Technical Field
[0001] This utility model belongs to the field of piling equipment technology, specifically a piling equipment for water conservancy construction. Background Technology
[0002] Piling equipment in water conservancy construction is a key tool that uses mechanical power to drive piles into the foundation, thereby enhancing the bearing capacity of the foundation. It can transfer the load of the superstructure to deep, stable soil layers, effectively preventing foundation settlement and deformation, and ensuring the stability of the foundations of water conservancy projects such as dams, sluices, and pumping stations. In scenarios such as river and lake management and reservoir construction, piling equipment can select different pile types according to geological conditions, adapting to complex working conditions such as soft soil foundations and gravel layers. It can not only improve the foundation's resistance to sliding and overturning, but also provide solid support for structures in flood control and water conveyance projects, ensuring the long-term safe operation of water conservancy facilities under the impact of water flow and loads.
[0003] When a pile contacts the ground, the pile hammer needs to transfer enormous energy to the pile to cause it to sink. During this process, the pile suddenly decelerates due to ground resistance, while the pile hammer maintains significant inertia, resulting in a strong rigid collision between the two. This high-frequency rigid collision subjectes the pile hammer to immense impact and stress, leading to fatigue cracks, localized deformation, and even fracture in its internal structure, significantly shortening its service life. Furthermore, existing pile limiting structures typically rely on numerous screws for fixing the pile. When replacing piles of different specifications, the position and dimensions of the limiting device must be readjusted, which is not only cumbersome and time-consuming, increasing construction costs and timelines, but also makes it difficult to quickly and accurately adapt to different pile specifications, reducing construction efficiency and pile driving accuracy. Therefore, this application proposes a pile driving device for hydraulic construction. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a pile driving device for water conservancy construction, which effectively solves the problems of easy damage to the pile hammer and inconvenience in limiting the position of piles of different specifications in pile driving devices.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic construction piling device, comprising a base and a shock-absorbing mechanism. Multiple rollers are fixedly installed on the base. A first motor is installed at the upper end of the base, and a transmission wheel is fixedly installed at the output end of the first motor. An installation plate is fixedly installed at the upper end of the base, and multiple guide wheels are fixedly installed on the installation plate. A transmission belt is wound around the transmission wheel and guide wheels, and a pile hammer is fixedly connected to one end of the transmission belt. The shock-absorbing mechanism includes an installation frame fixedly installed at the bottom of the pile hammer. Two opposing triangular sliding plates are slidably connected to the installation frame. Friction plates are fixedly installed on both sides of the triangular sliding plates. A resistance plate that slides against the friction plates is fixedly installed on the installation frame. A rectangular plate located between the two triangular sliding plates is slidably connected to the inclined surface of the triangular sliding plates. A spring is fixedly installed on the rectangular plate. A pile column is installed below the pile hammer, and a groove is provided on the pile column. The spring passes through the installation frame and is located within the groove.
[0006] Preferably, a counterweight block located on one side of the first motor is fixedly installed at the upper end of the base, and a plurality of fixing columns fixedly connected to the first motor are fixedly installed at the upper end of the base.
[0007] Preferably, a connecting plate is fixedly installed on one side of the mounting plate, the conveyor belt passes through the connecting plate and is slidably connected to it, one of the guide wheels is fixedly installed on the upper end of the connecting plate, and the pile hammer is located below the connecting plate.
[0008] Preferably, a circular frame is fixedly installed at the bottom of the pile hammer, which is opposite to the mounting frame, and two opposing retaining rings are fixedly installed inside the circular frame.
[0009] Preferably, a T-shaped block is fixedly installed at the upper end of the pile column, which slides against the inner wall of the circular frame, and the T-shaped block can abut against the retaining ring.
[0010] Preferably, a fixed frame is fixedly mounted on the mounting plate, and a second motor is fixedly mounted on the fixed frame. The output end of the second motor passes through the fixed frame and is rotatably connected to it.
[0011] Preferably, the output end of the second motor is fixedly connected to a first threaded rod, one end of the first threaded rod is fixedly connected to a rotating rod, and a second threaded rod that is rotatably connected to the fixed frame is fixedly installed on the rotating rod.

Each of the first threaded rod and the second threaded rod is fitted with a limiting block that is threadedly connected to the first threaded rod and the second threaded rod. The limiting block slides against the inner wall of the fixed frame and can abut against the pile.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up a shock-absorbing mechanism, and utilizing the cooperation between the triangular sliding plate, friction plate, resistance plate, rectangular plate and spring, when the pile contacts the ground, it will generate a reaction force on the pile, which in turn will generate pressure on the spring. The compression of the spring will push the rectangular plate and drive the rectangular plate to move. The movement of the rectangular plate will drive the triangular sliding plate to move to both sides. The movement of the triangular sliding plate will drive the resistance plate to move. The movement of the resistance plate will abut against the friction plate, thereby generating friction. The friction and the reaction force generated by the spring can offset the reaction force of the ground on the pile, thereby avoiding excessive rigid contact between the pile hammer and the pile and causing damage, and ensuring the stability of the pile during operation. At the same time, by utilizing the cooperation between the limiting block, the first threaded rod and the second threaded rod, different piles can be quickly positioned and limited.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0022] Depend on Figures 1-5 The present invention includes a base 1 and a shock-absorbing mechanism. Multiple rollers 2 are fixedly installed on the base 1. A first motor 3 is installed on the upper end of the base 1. Multiple fixed columns 14 fixedly connected to the first motor 3 are fixedly installed on the upper end of the base 1. A transmission wheel 5 is fixedly installed on the output end of the first motor 3. An installation plate 13 is fixedly installed on the upper end of the base 1. Multiple guide wheels 7 are fixedly installed on the installation plate 13. A transmission belt 6 is wound around the transmission wheel 5 and the guide wheels 7. A pile hammer 9 is fixedly connected to one end of the transmission belt 6. A counterweight block 4 located on one side of the first motor 3 is fixedly installed on the upper end of the base 1. A connecting plate 8 is fixedly installed on one side of the installation plate 13. The transmission belt 6 passes through the connecting plate 8 and is slidably connected to it. One of the guide wheels 7 is fixedly installed on the upper end of the connecting plate 8. The pile hammer 9 is located below the connecting plate 8.
[0023] During operation, the first motor 3 is turned on, which drives the transmission wheel 5 to rotate. The rotation of the transmission wheel 5 drives the transmission belt 6 to move, which drives the pile hammer 9 to move upward. The pile hammer 9 drives the pile column 10 to move. After reaching the predetermined position, the pile hammer 9 is released. The pile column 10 is no longer under tension and will move downward to contact the ground to perform pile driving. The pile column 10 is raised and lowered repeatedly to complete the pile driving work.
[0024] The shock absorption mechanism includes a mounting frame 21 fixedly installed at the bottom of the pile hammer 9. Two opposing triangular sliding plates 15 are slidably connected to the mounting frame 21. Friction plates 16 are fixedly installed on both sides of the triangular sliding plates 15. A resistance plate 24 that slides against the friction plates 16 is fixedly installed on the mounting frame 21. A rectangular plate 17 located between the two triangular sliding plates 15 is slidably connected to the inclined surface of the triangular sliding plates 15. A spring 22 is fixedly installed on the rectangular plate 17. A pile column 10 is installed below the pile hammer 9. The pile column 10 has a groove 23. The spring 22 passes through the mounting frame 21 and is located in the groove 23. A circular frame 18 that is opposite to the mounting frame 21 is fixedly installed at the bottom of the pile hammer 9. Two opposing retaining rings 19 are fixedly installed inside the circular frame 18. A T-shaped block 20 that slides against the inner wall of the circular frame 18 is fixedly installed at the upper end of the pile column 10. The T-shaped block 20 can abut against the retaining rings 19.
[0025] When the pile 10 contacts the ground and begins pile driving, the pile 10 exerts pressure on the ground, and the ground exerts a reaction force on the pile 10. The pile 10 exerts pressure on the spring 22, which is compressed. This compression pushes the rectangular plate 17 and causes it to move. The movement of the rectangular plate 17 causes the triangular sliding plate 15 to move to both sides. The upward force of the spring 22 on the rectangular plate 17 is decomposed into an upward force and a force to both sides, thus reducing the pressure on the spring 22 and preventing it from being damaged by excessive force. The movement of the triangular sliding plate 15 also causes the resistance plate 24 to move. The resistance plate 24 then comes into contact with the friction plate 16, generating friction. The friction and the reaction force generated by the spring 22 can counteract the reaction force of the ground on the pile 10, thereby preventing excessive rigid contact between the pile hammer 9 and the pile 10 and ensuring the stability of the pile 10 during operation.
[0026] A fixed frame 25 is fixedly installed on the mounting plate 13. A second motor 12 is fixedly installed on the fixed frame 25. The output end of the second motor 12 passes through the fixed frame 25 and is rotatably connected to it. A first threaded rod 26 is fixedly connected to the output end of the second motor 12. A rotating rod 28 is fixedly connected to one end of the first threaded rod 26. A second threaded rod 27, which is rotatably connected to the fixed frame 25, is fixedly installed on the rotating rod 28. The threads on the first threaded rod 26 and the second threaded rod 27 are opposite in direction. A limiting block 11 is fitted on both the first threaded rod 26 and the second threaded rod 27 and is threadedly connected to the first threaded rod 26 and the second threaded rod 27. The limiting block 11 slides against the inner wall of the fixed frame 25 and can abut against the pile column 10.
[0027] During operation, the pile 10 is placed between two limiting blocks 11, and the second motor 12 is turned on. The output end of the second motor 12 will drive the first threaded rod 26 to rotate, the first threaded rod 26 will drive the rotating rod 28 to rotate, and the rotating rod 28 will drive the second threaded rod 27 to rotate. Since the limiting blocks 11 slide against the fixed frame 25, and the threads on the first threaded rod 26 and the second threaded rod 27 are opposite in direction, the rotation of the first threaded rod 26 and the second threaded rod 27 will drive the two limiting blocks 11 to move relative to each other. The movement of the limiting blocks 11 will abut against the pile 10, thereby limiting the pile 10.
[0028] Furthermore, the circular frame 18 and the pile hammer 9 are connected by screws. When it is necessary to replace the pile 10 with a different specification, the second motor 12 is turned on. The output end of the second motor 12 will drive the first threaded rod 26 to rotate. The first threaded rod 26 will drive the rotating rod 28 to rotate. The rotating rod 28 will drive the second threaded rod 27 to rotate. The rotation of the first threaded rod 26 and the second threaded rod 27 will cause the two limit blocks 11 to move relative to each other. The movement of the limit blocks 11 will cause them to move away from the pile 10, and the pile 10 will no longer be limited. Unscrew the screws used to connect the circular frame 18 and the pile hammer 9, replace the pile 10 with the required size, and turn on the second motor 12 again. The output end of the second motor 12 will drive the first threaded rod 26 to rotate. The first threaded rod 26 will drive the rotating rod 28 to rotate. The rotating rod 28 will drive the second threaded rod 27 to rotate. The rotation of the first threaded rod 26 and the second threaded rod 27 will cause the two limit blocks 11 to move relative to each other. The movement of the limit blocks 11 will cause them to abut against the pile 10, thereby limiting the pile 10.
[0029] Working principle: During operation, the pile 10 is placed between the two limiting blocks 11, and the second motor 12 is turned on. The output end of the second motor 12 will drive the first threaded rod 26 to rotate, the first threaded rod 26 will drive the rotating rod 28 to rotate, and the rotating rod 28 will drive the second threaded rod 27 to rotate. Since the limiting blocks 11 slide against the fixed frame 25, and the threads on the first threaded rod 26 and the second threaded rod 27 are opposite in direction, the rotation of the first threaded rod 26 and the second threaded rod 27 will drive the two limiting blocks 11 to move relative to each other. The movement of the limiting blocks 11 will abut against the pile 10, thereby limiting the pile 10.
[0030] Furthermore, the circular frame 18 and the pile hammer 9 are connected by screws. When it is necessary to replace the pile 10 of different specifications, turn on the second motor 12. The output end of the second motor 12 will drive the first threaded rod 26 to rotate. The first threaded rod 26 will drive the rotating rod 28 to rotate. The rotating rod 28 will drive the second threaded rod 27 to rotate. The rotation of the first threaded rod 26 and the second threaded rod 27 will cause the two limit blocks 11 to move relative to each other. The movement of the limit blocks 11 will move away from the pile 10, and the pile 10 will no longer be limited. Unscrew the screws used to connect the circular frame 18 and the pile hammer 9, replace the pile 10 of the required size, and turn on the second motor 12 again. The output end of the second motor 12 will drive the first threaded rod 26 to rotate. The first threaded rod 26 will drive the rotating rod 28 to rotate. The rotating rod 28 will drive the second threaded rod 27 to rotate. The rotation of the first threaded rod 26 and the second threaded rod 27 will cause the two limit blocks 11 to move relative to each other. The movement of the limit blocks 11 will abut against the pile 10, thereby limiting the pile 10.
[0031] Turn on the first motor 3, which will drive the transmission wheel 5 to rotate. The rotation of the transmission wheel 5 will drive the transmission belt 6 to move. The transmission belt 6 will drive the pile hammer 9 to move upward. The pile hammer 9 will drive the pile column 10 to move. After reaching the predetermined position, release the pile hammer 9. The pile column 10 will no longer be under tension and will move downward to contact the ground to carry out pile driving. Repeat the lifting and lowering of the pile column 10 to complete the pile driving work.
[0032] When the pile 10 contacts the ground and begins pile driving, the pile 10 exerts pressure on the ground, and the ground exerts a reaction force on the pile 10. The pile 10 exerts pressure on the spring 22, which is compressed. This compression pushes the rectangular plate 17 and causes it to move. The movement of the rectangular plate 17 causes the triangular sliding plate 15 to move to both sides. The upward force of the spring 22 on the rectangular plate 17 is decomposed into an upward force and a force to both sides, thus reducing the pressure on the spring 22 and preventing it from being damaged by excessive force. The movement of the triangular sliding plate 15 also causes the resistance plate 24 to move. The resistance plate 24 then comes into contact with the friction plate 16, generating friction. This friction and the reaction force generated by the spring 22 can counteract the reaction force of the ground on the pile 10, thereby preventing excessive rigid contact between the pile hammer 9 and the pile 10 and ensuring the stability of the pile 10 during operation.
