[0010] A further improvement of the present invention is that the main body includes a support, the top surface of the support is fixedly connected to the bottom surface of the main unit, the front and rear ends of the top surface of the support are fixedly connected to the bottom surface of the movable groove, and the main body is fixedly connected to the bottom surface of the support.

[0012] A further improvement of the present invention is that the clamping mechanism includes a guide rod and a servo motor. The servo motor is fixedly installed on the top surface of the motor bracket. The output shaft of the servo motor is fixedly connected to the lead screw of the lead screw component. The two ends of the lead screw of the lead screw component are connected to the synchronous clamping plates by ball nuts.

[0013] A further improvement of this utility model is that the bottom ends of the two synchronous clamping plates are movably connected to the sliding groove, the other ends of the two synchronous clamping plates are slidably connected to the guide rod, and the guide rod is fixedly connected to the inner walls of both ends of the main body.

[0014] A further improvement of the present invention is that the limiting mechanism includes a limiting fixing groove, the limiting fixing groove is fixedly installed on the inner wall of the synchronous clamping plate, a telescopic rod is provided inside the limiting fixing groove, a spring is sleeved on the outer wall of the telescopic rod, and a limiting block is fixedly connected to the top end of the telescopic rod.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a pile foundation testing and correction device. It comprises a main body structure consisting of a main body, an insertable fixing cone, a sliding groove, a No. 1 level, a support, and a motor support; a clamping mechanism consisting of a guide rod, a servo motor, a lead screw, and a synchronous clamping plate; and a limiting mechanism consisting of a limiting block, a limiting fixing groove, a spring, and a telescopic rod. These three components work together to initially fix the pile foundation. When needed, the levelness of the main body is observed using the No. 1 level, and the insertion depth of the insertable fixing cone is adjusted to keep the device level. Then, the servo motor is started. The output shaft of the servo motor drives the lead screw of the lead screw component to rotate. This causes the lead screw of the lead screw component to drive one end of the two synchronous clamps connected to the thread through the ball nut to move on the lead screw component. At the same time, the other end of the two synchronous clamps slides on the guide rod, and the bottom ends of the two synchronous clamps slide towards each other inside the slide groove. This allows the two limit blocks to smoothly and stably fix the pile foundation. Meanwhile, the spring and telescopic rod can play a buffering role to avoid damage to the pile foundation during the clamping and fixing process.

By setting up a correction mechanism consisting of an adjusting main unit, a movable groove, a first hydraulic rod, a first correction arm, a second correction arm, a second hydraulic rod, a third hydraulic rod, a third correction arm, and an adjusting groove, the device can detect and correct pile foundations. Two detection levels mounted on the top surface of the adjusting main unit can effectively detect the tilt angle of the pile foundation. The adjusting main unit can then be activated, and the first hydraulic rod moves the first correction arm to a suitable angle, followed by the second hydraulic rod moving the second correction arm to a suitable angle. Then, the No. 3 hydraulic rod is activated. The output shaft of the No. 3 hydraulic rod drives the No. 3 straightening arm to move to the appropriate position. Then, a straightening force is applied to the pile foundation through the adjusting groove. At the same time, as the adjusting groove applies a straightening force to the pile foundation, one side of the limiting block in the limiting mechanism applies a pushing force to the pile foundation through the spring and telescopic rod. This causes the pile foundation to be compressed by the spring and telescopic rod on the back of the other side of the limiting block through the other side of the limiting block, providing a reverse force. This keeps the pile foundation stable during the straightening process, thus completing the straightening of the pile foundation. This device has a simple structure, is easy to operate, and can be widely applied to pile foundations of different specifications. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] Example 1

[0026] like Figure 1-5 As shown, this utility model provides a pile foundation testing and correction device, including a main body 1. A clamping mechanism 2 is provided on the inner wall of the main body 1, and a limiting mechanism 3 is provided on the inner wall of the clamping mechanism 2. A correction mechanism 4 is provided on the top surface of the main body 1. The correction mechanism 4 includes an adjusting host 41 and a movable groove 42. A first correction arm 44 is movably connected to both sides of the adjusting host 41. A second correction arm 45 is movably connected to the end of the first correction arm 44 away from the adjusting host 41, and a third correction arm 48 is movably connected to the end of the second correction arm 45 away from the first correction arm 44. An adjustment groove 49 is fixedly connected to the inner wall of the third corrective arm 48. A leveling instrument is installed on the top surface of the adjusting host 41. A first hydraulic rod 43 is movably connected inside the movable groove 42. The output end of the first hydraulic rod 43 is movably connected to the side wall of the first corrective arm 44. A second hydraulic rod 46 is movably connected to the side wall of the first corrective arm 44. The output of the second hydraulic rod 46 is movably connected to the side wall of the second corrective arm 45. A third hydraulic rod 47 is movably connected to the side wall of the second corrective arm 45. The output end of the third hydraulic rod 47 is movably connected to the side of the third corrective arm 48.

[0027] In this embodiment, a correction mechanism 4, consisting of an adjusting host 41, a movable groove 42, a first hydraulic rod 43, a first correction arm 44, a second correction arm 45, a second hydraulic rod 46, a third hydraulic rod 47, a third correction arm 48, and an adjusting groove 49, can be used to detect and correct the pile foundation. Two level instruments mounted on the top surface of the adjusting host 41 can effectively detect the tilt angle of the pile foundation. This allows the adjusting host 41 to be activated. The adjusting host 41 uses the first hydraulic rod 43 to move the first correction arm 44 to a suitable angle, and then uses the second hydraulic rod 46 to move the second correction arm... 45. Move to the appropriate angle, and then activate the third hydraulic rod 47. The output shaft of the third hydraulic rod 47 drives the third straightening arm 48 to move to the appropriate position. Then, a straightening force is applied to the pile foundation through the adjusting groove 49. At the same time, as the adjusting groove 49 applies a straightening force to the pile foundation, one side of the limiting block 31 in the limiting mechanism 3 applies a pushing force to the pile foundation through the spring 33 and the telescopic rod 34. This causes the pile foundation to be compressed by the spring 33 and the telescopic rod 34 on the back of the other side of the limiting block 31 through the other side of the limiting block 31, providing a reverse force. This keeps the pile foundation stable during the straightening process, thus completing the straightening of the pile foundation.

[0028] Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the main body mechanism 1 includes a bracket 15, the top surface of the bracket 15 is fixedly connected to the bottom surface of the adjusting host 41, the front and rear ends of the top surface of the bracket 15 are fixedly connected to the bottom surface of the movable groove 42, the bottom surface of the bracket 15 is fixedly connected to the main body 11, the top surface of the middle part of the main body 11 is provided with a sliding groove 13, a level 14 is provided on the front and rear sides of the main body 11, a motor bracket 16 is fixedly connected to the right side of the main body 11, and insertion fixing cones 12 are provided on the bottom surfaces of the left and right ends of the main body 11. The clamping mechanism 2 includes a guide rod 21 and a servo motor 22, the servo motor 22 is fixedly mounted on... Mounted on the top surface of the motor bracket 16, the output shaft of the servo motor 22 is fixedly connected to the lead screw of the lead screw component 23. The two ends of the lead screw of the lead screw component 23 are threadedly connected to the synchronous clamping plates 24 through ball nuts. The bottom ends of the two synchronous clamping plates 24 are movably connected to the slide groove 13, and the other ends of the two synchronous clamping plates 24 are slidably connected to the guide rod 21. The guide rod 21 is fixedly connected to the inner walls of both ends of the main body 11. The limiting mechanism 3 includes a limiting fixing groove 32, which is fixedly installed on the inner wall of the synchronous clamping plate 24. A telescopic rod 34 is provided inside the limiting fixing groove 32. A spring 33 is sleeved on the outer wall of the telescopic rod 34, and a limiting block 31 is fixedly connected to the top end of the telescopic rod 34.

[0030] In this embodiment, a main body mechanism 1, consisting of a main body 11, an insertion fixing cone 12, a sliding groove 13, a level 14, a bracket 15, and a motor bracket 16, a clamping mechanism 2, consisting of a guide rod 21, a servo motor 22, a lead screw 23, and a synchronous clamping plate 24, and a limiting mechanism 3, consisting of a limiting block 31, a limiting fixing groove 32, a spring 33, and a telescopic rod 34, works together to initially fix the pile foundation machine. When needed, the levelness of the main body 11 is observed using the level 14, and the insertion depth of the insertion fixing cone 12 is adjusted to keep the device level. Then, the machine is started. The servo motor 22 drives the lead screw of the lead screw component 23 to rotate. This causes the lead screw of the lead screw component 23 to move one end of the two synchronous clamping plates 24 connected to the thread through the ball nut on the lead screw of the lead screw component 23. At the same time, the other end of the two synchronous clamping plates 24 slides on the guide rod 21. This causes the bottom ends of the two synchronous clamping plates 24 to slide towards each other inside the slide groove 13. This allows the two limit blocks 31 to smoothly and stably fix the pile foundation. Meanwhile, the spring 33 and the telescopic rod 34 can play a buffering role to prevent damage to the pile foundation during the clamping and fixing process.

[0031] The working principle of this pile foundation testing and correction device will be explained in detail below.

[0032] like Figure 1-5As shown, during use, the levelness of the main body 11 is observed using the No. 1 level instrument 14, and the insertion depth of the insertion fixing cone 12 is adjusted to keep the device level. Then, the servo motor 22 is started, and the output shaft of the servo motor 22 drives the lead screw of the lead screw component 23 to rotate. This causes the lead screw of the lead screw component 23 to drive one end of the two synchronous clamping plates 24 connected to the thread on the lead screw component 23 through the ball nut, while the other end of the two synchronous clamping plates 24 slides on the guide rod 21. This causes the bottom ends of the two synchronous clamping plates 24 to slide towards each other inside the sliding groove 13, so that the two limiting blocks 31 can smoothly and stably fix the pile foundation. At the same time, the spring 33 and the telescopic rod 34 can play a buffering role to avoid damage to the pile foundation during the clamping and fixing process. Then, the leveling instruments set on the top surface of the adjusting host 41 can be used to check the levelness of the pile foundation. To effectively detect the tilt angle of the pile foundation, the adjusting host 41 can be activated. The adjusting host 41 moves the first straightening arm 44 to a suitable angle via the first hydraulic rod 43, and then moves the second straightening arm 45 to a suitable angle via the second hydraulic rod 46. Then, the third hydraulic rod 47 is activated, and the output shaft of the third hydraulic rod 47 drives the third straightening arm 48 to a suitable position. Then, a straightening force is applied to the pile foundation via the adjusting groove 49. At the same time, as the adjusting groove 49 applies a straightening force to the pile foundation, one side of the limiting block 31 in the limiting mechanism 3 applies a pushing force to the pile foundation via the spring 33 and the telescopic rod 34. This causes the pile foundation to be compressed by the spring 33 and the telescopic rod 34 on the back of the other side of the limiting block 31, providing a reverse force. This keeps the pile foundation stable during the straightening process, thus completing the straightening of the pile foundation.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
