The invention discloses a co-cavity supporting leg structure and a tunneling drill carriage, the co-cavity supporting leg structure comprises a fixed supporting leg, a cavity is arranged in the fixed supporting leg, the two ends of the fixed supporting leg are fixedly connected with force bearing plates, one side of each force bearing plate is provided with a sliding through hole, the other side of each force bearing plate is provided with a mounting through hole, and a movable supporting leg assembly is slidably connected in the cavity; one end of the movable supporting leg assembly penetrates through the sliding through hole and is fixedly connected with an oil cylinder base, the other end of the movable supporting leg assembly penetrates through the installation through hole of the other force bearing plate and is fixedly connected to the force bearing plate through an installation base, the outer cross section of the movable supporting leg assembly is polygonal, and a plurality of wedge blocks are fixedly connected into the cavity. The multiple wedge-shaped blocks are arranged on the side edge of the movable supporting leg assembly at intervals, the multiple sets of wedge-shaped blocks make contact with the movable supporting leg assembly and slide, and the common-cavity supporting leg structure is applied to the tunneling drill carriage. The device has the advantages that the structure is simple, and maintenance is convenient; the height of the supporting legs is reduced, and interference to an upper drill boom of the tunneling drill carriage is avoided; the stress is improved, and the durability is prolonged.
本发明公开了一种共腔支腿结构和掘进钻车,共腔支腿结构包括固定支腿,固定支腿内设有腔体,其两端固定连接有承力板,承力板的一侧设有滑动通孔,另一侧设有安装通孔,腔体内滑动连接有活动支腿组件,活动支腿组件的一端穿过滑动通孔并固定连接有油缸座,其另一端穿过另一承力板的安装通孔并通过安装座固定连接到承力板上,活动支腿组件的外部横截面呈多边形,腔体内固定连接有多组楔形块,多个楔形块间隔布置在活动支腿组件的侧边,多组楔形块与活动支腿组件接触并滑动,掘进钻车应用有上述共腔支腿结构。本发明的优点在于:结构简单便于维护;降低支腿高度,避免对掘进钻车的上部钻臂造成干涉;改善受力,延长其耐久度。
