Description

Technical Field

[0001] The utility model relates to the technical field of road surface compaction, in particular to a road surface compaction device for highway paving. Background Art

[0002] Compactors belong to the category of road equipment in engineering machinery and are widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, etc. They can compact sandy, semi-cohesive and cohesive soils, roadbed stabilized soils and asphalt concrete pavement layers.

[0003] When paving a highway, the road surface under construction needs to be compacted to improve the flatness and construction quality of the road surface. However, in the road surface compaction device in the prior art, during the process of compacting the road surface, asphalt or other mixtures usually stick to the compacting wheel, making the surface of the compacting wheel not smooth enough, resulting in poor flatness of the compacted road surface. For this reason, a scraper is usually provided on the compacting wheel to remove the material stuck on the compacting wheel. When the scraper scrapes off the material stuck on the compacting wheel, since the scraper is in a fixed state, the material will adhere to the scraper. When the asphalt or concrete dries on the scraper, the scraping surface of the scraper will be rough, affecting the cleaning effect of the compacting wheel. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-5 As shown, the utility model provides a road surface compacting device for highway paving, comprising a frame 1, the frame 1 is arranged on an external road roller, and further comprises:

[0028] A compacting component, which is arranged on the frame 1 and is used for compacting the road surface;

[0029] The compacting component includes a rotating shaft 2, which is sleeved on the bottom of the frame 1, and a compacting cylinder 3 is installed on the outer surface of the rotating shaft 2. Two sets of fixing plates 4 are installed on one side of the frame 1, and a first scraper 5 is installed between the two sets of fixing plates 4.

[0030] A cleaning component, which is arranged on the compacting component and is used to remove the material stuck on the surface of the first scraper 5;

[0031] Among them, the cleaning component includes a first slot 6, the first slot 6 is opened inside the fixed plate 4, a fixed shaft 7 is installed inside the first slot 6, a movable frame 8 and a first spring 9 are sleeved on the outer surface of the fixed shaft 7, a second scraper 10 is installed on one side of the movable frame 8, and also includes a cam 11, which is installed on the outer surface of the rotating shaft 2.

[0032] When the compacting cylinder 3 compacts the road surface, it will rotate by itself and drive the cam 11 to rotate through the rotating shaft 2, so that the movable frame 8 can be driven to move along the outer surface of the fixed shaft 7 through the cooperation between the cam 11 and the movable frame 8. At the same time, the movement of the movable frame 8 will drive the second scraper 10 to scrape off the material sticking to the surface of the first scraper 5, and then when the first scraper 5 scrapes off the material on the surface of the compacting cylinder 3, it can prevent the material from drying on the surface of the first scraper 5.

[0033] like Figure 1 , 4 As shown, the first scraper 5 includes a fixed scraper 51 and a movable scraper 52 . The fixed scraper 51 is installed between two groups of fixed plates 4 . The movable scraper 52 is slidably matched with the fixed scraper 51 , and the movable scraper 52 is in contact with the compacting cylinder 3 .

[0034] Through the cooperation between the movable scraper 52 and the fixed scraper 51, the movable scraper 52 can slide along the end of the fixed scraper 51, so that when the movable scraper 52 is worn, the movable scraper 52 can be replaced.

[0035] like Figure 5 As shown, a second slot 12 is provided inside the fixing plate 4, a connecting shaft 13 is installed inside the second slot 12, a baffle 14 is installed at the bottom end of the connecting shaft 13, a second spring 15 is sleeved on the outer surface of the connecting shaft 13, and a threaded rod 16 is threadedly connected to the inside of the second slot 12.

[0036] Through the cooperation between the threaded rod 16 and the second slot 12, the threaded rod 16 can rotate and move up and down along the inside of the second slot 12, so as to apply a thrust to the baffle 14. By pushing the baffle 14, the baffle 14 is separated from the movable scraper 52, so that the movable scraper 52 can be replaced through the cooperation between the movable scraper 52 and the fixed scraper 51.

[0037] like Figure 3 As shown, the first spring 9 is elastically supported between the first notch 6 and the movable frame 8 .

[0038] Through the design of the first spring 9, the movable frame 8 has good elastic reset performance. At this time, since the first spring 9 is in a compressed state, an elastic force is applied to the movable frame 8, so that when the cam 11 releases the squeeze on the movable frame 8, the first spring 9 can push the movable frame 8 to reset.

[0039] like Figure 2 , 4 As shown, the cam 11 is in press contact with the movable frame 8 , and the top end of the second scraper 10 is in contact with the movable scraper 52 .

[0040] Through the cooperation between the cam 11 and the movable frame 8, when the cam 11 squeezes the movable frame 8, it will drive the movable frame 8 to move along the outer surface of the fixed shaft 7, so that the second scraper 10 can be driven to scrape the material on the surface of the movable scraper 52, and the reciprocating motion of the second scraper 10 can shake off the material sticking to itself.

[0041] like Figure 5 As shown, the threaded rod 16 is in compression contact with the baffle 14 , and the baffle 14 can block the movable scraper 52 when the movable scraper 52 slides along the end of the fixed scraper 51 .

[0042] Through the cooperation between the threaded rod 16 and the baffle 14, when the threaded rod 16 squeezes the baffle 14, the baffle 14 will be driven to move downward, so that the baffle 14 separates the movable scraper 52, and the movable scraper 52 is conveniently separated from 21 through the cooperation between the movable scraper 52 and the fixed scraper 51, so as to facilitate its disassembly.

[0043] like Figure 5 As shown, the second spring 15 is elastically supported between the second notch 12 and the connecting shaft 13 .

[0044] The design of the second spring 15 allows the connecting shaft 13 to have good elastic reset performance. At this time, since the second spring 15 is in a compressed state, an elastic force is applied to the connecting shaft 13, so that the baffle 14 can be driven to move upward through the connecting shaft 13, and the movable scraper 52 can be blocked by the baffle 14.

[0045] Working principle:

[0046] When the staff controls the compacting drum 3 to compact the road surface through the road roller, the compacting drum 3 will rotate and drive the cam 11 to rotate through the rotating shaft 2. At this time, the movable scraper 52 will scrape off the material sticking to the surface of the compacting drum 3. At the same time, through the cooperation between the cam 11 and the movable frame 8, the movable frame 8 is driven to move along the outer surface of the fixed shaft 7. At this time, the movement of the movable frame 8 will drive the second scraper 10 to scrape off the material sticking to the surface of the first scraper 5.
