Problems solved by technology

[0003] The existing horizontal measurement method needs to test the vertical and horizontal directions when performing measurements. Usually, the transmitting transducer and the receiver need to be fixed on the same straight line, but there is often an offset due to manual fixation of the transmitting transducer The situation of the horizontal line, so the measurement results have a large deviation, so we propose a highway roadbed pavement damage detection device

Embodiment 1

[0031] combine figure 1 , 2 , 5 and 6, the present invention proposes a highway subgrade pavement damage detection device, including a fixed slide rail 100, a transmitter support frame 200 and a launch transducer 300, and the fixed slide rail 100 is negatively reset on the On the road surface, the launcher support frame 200 is suitable for sliding relative to the fixed slide rail 100 and is assembled on the fixed slide rail 100, and the launch transducer 300 is installed on the launcher support frame 200, along with the launcher The support frame 200 moves.

[0032] Specifically, before the detection, the fixed slide rail 100 is negatively reset on the road surface to be tested by stones or other counterweights, so as to ensure the stability of the fixed slide rail 100 during detection. The test is carried out in the vertical and horizontal directions on the cement concrete, the transmitting transducer 300 is fixed, the receiver is placed on the same straight line, and a poi...

Embodiment 2

[0037] combine figure 1 , 4 As shown, the fixed slide rail 100 includes a first guide rail 110, a second guide rail 120 and a splicing structure 130 for assembling the first guide rail 110 and the second guide rail 120. The splicing structure 130 includes a The trapezoidal block 133 at the joint of the first guide rail 110, the trapezoidal card slot 134 arranged at the joint of the second guide rail 120 and suitable for sliding relative to the trapezoidal block 133, and the second guide rail 120 passing through and fixed on the fixing piece 135 of the trapezoidal block 133 .

[0038]Specifically, in order to facilitate the carrying of the fixed slide rail 100, the fixed slide rail 100 is split into a first guide rail 110 and a second guide rail 120, and when in use, the first guide rail 110 and the second guide rail 120 are assembled through the splicing structure 130 , the specific assembly process is to align the trapezoidal block 133 with the trapezoidal slot 134, insert ...

Embodiment 3

[0042] combine image 3 As shown, the folding part includes a rotating part 240, an extension plate 250 and a clamping part 260, the extending plate 250 is connected to the arc-shaped pillar 230 through a rotating part 240, and the clamping part 260 is connected to the arc-shaped pillar 230 through another The rotating part 240 is connected to the extension plate 250, the emitting transducer 300 is fixed on the clamping part 260, and its emitting end is vertically downward, and the arc-shaped pillar 230 is close to one of the emitting transducers 300. There is a semicircular storage slot on the side, and the transmitting transducer 300 is folded into the storage slot by the folding piece when it is not working;

[0043] Since the transmitter support frame 200 is large in size, it is inconvenient to transport, so it is necessary to fold the transmitter support frame 200 so that the extension plate 250 and the emission transducer 300 are folded into the semicircular storage slot...
