Multi-section carbon fiber fire-fighting extension ladder
The invention relates to a multi-section carbon fiber fire-fighting extension ladder. The multi-section carbon fiber fire-fighting extension ladder comprises a plurality of ladder pieces, wherein theplurality of ladder pieces are mutually stacked; the ladder pieces include a bottom ladder piece and at least one drawing ladder piece; a self-locking mechanism is arranged between every two adjacentladder pieces; side rods are hollow rod bodies made of section bars, upward convex slideways are formed in the tops of the side rods, inward concave slideways are formed in the bottoms of the side rods, and side chutes are formed in outer side edges; a lower connecting assembly and an upper connecting assembly are arranged on the extension ladder; the lower connecting assembly comprises a bottom guide assembly which is used between the bottom ladder piece and the drawing ladder piece connected with the bottom ladder piece and a first middle guide assembly which is used between the adjacent drawing ladder pieces; and the upper connecting assembly comprises a top guide assembly which is used between a top drawing ladder piece and the adjacent ladder piece and a second middle guide assembly which is used between the ladder pieces except the top drawing ladder piece. According to the multi-section carbon fiber fire-fighting extension ladder, the ladder pieces are telescopically matched through the corresponding guide mechanisms, and the force of friction between the ladder pieces is reduced; and the multi-section carbon fiber fire-fighting extension ladder has the advantages of the stable and safe structure, high structural stability, difficulty in deformation and long service life.
一种多节式碳纤维消防拉梯，包括相互层叠的若干梯片；梯片包括一个底层梯片和至少一个抽拉梯片；在相邻的梯片之间设有自锁机构；侧杆为型材构成的中空杆体，其顶部设有上凸滑道，底部设有内凹滑道，外侧边设有侧滑槽；拉梯设有下连接组件和上连接组件；下连接组件包括用于底层梯片和与其相连的抽拉梯片之间的底层导向总成以及用于相邻抽拉梯片之间的第一中间导向总成；上连接组件包括用于顶层抽拉梯片和与其相邻梯片之间的顶层导向总成以及用于除顶层抽拉梯片之外的梯片之间的第二中间导向总成；本发明每层梯片之间通过对应的导向机构实现伸缩配合，保证梯片之间减少摩擦力；整体结构稳定、安全，拉梯结构稳定性更好，不易变形，使用寿命更长。
