The invention provides a coal mine transporting machine. The coal mine transporting machine comprises a support A (1) and a support B (1). The support A (1) is provided with a fixing gear A (3) and a fixing gear B (4). The support B (2) is provided with a fixing gear C (5) and a fixing gear D (6). A hanging plate (7) is arranged between the support A (1) and the support B (2). A rotating shaft A (8) is arranged at one end of the hanging plate (7), and a rotating shaft B (9) is arranged at the other end of the rotating hanging plate (7). A large gear A (10) is arranged on the rotating shaft A (8), and a small gear A (11) and a small gear B (12) are arranged at the two ends of the rotating shaft A (8) respectively. The small gear A (11) is meshed with the fixing gear A (3), and the small gear B (12) is meshed with the fixing gear C (5). A large gear B (13) is arranged on the rotating shaft B (9). A small gear C (14) and a small gear D (15) are arranged at the two ends of the rotating shaft B (9) respectively. The small gear C (14) meshes with the fixing gear B (4). The small gear D (15) is meshed with the fixing gear D (6). A gear (17) is arranged on an output shaft of a motor (16) arranged in the middle portion of the hanging plate (7), and the large gear A (10) and the large gear B (13) are meshed with the gear (17). The coal mine transporting machine has the beneficial effects that pavement barriers can be avoided, the size is small, motion is flexible, and hidden dangers of vehicle turning caused by unstable gravity center can be prevented.
