SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hook assembly's wire rope protection device to the hook assembly who provides in solving above-mentioned background art probably leads to wire rope wearing and tearing, the problem of disconnected silk when askew drawing hangs to one side.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a wire rope protection device of lifting hook pulley block, including two pulley housing, two the equal fixed mounting in one side that the pulley housing is close to each other has the arm-tie, one side that two arm-ties are close to each other rotates installs same lifting hook crossbeam, the top side fixed mounting of lifting hook crossbeam has the lifting hook nut, rotate on the lifting hook nut and install the gib head, one section of gib head runs through the lifting hook crossbeam, be fixed with same loose pulley shaft on two pulley housing, the equal movable mounting in both ends of loose pulley shaft has the pulley, the rope groove has all been seted up on two pulley housing, equal movable mounting has the sheath in two rope grooves, the mounting groove has all been seted up at the both ends of sheath.

Preferably, two the arm-tie is last all to have seted up the arm-tie hole, and the both ends of lifting hook crossbeam rotate respectively to be installed at two arm-tie downtheholess.

Preferably, the lifting hook cross beam is provided with a cross beam hole, and the hook head penetrates through the cross beam hole.

Preferably, the sheath is provided with a sheath opening, and the sheath opening is communicated with the rope outlet groove.

The beneficial effects of the utility model are that:

the utility model discloses in, through the setting of sheath, through suitably increaseing out the rope mouth size, at a rope mouth position installation sheath, wire rope passes through in the sheath, can contact the sheath on the pulley housing when crooked appears in the steel wire on the pulley, can prevent that pulley housing and wire rope from wiping wearing and tearing when askew drawing hangs to one side, and then prolonged the life of steel wire.

The utility model discloses in, through the setting of gib head, mousing-hook, pulley for when the lifting hook assembly used the gib head to hoist, the steel wire cup jointed on the opening of gib head, can drive the mousing-hook and open automatically, when the steel wire landing gib head is inside, can make the automatic closure of mousing-hook under the promotion of torsional spring, thereby can prevent that the slippage from appearing at hoist and mount in-process steel wire, play the protection effect, promoted the security.
