Embodiment
Describe in further detail below in conjunction with accompanying drawing the utility model.
Fig. 1 is the anti-error decomposition texture schematic diagram that disconnects an embodiment of pile of a kind of movable type of the utility model.Fig. 2 is the cutaway view of grounding base described in Fig. 1.As shown in Figures 1 and 2, this movable type ground stud comprises grounding base 1 and securing member 2.
Wherein, this grounding base 1 specifically comprises U type draw-in groove 11 and card post 12, and card post 12 is arranged on the outside of U type draw-in groove bottom surface, can be one-body molded between U type draw-in groove 11 and the card post 12, can certainly adopt welding, riveted joint or alternate manner to link together.On U type draw-in groove 11 one of them U type arm a penetrating screw 111 is set.Card post 12 is provided with ground wire hole 121, and jacket casing 123 has been sticked in this ground wire hole 121.This jacket casing 123 can be fixed in the ground wire hole 121 by hex nut 122.Hex nut 122 and/or jacket casing can use copper product to be processed into, to reduce contact resistance.Screw 111 can be vertical setting mutually with ground wire hole 121.
Wherein, securing member 2 specifically comprises top 21, rocking arm 23 and the threaded push rod 22 in middle part that adapts with described screw 111.One end of push rod 22 flexibly connects with top 21, and the other end is connected with rocking arm 23.The modes that push rod 22 and top 21 flexibly connect can make and come directly towards 21 bottoms and can get final product by direct-insert hole by be provided with one on push rod 22 and top 21 ends that are connected.Rocking arm 23 is divided on the rocking arm joint 231 and rocking arm joint 232 down, on the rocking arm end of joint 231 and rocking arm down joint 232 be rotationally connected, for example can adopt pivotally connected mode.Joint 231 the other end is connected with opposite end that push rod 22 flexibly connects top 21 and also can rotates around it on the rocking arm.Rocking arm joint 232 down is provided with a plurality of lockholes 2321.Can spaced set between described a plurality of lockhole 2321.
As Fig. 3, Fig. 4 and shown in Figure 5, joint 231 ends that are connected offer feather key 221 on push rod 22 and the rocking arm, and a pivot pin 222 is set in feather key 221, are arranged with spring 223 on the described pivot pin 222.Joint 231 ends that are connected with push rod 22 are provided with the keyway 2311 that adapts with feather key 221 on the rocking arm.
As shown in Figure 6, keyway 2311 outsides also are provided with a stop 2312, and these stop 2312 bottoms place described pivot pin 222 inside, are used to limit the sliding scale of feather key 221.
As described in Figure 7, the end face of described top 21 can be circle, and is stressed even to guarantee; And can also be milled with decorative pattern on the described end face, prevent to become flexible with the frictional force that increases described end face and earth electrode.
Wherein, an arc groove 112 also can be set on the U type arm of the U type draw-in groove 11 relative, can be used for fixing the column type earth electrode with screw 111.
During use, as shown in Figure 8, will come directly towards 21 and take off, and put between the two U type arms of grounding base 1 and alignd with screw 111 in the bottom of described top 21, and push rod 22 be screwed in the screws 111, and top 21 is inserted in the hole of push rods 22.At this moment, make to keep enough distances between top 21 and the arc groove 112, get final product even this distance is slightly larger than the thickness of earth electrode 4.Earth electrode 4 is connected on the U type arm and the grounding base 1 between the top 21 that is provided with arc groove 112, press down on the rocking arm of rocking arm 23 and save 231 this moment, the keyway 2311 of joint 231 matches on the feather key 221 that makes push rod 22 and the rocking arm, and inserts in the pivot pin 222 after stop 2312 being passed the top of keyway 2311.Grasping under the rocking arm joint 232 turns clockwise and makes it drive on rocking arm joint 231 around push rod 22 rotations, compress earth electrode 4 until top 21, then jacket casing 123 is inserted in earth connection termination 5, and earth connection termination 5 is fixed on the card post 12 by aerofoil profile nut 51, (this moment is because the effect of spring 223 for cycle rocking arm 23, feather key 221 is separated with keyway 2311, but can not make the push rod 22 loosening) make that the lockhole on the lockhole on the joint 232 2321 and earth connection termination 5 aligns rocking arm under, the lockhole and the rocking arm that mechanical coding lock 3 are inserted in earth connection termination 5 respectively descend in the lockhole 2321 of joint 232, at last mechanical coding lock 3 is pinned, then the whole operation process finishes.During use, because of mechanical coding lock 3 is provided with coding and has included anti-error management system in, this winding ground wire will can not torn open by leakage like this; In addition, because mechanical coding lock 3 makes to unscrew push rod 22, and has prevented that this winding ground wire from being torn open with rocking arm joint 232 pinnings down by mistake.
The described portable ground stud of present embodiment also is specially adapted to the maintenance to the isolating switch (isolation switch) that has mechanical coding lock.The annexation of this isolating switch is: earthed switch all is equipped with in its both sides, and is provided with mechanical coding lock between isolating switch and earthed switch.Be fixed in the ground wire hole 121 of this movable type ground stud by portable movable earth connection termination like this this isolating switch correspondence, mechanical coding lock on the operating grip of the earthed switch that it is corresponding (ground connection disconnecting link) takes off, and joint 232 under earth connection termination and the rocking bar is locked in the lump to get final product then.At this moment, the operation of combined floodgate earthed switch is become use this movable type ground stud to carry out the operation of hanging ground-wire in the residing position of this isolating switch exactly, this earth connection has been included the microcomputer anti-error management system in by mechanical coding lock equally like this.Thereby avoided existing in the prior art, when the earthed switch of isolating switch both sides enters "on" position, and isolating switch can not close a floodgate, and therefore can't overhaul the problem of debugging to this isolating switch; And if during with isolating switch both sides earthed switch separating brake, the job site of this isolating switch will lose the problem of ground protection again.
The above is a preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications on the basis of above-mentioned disclosed embodiment, these improvements and modifications also are considered as protection range of the present utility model.
