Abstract

Escape device on elevator, the present invention is a field of elevator safety technology.In order to make the people of stranded elevator to save oneself, this invention takes following technical measures: cage is broadly divided into compartment top and car two large divisions and is linked together by steel wire rope, car is by the clutch of the folding and unfolding realization of steel wire rope and compartment top and realizes vertically moving of car, when car moves vertically to the elevator door of next floor immediate, captive can open elevator door escape；When having a power failure or airborne fault occurs elevator, all electromechanical equipments of elevator all cannot run well.The particularly lifting drive of elevator cannot run, and a certain position making cage can only be parked in elevator waits for rescue.But the elevator using the present invention can realize compartment top and separate with manually or electrically (accumulator is enough) of car, vertically moving of car can be realized simultaneously.When car moves vertically to the elevator door closest to floor, as long as captive is opened elevator door and just can be realized escape.

Description

Escape device on elevator

Technical field

The present invention is a field of elevator safety technology.

Background technology

The development in city is exactly that high buildings and large mansions get more and more, and installing and using of elevator is more and more universal.Elevator is a kind of Highly relying on the lowering or hoisting gear of power supply, and elevator itself is also a machinery, it is the same with all of machinery, can go out Fault.Therefore, in elevator, the events incidence of stranded several hours is more and more frequent.It is many for tracing it to its cause, except elevator Install and the most outer also have, such as, have a power failure, application maintenance is improper and mechanical breakdown etc..When Lift out of order or power failure, especially It is the lifting drive of elevator when cannot run, a certain position making cage can only be parked in elevator is waited for rescue.People Being trapped in the space of several cubic metres, four sides is steel plate, and is likely to be very dark, and people naturally can in this environment Produce dysphoria and the feared state of mind.No small torment and injury is all brought to stranded.

On the other hand, international situation upheaval today, my heart of " the super rough name for ancient tribes in the east " evil is not dead, and the probability that war breaks out more is come The biggest.Thinking of danger in times of safety, it is the target stood in the breach that war, electric power and communications facility once occur.City is once stopped Electricity, will have the stranded elevator of substantial amounts of people, have a power failure simultaneously also to rescue bring hardly possible overcome because of difficulty.Provide for a rainy day, How to escape during stranded elevator, and the escape of power supply to be independent of (electric network source), this becomes more and more important.This is the most just The starting point place of the present invention.

Summary of the invention

In order to make the people of stranded elevator to save oneself, this invention takes following technical measures: cage is broadly divided into railway carriage or compartment Top and car two large divisions linking together by steel wire rope, car passes through the clutch of the folding and unfolding realization of steel wire rope and compartment top also Realizing vertically moving of car, when car moves vertically to the elevator door of next floor immediate, captive can open elevator Door escape.

When having a power failure or airborne fault occurs elevator, all electromechanical equipments of elevator all cannot run well.Particularly electricity The lifting drive of ladder cannot run, and a certain position making cage can only be parked in elevator waits for rescue.But use this The elevator of invention can realize compartment top and separate with manually or electrically (accumulator is enough) of car, can realize hanging down of car simultaneously Translation is moved.When car moves vertically to the elevator door closest to floor, as long as captive is opened elevator door and just can be realized escaping Raw.

Accompanying drawing explanation

Escape device on Fig. 1 elevator is in front view during escape state.

Escape device on Fig. 2 elevator is in rearview during escape state.

Escape device on Fig. 3 elevator is in the front view of normal condition.

In figure: pulley 1, front cheese 2, rear cheese 3, rotating shaft 4, steel wire rope 5, car 6, fag end 7, compartment top 8, crank 9, worm gear 10, bearing block 11, worm screw 12.

Detailed description of the invention

Compartment top to be realized and car are by the way of steel wire rope links together and structure has varied, such as, can make Coordinate the mode of guide rail with wall scroll steel wire rope, or car is directly by the way of a plurality of steel wire rope with compartment top link, can be real Existing compartment top and car are linked together technique effect by steel wire rope.And above-mentioned structure and mode all can be by steel wire ropes Folding and unfolding realizes car and separates with compartment top and vertically move.

The concrete structure of this example is to realize car 6 and the link of compartment top 8 and the vertical shifting of car 6 by a plurality of steel wire rope Dynamic.This example have employed four constructions of wire rope, and they are arranged in four angles of car 6 and compartment top 8, as shown in Figure 1.Before The fag end of two steel wire ropes in face is fixed in compartment top 8, and these two steel wire ropes are wound on two respectively through after the pulley 1 of the right and left On individual front cheese 2；The fag end 7 of two steel wire ropes 5 next is fixed in compartment top 8, the other end of rear two steel wire ropes 5 rotating around After two on cheese 3.All of 4 cheeses are fixedly mounted in same rotating shaft 4, and rotating shaft 4 is installed by bearing and bearing block 11 On car 6.When axis of rotation will drive 4 cheeses to rotate 4 steel wire ropes of folding and unfolding together, it is achieved vertically moving of car； Such as: when Lift out of order or power failure, cage is parked in a certain position of elevator, up and down can not.At this moment captive Can manually or electronic form, drive shaft 4 and each cheese turning handle steel wire rope are decontroled, car 6 departs from compartment top 8 at gravity Effect under, be moved vertically downward.When car moves to the elevator door of next floor immediate, just can be opened because of person Elevator door realizes escape；When rotating shaft 4 rotates in the opposite direction, 4 cheeses can be driven equally to rotate together and to roll 4 steel wires Rope, makes car move up and combines with compartment top, continuing normal lift boy's energy.

The driving of rotating shaft 4 can use manually, it is possible to use electronic.This example is installed with worm gear 10 in rotating shaft 4, Car is provided with worm screw 12 and the crank 9 being arranged on worm screw 12.Together with worm gear 10 is ratcheting with worm screw 12.Work as captive When shaking with hands crank 9, worm screw 12 can drive worm gear 10, rotating shaft 4 to rotate together with each cheese, it is achieved the folding and unfolding of steel wire rope and sedan-chair The lifting in railway carriage or compartment；It addition, the rotating shaft 4 of this example can also be rotated by motor and actuator drives, provide escape for captive Chance.

Claims

1. the escape device on elevator, it is characterised in that: cage is broadly divided into compartment top (8) and car (6) two large divisions also Being linked together by steel wire rope (5), car (6) is by the folding and unfolding realization of steel wire rope (5) and the clutch of compartment top (8) and realizes sedan-chair Vertically moving of railway carriage or compartment (6), when car (6) moves vertically to the elevator door of next floor immediate, captive can open elevator Door escape.
