Description

Technical Field

[0001] This utility model relates to the field of highway engineering maintenance equipment, specifically a foldable flattening component for highway engineering maintenance. Background Technology

[0002] In my country's road construction, semi-rigid base concrete pavement is generally chosen. This type of pavement has poor bending resistance and poor temperature adaptability. First, temperature changes can cause cracks. If the temperature rises or falls sharply, or if there is a sustained high or low temperature, cracks may appear in the concrete pavement. Second, if the total load of vehicles exceeds the maximum bearing capacity of the road pavement and exceeds its maximum bending performance, the repeated action of vehicles will cause the pavement layer to break. For the cracks that appear on the pavement, road maintenance projects need to repair them. Existing crack repair devices repair cracks by filling the cracks with materials. However, direct filling will cause uneven material at the crack ends, resulting in an uneven pavement after repair, affecting the smoothness of the road. Moreover, repair workers may not be able to accurately judge the direction of crack repair due to obstructed vision.

[0003] To address the aforementioned issues, a search revealed Chinese patent CN216338934U, which discloses a crack repair device for highway maintenance. The device includes pouring filler material into a container, with a worker holding a connecting handle to move the container along the cracked road surface. Several sets of discharge rollers are provided, with gaps between them, allowing the filler material to flow into the crack. As the container moves, the discharge rollers roll along the crack, facilitating the flattening of the material at the crack's edge and improving the smoothness of the repaired road surface.

[0004] Although the above-mentioned device can further scrape the flattened material with the arc-shaped scraper end to improve the uniformity of the filling material, in actual use, the length of the connecting straight rod (handle) is relatively long, which causes the overall size of the equipment to exceed the loading range of conventional transportation vehicles, increasing transportation costs; when storing, a large space needs to be reserved separately, which will encroach on the storage space of other equipment and reduce retrieval efficiency when space is limited in warehouses or maintenance stations.

[0008] Preferably, the adjusting seat has two sets of through holes, and adjusting bolts are inserted into the interior of both sets of through holes. The adjusting bolts pass through the through holes on the adjusting seat and are fixedly installed by two sets of locking nuts.

[0009] Preferably, the flattening sheet A and flattening sheet B are arranged in a "V" shape, with the bottom of flattening sheet A and flattening sheet B arranged horizontally, and a docking frame is fixedly provided at the end of flattening sheet A and a docking sheet is fixedly provided at the end of flattening sheet B.

[0010] Preferably, the cross-section of the docking frame is U-shaped, the dimensions of the docking frame and the docking piece are matched, the docking piece is inserted into the inside of the docking frame, and the spacing between the flattening piece A and the flattening piece B is adjusted by adjusting bolts, threaded sleeves, locking nuts, adjusting seats and fixing seats.

[0011] Preferably, the mounting base is a right-angled trapezoid with a screw hole, and a screw post is installed at the end of the support rod. The screw post is screwed into the screw hole, and slots are provided on both the support rod and the folding operating rod.

[0012] Preferably, the support rod and the folding operating rod are folded together. A positioning stud is installed on the side of the support rod away from the mounting base. The positioning stud passes through the receiving hole and is screwed and fixed with the positioning nut. The receiving hole is strip-shaped. A locking pin is fixedly connected to the end of the support rod. A locking groove is opened inside the folding base. A locking pin is inserted inside the locking groove. The length of the locking pin is less than the length of the receiving hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model utilizes a locking pin at the end of the support rod to pull out from inside the locking groove, while a positioning stud moves from top to bottom inside the receiving hole. When the locking pin is completely pulled out from inside the locking groove, the folding operation of the support rod and the folding operating rod is completed. After folding, the overall size of the assembly is reduced, facilitating movement and storage. The length of the support rod and the folding operating rod can be significantly shortened after folding, making it easy to fit into the trunk of a maintenance vehicle, tool bag, or backpack, especially suitable for narrow urban roads and scattered work sites on rural roads. A single person can easily carry multiple sets of this equipment, reducing reliance on large transportation vehicles. No large space needs to be reserved for storage, avoiding affecting the storage and retrieval efficiency of other equipment.

[0015] 2. This utility model utilizes a "V"-shaped leveling groove between leveling plate A and leveling plate B to mechanically compress the filler into the narrow area of ​​the crack, ensuring that the filler completely fills the crack cavity and forms a continuous and dense sealing layer. The opening width between leveling plate A and leveling plate B can be adjusted to match cracks of different widths, such as micro cracks, medium cracks, and even locally widened cracks. Without the need to replace equipment or accessories, the same leveling head can cover multiple crack types, reducing equipment investment costs and improving construction efficiency.

[0023] Please see Figure 1-6 This utility model provides a folding leveling component for highway engineering maintenance, including a leveling head 1, a support rod 2 installed at the end of the leveling head 1, a folding operation rod 3 installed on the side of the support rod 2 away from the leveling head 1, a folding seat 32 provided at the end of the folding operation rod 3, a receiving hole 31 opened on the side wall of the folding seat 32, a locking post 200 provided inside the folding seat 32, a mounting seat 17 fixedly connected to the end of the support rod 2 away from the folding seat 32, a fixing seat 19 fixedly provided at the end of the mounting seat 17, a leveling piece A11 fixedly provided on the surface of the fixing seat 19, a leveling piece B14 provided on one side of the leveling piece A11, an adjusting seat 15 fixedly connected to the end of the leveling piece B14, a folding column 33 fixedly installed on the surface of the folding seat 32, and a handle 34 installed at the end of the folding column 33 away from the folding seat 32.

[0024] Working Principle: In actual use, the filler is first placed into the road crack. The handle 34 is held to push the leveling head 1 on the ground. The leveling head 1 is equipped with leveling plates A11 and B14, arranged in a "V" shape. A "V"-shaped leveling groove is formed between the leveling plates A11 and B14, wrapping around the filler. This allows the leveling head 1 to fill the road crack with the filler, using mechanical thrust to compress the filler into the narrow area of ​​the crack, ensuring complete filling of the crack cavity and forming a continuous, dense sealing layer. The opening width between leveling plates A11 and B14 can be adjusted. Specifically, the mating plate 13 is inserted into the mating frame 12. After adjusting the opening width between leveling plates A11 and B14, the two adjusting seats 15 are... Tightening the locking nut 16 on the adjusting bolt 18 on the side allows for quick adjustment of the opening width between the leveling plates A11 and B14. By adjusting the spacing between leveling plates A11 and B14, the opening width of the "V"-shaped leveling groove can be changed to match cracks of different widths, such as micro cracks, medium cracks, and even locally widened cracks. No equipment or accessories need to be replaced; the same leveling head can cover multiple crack types, reducing equipment investment costs and improving construction efficiency. A narrow spacing between leveling plates A11 and B14 is suitable for narrow cracks, precisely pushing the filler into the narrow gap by reducing the groove width, preventing material accumulation on the surface. A wide spacing between leveling plates A11 and B14 is suitable for wide cracks or irregular openings, allowing more filler to enter the crack through the leveling groove, ensuring full filling inside the road crack.

[0025] When the device is not in use or is stored, loosen the positioning nut 22 and move the support rod 2 outward, so that the locking pin 200 at the end of the support rod 2 is pulled out from the inside of the locking groove 300. At the same time, the positioning pin 21 moves from top to bottom inside the receiving hole 31. When the locking pin 200 is completely pulled out from the inside of the locking groove 300, the folding operation rod 3 can be folded. After folding, the size of the entire component can be reduced, making it easier to move and store. The length of the support rod 2 and the folding operation rod 3 can be significantly shortened after folding, making it easy to put into the trunk of a maintenance vehicle, tool bag or backpack, especially suitable for narrow urban roads and scattered work points on rural roads. A single person can easily carry multiple sets of this equipment, reducing reliance on large transportation vehicles and reducing the logistical costs of working in remote areas.
