The invention relates to the technical field of coal mine operation, in particular to a carrying vehicle for carrying a multi-loop combination switch for an underground coal mine in a workshop. The carrying vehicle comprises a frame supporting trolley and a handheld bearing roller supporting pull rod. The frame supporting trolley comprises a supporting frame, two long metal supporting legs are fixedly connected to one side of the supporting frame, two short metal supporting legs are fixedly connected to the other side of the supporting frame, the lower ends of the two short metal supporting legs are jointly and fixedly connected with a bearing roller shaft I, and the two ends of the bearing roller shaft are sleeved with bearing type bearing rollers I respectively. A guide traction groove is fixed on the reinforcing beam. The handheld bearing roller supporting pull rod comprises a bearing roller shaft II, the two ends of the bearing roller shaft II are sleeved with bearing type bearing rollers II respectively, a supporting rod perpendicular to the bearing roller shaft II is welded to the middle of the bearing roller shaft II, and a guiding traction shaft head is further fixedly connected to the connecting position of the supporting rod and the bearing roller shaft II. The carrying vehicle is simple in structure, labor-saving, convenient and fast to operate and low in manufacturing cost; and the labor intensity is reduced. Furthermore high safety and high efficiency are realized.

    本发明涉及煤矿作业技术领域,具体涉及一种用于车间搬运煤矿井下用多回路组合开关的搬运车;包括框架支撑小车和手持承重滚轮支撑拉杆;所述框架支撑小车包括支撑框架,支撑框架的一侧固接有两根长金属支撑腿,另一侧固接有两根短金属支撑腿,两根短金属支撑腿的下端共同固接有一根承重滚轮轴Ⅰ,所述承重滚轮轴的两端分别套设有承重型轴承滚轮Ⅰ,加强梁上固定有导向牵引槽;手持承重滚轮支撑拉杆包括一根承重滚轮轴Ⅱ,承重滚轮轴Ⅱ的两端分别套设有承重型轴承滚轮Ⅱ,承重滚轮轴Ⅱ的中部焊接有与其垂直的支撑杆,支撑杆与承重滚轮轴Ⅱ的连接处还固接有导向牵引轴头;本发明结构简单、节省人力、操作方便快捷、制作成本低;降低劳动强度,安全高效。
