It is the minimal structure ultimate principle figure of upper and lower two groups of magnets as shown in Figure 1 and Figure 2, two magnet gaps are equipped with, When two magnets are mutually coupled completely, the normal direction magnetic attraction for producing between the two（When two magnet polarities are contrary）Or normal direction repulsive force （When two magnet polarities are identical）Maximum, gradually decreases both or increases coupling area when one of which magnet is vertically moved, then Normal direction magnetic force is gradually reduced or increases between the two, during this, from normal direction maximum magnetic attraction position to normal direction maximum repulsive force It is subject to simultaneously to attempt to hinder acting on for mobile reluctance force in the longitudinal movement of position, conversely, during reverse return By by helping acting on for the magnetic restoring force for resetting.Move one of them to control the area that intercouples by low-force, so that it may To control the normal direction magnetic attraction or normal direction repulsive force of numerically big several times.Gap between the two is with magnetic attraction or repulsive force in just Feedback relationship, gap are less, and magnetic force is bigger；Conversely, gap is bigger, magnetic force is less.Fig. 2 is upper and lower two groups between magnet and stator The ultimate principle figure that gap coordinates, stator are at least made up of one group of fluting or the iron core do not slotted, and upper and lower two groups of magnet polarities are contrary And when when coupling completely, normal direction magnetic attraction between the two is maximum, the second magnet is less to the coupled magnetic field of stator, conversely, upper, When lower two groups of magnet polarities are identical and normal direction repulsive force when coupling completely between the two is maximum, coupling of second magnet to stator Magnetic field is bigger.

As shown in Fig. 3 ~ Fig. 8, dynamic magnetic level is at least arranged in order with the second iron core by one group of second magnet and is formed, and compound level is extremely Few being arranged in order with the first iron core by one group of first magnet is formed, and both gaps coordinate, and dynamic magnetic level may be alternatively located at one with compound level The side of individual stator is located between two stators, the ultimate principle figure that gap between them coordinates.In figure, move magnetic level and be combined In level, the centre-to-centre spacing of arbitrary neighborhood magnet or iron core is equal for t, when the first magnet is overlapped with the centrage of the second magnet, if the First, the polarity of the second magnet is identical, moves, if opposite polarity, both it Between produce magnetic attraction for maximum, by move back and forth wherein move magnetic level make magnetic force gradually with t/2 ~ t distance in compound level Become maximum or minimum, during this, also can be acted on by magnetic restoring force that Fig. 1 is similar to and reluctance force, when by opening a way to short Line state movement is magnetic restoring force（Help is moved）, when by being short-circuited to open-circuit condition movement for reluctance force（Hinder movement）, essence On see it is that magnetic circuit is always attempted in itself to return upper and lower magnet and coupled completely and opposite polarity maximum magnetic flux suction force state.Fig. 5 and Tu In shown in 8, magnetic level is moved and the primary that compound level is permanent-magnet linear flux switching motor, if its motion is also referred to as mover, stator For the secondary of permanent-magnet linear flux switching motor（It is made up of grooved core）, move magnetic level or compound level is equipped with stator, when Dynamic magnetic level is in " open-circuit condition " with compound level（When i.e. upper and lower polarity identical magnet center line overlaps）, move magnetic level and be combined Between level repulsive force be maximum, the magnetic attraction between stator and dynamic magnetic level or compound level be maximum, maximum magnetic repulsion value is reachable （Or exceed）The half of maximum magnetic attraction, during mobile t/2（Between open circuit and short circuit）Its value for magnetic attraction being subject to also surpasses Cross the half of maximum magnetic attraction, permanent magnetic field mainly acts on stator and the dynamic magnetic level that coordinates with which or compound level between, now, Stator and the dynamic magnetic level or compound level that coordinate with which have become the permanent-magnet linear flux switching motor of a normal work.When Dynamic magnetic level is in " short-circuit condition " with compound level（I.e. upper and lower two opposite polarity magnet center lines overlap）When, move magnetic level with Between compound level, magnetic attraction is maximum, and the magnetic attraction between stator and the dynamic magnetic level coordinated with which or compound level is minimum, only Between the dynamic magnetic level or compound level that sub-fraction the action of a magnetic field coordinates in stator and with which is determined, as permanent-magnet linear switch flux-linkage electricity Machine is less using function limitation, electromagnetic push；Gap between dynamic magnetic level and compound level is in positive feedback with magnetic attraction or repulsive force Relation, gap are less, and both magnetic force are bigger；Conversely, gap is bigger, magnetic force is less.In shown in Fig. 4 and Fig. 7, permanent-magnet linear is The secondary of salient-pole machine, is at least arranged in order with iron core by one group of magnet and is formed；In shown in Fig. 1 ~ Fig. 3, Fig. 6, move magnetic level and answer Close a secondary for permanent-magnet linear salient-pole machine in level, another primary for permanent-magnet linear flux switching motor.Substantially it is former Reason is ibid.Wherein, move magnetic level and compound level is located between two stators and gap coordinates composition bilateral linear motor.

Described magnet is constituted for monolithic magnet or one group of magnet, or polylith magnet that is identical by polarity or differing, such as Halbach magnet arrays.Magnet is the magnetic materials such as permanent magnet, electrical excitation body, superconducting magnet.

According to above-mentioned principle, make deadman's brake and suit somebody to a T.If compound level and dynamic magnetic level normal direction flying height Coordinate, longitudinal sliding motion is secondary to be coordinated, and in both compound level and dynamic magnetic level is braked with least one frictional damping mechanism Block or brake arm are connected, and another drives little stroke to move back and forth by itself or external force, it is possible to control normal gap, method Gradually increase or be gradually reduced the steady closure or opening function of realizing brake to power.

Using above-mentioned principle, tripping spring can also be used cooperatively together with permanent magnetism, is applied or is released brake force simultaneously Carry out " mixing（Dual force）Braking is opened ", the security reliability of brake is further guaranteed with purely mechanic mode of braking：Braking Spring force can overcome tripping spring power to open brake, magnetic using above-mentioned repulsive force by can at least brake nominal load design Suction is used for closing（Band-type brake）, mobile 1/2 stroke magnetic attraction can exceed the half of maximum braking force, if 2 times of brakes Multiple（Safety coefficient）, lock has now been embraced, complete stroke has been continued to move to, is reached maximum braking force.

With reference to Figure 17 ~ 28 and Figure 29 ~ 34, the permanent magnetism of 38 ~ 40 explanations utilization linear electric motors of the present utility model itself The straight drive elevator of normal force and lifting force as brake driving force（Elevator）Braking operation process：

, used as special equipment, brake generally requires two sets of setting for elevator or elevator, is located on A section movers and arranges braking Device A, arranges brake B on B section movers.It is directed to two kinds of structural principles separately below to describe.

First, it is combined the subunit slip setting that level flying height is arranged, coordinated with which

Service braking（From being opened to on-position）：Driver controller controls elevator orderly shutdown（0 speed）, keep A Section mover is powered and lifts car, and brake A continues to open, and then controls the subunit that B section movers make to coordinate with compound level A A is moved down, and makes compound level A from open-circuit condition gradually to short-circuit condition transition, the Normal Force being combined between level A and subunit A Gradually increase, when the little pretightning force of the returning spring secondary more than floating guiding, returning spring is compressed, subunit A with Gap between compound level A reduces rapidly, and brake brake disc starts to embrace guide rail（Now, because of normal force and less, band-type brake power compared with It is little）, afterwards, subunit A continues to fall, and when falling instantly bottom spacing place, is combined level and enters dead short state, be combined level Normal Force between A and subunit A is maximum, realizes brake B maximum dynamic brakings, then controls A sections mover whereabouts again To bottom spacing place, brake A is closed completely, realizes service braking.

Work is opened（From braking to open mode）：Drive control device control A sections mover is first powered to producing and lifts enough The lifting force of car, is moved at upper limit or is close at upper limit on the subunit A coordinated with compound level A, and brake A beats Open, in opening procedure, level A is combined from short-circuit condition gradually to open-circuit condition transition, is combined between level A and subunit A Normal Force is gradually reduced, and when the little pretightning force of the returning spring secondary less than floating guiding, brake is in returning spring Effect is lower to open（Declutch）, now, above move on at about the 2/3 of total kilometres, because returning spring restoring force it is less, this declutch power also compared with Little, with moving at upper limit in subunit A continuation, the gap between subunit A and compound level A increases to maximum, braking Device brake disc is declutched completely, is then controlled the energization of B sections mover again and is produced lifting force opening brake B, realizes that brake operation is opened With elevator normal hoisting.

2nd, it is combined the setting of level floating glade plane space, subunit to be connected with mover beam or car frame or car

Service braking（From being opened to on-position）：Driver controller（An elevator driving controller can be shared, need not Special drive control device, power source special are set separately）Control elevator orderly shutdown（Zero velocity）, keep A, B section mover to be powered and lift Car, mover（Including subunit A, B）, mover beam and back-shaped beam remain static, then, drive control device is gradually reduced Electromagnetic force is lifted in hovering, when less than deadweight, back-moving spring and magnetic restoring force, when making a concerted effort, compound level A, B is in back-moving spring and magnetic Back-shaped beam on edge is moved under restoring force collective effect upwards gradually, the method being combined between level A, B and corresponding subunit A, B Gradually increase to suction, brake A, B closure realizes service braking.

Work is opened（From braking to open mode）：Drive control device（An elevator driving controller can be shared, without the need for another If special drive control device, power source special）Control A, B section mover is first powered to producing and lifts mover beam, car frame and sedan-chair enough The lifting force in railway carriage or compartment, then drives mover beam, mover with setting speed（Including subunit A, B）, move to compound level on back-shaped beam The bottom of A, B is close to the bottom for being combined level A, B, and compound Normal Force between level A, B and corresponding subunit A, B is gradually Reduce, brake A, B are opened, realize that brake operation is opened and elevator normal hoisting.

The brake of above-mentioned two class normally open or Operating In Persistent Current Mode during, it is shorter to carry or move down stroke on mover, typically exists Tens millimeters（Such as 10-50mm）Within, only quite with ordinary electromagnetic formula deadman's brake in electric magnet impulse stroke.

In the case of accident power-off, mover is in the case where deadweight, back-moving spring and larger magnetic restoring force make a concerted effort collective effect with several times Acceleration of gravity falls rapidly, primary Calculation, and mover falls（That is brake）Time is a few tens of milliseconds（Such as 40ms）Within, The distance of glide of car is less than 7mm, and gliding speed is less than 0.37m/s, if consider to slip down to about 2/3 stroke, brake system Power has been maxed out the 50% of brake force, from appropriate design angle, by twice brake force safe clearance, now has been able to Car is braked, distance of glide and speed are less, speed of action is set much smaller than safety tongs（When beyond the specified operation of car 10% ability action of speed, the specified speed of service of general load-carrying 800kg above elevators is in 1 ~ more than 2.5m/s）, it is sufficient to ensure sedan-chair Railway carriage or compartment and personal security.

In lifting process, lifting force is not enough or in the case of running out of steam：Due to subunit A, B be and meanwhile with other movers Unit undertakes together and lifts load, either subunit A, B, or other any group ofs or multigroup subunit, occurs Lifting force not enough or the situation that runs out of steam, as long as the load that the subunit of remaining work bears is without departing from the maximum that can be born Lifting force（Generally 1.5 ~ 2 times specified lifting forces）, continue to by system control, once exceed maximum bearing ability, straight-line electric Machine step-out, no matter system whether send out band-type brake instruction, mover under deadweight, back-moving spring and magnetic restoring force force action, Jiu Huiji Shi Zidong implements lifting force disappearance " self-protection " safety arrestment, fundamentally ensure that elevator（Elevator）Real time security And reliability, it is to avoid the indiscriminate dynamic of safety tongs mandatory reserve protection, frequency are dynamic, malfunction causes clamp to produce with braking rail to break Bad property, severe impact, friction, vibrations, stop transport the maintenance even generation of the severe safety accident such as personal injury.

Above-described embodiment only to illustrate technology design of the present utility model and feature, its object is to allow and be familiar with technique Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this. All equivalence changes made according to this utility model spirit or modification, should all cover protection domain of the present utility model it It is interior.
