[0031] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0032] The combined pile driver for ultra-deep negative hole construction method piles proposed in the embodiment of the utility model directly connects the driving and pulling machine with the connecting clamp so that the driving and pulling machine can control the pile-reversing system and the pile-delivering system to work. During the pile-reversing process, the driving and pulling machine can control the pile cap to be in an inclined state so that the notch is located on the upper side, and then one end of the pipe pile is directly shoveled into the notch, and then the pile cap is lifted and shoveled in continuously, so that one end of the pipe pile can be directly inserted into the limiting hole. At this time, the pipe pile can be straightened, and when the pile is delivered by the pile delivery system, the opening size of the entire limiting hole becomes larger due to the opening of the notch, so that one end of the pipe pile can be more easily inserted into the limiting hole, thereby making the pile-reversing and pile-delivering process more convenient.
[0033] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0034] Reference Figure 1 and Figure 2A combined pile driver for ultra-deep negative hole construction piles includes a pile driving system 1 and a pile driving system 2. Both the pile driving system 1 and the pile driving system 2 include a connecting chuck 3 and a pile cap 4. The pile driving system 2 also includes a force transmission rod 5.
[0035] The connection clamp 3 and the pile cap 4 in the pile-inverting system 1 are detachably connected, the connection clamp 3, the force transmission rod 5 and the pile cap 4 in the pile-delivering system 2 are connected in sequence, and the two ends of the force transmission rod 5 in the delivery system are detachably connected to the connection clamp 3 and the pile cap 4 respectively by bolts. This makes it more convenient for the inverting system and the pile-delivering system 2 to be disassembled for transportation.
[0036] See also Figure 1 and Figure 3 The connecting chuck 3 includes a fixture plate 31 directly connected to the pulling machine, a support plate 32 vertically welded to both side ends of the fixture plate 31, and a connecting plate 33 vertically welded to the fixture plate 31 and the lower ends of the two support plates 32. The pile cap 4 is detachably connected to the connecting plate 33.
[0037] The connection plate 33 is provided with multiple groups of connection holes 331, each group of connection holes 331 includes multiple groups of connection holes 331 evenly spaced in the circumferential direction, and the multiple groups of connection holes 331 are distributed from the inside to the outside along the diameter direction of the connection plate 33. The end of the pile cap 4 close to the connection plate 33 is evenly spaced in the circumferential direction to form a circle of threaded holes 41 aligned with a group of connection holes 331, and the connection plate 33 and any circle of connection holes 331 are inserted into the connection bolts 332 threadedly connected to the threaded holes 41. The connection bolts 332 can pass through different groups of connection holes 331 and then be threadedly connected to pile caps 4 with different diameters, thereby completing the replacement of different pile caps 4, and at the same time, the pile cap 4 that is more suitable for pile inversion can be selected according to the diameter of the pipe pile, thereby making the pile inversion process more convenient.
[0038] A plurality of grooves 311 are provided at both end surfaces of the clamp plate 31. Anti-slip rubber strips 312 are embedded in the grooves 311 of the clamp plate 31. The anti-slip rubber strips 312 protrude from the two end surfaces of the clamp plate 31. The grooves 311 include long grooves 3111 provided along the length direction of the clamp plate 31 and wide grooves 3112 provided along the width direction of the clamp plate 31. A plurality of adjacent long grooves 3111 form a group, and a plurality of adjacent wide grooves 3112 form a group. The opening directions of the two adjacent groups of grooves 311 are different. When the working end of the driving and pulling machine clamps the clamp plate 31, the anti-skid rubber strip 312 will be compressed and deformed, thereby increasing the friction between the clamp plate 31 and the working end of the driving and pulling machine, thereby reducing the probability of unstable clamping of the connecting clamp 3 during the operation of the driving and pulling machine, and improving the stability during pile inversion and pile delivery. The groove 311 is set as a long groove 3111 and a wide groove 3112, and the two grooves are staggered, so that the anti-skid rubber strip 312 can provide friction along the length direction, width direction and rotation reverse direction of the clamp plate 31, thereby further improving the clamping stability.
[0039] The connecting chuck 3 also includes an ear hook 34 welded to the end of the support plate 32 away from the clamp plate 31, and a lifting hole 341 for external lifting is opened in the middle of the ear hook 34. On the one hand, it is convenient to carry the pile driving system 1 or the pile delivery system 2, and on the other hand, when the connecting chuck 3 is clamped by the driving and pulling machine, it can be safely connected through the wire rope and the hook. When the clamping is disconnected, it can also ensure that the pile driving system 1 or the pile delivery system 2 will not fall directly to the ground, which is safer.
[0040] A limiting hole 42 for inserting a pipe pile is provided at the lower end of the pile cap 4, and a notch 43 is provided on one side of the opening of the limiting hole 42. The maximum opening of the notch 43 is the same diameter as the limiting hole 42. During the pile driving process, the pile cap 4 can be controlled by the driving and pulling machine to be in an inclined state so that the notch 43 is located on the upper side, and then one end of the pipe pile is directly shoveled into the notch 43, and then the pile cap 4 is lifted and shoveled in continuously, so that one end of the pipe pile can be directly inserted into the limiting hole 42. When the pile is delivered, the opening of the notch 43 makes the opening size of the entire limiting hole 42 larger, so that one end of the pipe pile can be inserted into the limiting hole 42 more easily.
[0041] The pile cap 4 has balls 44 arranged in an array on the inner wall of the limiting hole 42. When one end of the pile is inserted into the notch 43, it can contact the balls 44 and then be inserted into the limiting hole 42 more smoothly.
