Abstract
Description
Technical Field
[0001] This application relates to the field of auxiliary equipment technology for building construction, and in particular to a borehole detection device for bored piles. Background Technology
[0002] Drilled cast-in-place piles are piles made by forming pile holes in the foundation soil through mechanical drilling, steel pipe soil displacement, or manual excavation on the engineering site, placing a steel cage inside, and pouring concrete. After the construction personnel complete the drilling operation of the bored cast-in-place piles, it is necessary to measure and verify the hole depth.
[0003] Most existing borehole quality inspection devices use a measuring line to drive a sonar probe into the borehole to detect the depth, diameter, position, and shape of the borehole. When not in use, the measuring line is wound around a take-up roller for collection. However, the measuring line tends to bend after being wound for a long time, which affects the accuracy of borehole depth measurement. Therefore, an improvement has been made to a borehole inspection device for bored piles. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a borehole detection device for bored piles, which overcomes the deficiencies of existing technologies and aims to solve the problem that the measuring line is prone to bending after being released after being wound for a long time, and the bent measuring line will affect the accuracy of measuring the hole depth during use.
[0005] To achieve the above objectives, this application provides the following technical solution: a borehole detection device for cast-in-place piles, comprising a detection platform, a mounting base fixedly installed on one side of the upper surface of the detection platform, a take-up roller rotatably installed on the inner side of the mounting base, a measuring line wound on the outer surface of the take-up roller, an anti-winding unit provided on one side of the upper surface of the detection platform located on the take-up roller, a straightening unit provided on one side of the upper surface of the detection platform located on the anti-winding unit, a sonar probe fixedly connected to the end of the measuring line, and a sliding guide rod fixedly installed on the upper surface of the detection platform above the sonar probe.
[0006] By adopting the above technical solution, when the operator needs to measure the depth of the bored pile, the device is placed above the hole, and the take-up roller is rotated to release the measuring line. The measuring line, carrying the sonar probe, gradually descends along the bored pile hole to the bottom. The sonar probe is used to detect the borehole. After being wound for a long time, the measuring line is prone to bending after being released. During the process of lowering the measuring line, the straightening unit can be used to straighten the bent measuring line to prevent the bent measuring line from affecting the accuracy of the measurement data. By setting an anti-winding unit, the measuring line can be wound orderly on the take-up roller.
[0007] As a preferred technical solution of this application, the straightening unit includes a positioning block fixedly installed on the surface of the testing table. A limiting groove is formed inside the positioning block, and a spring is provided inside the limiting groove. The upper end of the spring is fixedly connected to the limiting block, and a stretching roller is rotatably connected to the inner side of the limiting block.
[0008] By adopting the above technical solution, the position of the limiting block is adjusted by the elastic force of the spring, thereby adjusting the vertical height of the stretching roller. When the measuring line passes through the stretching roller, the stretching roller stretches the measuring line, which is prone to bending due to long-term winding, straightening the measuring line and avoiding the bending of the measuring line from affecting the accuracy of the measurement data.
[0009] As a preferred technical solution of this application, guide rollers are fixedly installed on both sides of the straightening unit on the upper surface of the testing table, and an directional cylinder is fixedly installed on the upper surface of the testing table between the guide rollers and the anti-winding unit.
[0010] By adopting the above technical solution, the bending measuring line is stretched and straightened by the cooperation of the guide roller and the straightening unit, and the measuring line and the guide roller are positioned on the same horizontal line by setting the directional cylinder.
[0011] As a preferred technical solution of this application, the anti-winding unit includes a fixed block fixedly installed on the upper surface of the testing table, a reciprocating screw is rotatably connected inside the fixed block, a drive motor for driving the reciprocating screw to rotate is fixedly installed on one side of the fixed block, a moving block is threaded into the outer surface of the reciprocating screw, a guide rod is slidably inserted into the moving block, the two ends of the guide rod are fixedly installed on the inner side of the fixed block, and a guide hole is opened inside the moving block.
[0012] By adopting the above technical solution, the reciprocating screw is driven by the drive motor to rotate, so that the moving block slides back and forth along the guide rod, allowing the measuring line passing through the guide hole inside the moving block to be wound orderly on the take-up roller, thus avoiding the measuring line from getting tangled.
[0013] As a preferred technical solution of this application, a winding motor for driving the winding roller to rotate is fixedly installed on one side of the mounting base.
[0014] By adopting the above technical solution, the measuring line is wound up and unwound by using a winding motor to drive the winding roller.
[0015] As a preferred technical solution of this application, the outer surface of the measuring line is provided with a scale along its length.
[0016] By adopting the above technical solution, after placing the sonar probe at the bottom of the hole, the depth data of the borehole can be obtained by reading the scale on the measuring line.
[0017] The beneficial effects of this application are:
[0018] In this invention, a winding motor drives a winding roller to release the measuring line, allowing the measuring line, carrying a sonar probe, to gradually descend along the borehole of the bored pile to the bottom. The sonar probe is then used to inspect the borehole. Since the measuring line is prone to bending after being wound for a long time, a straightening unit can be used during the lowering process to straighten the bent measuring line, preventing it from affecting the accuracy of the measurement data. An anti-winding unit ensures the measuring line is wound orderly on the winding roller, preventing tangling.
[0019] With reference to the following description and accompanying drawings, specific embodiments of the present invention are disclosed in detail, indicating the ways in which the principles of the present invention can be adopted. It should be understood that the scope of the embodiments of the present invention is not limited thereto. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0026] Reference Figure 1-4A borehole detection device for cast-in-place piles includes a detection platform 1. A mounting base 2 is fixedly installed on one side of the upper surface of the detection platform 1. A winding roller 3 is rotatably installed on the inner side of the mounting base 2. A measuring line 4 is wound around the outer surface of the winding roller 3. An anti-winding unit 6 is provided on one side of the upper surface of the detection platform 1 near the winding roller 3. A straightening unit 7 is provided on one side of the upper surface of the detection platform 1 near the anti-winding unit 6. A sonar probe 9 is fixedly connected to the end of the measuring line 4. A sliding guide rod 8 is fixedly installed on the upper surface of the detection platform 1 above the sonar probe 9. In use, place the device above the borehole, rotate the take-up roller 3 to release the measuring line 4, so that the measuring line 4, carrying the sonar probe 9, gradually descends along the borehole to the bottom of the bored pile. The sonar probe 9 is used to detect the borehole. After being wound for a long time, the measuring line is prone to bending after being released. During the process of lowering the measuring line 4, the straightening unit 7 can be used to straighten the bent measuring line 4 to prevent the bent measuring line 4 from affecting the accuracy of the measurement data. By setting the anti-winding unit 6, the measuring line 4 can be wound orderly on the take-up roller 3.
[0027] In this embodiment, as Figure 1 , 2 As shown in Figure 4, the straightening unit 7 includes a positioning block 71 fixedly installed on the upper surface of the testing table 1. A limiting groove 72 is opened inside the positioning block 71, and a spring 73 is provided inside the limiting groove 72. The upper end of the spring 73 is fixedly connected to a limiting block 74, and a tension roller 75 is rotatably connected to the inner side of the limiting block 74. In use, the position of the limiting block 74 is adjusted by the elastic force of the spring 73, thereby adjusting the vertical height of the tension roller 75. When the measuring line 4 passes through the tension roller 75, the tension roller 75 stretches the measuring line 4, which is prone to bending due to long-term winding, straightening the measuring line 4 and preventing the bent measuring line 4 from affecting the accuracy of the measurement data.
[0028] In this embodiment, as Figure 1 and 2 As shown, guide rollers 10 are fixedly installed on both sides of the straightening unit 7 on the upper surface of the testing table 1. An directional cylinder 11 is fixedly installed on the upper surface of the testing table 1 between the guide rollers 10 and the anti-winding unit 6. In use, the guide rollers 10 and the straightening unit 7 work together to stretch and straighten the bent measuring line 4. The directional cylinder 11 is set to ensure that the measuring line 4 and the guide rollers 10 are on the same horizontal line.
[0029] In this embodiment, as Figure 1 , 2As shown in Figure 3, the anti-winding unit 6 includes a fixed block 61 fixedly installed on the upper surface of the detection table 1. A reciprocating screw 62 is rotatably connected inside the fixed block 61. A drive motor 64 for driving the reciprocating screw 62 to rotate is fixedly installed on one side of the fixed block 61. A moving block 65 is threaded into the outer surface of the reciprocating screw 62. A guide rod 63 is slidably inserted into the inside of the moving block 65. The two ends of the guide rod 63 are fixedly installed on the inner side of the fixed block 61. A guide hole 66 is opened inside the moving block 65. In use, the reciprocating screw 62 is driven to rotate by the drive motor 64, so that the moving block 65 slides back and forth along the guide rod 63, so that the measuring wire 4 passing through the guide hole 66 inside the moving block 65 can be wound orderly on the take-up roller 3, avoiding the measuring wire 4 from winding.
[0030] In this embodiment, as Figure 1 and 2 As shown, a winding motor 5 that drives the winding roller 3 to rotate is fixedly installed on one side of the mounting base 2. The outer surface of the measuring line 4 is provided with a scale 41 along its length. In use, the winding motor 5 drives the winding roller 3 to rotate and wind up the measuring line 4. After the sonar probe 9 is placed at the bottom of the hole, the depth data of the borehole can be obtained by reading the scale 41 on the measuring line 4.
[0031] Working Principle: When using the borehole detection device of this application, when the operator needs to measure the depth of the borehole, the device is placed above the borehole, and the winding motor 5 drives the winding roller 3 to rotate and release the measuring line 4. During the lowering of the measuring line 4, the position of the limiting block 74 is adjusted by the elastic force of the spring 73, thereby adjusting the vertical height of the tension roller 75. When the measuring line 4 passes through the tension roller 75, the tension roller 75 stretches the measuring line 4, which is prone to bending due to long-term winding. The guide roller 10 and the straightening unit 7 work together to straighten the bent measuring line 4. The measuring line 4 is stretched and straightened so that the sonar probe 9 gradually descends to the bottom of the borehole along the bored pile. The sonar probe 9 is used to detect the borehole. After the sonar probe 9 is placed at the bottom of the hole, the depth data of the borehole can be obtained by reading the scale 41 on the measuring line 4. After the measurement is completed, the winding motor 5 is driven to rotate the winding roller 3 to collect the measuring line 4. During the collection process, the reciprocating screw 62 is driven to rotate by the drive motor 64, so that the moving block 65 slides back and forth along the guide rod 63, so that the measuring line 4 passing through the guide hole 66 inside the moving block 65 can be wound orderly on the winding roller 3, avoiding the measuring line 4 from tangling.
