[0002] The rolling of slope cushion materials is a key link in the construction of the reservoir bank of a pumped storage power station and other earth-rock dams. The construction quality directly affects the construction quality of the reservoir anti-seepage panel. At present, the commonly used rolling equipment includes rollers and vehicle-mounted rolling tractors. Single rollers are mostly used for rolling on the ground or on smaller slopes. The rolling of the rolling wheels is driven by the vehicle body, which has good effects in steering and rolling, but is not suitable for slopes with larger slopes. The commonly used equipment on slopes is slope rolling equipment. The tractor is above the slope and uses a winch to drive the traction rope, which pulls the roller upward. The tractor using slope rolling equipment cannot guarantee the rolling direction and is prone to deviation. It is also difficult to control the steering of the roller. The steering time is long, which prolongs the construction period and wastes time. In addition, the tractor above the slope is easily driven and slides down the slope. Therefore, a rolling equipment with controllable roller steering and strong tractor stability is needed. Summary of the invention
