Description

Technical Field

[0001] This application relates to the field of engineering testing technology, specifically a protective layer thickness testing device for engineering supervision. Background Technology

[0002] The protective layer refers to the concrete in reinforced concrete that protects the reinforcing bars and prevents them from being directly exposed. The thickness of the protective layer is the distance from the outermost edge of the outermost reinforcing bar to the concrete surface. The protective layer thickness detection device used in engineering supervision is a device used to measure the thickness of the protective layer of an engineering structure. It usually uses non-destructive testing methods, such as electromagnetic induction, ultrasonic waves, or radar, to detect the thickness of the protective layer, so as to achieve rapid, accurate, and non-destructive detection of the thickness of the structural protective layer.

[0003] Thickness detectors can help engineers assess the integrity of structures and the effectiveness of protective layers to ensure the safety and compliance of projects. However, when the surface of reinforced concrete is uneven, there will be gaps between the probe and the surface of the reinforced concrete, affecting the measurement accuracy of the protective layer thickness detection device. Chinese patent (publication number: CN212674112U) discloses a protective layer thickness detection device for engineering supervision, which makes the detection probe elastic, so that the probe is always in contact with the concrete surface, which can improve the measurement accuracy of the probe. However, the above-mentioned document has the problem that the probe is relatively inconvenient to move, and because the slider in the above-mentioned document moves on the outer surface of the guide rod, the staff also need to use an elastic band to move the slider, and the staff also need to lift it to move it, which makes it inconvenient for the supervisor to detect the protective layer thickness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a protective layer thickness detection device for engineering supervision, which has advantages such as ease of movement and solves the problem of inconvenience in moving the device.

[0005] To achieve the above objectives, this application provides the following technical solution: a protective layer thickness detection device for engineering supervision, including a support plate, a detector body fixed on one side of the top of the support plate, a shift chamber slidably connected to the inner side of the support plate, a moving component for driving the shift chamber to move within the support plate, a telescopic component in the inner cavity of the shift chamber, and a detection probe body fixed at the lower end of the telescopic component;

[0006] The moving component includes a support rod, a toothed plate, a sliding plate, a support plate fixedly installed on the top of the sliding plate, and a motor fixedly installed on the front end of the support plate. The lower end of the toothed plate is engaged with a gear.

[0007] By adopting the above technical solution, the supervisor does not need to move the detection probe body, which can effectively improve the convenience and efficiency of the supervisor during the inspection.

[0008] Furthermore, the moving plate is T-shaped, the moving chamber is fixed to the lower end of the moving plate, and the top of the inner side of the support plate is provided with a sliding hole for the moving plate to pass through its inner side.

[0009] By adopting the above technical solution, the moving plate can penetrate through the inner cavity of the support plate, which facilitates the connection and fixation of the moving plate with the moving chamber, thereby enabling the moving plate to drive the moving chamber to move.

[0010] Furthermore, both ends of the transfer chamber are provided with two circular holes for sliding on the outer surface of the support rod.

[0011] By adopting the above technical solution, the transfer chamber can slide on the outer surface of the support rod through two circular holes, which further improves the stability of the support rod during the transfer chamber movement.

[0012] Furthermore, a rotating shaft is fixed to the output end of the motor, and the rotating shaft is fixed to the inside of the gear.

[0013] By adopting the above technical solution, it is easy for the motor to drive the gear to rotate in the inner cavity of the support plate, thereby facilitating the meshing of the gear and the gear plate.

[0014] Furthermore, the telescopic assembly includes a pole, two push rods, two pressure blocks, two slides, a pressure plate fixedly installed on the top of the pole, support blocks fixedly installed at the front and rear ends of the pressure blocks, and springs fixedly installed on opposite sides of the two pressure blocks.

[0015] The above technical solution enables the probe body to be flexible, allowing it to remain in contact with the protective layer surface, thereby improving the accuracy of the probe body during measurement.

[0016] Furthermore, the lower ends of the two push rods are hinged to the top of the pressure plate, and the end of the push rod away from the pressure plate is hinged to the lower end of the pressure block.

[0017] By adopting the above technical solution, the pressure plate can push the two pressure blocks to move in opposite directions (or pull the two pressure blocks to move relative to each other) through the two push rods, which makes it easier for the pressure blocks to squeeze the spring.

[0018] Furthermore, the two grooves are respectively opened on the front and rear walls of the transfer chamber, and the support block is slidably connected to the inside of the groove.

[0019] The front and rear walls of the transfer chamber are provided with grooves for the support block to slide within the chamber.

[0020] By adopting the above technical solution, the support block can move within the transfer chamber, thereby enabling the pressure block to move stably within the transfer chamber.

[0021] Furthermore, the lower end of the transfer chamber is provided with a through hole for the upright to slide within its cavity.

[0022] The above technical solution facilitates the movement of the pole into or out of the inner cavity of the transfer chamber, so that the detection probe body can be stretched and retracted, allowing the detection probe body to remain in contact with the surface of the protective layer.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] The protective layer thickness detection device used in this project supervision has a movable component, which eliminates the need for supervisors to move the detection probe during testing. This significantly improves the convenience and efficiency of the supervisors, while also reducing their workload. Furthermore, the telescopic component allows the detection probe to remain in contact with the protective layer surface, effectively improving the accuracy of the measurement.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 The protective layer thickness detection device for engineering supervision in this embodiment includes a support plate 1, a detector body 2 fixed on one side of the top of the support plate 1, a transfer chamber 4 slidably connected to the inner side of the support plate 1, a moving component 3 for driving the transfer chamber 4 to move within the inner side of the support plate 1, a telescopic component 5 in the inner cavity of the transfer chamber 4, and a detection probe body 6 fixed at the lower end of the telescopic component 5.

[0031] Secondly, the detector body 2 is electrically connected to the detection probe body 6 via a wire, so that the detection probe body 6 can transmit the detection structure to the detector body 2.

[0032] Please see Figure 2 In this embodiment, the moving component 3 includes a support rod 31, a toothed plate 35, a moving plate 32, a support plate 33 fixedly installed on the top of the moving plate 32, and a motor 34 fixedly installed on the front end of the support plate 33. The lower end of the toothed plate 35 is engaged with a gear 36.

[0033] The sliding plate 32 is T-shaped, and the sliding chamber 4 is fixed to the lower end of the sliding plate 32. The top of the inner side of the support plate 1 is provided with a sliding hole for the sliding plate 32 to pass through its inner side, so that the sliding chamber 4 can be connected to the support plate 33. This allows the support plate 33 to drive the sliding chamber 4 to slide on the outer surface of the support rod 31, and the support rod 31 can further improve the stability of the sliding chamber 4 when it moves.

[0034] Furthermore, two circular holes are provided at both ends of the transfer chamber 4 for sliding on the outer surface of the support rod 31, and the support rod 31 is fixed to the inner side of the support plate 1, so that the transfer chamber 4 can slide on the outer surface of the support rod 31 and move on the inner side of the support plate 1.

[0035] In addition, a rotating shaft is fixed to the output end of the motor 34. The rotating shaft is fixed to the inside of the gear 36, and a rotating hole is opened at the front end of the support plate 33 so that the rotating shaft passes through to the outside of the rotating hole, so that the motor 34 can drive the gear 36 to rotate through the rotating shaft. The gear plate 35 is fixed to the top of the inner cavity of the support plate 1 so that the gear 36 meshes with the gear plate 35, thereby allowing the gear 36 to move in the inner cavity of the support plate 1 along with the gear plate 35.

[0036] Please see Figure 3 In this embodiment, the telescopic assembly 5 includes a pole 51, two push rods 53, two pressure blocks 54, two sliding grooves 57, a pressure plate 52 fixedly installed on the top of the pole 51, support blocks 55 fixedly installed at the front and rear ends of the pressure blocks 54, and springs 56 fixedly installed on opposite sides of the two pressure blocks 54. The ends of the two springs 56 away from the pressure blocks 54 are respectively fixed to the left and right walls of the inner cavity of the transfer chamber 4, so that the pressure blocks 54 can squeeze the springs 56.

[0037] Meanwhile, the lower ends of the two push rods 53 are hinged to the top of the pressure plate 52, and the end of the push rod 53 away from the pressure plate 52 is hinged to the lower end of the pressure block 54, so that when the pressure plate 52 squeezes the two push rods 53, the two push rods 53 can push the two pressure blocks 54 to move in opposite directions.

[0038] Furthermore, two grooves 57 are respectively opened on the front and rear walls of the inner cavity of the transfer chamber 4, and the support block 55 is slidably connected to the inside of the groove 57, so that the support block 55 can move through the groove 57 in the inner cavity of the transfer chamber 4, thereby enabling the two pressure blocks 54 to move stably in the inner cavity of the transfer chamber 4.

[0039] In addition, the lower end of the transfer chamber 4 is provided with a through hole for the upright rod 51 to slide in its inner cavity, so that the upright rod 51 can be moved into or removed from the inner cavity of the transfer chamber 4 through the through hole, and the upright rod 51 is fixed to the top of the detection probe body 6, thereby enabling the detection probe body 6 to be telescopic.

[0040] It should be noted that the detector body 2, the detector probe body 6, and the electronic components mentioned in the text are all commonly known in the prior art, and the control method is controlled by the control terminal, which is also commonly known in the prior art. Furthermore, the existing power connection technology and power supply are also common knowledge in the field, and those skilled in the art can easily implement them through programming. Therefore, the working principle, circuit connection, and control method will not be described in detail in the text.

[0041] The working principle of the above embodiments is as follows:

[0042] In use, when the supervisor needs to test the thickness of the protective layer, the supervisor controls the motor 34 via the control terminal. The output of the motor 34 drives the gear 36 to rotate through the shaft, allowing the gear 36 to mesh with the toothed plate 35. The gear 36 can then move within the cavity of the support plate 1 via the toothed plate 35, thereby driving the moving plate 32 to move within the cavity of the support plate 1 via the support plate 33. The moving plate 32 then drives the moving chamber 4 to slide on the outer surface of the support rod 31. This eliminates the need for the supervisor to move the detection probe body 6, effectively improving the convenience of the inspection and increasing the detection efficiency. Furthermore, when the detection probe body 6 encounters unevenness during detection, the detection probe body 6 pushes the upright rod 51 to move into the inner cavity of the transfer chamber 4, so that the upright rod 51 can push the pressure plate 52 to move upward, thereby allowing the pressure plate 52 to squeeze the two push rods 53, so that the two push rods 53 can gradually tilt, so that the two push rods 53 can push the two pressure blocks 54 to move in opposite directions in the inner cavity of the transfer chamber 4, so that the two pressure blocks 54 can squeeze the spring 56, thereby enabling the detection probe body 6 to have extensibility, so that the detection probe body 6 can always be in contact with the surface of the protective layer, thereby improving the accuracy of the detection probe body 6 during measurement.
