Description

Technical Field

[0001] The present application relates to the technical field of road construction equipment, and particularly relates to a crack repair device for road construction. Background Art

[0002] Road crack repair is an important task in road maintenance. The methods vary depending on the size, type of cracks and road surface materials. Different repair methods are required for road cracks of different widths. For micro-cracks less than 2 mm wide, sealants are usually used for surface sealing. For medium-sized cracks between 2 mm and 5 mm wide, modified emulsified asphalt or modified asphalt is usually used for grouting. For large cracks with a width greater than 5 mm, materials such as cement mortar are usually used for slot expansion grouting. The specific steps are as follows: Remove the debris in the crack and clean the loose crack edges, use an electric drill or a cutting machine to expand the crack into a "V" - shaped groove, then pour the cement mortar into the crack and perform a leveling treatment.

[0003] For the repair of large cracks, in the related art, a crack repair device is used for repair. For example, the utility model patent with the publication number CN218322275U discloses a crack repair device for road construction. The crack repair device drives a moving column to move in a card slot through a convex rod, so that the moving column synchronously drives a smoothing rod to move. At this time, the smoothing rod will drive the smoothing column to move synchronously, so that the smoothing columns at different positions level the uneven colloid on the crack surface, which is convenient for the subsequent repair of the crack.

[0004] The above-mentioned crack repair device levels the colloid on the crack surface through the smoothing column. However, in the actual repair process, after pouring the cement mortar into the crack, a large amount of cement mortar will overflow. After leveling with the smoothing column, a large amount of excess cement mortar will accumulate on the road surface, and the above-mentioned crack repair device cannot clean this part of the excess cement mortar, so it is necessary to consume manpower for cleaning, increasing the workload of the cleaning personnel. Utility Model Content

[0034] An embodiment of this application discloses a crack repair device for road construction.

[0035] A crack repair device for road construction includes a walking vehicle frame 10, a grouting mechanism 20, an aggregate hopper 30, a scraping mechanism, a scraper 40, a material bucket 50, and a transfer mechanism 60.

[0036] Refer to Figure 1 and Figure 2 The grouting mechanism 20 is arranged on the walking vehicle frame 10 and is used for injecting grouting material into road cracks. In an optional embodiment, the specific structure of the grouting mechanism 20 and its specific connection relationship with the walking vehicle frame 10 are as follows:

[0037] The grouting mechanism 20 includes a slurry storage tank 21, a grouting pipe 22, and a rotation driving member 23. The slurry storage tank 21 is fixedly arranged on the walking vehicle frame 10 and is used for storing grouting materials such as cement mortar required for road crack repair. A discharge port 211 is provided at the bottom of the slurry storage tank 21, and a blanking valve 24 is provided at the discharge port 211 of the slurry storage tank 21. The grouting pipe 22 is rotatably connected to the discharge port 211 of the slurry storage tank 21. After the blanking valve 24 is opened, grouting material can be injected into road cracks through the grouting pipe 22.

[0038] The rotation driving member 23 is arranged on the slurry storage tank 21 and is connected to the grouting pipe 22. More specifically, the rotation driving member 23 is a rotation driving motor, and a driving gear 25 is provided on the output shaft of the rotation driving motor. A driven gear 221 meshing with the driving gear 25 is provided on the grouting pipe 22.

[0039] Refer to Figures 1 to 4, the aggregate hopper 30 is arranged on the traveling frame 10 and can be laid on the road surface. The aggregate hopper 30 is a shell-like structure with one end open. The scraping mechanism is arranged on the traveling frame 10, and the scraper 40 is connected to the scraping mechanism. The scraping mechanism is used to drive the scraper 40 to scrape the excess grouting material into the aggregate hopper 30. In an alternative embodiment, the structure of the scraping mechanism and its connection relationship with the scraper 40 are as follows:

[0040] The scraping mechanism includes a translation driving member 70 and a vertical movement driving member 80. The translation driving member 70 is arranged on the traveling frame 10, and the vertical movement driving member 80 is connected to the translation driving member 70. The translation driving member 70 is used to drive the vertical movement driving member 80 to translate. The translation driving member 70 can adopt a linear screw translation module, and the vertical movement driving member 80 can adopt a linear screw vertical movement module. The scraper 40 is connected to the vertical movement driving member 80 through a pressing member 90, and the vertical movement driving member 80 is used to drive the scraper 40 to move vertically.

[0041] When it is necessary to drive the scraper 40 by the scraping mechanism to scrape the excess grouting material generated during the grouting process into the aggregate hopper 30, the aggregate hopper 30 is laid on the road surface. Then, the vertical movement driving member 80 is used to drive the scraper 40 to move vertically downward, so that the lower end of the scraper 40 contacts the road surface and is pressed through the pressing member 90. Then, the translation driving member 70 is used to drive the vertical movement driving member 80 and the scraper 40 to move towards the aggregate hopper 30, and the excess grouting material is pushed into the aggregate hopper 30 through the opening end of the aggregate hopper 30 by the scraper 40. Before the translation driving member 70 is started, the grouting pipe 22 is driven to rotate by the rotation driving member 23, so that the grouting pipe 22 is moved away from the moving path of the scraper 40 to avoid interfering with the movement of the scraper 40.

[0042] Refer to Figure 4 and Figure 5 , in an alternative embodiment, the specific structure of the pressing member 90 and the specific connection relationship among the scraper 40, the pressing member 90 and the vertical movement driving member 80 are as follows:

[0043] The pressing member 90 includes a sleeve 91, a telescopic rod 92, an elastic member and a scraper frame 93. The scraper frame 93 and the telescopic rod 92 are respectively hinged to the moving end 81 of the vertical movement driving member 80 through a first pin shaft 94 and a second pin shaft 95. The scraper 40 is fixedly connected to the scraper frame 93. The sleeve 91 is hinged to the scraper frame 93 through a third pin shaft 96 and is telescopically and slidably inserted into the telescopic rod 92.

[0044] The elastic member is arranged between the telescopic rod 92 and the sleeve 91 and is used to provide an elastic force to prevent the telescopic rod 92 from contracting relative to the sleeve 91. The elastic member can adopt a spring 97. More specifically, a limit plate 921 for restricting the separation of the telescopic rod 92 and the sleeve 91 is arranged on the telescopic rod 92, and a baffle 922 is arranged on the telescopic rod 92. The spring 97 is sleeved outside the telescopic rod 92, and the two ends of the spring 97 are respectively abutted against the baffle 922 and the sleeve 91.

[0045] The scraping plate 40 is composed of a main board 41 and side plates 42 fixedly arranged on both side parts of the main board 41. The included angle between the side plates 42 and the main board 41 is an obtuse angle. During the process of scraping the excess grouting material into the aggregate hopper 30 through the side plates 42 on both side parts of the main board 41, the grouting material can be limited to prevent the grouting material from flowing away from both sides of the scraping plate 40.

[0046] Refer to Figures 1 to 4 , the material bucket 50 is arranged on the traveling vehicle frame 10, the transfer mechanism 60 is arranged on the traveling vehicle frame 10 and is connected to the aggregate hopper 30. After the excess grouting material generated during the grouting process is scraped into the aggregate hopper 30 by driving the scraping plate 40 through the scraping mechanism, the grouting material in the aggregate hopper 30 can be transferred into the material bucket 50 through the transfer mechanism 60.

[0047] In an alternative embodiment, the specific structure of the transfer mechanism 60 and the specific connection relationships among the traveling vehicle frame 10, the transfer mechanism 60 and the aggregate hopper 30 are as follows:

[0048] The transfer mechanism 60 includes a lifting drive member 61, a bracket 62, a flipping drive member 63 and a pushing member 64. The lifting drive member 61 is arranged on the traveling vehicle frame 10, the bracket 62 is connected to the lifting drive member 61, and the lifting drive member 61 can adopt a screw jack.

[0049] The aggregate hopper 30 is rotatably arranged on the bracket 62. More specifically, pivot shafts 33 are arranged on both side parts of the aggregate hopper 30, and the aggregate hopper 30 is rotatably arranged on the bracket 62 through the pivot shafts 33. The flipping drive member 63 is arranged on the bracket 62 and is connected to the aggregate hopper 30. The flipping drive member 63 can adopt a flipping drive motor, and the flipping drive motor is connected to the pivot shaft 33 on one side part of the aggregate hopper 30.

[0050] The pushing member 64 is arranged on the traveling vehicle frame 10, the material bucket 50 is connected to the pushing member 64, and the pushing member 64 can adopt an electric push rod. A discharge port 31 is arranged on the aggregate hopper 30, and a valve 32 is arranged at the discharge port 31 of the aggregate hopper 30. The valve 32 can adopt an electric gate valve. When the aggregate hopper 30 is flipped and tilted, the pushing member 64 can push the material bucket 50 to below the discharge port 31, so that the grouting material inside the aggregate hopper 30 can be discharged into the material bucket 50 through the discharge port 31.

[0051] The implementation principle of a crack repair device for road construction in this embodiment is as follows: The grouting materials such as cement mortar required for road crack repair are stored in the slurry storage tank 21. When it is necessary to repair the road crack, the traveling vehicle frame 10 is towed by a towing vehicle to move, and the feeding valve 24 is opened. The grouting material is injected into the road crack through the grouting pipe 22. At the same time, the scraping plate 40 is driven by the vertical movement drive member 80 to move vertically downward, so that the lower end of the scraping plate 40 contacts the road surface and is pressed by the pressing member 90.

[0052] During the grouting process, a towing vehicle is used to tow the walking frame 10 to move, so as to change the grouting position. Meanwhile, the overflowing grouting material is leveled by the scraper 40. After the road crack is filled with grouting material, the grouting pipe 22 is rotated by the rotation driving member 23 to move the grouting pipe 22 away from the moving path of the scraper 40. Then, the aggregate hopper 30 is driven to move downward by the lifting driving member 61, so that the aggregate hopper 30 is attached to the road surface. Next, the vertical movement driving member 80 and the scraper 40 are driven to move towards the aggregate hopper 30 by the translation driving member 70, and the excess grouting material is pushed into the aggregate hopper 30 through the opening end of the aggregate hopper 30 by the scraper 40.

[0053] Then, the aggregate hopper 30 is driven to rise by the lifting driving member 61. Meanwhile, the aggregate hopper 30 is driven to turn and tilt by the turning driving member 63 to prevent the grouting material in the aggregate hopper 30 from flowing out. After the aggregate hopper 30 rises to a certain height, the material bucket 50 is pushed to below the discharge port 31 by the flat pushing member 64. Then, the valve 32 is opened, so that the grouting material inside the aggregate hopper 30 is discharged into the material bucket 50 through the discharge port 31.

[0054] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
