Description
Technical Field
The utility model relates to a road roller, the special bit is a road roller is used in bituminous paving construction.
Background
The asphalt concrete pavement refers to a pavement using asphalt concrete as a surface layer. The mixture is prepared by manually selecting mineral aggregate (crushed stone or crushed gravel, stone chips or sand, mineral powder and the like) with a certain gradation composition and a certain proportion of road asphalt material, and stirring under strictly controlled conditions. The mixture is spread and rolled to form the asphalt concrete pavement with stable performance.
The road roller is engineering equipment frequently used in the construction process of the asphalt concrete pavement, and compaction and flattening of the pavement are realized by back and forth rolling of a compression roller on the asphalt concrete. The existing problem is that the asphalt concrete has extremely high adhesiveness, when the roller rolls the asphalt concrete, a large amount of asphalt concrete materials are easily adhered to the surface of the roller, so that the surface of the roller is not smooth enough, and the rolling effect of the follow-up pavement is influenced.
The existing common road roller does not have a cleaning device on the surface of the compression roller, and can not clean impurities adhered to the surface of the compression roller in time, so that a worker can weld a scraping strip close to the surface of the compression roller on the road roller, and the scraping strip can scrape the impurities adhered to the compression roller when the compression roller rotates. However, because of the strong adhesiveness of asphalt, after the asphalt concrete on the compression roller is scraped, the asphalt concrete is easy to adhere to the scraping strip, and the amount of the asphalt concrete accumulated on the scraping strip is increased continuously along with the continuous rotation of the compression roller, so that the asphalt concrete on the scraping plate is brought into the gap between the scraping strip and the compression roller again by the asphalt concrete on the compression roller at the back, the mineral aggregate in the asphalt concrete continuously scrapes the scraping strip after entering the gap, the abrasion of the scraping strip is serious, the service life is affected, the replacement is required frequently, and the workload of workers is increased.
SUMMERY OF THE UTILITY MODEL
In view of the above, the utility model aims to provide a road roller is used in bituminous paving construction can strike off the asphalt concrete material of adhesion on the scraping strip fast, avoids remaining of asphalt concrete material, and then alleviates the wearing and tearing of mineral aggregate to the scraping strip in the asphalt concrete, prolongs the life of scraping the strip, reduces the workman because need change the work load of scraping the strip and producing.
In order to achieve the above purpose, the technical scheme of the utility model is that:
a road roller for asphalt pavement construction comprises

the scraping plate extends along the axial direction of the press roll, and two ends of the scraping plate are arranged on the scraping plate frame so that one side of the scraping plate is arranged close to the surface of the press roll;
cleaning device has can follow compression roller axial round trip movement's running gear and installs the scraper mechanism on running gear, running gear installs on scraping the plate holder, scraper mechanism laminating scraper blade sets up so that strike off the asphalt concrete material of adhesion on the scraper blade fast when reciprocating motion.
Preferably, the scraper holder comprises a body fixedly connected with the tong arm, a mounting groove is formed in the body, the two ends of the scraper are inserted into the mounting groove, the rear edge of the scraper is close to the surface of the compression roller, a locking bolt is screwed on the body, and one end of the locking bolt tightly presses the scraper in the mounting groove after entering the mounting groove.
Preferably, scraper mechanism includes scraper frame and scraper, scraper frame is connected with running gear transmission, the scraper is installed on scraper frame along scraper blade surface.
Preferably, the scraper is provided with a T-shaped chute, the scraper frame is rotatably provided with a rotating shaft, one end of the rotating shaft is provided with a hexagon head, the other end of the rotating shaft is coaxially connected with a screw rod, the screw rod is in threaded connection with a square nut, the square nut is arranged in the T-shaped groove in a sliding mode when the scraper is installed, and the rotating shaft is twisted to enable the square nut to abut against the groove wall of the T-shaped groove.
The working principle is as follows: the scraper is arranged on the scraper frame, the vehicle body can be driven to carry out road rolling operation after the gap between the scraper and the compression roller is adjusted, and in the road rolling process, the walking mechanism in the cleaning device drives the scraper mechanism to scrape back and forth on the surface of the scraper, so that asphalt concrete materials bonded on the scraper are cleaned in time.
Has the advantages that: the advantage of this scheme lies in striking off the back when the asphalt concrete material of scraper blade with compression roller surface adhesion, the scraper can in time be fallen with the asphalt concrete material clearance of adhesion on the scraper blade, avoid having the remaining of too much asphalt concrete material on the scraper blade, and reduced the possibility that the asphalt concrete material just can effectively be drawn into again between scraper blade and the compression roller to remain of asphalt concrete material, the scraper blade also can not continuously receive the friction of asphalt concrete material, its rate of wear can reduce, life just also can corresponding increase.
