Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention 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, the present invention is run 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.
