Specific embodiment
Elaboration is further made to the present invention with reference to the accompanying drawings and examples.
It is as shown in Figure 1 and Figure 2 one group of magnet for dynamic magnetic grade, composite plate is the minimal structure basic principle of one group of magnetic conductive board Figure, magnet and magnetic conductive board fit clearance are arranged, when magnetic conductive board mutually couples (referred to as short-circuit condition) with magnet completely, the two it Between the normal direction magnetic attraction that generates it is maximum, when longitudinal movement magnet or magnetic conductive board both make to gradually decrease coupling area (not coupling completely Close, referred to as open-circuit condition), then normal direction magnetic attraction is gradually decrease to zero between the two, will be same in longitudinal movement direction during this When by the effect for attempting to hinder mobile, opposite reluctance force, reluctance force of this reluctance force under short circuit and open-circuit condition is zero, It is the maximum (1/5-1/ of the general only maximum normal force of maximum reluctance force that this reluctance force has just been left near magnet positions in magnetic conductive board 10 or less) it, is gradually decreased as zero later.At this point, making the two gradually increase coupling area when reversed return is mobile, then between the two Normal direction magnetic attraction is gradually increased to maximum, will be resetted referred to as magnetic restoring force by a kind of help simultaneously during reversed return Effect, this magnetic restoring force and reluctance force it is equal in magnitude, direction is identical, that is to say, that by similar in reciprocating movement In the effect of the power of spring, forward direction is resistance, is reversed reply pulling force, substantially sees it is that magnetic circuit itself always attempts to keep in the center (magnetic circuit couples completely, the smallest maximum magnetic flux suction force state of magnetic resistance).Phase is controlled by the mobile composite plate of low-force or dynamic magnetic grade Mutual coupling area, so that it may control the normal direction magnetic attraction of numerically big several times.Both composite plate and dynamic magnetic grade gap and magnetic attraction It is positive feedback effect relationship, gap is smaller, and the two magnetic attraction is bigger;Conversely, gap is bigger, magnetic attraction is smaller.
It is at least arranged successively by one group of magnet with iron core as Fig. 3 ~ Fig. 4 show dynamic magnetic grade, composite plate is led by one group Magnetic sheet is arranged successively with non-magnetic plate, moves basic schematic diagram of the magnetic grade between composite plate and stator.In Fig. 3, stator At least be made of one group of winding and grooved core, the center of two permeability magnetic material of arbitrary neighborhood of composite plate or non-magnet material away from The center of dynamic two magnet of magnetic grade arbitrary neighborhood away from it is equal be t, when the center of composite plate permeability magnetic material away from in dynamic magnetic grade magnet When the heart is away from being overlapped, magnetic attraction is maximum between the two for composite plate and dynamic magnetic grade, and stator is with dynamic magnetic grade that magnetic attraction is between the two It is minimum;When the center of composite plate non-magnet material with the center line of dynamic magnetic grade magnet away from being overlapped, both composite plate and dynamic magnetic grade Between magnetic attraction be minimum, and magnetic attraction is maximum between the two for stator and dynamic magnetic grade;By moving back and forth composite plate or dynamic magnetic A t/2 distance in grade makes magnetic attraction gradually become maximum or minimum, during this, also will receive the similar magnetic of Fig. 1 and replys The effect of power and reluctance force.In shown in the upper figure of Fig. 3, the primary that magnetic grade is permanent-magnet linear flux switching motor is moved, if it is moved Referred to as mover, stator are the secondary (grooved core) of permanent-magnet linear flux switching motor, and dynamic magnetic grade is equipped with stator, multiple Plywood is in short-circuit condition (i.e. magnet center line is overlapped with magnetic conductive board center line), at this point, permanent magnetic field mainly act on it is compound Between plate and dynamic magnetic grade, magnetic attraction is maximum between the two for composite plate and dynamic magnetic grade, stator and dynamic magnetic grade magnetic attraction between the two For minimum, only sub-fraction magnetic fields in stator and dynamic magnetic grade between the two, make as permanent-magnet linear flux switching motor Smaller with contributing, electric motors function is limited;In shown in Fig. 3 following figure, composite plate is in open-circuit condition, i.e., magnet center line with it is non-magnetic Plate center line is overlapped, at this point, magnetic attraction is close to zero between the two for minimum for composite plate and dynamic magnetic grade, permanent magnetic field main function In dynamic magnetic grade and stator, magnetic attraction is maximum between the two for stator and dynamic magnetic grade, at this point, if the winding of dynamic magnetic grade is powered, stator Have become the permanent-magnet linear flux switching motor of a normal work with dynamic magnetic grade.Composite plate and dynamic magnetic grade between the two between Gap and magnetic attraction are positive feedback effect relationships, i.e., gap is smaller between the two with dynamic magnetic grade for composite plate, and magnetic attraction is bigger;Conversely, Gap is bigger, and magnetic attraction is smaller, and stator gradually changes into the permanent-magnet linear flux switching motor of normal output with dynamic magnetic grade.
In shown in Fig. 4, the secondary that magnetic grade is permanent-magnet linear salient-pole machine is moved, is at least arranged successively by one group of magnet with noseiron It forms, because collateral motion is also referred to as mover, composite plate is arranged successively by one group of magnetic conductive board with non-magnetic plate, and stator is The primary of permanent-magnet linear salient-pole machine is at least made of one group of winding and grooved core, and composite plate is that one group of magnetic conductive board is led with non- The assembly that magnetic sheet is arranged successively moves basic schematic diagram of the magnetic grade between composite plate and stator.In the upper figure of Fig. 4, composite plate In short-circuit condition, i.e. magnet center line is overlapped with permeability magnetic material center line;In Fig. 4 following figure, composite plate is in open-circuit condition, i.e., Magnet center line is overlapped with non-magnet material center line.Remaining same Fig. 1-Fig. 2.
Above-mentioned magnet is monolithic magnet or one group of magnet, or identical by polarity or different muti-piece magnet forms, such as Halbach magnet array.Magnet is the magnetic materials such as permanent magnet, electrical excitation body, superconducting magnet.
According to above-mentioned principle, three dynamic magnetic grade/composite plates are set and is made into deadman's brake and suits somebody to a T: setting three Dynamic magnetic grade or two dynamic magnetic grades and a composite plate or two composite plates and a dynamic magnetic grade, the mutual clearance fit of three, and make One in three and other two (along longitudinal direction) arranged in dislocation, so that the normal force and magnetic field between three are one side enhancing (maximum), in addition on one side weaken (minimum), or on one side for attraction, in addition while be repulsive force, therefore, by one in three Or two composite plates (13) or dynamic magnetic grade (12) are connected at least one friction catch mechanism brake block or brake arm, in addition two It is a or one is moved back and forth by the small stroke of itself or outer power drive, so that it may to control normal gap, normal force is gradually increased Or be gradually reduced and realize that the steady of brake closes or opens function, two dynamic magnetic grade/composite plates are separately provided in stopping power ratio It is eager to excel much bigger (at least one times strong), control characteristic is also more flexible.As shown in Fig. 5 ~ Fig. 6.
Magnetic grade/composite plate principle is moved using above three, can also simultaneously be used cooperatively tripping spring together with permanent magnetism, Apply or release brake force and carry out " mixing (dual force) braking or opening ", further ensures that brake is pacified with purely mechanic mode of braking Complete reliable braking: tripping spring power can be made every effort to overcome by can at least brake nominal load design using the repulsive force or attraction on one side System of mourning spring force of moving opens brake, after displacement, is used to be closed together using the magnetic attraction and tripping spring on other one side and (embrace Lock), have brake force superpower, the remarkable advantage that required opening force is small, safe and reliable.

Illustrate the permanent magnetism normal force of the invention using linear motor itself below with reference to Figure 15 ~ 16 and Figure 18 ~ 21 and mentions Braking operation process of the lift as the cordless elevator (elevator) of brake driving force:
As special equipment, brake generally requires two sets of setting for elevator or elevator, is located on A sections of movers and braking is arranged Brake B is arranged in device A on B sections of movers.It is described separately below for two kinds of structural principles.
One, it floats, sliding is provided separately
Service braking (from on-position is opened to): driver controller controls elevator orderly shutdown (0 speed), keeps A Carriage is lifted in section mover energization, and brake A continues to open, and then controlling B sections of movers makes the subunit cooperated with composite plate A A is moved down, and makes composite plate A from the open-circuit condition gradually Normal Force to short-circuit condition transition, between composite plate A and subunit A Be gradually increased, when being greater than the little pretightning force of returning spring of floating guiding pair, returning spring is compressed, subunit A and Gap between composite plate A is reduced rapidly, brake brake disc start to embrace guide rail (at this point, because of normal force and little, band-type brake power compared with It is small), later, subunit A continues to fall, and when falling on bottom spacing place instantly, composite plate enters dead short state, composite plate Normal Force between A and subunit A is maximum, realizes brake B maximum dynamic braking, then controls A sections of movers again and falls To bottom spacing place, brake A is closed completely, and realizes service braking.
Work is opened (from braking to opening state): drive control device A sections of movers of control are first powered to generating to be lifted enough The lifting force of carriage moves up supreme spacing place with the subunit A of composite plate A cooperation or close at upper limit, brake A is beaten Open, in opening procedure, composite plate A from short-circuit condition gradually to open-circuit condition transition, between composite plate A and subunit A Normal Force is gradually reduced, and when the little pretightning force of the returning spring for being less than floating guiding pair, brake is in returning spring Effect is lower to open (declutching), at this point, this power that declutches is also smaller because returning spring restoring force is smaller, continue with subunit A on It moves at upper limit, the gap between subunit A and composite plate A increases to maximum, and brake brake disc declutches completely, then controls again B sections of mover processed, which is powered, generates lifting force opening brake B, realizes brake operation opening and elevator normal hoisting.
Two, float sliding concentrated setting
Service braking (from on-position is opened to): driver controller (can share an elevator driving controller, be not necessarily to Separately set dedicated drive control device, power source special) control elevator orderly shutdown (zero velocity), keep whole section of (containing A, B sections) mover logical Electricity lifts carriage, and mover (including subunit A, B), mover beam and back-shaped beam remain static, then, drive control device It is gradually reduced hovering and lifts electromagnetic force, when being less than the resultant force of self weight, reset spring and magnetic restoring force, composite plate A, B is resetting Edge on back-shaped beam is gradually moved to upwards under spring and magnetic restoring force collective effect, composite plate A, B and corresponding subunit A, B Between Normal Force be gradually increased, brake A, B closure, realize service braking.
Work is opened (from braking to opening state): drive control device (can share an elevator driving controller, without another If dedicated drive control device, power source special) whole section of (contain A, B section) mover of control be first powered to generating and lift mover beam, sedan-chair enough Then the lifting force of compartment frame and carriage drives mover beam, mover (including subunit A, B), back-shaped beam to move up with setting speed Bottom to composite plate A, B or the bottom close to composite plate A, B, the normal direction between composite plate A, B and corresponding subunit A, B Suction is gradually reduced, and brake A, B are opened, and realizes that brake operation is opened and elevator normal hoisting.
In the above-mentioned normal open or close course of work of two classes brake, it is shorter to mention or move down stroke on mover, generally exists Within tens millimeters (such as 20-60mm), the only impulse stroke quite with the electromagnet in ordinary electromagnetic formula deadman's brake.
In the case of accident power-off, mover is under self weight, reset spring and larger magnetic restoring force resultant force collective effect with several times Acceleration of gravity falls rapidly, primary Calculation, mover fall (i.e. brake) time be a few tens of milliseconds (such as 40ms) within, The distance of glide of carriage is less than 7mm, and gliding speed is less than 0.37m/s, if in view of when slipping down to about 1/2 left and right stroke, braking Device brake force has reached the maximum the 50% of brake force, from angle is rationally designed, by twice of dynamic braking safe clearance, at this time Carriage can be braked, distance of glide and speed are smaller, much smaller than safety tongs set action speed (when specified beyond carriage The 10% of the speed of service just acts, and the specified speed of service of the general above elevator of load-carrying 800kg is in 1 ~ 2.5m/s or more), it is sufficient to it protects Demonstrate,prove carriage and personnel safety.
Lifting force is not enough or in the case of running out of steam in lifting process: due to subunit A, B be simultaneously with other movers Unit undertakes together promotes load, and either subunit A, B or other any group of or multiple groups subunit occur Lifting force not enough or the situation that runs out of steam, as long as the load that the subunit of remaining work is born is without departing from the maximum being able to bear Lifting force (generally 1.5 ~ 2 times of specified lifting forces), continues to be controlled by system, once exceed maximum bearing ability, straight-line electric Machine step-out, no matter whether system sends out band-type brake instruction, and mover is made in self weight, reset spring (or tripping spring) and magnetic restoring force resultant force Under, the rapid automatic implementation lifting force of meeting lacks " self-protection " safety arrestment, fundamentally ensures elevator (elevator) Real time security and reliability, indiscriminate dynamic, the frequently dynamic, malfunction for avoiding the mandatory reserve protection of safety tongs cause clamp and system Dynamic rail generates destructiveness, severe impact, friction, vibration, the generation for the serious safeties accidents such as maintenance even personal injury of stopping transport.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
