Description
Technical field
The present invention relates to a kind of interlock of switchgear, specifically valve locking device in armoured.
Background technology
Valve in existing armoured is along with the propelling of circuit breaker trolley or other function dolly and exits, the upper lower plate gear shaft that promotes valve mechanism promotes moving up and down of valve, thereby the connector of a joint sleeve of realization shielding.Existing mechanism does not have interlock, can only merely realize dolly and advance valve to open, and dolly exits valve and cuts out.Not locking of valve when dolly exits, upper and lower push-and-pull valve artificially, thus open the sleeve pipe connector of a bus, in the situation that bus bar side is charged, very easily cause electric shock accidents.
Summary of the invention
The object of the invention is to overcome the deficiency in above-mentioned background technology, valve locking device in a kind of armoured is provided, this locking device can be realized automatically locking of valve, and have simple in structure, feature simple, easy to use is installed.
The technical solution used in the present invention is:
Valve locking device in armoured, it is characterized in that: described locking device is between valve mechanism and equipment inner wall, comprise this body support frame of door font being fixed on described equipment inner wall, the opening of this this body support frame is arranged towards dolly entrance, on the crossbeam of this body support frame, be shaped with the fixed head stretching along crossbeam length direction, on this fixed head, by two slide bars, one portable plate is installed, on slide bar between portable plate and fixed head, cover has spring, portable plate is provided with two lock pins towards the one side of valve mechanism, on the upper plate of valve mechanism and lower plate, offer respectively a lockhole, on pedestal, also offer a lockhole corresponding with the lockhole of upper plate, two lock pins insert respectively the lockhole of lower plate, in the lockhole of upper plate and pedestal, on two parallel support arms of this body support frame, be respectively equipped with a slide block, the chute of each slide block stretches along the length direction of support arm, after having two backstays to pass through chute, be positioned on support arm, separately there is one end of a spring to be fixed on slide block, the other end is fixed therein on a positioning rod, one end of slide block is shaped with for promoting the angle of described portable plate, and the other end is shaped with the baffle plate towards equipment entrance.
Described portable plate is parallel with fixed head, and lock pin is parallel with slide bar and perpendicular to portable plate, fixed head and chute.
Operation principle of the present invention is:
At dolly, push in cupboard process, first dolly push pedal 11 contacts with the slide block 7 of this locking device, the slide block pushing tow portable plate 5 of thrust unit makes it along slide bar 3, move, lock pin from the lockhole 20 of lower plate and the lockhole of winning in succession, deviate from (lock pin of winning in succession insert simultaneously win in succession and the lockhole of pedestal 14 in), remove the lock-out state of valve mechanism, then dolly push pedal just contacts with upper plate gear shaft 12, lower plate gear shaft 13, promotes upper plate 15, lower plate 16 and then promotes upper valve 18, lower valve 17.When dolly exits, dolly push pedal first with valve mechanism on, lower plate gear shaft is separated, the upper lower plate of valve mechanism resets under the effect of spring 2, on, lower valve resets, block sleeve opening, isolation live part, then dolly push pedal is separated with the slide block of locking device, portable plate resets by the effect of spring, two lock pins reenter the lockhole of lower plate, in the lockhole of upper plate and pedestal, again by the upper lower plate of valve mechanism and the locking of connecting plate pedestal, removing so artificially to promote upper and lower valve cannot promote, only have locking device compulsive unlocking, just can so that on, lower valve does not slide up and down in the situation that having dolly to push.
The invention has the beneficial effects as follows: in armoured, valve locking device is for automatically locking at the indoor valve of armoured circuit breaker, to avoid after circuit breaker trolley or the extraction of other function dolly, maintenance or cleaning worker are opened valve without authorization and get an electric shock; Feature is: 1. simple in structure, without the transformation original structure of switch cubicle and structure; 2. install simply, only need on original valve mechanism, stamp two holes and just can install, practical function; 3. the lock function of valve can automatically terminate along with the propelling of circuit breaker trolley or other function dolly, along with circuit breaker trolley or exiting of other function dolly and automatically lock; 4. can realize compulsive unlocking function.

Embodiment
Below in conjunction with Figure of description, the invention will be further described, but the present invention is not limited to following examples.
As shown in Figure 1, valve locking device in armoured, is arranged between valve mechanism and equipment inner wall, and two valve mechanisms respectively configure a locking device.
Each locking device comprises this body support frame of door font 6 being fixed on described equipment inner wall, the opening of this this body support frame is arranged (two parallel leg that are this body support frame are arranged towards dolly entrance) towards dolly entrance, on the crossbeam 6-1 of this body support frame, be shaped with the fixed head 1 stretching along crossbeam length direction, two ends on this fixed head are respectively equipped with a slide bar 3, one portable plate 5 is installed on two slide bars, on slide bar between portable plate and fixed head, cover has spring 2, while pressing portable plate, portable plate overcomes spring force and moves towards fixed head.
Portable plate is provided with between two lock pin 4(two latches and keeps certain distance towards the one side of valve mechanism), on the upper plate of valve mechanism and lower plate, offer respectively a lockhole 20, on pedestal 14, also offer a lockhole corresponding with the lockhole of upper plate.When circuit breaker trolley does not push, above to win in succession and the substantially parallel layout of lower plate, the lockhole of above winning in succession is aimed at (coaxially arranged) with the lockhole on pedestal, and two lock pins insert respectively in the lockhole of lockhole, upper plate and pedestal of lower plate.
On two parallel support arm 6-2 of this body support frame, be respectively equipped with a slide block 7, the chute 7-1 of each slide block stretches along the length direction of support arm, after having two backstay 6-3 to pass through chute, be positioned on support arm, separately there is one end of a spring 2 to be fixed on slide block, the other end is fixed therein on a positioning rod, one end of slide block is shaped with for promoting the angle 7-3 of described portable plate, and the other end is shaped with the baffle plate 7-2 towards equipment entrance.When circuit breaker trolley extruding baffle plate, two slide blocks move towards portable plate, and under the effect of angle, portable plate moves towards fixed head, and two lock pins depart from lockhole, above win in succession and lower plate release.When circuit breaker trolley exits, slide block resets under the effect of spring, and the spring of slide bar forces portable plate to reset, and above wins in succession and also resets with lower plate, and lock pin inserts in lockhole valve structure is locked.
Described portable plate is parallel with fixed head, and lock pin is parallel with slide bar and perpendicular to portable plate, fixed head and chute.
In figure, also have installing hole 8, bus bar side sleeve pipe 9, outlet casing tube 10, dolly 11, guide post 19.
