AI Technical Summary
When existing pile hole sediment detection devices encounter a mixture of solid gravel, the measuring ruler is easily broken and cannot effectively penetrate the sediment layer. In addition, it is necessary to rely on the experience of technicians to determine whether it has reached the bottom, resulting in low detection efficiency and accuracy.
The structural design combines the automatic stop component with the auger rod, and utilizes the difference in hardness between the nut and the bottom surface of the pile hole to achieve automatic stop of the auger rod, avoiding manual judgment of whether it has hit the bottom.
The detection device improves the convenience and accuracy of operation, reduces the reliance on human judgment, and ensures that the auger rod reaches the bottom of the pile hole accurately.

DETAILED DESCRIPTION
[0017] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0018] Combined with attachment Figure 1 and attached Figure 2As shown, a pile hole sediment thickness detection device for engineering supervision includes a base 10, a hollow shaft motor 20, an auger rod 30, and a bracket assembly 40. The bracket assembly 40 is disposed below the base 10. The auger rod 30 is connected to the output end of the hollow shaft motor 20. A lithium battery 70 and a storage box 80 for a control circuit board are respectively disposed on the left and right sides of the hollow shaft motor 20. The auger rod 30 is disposed through the base 10. The auger rod 30 includes a screw portion 31 and a drill head 32. A nut 50 is provided on the screw portion 31 of the auger rod 30 for threaded engagement. When detecting pile hole sediment thickness, the hollow shaft motor 20 drives the auger rod 30 to rotate downward, and the auger rod 30 drills through the sediment layer of the pile hole.
[0019] Combined with attachment Figure 1 and attached Figure 2 As shown, the detection device also includes an automatic stop assembly 60, which includes a fixing frame 61 and a lifting and pressing contact 62. The lifting and pressing contact 62 is provided with a supporting plate portion 621 and a slide plate portion 622 at both ends. The slide plate portion 622 is connected to the fixing frame 61 in a vertical sliding direction. The supporting plate portion 621 is placed on the nut member 50 at the auger rod 30, as shown in the attached Figure 4 As shown, the support plate portion 621 of the lifting and pressing contact member 62 is provided with a plurality of limiting pins 623 for limiting the nut member 50 , and the plurality of limiting pins 623 are fixedly arranged around the nut member 50 .
[0020] Combined with attachment Figure 1 and attached Figure 2 As shown, a fixing bracket 61 is fixedly mounted on the base 10. A stop button 63, electrically connected to the control circuit board, is mounted in an inverted position on the fixing bracket 61. The stop button 63 is positioned opposite the slide 622 of the lift contact 62. A mounting seat 612 for mounting the stop button 63 is provided on the crossbeam 611 of the fixing bracket 61. The mounting seat 612 is located between the guide rods 613 on either side of the fixing bracket 61.
[0021] When detecting the thickness of the pile hole sediment, the hollow shaft motor 20 drives the auger rod 30 to rotate and move downward. At this time, the nut member 50 is in a stationary state relative to the auger rod 30, and the height position of the nut member 50 does not change. Since the hardness of the bottom surface of the pile hole is much greater than the sediment layer, when the drill head 32 of the auger rod 30 reaches the bottom surface of the pile hole, the auger rod 30 cannot continue to move downward, and the auger rod 30 is still in a rotating state. The auger rod 30 rotating in place drives the nut member 50 to rotate and move upward, and the height position of the nut member 50 changes. When the nut member 50 moves upward, it will push the lifting and pressure contact 62 to move upward synchronously, as shown in the attached figure. Figure 3 As shown, the lifting and lowering contact 62 presses the stop button 63, and the hollow shaft motor 20 stops running, so that the auger rod can automatically stop when it reaches the bottom of the pile hole.
[0022] Combined with attachment Figure 1 As shown, the base 10 is equipped with lifting rings 11 around its perimeter. Before testing the pile hole sediment thickness, the lifting rings 11 can be lifted by a crane and the entire testing device lowered into the pile hole. The testing device's bracket assembly 40 includes an intermediate connecting seat 41 and several support legs 42. The intermediate connecting seat 41 is fixedly mounted below the base 10. The upper ends of the support legs 42 are rotatably connected to the intermediate connecting seat 41. The lower ends of the support legs 42 are equipped with support feet 43 for contact with the ground. Pins 431 are fixedly mounted at the bottom of the support legs 43.
