Mine cage fixing device

The utility model discloses a mine cage fixing device, including the cage body, the interior diapire symmetric connection of cage body has two guide rails, two through -holes have been seted up to thelateral wall symmetry of guide rail, this mine cage fixing device simple structure, through the integrated configuration of adding iron set and T shape clamp plate, the in -process that the mine carwas pushing can slowly move the slide bar to pushing down, make two unlucky moving of permanent magnetism iron phase to pass the through -hole through the connecting rod, simultaneously, the permanentmagnet is close to the iron set, make also move and pass the through -hole of two iron sets, utilize permanent magnet and iron set to block the mine car, and when two iron set move, stimulate the wedge downwards through the stay cord, be roll connection because of wedge and T shape clamp plate, two T shape clamp plate move further block the mine car, increase fastening power, avoid the in -process of cage body in the motio
