Embodiment
In order to deepen the understanding to the utility model, the utility model is made below in conjunction with embodiment and attached drawing further
It is described in detail.
Embodiment 1：As shown in Figure 1 and Figure 2, a kind of anti-fall device, including locking device are flat on locking device with being articulated with
Weigh device, and balancing device can be swung up and down as lever on the locking apparatus, and situation about swinging up and down is to be according to elevator
No fall and acted on.
Locking device includes anti-fall cylinder 1, and anti-fall cylinder is sleeved on steel strand wires, and anti-fall cylinder bottom is set with fixing sleeve,
Fixing sleeve is tightly fastened with anti-fall cylinder, is sleeved on jointly on steel strand wires, and anti-fall cylinder sidepiece is equipped with pin hole 2, and lock is provided with pin hole
Rationed marketing 3, stop pin is through on pin hole, and the length of stop pin is longer than pin hole, is set with spring 1 on stop pin, spring one be
In pin hole, while the right end for ensconcing that a part of stop pin inside pin hole is equipped with catch 5, and catch 5 is to be used to that pin card will to be locked
It is blocked in pin hole, prevents stop pin to be ejected, and one block of spring is between pin hole and catch, when there is power in outside
During effect, stop pin 3 can laterally press against spring one, and stop pin is to stretching into inside anti-fall cylinder 1, when not having a strong effect, in bullet
Under the action of spring one, stop pin can be ejected inside the anti-fall cylinder, until positioning pin by block at catch；It is sky inside anti-fall cylinder
Chamber, cavity are divided into the cylindrical cavity 6 on top, the round platform chamber 7 of lower part, the top wedge for being set on steel strand wires are provided with cylindrical cavity
8 are covered, and pushes up cover of wedge to move up and down in cylindrical cavity, block block 14 is provided with the top of the cover of wedge of top, block block outside diameter is more than circle
Column intracavitary footpath, top cover of wedge length are more than cylinder cavity length, are set with spring 3 10 below block block, and three block of spring is in block
Between block and anti-fall cylinder, when when top, cover of wedge moves downward, block block can compress spring three, and top cover of wedge sidepiece is provided with and stop pin
Matched groove 9, when the effect of groove 9 is that top cover of wedge is pressed downward, when being pressed onto certain degree, stop pin can be stuck in groove,
Shape and push up the location status of cover of wedge 8；Round platform intracavitary is provided with the clip device for stepping up, unclasping steel strand wires 17, intermediate plate dress
Putting can move up and down in round platform intracavitary, and clip device bottom is provided with spring 2 10, and clip device can press during pushing
Spring 2 10, spring 2 10 is installed between clip device and fixing sleeve, and cylindrical cavity internal diameter is more than round platform top of chamber internal diameter,
Top cover of wedge outside diameter is less than cylindrical cavity internal diameter, and pushes up the diameter that cover of wedge bottom diameter is equal to clip device top, pushes up the lower end of cover of wedge
All the time it is in contact with clip device, clip device forms frustum cone structure, and round platform knot by section for trapezoidal arcuation intermediate plate 16
Structure matches with round platform chamber top size, and arcuation intermediate plate is 3 pieces, and arcuation intermediate plate is respectively not attached to around composition round platform, arcuation folder
Piece is internally provided with for increasing the twill travel permit with 17 frictional force of steel strand wires；Top cover of wedge 8 push, i.e., can push down clip device and then
Push, make 3 pieces of arcuation intermediate plates in clip device that loose state be presented, will not be drawn close to steel strand wires, steel strand wires can be at this time
Smoothly slided up and down in top cover of wedge 8, clip device, without any frictional force, if top cover of wedge does not push clip device, intermediate plate dress
Put and can recover upwards under the action of spring 2 10, since the space of round platform chamber upper end is less and less, so on 3 pieces of arcuation intermediate plates
It can also be gathered during rising, so that clip device can clamp steel strand wires, balance relative static conditions kept with steel strand wires.
Balancing device includes being articulated with the L-shaped lever 11 on the outside of anti-fall cylinder, and L-shaped lever one end is provided with clump weight 12, separately
One end is provided with the baffle 13 for push and block stop pin, and when elevator normally upper decline, clump weight 12 is by leverage by keeping off
The stop pin that plate 13 pushes down outer bullet trend is in equilibrium state, i.e. baffle 13 promotes stop pin 3, and stop pin 3 is to be stuck in top wedge
In the groove 9 of set, the state of clip device is press against under top cover of wedge of shaping, clip device will not rise, then arcuation intermediate plate 16 is not
Steel strand wires can be clamped；Once if used during elevator falling, when elevator accelerates to decline, clump weight 12 can be weightless, under the action of inertia, matches somebody with somebody
Pouring weight can be swung up, lever principle, and baffle 13 is then to lower swing, and baffle no longer push and block stop pin 3, then stop pin is in spring one
It is released under the action of 4 and ejects to the right, and then positioning pin pop-up out of top cover of wedge groove 9, push up cover of wedge and clip device difference
Under the rebound effect of spring 3 15 and spring 2 10, movement, arcuation intermediate plate 16 are finally sandwiched in round platform chamber upwards respectively
Top, arcuation intermediate plate clamp steel strand wires jointly, and elevator will not then be fallen at this time.
