Abstract
The invention discloses an operating mechanism and a locomotive using the same. The magnets of the operating mechanism are permanent magnets; the permanent magnets are used for acting on a piston through an independent permanent magnetic force or a resultant force of the permanent magnetic force and air pressure in a switching-off cavity when switching on is performed in place, so that the piston can keep abutting against the switching-on end of a main cylinder. After the operating mechanism performs in-place switching on, the permanent magnets can act on the piston through the permanent magnetic force or the resultant force of the permanent magnetic force and air pressure in the switching-off cavity, so that an operating rod can be kept in a switching-on state under the driving of the piston. Compared with a structure in which an electromagnetic force provided by electromagnets is needed when an operating rod is kept in a switching-on state, the operating mechanism of the invention does not need the help of electromagnets when being in the switching-on state, and therefore, problems of instability of a switching-on retention force and high possibility of being burnout of electromagnetic coils which are brought about by continuous power supply of the electromagnetic coils of the electromagnets can be avoided, and the switching-on retention state of the operating mechanism can be stable.

Embodiment
The embodiment 1 of locomotive in the present invention: as shown in Figure 1, this locomotive comprises the operating mechanism of headstock and upper assembling thereof, operating mechanism belongs to high-voltage switch gear field, not only can be applicable to the vehicle-mounted switch control rule on locomotive, can also to be applied on automobile in other actuating systems.This operating mechanism comprises the Master cylinder body that cylindrical shell 104, upper end cover 103 and bottom end cover 109 are connected, Master cylinder body extends along divide-shut brake direction, and in cylindrical shell 104 along the vertical direction movement be equipped with piston 108, above-below direction is also the divide-shut brake direction of this operating mechanism setting, Master cylinder body inner cavity chamber is divided into the combined floodgate chamber being in top and the separating brake chamber being in below by piston 108, corresponding upper end cover 103 is in the combined floodgate end of cylindrical shell 104, and bottom end cover 109 is in the separating brake end of cylindrical shell 104.Bottom end cover 109 offers the separating brake side gas port 191 be communicated with between the external world and separating brake chamber, this separating brake side gas port 191 can control the charge and discharge of separating brake intracavity gas, the external port of separating brake side gas port 191 is on the outer peripheral face of bottom end cover 109, the inner port of separating brake side gas port 191 is on the upper surface of bottom end cover 109, namely the inner port of separating brake side gas port 191 is arranged towards the lower surface of piston 108, and in the external port of separating brake side gas port 191, be connected with the electromagnetically operated valve controlling its break-make.Bottom end cover 109 and upper surface are all sealed and matched with cylindrical shell 104, to ensure inner cavity chamber's sealing of Master cylinder body.The upper end of piston 108 is coaxially connected output shaft 102, the guiding perforation middle punch that the upper end of output shaft 102 is offered from upper end cover 103 center, the wall surface of the hole of this guiding perforation and the outer peripheral face of output shaft 102 lead cooperation along the vertical direction, output shaft 102 both directly as the actuating bar of whole operating mechanism, also can be able to be connected on the actuating bar of operating mechanism from the part passed that leads.On the periphery of output shaft 102, be equipped with can with the dynamic iron core 107 of divide-shut brake direction movement of output shaft 102 along setting for fixed cover, this dynamic iron core 107 is between upper end cover 103 and piston 108, and the combined floodgate that dynamic iron core 107 and output shaft 102 define in the upper end of piston 108 towards projection is protruding.The internal face of cylindrical shell 104 is also fixed with the magnetosheath 106 be between upper end cover 103 and piston 108, the periphery of this magnetosheath 106 is installed with permanent magnet, internal face to lead with dynamic iron core 107 along the vertical direction and coordinate, permanent magnet and magnetosheath 106 all and upper end cover 103 interval arrange.The part of stretching out from upper end cover 103 of output shaft 102 upper end is connected with the tripping spring 101 be in outside Master cylinder body, and tripping spring 101 is the stage clip of downward pushing tow output shaft 102, dynamic iron core 107 and piston 108.Wherein upper end cover 103, magnetosheath 106, cylindrical shell 104, dynamic iron core 107 are all the magnetic conductive parts be made up of soft magnetic material, and bottom end cover 109 can adopt soft magnetic material, also can adopt 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 the confining force of gate-dividing state primarily of the composition of making a concerted effort of the elastic force of tripping spring 101 or the permanent magnetic attraction of permanent magnet or permanent magnetic attraction and elastic force, namely when bottom end cover 109 adopts soft magnetic material, along with piston 108 drives dynamic iron core 107 and output shaft 102 separating brake to put in place, piston 108 can be connected with bottom end cover 109 magnetic conduction, now the magnetic field of permanent magnet 105 can be moved iron core 107-magnetosheath 106-permanent magnet 105 by cylindrical shell 104-bottom end cover 109-piston 108-successively and form closed separating brake magnetic loop, so just can by the independent confining force providing gate-dividing state of the permanent magnetic attraction of permanent magnet 105, can certainly with tripping spring 101 acting in conjunction and by the confining force of making a concerted effort to provide of permanent magnetic attraction and elastic force, operating mechanism is made to keep open position, when bottom end cover 109 adopts non-magnet material, even if when piston 108 contacts bottom end cover 109, bottom end cover 109 also can block above-mentioned closed magnetic loop, so the elastic force of tripping spring 101 can only be relied on to provide confining force, makes Cao east structure keep open position.
In making process, after operating mechanism is subject to switching signal, electromagnetically operated valve is opened, and gas enters in the separating brake chamber of Master cylinder body from separating brake side gas port 191, and gas pressure, on the bottom surface of piston 108, applies pressure power upwards on piston 108.Until when the atmospheric pressure that piston 108 is subject to is greater than (bottom end cover 109 adopts soft magnetic material) with joint efforts of the elastic force (bottom end cover 109 adopts non-magnet material) of spring or the permanent magnetic attraction (bottom end cover 109 adopts soft magnetic material) of permanent magnet or permanent magnetic attraction and elastic force, piston 108 starts to move up, and depart from bottom end cover 109 at piston 108, and and after forming certain air gap between bottom end cover 109, even if bottom end cover 109 adopts soft magnetic material, but because the magnetic resistance of air is larger, so the permanent magnetic attraction between piston 108 and bottom end cover 109 can reduce rapidly along with the increase of air gap, now piston 108 on move the elastic force that only need overcome tripping spring 101, the acceleration that piston 108 is moved up increases sharply, to accelerate the closing speed of operating mechanism.Until when the upper surface of iron core contacts with the bottom surface of upper end cover 103, making process terminates.
When operating mechanism is in combined floodgate hold mode, when dynamic iron core 107 contacts with upper end cover 103, the magnetic field that permanent magnet 105 produces can be moved iron core 107-magnetosheath 106-permanent magnet 105 by permanent magnet 105-cylindrical shell 104-upper end cover 103-successively and form closed combined floodgate magnetic loop, now iron core can remain on closing position under the force action of the atmospheric pressure of the permanent magnetic attraction of permanent magnet 105 and separating brake intracavity gas, namely the permanent magnetic attraction of permanent magnet 105 is the elastic force being less than tripping spring 101, by this part difference of atmospheric pressure compensating of separating brake intracavity gas, and make the elastic force making a concerted effort to be greater than tripping spring 101 of permanent magnetic attraction and atmospheric pressure, like this with compensated the situation of this part difference in documents by electromagnet compared with, can avoid the solenoid of electromagnet continue be energized caused by solenoid easy burn-out, combined floodgate hold mode is unstable, with the words compared with current pressure-operated operation mechanism, without the need to electromagnetically operated valve conducting always, the coil avoiding electromagnetically operated valve continues the problem be with the heating caused by point and even burnt out, simultaneously because the requirement of operating mechanism in the present embodiment to atmospheric pressure is lower, so the occasion of origin pressure transient can be applicable to.
The mode of no-voltage trip is adopted in operating mechanism separating brake process, because mainly rely on during combined floodgate hold mode permanent magnetic attraction and atmospheric pressure make a concerted effort confining force is provided, so after operating mechanism receives sub-gate signal, electromagnetically operated valve action, separating brake intracavity gas can be discharged from separating brake side gas port 191, such piston 108 is under the effect losing atmospheric pressure, permanent magnetic attraction is not enough to the elastic force overcoming tripping spring 101, such piston 108 can move down under the elastic force effect of tripping spring 101, operating mechanism is made to start separating brake, and provide separating brake power by tripping spring 101 in the process.
