamping plate. A limiting support is provided between the bottoms of each pair of clamping bodies.

[0004] In the aforementioned non-destructive rail reinforcement device, bolts, nuts, and two clamping bodies are used to clamp the plates located on both sides of the rail, so that the two clamping bodies clamp the two sides of the rail. However, due to manufacturing errors of the clamping bodies, the bolts may be tilted relative to the clamping bodies during the process of the bolts and nuts abutting against the clamping bodies. In this case, an angle will be formed when the bolt head abuts against the clamping body, resulting in point contact between the bolt head and the clamping body. Alternatively, an angle will be formed when the nut abuts against the clamping body, resulting in point contact between the nut and the clamping body. Point contact cannot effectively apply a uniform load to the two clamping bodies, which may cause loosening between the two clamping bodies and affect the reinforcement of the rail.

[0034] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model is further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0035] In order to solve the technical problem that the head of the bolt 21 and the nut and the clamping body of the rail 3 reinforcing device can be point contact, the utility model provides a rail nondestructive reinforcing device, which can avoid point contact between the head of the bolt 21 and the clamping assembly 1.

[0036] It should be noted that the nondestructive reinforcing device is used for reinforcing the rail 3, but is not limited to this. In the utility model, the nondestructive reinforcing device is only taken as an example of being applied to the rail 3 reinforcing, and the principle of the nondestructive reinforcing device being applied to other types of equipment is substantially the same as that of being applied to the rail 3 reinforcing, which will not be described here.

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 It is a structural schematic view of the rail nondestructive reinforcing device in an embodiment of the utility model, Figure 2 It is Figure 1 a local enlarged view of A in the utility model, the rail nondestructive reinforcing device comprises two clamping assemblies 1 and a connecting assembly 2, the connecting assembly 2 comprises a bolt 21, a nut 22 and a deformation pad 23, the threaded section of the bolt 21 can be rotatably arranged in the two clamping assemblies 1, the nut 22 is threadedly connected with the bolt 21, the deformation pad 23 is arranged between the clamping assembly 1 and the nut 22, and / or the deformation pad 23 is located between the clamping assembly 1 and the head of the bolt 21; wherein the deformation pad 23 can be deformed under the extrusion of the nut 22.

[0038] Specifically, when reinforcing the rail 3, the two clamping assemblies 1 are arranged on the two sides of the rail 3, then the bolt 21 is passed through the two clamping assemblies 1, and the head of the bolt 21 is attached to the clamping assembly 1, then the deformation pad 23 is attached to the clamping assembly 1, the nut 22 is threadedly connected with the bolt 21, and the nut 22 is abutted against one side of the deformation pad 23 away from the clamping assembly 1, during the process of tightening the nut 22, when there is an included angle between the end face of the nut 22 and the clamping assembly 1, the nut 22 extrudes the deformation pad 23 and drives the deformation pad 23 to deform, so that the end face of the nut 22 towards the clamping assembly 1 is attached to the clamping assembly 1 through the deformation pad 23, until the end face of the nut 22 is attached to the deformation pad 23 and the clamping assembly 1 through the deformation pad 23, even if there is an included angle between the nut 22 and the clamping assembly 1, the nut 22 can be attached to the clamping assembly 1 through the deformation pad 23 between the nut 22 and the clamping assembly 1, avoiding point contact between the nut 22 and the clamping assembly 1.

[0039] It should be understood that the clamping assembly 1 can be various types of clamping supports, clamping blocks, etc., the two clamping assemblies 1 can be arranged at intervals on the two sides of the rail 3, and can also be arranged on the two sides of the rail 3 while abutting each other.

[0040] It should be understood that the deformation pad 23 can be provided between the clamping assembly 1 and the nut 22, or between the clamping assembly 1 and the head of the bolt 21, or both between the clamping assembly 1 and the nut 22 and between the clamping assembly 1 and the head of the bolt 21.

[0041] It should be understood that the deformation washer 23 can be fitted onto the bolt 21, or it can be placed on both sides and one side of the bolt 21, specifically, as shown below. Figure 2 As shown, in one embodiment, the deformation pad 23 has a fixing hole relative to the bolt 21 and is fitted onto the bolt 21 through the fixing hole.

[0042] It should be understood that the deformation pad 23 can be of any shape; it can be a complete ring or an arc-shaped structure. Specifically, in one embodiment, the deformation pad 23 is ring-shaped.

[0043] It should be understood that bolt 21 can also be replaced by a combination of bolt 21 and nut.

[0044] In one embodiment, the hardness of the deformation pad 23 gradually increases during the compression process.

[0045] In this embodiment, the deformation pad 23 undergoes plastic deformation when compressed. The deformation pad 23 gradually deforms when compressed, and during the compression process, the force resisting deformation of the deformation pad 23 gradually increases. When the deformation pad 23 is compressed to a certain extent, it can no longer be compressed. At this time, the deformation pad 23 has a high hardness and can better transmit the clamping force applied by the nut 22 to the clamping assembly 1.

[0046] It should be understood that there are many materials that can achieve the functions of the deformation pad 23 mentioned above, such as copper, red copper, and aluminum alloy.

[0047] To prevent the fixed nut 22 from loosening, therefore, as follows: Figure 2 As shown, in one embodiment, the rail non-destructive reinforcement device further includes a limiting component 4, which is connected to the clamping component 1 and has a limiting state of abutting against the nut 22 and a disengaging state of disengaging from the nut 22; when in the limiting state, the limiting component 4 restricts the nut 22 from rotating relative to the bolt 21.

[0048] By setting the limiting component 4, after the nut 22 is fixed, the limiting component 4 is switched to the limiting state. At this time, the limiting component 4 can restrict the nut 22 from rotating relative to the bolt 21, so as to prevent the nut 22 from loosening.

[0049] It should be understood that the limiting component 4 can be a limiting pin or a limiting bolt 21, etc., specifically, such as Figure 2As shown, in one of the embodiments, the limiting assembly 4 forms a limiting groove 4a relative to the nut 22, when the limiting assembly 4 is in the limiting state, the inner wall of the limiting groove 4a abuts against the outer wall of the nut 22, so as to limit the rotation of the nut 22 relative to the bolt 21.

[0050] After the nut 22 is fixed, the inner wall of the limiting groove 4a of the limiting assembly 4 abuts against the outer wall of the nut 22, at this time, the surface between the limiting assembly 4 and the outer wall of the nut 22 is in surface-to-surface fit, which can limit the rotation of the nut 22 relative to the bolt 21.

[0051] It should be understood that the limiting assembly 4 can be connected to the clamping assembly 1 in a sliding manner or in a rotating manner. Specifically, as shown in Figure 2 As shown, in one of the embodiments, one end of the limiting assembly 4 is connected to the clamping assembly 1 in a rotating manner; the limiting groove 4a penetrates the other end of the limiting assembly 4.

[0052] In the embodiment, the limiting assembly 4 is connected to the clamping assembly 1 in a rotating manner, however, when the limiting assembly 4 is connected in a rotating manner, the limiting groove 4a cannot be sleeved on the nut 22, therefore, in the embodiment, the limiting groove 4a penetrates the other end of the limiting assembly 4, so that the limiting groove 4a can be sleeved on the nut 22 through the rotating limiting assembly 4.

[0053] In order to clamp the steel rail 3, the clamping assembly 1 can be a clamping bracket, a clamping block, etc., specifically, as shown in Figure 1 As shown, in one of the embodiments, the clamping assembly 1 includes a clamping plate 11 and a clamping piece 12, the clamping plate 11 is used to abut against the web of the steel rail 3, and the clamping piece 12 abuts against the side of the clamping plate 11 away from the steel rail 3; the threaded end of the bolt 21 penetrates through the two clamping pieces 12, and the head of the bolt 21 and the deformation pad 23 abut against the sides of the two clamping assemblies 1 away from each other, respectively.

[0054] When it is necessary to reinforce the steel rail 3, the clamping plate 11 clamps the steel rail 3, the clamping piece 12 abuts against the side of the clamping plate 11 away from the steel rail 3, the threaded end of the bolt 21 penetrates through the two clamping pieces 12, and then the head of the bolt 21 and the deformation pad 23 abut against the sides of the two clamping assemblies 1 away from each other, respectively, the nut 22 is tightened, the bolt 21 and the nut 22 clamp the two clamping pieces 12, and the two clamping pieces 12 clamp the clamping plate 11 on the steel rail 3, thereby achieving the reinforcement of the steel rail 3.

[0055] It should be understood that the clamping piece 12 can be a clamping bracket, a clamping seat, etc., specifically, as shown in Figure 1As shown, in one of the embodiments, the clamping piece 12 comprises a first clamping part 121 and a second clamping part 122, the first clamping part 121 abuts against the side of the clamping plate 11 away from the rail 3, and the second clamping part 122 is connected with the first clamping part 121 and is arranged below the rail bottom of the rail 3 and abuts against the rail bottom of the rail 3; the threaded end of the bolt 21 is rotatably arranged through the two second clamping parts 122, and the head of the bolt 21 and the nut 22 respectively abut against the sides of the two second clamping parts 122 of the two clamping assemblies 1 away from each other.

[0056] When the bolt 21 and the nut 22 clamp the clamping piece 12, the first clamping part 121 abuts against the side of the clamping plate 11 away from the rail 3, and the second clamping part 122 abuts against the bottom of the rail 3, thereby realizing the locking between the first clamping part 121 and the second clamping part 122 and the rail 3, so that the first clamping part 121 and the second clamping part 122 cannot shake relative to the rail 3 after being clamped.

[0057] It should be understood that the first clamping part 121 and the second clamping part 122 can be blocks, strips, seats, etc.

[0058] When reinforcing the rail 3, the bolt 21 needs to pass through the two clamping pieces 12, in order to avoid opening holes on the rail 3, therefore, as shown, Figure 1 in one of the embodiments, the two second clamping parts 122 are each provided with a through hole 122a, and the through hole 122a is arranged at the bottom of the rail 3; the threaded end of the bolt 21 is rotatably arranged through the clamping assembly 1 through the through hole 122a.

[0059] In the embodiment, by arranging the through hole 122a on the second clamping part 122 and at the bottom of the rail 3, the bolt 21 can pass through the bottom of the rail 3, thereby avoiding opening holes on the rail 3, and reinforcing the rail 3 without opening holes.

[0060] Among them, the limiting assembly 4 can be rotatably connected with the first clamping part 121 and / or the second clamping part 122 through a rotating shaft or a rotating pin, and specifically, as shown, Figure 1 and Figure 2 in one of the embodiments, the clamping piece 12 further comprises two support plates 123, the two support plates 123 are arranged at the side of the first clamping part 121 away from the rail 3 and are connected with the first clamping part 121; and the limiting assembly 4 is rotatably connected with the two support plates 123 through a rotating shaft.

[0061] By arranging the two support plates 123, the limiting assembly 4 and the clamping assembly 1 are rotatably connected.

[0062] In order to insulate between the clamping plate 11 and the first clamping part 121, therefore, in one of the embodiments, the clamping plate 11 and the first clamping part 121 are spaced apart by an insulating block 5.

[0063] By setting the insulating block 5, the insulating block 5 can be spaced between the clamp plate 11 and the first clamping part 121, the second clamping part 122 is made of insulating material, or an insulating material can also be provided between the second clamping part 122 and the rail 3.

[0064] It should be understood that the insulating block 5 can be connected with the first clamping part 121 in the form of abutting, bonding, inserting, clamping and bolt 21 connection.

[0065] Because the installation space below part of the rail 3 is limited, therefore, as shown in one of the embodiments, the thickness of the second clamping part 122 at the position below the rail 3 is 20-45mm. Figure 1

[0066] In the embodiment, by limiting the thickness of the second clamping part 122 at the position below the rail 3 to be 20-45mm, the second clamping part 122 can smoothly pass through the reinforcement of the rail 3 with smaller installation space below, so that the rail reinforcement device can reinforce more types of rails 3.
