In order to solve the problem present on, people are seeking a kind of preferable technical solution always.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art, so as to provide a kind of design science, prevent used during elevator falling, peace
The high device for preventing elevator from falling of full property.
To achieve these goals, the technical solution adopted in the present invention is：A kind of device for preventing elevator from falling, including elevator
The drive system of hoistway, the elevator slided along the elevator hoistways and the driving elevator lifting, wherein, the elevator hoistways bag
The stepped track wide at the top and narrow at the bottom that four sides of correspond to the elevator respectively four are set is included, on each side of the elevator
The corresponding stepped Track desigh has telescopic elastic slide block, is set at each step of the stepped track foldable
Oblique transition face so as to the sliding block from top to bottom by the oblique transition face when can shrink, it is described tiltedly transition face pushed away by an electricity
Bar driving realizes that jack-up forms inclined-plane and folding forms plane, installation rate sensor in the elevator hoistways, controller difference
The electric putter is controlled to drive the oblique mistake when connecting the velocity sensor and the electric putter to detect velocity anomaly
Cross face folding.
Described on base, the width of each step of the stepped track is 5-10cm.
Described on base, the elastic slide block is the most long strip sliding block of longitudinal length.
Described on base, the length of stepped every section of the track is the integral multiple of lift port spacing.
It is described on base, electromagnet, the controller are set on the side of the stepped track and the corresponding elevator
Start the electromagnet when connecting the electromagnet to find velocity anomaly.
Of the invention to have prominent substantive distinguishing features and significant progress compared with the prior art, specifically, the present invention will
Elevator hoistways are designed as step-type rails, and respective carter sets elastic slide block on the four side of elevator, and elastic slide block is scalable, interior
Portion can set the elastic devices such as the stage clip of high intensity, ensure that it can be bonded with stepped track all the time, in uphill process, with
It is broadening the width of stepped track, elastic slide block also progressively stretches out；And during declining, stepped track gradually narrows, often
Oblique transition face is provided with individual step, by the extruding of oblique transition face, elastic slide block also shrinks.Sent out in whole lifting process
Life is fallen, and controller be in abnormality by velocity estimated, and the oblique transition face of control electric putter driving is folded into plane, at step
Without transition region so that elastic slide block is directly impinged upon on nearest step, plays the purpose for preventing from falling.
Further, the use of strip sliding block, it is ensured that impact strength will not also cause sliding block to deform greatly.By every section
The Design of length of track is the integral multiple of lift port spacing, coordinates with story height, the height of two to three layers of generally use, prevents
It is too high, excessive velocities.
Further, increase electromagnet, optimize jerk ability, ensure the stability of jerk.
It has the advantages of design science, prevent used during elevator falling, be safe.

Fig. 1 is the structural representation of device for preventing elevator from falling in the present invention.
In figure, 1. stepped tracks；2. elevator；3. elastic slide block；4. oblique transition face；5. velocity sensor；6. step.
Embodiment
Below by embodiment, technical scheme is described in further detail.
As shown in figure 1, a kind of device for preventing elevator from falling, including elevator hoistways, the and of elevator 2 along elevator hoistways slip
The drive system for driving the elevator 2 to lift, wherein, the elevator hoistways include four correspond to the elevator 2 respectively four
The stepped track 1 wide at the top and narrow at the bottom that side is set, the stepped track 1 is corresponded on each side of the elevator 2 and is designed with
Telescopic elastic slide block 3, folding tiltedly transition face 4 is set so as to the bullet at each step 6 of the stepped track 1
Property sliding block 3 from top to bottom by it is described tiltedly transition face 4 when can shrink, it is described tiltedly transition face 4 by an electric putter drive realize top
Rise and form inclined-plane and folding forms plane, installation rate sensor 5 in the elevator hoistways, controller connects the speed respectively
The electric putter driving tiltedly transition face is controlled to fold when sensor 5 and the electric putter are to detect velocity anomaly.Institute
The width for stating each step 6 of stepped track 1 is 10cm.The elastic slide block 3 is the most long strip sliding block of longitudinal length.
The length of every section of the stepped track 1 is 2 times of lift port spacing, i.e. two floors are high, avoids excessive height, and acceleration is too fast,
It is dangerous to hit the excessive generation of strength.
Respective carter sets elastic slide block 3 on the four side of elevator 2, and elastic slide block 3 is scalable, and inside can set high-strength
The elastic devices such as the stage clip of degree, ensure that it can be bonded with stepped track all the time, in uphill process, with stepped track 1
Width it is broadening, elastic slide block 3 also progressively stretches out；And during declining, stepped track 1 gradually narrows, and is set at each step 6
Oblique transition face 4 is equipped with, by the extruding of oblique transition face 4, elastic slide block also shrinks.
Fallen in whole lifting process, controller judges whether elevator 2 is in abnormal shape by velocity sensor 5
State, if it is, control electric putter drives oblique transition face 4 to be folded into plane, without transition region at step 6 so that elastic slide block is straight
Connect and impinge upon on nearest step 6, play the purpose for preventing from falling.
For more preferable elevating fall prevention ability, electricity is set on the side of the stepped track 1 and the corresponding elevator 2
Magnet, the controller start the electromagnet when connecting the electromagnet to find velocity anomaly.It is powered by electromagnet
The characteristic of magnetic force is obtained, for elevator tenesmus increase resistance, further strengthens the anti-fall ability of elevator.
Finally it should be noted that:The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
The embodiment of the present invention can be modified or equivalent substitution is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical scheme, it all should cover among the claimed technical scheme scope of the present invention.
