[0002] A pipe pile is a cylindrical hollow concrete component produced by a prestressed method and is commonly used in foundation treatment projects. Its main function is to increase the bearing capacity of the foundation and transfer the foundation load to the bearing layer.

Due to the long length of the pipe piles, the lifting height of the crane is high, so the lifting stability is poor. In the event of strong winds, it is easy to cause the pipe piles to shake randomly, making it difficult to carry out docking work and posing a safety risk to the operators. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 A pile driver for pipe pile construction includes a pile driver body 1, which is a hydraulic static pressure pile driver. A pile delivery area is provided at the front end of the pile driver body 1. A bottom support component 2 is provided on the pile driver body 1 near the pile delivery area. The bottom support component 2 is aligned with the pile delivery area in a horizontal state. A pile erection component 4 is provided on the pile driver body 1 away from the bottom support component 2. A support component 3 is provided at the top of the pile erection component 4. Prefabricated pipe piles 7 are provided on the bottom support component 2 and the support component 3.

[0025] The pile erecting component 4 includes a moving frame 401 and a jacking hydraulic rod 403. The bottom end of the jacking hydraulic rod 403 is hinged to the moving frame 401, and the top end of the jacking hydraulic rod 403 is hinged to the supporting component 3. The internal thread of the moving frame 401 is matched with a threaded rod 406. The threaded rod 406 is rotatably connected to the pile driver body 1, and one end of the threaded rod 406 is provided with a motor 404. The two ends of the moving frame 401 are rotatably connected to rollers 402. The rollers 402 are slidably connected to rails 405. The rails 405 are fixedly connected to the pile driver body 1.

[0026] In the present invention, a threaded rod 406 and a jacking hydraulic rod 403 are provided. The jacking hydraulic rod 403 can directly prop up the prefabricated pipe pile 7 by using the supporting component 3, thereby achieving the purpose of jacking the prefabricated pipe pile 7. The threaded rod 406 can drive the moving frame 401 threadedly matched with it to move by rotation, and the moving frame 401 will drive the jacking hydraulic rod 403 hinged thereto to move forward, so that the starting point of the jacking hydraulic rod 403 gradually approaches the bottom end of the prefabricated pipe pile 7, thereby increasing the angle between the jacking hydraulic rod 403 and the pile driving machine body 1, thereby achieving the purpose of increasing its stroke without increasing the length of the jacking hydraulic rod 403. On the one hand, the size of the pile erection component 4 is shortened, and on the other hand, the cost of large hydraulic rod equipment is reduced.

[0027] In addition, when further explanation is needed, the moving frame 401 uses rollers 402 at both ends to roll in the track 405, which can reduce the friction when the moving frame 401 moves. At the same time, the rollers 402 are solid wheel pairs, so that they can withstand the gravity of the prefabricated pipe piles 7.

[0028] The bottom support component 2 includes a rotating shaft 201, a propulsion hydraulic rod 202 and a rotating frame 203. The rotating shaft 201 is fixedly connected to the pile driver body 1, and the rotating frame 203 is rotatably connected to the rotating shaft 201. The propulsion hydraulic rod 202 is hinged at the bottom end of the rotating frame 203, and the propulsion hydraulic rod 202 is hinged to the pile driver body 1. A fixing ring 204 is provided on the rotating frame 203.

[0029] By providing a rotating frame 203 and a propulsion hydraulic rod 202, the rotating frame 203 is connected to the pile driver body by means of a rotating shaft 201, so that the rotating frame 203 can rotate stably, and when the rotating frame 203 drives the fixed ring 204 to rotate in a horizontal state, it will be consistent with the pile delivery area of ​​the pile driver state, so as to achieve the purpose of rapid positioning. In addition, the propulsion hydraulic rod 202 can be used to control the movement of the rotating frame 203, so that when the rotating frame 203 drives the fixed ring 204 to be horizontal, it can bear the weight of the prefabricated pipe pile 7.

[0030] The inner diameter of the fixing ring 204 is larger than the diameter of the prefabricated pipe pile 7. The fixing ring 204 is provided with a support bolt 205. The support bolt 205 is supported on the end face of the prefabricated pipe pile 7 after being tightened.

[0031] By providing the support bolts 205 , the support bolts 205 can support the prefabricated pipe pile 7 after being screwed into the fixing ring 204 , thereby preventing the prefabricated pipe pile 7 from sliding downward during the erection process.

[0032] The supporting component 3 includes a movable bracket 301. The two sides of the movable bracket 301 are provided with pins 302 hinged to the jacking hydraulic rod 403. The upper end surface of the movable bracket 301 is provided with an arc surface that fits the prefabricated pipe pile 7, and the arc surface is provided with an anti-slip rubber pad;

[0033] By setting up the movable bracket 301, the movable bracket 301 can fit with the prefabricated pipe pile 7, and the provided rubber pad is used to increase the friction between the two, thereby avoiding the problem of sliding between the movable bracket 301 and the prefabricated pipe pile 7 during the jacking process, and at the same time protecting the prefabricated pipe pile 7 to avoid damage caused by collision, extrusion, etc.

[0034] Two clamping hydraulic rods 303 are respectively provided on the movable bracket 301. The output direction of the two clamping hydraulic rods 303 is toward the prefabricated pipe pile 7. The output ends of the clamping hydraulic rods 303 are each provided with an anti-slip clamping block 304. The contact surface between the anti-slip clamping block 304 and the prefabricated pipe pile 7 is made of rubber.

[0035] By providing a clamping hydraulic rod 303 and an anti-slip clamp 304, the clamping hydraulic rod 303 and the anti-slip clamp 304 can further improve the firmness of the connection between the support component 3 and the prefabricated pipe pile 7, further avoiding the problem of slipping, and at the same time can hold the prefabricated pipe pile 7 tightly, avoiding the problem of the prefabricated pipe pile 7 being disturbed by airflow during the erection process and shaking.

[0036] A fixed bracket 5 is provided on the pile driving machine body 1 at a position corresponding to the prefabricated pipe pile 7. The fixed bracket 5 is used to position and support the prefabricated pipe pile 7, and a roller is provided on the fixed bracket 5 whose rolling direction is consistent with the placement direction of the prefabricated pipe pile 7.

[0037] By setting up the fixed bracket 5, the fixed bracket 5 can support and store the prefabricated pipe pile 7, and bear the prefabricated pipe pile 7 in the non-piling stage, thereby reducing the pressure on the pile erecting component 4. At the same time, the fixed bracket 5 can facilitate the sliding of the prefabricated pipe pile 7 by using the provided rollers, thereby facilitating the positioning and fixing of the prefabricated pipe pile 7 and the base component 2.

[0038] Two hydraulic legs 6 are provided at one end of the pile driver body 1 close to the pile erecting component 4. The two hydraulic legs 6 are driven independently, and foot pads are provided under the hydraulic legs 6 to increase the ground contact area.

[0039] By setting up the hydraulic support legs 6, the hydraulic support legs 6 can fit into the ground, adjust the pile driver body 1 to a horizontal state, and transmit the force applied by the pile erecting component 4 during operation to the ground, thereby avoiding the problem of the center of gravity being too far outward during pile erection, causing the equipment to tilt.

[0040] Working principle:

[0041] The prefabricated pipe pile 7 is placed on the fixed bracket 5 and connected to the fixing ring 204 on the bottom supporting part 2. Then, the hydraulic rod 303 is clamped to drive the anti-slip clamping block 304 to fix the prefabricated pipe pile 7. The jacking hydraulic rod 403 lifts the prefabricated pipe pile 7 through the movable bracket 301. At the same time, the hydraulic rod 202 is pushed to drive the fixing ring 204 to move through the rotating frame 203. The prefabricated pipe pile 7 rotates upward with the rotating shaft 201 as the center under the positioning of the fixing ring 204 and the supporting bolt 205. At the same time, the motor 404 drives the moving frame 401 to move toward the bottom supporting part 2 through the threaded rod 406. The moving frame 401 moves in the track 405 using the roller 402. When the moving frame 401 moves, it drives the jacking hydraulic rod 403 to move at the same time, so that the angle between the jacking hydraulic rod 403 and the pile driver body increases.

[0042] After the prefabricated pipe pile 7 is erected, the pile driving machine body 1 fixes the prefabricated pipe pile 7 and then loosens the support bolts 205 so that the prefabricated pipe pile 7 can move downward smoothly. After the prefabricated pipe pile 7 is pressed and sent, the bottom supporting component 2 is reset.

[0043] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications based on the present invention that solve essentially the same technical problems and achieve essentially the same technical effects are included within the scope of protection of the present invention.
