Description
Technical field
The present invention relates to vertical lift elevator technical field, a kind of safe anti-falling formula elevator is particularly belonged to.
Background technology
Elevator refers to serve some specific floors in building, and its cage operation is at least two row perpendicular to horizontal plane
Or it is less than the permanent transporting equipment of 15 ° of rigid track motion with plumb line inclination angle.Also there is step, step plate is mounted in crawler belt
Upper continuous operation, is commonly called as escalator or moving sidewalk.Serve the fixed type lifting equipment of regulation floor.Vertical lift electricity
Ladder has a car, operate at least two row it is vertical or inclination angle be less than between 15 ° of rigid guideway.Car size and knot
Configuration formula is easy to passenger to come in and go out or handling goods.No matter traditionally its type of drive, using elevator as vertical in building
The general name of transport facility.It can divide slower elevators by speed（Below 4 meter per seconds）, express lift（4~12 meter per seconds）And at a high speed
Elevator (more than 12 meter per seconds).19th century, mid-term started hydraulic elevator occur, was still applied so far on low-rise building.1852,
The E.G. Otis in the U.S. develops the safety cage of rope hoisting.The eighties, drive device has further improvement, such as electricity
Motivation drives winding reel, using balance weight etc. by worm-drive.In 19 end of the centurys, frictional wheel drive is employed, greatly increased
The hoisting depth of elevator.
20 end of the century elevators are used as power using permanent magnetic synchronous traction machine.Computer room occupation of land is greatly reduced, and with energy
Consume low, efficient energy-saving, the advantages of lifting speed is fast, greatly boosting real estate develops to Super High direction.
But existing elevator anti-fall device can only typically play the function of emergent stopping, but it is trapped in the personnel of the inside
It is difficult to save oneself, therefore it is still breakneck.
The content of the invention
It is an object of the invention to provide a kind of safe anti-falling formula elevator, the deficiencies in the prior art are overcome, in electricity
When unexpected drag rope fracture occurs in ladder, the pulling force on roller disappears, and now pressure inductor senses pressure change, starts

Moving gear case is fixed on bottom plate of connecting plate and manual gear box body is provided with rotating handles and power output gear, described
Power output gear be connected mutual transmission with gear one, described electrical brake device includes brake disc and electrodynamic braking is clamped,
Described brake disc is fixed on rotating handles, and described electrodynamic braking pincers are fixed on manual gear box body, described pressure
Power inductor signal output part and electrodynamic braking clipper joint, control it to start with closing, be additionally provided with described electrodynamic braking pincers
Remote controller.
Further, described hold-down roll is made up of the rotating wheel one and rotating wheel two of two mutual cooperations, described rotation
Runner outer shroud is provided with the notch coordinated with lead.
Further, anti-slip rubber is provided with described notch.
Further, the rotary shaft of described rotating wheel one is provided with drive one, the rotary shaft of described rotating wheel two
Provided with drive two, linked together between described drive one and drive two by transition wheel, described drive one

Further, described manual gearbox rotating handles is extended in lift car, and outside provided with dust cover.
Further, described remote controller is arranged in dust cover.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of safe anti-falling formula elevator of the present invention, when unexpected drag rope fracture occurs in elevator, on roller
Pulling force disappears, and now pressure inductor senses pressure change, starts electrodynamic braking pincers, so that limit manual gear-box rotates,
Rotated by manual gearbox, the collective effect of power output gear, gear one, hold-down roll and lead makes under elevator stops
Come, while after elevator comes to a complete stop, electrodynamic braking pincers are slowly opened using remote controller, and coordinate in manual gearbox
Rotating handles, can be such that elevator slowly declines, until the bottom, so as to so that trapped personnel can be saved with the very first time
Out, not only with good anti-drop function, and with good self-rescue function, safe and reliable, the scope of application is wide.
