Description

Technical Field

[0001] The present invention belongs to the technical field of thickness detection, and more specifically, relates to a device for detecting sediment thickness at the bottom of a bored cast-in-place pile. Background Art

[0002] Measuring the thickness of sediment at the bottom of bored cast-in-place piles is a key step in ensuring the bearing capacity of the pile foundation and the quality of the project. Sediment is loose sediment such as mud and rock chips left over from the drilling process. If the thickness exceeds the standard, it will significantly reduce the resistance of the pile end, resulting in increased settlement of the pile foundation and even insufficient bearing capacity. Testing can verify the effectiveness of hole cleaning and avoid accidents such as pile sinking and building tilting caused by excessive sediment. The sediment at the bottom of the pile is generally measured using a thickness detection device.

[0003] The thickness detection devices currently in use still have the following problems: 1. When the thickness of the sediment after detection is different, the staff cannot be informed in time, which cannot save the staff's time to observe the scale lines; 2. When there are large errors in the results of multiple sediment thickness detections, it is inconvenient for the staff to quickly adjust the thickness detection position; 3. When the device is carried and circulated, the control buttons may be pressed by mistake, causing the rope to easily become entangled. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the output shaft of the servo motor rotates forward, the three solid conical blocks of the present invention slowly move downward. When the three solid conical blocks contact the bottom of the pile, the three solid conical blocks will stop moving downward. When the output shaft of the servo motor rotates reversely, the three solid conical blocks slowly move upward, making it convenient for workers to measure the thickness of the sediment at the bottom of the pile based on the marks and scale lines on the outer walls of the three solid conical blocks. The provision of three conical receiving holes makes it convenient for workers to store the three solid conical blocks after use.

[0017] In addition, the staff can adjust the angle of the winding bracket by rotating the mounting plate, which is convenient for secondary thickness measurement of pile bottom sediment at different positions. The setting of two movable stabilizing shafts plays a role in limiting the rotating mounting plate, making the rotating mounting plate and the winding bracket more stable after rotation.

[0018] Among them, when the staff rotates the rotating mounting plate, the two support springs E can be automatically compressed, so that the two movable stabilizing shafts are automatically separated from the corresponding two anti-displacement slots; when the rotating mounting plate is rotated to a suitable angle, the two movable stabilizing shafts are automatically reset under the elastic force of the two support springs E.

[0019] 2. In the present invention, when the three solid conical blocks contact the pile bottom and the servo motor drives the winding roller to continue to rotate forward, the three steel ropes may become loose. At this time, the three push frames can automatically move forward under the action of the three support springs F. When the three push frames automatically move forward under the action of the three support springs F, the mounting frame can automatically press the three control switches F.

[0020] In addition, when the thickness detection part is in working state, the installation frame can automatically press the control switch E; when the thickness detection part is in the storage state, the middle wire rope can push the arc detection plate to move backward after being wound. At this time, the installation frame cannot press the control switch E; when the thickness detection part is in working state and the solid conical block is in contact with the bottom of the pile, the controller can control the corresponding LED light to light up; when the three LED lights are on almost at the same time, it means that the sediment thickness detected by the three solid conical blocks is basically the same, and the measurement value at this time has a higher accuracy; when the three LED lights are on at the same time after a period of time, it means that the sediment thickness detected by the three solid conical blocks is different, and there is a large error in the measurement value at this time. The staff does not need to observe the scale line and can readjust the position for secondary measurement; when the thickness detection part is in the storage state, the control switch E and the three control switches F cannot be pressed at the same time to ensure that the three LED lights will not light up when the device is carried or circulated.

[0021] 3. When the three solid conical blocks of the present invention need to be stored after use, the staff needs to push the protective shield to the left to ensure that the protective shield is always outside the controller when the device is carried or circulated, thereby avoiding misoperation of the controller; when the three solid conical blocks are removed for use, the protective shield automatically moves to the right under the action of the two rectangular connecting rods and the two supporting springs G, so that the protective shield is automatically separated from the controller, making it convenient for the staff to control the operation of the servo motor through the controller.

[0051] In the embodiment of the present disclosure, Figure 9 and Figure 10 As shown, the protective shielding portion 600 includes: a circular mounting shaft 601 and a rectangular connecting rod 602; there are two circular mounting shafts 601, and the two circular mounting shafts 601 are fixedly mounted on the rotating mounting plate 101; there are two rectangular connecting rods 602, and the two rectangular connecting rods 602 are slidably mounted on the outside of the two circular mounting shafts 601; the protective shielding portion 600 also includes: a protective shielding cover 603 and a support spring G604; the protective shielding cover 603 is fixedly mounted on the top of the two rectangular connecting rods 602, and the internal space of the protective shielding cover 603 is larger than the controller 300; there are two support springs G604, and the two support springs G604 are sleeved on the outside of the two circular mounting shafts 601, and the two support springs G604 are located on the left side of the two rectangular connecting rods 602;

[0054] When the present invention is used, the staff first places the circular support base 102 on the top of the bored pile, ensuring that the four pins at the bottom of the circular support base 102 are all inserted into the soil, and then separates the three solid conical blocks 405 from the three conical receiving holes 1011. After that, the three solid conical blocks 405 are placed in the bored pile. At this time, the protective shield 603 automatically moves to the right under the action of the two rectangular connecting rods 602 and the two supporting springs G604, so that the protective shield 603 and the controller 300 are in contact. Automatic separation makes it convenient for the staff to control the servo motor 403 through the controller 300; when the output shaft of the servo motor 403 rotates forward, the three solid conical blocks 405 slowly move downward, and when the three solid conical blocks 405 contact the bottom of the pile, the three solid conical blocks 405 will stop moving downward; when the output shaft of the servo motor 403 rotates reversely, the three solid conical blocks 405 slowly move upward, making it convenient for the staff to measure the sediment thickness at the bottom of the pile according to the marks and scale lines on the outer walls of the three solid conical blocks 405;

[0055] When the three solid conical blocks 405 come into contact with the bottom of the pile, the servo motor 403 drives the winding roller 402 to continue to rotate forward, and the three steel ropes 404 may become loose. At this time, the three pushing frames 503 can automatically move forward under the action of the three supporting springs F506; when the three pushing frames 503 automatically move forward under the action of the three supporting springs F506, the mounting frame 501 can automatically press the three control switches F509; when the thickness detection part 400 is in working state, the mounting frame 501 can automatically press the control switch E508; when the thickness detection part 400 is in working state and the solid conical block 405 comes into contact with the bottom of the pile, the controller 300 can control the corresponding LED light 507 to light up; when the three LED lights 5 When LEDs 07 light up at almost the same time, it means that the sediment thickness detected by the three solid conical blocks 405 is basically the same, and the measurement value at this time has a high accuracy; when the three LED lights 507 light up at the same time after a period of time, it means that the sediment thickness detected by the three solid conical blocks 405 is different, and the measurement value at this time has a large error. The staff does not need to observe the scale line and can readjust the position for a second measurement; when the staff rotates the rotating mounting plate 101, the two supporting springs E105 can be automatically compressed, so that the two movable stabilizing shafts 103 are automatically separated from the corresponding two anti-movement slots 1021; when the rotating mounting plate 101 is rotated to a suitable angle, the two movable stabilizing shafts 103 are automatically reset under the elastic force of the two supporting springs E105;

[0056] After the thickness measurement is completed, the staff pushes the protective shield 603 to the left, and then places the three used solid conical blocks 405 in the three conical storage holes 1011 to ensure that the protective shield 603 is always outside the controller 300 when the device is carried or circulated, thereby avoiding the misoperation of the controller 300; when the thickness detection part 400 is in the storage state, the middle steel wire rope 404 can push the arc detection plate 504 to move backward after being wound up. At this time, the mounting frame 501 cannot press the control switch E508; when the thickness detection part 400 is in the storage state, the control switch E508 and the three control switches F509 cannot be pressed at the same time, ensuring that the three LED lights 507 will not light up when the device is carried or circulated.
