Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic detection, in particular to a pile hole diameter detection device. Background Art

[0002] The detection of pile hole diameter plays a pivotal role in construction. First, from the perspective of construction safety, the size of the hole diameter directly affects the stability and safety during the excavation process. Secondly, from the perspective of construction quality, whether the pile hole diameter meets the design requirements is a key factor in measuring the quality of pile foundation construction. If there is a deviation between the hole diameter and the design requirements, it may lead to insufficient bearing capacity of the pile foundation, thereby affecting the stability and service life of the building. Therefore, it is necessary to test the pile hole diameter;

[0003] Generally, when detecting the inner diameter of a pile hole, the detection device is hoisted into the pile hole by a hoisting device, so as to detect the inner diameter of the pile hole. When the detection device is moved up and down in the pile hole by the steel cable of the hoisting device, the detection device may shake in the pile hole, resulting in inaccurate data. Therefore, a Chinese utility model patent disclosed by the existing publication number CN117107834A discloses a pile hole detection device, which utilizes the synchronous rotation of multiple winches to realize the lifting and lowering action of a mounting seat in the pile hole. The mounting seat is restricted by multiple lifting ropes, has good stability during the lifting process, and can utilize the horizontal detection component to detect the horizontal data of the mounting seat in real time. When the mounting seat is tilted, the controller can control the corresponding driver to operate. Adjust the spacing between the adjusting wheel and the winch in the corresponding lifting assembly to change the relative height between the mounting base and the connection points of each lifting rope, adjust the mounting base to a horizontal posture, and improve the detection accuracy of the distance measuring assembly for the pile hole. In this application, the detection equipment is finally hoisted by four lifting ropes. Although the movement and positioning of the detector can be controlled to a certain extent, it may still shake or shift when moving up and down in the pile hole. If the tension of the cable is inconsistent, the detector may shift. At the same time, if the weight distribution of the detector is uneven, it may cause shifting during movement. In addition, since the detection equipment is hoisted by lifting ropes and has no contact with the inner wall of the pile hole, the detection equipment may also be shaken or shifted due to vibration and other factors.

A positioner 6 is arranged at the lower end of the equipment box 1, and the positioner 6 includes a mounting seat 7 and a plurality of mounting rods 8. The mounting rod 8 is movably installed on one side of the mounting seat 7 through an adjusting rod 9, and a roller 10 is also movably installed on the side of the mounting rod 8 away from the adjusting rod 9.

[0021] like Figure 2-Figure 3 As shown, three mounting holes 11 are provided in the mounting seat 7, and the three mounting holes 11 are provided at different heights. The mounting seat 7 is provided at the lower end of the equipment box 1, and three mounting holes 11 are provided in the mounting seat 7, which can facilitate the installation and adjustment of the three adjustment rods 9. The mounting seat 7 is located below the mounting hole 11 as a fulcrum and is also fixedly installed with a bracket 12. A screw hole A13 is provided at the bottom of the bracket 12. The screw hole A13 is internally threaded to connect a fixing screw A14. The adjusting rod 9 can be limited and fixed by the fixing screw A14. A mounting groove 15 is provided in the mounting rod 8. A screw hole B16 is provided at one side of the bottom of the mounting groove 15. A fixing screw B17 is internally threaded to connect the screw hole B16. Two fixing seats A18 are fixedly installed on the upper end of the mounting rod 8, and one side of the mounting rod 8 is inserted and installed on one side of the adjusting rod 9 and fixed by the fixing screw B17.

[0022] like Figure 3-Figure 4 As shown, a connecting rod 19 is rotatably installed on the outer side of the roller 10 through a pin shaft, and one end of the connecting rod 19 away from the roller 10 is rotatably installed between two fixed seats A18 through a pin shaft. Two fixed seats B20 are also fixedly installed on the side of the connecting rod 19 relative to the mounting rod 8, and a support rod 21 is movably installed between the two fixed seats B20.

[0023] It should be noted that the utility model is a pile hole diameter detection device. When in use, one end of the cable can be hooked on the lifting ring 4, and one end of the signal connection line can be connected to the connection port 5, and the other end of the signal connection line can be electrically connected to the external main control computer. Then, the position of the three rollers 10 can be adjusted according to the diameter of the pile hole, and the adjusting rod 9 can be pushed and pulled in the corresponding mounting hole 11, so that the adjusting rod 9 moves in the corresponding mounting hole 11, so that the adjusting rod 9 drives the roller 10 to adjust the position through the mounting rod 8 and the connecting rod 19, and the scale on the adjusting rod 9 is used to ensure that the adjustment distances of the three adjusting rods 9 are consistent, and then, the fixing screw A14 at the lower end of the corresponding bracket 12 is screwed up in the screw hole A13, and the fixing screw can be used to adjust the pile hole 11. A14 fixes one end of the adjusting rod 9 in the mounting hole 11, and then, the device box 1 can be held by hand to insert the entire device box 1 into the pile hole, and the inner wall of the pile hole will simultaneously press the three rollers 10 toward the mounting rod 8, so that the roller 10 drives the upper end of the connecting rod 19 to rotate between the two fixing seats A18, and at the same time, the two limit blocks 22 rotate at one end of the support rod 21, and make the other end of the support rod 21 move toward the adjusting rod 9 in the mounting groove 15 through the limit blocks 22. At the same time, the limit blocks 22 compress the compression spring 23 toward one end of the adjusting rod 9, and use the force of the compression spring 23, in cooperation with the support rod 21 and the connecting rod 19, so that the roller 10 can be stably on the inner wall of the pile hole and roll along with the downward movement of the device box 1, thereby ensuring the movement stability of the device box 1 in the pile hole;

[0024] Therefore, the piezoelectric ceramic piece inside the ultrasonic transmitter 2 is used to generate sound wave signals, which are propagated to the measured pile foundation aperture with specific frequency and amplitude. Then, the reflected sound wave signals are received by the ultrasonic receiver 3. Next, these data are transmitted to the external main control computer through the connecting line, and these signals are amplified, filtered and detected to extract useful information, such as the sound wave propagation time, amplitude and frequency. Finally, according to the processed data and the known relationship between the speed of sound and the distance, by measuring the propagation time of the sound wave in the concrete, we can calculate the size of the pile foundation aperture and the density of the concrete and other parameters.
