The invention relates to a transport trolley, in particular to a thin coal seam fully-mechanized coal mining accessory transport vehicle. The work space of a thin coal seam fully-mechanized coal mining working surface is generally small, the work space for workers is also very small, equipment matching is compact as well, and therefore accessories can not be transported conveniently when equipment is overhauled. High labor intensity needs to be borne by the workers, and due to the fact that a large number of personnel are needed, large potential hazards exist in terms of safety. The thin coal seam fully-mechanized coal mining accessory transport vehicle comprises wheels, a frame, a compartment and a brake, and is characterized in that the wheel distance of the wheels is the same as the distance between baffles on the two sides of a scraper conveyer, a flange is arranged inside each wheel, and the flanges are clamped inside the baffles of the scraper conveyer. The thin coal seam fully-mechanized coal mining accessory transport vehicle is simple in structure, convenient to use, flexible, good in safety, widely suitable for transportation of accessories, tools and materials in underground shafts with narrow work space and underground tunnels with narrow work space in the industrial and mining industries.
