The invention discloses a mine underground inclined roadway lifting transportation pneumatic normally-closed vehicle stopping device, and relates to the technical field of coal mine transportation machinery and machining. Comprising a pneumatic gear transmission car arrester, a pneumatic car stopping fence, a pneumatic control box and a signal device, the car arrester and the pneumatic car stopping fence can achieve the combined linkage locking function according to set positions and are both controlled by the pneumatic control box, and the signal device is used for displaying the state of the whole device and sending out voice prompts. The car arrester comprises an air cylinder, a crank structure, a heavy collision block, a sector gear and two pinions, and the air cylinder drives the gears to rotate so that the car arrester can be opened or closed. The pneumatic arrester comprises an air cylinder, an arrester body, a vertical rope guide wheel device, a double-rope guide wheel device and an air cylinder push rod wheel set. According to the invention, car sliding and sliding accidents can be effectively prevented; the installation and the operation are convenient; uncoupled vehicles can be prevented from sliding into an inclined roadway; an uncoupled vehicle is prevented from continuously running down after passing through the grade change point; and violation overloading of vehicles is prevented.
