[0004] When using a radar thickness gauge to inspect asphalt pavement, inspectors need to frequently bend over to pick up and place the gauge, which increases the labor intensity of the inspectors and affects the efficiency of the inspection. Therefore, an asphalt paving thickness measuring device is proposed to address the above problem. Utility Model Content

[0005] The purpose of the utility model is to provide an asphalt paving thickness measuring device to solve the problems raised in the above background technology.

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

[0007] An asphalt paving thickness measuring device comprises a detection frame and a radar thickness gauge arranged inside the detection frame, and further comprises:

[0008] The traction assembly includes a guide rod fixedly connected to the center of the top frame plate of the detection frame, an extension rod slidably plugged into the top open end of the guide rod, and a traction seat fixedly connected to the top of the extension rod.

[0016] It can be seen from the technical solution provided by the utility model above that the asphalt paving thickness measuring device provided by the utility model has the following beneficial effects:

[0017] 1. By installing the radar thickness gauge on the inner side of the detection frame, when the asphalt pavement thickness detection is needed, the detection personnel lift and move the detection frame through the traction seat. When it reaches the detection point, the traction seat is lowered horizontally. The casters first contact the ground and continue to apply pressure. The buffer pads of the support are attached to both sides of the detection point. Then, pressure is applied again, and the reset spring A undergoes elastic deformation until the detection frame of the radar thickness gauge is attached to the detection point. Then, the radar thickness gauge can be used for detection. The detection process is smooth and labor-saving, which reduces the workload of the detection personnel and improves the detection efficiency.

[0018] 2. After completing the inspection of the designated position, remove the longitudinal pressure on the traction seat. Under the elastic force of the reset spring A, the detection frame with the radar thickness gauge is separated from the detection point and a gap is generated. Under the elastic force of the reset spring B, the bottom of the detection seat is separated from the detection point, and the casters are in contact with the asphalt ground. When the next detection point needs to be inspected, a horizontal thrust is applied to the traction seat. With the assistance of the casters, the radar thickness gauge is driven to move, and the moving process is labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS
