[0002] The static pressure pile planting device is an important component of a pile planting integrated pile driver. Using a single pile planting integrated pile driver can complete drilling and pile planting, which is beneficial to improving the coaxiality during pipe pile planting and drilling and enhancing the pile planting efficiency. The static pressure pile planting device mainly includes a frame, a lifting seat, clamping blocks, a horizontal driving member for driving the clamping blocks to clamp or release the pipe fittings, and a lifting driving member for driving the lifting seat to move up and down for static pressure pile planting. A clamping channel for the insertion of pipe fittings is provided in the middle of the lifting seat. The clamping blocks are movably arranged inside the clamping channel. The horizontal driving member is arranged on the lifting seat and its driving shaft is fixedly connected to the clamping blocks. The lifting driving member is arranged on the frame and its driving shaft is connected to the lifting seat.

[0003] The pipe fittings need to be hoisted by a crane to the middle of several clamping blocks. During the hoisting and moving process, the pipe fittings are prone to shaking and deviating from the clamping center of the clamping blocks. If the pipe fittings collide with the clamping blocks during the descending process, the clamping blocks can buffer and reduce the impact force transmitted to the lifting seat and the frame. If they collide with the lifting seat, the impact force will directly act on the lifting seat, causing the lifting seat to collide and vibrate with the frame, affecting the service life of the static pressure pile planting device.

[0004] To solve the above problems, this case is thus generated. Content of the Utility Model

[0005] Therefore, in view of the above problems, the utility model provides a static pressure pile planting device.

[0006] To solve the above technical problems, the solution adopted by the utility model is: a static pressure pile planting device, including a frame, a lifting seat, and at least two clamping blocks. The lifting seat is movably arranged inside the frame. A clamping channel for the insertion of external pipe fittings is provided in the middle of the lifting seat. The clamping blocks are movably arranged inside the clamping channel. A horizontal driving member for respectively driving the clamping blocks to clamp or release the pipe fittings is arranged on the lifting seat. A lifting driving member for driving the lifting seat to lift and plant piles is arranged on the frame. At least four buffer members for buffering the impact force of external pipe fittings are evenly distributed along the periphery of the upper port of the clamping channel on the upper surface of the lifting seat;

[0007] The buffer member includes a pressing piece, a movable block, a fixed sleeve, an adjusting block, and a buffer spring. The fixed sleeve is fixedly arranged on the lifting seat towards the center of the clamping channel. The adjusting block is slidably inserted into the fixed sleeve. A sliding channel penetrating the inner end face is formed inside the adjusting block. The movable block is slidably inserted into the sliding channel. The buffer spring is arranged in the sliding channel. The inner end of the buffer spring abuts against the outer end face of the movable block, and the outer end abuts against the bottom of the sliding channel. At least two first connection and adjustment holes are symmetrically formed on both side faces of the fixed sleeve. At least two second connection and adjustment holes communicating with the sliding channel are symmetrically formed on both side faces of the adjusting block. A connecting bolt is detachably inserted between the fixed sleeve and the adjusting block. The connecting bolt is simultaneously inserted into the first connection and adjustment hole and the second connection and adjustment hole. A locking nut is arranged outside the connecting bolt. A buffer sliding groove for the connecting bolt to pass through and enabling the movable block to slide and press the buffer spring relative to the connecting bolt is formed on the movable block along the direction perpendicular to the connecting bolt. The inner end of the movable block extends towards the clamping channel. The pressing piece is fixedly arranged on the inner end face of the movable block.

[0008] Further improvement: An outwardly inclined guiding surface is provided at the upper end of the pressing piece.

[0009] Further improvement: The horizontal driving member is a first air cylinder or a first oil cylinder.

[0011] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows: In this case, the buffer member is provided to replace the impact of the lifting seat by the pipe fitting. The buffer member buffers the impact force of the pipe fitting. The pipe fitting presses the pressing piece, driving the movable block to slide along the sliding channel inside the adjusting block, squeezing the buffer spring in the sliding channel to balance the impact force, avoiding the situation of component damage of the static pressure pipe pile driving device under the long-term impact and vibration of the pipe fitting, being beneficial to protecting the lifting seat and the frame, extending the service life of the equipment, and converting the impact force into a boosting force that pushes the pipe fitting towards the center of the clamp in the reverse direction, which can not only protect the lifting seat but also assist the pipe fitting to enter the clamping center of the clamping block.

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Referring to Figures 1 to 4 , what is disclosed in the embodiment of the present utility model is a static - pressure pile - driving device, including a frame 10, a lifting seat 11, and eight clamping blocks 12. The lifting seat 11 is movably arranged inside the frame 10. A clamping channel 14 for inserting an external pipe fitting is provided in the middle of the lifting seat 11. The eight clamping blocks 12 are divided into upper and lower layers and are equidistantly arranged inside the clamping channel 14 in the same layer. A horizontal driving member 15 for respectively driving the clamping blocks 12 to clamp or release the pipe fitting is arranged on the lifting seat 11. A lifting driving member 16 for driving the lifting seat 11 to lift and drive the pile is arranged on the frame 10. Four buffer members 17 for buffering the impact force of the external pipe fitting are evenly distributed along the circumference of the upper port of the clamping channel 14 on the upper surface of the lifting seat 11.

[0018] The buffer member 17 includes a butting piece 18, a movable block 19, a fixed sleeve 20, an adjusting block 21, and a buffer spring 22. The fixed sleeve 20 is fixedly welded to the lifting seat 11 toward the center of the clamping channel 14. The adjusting block 21 is slidably inserted into the fixed sleeve 20. A sliding channel 13 is formed inside the adjusting block 21 and penetrates the inner end face. The movable block 19 is slidably inserted into the sliding channel 13. The buffer spring 22 is arranged in the sliding channel 13. The inner end of the buffer spring 22 abuts against the outer end face of the movable block 19, and the outer end abuts against the bottom of the sliding channel 13. Three first connection and adjustment holes 23 are symmetrically formed on both side faces of the fixed sleeve 20. Three second connection and adjustment holes 24 communicating with the sliding channel 13 are symmetrically formed on both side faces of the adjusting block 21. A connection bolt 25 is detachably inserted between the fixed sleeve 20 and the adjusting block 21. The connection bolt 25 is simultaneously inserted into the first connection and adjustment hole 23 and the second connection and adjustment hole 24. A locknut 26 is arranged outside the connection bolt 25. A buffer sliding groove 27 is formed on the movable block 19 along the direction perpendicular to the connection bolt 25 for the connection bolt 25 to pass through and enabling the movable block 19 to slide relative to the connection bolt 25 to compress the buffer spring 22. The inner end of the movable block 19 extends toward the clamping channel 14. The butting piece 18 is fixedly welded to the inner end face of the movable block 19. A guiding surface 28 is arranged at the upper end of the butting piece 18 and is inclined outward to guide the pipe fitting to move toward the center of the clamping channel 14. Under the abutment of the buffer spring, the connection bolt 25 abuts against the outer side wall of the buffer sliding groove 27. The maximum buffer stroke of the buffer sliding of the movable block 19 is affected by the distance between the butting piece 18 and the inner end face of the fixed sleeve 20. The distance between the butting piece 18 and the inner end face of the fixed sleeve 20 is adjusted by adjusting the connection position of the connection bolt 25 and the three first connection and adjustment holes 23. The buffer force is changed by using buffer springs 22 with different elastic coefficients.

[0019] The horizontal driving member 15 is a first air cylinder or a first oil cylinder. The cylinder body of the first air cylinder or the first oil cylinder is fixedly arranged on the lifting seat 11. The clamping block 12 is fixedly arranged on the piston rod of the first air cylinder or the first oil cylinder.

[0020] The lifting driving member 16 is four second air cylinders or four second oil cylinders. The second air cylinders or the second oil cylinders are arranged in pairs on a pair of sides of the lifting seat 11 and are arranged on the frame 10. The cylinder body of the second air cylinder or the second oil cylinder is fixedly arranged on the frame 10. The piston rod of the second air cylinder or the second oil cylinder is arranged on the lifting seat 11.

[0021] A method for using a static pressure pile driving device: The crane drops the pipe fitting into the frame 10 above the lifting seat 11 and then slowly descends. Manual assistance is used to adjust the position of the pipe fitting. After the pipe fitting enters between the four clamping blocks 12, the piston rod of the first cylinder or the first oil cylinder drives the clamping blocks 12 to clamp the pipe fitting. The piston rod of the second cylinder or the second oil cylinder drives the lifting seat 11 to descend, and the clamped pipe fitting is pressed into the drill hole. The piston rod of the first cylinder or the first oil cylinder drives the clamping blocks 12 to release the pipe fitting. The piston rod of the second cylinder or the second oil cylinder drives the lifting seat 11 to rise. The piston rod of the first cylinder or the first oil cylinder drives the clamping blocks 12 to clamp the pipe fitting again. The piston rod of the second cylinder or the second oil cylinder drives the lifting seat 11 to descend, and the clamped pipe fitting is further pressed into the drill hole, and the operation is repeated until the pipe fitting is completely pressed into the drill hole, and then the next pipe fitting is loaded and dropped.

[0022] During the process of the pipe fitting descending and being clamped, if the pipe fitting deviates from the clamping center and impacts the lifting seat 11 obliquely, the buffer member 17 buffers the impact force of the pipe fitting. The pipe fitting presses against the abutting piece 18, driving the movable block 19 to slide along the sliding channel 13 in the adjusting block 21, and compressing the buffer spring 22 in the sliding channel 13, so as to balance the impact force with the piece and convert the impact force into a boosting force that pushes the pipe fitting towards the clamping center in the reverse direction, which can not only protect the lifting seat 11 but also assist the pipe fitting to enter the clamping center of the clamping blocks 12.
