[0004] With respect to the above-mentioned related technologies, the applicant believes that a type of transportation engineering inspection equipment, when working, utilizes a cleaning roller installed at the front end of the device to rotate and clean up debris on the road section to be inspected, so as to ensure the actual flatness of the inspected road surface. However, during use, it was found that the dust, debris, stones, etc. on the road surface can be swept away under the high-speed rotation of the cleaning roller, but the cleaned debris, dust, stones, etc. will be swept away and fly around.

In addition, the flying dust, stones, etc. seriously affect the safety of the inspectors when inspecting the road surface. Utility Model Content
[0005] The purpose of the utility model is to provide a transportation engineering detection device to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a transportation engineering inspection equipment, comprising: an inspection vehicle and a cleaning structure; an air duct is welded at one end of the inspection vehicle; the cleaning structure is arranged at one end of the inspection vehicle, and the cleaning structure comprises a fixed column welded to the lower surface of the inspection vehicle platform, a cleaning roller rotatably connected to the inner side of the fixed column, a motor connected to the upper surface of the inspection vehicle by a fixed frame, a belt transmission connected to the motor shaft, a blower disk connected to the upper surface of the inspection vehicle by bolts, and an air supply pipe welded to the exhaust port of the blower disk, the other end of the air supply pipe is welded to the outer wall of the air duct, and one end of the rotating shaft of the motor is welded to the fan blade inside the blower disk.
[0007] By adopting the above technical solution, an air duct is welded to one end of the inspection vehicle, and a motor is used to drive the blower plate and the cleaning roller to operate at the same time. The cleaning roller sweeps debris into the air duct, and the blower plate generates strong wind force to enter the air duct through the air duct, blowing the debris out from the other end. The device can not only clean the debris, but also use the wind force to blow the debris to a distant side, thereby reducing the degree of dust dispersion on the inspection section and improving the accuracy of the data for checking the flatness of the road surface.
[0008] Preferably, a detection structure is provided on the lower surface of the platform of the detection vehicle, and the detection structure includes a telescopic column inserted on the detection vehicle platform, a spring inserted on the outer wall of the telescopic column, a moving wheel connected to the bottom of the telescopic column by screws, a detection platform welded on the outer wall of the moving wheel, and a laser ranging head threadedly connected to the detection platform.
[0009] By adopting the above technical scheme, the laser distance measuring head in the prior art is fixedly installed in a way that is changed to being fixed on a telescopic column that can be extended and retracted by a spring. The bottom moving wheel contacts the road surface and rolls on roads with different flatness. The telescopic column will be extended and retracted according to the flatness, so that the laser distance measuring head in the middle position is always at a fixed value. The laser distance measuring heads on both sides measure the distance on both sides of the moving wheel to obtain the road surface flatness. This structure can avoid the problem that the laser distance measuring head of the detection vehicle cannot ensure uniform horizontal plane detection due to uneven road surface, thereby improving the accuracy of the road surface flatness detection data.
[0010] Preferably, the platform of the inspection vehicle is provided with an active hole, and the inspection platform and the laser ranging head are located directly below the active hole.
[0011] By adopting the above technical solution, by opening an active hole just above the detection table, the data line connected to the laser distance measuring head can be inserted through the active hole. When the telescopic column is extended and retracted due to different road surface flatness, it can be ensured that the laser distance measuring head can maintain a good state to avoid the data line being too long and folding the laser distance measuring head.
[0012] Preferably, the detection structures and movable holes are provided in three groups, and three groups of laser ranging heads are equidistantly provided on the upper surfaces of the three groups of detection platforms.
[0013] By adopting the above technical solution, three groups of detection structures are set up to evenly cover three groups of detection points on the detected road surface, thereby increasing the detection data and improving the diversity of the detection data. At the same time, the three groups of laser ranging heads can move in height with the telescopic column during detection, so that the laser ranging head in the middle position always maintains a detection fixed value. The laser ranging heads on both sides detect the heights on both sides for comparison, and the local accuracy here can be accurately obtained. By combining the three groups of detection structures, the flatness of the road surface within the horizontal line can be obtained.
[0014] Preferably, the main body of the air duct is in the shape of a semicircular tube, one side of the cleaning roller is located inside the air duct, and a curtain is attached to the bottom of the air duct.
[0015] By adopting the above technical solution and designing the air duct into a semicircular tube shape, one side of the cleaning roller can be sealed on one side of the semicircular tube to form a relatively closed space. When the cleaning roller rotates at a high speed, the effect of dust, gravel and other materials entering the air duct can be improved, and the influence of gravel and dust on the ranging accuracy can be reduced. At the same time, the bottom of the air duct is covered with a curtain to avoid the problem of scratches on uneven roads caused by the low bottom of the air duct, and to ensure the dispersion of dust at the bottom.
[0016] Preferably, soft bristles are evenly distributed on the outer wall of the cleaning roller, the bristles at the bottom of the cleaning roller bend when they abut against the ground, and the cleaning roller at one end of the belt rotates clockwise with reference to it.
[0017] By adopting the above technical solution, by using longer bristles, the bristles can be bent and pressed on the road surface, which can improve the ability to clean road dust and stones, and control the cleaning roller to rotate clockwise, which can drive dust and stones into the bottom of the air duct, avoiding the problem of reverse rotation and sweeping dust to the rear inspection personnel.
[0018] Preferably, a PLC controller is provided on the upper surface of the inspection vehicle, and the input and output ends of the laser ranging head and the motor are electrically connected to the output end of the PLC controller.
[0019] By adopting the above technical solution, the motor can be conveniently controlled by installing a PLC controller. At the same time, the ranging signals transmitted by different groups of laser ranging heads can be received for analysis, and the numerical value of the road surface flatness can be finally obtained, which is convenient for the inspection personnel to record and operate.
[0020] Preferably, the length from the top of the telescopic column to the bottom of the moving wheel is greater than the height of the roller of the inspection vehicle, and the spring is in a compressed state.
[0021] By adopting the above technical solution and designing the length of the telescopic column and the moving wheel, under the action of the spring in the compressed state, it can be ensured that the moving wheel can be pressed against the road surface on roads with different flatness, so as to ensure normal detection of the three groups of laser ranging heads.
[0022] Compared with the prior art, the beneficial effects of the utility model are:
[0023] (1) By welding an air duct to one end of the inspection vehicle, a motor is used to drive the blower disc and the cleaning roller to operate simultaneously. The cleaning roller sweeps debris into the air duct, and the blower disc generates strong wind to enter the air duct through the air duct and blow the debris out from the other end. The device can not only clean the debris, but also use the wind to blow the debris to a far side, thereby reducing the degree of dust drifting on the inspection section and improving the accuracy of the road surface flatness inspection data;
[0024] (2) By using the power source of the cleaning roller to drive the blower disc to generate wind, the air duct can blow the discharged dust, stones and other materials from the other side to a remote place, so that the dust can be scattered and the stones can be splashed away from the inspectors, thereby improving the safety of the inspection environment for the inspectors;
[0025] (3) The telescopic column is fixed by using a spring to extend and retract. The bottom moving wheel contacts the road surface and rolls on roads with different flatness. The telescopic column will extend and retract according to the flatness, so that the laser distance measuring head in the middle is always at a fixed value. The laser distance measuring heads on both sides measure the distance on both sides of the moving wheel to obtain the road surface flatness. This structure can avoid the problem that the laser distance measuring head cannot ensure uniform horizontal plane detection due to uneven road surface, thereby improving the accuracy of road surface flatness detection data.

[0040] Embodiment 3
[0041] See also Figures 1 to 5The main body of the air guide tube 2 is in the shape of a semicircular tube, and one side of the cleaning roller 302 is located on the inner side of the air guide tube 2. By designing the air guide tube 2 into a semicircular tube shape, the cleaning roller 302 can be located on one side of the semicircular tube to be sealed to form a relatively closed space. When the cleaning roller 302 rotates at a high speed, the effect of dust, stones and other substances entering the air guide tube 2 can be improved, and the influence of stones and dust on the distance measurement accuracy can be reduced. A curtain is attached to the bottom of the air guide tube 2. The bottom of the air guide tube 2 is blocked by the curtain, which can prevent the bottom of the air guide tube 2 from being too low and encountering an uneven road surface. The problem of scratching is solved, and the dust at the bottom is also ensured to be dispersed. The outer wall of the cleaning roller 302 is evenly distributed with soft bristles. The bristles at the bottom of the cleaning roller 302 bend when they touch the ground, and the cleaning roller 302 at one end of the belt 304 is used as a reference to rotate clockwise.

In addition, the cleaning roller 302 is controlled to rotate clockwise, which can drive dust and stones into the bottom end of the air guide pipe 2, avoiding the problem of reverse rotation sweeping dust to the rear inspection personnel.
[0042] See also Figures 1 to 5 A PLC controller 6 is provided on the upper surface of the detection vehicle 1. The input and output ends of the laser ranging head 505 and the motor 303 are electrically connected to the output end of the PLC controller 6. By installing the PLC controller 6, it is convenient to control the motor 303. At the same time, it can also receive the ranging signals transmitted by different groups of laser ranging heads 505 for analysis, and finally obtain the value of the road surface flatness, which is convenient for the detection personnel to record and operate. The length from the top of the telescopic column 501 to the bottom of the moving wheel 503 is greater than the roller height of the detection vehicle 1, and the spring 502 is in a compressed state. By designing the length of the telescopic column 501 and the moving wheel 503, under the action of the compressed spring 502, it can be ensured that the moving wheel 503 can be pressed on the road surface on roads with different flatness, so as to ensure the normal detection of the three groups of laser ranging heads 505.
[0043] Working principle: When in use, the motor 303 drives the blast plate 305 and the cleaning roller 302 to operate at the same time. The cleaning roller 302 sweeps debris into the air duct 2. The blast plate 305 generates a strong wind force to enter the air duct 2 through the air duct 306, and blow the debris out from the other end. The wind force is used to blow the debris to a far side, thereby reducing the degree of dust drifting on the detection section, and making the dust drifting and stone splashing directions away from the detection personnel, thereby improving safety. The telescopic column 501 that is retracted and extended by the spring 502 is fixed, and the bottom moving wheel 503 contacts the road surface and rolls on roads with different flatness. The telescopic column 501 will be retracted and extended according to the flatness, so that the laser distance measuring head 505 in the middle position is always at a fixed value, and the laser distance measuring heads 505 on both sides measure the distance on both sides of the moving wheel 503.
