Description
Technical field
The utility model relates to relay construction technical field, the high antivibration relay electro-magnetic system of the one especially for gravity type railway signal relay.
Background technology
At present, traditional railway signal relay is gravity type, as shown in Figure 3, its electromagnetic system comprises yoke 1, coil 2, iron core 3 and angle-style armature 4, armature is articulated in yoke end, is not departed from by steel wire card 17 holding armature, and the gigback of armature is gravity-type structure, its structure is add heavy punch piece 18 at the movable part of armature, ensures that the armature of relay returns by gravity.The armature of relay of this structure is in free state, normally-closed contact is in closure state, heavy punch piece adds the moment of inertia of armature moving part simultaneously, when relay is subject to the environmental mechanics such as vibration, the impact acceleration interference of vertical direction, armature clashes into iron core pole-face with larger impulsive force, the motion of armature causes pull bar servo-actuated, and under pull bar drives, normally-closed contact separates mistakenly.The vibration index that China railways standard GB/T7417-2010 specifies requires: relay can bear the frequency that shakes for 15Hz, amplitude is the vibration of 0.45mm, the EN50578 standard-required that International Union of Railways formulates: shake frequently between 5-22Hz, peak swing is 1mm, and shake frequently between 22-50Hz, acceleration is 2g, and relay must possess normal function.It is poor that armature due to electromagnetic system returns machine vibration resistance, causes the overall anti-vibration performance of relay poor, can only meet China railways standard, but not reach the standard of International Union of Railways.
Summary of the invention
The purpose of this utility model is to provide a kind of high antivibration relay electro-magnetic system, the resistance to shock solving the electromagnetic system of Conventional gravity formula railway signal relay is poor, being subject under the interference such as larger vibration or large impact power, easily there is the technical problem of by mistake hitting iron core in armature.It can effectively reliably under the interference of larger vibration and impact acceleration use.
The technical scheme that the utility model adopts is: this high antivibration relay electro-magnetic system comprises yoke, coil, iron core and angle-style armature, armature is articulated in yoke end, its technical essential is: armature is provided with spring gigback, spring gigback is: on yoke, be fixed with the screw rod with Self locking nuts, screw sleeve is equipped with outer spring, outer spring passes through spring fixed cap apical grafting in Self locking nuts lower surface, armature epimere is provided with the circular groove of central through hole, described screw rod runs through the central through hole of armature, outer spring lower end is crimped in the groove of described armature.
Further, be also set with inner spring in the cavity between described screw rod and outer spring, spring fixed cap described in the apical grafting of inner spring upper end, inner spring lower end is crimped on the lining of screw head through described central through hole.
Described yoke front portion is straight plate shape, and yoke front end is provided with fixed head, and the bent angle bottom of armature is articulated in the notch of fixed head, and notch is connected with geometrical clamp.
The good effect that the utility model has is: because the utility model adopts spring gigback, by the outer spring of spring formula gigback, confining force is applied to armature, control armature returning in free state, the screw rod with Self locking nuts is adopted to pass armature, suit outer spring, reached cleverly by above structure and regulate outer spring and support and control is carried out to armature, the confining force of outer spring and armature self gravitation is utilized to resist outside larger vibration and weaken impulsive force, greatly reduce the situation that armature clashes into iron core by mistake, therefore, spring is returned system and is also served fixation to armature, prevent vibration before and after armature, add the confining force of armature in off-position simultaneously, improve resistance to shock, geometrical clamp directly over armature is also for fixed armature, prevents the upper and lower vibration of armature, improves the reliability of electromagnetic system, improve the vibration resistance of relay simultaneously, and its structure is simple, meets or exceeds the EN50578 standard that International Union of Railways formulates.

Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is perspective view of the present utility model;
Fig. 2 is decomposing state structural representation of the present utility model;
Fig. 3 is existing electromagnetic system structure schematic diagram.
In figure sequence number illustrate: 1 yoke, 2 coils, 3 iron cores, 4 armature, 5 geometrical clamps, 6 armature bent angles, 7 outer springs, 8 inner springs, 9 spring fixed caps, 10 screw rods, 11 Self locking nuts, 12 armature epimeres, 13 grooves, 14 central through holes, 15 fixed heads, 16 linings, 17, steel wire card, 18 heavy punch pieces.
Embodiment
In order to make the utility model easy to understand, concrete structure of the present utility model is described in detail according to Fig. 1 ~ 2, as shown in Figure 1, a kind of high antivibration relay electro-magnetic system, for railway signal relay for embodiment, this electromagnetic system comprises yoke 1, coil 2, iron core 3, angle-style armature 4 and spring gigback, armature is articulated in yoke end, and armature epimere 12 is horizontally set, makes return movement for being connected with gigback, armature hypomere is longitudinally arranged, for adsorbing with iron core.The spring gigback of armature adopts: on yoke, be fixed with the screw rod 10 with Self locking nuts 11, screw rod adopts square toes screw rod, screw sleeve is equipped with outer spring 7, outer spring passes through spring fixed cap 9 apical grafting in Self locking nuts 11 lower surface, the circular groove 13 of central through hole 14 is provided with at armature epimere 12, screw rod 10 runs through the central through hole 14 of armature, and central through hole diameter is greater than outer screw diameter, and outer spring 7 lower end is crimped in the groove 13 of described armature.Outer spring is by the resilient support armature of self, and holding armature position, can by the pressure regulating Self locking nuts 11 to adjust spring.
As further improvement, be also set with inner spring 8 in the cavity between screw rod and outer spring, inner spring upper end apical grafting spring fixed cap 9, inner spring lower end is crimped on the lining 16 of screw head through described central through hole 14.The fixed head 15 of yoke 1 end is also provided with hole slot, and the head of screw rod is stuck in hole slot by lining, convenient for assembly fixing.
