The utility model is characterized in that an interlocking device is further provided, which comprises a latch hook swinging block driving a latch hook of the cabinet door locking mechanism swing, a bolt swinging block driving a bolt of the separator locking mechanism swing and a base fixed on a cabinet frame of a high voltage switchgear. The base is provided with a bottom plate and a side plate. The latch hook swinging block is rotatably fixed on the bottom plate and the bolt swinging block is movably fixed on the side plate. Compared with the existing technology, the utility model has the advantages that the separator locking mechanism links with the cabinet door locking mechanism, a separator or cabinet door can be opened only when the cabinet door is fully closed or the separator is fully inserted into the separating position, which is safe and reliable.
Description
The utility model relates to a kind of mechanical interlock mechanism.
Existing the high-voltage switch gear electricity cashier's office in a shop be used to lock the cabinet door with temporarily with electric cabinet in separated by spaces become live zone, the mechanical interlock mechanism of the dividing plate of neutral area mainly decides mechanism by diaphragm locking mechanism that acts on separately respectively and cabinet door lock and constitutes, during work, the cabinet door of neutral area is closed and is separated live zone in closing electric cabinet, when the dividing plate of neutral area is in spaced-apart locations, diaphragm locking mechanism, cabinet door lock is decided mechanism and all is in unlocking condition, at this moment, if open the cabinet door, being installed in latch on the diaphragm locking mechanism on the cabinet frame breaks away from the stopping means on the cabinet door and discharges, be inserted in the lockhole on the dividing plate, dividing plate can not be moved from spaced-apart locations, like this, guaranteed to enter the personnel's that work the neutral area safety; After close the cabinet door, extracting dividing plate out, the space all becomes live zone in the cabinet, being installed in the hook that the cabinet door lock of being suppressed by dividing plate on the cabinet frame decides in the mechanism discharges, be buckled in the cabinet door lock that is installed on the cabinet door and decide buckling in the mechanism, the cabinet door can not be opened, prevent that people from entering in the high-voltage switch gear electricity cabinet.This kind mechanical interlock mechanism is because diaphragm locking mechanism and cabinet door lock decide mechanism acts on separately, and, stopping means on the diaphragm locking mechanism is progressive to the effect of latch, occurring the cabinet door does not easily close fully, the cabinet door lock that is positioned on the cabinet door is decided buckleing on the position that also no show cabinet frame is risen to the bait in the mechanism, latch has been in lockset position of coupler, and cabinet door, dividing plate all can be opened, and people can enter in the high-voltage switch gear electricity cabinet that live zone communicates with the neutral area by the cabinet door; In addition, cabinet door lock decide mechanism to unblank be by dividing plate compacting hook, buckleing on the hook disengaging cabinet door realized, and dividing plate is omnidistance to the compacting of hook, in dividing plate was inserted into high-voltage switch gear electricity cabinet, even fully live zone, neutral area are not separated, hook was pressed, buckleing from the cabinet door spins off, and the cabinet door can be opened.
Goal of the invention of the present utility model is to provide a kind of diaphragm locking mechanism, cabinet door lock to decide the mechanism interlock, and the cabinet door is closed or dividing plate when being inserted into spaced-apart locations fully fully, anti-misoperation that dividing plate or cabinet door just can be opened, safe and reliable interlocking device.
The utility model is to realize like this, comprise that cabinet door lock decides mechanism, diaphragm locking mechanism, its special feature is also to be provided with interlock, interlock mainly decide the latch hook swinging block of the latch hook swing in the mechanism, drive the latch swinging block that the latch on the diaphragm locking mechanism swings, the pedestal that is fixed on the high-tension switch cabinet cabinet frame constitutes by driving by cabinet door lock, pedestal is provided with base plate and side plate, the latch hook swinging block rotates and is actively socketed on the base plate, and the latch swinging block is actively socketed on the side plate.
During work, the cabinet door of neutral area is closed and is separated live zone in closing electric cabinet, when the dividing plate of neutral area is in spaced-apart locations, buckleing on the cabinet door with the latch hook hook that the latch hook swinging block is fixed together, the latch that is fixed together with the latch swinging block also is inserted on the pin clamp on the dividing plate, the latch hook swinging block, the latch swinging block all can freely swing, drive latch hook separately, latch swing and disengaging are buckled accordingly, pin clamp, at this moment, if open the cabinet door, cingulum moveable lock hook swing on the cabinet door, break away from button until latch hook, the cabinet door is opened, the latch hook swinging block with latch hook swing to the latch swinging block below, make the latch swinging block can not be toward lower swing, make latch break away from pin clamp on the dividing plate toward lower swing, dividing plate can not be extracted out from high-voltage switch gear electricity spaced-apart locations cashier's office in a shop with swinging block; If the cabinet door is closed, with dividing plate when high-voltage switch gear electricity spaced-apart locations is cashier's office in a shop extracted out, pin clamp drives the latch swing, break away from pin clamp until latch, at this moment, the latch swinging block down swings to the side of latch hook swinging block with latch, and the latch hook swinging block can not be swung, make the pulling lower swing of buckleing that latch hook can not be on the cabinet door, the cabinet door can not be opened.
Here, for when closing the cabinet door, button can drive the latch hook swing swimmingly and firmly be hooked by latch hook, buckles when opening the cabinet door and can drive latch hook swing and the final latch hook that breaks away from swimmingly, and it is forked that latch hook is, and outer fork is short, and interior fork is long, and button is side U word shape.
For when extracting dividing plate, pin clamp can drive latch swing and the final latch that breaks away from swimmingly, when inserting dividing plate, pin clamp can drive the latch swing again swimmingly and finally make latch be positioned in the pin clamp firmly, it is forked that pin clamp is, and outer fork is long, and interior fork is short.
For can being positioned at following of the effect that does not have external force, latch, latch hook open or close two limits, between latch swinging block and pedestal, be provided with tension spring between latch hook swinging block and pedestal.During work, under the effect of tension spring, latch swinging block, latch hook swinging block only are positioned at separately on one of them limit, rotate latch swinging block, latch hook swinging block, when tension spring is crossed the fulcrum (being the dead point) of swinging block, latch swinging block, latch hook swinging block quicken to rotate under the effect of tension spring, till the limit that forwards to separately.
In order to limit the oscillating stroke of latch swinging block, latch hook swinging block, guide groove is being set respectively on the pedestal bottom plate, on the base side boards, the projection that matches with guide groove is set on latch swinging block, latch hook swinging block.
The utility model compared with the prior art, owing to adopted interlock, after cabinet door or dividing plate are put in place fully, latch swinging block or latch hook swinging block could be swung, corresponding dividing plate or cabinet door just can be opened, and therefore, the utlity model has diaphragm locking mechanism, cabinet door lock and decide that mechanism links, the cabinet door is closed or dividing plate when being inserted into spaced-apart locations fully fully, and dividing plate or cabinet door are that just can open, safe and reliable advantage.
