Description

Although different countries have different names for expressways, they all refer to highways with more than 4 lanes, two-way separation, full control of entrances and exits, and all use grade separations. In addition, in many regions, direct trunk lines with partially controlled entrances and exits and not all use grade separations are also called expressways. At present, the total mileage of domestic expressways has exceeded 50,000 kilometers. With the rapid development of the national economy and the surge in the number of cars, the traffic safety situation of domestic expressways is very severe.

After the detection is completed, force is applied to the limit cylinder to pull the rectangular block out from the inside of the rectangular groove, which is convenient The completed drawings are taken out for convenience. After the inspection is completed, the flatness of the road surface can be checked, and the drawings can also be included afterwards for timely retrieval when problems arise in the future. At the same time, a cleaning component is added, in which the cleaning brush and bevel gear G can be used in cooperation. When the positioning column on the same side of the bevel gear C rotates, it will drive the bevel gear F to rotate. The bevel gears C and F will cause the two bevel gears G to rotate, thereby driving the two positioning rods to rotate inside the positioning cylinder, driving the two cleaning brushes to rotate. The two cleaning brushes will clean up the gravel and debris on the ground due to the rotation, preventing the detection wheel from pressing on the debris, resulting in detection errors, thereby causing unnecessary workload.

[0027] The working principle and use process of the present invention are as follows: when it is necessary to inspect the flatness quality of the highway pavement, one end of the drawing paper is passed through the limit frame A213 and fits together on the surface of the winding shell A28, and then the handle 222 is pulled to make the connecting rod 221 slide inside the slide groove 220. The limit block 223 will slide the limiting rod 219 inside the positioning hole due to its shape, so that the tooth block 217 slides out from the inside of the tooth groove 216, thereby releasing the limit on the ratchet rod 29, and then the handle 222 is pushed to make the winding shell A28 rotate on the surface of the fixed platform 11, and the drawing paper is wound on the surface of the winding shell A28. After winding to an appropriate length, the other end of the drawing paper is passed through the limit frame B214 and fits together with the winding shell B212, and the limit frame A 213 and the limit frame B214 are used to prevent the drawing position of the drawing from changing due to the change of the winding diameter when the drawing is wound. When the ratchet rod 29 rotates, the ratchet teeth 210 cooperate with the ratchet rod 29 due to their shapes, so that the ratchet teeth 210 will slide inside the positioning hole, which makes it convenient to roll up the drawing without moving the fixed platform 11. Then, the handle 222 is released, and the spring C224 will push the tooth block 217 back to the inside of the tooth groove 216 due to the elastic potential energy, so as to limit the ratchet rod 29. Then, the drawing pen is placed inside the positioning hole A31, with the pen tip facing the drawing. Then, the bolt 32 is turned to squeeze and limit the drawing pen, so as to prevent the drawing pen from shaking when the fixed platform 11 moves. Drop it, then pour the marking paint into the inside of the pigment shell 114, place the fixed platform 11 on the road surface that needs to be tested, the detection wheel 16 will cause the limit rod 15 to slide inside the through hole due to resistance, so that the detection wheel 16 is close to the ground, and the motor 22 is connected to the external power supply and then started, and the bevel gear A23 will drive the positioning column 13 to rotate inside the fixed block A12 through the bevel gear B24, so that the roller 14 rotates on the ground, thereby moving the fixed platform 11, and the rotation of the bevel gear B24 will drive the limit column B227 to rotate through the bevel gear E215, thereby driving the winding shell B212 to rotate, and the drawing will be wound on the surface of the winding shell B212. When the fixed platform 11 moves, it will push the roller 14 to rotate, thereby driving the bevel gear C25 to rotate through the positioning column 13. When the winding shell B212 is rotated, the ratchet rod 29 is driven to rotate through the bevel gear D26 and the limit column A27. Because the tooth block 217 and the ratchet tooth 210 limit the ratchet rod 29, the winding shell A28 is driven to rotate, so that the winding shell B212 and the winding shell A28 rotate at the same frequency, preventing the winding shell A28 from rotating due to inertia when the winding shell B212 stops rotating. The ratchet tooth 210 has a connection between the ratchet rod 29 and the winding shell A28, making the connection more stable. When the winding shell B212 rolls up the drawing, the drawing pen will draw on the drawing because the drawing pen fits the drawing. Because the limit rod 15 will move up and down with the drawing pen due to the unevenness of the road surface, the straightness of the road surface can be drawn on the drawing surface.When the detection is completed, force is applied to the limit cylinder 226 to pull the rectangular block 225 out from the inside of the rectangular groove, so that the completed drawing can be taken out. After the detection is completed, the flatness of the road surface can be checked, and the drawings can also be collected afterwards, so that timely retrieval can be made when problems arise in the future. When the road surface is surveyed and mapped, the detection wheel 16 will contact the uneven road surface to cause the limit rod 15 to move inside the through hole until the road surface protrusion is more obvious, the fixing rod A17 will be moved upward, the positioning rod A18 will rotate on the surface of the fixing rod B19, the positioning rod B110 will slide inside the limiting groove A111 through the sliding shaft, and at the same time, the positioning rod B110 will move the fixing shell 112 toward the ground, the brush wheel 113 will contact the ground and roll on the ground, and the marking paint inside the pigment shell 114 will be applied to the ground through the rolling of the brush wheel 113. The brush wheel 113 will not move away from the road surface until the detection wheel 16 moves to a road surface with a small undulation. This can provide the staff with a clear view of the surface where the road surface flatness is extremely poor. The brush wheel 113 is relatively absorbent, and the through holes inside the pigment shell 114 and the fixed shell 112 are relatively small, which makes it difficult for the marking paint to drip from the inside of the fixed shell 112. The spring A115 can make the detection wheel 16 close to the ground. When the positioning column 13 on the same side of the bevel gear C25 rotates, it will drive the bevel gear F36 to rotate. The bevel gears C25 and F36 will cause the two bevel gears G37 to rotate, thereby driving the two positioning rods to rotate inside the positioning cylinder 34, driving the two cleaning brushes 35 to rotate. The two cleaning brushes 35 will clean the gravel and debris on the ground due to the rotation, preventing the detection wheel 16 from pressing on the debris, resulting in errors in the detection, thereby causing unnecessary workload.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
