Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in Fig. 1 combinations Fig. 2,3, a kind of earthing switch back door interlocking device, including the peace on switch cabinet body 7
The first locking part 2 shelved 1 and be connected with grounding switch main shaft 8, the mounting bracket 1 are equipped with the second locking part 3, institute
The first locking part 2 stated is equipped with the first interlocking portion 21 and the second interlocking portion 22, and second locking part 3 has to be opened in ground connection
The second state stretched out after being opened when closing separating brake by the first state of 21 locking of the first interlocking portion on the first locking part 2 and cabinet door 9,
There is first locking part 2 the second interlocking portion 22 when the second locking part 3 is in first state to be connected with door of switch cabinet 9
The second place opened when the first position of lock and earthing switch close a floodgate with the unlock of door of switch cabinet 9 easy to door of switch cabinet 9, institute
First interlocking portion 21 matches somebody with somebody with 3 rotary spacing of the second locking part on the first locking part 2 when the first locking part 2 stated is in the second place
Close.The utility model is provided with the first locking part and the second locking part, due to the linkage of the first locking part and main shaft, when realization pair
First locking part is avoided that main shaft malfunctions when interlocking so that main shaft interlocking is reliable, so as to avoid opening in rear door of switch cabinet
When main shaft malfunction, there is provided the second locking part, when door of switch cabinet closes grounding switch tripping, the second locking part is by first
First interlocking portion axial limiting of locking part, the first interlocking portion and the switch cabinet gate interlock of the first locking part, avoids main shaft from turning
Door of switch cabinet malfunction is opened during dynamic, when cabinet door is opened, the second locking part stretching mounting bracket to the first locking part into
Row rotary spacing, so as to avoid main shaft from malfunctioning.The utility model also have it is simple in structure, easy to assembly, parts are few, production
The advantages that cost is low, and interlocking is reliable, stable action, and response is fast, and service life is long.Interlock is set on grounding switch main shaft,
When earthing switch, which is in "on" position, closes cabinet door (sealing plate or back door), the pushing part of the barb pushing tow STATEMENT OF FEDERALLY SPONSORED in cabinet door makes
Obtain STATEMENT OF FEDERALLY SPONSORED to slide with respect to mounting bracket, STATEMENT OF FEDERALLY SPONSORED drives the second locking part with respect to mounting bracket sliding and STATEMENT OF FEDERALLY SPONSORED to lead to by connector
Connector compression return unit is crossed, the second locking part is retracted in mounting bracket at this time, releases the interlocking to main shaft, main shaft can be free
Rotate, carry out operational grounding separating brake switching manipulation, when switchgear separating brake, the second interlocking portion rotates and the barb in cabinet door at this time
The dead door of switch cabinet of phase clamping lock；At this time, the first interlocking portion of the first locking part is just arranged on going out on the second locking part mounting bracket
Mouthful position, blocks the second locking part, avoids the second locking part from axially being resetted along it, at this time the second interlocking portion of the first locking part with
The barb of cabinet door is mutually locked, i.e. grounding switch tripping state, and cabinet door cannot be opened；When main axis so that earthing switch is in combined floodgate
During state, the first interlocking portion unlocks the second locking part after the first locking part rotates, and the second interlocking portion is with respect to door of switch cabinet solution
Lock, back door (sealing plate) unlock can open, the second locking part ejects under the drive of STATEMENT OF FEDERALLY SPONSORED and return unit, back door open after this
When due to the change in location of the second locking part, the first interlocking portion of the first locking part and the outer surface rotary spacing of the second locking part
Coordinate, the first locking part cannot be rotated by locked at this time, prevent ground connection main shaft from rotating, i.e., main shaft cannot carry out after back door is opened
Sub-switching operation, earthing switch can not separating brake, avoid error operation of grounding switch ensure service personnel safety.
The second interlocking portion 22 is arranged on the end of the first locking part 2 and when the first locking part 2 is in first position
Interlocked with 9 phase of cabinet door.Such structure rational in infrastructure using the first locking part so that the first locking part and cabinet door interlocking are convenient
Reliably.
The first interlocking portion 21 and the second interlocking portion 22 are in sector.Specifically, the second interlocking portion 22
Surface area be more than the first interlocking portion 21 surface area.Fan-shaped structure causes the first interlocking portion and the second interlocking portion in reality
During interlocking, interlocking is reliable, spacing reliable especially by interlocking is rotated.Due to the difference of area so that connect in main shaft
When ground switch "on" position turns to gate-dividing state, door of switch cabinet is main when gate-dividing state turns to "on" position first with being locked
After axis in-place closing, cabinet door could be opened, and the interlock time of cabinet door relatively more long, ensures the safety of operating personnel.
Second locking part 3, which is arranged on mounting bracket 1 and is slid with mounting bracket 1, to be coordinated.Specifically, described second
Locking part 3 is equipped with STATEMENT OF FEDERALLY SPONSORED 4, and the STATEMENT OF FEDERALLY SPONSORED 4 is connected with the second locking part 3.The setting of STATEMENT OF FEDERALLY SPONSORED causes second
Main only its interlock of locking part, simple in structure, interlocking is reliable.
One end of the STATEMENT OF FEDERALLY SPONSORED 4 is equipped with the pushing easy to 9 barb of cabinet door, 91 pushing tow through mounting bracket 1 and on the end
Portion 41.Specifically, the mounting bracket 1 is equipped with supporting item 5, and 4 and second locking part 3 of STATEMENT OF FEDERALLY SPONSORED is each passed through branch
Support member 5, mounting bracket 1, are connected by connector 6 between 4 and second locking part 3 of STATEMENT OF FEDERALLY SPONSORED.By STATEMENT OF FEDERALLY SPONSORED and
The setting of connector causes the second locking part stable action, and steering capability is good, and interlocking is reliable.The setting of supporting item so that distich
Moving part and the second locking part play the role of support and guiding, so that locking part stability of rotation.It is more specifically, described
Return unit 42 is arranged with STATEMENT OF FEDERALLY SPONSORED 4, one end and the supporting item 5 of the return unit 42 offset, and the other end offsets with connector 6,
The return unit 42 has movement tendency of the driving STATEMENT OF FEDERALLY SPONSORED 4 close to cabinet door 9.The setting of return unit can make in "on" position
The second locking part and STATEMENT OF FEDERALLY SPONSORED reliably eject so that locking part reliable in action facilitate it is steady.
First locking part 2 is equipped with the mounting groove 23 of strip, is equipped with the mounting groove 23 and is used to fix
The installation bolt 24 of first locking part 2.It is axial micro- that the setting of strip mounting groove allows the position of the first locking part to carry out
Adjust so that product is easy for installation, and interlocking is reliable.
Every technical staff's notice：Although the utility model is described according to above-mentioned embodiment, this
The invention thought of utility model is not limited to that utility model, and any repacking with inventive concept, will all include this specially
