Description

Technical Field

[0001] The invention belongs to the technical field of road surface detection devices, in particular to a road surface flatness detection device for bridge construction. Background Art

[0002] After the construction of the bridge is completed, it is necessary to use a flatness tester to test the road surface of the bridge to ensure the flatness of the bridge road surface. Existing flatness testers are mostly used in conjunction with a test vehicle and a data test box. The test vehicle collects data on the road surface and then transmits the collected data to the data test box, making it convenient for staff to observe in real time.

[0003] A Chinese patent application CN114427822B discloses an integrated device for detecting road surface flatness for bridge construction. The movement of the equipment can not only achieve the effect of preliminary compaction of the road surface ahead, improve the overall bearing strength of the road surface after leveling, and increase the service life of the road surface, but also can use the rolling of the roller combined with the chemical reaction detection method. Compared with the traditional detection method, it is not only simpler and more intuitive, but also more accurate, and the detection process saves time and effort, greatly improving the detection efficiency.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the flatness tester is used in the northern winter, due to the low temperature in the north, the road surface will be iced and there will be a lot of snow on the road surface. It is difficult for traditional flatness testers to quickly clear ice and snow. When the rollers run on the surface of the ice, the influence of the ice will cause the entire vehicle body to become uneven, which will cause the flatness tester to easily detect erroneous data when detecting the flatness of the road surface, making it difficult for staff to obtain the accurate data they need.

[0005] To this end, the present invention provides a road surface smoothness detection device for bridge construction. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: a road surface leveling detection device for bridge construction described in the present invention comprises a detection vehicle and a roller, the bottom of the detection vehicle is rotatably connected to the roller, the top of the detection vehicle is provided with a data detection box, the bottom of the detection vehicle is fixedly installed with a detector, and the top of the data detection box is hinged with a box cover; a rectangular box is fixedly installed at one end of the detection vehicle, a plurality of electric push rods are fixedly installed on the top of the rectangular box directly in front of the roller, the bottom of the electric push rods is slidably connected to an output rod, the top of the rectangular box is provided with a cavity running through the box, the output rod is in the cavity, the bottom of the output rod is fixedly installed with a conical ice-breaking rod, the side wall of the ice-breaking rod is slidably connected to an insert block, and the bottom of the insert block is rotatably connected to a rotating wheel, The surface of the rotating wheel is fixedly installed with a protrusion; when the flatness tester is used in the winter in the north, the temperature in the north is too low in winter, the road surface will be iced, and there will be a lot of snow on the road surface. It is difficult for traditional flatness testers to quickly clean the ice and snow. When the rollers walk on the surface of the ice, the entire vehicle body will be uneven due to the influence of the ice, which will cause the flatness tester to easily detect erroneous data when detecting the flatness of the road surface, making it difficult for staff to obtain the required accurate data. When the present invention is working, when the detection vehicle starts to move, the detector follows the detection vehicle to move, and the detector will transmit the detected data to the data detection box through the data cable in real time, and display it through the display on the data detection box, so as to facilitate observation by the staff. Start the electric push rod on the top of the rectangular box, and let the output rod of the electric push rod move toward the ground with the ice-breaking rod, plug block and rotating wheel. At this time, the protrusions on the ice-breaking rod, plug block and rotating wheel will continuously hit the ice on the ground, and the plug block and rotating wheel will first contact the ice, which will play a role in pre-contact and crushing the ice before the roller moves, reducing the roller walking on the ice layer, causing inaccuracy in data detection. At the same time, when encountering ice that is too hard, the plug block will slide in the ice-breaking rod, causing the plug block to move with the ice-breaking rod toward the output rod, thereby playing a buffering and protecting role of the plug block and rotating wheel, making it convenient for the subsequent ice-breaking rod to continue to crush the ice, so that the detector on the detection vehicle can detect the correct data, reducing the occurrence of inaccurate detection data due to ice on the road.

[0008] Preferably, the rectangular box is provided with a plurality of rectangular grooves communicating with the cavity, the rectangular grooves are pre-installed with water and heating wires, the surface of the output rod is fixedly sleeved with a slide plate, the rectangular groove is provided with a bellows, the upper and lower ends of the bellows are respectively fixedly connected to the bottom surface of the rectangular groove and the bottom surface of the slide plate, the side walls of the bellows are sealingly and slidably connected to the rectangular groove, a closed space is formed between the side walls of the rectangular groove and the bellows, a top rod is fixedly installed at the bottom of the slide plate, a water outlet pipe is provided at the bottom of the rectangular groove, an elastic rope is fixedly connected to the inside of the water outlet pipe, a blocking block is slidably connected to the inside of the water outlet pipe, and the other end of the elastic rope is fixedly connected to the blocking block; during operation, when the output rod of the electric push rod moves, it will move with the slide plate and the bellows, and the bellows The corrugated tube prevents the loss of water in the rectangular groove and starts the heating wire in the rectangular groove to heat the water in the rectangular groove. When the slide plate is continuously moving up and down, it will use the water pressure and the push rod to intermittently push open the blocking block in the water outlet pipe, so that the hot water in the rectangular groove can be sprayed out intermittently, thereby assisting the melting of ice on the ground, thereby accelerating the melting of ice and facilitating the measurement work of the inspection vehicle. At the same time, the intermittent spraying of water is controlled by the work of the electric push rod, and there is no need to set up a water spray control structure separately, which simplifies the internal structure of the entire device. At the same time, when the electric push rod drives the slide plate to slide up and down, it will also promote the stirring and mixing of the water flow inside the rectangular groove, so that the heating wire can quickly and evenly heat the stored water in the rectangular groove, thereby improving the melting effect of the subsequent water flow on the ice layer.

[0009] Preferably, a plurality of arc-shaped guide blocks are fixedly mounted on the surface of the push rod, and a through hole is opened on the surface of the guide block, and fan blades are rotatably connected inside the through hole; when the push rod is in operation, when pushing open the blocking block, the arc-shaped guide blocks on the surface will guide the water flow, and at the same time, the fan blades on the guide block will start to rotate due to the impact of the water flow, and then discharge the hot water to a distance, so that the hot water can accelerate the melting of the ice cubes around.

[0010] Preferably, a connecting plate is fixedly installed on the bottom of the rectangular box, and the connecting plate is in a "human" shape. The connecting plate is located directly in front of the roller; when working, the connecting plate installed at the front end of the roller pushes impurities such as stones in front of the detection vehicle, and the "human" shaped connecting plate can guide the ice cubes to the surroundings, thereby reducing the debris directly in front of the roller, thereby reducing the probability of the detection vehicle detecting erroneous data.

[0011] Preferably, a "U"-shaped clamping plate is fixedly installed on one side of several electric push rods close to each other, and the inner wall of the clamping plate is provided with a groove, and a connecting shaft is slidably connected inside the groove, and a ball is rotatably connected to the middle part of the connecting shaft, and a rubber column is fixedly connected to the inside of the groove, and the other end of the rubber column is fixedly connected to the shaft of the ball; when working, the detection vehicle puts the data detection box between the two clamping plates before moving, and the data detection box will contact the ball in the groove, and the ball plays an auxiliary guiding role, so that the data detection box can slide into the clamping plate smoothly, and the data detection box squeezes the ball, so that the ball and the rubber column are deformed. When the data detection box enters the clamping plate and is installed, the rubber column and the ball are reset, so that the ball is above the data detection box, thereby shielding the data detection box and preventing the data detection box from easily detaching from the clamping plate. It can also play a better buffering role when vibrating up and down, so that the data detection box can cooperate with the detection vehicle to work more stably.

[0012] Preferably, a fixing block of rubber material is fixedly installed on the top of the box cover, a welding plate is fixedly installed on the top of the splint, a hollow connecting frame is fixedly installed on one side of the welding plate, a hollow elastic block is fixedly installed inside the connecting frame, an air pipe is fixedly installed on one side of the elastic block, and the air pipe passes through the connecting frame and extends to the top of the data detection box; during operation, after the data detection box is installed, the box cover of the data detection box is opened, so that the fixing block on the box cover enters the connecting frame, thereby playing the role of fixing the box cover. Since the data detection box works outdoors, there will be snow and dust on the surface of the data detection box. When the box cover of the data detection box is closed, the box cover and the fixing block are excessively rotated and squeezed in the direction of the connecting frame, so that the fixing block can squeeze the elastic block in the connecting frame, so that the gas in the elastic block is blown to the surface of the data detection box through the pipe, thereby playing the role of blowing away snow and dust, facilitating and quickly closing the data detection box, and reducing damage to the parts of the data detection box after the snow melts.

[0013] Preferably, a placement slot is provided on the top of the rectangular box, a rubber box is fixedly installed inside the placement slot, salt is pre-installed inside the rubber box, a plurality of slide bars are slidably connected to the inside of the placement slot by springs, a pressure plate is fixedly installed on the top of the slide bar, a discharge port which communicates with the placement slot and the rubber box is provided at the bottom of the rectangular box, a sleeve plate with an inclined cross-section is sleeved on the surface of the slide bar, a rotating fan is rotatably connected to the bottom of the rectangular box, a motor is installed inside the rectangular box, and the output end of the motor and the rotating fan are fixedly installed; during operation, when the data detection box is placed on the splint, it will contact the pressure plate, and then move with the pressure plate and the slide bar into the placement slot, and squeeze the rubber box, so that the salt in the rubber box enters the discharge port, and the movement of the slide bar will bring the sleeve plate along At this time, the motor in the rectangular box starts to rotate with the rotating fan, and the rotating fan breaks up the flowing salt, so that the salt particles can fly around, so that the salt particles can be sprayed over a wider range, accelerating the melting of ice and snow. At the same time, when the weather is warmer and de-icing is not required, the inside of the rubber box can be left empty. When the detection vehicle is traveling on an uneven road, the data detection box shakes up and down, constantly squeezing the rubber box, and making the pressure plate and the slide bar move synchronously to drive the discharge port to open, so that the air inside the rubber box can be continuously ejected from the discharge port, which can blow and clean the impurities on the road where the detector is traveling, reducing the interference of road debris on the detection of the detector.

[0014] Preferably, the inner wall of the connecting plate is rotatably connected to a roller via an axis, and a group of annular evenly distributed storage grooves are opened on the surface of the roller along its axial direction; when working, the roller is arranged to fit the road surface, so that when the inspection vehicle is moving, the roller can roll synchronously on the fitted road surface, and the salt particles will fall into the storage groove of the roller. Since the roller rotates clockwise toward the direction of the connecting plate, the salt particles in the storage groove are continuously thrown forward, thereby melting the snow in advance, thereby facilitating the subsequent inspection work of the inspection vehicle.

[0015] Preferably, a drum membrane is fixedly installed inside the storage groove, a magnetic block is fixedly installed on the inner wall of the drum membrane, a through groove communicated with the rubber box is opened at the bottom of the rectangular box, the through groove and the axis of the drum are on the same vertical plane, a card plate is fixedly installed on one side of the slide bar, the card plate is made of magnetic material, the top of the card plate is in the through groove and can block it; when working, when the slide bar slides down, it will take the card plate out of the through groove, at this time the through groove opens, and allows the salt in the rubber box to scatter into the storage groove of the drum through the through groove, because the drum is constantly rotating, when the drum takes the drum in the storage groove When the membrane rotates to the bottom of the card plate, the magnetic block at the bottom of the membrane and the card plate repel each other, thereby driving the membrane to shrink into the storage slot, so that the storage slot can reserve more space for loading granular salt. Then, as the drum continues to rotate clockwise, and drives the magnetic block on the membrane and the card plate away from a certain distance, the membrane can bounce up instantly under the action of its own elasticity, and throw the salt particles in the storage slot more forcefully, thereby throwing the salt particles farther away, achieving a better effect of pre-melting the snow; and when the membrane bounces up, it can shake off and eject the salt particles adhered to the surface, reducing the residue and waste of salt particles.

[0016] Preferably, a connecting pipe is fixedly installed between two adjacent storage grooves, and a one-way valve is installed inside the connecting pipe, and the one-way valve can make the direction of the airflow inside the connecting pipe connected in a closed loop the same as the rotation direction of the drum; during operation, when the magnetic block approaches the card plate, the repulsive effect of the two will cause the eardrum to squeeze the gas inside the storage groove, and make the gas in the top storage groove of the drum blow to the next storage groove in the clockwise direction through the connecting pipe, thereby promoting the salt particles in the adjacent storage grooves to be thrown out more forcefully.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The road surface leveling detection device for bridge construction described in the present invention, when the detection vehicle starts to move, the detector moves with the detection vehicle, and the detector transmits the detected data to the data detection box through the data line in real time, and displays it through the display on the data detection box, so as to facilitate observation by the staff. At the same time, when encountering too hard ice, the plug will slide in the ice breaking rod, so that the plug will move with the ice breaking rod in the direction of the output rod, and then play a buffering and protective role. The plug and the rotating wheel are convenient for the subsequent ice breaking rod to continue to break the ice, so that the detector on the detection vehicle can detect the correct data, reducing the occurrence of inaccurate detection data due to ice on the road surface.

[0019] 2. The present invention relates to a road surface smoothness detection device for bridge construction. When the output rod of the electric push rod moves, it will move with the slide plate and the bellows. The bellows prevents the loss of water in the rectangular groove and starts the heating wire in the rectangular groove to heat the water in the rectangular groove, thereby accelerating the melting of ice and facilitating the measurement work of the detection vehicle. At the same time, the intermittent spraying of water is controlled by the operation of the electric push rod, and there is no need to set up a water spraying control structure separately, which simplifies the internal structure of the entire device. At the same time, when the electric push rod drives the slide plate to slide up and down, it will also promote the stirring and mixing of the water flow inside the rectangular groove, so that the heating wire can quickly and evenly heat the stored water in the rectangular groove, thereby improving the melting effect of the subsequent water flow on the ice layer.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figures 1 to 9As shown, a road surface leveling detection device for bridge construction described in an embodiment of the present invention comprises a detection vehicle 1 and a roller 2, the bottom of the detection vehicle 1 is rotatably connected to the roller 2, the top of the detection vehicle 1 is provided with a data detection box 3, the bottom of the detection vehicle 1 is fixedly installed with a detector 22, and the top of the data detection box 3 is hinged with a box cover 4; a rectangular box 5 is fixedly installed at one end of the detection vehicle 1, a plurality of electric push rods 6 are fixedly installed on the top of the rectangular box 5 directly in front of the roller 2, the bottom of the electric push rod 6 is slidably connected to an output rod 8, the top of the rectangular box 5 is provided with a cavity 7 running through the box, the output rod 8 is in the cavity 7, the bottom of the output rod 8 is fixedly installed with a conical ice-breaking rod 9, the side wall of the ice-breaking rod 9 is slidably connected to an insert block 10, and the bottom of the insert block 10 is rotatably connected to a rotating wheel 11, The surface of the rotating wheel 11 is fixedly installed with a protrusion; when the flatness detector 22 is used in the northern winter, the temperature in the north is too low in winter, the road surface will be iced, and there will be a lot of snow on the road surface. It is difficult for the traditional flatness detector 22 to quickly clean the ice and snow. When the roller 2 walks on the surface of the ice, the entire vehicle body will be uneven due to the influence of the ice, which will cause the flatness detector 22 to easily detect erroneous data when detecting the flatness of the road surface, making it difficult for the staff to obtain the required accurate data. When the present invention is working, when the detection vehicle 1 starts to move, the detection vehicle 1 moves with the detection device 22. The detection device 22 will transmit the detected data to the data detection box 3 through the data line in real time, and display it through the display on the data detection box 3, so as to facilitate observation by the staff. Start the electric push rod 6 on the top of the rectangular box 5, and let the output rod 8 of the electric push rod 6 move toward the ground with the ice-breaking rod 9, the plug block 10 and the rotating wheel 11. At this time, the protrusions on the ice-breaking rod 9, the plug block 10 and the rotating wheel 11 will continuously hit the ice on the ground, and the plug block 10 and the rotating wheel 11 will first contact the ice, which will play a role in pre-contact and crushing the ice before the roller 2 moves, thereby reducing the roller 2 walking on the ice layer, causing inaccuracy in data detection. At the same time, when encountering ice that is too hard, the plug block 10 will slide in the ice-breaking rod 9, so that the plug block 10 moves with the ice-breaking rod 9 in the direction of the output rod 8, thereby playing a buffering and protecting role. The plug block 10 and the rotating wheel 11 make it convenient for the subsequent ice-breaking rod 9 to continue to crush the ice, so that the detector 22 on the detection vehicle 1 can detect correct data, reducing the occurrence of inaccurate detection data due to ice on the road surface.

[0035] The rectangular box 5 is provided with a plurality of rectangular grooves 12 in communication with the cavity 7, the rectangular grooves 12 are pre-installed with water and heating wires, a slide plate 13 is fixedly sleeved on the surface of the output rod 8, a bellows 15 is provided inside the rectangular groove 12, the upper and lower ends of the bellows 15 are respectively fixedly connected to the bottom surfaces of the rectangular groove 12 and the bottom surfaces of the slide plate 13, the side walls of the bellows 15 are sealingly and slidably connected to the rectangular groove 12, and a closed space is formed between the side walls of the rectangular groove 12 and the bellows 15, a top rod 14 is fixedly installed at the bottom of the slide plate 13, a water outlet pipe 16 is provided at the bottom of the rectangular groove 12, an elastic rope 18 is fixedly connected to the inside of the water outlet pipe 16, a blocking block 17 is slidably connected to the inside of the water outlet pipe 16, and the other end of the elastic rope 18 is fixedly connected to the blocking block 17; when working, the output rod 8 of the electric push rod 6 will carry the slide plate 13 and The bellows 15 moves together, and the bellows 15 prevents the loss of water in the rectangular groove 12. At the same time, the heating wire in the rectangular groove 12 is started to heat the water in the rectangular groove 12. During the continuous up and down movement of the slide plate 13, the water pressure and the push rod 14 are used to intermittently push open the blocking block 17 in the water outlet pipe 16, so that the hot water in the rectangular groove 12 is sprayed out intermittently, thereby assisting the melting of ice on the ground, thereby accelerating the melting of ice and facilitating the measurement work of the detection vehicle 1. At the same time, the intermittent spraying of water flow is controlled by the work of the electric push rod 6, and there is no need to set up a water spraying control structure separately, which simplifies the internal structure of the entire device. At the same time, when the electric push rod 6 drives the slide plate 13 to slide up and down, it will also promote the stirring and mixing of the water flow inside the rectangular groove 12, so that the heating wire can quickly and evenly heat the stored water in the rectangular groove 12, thereby improving the melting effect of the subsequent water flow on the ice layer.

[0036] A plurality of arc-shaped guide blocks 19 are fixedly mounted on the surface of the push rod 14, and a through hole 20 is provided on the surface of the guide block 19, which penetrates the guide block 19, and a fan blade 21 is rotatably connected inside the through hole 20; when the push rod 14 is working, when the blocking block 17 is pushed open, the arc-shaped guide block 19 on the surface will guide the water flow, and at the same time, the fan blade 21 on the guide block 19 will start to rotate due to the impact of the water flow, and then discharge the hot water to a distance, so that the hot water can accelerate the melting of the ice cubes around.

[0037] A connecting plate 23 is fixedly installed at the bottom of the rectangular box 5, and the connecting plate 23 is in a "human" shape. The connecting plate 23 is located directly in front of the roller 2; when working, the connecting plate 23 installed at the front end of the roller 2 allows the connecting plate 23 to push impurities such as stones in front of the detection vehicle 1, and the "human" shaped connecting plate 23 can guide the ice cubes to the surroundings, thereby reducing the debris directly in front of the roller 2, thereby reducing the probability of the detection vehicle 1 detecting erroneous data.

[0038] A "U"-shaped clamping plate 24 is fixedly installed on one side where several electric push rods 6 are close to each other. A groove 25 is opened on the inner wall of the clamping plate 24. A connecting shaft is slidably connected inside the groove 25. A ball 26 is rotatably connected to the middle of the connecting shaft. A rubber column 27 is fixedly connected inside the groove 25. The other end of the rubber column 27 is fixedly connected to the shaft of the ball 26. When working, the detection vehicle 1 puts the data detection box 3 between the two clamping plates 24 before moving. The data detection box 3 will contact the ball 26 in the groove 25, and the ball 26 plays an auxiliary role. Due to the guiding effect, the data detection box 3 can slide smoothly into the clamping plate 24. The data detection box 3 squeezes the ball 26, causing the ball 26 and the rubber column 27 to deform. When the data detection box 3 enters the clamping plate 24 and is installed, the rubber column 27 and the ball 26 are reset, so that the ball 26 is above the data detection box 3, thereby shielding the data detection box 3 and preventing the data detection box 3 from easily detaching from the clamping plate 24. It can also play a better buffering role when vibrating up and down, so that the data detection box 3 can work more stably with the detection vehicle 1.

[0039] A rubber fixing block 30 is fixedly installed on the top of the box cover 4, a welding plate 28 is fixedly installed on the top of the clamping plate 24, a hollow connecting frame 29 is fixedly installed on one side of the welding plate 28, a hollow elastic block 31 is fixedly installed inside the connecting frame 29, an air pipe is fixedly installed on one side of the elastic block 31, and the air pipe passes through the connecting frame 29 and extends to the top of the data detection box 3; when working, after the data detection box 3 is installed, the box cover 4 of the data detection box 3 is opened, so that the fixing block 30 on the box cover 4 enters the connecting frame 29, thereby playing a role in fixing. The function of the fixed box cover 4 is that since the data detection box 3 works outdoors, there will be snow and dust on the surface of the data detection box 3. When closing the box cover 4 of the data detection box 3, the box cover 4 and the fixed block 30 are excessively rotated and squeezed toward the direction of the connecting frame 29, so that the fixed block 30 can squeeze the elastic block 31 in the connecting frame 29, so that the gas in the elastic block 31 is blown to the surface of the data detection box 3 through the pipe, thereby playing the role of blowing away the snow and dust, facilitating the rapid closure of the data detection box 3, and reducing the damage to the parts of the data detection box 3 after the snow melts.

[0040] A placement slot 45 is provided on the top of the rectangular box 5, a rubber box 32 is fixedly installed inside the placement slot 45, and salt is pre-installed inside the rubber box 32. A plurality of slide bars 34 are slidably connected to the inside of the placement slot 45 through a spring, and a pressing plate 33 is fixedly installed on the top of the slide bar 34. A discharge port 35 communicating with the placement slot 45 and the rubber box 32 is provided at the bottom of the rectangular box 5. A sleeve plate 36 with an inclined cross-section is sleeved on the surface of the slide bar 34, and a rotating fan 37 is rotatably connected to the bottom of the rectangular box 5. A motor is installed inside the rectangular box 5, and the output end of the motor and the rotating fan 37 are fixedly installed. During operation, when the data detection box 3 is placed on the clamping plate 24, it will contact the pressing plate 33, and then move into the placement slot 45 with the pressing plate 33 and the slide bar 34, and squeeze the rubber box 32, so that the salt in the rubber box 32 enters the discharge port 35. Due to the movement of the slide bar 34, the salt in the rubber box 32 enters the discharge port 35. The movement will bring the sleeve plate 36 to move, and then open the discharge port 35. At this time, the salt in the discharge port 35 will be guided by the inclined sleeve plate 36 and then directed to the rotating fan 37. At this time, the motor in the rectangular box 5 starts to rotate with the rotating fan 37. The rotating fan 37 breaks up the flowing salt, so that the salt particles can fly around, so that the salt particles can be sprayed over a wider range, accelerating the melting of ice and snow. At the same time, when the weather is relatively warm and no de-icing is required, the inside of the rubber box 32 can be left empty. When the detection vehicle 1 is traveling on an uneven road, the data detection box 3 shakes up and down, continuously squeezing the rubber box 32, and causing the pressing plate 33 and the sliding rod 34 to move synchronously, driving the discharge port 35 to open, so that the air inside the rubber box 32 can be continuously ejected from the discharge port 35, and the impurities on the road surface where the detector 22 is traveling can be purged and cleaned, reducing the interference of road debris on the detection of the detector 22.

[0041] The inner wall of the connecting plate 23 is rotatably connected to a roller 38, and a group of annular evenly distributed receiving grooves 39 are opened on the surface of the roller 38 along its axial direction; when working, by setting the roller 38 to fit with the road surface, the roller 38 can roll synchronously on the fitted road surface when the inspection vehicle 1 is moving, and the salt particles will fall into the receiving grooves 39 of the roller 38. Since the roller 38 rotates clockwise in the direction of the connecting plate 23, the salt particles in the receiving grooves 39 are continuously thrown forward, thereby playing the role of melting the snow in advance, and facilitating the subsequent inspection work of the inspection vehicle 1.

[0042] A drum membrane 42 is fixedly installed inside the storage groove 39, and a magnetic block 43 is fixedly installed on the inner wall of the drum membrane 42. A through groove 40 communicating with the rubber box 32 is opened at the bottom of the rectangular box 5, and the through groove 40 is on the same vertical plane as the axis of the drum 38. A card plate 41 is fixedly installed on one side of the slide bar 34, and the card plate 41 is made of magnetic material. The top of the card plate 41 is in the through groove 40 and can block it. When working, when the slide bar 34 slides down, it will take the card plate 41 out of the through groove 40. At this time, the through groove 40 is opened, and the salt in the rubber box 32 is scattered into the storage groove 39 of the drum 38 through the through groove 40. Since the drum 38 is constantly rotating, when the drum 38 is carrying When the eardrum 42 in the storage groove 39 rotates to below the card plate 41, the magnetic block 43 at the bottom of the eardrum 42 and the card plate 41 repel each other, thereby driving the eardrum 42 to shrink into the storage groove 39, so that the storage groove 39 can reserve more space for loading granular salt. Then, as the drum 38 continues to rotate clockwise and drives the magnetic block 43 on the eardrum 42 and the card plate 41 to move away from a certain distance, the eardrum 42 can bounce up instantly under the action of its own elasticity, and throw out the salt particles in the storage groove 39 more forcefully, thereby throwing the salt particles farther, achieving a better effect of pre-melting the snow; and when the eardrum 42 bounces up, it can shake off and eject the salt particles adhered to the surface, thereby reducing the residue and waste of salt particles.

[0043] Embodiment 2

[0044] like Fig.10 As shown, compared with Example 1, another embodiment of the present invention is: a connecting pipe 44 is fixedly installed between two adjacent storage grooves 39, and a one-way valve is installed inside the connecting pipe 44, and the one-way valve can make the airflow direction inside the connecting pipe 44 connected in a closed loop the same as the rotation direction of the drum 38; during operation, when the magnetic block 43 approaches the card plate 41, the repulsive effect of the two will cause the eardrum 42 to squeeze the gas inside the storage groove 39, and make the gas in the top storage groove 39 of the drum 38 be blown into the next storage groove 39 in the clockwise direction through the connecting pipe 44, thereby promoting the salt particles in the adjacent storage grooves 39 to be thrown out more forcefully.

[0045] Working principle: when the detection vehicle 1 starts to move, the detection instrument 22 moves along with the detection vehicle 1. The detection instrument 22 transmits the detected data to the data detection box 3 through the data line in real time, and displays it through the display on the data detection box 3, so as to facilitate observation by the staff. Start the electric push rod 6 on the top of the rectangular box 5, and let the output rod 8 of the electric push rod 6 move toward the ground with the ice-breaking rod 9, the plug block 10 and the rotating wheel 11. At this time, the protrusions on the ice-breaking rod 9, the plug block 10 and the rotating wheel 11 will continuously hit the ice on the ground, and the plug block 10 and the rotating wheel 11 will first contact the ice, which will play a role in pre-contact and crushing the ice before the roller 2 moves, thereby reducing the roller 2 walking on the ice layer, causing inaccuracy in data detection. At the same time, when encountering ice that is too hard, the plug block 10 will slide in the ice-breaking rod 9, so that the plug block 10 moves with the ice-breaking rod 9 in the direction of the output rod 8, thereby playing a buffering and protecting role. The plug block 10 and the rotating wheel 11 are convenient for the subsequent ice-breaking rod 9 to continue to crush the ice, so that the detector 22 on the detection vehicle 1 can detect correct data, reducing the occurrence of inaccurate detection data due to ice on the road surface. When the output rod 8 of the electric push rod 6 moves, it will move with the slide plate 13 and the bellows 15. The bellows 15 prevents the loss of water in the rectangular groove 12 and starts the heating wire in the rectangular groove 12 to heat the water in the rectangular groove 12. When the slide plate 13 moves up and down continuously, it will use the water pressure and the push rod 14 to intermittently push open the blocking block 17 in the water outlet pipe 16, so that the hot water in the rectangular groove 12 can be sprayed out intermittently, thereby assisting the melting of ice on the ground, thereby accelerating the melting of ice and facilitating the measurement work of the detection vehicle 1. At the same time, the intermittent spraying of water flow is controlled by the work of the electric push rod 6, and there is no need to set up a water spraying control structure separately, which simplifies the internal structure of the entire device. At the same time, when the electric push rod 6 drives the slide plate 13 to slide up and down, it will also promote the stirring and mixing of the water flow inside the rectangular groove 12, so that the heating wire can quickly and evenly heat the stored water in the rectangular groove 12, thereby improving the melting effect of the subsequent water flow on the ice layer. When the push rod 14 pushes open the blocking block 17, the arc-shaped guide block 19 on the surface will guide the water flow. At the same time, the fan blades 21 on the guide block 19 are impacted by the water flow and start to rotate, thereby discharging hot water to a distance, so that the hot water can accelerate the melting of the ice cubes around. The connecting plate 23 installed at the front end of the roller 2 can push the impurities such as stones in front of the detection vehicle 1. The "human"-shaped connecting plate 23 can guide the ice cubes to the surroundings, thereby reducing the debris in front of the roller 2, thereby reducing the probability of the detection vehicle 1 detecting erroneous data.Before the detection vehicle 1 moves, the data detection box 3 is first placed between the two clamping plates 24. The data detection box 3 will contact the ball 26 in the groove 25. The ball 26 plays an auxiliary guiding role, so that the data detection box 3 can slide smoothly into the clamping plate 24. The data detection box 3 squeezes the ball 26, causing the ball 26 and the rubber column 27 to deform. When the data detection box 3 enters the clamping plate 24 and is installed, the rubber column 27 and the ball 26 are reset, so that the ball 26 is above the data detection box 3, thereby shielding the data detection box 3 and preventing the data detection box 3 from easily detaching from the clamping plate 24. It can also play a better buffering role when vibrating up and down, so that the data detection box 3 can work more stably with the detection vehicle 1. After installing the data detection box 3, open the box cover 4 of the data detection box 3 so that the fixing block 30 on the box cover 4 enters the connecting frame 29, thereby fixing the box cover 4. Since the data detection box 3 works outdoors, there will be snow and dust on the surface of the data detection box 3. When closing the box cover 4 of the data detection box 3, the box cover 4 and the fixing block 30 are excessively rotated and squeezed toward the connecting frame 29, so that the fixing block 30 can squeeze the elastic block 31 in the connecting frame 29, so that the gas in the elastic block 31 is blown to the surface of the data detection box 3 through the pipe, thereby blowing away the snow and dust, facilitating the rapid closure of the data detection box 3, and reducing the damage to the parts of the data detection box 3 after the snow melts. When the data detection box 3 is placed on the clamping plate 24, it will contact the pressing plate 33, and then move the pressing plate 33 and the sliding rod 34 into the placement groove 45, and squeeze the rubber box 32, so that the salt in the rubber box 32 enters the discharge port 35. The movement of the sliding rod 34 will move the sleeve plate 36 together, and then open the discharge port 35. At this time, the salt in the discharge port 35 will be guided by the inclined sleeve plate 36 and then guided to the rotating fan 37. At this time, the motor in the rectangular box 5 starts to rotate with the rotating fan 37, and the rotating fan 37 breaks up the falling salt, so that the salt particles can fly around, thereby allowing The salt particles are sprayed over a wider range, accelerating the melting of ice and snow. At the same time, when the weather is relatively warm and de-icing is not required, the rubber box 32 can be left empty. When the detection vehicle 1 is traveling on an uneven road, the data detection box 3 is shaken up and down, continuously squeezing the rubber box 32, and causing the pressing plate 33 and the sliding rod 34 to move synchronously, driving the discharge port 35 to open, so that the air inside the rubber box 32 can be continuously ejected from the discharge port 35, and impurities on the road surface where the detector 22 is traveling can be blown away, reducing the interference of road debris on the detection of the detector 22.By setting the roller 38 to fit the road surface, the roller 38 can roll synchronously on the fitting road surface when the inspection vehicle 1 is moving, and the salt particles will fall into the storage groove 39 of the roller 38. Since the roller 38 rotates clockwise in the direction of the connecting plate 23, the salt particles in the storage groove 39 are continuously thrown forward, thereby playing the role of melting the snow in advance, and facilitating the subsequent inspection work of the inspection vehicle 1. When the slide bar 34 slides down, it will take the card plate 41 out of the through groove 40. At this time, the through groove 40 opens and allows the salt in the rubber box 32 to scatter into the storage groove 39 of the roller 38 through the through groove 40. Since the roller 38 is constantly rotating, when the roller 38 rotates with the eardrum 42 in the storage groove 39 to the bottom of the card plate 41, the magnetic block 43 at the bottom of the eardrum 42 and the card plate 41 repel each other, thereby driving the eardrum 42 to shrink into the storage groove 39, so that the storage groove 39 can More space is reserved for loading granular salt. Then, as the drum 38 continues to rotate clockwise and drives the magnetic block 43 on the eardrum 42 and the card plate 41 to move away to a certain distance, the eardrum 42 can bounce up instantly under the action of its own elasticity, and throw out the salt particles in the storage groove 39 more forcefully, thereby throwing the salt particles farther away, achieving a better effect of pre-melting the snow; and when the eardrum 42 bounces up, it can shake off and eject the salt particles adhered to the surface, thereby reducing the residue and waste of salt particles.
