At this time, the universal wheels 402 no longer contact the ground, thereby preventing the wheels from displacing due to uneven force during the detection process and ensuring the accuracy of the detection results.

[0026] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the detection component 5 is composed of a hydraulic cylinder 501, a hydraulic rod 502, a connecting block 503, a pressure detection plate 504 and two transmission rods 505.

Before the detection is prepared, the hydraulic cylinder 501 is in a non-working state, the hydraulic rod 502 does not extend, and the side baffle 103 is in its initial position without covering the periphery of the device. When the detection starts, the hydraulic cylinder 501 starts to work, driving the hydraulic rod 502 to extend downward so that the pressure detection plate 504 contacts the road surface. At the same time, the extension of the hydraulic rod 502 will also drive the transmission rod 505 to move downward through the connecting block 503, thereby driving the side baffle 103 to move downward to cover the periphery of the device and prevent the fragments generated by the fragmentation of the road surface from splashing, thus protecting the staff from injury.

[0027] The usage method and advantages of the present utility model: When the road surface strength detection device for municipal road construction is working, the working process is as follows:

The connecting plate 401 and the universal wheels 402 start to move upward. The guide posts 403 ensure the stability of the connecting plate 401 during the rising process. As the connecting plate 401 and the universal wheels 402 rise, the four originally suspended support blocks 102 gradually approach the ground until the support blocks 102 contact the ground and support the entire device. At this time, the universal wheels 402 no longer contact the ground, thus preventing the wheels from displacing due to uneven force during the detection and ensuring the accuracy of the detection result. Before the detection is prepared, the hydraulic cylinder 501 is in a non-working state, the hydraulic rod 502 does not extend, and the side baffle 103 is in its initial position without blocking the periphery of the device. When the detection starts, the hydraulic cylinder 501 starts to work, driving the hydraulic rod 502 to extend downward so that the pressure detection plate 504 contacts the road surface. At the same time, the extension of the hydraulic rod 502 will also drive the transmission rod 505 to move downward through the connecting block 503, and then drive the side baffle 103 to move downward to block the periphery of the device and prevent the fragments generated by the road surface fragmentation from splashing, thereby protecting the staff from injury.
