Description

Technical Field

[0001] The utility model belongs to the technical field of road rollers, in particular to an adjustable double-steel wheel road roller frame. Background Art

[0002] Steel wheel rollers are mechanical devices that use their own gravity and vibration to compact various construction and road building materials. In highway construction, vibrating rollers are most suitable for compacting non-cohesive soils, gravel, gravel mixtures, and various asphalt concrete materials, and are therefore widely used.

[0003] Traditional rollers, especially twin-wheel vibratory rollers, generally use articulated steering. The fixed frame usually cannot flexibly change direction and turn when facing a small road surface. The lack of steering control accuracy will bring inconvenience to the normal operation of the roller, the working efficiency of the roller cannot be improved, and the compaction effect of the road surface may be affected. Therefore, we proposed an adjustable twin-wheel roller frame. Utility Model Content

By setting a rotating component, the roller can easily cope with complex construction environments, such as narrow roads, curves or areas that require frequent turning, and can cover the entire working area more efficiently, reducing repeated compaction and omissions, thereby improving construction efficiency, and solving the existing problems of being unable to flexibly change direction and turn when facing a small road surface, the lack of steering control accuracy will bring inconvenience to the normal operation of the roller, the inability to improve the working efficiency of the roller, and the possible impact on the compaction effect of the road surface.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

The extended end of the transmission shaft 304 is fixedly connected to a support frame 306. By setting the rotating component 3, specifically by controlling the rotation of the transmission shaft 304, the support frame 306 is driven to rotate, and then the steering of the front steel wheel 105 of the frame is controlled. Flexible steering enables the roller to easily cope with complex construction environments, such as narrow roads, curves or areas that require frequent steering, and can cover the entire working area more efficiently, reduce repeated compaction and omissions, thereby improving construction efficiency.

[0033] Two limiting rods 403 are fixedly connected to one side of the sliding rod 402 close to the support frame 306.

As the column 404 rotates, the limiting rod sliding rod 402 moves back and forth left and right on the inner wall of the U-shaped frame 401 through the limiting rod 403, thereby driving the scraper 406 to scratch the surface of the steel wheel 105. Regular cleaning can ensure that the roller can compact the road surface quickly and effectively during operation, thereby improving construction efficiency.

[0035] A specific application of this embodiment is: using the oil cylinder 103 to push the sliding frame 104 to slide in the sliding groove 102 opened on the side wall of the fixed frame 1, thereby adjusting the position of the steel wheel 105. By adjusting the wheelbase, it can adapt to different construction needs and ensure that the compaction effect is optimal. The turntable 201 drives the connecting block 203 to rotate through the connecting rod 202. When the connecting block 203 rotates, it drives the sliding rod 205 to rotate through the rotating block 204, thereby driving the rack 301 to slide on the surface of the T-shaped sliding rod 303. As the rack 301 moves, it drives the gear 302 to rotate, thereby driving the transmission shaft 304 to rotate. By controlling the rotation of the transmission shaft 304, the support frame 306 is driven to rotate, thereby controlling the steering of the front steel wheel 105 of the frame. Flexible steering enables the roller to easily cope with complex construction environments, such as narrow roads, curves or areas that require frequent turning. It can cover the entire working area more efficiently, reduce repeated compaction and omissions, and thus improve construction efficiency.

[0036] As the roller is moving, the steel wheel 105 rotates, driving the columns 404 on both sides to rotate. The limit grooves 405 opened on the columns 404 are wavy, and the limit rods 403 slide on the inner walls of the limit grooves 405. As the columns 404 rotate, the limit rod sliding rods 402 move back and forth left and right on the inner wall of the U-shaped frame 401 through the limit rods 403, thereby driving the scraper 406 to scrape the surface of the steel wheel 105. Excessive impurities adhere to the surface of the steel wheel 105, which will affect the compaction speed and effect of the roller, thereby extending the construction period. Regular cleaning can ensure that the roller can compact the road surface quickly and effectively during operation, thereby improving construction efficiency.
