Technical field
The utility model relates to a kind of interlocking device of electric switch, particularly relates to a kind of link gear of the interlocking for solid insulation switch cabinet.
Background technology
At present, in the electric switch field, especially solid insulation switch cabinet field, there are a lot of occasions will use interlocking device, mechanism's main shaft of circuit breaker close a floodgate or during separating brake the lead agency main shaft can only be in combined floodgate angle position or separating brake angle position, is connected by link gear between mechanism's main shaft and the interlock plate, when combined floodgate or separating brake, link gear drives the interlock plate motion, thereby the functional unit of needs interlocking is locked or release.Owing to mechanism's main shaft has certain closing process when closing a floodgate, cause the very large active force of generation between interlock plate and the locating part, affect the accurate of combined floodgate and location.A kind of better simply interlocking principle has appearred in addition at present, can between a plurality of functional units, realize the interlocking of needs, being exactly that an interlock plate is vertical arranges and face forward, the functional unit of needs interlocking vertically is arranged on the rear of interlock plate, interlock plate the place ahead setting operation panel, the position of corresponding each functional unit is provided with handle hole on the guidance panel, some vacancies district is set on the interlock plate, when interlock plate moves to certain position, the certain operations parts are blocked by interlock plate, other are positioned at the vacancy district, the functional unit that is blocked like this can not operate by handle hole, operated exercisable functional unit after, it drives interlock plate and moves to the another location, at this moment other functional units enter the vacancy district and convert operable state to, thereby realize interlocking.The forms of motion of interlock plate can be to rotate, and also can be traveling priority.No matter be rotation formula, or traveling priority form, interlock plate all will have a plurality of location statuss, this just requires the link gear in the interlocking device that the stroke that can hold a plurality of location statuss can corresponding be provided, and present link gear does not have the parts of variable-length, because mechanism's main shaft can only be in two location statuss, link gear also can only be in two location statuss, does not provide the stroke space that a plurality of location statuss need.
The utility model content
The technical problems to be solved in the utility model provides a kind of solid insulation switch cabinet interlocking buffering link gear that can cushion, a plurality of location status strokes can be provided for interlock plate between mechanism's main shaft and interlock plate when closing a floodgate.
The utility model solid insulation switch cabinet interlocking is with cushioning link gear, comprise frame, frame is provided with mechanism's main shaft, be fixedly connected with the first vertical with it connecting lever on the wherein said mechanism main shaft, the first connecting lever is provided with the first Long Circle hole, is plugged with slidably the first connecting pin in the first Long Circle hole;
Comprise that also one is arranged on the interlocking output shaft on the described frame, be fixedly connected with the second vertical with it connecting lever on the described interlocking output shaft, the second connecting lever is provided with the second Long Circle hole, is plugged with slidably the second connecting pin in the second Long Circle hole;
Be connected with buffer between described the first connecting pin and the second connecting pin, the setting party of described buffer is to all perpendicular to the axis of described interlocking output shaft and the axis of mechanism's main shaft, described buffer comprises on guide post, the guide post and slidely connects spring strut, be provided with spring in the spring strut, one end of spring is fixedly connected with guide post, the other end of spring is fixedly connected with adjusts lid, adjusts lid and is threaded on the described spring strut;
Described the first connecting pin is plugged on the described guide post, and described the second connecting pin is plugged on described adjustment and covers; Perhaps described the first connecting pin is plugged on described adjustment and covers, and described the second connecting pin is plugged on the described guide post;
Be fixedly connected with guide vane end stop at the second connecting lever opposite side relative with described buffer on the described frame.
The utility model solid insulation switch cabinet interlocking is with cushioning link gear, and the axis of wherein said interlocking output shaft is mutually vertical with the axis of mechanism's main shaft.
The utility model solid insulation switch cabinet is interlocked and is that with buffering link gear difference from prior art the utility model solid insulation switch cabinet interlocking passes through the first connecting lever successively with the buffering link gear on mechanism's main shaft, the first connecting pin, buffer, the second connecting pin, the second connecting lever is connected to an interlocking output shaft, the side relative with buffer at the second connecting lever on the frame is fixedly connected with guide vane end stop, like this when mechanism's main shaft closes a floodgate, the first connecting lever promotes buffer makes the second connecting lever turn to the guide vane end stop position, and buffer can cushion between mechanism's main shaft and interlocking output shaft.Behind mechanism's main shaft separating brake, buffer is pulled back, make the interlocking output shaft be in certain angle position, at this moment because the spring in the buffer is compressible, so the interlocking output shaft can rotate continuously with the spring in the compression buffer, the interlocking output shaft just can be in a plurality of angle positions like this, thereby the stroke of a plurality of location statuss is provided for interlock plate.It is that connecting pin need to slide to keep the direction of buffer constant along the Long Circle hole because when connecting lever rotates that the Long Circle hole all is set on the first connecting lever and the second connecting lever.
When the utility model solid insulation switch cabinet interlocking is mutual vertical with the axis of the axis of interlocking output shaft in the buffering link gear and mechanism main shaft, needed rack construction trends towards cuboid, more regular, be more convenient for like this setting the position of needed other parts of interlocking device.
Below in conjunction with accompanying drawing the utility model solid insulation switch cabinet interlocking is described further with the buffering link gear.
