[0017] Preferably, a method of using a modular road emergency repair device includes the following steps: S1. First, set up safety barriers and traffic control on the road surface to be repaired.

[0019] This invention provides a modular road emergency repair device. It has the following beneficial effects: 1. This invention, by setting up a DC motor to drive a bevel gear transmission, allows the auxiliary stirring rod and the main stirring rod to move in opposite directions, thereby achieving multi-angle stirring of aggregates. Furthermore, the piston block can be used to seal during the aggregate stirring process, thereby increasing the efficiency of aggregate stirring and making the aggregate more uniform during heating, thus solving the problem of low stirring efficiency in traditional repair devices.
[0020] 2. This invention, by setting an outer ring in conjunction with a ratchet pawl, allows the ratchet pawl to continuously push the push block during the mixing process, inserting the locking rod into the inside of the cover for physical locking. This effectively increases the safety of the device during aggregate mixing, effectively prevents heated aggregate from jumping out during mixing, and solves the problem of closure failure caused by factors such as power failure in traditional electronic locking.
[0021] 3. This invention uses a motor-driven screw transmission to enable the extrusion mechanism to move both horizontally and vertically. When these movements are coordinated, the aggregate can be extruded in a rectangular shape using the extrusion mechanism, thus achieving modular extrusion. This allows the repair device to easily fill the cut rectangular grooves, facilitating the modular road repair function. Attached Figure Description

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides a modular road emergency repair device, comprising a main body 1, a heating base 3 mounted on the top of the main body 1, an asphalt tank 6 fixedly connected to the top of the heating base 3, a hemispherical valve 13 mounted on the bottom of the asphalt tank 6, a slot 12 at the top of the asphalt tank 6, a cover 11 at the top of the asphalt tank 6, an external roller 14 rotatably connected inside the cover 11, an internal roller 15 rotatably connected inside the external roller 14, a motor frame 20 fixedly connected to the top connecting part of the cover 11, a handle 21 fixedly connected to one side of the motor frame 20, and a DC motor 41 mounted on the top of the motor frame 20. The output end is fixedly connected to a top bevel gear 23, the bottom of which is fixedly connected to the top of the built-in roller 15. The outside of the outer roller 14 is fixedly connected to a bottom bevel gear 24. An auxiliary bevel gear 22 is rotatably connected to the other side of the motor frame 20. One side of the auxiliary bevel gear 22 meshes with one side of the top bevel gear 23 and the bottom bevel gear 24. The outside of the built-in roller 15 is fixedly connected to a stirring rod 19. The bottom of the built-in roller 15 is fixedly connected to a piston block 40. The outside of the outer roller 14 is fixedly connected to an auxiliary frame 16. The outside of the auxiliary frame 16 is fixedly connected to a connecting rod 17. One side of the auxiliary frame 16 is fixedly connected to a stirring auxiliary rod 18.
[0026] Specifically, road repair aggregates and materials are fed into the asphalt tank 6, and then the cover 11 is inserted into the top of the asphalt tank 6. The aggregates and materials inside the asphalt tank 6 are then heated using the heating base 3. The DC motor 41 is then started to drive the top bevel gear 23 to rotate, and the bottom bevel gear 24 is driven in the opposite direction to the top bevel gear 23 by the auxiliary bevel gear 22. During this process, the outer roller 14 and the inner roller 15 rotate in opposite directions, which causes the mixing auxiliary rod 18 and the mixing main rod 19 to stir in opposite directions, thereby achieving the effect of fully mixing the aggregates and materials and making the heating of the aggregates and materials more uniform.
[0027] Please see the appendix Figure 6 and attached Figure 9 The cover 11 is internally fixedly connected to a locking body 25, and the locking body 25 is internally fixedly connected to a telescopic rod 37. One end of the telescopic rod 37 is fixedly connected to an inner slider 26. One side of the inner slider 26 is fixedly connected to a locking rod 27. The other side of the inner slider 26 is fixedly connected to a spring 38 through the inside of the locking body 25. One side of the inner slider 26 is fixedly connected to a push-out block 39. The push-out block 39 is slidably connected to one side of the locking body 25. The outer roller 14 is externally fixedly connected to an outer ring 35. The outer ring 35 is externally fixedly connected to a ratchet pawl 36.
[0028] Specifically, after the cover 11 is closed with the asphalt tank 6, during the stirring process of the DC motor 41, the outer roller 14 will rotate at high speed, synchronously driving the outer ring 35 and ratchet pawl 36 to rotate. The ratchet pawl 36 pushes the push block 39, which in turn drives the telescopic rod 37 to be inserted into the interior of the asphalt tank 6 for limiting. During this process, the telescopic rod 37 and the spring 38 are in a stretched state until the DC motor 41 stops running. Then, the telescopic rod 37 and the spring 38 can pull the locking rod 27 back to its original position, making it easy for the cover 11 to separate from the asphalt tank 6.
[0029] Please see the appendix Figure 1 , Figure 2 , Figure 7 and attached Figure 8The device body 1 has an oil cap 5 on its top, a push rod 4 fixedly connected to the top of the device body 1, a support frame 7 fixedly connected to the bottom of the device body 1, a moving mechanism 2 installed at the bottom of the support frame 7, moving wheels 10 fixedly connected to both ends of the moving mechanism 2, a fixed frame 9 fixedly connected to the bottom of the support frame 7, a first guide rod 8 fixedly connected inside the fixed frame 9, a first guide motor 28 installed inside the fixed frame 9, and a first adjusting screw 29 fixedly connected through the output end of the first guide motor 28 inside the fixed frame 9. The external thread of the first adjusting screw 29 is connected to... The sliding frame 30 is internally slidably connected to the outside of the first guide rod 8. The sliding frame 30 is internally fixedly connected to the second guide rod 31. A second guide motor 42 is installed on one side of the sliding frame 30. The output end of the second guide motor 42 passes through the inside of the sliding frame 30 and is fixedly connected to the second adjusting screw 32. The external thread of the second adjusting screw 32 is threadedly connected to the extrusion mechanism 33. One side of the extrusion mechanism 33 is slidably connected to the outside of the second guide rod 31. The output end of the extrusion mechanism 33 is connected to the hose 34. One end of the hose 34 is installed at the output end of the hemispherical valve 13.
[0030] Specifically, the hemispherical valve 13 can input the fully mixed and heated liquid into the extrusion mechanism 33 through the hose 34 and then extrude it. After the first guide motor 28 is started to rotate the first adjusting screw 29, the sliding frame 30 is moved laterally by the first guide rod 8. After the second guide motor 42 is started to rotate the second adjusting screw 32, the extrusion mechanism 33 is moved vertically by the second guide rod 31, so that the extrusion mechanism 33 can move along the rectangular structure, thereby further realizing the modular repair function.
[0031] A method for using a modular road emergency repair device includes the following steps: S1. First, set up safety barriers and traffic control on the road surface to be repaired. After determining the scope of the damage, use a cutting machine to cut along the marked line, and then use an electric pick or milling machine to thoroughly remove the damaged part. The cleaning depth is generally five to ten centimeters, forming a regular rectangular pit. After the cleaning is completed, use a high-pressure blower or broom to clean the debris inside the pit. S2. According to the original pavement gradation requirements, aggregates of different specifications are fed into the asphalt tank 6 according to the mix ratio. The petroleum asphalt is heated to 150 degrees Celsius and kept at a constant temperature. Then it is stirred for 30 seconds, and the discharge temperature is controlled between 140 degrees Celsius. S3. The well-mixed hot-mix asphalt mixture is extruded using the extrusion mechanism 33. The asphalt is evenly filled into the pothole in a rectangular modular extrusion method. The paving thickness should be slightly higher than the original road surface to avoid later settlement. A small double-drum roller or a hand-held plate vibratory compactor is used to compact the asphalt from the edge of the pothole towards the center. S4. After compaction, seal the joint between the repaired area and the original road surface. Apply a layer of hot asphalt or special road sealant along the joint. Alternatively, sprinkle a small amount of fine sand for sealing. After the road surface temperature naturally cools to below 50 degrees Celsius, remove excess material, check the flatness and compaction. Once the requirements are met, remove the barriers and open the road to traffic.
[0032] Working principle: Road repair aggregates and materials are fed into the asphalt tank 6. The cover 11 is then inserted into the top of the asphalt tank 6. The heating base 3 heats the aggregates and materials inside the asphalt tank 6. The DC motor 41 is then started to drive the top bevel gear 23 to rotate. The auxiliary bevel gear 22 drives the bottom bevel gear 24 in the opposite direction to the top bevel gear 23. During this process, the outer roller 14 and the inner roller 15 rotate in opposite directions, causing the mixing auxiliary rod 18 and the mixing main rod 19 to stir in opposite directions, achieving thorough mixing of the aggregates and materials and ensuring more uniform heating. After the cover 11 is closed to the asphalt tank 6, the outer roller 14 rotates at high speed during the stirring process of the DC motor 41, synchronously driving the outer ring 35 and the ratchet pawl 36. Rotation, using ratchet pawl 36 to push the ejector block 39, drives the telescopic rod 37 to be inserted into the asphalt tank 6 for limiting. During this process, the telescopic rod 37 and spring 38 are in a stretched state until the DC motor 41 stops running, which allows the telescopic rod 37 and spring 38 to pull the locking rod 27 back to its original position, facilitating the separation of the cover 11 from the asphalt tank 6. The hemispherical valve 13 can input the fully mixed and heated liquid into the extrusion mechanism 33 through the hose 34 for extrusion. After starting the first guide motor 28 to rotate the first adjusting screw 29, the sliding frame 30 is moved laterally using the first guide rod 8. After starting the second guide motor 42 to rotate the second adjusting screw 32, the extrusion mechanism 33 is moved vertically using the second guide rod 31, thereby allowing the extrusion mechanism 33 to move along the rectangular structure, further realizing the modular repair function.
[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
