[0054] The supporting body 20511 is slidably connected through the inner wall of the sliding groove 1 20513 and the sliding groove 3 2032, and the inner wall of the connecting groove 1 20512 is provided with a fixing bolt.

[0055] In the above structure, the support body 20511 is slidably connected through the inner wall of the slide groove 1 20513 and the slide groove 3 2032, so that the support component 2051 and the movable component 203 are connected, and the internal thread groove 1 20514 and the screw rod 1 2034 are threadedly connected, so that the driving motor can move the support component 2051 along the direction of the slide groove 3 2032 through the screw rod 1 2034.

[0058] The inner thread groove three 20524 and the screw rod one 2034 are threadedly connected, and the inner thread groove four 20525 and the screw rod two 2035 are slidably sleeved.

[0059] In the above structure, the clamping body 20521 is slidably connected through the inner wall of the slide groove 20523 and the slide groove 3 2032, so that the clamping assembly 2052 and the moving part 203 are connected, and the internal thread groove 3 20524 and the screw rod 1 2034 are threadedly connected, so that the driving motor can move the clamping assembly 2052 along the direction of the slide groove 3 2032 through the screw rod 1 2034. The cross-section of the clamping body 20521 is in a "<" shape, so that when the bottom end of the clamping body 20521 contacts the outer wall of the pile, the top end of the supporting body 20511 will not contact the outer wall of the pile.

[0060] In a preferred embodiment: the engaging assembly 2053 includes a rotating seat 1 20531 and a rotating seat 20532, the end of the rotating seat 1 20531 is rotatably connected to a rotating plate 20534, a side outer wall of the rotating plate 20534 away from the clamping assembly 2052 is fixedly equipped with a plurality of embedded nails 20535, an end of the rotating plate 20534 away from the rotating seat 1 20531 is rotatably connected to the rotating plate 1 20533, the other end of the rotating plate 1 20533 is slidably sleeved with the inner wall of the rotating seat 2 20532, and a side outer wall of the rotating plate 2 20534 close to the clamping assembly 2052 is fixedly equipped with a spring 20536;

[0061] One end of the rotating seat 1 20531 and the rotating seat 2 20532 close to the clamping assembly 2052 are fixedly assembled with the clamping assembly 2052, the spring 20536 is fixedly assembled with the outer wall of the clamping body 20521, and the embedded nail 20535 is arranged obliquely;

[0062] The clamping body 20521 is fixedly assembled with the supporting body 20511 through the second connecting groove 20522 and the fixing bolts arranged on the inner wall of the first connecting groove 20512.

[0063] In the above structure, the second rotating seat 20532, the first rotating seat 20531 and the clamping body 20521 are fixedly assembled, and the first rotating seat 20531, the second rotating plate 20534, the first rotating plate 20533 and the second rotating seat 20532 are rotatably connected. The second rotating plate 20534 is pushed by the second spring 20536, so that the bottom end of the clamping body 20521 in the two sets of relatively arranged clamping jaws 205 is clamped when the pile is clamped. 36 pushes the second rotating plate 20534 to make the end of the first rotating plate 20533 fit with the outer wall of the pile. When the end of the mechanical arm of the excavator 1 drives the clamping jaws 205 to move upward through the connecting component 201, the supporting connecting frame 202, and the moving component 203, if there is movement between the pile and the two groups of clamping jaws 205, the end of the inclined embedded nail 20535 is abutted against the outer wall of the pile through the second spring 20536, thereby increasing the stability between the pile and the two groups of clamping jaws 205;

[0064] refer to Fig.10 , a schematic diagram of the clamping position of the pile located between the two sets of interlocking components 2053;

[0065] In one case, the pile between the two groups of clamping jaws 205 is a round wooden pile. When the two groups of clamping jaws 205 clamp the wooden pile and move upward, if there is movement between the wooden pile and the two groups of clamping jaws 205, the end of the inclined embedded nail 20535 is abutted against the outer wall of the wooden pile through the second spring 20536, so that the embedded nail 20535 and the wooden pile are plugged, and then the stability between the wooden pile and the two groups of clamping jaws 205 is increased through the interlocking assembly 2053. After the installation of the wooden pile is completed, the two groups of clamping jaws 205 move in opposite directions, and the clamping body 20521 drives the second rotating plate 20534 and the first rotating plate 20533 to rotate respectively through the second rotating seat 20532 and the first rotating seat 20531, so that the embedded nail 20535 and the wooden pile are separated;

[0066] Due to the material properties of the wood pile, the embedding of the wood pile by the embedding component 2053 does not affect the use and performance of the wood pile;

[0067] In one case, the pile between the two sets of clamps 205 is a round steel pile. When the two sets of clamps 205 clamp the steel pile and move upward, if there is movement between the steel pile and the two sets of clamps 205, the end of the inclined embedded nail 20535 is abutted against the outer wall of the wooden pile through the spring 20536, so that the embedded nail 20535 and the steel pile are in contact and friction. At the same time, the embedded nail 20535 and the steel pile are in contact and friction, so that the embedded nail 20535 drives the rotating plate 20534 to rotate. The movable seat 1 20531 rotates to increase the contact pressure between the embedded nail 20535 and the steel pile, thereby increasing the stability between the steel pile and the two groups of clamps 205 through the interlocking assembly 2053. After the steel pile is installed, the two groups of clamps 205 move in opposite directions, and the clamping body 20521 drives the rotating plate 2 20534 and the rotating plate 1 20533 to rotate respectively through the rotating seat 2 20532 and the rotating seat 1 20531, thereby separating the embedded nail 20535 from the steel pile.

[0068] Due to the material properties of the steel pile, the interlocking component 2053 squeezes the steel pile, which does not affect the use and performance of the steel pile;

[0069] In one case, the pile between the two groups of clamps 205 is a circular concrete pile. When the two groups of clamps 205 clamp the concrete pile and move upward, if there is movement between the concrete pile and the two groups of clamps 205, the ends of the inclined embedded nails 20535 are abutted against the outer wall of the wooden pile through the spring 20536, so that the embedded nails 20535 and the concrete pile are in contact and friction. At the same time, the embedded nails 20535 and the steel pile are in contact and friction, so that the embedded nails 20535 drive the rotating plate 20534 to rotate. The rotating seat 1 20531 rotates to increase the contact pressure between the embedded nail 20535 and the concrete pile, thereby increasing the stability between the steel pile and the two groups of clamps 205 through the interlocking assembly 2053. After the concrete pile is installed, the two groups of clamps 205 move in opposite directions, and the clamping body 20521 drives the rotating plate 2 20534 and the rotating plate 1 20533 to rotate respectively through the rotating seat 2 20532 and the rotating seat 1 20531, thereby separating the embedded nail 20535 from the concrete pile.

[0070] Due to the material properties of the concrete pile, the engagement component 2053 squeezes the concrete pile, which does not affect the use and performance of the concrete pile;

[0071] The clamping body 20521 is fixedly assembled with the support body 20511 through the connecting groove 20522 and the fixing bolts arranged on the inner wall of the connecting groove 1 20512, so that the clamping body 20521 is supported by the support body 20511, thereby increasing the stability of the clamping assembly 2052 located on the inner wall of the slide groove 3 2032.

[0072] In a preferred embodiment: an inlay groove 20526 is provided on the bottom outer wall of the clamping body 20521 away from the supporting part 2051, a pushing block 20528 is slidably sleeved on the inner wall of the inlay groove 20526, a spring 20527 is fixedly installed on the pushing block 20528 close to the inner wall of the inlay groove 20526, and a pressure sensor 20529 is fixedly installed on the outer wall of the pushing block 20528 away from the spring 20527.

[0073] In the above structure, the controller controls two groups of relatively arranged clamping jaws 205 to move, so that a group of clamping jaws 205 close to the axis of the fixing ring 204 is located in the inner wall of the pile, and a group of clamping jaws 205 far from the axis of the fixing ring 204 is located on the outer wall of the pile. The two groups of clamping jaws 205 move toward each other, so that the clamping jaws 205 squeeze the pile with a certain pressure, and the moving positions of the two groups of clamping jaws 205 are marked. When the clamping jaws 205 squeeze the pile, the detection end of the pressure sensor 20529 fits the outer wall of the pile, and the spring 20527 pushes the pushing block 20528, so that the pressure sensor 20529 realizes pressure detection. After the clamping jaws 205 squeeze the pile, the two groups of clamping jaws 205 move away from each other.

[0074] If the pile is damaged, the concrete on the pile surface will be detached in a large area, that is, the pile is located in the clamping area of ​​the two sets of clamps 205, and the pile is crushed by the clamping of the two sets of clamps 205;

[0075] If the pile is not damaged, the concrete on the pile surface remains unchanged;

[0076] Then the controller controls the two sets of jaws 205 to move toward each other again to the position mark during squeezing. By the change of the pressure detection data of the pressure sensor 20529, it can be determined whether the pile is damaged, thereby solving the problem of pile quality detection.

[0077] In a preferred embodiment: both groups of jaws 205 are slidably connected with the slide groove three 2032 through the slide groove one 20513 and the slide groove two 20523, the first group of support bodies 20511 and the clamping body 20521 are threadedly connected with the screw rod one 2034 through the internal thread groove two 20515 and the internal thread groove four 20525 respectively, and the second group of support bodies 20511 and the clamping body 20521 are threadedly connected with the screw rod two 2035 through the internal thread groove one 20514 and the internal thread groove three 20524 respectively.

[0078] In the above structure, two groups of driving motors are inlaid on the outer wall corresponding to the moving part 203 through the mounting block 206, and the power output shafts of the two groups of driving motors are fixedly assembled with the screw rod 1 2034 and the screw rod 2 2035 respectively, so that the two groups of driving motors can respectively drive the screw rod 1 2034 and the screw rod 2 2035 to rotate. The first group of supporting bodies 20511 and the clamping bodies 20521 are respectively threadedly connected with the screw rod 1 2034 through the internal thread groove 20515 and the internal thread groove 4 20525, and the second group of supporting bodies 20511 and the clamping bodies 20521 are respectively threadedly connected with the screw rod 2 2035 through the internal thread groove 1 20514 and the internal thread groove 3 20524, so that the controller can control the rotation direction of the two groups of driving motors to make the two groups of relatively arranged clamping jaws 205 move, and then make the movement of the moving distance between the plurality of clamping jaws 205, so as to achieve the effect of adapting to different piles.

[0079] Working principle: two groups of driving motors are inlaid on the outer wall corresponding to the moving part 203 through the mounting block 206, and the power output shafts of the two groups of driving motors are fixedly assembled with the screw rod 1 2034 and the screw rod 2 2035 respectively, so that the two groups of driving motors can respectively drive the screw rod 1 2034 and the screw rod 2 2035 to rotate, and the first group of supporting body 20511 and the clamping body 20521 are respectively threadedly connected with the screw rod 1 2034 through the internal thread groove 20515 and the internal thread groove 4 20525, and the second group of supporting body 20511 and the clamping body 20521 are respectively threadedly connected with the screw rod 2 2035 through the internal thread groove 1 20514 and the internal thread groove 3 20524, so that the controller can control the rotation direction of the two groups of driving motors to make the two groups of relatively arranged clamping jaws 205 move, and then make the movement of the moving distance between the plurality of clamping jaws 205, so as to achieve the effect of adapting to different piles;

[0080] The cross section of the clamping body 20521 is in a "<" shape, so that when the bottom end of the clamping body 20521 contacts the outer wall of the pile, the top end of the clamping body 20521 does not contact the outer wall of the pile;

[0081] The controller controls the two groups of relatively arranged clamping jaws 205 to move, so that a group of clamping jaws 205 close to the axis of the fixing ring 204 is located in the inner wall of the pile, and a group of clamping jaws 205 far from the axis of the fixing ring 204 is located on the outer wall of the pile. The two groups of clamping jaws 205 move toward each other, so that the clamping jaws 205 squeeze the pile with a certain pressure, and the moving positions of the two groups of clamping jaws 205 are marked. When the clamping jaws 205 squeeze the pile, the pressure sensor 20529 fits with the outer wall of the pile, and the pressure sensor 20529 pushes the pile through the spring 20527. The push block 20528 is moved to make the pressure sensor 20529 realize pressure detection. After the clamping jaws 205 squeeze the pile, the two groups of clamping jaws 205 move away from each other. If the pile is damaged, the concrete treatment on the pile surface is separated. If the pile is not damaged, the concrete on the pile surface remains unchanged. Then the controller controls the two groups of clamping jaws 205 to move toward each other again to the position mark during squeezing. Through the change of the pressure detection data of the pressure sensor 20529, it can be judged that the pile is damaged, thereby solving the problem of pile quality detection.

[0082] The second rotating seat 20532, the first rotating seat 20531 and the clamping body 20521 are fixedly assembled, and the first rotating seat 20531, the second rotating plate 20534, the first rotating plate 20533 and the second rotating seat 20532 are rotatably connected. The second rotating plate 20534 is pushed by the second spring 20536, so that when the bottom end of the clamping body 20521 in the two sets of relatively arranged clamping jaws 205 clamps the pile, the second spring 20536 pushes the second rotating plate 20534. 0534 makes the end of the embedded nail 20535 fit with the outer wall of the pile. When the end of the mechanical arm of the excavator 1 drives the clamping jaws 205 to move upward through the connecting component 201, the supporting connecting frame 202, and the moving component 203, if there is movement between the pile and the two sets of clamping jaws 205, the end of the inclined embedded nail 20535 is abutted against the outer wall of the pile through the spring 20536, so that the embedded nail 20535 and the pile are plugged, thereby increasing the stability between the pile and the two sets of clamping jaws 205.
