At above-mentioned weakness, the purpose of this utility model just provides a kind of Winch Wire Rope Ranging Device, should be able to provide a kind of row the guiding mechanism of restricting to steel rope, when remaining less angle when making steel rope enter reel, provide a size and Orientation all can overcome the mechanism of steel rope by the horizontal applied force that tends to the reel center all the time of fixed pulley generation.
For achieving the above object, the utility model is made up of the afterburning fork and the angle compensation pulley that are arranged between reel and the fixed pulley, the angle compensation pulley is connected in angle compensation pulley base by bearing, angle compensation pulley base is provided with axle in midair, and the axle two ends are connected on the mount pad by bearing in midair.Be vertically installed with afterburning fork with respect to the reel center between reel and the angle compensation pulley, afterburning fork top was provided with rope pulley, and afterburning fork middle part is provided with weight.
Owing to have a said structure, steel rope twines the variation of arranging and deflection angle automatically on the effect lower angle tension pulley of steel rope can be along with reel, the angle when reducing steel rope and entering reel.Cross rope pulley on the afterburning fork and clip steel rope, under the effect of weight horizontal component of force, along with the permutations of steel rope, strengthen or reduce lateral thrust steel rope, steel rope is arranged big more with respect to afterburning fork angle to the reel termination, the thrust that the weight horizontal component of force produces is also big, angle is more little, and thrust is also little, when steel rope is arranged in the reel middle part, angle is zero, and thrust also is zero.Remain less angle when so just having realized making steel rope to enter the volume letter, aspect two of size and Orientations, all can overcome simultaneously the purpose of the horizontal applied force that tends to the reel center all the time that steel rope produces by fixed pulley, make on the capstan drum steel rope marshalling tight, avoided back of the body rope generation of vibration, and the crowded wound of wearing that steel rope is subjected to is less, and also obviously prolong its service life.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is the utility model principle schematic;
Fig. 2 is that afterburning fork A is to scheme drawing;
Fig. 3 is an angle compensation pulley generalized section;
Fig. 1 is the principle schematic that the utility model is applied to railway bridge erecting machine: in the present embodiment, this Winch Wire Rope Ranging Device is made up of afterburning fork 4 and angle compensation pulley 5, wherein angle compensation pulley 5 is connected on the angle compensation pulley base 13 by bearing 12, be provided with axles 8 in midair in the middle of the angle compensation pulley base 13, in midair axle 8 by the radially carrying of hollow end setting radial bearing 7 and the cod 9 of the axial carrying of solid-end setting be connected on the mount pad 14; Be vertically installed with afterburning fork 4 with respect to reel 1 center between reel 1 and the angle compensation pulley 5, afterburning fork 4 tops were provided with rope pulley 6, afterburning fork middle part is provided with weight 3, the quality of the weight 3 on the afterburning fork 4 according to bridge formation machine winch drop hanger 11 when unloaded examination join.After hoisting wirerope 10 comes out from reel 1 through crossing rope pulley 6 on the afterburning fork 4, around angle compensation pulley 5 and pass hollow shaft 8 on the angle compensation pulley base 13, arrive drop hanger 11 through fixed pulley 2 again, steel rope 10 twines the variation of arranging and deflection angle automatically on the effect lower angle tension pulley 5 of steel rope 10 can be along with reel 1, the angle when reducing steel rope 10 and entering reel 1.Cross rope pulley 6 on the afterburning fork 4 and clip steel rope 10, under weight 3 horizontal component of force effects, along with the permutations of steel rope 10, strengthen or reduce lateral thrust steel rope 10, it is pushing away steel rope 10 and is closely arranging round and round when reel 1 is just changeing lifting and receives rope; It is pushing away steel rope 10 and is slowly unclasping in order round and round when rope is put in reel 1 counter-rotating.Steel rope 10 is arranged big more with respect to afterburning fork 4 angles to reel 1 termination, the thrust that weight 3 horizontal component of forces produce is also big, and angle is more little, and thrust is also little, and when steel rope 10 was arranged in reel 1 middle part, angle was zero, and thrust also is zero.Remain less angle when so just having realized making steel rope 10 to enter reel 1, aspect two of size and Orientations, all can overcome simultaneously the purpose of the horizontal applied force that tends to reel 1 center all the time that steel rope 10 produces by fixed pulley 2, make on the capstan drum 1 steel rope 10 marshallings tight, avoided back of the body rope generation of vibration, and the crowded wound of wearing that steel rope 10 is subjected to is less, and also obviously prolong its service life.
