Accompanying drawing explanation
Fig. 1 is that the present invention is slowed down the locations of structures schematic diagram of percussion lock.
Fig. 2 is the locations of structures schematic diagram that the present invention is decelerated to shutdown feature.
Detailed description of the invention
Below in conjunction with Fig. 1, Fig. 2, the present invention is described in detail, is clearly and completely described the technical scheme in the embodiment of the present invention, and obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment: the shutdown feature that is decelerated to of a kind of elevator box fall-proofing device of the present invention realizes by the following technical solutions: comprising: snap lock 13, radius stay 14, axle 15, U-shaped draw-in groove 22, big gear wheel 16, miniature gears 19, electrical motor 17, treater 18, accumulator jar 20, deceleration axle 21, ratio wheel 23, brake gear 24, inclined-plane 25; Be further characterized in that and comprise: deceleration percussion lock.
The present embodiment is set to further: described deceleration percussion lock is made up of snap lock 13, radius stay 14, axle 15, U-shaped draw-in groove 22, big gear wheel 16, miniature gears 19, electrical motor 17, treater 18, accumulator jar 20, deceleration axle 21; Described snap lock 13, be have elastomeric lock, and radius stay 14 matches, and in normal condition, pins radius stay 14, but when electrical motor works, snap lock 13 allows radius stay 14 pass through; Described radius stay 14 is fixed on one end of axle 15; The other end of described axle 15 fixes big gear wheel 16, the U-shaped bottom of middle fixing U-shaped draw-in groove 22; Described U-shaped draw-in groove 22 U-shaped in be deceleration axle 21; Described deceleration axle 21 is on inclined-plane; Described miniature gears 19 and big gear wheel 16 are engaged mutually, and miniature gears 19 is arranged on electrical motor 17; What connect between described electrical motor 17 and accumulator jar 20 is treater 18; The signal that described treater 18 accepts arc detecting device exports; The described shutdown feature that is decelerated to is made up of ratio wheel 23, brake gear 24, inclined-plane 25; Described ratio wheel 23 is arranged on deceleration axle 21, and hoistway wall (or elevator case fixed track) is corresponding, and be contacting and separating two states between the two; Described brake gear 24 is arranged in ratio wheel 23; Described inclined-plane 25, is arranged on elevator box, in outward direction, makes to be provided with the elevator box of inclined-plane 25 part and the distance of hoistway wall (or elevator case fixed track) is up-narrow and down-wide.
