Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and more specifically, to an engineering geological crack measuring device. Background Technology

[0002] In the field of engineering geology, accurately measuring the depth of surface cracks in concrete structures is crucial for assessing structural safety and durability.

[0003] Existing measuring devices typically include a main unit and a handheld testing device. During testing, the operator symmetrically arranges the testing probes of two transducers (a transmitting transducer and a receiving transducer) on both sides of the crack, and applies a coupling agent between the testing probes and the concrete surface to ensure effective transmission of sound waves. The device calculates the depth of the crack by measuring the time (acoustic time) it takes for the ultrasonic wave emitted from the transmitting transducer to travel around the end of the crack to the receiving transducer and then combining this with the known wave velocity.

[0004] To improve detection accuracy, the transducer spacing needs to be adjusted multiple times and repeated measurements are required. However, since the two sets of transducers are relatively independent, the horizontal position of the two sets of transducers needs to be adjusted separately when adjusting the spacing, which is quite troublesome. Moreover, it is not possible to adjust with one hand while holding the host and the detection device in the other, which reduces detection efficiency. Secondly, when applying the coupling agent, the coupling agent needs to be taken first and then applied to the two sets of detection probes one by one, which not only reduces efficiency but also poses a risk of detection interruption due to forgetting to bring consumables. Utility Model Content

[0005] To overcome the aforementioned deficiencies of the prior art, this utility model provides an engineering geological crack measuring device. By setting a connecting rod and a second connecting shaft, the distance between the two sets of transducers can be adjusted simply by pushing the first lever. At the same time, by setting a storage box, which is assembled with the detection equipment, pushing the second lever to push the storage box under the detection probe allows the detection probe to dip into the coupling agent, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an engineering geological crack measuring device, including a detector, a support frame installed on the detector, a transducer slidably installed on the support frame, and a detection probe slidably installed inside the transducer. By coupling the detection end face of the detection probe with the concrete surface, the crack depth can be ultrasonically detected. The support frame is also equipped with a handle for easy holding of the detection device. Pressing down on the handle can make the detection end face of the detection probe tightly coupled with the concrete surface. A connecting rod is provided on the transducer, and a first lever is slidably mounted on the handle. By driving the first lever to slide, the connecting rod can be moved to change the distance between the two sets of transducers. A storage box for storing coupling agent is located at the bottom of the handle. A second lever is also slidably mounted on the handle. By driving the second lever to slide, the storage box can be moved to the bottom of the detection probe, so that the detection probe can dip into the coupling agent.

[0007] In a preferred embodiment, the number of connecting rods is set to two sets. A first connecting shaft is installed at the bottom of the first lever, and a first slider is installed at one end of the first connecting shaft. Both the first connecting shaft and the first slider are slidably installed in the handle. The first lever is connected to the first slider through the first connecting shaft. A second connecting shaft is installed at the bottom of the first slider. The second connecting shaft is slidably installed in the handle, and one end of it extends through to the outside of the handle. One end of the connecting rod is rotatably installed at one end of the second connecting shaft.

[0008] In a preferred embodiment, a mounting base for supporting the transducer is symmetrically slidably mounted on the support frame, a mounting block is mounted on one side of the mounting base, and the other end of the connecting rod is rotatably mounted on the mounting block.

[0009] In a preferred embodiment, a limiting block is slidably installed inside the first slider, and a first spring is also installed inside the first slider, with one end of the first spring connected to the limiting block.

[0010] In a preferred embodiment, the handle has a slot adapted to the limiting block, and multiple sets of slots are provided and are evenly distributed in the handle.

[0011] In a preferred embodiment, a third connecting shaft is installed at the bottom of the second lever, and a second slider is installed on the third connecting shaft. Both the third connecting shaft and the second slider are slidably installed inside the handle, and one end of the third connecting shaft extends through to the outside of the handle.

[0012] In a preferred embodiment, a light rod is symmetrically installed inside the handle, the light rod slides through the interior of the second slider, and a second spring for resetting the second slider is sleeved on the light rod, one end of the second spring being connected to the second slider.

[0013] In a preferred embodiment, a connecting block is installed at one end of the third connecting shaft, a movable block is slidably installed inside the connecting block, a support block is installed at the bottom of the movable block, one side of the support block is connected to the storage box, and a sealing plug is detachably installed on the storage box.

[0014] The technical effects and advantages of this utility model are as follows: By setting a second connecting shaft, connecting rod and mounting block, the two sets of transducers can be moved simultaneously by simply pushing the first lever, allowing them to move apart or toward each other, thereby achieving rapid adjustment of the spacing. Moreover, holding the handle and pushing the first lever can be done with one hand, making the operation simple and quick, and effectively improving the detection efficiency.

[0015] By setting up a second slider, a second spring, a connecting block, a movable block, and a support block, the storage box can be moved below the detection probe for dipping in the coupling agent, and it can also be reset by the action of the second spring to prevent interference with the detection operation. Dipping in the agent instead of manual application makes the operation simple and quick, further improving the detection efficiency. In addition, the coupling agent is assembled on the detection equipment through the storage box, avoiding the risk of forgetting to bring consumables. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figure 1 With appendix Figure 6The invention relates to an engineering geological crack measuring device, comprising a detector 1, a support frame 2 mounted on the detector 1, a transducer 3 slidably mounted on the support frame 2, and a detection probe 5 slidably mounted inside the transducer 3. By coupling the detection end face of the detection probe 5 with the concrete surface, ultrasonic detection of crack depth can be performed. The support frame 2 is also equipped with a handle 4 for easy holding of the detection device. Pressing down on the handle 4 can make the detection end face of the detection probe 5 tightly coupled with the concrete surface.

[0025] The existing geological crack depth detection device described above uses a Bluetooth connection between the detector 1 and an external host (i.e., a terminal device for data reception, display, storage, and analysis). During detection, the two sets of transducers 3 are symmetrically arranged on both sides of the crack, and a coupling agent is applied to the detection probes 5 of the transducers 3. After pressing the detection device to ensure that the detection probes 5 are in close contact with the concrete surface, the detector 1 automatically transmits and receives ultrasonic waves bypassing the end of the crack through the signal cable connected to the transducers 3. The crack depth value can be obtained by calculating the acoustic time difference. To improve accuracy, the spacing between the transducers 3 needs to be adjusted multiple times for repeated measurements (at least three different values). However, since the two sets of transducers 3 are relatively independent, the horizontal position of the two sets of transducers 3 needs to be adjusted separately when adjusting the spacing, which is cumbersome and cannot be adjusted with one hand, reducing detection efficiency. Furthermore, when applying the coupling agent, the coupling agent needs to be taken first and then applied to each of the two sets of detection probes 5, which reduces efficiency and poses a risk of interruption due to forgetting consumables.

[0026] As attached Figure 1 A connecting rod 303 is provided on the transducer 3, and a first lever 401 is slidably installed on the handle 4. By driving the first lever 401 to slide, the connecting rod 303 can be moved to change the distance between the two sets of transducers 3. A storage box 411 for storing coupling agent is provided below the handle 4. A second lever 405 is also slidably installed on the handle 4. By driving the second lever 405 to slide, the storage box 411 can be moved to the bottom of the detection probe 5, so that the detection probe 5 can dip into the coupling agent.

[0027] In this technical solution, by setting a first lever 401 and a connecting rod 303, pushing the first lever 401 to slide can drive the two sets of connecting rods 303 to move. Under the linkage of the connecting rods 303, the two sets of transducers 3 can move apart or towards each other, thereby achieving the purpose of simultaneously adjusting the horizontal position of the two sets of transducers 3. When the operator holds the testing equipment, they only need to use the thumb or forefinger of the same hand to push the first lever 401 to slide, which can complete the distance adjustment of the two sets of transducers 3. The operation is simple and quick, effectively improving the testing efficiency. At the same time, by setting a storage box 411 and a second lever 405, pushing the second lever 405 to slide can move the storage box 411 containing coupling agent to below the detection probe 5. Pressing down on the testing equipment can make the two sets of detection probes 5 move down at the same time and dip into the coupling agent in the storage box 411. The operation is simple and quick, and the storage box 411 is installed on the testing equipment, thus solving the problem of forgetting to bring consumables when working outdoors.

[0028] As attached Figure 1 To be continued Figure 3 To ensure that the two sets of transducers 3 can move apart or towards each other when the first lever 401 is pushed, two sets of connecting rods 303 are provided. A first connecting shaft 402 is installed at the bottom of the first lever 401, and a first slider 403 is installed at one end of the first connecting shaft 402. Both the first connecting shaft 402 and the first slider 403 are slidably installed inside the handle 4. The first lever 401 is connected to the first slider 403 via the first connecting shaft 402. A second connecting shaft 404 is installed at the bottom of the first slider 403, and the second connecting shaft 404 is slidably installed inside the handle 4, with one end extending to the outside of the handle 4. One end of the connecting rod 303 is rotatably mounted on one end of the second connecting shaft 404. Mounting seats 301 for supporting the transducers 3 are symmetrically slidably installed on the support frame 2. A mounting block 302 is installed on one side of the mounting seat 301. The other end of the lever 303 is rotatably mounted on the mounting block 302. When the first lever 401 is pushed to slide, it can drive the first connecting shaft 402 to slide, which in turn drives the first slider 403 to slide. Then, under the connection of the first slider 403, the second connecting shaft 404 is driven to slide synchronously. The second connecting shaft 404 and the mounting block 302 are connected by a connecting rod 303. When the second connecting shaft 404 slides, it can drive one end of the connecting rod 303 to move synchronously. Then, under the linkage of the connecting rod 303, the two sets of mounting blocks 302 are pushed apart or pulled closer. When the mounting blocks 302 move, they can drive the mounting base 301 to move synchronously, which can then make the two sets of transducers 3 move apart or towards each other, thereby achieving the purpose of adjusting the distance between the two sets of transducers 3. This can be achieved simply by pushing the first lever 401. The operation is simple and quick, and the detection efficiency is effectively improved.

[0029] As attached Figure 5 With appendix Figure 6To ensure that the transducer 3 can be fixed after adjusting to the appropriate spacing, a limiting block 413 is slidably installed inside the first slider 403. A first spring 414 is also installed inside the first slider 403, and one end of the first spring 414 is connected to the limiting block 413. A slot 415 adapted to the limiting block 413 is opened inside the handle 4. Multiple sets of slots 415 are provided and are evenly distributed inside the handle 4. When it is necessary to increase the spacing between the two sets of transducers 3, the first lever 401 is pushed in the direction of the detector 1. When it moves, it drives the first slider 403 to move synchronously, and then drives the limiting block 413 to move synchronously. At this time, the limiting block 413 is on its inclined surface and slot. The transducer 403 is squeezed into the first slider 403 by the cooperation of the inner wall of 415 and the first spring 414 is compressed. When the first slider 403 moves to the next slot 415 and the limiting block 413 is aligned with the slot 415, the limiting block 413 rebounds and inserts into the target slot 415 under the action of the first spring 414. Then, under the action of the limiting block 413, the first slider 403 is fixed in the handle 4, which in turn fixes the second connecting shaft 404. Then, under the restriction of the connecting rod 303 and the mounting block 302, the mounting base 301 is fixed, thereby achieving the purpose of fixing the transducer 3 and avoiding the fluctuation of the distance between the two sets of transducers 3 during the detection process, which would affect the detection results.

[0030] It should be noted that the handle 4 has cavities on one side of both the first set of slots 415 and the last set of slots 415 to facilitate the rotation of the first slider 403 (e.g., Figure 6 As shown), after the distance between the two sets of transducers 3 is adjusted to the maximum value, the first lever 401 is pushed to disengage the limiting block 413 from the slot 415, causing the first slider 403 to move into the cavity. Then, the first lever 401 is rotated, and under the connection of the first connecting shaft 402, the first slider 403 is rotated, which in turn drives the limiting block 413 to rotate. After the first lever 401 rotates a certain angle, the inclined surface of the limiting block 413 faces away from the detector 1. Then, the first lever 401 is pushed away from the detector 1. When the inclined surface of the limiting block 413 contacts the inner wall of the handle 4, it will squeeze the limiting block 413 into the first slider 403, so that the first slider 403 can smoothly slide back along the original track. Then, under the linkage of the second connecting shaft 404, the connecting rod 303 and the mounting block 302, the two sets of transducers 3 will be driven to gradually reset. When the first slider 403 moves to the cavity away from the detector 1, the first lever 401 can be rotated again to make the inclined surface of the limiting block 413 face back towards the detector 1, so as to carry out the next detection operation.

[0031] As attached Figure 1 Appendix Figure 4 and attached Figure 6To facilitate the application of coupling agent to the detection end face of the detection probe 5, a third connecting shaft 406 is installed at the bottom of the second lever 405. A second slider 407 is installed on the third connecting shaft 406. Both the third connecting shaft 406 and the second slider 407 are slidably installed inside the handle 4, with one end of the third connecting shaft 406 extending to the outside of the handle 4. A light rod 416 is symmetrically installed inside the handle 4, and the light rod 416 slides through the interior of the second slider 407. A second spring 417 for resetting the second slider 407 is sleeved on the light rod 416. One end of the second spring 417 is connected to the second slider 407. A connecting block 408 is installed at one end of the third connecting shaft 406. A movable block 409 is slidably installed inside the connecting block 408. A support block 410 is installed at the bottom of the movable block 409. One side of the support block 410 is connected to the storage box 411. A sealing plug 412 is detachably installed on the storage box 411. When it is necessary to apply coupling agent, the sealing plug 412 is removed. While holding the handle 4, the second lever 405 is pushed in the direction of the detector 1. During its movement... The third connecting shaft 406 moves synchronously, which in turn moves the second slider 407 synchronously and compresses the second spring 417. When the second slider 407 moves, it can move the connecting block 408 synchronously, which in turn moves the movable block 409. Then, with the support block 410 connected, the storage box 411 is gradually moved below the detection probe 5. When the storage box 411 is below the detection probe 5, the entire device is brought close to the concrete surface or tabletop, so that the bottom of the storage box 411 rests on the concrete surface or tabletop. Then, the handle 4 is pressed down. Since the connecting block 408 and the movable block 409 are slidably connected, the detection probe 5 can move downward relative to the stationary storage box 411 until its detection end face is dipped in the coupling agent. After dipping, the entire device is lifted. At this time, the storage box 411 moves downward away from the detection probe 5 under the action of gravity. Then, the second lever 405 is released. Under the action of the second spring 417, the second slider 407 slides back to its original position, which in turn makes the storage box 411 slide back to its original position, so as to avoid affecting the subsequent detection operation.

[0032] This device, by setting up a second connecting shaft 404, a connecting rod 303, and a mounting block 302, allows the two sets of transducers 3 to move apart or towards each other under the linkage of the connecting rod 303 by pushing the first lever 401 with the thumb or forefinger of the same hand while holding the handle 4. This achieves the purpose of adjusting the distance between the two sets of transducers 3. The operation is simple and quick, effectively improving the detection efficiency. By setting up a limit block 413, a first spring 414, and a slot 415, the insertion of the limit block 413 into the slot 415 allows the transducers 3 to be fixed after moving to the appropriate position, thereby ensuring that the distance between the two sets of transducers 3 is adjusted. To maintain stability and avoid affecting the test results, the device is equipped with a second slider 407, a second spring 417, a connecting block 408, a movable block 409, and a support block 410. Pushing the second lever 405 moves the storage box 411 below the test probe 5. Then, the storage box 411 is placed against a concrete surface or table, and the handle 4 is pressed down to allow the test probe 5 to pick up the coupling agent. The operation is simple and quick, and avoids the risk of forgetting to bring consumables. After the operation is completed, the device is lifted and the second lever 405 is released. Under the action of the second spring 417, the storage box 411 is reset, avoiding affecting subsequent test operations.
