[0004] Based on the above patent, by replacing the wheels of the vehicle with rollers, the punching machine can correspond to the weight of different vehicles during punching, and can quickly detect the concrete pavement inside the groove. After the concrete pavement poured inside the groove suffers extreme damage, not too much concrete will be wasted, which saves materials and improves the efficiency of detection.

Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a concrete pavement damage detection device, which is convenient for testing the device with simulated rollers of more diameters and improves the stability of the cement slab during detection.

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

[0007] A concrete pavement damage detection device comprises a device housing, wherein the two right parts of the front end of the device housing are fixedly connected to a driving motor, the driving ends of the driving motors are fixedly connected to a worm, the outer wall of the worm opposite to one end is meshedly connected to a worm wheel, the rear end of the worm wheel is fixedly connected to a transmission rod, the rear end of the transmission rod is fixedly connected to a transmission gear, the outer wall of the transmission gear is meshedly connected to a rack plate, the left end of the rack plate is fixedly connected to a connecting frame, the inner wall of the connecting frame is connected to a simulated roller through a replacement component, the rear end of the connecting frame is slidably connected to an auxiliary sliding rod, and the left and right sides of the bottom end of the inner wall of the device housing are connected to clamping claws through a clamping component;
