Description
Technical Field
[0001] This utility model relates to the field of piling engineering technology, and more specifically, to a piling device for building engineering. Background Technology
[0002] Piling devices are specialized engineering equipment used to precisely implant piles into the ground, and are widely used in building foundations, bridge foundations, marine engineering, and other fields. Their core consists of a drive system, positioning mechanism, clamping components, and control system. They press the pile into the ground through hydraulic impact, high-frequency vibration, or static pressure. They also feature low noise and low vibration characteristics. Some devices are equipped with IoT modules for cloud-based management of construction data, and combined with recyclable pile structures, they improve construction accuracy and efficiency while reducing disturbance to the surrounding environment.
[0003] Current piling devices have limitations in their clamping mechanisms. For short piles, the clamping components can usually complete the basic clamping task. However, for ultra-long piles, the rigidity of ultra-long piles is insufficient to resist bending deformation caused by their own weight and external forces, given the inherent characteristics of the pile body. During hoisting or clamping, the pile body is prone to deflection due to its own weight, resulting in a "support at both ends and drooping in the middle" deflection. This causes the contact between the pile body and the clamping mechanism to change from "full-length contact" to "partial point contact." The clamping force cannot be evenly distributed on the pile surface, and the pressure at local contact points increases dramatically. Meanwhile, non-contact areas experience "swaying space" due to gaps. This "swaying space" greatly reduces the clamping force of the clamping mechanism on the pile body, and the excessive pressure at local contact points can also damage the pile body and the clamping mechanism. Therefore, this utility model provides a piling device for building engineering to solve the above problems. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a piling device for building engineering, which has the advantage of balancing the force points on the pile body and the clamping mechanism.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a piling device for building engineering, comprising a support column, a clamping mechanism slidably disposed on the support column, the clamping mechanism comprising a sliding sleeve slidably connected to the support column, a connecting plate for connecting adjacent sliding sleeves, an upper receiving plate and a lower receiving plate fixedly disposed on the connecting plate near the end of the construction pile, a clamping plate A that moves between the upper receiving plate and the lower receiving plate to approach or move away from the connecting plate, and a clamping plate B disposed on the side of the clamping plate A away from the upper receiving plate, the support column being disposed at each corner of a square structure, and the clamping mechanism being provided with a driving mechanism for driving the clamping plate A and the clamping plate B to move.
[0006] As a preferred technical solution of this utility model, the clamping mechanism is provided in multiple sets, and each set of the clamping mechanism is respectively arranged on the support column in multiple directions around the construction pile.
[0007] As a preferred embodiment of this utility model, the driving mechanism includes a forward and reverse motor fixedly mounted on the connecting plate, a connecting rod fixedly mounted on the output end of the forward and reverse motor, and a spring telescopic rod fixedly mounted on the end of the connecting rod away from the forward and reverse motor. The end of the spring telescopic rod away from the connecting rod passes through the clamping plate A and the clamping plate B in sequence and is rotatably connected to the limiting plate. The spring telescopic rod is rotatably connected to the clamping plate A and threadedly connected to the clamping plate B.
[0008] As a preferred embodiment of this utility model, multiple forward and reverse motors are provided and symmetrically arranged on the connecting plate.
[0009] As a preferred embodiment of the present invention, the driving mechanism further includes a hydraulic cylinder fixedly connected to the connecting plate and a hydraulic rod fixedly connected to the output end of the hydraulic cylinder, wherein the end of the hydraulic rod away from the hydraulic cylinder is fixedly connected to the clamping plate A.
[0010] As a preferred embodiment of this utility model, the clamping plate A and the clamping plate B are provided with arc-shaped notches, and the curvature of the inner surface of the arc-shaped notches is less than the curvature of the surface of the construction pile.
[0011] As a preferred embodiment of this utility model, a horizontal plate is fixedly installed at the top of the support column, and an opening is provided on the horizontal plate for the construction pile to enter.
[0012] As a preferred embodiment of this utility model, a level measuring instrument is fixedly installed on the level plate.
[0013] As a preferred technical solution of this utility model, the clamping mechanism on the horizontal plate is fixedly provided with a hydraulic cylinder at multiple positions, and a lifting rod is fixedly provided at the output end of the hydraulic cylinder. The end of the lifting rod away from the hydraulic cylinder is fixedly connected to the upper receiving plate on the corresponding clamping mechanism.
[0014] As a preferred technical solution of this utility model, a support plate is fixedly arranged between adjacent support columns corresponding to the lower part of the clamping mechanism. A fixing plate is fixedly arranged on the ground on one side of the support plate. A diagonal brace is arranged between the fixing plate and the support plate to provide support. One end of the diagonal brace is fixedly arranged on the fixing plate. A threaded rod is threadedly connected to the end of the diagonal brace near the support plate. One end of the threaded rod passes through the diagonal brace and is rotatably connected to the support plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. This utility model uses a forward and reverse motor to control the rotation of the connecting rod at the output end of the motor. The connecting rod drives the spring telescopic rod connected to it to rotate. The spring telescopic rod drives the clamping plate B connected to it to move towards the clamping plate A. The clamping plate A and the clamping plate B move closer to each other and fix the pile. The clamping mechanism is set in multiple positions between the support columns, which can surround the construction pile in multiple positions, making the clamping mechanism clamp the construction pile more comprehensively and stably.
[0017] 2. This utility model uses a hydraulic cylinder to control the hydraulic cylinder in the clamping mechanism located opposite the bending inflection point of the construction pile and at opposite ends. The hydraulic cylinder drives the hydraulic rod, which pushes the clamping plate A to move on the upper and lower receiving plates. The clamping plate A pushes the contact surface on the construction pile to move, reducing the bending amplitude of the construction pile and making the pressure of the construction pile on the clamping plate A and clamping plate B tend to be average, thereby reducing the risk of damage to the construction pile and the clamping mechanism.
[0018] 3. This utility model uses a diagonal brace plate to support the support plate, thereby supporting the support column and preventing the support column from tilting, which would cause the construction pile to tilt. A level measuring instrument is used to detect the levelness of the level plate. When the support column and level plate tilt due to the influence of the construction pile, the threaded rod can be rotated. The threaded rod pushes the support plate, and the support plate pushes the support column, thus correcting the tilt of the support column. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figures 1 to 5 As shown, this utility model provides a piling device for building engineering, including a support column 1, a clamping mechanism 2 slidably disposed on the support column 1, the clamping mechanism 2 including a sliding sleeve 21 slidably connected to the support column 1, a connecting plate 22 for connecting adjacent sliding sleeves 21, an upper receiving plate 23 and a lower receiving plate 231 fixedly disposed on the end of the connecting plate 22 near the construction pile and positioned opposite each other, a clamping plate A24 that moves between the upper receiving plate 23 and the lower receiving plate 231 towards or away from the connecting plate 22, and a clamping plate A24 disposed on the clamping plate A24 away from the upper receiving plate 22. The clamping plate B25 on one side of plate 23 and the support column 1 are set at each corner of the square structure. The clamping mechanism 2 is equipped with a driving mechanism 3 that drives the clamping plate A24 and clamping plate B25 to move. By increasing the vertical height of clamping plate A24 and clamping plate B25, the contact surface with the pile can be increased, thereby reducing the pressure on the contact surface with the pile and reducing the pressure damage to the pile and the pile driving device. Through the driving mechanism 3, the clamping plate A24 and clamping plate B25 can be clamped, released and moved, thereby correcting the bending of the construction pile to a certain extent.
[0027] Furthermore, multiple sets of clamping mechanisms 2 are provided, with each set of clamping mechanisms 2 respectively positioned on the support column 1 in multiple directions around the construction pile. The clamping mechanisms 2, positioned in multiple locations between the support columns 1, can surround the construction pile from multiple angles, making the clamping of the construction pile by the clamping mechanisms 2 more comprehensive and stable.
[0028] Furthermore, the drive mechanism 3 includes a forward and reverse motor 31 fixedly mounted on the connecting plate 22, a connecting rod 32 fixedly mounted on the output end of the forward and reverse motor 31, and a spring telescopic rod 33 fixedly mounted on the end of the connecting rod 32 away from the forward and reverse motor 31. The end of the spring telescopic rod 33 away from the connecting rod 32 passes through the clamping plate A24 and the clamping plate B25 in sequence and is rotatably connected to the limiting plate 34. The spring telescopic rod 33 is rotatably connected to the clamping plate A24 and threadedly connected to the clamping plate B25. It controls the forward and reverse motor 31, which controls the connecting rod 32 at the output end to rotate. The connecting rod 32 drives the spring telescopic rod 33, which is threadedly connected to it, to rotate. The spring telescopic rod 33 drives the clamping plate B25, which is threadedly connected to it, to move toward the clamping plate A24. The clamping plate A24 and the clamping plate B25 move closer to each other and are fixed in place. The limiting plate 34 acts as a limit to prevent the clamping plate B25 from detaching from the spring telescopic rod 33.
[0029] It is worth noting that multiple forward and reverse motors 31 are symmetrically arranged on the connecting plate 22, which makes the control of the spring telescopic rod 33 on the clamping plate A24 more stable.
[0030] It should be noted that the drive mechanism 3 also includes a hydraulic cylinder 35 fixedly connected to the connecting plate 22 and a hydraulic rod 36 fixedly connected to the output end of the hydraulic cylinder 35. The end of the hydraulic rod 36 away from the hydraulic cylinder 35 is fixedly connected to the clamping plate A24. The hydraulic cylinder 35 in the clamping mechanism 2, located opposite the bending inflection point of the construction pile and at opposite ends, can be controlled by electrical connection. The hydraulic cylinder 35 drives the hydraulic rod 36, which pushes the clamping plate A24 to move on the upper receiving plate 23 and the lower receiving plate 231. The clamping plate A24 pushes the contact surface on the construction pile to move, reducing the bending amplitude of the construction pile and making the pressure of the construction pile on the clamping plate A24 and the clamping plate B25 tend to be average, thereby reducing the risk of damage to the construction pile and the clamping mechanism 2.
[0031] Furthermore, clamping plates A24 and B25 are provided with arc-shaped notches 26. The curvature of the inner surface of the arc-shaped notches 26 is less than the curvature of the surface of the construction pile. In the opposite case, clamping plates A24 and B25 only have their two ends in contact with the pile. The contact area is small, which makes it easy to cause damage and is not easy to stabilize.
[0032] Furthermore, a horizontal plate 4 is fixedly installed at the top of the support column 1. An opening 41 is provided on the horizontal plate 4 for the construction pile to enter. The horizontal plate 4 connects the support column 1 into a whole.
[0033] Specifically, a level measuring instrument 42 is fixedly installed on the level plate 4 to detect the overall tilt of the pile driving device.
[0034] It should be noted that hydraulic cylinders 5 are fixedly installed on the horizontal plate 4 corresponding to multiple directional clamping mechanisms 2. A lifting rod 51 is fixedly installed at the output end of the hydraulic cylinder 5. The end of the lifting rod 51 away from the hydraulic cylinder 5 is fixedly connected to the upper receiving plate 23 on the corresponding clamping mechanism 2. After the piling is completed, the hydraulic cylinder 5 can lift the clamping mechanism 2 below the corresponding position to the initial position.
[0035] Furthermore, a support plate 6 is fixedly installed below the clamping mechanism 2 between adjacent support columns 1. A fixed plate 61 is fixedly installed on the ground on one side of the support plate 6. A diagonal brace 62 is installed between the fixed plate 61 and the support plate 6 to provide support. One end of the diagonal brace 62 is fixedly installed on the fixed plate 61, and a threaded rod 63 is threadedly connected to the end of the diagonal brace 62 near the support plate 6. One end of the threaded rod 63 passes through the diagonal brace 62 and is rotatably connected to the support plate 6. The diagonal brace 62 is used to support the support plate 6, thereby supporting the support column 1 and preventing the support column 1 from tilting, which would cause the construction pile to tilt. The level measuring instrument 42 is used to detect the levelness of the level plate 4. When the support column 1 and the level plate 4 tilt due to the influence of the construction pile, the threaded rod 63 can be rotated. The threaded rod 63 pushes the support plate 6, and the support plate 6 pushes the support column 1 to correct the tilt of the support column 1.
[0036] Working principle and usage process of this utility model:
[0037] When using this construction piling device, the pile is first lifted by a crane and inserted into the device through the opening 41 on the horizontal plate 4. One end of the pile passes through the opening 41 and then through the arc-shaped notches 26 on the clamping plates A24 and B25. The forward and reverse motors 31 are controlled to rotate the connecting rod 32 at the output end. The connecting rod 32 drives the spring telescopic rod 33, which is threaded to it, to rotate. The spring telescopic rod 33 drives the clamping plate B25, which is threaded to it, to move towards the clamping plate A24. The clamping plates A24 and B25 move closer to each other and fix the pile. The clamping mechanism 2 is set in multiple positions between the support columns 1, which can surround the construction pile in multiple positions, making the clamping mechanism 2 clamp the construction pile more comprehensively and stably. Increasing the vertical height of clamping plates A24 and B25 increases the contact area with the pile, thereby reducing the pressure on the contact surface and minimizing pressure damage to the pile and driving device. During this process, one end of the spring telescopic rod 33 gradually shortens as clamping plate B25 moves. By placing sensors and other detection equipment inside clamping plates A24 and B25, the pressure of the pile at various positions on each clamping plate can be detected, thus determining the bending direction, bending point, and bending amplitude of the pile. The detection equipment is electrically connected to the control center. Next, the staff can control the hydraulic cylinder 35 to work based on the detected information. The hydraulic cylinder 35 in the clamping mechanism 2, located opposite the bending inflection point of the construction pile and at the opposite ends, can be controlled by electrical connection. The hydraulic cylinder 35 drives the hydraulic rod 36, which pushes the clamping plate A24 to move on the upper receiving plate 23 and the lower receiving plate 231. The clamping plate A24 pushes the contact surface on the construction pile to move, reducing the bending amplitude of the construction pile and making the pressure of the construction pile on the clamping plate A24 and the clamping plate B25 tend to be average, thereby reducing the risk of damage to the construction pile and the clamping mechanism 2. During the pile driving process, the sliding sleeve 21 slides on the support column 1, and the clamping mechanism 2 moves downward with the construction pile. After the pile driving is completed, the forward and reverse motor 31 drives the clamping plate A24 and clamping plate B25 to release. The hydraulic cylinder 5 drives the upper receiving plate 23, and the upper receiving plate 23 drives the clamping mechanism 2 to move to the initial position. The inclined brace plate 62 is used to support the support plate 6, thereby supporting the support column 1 and preventing the support column 1 from tilting, which would cause the construction pile to tilt. The level measuring instrument 42 is used to detect the levelness of the level plate 4. When the support column 1 and the level plate 4 tilt due to the influence of the construction pile, the threaded rod 63 can be rotated. The threaded rod 63 pushes the support plate 6, and the support plate 6 pushes the support column 1 to correct the tilt of the support column 1.
