Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a hot rolling roller. Background Art

[0002] Hot rolling drum, as the working part of the roller, is widely used in filling and compaction operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, stadiums, etc. It can roll sandy, semi-sticky and sticky soils, roadbed stabilized soil and asphalt concrete pavement layers. With the gravity of the machine itself, it is suitable for various compaction operations, so that the rolled layer will produce permanent deformation and density. Considering the flexibility and portability of the roller, it is more convenient to operate at the construction site. The hot rolling drum is usually designed with a hollow structure in the center to reduce the overall weight of the hot rolling drum.

[0003] A common hot rolling roller is equipped with an eccentric mechanism inside. The centrifugal force generated by the rotation of the eccentric mechanism drives the hot rolling roller to vibrate and roll the road surface to compact and flatten the road surface. However, the eccentric mechanism usually has a fixed structure, the amplitude generated is fixed, and the vibration direction is always downward. If the road foundation is too soft, the road surface may become uneven. If the road foundation is too hard, the road surface may resonate and cause cracking and damage. It cannot meet the rolling requirements for compacting and leveling road foundations of different densities. Utility Model Content

[0031] Working principle:

[0032] In the utility model, during the forward movement of the rolling steel ring 2, the shaft motor drives the connecting shaft 4 to rotate. During the rotation of the connecting shaft 4, the centrifugal force generated by the rotation of the eccentric assembly causes the rolling steel ring 2 connected to the connecting shaft 4 to vibrate, which is used for vibration compaction and flattening of the road surface.

[0033] During the rotation of the eccentric assembly, the self-aligning weight 11 rolls in the self-aligning groove 10 under the action of the rotating centrifugal force, and always contacts the adjusting slide bar 12. By driving the motor 15 to rotate, the active semi-tooth plate 18 is driven to rotate. The active gear rod 20 on the active semi-tooth plate 18 is alternately engaged with the linkage gear rod 21, so that the transmission shaft 17 can reciprocate, that is, the reciprocating gear plate 19 engaged with the driving convex edge 13 is driven to reciprocate, and the self-aligning turntable 9 is driven to reciprocate on the eccentric sleeve 7, so that the adjusting slide bar 12 continuously slides back and forth in the self-aligning groove 10, which is used to adjust the position of the self-aligning weight 11 in the self-aligning groove 10, and can continuously change the center of gravity position of the eccentric assembly, so that the vibration generated by the rotating shaft mechanism during rotation is directed in different directions, thereby avoiding continuous depression or resonance damage of the road surface caused by the vibration direction always being kept vertical.

[0034] The aligning weight 11 slides in the aligning groove 10. Since the aligning groove 10 is arranged in a vortex shape, the aligning weight 11 changes the direction of the center of gravity and can change the distance between the center of gravity of the eccentric component and the axial center of the connecting shaft 4, thereby changing the vibration amplitude of the rolled steel ring 2.
