The upper detection device is used to vertically abut against the pipe pile being measured, and a plumb bob assembly is suspended on the upper detection device. The lower detection device is used to support the pipe pile being measured, and a correction disc for positioning the plumb bob assembly is provided on the lower detection device. The upper and lower detection devices are connected by a detachable vertical connecting rod. It can be used simultaneously for pile foundation positioning and pile verticality correction; it is convenient to use, allowing for use at any time during the process, and provides clear measurements. It can be used simultaneously for pile foundation positioning and pile verticality correction, and the two measurement methods can be switched by disassembling the vertical connecting rod; it is convenient to use, allowing for use at any time during the process, and provides clear measurements.

[0004] The existing technology has the following problems:

[0005] Although the above-mentioned utility model can correct the verticality of the pile, it requires that the device be located on a horizontal support surface before verticality correction can be performed, and it cannot automatically adjust the correction force according to changes in the verticality of the pile foundation, making it difficult to effectively improve the quality and efficiency of pile foundation construction. Utility Model Content

[0006] This utility model provides a verticality correction device for port and wharf pile foundation construction to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0008] A verticality correction device for pile foundation construction at a port wharf includes a sleeve, an adjustment mechanism is provided on the outer periphery of the sleeve, and two fixing rings are installed on the outer periphery of the sleeve, with the adjustment mechanism located between the two fixing rings.

[0009] The sleeve is equipped with a correction mechanism inside.

[0010] Preferably, the adjusting mechanism includes a first ring and a second ring, both of which are installed on the outer periphery of the sleeve. A first threaded tube is installed on the outer periphery of the first ring, and a second threaded tube is installed on the outer periphery of the second ring. A threaded rod is internally threaded to the first threaded tube, and the second threaded tube is threaded to the end of the threaded rod away from the first threaded tube.

[0011] Preferably, a handwheel is installed in the middle of the threaded rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model provides a verticality correction device for port and wharf pile foundation construction. By setting an adjustment mechanism and with the help of multiple adjustment mechanisms working together between the sleeves, the position, angle and distance between the sleeves can be precisely adjusted from multiple directions and angles. This greatly improves the flexibility and comprehensiveness of the device for correcting the verticality of the pile foundation.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 - Figure 5 As shown, a verticality correction device for port and wharf pile foundation construction includes a sleeve 1, which serves as the main frame of the correction device and provides the installation foundation and support for other components. It protects the internal correction mechanism 4 from damage by external factors; during pile foundation construction, it acts as a positioning and guiding component, guiding the pile foundation to sink vertically; its outer periphery provides suitable installation positions for the adjustment mechanism 2 and the fixing rings 3, ensuring the stability and reliability of the device structure. The outer periphery of the sleeve 1 is provided with the adjustment mechanism 2, which is used to adjust the distance between the two sleeves 1. Two fixing rings 3 are installed on the outer periphery of the sleeve 1, and the adjustment mechanism 2 is located between the two fixing rings 3.

[0027] The casing 1 is equipped with a correction mechanism 4, which achieves precise verticality correction through direct contact with the pile foundation.

[0028] like Figure 1 and Figure 4As shown, the adjusting mechanism 2 includes a first ring 21 and a second ring 22. Both rings 21 and 22 are installed on the outer circumference of the sleeve 1. As the basic connecting components of the adjusting mechanism 2, rings 21 and 22 provide a stable mounting platform for threaded tubes 23 and 24. Threaded tube 23 is installed on the outer circumference of ring 21, and threaded tube 24 is installed on the outer circumference of ring 22. A threaded rod 25 is internally threaded onto the threaded tube 23, and threaded tube 24 is threaded onto the end of the threaded rod 25 furthest from the threaded tube 23. Threaded tubes 23 and 24 cooperate with the threaded rod 25, achieving the extension and retraction of the threaded rod 25 through the threaded connection. The threaded connection has a self-locking function, maintaining stability after adjustment to a suitable position, preventing loosening or displacement, and ensuring the accuracy and reliability of the adjustment. When adjusting the distance between the sleeves, the extension and retraction of the threaded tubes drives the movement of related components, achieving precise distance control.

[0029] like Figure 2 As shown, a handwheel 26 is installed in the middle of the threaded rod 25, providing a convenient operating interface for the operator. Manually rotating the handwheel 26 allows for easy control of the rotation of the threaded rod 25, enabling precise operation of the adjustment mechanism 2. Its ergonomic design provides a comfortable grip and effortless operation, improving construction efficiency.

[0030] like Figure 2 As shown, the correction mechanism 4 includes an arc-shaped plate 41, which is disposed inside the sleeve 1. Its arc-shaped design allows it to fit snugly against the outer surface of the pile foundation, increasing the contact area and improving the stability and accuracy of the correction. Under the action of the compression spring 44 and the sliding plate 46, the arc-shaped plate 41 remains in close contact with the pile foundation, automatically adjusting its position according to changes in the verticality of the pile foundation to provide continuous correction force. Multiple rollers 42 are installed inside the arc-shaped plate 41. When the pile foundation moves within the sleeve 1, the rollers 42 reduce the friction between the pile foundation and the arc-shaped plate 41, making the pile foundation move more smoothly and preventing damage or inaccurate correction due to friction. Simultaneously, the rollers 42 also act as guides, directing the vertical movement of the pile foundation.

[0031] like Figure 3As shown, a sliding rod 43 is installed on the outer periphery of the arc-shaped plate 41. The sliding rod 43 provides guidance for the movement of the arc-shaped plate 41, ensuring that the arc-shaped plate 41 maintains linear motion during movement and improving the motion accuracy of the correction mechanism 4. A sliding plate 46 is sleeved on the outer periphery of the sliding rod 43, serving as a support component for the compression spring 44. It can move under the drive of the threaded column 45, changing the spring compression state and limiting the range of motion of the sliding rod 43 to prevent the arc-shaped plate 41 from moving excessively and damaging the device. A compression spring 44 is provided on the side of the sliding plate 46 near the sleeve 1, providing elasticity to the arc-shaped plate 41 and keeping it in close contact with the pile foundation surface. When the pile foundation has a verticality deviation, the compression spring 44 can automatically adjust its elasticity according to the magnitude of the deviation, pushing the arc-shaped plate 41 to correct the pile foundation and ensure that the pile foundation is vertical. A limit plate 48 is installed on the end of the sliding rod 43 away from the arc-shaped plate 41 to prevent the sliding rod 43 from sliding out of the sleeve 1, ensuring safe movement. At the same time, the limit plate 48 can also limit the maximum displacement of the arc-shaped plate 41, preventing damage to the device when the pile foundation deviation is too large.

[0032] like Figure 3 As shown, a threaded post 45 is installed on the outer circumference of the sleeve 1, and a sliding plate 46 is threadedly connected to the outer circumference of the threaded post 45. Rotating the drive wheel 47 can drive the threaded post 45 to rotate, causing the sliding plate 46 to move and changing the compression amount of the compression spring 44, thereby achieving precise control of the correction force. The drive wheel 47 is installed on the side of the threaded post 45 away from the sleeve 1, providing an operating interface for the operator. Rotating the drive wheel 47 can drive the threaded post 45 to rotate, precisely adjusting the position of the sliding plate 46, and thus controlling the correction force. Its design is easy to operate and can improve construction efficiency and correction accuracy. The operator can combine the operation of the adjustment mechanism with the operation of the drive wheel to precisely control the correction force.

[0033] like Figure 2 As shown, a limiting rod 49 is installed on the outer periphery of the sleeve 1, and a sliding plate 46 is set on the outer periphery of the limiting rod 49. The limiting rod 49 further restricts the movement direction of the sliding plate 46, preventing the sliding plate 46 from deviating during movement, ensuring the movement accuracy and stability of the correction mechanism 4, and ensuring that the correction force can be accurately applied to the pile foundation.

[0034] The working principle of this utility model is as follows: During pile foundation construction, the sleeve 1 is first fitted onto the pile foundation. The operator rotates the handwheel 26 on each adjustment mechanism 2. Since the outer circumference of a single sleeve 1 can be connected to two adjustment mechanisms 2, through the coordinated action of multiple adjustment mechanisms 2, the position, angle, and distance between sleeves are initially adjusted, so that the sleeve 1 is approximately vertical and at a suitable spacing. Then, the drive wheel 47 is rotated to drive the threaded column 45 to rotate, causing the slide plate 46 to move on the threaded column 45. The slide plate 46 pushes the arc plate 41 to apply a corrective force to the pile foundation through the compression spring 44 and the slide rod 43. The roller 42 inside the arc plate 41 reduces the friction with the pile foundation, allowing the arc plate 41 to move smoothly and fit against the surface of the pile foundation, achieving precise correction of the verticality of the pile foundation and guiding the pile foundation to sink vertically. When the verticality deviation of the pile foundation occurs, the arc plate 41 automatically adjusts its position for real-time correction. At the same time, multiple adjustment mechanisms 2 continuously ensure the condition of the sleeve 1, ensuring that the arc plate 41 can stably and accurately correct the verticality of the pile foundation, ultimately ensuring the verticality of the pile foundation and completing the precise correction.
