The invention provides a self-driven inhaul cable type track structure suitable for a large ramp in a mountainous area, and relates to the technical field of track traffic, the self-driven inhaul cable type track structure comprises sleepers and steel rails above the sleepers; an inhaul cable extending in the length direction of the steel rail is arranged below the bogie; a gear transmission device is connected to the lower portion of the bogie, and the inhaul cable is connected to the gear transmission device in a wound mode. The inhaul cable is static relative to the steel rail, and the length of the inhaul cable wound on the gear transmission device is kept unchanged in the moving process, so that the inhaul cable keeps traction force and braking force on operation of the bogie. The rail structure has the beneficial effects that the inhaul cable is adopted to replace a rack structure and a rack fastener of a traditional rack rail railway, the vehicle wheel shaft rotates to drive the winding inhaul cable to generate traction force and braking force, meanwhile, the longitudinal and transverse resistance of the rail structure is enhanced through the fixing device, the construction cost can be reduced, seamless performance of the rail structure can be guaranteed, and the service life of the rail structure is prolonged. The adaptability of the track and the lower foundation is enhanced, and the running stability of a train is improved.
本发明提供一种适用于山区大坡道的自驱动拉索式轨道结构,涉及轨道交通技术领域,包括轨枕以及轨枕上方的钢轨;转向架的下方设置有沿钢轨的长度方向延伸的拉索;转向架的下方连接有齿轮传动装置,拉索缠绕连接在齿轮传动装置上;拉索相对钢轨静止,并且在移动过程中拉索缠绕在齿轮传动装置上的长度保持不变,从而令拉索对转向架的运行保持有牵引力以及制动力。本发明的有益之处是,采用拉索取代传统齿轨铁路的齿条结构和齿条扣件,并采用车辆轮轴转动驱动缠绕拉索产生牵引力和制动力,同时通固定装置增强轨道结构的纵横向阻力,既能降低工程造价,又能保证轨道结构的无缝化,增强轨道与下部基础的适应性,提升列车运行的平稳性。
