Description
Technical field
The utility model relates to a kind of interlock of switchgear, specifically is valve locking device in the armored withdraw type metal enclosed switchgear.
Background technology
Valve in the existing armored withdraw type metal enclosed switchgear is along with the propelling of circuit breaker dolly or other function dolly and withdraws from, the last 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 realize merely that dolly advances valve to open, and dolly withdraws from valve and cuts out.Not locking of valve when dolly withdraws from, can be artificially push-and-pull valve up and down, thereby open the sleeve pipe connector of a bus, under the charged situation of bus bar side, very easily cause electric shock accidents.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, valve locking device in a kind of armored withdraw type metal enclosed switchgear is provided, this locking device can be realized automatically locking of valve, and has characteristics simple in structure, that installation is simple, easy to use.
The technical solution adopted in the utility model is:
Valve locking device in the armored withdraw type metal enclosed switchgear, it is characterized in that: described locking device is between valve mechanism and equipment inwall, comprise this body support frame of door font that is fixed on the described equipment inwall, the opening of this this body support frame is arranged towards the dolly entrance, be shaped on the fixed head that stretches along the crossbeam length direction on the crossbeam of this body support frame, by two slide bars one portable plate is installed on this fixed head, be with spring on the slide bar between portable plate and the fixed head, portable plate is provided with two lock pins towards the one side of valve mechanism, offer a lockhole on the upper plate of valve mechanism and the lower plate respectively, also offer a lockhole corresponding with the lockhole of upper plate on the pedestal, two lock pins insert the lockhole of lower plate respectively, in the lockhole of upper plate and pedestal; Be respectively equipped with a slide block on two parallel support arms of this body support frame, the chute of each slide block stretches along the length direction of support arm, be positioned on the support arm after having two backstays to pass through chute, other has an end of a spring to be fixed on the slide block, the other end is fixed therein on a positioning rod, one end of slide block is shaped on for the angle that promotes described portable plate, and the other end is shaped on 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 utility model is:
Push in the cupboard process at dolly, dolly push pedal 11 at first contacts with the slide block 7 of this locking device, the slide block pushing tow portable plate 5 of thrust unit makes it move along slide bar 3, 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, the dolly push pedal just contacts with upper plate gear shaft 12, lower plate gear shaft 13 then, promotes upper plate 15, lower plate 16 and then promotes to go up valve 18, following valve 17.When dolly withdraws from, the dolly push pedal at first with valve mechanism on, the lower plate gear shaft separates, the last lower plate of valve mechanism resets under the effect of spring 2, on, following valve resets, block sleeve opening, isolate live part, then the dolly push pedal separates 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, with last lower plate and the locking of connecting plate pedestal of valve mechanism, going to promote up and down so artificially, valve can't promote again, have only the locking device compulsive unlocking, just can so that on, following valve slides up and down under the situation that does not have dolly to push.
The beneficial effects of the utility model are: valve locking device is for automatically locking at the armored withdraw type metal enclosed indoor valve of switchgear circuit breaker in the armored withdraw type metal enclosed switchgear, avoiding after circuit breaker dolly or other function dolly are extracted out, maintenance or cleaning worker are opened valve without authorization and are got an electric shock; Characteristics are: 1. simple in structure, need not to transform the original structure of switch cubicle and structure; 2. install simply, only need stamp two holes at original valve mechanism and just can install, realize function; 3. the lock function of valve can automatically terminate along with the propelling of circuit breaker dolly or other function dolly, along with circuit breaker dolly or withdrawing from of other function dolly and automatically lock; 4. can realize compulsive unlocking function.

Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, valve locking device in the armored withdraw type metal enclosed switchgear is arranged between valve mechanism and the equipment inwall, and two valve mechanisms respectively dispose a locking device.
Each locking device comprises this body support frame of door font 6 that is fixed on the described equipment inwall, the opening of this this body support frame is arranged (two parallel leg that are this body support frame are arranged towards the dolly entrance) towards the dolly entrance, be shaped on the fixed head 1 that stretches along the crossbeam length direction on the crossbeam 6-1 of this body support frame, two ends on this fixed head are respectively equipped with a slide bar 3, one portable plate 5 is installed on two slide bars, be with spring 2 on the slide bar between portable plate and the fixed head, when 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 towards the one side of valve mechanism and keeps certain distance), offer a lockhole 20 on the upper plate of valve mechanism and the lower plate respectively, also offer a lockhole corresponding with the lockhole of upper plate on the pedestal 14.When the circuit breaker dolly does not push, on win in succession and the substantially parallel layout of lower plate, on the lockhole of winning in succession aim at (coaxial arrangement) with the lockhole on the pedestal, two lock pins insert respectively in the lockhole of lockhole, upper plate and pedestal of lower plate.
Be respectively equipped with a slide block 7 on two parallel support arm 6-2 of this body support frame, the chute 7-1 of each slide block stretches along the length direction of support arm, be positioned on the support arm after having two backstay 6-3 to pass through chute, other has an end of a spring 2 to be fixed on the slide block, the other end is fixed therein on a positioning rod, one end of slide block is shaped on for the angle 7-3 that promotes described portable plate, and the other end is shaped on the baffle plate 7-2 towards equipment entrance.When circuit breaker dolly extruding baffle plate, two slide blocks move towards portable plate, and portable plate moves towards fixed head under the effect of angle, and two lock pins break away from lockholes, on win in succession and the lower plate release.When the circuit breaker dolly withdrawed from, slide block resetted under the effect of spring, and the spring of slide bar forces portable plate to reset, on win in succession and lower plate also resets, lock pin inserts in the lockhole valve structure is locked.
