The invention provides a lifting driving shed and a heading machine, and relates to the technical field of heading machines. The multiple stand columns are arranged at intervals, the first ends of the stand columns are connected with the ceiling, and the second ends of the stand columns are connected with the heading machine body; the stand column comprises a telescopic outer barrel, a telescopic inner barrel and a lifting oil cylinder, the telescopic outer barrel is fixedly connected with the heading machine body, one end of the telescopic inner barrel is connected with the ceiling, the other end of the telescopic inner barrel is inserted into the telescopic outer barrel and slidably connected with the telescopic outer barrel, and the two ends of the lifting oil cylinder are connected with the telescopic inner barrel and the telescopic outer barrel respectively; the telescopic outer cylinder comprises four side plates which are sequentially connected, friction plates are arranged on the four side plates respectively, and the inner surfaces of the friction plates make contact with the outer surface of the telescopic inner cylinder. According to the technical scheme, in the up-down sliding process of the telescopic inner barrel, the friction force in the lifting process of the driving shed is reduced, the selection specification of the oil cylinder is reduced, and the machining area of the inner surface of the telescopic outer barrel is also reduced.
本申请提出了一种升降驾驶棚和掘进机,涉及掘进机技术领域,升降驾驶棚包括:顶棚;多个立柱,多个立柱间隔设置,立柱的第一端与顶棚相连,立柱的第二端与掘进机本体相连;立柱包括伸缩外筒、伸缩内筒和升降油缸,伸缩外筒与掘进机本体固定连接,伸缩内筒的一端与顶棚相连,另一端插设在伸缩外筒内,与伸缩外筒可滑动地连接,升降油缸的两端分别与伸缩内筒、伸缩外筒相连;伸缩外筒包括四个侧板,四个侧板依次连接,四个侧板上分别设有摩擦板,摩擦板的内表面与伸缩内筒的外表面相接触。通过本申请的技术方案,在伸缩内筒上下滑动过程中,减少了驾驶棚升降过程中的摩擦力,降低了油缸选用规格,也减少了伸缩外筒内表面的加工面积。
