Fig. 2 is the left view of specific embodiment of the utility model.
Fig. 3 is the structural drawing of calutron of the present utility model.
Embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Specific embodiment:
As shown in Figure 1 and Figure 2.Present embodiment by housing 1, be positioned at housing 1 inner chamber and form with moveable piston 2 and spring assembly that described inner chamber size is complementary.Housing 1 is a cylindrical housing, and the left side of housing 1 is provided with installs bulge loop 9, and it is one-body molded with housing 1 that bulge loop 9 is installed.Bulge loop 9 is installed is used for when tap changer is installed, being inserted in the mounting hole of retarder, make tap changer location, fixing.The sidewall of housing 1 is provided with overflow hole 14, moves in the inner chamber that piston 2 can housing, thus the opening or closing of the determining positions overflow hole 14 of piston 2 in housing 1, piston 2 is provided with vent 8.Spring assembly is made up of spring 3, mobilizable pressure adjusting spring seat 4, switch plate 5, adjustment bolt 6, catch bar 7.Switch plate 5 is fixed in the right-hand member of housing 1 also can be separable with housing 1.Spring 3 left ends stretch into the inner chamber of piston 2 and are pressing piston 2, and right-hand member places on the spring seat 4.Pressure adjusting spring seat 4 is provided with groove 16, and the left end that adjustment bolt 6 heads on pressure adjusting spring seat 4 places in the described groove 16, and right-hand member is threadedly connected on the switch plate 5.Adjusting bolt 6 is that basal plane produces relative displacement with switch plate 7, can adjust the position of spring seat 4 in housing 1.Adjust bolt 6 borings, catch bar 7 left ends pass adjustment bolt 6 and pass switch plate 5 simultaneously.Catch bar 7 right-hand member advancing meanss 15.
As shown in Figure 3.Advancing means 15 is a calutron, and calutron is made up of with the motion bar 13 that is being connected sucker 12 and is passing magnetic core 10 magnetic core 10, the coil 11 on last magnetic core 10, the sucker 12 that is positioned at magnetic core 10 left ends.Under the effect of electromagnetism, sucker 12 will be by on magnetic core 10, thereby makes motion bar 13 motions.Being connected of described motion bar 13 with catch bar 7.
Working principle:
During use, tap changer is installed in the inside of liquid eddy current rail brake, and switch plate is fixed on the liquid eddy current rail brake.Hydraulic oil enters in the inner chamber of housing from the left end of tap changer.According to requirements of one's work, can set the pressure of pressure regulation.When the pressure in when work surpassed the pressure of setting, hydraulic oil can back down piston outside overflow hole flows out housing, made the hydraulic fluid pressure of zone of high pressure of the continuous increase of liquid eddy current rail brake inside be no more than the pressure of setting, thereby reached the purpose of pressure regulation.When the stator of liquid eddy current rail brake inside was moved, must there be a pressure higher than setup pressure value the zone of high pressure of the hydraulic oil of liquid eddy current rail brake inside.Can start this moment, and advancing means makes push rod move to the left side.Push rod heads on the position that the pressure adjusting spring seat moves to setting left, thereby the pressure that makes spring impose on piston increases.Under such state, the hydraulic oil of the zone of high pressure of the hydraulic oil of liquid eddy current rail brake inside can obtain a more high pressure, thereby the stator that promotes the liquid eddy current rail brake moves to low pressure area, thereby makes the liquid eddy current rail brake enter the working state that produces braking axle.In the time will making the liquid eddy current rail brake withdraw from the working state that produces braking axle, the drive push rod of advancing means moves right, and makes the push rod returning position.Thereby spring imposes on the pressure of piston to be reduced, and the hydraulic fluid pressure of the zone of high pressure of liquid eddy current rail brake reduces.The stator of liquid eddy current rail brake is owing to the hydraulic fluid pressure minimizing of zone of high pressure is returned to the origin-location, and the liquid eddy current rail brake withdraws from the working state that produces braking axle.
Advancing means of the present utility model also can be used stepper motor etc., and other produces mechanism or the device that advances action.
