Anti-derailing device for inclined shaft transportation

The utility model discloses an anti-derailment device for inclined shaft transportation, which belongs to the technical field of inclined shaft transportation derailment prevention and comprises a trolley, an upper limiting concave plate is welded on one side of the trolley, and a double-limiting component is arranged in the limiting concave plate. And the double-limiting assembly comprises two first adjusting screw ring blocks arranged in the limiting concave plate, and double sets of adjusting screw rods are inserted into the first adjusting screw ring blocks. By arranging the double limiting assemblies, the second adjusting screw ring blocks and the first adjusting screw ring blocks move along the inner walls of the limiting concave plates in a guiding mode, the two adjacent linkage concave frames can directly achieve extrusion, in this way, the linkage concave frames drive the supporting rods to enable the first rolling wheels to move, and two rubber rings make rolling contact after making contact with a
