Precast piles are piles of various materials and various forms, such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles and the like, which are manufactured in factories or construction sites, and are driven, pressed or vibrated into the soil by pile sinking equipment.
In general, since the length of each pile does not reach the depth specified by the design, it is necessary to connect the prefabricated piles one by one and to continue to drive down until the pile is driven to the depth specified by the design.
The traditional piling process and equipment are that after a precast pile is lifted by a crane, a pile body is clamped by a hoop, and then the pile body is pressed into soil by hydraulic pressure. For example, in chinese patent publication No. CN110130345a, a static pile machine and a method for welding a pipe pile are disclosed in detail, and specifically, the static pile machine includes a frame and walking legs installed below the frame, a control tower, a hydraulic driving part, a counterweight and a crane are provided on the frame, an alignment hole through which a pile section of the pipe pile passes is provided on the frame, and a hoop for hooping the pile section is provided on the hydraulic driving part; the static pressure pile machine further comprises an upper welding assembly and a lower welding assembly, wherein the upper welding assembly comprises a first wire and a fixed pulley positioned at the top of a crane mast, the first wire bypasses the fixed pulley, and an upper magnetic head for adsorbing a lower end plate of an upper pile section is arranged at the free end of the first wire; the lower welding assembly comprises a second lead and a mechanical arm, wherein the free end of the second lead is provided with a lower magnetic head for adsorbing an upper end plate of the lower pile section, the mechanical arm comprises a horizontal driving cylinder and a pneumatic finger for clamping the lower magnetic head, and a piston rod of the horizontal driving cylinder is connected with a fixing part of the pneumatic finger.

However, the traditional process equipment is low in construction efficiency because of repeated lifting and pressing of loose clamps, and the pile body is easy to deflect after loosening under the condition of loose soil.

The utility model is further described below with reference to the drawings and specific examples. Those of ordinary skill in the art will be able to implement the utility model based on these descriptions. In addition, the embodiments of the present utility model referred to in the following description are typically only some, but not all, embodiments of the present utility model. Therefore, all other embodiments, which can be made by one of ordinary skill in the art without undue burden, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
As shown in fig. 1-3, the precast pile driver is provided with a crane 1 for hoisting precast piles and a pile pressing mechanism for continuously pressing the precast piles into the soil, the pile pressing mechanism comprises a frame 2, the frame 2 is arranged in a separated mode, a certain space is reserved below the frame 2, equipment and personnel can enter the frame 2 for pile splicing, a hole is reserved in the middle of the frame 2, the crane 1 can place the precast piles on the ground, two symmetrically distributed lifting clamping mechanisms 3 are arranged on the frame 2 around the hole, and after the precast piles are grounded, the two lifting clamping mechanisms 3 can alternately work to clamp the precast piles and then press the precast piles into the soil.
As shown in fig. 3, the lifting and clamping mechanism 3 includes a lifting mechanism 31 and a clamping mechanism 32, the lifting mechanism 31 includes two vertical guide rails 311 distributed at intervals, the vertical guide rails 311 are provided with sliding blocks in sliding fit with the vertical guide rails 311, a lifting plate 312 is fixed between the sliding blocks of the two vertical guide rails 311, a fixing plate 313 is installed on the top of the vertical guide rails 311, a hydraulic lifting cylinder 314 is installed between the fixing plate 313 and the lifting plate 312, the clamping mechanism 32 is fixed on the lifting plate 312, and the clamping mechanism 32 can lift along the vertical guide rails 311 under the driving of the hydraulic lifting cylinder 314. After the precast pile is clamped by the clamping mechanism 32, the precast pile can be pressed into the soil by the clamping mechanism 32 being lowered.
As a preferred embodiment, the clamping mechanism 32 includes two pairs of transverse guide rails 321 installed on the lifting plate 312 at intervals, the transverse guide rails 321 are provided with sliding blocks in sliding fit with the transverse guide rails, clamping jaws 4 are installed on the sliding blocks of the two pairs of transverse guide rails 321, two clamping jaw hydraulic driving cylinders 322 are installed on the lifting plate 312, the two clamping jaw hydraulic driving cylinders 322 are arranged corresponding to the two clamping jaws 4, and can drive the two clamping jaws 4 to do opposite or opposite movement on the transverse guide rails 321 to achieve clamping. The clamping jaw 4 structure of the linear movement tensioning clamp is more suitable for the scheme compared with the clamping jaw 4 structure of the two clamping jaw rotating tensioning clamp, because the two lifting clamping mechanisms 3 work alternately, and the clamping jaw 4 structure of the linear movement tensioning clamp can pass through the other clamping jaw 4 in a staggered manner more easily.
As a preferred embodiment, a rotating rod 323 is disposed between two pairs of transverse guide rails 321, the middle of the rotating rod 323 is pivoted on the lifting plate 312, two ends of the rotating rod 323 are respectively pivoted with a transmission rod 324, and two transmission rods 324 are respectively pivoted on one clamping jaw 4. The rotating rod 323 and the two transmission rods 324 have the functions that when any one clamping jaw 4 moves, the rotating rod 323 can be pulled to rotate through the transmission rods 324, and then the other transmission rod 324 is driven to move through the rotating rod 323, so that the other clamping jaw 4 is driven to move. Advantageously, this way the two jaw hydraulic drive cylinders 322 can be reduced to one, i.e. only one jaw 4 hydraulic cylinder is required to drive one jaw 4 to move both jaws 4 simultaneously. And the centering clamp has the greatest advantage of centering and clamping and automatically aligning. Ensuring that the precast pile cannot horizontally displace when the two lifting clamping mechanisms 3 alternately clamp. Of course, this function could be achieved by synchronizing only the two jaw hydraulic drive cylinders 322 without such a design, but such a design would be structurally more reliable for achieving the alignment function than just the electronically controlled jaw 4 hydraulic drive. For example, it is also possible to control the combination of the two clamping jaws 4 with hydraulic cylinders and the rotary lever 323 plus the drive lever 324.
As a preferred embodiment, the clamping jaw 4 comprises a sliding table 41 fixedly connected with a sliding block on the transverse guide rail 321, a transmission rod 324 and a clamping jaw hydraulic driving cylinder 322 are connected with the sliding table 41, and a clamping arm 42 extending outwards linearly is arranged on the sliding table 41. The use of a linearly extending clamping arm 42 is also provided to facilitate the misuse of the other clamping jaw 4 during alternate operation.
In a preferred embodiment, the opposite sides of the two clamping arms 42 are provided with a friction-increasing contact portion 43, which may be plastic, rubber, or the like.
While the utility model has been described in terms of embodiments, it will be appreciated by those skilled in the art that the utility model is not limited thereto but rather includes the drawings and the description of the embodiments above. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
