Cantilever heading machine
The invention relates to the technical field of tunnel construction, in particular to a cantilever tunneling machine. The cantilever tunneling machine comprises a tunneling machine body, a cutting arm and a main slag removal device are arranged on the front portion of the tunneling machine body, the main slag removal device is located below the cutting arm, a cutting head is arranged on the cutting arm, the cantilever tunneling machine further comprises an auxiliary slag removal device, and the auxiliary slag removal device comprises a mechanical arm and a slag skimming device connected to the tail end of the mechanical arm; when the mechanical arm is in the unfolded state, the slag removing device is located in front of the main slag removing device so as to remove slag at the bottom corner of the tunnel into the main slag removing device; when the mechanical arm is in the folded state, the slagging-off device is located behind the cutting head so as to avoid the section when the section is broken by the cutting head. By means of the design, when a small-section tunnel is constructed, the muck can be completely cleaned without retreating a machine, the follow-up beam erecting and arch erecting operation is prevented from being affected, and the overall construction efficiency of the tunnel is improved.
本发明涉及隧道施工技术领域，具体涉及一种悬臂掘进机。悬臂掘进机包括掘进机主体，掘进机主体的前部设有截割臂和主清渣装置，主清渣装置处于截割臂的下方，截割臂上设有截割头，悬臂掘进机还包括辅助清渣装置，辅助清渣装置包括机械臂和连接在机械臂末端的扒渣装置；在机械臂处于展开状态时，扒渣装置处于主清渣装置的前方以将隧道底角处的渣土扒入主清渣装置内；在机械臂处于收合状态时，扒渣装置处于截割头的后方以在截割头破碎断面时避让断面。这样设计，在小断面隧洞施工时，无需退机，即可将渣土完全清理，避免影响后续架梁立拱作业，提升隧道整体施工效率。
