DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] See also Figure 1 In this embodiment, a multifunctional static pressure pile driver comprises a static pressure pile driver body 1. The inner cavity of the clamping head of the static pressure pile driver body 1 is provided with two connecting frames 2. The inner cavities of the two connecting frames 2 are provided with two clamping plates 3. A disassembly mechanism 4 for facilitating replacement of the clamping plates 3 is provided between the inner top wall and the inner bottom wall of the connecting frame 2. Both the front and rear sides of the static pressure pile driver body 1 are provided with protective mechanisms 5 for protection.

[0023] See also Figure 2In order to facilitate the staff to replace the clamping plate 3, the disassembly mechanism 4 in this embodiment includes a rotating rod 401 rotatably connected between the inner top wall and the inner bottom wall of the connecting frame 2 through a bearing, and the top and bottom of the outer surface of the rotating rod 401 are threadedly connected with two screw sleeves 402. The rotating rod 401 is rotated, and the rotation of the rotating rod 401 drives the screw sleeves 402 threadedly connected thereto to move. A moving plate 403 is fixed on the opposite side of the screw sleeves 402 at the left and right ends. At this time, the two screw sleeves 402 at the top and bottom make relative motion, and the movement of the screw sleeves 402 drives the moving plate 403 to move, and the top and A card slot 404 is provided at the bottom, and the opposite sides of the movable plates 403 at the left and right ends penetrate the connecting frame 2 and extend to the inner cavity of the card slot 404. Blocks 405 are fixed on the opposite sides of the upper and lower movable plates 403. The movement of the movable plate 403 drives the block 405 to move from the inner cavity of the card slot 404 to the side close to the horizontal center axis of the card slot 404, which can release the limit on the clamping plate 3, and then move the clamping plate 3 to the side close to the other clamping plate 3, so that the clamping plate 3 can be removed and replaced. Anti-skid pads 406 are fixed on the opposite sides of the two clamping plates 3. The anti-skid pads 406 can increase the friction between the clamping plate 3 and the steel sheet piles.

[0024] Among them, the upper surface of the rotating rod 401 passes through the connecting frame 2 and extends to the upper side of the connecting frame 2 and is fixed with a turning handle. The top and bottom of the outer surface of the rotating rod 401 are fixed with bidirectional threads, and a limiting rod is fixed on the left side of the screw sleeve 402. The inner walls on the opposite sides of the two connecting frames 2 are fixed with limiting strips, and the limiting rod and the limiting strip are slidably connected.

[0025] In this embodiment, guide holes are provided at the top and bottom of the opposite sides of the two connecting frames 2, the size of the inner cavity of the guide hole is adapted to the size of the movable plate 403, the anti-slip pad 406 is a rubber pad, the cross-sectional shape of the card slot 404 is an inverted T shape, and the size of the card block 405 is adapted to the size of the top and bottom of the inner cavity of the card slot 404.

[0026] It should be noted that cylinders for driving the two clamping plates 3 to move relative to each other are provided at both ends of the inner cavity of the clamping head. The setting of the replacement mechanism 4 can facilitate the staff to replace the worn clamping plates 3, thereby improving the stability of the clamping plates 3 clamping the steel sheet piles and reducing the occurrence of deviations.

[0027] See also Figures 3 to 4In order to protect the service life of the static pressure pile driver body 1, the protection mechanism 5 in this embodiment includes protection plates 501 arranged on the front and rear sides of the static pressure pile driver body 1. When the static pressure pile driver body 1 is hit during construction, the protection plate 501 is hit first, and the protection plate 501 moves to the side close to the static pressure pile driver body 1. The left and right ends of the front and rear sides of the static pressure pile driver body 1 are fixed with mounting blocks 502. The left and right ends of the opposite sides of the mounting blocks 502 on the front and rear sides are provided with positioning grooves 503. The positioning grooves 503 are provided on the left and right ends of the opposite sides of the mounting blocks 502 on the front and rear sides. The inner cavity of the static pressure pile driver 3 is slidably connected with a positioning block 504, and the other end of the positioning block 504 is fixed to the protective plate 501. Two spring buffer rods 505 are fixed to the middle of the side opposite to the protective plate 501, so that the spring buffer rods 505 are compressed to absorb the impact force and help the protective plate 501 to return to its original position through elastic restoring force. During the movement of the protective plate 501, the positioning block 504 slides in the positioning groove 503 to adapt to different impact conditions while maintaining the stability of the connection of the protective plate 501.

[0028] The cross-section of the protection plate 501 is arc-shaped, and the positioning groove 503 and the positioning block 504 are inseparable from each other.

[0029] The working principle of the above embodiment is:

[0030] (1) When the clamping plate 3 is worn to the point where it needs to be replaced, first rotate the rotating rod 401. The rotation of the rotating rod 401 drives the screw sleeve 402 threadedly connected to it to move. At this time, due to the setting of the limit rod and the limit bar, the movement of the screw sleeve 402 can be limited so that it can only move in a straight line. At this time, the two screw sleeves 402 at the top and bottom make relative movement. The movement of the screw sleeve 402 drives the moving plate 403 to move. The movement of the moving plate 403 drives the clamping block 405 to move from the inner cavity of the clamping slot 404 to the side close to the horizontal central axis of the clamping slot 404, which can release the limit on the clamping plate 3. Then, the clamping plate 3 is moved to the side close to the other clamping plate 3, and the clamping plate 3 can be removed and replaced.

[0031] (2) When the static pressure pile driver body 1 is hit during construction, the protective plate 501 is hit first, and the protective plate 501 moves to the side close to the static pressure pile driver body 1, so that the spring buffer rod 505 is compressed to absorb the impact force, and the protective plate 501 is helped to return to its original position through the elastic restoring force. During the movement of the protective plate 501, the positioning block 504 slides in the positioning groove 503 to adapt to different impact conditions, while maintaining the stability of the connection of the protective plate 501.
