Tensioning-free passive cable traction vehicle

Technical Field

The invention belongs to the field of endless rope winches and mountain rail cars, and particularly relates to a tensioning-free passive traction car.

Background

Along with the land demand of industrial and economic development and the reality of most of seven mountains, one water and two half fields in south China in the south of the Yangtze river, people constantly pay attention to the fact that the soil layer is thick and the soil quality is good, and the land is suitable for hilly areas where economic fruit trees are planted.

The mining endless rope winch is a common reciprocating type index transport tool used in mines, has large load capacity and low facility investment, but has large terrain adaptation limitation, and is not suitable for curves or slopes with the gradient larger than 9 degrees; in addition, the mountain rail car is a transportation tool for solving the problem of hilly orchard transportation recently, and bears the rail car through a single rail or two welded rails, so that the problem of higher infrastructure cost exists, and particularly the problem that the single-rail transportation car is small in load capacity and easy to overturn and damage the rails due to partial loading is also caused.

The existing cableway can only realize point-to-point transportation, and meanwhile, if the load capacity needs to be increased, the investment of a line bracket is greatly increased.

The tension-free active traction vehicle solves the problem of long-distance transportation, but because power and a guiding device need to be installed on the vehicle, the effective load of the vehicle is reduced, and meanwhile, the tension-free active traction vehicle can only be used for single-vehicle transportation and cannot effectively utilize kinetic energy generated when the vehicle goes downhill.
