Description

Technical Field

[0001] This utility model relates to the field of highway engineering maintenance and repair technology, specifically a highway engineering maintenance and repair leveling device. Background Technology

[0002] After a highway is built and opened to traffic, its quality gradually declines due to wear and impact from vehicle wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and melting ice, as well as human damage and defects left over from construction. Highway maintenance is the upkeep and repair of highways. Upkeep focuses on the entire process from the time the highway is built and opened to traffic, while repair focuses on the restoration of damaged parts. A road roller, also known as a soil compactor, is a type of road construction equipment, which is divided into steel wheel type and tire type. Road rollers belong to the category of road equipment in engineering machinery and are widely used in the filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can compact sandy, semi-cohesive, and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers. Road rollers use their own weight to compact various compaction operations, causing permanent deformation and densification of the compacted layer.

[0003] For the maintenance and repair of asphalt pavement, asphalt often needs to be compacted by a road roller during the laying process. However, for maintenance and repair, small asphalt potholes cannot be compacted by a large road roller. Not only is the cost prohibitive, but it is also very inconvenient to use a road roller to repair a road that has already been opened to traffic.

[0004] Therefore, a leveling machine is needed for filling and repairing small asphalt potholes to make the asphalt repair smoother. In addition, existing devices tend to have debris sticking to their surface during leveling, which affects the smoothness of the leveling. To address this issue, we propose a highway engineering maintenance and repair leveling device. Utility Model Content

[0005] The purpose of this utility model is to provide a road engineering maintenance and repair rolling device to solve the problems mentioned in the background art regarding the inadequacy of existing devices for repairing small asphalt potholes and the lack of cleaning mechanisms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a highway engineering maintenance and repair leveling device, including a connecting bracket, a leveling mechanism being provided on the surface of the connecting bracket, and a scraping mechanism being provided on the surface of the leveling mechanism;

[0007] The flattening mechanism includes a fixing block, which is fixed inside the connecting bracket. A handle is fixed to the surface of the connecting bracket, and a flattening roller is hinged to the surface of the connecting bracket.

[0008] The scraping mechanism includes a first connecting block, which is fixed to the bottom of a fixed block. A second connecting block is installed inside the first connecting block. A fixed plate is fixed to the bottom of the second connecting block, and a scraping block is fixed to the surface of the fixed plate.

[0009] Preferably, the connecting bracket has a trapezoidal structure, and the bottom ends of both sides of the connecting bracket are hinged with flattening rollers to facilitate repeated flattening of the pits.

[0010] Preferably, the fixing block is fixed in the middle of the inside of the connecting bracket, and the fixing block has a hollow structure to facilitate the addition of counterweight.

[0011] Preferably, two sets of handles are symmetrically arranged, and the handles are fixed to the top of the connecting bracket to facilitate the movement of the pushing device.

[0012] Preferably, a second connecting block is installed inside the first connecting block, and the second connecting block is fixed inside the first connecting block by two sets of bolts, which facilitates the replacement and maintenance of the fixing plate.

[0013] Preferably, the fixing plate is fixed to the bottom end of the second connecting block, and the fixing plate has a square through hole inside to prevent scraped debris from accumulating on the surface of the fixing plate.

[0014] Preferably, two sets of scraper blocks are symmetrically arranged on the surface of the fixed plate, and the scraper blocks abut against the surfaces of the two sets of flattening rollers to scrape off the debris on the flattening rollers.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The device is equipped with a connecting bracket and a handle, which, together with the rolling rollers, enable the device to fill small asphalt potholes and facilitate device maintenance. Pushing the handle allows the two sets of rolling rollers to repeatedly roll the filled asphalt potholes, improving the device's repair and maintenance effect on small potholes and increasing the device's working efficiency.

[0017] (2) The device is equipped with a first connecting block and a second connecting block, which, together with a fixing plate and a scraper, enable the device to scrape off the debris adhering to the surface of the flattening roller, thus preventing the debris from affecting the flattening effect. When the flattening roller rotates, the scraper will scrape off the debris and dirt on the surface of the flattening roller, thereby improving the working efficiency of the device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 An embodiment of this utility model is provided: a highway engineering maintenance and repair leveling device, including a connecting bracket 1, a leveling mechanism 2 provided on the surface of the connecting bracket 1, and a scraping mechanism 3 provided on the surface of the leveling mechanism 2.

[0026] The flattening mechanism 2 includes a fixing block 210, which is fixed inside the connecting bracket 1. A handle 220 is fixed on the surface of the connecting bracket 1, and a flattening roller 230 is hinged to the surface of the connecting bracket 1.

[0027] The scraping mechanism 3 includes a first connecting block 310, which is fixed to the bottom of the fixing block 210. A second connecting block 320 is installed inside the first connecting block 310. A fixing plate 330 is fixed to the bottom of the second connecting block 320. A scraper 340 is fixed to the surface of the fixing plate 330.

[0028] The connecting bracket 1 has a trapezoidal structure, and the bottom ends of both sides of the connecting bracket 1 are hinged with flattening rollers 230. The trapezoidal structure of the connecting bracket 1 allows the pressure inside the fixed block 210 to be more dispersed by the flattening rollers 230 after the addition of counterweights, thereby increasing the flattening pressure. The flattening rollers 230 are located on both sides, allowing them to repeatedly compact and repair asphalt potholes, thus improving compaction efficiency. The fixed block 210 is fixed in the middle of the connecting bracket 1. The fixed block 210 has a hollow structure, which facilitates the addition of counterweights inside the fixed block 210, making the flattening effect of the flattening rollers 230 even better. Two sets of handles 220 are symmetrically arranged and fixed at the top of the connecting bracket 1, allowing two people to pull the handles 220 back and forth from the left and right, enabling the connecting bracket 1 to reciprocate back and forth, thus improving the flattening effect of the flattening rollers 230.

[0029] The first connecting block 310 houses the second connecting block 320, which is secured to the first connecting block 310 by two sets of bolts. This facilitates quick disassembly of the second connecting block 320 and the fixing plate 330, making it easy to maintain and replace the scraper block 340. The fixing plate 330 is fixed to the bottom of the second connecting block 320. The fixing plate 330 has a square through hole inside to prevent scraped debris from accumulating on its surface. The through hole design allows scraped debris to fall to the ground. Two sets of scraper blocks 340 are symmetrically arranged on the surface of the fixing plate 330. The scraper blocks 340 abut against the surfaces of the two sets of flattening rollers 230. The symmetrical arrangement allows for simultaneous scraping of debris from both sets of flattening rollers 230. The two sets of scraper blocks 340 mounted on the fixing plate 330 make future maintenance more convenient. When the scraper block 340 needs to be replaced, the fixing plate 330 can be disassembled, allowing for the removal and replacement of the scraper block 340 together.

[0030] Working principle: When the device is working, a suitable counterweight is placed inside the fixed block 210 as needed. Then, the handle 220 is pushed so that the pit is located at the bottom of the fixed plate 330. Then, two people are needed to pull and push the handle 220 from the left and right to make the rolling roller 230 roll and move, repeatedly rolling the asphalt. When the rolling roller 230 rolls, the scraper 340 can scrape off the debris adhering to the surface of the rolling roller 230, preventing debris from adhering to the surface of the rolling roller 230. When the scraper 340 needs to be replaced, the bolts on the first connecting block 310 are removed, and the scraper 340 can be replaced. The above is the complete working principle of this utility model.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended features rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the features be included within this invention. The scope of this invention is defined by its equivalents.
