Magnetic energy impact-buffering cart running prevention device for mine inclined shaft

The invention discloses a magnetic energy impact-buffering cart running prevention device for a mine inclined shaft. The device consists of a first-level cart obstruction device, a second-level cart obstruction device, a magnetic resistance device and two slipways, wherein the first-level cart obstruction device consists of a buffering cart and cart obstruction arms; the magnetic resistance device consists of rectangular openings and circular holes which are formed on the slipways in a power decreasing mode, a wedge-shaped permanent magnet, and a permanent magnet part and a magnetic force cutting rotating shaft part which are arranged on the buffering cart; the upper surfaces of the slipways are matched with the bottom surfaces of two steel rails; and travelling wheels and balance wheels on the buffering cart are matched with the lower surfaces and side surfaces of inner grooves of the two slipways. By the device, the defect that an automatic buffering structure is forced to exist due to multilevel steel wire
