DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0025] When the present invention is used, the operator first places the base 1 on the rear side of the pile hole, stops the transport vehicle for transporting the precast pile in front of the pile hole, ties the iron chain to one side of the precast pile through the pulley 15, pulls the iron chain to turn the precast pile into a vertical state, and then rotates the first screw 16, which causes the support platforms 17 on both sides to move toward the precast pile synchronously, so that the clamping plates 19 on both sides abut against the precast pile to clamp the precast pile. At the same time, the precast pile is located on the upper side of the circular hole 10, and the operator starts the control component again to cause the clamping plates 19 to move downwards with the precast pile, thereby accelerating the pile sinking speed, using less equipment, and reducing the cost of pile sinking.

[0026] During the pile sinking operation, the prefabricated pile is clamped by the clamping plates 19 on both sides and abuts against the arc plate 12 at the same time, and is limited in multiple directions to ensure the smooth progress of the pile sinking.

[0027] Furthermore, a plurality of rubber strips are installed on opposite sides of the two clamping plates 19 to increase the friction between the clamping plates 19 and the precast piles, while avoiding damage to the precast piles;

[0028] The utility model places the base at the rear side of the pile hole, pulls the precast pile into a vertical state through a pulley, rotates the first screw rod to move the support platforms on both sides, and causes the clamping plates on both sides to clamp the precast pile to perform the pile sinking operation, and the control component controls the clamping plates on both sides, thereby speeding up the pile sinking, improving the pile sinking efficiency and reducing the pile sinking cost.

[0029] The control assembly includes a long plate 20 slidably assembled in the square groove 18, two square rods 21 symmetrically distributed in the front and back are fixedly arranged on the side wall of the long plate 20, a square cavity 22 is provided in the square rod 21, a square plate 23 is slidably assembled in the square cavity 22, a round groove is provided on the side wall of the square rod 21 and is interconnected with the square cavity 22, a round rod 24 matching the round groove is fixedly arranged on the side wall of the square plate 23, the round rod 24 is fixedly connected to the clamping plate 19 at one end away from the long plate 20, a spring 25 matching the round rod 24 is fixedly arranged between the side wall of the square plate 23 and the side wall of the square cavity 22, and two springs symmetrically distributed in the front and back are fixedly arranged on the upper side of the support platform 17. The second electric telescopic rods 26 are linearly distributed, and the output ends of the two second electric telescopic rods 26 are respectively fixedly connected to the two square rods 21. The front and rear side walls of the square groove 18 are both provided with elliptical annular grooves 27. The two round rods 24 are jointly fixed with a limit rod 28 matching the elliptical annular groove 27. The front and rear side walls of the square groove 18 are both provided with vertical grooves 29 interconnected with the elliptical annular groove 27. The upper and lower sides of the two elliptical annular grooves 27 are rotatably equipped with limit plates 30. The two limit plates 30 on the upper and lower sides are centrally symmetrically arranged. The support platform 17 is provided with four limit members matching the limit plates 28.

[0030] When the utility model is not in use, the clamping plate 19 is located inside the square groove 18, so that the length of the round rod 24 extending into the square cavity 22 is the longest, and the spring 25 is at the longest length;

[0031] When the utility model is used, the output end of the second electric telescopic rod 26 first pulls the square rod 21 upwards, and the square rod 21 drives the long board 20, the round rod 24, the clamping plate 19 and the limiting rod 28 to move upwards synchronously, and the limiting rod 28 moves upwards along the elliptical annular groove 27. In the process of moving to the upper side of the elliptical annular groove 27, the limiting rod 28 drives the round rod 24 to extend out of the square cavity 22, so that the clamping plate 19 moves toward the precast pile. In the process of the limiting rod 28 and the elliptical annular groove 27 moving toward the vertical groove 29, the limiting plate 30 is first pushed open, and the limiting rod 28 moves into the vertical groove 29, and then moves to a certain position. After the square rod 21 is in the position, the output end of the second electric telescopic rod 26 is extended, so that the square rod 21 moves downward, and the square rod 21 simultaneously drives the long plate 20, the round rod 24, the clamping plate 19 and the limit rod 28 to move, and the limit plate 30 is reset under the control of the limit member, and the limit rod 28 slides into the elliptical annular groove 27 close to the precast pile along the limit plate 30, and at the same time, the round rod 24 extends out of the square cavity 22, so that the spring 25 is compressed, and the clamping plate 21 abuts against the precast pile at the same time. With the extension of the output end of the second electric telescopic rod 26, the clamping plate 19 drives the precast pile to move downward, accelerating the sinking of the precast pile and improving the pile sinking efficiency;

[0032] When the output end of the second electric telescopic rod 26 drives the square rod 21 to slide downward, when the limit rod 28 pushes the limit plate 30 on the lower side to slide into the vertical groove 29 on the lower side, under the elastic action of the spring 25, the square plate 23 is pushed to move in the square cavity 22 in the direction away from the precast pile, and the square plate 23 pulls the round rod 24 into the square cavity 22, and simultaneously pulls the clamping plate 21 away from the precast column to slide into the square groove 18, and the output end of the second electric telescopic rod 26 is retracted again, so that the clamping plate 19 reciprocates along the elliptical annular groove 27 and the two vertical grooves 29, continuously pushing the precast pile downward, thereby accelerating the pile sinking speed and speeding up the construction progress.

[0033] The limiting member includes a circular groove 31 opened on the side wall of the elliptical annular groove 27, and the side wall of the circular groove 31 is rotatably equipped with a rotating shaft 32, one end of the rotating shaft 32 is fixedly connected to the side wall of the limiting plate 30, and a torsion spring 33 is installed between the rotating shaft 32 and the side wall of the circular groove 31; in the utility model, under the elastic action of the torsion spring 33, the upper limiting plate 30 always rotates clockwise, and the lower limiting plate 30 rotates counterclockwise, so that the limiting rod 28 passes through the limiting plate 30 and moves to the other side of the elliptical annular groove 27, ensuring the smooth operation of the device.

[0034] A cylinder 34 matching the circular hole 10 is rotatably mounted on the upper side of the base 1, and two semicircular plates 35 symmetrically distributed front and back are rotatably mounted on the lower side of the cylinder 34. A plurality of linearly distributed square blocks 36 are fixedly mounted on the lower sides of the two semicircular plates 35, and a second screw 37 is rotatably mounted on the plurality of square blocks 36 together. When the utility model is used for pile sinking, one side of the precast pile is first placed in the cylinder 34, and the precast pile is pulled to a vertical state. The operator then controls the clamping plates 19 on both sides to clamp the precast pile, and then rotates the second screw 37 to open the two semicircular plates 35 to sink the pile, thereby avoiding accidents and ensuring the safe operation of the device.

[0035] A guard plate 40 matching the clamping plate 19 is fixedly provided on opposite sides of the two support platforms 17 to limit the position of the prefabricated piles and ensure the safe operation of the device.

[0036] A hand wheel 41 is coaxially fixedly disposed on the right side of the first screw rod 16 , so that the user can rotate the first screw rod 16 .
