The invention discloses a bow piece tensioning lifting arm. The bow piece tensioning lifting arm comprises a vehicle body, a left bow piece and a tail end. The bottom end of the left bow piece is rotationally connected to the vehicle body, and the top end is fixedly connected to the tail end; the left bow piece comprises a plurality of bow pieces which are sequentially and rotatably connected, driving mechanisms which are in one-to-one correspondence with the bow pieces, and tensioning mechanisms; the driving mechanisms are used for driving the corresponding bow pieces to rise and retract; the tensioning mechanism is used for crosswise locking at least one bow piece in a lifting state, so that the bow piece is tensioned to form an arch-shaped stable structure; the bow pieces are made of carbon fibers. According to the bow slice tensioning elevating arm, the purposes of light weight, stability, low energy consumption and easy maintenance are achieved, the carbon fiber material is adopted, excellent elasticity and tensile performance are achieved, the self weight is reduced, and the structural strength and reliability are improved.
本发明公开了一种弓片张拉举高臂,该弓片张拉举高臂包括车体、左部弓片以及末端;左部弓片的底端转动连接于车体,顶端固定连接于末端;左部弓片包括依次转动连接的多节弓片、与每节弓片一一对应的驱动机构以及张拉机构;驱动机构用于驱动对应的弓片升起和收起;张拉机构用于交叉锁紧处于升起状态的至少一个弓片,使弓片张拉形成弓形稳定结构;弓片采用碳纤维制成。上述弓片张拉举高臂实现了轻量化、稳定性、低能耗和易维护的目标,采用碳纤维材料具有出色的弹性和抗拉性能,不仅减轻了自重,还提升了结构强度和可靠性。
