Description

Technical Field

[0001] This utility model relates to the field of concrete testing equipment technology, and in particular to an ultrasonic concrete testing instrument for construction project quality supervision. Background Technology

[0002] An ultrasonic concrete testing instrument is used to detect whether a concrete component is dense or has cracks. It includes a planar transducer, a data transmission line, and a main unit of the testing instrument. The planar transducer is used to test the concrete component by emitting ultrasonic signals. The instrument obtains the test signal based on the ultrasonic signals and transmits it back to the main unit of the testing instrument, which has a display screen for display.

[0003] Existing ultrasonic testing instruments for concrete require manual marking of the distance to be measured at the test location, application of coupling agent to the transducer, alignment with the distance measurement mark, and close contact for measurement. However, this method is inconvenient for quickly aligning the transducer with the distance measurement mark and is prone to misalignment due to external factors, affecting the test. Therefore, there is a need for an ultrasonic testing instrument for concrete used in construction quality supervision that can quickly and stably align the transducer with the mark. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete ultrasonic testing instrument for construction project quality supervision, in order to solve the problem mentioned in the background art. Existing concrete ultrasonic testing instruments require manual marking of the distance to be tested, application of coupling agent to the transducer, alignment with the distance marking line, and close contact for measurement. However, this measurement method is inconvenient to quickly align the transducer with the distance marking line, and is prone to displacement of the transducer and marking line due to external factors, affecting the test.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an ultrasonic testing instrument for concrete used in construction project quality supervision, comprising:

[0007] Ultrasonic testing instrument;

[0008] The fixing mechanism includes a fixing plate fixedly connected to the outer wall of the ultrasonic detector. A support frame is symmetrically fixedly connected to the outer wall of the fixing plate. A support hole corresponding to the transducer of the ultrasonic detector is opened through the middle of the support frame. Connecting frames are symmetrically fixedly connected to the outer walls of both ends of the support frame. A support block is fixedly connected to the top outer wall of one side of the connecting frame. A connecting plate is fixedly connected to the top outer wall of the support block. An adjusting plate is fixedly connected to the top outer wall of the connecting frame on the other side. A first limiting hole is opened at equal intervals between the adjusting plate and the connecting plate. A first limiting rod is threadedly connected to the inner wall of the first limiting hole.

[0009] Furthermore, it also includes a sliding mechanism, which includes a fixed frame that contacts the outer wall of the support frame. The outer walls on both sides of the fixed frame are symmetrically provided with sliding grooves, and the inner walls of the sliding grooves are provided with second limiting holes at equal intervals.

[0010] Furthermore, a slide rod that is slidably connected to the inner wall of the slide groove is fixedly connected to the bottom outer wall of the connecting frame, and a second limiting rod is threadedly connected to the second limiting hole of the connecting frame;

[0011] Furthermore, the support frame and the fixing plate are symmetrically threaded together with a third limiting rod, and a protruding groove is connected through the middle of the outer wall of the fixing frame;

[0012] Furthermore, it also includes an air extraction mechanism, which includes suction cups symmetrically fixedly connected to the outer wall of the fixed frame, with a through hole in the middle of the suction cups penetrating the fixed frame;

[0013] Furthermore, the outer wall of the fixed frame is symmetrically fixedly connected with a fixed cylinder communicating with the through hole, the inner wall of the fixed cylinder is slidably connected with a sealing plug, and the outer wall of the sealing plug is fixedly connected with a connecting rod;

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model involves removing the third limiting rod and using a suction cup to attach the fixing frame to the position to be tested. Then, the first limiting rod is removed, and an adjusting plate is slid on the connecting plate. The sliding groove supports the sliding rod, thus supporting the two support frames. The distance between the two support frames is adjusted to a suitable distance. After adjusting, the first limiting rod is installed in the first limiting hole to limit the two support frames. The transducer is inserted into the support hole, and the transducer detection head slides through the extension groove to make the detection head contact the position to be tested. This allows for accurate adjustment of the transducer after supporting the ultrasonic testing instrument, ensuring that the transducer quickly aligns with the marking line and guaranteeing testing accuracy.

[0016] II. Based on the first beneficial effect, manually pulling the connecting rod moves the sealing plug, extracting the air from the space covered by the suction cup, making the suction cup fit tightly against the plane, thereby fixing the fixing frame. Removing the second limiting rod allows the two support frames after limiting to slide along the slide groove. Installing the second limiting rod in the second limiting hole moves the two connecting frames, which can fix the transducer on the plane to be tested and can stably move the transducer to other marking lines.

[0028] Please see Figure 1-4 As shown in the figure, this embodiment is a concrete ultrasonic testing instrument for construction project quality supervision, comprising:

[0029] Ultrasonic testing instrument 1;

[0030] The fixing mechanism includes a fixing plate 201 fixedly connected to the outer wall of the ultrasonic detector 1. A support frame 202 is symmetrically fixedly connected to the outer wall of the fixing plate 201. A support hole 203 corresponding to the transducer of the ultrasonic detector 1 is opened through the middle of the support frame 202. A connecting frame 204 is symmetrically fixedly connected to the outer walls of both ends of the support frame 202. A support block 205 is fixedly connected to the top outer wall of one side of the connecting frame 204. A connecting plate 206 is fixedly connected to the top outer wall of the support block 205. An adjusting plate 207 is fixedly connected to the top outer wall of the other side of the connecting frame 204. A first limiting hole 208 is opened at equal distance between the adjusting plate 207 and the connecting plate 206. A first limiting rod 209 is threadedly connected to the inner wall of the first limiting hole 208.

[0031] The ultrasonic testing instrument 1 is used to test the plane to be tested. The fixed plate 201 supports the support frame 202, the support frame 202 supports the connecting frame 204, the support hole 203 supports the transducer of the ultrasonic testing instrument 1, the connecting frame 204 supports the support block 205, the support block 205 supports the connecting plate 206, and the adjusting plate 207 slides along the connecting plate 206 and then the first limiting rod 209 is installed in the first limiting hole 208 to limit the two support frames 202.

[0032] Working principle: After removing the third limiting rod 307, the fixing frame 301 is adsorbed onto the position to be detected by the suction cup 401. Then, the first limiting rod 209 is removed, and the adjusting plate 207 is slid on the connecting plate 206. The sliding rod 304 is supported by the sliding groove 302, thereby supporting the two support frames 202. The distance between the two support frames 202 is adjusted. After adjusting to a suitable distance, the first limiting rod 209 is installed in the first limiting hole 208 to limit the two support frames 202. The transducer is inserted into the support hole 203, and the transducer detection head passes through the extension groove 306 and slides the transducer to make the detection head contact the position to be detected.

[0033] This step allows the transducer of the ultrasonic testing instrument 1 to be supported and accurately adjusted so that it quickly aligns with the marking line, ensuring the accuracy of the test.

[0034] Please see Figure 1-4 As shown, this embodiment, based on embodiment 1 above, further includes:

[0035] The sliding mechanism includes a fixed frame 301 that contacts the outer wall of the support frame 202. The fixed frame 301 has symmetrically opened sliding grooves 302 on both sides of the outer wall. The inner wall of the sliding groove 302 has equidistant second limiting holes 303.

[0036] The support frame 202 is supported by the fixed frame 301, and the support frame 202 is slidable by the sliding groove 302 and the sliding rod 304;

[0037] A slide rod 304 is fixedly connected to the bottom outer wall of the connecting frame 204 and slidably connected to the inner wall of the slide groove 302. A second limiting rod 305 is threadedly connected to the connecting frame 204 and the second limiting hole 303.

[0038] The support frame 202 is limited by installing a second limiting rod 305 inside the second limiting hole 303;

[0039] The support frame 202 and the fixing plate 201 are symmetrically threaded together with a third limiting rod 307, and the outer wall of the fixing frame 301 is connected through a protruding groove 306;

[0040] When the third limiting rod 307 is installed, the support frame 202 is mounted on the fixed plate 201, and the transducer's detection head can contact the plane through the protruding slot 306.

[0041] The suction mechanism includes suction cups 401 symmetrically fixedly connected to the outer wall of the fixed frame 301, and a through hole 402 is provided in the middle of the suction cups 401 through the fixed frame 301.

[0042] The suction cup 401 is used to attach the mounting bracket 301 to the platform;

[0043] The outer wall of the fixed frame 301 is symmetrically fixedly connected with a fixed cylinder 403 that communicates with the through hole 402. The inner wall of the fixed cylinder 403 is slidably connected with a sealing plug 404. The outer wall of the sealing plug 404 is fixedly connected with a connecting rod 405.

[0044] The connecting rod 405 drives the sealing plug 404 to move inside the fixed cylinder 403, causing the gas to be drawn out through the through hole 402 and covered by the suction cup 401, so that the suction cup 401 is tightly attached to the flat surface.

[0045] Working principle: Manually pull the connecting rod 405 to move the sealing plug 404, extract the air in the space covered by the suction cup 401, so that the suction cup 401 is tightly attached to the plane, thereby fixing the fixing frame 301. Remove the second limiting rod 305 to allow the two support frames 202 after being limited to slide along the slide groove 302. Install the second limiting rod 305 in the second limiting hole 303 to move the two connecting frames 204.

[0046] This step allows the transducer to be fixed on the plane to be tested, or to be moved stably to other marking lines.

[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly.
