[0030] 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.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0032] Example 1: Please refer to Figure 1 and Figure 2A road crack treatment device includes a mobile box 1, the side wall of the mobile box 1 is rotatably connected to a swing arm 2, the side wall of the mobile box 1 is also provided with a driving component 3 for controlling the swing of the swing arm 2, the swing arm 2 is fixedly connected to a mounting platform 4, the mounting platform 4 is fixedly connected to a driving and regulating component 5, and a cleaning component 6 is provided at one end of the swing arm 2 away from the mobile box 1. The cleaning component 6 is driven by the driving and regulating component 5 for cleaning, and the driving and regulating component 5 includes a stroke control unit 7 for controlling the cleaning stroke of the cleaning component 6.

[0033] When using the device, turn on the driving and regulating component 5. After the driving and regulating component 5 is turned on, it drives the cleaning component 6 to work. The cleaning component 6 can clean the debris in the cracks, thereby ensuring the effect after the cracks are filled. After the stroke control unit 7 is turned on, it can control the cleaning stroke of the cleaning component 6, so that it can be controlled according to the size of the cracks to improve the cleaning effect.

[0034] The bottom of the mobile box 1 is fixedly connected to a number of moving wheels 8, which facilitate the movement of the pushing device. A push handle 9 is fixedly connected to the side wall of the mobile box 1, which is used for hand-held pushing. The side wall of the mobile box 1 is provided with a discharge port 10, and the inner wall of the mobile box 1 is provided with a gate 11 that cooperates with the discharge port 10. Concrete or asphalt is placed inside the mobile box 1 and then opened when needed to discharge the concrete or asphalt. To prevent the concrete or asphalt from solidifying inside the mobile box 1, a corresponding stirring mechanism can be provided on the side wall of the mobile box 1.

[0035] The drive assembly 3 includes an electric telescopic rod 12 fixed to the side wall of the mobile box 1. The end of the electric telescopic rod 12 is fixedly connected to a telescopic rack 13. The swing arm 2 is fixedly connected to a swing gear 14, and the telescopic rack 13 meshes with the swing gear 14. After the electric telescopic rod 12 is opened, it can be extended and retracted, which in turn drives the telescopic rack 13 to perform a reciprocating telescopic motion. Since the telescopic rack 13 meshes with the swing gear 14, the telescopic motion can drive the swing arm 2 to swing, and the cleaning assembly 6 will swing. When the cleaning assembly 6 needs to be raised, the drive assembly 3 can be controlled to operate, achieving corresponding motion control.

[0036] See also Figure 3 、 Figure 4 and Figure 5The driving and controlling component 5 includes a door frame 15 fixed on the mounting platform 4, a motor 16 is fixedly connected to the mounting platform 4, a rotating disk 17 is fixedly connected to the rotor of the motor 16, a swinging center shaft 18 is provided on the door frame 15, and a swinging rod 19 is connected to the top of the swinging center shaft 18 for damping sliding. The end of the swinging rod 19 close to the rotating disk 17 is fixedly connected to a waist-shaped groove transmission member 20. The waist-shaped groove transmission member 20 is a structural member with a waist-shaped groove in the center. An eccentric driving rod 21 is fixedly connected to the top of the rotating disk 17. The eccentric driving rod 21 is fixed at an eccentric position outside the rotating disk 17. The eccentric driving rod 21 is located in the waist-shaped groove transmission member 20. The other end of the swinging rod 19 is fixedly connected to a fork 22. When the fork 22 swings, it drives the cleaning component 6 to clean.

[0037] Turn on the motor 16, the motor 16 rotates to drive the rotating disk 17 to rotate, the rotating disk 17 rotates through the synchronously rotating eccentric drive rod 21 to drive the swing rod 19 to swing, the swing rod 19 swings around the swing center axis 18, thereby driving the fork 22 to swing, and the swing of the fork 22 drives the cleaning component 6 to move to perform cleaning.

[0038] See also Figure 5 and Figure 6 The travel control unit 7 includes a sliding base 23 that is slidably connected to the portal frame 15. The sliding base 23 is locked with the portal frame 15 via a locking screw 24. The swing center shaft 18 is rotatably connected to the sliding base 23. A sliding frame 25 is sleeved on the outer side of the swing center shaft 18 and is slidably connected to the portal frame 15. A control rod 26 is fixedly connected to the outer side of the swing center shaft 18. Photoelectric switches 27 are provided on the upper and lower sides of the inner side of the slide frame 25. During the swing process, the control rod 26 cooperates with the photoelectric switch 27 to realize the extension and retraction of the electric telescopic rod 12.

[0039] Adjusting the position of the sliding base 23 can change the position of the swing center axis 18. This change in the swing center axis 18 significantly alters the swing amplitude of the shift fork 22, thereby enabling the cleaning stroke of the cleaning assembly 6 to be varied. After the sliding base 23 has slid to its desired position, rotating the locking screw 24 locks the position of the sliding base 23. The swing arm 19 and the swing center axis 18 utilize damped sliding, allowing them to adjust their relative position under significant external forces. Damping prevents random sliding between the swing arm 19 and the swing center axis 18, and a screw can also be provided to lock the sliding relationship between the two. The sliding frame 25 adjusts as the position of the swing center axis 18 is adjusted. Photoelectric switches 27 are connected above and below the sliding frame 25. The control lever 26 swings synchronously with the swing center axis 18, and in conjunction with the photoelectric switch 27, controls the extension and retraction of the electric telescopic rod 12. By implementing a control program into the control system, the swing arm 2 is raised when it swings to a certain position and lowered when it swings to another position. This program control is conventional technology for those skilled in the art.

[0040] The main components of the photoelectric switch 27 include a transmitter, a receiver, a control unit, and a power supply. The bar-shaped structure depicted in the figure is a schematic diagram of the transmitter; other components are not shown. The swing control lever 26 is used to block the light signal emitted by the transmitter, preventing the receiver from receiving the corresponding light signal. Based on this basic principle, the real-time position of the swing arm 2 can be controlled by adjusting the position of the swing control lever 26 in conjunction with the extension and retraction of the electric telescopic rod 12. To facilitate adjustment of the controlled position, the swing control lever 26 can be connected to the swing center axis 18 using an adjustable fixed connection, such as a snap-fit ​​connection or a damped rotation connection, to maintain a fixed relative position between the two. As the relative position changes, the position of the swing control lever 26 can also be adjusted. It is clear that the photoelectric switch 27, in conjunction with the swing control lever 26, can adjust the position of the swing arm 2. The specific control method is the extension and retraction of the electric telescopic rod 12. Controlling the electric telescopic rod 12 is not difficult for those skilled in the art.

[0041] Example 2: This example makes the following improvements based on the previous example. Figure 7The cleaning assembly 6 includes a guide rod 28 fixedly connected to the swing arm 2, and a plurality of cleaning units 29 are slidably connected to the guide rod 28. The cleaning unit 29 includes a cleaning frame 30 slidably connected to the guide rod 28. When the shift fork 22 swings, it drives the cleaning frame 30 to slide along the guide rod 28 to achieve cleaning. The cleaning unit 29 includes a spiral drive shaft 31 rotatably connected to the cleaning frame 30, a driving gear 32, a driven gear 33 and a cleaning wheel 34. The driving gear 32 is fixedly connected to the outer side of the spiral drive shaft 31, and the driven gear 33 is rotatably connected to the cleaning frame 30. The driving gear 32 is meshed with the driven gear 33. The cleaning wheel 34 is coaxially fixed with the driven gear 33 and rotates synchronously with the driven gear 33. A spiral rod 35 is fixedly connected to the swing arm 2. The spiral drive shafts 31 in different cleaning units 29 are all threadedly engaged with the spiral rod 35. The bottom of the cleaning frame 30 is also fixedly connected to horizontal bristles.

[0042] As the fork 22 swings, the cleaning frame 30 slides back and forth along the guide rod 28, and the horizontal bristles at the bottom of the cleaning frame 30 can move horizontally to clean the floor. At the same time, due to the movement of the cleaning frame 30, the driving gear 32 rotates synchronously due to the threaded fit of the spiral drive shaft 31, and drives the driven gear 33 to rotate, which drives the cleaning wheel 34 to rotate rapidly. Since the cleaning wheel 34 rotates rapidly while moving horizontally, it can efficiently remove debris from the cracks, and the effect is better when combined with the horizontal bristles. When the fork 22 is reset, the cleaning wheel 34 will also reset synchronously. In order to avoid bringing debris into the gap, the electric telescopic rod 12 can be controlled to extend and retract so that it is located in the gap during cleaning. When resetting, the swing arm 2 is raised to avoid bringing debris into the gap. After a number of reciprocating cleaning cycles, the cracks can be filled, and the concrete or asphalt inside the mobile box 1 can be discharged into the gap.

[0043] The tops of the various cleaning units 29 are all fixedly connected to linkage posts 36, which are each connected to a linkage rod 37. One of the linkage posts 36 is located within the shift fork 22 and moves with the swinging movement of the shift fork 22. The arrangement of the linkage posts 36 and linkage rod 37 allows for the synchronized movement of the multiple cleaning units 29, thereby providing higher cleaning efficiency. Due to the structural arrangement of the linkage posts 36 and linkage rod 37, the relative positions of the multiple cleaning units 29 are determined. When the shift fork 22 drives one of the cleaning units 29 to move, it also drives the synchronized movement of the multiple cleaning units 29, significantly improving cleaning efficiency.

[0044] Working principle: When using the device, turn on the drive control component 5. After the drive control component 5 is turned on, it drives the cleaning component 6 to work. The cleaning component 6 can clean the debris in the cracks, thereby ensuring the effect of filling the cracks. After the stroke control unit 7 is turned on, it can control the cleaning stroke of the cleaning component 6, so that it can be controlled according to the size of the cracks to improve the cleaning effect. After the electric telescopic rod 12 is turned on, it can be extended and retracted, and then drive the telescopic rack 13 to perform reciprocating telescopic motion. Since the telescopic rack 13 is engaged with the swing gear 14, it can drive the swing arm 2 to swing during the telescopic motion, and the cleaning component 6 will swing. When the cleaning component 6 needs to be lifted, the drive component 3 can be controlled to operate to achieve corresponding action control.

[0045] Turn on the motor 16, and the rotation of the motor 16 drives the rotating disk 17 to rotate. The rotation of the rotating disk 17 drives the swing rod 19 to swing through the synchronously rotating eccentric drive rod 21. The swing rod 19 swings around the swing center axis 18, thereby driving the fork 22 to swing. The swing of the fork 22 drives the cleaning component 6 to move to perform cleaning. The position adjustment of the sliding base 23 can change the position of the swing center axis 18. When the position of the swing center axis 18 changes, the swing amplitude of the fork 22 will change significantly, and the cleaning stroke of the cleaning component 6 can be changed based on this. After the sliding base 23 slides to the corresponding position, the position of the sliding base 23 can be locked by rotating the locking screw 24. The swing rod 19 and the swing center axis 18 adopt damping sliding. The relative position can be adjusted under the action of a large external force. The random sliding between the swing rod 19 and the swing center axis 18 is avoided by damping, and the sliding relationship between the two can also be locked by setting a screw.

[0046] The slide frame 25 adjusts as the position of the swing center shaft 18 is adjusted. Photoelectric switches 27 are connected above and below the slide frame 25. As the swing center shaft 18 swings, the control lever 26 swings synchronously. In conjunction with the photoelectric switch 27, the electric telescopic rod 12 can be extended and retracted. By incorporating a control program into the control system, the swing arm 2 is raised when it swings to a certain position and lowered when it swings to another position. This program control is known to those skilled in the art.

[0047] As the fork 22 swings, the cleaning frame 30 slides back and forth along the guide rod 28, and the horizontal bristles at the bottom of the cleaning frame 30 can move horizontally to clean the floor. At the same time, due to the movement of the cleaning frame 30, the driving gear 32 rotates synchronously due to the threaded fit of the spiral drive shaft 31, and drives the driven gear 33 to rotate, which drives the cleaning wheel 34 to rotate rapidly. Since the cleaning wheel 34 rotates rapidly while moving horizontally, it can efficiently remove debris from the cracks, and the effect is better when combined with the horizontal bristles. When the fork 22 is reset, the cleaning wheel 34 will also reset synchronously. In order to avoid bringing debris into the gap, the electric telescopic rod 12 can be controlled to extend and retract so that it is located in the gap during cleaning. When resetting, the swing arm 2 is raised to avoid bringing debris into the gap. After a number of reciprocating cleaning cycles, the cracks can be filled, and the concrete or asphalt inside the mobile box 1 can be discharged into the gap.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.

[0049] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
