ROAD BED FORMING DEVICE Russian patent published in 2022 - IPC E01C19/00 

FIELD: construction.

SUBSTANCE: invention relates to road bed forming devices. Posts connect the upper frame with the lower frame. Two satellite antennas, three left and three right posts are attached to the upper frame from above, platforms, six boards and paths are welded. Drums for hydraulic pump drive are also installed on the upper frame. Six links are pivoted to the lower frame. Three frames of entrances are attached to links. Drivers are pivotally attached to the lower frame from below. Running gear rollers are installed on axes of bars. Between the upper frame and the lower frame there are two cisterns with electrically controlled cranes, a small crushed stone bin, a large crushed stone bin and two sand bins. Smoothing bars are welded to coarse gravel bin and sand bins from below. Between the small crushed stone bunker, the large crushed stone bins and the sand bins there are rollers with a drive from the rollers drive hydraulic motors. Hydraulic cylinders of rollers control are connected to posts. Plates are attached to hydraulic hammers from below. On the lower frame there is a hydraulic accumulator. Hydraulic accumulator comprises two springs, two pistons and shock absorbers. Hydraulic accumulator is connected to: a supply pipe, a flow pipe, a filling sensor and an emergency discharge pipe. Near the hydraulic accumulator there are: a receiver, a compressor, a generator, a drive hydraulic motor, a receiver of primary brake release. Receiver is interconnected with tanks, reservoirs for storage of hydraulic working fluid and with drum brakes. Hydro-pneumatic cylinders are attached to the lower frame traverse and to the entry frames.

EFFECT: higher efficiency and quality.
