Suspension type limiting switch

The utility model discloses a suspension type limiting switch. The suspension type limiting switch structurally comprises a limiting switch body, a suspension rope, an anti-swing rope, a cable conductor, a fixed magnetic block, movable magnetic blocks, guide rods, contact pieces, normally-closed points, springs and a partition plate with holes. The limiting switch body is installed below hoisting equipment. The lower end of the suspension rope is fixed to the middle position of the upper portion of the limiting switch body. The upper end of the suspension rope is fixed to the lower portion of the hoisting equipment. One end of the anti-swing rope is fixed to one side of the limiting switch body, and the other end of the anti-swing rope is fixed to the position below the fixed end of a steel wire rope of the hoisting equipment. The fixed magnetic block, the movable magnetic blocks, the guide rods, the contact pieces, the normally-closed points, the springs and the partition plate with the holes are arranged inside an inner cavity of the limiting switch body. According to the limiting switch, the phenomenon that limiting of an upper limit of a lifting hook fails due to slippage of a heavy punch can be effectively avoided, and the phenomenon that limiting of the upper limit of the lifting hook fails due to the fact that a travel switch cantilever shaft is locked can also be avoided.
