Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete thickness detector. Background Art
[0002] A concrete thickness detector is an instrument specifically used to measure the thickness of concrete structures. This detector is usually based on different working principles, such as electromagnetic induction, ultrasound or radar, to accurately measure the thickness of concrete structures. It is mainly used to measure the thickness of concrete structures, especially for floor slabs, walls, tunnel concrete and pavement concrete. This equipment is essential to ensure the stability and safety of building structures.
[0003] After searching, a Chinese patent with announcement number CN220170126U discloses a concrete thickness detector. During the measurement operation, it is difficult to ensure that the device and the concrete surface to be measured remain vertical. When the verticality of the operator holding the device cannot be greatly offset, the bottom plate of the device cannot fit tightly with the concrete surface, thereby affecting the detection accuracy of the device. At the same time, although the ruler of the device solves the problem of reading without squatting, it makes the structure of the device complicated, affecting the reliability of the device and the convenience of transfer. Therefore, the structure is simple, so the reliability is high, and it is easy to carry and use. The size of the contact surface at the bottom of the device can be adjusted according to the actual concrete surface conditions, thereby improving the measurement accuracy.
[0004] There are still some shortcomings in the use of the above-mentioned concrete thickness detector. When detecting the thickness of the floor and wall of the concrete structure, a handheld detector is usually used for detection. Since the distribution of the floors and walls to be detected is different, and the handheld detector is limited by the length of the hand, it is not convenient to detect the concrete thickness of the higher wall floors and the top wall floors. It is also not convenient to adjust the angle of the detector according to the angle of the floor wall to be detected, which can easily lead to inaccurate detection data, thereby reducing the adaptability and adjustability of the detector. When high-altitude detection is required, the operator is required to carry the detector and climb to the height for detection, which can easily cause the risk of slipping and falling, thereby reducing the safety of the detection work.

[0032] As attached Figure 1 As shown, a slide groove 18 is provided at the right end of the thickness detector body 1, and a sliding block 19 is slidably connected inside the slide groove 18. A fixed block 20 is fixedly connected to the right end of the sliding block 19, which is convenient for installing a soft brush 22 and driving the soft brush 22 to move, thereby facilitating dust removal.
[0033] As attached Figure 5 As shown, a clamping groove 21 is provided at the top of the fixing block 20, which is conducive to the clamping of the two clamping blocks 25 and is convenient for limiting and fixing the soft brush 22 after rotation.
[0034] As attached Figure 6 As shown, a soft brush 22 is rotatably connected to the middle part of the fixed block 20, and two mounting grooves 23 are arranged inside the top end of the soft brush 22. A second spring 24 is fixedly connected inside the mounting groove 23, and a clamping block 25 is fixedly connected to the other end of the second spring 24. The outer side of the clamping block 25 is slidably connected to the inner side of the mounting groove 23. An elastic rope 26 is arranged at the bottom rear end of the soft brush 22. The two clamping blocks 25 are pushed by the second spring 24 to engage with the clamping groove 21, thereby facilitating the horizontal or vertical limit fixing of the soft brush 22, and the elastic rope 26 is conducive to cooperating with the hook 27 to fix the horizontally stored soft brush 22 to the rear end of the thickness detector body 1.

[0036] As attached Figure 3 As shown, the middle part of the limit rod 14 is fixedly connected to the limit block 15, the front side of the limit block 15 is fixedly connected to the first spring 16, and the other end of the first spring 16 is fixedly connected to the inner front end of the fixed shell 13. The limit block 15 is beneficial to prevent the limit rod 14 from being pulled out of the inner side of the fixed shell 13 when being pulled, and plays a limiting role on the limit rod 14, while the first spring 16 is beneficial to play a rebound pushing role on the limit rod 14, so as to facilitate pushing the limit rod 14 to the inside of the corresponding hole groove 17.
[0037] Working principle: when it is necessary to detect the concrete thickness of the high floor wall, hold the outer rod 7 and pull the limit rod 14 so that the limit rod 14 is pulled out of the corresponding hole groove 17, and then the extension rod 6 is released from the limit, and then the extension rod 6 is pulled so that the extension rod 6 slides on the inner side of the outer rod 7, which is conducive to driving the thickness detector body 1 to rise, so as to adjust the height. After the adjustment, release the pulled limit rod 14, and under the push of the first spring 16 on the limit block 15, the limit rod 14 is pushed into the corresponding hole groove 17, so as to adjust the extension rod 6. The position is limited and fixed, and then when the detection angle of the detector needs to be adjusted according to the angle of the wall, the screw rod 12 is turned to loosen the screw rod 12 to facilitate the release of the fixation of the slider 10, and then the slider 10 is slid so that the slider 10 slides inside the connection box 9, which is convenient for driving the rack 11 to move. The meshing of the rack 11 and the gear 8 is conducive to driving the gear 8 to rotate, so that the gear 8 drives the extension rod 6 to rotate and deviate, so that the angle between the extension rod 6 and the thickness detector body 1 changes, which is conducive to the inclination of the thickness detector body 1, so as to adapt to different angles. After adjusting the wall and floor of the detection head 2, the screw rod 12 is screwed in the opposite direction so that the screw rod 12 rotates in the inner thread of the slider 10, so as to be close to one side of the connection box 9, so as to fix the slider 10 after sliding, so as to fix the adjusted angle. When it is necessary to clean the detection head 2, the sliding block 19 is slid so that the sliding block 19 drives the fixed block 20 and drives the fixed soft brush 22 to move, so as to brush and clean the dust at the bottom of the detection head 2. After cleaning, the sliding block 19 is slid to the rear end of the slide groove 18, and the top card block 25 is pressed so that the top card The block 25 is squeezed to the second spring 24 on the top and retracted into the inside of the installation groove 23, and the soft brush 22 is released from the card slot 21 in the fixed block 20, and then the soft brush 22 is rotated so that the soft brush 22 is placed horizontally and placed at the rear end of the thickness detector body 1. When the soft brush 22 is horizontal, the card block 25 on the rear side of the top will be pushed by the second spring 24 on the rear side to card the card block 25 on the rear side of the top and the card slot 21, and then the elastic rope 26 is hung on the outside of the hook 27, so as to facilitate the fixation of the horizontal soft brush 22, so as to facilitate the storage after cleaning.
