[0002] In the construction, operation and maintenance of expressways, the status of multiple quality indicators of roads needs to be improved, and the requirements for pavement flatness are getting higher and higher. With the rapid progress and development of society, people's living standards are getting higher and higher, and cars have become a common consumer product. The flatness of the pavement affects the service life of cars and also plays an important role in the safety of people and vehicles. According to the highway engineering quality inspection and evaluation standards formulated by the Ministry of Transport of China, one detection point is set every 100 meters at a distance of 200 meters. During detection, a 3-meter long ruler is used and measured continuously five times, that is, measured ten times per 100 meters; in actual detection, most of the time, an operator places a straight ruler on the ground for detection, observes the gap between the long ruler and the ground, and takes the maximum gap value of each detection; due to the excessive number of detections, it consumes the physical strength of the operator, and observing the gap for a long time causes visual fatigue and is prone to misjudgment, affecting the detection value.

The elastic force of the third spring pushes the cover plate 322 and the rubber pad 323 downward, so that the rubber pad 323 abuts against the tank mouth of the storage tank 310, ensuring the airtightness of the storage tank 310.

[0056] Such as Figure 15-19As shown in the figure, the marking mechanism includes a marking housing 40 and a support frame 420. A second connecting pipe 410 is used to connect the material taking pipe 321 and the marking housing 40. The support frame 420 is fixedly arranged on the wall of the detection housing 240. A first guide wheel 421 is installed on the support frame 420. There are two first guide wheels 421 arranged vertically. Second guide wheels 423 are installed on the walls of the accommodation housing 230 and the marking housing 40. A retaining disc 430 is arranged inside the marking housing 40. A pull rope 422 is connected to the top of the retaining disc 430. The pull rope 422 is wound between the second guide wheels 423 and the two first guide wheels 421 and fixedly connected to the wall of the first connecting column 251. A discharge pipe 440 is connected to the bottom of the marking housing 40. A one-way valve 425 is arranged inside the discharge pipe 440. A communicating cylinder 434 is vertically arranged at the bottom of the marking housing 40. The communicating cylinder 434 is a cylindrical housing with a closed top and an open bottom. The bottom of the communicating cylinder 434 is connected to the discharge pipe 440. A guiding column 435 is arranged on the wall of the communicating cylinder 434. The guiding column 435 is close to the top of the communicating cylinder 434. A connecting sleeve 432 is fitted on the communicating cylinder 434. A guiding groove 433 is formed on the wall of the connecting sleeve 432. The guiding groove 433 is a spiral groove. The guiding column 435 extends into the guiding groove 433. A liquid discharge hole 436 is formed on the wall of the communicating cylinder 434. The liquid discharge hole 436 is close to the bottom of the communicating cylinder 434. The retaining disc 430 is fixedly sleeved on the connecting sleeve 432. When there are bumps or concave surfaces on the road surface, the first connecting column 251 moves upward or downward, thereby driving the pull rope 422 to pull the retaining disc 430 upward. During the upward movement of the retaining disc 430, the connecting sleeve 432 moves upward along the communicating cylinder 434, so that the connecting sleeve 432 is separated from the liquid discharge hole 436 on the wall of the communicating cylinder 434. The marking liquid in the marking housing 40 can be discharged into the discharge pipe 440 through the liquid discharge hole 436, and then discharged through the discharge pipe 440, so as to make color marks on the bumps and concave surfaces of the road surface.

[0057] More specifically, a plurality of paddles 431 are arranged on the top of the retaining disc 430. During the process of the pull rope 422 pulling the retaining disc 430 upward, the guiding column 435 drives the connecting sleeve 432 to rotate, thereby driving the retaining disc 430 to rotate. During the rotation of the retaining disc 430, the paddles 431 can stir the marking liquid, so as to prevent the marking liquid from solidifying.

[0058] More specifically, a first drainage channel 327 and a second drainage channel 328 are formed on the rubber pad 323. The first drainage channel 327 is connected to the first connecting pipe 140. The second drainage channel 328 is connected to the first drainage channel 327. The drainage outlet of the second drainage channel 328 is inclined towards the pipe wall of the material taking pipe 321. When the first connecting pipe 140 is connected to the water supply pipe, the pipe wall of the material taking pipe 321 can be cleaned.

[0059] Working principle:

[0060] During the use of the present invention, the first motor 122 drives the first lead screw 124 to rotate, thereby driving the first displacement vehicle body 10 and the second displacement vehicle body 110 to approach each other, so as to adjust the distance between the first displacement vehicle body 10 and the second displacement vehicle body 110. When detecting the flatness of the road surface, the fifth motor 231 drives the detection housing 240 to rotate, so that the detection housing 240 extends out of the accommodation housing 230 and is in a vertical state. The third motor 221 can drive the accommodation housing 230 to move downwards, so that the detection wheel 257 contacts the road surface. The first spring is in a compressed state. The first displacement vehicle body 10 and the second displacement vehicle body 110 drive the detection mechanism 20 to move on the road surface. When there is a protrusion on the road surface, the protrusion abuts against the first connecting column 251 and moves it upwards. The rack 253 drives the seventh gear 256 to rotate, thereby driving the turntable 255 to rotate counterclockwise. Then, the convex block 258 faces the second sensor 260, and the second sensor 260 emits an induction signal. When there is a concave surface on the road surface, the elastic force of the first spring pushes the first connecting column 251 downwards. The rack 253 drives the seventh gear 256 to rotate, thereby driving the turntable 255 to rotate clockwise. Then, the convex block 258 faces the first sensor 259, and the first sensor 259 emits an induction signal, so as to detect the road surface. When there are protrusions and concave surfaces on the road surface, the first connecting column 251 moves up and down, thereby driving the pull rope 422 to pull the baffle plate 430 upwards. During the upward movement of the baffle plate 430, the connecting sleeve 432 moves upwards along the communicating column body 434, so that the connecting sleeve 432 is separated from the liquid discharge hole 436 in the wall of the communicating column body 434. The marking liquid in the marking housing 40 can be discharged into the discharge pipe 440 through the liquid discharge hole 436, and then discharged through the discharge pipe 440, so as to perform color marking on the road surface protrusions and concave surfaces, which is convenient for the staff to observe. During the process of the pull rope 422 pulling the baffle plate 430 upwards, the guiding column 435 drives the connecting sleeve 432 to rotate, thereby driving the baffle plate 430 to rotate. During the rotation of the baffle plate 430, the paddle 431 can stir the marking liquid, so as to prevent the marking liquid from solidifying. When installing the material taking pipe 321, lift the pressing plate 153, place the storage tank 310 on the top of the first displacement vehicle body 10, then place the material taking pipe 321 in the storage tank 310, and then loosen the pressing plate 153. The elastic force of the second spring pulls the pressing plate 153 downwards, and the bottom of the material taking pipe 321 contacts the bottom of the storage tank 310. The elastic force of the third spring pushes the cover plate 322 and the rubber pad 323 downwards, so that the rubber pad 323 abuts against the tank mouth of the storage tank 310, ensuring the tightness of the storage tank 310.
