Description
Technical field
The present invention relates to a kind of operating mechanism and use the locomotive of the operating mechanism.
Background technique
Currently, being mostly spring operating mechanism and permanent magnet operating machine in the operating mechanism that high-voltage switch gear and related fields use
Structure, but structure is complicated for spring operating mechanism, and incipient fault point is more, and mechanical life is low, is extremely difficult to the requirement of long-life；Permanent magnetism behaviour
It is simple to make mechanism structure, mechanical life is long, but permanent-magnet manipulating mechanism needs the power supply of large capacity, splitting or integrating lock pair in movement
Power supply system causes certain impact, influences other equipment normal work, therefore spring operating mechanism and permanent-magnet manipulating mechanism exist
Certain limitation is all had in use process.In locomotive vehicle-mounted equipment and other special occasions, it is desirable that the operating mechanism service life
Long, power supply capacity is smaller, therefore pneumatic operator is optimal selection, pneumatic mechanism is long with mechanical life, structure is simple,
Convenient for installation and maintenance, the advantages that gas is resourceful, pollution-free, but pneumatic operator also have simultaneously load characteristic it is poor,
Closing speed is not easy to improve, electromagnetic valve coil charges disadvantage easy to damage of easily generating heat for a long time, therefore traditional pneumatic operating mechanism
The requirement that heavy load is run in locomotive vehicle-mounted equipment and other special occasions can not be met.

A upper ring end face is bonded with the lower ring end face of inside and outside iron core, to be constituted closed magnetic by magnet, outer iron core, piston and interior iron core
Circuit, the magnetic field that electromagnet and permanent magnet generate in magnet are overlapped mutually, and magnetic field resultant force is only slightly more than point of tripping spring
Lock power, to realize that separating brake is kept；In separating brake, electromagnet power loss, the magnetic force of permanent magnet is less than the elastic force of tripping spring, separating brake
Spring can push actuating bar to move down together with piston, make the inner and outer ends face of piston and the lower end surface point of inside and outside iron core
Power disconnects former closed magnetic circuit, and magnetic resistance increases, and the decaying of the attraction of permanent magnet also quickly, such tripping spring can push
Actuating bar quickly moves down together with piston and completes separating brake movement.But under combined floodgate hold mode, electromagnet in the operating mechanism
Electromagnetic coil need to continue to charge, to guarantee to have between magnet and piston enough electromagnetic attractions, and because electromagnetic coil is in outer
In iron core, outer iron core can hinder the heat dissipation of electromagnetic coil, so the calorific value of the electromagnetic coil persistently charged can be larger, so not
But the magnetism of electromagnet can be made unstable, and in the case where electromagnetic coil persistent fever cannot radiate in time again, electromagnetism
The service life of coil can shorten, or even be burned, therefore combined floodgate shape is kept using electromagnet and permanent magnet collective effect
The operating mechanism of state is easy to appear the unstable problem of closing retention force in use, causes the reliability and stabilization closed a floodgate

Specific embodiment
The embodiment 1 of locomotive in the present invention: as shown in Figure 1, the locomotive includes headstock and the operating mechanism assembled thereon, behaviour
Motivation structure belongs to high-voltage switch gear field, may be applied not only to the vehicle-mounted switch control on locomotive, can be applied on automobile it
In his actuating system.The operating mechanism includes Master cylinder body made of cylinder 104, upper end cover 103 and lower cover 109 are connected, master cylinder
Body extends along divide-shut brake direction, and movement is equipped with piston 108 along the vertical direction in cylinder 104, and up and down direction is also the behaviour
Master cylinder chamber inside body is divided into the combined floodgate chamber in top and is below by the divide-shut brake direction of dynamic mechanism sets, piston 108
Separating brake chamber, corresponding upper end cover 103 is in the combined floodgate end of cylinder 104, and lower cover 109 is in the separating brake end of cylinder 104.Under
Separating brake side port 191 of the connection between extraneous and separating brake chamber is offered on end cap 109, the separating brake side port 191 is controllable to be divided
The external port of the charge and discharge of lock intracavity gas, separating brake side port 191 is on the outer peripheral surface of lower cover 109, separating brake side port 191
Inner port is on the upper surface of lower cover 109, that is, separating brake side port 191 inner port towards the lower end surface of piston 108
Arrangement, and the solenoid valve for controlling its on-off is connected in the external port of separating brake side port 191.Lower cover 109 and upper surface are equal
It seals and cooperates with cylinder 104, to guarantee inner cavity chamber's sealing of Master cylinder body.The upper end of piston 108 coaxially be connected output shaft 102, it is defeated
The guiding perforation middle punch that the upper end of shaft 102 is opened up from 103 center of upper end cover, the wall surface of the hole and output shaft of guiding perforation
102 outer peripheral surface is oriented to cooperation along the vertical direction, and output shaft 102 both can be directly as whole from the part that guiding is pierced by
The actuating bar of a operating mechanism, can also be connected on the actuating bar of operating mechanism.Fixing sleeve is equipped on the periphery of output shaft 102
The dynamic iron core 107 that can be moved with output shaft 102 along the divide-shut brake direction of setting, the dynamic iron core 107 are in upper end cover 103 and piston
Between 108, dynamic iron core 107 and output shaft 102 form combined floodgate protrusion raised upward in the upper end of piston 108.Cylinder 104
The magnetosheath 106 being further fixed between upper end cover 103 and piston 108 on inner wall is installed with forever on the periphery of the magnetosheath 106
Magnet, inner wall are oriented to dynamic iron core 107 along the vertical direction to be cooperated, and permanent magnet and magnetosheath 106 are spaced cloth with upper end cover 103
It sets.The tripping spring 101 outside Master cylinder body, separating brake are connected on the part that the slave upper end cover 103 of 102 upper end of output shaft stretches out
Spring 101 is the pressure spring of downward pushing tow output shaft 102, dynamic iron core 107 and piston 108.Wherein upper end cover 103, magnetosheath 106, cylinder
Body 104, dynamic iron core 107 are all the magnetic conductive parts made of soft magnetic materials, and lower cover 109 can use soft magnetic materials or adopt
Use non-magnet material.
When operating mechanism is in separating brake hold mode, piston 108 drives dynamic iron core 107 and output shaft 102 to keep separating brake
The retentivity of state is mainly by the resultant force group of the elastic force of tripping spring 101 or the permanent magnetic attraction of permanent magnet or permanent magnetic attraction and elastic force
At living as piston 108 drives dynamic iron core 107 and 102 separating brake of output shaft in place that is, when lower cover 109 is using soft magnetic materials
Plug 108 can be connect with 109 magnetic conduction of lower cover, and it is living to pass sequentially through cylinder 104- lower cover 109- for the magnetic field of permanent magnet 105 at this time
It fills in 108- dynamic iron core 107- magnetosheath 106- permanent magnet 105 and forms the separating brake magnetic loop being closed, it thus can be by permanent magnet 105
Permanent magnetic attraction the retentivity of gate-dividing state is individually provided, naturally it is also possible to 101 collective effect of tripping spring by permanent magnetism
The resultant force of suction and elastic force provides retentivity, so that operating mechanism keeps open position；When lower cover 109 uses non-magnet material
When, even if lower cover 109 can also block above-mentioned closed magnetic loop in the case where piston 108 contacts lower cover 109, so only
Retentivity can be provided by the elastic force of tripping spring 101, so that Cao east structure keeps open position.
In making process, after operating mechanism is by switching signal, solenoid valve is opened, and gas is from separating brake side port 191
Separating brake into Master cylinder body is intracavitary, and gas pressure applies upward pressure power on piston 108 on the bottom surface of piston 108.Directly
The atmospheric pressure being subject to piston 108 is greater than the elastic force (lower cover 109 uses non-magnet material) of spring or the permanent magnetism of permanent magnet
It is living when resultant force (lower cover 109 uses soft magnetic materials) of suction (lower cover 109 uses soft magnetic materials) or permanent magnetic attraction and elastic force
Plug 108 is begun to move up, and after piston 108 is detached from lower cover 109 and forms certain air gap between lower cover 109, i.e.,
Make lower cover 109 using soft magnetic materials, but since the magnetic resistance of air is larger, so the permanent magnetism between piston 108 and lower cover 109
Suction can be reduced rapidly with the increase of air gap, and moving up for piston 108 need to only overcome the elastic force of tripping spring 101 at this time, be made
It obtains the acceleration that piston 108 moves up to increase sharply, to accelerate the closing speed of operating mechanism.Until iron core upper surface and
When the bottom surface contact of upper end cover 103, making process terminates.
When operating mechanism is in combined floodgate hold mode, in the case where dynamic iron core 107 and upper end cover 103 contact, permanent magnetism
The magnetic field that body 105 generates can pass sequentially through permanent magnet 105- cylinder 104- upper end cover 103- dynamic iron core 107- magnetosheath 106- permanent magnet
105 and formed closure combined floodgate magnetic loop, iron core can be in the air pressure of the permanent magnetic attraction and separating brake intracavity gas of permanent magnet 105 at this time
Closing position is maintained under the force action of pressure, i.e. the permanent magnetic attraction of permanent magnet 105 is less than the elastic force of tripping spring 101
, by this partial difference of the atmospheric pressure compensating of separating brake intracavity gas, and the resultant force of permanent magnetic attraction and atmospheric pressure is greater than and is divided
The elastic force of lock spring 101 can avoid in this way compared with the case where compensating this partial difference by electromagnet in documents
The electromagnetic coil of electromagnet is persistently powered caused electromagnetic coil easy burn-out, and combined floodgate hold mode is unstable；With current gas
Constantly on without solenoid valve if dynamic formula operating mechanism is compared, the coil for avoiding solenoid valve continues the hair caused with point
Heat or even the problem of burn out, at the same because in the present embodiment requirement of the operating mechanism to atmospheric pressure it is lower, so can be suitable for
The occasion of origin pressure transient.
During operating mechanism separating brake by the way of no-voltage trip, because relying primarily on permanent magnetism suction when combined floodgate hold mode
Power and the resultant force of atmospheric pressure provide retentivity, so after operating mechanism is connected to sub-gate signal, electromagnetism valve events, separating brake is intracavitary
Gas can be discharged from separating brake side port 191, and under the action of losing atmospheric pressure, permanent magnetic attraction is not enough to such piston 108
Overcome the elastic force of tripping spring 101, such piston 108 can move down under the elastic force effect of tripping spring 101, so that actuating
Mechanism starts separating brake, and provides separating brake power by tripping spring 101 in the process.
The embodiment 2 of locomotive in the present invention: as shown in Fig. 2, the present embodiment difference from example 1 is that, actuating
Combined floodgate side port 231 is offered in mechanism on upper end cover 203, the external port of the combined floodgate side port 231 is in the outer of upper end cover 203
On circumferential surface, inner port face in the top of iron core, and the outer end of the external port for the side port 231 that closes a floodgate and separating brake side port 291
Mouth not only can be by the relatively independent control of two solenoid valves, but also can be managed collectively by same solenoid valve.In this way in operating mechanism
In making process, combined floodgate intracavity gas can be discharged from combined floodgate side port 231.During the opening process, actuating in the present embodiment
The separating brake mode of mechanism uses tripping spring 201 and the coefficient mode of Pneumatic pressure, i.e. operating mechanism is being connected to separating brake letter
After number, if separating brake side port 291 and combined floodgate side port 231 are using same solenoid valve control, solenoid valve commutation, gas is from conjunction
Lock side port 231 is filled with combined floodgate chamber so that piston 208 upper end be pressurized and be pressed downward division lock chamber, separating brake intracavity gas from point
It is discharged in lock side port 291, until the resultant force of the intracavitary atmospheric pressure of combined floodgate and tripping spring 201 is greater than the intracavitary atmospheric pressure of separating brake
When with the resultant force of the permanent magnetic attraction of permanent magnet 205, piston 208 starts to move down, and operating mechanism starts separating brake, and is entirely dividing
Separating brake power is provided by combined floodgate intracavity gas pressure and the resultant force of the elastic force of tripping spring 201 during lock.

It is in off-position under state, is only opened under "on" position, but under combined floodgate hold mode, closing retention force both can be with
Be permanent magnet 305 permanent magnetic attraction and separating brake intracavity gas atmospheric pressure resultant force, can also be inhaled by the permanent magnetism of permanent magnet 305
Power is provided separately, and when closing retention force belongs to latter instance, permanent magnetic attraction has been greater than tripping spring 301 in combined floodgate hold mode
Under elastic force.During the opening process, operating mechanism relies on 301 collective effect of separating brake magnet 300 and tripping spring in the present embodiment
Mode, i.e., after operating mechanism is connected to sub-gate signal, separating brake magnet 300 be powered, separating brake magnet 300 generate magnetic field be with forever
The opposing magnetic field that the positive magnetic field that magnet 305 generates is cancelled out each other, this magnetic field for allowing for the generation of separating brake magnet 300 can be offset forever
The magnetic field that magnet 305 generates, so that the permanent magnetic attraction that dynamic iron core 307 is subject to is reduced rapidly, until the permanent magnetic attraction of permanent magnet 305
When being less than the elastic force of tripping spring 301 with the resultant force of the atmospheric pressure of separating brake intracavity gas or individual permanent magnetic attraction, piston 308
It is moved down under the action of elastic force, operating mechanism starts separating brake, and provides separating brake by tripping spring 301 during separating brake and move
