Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0012] A road and bridge construction flatness measuring device, such as Figure 1-5As shown, it includes a horizontal plate 1, and walking wheels 2 are respectively arranged at the four corners of the bottom surface of the horizontal plate 1. Several sleeves 3 arranged from front to back are arranged on the horizontal plate 1. A measuring mechanism is arranged in the sleeve 3, and a marking mechanism is arranged at the bottom end of the sleeve 3. The measuring mechanism measures the unevenness of the ground, and the components in the marking mechanism work to mark the unevenness. A debris guide mechanism is arranged on one side of the horizontal plate 1. The debris guide mechanism is a prior art, so it will not be described in detail. A pusher is arranged on the top surface of the other side of the horizontal plate 1. Pushing the horizontal plate 1 to move drives the sleeve 3 to move, and the measuring mechanism in the sleeve 3 measures the flatness of the road surface. When the unevenness is measured, the marking mechanism starts to work and marks the unevenness for subsequent repair. Moreover, through several measuring mechanisms, a full range of measurements can be performed in an area at the same time to avoid omissions.

[0013] Specifically, the measuring mechanism described in this embodiment includes a vertical rod 4 that can move up and down inside the sleeve 3, a plug rod 5 is arranged on the inner wall of the top end of the sleeve 3, a slot is provided on the top end of the vertical rod 4, and the plug rod 5 can be inserted into the slot, a spring 6 is arranged between the top end of the vertical rod 4 and the inner wall of the bottom end of the sleeve 3, and the plug rod 5 passes through the spring 6, and a measuring wheel 7 is arranged at the bottom end of the vertical rod 4, a through slot 8 is provided on one side of the sleeve 3, and a metering plate 9 is arranged on one side of the vertical rod 4, and the metering plate 9 passes through the through slot 8, and an infrared rangefinder is arranged on one side of the sleeve 3, and the infrared rangefinder measures the distance moved by the metering plate 9. When the measuring wheel 7 walks on the road surface, when walking on an uneven place, such as a depression on the ground, the measuring wheel 7 falls down, the vertical rod 4 moves down, the metering plate 9 moves down, and the infrared rangefinder measures the distance moved downward by the metering plate 9, on the contrary, when the ground bulges, the measuring wheel 7 moves up, and by moving a plurality of measuring wheels 7 arranged front and back in the area below the horizontal plate 1, the ground in this area can be measured more comprehensively to avoid omissions.

[0014] Furthermore, the marking mechanism described in this embodiment includes a circular ring 10 arranged at the bottom end of the sleeve 3, a first annular groove 11 is opened at the bottom end of the circular ring 10, a cavity is arranged in the circular ring 10, a gear ring 12 is arranged in the cavity, a second annular groove 13 is opened on the inner wall at the top end of the cavity, a plurality of moving blocks are arranged in the second annular groove 13, a connecting block is arranged at the bottom end of the moving block, the bottom end of the connecting block is connected to the top end of the gear ring 12, a marking pen 14 is arranged on one side of the bottom end of the gear ring 12, the marking pen 14 passes through the first annular groove 11, a motor is arranged at the top end of the cavity, a gear is arranged at the bottom end of the output shaft of the motor, and the gear is in the gear ring 12 and meshes with the gear ring 12. The ring 10 is colinear with the vertical center line of the sleeve 3, and the moving block always moves in the second annular groove 13.
