Abstract

Provided is a magnetic suspension resistance type elevator. According to the magnetic suspension resistance type elevator, the magnetic suspension resistance type elevator and electromagnetic materials are combined. According to a system, vertical movement of the magnetic suspension resistance type elevator serves as magnetic induction line cutting movement. In the system, the whole elevator hoistway can become an annular multi-ring coil, magnetic substances can be installed on an elevator body, when the annular multi-ring coil is energized, perpendicularly-upward acting force can be provided for the magnetic suspension resistance type elevator, and the magnetic suspension resistance type elevator moves upwards. Acting force borne by the magnetic suspension resistance type elevator is controlled through control over electric current. When the magnetic suspension resistance type elevator descends, the magnetic suspension resistance type elevator carries out the magnetic induction line cutting movement through gravity, gravitational potential energy can be converted into electric energy, the electric energy is stored in a switching type capacitor, the capacitor carries out saturated discharging to generate reverse current, and the magnetic suspension resistance type elevator decelerates due to opposite force. The system can save energy, and can prevent emergencies from occurring through the advantages of the system, when the magnetic suspension resistance type elevator is in emergency, the magnetic suspension resistance type elevator can carry out independent operation, and safety of passengers is ensured.

Description

Magnetic floats resistance type elevator

Technical field:

Elevator, escape, electromagnetism, pulls system

Background technology:

Elevator is the instrument that current popularization degree is quite high, has become one of main instrument of current people's trip.By technology in the past, what the lifting of elevator was used is that the straight line that pulls formula rises, or the oblique line of roller type rises, be all to using electrical motor to carry out linearity transmission as passing spindle, the system of pulling can be described as the core apparatus of whole elevator, pulling system and electric-control system is two cores of lift appliance, from security standpoint, the system that pulls is again that the most important thing wherein, especially elevator are as a kind of device of frequent use, its degree of aging and quality problem are potential harm always.From pulling the electrical motor of formula, it uses the size of power and the life-span that load weight has determined elevator, the product of all knowing load weight and speed just equals power, that is to say, load is heavier, the operating power of electrical motor will quota so, every sample product all can have the possibility of et out of order in so maximum used time limit, once because electrical motor et out of order this elevator cocktail party is instantaneous so loses propulsive effort and do the movement of falling object, the direct result of this motion is exactly that elevator is along with all loadings together become pulverizing, this is that we are least ready to see.They are two years old, how, even if the stable electronic instrument that pulls, meets the destruction that an earthquake or floor meet with external strong again, can not avoid so too the generation of the movement of falling object, this is that condition by type of drive device is limited, the obstacle under prior art condition basis.

Summary of the invention:

According to above existing elevator drive modes, avoid elevator because of accident aging or that external force obstacle causes, unique method makes elevator have autonomous option right exactly.This is a more humane address, is exactly in fact to allow elevator can fall into stratum with a quite low sinking speed in complete out of control situation.This means that elevator can depart from floor and enter self-mode of operation.For this reason, the solution of using electromagnetic technique to carry out the method has the breakthrough of epoch, and magnetic field can utilize and the auxiliary strength of conduct.The load of using magnetic suspension to be used as elevator as the drag devices of elevator is accepted body and is necessary, because the in the situation that of power-off, magnet material still can be done cutting magnetic induction line motion in the coil device of a sealing, and this certainly will form a reverse pulling force.When elevator loses after the effect that pulls device, neither one is external can overcome terrestrial gravitation, and at this time pole winding will play a role, they will produce a reversal interlocking relay resisting with terrestrial gravitation, and this power is along with size and the speed of gravitation have proportional relation, no matter gravitational size, all can overcome, so under the effect of electromagnetic induction, elevator can land with a comparatively safe speed.Moreover, because electromagnetic induction has the effect underspeeding, so when elevator is done downward movement, can produce a resistance making progress, this all does work and compares with up-and-down movement in traditional elevator, and this resistance can make the use power of elevator reduce greatly, plays energy-conservation effect.

The specific embodiment:

At elevator, go straight up to the vertical many ring coils that install a ring-type in passage additional, the power of coil must be set according to institute in load, then elevator hanging basket is carried rectifying and become magnetic substance, like this, at wound coil place, add a forward current, at this time elevator will have along with magnetic substance the effect of the power making progress, when this strength is greater than after terrestrial gravitation, elevator can be done acceleration upward movement, controls the operative condition of elevator by controlling the size of electric current.A suitching type C/LOOP and savings electric capacity are installed in these devices, this device will be controlled the downstream state of elevator, under the effect of gravity, elevator moves downward, and in motion, gravitional force is converted into electric energy, these electric energy are saved automatically to electric capacity, back discharge when capacitor charging is full, produces counter-current, and this galvanic action will produce a reciprocal power in pole winding, this power balances out the effect of gravity, and elevator is done decelerated movement.

Claims (2)

1. make to using electromagnetic force as an elevator traffic instrument for propulsive effort, it is characterized in that: the closing coil of ring more than is installed in access to elevators, and elevator is installed magnet material becomes a load magnet.When electric current passes through coil, the stressed upward movement of elevator; When elevator is done downward movement, gravity acting, gravitional force converts electric energy in magnetic field, and electric energy is stored in a switching type capacitor, and the saturated electric discharge of electric capacity produces counter-current, produces opposite force, deceleration of elevator.

2. according to (1) magnetic lift appliance of tool of claim, its hoist trunk covers many ring closing coils, and elevator will be realized the ability of up-and-down movement by electromagnetic induction power.(2) capacitive means, encircle closing coil with passage more and combine, for storing the electric energy producing because of galvanomagnetic effect, this electric energy has particularity, and when speed of moving body is large, electric weight is just large, when reaching a punching voltage, electric capacity automatic discharging, produces counter-current.This electric current acting in opposition, on coil, produces counter-current, and coil produces opposition, and elevator is played to deceleration effort.
