Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a pile foundation pressing device. Background Technology

[0002] A deep foundation consisting of piles and pile caps connecting the tops of the piles, or a single-pile foundation consisting of a column and piles, is simply called a pile foundation. Pile foundation construction typically involves drilling holes first, then pouring cement into the holes, waiting for the cement to solidify, and finally placing the pile caps on top of the piles after multiple piles are installed to complete the construction.

[0003] In the current technology, pile foundations are usually installed by directly inserting the piles into pre-drilled holes. However, during the installation process, there is a common problem that the piles cannot be inserted. Therefore, a hammer is used to install the piles, but hammering can easily damage the piles. Utility Model Content

[0004] To address the problem that existing pile foundations typically involve directly inserting piles into pre-drilled holes, which can lead to situations where the piles cannot be fully inserted, a hammering method is often used. However, this hammering method can easily damage the piles. Therefore, this application provides a pile foundation pressing device.

[0005] A pile foundation pressing device includes a mounting frame for mounting on a pile embedding device. A guide frame is mounted on the mounting frame, perpendicular to the mounting frame. A clamping block is also mounted on the guide frame, slidably connected to the guide frame and capable of sliding along the vertical direction of the guide frame. A driving component is also mounted on the guide frame to drive the clamping block. A through clamping opening is provided on the clamping block, and a clamping element for clamping the pile foundation at the clamping opening is provided inside the clamping block.

[0006] By adopting the above technical solution, during the pile embedding process, the clamping block can first clamp the pile foundation and then push it downwards, then release the pile foundation, move the clamping block upwards, and then clamp the pile foundation again to continue pushing it upwards. By repeating the above movements, the pile foundation can be smoothly sent into the pit without hammering, reducing the possibility of pile foundation shifting or tilting during the pressing process, and improving construction efficiency and quality.

[0007] Optionally, the guide frame is disposed on both sides of the mounting frame, and the guide frame is provided with a sliding groove. The clamping block is embedded in the sliding groove and can slide along the sliding groove.

[0008] By adopting the above technical solution, the guide frame is set on both sides of the mounting frame, which makes the device more stable and balanced, preventing displacement or tilting due to uneven force during the pressing process. The guide frame is provided with a sliding groove, and the clamping block is embedded in the sliding groove and can slide along the sliding groove, ensuring the precise movement of the clamping block in the vertical direction and improving the accuracy and reliability of pile foundation pressing.

[0009] Optionally, the guide frame is further provided with a limiting seat, which is located at the top of the sliding groove. The limiting seat is fixedly connected to the guide frame and is used to abut against the clamping block.

[0010] By adopting the above technical solution, the limiting seat is set at the top of the sliding groove and fixedly connected to the guide frame, which can effectively prevent the clamping block from detaching from the guide frame when it moves upward, ensure that the clamping block slides stably along the predetermined path, and improve the safety and reliability of the device.

[0011] Optionally, the driving component includes a driving cylinder, and each of the two guide frames is provided with a driving cylinder. The driving cylinder is fixedly mounted on the limiting seat, and the piston rod of the driving cylinder passes through the limiting seat and is fixedly connected to the clamping block. The driving cylinder is used to drive the clamping block to move up and down along the guide frame.

[0012] By adopting the above technical solution, the installation of drive cylinders on both sides enables the clamping block to move stably and accurately up and down along the guide frame, improving the positioning accuracy and stability during the pile foundation pressing process. Simultaneously, the drive cylinders are fixed to the limit seats, ensuring the compactness and reliability of the structure, reducing the overall size of the equipment, and facilitating installation and maintenance.

[0013] Optionally, the clamping component includes a clamping cylinder and a clamping plate, wherein the clamping cylinder is embedded in the clamping block, and the clamping plate is fixedly connected to the piston rod of the clamping cylinder.

[0014] By adopting the above technical solutions, the combined design of the clamping cylinder and the clamping plate enables the pile foundation to be firmly clamped during the pressing process, improving the stability and safety of the pile foundation during the pressing process. The clamping cylinder is embedded in the clamping block, which can effectively transmit the driving force and ensure that the clamping force is evenly distributed. The clamping plate is fixedly connected to the piston rod of the clamping cylinder, which can accurately control the clamping position, further enhance the clamping effect, and prevent the pile foundation from shifting or falling off during the pressing process.

[0015] Optionally, the clamping plate is provided with a mating groove, which is configured to correspond to the shape of the pile foundation, and the pile foundation can be embedded in the mating groove.

[0016] By adopting the above technical solutions, the mating grooves on the clamping plate can accurately match the shape of the pile foundation, ensuring that the pile foundation will not shift or shake when clamped, thereby improving the stability and accuracy of the pile foundation pressing process, reducing the damage to the pile foundation caused by friction, and further improving the service life of the pile foundation.

[0017] Optionally, the clamping block is provided with a mating groove, the mating groove is configured to correspond to the shape of the guide frame, and the guide frame is embedded in the mating groove.

[0018] By adopting the above technical solution, a mating groove is provided on the clamping block, which is shaped to correspond to the guide frame, allowing the guide frame to be embedded within the groove. This ensures that the clamping block slides smoothly along the guide frame, improving the stability and accuracy of the device operation and reducing operational errors caused by shaking. Simultaneously, this design effectively prevents the clamping block from shifting or falling off during sliding, ensuring the safety of the pile foundation pressing process.

[0019] Optionally, the clamping block is provided with a guide wheel, the guide wheel is rotatably connected to the clamping block, the guide wheel is located next to the mating groove, and the guide wheel abuts against the guide frame.

[0020] By adopting the above technical solutions, the guide wheels on the clamping block can reduce the friction when the clamping block slides along the guide frame, improve the smoothness of sliding, thereby ensuring the stability and accuracy of the pile foundation during the pressing process. At the same time, the guide wheels also guide the movement of the clamping block, further improving the overall stability of the device.

[0021] Optionally, multiple guide wheels are provided beside the mating groove, the guide wheels are arranged around the mating groove and each guide wheel abuts against the guide frame.

[0022] By adopting the above technical solution, the guide wheels are arranged around the mating groove and abut against the guide frame, making the clamping block slide more stably and smoothly along the guide frame, reducing friction, and improving the service life and operational reliability of the device. At the same time, the design of multiple guide wheels effectively disperses the force, further enhancing the guiding accuracy and ensuring that the pile foundation maintains the accurate position and posture during the pressing process.

[0023] In summary, this application has at least the following beneficial effects: This application solves the problem that in the prior art, pile foundations are usually buried by directly inserting the piles into pre-drilled holes. However, during the burying process, the piles may not be able to be inserted. Therefore, the piles are buried by hammering. However, the hammering process can easily damage the piles. This application can clamp the piles and then continuously push the piles into the pit by moving them up and down, thus reducing the damage to the piles caused by hammering.

Clamping cylinder; 311. Clamping plate; 312. Mating groove; 32. Guide wheel; 33.

[0028] A pile foundation pressing device, such as Figure 1 and Figure 2 As shown, the device includes a mounting frame for mounting on a pile-laying device. A guide frame is mounted on the mounting frame, perpendicular to it. A clamping block is also mounted on the guide frame, slidably connected to it and capable of sliding along the vertical direction of the guide frame. A driving component is also mounted on the guide frame to drive the clamping block. The clamping block has a through-hole, and a clamping element is installed inside to hold the pile at the through-hole. In practice, when the pile is inserted, the clamping block, positioned at the top of the guide frame, clamps the pile. Moving the clamping block downwards allows the pile to be driven further in. When the clamping block reaches the bottom, it releases the pile and returns to the top of the guide frame to clamp it again, thus driving the pile further in and achieving pile installation.

[0029] like Figure 1 and Figure 2 As shown, guide frames are positioned on both sides of the mounting frame. Sliding grooves are formed on the guide frames, and the clamping blocks are embedded within these grooves and can slide along them. Limit seats are also provided on the guide frames, located at the top of the sliding grooves. The limit seats are fixedly connected to the guide frames and abut against the clamping blocks. In practice, the clamping blocks can move along the sliding grooves formed by the guide frames during vertical movement. When the clamping blocks reach the top, they are restricted by the limit seats, preventing further movement and reducing the likelihood of the clamping blocks detaching, thus improving stability during use.

[0030] like Figure 1 and Figure 2As shown, the driving component includes a driving cylinder. Each of the two guide frames is equipped with a driving cylinder, which is fixedly mounted on a limiting seat. The piston rod of the driving cylinder passes through the limiting seat and is fixedly connected to the clamping block. The driving cylinder is used to drive the clamping block to move up and down along the guide frame. In specific implementation, the piston rod of the driving cylinder can directly drive the clamping block, effectively moving it.

[0031] like Figure 2 and Figure 3 As shown, the clamping component includes a clamping cylinder and a clamping plate. The clamping cylinder is embedded within the clamping block, and the clamping plate is fixedly connected to the piston rod of the clamping cylinder. The clamping plate has a mating groove corresponding to the shape of the pile foundation, allowing the pile foundation to be embedded within it. In a specific implementation, the clamping cylinder and clamping plate are positioned on both sides of the clamping block, enabling the pile foundation to be clamped from both sides. Due to the corresponding shape of the mating groove, the pile foundation can be embedded within it, resulting in a more stable clamping. In other embodiments, clamping cylinders can be provided on all four sides of the clamping block to further improve the clamping effect.

[0032] like Figure 1 and Figure 2 As shown, the clamping block has a mating groove, which corresponds to the shape of the guide frame, and the guide frame is embedded in the mating groove. A guide wheel is provided on the clamping block, rotatably connected to it, and positioned next to the mating groove, abutting against the guide frame. Multiple guide wheels are arranged around the mating groove, each abutting against the guide frame. In specific implementation, the guide wheels are located on the upper and lower sides of the clamping block. The guide wheels reduce friction during the movement of the clamping block, making the insertion of the pile foundation smoother, and also guide the movement of the clamping block.

[0033] Working principle: When the pile is placed, the clamping block is located at the top of the guide frame and clamps the pile. The clamping block moves downward to send the pile downward. When the clamping block reaches the bottom, it releases the pile and returns to the top of the guide frame to clamp the pile again and send it downward. Repeating the above actions can realize the sending of the pile.

[0034] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
