Description

Technical Field

[0001] This utility model relates to the field of foundation pile reinforcement technology, and more specifically, it relates to a foundation pile reinforcement device for highway bridges. Background Technology

[0002] In the construction of highway bridges, foundation piles are the foundation that supports the bridge structure. Over long periods of use, foundation piles are subjected to long-term external impacts from rainwater and wind erosion. To reduce safety hazards, reinforcement devices are needed to strengthen them.

[0003] Patent document CN209907381U discloses a highway bridge foundation pile reinforcement device. This device includes a foundation pile body, with bases on both sides of the bottom of the foundation pile body. A first mounting hole is formed at the top of each base, and a fixing plate is fixedly connected to the top of the base. A connecting plate is fixedly connected to the top of the fixing plate, and a second clamping plate is fixedly connected to one side of each connecting plate. This invention solves the problem of poor protection for foundation piles in existing highway bridge foundation pile reinforcement devices by using a combination of the foundation pile body, bases, first clamping plates, first mounting holes, a limiting shell, a handle, a first rotating rod, a connecting plate, a second clamping plate, a mounting plate, a fixing plate, a threaded sleeve, a reinforcement plate, a threaded rod, a second rotating rod, a driving wheel, a belt, a driven wheel, a second mounting hole, and a through hole. This highway bridge foundation pile reinforcement device has the advantage of good protection for foundation piles and is worthy of promotion.

[0004] However, during use, the device requires rotating two handles sequentially and adjusting them back and forth to ensure that the two reinforcing plates can fit tightly together and effectively reinforce the pile body. Due to the complexity of the operation and the influence of human factors, it is difficult to ensure that the reinforcement support strength of the two reinforcing plates on the pile body is completely consistent throughout the process. This may lead to uneven reinforcement effect, which in turn affects the overall stability and safety of the pile. Secondly, the device does not have a component to fix the rotating handle during use. If an external force accidentally hits the handle, causing it to rotate, it will not only destroy the already adjusted reinforcement state, but may also affect the stability and reliability of the reinforcement effect, and may even cause the reinforcement device to fail, thus threatening the structural safety of the pile. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a highway bridge foundation pile reinforcement device to solve the technical problem mentioned in the background art, which requires rotating two handles in sequence and making back-and-forth adjustments during the use of the device, making it difficult to ensure that the reinforcement support strength of the two reinforcement plates on the foundation pile body is completely consistent throughout the process.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a highway bridge foundation pile reinforcement device, comprising two bases, each base having an arc-shaped support plate fixedly mounted on it, a plurality of first screws rotatably mounted on one side of the support plate, each first screw having a sleeve threaded onto it, and a reinforcement plate fixedly mounted at one end of two corresponding upper and lower sleeves, the support plate having two drive chambers, each first screw having a bevel gear fixedly mounted at one end extending into the drive chamber, the support plate having a limiting groove, a drive plate movably mounted within the limiting groove, the upper and lower ends of the drive plate extending into the two drive chambers respectively and fixedly mounted with bevel gear belts, the drive plate having a movable hole, a second screw movably mounted within the movable hole, and one end of the second screw passing through the movable hole and threadedly connected to the support plate.

[0009] The present invention is further provided with a handle fixed on one side of the drive plate to facilitate pushing the drive plate.

[0010] The present invention is further provided that the handle has a fixing chamber for easy fixing of the handle.

[0011] The present invention is further configured such that one end of the second screw extends into the fixed chamber and is fixedly connected to a driving block, the driving block being threadedly connected to the fixed chamber, and a cross groove being provided on one side of the driving block to facilitate driving the second screw to rotate.

[0012] The present invention is further provided that each of the bases has multiple mounting holes to facilitate fixing the base.

[0013] The present invention is further configured such that one of the support plates is provided with two fixed shells, and a lead screw is rotatably provided in each fixed shell. One end of the lead screw is rotatably connected to the support plate, and the other end of the lead screw passes through the fixed shell and is fixedly provided with a throttle handle to facilitate the rotation of the lead screw.

[0014] The present invention is further provided with two limiting plates on another support plate to facilitate fixing the support plate.

[0015] The present invention is further configured such that each lead screw is threaded with a limiting shell, the limiting shell is movably disposed within the fixed shell, and one end of the limiting shell passes through the fixed shell and has a slot that cooperates with the limiting plate, so as to facilitate fixing the limiting plate.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a highway bridge foundation pile reinforcement device, which has the following beneficial effects:

[0018] 1. The base, mounting holes, support plate, first screw, sleeve, reinforcing plate, drive chamber, bevel gear, limiting groove, drive plate and bevel gear belt work together. By moving the drive plate, multiple first screws rotate simultaneously, so that multiple reinforcing plates move simultaneously. This allows for rapid reinforcement of the foundation pile. At the same time, the reinforcement support strength of multiple reinforcing plates on the foundation pile is completely consistent, ensuring the uniformity of the reinforcement effect and the overall stability and safety of the foundation pile.

[0019] 2. By using the movable hole, second screw, handle, cross groove, fixed chamber and drive block in combination, the handle and drive plate can be fixed to the support plate after the drive plate is used, thereby preventing the drive plate and handle from moving under accidental collisions, ensuring the reinforcement effect, avoiding affecting the stability and reliability of the reinforcement, and reducing the threat to the structural safety of the foundation pile.

[0020] 3. By using a combination of a fixed housing, lead screw, throttle, limit plate, limit housing, and slot, two support plates can be quickly fixed together. The entire fixing process can be completed without the need for professional tools to tighten multiple bolts, making it simple to operate and easy to install. Attached Figure Description

[0030] Please see Figures 1-5 A highway bridge foundation pile reinforcement device includes two bases 1, each base 1 having an arc-shaped support plate 2 fixedly mounted on it. Multiple first screws 3 are rotatably mounted on one side of each support plate 2, and each first screw 3 is threaded with a sleeve 4. A reinforcement plate 5 is fixedly mounted at one end of two corresponding upper and lower sleeves 4. Two drive chambers 6 are provided inside the support plate 2. A bevel gear 7 is fixedly mounted at one end of each first screw 3 extending into the drive chamber 6. A limiting groove 8 is provided on the support plate 2, and a drive plate 9 is movably mounted within the limiting groove 8. The upper and lower ends of the drive plate 9 extend into the two drive chambers 6 respectively and are fixedly mounted with bevel gear belts 10. Multiple mounting holes 17 are provided on each base 1.

[0031] In this embodiment, two bases 1, along with two support plates 2, are placed outside the foundation pile. The two bases 1 are then fixed to the ground via mounting holes 17. At this point, the two limiting grooves 8 and the two drive plates 9 form annular rings. Pushing the handle 13 causes the two drive plates 9 to move along the limiting grooves 8. The drive plates 9 then rotate the conical toothed belt 10. Since the conical toothed belt 10 meshes with the conical gear 7, the conical gear 7 rotates, causing the first screw 3 to rotate. Because the first screw 3 is threadedly connected to the sleeve 4, the sleeve 4 moves, causing the reinforcing plates 5 to move. This allows multiple reinforcing plates 5 to move simultaneously, reinforcing the foundation pile. The threads on the two corresponding first screws 3 are in opposite directions, ensuring that the two corresponding sleeves 4 move in the same direction simultaneously.

[0032] Please see Figures 1-5As one embodiment for fixing the drive plate 9 and the handle 13: the drive plate 9 is provided with a movable hole 11, and a second screw 12 is movably disposed in the movable hole 11. One end of the second screw 12 passes through the movable hole 11 and is threadedly connected to the support plate 2. A handle 13 is fixedly disposed on one side of the drive plate 9. A fixing chamber 14 is provided inside the handle 13. One end of the second screw 12 extends into the fixing chamber 14 and is fixedly connected to a drive block 15. The drive block 15 is threadedly connected to the fixing chamber 14. A cross groove 16 is provided on one side of the drive block 15.

[0033] Specifically, after the handle 13 is used, insert the screwdriver into the fixing chamber 14 and into the cross groove 16, rotate the screwdriver so that the screwdriver drives the drive block 15 to rotate through the cross groove 16. Since the drive block 15 is threadedly connected to the fixing chamber 14, the drive block 15 moves while rotating. The drive block 15 drives one end of the second screw 12 to pass through the movable hole 11 and be threadedly connected to the support plate 2, thereby fixing the handle 13 and the drive plate 9 to the support plate 2.

[0034] Please see Figures 1-5 As one embodiment for fixing the two support plates 2: one of the support plates 2 is provided with two fixing shells 18, and each fixing shell 18 is rotatably provided with a lead screw 19. One end of the lead screw 19 is rotatably connected to the support plate 2, and the other end of the lead screw 19 passes through the fixing shell 18 and is fixedly provided with a throttle 20. The other support plate 2 is provided with two limiting plates 21, and each lead screw 19 is threaded with a limiting shell 22. The limiting shell 22 is movably disposed in the fixing shell 18, and one end of the limiting shell 22 passes through the fixing shell 18 and is provided with a groove 23 that cooperates with the limiting plate 21.

[0035] Specifically, when the two support plates 2 come into contact, the two handles 20 are rotated in sequence. The handles 20 drive the lead screw 19 to rotate. Since the lead screw 19 is threadedly connected to the limiting shell 22, the limiting shell 22 moves along the fixed shell 18. When the limiting shell 22 moves to the bottom of the fixed shell 18, the limiting plate 21 will be inserted into the slot 23 in the limiting shell 22, thereby fixing the limiting plate 21 and thus fixing the two support plates 2 together.

[0036] In summary, when using the overall equipment:

[0037] When the entire reinforcement device needs to be installed, the two bases 1 drive the two support plates 2 to be placed outside the foundation pile. The two bases 1 are fixed to the ground through the mounting holes 17. At this time, the foundation pile is located at the center between the two bases. The two limiting grooves 8 and the two drive plates 9 form a ring. The two support plates 2 are in contact. The two handles 20 are rotated in sequence. The handles 20 drive the lead screw 19 to rotate. Since the lead screw 19 is threadedly connected to the limiting shell 22, the limiting shell 22 moves along the fixed shell 18. When the limiting shell 22 moves to the bottom of the fixed shell 18, the limiting plate 21 will be inserted into the slot 23 in the limiting shell 22, thereby fixing the limiting plate 21 and fixing the two support plates 2 together.

[0038] When multiple reinforcing plates 5 need to be moved simultaneously to reinforce the foundation pile, push the handle 13. The handle 13 drives two drive plates 9 to move along the limiting groove 8. The drive plates 9 drive the conical toothed belt 10 to rotate. Since the conical toothed belt 10 is meshed with the conical gear 7, the conical gear 7 rotates. The conical gear 7 drives the first screw 3 to rotate. Since the first screw 3 is threadedly connected to the sleeve 4, the sleeve 4 moves. The sleeve 4 drives the reinforcing plates 5 to move, so that multiple reinforcing plates 5 move simultaneously to reinforce the foundation pile. The threads on the two corresponding first screws 3 are in opposite directions, thus ensuring that the two corresponding sleeves 4 move in the same direction simultaneously.

[0039] When it is necessary to fix the state of the drive plate 9 and the handle 13, after the handle 13 is used, insert the screwdriver into the fixing chamber 14 and into the cross groove 16, rotate the screwdriver so that the screwdriver drives the drive block 15 to rotate through the cross groove 16. Since the drive block 15 is threadedly connected to the fixing chamber 14, the drive block 15 moves while rotating. The drive block 15 drives one end of the second screw 12 to pass through the movable hole 11 and be threadedly connected to the support plate 2, thereby fixing the handle 13 and the drive plate 9 to the support plate 2.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
