Description

Technical Field

[0001] The invention relates to the field of highway construction, in particular to crack repairing equipment used in highway construction. Background Art

[0002] Crack repair is a crucial and frequent task in highway construction. With the continued growth of traffic volume and the impact of natural environmental factors, various cracks in highway pavements are inevitable. These cracks not only affect the road's aesthetics but also pose a serious threat to its structural integrity and driving safety.

[0003] Currently, traditional highway crack repair technologies face numerous practical challenges. Existing methods often struggle to completely remove dust from cracks, especially at the crack ends, a critical area where dust and sand are most likely to accumulate. Common cleaning equipment and processes are unable to accurately and efficiently clean this area, resulting in residual dust that significantly impairs the adhesion of subsequent repair materials to the crack substrate, making repaired cracks susceptible to re-cracking.

[0004] When it comes to filling repair materials, existing technologies mostly use a continuous discharge method, which makes it difficult for construction workers to accurately control the discharge location and amount. On the one hand, material waste is likely to occur in some fine cracks that require a small amount of repair material; on the other hand, for long or complex cracks, it is difficult to accurately distribute materials in different locations according to actual needs, affecting the quality of the repair. Moreover, after the material is filled, traditional processes lack effective means of dispersing the material and usually rely on simple manual leveling. This is not only inefficient, but also difficult to ensure uniform material distribution, which brings great inconvenience to the subsequent compaction work, thus affecting the compaction and flatness of the entire repair project.

[0005] In summary, it is urgent to develop a road crack repair technology that is simple in structure, easy to use, and can effectively solve the crack cleaning problem, accurately control the discharge of materials, and efficiently disperse materials. To this end, those skilled in the art have proposed a crack repair device for road construction to address the problems raised in the above background. Summary of the Invention

[0025] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Example 1: Please refer to Figure 1 and Figure 4 A crack repair device for highway construction includes a movable base plate 1 and a movable box 2 fixedly connected to the movable base plate 1. A mounting bracket 3 is fixedly connected to the side of the movable base plate 1. A motor 4 is fixedly connected to the movable base plate 1. A cleaning hood 5 is fixedly connected to the mounting bracket 3. A cleaning wheel 6 is rotatably connected to the interior of the cleaning hood 5. The axle of the cleaning wheel 6 is in transmission connection with the rotor of the motor 4. A reciprocating dust hood 7 is provided on the side of the cleaning hood 5. The dust hood 7 is driven by the motor 4. The dust hood 7 moves along a guide plate 8 fixedly provided on the side of the cleaning hood 5. The height of the guide plate 8 is lower than the middle. When the dust hood 7 moves to the two ends, it moves downward and closer to the road surface. A driven pulley 9 is fixedly connected to the axle of the cleaning wheel 6. A driving pulley 10 is fixedly connected to the rotor of the motor 4. A transmission belt 11 is sleeved between the driving pulley 10 and the driven pulley 9.

[0028] When in use, the device is debugged and pushed to the position of an asphalt truck or concrete mixer. Asphalt or concrete is poured into the interior of the mobile box 2. Then, the motor 4 is turned on and the device is pushed to the position where the gap needs to be repaired. The motor 4 rotates to drive the cleaning wheel 6 to rotate. As the cleaning wheel 6 rotates, the outer cleaning brush sweeps the dust in the crack. The rotation direction of the motor 4 is controlled so that the cleaning brush cleans the dust in a single direction to the outside. At the same time, the motor 4 drives the dust hood 7 to move back and forth. When the dust hood 7 moves to the end position, it moves downward due to the surface movement of the guide plate 8, so that the dust hood 7 can suck up dust at a close distance. The edge of the ground gap is more likely to accumulate dust, and this structure can better clean the gap. When the motor 4 rotates, it drives the driving pulley 10 to rotate. The driving pulley 10 drives the transmission belt 11 to rotate. The rotation of the transmission belt 11 drives the driven pulley 9 to rotate, and then drives the cleaning wheel 6 to rotate for cleaning.

[0029] See also Figure 2 and Figure 5 , the movable base plate 1 is slidably connected to a ring member 12, and transmission teeth 13 are evenly distributed on the upper and lower sides of the inner side of the ring member 12. An incomplete gear 14 is fixedly connected to the outer side of the rotor of the motor 4, and the incomplete gear 14 alternately meshes with the upper and lower transmission teeth 13. A driving rack 15 is fixedly connected to the side of the ring member 12, and a guide beam 16 is fixedly connected to the mounting bracket 3. Two sliders 17 are slidably connected below the guide beam 16. The sliders 17 are all threadedly connected to the driving threaded shaft 18. The outer threads of the driving threaded shaft 18 are symmetrically arranged. The end of the threaded shaft 18 is fixedly connected to a driven gear 19, which meshes with the drive rack 15. A transmission rod 20 is rotatably connected to the bottom of the slider 17, and a driving block 21 is rotatably connected to the bottom of the transmission rod 20. The dust cover 7 is fixedly connected to the driving block 21, and the bottom of the driving block 21 is against the guide plate 8. When the driving block 21 cooperates with both ends of the guide plate 8, the transmission rod 20 is in a vertical state under the action of the torsion spring. When the slider 17 slides inward to the middle position of the driving block 21 and cooperates with the guide plate 8, the transmission rod 20 is in an inclined state.

[0030] The incomplete gear 14 rotates continuously and drives the annular member 12 to move back and forth. The annular member 12 further drives the drive rack 15 to move back and forth. The drive rack 15 drives the driven gear 19 to rotate and then drives the drive threaded shaft 18 to rotate back and forth. The drive threaded shaft 18 drives the slider 17 to move back and forth and simultaneously drives the dust hood 7 to move. The dust hood 7 is a prior art that provides a strong negative pressure through a motor to achieve dust collection. Its structure is similar to that of a vacuum cleaner. The dust hood 7 is connected to the slider 17 through a transmission rod 20. During the movement of the slider 17, the spring force of the torsion spring always contacts the upper surface of the guide plate 8. The dust hood 7 moves to the middle position to fully remove dust. The cleaning wheel 6 here has a better cleaning effect. However, at the corner position, the cleaning wheel 6 has a poor cleaning effect, so the dust hood 7 is used to supplement the cleaning to ensure the cleaning effect.

[0031] Example 2: This example further discloses a specific implementation of the discharging process based on the previous example: Please refer to Figure 1 and Figure 3 A discharge pipe 22 is fixedly connected to the side of the mobile housing 2. A discharge shaft 23 is rotatably connected to the inside of the discharge pipe 22. An auger 24 is fixedly connected to the outside of the discharge shaft 23. An end cap 25 is slidably connected to the outside of the discharge shaft 23. The end cap 25 cooperates with the end of the discharge pipe 22 to control the discharge. A driven bevel gear 26 is fixedly connected to the end of the discharge shaft 23. Two active bevel gears 27 are symmetrically fixedly connected to the outside of the drive threaded shaft 18. The active bevel gears 27 alternately mesh with the driven bevel gears 26. The end cap 25 is snap-fitted or threadedly engaged with the end of the discharge pipe 22. A mounting sleeve 28 is fixedly connected to the outside of the discharge shaft 23. Several scrapers 29 are connected to the mounting sleeve 28. The material discharged from the discharge pipe 22 is dispersed under the action of the scrapers 29. The outer side of the discharge shaft 23 is connected to multiple scrapers 29 through a mounting sleeve 28. The scrapers 29 can scrape the discharged concrete flat during the reciprocating rotation. The size of the scrapers 29 can be set as needed to achieve the best scraping effect.

[0032] Open the end cap 25, and the concrete or asphalt will be discharged through the discharge pipe 22. The two driving bevel gears 27 will alternately drive the driven bevel gear 26 to mesh, causing the discharge shaft 23 to reciprocate and discharge the material. The reciprocating rotation of the discharge shaft 23 causes the concrete or asphalt to be discharged outward in large quantities periodically. When the spiral auger 24 transports the concrete inward, only a small amount of concrete will flow out of the gap. Therefore, during the gap between the discharge of concrete or asphalt, the device can be moved to the location where a large amount of concrete is needed, facilitating a more even laying of the concrete and asphalt at different positions in the gap. Two symmetrical driving bevel gears 27 are arranged and alternately mesh with the driven bevel gear 26 to achieve the reciprocating motion of the driven bevel gear 26. However, since the driving threaded shaft 18 itself rotates back and forth, a single active bevel gear 27 can be continuously engaged with the driven bevel gear 26 to achieve the reciprocating rotation of the driven bevel gear 26. The meshing mode can be determined according to the number of rotations of the driving threaded shaft 18. When the driving threaded shaft 18 rotates multiple times during the movement of the slider 17, two active bevel gears 27 can be used, otherwise a single active bevel gear 27 can be selected.

[0033] An inclined guide plate 30 is fixedly connected to the lower inner wall of the mobile box 2, with the bottom of the inclined guide plate 30 facing the spiral auger 24. The inclined guide plate 30 guides the concrete or asphalt to the bottom, which facilitates the discharge of the spiral auger 24. The various components of the present application work in coordination, and the use effect is significantly improved. After the concrete or asphalt is laid, the concrete or asphalt can be compacted by a compacting device.

[0034] The side of the mobile box 2 is fixedly connected to a push handle 31, the bottom of the mobile base plate 1 is evenly connected to moving wheels 32, the mobile base plate 1 is also fixedly connected to a battery for driving the motor 4, and the side of the mobile box 2 is fixedly connected to a control panel.

[0035] Working principle: When in use, debug the device and push it to the position of the asphalt truck or concrete mixer truck, pour asphalt or concrete into the mobile box 2, then turn on the motor 4 and push the device to the position where the gap needs to be repaired. The rotation of the motor 4 drives the cleaning wheel 6 to rotate. While the cleaning wheel 6 rotates, the outer cleaning brush cleans the dust in the cracks. The rotation direction of the motor 4 is controlled so that the cleaning brush cleans the dust to the outside in a single direction. At the same time, the motor 4 drives the dust hood 7 to move back and forth. When the dust hood 7 moves to the end position, it moves downward due to the surface movement of the guide plate 8 at the end, so that the dust hood 7 can suck up the dust at a close distance. The edge of the ground gap is more likely to accumulate dust, and this structure can better clean it.

[0036] When the motor 4 rotates, it drives the active pulley 10 to rotate, which in turn drives the transmission belt 11 to rotate. The rotation of the transmission belt 11 drives the driven pulley 9 to rotate, which in turn drives the cleaning wheel 6 to rotate for cleaning. The incomplete gear 14 rotates continuously and drives the annular member 12 to move back and forth. The annular member 12 further drives the drive rack 15 to move back and forth. The drive rack 15 drives the driven gear 19 to rotate, which in turn drives the drive threaded shaft 18 to rotate back and forth. The drive threaded shaft 18 drives the slider 17 to move back and forth and simultaneously drives the dust hood 7 to move. The dust hood 7 is a prior art that provides a strong negative pressure through the motor to achieve dust collection. Its structure is similar to that of a vacuum cleaner. The dust hood 7 is connected to the slider 17 via a transmission rod 20. During the movement of the slider 17, the spring force of the torsion spring always contacts the upper surface of the guide plate 8. When the dust hood 7 moves to the middle position, it can fully absorb dust. The cleaning wheel 6 here has a better cleaning effect. However, at the corner position, the cleaning wheel 6 has a poor cleaning effect, so the dust hood 7 is used to supplement the suction to ensure the cleaning effect.

[0037] Open the end cap 25, and the concrete or asphalt will be discharged through the discharge pipe 22. The two active bevel gears 27 will alternately drive the driven bevel gear 26 to engage, causing the discharge shaft 23 to reciprocate and discharge the material. The reciprocating rotation of the discharge shaft 23 causes the concrete or asphalt to be periodically discharged outward in large quantities. When the spiral auger 24 transports the concrete inward, only a small amount of concrete will flow out of the gap. Therefore, during the gap between the discharge of concrete or asphalt, the device can be moved to the location where a large amount of concrete is needed, making it easier to lay the concrete and asphalt more evenly at different positions in the gap. The outer side of the discharge shaft 23 is connected to multiple scrapers 29 through the mounting sleeve 28. The scrapers 29 can scrape and level the discharged concrete during the reciprocating rotation. The size of the scrapers 29 can be set as needed to achieve the best leveling effect.
