Description

Technical Field

[0001] This utility model relates to the field of highway crack sealing technology, and in particular to a highway crack sealing device. Background Technology

[0002] Crack sealant is a polymer-based road maintenance material specifically designed for repairing road surface cracks. It uses modified asphalt as a base, with added rubber powder, SBS, and various performance-enhancing additives, and is produced through a special gel-solidification process. It is solid at room temperature but melts into a liquid upon heating. With strong adhesion and high elasticity, it penetrates deep into the crack, completely encapsulating it and providing a secure and durable repair, preventing the crack from spreading. Using crack sealant for preventative maintenance can extend the road's lifespan and reduce maintenance costs. It is suitable for initial sealing of newly constructed roads and for the repair and maintenance of older roads. Crack sealant machines are typically used to repair road surface cracks.

[0003] Among them, diesel burners are the most common heat source in the heating system of crack sealing machines. They generate heat by burning diesel fuel to heat the crack sealing adhesive. Diesel burners have high power and stability and are suitable for large-scale crack sealing operations. Crack sealing equipment consists of a grooving machine, blower, brush, scraper, crack sealing equipment, and adhesive dispensing pipe. When using general crack sealing equipment, a transport vehicle is required. Moreover, the adhesive dispensing pipe and other parts are very bulky. Workers need to hold the adhesive dispensing pipe and aim it at the road surface cracks, which increases the burden and workload of maintenance workers, reduces the effectiveness of road surface crack repair, and cannot meet the actual needs. Utility Model Content

[0004] This utility model discloses a road crack sealing device, which aims to solve the technical problem that general crack sealing devices require a transport vehicle for use, and the parts such as the dispensing hose are very heavy. Workers need to hold the dispensing hose and aim it at the road cracks, which increases the burden and workload of maintenance workers and reduces the effectiveness of road surface crack repair.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A road crack sealing device includes a housing. A rotating frame is rotatably connected to the upper surface of the housing. A rubber sleeve is fixedly connected to the top of the rotating frame. A switch is fixedly connected to the upper surface of the housing near the rotating frame. Two fixing plates are fixedly connected to the lower surface of the housing near the rotating frame. A bogie is rotatably connected to one side of the bottom of the fixing plates. A rear wheel is rotatably connected to one end of the bogie. A linkage plate is rotatably connected to the other end of the bogie. A groove is provided on the upper surface of the middle position of the linkage plate. A crack sealing glue tank is fixedly connected inside the housing. A heating tube is provided inside the crack sealing glue tank. A battery is fixedly connected to the inside of the housing near the crack sealing glue tank. A rotating shaft is rotatably connected to the bottom of the housing. Front wheels are fixedly connected to both ends of the rotating shaft. A discharge pipe is inserted into the bottom of the crack sealing glue tank.

[0007] The switch, heating element, and battery are electrically connected. The bottom end of the rotating frame slides inside the groove. A heat insulation plate is provided between the grout box and the battery to protect the battery.

[0008] One end of the rotating frame penetrates the outer shell, and openings are provided at the positions where the rotating frame penetrates the outer shell, so that the rotation of the rotating frame does not interfere with the outer shell.

[0009] An insulation sleeve is fixedly connected to one side of the outer wall of the outer shell near the discharge pipe. A fixing rod is fixedly connected to one side of the outer wall of the outer shell near the insulation sleeve. A sealing plate is rotatably connected to the bottom end of the fixing rod. A stop block is fixedly connected to the upper surface of the sealing plate. A sealing frame is fixedly connected to one end of the sealing plate.

[0010] In a preferred embodiment, a combustion chamber is fixedly connected to the bottom of the grouting box inside the outer shell, an isolation plate is provided at the bottom of the combustion chamber, and an ash chamber is provided at the bottom of the isolation plate.

[0011] The top of the outer casing is rotatably connected to a second sealing plate directly above the grouting box. A first handle is fixedly connected to the upper surface of the second sealing plate. The first sealing plate is rotatably connected to one side of the outer casing near the combustion chamber. A second handle is fixedly connected to one side of the first sealing plate.

[0012] Multiple air inlets are provided on both sides of the outer casing near the front wheels. An exhaust pipe is inserted into the top of the combustion chamber. The exhaust pipe passes through the sealant box and the outer casing, with one end of the exhaust pipe extending from the top of the outer casing.

[0013] As can be seen from the above, the road crack sealing device provided by this utility model has the following technical effects.

[0014] Firstly, by manually pulling the rotating frame while the maintenance worker moves backward, the outer casing moves forward. By observing the position of the bottom of the insulation sleeve, the crack sealant is placed on the crack in the road surface. Since the cracks on the road are not straight, by manually rotating the rotating frame, the bottom of the frame drives the linkage plate to swing left and right, causing the two bogies to drive the rear wheels to rotate, thereby changing the direction of movement of the outer casing. This ensures that the bottom of the insulation sleeve is always directly above the crack in the ground. By placing the crack sealant inside the outer casing, which also has the function of heating the sealant, the maintenance worker does not need to use handheld equipment to repair the cracks in the ground, thus reducing the burden on maintenance workers in repairing ground cracks.

[0015] Secondly, when the battery is depleted, the first sealing plate can be opened, and combustible materials can be placed inside the combustion chamber and ignited. The combustion of the combustible materials heats the bottom of the crack sealant box, melting the crack sealant inside. Combustible materials include wood or coal, etc. Fresh air enters the combustion chamber through the air inlet to provide oxygen for the combustion of the combustible materials. The smoke generated by the combustion is discharged through the exhaust pipe, which can achieve the effect of repairing road cracks when there is no power. Attached Figure Description

[0023] The highway crack sealing equipment disclosed in this utility model mainly applies to general crack sealing equipment. When used, it requires a transport vehicle, and the parts such as the dispensing hose are very heavy. Workers need to hold the dispensing hose and aim it at the road surface cracks, which increases the burden and workload of maintenance workers and reduces the effectiveness of highway surface crack repair.

[0024] Reference Figure 1 — Figure 4 A road crack sealing device includes a housing 1. A rotating frame 6 is rotatably connected to the upper surface of the housing 1. A rubber sleeve is fixedly connected to the top of the rotating frame 6. A switch 11 is fixedly connected to the upper surface of the housing 1 near the rotating frame 6. Two fixing plates 10 are fixedly connected to the lower surface of the housing 1 near the rotating frame 6. A bogie 25 is rotatably connected to one side of the bottom of the fixing plate 10. A rear wheel 5 is rotatably connected to one end of the bogie 25. A linkage plate 24 is rotatably connected to the other end of the bogie 25. A groove 23 is provided on the upper surface of the middle position of the linkage plate 24. A crack sealing glue tank 14 is fixedly connected inside the housing 1. A heating tube 12 is provided inside the crack sealing glue tank 14. A battery 20 is fixedly connected to the inside of the housing 1 near the crack sealing glue tank 14. A rotating shaft is rotatably connected to the bottom of the housing 1. Front wheels 4 are fixedly connected to both ends of the rotating shaft. A discharge pipe 18 is inserted into the bottom of the crack sealing glue tank 14.

[0025] The switch 11, heating tube 12 and battery 20 are electrically connected. The bottom end of the rotating frame 6 slides inside the slide groove 23. A heat insulation plate is provided between the grouting box 14 and the battery 20 to protect the battery 20.

[0026] It should be noted that an inverter is installed on the battery 20, and the voltage of the battery 20 is boosted by the inverter and electrically connected to the heating tube 12.

[0027] One end of the rotating frame 6 passes through the outer shell 1, and openings are provided at the positions where the rotating frame 6 passes through the outer shell 1. The rotation of the rotating frame 6 does not interfere with the outer shell 1.

[0028] An insulation sleeve 8 is fixedly connected to one side of the outer wall of the outer casing 1 near the discharge pipe 18. A fixing rod 19 is fixedly connected to one side of the outer wall of the outer casing 1 near the insulation sleeve 8. A sealing plate 21 is rotatably connected to the bottom end of the fixing rod 19. A stop block 22 is fixedly connected to the upper surface of the sealing plate 21. A sealing frame 9 is fixedly connected to one end of the sealing plate 21.

[0029] In this embodiment, the sealant is placed inside the sealant tank 14. At this time, the sealant is in a solid state. By turning on the switch 11, the circuit between the battery 20 and the heating tube 12 is connected. Current flows through the heating tube 12, causing it to heat up and thus heating the sealant inside the sealant tank 14, melting it into a liquid state. The liquid sealant flows out through the discharge pipe 18. The maintenance worker manually pulls the rotating frame 6 while simultaneously moving backward, causing the outer casing 1 to move forward. By observing the bottom position of the insulation sleeve 8, the sealant is... When the crack in the road surface is not straight, the rotating frame 6 is turned by hand. The bottom of the rotating frame 6 drives the linkage plate 24 to swing left and right, so that the two bogies 25 drive the rear wheel 5 to rotate, thereby changing the direction of movement of the outer shell 1. This ensures that the bottom of the insulation sleeve 8 is always directly above the crack in the ground. By placing the crack filler inside the outer shell 1, the interior of the outer shell 1 also has the function of heating the crack filler. This eliminates the need for maintenance workers to use handheld equipment to repair the crack in the ground, thus reducing the burden on maintenance workers in repairing ground cracks.

[0030] Furthermore, after the repair is completed, the maintenance worker can rotate one end of the sealing frame 9 with his foot, causing the sealing frame 9 to drive the sealing plate 21 to rotate, so that the sealing plate 21 blocks the bottom of the insulation sleeve 8, stopping the flow of the sealant inside the insulation sleeve 8. The stop block 22 can ensure that the sealing plate 21 stops at the bottom of the insulation sleeve 8, thus saving sealant.

[0031] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a combustion chamber 15 is fixedly connected to the bottom of the grouting box 14 inside the outer shell 1. An isolation plate 16 is provided at the bottom of the combustion chamber 15, and an ash chamber 17 is provided at the bottom of the isolation plate 16.

[0032] The top of the outer casing 1 is rotatably connected to the second sealing plate 7 directly above the grouting box 14. The upper surface of the second sealing plate 7 is fixedly connected to the first handle. The first sealing plate 2 is rotatably connected to one side of the outer casing 1 near the combustion chamber 15. The first sealing plate 2 is fixedly connected to one side of the first sealing plate 2.

[0033] Multiple air inlets 3 are provided on both sides of the outer casing 1 near the front wheel 4. An exhaust pipe 13 is inserted into the top of the combustion chamber 15. The exhaust pipe 13 passes through the sealant box 14 and the outer casing 1, and one end of the exhaust pipe 13 extends out from the top of the outer casing 1.

[0034] In this embodiment, when the battery 20 runs out of power, the first sealing plate 2 can be opened, and combustible material can be placed inside the combustion chamber 15 and ignited. The combustion of the combustible material heats the bottom of the crack sealant box 14, causing the crack sealant inside the crack sealant box 14 to melt. The combustible material includes wood or coal, etc. Fresh air enters the combustion chamber 15 through the air inlet 3 to provide oxygen for the combustion of the combustible material. The smoke generated by the combustion is discharged through the exhaust pipe 13, which achieves the effect of repairing road cracks when there is no power.

[0035] Working principle: In use, the second sealing plate 7 is rotated to put the crack filler into the crack filler box 14. At this time, the crack filler is in a solid state. By turning on the switch 11, the circuit between the battery 20 and the heating tube 12 is connected. The current passes through the heating tube 12, causing it to heat up, thereby heating the crack filler inside the crack filler box 14 and melting it into a liquid state. The liquid crack filler flows out through the discharge pipe 18. The maintenance worker pulls the rotating frame 6 by hand, and at the same time, the maintenance worker moves backward, causing the outer shell 1 to move forward. By observing the position of the bottom end of the insulation sleeve 8, the crack filler is placed on the crack in the road surface. Since the crack in the road is not straight, by rotating the rotating frame 6 by hand, the bottom end of the rotating frame 6 drives the linkage plate 24 to swing left and right, causing the two steering frames 25 to drive the rear wheel 5 to rotate, thereby changing the direction of movement of the outer shell 1, so that the bottom end of the insulation sleeve 8 is always directly above the crack in the ground. By placing the crack filler inside the outer shell 1, the inside of the outer shell 1 also has a heating function. The function of the hot-applied crack sealant eliminates the need for maintenance workers to use handheld equipment to repair ground cracks, thus reducing their workload. When the battery 20 runs out of power, the first sealing plate 2 can be opened, and combustible materials can be placed inside the combustion chamber 15 and ignited. The combustion of the combustible materials heats the bottom of the crack sealant tank 14, melting the sealant inside. Combustible materials include wood or coal. Fresh air enters the combustion chamber 15 through the air inlet 3, providing oxygen for the combustion of the combustible materials. The smoke generated by the combustion is discharged through the exhaust pipe 13, enabling road crack repair even without power. After the repair is completed, the maintenance worker can rotate one end of the sealing frame 9 with their foot, causing the sealing frame 9 to rotate the sealing plate 21, which blocks the bottom of the insulation sleeve 8, stopping the sealant from flowing out. The stop block 22 ensures that the sealing plate 21 stops at the bottom of the insulation sleeve 8, thus saving sealant.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
