[0002] Pre-tensioned prestressed concrete pipe piles are widely used in railway systems and have been expanded to industrial and civil construction, municipal administration, metallurgy, ports, highways and other fields. In the Yangtze River Delta and Pearl River Delta regions, due to the geological conditions suitable for the use of pipe piles, the demand for pipe piles has increased sharply, thus quickly forming a new industry. The pipe pile arm is a reinforcement component specially used to improve the performance of pipe piles. It is crucial to ensure the safety of foundation projects.

[0003] The Chinese patent provides a multi-circular arc pipe pile arm, with the publication number CN220746919U, comprising: a box body, wherein the outer surfaces of the box body near the upper and lower ends are fixedly mounted with multiple circular shafts, and the multiple circular shafts are evenly divided into two groups, and further comprising: two left arms, both movably sleeved on the outer surface of one group of the circular shafts; and two right arms, both movably sleeved on the outer surface of the other group of the circular shafts.

[0004] The device can adjust and fix different arc pipe pile sizes to improve work efficiency, but the device can only fix the middle part of the pipe pile. Since the force point is far away from the end, the pipe pile is easily bent under uneven load or external force, and the bearing capacity of the pipe pile is low. Therefore, it is necessary to provide a pipe pile arm. Utility Model Content

[0022] Combination Figure 1-Figure 4 A pipe pile arm comprises a bottom box 1 and a top box 2 which are identically arranged, wherein arm mechanisms 3 are arranged in both the bottom box 1 and the top box 2, and an adjustment mechanism 4 is arranged between the bottom box 1 and the top box 2.

[0023] See also Figure 2 and Figure 3 , it is further obtained that the arm-holding mechanism 3 includes a bidirectional screw rod 303, both ends of which are threadedly connected with ball nuts 305, an arc-shaped clamping plate 307 is fixedly arranged on the ball nut 305, and a multi-layer anti-slip sticker 308 is fixedly arranged in the arc-shaped clamping plate 307; a groove 301 is provided on the bottom box 1, a limiting groove 302 is provided in the groove 301, a limiting block 306 is fixedly arranged at one end of the ball nut 305, the limiting block 306 is slidably connected to the limiting groove 302, the bidirectional screw rod 303 is rotatably arranged in the groove 301, a motor 304 is fixedly arranged at one end of the bottom box 1, and one end of the bidirectional screw rod 303 rotatably passes through the groove 301 and is fixedly connected to the rotating shaft of the motor 304.

[0024] Specifically, by starting the motor 304 to rotate the bidirectional screw rod 303, the ball nut 305 threadedly connected to the two ends of the bidirectional screw rod 303 can drive the arc clamping plate 307 to move towards each other, and the limit block 306 on the ball nut 305 slides in the limit groove 302, which can provide a limit and guide effect on the movement of the ball nut 305, so that the pipe pile arm can fix pipe piles of different sizes. At the same time, the multi-layer anti-slip sticker 308 arranged in the arc clamping plate 307 can improve the stability of the pipe pile when clamping, and avoid the pipe pile from slipping. It has a wide range of applications and high practicality.

[0025] See also Figure 4 , it is further obtained that the adjustment mechanism 4 includes a bottom plate 401 and a top plate 402, and a hinge block 405 and a sliding plate 406 are fixedly arranged in the bottom plate 401 and the top plate 402, and two scissor-type hinge frames 407 are hingedly arranged between the hinge block 405 and the two sets of sliding plates 406, and a reinforcement rod 408 is movably connected between the two scissor-type hinge frames 407, and a hydraulic telescopic rod 409 is hingedly arranged on the bottom reinforcement rod 408, and the telescopic rod of the hydraulic telescopic rod 409 is close to the sliding plate 406. The middle reinforcement rod 408 at one end is hingedly connected; the bottom plate 401 is fixedly set on the bottom box 1, and the top plate 402 is fixedly set on the bottom surface of the top box 2. The bottom plate 401 and the top plate 402 are set in the same way. A sliding groove 403 adapted to the sliding plate 406 is opened in the bottom plate 401, and the sliding plate 406 is slidably connected to the sliding groove 403. A sliding hole is opened on the sliding plate 406, and a sliding rod 404 is fixedly set in the sliding groove 403. The sliding rod 404 and the sliding plate 406 are slidably connected through the sliding hole.

[0026] Specifically, by starting the hydraulic telescopic rod 409, the telescopic rod pulls the reinforcement rod 408 at one end of the scissor-type hinge frame 407, so that the sliding plate 406 can slide along the slide groove 403, and at the same time, the sliding plate 406 slides along the surface of the sliding rod 404. The sliding rod 404 can provide stability and guidance for the sliding plate 406 when it moves. The scissor-type hinge frame 407 begins to close, so that the bottom box 1 and the top box 2 can move toward each other, thereby extending the distance between the bottom box 1 and the top box 2, and then the motor 304 is controlled to clamp and fix the pipe pile. Compared with only clamping and fixing the middle end of the pipe pile, the pipe pile arm of this scheme has the effects of good stability, reduced bending stress and optimized bearing capacity, which greatly improves the stability of the pipe pile.

[0027] In actual operation, the pipe pile is placed in the arc clamping plates 307 at the upper and lower ends, and then the motor 304 is started to rotate the bidirectional screw rod 303, so that the ball nuts 305 threadedly connected to the two ends of the bidirectional screw rod 303 can drive the arc clamping plates 307 to move toward each other, and the limit blocks 306 on the ball nuts 305 slide in the limit grooves 302, which can provide limit and guide effects for the movement of the ball nuts 305, so that the pipe pile arm can fix pipe piles of different sizes, and at the same time, the multi-layer anti-skid stickers 308 arranged in the arc clamping plates 307 can improve the stability of the pipe pile when clamping, and prevent the pipe pile from slipping, which has a wide range of applications and high practicality.

[0028] When fixing the pipe pile, the distance between the bottom box 1 and the top box 2 can be adjusted according to the length of the pipe pile. During adjustment, the hydraulic telescopic rod 409 is started to make the telescopic rod pull the reinforcement rod 408 at one end of the scissor-type hinge frame 407, so that the sliding plate 406 can slide along the slide groove 403, and the sliding plate 406 slides along the surface of the sliding rod 404. The sliding rod 404 can provide stability and guidance for the sliding plate 406 when it moves. The scissor-type hinge frame 407 begins to close, so that the bottom box 1 and the top box 2 can move toward each other, thereby extending the distance between the bottom box 1 and the top box 2, and then the motor 304 is controlled to clamp and fix the pipe pile. Compared with only clamping and fixing the middle end of the pipe pile, the pipe pile arm of this scheme has the effects of good stability, reduced bending stress and optimized bearing capacity, which greatly improves the stability of the pipe pile.
