[0002] In the field of building construction quality inspection, the thickness of the concrete cover for reinforcing steel in concrete structures is one of the important parameters affecting structural durability and safety. Currently, commonly used inspection methods mainly rely on portable rebar scanners or radar detection equipment. Operators must hold the instrument and scan the concrete surface point by point, manually judging whether there are any abnormal areas. However, in practical applications, these traditional inspection methods have many shortcomings.

[0003] First, the complex environment of construction sites, such as high inspection positions, makes it difficult for traditional equipment to flexibly adjust its height and angle, limiting the inspection range and ease of operation. Second, most existing inspection instruments lack automatic marking functions. After discovering anomalies, inspectors usually need to rely on visual inspection or auxiliary tools for manual marking, which is not only inefficient but also prone to positioning errors, affecting the accuracy of subsequent repair or evaluation work. Furthermore, the marking mechanism of some inspection equipment with positioning and marking functions is usually installed on the side of the inspection equipment, making it inconvenient to accurately mark the abnormal parts when anomalies are detected.

[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please refer to Figures 1-8 This utility model provides a concrete protective layer thickness detector with accurate positioning and movement function, including a base plate 1. The bottom of the base plate 1 is equipped with wheels with braking function to facilitate the movement of the equipment. A lifting mechanism is provided on one side of the base plate 1. The lifting mechanism is used to drive the lifting plate 2 to move up and down, thereby adapting to the detection needs of different height positions.

[0033] The lifting mechanism includes a bracket 12 fixedly mounted on the base plate 1. A limiting rod 13 is fixedly mounted on one side of the bracket 12, and a reciprocating screw 14 is rotatably mounted on the other side. One side of the lifting plate 2 is slidably engaged with the limiting rod 13 to provide guidance; the other side is threadedly connected to the reciprocating screw 14, and the lifting action is achieved through screw transmission. The reciprocating screw 14 is coaxially connected to a motor 15, which provides power to drive the lifting plate 2 to rise and fall smoothly.

[0034] A detection mechanism is rotatably mounted on one side of the lifting plate 2. The detection mechanism includes a mounting plate 3, which is located on one side of the lifting plate 2 and has a mounting groove on its surface. A mounting seat 4 is installed in the mounting groove, and a detection instrument 41, such as a non-contact detection device like a rebar scanner or radar detector, is fixedly mounted on the lower side of the mounting seat 4 for measuring the thickness of the concrete cover for reinforcing bars.

[0035] To ensure the stability and reliability of the mounting base 4 during use, fixed seats 31 are provided on both sides of the upper surface of the mounting plate 3. Each fixed seat 31 is equipped with a cylinder 32, and the piston end of the cylinder 32 is connected to a clamp 33. When it is necessary to fix the testing instrument 41, the clamp 33 can clamp and position the mounting base 4 under the drive of the cylinder 32 to ensure stability during the testing process.

[0036] Furthermore, a second motor 21 is fixedly installed on one side of the lifting plate 2. The second motor 21 is coaxially connected to the rotating shaft 22, and one end of the rotating shaft 22 passes through the lifting plate 2 and is fixedly connected to one side of the mounting plate 3. By driving the rotating shaft 22 to rotate through the second motor 21, the mounting plate 3 and the detection mechanism on it can be rotated as a whole, thereby realizing multi-angle detection function and adapting to concrete structures of different heights and inclination angles.

[0037] An anomaly positioning marking mechanism is installed on one side of the testing mechanism. This mechanism can identify and mark areas with abnormal concrete cover thickness during the testing process. The anomaly positioning marking mechanism and the testing mechanism are both housed in a through slot 11 in the base plate 1, which does not occupy external space and facilitates overall movement and operation.

[0038] The abnormal positioning and marking mechanism includes a second cylinder 42, which is fixed to one side of the mounting base 4, and its piston end is connected to a first side plate 44. A rigid shell 49 is rotatably connected to the lower part of the first side plate 44 via a rotating rod. A sponge 491 is installed on one side of the rigid shell 49 for contacting the concrete surface and performing marking operations.

[0039] A guide bar 43 is provided on one side of the mounting base 4, and the side plate 44 slides along the guide bar 43 to ensure the stability and accuracy of its movement direction.

[0040] One end of the rotating rod of the hard shell 49 is connected to a gear 492. A cylinder 441 is mounted on the side plate 44. The piston end of the cylinder 441 is connected to a rack 443, which meshes with the gear 492. By pushing the rack 443 with the cylinder 441, the gear 492 can be rotated, thereby controlling the angle change of the hard shell 49 to make it fit the surface to be measured. Then, by pushing with the cylinder 42, the sponge 491 is brought into contact with the abnormal ground. At this time, the sponge 491 is located directly below the detection instrument 41 and on the same vertical line, which helps to improve the marking accuracy.

[0041] A limiting groove 442 is provided on one side of the side plate 44, and the rack 443 is slidably disposed in the limiting groove 442 to prevent it from deviating during movement and improve structural stability.

[0042] A second side plate 45 is fixedly connected to the lower side of the first side plate 44, and a sliding groove is provided on the second side plate 45. A movable shell 47 is slidably disposed inside the sliding groove, and solid pigment 48 is installed inside the movable shell 47 to provide marking color for the sponge 491. A fourth cylinder 46 is also installed in the sliding groove, and its piston end is connected to the movable shell 47 to drive the movable shell 47 to slide back and forth, thereby controlling the supply of solid pigment 48 to the sponge 491. The device integrates a control system that can control all drive mechanisms of the device.

[0043] In summary, the concrete protective layer thickness detector with accurate positioning and movement function according to this utility model works as follows: the lifting mechanism on the base plate 1 drives the lifting plate 2 to move up and down to adapt to different height detection requirements; the detection mechanism is installed on the rotatable mounting plate 3 to achieve multi-angle detection; when the detection instrument 41 detects an abnormal protective layer thickness, the abnormal positioning mark mechanism is activated, the second cylinder 42 pushes the side plate 44 to move the sponge 491 down, at the same time the third cylinder 441 drives the rack 443 to rotate the gear 492, adjusts the angle of the hard shell 49 so that the sponge 491 fits the surface to be measured, and the fourth cylinder 46 pushes the solid pigment 48 to supply color to the sponge 491.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
