Description

Technical Field

[0001] The present invention relates to the technical field of road surface repair, and particularly to a municipal road surface repair device. Background Art

[0002] The municipal road surface refers to the road surface for vehicles and pedestrians inside the city. Due to natural wear, natural disasters, aging of road surface materials, etc., problems will occur in the road surface condition. Road surface cracks are one of the common diseases of roads. Common road surface cracks include longitudinal cracks, transverse cracks, net cracks, etc. When the road surface is damaged, it needs to be repaired in time to restore its function.

[0003] In the current process of road surface repair, usually, workers first clean the damaged area with cracks, remove loose debris, gravel, dust, etc., to ensure the cleanliness of the base surface, and then use appropriate filling materials according to the type of damage to fill the damaged area for repair. For small longitudinal cracks and transverse cracks, a mobile caulking device is usually used to fill the damaged area with asphalt repair materials for repair. However, the overall portability of the mobile caulking device needs to be improved. For single repair situations, preparing a large amount of asphalt repair liquid will increase the maintenance cost. Secondly, for the asphalt repair materials in the mobile caulking device, long standing time may lead to precipitation and cooling, which is not conducive to the paving and leveling of the asphalt repair materials during repair. Moreover, when cleaning the damaged area manually, the efficiency needs to be improved, there is a situation of secondary pollution, and it is not convenient for workers to control the release amount of the asphalt repair liquid according to the damaged area, resulting in too much or too little release, which affects the filling effect.

[0004] Therefore, in order to improve the overall portability of the device and enhance the filling effect, the present invention provides a municipal road surface repair device. Summary of the Invention

[0033] Refer to Figures 1 to 2, A municipal road surface repair device, including a storage device 1 and a flow control device 8. The storage device 1 includes a heat preservation box body 11. On the left and right sides of the front side wall of the heat preservation box body 11, there are symmetrically fixed double shoulder straps 12. Inside the heat preservation box body 11, there are a stirring bin 13 and a discharging bin 14 arranged from left to right. On the top wall of the heat preservation box body 11, there is a feeding port 15 communicating with the stirring bin 13. On the lower right wall of the storage device 1, there is a blanking port 16 communicating with the discharging bin 14. A material guiding port is arranged between the stirring bin 13 and the discharging bin 14; an discharging device 2 is arranged on the storage device 1, and a moving support frame 5 is arranged outside the storage device 1. Quick release devices 3 are arranged on both the storage device 1 and the moving support frame 5. A heat preservation pipeline 4 is connected between the two quick release devices 3. In the middle of the top wall of the moving support frame 5, there is a telescopic control rod 6 hinged; a cleaning device 7 and a flow control device 8 are arranged on the moving support frame 5.

[0034] During use, carry the heat preservation box body 11 on the shoulder through the double shoulder straps 12, hold the grip and operate the telescopic control rod 6 to drive the moving support frame 5 to move on the municipal road surface to be repaired, locate the crack to be repaired and carry out the repair operation; supplement the asphalt repair liquid into the stirring bin 13 through the feeding port 15. A heating rod is arranged inside the heat preservation box body 11, and heat preservation layers are arranged on both the heat preservation box body 11 and the heat preservation pipeline 4 to prevent the asphalt repair liquid from cooling during use; through the discharging device 2, stir the asphalt repair liquid inside the stirring bin 13 and change the pressure inside the discharging bin 14, so that the asphalt repair liquid is discharged to the heat preservation pipeline 4 through the blanking port 16. The upper and lower ends of the heat preservation pipeline 4 are respectively connected to the storage device 1 and the moving support frame 5 through the quick release device 3, which is convenient for quick disassembly and maintenance; clean the crack to be repaired through the cleaning device 7, and adjust the flow rate of the released asphalt repair liquid according to the depth of the crack to be repaired through the flow control device 8.

[0035] Refer to Figures 2 to 3 , The discharging device 2 includes a stirring mechanism 21 for stirring the asphalt repair liquid inside the stirring bin 13. The stirring mechanism 21 includes a motor 1 211. The motor 1 211 is installed on the top wall of the heat preservation box body 11 through an inverted L-shaped plate. On the bottom wall of the output end of the motor 1 211, there is a rotating shaft 212 rotatably connected to the upper and lower inner walls of the stirring bin 13. On the side wall of the rotating shaft 212, there are a plurality of stirring rods 213 symmetrically distributed from top to bottom and left to right. The stirring rods 213 on the same side are jointly connected to a scraping plate 214, and the side wall of the scraping plate 214 is attached to the inner wall of the stirring bin 13.

[0036] Refer to Figures 2 to 3, a discharge driving mechanism 22 is provided on the stirring mechanism 21. The discharge driving mechanism 22 includes a threaded rod 221. The upper and lower inner walls of the discharge bin 14 are jointly rotatably connected with the threaded rod 221. The upper part of the side wall of the threaded rod 221 is coaxially connected with a first gear 222. The side wall of the rotating shaft 212 at the corresponding height is coaxially connected with a second gear 223. A toothed belt 224 is jointly meshed and connected to the side walls of the first gear 222 and the second gear 223.

[0037] Refer to Figures 2 to 3 , an opening and closing discharge mechanism 23 is provided on the discharge driving mechanism 22. The opening and closing discharge mechanism 23 includes a rubber plug 231. The side wall of the threaded rod 221 is threadedly connected with a rubber plug 231 that slides up and down on the inner wall of the discharge bin 14. The left side wall of the rubber plug 231 is fixedly connected with a first opening and closing plug 232 through a vertical rod. The first opening and closing plug 232 is composed of two plug bodies that slide up and down through a spring. A first rack 233 that slides up and down on the rear inner wall of the discharge bin 14 is fixed to the right side wall of the rubber plug 231. A third gear 234 rotatably connected to the rear inner wall of the discharge bin 14 is meshed with the right side wall of the first rack 233. A second rack 235 that slides up and down on the rear inner wall of the discharge bin 14 is meshed with the right side wall of the third gear 234. A second opening and closing plug 236 is fixedly connected to the right side wall of the second rack 235.

[0038] Refer to Figure 2 and Figure 4 , an adaptation component 24 is provided on the opening and closing discharge mechanism 23. The adaptation component 24 includes a first adjusting part 241. The front side wall of the upper plug body of the first opening and closing plug 232 is fixedly connected with the first adjusting part 241. A current-limiting baffle 244 is rotatably connected between the front and rear side walls of the discharge bin 14 through a torsion spring rod. A third adjusting part 243 is attached to the left front wall of the current-limiting baffle 244. The inclined rear side wall of the third adjusting part 243 is adapted to the chamfered front side wall of the current-limiting baffle 244. The front side wall of the third adjusting part 243 is connected to a vertical plate that slides back and forth through a spring (not shown in the figure) at the bottom of the discharge bin 14. A second adjusting part 242 is connected to the front side wall of the vertical plate. The bottom wall of the second adjusting part 242 and the top wall of the first adjusting part 241 are both inclined planes and are adapted to each other.

[0039] The first motor 211 is a forward and reverse motor. The output end of the first motor 211 drives the rotating shaft 212 to rotate. The rotating shaft 212 drives the stirring rod 213 and the scraping plate 214 to rotate. During the rotation of the stirring rod 213, the asphalt repair liquid inside the stirring bin 13 is stirred to prevent cooling and solidification, and at the same time, ensure the uniformity of the distribution and heating of the asphalt repair liquid in the stirring bin 13, making it easier to spread and level during repair.

[0040] While the first motor 211 rotates, it drives the second gear 223 to rotate. As a result, the toothed belt 224 drives the first gear 222 to rotate, and the first gear 222 drives the threaded rod 221 to rotate, causing the rubber plug 231 to slide on the inner wall of the discharge bin 14. When the rubber plug 231 moves upward, the first opening and closing plug 232 moves upward accordingly, causing the material guiding port opened between the mixing bin 13 and the discharge bin 14 to change from a closed state to an open state. The asphalt repair liquid inside the mixing bin 13 flows through the material guiding port into the discharge bin 14. At the same time, the rubber plug 231 drives the first rack 233 to move upward, and the third gear 234 rotates to drive the second rack 235 and the second opening and closing plug 236 to move downward, causing the blanking port 16 to change from an open state to a closed state. The right side wall of the heat preservation box body 11 is temporarily closed, and a negative pressure is formed inside the discharge bin 14, which is conducive to the smooth flow of the asphalt repair liquid into the discharge bin 14.

[0041] At the same time, when the first opening and closing plug 232 moves upward, the upper plug body drives the first adjusting part 241 to move upward first. The spring between the upper plug body and the lower plug body rebounds, and the lower plug body stays at the material guiding port between the mixing bin 13 and the discharge bin 14 for a period of time. The first adjusting part 241 moves upward and pushes the second adjusting part 242 to move backward. The vertical plate slides backward adaptively, driving the third adjusting part 243 to slide backward, and pushing the left end of the flow limiting baffle 244 to slide downward along the inclined bottom wall of the third adjusting part 243 to reduce the height. The torsion spring rod in the middle of the flow limiting baffle 244 rotates and deflects, causing the right end of the flow limiting baffle 244 to rise. The flow limiting baffle 244 with a lower left and a higher right partially blocks the blanking port 16, preventing a large amount of asphalt repair liquid from leaking out during the downward movement of the second opening and closing plug 236, and facilitating better control of the transfer of the asphalt repair liquid.

[0042] When the rubber plug 231 moves downward, the first opening and closing plug 232 moves downward, causing the material guiding port opened between the mixing bin 13 and the discharge bin 14 to change from an open state to a closed state, and the asphalt repair liquid gradually stops flowing through the material guiding port into the discharge bin 14. At the same time, the second opening and closing plug 236 moves upward, causing the blanking port 16 to change from a closed state to an open state, so as to discharge the asphalt repair liquid inside the discharge bin 14.

[0043] Refer to Figure 1 、 Figure 5 and Figure 6, the quick-release device 3 includes a connecting female part 31. The movable support frame 5 is composed of an X-shaped frame and universal wheels installed at the four corners of the bottom wall of the X-shaped frame. The rear top wall of the X-shaped frame of the movable support frame 5 and the blanking port 16 are both connected with the connecting female part 31. Adjusting grooves 32 are symmetrically opened on the side walls of the connecting female part 31. Limiting wedge blocks 34 are slidably connected inside the adjusting grooves 32. The limiting wedge blocks 34 are commonly connected with an adjusting ring 33 through springs. The adjusting ring 33 is rotatably connected to the side wall of the connecting female part 31 through a torsion spring (not shown in the figure). A connecting male part 35 is snap-fitted inside the connecting female part 31. The connecting male part 35 is composed of a hollow tube and blocks symmetrically distributed on the side wall of the hollow tube. The top walls of the limiting wedge blocks 34 and the bottom walls of the blocks of the connecting male part 35 are both inclined.

[0044] When disassembling and assembling the heat-insulating pipeline 4, the connecting male parts 35 connected to both ends of the heat-insulating pipeline 4 are inserted into the connecting female parts 31 on the corresponding storage device 1 and the movable support frame 5. When the connecting male part 35 enters the inside of the connecting female part 31, the blocks of the connecting male part 35 gradually approach the limiting wedge blocks 34 until the inclined side walls of the two fit together. The connecting male part 35 continues to move, and the springs connecting the limiting wedge blocks 34 and the adjusting ring 33 are adaptively compressed. The connecting male part 35 continues to move until the inclined surface of the block leaves the inclined surface of the limiting wedge block 34. At this time, the springs rebound, and the limiting wedge blocks 34 and the connecting female part 31 cooperate to limit the connecting male part 35. The blanking port 16, the heat-insulating pipeline 4, and the movable support frame 5 form a communicating state through the quick-release device 3, which is convenient for the asphalt repair liquid to be transferred to the crack to be repaired for repair work.

[0045] When disassembling the connecting female part 31 and the connecting male part 35, the adjusting ring 33 is rotated around the outer wall of the connecting female part 31, and the torsion spring connecting the connecting female part 31 and the adjusting ring 33 is adaptively stretched. The adjusting ring 33 drives the limiting wedge blocks 34 to rotate around to an intersecting position above the blocks of the connecting male part 35. At this time, the heat-insulating pipeline 4 and the connecting male part 35 can be pulled out to achieve quick disassembly. The adjusting ring 33 and the limiting wedge blocks 34 are reset by the driving of the torsion spring to return to their original positions. One insertion, one twist, and one pull achieve the quick installation and disassembly of the heat-insulating pipeline 4, improving the efficiency of maintenance and inspection.

[0046] Refer to Figure 1 And Figure 7 , the cleaning device 7 includes a triangular stabilizing plate 71. The front side wall of the movable support frame 5 is fixedly connected with a triangular stabilizing plate 71. A brushing mechanism 72 is arranged on the triangular stabilizing plate 71. The brushing mechanism 72 includes a second motor 721. The second motor 721 is installed on the top wall of the triangular stabilizing plate 71 through an inverted L-shaped plate. The bottom wall of the output end of the second motor 721 is fixedly connected with a fourth gear 722. A fifth gear 723 is meshed with the side wall of the fourth gear 722. Cleaning brushes 724 rotatably connected to the triangular stabilizing plate 71 are fixed to the bottom walls of the fourth gear 722 and the fifth gear 723.

[0047] Refer to Figures 7 to 8 , a purging mechanism 73 is provided on the triangular stabilizing plate 71. The purging mechanism 73 includes an air pump 731. The air pump 731 is installed on the top wall of the triangular stabilizing plate 71. The bottom wall of the output port of the air pump 731 is connected with a blowing head 732. The blowing head 732 is arranged at the rear side of the cleaning brush 724. The bottom wall of the moving support frame 5 is fixedly connected with a U-shaped dust-proof baffle 733 with an opening facing forward.

[0048] When the hand-held telescopic control rod 6 drives the moving support frame 5 to move on the ground to the crack to be repaired, the driving gear four 722 of the motor two 721 rotates, and then drives the gear five 723 to rotate, so that the cleaning brush 724 rotates to brush and clean at the crack to be repaired, removing dust and gravel; at the same time, the air pump 731 is started, and the fast air flow is blown out from the blowing head 732 to the cleaning area of the cleaning brush 724. The U-shaped dust-proof baffle 733 blocks the dust and gravel raised during cleaning, reducing the impact on the repair operation at the rear of the moving support frame 5. The cooperation of the blowing head 732 and the cleaning brush 724 improves the cleaning efficiency, ensures the cleanliness of the repair area, and keeps the repair area dry.

[0049] Refer to Figure 9 , an adjusting pipe 81 is fixedly penetrated through the rear bottom wall of the moving support frame 5. The top and the right side wall of the adjusting pipe 81 are respectively connected with a connecting female part 31 and an inverted L-shaped discharge pipe 82. The bottom wall of the inverted L-shaped discharge pipe 82 is fixed with a moving disc 83. The moving disc 83 is composed of a ring connected to the inverted L-shaped discharge pipe 82 and a plurality of balls distributed along the circumferential direction on the bottom wall of the ring.

[0050] Refer to Figures 9 to 10 , the flow control device 8 includes a control mechanism 84. The control mechanism 84 includes a chute 841. A plurality of chutes 841 are opened along the circumferential direction in the middle of the bottom wall of the moving support frame 5. A slide rod 842 is slidably connected up and down in each chute 841. The bottom walls of the slide rods 842 are jointly fixed with a reaction table 843. The reaction table 843 is composed of a disc connected to the slide rod 842 and a universal wheel installed on the bottom wall of the disc. A spring sleeved on the outer wall of the slide rod 842 is connected between the top wall of the reaction table 843 and the bottom wall of the moving support frame 5. A reaction rod 844 is fixed on the top wall of the reaction table 843. An adjusting rod 845 that is slidably connected up and down to the left side wall of the adjusting pipe 81 is clamped on the right side wall of the reaction rod 844. A conical control head 846 arranged inside the adjusting pipe 81 is fixed on the right side wall of the adjusting rod 845 through a rod. A control ring 847 is fixed on the inner wall of the adjusting pipe 81 and is arranged above the conical control head 846.

[0051] The universal wheels of the moving support frame 5 are always in contact with the ground around the crack. During the movement of the moving support frame 5, the universal wheels of the reaction platform 843 are always inside the crack to be repaired. The balls of the moving disc 83 are in contact with the ground, reducing the wear on the bottom end of the inverted L-shaped discharge pipe 82 and increasing the smoothness of the movement. The asphalt repair liquid flows through the heat preservation pipeline 4 into the regulating pipe 81, and after passing through the control ring 847, it flows into the crack to be repaired through the inverted L-shaped discharge pipe 82 for filling.

[0052] The reaction platform 843 changes in height according to the depth of the crack to be repaired. The sliding rod 842 slides up and down inside the sliding groove 841, and the spring sleeved on the outer wall of the sliding rod 842 expands and contracts adaptively with the up and down movement of the reaction platform 843. The height change of the reaction platform 843 drives the reaction rod 844 to move, driving the regulating rod 845 and the conical control head 846 to move up and down. When the depth of the crack to be repaired is relatively shallow, the reaction platform 843 drives the conical control head 846 to move up and approach the control ring 847, gradually reducing the cross-sectional area for the asphalt repair liquid to pass through in the middle of the control ring 847, and the flow rate of the asphalt repair liquid flowing out becomes smaller. On the contrary, when the depth of the crack to be repaired is relatively deep, the flow rate of the asphalt repair liquid flowing out becomes larger. If the bottom wall height of the universal wheel of the reaction platform 843 is the same as the bottom wall height of the universal wheel of the moving support frame 5, it means that the reaction platform 843 has moved out of the crack to be repaired at this time, and the conical control head 846 completely blocks the control ring 847, blocking the outflow of the asphalt repair liquid, so as to automatically adjust the flow rate according to the depth of the crack during the process of filling horizontal or vertical cracks, reducing the situation of excessive or insufficient release of the asphalt repair liquid and improving the accuracy of the repair.

[0053] Refer to Figures 1 - 10 As shown in the figure, the specific operation steps of this municipal road surface repair equipment are as follows: When in use, carry the heat preservation box body 11 on the shoulder through the double shoulder straps 12, hold the grip and operate the telescopic control rod 6 to drive the moving support frame 5 to move on the road surface to be repaired, locate the crack to be repaired and carry out the repair operation, supplement the asphalt repair liquid into the mixing bin 13 through the feed port 15, and the mixing rod 213 stirs the asphalt repair liquid inside the mixing bin 13 during rotation.

[0054] The asphalt repair liquid discharges from the discharge port 16 to the heat preservation pipeline 4. The limit wedge 34 and the connecting female part 31 cooperate to limit the connecting sub part 35, and the discharge port 16, the heat preservation pipeline 4 and the moving support frame 5 form a connected state through the quick-release device 3.

[0055] The cleaning brush 724 rotates to brush and clean the crack to be repaired. The fast air flow blows towards the crack to be repaired through the air blowing head 732. The U-shaped dust-proof baffle 733 blocks the dust and gravel raised by the cleaning, reducing the impact on the repair operation at the rear of the mobile support frame 5. The air blowing head 732 and the cleaning brush 724 cooperate to improve the cleaning efficiency. During the process of filling the horizontal or vertical cracks, the reaction table 843 drives the conical control head 846 to approach or move away from the control ring 847, and the flow rate can be self-adjusted according to the depth of the horizontal or vertical cracks.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
