[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0031] See also Figure 1-9 , the present invention provides a technical solution: Embodiment 1

[0032] A municipal road inspection vehicle comprises: an inspection vehicle body 1, the inspection vehicle body 1 comprises a road inspection trolley 11, a front shovel frame 12 is arranged at the front position of the road inspection trolley 11, and a snow shovel 13 is arranged at the other end of the front shovel frame 12.

[0033] It also includes a regulating mechanism 2, which is arranged between the front and rear wheels on the chassis of the road measuring trolley 11, and the regulating mechanism 2 is used to simulate the effect of the vehicle rolling over the road after snow shoveling;

[0034] The snow road slip measuring mechanism 4 is arranged on the regulating mechanism 2, and the regulating mechanism 2 controls the snow road slip measuring mechanism 4 to contact with the road surface after snow is shoveled, and simulates the slip measuring data of wheels at different angles;

[0035] The salt spreading mechanism 3 is arranged at the rear of the road slip measuring vehicle 11, and the salt spreading mechanism 3 is controlled by the data detected by the snow road slip measuring mechanism 4 to control the amount of salt spreading according to the degree of road slip.

[0036] On the road after a heavy snowstorm, a road inspection vehicle is needed to detect the road surface slip data for reference for safe driving of other vehicles. First, the snow on the road is cleared by the snow shovel 13 at the front end of the road slip detection vehicle 11. At the same time, the remaining snow on the road after clearing is crushed by the control mechanism 2 to simulate the road after the vehicle is crushed, which is more conducive to the snow road slip detection mechanism 4 to detect the road side slip data, and the snow road slip detection mechanism 4 is adjusted to contact with the road surface through the control mechanism 2, so as to detect the road surface. At the same time, the detection data of the snow road slip detection mechanism 4 is transmitted to the vehicle system for reference by the salt spreading mechanism 3. The greater the degree of road slip, the more salt is spread by the salt spreading mechanism 3, which is conducive to reducing the side slip of the road.

[0037] The regulating mechanism 2 includes a downward extending frame 21 fixedly connected to the chassis of the road measuring trolley 11, and a snow-pressing wheel 22 is rotatably connected to the bottom end of the downward extending frame 21, and the snow-pressing wheel 22 has the same ground clearance as the four wheels, and the centerline position of the snow-pressing wheel 22 is aligned with the centerline of the road measuring trolley 11. The road measuring trolley 11 clears the snow on the road while crushing the remaining snow on the road with the snow-pressing wheel 22, simulating the road after the residual snow on the road surface is crushed by the vehicle, which is more conducive to the snow road skid measuring mechanism 4 to detect the data of road skid.

[0038] A limiting side groove 24 is provided on one side of the lower extending frame 21 close to the rear of the vehicle, a lifting groove 25 is provided inside the limiting side groove 24, a force-bearing frame 26 is provided inside the lifting groove 25, and rotating columns 27 rotatably connected to the limiting side groove 24 are fixedly provided on both sides of the force-bearing frame 26, and the force-bearing frame 26 is rotatably connected to the lower extending frame 21 through the rotating columns 27.

[0039] A regulating frame 23 is fixedly provided at one end of the force-bearing frame 26 near the rear end of the vehicle, and a pneumatic push rod 28 fixedly connected to the downward extending frame 21 is rotatably provided at the center position of one end of the force-bearing frame 26 near the front end of the vehicle, a slide rail groove 201 is provided on the inner side of the regulating frame 23, and an angular adjustment opening 29 is provided at the center position of the slide rail groove 201. When it is necessary to perform a slip test on the road, the pneumatic push rod 28 is used to push the end of the force-bearing frame 26 near the front end of the vehicle upward, and the regulating frame 23 near the rear end of the vehicle is turned downward, so that the simulated wheel 44 of the snow road slip measuring mechanism 4 is in contact with the ground, thereby detecting the slip degree of the road, and the weight of the simulated wheel 44 can be simulated by applying different pressures of the pneumatic push rod 28 to the force-bearing frame 26. Embodiment 2

[0040] The snow road skid measuring mechanism 4 includes a regulating disk 41, a slide rail body 43 is fixedly provided on the outer wall of the regulating disk 41, an inclined plate 49 is fixedly provided at the top center position of the regulating disk 41, and a pneumatic push rod 2 401 is rotatably provided on one side of the inclined plate 49. The angle of the simulation wheel 44 can be adjusted by pushing the inclined plate 49 by the pneumatic push rod 2 401, so that different angles of the simulation wheel 44 can simulate the angle of the tire of the vehicle when changing lanes or turning, which is conducive to more realistic detection of road side slip data. When the pneumatic push rod 2 401 pushes the inclined plate 49, it can drive the regulating disk 41 to slide along the slide rail groove 201, thereby adjusting the angle of the simulation wheel 44, and the slide rail body 43 slides along the slide rail groove 201 to ensure the stability of the rotation of the regulating disk 41.

[0041] A pressure-relieving groove 42 is provided inside the regulating disk 41, and a simulation wheel 44 is arranged near the rear of the vehicle. A rotating column plate 45 is arranged inside the simulation wheel 44 for rotation, and a sliding pressure plate 46 is fixedly arranged on the top of the rotating column plate 45. When the simulation wheel 44 contacts the road surface, the simulation wheel 44 rotates as the vehicle moves forward. When the road surface slips, the simulation wheel 44 will slip and stop rotating. At the same time, the simulation wheel 44 will slide backwards while slipping, squeezing or pulling the tension sensor 48, so that the data of road skidding can be detected.

[0042] The upper and lower walls of the sliding pressure plate 46 are fixedly provided with friction films 47. The sliding pressure plate 46 slides along the pressure relief groove 42 and can only slide in one direction. The friction films 47 can increase the resistance of the sliding pressure plate 46 to ensure that the sliding pressure plate 46 is in the center position when the road side slip is small. A tension sensor 48 is fixedly provided inside the sliding pressure plate 46, and the telescopic columns at both ends of the tension sensor 48 are both inserted into the sliding pressure plate 46. The tension sensor 48 is connected to the control system of the road measuring trolley 11 through a wire. When the tension sensor 48 detects the road side slip data, it can be transmitted to the vehicle system. Embodiment 3

[0043] The salt spreading mechanism 3 includes a salt storage bin 31 fixedly connected to the road measuring trolley 11, and a grain suction pipe 32 fixedly connected to the tail position and obliquely connected is provided at the output end of the salt storage bin 31, and an air flow channel 34 is fixedly provided at the other end of the grain suction pipe 32, and a plurality of spreading pipes 33 are provided at the output end of the air flow channel 34, and the spreading pipe 33, the air flow channel 34 and the grain suction pipe 32 are interconnected.

[0044] The input end of the air flow channel 34 is fixedly connected with a high-pressure air pipe 35, and the other end of the high-pressure air pipe 35 is provided with an air supply device connected to the road measuring trolley 11, and the air supply device is connected to the system of the road measuring trolley 11 through a wire. When salt needs to be spread, the high-pressure gas is injected into the high-pressure air pipe 35 through the air outlet end of the air pump of the air supply device, and the air in the high-pressure air pipe 35 flows from right to left. The high-speed flowing gas can drive the salt particles in the salt storage bin 31 to enter the air flow channel 34 along the direction of the air flow, and finally sprayed onto the road surface through the spreading pipe 33. Because the salt particles in the salt storage bin 31 are sprayed out under the drive of the air flow, the gas can also flow out from the spreading pipe 33 at the same time, which is conducive to spraying the salt particles more messily.

[0045] A material control assembly 36 is rotatably arranged in the output port of the particle suction tube 32. The material control assembly 36 is composed of a plurality of material control sheets 37 of fan-shaped structure. The sizes of the plurality of material control sheets 37 gradually decrease from the outside to the inside. The ends of two adjacent material control sheets 37 are connected with elastic films 38. The elastic films 38 are provided with a plurality of expansion columns 301 which are interconnected. An air guide hose 39 is connected to the input end of the expansion column 301, and the other end of the air guide hose 39 is connected to the air pump outlet end of the air supply device in the road skid measuring vehicle 11. When the road side slip data detected by the snow road skid measuring mechanism 4 is small, the air supply device can be controlled by the system to supply air to the air guide hose 39. After the air enters the air guide hose 39, it can be expanded, thereby opening the folded material control sheets 37 and reducing the amount of salt particles entering the air flow channel 34, which is beneficial to control the amount of road salting according to the degree of road side slip.
