In order to achieve the purpose of the invention, the technical scheme of the utility model is as follows: a double-drum high-winch lifting structure comprises two lifting drums, steel wire ropes, an X balance beam, a Y balance beam, a fork-shaped piece and a hook assembly, wherein the axis connecting line of the lifting drums is horizontally arranged, the steel wire ropes are wound on the lifting drums, and each lifting drum is symmetrically provided with two steel wire ropes; the bottom end of the steel wire rope is fixedly connected with an X balance beam, the X balance beam is hinged with a Y balance beam through a fork-shaped piece, and the X balance beam is vertical to the Y balance beam; the lifting hook assembly is hinged to the middle of the Y-shaped balance beam.

Furthermore, the bottom end of the steel wire rope is hinged with two ends of the X balance beam through wedge-shaped joints.

Further, the top of X compensating beam middle part through articulated shaft and fork type spare is articulated the setting each other, the bottom of fork type spare is articulated the setting each other through the tip of articulated shaft and Y compensating beam.

Further, the tip of articulated shaft is provided with the spacing groove, the spacing inslot joint cooperation is provided with spacing cardboard, spacing cardboard passes through the fastener and can dismantle the setting on the lateral wall of fork type spare.

Furthermore, the hoisting winding drum is a multilayer broken line type winding drum, two steel wire rope winding grooves are symmetrically formed in each winding drum, and an independent steel wire rope is symmetrically wound in each steel wire rope winding groove.

The utility model discloses a two reel height hoist hoisting structure's beneficial effect:

1. the utility model discloses a two reel height hoist hoisting structure is provided with mutually perpendicular's X, Y compensating beam, deuterogamies fork type spare and four wire rope that play to get off on the play reel, finally forms four-point hinge structure, can play automatic leveling's effect when four wire rope length nonconformities that play to get off on the play reel to make the lifting hook subassembly perpendicular downwards all the time, guarantee the stability and the reliability of jack-up colluding.

2. The utility model discloses a two reel height hoist hoisting structure, it plays to rise the reel and can design into multilayer broken line type, and the multilayer broken line combines single rope multiplying power to be 1's design, can shorten the length of reel greatly, and finally reaches appearance structure when high hoist also not too huge, and the installation is simple relatively, and the transportation is more convenient.
