Embodiment
Be described further below in conjunction with embodiments of the invention and accompanying drawing thereof structure contactless trailing cable drum device.
Illustrated in figures 1 and 2 is the overall structure schematic diagram of contactless trailing cable drum device embodiment of the present invention, this device is made up of bracing frame 18, outer reel 10, internal layer reel assemblies and volute spring 6, the internal layer reel assemblies comprises several cylinder stulls 4, bearing 8, bearing cap 9, left spindle nose 11 and right spindle nose 12, wherein, several cylinder stulls 4 constitute the hollow shaft that can twine cable; Two ends in the internal layer reel assemblies are equiped with bearing 8 respectively, and left spindle nose 11 and right spindle nose 12 are spirally connected with the bearing cap at hollow shaft two ends respectively.Shown in Figure 3 is the enlarged drawing of internal layer reel assemblies among Fig. 1, the termination of left side spindle nose 11 is provided with opening, one baffle plate 1 is stuck in the opening, the affixed cable intermediate plate 2 in baffle plate 1 top, and this baffle plate 1 and cable intermediate plate 2 constitute a cable inlet (as shown in Figure 3) on the left side of internal layer reel assemblies.At the right-hand member of internal layer reel assemblies one coil spring seat 7 is installed, this coil spring seat is loaded on the right outside of outer reel, and it is affixed with internal layer reel assemblies right-hand member bearing cap, volute spring 6 is housed in the coil spring seat, volute spring 6 is sleeved on the termination of right spindle nose 12, one end of this volute spring is fixed in the fluting 13 of right spindle nose termination, and volute spring end 21 is fixed in (with reference to figure 3, Fig. 4) on the volute spring fixed axis 20.
In the present embodiment, the center of outer reel 10 is a circular hole, and its diameter equates that with the cylindrical of internal layer reel assemblies bearings at both ends 8 outer reel is embedded on the bearing at internal layer reel assemblies two ends, and is spirally connected by bearing cap 9; The spindle nose at internal layer reel assemblies two ends sets up and is fixed in the U type mouth of bracing frame 18, and outer reel rotates by bearing.This structure becomes one outer reel and internal layer reel assemblies, and the spindle nose at internal layer reel assemblies two ends sets up and is fixed in the U type mouth of bracing frame 18, makes that the internal layer reel assemblies is motionless, and outer reel 10 is by the bearing rotation at internal layer reel assemblies two ends.
Referring to Fig. 5, when using this device, flat cable 19 enters on the hollow shaft of being made up of several cylinder stulls 4 from the baffle plate 1 and the cable inlet between the cable intermediate plate 2 of internal layer reel assemblies one end, wire clamp sheet 3, line ball clip 5 and cylinder stull 4 compress the inner of flat cable 19, on hollow shaft, twine a few, twine to taking turns by several on support 14 outer reels of forming 10 again.On outer reel 10, be provided with several stulls 15, wire clamp 16 and line ball folder 17 is housed in the stull of a relevant position therein, flat cable is compressed.Flat cable 19 is opposite with the winding direction of flat cable on internal layer reel assemblies hollow shaft at the winding direction on the outer reel, twines the number of turns and equates.
Drive flat cable 19 and discharge when suspension equipment (suspension rod) descends, outer reel 10 rotates, and this moment, volute spring 6 was in rolling-in energy storage state.When suspension equipment (suspension rod) rose, volute spring 6 entered that releases can state, drives outer reel 10 backward rotation, thereby realized that flat cable reels on outer reel, draws over to one's side, and also did corresponding coiling on the internal layer reel assemblies.When suspension equipment lifting during to the height that needs, because the effect of volute spring, make the stressed poised state that is in of reel, reel will stop with suspension equipment.
Contactless cable drum device of the present invention is without slip ring and brush, by the rotation of outer reel, drive twisted and released of the cable, and drive cable simultaneously and on the internal layer reel, makes corresponding coiling, thereby avoided reversing of cable stiff end, realized contactless current delivery; By the effect of volute spring, make the stressed poised state that is in of reel simultaneously, realized the synchronous operation of cable with lifting means.
