Abstract
The utility model relates to an execution part winding drum for a lifting device of hoisting machinery, in particular to a spiral rope groove winding drum with a wedge-shaped groove, belonging to the technical field of engineering machinery and comprising the winding drum and the wedge-shaped groove between the winding drum and the inner side of a flange; and the size parameter of the wedge-shaped groove needs to be matched with the pitch of a rope groove and the diameter of the winding drum. When a steel wire rope is wound to the side edge of the flange and the upper-layer winding is carried out, and as the structure of the wedge-shaped groove leads the two adjacent layers of steel wire rope to generate offset m, and simultaneously generate a slip inclined angle alpha, the component force F is increased along the winding direction of the steel wire rope, the steel wire rope enters a correct winding position by the wedge-shaped groove smoothly, thus effectively avoiding the steel wire rope from generating rope climbing phenomenon in a plurality of layers, and effectively reducing wear and extrusion of the steel wire rope at the cross point position of the steel wire rope.
Description
Technical field
The utility model relates to a kind of execution unit reel that is used for the elevator machinery jack up unit, and a kind of specifically spiral drum slot reel that has webge slot belongs to technical field of engineering machinery.
Background technology
At construction machinery industry, be used for the coiling that the traditional spiral drum slot reel of crane hoisting device generally is applicable to the individual layer steel rope at present.Because of spiral drum slot has the low advantage of the simple cost of manufacturing, still in multiple wraps, be extensive use of at present.Traditional spiral drum slot reel is owing to can't be provided with the steel rope voussoir, steel rope is at the crossover point place of beginning n layer in the multiple wraps, rope climbing, disorder cable phenomenon appear easily, especially when steel rope angle of deviation β spends less than 0.5, occur the steel rope packing phenomenon easily, i.e. this phenomenon in case take place in rope climbing phenomenon, light then cause the sharp wear of steel rope, cause the steel rope premature failure; Heavy then steel rope is stacked into to a certain degree, outside the reel flange of scurrying out, causes steel rope moment fracture, causes a serious accident, and brings very big hidden danger for workman's personal safety and enterprise security production.
The utility model content
The utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of spiral drum slot reel that has webge slot is provided, it includes between reel, reel and the flange inboard webge slot, and the dimensional parameters of webge slot must be complementary with grooving pitch, drum diameter.When steel rope is wound into the flange side and carries out the last layer winding, because the structure of webge slot, make adjacent two-layer steel rope produce side-play amount m, produce the slippage inclination alpha simultaneously, thereby increased component F along the steel rope winding direction, steel rope enters correct winding position smoothly by webge slot, and the rope climbing phenomenon of effectively avoiding steel rope to occur in multiple wraps has effectively alleviated wearing and tearing and extruding at steel rope crossover point place steel rope.
The utility model is realized with following technical scheme: a kind of spiral drum slot reel that has webge slot, it includes reel, there is flange at the reel two ends, is tied with steel rope on the reel, it is characterized in that: between reel and the flange inboard webge slot is arranged.
Described reel two ends have steel rope to be connected with track adjusting wheel.
The utility model has the advantages that: this spiral drum slot reel structure is simple, practical, because the structure of webge slot is arranged between reel and flange inboard, can effectively solve the harm that brings when the steel rope angle of deviation is spent less than 0.5, prolong the service life of steel rope widely, reduced harmful impact load that steel rope occurs in banking process.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the utility model structural representation:
Fig. 2 is the utility model wedge-shaped groove structure scheme drawing:
Among the figure: 1, reel, 2, flange, 3, the flange inboard, 4, steel rope, 5, webge slot, 6, track adjusting wheel.
The specific embodiment
As shown in the figure: a kind of spiral drum slot reel that has webge slot, it includes reel 1, there is flange 2 at the reel two ends, is tied with steel rope 4 on the reel, between reel and the flange inboard 3 webge slot 5 is arranged.
Described reel 1 two ends have steel rope 4 to be connected with track adjusting wheel 6.
The dimensional parameters of described webge slot and grooving pitch, drum diameter are complementary.When steel rope is wound into the flange side and carries out the last layer winding, because the structure of webge slot, make adjacent two-layer steel rope produce side-play amount m, produce the slippage inclination alpha simultaneously, thereby increased component F along the steel rope winding direction, steel rope enters correct winding position smoothly by webge slot, and the rope climbing phenomenon of effectively avoiding steel rope to occur in multiple wraps has effectively alleviated wearing and tearing and extruding at steel rope crossover point place steel rope.
