Abstract
The utility model discloses a partial-tension high-elasticity compensating contact net which belongs to the technical field of a compensating contact net fitting of an electrified railway and is mainly characterized in that: the partial-tension high-elasticity compensating contact net comprises a Z-shaped contact line along the railway direction, a vertical tension compensating mechanism along the line direction, and a wrist arm pipe provided with a positioner and a positioning pipe; and a transverse tension compensating mechanism connected with the contact line is arranged in the direction vertical to the line direction. When the contact line is tensioned or loosened due to such reasons as expansion, contraction, wind swinging and the like, the transverse tension compensating mechanism carries out tension tracking compensation on the contact line at the same time as a dropping weight is utilized to carry out tensioning; compensating tensions at the two ends of the contact line are uniformly distributed onto the elastic positioner between spans, so as to lead an elastic mechanism of each elastic positioner to generate a lateral tension on the contact line, thereby improving the problem of non-uniform tension distribution between the spans and optimizing the tension distribution of an entire contact net system; therefore, the entire contact net system has higher elasticity, the lowering condition of tension degree is improved, and the contact net can effectively restrain the wind swinging and resonance.
Description
Technical field
The utility model belongs to electrified railway compensation contact system technical field, relates in particular to a kind of minute tension force high resiliency compensation contact system.
Background technology
In recent years China's electrified railway develop rapidly, the electric locomotive of high-speed cruising requires more and more higher to the safe reliability of overhead current collection.Present stage, China's contact system mainly adopted the stone roller gravity compensation mode of weighing down, make and reach certain force of strain on the contact wire, and it is longer in the practical application owing to the anchor section, separately to the both sides longitudinal extension, dropper and steady arm produce displacement, each dropper and steady arm all have a pulling force to the line case, compensate the Tension Difference between casting anchor to terminal so cause the mid point anchor place.Make contact wire tension force decay gradually to the mid point anchor place from the end that casts anchor, because the decay of middle part tension force, elasticity variation, the stability that flowed of contact wire descends to some extent, what bring is that wind resistance pendulum and association's shake ability weaken thereupon, for the elasticity that improves the middle part, the contact pressure that guarantees bow net, have only the bob stone roller weight that increases two ends, and soft two ends are hard in the middle of so still being.Have higher requirement also for simultaneously each parts intensity of contact system, increased manufacturing cost virtually, also buried hidden danger for the long-term safety operation.Many problems such as material and processing technology make whole contact net system be faced with acid test in addition.
