Description

Technical Field

[0001] This utility model belongs to the field of highway compaction technology, specifically relating to a highway maintenance compaction device. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, landscaping and traffic monitoring facilities, as well as buildings, workshops, and other service facilities used for construction, maintenance, and monitoring.

[0003] When existing road rollers compact road materials such as asphalt and concrete repair materials using steel rollers, asphalt has strong adhesion at high temperatures, causing asphalt to easily stick to the roller surface. This not only affects construction efficiency but also negatively impacts compaction effect and road quality. Summary of the Invention

[0004] This utility model provides a compaction device for highway maintenance, which aims to solve the problem that when existing road rollers compact road materials such as asphalt and concrete repair materials through steel rollers, asphalt has strong adhesion at high temperatures, causing asphalt to easily stick to the roller surface, which not only affects construction efficiency but also has a negative impact on compaction effect and road quality.

[0005] This utility model provides a flattening device for highway maintenance, including two support plates, a compaction roller rotatably connected between the two support plates, a fixing mechanism on the support plates, and cleaning mechanisms installed on both sides of the compaction roller. The cleaning mechanisms pass through the support plates and are fixed by bolts.

[0006] Furthermore, the fixing mechanism includes two slides provided on opposite sides of the support plates, and a mounting groove is provided in the middle of the slides.

[0007] By adopting the above technical solution, the slide and the mounting groove can limit and support the cleaning mechanism, so that the compaction roller can be cleaned by the cleaning mechanism during the rolling process.

[0008] Furthermore, the cleaning mechanism includes two scrapers on the front and rear sides of the compaction roller. The two scrapers are connected by a fixing frame. Fixing rods are fixed on both sides of the fixing frame. The fixing rods extend toward the support plate and to the other side of the support plate. The fixing rods are fixed to the outer wall of the support plate by bolts.

[0009] By adopting the above technical solution, scrapers are set on both the front and rear sides of the compaction roller, which can effectively scrape off the adhering material when the compaction roller rotates forward or backward. At the same time, the scrapers can be fixed in the slide by the fixing frame and bolts.

[0010] Furthermore, both scrapers are inclined toward the compaction roller, and the surface of the scrapers is in contact with the compaction roller.

[0011] By adopting the above technical solution, the scraper is tilted at a certain angle towards the compaction roller, and the shearing force generated by the tilted surface is used to peel off the adhering material, which greatly improves the overall cleaning effect.

[0012] Furthermore, the mounting groove includes a first mounting groove, a second mounting groove, and a third mounting groove adapted to the fixed rod. The first mounting groove, the second mounting groove, and the third mounting groove are close to each other, and the height of the first mounting groove, the second mounting groove, and the third mounting groove is higher than the slide rail.

[0013] By adopting the above technical solution, the fixing rod can be placed in the first, second, or third mounting groove, thereby adjusting the fit between the scrapers on both sides and the compaction roller. At the same time, the height of the first, second, and third mounting grooves is higher than that of the slide rail, allowing the fixing rod to be adjusted in position.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Through the setting of the fixing mechanism, the slide and the mounting groove can limit and support the cleaning mechanism, so that the compaction roller can be cleaned by the cleaning mechanism during the rolling process.

[0016] 2. This utility model has a cleaning mechanism with scrapers on both the front and rear sides of the compaction roller, which can effectively scrape off the adhering material when the compaction roller rotates forward or backward. At the same time, the scrapers can be fixed in the slide by the fixing frame and bolts.

[0017] 3. With the setting of the mounting groove, the fixing rod can be placed in the first mounting groove, the second mounting groove or the third mounting groove, thereby adjusting the fit between the scrapers on both sides and the compaction roller, and adapting to the forward or reverse rotation of the compaction roller.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Reference Figure 1-4 This utility model embodiment proposes a flattening device for highway maintenance, including two support plates 1. The two support plates 1 are connected to an existing moving mechanism, which drags the support plates 1 to move, such as a moving vehicle. A compaction roller 2 is rotatably connected between the two support plates 1. A fixing mechanism 3 is provided on the support plates 1. The fixing mechanism 3 includes a slide rail 31 provided on the opposite side of the two support plates 1. A mounting groove 32 is provided in the middle of the slide rail 31. The slide rail 31 and the mounting groove 32 can limit and support the cleaning mechanism 4, so that the compaction roller 2 is cleaned by the cleaning mechanism 4 during the rolling process.

[0027] Reference Figure 1-4Cleaning mechanisms 4 are installed on both sides of the compaction roller 2. The cleaning mechanisms 4 pass through the support plate 1 and are fixed with bolts. The cleaning mechanism 4 includes two scrapers 41 on the front and rear sides of the compaction roller 2. The two scrapers 41 are connected by a fixing frame 42. Fixing rods 43 are fixed on both sides of the fixing frame 42. The fixing rods 43 extend towards the support plate 1 and to the other side of the support plate 1. The fixing rods 43 are fixed to the outer wall of the support plate 1 with bolts. Scrapers 41 are provided on both the front and rear sides of the compaction roller 2, which can effectively scrape off the adhering material when the compaction roller 2 rotates forward or backward. At the same time, the scrapers 41 can be fixed in the slide rail 31 by the fixing frame 42 and bolts. The fixing frames 42 on both sides of the scraper 41 extend into the slide rail 31. The slide rail 31 is fixed to the fixing frame 41. 2. Support is provided, and the length of the slide 31 is greater than the length of the fixed frame 42, which facilitates the fixed frame 42 to move a certain distance in the slide 31. At the same time, both scrapers 41 are inclined towards the compaction roller 2, and the surface of the scraper 41 is in contact with the compaction roller 2. The scraper 41 is inclined towards the compaction roller 2 at a certain angle, and the shearing force generated by the inclined surface is used to peel off the adhering material, which greatly improves the overall cleaning effect. When the compaction roller 2 rotates forward, the front scraper 41 can scrape off the material on the compaction roller 2. At this time, the scraped material can fall back onto the front side of the compaction roller 2, that is, the area waiting to be compacted, and wait to be compacted again. When the compaction roller 2 rotates in reverse, the rear scraper 41 can scrape off the material on the compaction roller 2 and then compact it again.

[0028] Reference Figure 1-4 The mounting groove 32 includes a first mounting groove 321, a second mounting groove 322, and a third mounting groove 323 adapted to the fixing rod 43. The first mounting groove 321, the second mounting groove 322, and the third mounting groove 323 are close to each other, and the height of the first mounting groove 321, the second mounting groove 322, and the third mounting groove 323 is higher than that of the slide rail 31. The fixing rod 43 can be placed in the first mounting groove 321, the second mounting groove 322, or the third mounting groove 323, thereby adjusting the fit between the scrapers 41 on both sides and the compaction roller 2. At the same time, the first mounting groove 321, the second mounting groove 322, and the third mounting groove 323 are adapted to the fixing rod 43. The height of groove 322 and the third mounting groove 323 is higher than that of slide rail 31, so that the position of fixing rod 43 can be adjusted. The positions of fixing rod 43 in the first mounting groove 321, the second mounting groove 322 and the third mounting groove 323 correspond to the rear scraper 41 being in contact with the compaction roller 2, the front and rear scrapers 41 not being in contact with the compaction roller 2, and the front scraper 41 being in contact with the compaction roller 2, respectively. When fixing rod 43 is fixed in the second mounting groove 322, the distance from the two scrapers 41 to the compaction roller 2 is equal to the distance from fixing rod 43 to the first mounting groove 321 or the second mounting groove 322.

[0029] The specific implementation method is as follows: In use, the support plate 1 is dragged to the designated position by the moving mechanism, and the position of the scraper 41 is adjusted according to the rotation direction of the compaction roller 2. When the moving mechanism pushes the compaction roller 2 to rotate forward, the fixing rod 43 is placed in the third placement groove 323. At this time, the front scraper 41 is in contact with the compaction roller 2. During the rotation of the compaction roller 2, the material adhering to the surface of the compaction roller 2 can be scraped off by the scraper 41 and fall into the waiting compaction area on the forward path of the compaction roller 2, waiting to be compacted by the compaction roller 2 again. When the moving mechanism drags the compaction roller 2 to rotate backward, the fixing rod 43 is placed in the first placement groove 321. At this time, the rear scraper 41 is in contact with the compaction roller 2. During the rotation of the compaction roller 2, the material adhering to the surface of the compaction roller 2 can also be scraped off by the scraper 41 and fall into the waiting compaction area on the forward path of the compaction roller 2, waiting to be compacted by the compaction roller 2 again. This greatly improves the overall construction efficiency while reducing material waste.
