Background technology
Along with social development, in city, skyscraper is more and more, and elevator is absolutely necessary as a kind of vertical transportation instrument.Elevator, in bringing convenience to people, also brings many potential safety hazards to people, particularly when elevator breaks down directly from aerial Crater face, cause fatal harm can to the personnel in elevator cage.In prior art, the patent of China Patent No. 201210384501.5 provides a kind of elevator cage shock absorber,, in elevator bottom and elevator, shock absorber is installed, its weak point is that the waste of power of elevator cage tenesmus is few, can cause even three injuries of secondary to the personnel in elevator cage.
Summary of the invention
The object of this invention is to provide a kind of elevator cage safety guard that falls, it can make elevator cage from falling ground in the air, can effectively alleviate and even avoid personnel in elevator cage to come to harm.
Task of the present invention completes in the following way:
A kind of elevator cage safety guard that falls, under comprising, hit the fender guard that safety device, energy-dissipation net framework and energy-dissipation net that plate and upper follow block form form, it is characterized in that: under safety device, hit and between plate and upper follow block, be provided with lower connection slide plate and upper connection slide plate, on one of them plate of described lower connection slide plate and upper connection slide plate, be provided with chute, on another plate, be provided with bolt hole, bolt passing through bolt hole and chute tighten up lower connection slide plate and upper connection slide plate to be connected together, and upper follow block is fixed on the base plate of elevator cage outside face; On the energy-dissipation net framework of fender guard, be fixedly installed energy-dissipation net, energy-dissipation net framework is arranged on elevator bottom.
Under described safety device, hit between plate and upper follow block and be also provided with spring.
On described lower connection slide plate, be provided with energy dissipating post.
The shaft bottom of described fender guard is provided with ground recoil spring.
Owing to having adopted such scheme, the present invention can make elevator cage from falling ground in the air, can effectively alleviate and even avoid personnel in elevator cage to come to harm.
Accompanying drawing explanation
Fig. 1 is the structural representation of safety device of the present invention.
Fig. 2 is the vertical section structure schematic diagram of fender guard of the present invention.
In figure, each symbol represents:
1, upper connection slide plate 2, bolt hole 3, energy dissipating post jack 4, lower connection slide plate 5, chute 6, under hit plate 7, upper follow block 8, bolt 9, energy dissipating post 10, spring 11, energy-dissipation net framework 12, energy-dissipation net cruciform bracing 13, fixed orifice 14, energy-dissipation net 15, shaft bottom 16, ground recoil spring
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5.In Fig. 1, on upper connection slide plate 1, be provided with bolt hole 2 and energy dissipating post jack 3.In Fig. 2, on lower connection slide plate 4, be provided with energy dissipating post jack 3, chute 5.In Fig. 3, when upper connection slide plate 1 with under be connected slide plate 4 use bolt passing through bolt hole 2, chute 5 by upper connection slide plate 1 with under be connected slide plate 4 and tighten up and be connected after, if lower connection slide plate 4 is subject to after impact, inevitable upward movement is sheared the energy dissipating post on the energy dissipating post jack 3 that is fixed on connection slide plate 1; Upper connection slide plate 1 carries out energy dissipating to the energy dissipating post being fixed on energy dissipating post jack 3 connecting on slide plate 4 under down cut under Action of Gravity Field, and the impulsive force after elevator cage is fallen earthward obtains actv. and alleviates or eliminate.In Fig. 4, upper follow block 7 is securely fixed on the base plate of elevator cage outside face.Under hit and between plate 6 and upper follow block 7, be provided with connection slide plate 1 and lower connection slide plate 4.Upper connection slide plate 1 one end is fixed on follow block 7, and lower connection slide plate 4 one end are fixed on down hits on plate 6.Bolt 8 tightens up upper connection slide plate 1 and lower connection slide plate 4 to be connected together through the chute 5 of the bolt hole 2 on upper connection slide plate 1 and lower connection slide plate 4.On the energy dissipating post jack 3 of upper connection slide plate 1 and lower connection slide plate 4, be provided with energy dissipating post 9.Under hit between plate 6 and upper follow block 7 and be also provided with spring 10, to make impact obtain certain buffering.
In Fig. 5, on energy-dissipation net framework 11, be fixedly installed energy-dissipation net cruciform bracing 12, on energy-dissipation net cruciform bracing 12, be provided with fixed orifice 13.Energy-dissipation net 14 is fixed in the fixed orifice 13 on energy-dissipation net cruciform bracing 12.Energy-dissipation net framework 11 adopts expansion bolt to be fixedly installed on the bottom surface of elevator bottom and the metope of surrounding.In the shaft bottom 15 of energy-dissipation net framework 11 bottoms, be fixedly installed ground recoil spring 16.
When unexpected tenesmus earthward appears in elevator cage, tenesmus was by the energy-dissipation net of the energy dissipating framework 11 of elevator cage fender guard 14 o'clock, be fixed in the elevator cage safety device of elevator cage outside face base plate under hit plate 6 and first clash into ground floor energy-dissipation net 14, upwards promote lower slide plate 4 upward movements that connect and shear the upper energy dissipating post 9 connecting on slide plate 1, upper follow block 7 moves downward Compress Spring 10 under Action of Gravity Field, and drive the upper slide plate 1 that connects to move downward the lower energy dissipating post 9 connecting on slide plate 4 of shearing, impulsive force after elevator cage is fallen to the ground obtains actv. and alleviates or eliminate, simultaneously, when elevator cage is pounded to elevator bottom from falling from high altitude, first the elevator cage safety device that is fixed on elevator cage bottom is pounded to the ground floor energy-dissipation net 14 on the energy-dissipation net framework 11 of elevator cage fender guard, ground floor energy-dissipation net 14 is cut off and by elevator cage energy dissipating, drop to again on second layer energy-dissipation net 14, second layer energy-dissipation net 14 is cut off and by elevator cage energy dissipating, like this like, until set energy-dissipation net 14 is all cut off, finally by the further energy dissipating of ground recoil spring 16, make elevator cage realize its soft landing, even avoid personnel in elevator cage to come to harm thereby effectively alleviate.
