[0002] With the advancement of modernization in the construction industry and the need for transformation and upgrading of traditional construction, there is an urgent need for the development of prefabricated buildings and related technologies. At present, prefabricated concrete structures, one of the main forms of prefabricated buildings, have been widely used and occupy a large market share due to their high degree of industrialization, fast construction speed, superior structural performance, and good economic efficiency.

[0003] Grouting is the process of injecting grout into the fissures, fault fracture zones, or joints and cracks in the foundation of hydraulic structures. Grouting can improve the impermeability and integrity of the grouted strata or structure, improve foundation conditions, and ensure the safe operation of hydraulic structures.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] like Figure 1-5As shown, the present invention proposes a device for detecting the filling degree of cast-in-place pile concrete, comprising a base plate 1 and a detection probe 10. A fixed box 2 is installed on the top of the base plate 1, and a vertical groove 4 is provided above the fixed box 2. A rotating mechanism 3 is provided inside the fixed box 2 and is connected to the vertical groove 4 to drive the vertical groove 4 to rotate. A lifting component 5 is provided inside the vertical groove 4, and a lifting block 6 is provided on the front of the vertical groove 4. The lifting component 5 is connected to the lifting block 6 to drive the lifting block 6 to lift. An installation plate 7 is provided on the front of the lifting block 6, and a displacement mechanism 8 is provided inside the lifting block 6. The displacement mechanism 8 is connected to the installation plate 7 to drive the installation plate 7 to move. An installation mechanism 9 is provided on the front of the installation plate 7 and is connected to the detection probe 10 for installing the detection probe 10.

[0028] In this utility model, the detection probe 10 can be installed through the mounting plate 7 and the mounting mechanism 9. The mounting mechanism 9 allows for quick installation and removal of the detection probe 10, making it convenient to replace the detection probe 10 and preventing damage to the detection probe 10, inconvenient replacement, and thus inaccurate detection results.

[0029] During the testing process, the displacement mechanism 8 can drive the mounting plate 7, mounting mechanism 9, and detection probe 10 to move horizontally, allowing the detection probe 10 to get closer to the cement, thus ensuring stable testing of the cement pile and guaranteeing the test results. Simultaneously, before testing, the lifting assembly 5 can adjust the lifting block 6, displacement mechanism 8, mounting plate 7, mounting mechanism 9, and detection probe 10 to move upwards or downwards, thereby adjusting the height of the detection probe 10 and facilitating testing of the cement pile at different heights. Furthermore, the rotation mechanism 3 can drive the vertical trench 4, lifting assembly 5, lifting block 6, displacement mechanism 8, mounting plate 7, mounting mechanism 9, and detection probe 10 to rotate, allowing the detection probe 10 to change its detection angle horizontally, resulting in a more comprehensive test of the cement pile.

[0030] Through the cooperation of the rotating mechanism 3, the vertical groove 4, the lifting component 5, the lifting block 6, the displacement mechanism 8, the mounting plate 7, and the mounting mechanism 9, the detection probe 10 can detect different heights and angles of the cement-filled pile. At the same time, it also allows the detection probe 10 to be closer to the cement-filled pile during detection, ensuring the detection accuracy of the detection probe 10.

[0031] In the first embodiment, the installation mechanism 9 includes an installation block 91 installed on the front of the installation plate 7. An installation groove 92 is provided on the front of the installation block 91. A connecting block 93 is slidably connected inside the installation groove 92. A detection probe 10 is installed on the front of the connecting block 93. A fixing component 94 is provided inside the installation groove 92. The fixing component 94 is connected to the connecting block 93 and is used to fix the connecting block 93.

[0032] When replacing the detection probe 10, first, the fixing component 94 is used to remove the fixing of the connecting block 93. Then, the connecting block 93 is removed from the mounting slot 92, so that the connecting block 93 and the detection probe 10 can be disassembled, thereby replacing or repairing the detection probe 10.

[0033] The fixing component 94 includes fixing grooves 941 formed on the left and right side walls of the inner cavity of the mounting groove 92. Displacement plates 942 are slidably connected inside the two fixing grooves 941. Positioning blocks 943 are installed on opposite sides of the two displacement plates 942. Positioning grooves 944 are formed on both sides of the connecting block 93. The two positioning blocks 943 are slidably connected inside the two positioning grooves 944. The opposite sides of the two displacement plates 942 are rotatably connected to first threaded rods 945 extending to the outside of the mounting block 91. The two first threaded rods 945 are threadedly connected to the mounting block 91. A knob 946 is installed on the opposite sides of the two first threaded rods 945.

[0034] When the knob 946 is turned, the knob 946 will drive the first threaded rod 945 to rotate. Under the action of the thread thrust, the first threaded rod 945 will perform a translational movement, thereby causing the two first threaded rods 945 to drive the two displacement plates 942 to move to the opposite side or the opposite side respectively. The two displacement plates 942 will drive the two positioning blocks 943 to move to the opposite side or the opposite side respectively. When the two positioning blocks 943 move to the opposite side and are slidably connected inside the two positioning grooves 944 respectively, the connecting block 93 can be fixed, thereby ensuring the stability of the connecting block 93 and the detection probe 10 after installation. When the two positioning blocks 943 move to the opposite side and are disengaged from the two positioning grooves 944 respectively, the fixing of the connecting block 93 is lost, thereby allowing the connecting block 93 and the detection probe 10 to be disassembled.

[0035] In embodiment 2, the displacement mechanism 8 includes a push groove 81 opened on the front of the lifting block 6. An electric push rod 82 is installed inside the push groove 81. The piston rod of the electric push rod 82 is connected to the back of the mounting plate 7. Two guide blocks 83 are installed on both the left and right sides of the lifting block 6. Two guide rods 84 extending to the back of the guide blocks 83 are installed on the back of the mounting plate 7. The two guide rods 84 are slidably connected to the inside of the two guide blocks 83 respectively.

[0036] When the electric push rod 82 is activated, the piston rod of the electric push rod 82 will drive the mounting plate 7 to move forward or backward. The mounting plate 7 will drive the mounting mechanism 9 and the detection probe 10 to move forward or backward, so that the detection probe 10 can be closer to the cement pile, ensuring the accuracy of the detection results of the detection probe 10. The mounting plate 7 can be guided by the two guide blocks 83 and the two guide rods 84 to ensure the stability of its movement, thereby ensuring the stability of the movement of the mounting mechanism 9 and the detection probe 10.

[0037] In embodiment 3, the rotating mechanism 3 includes a first servo motor 31 installed on the top wall of the fixed box 2. A fixed plate 32 is installed on the top of the fixed box 2. A rotating circular groove 33 is opened on the top of the fixed plate 32. A rotating circular block 34 is installed inside the rotating circular groove 33. The output shaft of the first servo motor 31 is connected to the bottom of the rotating circular block 34. The top of the rotating circular block 34 is connected to the bottom of the vertical groove 4. A limit component 35 is provided at the bottom of the rotating circular block 34. Multiple heat dissipation holes extending into the interior are opened on the left and right sides of the fixed box 2.

[0038] When the first servo motor 31 is started, the output shaft of the first servo motor 31 will drive the rotating block 34 to move inside the rotating groove 33. The rotating block 34 will drive the vertical groove 4 to rotate. Under the action of the lifting component 5, lifting block 6, mounting plate 7, displacement mechanism 8 and mounting mechanism 9, the detection probe 10 will rotate, thereby adjusting the detection angle of the detection probe 10 in the horizontal direction.

[0039] The fixed disk 32 and the rotating groove 33 can guide the rotating block 34 to ensure the stability of the rotation of the rotating block 34.

[0040] The limiting component 35 includes a semi-circular limiting groove 351 formed in the bottom wall of the rotating circular groove 33, and a limiting block 352 installed at the bottom of the rotating circular block 34. The limiting block 352 is slidably connected to the inside of the semi-circular limiting groove 351. The semi-circular limiting groove 351 is located in front of the rotating circular groove 33. The semi-circular limiting groove 351 and the limiting block 352 can limit the rotating circular block 34, so that the rotating circular block 34 can only rotate 90 degrees clockwise or counterclockwise.

[0041] In embodiment four, the lifting assembly 5 includes a second servo motor 51 installed on the top of the vertical groove 4. The output shaft of the second servo motor 51 is equipped with a second threaded rod 52 extending into the interior of the vertical groove 4. A threaded block 53 is threadedly connected to the outer side of the second threaded rod 52. The front side of the threaded block 53 is connected to the back side of the lifting block 6.

[0042] When the second servo motor 51 is started, the output shaft of the second servo motor 51 will drive the second threaded rod 52 to rotate. Under the action of the thread thrust, the second threaded rod 52 will drive the threaded block 53 to move up or down. The threaded block 53 will drive the lifting block 6 to move up or down. Under the action of the mounting plate 7, the displacement mechanism 8 and the mounting mechanism 9, the detection probe 10 will move up or down, thereby adjusting the detection height of the detection probe 10.

[0043] In Example 5, a PCL controller is installed on the top of the base plate 1, and a moving mechanism is provided on the bottom of the base plate 1.

[0044] It should be noted that the first servo motor 31, the electric push rod 82, the second servo motor 51, and the detection probe 10 are all electrically connected to the PCL controller. The PCL controller can control the first servo motor 31, the electric push rod 82, and the second servo motor 51. The detection result of adjusting the detection probe 10 will be transmitted to the PCL controller through the wire and displayed on the PCL controller's display screen. Limiting the angle adjustment of the detection probe 10 can prevent the wire from getting tangled.

[0045] The moving mechanism includes a drive box and four rollers. The drive box contains a drive motor, which is connected to the rollers through a transmission structure, such as gear transmission. The moving mechanism enables the detection device to move. The specific structure of the moving mechanism is the same as that of existing rollers and roller drive structures on the market, and will not be described in detail in this article.

[0046] Working principle:

[0047] The device for detecting the concrete filling degree of the cast-in-place pile works by moving the device to a designated position via a moving mechanism. Then, the second servo motor 51 is activated, causing the lifting block 6 to move upwards or downwards. Under the action of the mounting plate 7, displacement mechanism 8, and mounting mechanism 9, the detection probe 10 moves upwards or downwards, thus adjusting the detection height of the probe 10. Next, the first servo motor 31 is activated, causing the rotating block 34 to rotate. The rotating block 34 drives the vertical groove 4 to rotate. Meanwhile, the lifting assembly 5, lifting block 6, mounting plate 7, and displacement mechanism 8... Under the action of the installation mechanism 9, the detection probe 10 is rotated, thereby adjusting the detection angle of the detection probe 10 in the horizontal direction. Finally, the electric push rod 82 is activated, which drives the installation plate 7 to move forward or backward. The installation plate 7 drives the installation mechanism 9 and the detection probe 10 to move forward or backward, so that the detection probe 10 can be close to the cement pile. The cement pile is then detected by the detection probe 10. During the detection process, the height, angle, and forward / backward adjustment of the detection probe 10 can be changed in sequence according to the specific detection situation and position.
