Lifting limiting device for steel wire rope on winding drum

Abstract

The invention discloses a lifting limiting device for a steel wire rope on a winding drum. The lifting limiting device comprises the winding drum, a winding drum support, a platform, the steel wire rope and a power device, wherein one side of a mandrel of the winding drum is connected to the power device, the other side of the mandrel of the winding drum is connected to the winding drum support, the steel wire rope is connected to the winding drum, the winding drum support and the power device are fixed to the platform, one end of the steel wire rope vertically extends downwards to the position below the platform after being led out from the winding drum, two lifting limiting device bodies are arranged on the side, from which the steel wire rope led out, of the winding drum and are distributed on the two sides of the vertical downward part of the steel wire rope, supports of the two lifting limiting device bodies are fixed to the platform, and contact handles of limiting switches on the lifting limiting device bodies can make contact with the steel wire rope.

Description

technical field [0001] The present application relates to the field of cranes, and in particular to a lifting limiting device for steel wire ropes on a drum. Background technique [0002] The wire rope wound on the drum is equipped with a lifting limit device to prevent the accident of the top rushing caused by the over-rolling, or to prevent the accident of the wire rope falling off due to the excessive fall; therefore, the high limit device is an important part of the crane; the existing drum The lift stop is an internally threaded shaft switching device A ( figure 1 shown in ), the threaded shaft has a slider that can move left and right, the threaded shaft is connected with the reel shaft, rotates with the reel, and the slider moves left or right to touch the electrical switch set next to the slider , the corresponding switch works and cuts off the power supply to realize the work of the lifting limiter; but the threaded shaft in this lifting limiter is relatively small...
