[0002] The guide device for the pile integrity testing probe is a key component that ensures the stable operation and accurate detection of the probe during pile testing. It guides the probe smoothly into the sonic logging tube, preventing damage from collisions with the tube wall and ensuring the accuracy of the test data and the efficiency of the testing process.

[0003] However, existing guidance devices for pile foundation integrity testing probes have the following drawbacks:

[0004] (1) The existing pile foundation integrity detection probe guide device has a weak pressure detection function. The current guide device cannot obtain the information of the pipe condition in real time during the detection process. When the pipe is squeezed and deformed, the device may be stuck due to excessive entry.

[0005] (2) The existing pile foundation integrity detection probe guide device has a weak adaptability and guidance function. Many pile foundation integrity detection probe guide devices are difficult to adapt to sonic logging tubes with different diameters and different internal conditions, which may cause poor guidance effect. Utility Model Content

[0006] The purpose of this invention is to provide a guiding device for a pile foundation integrity detection probe to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guide device for a pile foundation integrity detection probe, comprising a pressure feedback component and an adapter component. The pressure feedback component consists of an adjusting plate, a sliding groove, a pressure sensor, a spring, a rotating ring, and a roller.

[0008] The adapter assembly comprises a damping shaft fixedly connected to the center of the back of the adjustment plate, an upper rotating plate, a fixed ring, a fixed cylinder, a connecting cylinder, a connecting ring, and a lower rotating plate. The upper rotating plate is rotatably connected to one end of the outer surface of the damping shaft, the fixed ring is rotatably connected to one end of the upper rotating plate, the fixed cylinder is rotatably connected to the inner wall of the fixed ring, the connecting cylinder is threaded to the lower surface of the fixed cylinder, the connecting ring is rotatably connected to the lower surface of the connecting cylinder, and the lower rotating plate is rotatably connected to the outer surface of the connecting ring.

[0009] Preferably, the inner wall of the spring is provided with a damper, one end of which is fixedly connected to the center of the outer surface of the pressure sensor. The damper can assist the spring deformation in pressing against the pressure sensor.

[0010] Preferably, a rectangular groove is provided at the center of the front of the adjustment plate, and the inner wall of the rectangular groove is provided on the outer surface of the roller. The roller rotates in the rectangular groove on the adjustment plate, and the auxiliary device moves and is guided.

[0011] Preferably, the top of the fixed cylinder is provided with a threaded groove, and the inner wall of the threaded groove is threaded with a sealing cap. When the probe is placed into the fixed cylinder, the sealing cap is placed on the fixed cylinder for installation.

[0014] Compared with this device, the beneficial effects of this utility model are:

[0015] 1. The guide device for the pile foundation integrity detection probe, through the arrangement of an adjusting plate, sliding groove, pressure sensor, spring, rotating ring, and rollers, allows the device to descend along the inner wall of the sonic logging tube when it is placed inside. When the inner wall of the sonic logging tube is deformed by external force, the rollers will move inward under pressure. The rotating rings on both sides of the rollers will move along the sliding groove, compressing the springs and causing them to deform. The springs will then press against the pressure sensor at one end. When the pressure sensor reaches a predetermined peak value, a signal will be sent through the device connected to the pressure sensor to stop the downward guidance. This design prevents the sonic logging tube from being squeezed and deformed, which could jam the guide device and cause equipment damage.

[0016] 2. The guide device for the pile foundation integrity detection probe, through the setting of an adjusting plate, a damping shaft, an upper rotating plate, a fixed ring, a fixed cylinder, a connecting cylinder, a connecting ring, and a lower rotating plate, requires the operator to rotate the fixed cylinder and the connecting cylinder before placing the device. This allows the upper rotating plate inside the fixed ring on the fixed cylinder and the lower rotating plate inside the connecting ring on the connecting cylinder to rotate and deform, enabling the upper and lower rotating plates to expand and contract. After adjusting the position, the rolling structure on the damping shaft is rotated to abut against the inner wall of the sonic logging tube. This setting allows the device to abut against the inner wall of sonic logging tubes of different sizes, improving the stable guiding effect of the device. Attached Figure Description

The inner wall of the rotating ring 105 is rotatably connected to the roller 106. Through the arrangement of the adjusting plate 101, sliding groove 102, pressure sensor 103, spring 104, rotating ring 105, and roller 106, when the device is placed into the sonic logging tube, the roller 106 on the inner wall of the adjusting plate 101 will move along... The sonic logging tube rolls down along its inner wall. When the inner wall of the sonic logging tube is deformed by external force, the roller 106 will be forced to move inward.

The rotating rings 105 will compress the spring 104 and deform it, so that the spring 104 presses on the pressure sensor 103 at one end. When the pressure on the pressure sensor 103 reaches the predetermined peak value, a signal will be sent through the device connected to the pressure sensor 103 to stop the downward guidance. This setting can prevent the sonic logging tube from being squeezed and deformed by internal force, which could jam the guide device and cause equipment damage.

The outer surface of the connecting ring 206 is rotatably connected to the lower rotating plate 207. The damping shaft 201 is connected to the adjusting plate 101. The arrangement of the upper rotating plate 201, upper rotating plate 202, fixing ring 203, fixing cylinder 204, connecting cylinder 205, connecting ring 206, and lower rotating plate 207 is such that, before placing the device, the operator needs to rotate the positions of the fixing cylinder 204 and the connecting cylinder 205 to allow the upper rotating plate 202 inside the fixing ring 203 on the fixing cylinder 204 and the lower rotating plate 207 inside the connecting ring 206 on the connecting cylinder 205 to rotate and deform, allowing the upper rotating plate 202 and the lower rotating plate 207 to expand and contract. After adjusting the position, the rolling structure on the damping shaft 201 is rotated to make it abut against the inner wall of the sonic logging tube. This arrangement allows the device to abut against the inner wall of sonic logging tubes of different sizes, improving the stable guiding effect of the device.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: Before placing the equipment, the staff needs to rotate the positions of the fixed cylinder 204 and the connecting cylinder 205 so that the upper rotating plate 202 in the fixed ring 203 of the fixed cylinder 204 and the lower rotating plate 207 in the connecting ring 206 of the connecting cylinder 205 can rotate and deform, so that the upper rotating plate 202 and the lower rotating plate 207 can expand and contract. After adjusting the position, rotate the rolling structure on the damping shaft 201 so that it abuts against the inner wall of the acoustic tube.

[0032] The second step: When the device is placed into the acoustic tube, the roller 106 on the inner wall of the adjusting plate 101 will roll down along the inner wall of the acoustic tube. When the inner wall of the acoustic tube is deformed by external force, the roller 106 will be forced to move inward. The rotating rings 105 on both sides of the roller 106 will move along the sliding groove 102. The rotating rings 105 will compress the spring 104 and deform it, so that the spring 104 presses on the pressure sensor 103 at one end. When the pressure on the pressure sensor 103 reaches the predetermined peak value, a signal will be sent through the device connected to the pressure sensor 103 to stop the downward guidance.
