Pavement rolling device for road and bridge construction
The invention discloses a road surface rolling device for road and bridge construction. The road surface rolling device comprises a supporting frame, a traction head is arranged on one side of the supporting frame, rotating shafts are rotationally arranged on the two sides of the supporting frame, a pressing roller is arranged between the rotating shafts, rolling columns are evenly and rotationally arranged on the pressing roller in the circumferential direction, and rolling limiting devices capable of limiting rotation of the rolling columns are arranged at the two ends of the pressing roller. Under the traction effect of a tractor, the roller can roll on graded fine stones, and when graded coarse stones need to be rolled, an electric telescopic rod controller is operated to control an ejector rod of an electric telescopic rod to stretch out until a roller seat is tightly pressed on a pressing ring, and a first friction ring tightly presses a second friction ring, so that the state of the roller in a roller groove is stabilized, and the rolling effect of the roller is improved. The reversing valve is operated, so that the ejector rod of the hydraulic cylinder retracts, the pressing plate loses abutting pressing on the rotating shaft, at the moment, under traction of the tractor, the pressing roller can roll on the graded rubble layer, switching of the two modes is achieved, and the adaptation degree is high.
本发明公开了一种道桥施工用路面滚压装置，包括支撑架，支撑架的一侧设置有牵引头，支撑架的两侧转动设置有旋轴且旋轴之间设置有压辊，压辊上环向均匀转动设置有滚柱，压辊的两端设置有可限制滚柱旋转的限滚装置。在牵引车牵引作用下，使得滚柱能够在级配细石子上滚压，而需要对级配粗石子滚压时，通过操作电动伸缩杆控制器控制电动伸缩杆的顶杆伸出，直至滚轮座压紧在压环上，并且第一摩擦环压紧第二摩擦环，稳定了滚柱在柱槽内的状态，操作换向阀，使得液压缸的顶杆缩回，压板失去对旋轴的抵压，此时在牵引车牵引下，压辊得以在级配粗石层上滚压，因此实现两种模式的转换，适应程度高。
