Description

Technical Field

[0001] This utility model relates to the field of pile foundation operation technology, specifically to a pile extraction connection assembly for pile foundation operation. Background Technology

[0002] A deep foundation consisting of piles and pile caps connecting the pile tops, or a single-pile foundation consisting of a column connected to the pile foundation, is simply called a pile foundation. During pile foundation work, test piles or verification piles may be necessary to verify the bearing capacity and settlement performance of the pile foundation, which requires pile extraction operations.

[0003] However, current pile extraction equipment can only fix piles of specific specifications when performing pile extraction operations. Its applicable diameter range is relatively low, and the contact surface with the pipe pile is small, which reduces the pulling force squeezed by the pipe pile, thereby reducing the stability of the pile extraction and resulting in poor pile fixing effect. Utility Model Content

[0004] The present invention aims to provide a pile extraction connection component that can adapt to pile foundation operations that cannot be made of diameter and has good pile extraction stability.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a pile extraction connection assembly for pile foundation operation, including a connecting plate, a lower clamping platform is provided on the upper side of the connecting plate, a vertical hydraulic push rod is provided on the upper side of the lower clamping platform, and the telescopic end of the vertical hydraulic push rod is connected to the upper clamping platform; Both the lower clamping platform and the upper clamping platform include a fixed base. An annular component is integrally provided on the upper part of the fixed base. A top cover is installed on the upper side of the annular component by screws. A through hole is provided in the middle part of the top cover and the fixed base. A U-shaped seat is provided inside the fixed base. A horizontal hydraulic push rod is provided on the upper side of the U-shaped seat. An adjustment seat is connected to the output end of the horizontal hydraulic push rod. A clamping component is provided on the upper side of the adjustment seat. The clamping component includes a connecting block, with an arc-shaped clamping piece on the front side of the connecting block. The clamping component is fixedly installed on the adjusting seat by bolts, and ear seats are provided at the four corners of the connecting plate.

[0006] As a preferred embodiment of the above solution, the adjusting seat is provided with strip-shaped protrusions on both sides and the bottom, and the U-shaped seat is provided with strip-shaped grooves on both sides and the bottom, so that the adjusting seat and the U-shaped seat can be slidably connected by the cooperation of the strip-shaped protrusions and the strip-shaped grooves.

[0007] More preferably, there are 3-6 U-shaped seats evenly distributed on the fixed base.

[0008] More preferably, the clamping member is fixedly mounted on the adjusting seat by two bolts.

[0009] The beneficial effects of this utility model are as follows: A horizontal hydraulic push rod drives an adjusting seat, on which clamping components of different specifications can be flexibly installed. Since the clamping components are fixed to the fixing rod on the adjusting seat using a plug-in connection and limiting nut, suitable clamping components can be quickly replaced according to pile foundations of different diameters, greatly improving the adaptability to various pile foundation specifications. Simultaneously, the arc-shaped clamping plate increases the contact area with the pipe pile, effectively increasing the pile extraction force and enhancing the stability of pile extraction, ensuring smooth pile extraction operations and improving construction efficiency and quality. Furthermore, the vertical hydraulic push rod allows adjustment of the distance between the two clamping platforms and the clamping height to meet different construction needs.

[0016] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] like Figure 1-5 As shown, a pile extraction connection assembly for pile foundation operations includes a connecting plate 1. A lower clamping platform is disposed on the upper side of the connecting plate 1, and a vertical hydraulic push rod 2 is disposed on the upper side of the lower clamping platform. The telescopic end of the vertical hydraulic push rod 2 is connected to the upper clamping platform. The vertical hydraulic push rod 2 is disposed between the lower clamping platform and the upper clamping platform. The distance between the two clamping platforms can be adjusted by the vertical hydraulic push rod 2, thereby adjusting the clamping height to meet different construction needs.

[0018] Both the lower and upper clamping platforms include a fixed base 3. An annular component 4 is integrally formed on the upper part of the fixed base 3, and a top cover 5 is installed on the upper side of the annular component 4 by screws. The top cover 5 and the middle part of the fixed base 3 are provided with through holes. A U-shaped seat 6 is evenly distributed inside the fixed base 3. A horizontal hydraulic push rod 7 is provided on the upper side of the U-shaped seat 6. The output end of the horizontal hydraulic push rod 7 is connected to an adjusting seat 8. A clamping component is provided on the upper side of the adjusting seat 8.

[0019] The adjusting seat 8 has strip-shaped protrusions on both sides and the bottom, and the U-shaped seat 6 has strip-shaped grooves on both sides and the bottom. The adjusting seat 8 and the U-shaped seat 6 are slidably connected by the cooperation of the strip-shaped protrusions and the strip-shaped grooves.

[0020] The clamping component includes a connecting block 12, with an arc-shaped clamping piece 10 on the front side of the connecting block 12. The clamping component is fixedly mounted on the adjusting seat 8 by bolts 9. Ear seats 11 are provided at each of the four corners of the connecting plate 1.

[0021] When performing pile extraction, the component is first fixed to the pile extraction equipment by means of the lug 11. At the same time, the lower clamping platform and the upper clamping platform are sleeved on the outside of the pile foundation. The lower clamping platform and the upper clamping platform both include a fixing seat 3. An annular part 4 is integrally provided on the upper part of the fixing seat 3. A top cover 5 is installed on the upper side of the annular part 4 by screws. The fixing seat 3, the annular part 4 and the top cover 5 constitute a protective shell, which covers the arc-shaped clamping piece 10.

[0022] During pile extraction, the horizontal hydraulic push rod 7 inside the U-shaped seat 6 operates to push the adjusting seat 8 forward relative to the U-shaped seat 6, thereby driving the clamping component to clamp the outer wall of the pile foundation.

[0023] The surface of the arc-shaped clamping plate 10 is provided with a rough layer, which can increase the clamping effect of the pile foundation. Since the clamping part and the adjusting seat 8 are fixed by bolts 9, the appropriate clamping part can be quickly replaced according to the pile foundation of different diameters, which greatly improves the adaptability to pile foundations of various specifications, enhances the stability of pile extraction, ensures the smooth progress of pile extraction operation, and improves construction efficiency and quality.

[0024] 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.
