A lower connecting sliding plate (4) and an upper connecting sliding plate (1) are arranged between the lower colliding plate (6) and the upper abutting plate (7), one of the lower connecting sliding plate (4) and the upper connecting sliding plate (1) is provided with a sliding groove (5), the other of the lower connecting sliding plate (4) and the upper connecting sliding plate (1) is provided with a bolt hole (2), and a bolt (8) penetrates through the bolt hole (2) and the sliding groove (5) to fasten and connect the lower connecting sliding plate (4) and the upper connecting sliding plate (1).
Description
Technical field
The present invention relates to a kind of safety device that falls, the particularly a kind of elevator cage safety device that falls.
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, when 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 to the personnel in elevator cage even three injuries of secondary.
Summary of the invention
The object of this invention is to provide a kind of elevator cage safety device 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:
The elevator cage safety device that falls, is characterized in that: under comprising, hit plate and upper follow block, hit under described between plate and upper follow block, be provided with lower connection slide plate with on be connected 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.
Under described, hit between plate and upper follow block and be also provided with the spring for cushioning.
On described lower connection slide plate, be provided with energy dissipating post.
On described upper connection slide plate, be provided with energy dissipating post.
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.

The specific embodiment
A kind of preferred embodiment of the present invention:
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4.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.
When elevator cage surprisingly drops ground, be fixed in the elevator cage safety device of elevator cage outside face base plate under hit plate 6 and first land and clashed into, 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 and to connect slide plate 1 and move downward and shear the lower energy dissipating post 9 connecting on slide plate 4, the impulsive force after elevator cage is fallen to the ground obtains actv. and alleviates or eliminate.Concerning the elevator of concrete a certain model, upper connection slide plate and lower connection slide plate arrange number, spring, energy dissipating post arrange number, determine according to the uppermost storey of elevator operation and the factors such as Maximum Loading Capacity of elevator.
