Description

Technical Field

[0001] This invention belongs to the field of unmanned aerial vehicle (UAV) technology, specifically relating to a UAV device for highway maintenance and inspection. Background Technology

[0002] Drones are unmanned aerial vehicles that can fly autonomously without human control. They typically consist of a fuselage, battery, motor, sensors, and other necessary equipment. Drone flight control can be achieved through pre-set waypoints, remote control, or autonomous flight software.

[0003] Drones have a wide range of practical applications. In road maintenance, existing drones are often used for video data acquisition and visual inspection of the road surface to identify defects in the road or highway facilities and record their coordinates to facilitate specific maintenance work. However, in current highway maintenance, drones are often only used to detect road defects and lack practical implementation capabilities. In the highway environment, the coordinates of defects may be far from the maintenance location. Long-distance maintenance work consumes a lot of manpower and resources and affects the timeliness of defect maintenance, so improvements are needed.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

The drone body includes a fuselage, wings are mounted on both sides of the fuselage, output motors are mounted on the front and rear ends of the wings, and blades are mounted on the output ends of the output motors. A depth camera is mounted on the front end of the fuselage, and an assembly mechanism is mounted on the bottom end of the drone body. The assembly mechanism is adapted to the filling mechanism and the maintenance mechanism.

[0007] Filling mechanism: It is installed at the bottom of the drone body and adjusts its position based on the drone body. Based on its own structure, it can fill the filler and output spraying function, thereby filling the defect location.

[0012] As a further embodiment of the present invention: a hopper is fixedly installed on the lower surface of the first connecting plate, a lower support frame and a discharge hose are installed on the lower surface of the hopper, a pump is installed at the end of the discharge hose, a linkage frame is installed on the outer surface of the pump, and a first electric telescopic rod is rotatably connected between the lower support frame and the linkage frame.

[0013] As a further aspect of the present invention: the output end of the pump is equipped with a feeding pipe, the end of the feeding pipe is equipped with a fusion chamber, the rear end of the fusion chamber is equipped with an air volume regulating valve, the surface of the air volume regulating valve is equipped with an air filter, and the front end of the fusion chamber is equipped with an atomizing nozzle.

[0014] As a further aspect of the present invention: a steering motor is mounted on the lower surface of the second connecting plate, and a flipping mechanism and an adjusting arm are provided at the bottom end of the steering motor. The flipping mechanism includes an outer guide rail, a drive frame is symmetrically slidably connected to the inner side of the outer guide rail, a bidirectional screw is driven to the inner side of the outer guide rail, the bidirectional screw is threaded to the drive frame, a drive shaft is driven to the inner side of the drive frame, and the adjusting arm includes a flipping shaft. Both ends of the flipping shaft are provided with drive grooves, and the drive shaft is inserted into the inner side of the drive grooves.

[0015] As a further embodiment of the present invention: the outer surface of the flipping shaft is equipped with a second electric telescopic rod, wherein one set of the flipping mechanism is fixedly connected to the output end of the steering motor, wherein another set of the flipping mechanism is fixedly connected to the output end of the second electric telescopic rod, wherein the output end of the other set of the second electric telescopic rod is equipped with a clamping drive mechanism.

[0016] As a further aspect of the present invention: the clamping drive mechanism includes a primary motor, the primary motor being fixedly connected to the output end of another set of second electric telescopic rods, the output end of the primary motor being equipped with a secondary motor, the outer surface of the secondary motor being equipped with a six-way guide rail, the output end of the secondary motor being equipped with a drive disk, the inner side of the six-way guide rail being circumferentially and equidistantly connected with a slider, the surface of the slider being equipped with a clamping frame, the inner side of the clamping frame being rotatably connected with a linkage plate, and the linkage plate being rotatably connected to the drive disk.

[0017] A method for using a highway maintenance and inspection drone includes the following steps:

[0018] When conducting patrol missions, the main body of the drone operates through the output motor, which drives the blades to rotate. In conjunction with the wing structure, this achieves the lifting and driving effect of the fuselage. Based on the operation of the depth camera, it achieves the monitoring and visual inspection functions during the patrol mission.

[0019] During takeoff and landing, the landing gear contacts the ground. During descent, the landing gear transmits vibrations to the movable shaft, causing the movable shaft to slide inside the hollow cylinder. At this time, based on the elastic force of the buffer spring and the shock-absorbing spring, the vibration is buffered, thereby protecting the fuselage and its assembly, filling or maintenance mechanisms.

[0020] During the assembly of the filling or maintenance mechanism, the rotation trajectory of the opening and closing plate is limited by the central frame, and the lifting frame is driven by the operation of the electric drive screw in a threaded manner, so that the lifting frame moves up and down. During the process, the opening and closing plate is subjected to force based on the connecting shaft, which drives several sets of buckles to move, so that the buckles are inserted into the locking frame of the first or second connecting plate, thereby achieving the automated assembly effect of the filling or maintenance mechanism.

[0021] When road filling or painting is required, a filling mechanism is assembled, and the corresponding filler is filled into the hopper. The extension and retraction of the first electric telescopic rod, in coordination with the linkage frame, causes the pump to rotate along the lower support frame. The output angle of the pump is adjusted, and the filler is pumped out through the pump and sent into the fusion chamber through the feeding pipe. The fusion chamber adjusts the air intake based on the air volume regulating valve. During the air entering the fusion chamber, air impurities are filtered by the air filter. The air and filler are mixed inside the fusion chamber, and the material is sprayed through the atomizing nozzle. Based on the properties of the filler, the functions of filling gaps or spraying paint are realized.

[0022] Before assembling the maintenance mechanism, based on actual work needs, assemble an appropriate number of flipping mechanisms and adjusting arms. The outer guide rail drives the bidirectional screw to rotate, which in turn drives the two sets of drive frames to move in opposite directions. This allows the drive shaft to be placed inside the drive slot, and the drive frame can then drive the drive shaft to rotate, thereby controlling the flipping shaft to flip. By assembling the corresponding number of flipping mechanisms and adjusting arms, the bending flexibility and counterweight of the maintenance mechanism can be adjusted.

[0023] In the operation of the maintenance mechanism, the drive frame drives the rotating shaft to rotate, and the second electric telescopic rod extends and retracts to adjust the position of the clamping drive mechanism. The clamping drive mechanism drives the drive disk to rotate through the operation of the secondary motor. During the rotation of the drive disk, multiple sets of linkage plates are driven synchronously, which in turn drives the slider to move along the six-way guide rail trajectory, realizing the synchronous opening and closing function of multiple sets of clamping frames. The clamping frame clamps the bolt, and the primary motor ultimately drives the bolt to rotate, achieving the specific maintenance effect.

[0024] Beneficial effects:

[0025] While the main body of the drone can perform specific inspections and defect detection of road defects, the assembly structure enables automated assembly of filling and maintenance mechanisms. Based on the actual defect situation, the filling or maintenance mechanism is assembled. When the filling mechanism is assembled, the corresponding filler is filled into the hopper to achieve the effect of road filling and painting. When the maintenance mechanism is assembled, an appropriate number of flipping mechanisms and adjusting arms can be assembled based on the consideration of counterweight and flipping flexibility. When the loose road sign bolts are detected, the position of the clamping drive mechanism is adjusted based on the coordinated operation of the flipping mechanism and the adjusting arm, and the bolt tightening function is realized based on the operation of the clamping drive mechanism. This allows the drone to automatically perform corresponding maintenance work when it detects road defects, reducing the loss of manpower and material resources and improving the timeliness of maintenance work.

[0026] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0040] like Figures 1 to 3As shown, a highway maintenance and patrol drone device includes a drone body 1, a filling mechanism 2, and a maintenance mechanism 3. The drone body 1 includes a fuselage 101, wings 102 are mounted on both sides of the fuselage 101, output motors 103 are mounted on the front and rear ends of the wings 102, blades 104 are mounted on the output ends of the output motors 103, a depth camera 105 is mounted on the front end of the fuselage 101, and an assembly mechanism is mounted on the bottom end of the drone body 1. The assembly mechanism is adapted to the filling mechanism 2 and the maintenance mechanism 3.

[0041] Filling mechanism 2: It is installed at the bottom of the drone body 1 and adjusts its own position based on the drone body 1. Based on its own structure, it can fill the filler and output spraying function, thereby filling the defect position.

[0042] Maintenance mechanism 3: It is mounted on the bottom of the drone body 1 and adjusts its own position based on the drone body 1. Based on its own structure, it can achieve functions such as bolt tightening and road sign maintenance.

[0043] While the main body of the UAV 1 performs the specific inspection and defect detection functions for road defects, it also achieves the automated assembly functions of the filling mechanism 2 and the maintenance mechanism 3 through the operation of the assembly structure. Based on the actual defect situation, the filling mechanism 2 or the maintenance mechanism 3 is assembled. When the filling mechanism 2 is assembled, the corresponding filler is filled based on the material bin 202 to achieve the road surface filling and painting effect. When the maintenance mechanism 3 is assembled, based on the consideration of counterweight and tilting flexibility, an appropriate number of tilting mechanisms and adjusting arms can be assembled. When the loose road sign bolts are detected, the position of the clamping drive mechanism is adjusted based on the coordinated operation of the tilting mechanism and the adjusting arm, and the bolt tightening function is achieved based on the operation of the clamping drive mechanism. This allows the UAV to automatically perform corresponding maintenance work when it detects road defects, reducing the loss of manpower and material resources and improving the timeliness of maintenance work. When conducting inspection tasks, the main body of the UAV 1 operates through the output motor 103, which drives the blades 104 to rotate. In conjunction with the wing structure 102, the lifting and driving effect of the fuselage 101 is achieved. Based on the operation of the depth camera 105, the monitoring and visual inspection functions in the inspection task are achieved.

[0044] Specifically, such as Figure 4 As shown, both sides of the fuselage 101 are equipped with a vibration damping mechanism. The vibration damping mechanism includes a hollow cylinder 106, a movable shaft 107, and a landing gear 108. The top of the movable shaft 107 is slidably connected to the inside of the hollow cylinder 106, and the bottom of the movable shaft 107 is fixedly connected to the landing gear 108. A buffer spring 109 and a shock-absorbing spring 110 are symmetrically installed on the outer surface of the movable shaft 107. Both the buffer spring 109 and the shock-absorbing spring 110 are fixedly installed on the inside of the hollow cylinder 106.

[0045] During the takeoff and landing of the fuselage 101, the landing gear 108 contacts the ground. During landing, the landing gear 108 transmits vibrations to the movable shaft 107, causing the movable shaft 107 to slide inside the hollow cylinder 106. At this time, based on the elastic force of the buffer spring 109 and the shock-absorbing spring 110, the vibration is buffered, thereby protecting the fuselage 101 and its assembly filling mechanism 2 or maintenance mechanism 3.

[0046] Specifically, such as Figures 1 to 5 As shown, the assembly mechanism includes a central frame 111, with an opening and closing plate 112 rotatably connected to the outer end of the central frame 111 at equal intervals. A buckle 113 is installed at the bottom end of the opening and closing plate 112. An electric drive screw 114 is driven to the center position of the lower surface of the central frame 111. A lifting frame 115 is threadedly connected to the outer surface of the electric drive screw 114. A connecting shaft 116 is rotatably connected to the outer surface of the lifting frame 115. The connecting shaft 116 is rotatably connected to the opening and closing plate 112. The filling mechanism 2 and the maintenance mechanism 3 respectively include a first connecting plate 201 and a second connecting plate 301. A positioning frame is installed on the upper surface of both the first connecting plate 201 and the second connecting plate 301. The positioning frame is sleeved on the outer surface of the buckle 113.

[0047] During the assembly of filling mechanism 2 or maintenance mechanism 3, the rotation trajectory of opening and closing plate 112 is limited by center frame 111, and the lifting frame 115 is driven by the operation of electric drive screw 114 in a threaded manner, so that the lifting frame 115 moves up and down. During the process, force is applied to opening and closing plate 112 by connecting shaft 116, which drives several sets of buckles 113 to move, so that buckles 113 are inserted into the positioning frame of first connecting plate 201 or second connecting plate 301, thereby achieving the automated assembly effect of filling mechanism 2 or maintenance mechanism 3.

[0048] Specifically, such as Figure 6 As shown, a hopper 202 is fixedly installed on the lower surface of the first connecting plate 201. A lower support frame 203 and a discharge hose 204 are installed on the lower surface of the hopper 202. A pumping pump 205 is installed at the end of the discharge hose 204. A linkage frame 206 is installed on the outer surface of the pumping pump 205. A first electric telescopic rod 207 is rotatably connected between the lower support frame 203 and the linkage frame 206. A feeding pipe 208 is installed at the output end of the pumping pump 205. A fusion chamber 209 is installed at the end of the feeding pipe 208. An air volume regulating valve 210 is installed at the rear end of the fusion chamber 209. An air filter 211 is installed on the surface of the air volume regulating valve 210. An atomizing nozzle 212 is installed at the front end of the fusion chamber 209.

[0049] When road filling or painting is required, the filling mechanism 2 is installed, and the corresponding filler is filled into the hopper 202. The extension and retraction of the first electric telescopic rod 207 cooperates with the linkage frame 206 to make the pumping pump 205 rotate along the lower support frame 203. The output angle of the pumping pump 205 is adjusted, and the filler is discharged through the operation of the pumping pump 205 and sent into the fusion chamber 209 through the feeding pipe 208. The fusion chamber 209 adjusts the air intake based on the air volume regulating valve 210. During the process of air entering the fusion chamber 209, air impurities are filtered by the air filter 211. The air and filler are mixed inside the fusion chamber 209, and the spraying is performed through the atomizing nozzle 212. Based on the properties of the filler, the functions of filling gaps or spraying paint are realized.

[0050] Specifically, such as Figure 7 As shown, a steering motor 302 is mounted on the lower surface of the second connecting plate 301. A flipping mechanism and an adjusting arm are provided at the bottom end of the steering motor 302. The flipping mechanism includes an outer guide rail 303. A drive frame 305 is symmetrically slidably connected to the inner side of the outer guide rail 303. A bidirectional screw 304 is driven to the inner side of the outer guide rail 303. The bidirectional screw 304 is threaded to the drive frame 305. A drive shaft 306 is driven to the inner side of the drive frame 305. The adjusting arm includes a flipping shaft 307. Both ends of the flipping shaft 307 are provided with drive slots. The drive shaft 306 is inserted into the inner side of the drive slots. A second electric telescopic rod 308 is mounted on the outer surface of the flipping shaft 307. One set of flipping mechanisms is fixedly connected to the output end of the steering motor 302. Another set of flipping mechanisms is fixedly connected to the output end of the second electric telescopic rod 308. The output end of the other set of second electric telescopic rods 308 is equipped with a clamping drive mechanism.

[0051] Before assembling the maintenance mechanism 3, based on actual working needs, assemble an appropriate number of flipping mechanisms and adjusting arms. The outer guide rail 303 drives the bidirectional screw 304 to rotate, which in turn drives the two sets of drive frames 305 to move in opposite directions. This allows the drive shaft 306 to be placed inside the drive groove, and the drive frame 305 can then drive the drive shaft 306 to rotate, thereby controlling the flipping shaft 307 to flip. By assembling the corresponding number of flipping mechanisms and adjusting arms, the bending flexibility and counterweight of the maintenance mechanism 3 can be adjusted.

[0052] Specifically, such as Figure 8As shown, the clamping drive mechanism includes a primary motor 309, which is fixedly connected to the output end of another set of second electric telescopic rods 308. The output end of the primary motor 309 is equipped with a secondary motor 310. The outer surface of the secondary motor 310 is equipped with a six-way guide rail 311. The output end of the secondary motor 310 is equipped with a drive disk 312. The inner side of the six-way guide rail 311 is circumferentially and equidistantly connected with a slider 313. The surface of the slider 313 is equipped with a clamping frame 314. The inner side of the clamping frame 314 is rotatably connected with a linkage plate 315. The linkage plate 315 is rotatably connected to the drive disk 312.

[0053] In the operation of maintenance mechanism 3, the drive frame 305 drives the rotating shaft 307 to rotate, and the second electric telescopic rod 308 extends and retracts to adjust the position of the clamping drive mechanism. The clamping drive mechanism drives the drive disk 312 to rotate through the operation of the secondary motor 310. During the rotation of the drive disk 312, multiple sets of linkage plates 315 are driven synchronously, thereby driving the slider 313 to move along the trajectory of the six-way guide rail 311, realizing the synchronous opening and closing function of multiple sets of clamping frames 314. The clamping frame 314 clamps the bolt, and the operation of the primary motor 309 ultimately drives the bolt to rotate, achieving the specific maintenance effect.

[0054] A method for using a highway maintenance and inspection drone includes the following steps:

[0055] When conducting patrol missions, the main body of the drone 1 operates through the output motor 103, which drives the blades 104 to rotate. In conjunction with the wing structure 102, it achieves the lifting and driving effect of the fuselage 101, and achieves the monitoring and visual detection functions in the patrol mission based on the operation of the depth camera 105.

[0056] During the takeoff and landing of the fuselage 101, the landing gear 108 contacts the ground. During landing, the landing gear 108 transmits vibration to the movable shaft 107, causing the movable shaft 107 to slide inside the hollow cylinder 106. At this time, based on the elastic force of the buffer spring 109 and the shock-absorbing spring 110, the vibration is buffered, thereby protecting the fuselage 101 and its assembly filling mechanism 2 or maintenance mechanism 3.

[0057] During the assembly of filling mechanism 2 or maintenance mechanism 3, the rotation trajectory of opening and closing plate 112 is limited by center frame 111, and the lifting frame 115 is driven by the operation of electric drive screw 114 in a threaded manner, so that the lifting frame 115 moves up and down. During the process, force is applied to opening and closing plate 112 by connecting shaft 116, which drives several sets of buckles 113 to move, so that buckles 113 are inserted into the positioning frame of first connecting plate 201 or second connecting plate 301, thereby achieving the automated assembly effect of filling mechanism 2 or maintenance mechanism 3.

[0058] When road filling or painting is required, the filling mechanism 2 is assembled, and the corresponding filler is filled into the hopper 202. The extension and retraction of the first electric telescopic rod 207 cooperates with the linkage frame 206 to make the pumping pump 205 rotate along the lower support frame 203. The output angle of the pumping pump 205 is adjusted, and the filler is pulled out by the operation of the pumping pump 205 and sent into the fusion chamber 209 through the feeding pipe 208. The fusion chamber 209 adjusts the air intake based on the air volume regulating valve 210. During the process of air entering the fusion chamber 209, air impurities are filtered by the air filter 211. The air and filler are mixed inside the fusion chamber 209, and the spraying work is carried out through the atomizing nozzle 212. Based on the properties of the filler, the functions of filling gaps or painting are realized.

[0059] Before assembling the maintenance mechanism 3, based on actual working needs, assemble an appropriate number of flipping mechanisms and adjusting arms. The outer guide rail 303 drives the bidirectional screw 304 to rotate, which in turn drives the two sets of drive frames 305 to move in opposite directions. This allows the drive shaft 306 to be placed inside the drive groove. The drive frame 305 then drives the drive shaft 306 to rotate, thereby controlling the flipping shaft 307 to flip. By assembling the corresponding number of flipping mechanisms and adjusting arms, the bending flexibility and counterweight of the maintenance mechanism 3 can be adjusted.

[0060] In the operation of maintenance mechanism 3, the drive frame 305 drives the rotating shaft 307 to rotate, and the second electric telescopic rod 308 extends and retracts to adjust the position of the clamping drive mechanism. The clamping drive mechanism drives the drive disk 312 to rotate through the operation of the secondary motor 310. During the rotation of the drive disk 312, multiple sets of linkage plates 315 are driven synchronously, thereby driving the slider 313 to move along the trajectory of the six-way guide rail 311, realizing the synchronous opening and closing function of multiple sets of clamping frames 314. The clamping frame 314 clamps the bolt, and the operation of the primary motor 309 ultimately drives the bolt to rotate, achieving the specific maintenance effect.

[0061] Working principle:

[0062] During patrol missions, the main body 1 of the drone operates through the output motor 103, driving the blades 104 to rotate. This, combined with the wing structure 102, achieves the lifting and driving effect on the fuselage 101. The depth camera 105 provides monitoring and visual inspection functions during the patrol mission. During takeoff and landing, the landing gear 108 contacts the ground. During landing, the landing gear 108 transmits vibrations to the movable shaft 107, causing it to slide inside the hollow cylinder 106. The spring force of the buffer spring 109 and the shock-absorbing spring 110 buffers the vibrations, thus protecting the fuselage 101 and its assembly / repair mechanism 2 or maintenance mechanism 3. During the process of constructing mechanism 3, the rotation trajectory of the opening and closing plate 112 is limited by the central frame 111, and the lifting frame 115 is driven by the operation of the electric drive screw 114 in a threaded manner, causing the lifting frame 115 to move up and down. During the process, the opening and closing plate 112 is subjected to force by the connecting shaft 116, which drives several sets of buckles 113 to move, so that the buckles 113 are inserted into the locking frame of the first connecting plate 201 or the second connecting plate 301, achieving the automated assembly effect of the filling mechanism 2 or the maintenance mechanism 3. When road filling or painting work is required, the filling mechanism 2 is assembled, and the corresponding filler is filled into the hopper 202. Through the extension and retraction of the first electric telescopic rod 207 and the linkage frame 206, the pumping pump 205 moves along the lower support. The support frame 203 rotates, adjusting the output angle of the pump 205. The pump 205 then dispenses the packing material, which is fed into the fusion chamber 209 via the feed pipe 208. The fusion chamber 209 adjusts the air intake using the air volume regulating valve 210. During air intake, the air filter 211 filters impurities. The air and packing material merge inside the fusion chamber 209, and the mixture is sprayed through the atomizing nozzle 212. Based on the packing material's properties, this process achieves filling of gaps or paint spraying. Before assembling the maintenance mechanism 3, an appropriate number of tilting mechanisms and adjusting arms are assembled based on actual working needs. The outer guide rail 303 drives the bidirectional screw 304 to rotate, which in turn drives the corresponding two sets of drive frames 305. This causes the two sets of drive frames 305 to move in opposite directions, thereby placing the drive shaft 306 into the drive groove. The drive frame 305 then rotates the drive shaft 306, which in turn controls the flipping shaft 307 to flip. Based on the assembly of the corresponding number of flipping mechanisms and adjusting arms, the bending flexibility and counterweight of the maintenance mechanism 3 can be adjusted. During the operation of the maintenance mechanism 3, the drive frame 305 rotates the flipping shaft 307, and the second electric telescopic rod 308 extends and retracts to adjust the position of the clamping drive mechanism. The clamping drive mechanism drives the drive disk 312 to rotate via the secondary motor 310. During the rotation of the drive disk 312, multiple sets of linkage plates 315 are driven synchronously, thereby causing the slider 313 to move along the flow guide rail trajectory.The system enables the synchronous opening and closing of multiple clamping frames 314. Each clamping frame 314 holds a bolt, and the operation of a primary motor 309 ultimately rotates the bolt, achieving the desired maintenance effect.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention.

8. A method of highway maintenance patrol drone device, characterized in that, Includes the following steps: When conducting patrol missions, the main body of the drone (1) operates through the output motor (103), which drives the blades (104) to rotate. In conjunction with the wing (102) structure, it achieves the lifting and driving effect on the fuselage (101), and achieves the monitoring and visual detection functions in the patrol mission based on the operation of the depth camera (105). During the takeoff and landing of the fuselage (101), the landing gear (108) contacts the ground. During landing, the landing gear (108) transmits vibration to the movable shaft (107), causing the movable shaft (107) to slide inside the hollow cylinder (106). At this time, based on the elastic force of the buffer spring (109) and the shock-absorbing spring (110), the vibration is buffered, thereby protecting the fuselage (101) and its assembly filling mechanism (2) or maintenance mechanism (3). During the assembly of the filling mechanism (2) or maintenance mechanism (3), the rotation trajectory of the opening and closing plate (112) is limited based on the central frame (111), and the lifting frame (115) is driven by the operation of the electric drive screw (114) in a threaded manner, so that the lifting frame (115) moves up and down. During the process, the opening and closing plate (112) is subjected to force based on the connecting shaft (116), which drives several sets of buckles (113) to move, so that the buckles (113) are inserted into the positioning frame of the first connecting plate (201) or the second connecting plate (301), thereby achieving the automated assembly effect of the filling mechanism (2) or maintenance mechanism (3). When road filling or painting is required, the filling mechanism (2) is assembled and the corresponding filler is filled into the hopper (202). The extension and retraction of the first electric telescopic rod (207) and the linkage frame (206) are coordinated to make the pump (205) rotate along the lower support frame (203). The output angle of the pump (205) is adjusted. The filler is pulled out by the operation of the pump (205) and sent into the fusion chamber (209) through the feeding pipe (208). The fusion chamber (209) adjusts the air intake based on the air volume regulating valve (210). During the process of air entering the fusion chamber (209), air impurities are filtered by the air filter (211). The air and the filler are fused in the fusion chamber (209). The spraying work is carried out through the atomizing nozzle (212). Based on the properties of the filler, the functions of filling gaps or painting are realized. Before assembling the maintenance mechanism (3), based on actual work needs, assemble an appropriate number of flipping mechanisms and adjusting arms. The outer guide rail (303) drives the bidirectional screw (304) to rotate, driving the corresponding two sets of drive frames (305) to move in opposite directions. Then, the drive shaft (306) is placed inside the drive groove, and the drive frame (305) drives the drive shaft (306) to rotate, thereby controlling the flipping shaft (307) to flip. Based on assembling the corresponding number of flipping mechanisms and adjusting arms, the bending flexibility and counterweight of the maintenance mechanism (3) can be adjusted. In the operation of the maintenance mechanism (3), the drive frame (305) drives the rotating shaft (307) to rotate, and the second electric telescopic rod (308) extends and retracts to adjust the position of the clamping drive mechanism. The clamping drive mechanism drives the drive disk (312) to rotate through the operation of the secondary motor (310). During the rotation of the drive disk (312), it drives multiple sets of linkage plates (315) synchronously, thereby driving the slider (313) to move along the trajectory of the six-way guide rail (311) to realize the synchronous opening and closing function of multiple sets of clamping frames (314). The clamping frame (314) clamps the bolt, and the bolt is finally driven to rotate based on the operation of the primary motor (309) to achieve the specific maintenance effect.
