DETAILED DESCRIPTION

[0019] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a pile driver for construction engineering includes a protection box 1, the protection box 1 includes a top plate 11, a side plate 18 and a bottom plate 12, a plurality of universal wheels 14 are fixedly installed at the bottom of the bottom plate 12, a hammer mechanism 3 is fixedly arranged on the side of the top plate 11 away from the bottom plate 12; a lifting plate 13 is also arranged between the top plate 11 and the bottom plate 12; a slide groove 15 is opened on the side plate 18, and connecting blocks 17 are fixedly connected at both ends of the lifting plate 13, and the connecting blocks 17 pass through the slide groove 15, so that the lifting plate 13 can slide up and down along the slide groove 15 inside the protection box 1;

[0021] The protection box 1 is further provided with a plurality of springs 16, both ends of which are respectively fixedly connected to the bottom plate 12 and the lifting plate 13, and a clamping mechanism 2 is fixedly provided on the lifting plate 13 away from the bottom plate 12;

[0022] The hammer mechanism 3 includes a hoist 31 and a lifting frame 32, both of which are fixedly mounted on the top plate 11, and at least one support rod 33 is fixedly connected to the lifting frame 32 on the side away from the top plate 11, and a pulley 34 is provided on the support rod 33, and the pulley 34 is rotatably connected to the support rod 33 through a pin shaft, and the hammer mechanism 3 also includes a hammer 35 and a steel cable 36, one end of the steel cable 36 is fixedly connected to the hammer 35, and the other end is fixedly connected to the drum provided on the hoist 31 after being wound around the pulley 34; it should be noted that the hoist 31 and the hammer 35 are respectively provided on both sides of the lifting frame 32;

[0023] During operation, when the hammer mechanism 3 is working, the steel cable 36 is wound up by the drum provided on the winch 31, and the hammering object 35 is pulled up. When the hammering object 35 is pulled up to the set height, the winch 31 stops working and releases the steel cable 36. Due to the effect of gravity, the hammering object 35 falls vertically and hammers the pipe pile. The above process is repeated to achieve the purpose of continuous piling.

[0024] like Figure 4-Figure 5As shown, the clamping mechanism 2 includes a cylinder 21, a mounting frame 23 and two clamping plates 24. The cylinder 21 and the mounting frame 23 are both fixedly mounted on the lifting plate 13. The cylinder 21 includes a piston rod and a cylinder body. The piston rod passes through a reserved hole of the mounting frame 23 and extends in a direction away from the cylinder body. The extended end of the piston rod is fixedly connected to a connecting plate 22. Both ends of the connecting plate 22 are respectively sleeved with sliders 25. Two moving grooves 26 are provided on the mounting frame 23. One end of the clamping plate 24 passes through the moving groove 26 and is plugged and connected to the mounting frame 23.

[0025] The slider 25 is also provided with two limiting rods 27, one end of one limiting rod 27 is movably connected to the slider 25, and the other end is movably connected to the mounting frame 23, and the other end of the limiting rod 27 is movably connected to the slider 25, and the other end is movably connected to the clamping plate 24;

[0026] It should be noted that the limiting rod 27 is movably connected to the mounting frame 23, the slider 25 and the clamping plate 24 via a pin;

[0027] When the cylinder 21 is operated, the piston rod moves away from the cylinder body, and the connecting plate 22 fixed on the piston rod moves together with the piston rod toward the clamping plate 24. Due to the restraining effect of the limit rod 27, the clamping plate 24 moves toward the pipe pile, thereby clamping the pipe pile. When the clamping work is completed, the piston rod moves toward the cylinder body, and the clamping plate 24 moves away from the pipe pile, thereby releasing the pipe pile. By controlling the moving distance of the piston rod, the clamping range of the clamping plate 24 can be changed, thereby better adapting to pipe piles of different specifications.

[0028] Since the clamping mechanism 2 is fixedly mounted on the lifting plate 13, and the lifting plate 13 can move up and down along the slide groove 15, during the hammering process, the clamping mechanism 2 clamps the pipe pile and moves downward synchronously. During the downward movement of the lifting plate 13, due to the restraining effect of the connecting block 17 on the slide groove 15, the pipe pile remains vertical during the hammering process to avoid displacement.

[0029] The working principle of the utility model is as follows: the cylinder 21 is started, the piston rod together with the connecting plate 22 moves in the direction away from the cylinder body of the cylinder 21, the slider 25 arranged on the connecting plate 22 and the clamping plate 24 plugged on the mounting frame 23 are constrained by the limit rod 27 and move toward the middle at the same time, thereby clamping the pipe pile; at the same time, the winch 31 reels the steel cable 36, and the hammer 35 is pulled up to the set height, and then the winch 31 releases the steel cable 36, and the hammer 35 falls vertically and hammers the pipe pile, thereby clamping the pipe pile. The holding mechanism 2 clamps the pipe pile and moves downward synchronously, and the pipe pile enters the foundation; after the hammering is completed, the piston rod moves toward the direction close to the cylinder body of the cylinder 21, and due to the constraint of the limit rod 27, the clamping plate 24 moves away from the pipe pile, thereby releasing the pipe pile. At this time, the lifting plate 13 is elastically acted upon by the spring 16, and the lifting plate 13 moves upward synchronously with the clamping mechanism 2, and the clamping mechanism 2 is reset; the clamping mechanism 2 and the hammering mechanism 3 repeat the previous work until the pipe pile is hammered completely into the foundation.

[0030] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
