The invention relates to a wide and narrow tracked vehicle, which belongs to the technical field of coal mine drilling rigs and comprises a frame body, the frame body comprises a wide rear section and a narrow front section, the rear section and the front section are respectively used for supporting a power assembly and a drilling device, and a guide groove is further formed in the middle of the upper side of the front section and is used for butting and guiding the drilling device; main track assemblies with the length matched with that of the frame body are arranged on the two sides of the frame body, and at least one set of anti-overturning wheels or at least one set of auxiliary track assemblies are arranged at the positions, corresponding to the rear sections, of the outer sides of the main track assemblies. The structure with the narrow front portion and the wide rear portion is adopted, the requirement for contact specific pressure of the crawler is met, meanwhile, the anti-overturning requirement is met, the space of the crawler is saved, the volume ratio of the crawler to the whole machine can be reduced, space can be provided for embedding integration of other devices, and development and application of an underground drilling machine are facilitated.

    本发明涉及一种宽窄体履带车,属于煤矿钻机技术领域,包括车架体,车架体包括呈宽体的后段和呈窄体的前段,后段和前段分别用于动力组件和钻进装置的支撑,前段的上侧中部还开设有导向槽以用于钻进装置的对接导向;车架体的两侧设有长度与车架体长度匹配的主履带组件,主履带组件的外侧对应后段的位置设有至少一组抗倾覆轮或至少一组副履带组件。本发明采用前窄后宽的结构,既满足了履带车接触比压的要求,同时也满足了抗倾覆要求,节省了履带车空间,进而可使履带车占整机的体积比缩小,因此还能够为其它装置的嵌入集成提供空间,利于井下钻机的发展应用。
