A coal mine roadway crawling apparatus based on a wheel-type negative pressure suction mechanism, comprising negative pressure suction wheel-type driving devices (100), a central negative pressure suction device (200), rotary connector devices (300), connecting pipelines (400), and an apparatus body (500). Air extraction outlet ends of the negative pressure suction wheel-type driving devices (100) are connected to and in fluid communications with air extraction inlet ends of the rotary connector devices (300); an air extraction inlet end of the central negative pressure suction device (200) is connected to and in fluid communication with air extraction outlet ends of the rotary connector devices through the connecting pipelines; and the negative pressure suction wheel-type driving devices (100), the central negative pressure suction device (200), the rotary connector devices (300) and the connecting pipelines (400) are respectively mounted on the apparatus body. In practical applications, the apparatus has a greater suction force, is suitable for well roadways with different roughnesses, and is more flexible to move.
