The invention relates to the technical field of heading machines, and discloses a traveling mechanism with traveling and supporting functions, which comprises a track frame, the track frame comprises a cross beam extending front and back, a mounting plate is arranged on the side surface of the cross beam and used for being connected with an equipment rack body, and a track chain is arranged on the periphery of the track frame. The front end and the rear end of the crawler frame are provided with a guide wheel and a driving unit meshed with the crawler chain respectively, thrust wheels are arranged below the crawler frame, a sliding shoe supporting plate and a telescopic mechanism are arranged below the crawler frame, and the walking state and the supporting state are switched through the telescopic mechanism. In the walking state, the thrust wheel makes contact with the crawler chain, and the sliding shoe supporting plate makes contact with the crawler chain. In the supporting state, the thrust wheel makes contact with the crawler chain, and the sliding shoe supporting plate makes contact with the crawler chain. The track supporting device has a walking form and a supporting form, the thrust wheels make contact with a track chain during walking to reduce walking friction, the sliding shoe supporting plates make contact with the track chain during supporting to resist supporting force, and damage to the thrust wheels during supporting is effectively avoided.
本发明涉及掘进机技术领域,公开了一种兼具行走与支撑的行走机构,包括履带架,履带架包括前后延伸设置的横梁,横梁侧面设置有安装板,用于与设备机架本体连接,履带架外周设置有履带链,履带架的前后端分别设置有导向轮和与履带链啮合的驱动单元,履带架的下方设置有支重轮,其中,履带架的下方设置有滑靴支撑板和伸缩机构,通过伸缩机构切换行走和支撑状态,行走状态时支重轮接触履带链而滑靴支撑板与履带链脱离接触,支撑状态时支重轮与履带链脱离接触而滑靴支撑板接触履带链。本发明具有行走和支撑两种形态,行走时支重轮与履带链接触减小行走摩擦,支撑时采用滑靴支撑板与履带链接触来抵抗支撑力,有效避免了支撑时对支重轮造成的损坏。
