The invention relates to an active drive type folding and unfolding support device, a mobile contact net and an operation method. The device comprises a stand column, a support mechanism, a moving mechanism, a connecting piece, a motor and a chain; the moving mechanism can move in the length direction of the stand column, one end of the connecting piece is directly or indirectly connected with the stand column, and the other end of the connecting piece is connected with the support mechanism; one end of the supporting mechanism is movably connected with the moving mechanism; the motor drives the chain to rotate to drive the moving mechanism to move, so the free end of the supporting mechanism drives the contact line and/or the carrier cable to move to a working position or a non-working position or to be switched between the working position and the non-working position. According to the invention, the situation of bending points in the prior art can be effectively avoided, and the technical defect of arcs in the prior art is avoided; on the other hand, each stand column in the whole mobile contact network is provided with an active driving type folding and unfolding supporting device, and the situations that in the prior art, pulling cannot be conducted, 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、支持机构、移动机构、连接件、电机和链条,移动机构能够沿立柱的长度方向移动,连接件的一端直接或者间接的与立柱连接,连接件的另一端与支持机构连接;所述支持机构一端与所述移动机构活动连接;所述电机驱动链条转动带动所述移动机构移动,以使所述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两者之间切换。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。
