Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment one
Refer to Fig. 1 to Fig. 3, a kind of elevator over-speed governor tensioning apparatus, comprise tension wheel 9, a pair connecting panel 8, guar plate 1, reset switch beat rod 5, pair of sliding block 7, a pair bending grillage 6 and pair of guide rails 10.A pair connecting panel 8 along tension wheel 9 radial parallel setting and be separately fixed on the two ends of the rotating shaft of tension wheel 9, the bottom of each connecting panel 8 is all provided with sliding part 7, pair of sliding block 7 lays respectively at the both sides of tension wheel 9, the top of one of them connecting panel 8 is fixedly connected with guar plate 1, the two ends of guar plate are installed with clump weight 4, and the top of another connecting panel 8 is provided with the reset switch extended downward and plays rod 5.As shown in Figure 2, guar plate 1 is arranged on the upper end of left side connecting panel 8, and the top that rod 5 is arranged on the connecting panel 8 on right side beaten by reset switch.
A pair bending grillage 6 is oppositely arranged and is fixed on shaft bottom, and is positioned at the below of tension wheel 9, and a pair bending grillage 6 lays respectively at the both sides of tension wheel 9, is clipped in wherein by tension wheel 9.The medial surface of each bending grillage 6 is respectively equipped with the guide rail 10 that only can slide up and down cooperation for sliding part 7, pair of guide rails 10 is oppositely arranged and coordinates with pair of sliders 7 one_to_one corresponding.As shown in Figure 2, the sliding part 7 on the left of tension wheel 9 only can slide up and down to coordinate with the guide rail 10 in left side, and the sliding part 7 on the right side of tension wheel 9 only can slide up and down to coordinate with the guide rail 10 on right side.Wherein, sliding part 7 preferably leads boots.Adopt and lead boots 7 and to match with guide rail 10 structure of sliding, make the utility model operation more reliable and more stable.
As shown in Figure 2, the lateral surface of the bending grillage 6 on right side is also provided with the switch that is reset to beat after rod 5 touches and send the reset switch 3 disconnecting elevator safety loop signal.When the speed limiter wire rope be connected with tension wheel 9 relaxes, under the effect of clump weight 4, tension wheel 9 moves downward, the sliding shoe 7 of tension wheel 9 both sides is along guide rail 10 slide downward, after slide displacement exceedes certain distance, rod 5 played by reset switch can trigger reset switch 3, sends and disconnects elevator safety loop signal, cause power-off, remind and again tighten up speed limiter wire rope.
In the present embodiment, its length direction of guar plate 1 extends along the horizontal direction perpendicular with the axial line of tension wheel 9.The quantity of clump weight 4 is two, and two clump weights 4 are fixedly connected on the two ends in its length direction of guar plate 1 respectively, two clump weights 4 with the omnibearing line vertically through the axle center of tension wheel 9 for symmetrical center line is that specular is arranged.Guar plate 1 length is in the horizontal direction longer, and the clump weight 4 at its two ends is equal in weight, and guarantee that the center of gravity of over-speed governor tensioning apparatus is positioned at center and height of gravitational center is lower, over-speed governor tensioning apparatus runs more stable up and down.
In order to avoid speed limiter wire rope departs from from tension wheel 9, the side of tension wheel 9 is also installed with the rope blocking plate 2 that the radial direction along tension wheel 9 extends, and rope blocking plate 2 and one of them connecting panel 8 are fixed together.In the present embodiment, rope blocking plate 2 extend in the horizontal direction and two ends towards the bending of tension wheel 9 opposite side, dogleg section crosses over the grooving on the outer circumference surface of tension wheel 9, speed limiter wire rope, between the dogleg section of rope blocking plate 2 and the grooving of the outer circumference surface of tension wheel 9, avoids steel rope to depart from tension wheel 9.
The installation site of clump weight is improved by the over-speed governor tensioning apparatus of the present embodiment, structure is compacter, shaft space occupation is little, especially only takies very little hoistway space at vertical direction, and the over-speed governor tensioning apparatus of the present embodiment is adapted to be mounted within the limited elevator device of hoistway space.In addition, slide up and down relative with guide rail of slide block that move through of the tension wheel of the over-speed governor tensioning apparatus of the present embodiment limits, make this plant running more reliable and more stable, and tension wheel is all the time all along lifting rail, substantially reduces the wearing and tearing of speed limiter wire rope.
Above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
