Description

Technical Field

[0001] This application relates to the field of road maintenance technology, specifically a crack repair and flattening device for highway maintenance. Background Technology

[0002] In the field of highway maintenance, regular treatment of pavement cracks is crucial to extending pavement lifespan and ensuring vehicle safety. Crack filler posts and crack filler adhesives are commonly used maintenance and repair tools and materials, and are widely applied in crack repair work.

[0003] Currently, Chinese utility model patent CN221460909U discloses a crack repair and flattening device for highway maintenance. This device fixes the main body of the crack-filling column to one side of a support frame. The user can push a handle to move the device, causing the column to move upwards along the crack's trajectory, filling the crack with extruded asphalt. It has advantages such as small size, portability, flexible steering, wide field of vision, and labor saving, effectively improving work efficiency and reducing labor costs.

[0004] However, in actual use, the device uses a pushing motion, causing the discharge end of the filler column to float above the crack. When the device moves, it's difficult to ensure precise alignment between the discharge end and the crack, easily causing filler displacement. Furthermore, because the filler is viscous, most of the poured filler only reaches the crack opening and cannot penetrate deep into the crack, resulting in unstable filler connections and affecting the crack repair effect and road surface restoration quality.

[0005] Therefore, this application provides a crack repair and flattening device for highway maintenance to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a crack repair and flattening device for highway maintenance, which aims to solve the problems mentioned in the background art, such as the easy suspension of the discharge end of the filler column body during use, which leads to the displacement of the filler.

[0007] To achieve the above objectives, this application provides the following technical solution: a crack repair and flattening device for highway maintenance, comprising a support frame and a filler column body disposed on the support frame. Tires are rotatably mounted on both sides of the bottom of the support frame. A support rod is fixedly connected to one end of the support frame near the filler column body, and a handle is fixedly connected to the top of the support rod. A guiding mechanism is provided on the support frame. The guiding mechanism includes a frame plate fixedly connected to the bottom of the support frame for scraping filler material from the outside of the crack, and a fixing plate fixedly mounted on the frame plate. A guide plate is inclinedly disposed at the bottom of the fixing plate for inserting into the crack opening. When repairing the crack, the bottom end of the frame plate abuts against the ground. The guide plate is triangular in shape, with one of its pointed ends facing the crack, and its opening abuts against the discharge end of the filler column body. By incorporating a guiding mechanism, where the guide plate is triangular in shape and its pointed end is inserted into the crack, the discharge end of the filler column remains aligned with the crack as the support frame moves, effectively preventing filler misalignment and precisely filling the crack, thus significantly improving filling efficiency. Simultaneously, the bottom of the frame plate abuts against the ground, allowing for timely scraping away of excess filler from the outside of the crack, ensuring the repaired filler surface is flush with the road surface, improving road smoothness and repair quality, and reducing driving safety hazards caused by filler protrusions.

[0008] Preferably, to encourage the filler to concentrate towards the center of the crack, the end of the frame plate furthest from the support has a triangular structure. This helps the filler to concentrate towards the center of the crack, preventing excessive accumulation of filler at the crack opening, resulting in a more uniform and reasonable distribution of the filler, enhancing the bonding strength between the filler and the crack, improving the stability and durability of the crack repair, and reducing premature damage to the repaired area due to uneven filler distribution.

[0009] Preferably, to facilitate adjustment of the insertion depth of the guide plate into the crack: a screw rod, rotatably connected to the guide plate, is threaded into the fixed plate via a threaded hole, and a handle is fixedly connected to the top of the screw rod. This allows for convenient adjustment of the insertion depth of the guide plate into the crack. The position of the guide plate can be flexibly adjusted according to cracks of different widths and depths, ensuring that the guide plate always accurately guides the discharge end of the filler column, allowing the filler to accurately fill the crack and improving the adaptability and repair effect of the device to cracks under different working conditions.

[0010] Preferably, shock-absorbing sleeves are fixedly fitted at both ends of the handle, and the outer surface of the shock-absorbing sleeves is provided with anti-slip texture. The shock-absorbing sleeves fixedly fitted at both ends of the handle can effectively buffer the vibration generated during the pushing process, reduce the impact of vibration on the hand, reduce operator fatigue, and improve operating comfort; the anti-slip texture on the outer surface of the shock-absorbing sleeve increases the friction between the hand and the handle, preventing the hand from slipping during pushing, and improving operating safety and stability.

[0011] Preferably, to ensure the filler penetrates deep into the crack: a striking mechanism is provided at the end of the frame plate away from the support frame. The striking mechanism includes a support plate fixedly mounted on the frame plate, a guide rail mounted vertically on the support plate, a slider slidably mounted on the guide rail, and a striking rod fixedly mounted on the slider. A drive motor is fixedly mounted at the top of the end of the support plate away from the guide rail. The output end of the drive motor passes through the support plate and is fixedly connected to a crank. A connecting rod, rotatably connected to the crank, is hinged to the top of the slider. Through the striking mechanism, the drive motor drives the striking rod to reciprocately strike the filler at the crack opening, causing the filler to move into the crack. This effectively solves the problem of filler only accumulating at the crack opening, ensuring the filler penetrates deep into the crack, enhancing the tightness of the bond between the filler and the crack wall, improving the firmness and integrity of the crack repair, and extending the service life of the repaired crack.

[0012] This application employs a guiding mechanism, in which a triangular guide plate is inserted into the crack. When the support frame moves the device, the discharge end of the filler column always aligns with the crack, effectively preventing filler misalignment and precisely filling the crack, thus greatly improving filling efficiency. Simultaneously, the bottom of the frame plate abuts against the ground, allowing for timely scraping away of excess filler from the outside of the crack, ensuring the repaired filler surface is flush with the road surface, improving road smoothness and repair quality, and reducing driving safety hazards caused by filler protrusions.

[0013] This application, through the setting of the striking mechanism, enables the driving motor to drive the striking rod to reciprocate to strike the filler at the crack end, causing the filler to move into the crack. This effectively solves the problem of filler only accumulating at the crack end, ensuring that the filler penetrates deep into the crack, enhancing the tightness of the bond between the filler and the crack wall, improving the firmness and integrity of the crack repair, and extending the service life after crack repair.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Example 1

[0021] This embodiment provides a crack repair and flattening device for highway maintenance, such as... Figure 1-3 As shown, the flattening device includes a support frame 1 and a filler column body 2 mounted on the support frame 1. Tires 3 are rotatably mounted on both sides of the bottom of the support frame 1. A support rod 4 is fixedly connected to one end of the support frame 1 near the filler column body 2, and a handle 5 is fixedly connected to the top of the support rod 4. A guide mechanism 6 is provided on the support frame 1. The guide mechanism 6 includes a frame plate 61 fixedly connected to the bottom of the support frame 1 for scraping the filler outside the crack, and a fixing plate 62 fixedly mounted on the frame plate 61. A guide plate 63 for inserting into the crack opening is inclined at the bottom of the fixing plate 62. When repairing the crack, the bottom end of the frame plate 61 abuts against the ground. The guide plate 63 is triangular in shape, and the pointed end of the guide plate 63 faces the crack, and the opening abuts against the discharge end of the filler column body 2. By setting a guiding mechanism 6, in which the guide plate 63 is triangular in shape, its pointed end is inserted into the crack. When the support frame 1 moves the device, it ensures that the discharge end of the filler column body 2 always corresponds to the crack, effectively preventing filler displacement and accurately filling the crack, greatly improving filling efficiency. At the same time, the bottom end of the frame plate 61 abuts against the ground, which can promptly scrape off excess filler outside the crack, ensuring that the surface of the repaired filler is flush with the road surface, improving road surface smoothness and repair quality, and reducing driving safety hazards caused by filler protrusion. In use, first install the filler column body 2 on the support frame 1, insert the discharge end into the open end of the guide plate 63, and then insert the bottom pointed end of the guide plate 63 into the crack. During the movement of the device, the guide plate 63 plays a guiding role, guiding the discharge end of the filler column body 2 to move along the crack trajectory; as the device moves, the bottom end of the frame plate 61 contacts the ground, scraping off excess filler outside the crack, achieving precise repair and surface smoothing of the crack.

[0022] Furthermore, to facilitate the aggregation of the filler towards the center of the crack, the end of the frame plate 61 furthest from the support frame 1 is triangular. This helps the filler to concentrate towards the center of the crack, preventing excessive accumulation of filler at the crack opening, resulting in a more uniform and reasonable distribution of the filler. This enhances the bonding strength between the filler and the crack, improves the stability and durability of the crack repair, and reduces premature damage to the repaired area due to uneven filler distribution. During the movement of the device, the triangular end of the frame plate 61 exerts a squeezing and guiding effect on the filler at the crack opening towards the center, changing the flow direction of the filler. This allows the filler to move and aggregate towards the center of the crack under its own weight and the squeezing action of the frame plate 61, achieving a uniform distribution of the filler.

[0023] Furthermore, to facilitate adjustment of the insertion depth of the guide plate 63 into the crack: a screw 64, rotatably connected to the guide plate 63, is threaded into a threaded hole on the fixed plate 62, and a handle 65 is fixedly connected to the top of the screw 64. This allows for convenient adjustment of the insertion depth of the guide plate 63 into the crack. The position of the guide plate 63 can be flexibly adjusted according to cracks of different widths and depths, ensuring that the guide plate 63 always accurately guides the discharge end of the filler column body 2, allowing the filler to accurately fill the crack and improving the adaptability and repair effect of the device to cracks under different working conditions. When it is necessary to adjust the depth of the guide plate 63, rotating the handle 65 drives the screw 64 to rotate. The screw 64 engages with the threaded hole on the fixed plate 62. When the screw 64 rotates clockwise, the guide plate 63 moves downward along the screw 64 under the limiting action of the discharge end of the filler column body 2 and the opening of the guide plate 63. When the screw 64 rotates counterclockwise, the guide plate 63 moves upward under the action of the threaded transmission, thereby realizing the precise adjustment of the insertion depth of the guide plate 63 into the crack.

[0024] Specifically, shock-absorbing sleeves 51 are fixedly fitted at both ends of the handle 5, and the outer surface of the shock-absorbing sleeves 51 is provided with anti-slip texture. The shock-absorbing sleeves 51 fixedly fitted at both ends of the handle 5 can effectively buffer the vibration generated during the pushing process, reduce the impact of vibration on the hand, reduce operator fatigue, and improve operating comfort. The anti-slip texture on the outer surface of the shock-absorbing sleeves 51 increases the friction between the hand and the handle 5, preventing the hand from slipping during pushing and improving operating safety and stability. When pushing the support frame 1 to move the device, uneven ground will cause the device to vibrate. The elastic material of the shock-absorbing sleeves 51 can absorb and buffer the vibration energy, reducing the vibration transmitted to the operator's hand. The anti-slip texture increases the roughness of the contact surface. According to the principle of friction, under a certain pressure, a rough surface can generate greater friction, thereby preventing the hand from sliding on the surface of the handle 5 and ensuring operating safety.

[0025] Example 2

[0026] Unlike Embodiment 1, to ensure the filler penetrates deep into the crack, a striking mechanism 7 is provided at the end of the frame plate 61 away from the support frame 1. The striking mechanism 7 includes a support plate 71 fixedly mounted on the frame plate 61, a guide rail 72 vertically mounted on the support plate 71, a slider 73 slidably mounted on the guide rail 72, and a striking rod 74 fixedly mounted on the slider 73. A drive motor 75 is fixedly mounted on the top of the end of the support plate 71 away from the guide rail 72. The output end of the drive motor 75 passes through the support plate 71 and is fixedly connected to a crank 76. A connecting rod 77, which is rotatably connected to the crank 76, is hinged to the top of the slider 73. Through the striking mechanism 7, the drive motor 75 drives the striking rod 74 to reciprocate and strike the filler at the crack opening, causing the filler to move into the crack. This effectively solves the problem of filler only accumulating at the crack opening, ensuring the filler penetrates deep into the crack, enhancing the tightness of the bond between the filler and the crack wall, improving the firmness and integrity of the crack repair, and extending the service life after crack repair. After the drive motor 75 is energized, its output end drives the crank 76 to rotate. As the crank 76 rotates circumferentially, the connecting rod 77 moves up and down in an arc shape under the hinge action of the slider 73 and the crank 76. Under the guidance of the guide rail 72, the slider 73 slides up and down along the guide rail 72, thereby driving the striking rod 74 fixed on the slider 73 to move up and down, realizing the reciprocating striking of the filler at the crack end, causing the filler to move into the crack under the action of impact force.

[0027] The wiring diagram of the drive motor 75 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the drive motor 75 will not be explained in detail.

[0028] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0029] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
