Abstract
The invention provides a telescopic rail type lateral stress steering suspension rail traveling device and belongs to the technical field of rail transporting machines. The telescopic rail type lateral stress steering suspension rail traveling device uses telescopic rail type lateral drive auxiliary steering devices for solving the problem that a lower suspension traffic rail cannot achieve quick and stable rail changing and reversing. A rail bottom suspension drive device uses pressure transmission arms for converting the weight of a suspended object into pressure jacking drive wheels upwards. The pressure of the drive wheels is automatically adjusted according to the weight of the suspended object. The power consumption of a differential motor is reduced. The telescopic rail type lateral drive auxiliary steering devices serve as auxiliary power so that the kinetic energy of the suspension rail traveling device can be greatly improved. An intra-rail sliding body and the rail bottom suspension drive device are combined, the structural distribution is more reasonable, and lower suspension rail traffic facilities run more stably and safely.
