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 roller elevator anti-fall device, the deficiencies in the prior art are overcome, mainly
Using with vertical lift elevator or box-type boom hoisting, when there is the fracture of unexpected drag rope in lift car, roller
On pulling force disappear, now pressure inductor senses pressure change, starts electrodynamic braking pincers, so that limit manual gear-box revolves
Turn, rotated by manual gearbox, the collective effect of power output gear, gear one, hold-down roll and lead stops elevator
Stop and, while after elevator comes to a complete stop, electrodynamic braking pincers are slowly opened using remote controller, and coordinate manual gearbox
On rotating handles, elevator can be made slowly to decline along two side leads, Stability Analysis of Structures is safe and reliable, applied widely
It is wealthy.
To solve the above problems, the technical solution used in the present invention is as follows：
A kind of roller elevator anti-fall device, including bottom plate of connecting plate, manual gearbox, electrical brake device and two sides are oriented to
Post, two described side leads are vertically-mounted, are provided with the middle of described bottom plate of connecting plate by support on roller, described support
Provided with the waist hole up and down coordinated with roller rotary shaft, it is provided with above described waist hole on pressure inductor, described connecting bottom board
Two side positions, which are equipped between the hold-down roll coordinated with lead, two described side hold-down rolls, passes through rotary shaft and shaft coupling
Link together and rotary shaft is provided with gear one, described manual gearbox is fixed on bottom plate of connecting plate and manual gear
Box body is provided with rotating handles and power output gear, and described power output gear is connected mutual transmission, institute with gear one
The electrical brake device stated includes brake disc and electrodynamic braking is clamped, and described brake disc is fixed on rotating handles, described electricity
Dynamic caliper is fixed on manual gear box body, described pressure inductor signal output part and electrodynamic braking clipper joint, control
Make it to start with closing, remote controller is additionally provided with described electrodynamic braking pincers.
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
By belt transmission between transition wheel, gear drive is passed through between described transition wheel and drive two.
Further, described lead includes two vertical cylindrical tubes and two vertical cylindrical tubes links together
Several connecting rods.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of roller elevator anti-fall device of the present invention, main application and vertical lift elevator or box-type boom hoisting
On, when unexpected drag rope fracture occurs in lift car, the pulling force on roller disappears, and now pressure inductor senses pressure
Power change, start electrodynamic braking pincers so that limit manual gear-box rotate, rotated by manual gearbox, power output gear,
The collective effect of gear one, hold-down roll and lead stops elevator, while after elevator comes to a complete stop, utilizing remote control control
Device processed slowly opens electrodynamic braking pincers, and coordinates the rotating handles in manual gearbox, and elevator can be made to be oriented to along two sides
Post slowly declines, Stability Analysis of Structures, safe and reliable, and the scope of application is wide.
