Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the cable Ru Cang mechanism that rope of the present utility model drives comprises the hitch frame 5 that connects by predetermined length pull rope 4 between that arrange to Cabin 3 successively order along supporting cables 1 self-support tower 2 and adjacent one another are, extension pulley 6, several slip coasters 7, support coaster 8, several fixed blocks 9; Described hitch frame 5 is arranged on support tower 2 tops; Described extension pulley 6, slip coaster 7, support coaster 8 and 9 of fixed blocks are set in sequence in supporting cables 1 successively; Cable 10 between support tower 2 and Cabin 3 successively order is fixed with described hitch frame 6 and each coaster; Along with the variation of supporting cables 1 length between support tower 2 and Cabin 3, the distance between described extension pulley 6 and described support coaster 8 changes thereupon.Hitch frame 5 is that one end is fixed on support tower, and the other end stretches out the connecting rod of support tower platform.
Described pull rope 4 length between adjacent described coaster are less than the length of the cable 10 between this, thereby leave certain nargin to the cable 10 between adjacent coaster, avoid cable in the time that adjacent coaster spacing becomes large to be drawn and destroyed.
When operating state, extension pulley 6, slip coaster 7, support coaster 8 are provided with positive stop along the one or both ends of described supporting cables axis direction, minimum spacing when positive stop is used for adjacent described coaster to draw close limits, and the crooked process radius while avoiding each other interference mutually and cable each other to dangle is greater than the minimum bend radius that it allows.
As shown in Figure 2, described extension pulley 6 comprises hauling block installing rack 61, is provided with three bearing rollers 62, two bottom rollers 63 and two supporting cables clamping devices 64 on pulley installing rack; The wheel face of bearing roller and bottom roller is recessed semicircular arc, and when work, described supporting cables 1 is passed in described pulley installing rack 61 inside, in the middle of three bearing rollers 62 and two bottom rollers 63 configure up and down supporting cables 1 is clamped in.
In addition, the quantity of bearing roller and bottom roller can also rationally increase or reduce according to the width of extension pulley, as long as meet the needs of the cable weight that supports certain length.
The one or both ends of supporting coaster and slip coaster are provided with the positive stop similar with the positive stop of extension pulley equally.
Supporting cables clamping device 64 comprises left clamping plate 645 and right clamping plate 643, and is separately positioned in the clamping plate of left and right for clamping upper clamping semi-ring 641 and the lower clamping semi-ring 642 of supporting cables.
