The invention relates to an active driving type folding and unfolding supporting device, a movable contact net and an operation method. The active driving type folding and unfolding supporting device comprises stand columns, a folding and unfolding supporting mechanism, a moving mechanism and a driving mechanism, the moving mechanism can move in the length direction of the stand columns, and the driving mechanism is used for driving the moving mechanism to move in the length direction of the stand columns; the moving mechanism moves to drive the folding and unfolding supporting mechanism to stretch or retract, so that the free end of the folding and unfolding supporting mechanism drives a contact line and/or a carrier cable to move to a working position or a non-working position or switch between the working position and the non-working position. The situation that bending points exist in the prior art can be effectively avoided, and the technical defect that an arc line appears in the prior art is overcome; on the other hand, each stand column in the whole mobile overhead line system adopts an active driving type folding and unfolding supporting device, and the conditions that in the prior art, pulling cannot be carried out, and a telescopic mechanism cannot be unfolded in place are avoided.
本发明涉及主动驱动式收放支持装置、移动接触网及操作方法,包括立柱、收放支持机构、移动机构和驱动机构,所述移动机构能够沿立柱的长度方向移动,所述驱动机构用于驱动移动机构沿立柱的长度方向移动,所述移动机构移动带动收放支持机构伸展或者收缩,以使所述收放支持机构的自由端带动接触线和/或承力索移动到工作位、非工作位或者在工作位与非工作位之间切换。本发明能够有效的避免现有技术存在折弯点情况,避免了现有技术中出现弧线的技术缺陷;另一方面整个移动接触网中每一个立柱上均采用主动驱动式收放支持装置,避免了现有技术中出现拉不动,伸缩机构展不开不到位的情况。
