Detailed implementation mode

[0020] The present utility model will be specifically described below with reference to the accompanying drawings.

[0021] A road evenness detection device, as Figures 1 - 3 shown, includes a base 1, universal wheels 2, a detector 3, a cleaning rack 4, a pushing rack 5, a connecting rack 6, a placing rack 7 and a fixing mechanism 8. Two left and right universal wheels 2 are rotatably connected to the front and rear parts of the base 1, which is convenient for movement. A detector 3 is connected to the upper side of the base 1. A cleaning rack 4 is connected to the upper right part of the base 1. A pushing rack 5 is connected to the left part of the base 1. A connecting rack 6 is slidably connected to the pushing rack 5. A placing rack 7 is rotatably connected to the connecting rack 6. A fixing mechanism 8 for adjusting the height is provided between the pushing rack 5 and the connecting rack 6.

[0022] As Figure 1 and Figure 3 shown, the fixing mechanism 8 includes a support block 81, a limiting rack 82, a first telescopic spring 83, a guide rod 84, a fixing frame 85 and a second telescopic spring 86. A support block 81 is connected to the front side of the connecting rack 6. A limiting rack 82 is slidably connected to the support block 81. The limiting rack 82 is clamped with the pushing rack 5 and the connecting rack 6. A first telescopic spring 83 is connected between the limiting rack 82 and the support block 81. A guide rod 84 is connected to the upper right part of the support block 81. A fixing frame 85 is slidably connected to the guide rod 84. The fixing frame 85 is in clamping cooperation with the limiting rack 82. A pull ring is provided on the upper left part of the fixing frame 85, which is convenient for holding and pulling the fixing frame 85. A second telescopic spring 86 is connected between the fixing frame 85 and the guide rod 84.

[0023] As Figure 1 、 Figure 4 and Figure 5 shown, it further includes a protection mechanism 9. The protection mechanism 9 includes a support frame 91, a dust-proof cover 92, a torsion spring 93 and a shielding plate 94. A support frame 91 is connected to the right side of the placing rack 7. A dust-proof cover 92 is rotatably connected to the support frame 91. The dust-proof cover 92 is made of a transparent material, which is convenient for viewing. Two left and right torsion springs 93 are connected between the dust-proof cover 92 and the support frame 91. A shielding plate 94 is rotatably connected to the dust-proof cover 92.

[0024] When it is necessary to detect the road smoothness, this device can be used. Bring this device to the place where the road smoothness needs to be detected, so that the universal wheels 2 are in contact with the ground. Rotate the dust cover 92 and the baffle 94 to open, and the torsion spring 93 deforms. Then place the touch display screen into the placement rack 7, and then release the dust cover 92. The torsion spring 93 rotates and restores, and the dust cover 92 rotates and resets, thereby dust-proofing the touch display screen. The dust cover 92 is made of transparent material for easy viewing.

Then rotate the placement rack 7 to adjust to a suitable angle. Then pull the fixed frame 85 through the pull ring, so that the fixed frame 85 moves upward along the guide rod 84, and the second telescopic spring 86 is compressed, so that the fixed frame 85 is disengaged from the limiting frame 82. Then pull the limiting frame 82 by hand, and the first telescopic spring 83 is compressed. Then pull the connecting frame 6 up and down by hand. After moving to a suitable position, release the limiting frame 82, and the first telescopic spring 83 rebounds, and the limiting frame 82 moves back to its original position and is clamped with the push frame 5. Release the pull ring, and the second telescopic spring 86 rebounds, and the fixed frame 85 moves back to its original position and is clamped with the limiting frame 82, so that the connecting frame 6 can be fixed.

Subsequently, the detector 3 can be started, and then push this device to move by hand holding the push frame 5, so that the universal wheels 2 rotate, thereby driving the detector 3 to move to detect the road smoothness. During the movement, the cleaning frame 4 pushes away the garbage or sundries. The detected data will be displayed on the display screen, which is convenient for operation and data reading. After the detection is completed, just turn off the detector 3.
