The invention discloses an inverted siphon tunnel automatic folding and unfolding maintenance trolley which comprises an anchoring support corresponding to an inverted siphon tunnel maintenance door groove and a bearing flat car rotationally matched with the anchoring support. The anchoring support comprises a support body, and the support body is provided with a hoisting mechanism used for collecting and releasing the bearing flat car, a rotating mechanism used for folding the bearing flat car and a locking mechanism used for locking the bearing flat car. During working, the locking mechanism loosens the bearing flat car, and the hoisting mechanism hoists the bearing flat car from a folded state to an unfolded state through the rotating mechanism; during folding, the hoisting mechanism withdraws the bearing flat car, so that the bearing flat car is folded on the anchoring support through the rotating mechanism, and the locking mechanism locks the bearing flat car. Through cooperation of the anchoring support and the bearing flat car, material transportation work in the tunnel and overhaul and maintenance work of the tunnel are facilitated, the tunnel construction efficiency is improved, and the technical problem that an existing overhaul trolley cannot be suitable for the inverted siphon tunnel is effectively solved.
一种倒虹吸隧洞自动收放检修台车,包括对应于倒虹吸隧洞检修门槽的锚定支座和与锚定支座旋转配合的承载平板车;锚定支座包括支座体,支座体上设置有用于收放承载平板车的吊装机构、用于折叠承载平板车的旋转机构和用于锁定承载平板车的锁定机构;工作时,锁定机构松开承载平板车,吊装机构将承载平板车通过旋转机构从折叠状态吊装至展开状态;折叠时,吊装机构将承载平板车收回,使承载平板车通过旋转机构折叠于锚定支座上,锁定机构对承载平板车进行锁定。本发明通过锚定支座和承载平板车的配合便于隧洞内的材料运输工作和隧洞的检修维护工作,提高了隧洞施工效率,有效地解决了现有检修台车无法适用于倒虹吸隧洞的技术问题。
