Description
Technical field
The utility model relates to a kind of rope guide, and specifically the plain line rope guide of a kind lifting mechanism of tower crane, belongs to tower crane equipment technical field.
Background technology
At present, the rope guide of most lifting mechanism of tower crane is equal diameter rope guide, in years'experiences, find to there is following problem:
1. by wirerope-winding row rope sheave after, form drift angle α with vertical plane; Owing to there being the existence of drift angle a, the pulling force of steel rope produces on row's rope sheave the component that one is pointed to drum center; The row's of making rope sheave vacillates speed faster than row's rope speed, and the row's of causing rope is sparse, then causes disorder cable.
2. utilize comparatively thick shorter reel to substitute longer thinner reel, this method does not fundamentally solve the sparse problem of longer thinner reel two ends row's rope, and decreases lifting mechanism appearance rope amount to a certain extent, adds steel rope use cost.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of lifting mechanism of tower crane plain line rope guide, avoid lifting mechanism to arrange the sparse phenomenon of rope two ends row's rope, reduce lifting mechanism disorder cable phenomenon, the row's of lifting rope sheave and service life of steel wire rope.
To achieve these goals, the utility model comprises steel rope, reel, row's reel for rope and row's rope sheave; Wherein, row rope sheave center has circular hole, the external diameter of the aperture correspondence row reel for rope of circular hole, and row's rope sheave is actively set on row's reel for rope by circular hole; Reel has common line of centers with row's reel for rope, and two ends are on same vertical plane; Steel rope forms point of contact with row's rope sheave, and steel rope and vertical plane form drift angle α.
On the basis of said structure, row's reel for rope is plain line row reel for rope, its plain line is one section of camber line, the center of circle of camber line is the intersection point that the normal of drift angle α and line of centers are formed, the radius of camber line is the length of normal degree formed between intersection point and point of contact, and two end points of camber line are the intersection point of row's reel for rope two end faces and vertical plane; The plain line of the circular hole correspondence row reel for rope that row opens at rope sheave center, row's rope sheave is by the side of circle hole sleeve at row's reel for rope.
Further, the circular hole opened at rope sheave center and row's reel for rope decentraction is arranged.
Further, the diameter 0-1mm larger than the diameter of row's rope sheave of the circular hole that rope sheave center is opened is arranged.
Further, reel for rope smooth surface is arranged.
Principle of work: when wire rope winding is to reel side, because row's reel for rope is plain line row reel for rope, belong to multidiameter shaft, therefore, when row's rope sheave is in diverse location thereon, hole between centers has different gaps, the wedge gap produced between axis hole can produce a deflection angle around row's reel for rope by the row's of making rope sheave, rope sheave just in the normal of row's rope sheave steel rope, thus is arranged to the axial force between steel rope in balance row rope process in the direction of the row's of making rope sheave, realizes steadily arranging rope.
In conjunction with principle of work, the phenomenon that when the utility model avoids wire rope winding, reel both sides steel rope is sparse, decreases lifting mechanism disorder cable phenomenon, extends the row's of lifting rope sheave and service life of steel wire rope, has value of service widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is working state schematic representation of the present utility model.
In figure: 1, arrange rope sheave, 2, point of contact, 3, row's reel for rope, 4, steel rope, 5, line of centers, 6, reel, 7, normal.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the plain line rope guide of a kind of lifting mechanism of tower crane, comprises steel rope 4, reel 6, row's reel for rope 3 and row's rope sheave 1; Wherein, described row's rope sheave 1 center has circular hole, the external diameter of the aperture correspondence row reel for rope 3 of circular hole, and row's rope sheave 1 is actively set on row's reel for rope 3 by circular hole; Reel 6 has common line of centers 5 with row's reel for rope 3, and two ends are on same vertical plane; Steel rope 4 forms point of contact 2 with row's rope sheave 1, and steel rope 4 and vertical plane form drift angle α.
On the basis of said structure, described row's reel for rope 3 is plain line row reel for rope, its plain line is one section of camber line, the center of circle of camber line is the intersection point that the normal 7 of drift angle α is formed with line of centers, the radius of camber line is the length of the normal 7 formed between intersection point and point of contact 2, and two end points of camber line are the intersection point of row's reel for rope 3 two end faces and vertical plane.The plain line of the circular hole correspondence row reel for rope 3 that described row's rope sheave 1 center is opened, row's rope sheave 1 is by the side of circle hole sleeve at row's reel for rope 3.
Further improve as the utility model, the circular hole that row opens at rope sheave 1 center and row's reel for rope 3 decentraction.Above-mentioned design, the row's of making rope sheave 1 hole wall moves on the element line of row reel for rope rear, rotates around own axes, further avoid steel rope 4 and arranges the phenomenon that when restricting, reel 6 both sides steel rope is sparse.
Further improve as the utility model, the diameter 0-1mm larger than the maximum gauge of row's reel for rope 3 of the circular hole that row opens at rope sheave 1 center.
Further improve as the utility model, row's reel for rope 3 smooth surface, provides lubricant effect better.
Shown in composition graphs 2, in the operation of reality, when steel rope 4 arranges rope to reel 6 side, because row's reel for rope 3 is plain line row reel for ropes, belong to multidiameter shaft, therefore, when row's rope sheave 1 is in diverse location thereon, hole between centers has different gaps, the wedge gap produced between axis hole can produce a deflection angle around row's reel for rope 3 by the row's of making rope sheave 1, rope sheave just in the normal of row's rope sheave steel rope 4, thus is arranged to the axial force between steel rope in balance row rope process in the direction of the row's of making rope sheave 1, realizes steadily arranging rope.
Shown in structure of the present utility model and principle of work, the phenomenon that when the utility model avoids wire rope winding, reel both sides steel rope is sparse, decrease lifting mechanism disorder cable phenomenon, extend the row's of lifting rope sheave and service life of steel wire rope, there is value of service widely.
