The invention belongs to the technical field of tunnel excavation supporting, and particularly relates to self-moving type advance supporting equipment of a heading machine. During supporting, two bottom supporting structures are located on the ground, and a front end supporting structure is driven by a first connecting mechanism to form advance supporting in a tunnel; the second connecting mechanism drives the rear end supporting structure to support the tunnel; along with tunneling of the tunnel, the front bottom supporting structure is relatively fixed, the fourth telescopic rod retracts to drive the rear bottom supporting structure to move forwards, the rear bottom supporting structure is relatively fixed, and the fourth telescopic rod extends to drive the front bottom supporting structure to move forwards; therefore, the forepoling equipment moves forwards along with tunneling of the tunnel, the labor intensity of workers is reduced, the tunneling efficiency is improved, and potential safety hazards are reduced.
本发明属于隧道挖掘支护技术领域,尤其涉及一种掘进机自移式超前支护设备,本发明中,在进行支护时,两底部支撑结构位于地面上,通过第一连接机构带动前端支护结构在隧道内形成超前支护,第二连接机构带动后端支护结构对隧道进行支护;随着隧道的掘进,位于前方的底部支撑结构相对固定,第四伸缩杆收缩带动位于后方的底部支撑结构前移,位于后方的底部支撑结构相对固定,第四伸缩杆伸长带动位于前方的底部支撑结构前移,如此往复,从而使得本发明的超前支护设备随着隧道的掘进前移,减少人工劳动强度,提高掘进效率,降低安全隐患。
