Description

Technical Field

[0001] This utility model relates to the field of highway bridge pile foundation reinforcement technology, and in particular to a highway bridge pile foundation reinforcement device. Background Technology

[0002] The pile foundation of a highway bridge is the foundation of the entire highway bridge, and its stability directly affects the safety and service life of the highway bridge. Most highway bridge pile foundations are affected by natural geographical conditions, service time, and other factors, which reduces the stability of the bridge pile foundation. Therefore, reinforcement devices are usually used for the pile foundation.

[0003] In related technologies, reinforcement devices include multiple clamping assemblies, each comprising an electric actuator and a clamping plate. The electric actuator is driven to the clamping plate. When using the reinforcement device to reinforce a pile foundation, the electric actuators of each clamping assembly drive the corresponding clamping plate to move, ultimately causing multiple clamping plates to clamp the pile foundation together, thereby achieving reinforcement. However, this type of reinforcement device can only clamp pile foundations of a specific size. When the size of the pile foundation to be reinforced changes, a different reinforcement device is required, significantly increasing construction costs. Utility Model Content

[0004] The purpose of this utility model is to provide a highway bridge pile foundation reinforcement device, which aims to solve the technical problem that the existing reinforcement devices have low versatility, cannot adapt to pile foundations of various sizes, and result in high construction costs.

[0005] This application provides a highway bridge pile foundation reinforcement device, including a base plate and at least two clamping assemblies connected to the base plate. The base plate has a through hole for the pile foundation to pass through. All clamping assemblies are arranged at intervals along the circumference of the through hole. Each clamping assembly includes a rolling assembly and an elastic clamping plate. At least one rolling assembly is detachably connected to the end of the clamping plate. The rolling end of the rolling assembly protrudes from the surface of the clamping plate facing the through hole axis for rolling contact with the pile foundation. All clamping plates are configured to move in a direction close to the through hole axis to jointly clamp the pile foundation.

[0006] The beneficial effects of the highway bridge pile foundation reinforcement device provided by this utility model are:

[0007] When using this highway bridge pile foundation reinforcement device, each clamping plate moves along the direction close to the perforation axis, that is, each clamping plate gradually approaches the pile foundation. As the clamping plate gradually approaches the pile foundation, the rolling end of the rolling assembly first contacts the pile foundation and rolls on the outer surface of the pile foundation. Due to the elasticity of the clamping plate, as the rolling end continues to roll, the end of the clamping plate gradually opens outward, allowing the middle part of the clamping plate to continue moving towards the pile foundation and eventually press against the outer surface of the pile foundation. Once the middle part of the clamping plate is pressed against the pile foundation, the rolling assembly is disassembled, causing the rolling end of the rolling assembly to retract into the clamping plate until the end of the clamping plate presses against the outer surface of the pile foundation. At this point, the entire clamping plate can press against the outer surface of the pile foundation, effectively increasing the contact area between the clamping plate and the outer surface of the pile foundation, thereby improving the reinforcement effect of this highway bridge pile foundation reinforcement device. It can be seen that this highway bridge pile foundation reinforcement device can adapt to pile foundations of various sizes, greatly improving the versatility of highway bridge pile foundation reinforcement devices and reducing construction costs.

[0008] Furthermore, because this highway bridge pile foundation reinforcement device uses rolling components, the deformation of the clamping plate becomes smoother, and the ends of the clamping plate can open outward more smoothly, which can effectively reduce the wear of the clamping plate and the pile foundation, thereby extending their service life.

[0009] Optionally, the clamping plate has a mounting groove that extends radially through two opposite surfaces of the clamping plate along the perforation. The rolling assembly includes a mounting block and a rolling element. The mounting groove is detachably connected to the mounting groove, and the rolling element is movably connected to the mounting block. The rolling element is the rolling end.

[0010] Optionally, the inner wall surface of the mounting groove near the through-hole axis protrudes to form a boss, and the boss has a threaded hole. The mounting block includes a mounting part and a connecting part. The connecting part is disposed on the surface of the mounting part near the through-hole axis. The mounting part has a through hole. The rolling element is movably connected to the connecting part. The rolling assembly also includes a fastener, which passes through the through hole and is threadedly connected to the threaded hole.

[0011] Optionally, the clamping plate may be detachably connected to rolling components at both ends in the circumferential direction of the perforation.

[0012] Optionally, the clamping assembly also includes an electric push rod and a connecting rod, wherein the electric push rod is driven to connect with the connecting rod, and the end of the connecting rod away from the electric push rod is fixedly connected to the clamping plate.

[0013] Optionally, the clamping assembly further includes a fixed plate and an elastic element. The fixed plate is fixedly connected to the connecting rod and is located between the clamping plate and the electric push rod. The elastic element is located between the fixed plate and the clamping plate, with one end of the elastic element fixedly connected to the fixed plate and the other end of the elastic element fixedly connected to the clamping plate.

[0014] Optionally, the fixing plate has a first receiving groove on its surface facing the clamping plate, and the end of the elastic member is located in the first receiving groove.

[0015] Optionally, the clamping plate has a second receiving groove on its surface facing the fixing plate, and the end of the elastic member is located in the second receiving groove.

[0016] Optionally, the bottom surface of the fixed plate is provided with a slider, and the top surface of the base plate is provided with a groove, and the slider is slidably connected to the groove.

[0017] Optionally, a first positioning plane is provided on the outer circular surface of the end of the connecting rod away from the electric push rod, and a positioning groove is provided on the surface of the clamping plate near the electric push rod, with a second positioning plane provided in the positioning groove.

[0040] Please refer to Figures 1 to 6 The present invention will now describe a highway bridge pile foundation reinforcement device 100 according to an embodiment of the present invention.

[0041] Please refer to Figure 1 , Figure 2 and Figure 5 This application provides a highway bridge pile foundation reinforcement device 100, comprising a base plate 10 and at least two clamping assemblies 20 connected to the base plate 10. The base plate 10 has a through hole 11 through which the pile foundation 200 passes. All clamping assemblies 20 are arranged circumferentially at intervals along the through hole 11. Each clamping assembly 20 includes a rolling assembly 21 and an elastic clamping plate 22. At least one rolling assembly 21 is detachably connected to the end of the clamping plate 22. The rolling end of the rolling assembly 21 protrudes from the surface of the clamping plate 22 facing the axis of the through hole 11 for rolling contact with the pile foundation 200. All clamping plates 22 are configured to move along a direction close to the axis of the through hole 11 to collectively clamp the pile foundation 200. Specifically, the perforation 11 penetrates the upper and lower surfaces of the base plate 10 in the vertical direction. This highway bridge pile foundation reinforcement device 100 is suitable for highway bridge pile foundations that are cylindrical. The clamping plate 22 is an arc-shaped plate, and the rolling component 21 is disposed at the end of the clamping plate 22 in the circumferential direction of the perforation 11.

[0042] When using this highway bridge pile foundation reinforcement device 100, each clamping plate 22 moves along the direction close to the axis of the perforation 11, that is, each clamping plate 22 gradually approaches the pile foundation 200. As the clamping plate 22 gradually approaches the pile foundation 200, the rolling end of the rolling assembly 21 first contacts the pile foundation 200 and rolls on the outer surface of the pile foundation 200. Because the clamping plate 22 is elastic, as the rolling end continues to roll, the end of the clamping plate 22 gradually opens outward, so that the middle part of the clamping plate 22 can continue to move towards the pile foundation 200 and finally stick to the outer surface of the pile foundation 200. After the middle portion of the clamping plate 22 is tightly attached to the pile foundation 200, the rolling assembly 21 is disassembled, causing the rolling end of the rolling assembly 21 to retract into the clamping plate 22 until the end of the clamping plate 22 is tightly attached to the outer surface of the pile foundation 200. At this point, the entire clamping plate 22 is tightly attached to the outer surface of the pile foundation 200, effectively increasing the contact area between the clamping plate 22 and the outer surface of the pile foundation 200, thereby improving the reinforcement effect of this highway bridge pile foundation reinforcement device 100. It is evident that this highway bridge pile foundation reinforcement device 100 can adapt to pile foundations 200 of various sizes, greatly improving the versatility of the highway bridge pile foundation reinforcement device 100 and reducing construction costs.

[0043] Furthermore, since the highway bridge pile foundation reinforcement device 100 uses a rolling component 21, the deformation of the clamping plate 22 becomes smoother, and the end of the clamping plate 22 can open outward more smoothly, which can effectively reduce the wear of the clamping plate 22 and the pile foundation 200, thereby extending their service life.

[0044] It is understandable that the number of clamping components 20 can be two, three or more, as long as they can clamp the pile foundation 200, and there is no limitation here.

[0045] In another embodiment of this application, please refer to Figure 4 and Figure 5 The clamping plate 22 has an installation groove 221 that extends radially through two opposing surfaces of the clamping plate 22 along the through hole 11. The rolling assembly 21 includes an installation block 211 and a rolling element 212. The installation groove 221 is detachably connected within the installation groove 221, and the rolling element 212 is movably connected to the installation block 211. The rolling element 212 is the aforementioned rolling end. During the operation of this highway bridge pile foundation reinforcement device 100, the rolling element 212 rolls on the outer surface of the pile foundation 200, causing the end of the clamping plate 22 to continuously open outward. When the middle part of the clamping plate 22 is pressed against the outer surface of the pile foundation 200, the installation block 211 is removed, causing the rolling element 212 to retract into the clamping plate 22, thereby allowing the end of the clamping plate 22 to press against the outer surface of the pile foundation 200.

[0046] It is understood that the rolling element 212 can be a cylindrical roller or a spherical roller, as long as it can roll on the outer surface of the pile foundation 200, and is not limited here. In this embodiment, the rolling element 212 is a roller that rolls in the up-down direction.

[0047] In another embodiment of this application, please refer to Figure 4 The inner wall surface of the mounting groove 221 near the axis of the through hole 11 protrudes to form a boss 222. The boss 222 has a threaded hole 2221. The mounting block 211 includes a mounting part 2111 and a connecting part 2112. The connecting part 2112 is disposed on the surface of the mounting part 2111 near the axis of the through hole 11. The mounting part 2111 has a through hole 2113. The rolling element 212 is movably connected to the connecting part 2112. The rolling assembly 21 also includes a fastener. The fastener passes through the through hole 2113 and is threadedly connected to the threaded hole 2221.

[0048] Specifically, the threaded hole 2221 is formed on the surface of the boss 222 away from the axis of the through hole 11 and extends radially along the through hole 11. The through hole 2113 penetrates the two opposing surfaces of the mounting portion 2111 radially along the through hole 11. When the middle portion of the clamping plate 22 is pressed against the outer surface of the pile foundation 200, loosening the fasteners will allow the rolling element 212 to retract into the clamping member, thereby allowing the end of the clamping plate 22 to press against the outer surface of the pile foundation 200.

[0049] In this embodiment, a threaded connection is used to achieve a detachable connection between the mounting block 211 and the mounting groove 221. On the one hand, this improves the connection strength between the mounting block 211 and the mounting groove 221, preventing the rolling element 212 from failing to roll on the outer surface of the pile foundation 200. On the other hand, it improves the disassembly efficiency of the mounting block 211 and the mounting groove 221.

[0050] It is understood that fasteners can be bolts, screws, or headless screws, as long as they can be threaded into the threaded hole 2221, and there are no restrictions on this.

[0051] In another embodiment of this application, please refer to Figure 1 and Figure 2 The clamping plate 22 has rolling components 21 detachably connected to both ends of the perforation 11 in the circumferential direction. This configuration can further improve the reinforcement effect of the highway bridge pile foundation reinforcement device 100 on the pile foundation 200, and further reduce the wear of the clamping plate 22 and the pile foundation 200, thereby further extending their service life.

[0052] In another embodiment of this application, please refer to Figure 1 and Figure 2The clamping assembly 20 also includes an electric push rod 23 and a connecting rod 24. The electric push rod 23 is driven to connect with the connecting rod 24, and the end of the connecting rod 24 away from the electric push rod 23 is fixedly connected to the clamping plate 22. During operation, the electric push rod 23 drives the connecting rod 24 to move radially along the through hole 11, thereby causing the clamping plate 22 to move radially along the through hole 11, thus enabling multiple clamping plates 22 to clamp the pile foundation 200 together.

[0053] In another embodiment of this application, please refer to Figures 1 to 3 The clamping assembly 20 also includes a fixing plate 25 and an elastic element 26. The fixing plate 25 is fixedly connected to the connecting rod 24 and is located between the clamping plate 22 and the electric push rod 23. The elastic element 26 is located between the fixing plate 25 and the clamping plate 22, with one end of the elastic element 26 fixedly connected to the fixing plate 25 and the other end of the elastic element 26 fixedly connected to the clamping plate 22. The elastic element 26 is a spring. The setting of the elastic element 26 allows the clamping plate 22 to contact the outer surface of the pile foundation 200 more tightly, which is beneficial to improving the reinforcement effect of the highway bridge pile foundation reinforcement device 100 on the pile foundation 200.

[0054] In another embodiment of this application, please refer to Figure 6 The fixing plate 25 has a first receiving groove 251 on its surface facing the clamping plate 22, and the end of the elastic member 26 is located in the first receiving groove 251. The first receiving groove 251 facilitates the installation of the elastic member 26. In addition, when the clamping plate 22 deforms, the elastic member 26 will bend slightly in addition to being compressed. The wall of the first receiving groove 251 abuts against the elastic member 26, which reduces the risk that the elastic member 26 may detach from the fixing plate 25 or the clamping plate 22 due to a large degree of bending.

[0055] In another embodiment of this application, please refer to Figure 3 and Figure 4 The clamping plate 22 has a second receiving groove 223 on its surface facing the fixing plate 25, and the end of the elastic member 26 is located in the second receiving groove 223. The second receiving groove 223 is provided to facilitate the installation of the elastic member 26 and to reduce the risk that the elastic member 26 may detach from the fixing plate 25 or the clamping plate 22 due to a large degree of bending.

[0056] In another embodiment of this application, please refer to Figure 6The bottom surface of the fixed plate 25 is provided with a slider 252, and the top surface of the base plate 10 is provided with a groove 12, with the slider 252 slidably connected to the groove 12. Specifically, the extension direction of the groove 12 is parallel to the movement direction of the connecting rod 24. The arrangement of the groove 12 and the slider 252 can, on the one hand, improve the positioning accuracy of the clamping plate 22, thereby improving the contact effect between the clamping plate 22 and the pile foundation 200, and thus improving the reinforcement effect of the highway bridge pile foundation reinforcement device 100 on the pile foundation 200. On the other hand, the base plate 10 can support the fixed plate 25 through the slider 252 to avoid deformation of the telescopic end of the electric push rod 23 due to excessive total weight of the fixed plate 25, connecting rod 24, clamping plate 22 and rolling assembly 21, which is beneficial to improving the contact effect between the clamping plate 22 and the pile foundation 200.

[0057] In another embodiment of this application, please refer to Figure 3 and Figure 4 The outer circumference of the connecting rod 24 away from the electric push rod 23 is provided with a first positioning plane 241, and the surface of the clamping plate 22 near the electric push rod 23 is provided with a positioning groove 224, which is provided with a second positioning plane 2241. This arrangement can improve the installation accuracy of the clamping plate 22 and is beneficial to improving the reinforcement effect of the highway bridge pile foundation reinforcement device 100 on the pile foundation 200.

[0058] In another embodiment of this application, a plurality of ground nails (not shown) are also provided on the base plate 10. The ground nails are used to fix the highway bridge pile foundation reinforcement device 100 to the ground.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
