A kind of busway inserting case interlocking gear
The present invention relates to transmission equipment accessory, specifically a kind of for jack box and bus duct are carried out to the jack box interlocking gear of safe combined floodgate and separating brake by the operating grip on jack box.
Jack box, as a functional unit of power transmission busbar, plays a part to distribute electric energy in bus duct system.The mode of operation of jack box is a lot, after jack box is inserted on bus duct, guarantee that jack box can reliably be connected with bus duct and safety, easily separating brake with close a floodgate most importantly, this will be directly connected to the operation that can jack box reliably and with long-term.At present, generally adopt the mode of rotary switch and operating grip to realize energising and the power-off of jack box and bus duct, this just need to arrange attachable fixing point on bus groove case and jack box housing, and it operates inconvenience, and not attractive in appearance, and mechanism is complicated.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of busway inserting case interlocking gear, this interlocking gear is simple in structure, manufacture and easy for installation, be connected firmly, simple operation.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of busway inserting case interlocking gear, comprise operating grip, cursor, switch bar assembly, link assembly, wherein, described cursor is fixed on described switch bar assembly two ends and becomes with it " U " shape structure, described cursor bottom is connected with described link assembly by connector, described link assembly comprises cross bar and montant, described cross bar one end is fixed on connector, the other end is fixed on montant, described montant bottom is provided with alignment pin, described operating grip is provided with cam pack, described cam pack is a hollow annulus, its outside is provided with a projective structure, described cam pack is bolted on the outside of described cursor.
Above-mentioned a kind of busway inserting case interlocking gear, wherein, described alignment pin is parallel with cross bar.
Beneficial effect of the present invention is: this device is by operating grip, cursor, switch bar assembly, link assembly is connected, when rotating operation handle, drive cam pack to rotate, cam pack drives cursor to rotate, cursor drives switch bar assembly and link assembly to move simultaneously, the alignment pin of link assembly bottom will rotate certain angle thereupon like this, make alignment pin block bus duct part, realizing jack box cannot extract under "on" position, thereby improved the fail safe of jack box when energising use procedure, simple in structure, simple operation, safety and stability, protected staff's personal safety.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention
Fig. 2 is the cutaway view of A-A of the present invention
A kind of busway inserting case interlocking gear as shown in the figure, comprise operating grip 1, cursor 2, switch bar assembly 3, link assembly 4, described cursor 2 is fixed on described switch bar assembly 3 two ends and becomes with it " U " shape structure, described cursor 2 bottoms are connected with described link assembly 4 by connector 5, described link assembly 4 comprises cross bar 41 and montant 42, described cross bar 41 one end are fixed on connector 5, the other end is fixed on montant 42, described montant 42 bottoms are provided with alignment pin 6, described alignment pin 6 is parallel with cross bar 41, described operating grip 1 is provided with cam pack 11, described cam pack 11 is a hollow annulus, its outside is provided with a projective structure 12, described cam pack 11 is fixed on the outside of described cursor 2 by bolt 13, described operating grip 1 is provided with rotating shaft 10, described rotating shaft 10 is fixed on busway inserting case outer wall 7 through cam pack 11 is rotating, described operating grip 1 is connected by buckle 9 with cam pack 11, described switch bar assembly 3 is provided with switch card article 31, for blocking the knob of switch 8.
During normal condition, the projective structure of operating grip points to " OFF " shelves, when needs are switched on, operating grip dextrorotation is gone to " ON " shelves, now operating grip drives cam pack rotation, and cam pack drives cursor to be rotated counterclockwise, and switch bar assembly starts to rotate counterclockwise thereupon, due to switch card article clamping switching knob, make switch turn to " ON " shelves by " OFF " shelves, realize and closing a floodgate, start energising.When cursor rotates counterclockwise; connector drivening rod assembly turns clockwise; the alignment pin of link assembly bottom will clockwise rotate certain angle thereupon like this; bus duct between jack box and alignment pin can be blocked; jack box can not come off under "on" position; thereby improved the fail safe of jack box when energising use procedure, protected staff's personal safety.
Here description of the invention and application is illustrative, not wants that therefore, the present invention is not subject to the restriction of the present embodiment by scope restriction of the present invention in the above-described embodiments, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
