The specific embodiment
In order to understand better the utility model, below in conjunction with embodiment and accompanying drawing, the technical solution of the utility model is described further to (referring to Fig. 1 to Fig. 6).
A kind of device that prevents the de-groove of steel wire rope of windlass, as shown in Figure 1 and Figure 2, it comprises support 3, road wheel 7 and pivot shaft 8, described road wheel 7 is enclosed within on pivot shaft 8, the two ends of pivot shaft 8 are separately fixed at (described support 3 is fixed on lifting drum pedestal 6, and pivot shaft 8 is parallel with lifting drum 1) on two supports placed side by side 3; Described road wheel 7 outsides are provided with a circle arc groove, described arc groove be complementary with steel rope 2 (described steel rope 2 contacts with arc groove); Described road wheel 7 can rotate and move vertically on pivot shaft 8.
Describedly prevent that the device of the de-groove of steel wire rope of windlass from also comprising base 5, described support 3 is fixed on base 5, is provided with one deck between support 3 and base 5 and adjusts pad 4.Adjust the height of pad 4 by adjusting, accurately control the relative position of road wheel 7 and lifting drum 1 grooving.
The inboard of described road wheel 7 is provided with a circle groove, is inlaid with axle sleeve 10 in groove, and axle sleeve 10 is enclosed within (as shown in Figure 3) on pivot shaft 8.Described axle sleeve 10 materials adopt elastomeric material.
The inboard of described road wheel 7 is provided with antifriction-bearing box, and antifriction-bearing box is enclosed within on pivot shaft 8.
The top of described road wheel 7 outer arcuate grooves is precipitous, and the bottom transition should be mild.Like this, when steel rope 2 has de-groove trend, can make the axial component of steel rope 2 more be delivered to the horizontal direction of road wheel 7, to reduce its circumferential direction component, can reduce like this friction and wear between road wheel 7 and pivot shaft 8, also reduce its resistance when power being provided to road wheel 7, make the axially reciprocating of road wheel 7 on pivot shaft 8 more smooth and easy, the life-span that is conducive to improve this device.
The two ends of described pivot shaft 8 are equipped with fixedly baffle ring 9.
The fixing of described pivot shaft 8 can adopt better simply seam to fix, to guarantee that pivot shaft 8 does not rotate.
In order to protect steel rope 2 and lifting drum 1, the material property of described road wheel 7 is a little less than steel rope 2 and lifting drum 1.
Connection mode between described road wheel 7 and pivot shaft 8 can adopt conventional axle sleeve to connect; also can adopt antifriction-bearing box to add the axle sleeve mode; perhaps antifriction-bearing box adds the modes such as plain bearing; can on pivot shaft 8, rotate and move vertically as long as meet road wheel 7, all should fall into and belong to the scope that the utility model is protected.
Just be equipped with a set of device that prevents the de-groove of steel wire rope of windlass while in technique scheme, on lifting drum 1, only having steel cable 2; While on lifting drum 1, many steel ropes 2 being arranged (described many are generally two), will mate the devices that many covers prevent the de-groove of steel wire rope of windlass, many covers prevent that the devices of the de-groove of steel wire rope of windlass are arranged in juxtaposition, separate, be independent of each other.
Principle of the present utility model (as shown in Fig. 4, Fig. 5, Fig. 6): the arc groove in above line travelling wheel 7 outsides and the grooving of lifting drum 1 form a semi-enclosed zone.Like this, steel rope 2 just is limited in this zone, as shown in Figure 6.When steel rope 2 loading angles change, when de-groove trend is arranged, steel rope 2 is inevitable can produce an axial component simultaneously, is referred to as axial force.When axial force is greater than friction force, road wheel 7 can be driven, realizes its axial motion; Like this, road wheel 7 is without providing separately propulsion source, also without driver train is provided, just can automatically keep the relative position with lifting drum 1 grooving, to reach the purpose of de-groove of steel rope 2.
Above embodiment is only the preferred version of the utility model; but not to restriction of the present utility model; person skilled in the relevant technique; in the situation that do not break away from spirit and scope of the present utility model; can also make various conversion or modification; therefore all technical schemes that are equal to, all fall into protection domain of the present utility model.
