The invention belongs to the technical field of coal mine underground auxiliary trackless transport, and particularly relates to a hinging wheel type coal mining machine carrying vehicle, which solves the problems that the size of a coal mining machine is large, and a machine body is long, so the loading and the unloading are difficult, potential safety hazards exist in transport, and the damage to roadway pavements is serious. The hinging wheel type coal mining machine carrying vehicle is characterized in that a towing vehicle assembly is connected with a trailer assembly through a middle hinging assembly and a middle hinging shaft; the trailer assembly comprises a U-shaped structure formed by connecting a left support leg, a support seat hinging assembly and a right support leg; the support seat hinging assembly is of a telescopic and fixable structure; telescopic auxiliary support mechanisms are respectively and vertically arranged in positions, near a tire assembly, on the left support leg and the right support leg; and a front lifting mechanism and a back lifting mechanism are respectively arranged at the front end and the back end of the left support leg and the right support leg. The hinging wheel type coal mining machine carrying vehicle has the beneficial effects that external power is not needed; the self assembling and the self disassembling of the coal mining machine can be realized; safety and reliability are achieved; the grounding pressure is small; the roadway pavements are not damaged; and the moving efficiency and the safety of fully mechanized coal faces in a coal mine are greatly improved.
