Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe pile construction equipment, specifically a steel pipe pile driving correction device. Background Technology

[0002] Steel pipe sheet piles are a structural form consisting of three parts: steel pipe piles, steel sheet piles, and connecting interlocks. They are widely used in projects such as wharf forewalls, foundation pit support, and cofferdams. The steel pipe piles and steel sheet piles form the main structure, while the interlocks are welded to the sides of the steel pipe piles, serving as connectors between the pipe piles and sheet piles and as guides during pile driving. During construction, the steel pipe piles are typically driven into place first, followed by the sheet piles driven in along the interlocks. If the verticality or torsion deviation of the first-driven steel pipe piles is poorly controlled, the spacing between adjacent interlocks will be inconsistent with the width of the sheet piles, or the line connecting the two pipe pile interlocks will not coincide with the line connecting the sheet pile interlocks. When the deviation exceeds the free opening and bending capacity of the sheet piles, the sheet piles will be difficult to drive in, and interlocks may even disengage or the sheet piles may tear, ultimately causing sand leakage and damage to the steel pipe sheet pile structure, seriously threatening project safety. Therefore, the accuracy requirements for the verticality and torsion of the steel pipe piles in steel pipe sheet pile structures are more stringent and crucial than in conventional engineering projects.

[0003] To ensure the accuracy of steel pipe pile driving, a vibratory hammer in conjunction with a positioning frame (guide frame) is typically used for pile driving control during the initial stages of lifting, positioning, and driving. This method yields good results. However, typical positioning frames can only control the displacement of the pipe pile, which is often prone to rotation during driving in complex geological conditions. While positioning frames equipped with locking and limiting devices can simultaneously restrict both displacement and rotation of the pipe pile, their height is generally 10-20 meters. When the steel pipe pile reaches the top of the positioning frame, the frame must be removed before driving can continue. This means that in the later stages of driving, the steel pipe pile will lack the control of the positioning frame, significantly increasing the risk of pile tilting or rotation.

[0004] When pile misalignment occurs, since there is currently no dedicated pile correction device or method, the common practice on site is to control the boom to swing back and forth and left and right under the action of a vibratory hammer, or to use steel wire ropes to tie the pile body and pull it. These are relatively direct and crude methods with low correction accuracy and efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a steel pipe pile driving correction device to solve the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel pipe pile driving correction device, comprising a device body, a through hole at the center of the device body, four rectangularly distributed sliding holes on the device body, a transmission slider slidably arranged in the sliding holes, an annular groove communicating with the four sliding holes in the device body, a transmission ring rotatably installed in the annular groove, four arc-shaped guide grooves spaced circumferentially at one end of the transmission ring near the transmission slider, a sliding shaft protruding from each of the four transmission sliders, the four sliding shafts slidably arranged in the four arc-shaped guide grooves respectively, a rotating groove communicating with the annular groove in the device body, a drive gear rotatably installed in the rotating groove, a tooth groove meshing with the drive gear on the transmission ring, a servo motor mounted on the device body, and the output shaft of the servo motor mounted on the drive gear.

[0009] Preferably, each of the four transmission sliders has two symmetrical connecting blocks at one end that is close to each other, and rollers are rotatably mounted on the connecting blocks.

[0010] Preferably, each of the four sliding holes has a limiting groove on its inner wall, and each of the four transmission sliders has a limiting slider that is adapted to the limiting groove.

[0011] Preferably, the main body of the device has four threaded holes arranged in a matrix, and a threaded rod is rotatably installed in the threaded holes.

[0012] Preferably, a handwheel is provided at one end of the threaded rod, and a support block is provided at the other end of the threaded rod.

[0013] Preferably, the end of the servo motor furthest from the drive gear is exposed.

[0014] Preferably, all four sliding holes penetrate the main body of the device and extend into the through hole.

[0015] Compared with the prior art, this utility model provides a steel pipe pile driving correction device with the following beneficial effects: Through the cooperation of the transmission slider and rollers, the main body of the device can be placed at the pile hole and the center of the through hole is aligned with the center of the pile hole during use. At this time, the steel pipe pile is in the through hole. The servo motor drives the drive gear to rotate, which in turn causes the transmission ring to rotate in the annular groove. With the double limit of the arc-shaped guide groove and the sliding hole, the transmission slider slides along the sliding hole when the sliding shaft on the transmission slider slides along the arc-shaped guide groove. This allows the four transmission sliders to move closer to each other synchronously and press against the outer surface of the steel pipe pile through the rollers on the transmission sliders, thereby realizing the centering and correction of the steel pipe pile.

[0025] Please see Figure 1-5A steel pipe pile driving correction device includes a main body 1, a through hole 2 at the center of the main body 1, four rectangular sliding holes 8 on the main body 1, a transmission slider 9 slidably arranged in the sliding holes 8, an annular groove 11 communicating with the four sliding holes 8 in the main body 1, a transmission ring 12 rotatably installed in the annular groove 11, four arc-shaped guide grooves 13 spaced apart along the circumference at one end of the transmission ring 12 near the transmission slider 9, a sliding shaft 18 protruding on each of the four transmission sliders 9, the four sliding shafts 18 slidably arranged in the four arc-shaped guide grooves 13 respectively, a rotating groove 14 communicating with the annular groove 11 in the main body 1, a drive gear 15 rotatably installed in the rotating groove 14, a tooth groove 16 meshing with the drive gear 15 on the transmission ring 12, a servo motor 7 installed on the main body 1, and the output shaft of the servo motor 7 mounted on the drive gear 15.

[0026] By cooperating with the transmission slider 9 and roller 4, the main body 1 of the device can be placed at the pile hole and the center of the through hole 2 can be aligned with the center of the pile hole during use. At this time, the steel pipe pile is in the through hole 2. The servo motor 7 can drive the drive gear 15 to rotate, which in turn causes the transmission ring 12 to rotate in the annular groove 11. Under the double limit of the arc guide groove 13 and the sliding hole 8, the transmission slider 9 can slide along the sliding hole 8 when the sliding shaft 18 on the transmission slider 9 slides along the arc guide groove 13. This allows the four transmission sliders 9 to move closer to each other synchronously and be pressed against the outer surface of the steel pipe pile by the roller 4 on the transmission slider 9, thereby achieving the centering and correction of the steel pipe pile.

[0027] Specifically, in this embodiment, each of the four transmission sliders 9 has two symmetrical connecting blocks 3 at one end that is close to each other, and rollers 4 are rotatably mounted on the connecting blocks 3.

[0028] By setting roller 4, the friction force of the correction mechanism on the steel pipe pile during pile driving can be reduced.

[0029] Specifically, in this embodiment, a limiting groove is provided on the inner wall of each of the four sliding holes 8, and a limiting slider 17 that is adapted to the limiting groove is provided on each of the four transmission sliders 9.

[0030] The movement range of the transmission slider 9 can be limited by the cooperation between the limiting slide groove and the limiting slider 17.

[0031] Specifically, in this embodiment, the main body 1 of the device has four threaded holes arranged in a matrix. A threaded rod 5 is rotatably installed in the threaded holes. A handwheel 6 is provided at one end of the threaded rod 5, and a support block 10 is provided at the other end of the threaded rod 5.

[0032] Through the cooperation of four threaded rods 5 and support blocks 10, the threaded rods 5 can be rotated by turning the handwheel 6, which in turn causes the support blocks 10 to be raised and lowered vertically, thus making the device adaptable to different terrains.

[0033] Specifically, in this embodiment, the end of the servo motor 7 furthest from the drive gear 15 is exposed, which can effectively ensure the heat dissipation requirements of the servo motor 7 during operation.

[0034] Specifically, in this embodiment, all four sliding holes 8 penetrate the main body 1 of the device and extend into the through hole 2.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
