Abstract
A system assisting a monorail excursion train in going uphill comprises a jacking wheel (2) and a jacking wheel holder (3). The jacking wheel (2) is located below a rail top plate (1) and can roll by pressing a bottom face (11) of the rail top plate in the running process of a train. The jacking wheel holder (3) is used for mounting and bearing the jacking wheel. A pressing device (5) is connected between the jacking wheel holder and a steering framework (4) and can adjust the positive pressure between the jacking wheel and the bottom face of the rail top plate. By means of the jacking wheel, the positive pressure between the train and a rail can be increased under the situation that the weight of the train is not increased, accordingly, the wheel-rail adhesion is increased, and the gradeability of the train is improved, specifically, experiments prove that the gradeability can be improved to 14% from 8%. The system assisting the monorail excursion train in going uphill can automatically judge the wheelslip situation and automatically start the pressing device to assist in going uphill according to the wheelslip situation; and when the train totally passes through a slipped slope, the pressing device can reset automatically, and the situation that after the pressing device operates for a long time, extra loads are caused to the train is avoided.
