Abstract
The invention relates to the construction, in particular to devices for leveling and compaction of road surfaces.The device, according to the 1st and 2nd variants, contains mounted with the possibility of rotation on the frame a drive vertical shaft (1). At the lower end of the shaft (1) in two tiers are fixed two groups of cantilevers (2, 3) radially oriented in the horizontal direction, each pair of overlapped cantilevers is joined with a power drive in the form of hydraulic cylinder (4). The cantilevers (2) of the upper tier are rigidly fixed on the shaft (1), and the cantilevers (3) of the lower tiers are fixed on the shaft (1) by means of a hinge with horizontal axis. The hydraulic cylinders (4) in the operating mode of the device are made in the form of hydraulic mechanisms for reloading of sealing elements. Each cantilever (3) of the lower tier may be connected to the adjacent cantilevers (3) of this tier, which are rigidly fixed by torsion bars.In the device, according to the 1st variant, the cantilevers (3) are made with the possibility of changing the length, and at their free ends are mounted balance frames (5), on each frame are fixed the axles (6) of the sealing elements, made in the form of a set of cylindrical rollers (7) of the same diameter and installed on the axle (6) with the possibility of an independent free rotation.In the device, according to the 2nd variant, on the free ends of each cantilever of the lower tier is rigidly fixed an axle, on which with the possibility of free rotation is installed a sealing element in the form of a truncated cone, the smaller base of which is placed on the part of the shaft (1).The device may contain conical completion rollers, rigidly fixed between each other and to the sealing element.The oriented outside end faces of the sealing elements in the device, according to both variants, may be made curved outward in the direction of the axle.<SDOAD>
