Summary of the invention
The object of the present invention is to provide a kind of cage traction anti-fall device, after the wire cable rupture of solution conventional elevator, cage easily causes the problem of safety misadventure without any the traction restriction.
The technical solution adopted for the present invention to solve the technical problems is: cage traction anti-fall device, it is characterized in that, comprise towing plate and pull bar, one end of towing plate is fixed on the cage moved up and down along guide rail by the bearing pin activity, a side at towing plate is provided with hook, described towing plate is provided with the guide groove that holds pull bar, described pull bar one end stretches out in the traction plate hole of guide groove end, the other end is provided with the block that is positioned at guide groove, described block is nested with on pull bar spacing by fastening nuts, spring housing is placed on pull bar and between towing plate and block, the other end of pull bar is provided with the eye hitch of connecting steel wire ropes.
Described hook is and the hook-shaped baffle plate for the stull of hook guide rail of towing plate one that towing plate is inclined.
Described hook comprises that an end is flexibly connected towing plate, the other end is flexibly connected the connecting rod of hook-plate, the first side in described hook-plate upper end is provided with the hook for the stull of hook guide rail, lower end is provided with hanging hole, one one section of extension spring is connected in described hanging hole, the other end is connected on guide rail, is provided with the connecting bore swung in order to hook-plate and is connected on guide rail by pin at the hook-plate middle part; Towing plate in vertical state.
Described hook-plate is provided with the slotted eye of bar seam shape, and described connecting rod is connected in slotted eye by pin.
The invention has the beneficial effects as follows: steel rope is realized the traction to cage by pull bar, towing plate, when wire cable rupture, the hook-shaped baffle plate on towing plate or hook-plate deflection, hook the guide rail stull, prevent the effect that cage falls, thereby improve the use safety of equipment.
The accompanying drawing explanation
Fig. 1 is embodiments of the invention one structural representations;
Fig. 2 is the embodiment of the present invention one plan structure schematic diagram;
Fig. 3 is the use constitution diagram of the embodiment of the present invention one;
Fig. 4 is embodiments of the invention two structural representations,
Fig. 5 is the use constitution diagram of the embodiment of the present invention two.
In figure: 1 towing plate, 2 pull bars, 3 pin-and-holes, 4 springs, 5 eye hitcies, 6 hook-shaped baffle plates, 7 stulls, 8 guide rails, 9 cages, 10 fag end suspension plate, 11 connecting rods, 12 extension springs, 13 connecting pins, 31 bearing pins, 61 hanging holes, 62 slotted eyes, 63 hook-plates.
The specific embodiment
As shown in Figure 1 and Figure 2, cage traction anti-fall device, comprise towing plate 1 and pull bar 2, one end pin-and-hole 3 of towing plate 1 is fixed on fag end suspension plate 10 by bearing pin 31 activities, fag end suspension plate 10 is affixed with cage 9, the hook be provided with below towing plate 1 be hook-shaped baffle plate 6 and with the towing plate one.Pull bar 2 is fixed with spring 4 through the other end of towing plate 1 and at the end of pull bar 2, and the other end of pull bar 2 is provided with eye hitch 5.
Towing plate 1 is provided with the guide groove that holds pull bar 2, described pull bar one end stretches out in the traction plate hole of guide groove end, the other end is provided with the block that is positioned at guide groove, and described block is placed on pull bar and by fastening nuts, and spring 4 is placed on pull bar and between towing plate and block.
During work, the haulage cable of elevator is hung on the eye hitch 5 of pull bar 2 front ends, the motor haulage cable pulls pull bar 2, pull bar 2 drives the further cage 9 that drives of (with the guide rail parallel) towing plate 1 tilted and moves along guide rail 8, realize the movement of cage, after the unexpected fracture of steel rope, as shown in Figure 3, pull bar 2 is retracted to prevent from affecting the action of hook-shaped baffle plate under the effect of spring 4 endways, simultaneously because losing traction, towing plate 1 be take bearing pin 3 and is rotated down as axle center, the hook-shaped baffle plate 6 of towing plate 1 below will snap in elevator guide rails stull 7, prevent that cage from continuing to glide, thereby people in cage and the safety of thing have been guaranteed, avoided the accident generation.
As Fig. 4, Fig. 5. be another embodiment of the present invention.With the precedent difference, be.
Hook comprises, one end is flexibly connected towing plate 1 and the connecting rod 11 of other end flexible connection hook-plate 63, the described hook-plate 63 first sides in upper end are provided with the hook for hook guide rail stull 7, lower end is provided with hanging hole 61, one 12 1 sections of extension springs are connected in described hanging hole 61, the other end is connected on guide rail 8, at hook-plate 63 middle parts, is provided with the connecting bore swung in order to hook-plate and is connected to and is led on 8 by pin; Towing plate 1 in vertical state.Described hook-plate is provided with the slotted eye 62 of bar seam shape, and described connecting rod is connected in slotted eye 62 by pin.
The haulage cable of elevator is hung on the eye hitch 5 of pull bar 2 front ends, the motor haulage cable pulls pull bar 2, pull bar 2 drives the further cage 9 that drives of vertical (with guide rail parallel) towing plate 1 and moves along guide rail 8, realizes the movement of cage 9, now extension spring 12 tensionings.
When occurring that unexpected steel rope disconnects the rear haulage plate and is rotated down because deadweight is rotated down and promotes hook-plate 63 by connecting rod along bearing pin, extension spring 12 below hook-plate 63 simultaneously also pulls hook-plate 63 to be rotated down, when encountering the stull 7 of guide rail, hook tangles, thereby prevent that cage 9 from continuing to fall, the safety of bondsman and thing.
