Description
Technical field
The utility model relates to switch cubicle manufacturing technology field, especially a kind of drive unit of switch cubicle valve.
Background technology
In the switch cubicle technical field; There is valve the circuit breaker cart chamber between the contact box chamber; Open the moving contact that valve makes circuit breaker through the drive unit that touches valve and engages the entering operating state with the fixed contact of contact box chamber when circuit breaker cart shakes when getting into the service position, the drive unit return of valve drive valve is closed when circuit breaker cart shakes out the entering test position; Existing its valve of most switch cubicle is arbitrarily to draw back by enough hands; Because the indoor fixed contact of contact box is a high-voltage charged body; When circuit breaker cart withdraws from the entering inspecting state in switch cubicle, just might make the people draw back valve carelessly and shock hazard occur, therefore there is potential safety hazard.
The utility model content
The technical problem that the utility model will solve provides a kind of drive unit of switch cubicle valve; Valve drive unit self-locking valve can't be opened in the time of can making circuit breaker cart get into test position or maintenance; Prevent artificial arbitrarily unlatching valve and produce shock hazard, help improving the fail safe of switch cubicle.
For achieving the above object; The technical scheme of the utility model is: comprise two L shaped drive plates up and down; Two L shaped drive plates are provided with also in opposite directions, and an end is articulated in a vertical fixing jointly on the bearing pin of side, circuit breaker cart chamber; The other end of two L shaped drive plates is connected with two valve of switch cubicle through push rod, and it also comprises blocking mechanism, and described blocking mechanism comprises the bearing that fixes with side, circuit breaker cart chamber; Fixing two intervals and vertical first fixed axis and second fixed axis that is provided with on the bearing; Articulate a limiting bracket on first fixed axis, the front end of limiting bracket be positive stop end be in L shaped drive plate below, articulate the driving arm of a front end on second fixed axis by the circuit breaker cart driving; The rear end of driving arm rear end and limiting bracket connects together with mode relatively movably, and the rear end of driving arm also is connected with bearing through extension spring; Circuit breaker cart advances, and the touching driving arm turns clockwise when getting into the service position, and driving arm rear end pulling limiting bracket turns clockwise; Circuit breaker cart is retreated and is broken away from driving arm when getting into test position, and the driving arm rear end is rotated counterclockwise under the effect of extension spring, and the driving arm rear end drives limiting bracket again and is rotated counterclockwise.
Further improve; Said driving arm rear end is provided with a square opening and two convexities up and down; Described two convexities are connected with bearing through two extension springs; The rear end of described limiting bracket is provided with a square plate, and described square plate is enclosed within on the square opening of driving arm rear end, and described square plate and square opening can relatively move.
Further improve, the positive stop end of said limiting bracket is provided with spacing preiection, described spacing preiection be in L shaped drive plate below.
When circuit breaker cart advances the entering service position, can touch driving arm and turn clockwise, driving arm rear end pulling limiting bracket is done and is turned clockwise, and this moment, the positive stop end and the last L shaped drive plate mistake of limiting bracket can't afford to drive position-limiting action, and valve can normally be opened; , circuit breaker cart just breaks away from driving arm when retreating the entering test position; The driving arm rear end is rotated counterclockwise under the effect of extension spring; The driving arm rear end just drives limiting bracket and is rotated counterclockwise like this, this moment limiting bracket positive stop end just forward to L shaped drive plate below, make two L type drive plates can't rotate the realization self-locking in opposite directions; Therefore when circuit breaker cart gets into test position or pulls out maintenance; Valve on the switch cubicle can't be opened, and can effectively prevent the generation of shock hazard, the fail safe that helps improving switch cubicle.

Embodiment
Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further explain.
Fig. 1 is to shown in Figure 5; A kind of drive unit of switch cubicle valve; Comprise two L shaped drive plates 1,2 up and down; Two L shaped drive plates 1,2 are provided with in opposite directions and an end is articulated in a vertical fixing jointly on the bearing pin 3 of 10 sides, circuit breaker cart chamber, and the other end of two L shaped drive plates 1,2 is connected with two valve of switch cubicle through push rod, and described drive unit also comprises blocking mechanism.
Described blocking mechanism comprises the bearing 4 that fixes with 10 sides, circuit breaker cart chamber; Two intervals and vertical first fixed axis 41 and second fixed axis 42 that is provided with are set on the bearing 4; Articulate a limiting bracket 5 on first fixed axis 41; The front end of limiting bracket 5 be positive stop end 51 be in L shaped drive plate 1 below, articulate the driving arm 6 that a front end 61 is driven by circuit breaker cart on second fixed axis 42, the rear end 52 of driving arm 6 rear ends 62 and limiting bracket 5 connects together with mode relatively movably; Be specially on driving arm 6 rear ends 62 and be provided with a square opening 621; The rear end 52 of described limiting bracket 5 is provided with a square plate 521, is enclosed within described square plate 521 on the square opening 621 of driving arm 6 rear ends 62, and described square plate 521 can be relatively moved with square opening 621.
On driving arm 6 rear ends 62, also be provided with two convexities 622,623 up and down, described two convexities 622,623 are connected with bearing 4 through two extension springs 7,8.
The positive stop end 51 of said limiting bracket 5 is provided with spacing preiection 511, described spacing preiection 511 be in L shaped drive plate 1 below.
The operation principle of the utility model is following: when circuit breaker cart advances the entering service position; The front end 61 that can touch driving arm 6 turns clockwise driving arm 6; Thereby the rear end 52 of 52 while of the rear end limiting bracket 5 of the rear end of driving arm 6 62 pulling limiting brackets 5 relatively moves with the rear end 62 of driving arm 6 limiting bracket 5 is turned clockwise; The positive stop end 61 of limiting bracket 5 just staggers with last L shaped drive plate 1; Do not play position-limiting action, two L shaped drive plates 1,2 can rotate in opposite directions and open valve through push rod and make the moving contact on the circuit breaker engage the entering operating state with the fixed contact of contact box chamber this moment; , circuit breaker cart just breaks away from when retreating the entering test position with driving arm 6; Driving arm 6 rear ends 62 are rotated counterclockwise under the effect of two extension springs 7,8; The rear end 62 of driving arm 6 drives limiting bracket 5 again and is rotated counterclockwise; This moment limiting bracket 5 the spacing preiection 511 of positive stop end 51 just forward to L shaped drive plate 1 below; Make two L shaped drive plates 1,2 can't rotate the realization self-locking in opposite directions, further limit opening of valve, just can prevent artificial arbitrarily open valve and produce shock hazard.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection range of this case.
