[0003] Since in coal mine transportation, the transport vehicle with greater weight can cause a certain degree of damage to the concrete pavement, the concrete pavement needs to be detected regularly to ensure the integrity of the concrete pavement and ensure the smoothness of the conveying line;

[0004] The existing defect detection of coal mine concrete pavement mostly adopts manual visual detection, can only detect the surface of the concrete pavement, and cannot achieve deep detection of the crack of the concrete pavement, the depth of the crack and the damage inside the concrete pavement, resulting in great hidden danger of the concrete pavement. Therefore, it is urgent to design a cement concrete pavement detection device for coal mine to solve the above problems. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a cement concrete pavement detection device for coal mine to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A cement concrete pavement detection device for coal mine, comprising a vehicle frame assembly, the vehicle frame assembly is used at least for cooperating with a traction device to move on the concrete pavement;

[0008] The lower side of the front side of the vehicle frame assembly is provided with an adjusting mechanism, the lower side of the adjusting mechanism is provided with a shooting assembly, and the adjusting mechanism is used at least for adjusting the height of the shooting assembly;

[0009] The top of the vehicle frame assembly is provided with ultrasonic detection host computers on both sides;

[0010] The rear side of the vehicle frame assembly is provided with a stabilizing mechanism, the lower side of the stabilizing mechanism is provided with an ultrasonic assembly, and the ultrasonic assembly is used at least for realizing defect detection of the concrete pavement by ultrasonic waves and returning the detected data to the ultrasonic detection host computer.

[0011] In this way, the device integrates multiple detection means in one, mainly for efficient and accurate detection of cement concrete pavement in coal mines. By adjusting the height of the shooting assembly through the adjusting mechanism, image information of the pavement at different angles can be obtained; the ultrasonic assembly uses ultrasonic technology to detect the depth of the pavement, identifies potential defects or damage, and returns the detection data to the ultrasonic detection host in real time for analysis. At the same time, the design of the frame assembly, the moving assembly and the stabilizing mechanism ensures that the detection device can move and operate stably and flexibly in the complex and changeable coal mine environment.

[0012] Traditional equipment can only perform single type detection, such as relying only on the camera for visual detection or using only ultrasonic for internal defect detection. However, the device combines these two detection means organically, can obtain image information and internal defect data of the pavement at the same time, and provides more comprehensive detection results.

[0013] The design of the adjusting mechanism allows the height of the shooting assembly to be adjusted flexibly, so that the best angle of image information can be obtained for different road conditions and detection requirements.

This adjustment mode is simple and effective and can ensure that the shooting assembly maintains a stable shooting angle in the complex and changeable coal mine environment. After adjusting to the required height, the operator can rotate the locking nut to tightly fit it with the threaded seat, so as to lock the position of the lead screw. This locking function can effectively prevent the lead screw from loosening due to vibration or external force, and ensure the stability and accuracy of the shooting assembly during the detection process.

[0021] Further, the shooting assembly comprises a base plate, and a high-definition scanning camera is fixedly arranged on the outer wall of the bottom of the base plate. The high-definition scanning camera can capture real-time image information of the road surface, including cracks, potholes, wear and other conditions of the road surface.
