The invention discloses an all-wheel steering composite linkage mechanism, relates to the technical field of mine mechanical equipment, and solves the technical problems of steering failure and tire slippage easily caused by a traditional hydraulic support carrier. All wheels comprise front-end and rear-end wheels, the composite linkage mechanism comprises a steering gear, power cylinders, joint pieces and connecting pieces, each joint piece is fixed to a suspension of the corresponding wheel, each power cylinder is hinged to the corresponding joint piece, the steering gear is communicated with the multiple power cylinders through pipelines, and the connecting pieces are hinged between the joint pieces of the front-end wheel; the steering gear drives the front-end and rear-end wheels to rotate cooperatively through the plurality of power cylinders, and the connecting pieces drive the front-end wheels at the two sides of the vehicle to rotate cooperatively. According to the invention, the problem of steering failure caused by small adhesive force of tires is avoided, the problem of tire slippage is also avoided, the service life of the tires is prolonged, the front-end wheels and the rear-end wheels rotate cooperatively, and the trafficability of the whole vehicle in an underground roadway of a coal mine is also improved.

    本发明公开了一种全轮转向的复合联动机构,涉及矿井机械设备技术领域,解决了传统液压支架搬运车容易引起的转向失效以及轮胎滑移的技术问题。全轮包括前端车轮与后端车轮,复合联动机构包括转向器、动力缸、关节件以及连接件,每个关节件与车轮的悬架固定,每个动力缸与每个关节件铰接,转向器通过管路与若干动力缸连通,连接件铰接于前端车轮的关节件之间;转向器通过若干动力缸分别驱动前端车轮与后端车轮协同转动,连接件带动车辆两侧前端车轮协同转动。本发明不仅避免了由于轮胎附着力小而导致的转向失效的问题,而且避免了轮胎滑移的问题,提高了轮胎的使用寿命,前端车轮与后端车轮协同转动,还提高了整车在煤矿井下巷道内的通过性。
