Abstract

The invention relates to elevators, in particular to a magnetic induction emergency elevator. The magnetic induction emergency elevator comprises an elevator body, a power source, a control panel, a switch and a roadway. Guide rails for allowing the elevator body to slide are arranged on the two sides of the roadway. A permanent magnet plate is arranged at the bottom of the elevator body. A buffer layer is arranged at the bottom of the permanent magnet plate. Coils are arranged on the periphery of the inner side of the roadway. The axial direction of the coils is perpendicular to the permanent magnet plate. A bottom pit of the roadway is provided with an infrared distance meter which is connected with the control panel. The coils are connected with the power source through the switch. The control panel controls the switch to be turned on and off. According to the magnetic induction emergency elevator provided by the invention, compared with passive bottom buffering of a traditional elevator, the principle is simple, implementation is convenient and rapid, a buffer function is achieved during elevator falling due to the fact that reverse acting force is generated on the elevator through magnetic fields produced by the coils, and the continuous acting force can be applied to the elevator, so that a better deceleration effect is achieved.

Description

A kind of magnetic induction emergency elevator
Technical field
The present invention relates to elevator, be specifically related to a kind of magnetic induction emergency elevator.
Background technology
Elevator is a kind of vertical conveyor being power with motor, equipped with box like gondola, takes advantage of people or carrying goods for tier building.Also having step, step plate is contained on crawler belt and runs continuously, is commonly called as escalator or moving sidewalk.Serve the fixed type lifting equipment of regulation floor.Vertical lift elevator has a car, operates between at least two rigid guideways that row are vertical or inclination angle is less than 15 °.Car size and version are easy to passenger and are come in and gone out or handling goods.No matter its type of drive traditionally, using elevator as the general name of vertical transportation means of transport in building.Slower elevators (below 1 meter per second), express lift (1~2 meter per second) and express elevator (more than 2 meter per seconds) can be divided by speed.Mid-term in 19th century starts hydraulic elevator occur, still applies on low-rise building so far.1852, the E.G. Otis of the U.S. developed the safety cage of rope hoisting.The eighties, driving device has further improvement, as motor is driven winding reel by worm-drive, adopted balance weight etc..In 19 end of the centurys, have employed frictional wheel drive, be greatly increased the hoisting depth of elevator.
Elevator employing in 20 end of the centurys permanent magnetic synchronous traction machine is as power.Being greatly reduced machine room to take up an area, and have the advantages such as energy consumption is low, efficient energy-saving, lifting speed are fast, greatly boosting real estate develops to Super High direction
Bottom fall arrest technically generally adopts, add buffer unit due to elevator of the prior art or guide rail adds braking braking system, the first situation is passive type fall arrest, the buffering effect played is faint, the damage caused is also maximum, the seized device of the second is owing to wanting and guide rail contact, owing to elevator weight is relatively big, usually rub when sinking speed is big generation spark, there is hidden danger.
Summary of the invention
The present invention provides a kind of magnetic induction emergency elevator, solves the problem that in prior art, the properly functioning middle electric current of cutoff switch causes spring aging by the heat effect caused, and concrete technical scheme is as follows:
A kind of magnetic induction emergency elevator, including elevator, power supply, panel, switch and tunnel, both sides, described tunnel are provided with the guide rail that elevator slides, and be provided with permanent magnet plate, be provided with cushion bottom described permanent magnet plate bottom described elevator, described tunnel inside circumference has coil, described coil be axially perpendicular to permanent magnet plate, the pit in described tunnel is provided with infrared range-measurement system, described infrared range-measurement system connect described panel, described coil connects power supply by switching, and described panel controls switch on and off.
Further, described coil turn is gradually increased from top to bottom.
Further, described permanent magnet plate thickness is 10cm.
Further, described elevator is additionally provided with gravity sensor, and described gravity sensor is connected with panel signal.
Further, described cushion is foam.
Further, described buffer layer thickness is 30-50cm.
It should be noted that, the present invention utilizes infrared range-measurement system to gather the elevator distance to pit, and convert the signal of telecommunication to panel, when elevator drop to set height position, now panel controls switch motion, power supply is to coil power supply, now coil can produce a magnetic field, permanent magnet plate bottom elevator is played active force upwards by this magnetic field, for elevator being played deceleration buffer effect, decline along with elevator, coil turn is increasing, the active force produced is also more big, accidental falling for elevator has good cushioning effect, simultaneously, add gravity sensor as dual fail-safe, prevent the detection failure that single sensor degradation causes.
Beneficial effect:
The present invention provides a kind of magnetic induction emergency elevator, cushion relative to bottom the passive type of traditional elevator, principle is simple, implement convenient and swift, cushioning effect is played when elevator is produced opposition to used during elevator falling in the magnetic field produced by coil, can be applied on elevator by lasting active force, there is better slowing effect.
