Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for flat pile driving. Background Technology

[0002] Static cone penetration test involves pressing a pile foundation probe into the soil at a certain rate using static pressure, measuring its penetration resistance, and dividing the soil into layers according to the magnitude of the resistance to determine the engineering properties of the soil. The commonly used auxiliary equipment is a pile driver, which can press the pile foundation into the soil. The clamping device of the pile driver plays a role in stabilizing and positioning the pile foundation.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221545607U) discloses a static pressure pile driver square pile clamp, comprising: a platform with four symmetrically arranged sliding grooves along its diagonal; a rotating panel above the platform; sliders slidably connected to the platform and fitting into the sliding grooves; clamping plates fixedly connected to the bottom of the sliders; connecting blocks rotatably connected to the surface of the sliders; the other end of the connecting blocks rotatably connected to the bottom of the rotating panel; a fixed hinge seat fixedly connected to one end of the slider; a first connecting column fixedly connected to the fixed hinge seat; and symmetrical fixing blocks fixedly connected to both sides of the slider at the other end of the diagonal. This utility model can drive the four sliders to move within the sliding grooves via a cylinder, causing the clamping plates fixedly connected below the sliders to move synchronously. The four clamping plates can apply the same magnitude of force to the four sides of the square pile for balanced clamping. The entire device is simple to operate, convenient to use, and highly accurate.

[0004] Although the aforementioned patent can achieve synchronous displacement of the four clamping plates, it can only clamp and position square piles with square structures when clamping pile foundations. It cannot clamp and position flat piles with rectangular structures, which makes its clamping somewhat limited and unable to adapt to clamping and fixing quadrilateral pile foundations of different shapes.

[0005] Therefore, this utility model provides a clamping device for flat pile driving to solve the above problems. Utility Model Content

[0028] 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.

[0029] like Figure 1-5As shown, this utility model provides a clamping device for flat pile driving, including a support assembly 1, which includes a platform 11 with a guide groove 12. A guide frame 13 is slidably connected inside the guide groove 12, and a sliding plate 14 is fixedly connected to the upper surface of the guide frame 13. A drive assembly 2 is positioned above the platform 11, and its pulling end is fixedly connected to the sliding plate 14. The drive assembly 2 is used for synchronous pulling control of the sliding plate 14. A clamping assembly 3 includes a hydraulic pipe 31, with hydraulic cylinders 32 fixedly connected to both ends of the hydraulic pipe 31. A cylinder cover 33 is sealed to the other end of the hydraulic cylinder 32, and a piston rod 3 is slidably connected inside the cylinder cover 33. 4. A clamping plate 35 is fixedly connected to the other end of the piston rod 34, and a guide frame 13 is fixedly connected to the outer wall of the hydraulic cylinder 32. The sliding plate 14 is driven to move synchronously by the drive assembly 2. When the sliding plate 14 moves, the hydraulic cylinder 32 is driven to move synchronously by the bottom guide frame 13. When the clamping plate 35 on one axis clamps and contacts the outer wall of the flat pile, it continues to clamp, causing the piston rod 34 on that side to retract. In the retracted state, the hydraulic oil inside the hydraulic cylinder 32 is pushed, thereby realizing the extension of the piston rod 34 on the other side. When the clamping plate 35 on that side clamps and contacts the other axis of the flat pile, the four sides of the flat pile are stably clamped and fixed, thus realizing the clamping and fixing of the rectangular flat pile.

[0030] Furthermore, a guide rail 16 is fixedly connected to the upper surface of the platform 11, and a slider 15 is slidably connected above the guide rail 16. A slide plate 14 is fixedly connected to the upper surface of the slider 15. Two sliders 15 and guide rails 16 are symmetrically arranged below each slide plate 14. The arrangement of sliders 15 and guide rails 16 provides good support for the slide plate 14, improves the load capacity of the slide plate 14, and provides good guiding and sliding function for the slide plate 14.

[0031] Furthermore, the drive assembly 2 includes a support frame 25, which is fixedly connected to the upper surface of the platform 11. A servo motor 21 is fixedly connected to the upper surface of the support frame 25. A rotating disk 22 is fixedly connected to the output end of the servo motor 21. A hinge rod 23 is hinged to each corner of the rotating disk 22. A hinge seat 24 is hinged to the other end of the hinge rod 23. The hinge seat 24 is the pulling end of the drive assembly 2. The rotating disk 22 is driven to rotate by the rotation of the servo motor 21. While the rotating disk 22 is rotating, the hinge seat 24 is pulled by the hinge rod 23. Thus, the sliding disk 14 is pulled and displaced by the fixed connection between the hinge seat 24 and the sliding plate 14.

[0032] Furthermore, the output end of the servo motor 21 is rotatably connected to the central sleeve of the support frame 25 via a bearing, and the hinge rod 23 has an L-shaped structure. Both the hinge rod 23 and the slide plate 14 have four evenly distributed around their circumference.

[0033] Furthermore, the hydraulic cylinder 32 has two through holes inside the end located below the platform 11, which are adapted for the installation of the hydraulic cylinder 32. The hydraulic cylinder 32 is fixedly connected to the inner wall of the through hole. Two piston rods 34 are fixedly connected to the outer wall of each clamping plate 35. There are two sets of clamping components 3, and the two sets of clamping components 3 are diagonally distributed. Each set of clamping components 3 is equipped with two hydraulic cylinders 32 and clamping plates 35. The connection structure between the two hydraulic cylinders 32 and clamping plates 35 is the same. By having the clamping plates 35 contact the outer wall of the flat pile, the clamping contact area can be increased. In turn, the stability and firmness of the flat pile clamping are improved by increasing the friction.

[0034] Working principle: First, the support component 1 is placed on the top of the flat pile, and then the servo motor 21 is driven. The servo motor 21 drives the rotating disk 22 to rotate. The hinge seat 24 is pulled and controlled by the hinge rod 23. The hinge seat 24 moves while driving the slide plate 14 to move. The slide plate 14 drives the hydraulic cylinder 32 to move through the bottom guide frame 13. When the clamping plate 35 on one axis is in contact with the outer wall of the flat pile, it is continuously clamped, causing the piston rod 34 on that side to retract. In the retracted state, the hydraulic oil inside the hydraulic cylinder 32 is pushed, thereby causing the piston rod 34 on the other side to extend. When the clamping plate 35 on that side is in contact with the other axis of the flat pile, the four sides of the flat pile are stably clamped and fixed, thus achieving the clamping and fixing of the rectangular flat pile. Then, in conjunction with the pile driver, the pile driving operation can be carried out.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
