Transport system for steep-slope tunnel

The invention discloses a transport system for a steep-slope tunnel. The transport system comprises a traction unit composed of a rubber-tyred tractor truck, a rail-mounted transport vehicle and a road surface in the tunnel. The road surface in the tunnel comprises a track and a walking road surface which is arranged outside of the track and is flush with the track. The rubber-tyred tractor truck comprises an axle, a truck frame, a parking system and a driving system. Wheels at two ends of the axle are arranged to be solid rubber tyre wheels corresponding to the walking pavement and the track. Guiding wheels corresponding to the track are arranged on the truck frame and are located in front of and / or behind the solid rubber tyre wheels for guiding the solid rubber tyre wheels by cooperation with the track. A rubber-tyred vehicle with static pressure transmission is utilized for a gilled tube vehicle, a motor truck, a material car and marshalling vehicles for rail-bound construction on a large-slope branch tunnel (an inclined shaft). The cooperation among the track and the guide wheels is used for steering so that operation is simplified.
