Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a roadbed compacting device for road construction. Background Art

[0002] The roadbed in road construction is an important part of the road structure. It bears the gravity of the road surface and the traffic load transmitted by the road surface. The surface of the roadbed needs to be compacted during construction. For this purpose, a roadbed compaction device can be used. The roadbed compaction device is mainly divided into three types: rolling type, tamping type and vibration type. Most existing roadbed compaction devices use rollers to compact the roadbed.

[0003] When an existing roller compacts a roadbed, most of the dirt and other debris on the surface of the roadbed will adhere to the surface of the roller roller when the roller is compacting. However, the surface of the existing roller roller mostly needs to be cleaned manually, which is inconvenient to clean when the roller is compacting the roadbed. The debris attached to the surface of the roller roller will affect the compaction effect of the roadbed, resulting in an uneven surface of the roadbed after compaction. Therefore, the utility model provides a roadbed compacting device for road construction to meet the needs. Utility Model Content

There are two limit rods 15 in the dynamic connection, and the bottom ends of the two limit rods 15 are fixedly connected to the top rod 12; the scraper assembly is used to scrape and clean the debris on the surface of the roller of the roller body 1, and the scraper assembly is connected to the mounting frame 2 and the fixed plate 3 respectively. The front end of the roller body 1 is provided with a roller, and the mounting frame 2 is provided at the top of the roller. The outer wall of the mounting frame 2 is fixedly connected with multiple fixed plates 3 by bolts and nuts. The outer wall of the roller is provided with a fixing frame, and the top of the fixing frame is fixedly connected to the frame 13. The frame 13 is provided at the roller At the upper end, the mounting frame 2 is set to an arc shape, and a discharge groove is opened at the lower middle end of the mounting frame 2, so that the soil and other debris scraped off by the scraping assembly can be discharged from the middle of the front end of the roller through the discharge groove to prevent the scraped debris from being scattered everywhere and accumulating on the surface of the scraper. The outer walls of the two ends of the mounting frame 2 are fixed with connecting sleeves 11 by bolts and nuts. The outer walls of the two connecting sleeves 11 are fixed with push rods 12. The rod body of the push rod 12 is fixed with multiple clamping sleeves. A hydraulic cylinder 14 is fixed to the middle of the top of the frame 13. The lower end of the hydraulic cylinder 14 is connected to the middle of the rod body of the push rod 12. The frame 13 is connected to the clamping sleeve at the top, and the hydraulic cylinder 14 can drive the push rod 12 to move up and down, so that the mounting frame 2 drives the scraper assembly to move up and down, so that the two scrapers can be away from the surface of the roller, to prevent the scrapers from wearing against the roller when the roller is no longer working. At the same time, both sides of the top of the frame 13 are slid with limit rods 15, and the lower ends of the limit rods 15 are connected to the clamping sleeves at both ends of the push rod 12. The two limit rods 15 improve the stability of the mounting frame 2 when the mounting frame 2 is raised and lowered, so as to avoid affecting the stability of the scraper assembly on the mounting frame 2 when it moves.

[0034] As an implementation method in this embodiment, Figures 3 to 5As shown, the scraper assembly includes a bent plate 4 fixedly connected to the outer wall of the fixed plate 3, the other end of the bent plate 4 is fixedly connected to an arc-shaped scraper 5, the outer wall of the mounting frame 2 is fixedly connected to a bent rod 8, the other end of the bent rod 8 is fixedly connected to an arrow-shaped scraper 9, the plate bodies of multiple bent plates 4 are provided with weakening grooves 6, the rod body of the bent rod 8 is provided with multiple grooves 10, the plate bodies of multiple bent plates 4 are fixedly connected to arc plates 7, the other ends of multiple arc plates 7 are fixedly connected to the plate body of the fixed plate 3, the plate bodies of the two arc-shaped scrapers 5 are fixedly connected to baffles 16, the bent plate 4 is a C-shaped profile, the bent plate 4 is a curved elastic structure, the arc plate 7 is a curved elastic structure, the arc plate 7 has a downwardly convex profile, and multiple fixed plates The outer wall of 3 is fixedly connected with a bent plate 4, and a weakening groove 6 is opened in the middle of the top of the bent plate 4, and the bent plate 4 has a C-shaped profile and is set as a curved elastic structure. An arc scraper 5 is fixed to the other end of the bent plate 4. The bent plate 4 can drive the arc scraper 5 to expand outward under its own elasticity, so that the lower end inclined surface of the arc scraper 5 can fit the surface of the roller. The plate bodies of multiple fixed plates 3 are fixed with arc plates 7. The other end of the arc plate 7 is connected to the surface of the bent plate 4. The plate body thickness of the middle part of the bent plate 4 is less than the thickness of the plate body at both ends, so that the arc plate 7 can be bent. Under the restriction of the arc plate 7, the bent plate 4 is prevented from driving the arc scraper 5 to expand outward at a large angle. The two arc scrapers 5 are tilted and arranged on the roller The surface of the roller, at the same time, the lower ends of the two arc-shaped scrapers 5 are in contact with the surface of the roller. Under the action of the two arc-shaped scrapers 5, when the arc-shaped scrapers 5 clean the debris on the surface of the roller, the debris on the surface of the roller can be concentrated to the middle of the front end of the roller and discharged through the discharge trough at the front end of the mounting frame 2. One end of the two arc-shaped scrapers 5 is fixed with a baffle 16. The two baffles 16 can block the scraped debris and prevent the debris from falling from the two ends of the roller. At the same time, a bent rod 8 is fixed in the middle of the mounting frame 2. The bent rod 8 is set to an S-shaped profile, and a plurality of grooves 10 are provided at the top and bottom ends of the two bent rods 8. An arrow-shaped scraper 9 is fixed to the other end of the bent rod 8. The contour of the rod 8 and the multiple grooves 10 make the bent rod 8 have a certain elasticity, which can drive the arrow-shaped scraper 9 to fit closely to the middle of the surface of the roller. Under the action of the arrow-shaped scraper 9, the debris in the middle of the roller can be cleaned and scattered through the inclined surface of the arrow-shaped scraper 9, and the scattered debris can be discharged through the discharge trough of the mounting frame 2. The two arc-shaped scrapers 5 and the arrow-shaped scraper 9 can collect the soil and other debris on the surface of the roller to the middle of the roller after scraping, and drop from the middle of the front end of the roller, so as to avoid the debris scattered everywhere when the scraper cleans the surface of the roller, and accumulate on the scraper surface, affecting the cleanliness of the roadbed surface after compaction.

[0035] The working principle of the technical solution provided by the utility model is as follows:

[0036] During use, the staff can start the hydraulic cylinder 14 so that the hydraulic cylinder 14 can drive the mounting frame 2 to move through the top rod 12 and the connecting sleeve 11, driving multiple scrapers to fit the surface of the roller at the front end of the roller body 1. Under the elasticity of the bent plate 4, the two arc-shaped scrapers 5 can be fitted on the surface of the roller, which is convenient for improving the contact effect between the two arc-shaped scrapers 5 and the roller. Under the elasticity of the bent rod 8 and multiple grooves 10, the arrow-shaped scraper 9 can be driven to fit the middle of the roller, thereby improving the cleaning effect of the roller surface. The staff can start the roller body 1 so that the roller body 1 can drive the roller at the front end to move, thereby compacting the surface of the roadbed. During compaction, multiple scrapers are fitted on the surface of the roller, thereby cleaning the debris attached to the surface of the roller. The two arc-shaped scrapers 5 are in contact with the roller. When debris is scraped off the roller surface, the arc-shaped inclined surface at the lower end of the arc-shaped scraper 5 can fit into the surface of the roller, so that when cleaning debris, it can drive the debris to move toward the middle of the front end of the roller when cleaning debris, and under the action of the arrow-shaped scraper 9, the middle of the roller can be cleaned, and the debris can be scattered through the inclined surface of the arrow-shaped scraper 9. The scattered debris when the two arc-shaped scrapers 5 and the arrow-shaped scraper 9 are cleaning can be discharged through the discharge trough of the mounting frame 2 to avoid the scraper from cleaning the roller surface. At the same time, the baffles 16 at both ends of the two arc-shaped scrapers 5 can block the cleaned debris to prevent the cleaned debris from being scattered everywhere and affecting the neatness of the roadbed surface after compaction. At the same time, the two arc-shaped scrapers 5 and the arrow-shaped scraper 9 can also prevent the debris from accumulating on the surface of the scraper when the scraper is cleaning, affecting the cleaning effect of the scraper on the roller surface.

To provide a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments of this invention, but those skilled in the art will be able to fully understand this invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
