Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning equipment technology, specifically a crack detection and positioning device. Background Technology
[0002] Rock and soil crack location devices are equipment used to detect cracks in rock and soil. For example, crack gauges use sensors to convert crack displacement into electrical signals for measurement, and have the characteristics of high precision and dual-system positioning. Non-metallic acoustic detectors use ultrasonic waves for detection. There are also multi-parameter detectors and integrated monitoring machines that can accurately locate and monitor in real time, providing data for engineering safety and other purposes.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology: In most existing crack detection and location equipment, the transducer is manually operated in conjunction with the detector to detect and locate the crack. In actual use, this method requires manual support of the transducer for a long time. Since it is difficult to maintain stability with manual support, it is easy to cause errors in subsequent measurement data, which will affect subsequent construction. Utility Model Content
[0004] The purpose of this invention is to provide a crack detection and location device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a crack detection and positioning device, comprising a fixed base, a fixed block slidably mounted on the upper end of the fixed base, an installation frame rotatably mounted on the upper end of the fixed block, connecting frames fixedly mounted on both the left and right sides of the installation frame, a second rotating gear transducer slidably mounted on the side end of each connecting frame, a second connecting ring fixedly mounted on the lower end of the installation frame, a first connecting ring rotatably mounted on the outer surface of the second connecting ring, and a limit lock snapped onto the side end of the first connecting ring.
[0006] More preferably, a limiting frame is fixedly installed at the upper end of the fixed base, and a first threaded rotating rod is rotatably installed inside the limiting frame, with a first drive motor installed at the upper end of the first threaded rotating rod.
[0007] More preferably, a sliding sleeve is fitted on the outer surface of the first threaded rod, a fixing block is fixedly installed on the side end of the sliding sleeve, and a first connecting ring is fixedly installed on the upper end of the fixing block.
[0008] More preferably, a fixed handle is fixedly installed on the side end of the mounting frame, and two pillars are slidably installed on the side end of the mounting frame away from the fixed handle, with a gasket fixedly installed on the side end of each pillar.
[0009] More preferably, a first rotating gear is rotatably mounted inside the mounting frame, and a second drive motor is mounted on the side end of the first rotating gear.

The first rotating gear and the second rotating gear form a transmission structure. A sliding block is sleeved on the outer surface of each second threaded rod, and a second rotating gear transducer is installed on the side end of each sliding block.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The first drive motor starts and drives the first threaded rod to rotate, which in turn works with the sliding sleeve rod to adjust the height during use. In addition, the first connecting ring, the limit lock and the second connecting ring are rotated to adjust the angle of use. This allows the device to be quickly and easily positioned during use, thereby reducing manual support and improving the accuracy and stability of the device. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1 to 3 This utility model provides a technical solution: a crack detection and positioning device, including a fixed base 1, a fixed block 15 slidably installed on the upper end of the fixed base 1, an installation frame 2 rotatably installed on the upper end of the fixed block 15, connecting frames 3 fixedly installed on both the left and right sides of the installation frame 2, a second rotating gear 33 and a transducer 35 slidably installed on the side end of each connecting frame 3, a second connecting ring 21 fixedly installed on the lower end of the installation frame 2, a first connecting ring 16 rotatably installed on the outer surface of the second connecting ring 21, and a limit lock 17 snapped onto the side end of the first connecting ring 16.
[0017] In this embodiment, as Figure 1 and Figure 2 As shown, a limit frame 11 is fixedly installed at the upper end of the fixed base 1. A first threaded rod 12 is rotatably installed inside the limit frame 11, and a first drive motor 13 is installed at the upper end of the first threaded rod 12.
[0018] In this embodiment, as Figure 1 and Figure 2 As shown, a sliding sleeve 14 is sleeved on the outer surface of the first threaded rotating rod 12, a fixing block 15 is fixedly installed on the side end of the sliding sleeve 14, and a first connecting ring 16 is fixedly installed on the upper end of the fixing block 15.
[0019] In this embodiment, as Figure 1 and Figure 3 As shown, a fixed handle 22 is fixedly installed on the side end of the mounting frame 2, and two pillars 23 are slidably installed on the side end of the mounting frame 2 away from the fixed handle 22. A gasket 24 is fixedly installed on the side end of each pillar 23.
[0020] In this embodiment, as Figure 1 and Figure 3 As shown, a first rotating gear 25 is rotatably mounted inside the mounting frame 2, and a second drive motor 26 is mounted on the side end of the first rotating gear 25.
[0021] In this embodiment, as Figure 1 and Figure 3 As shown, a scale plate 31 is fixedly installed inside each connecting frame 3, and a second threaded rod 32 is rotatably installed inside each connecting frame 3.
[0022] In this embodiment, as Figure 1 and Figure 3As shown, a second rotating gear 33 is fixedly installed on the side end of each second threaded rod 32. Each second rotating gear 33 meshes with the first rotating gear 25. The first rotating gear 25 and the second rotating gear 33 form a transmission structure. A sliding block 34 is sleeved on the outer surface of each second threaded rod 32. A transducer 35 of the second rotating gear 33 is installed on the side end of each sliding block 34.
[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the crack detection and location device operates as follows: First, the user places the device in the designated position, ensuring the mounting frame 2 is firmly against the rock wall along the pad 24. Then, holding the fixing handle 22, the user rotates the mounting frame 2 along the positions of the first connecting ring 16 and the second connecting ring 21, aligning the two connecting frames 3 parallel to the gap. Next, the user presses the limit lock 17 to limit the first connecting ring 16 and the second connecting ring 21. Then, the user starts the first drive motor 13, which drives the first threaded rotating rod 12 to rotate, thereby cooperating with the sliding sleeve rod 14 to push the fixing block 15, mounting frame 2, and other parts to adjust their vertical positions. This aligns the second rotating gear 33 on the side of the connecting frame 3 with the gap. After being placed in close contact, the user activates the second drive motor 26. The second drive motor 26 drives the first rotating gear 25 to rotate, and the meshing second rotating gear 33 drives the two second threaded rotating rods 32 to rotate. This, in conjunction with the connecting frame 3 and the scale plate 31, pushes the two sliding blocks 34 to move closer or further apart. Then, a cable is connected to the side of the transducer 35 of the second rotating gear 33, and the other end of the cable is connected to the controller. Subsequently, according to the scale on the scale plate 31, the transducer 35 of the second rotating gear 33 is moved away to different specified distances, and the electromagnetic waves generated by the detector (HBGJ-150) are used to detect and locate the crack.
