[0002] Municipal road pavement refers to the road surface within the city for vehicles and pedestrians to pass. Due to natural wear and tear, natural disasters, aging of pavement materials and other reasons, problems may occur in the pavement condition. Pavement cracks are one of the common road diseases. Common pavement cracks include longitudinal cracks, transverse cracks, and network cracks. When the pavement is damaged, it needs to be repaired in time to restore its function.

[0003] In the current road repair process, the damaged area with cracks is usually cleaned manually first, loose debris, gravel and dust are removed to ensure the cleanliness of the base surface, and then appropriate filling materials are used to fill the damaged area for repair according to the type of damage. For small longitudinal and transverse cracks, mobile caulking equipment is usually used to fill asphalt repair materials into the damaged area for repair. However, the overall portability of mobile caulking equipment needs to be improved.

[0036] Reference Figures 2 to 3A discharging drive mechanism 22 is arranged on the stirring mechanism 21, and the discharging drive mechanism 22 includes a threaded rod 221. The upper and lower inner walls of the discharging bin 14 are rotatably connected with the threaded rod 221.

The side wall of the threaded rod 221 is threadedly connected with the rubber plug 231 that slides up and down on the inner wall of the discharging bin 14. The left side wall of the rubber plug 231 is fixedly connected with an opening and closing plug 232 through a vertical rod. The opening and closing plug 232 consists of two plug bodies connected by a spring that slides up and down. The right side wall of the rubber plug 231 is fixed with a rack 233 that slides up and down on the rear inner wall of the discharging bin 14.

[0038] Reference Figure 2 and Figure 4 , an adaption component 24 is provided on the opening and closing discharging mechanism 23, and the adaption component 24 includes an adjusting piece 1 241, and an adjusting piece 1 241 is fixed to the front side wall of the upper plug body of the opening and closing plug 1 232, and a limiting flow baffle 244 is rotatably connected between the front and rear side walls of the discharging bin 14 through a torsion spring rod, and an adjusting piece 3 243 is attached to the left front wall of the limiting flow baffle 244, and the inclined rear side wall of the adjusting piece 3 243 is adapted to the chamfered front side wall of the limiting flow baffle 244, and the front side wall of the adjusting piece 3 243 is connected to a vertical plate that is slidably connected to the bottom of the discharging bin 14 through a spring (not shown in the figure), and the front side wall of the vertical plate is connected to an adjusting piece 242, and the bottom wall of the adjusting piece 242 and the top wall of the adjusting piece 1 241 are both inclined and adapted.

[0039] Motor 1 211 is a forward and reverse motor. The output end of motor 1 211 drives the rotating shaft 212 to rotate, and the rotating shaft 212 drives the stirring rod 213 and the scraper 214 to rotate. The stirring rod 213 stirs the asphalt repair liquid inside the mixing chamber 13 during the rotation to prevent cooling and solidification, while ensuring the distribution and heating uniformity of the asphalt repair liquid in the mixing chamber 13, making it easier to spread and level during repair.

[0040] When the motor 211 rotates, it drives the gear 223 to rotate, and then the toothed belt 224 drives the gear 1 222 to rotate, and the gear 1 222 drives the threaded rod 221 to rotate, so that the rubber plug 231 slides on the inner wall of the discharge bin 14; when the rubber plug 231 moves up, the opening and closing plug 1 232 moves up accordingly, so that the guide port opened between the mixing bin 13 and the discharge bin 14 changes from a closed state to an open state, and the asphalt repair liquid inside the mixing bin 13 flows into the discharge bin 14 through the guide port. At the same time, the rubber plug 231 drives the rack 1 233 to move up, and the gear 3 234 rotates to drive the rack 2 235 and the opening and closing plug 2 236 to move down, so that the discharge port 16 changes from an open state to a closed state, and the right side wall of the insulation box 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 opening and closing plug 232 moves upward, the upper plug body first drives the adjusting member 241 to move upward, the spring between the upper plug body and the lower plug body rebounds, and the lower plug body continues to stay at the guide port between the mixing bin 13 and the discharge bin 14 for a period of time, and the adjusting member 241 moves upward and pushes the adjusting member 242 to move backward, and the vertical plate adaptively slides backward, driving the adjusting member 3 243 to slide backward, pushing the left end of the flow limiting baffle 244 to slide along the inclined bottom wall of the adjusting member 3 243 to lower the height, and the torsion spring rod in the middle of the flow limiting baffle 244 rotates and deflects, so that the right end of the flow limiting baffle 244 is raised, and the discharge port 16 is partially blocked by the flow limiting baffle 244 with the lower left and the higher right, so as to prevent the asphalt repair fluid from leaking out in large quantities during the descent of the opening and closing plug 236, so as to better control the transfer of the asphalt repair fluid.

[0042] When the rubber plug 231 moves downward, the opening and closing plug 232 moves downward, causing the material guide 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 fluid gradually stops flowing through the material guide port to the inside of the discharge bin 14. At the same time, the opening and closing plug 236 moves upward, causing the discharge port 16 to change from a closed state to an open state, so as to discharge the asphalt repair fluid inside the discharge bin 14.

[0043] Reference Figure 1 , Figure 5 and Figure 6The quick-release device 3 includes a connecting mother component 31, and the mobile 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 inside of the connecting mother component 31 is engaged and connected with a connecting sub-component 35, and the connecting sub-component 35 is composed of a hollow tube and blocks symmetrically distributed on the side walls of the hollow tube. The top wall of the limit wedge 34 and the bottom wall of the block of the connecting sub-component 35 are both inclined.

[0044] When disassembling and assembling the insulated pipe 4, the connecting sub-components 35 connected at both ends of the insulated pipe 4 are inserted into the corresponding storage device 1 and the connecting mother component 31 on the movable support frame 5. When the connecting sub-component 35 enters the connecting mother component 31, the stopper of the connecting sub-component 35 gradually approaches the limiting wedge block 34 until the inclined side walls of the two are in contact with each other, and the connecting sub-component 35 continues to move, and the spring connected between the limiting wedge block 34 and the adjusting ring 33 is adaptively compressed. The connecting sub-component 35 continues to move until the inclined surface of the stopper leaves the inclined surface of the limiting wedge block 34. At this time, the spring rebounds, and the limiting wedge block 34 and the connecting mother component 31 cooperate to limit the connecting sub-component 35. The discharge port 16, the insulated pipe 4 and the movable support frame 5 are connected through the quick-release device 3, which is convenient for the asphalt repair liquid to be transferred to the crack to be repaired for repairing operations.

[0045] When disassembling the connecting mother component 31 and the connecting sub-component 35, the adjusting ring 33 is rotated around the outer wall of the connecting mother component 31, and the torsion spring connected between the connecting mother component 31 and the adjusting ring 33 is adaptively stretched. The adjusting ring 33 drives the limiting wedge block 34 to rotate to an intersecting position above the stop block of the connecting sub-component 35. At this time, the thermal insulation pipe 4 and the connecting sub-component 35 can be pulled out to achieve quick disassembly. The adjusting ring 33 and the limiting wedge block 34 are reset by the torsion spring reset drive. The thermal insulation pipe 4 can be quickly installed and disassembled by inserting, twisting and pulling, thereby improving the efficiency of maintenance and inspection.

[0048] When the handheld telescopic control rod 6 drives the mobile support frame 5 to move on the ground to the crack to be repaired, the drive 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 the crack to be repaired to remove dust and gravel; at the same time, the air pump 731 is started, and a fast airflow is blown out through the blowing head 732 to the cleaning area of ​​the cleaning brush 724, and the U-shaped dust baffle 733 blocks the dust and gravel raised during cleaning, thereby reducing the impact on the repair work at the rear of the mobile support frame 5.

An adjusting rod 845 slidably connected to the left side wall of the regulating tube 81 is engaged with the right side wall of the reaction rod 844. A conical control head 846 arranged inside the regulating tube 81 is fixed to the right side wall of the regulating rod 845 through the rod. A control ring 847 arranged above the conical control head 846 is fixed to the inner wall of the regulating tube 81.

[0051] The universal wheels of the mobile support frame 5 are always in contact with the ground around the crack. During the movement of the mobile support frame 5, the universal wheels of the reaction table 843 are always in the crack to be repaired. The ball of the mobile disk 83 is in contact with the ground, which reduces the wear on the bottom end of the inverted L-shaped discharge pipe 82 and increases the smoothness of movement. The asphalt repair liquid flows through the insulation pipe 4 to the regulating pipe 81, passes through the control ring 847, and then flows along the inverted L-shaped discharge pipe 82 to the crack to be repaired for filling.

[0052] The reaction table 843 changes in height as the depth of the crack to be repaired varies. The slide bar 842 slides up and down inside the slide groove 841. The spring sleeved on the outer wall of the slide bar 842 adaptively expands and contracts as the reaction table 843 moves up and down. The height change of the reaction table 843 drives the reaction rod 844 to move, driving the adjustment rod 845 and the conical control head 846 to move up and down. When the depth of the crack to be repaired is shallow, the reaction table 843 drives the conical control head 846 to move up and close to the control ring 847, gradually reducing the cross-sectional area of ​​the middle of the control ring 847 for the asphalt repair liquid to pass through , the flow rate of the asphalt repair liquid outflow becomes smaller, on the contrary, when the depth of the crack to be repaired is deeper, the flow rate of the asphalt repair liquid outflow becomes larger; if the bottom wall height of the universal wheel of the reaction table 843 is consistent with the bottom wall height of the universal wheel of the movable support frame 5, it means that the reaction table 843 is moved out of the crack to be repaired at this time, and the conical control head 846 completely blocks the control ring 847 to prevent the outflow of the asphalt repair liquid, so as to self-regulate the release flow according to the depth of the crack in the process of filling the horizontal or vertical cracks, reduce the situation of excessive or insufficient release of asphalt repair liquid, and improve the accuracy of the repair.

[0053] Reference Figure 1-Figure 10 The specific operation steps of the municipal road pavement repairing equipment are as follows: when in use, the insulation box 11 is carried on the shoulders through the shoulder straps 12, the telescopic control rod 6 is operated by holding the handle, the mobile support frame 5 is driven to move on the road surface to be repaired, the crack to be repaired is located for repairing, and the asphalt repair liquid is added into the mixing chamber 13 through the feed port 15. The stirring rod 213 stirs the asphalt repair liquid inside the mixing chamber 13 during the rotation process.

[0054] The asphalt repair liquid is discharged to the insulation pipe 4 through the discharge port 16 , the limiting wedge block 34 and the connecting mother component 31 cooperate to limit the connecting subcomponent 35 , and the discharge port 16 , the insulation pipe 4 and the movable support frame 5 are connected through the quick release device 3 .

[0055] The cleaning brush 724 rotates to brush and clean the cracks to be repaired, and a fast airflow is blown toward the cracks to be repaired through the air blowing head 732. The U-shaped dust baffle 733 blocks the dust and gravel raised by cleaning, thereby reducing the impact on the repair work 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. In 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 release flow can be self-adjusted according to the depth of the horizontal or vertical cracks.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
