Abstract
The invention relates to a switch cabinet, and particularly to a switch cabinet grounded by opening a door. The switch cabinet grounded by opening the door comprises a cabinet body, wherein the cabinet body is rotationally provided with a grounding knife shaft; a grounding knife is fixedly arranged in the middle of the grounding knife shaft; a door lock for locking a lower door is arranged at the end part; the grounding knife shaft rotates to drive the grounding knife to be switched on or off, and the door lock locks or unlocks the lower door correspondingly. The lower door is unlocked while the grounding knife is switched on, so that the switch cabinet is grounded when the lower door is opened. Therefore, the switch cabinet grounded by opening the door can be maintained safely.
Description
Technical field
The present invention relates to a kind of switch cubicle, relate in particular to a kind of earthed switch cabinet that opens the door.
Background technology
Switch cubicle runs into that inner body damages or during the situation such as circuit for generating fault, need to open the Xiamen of switch cubicle inside switch cabinet is keeped in repair, because switch cubicle is high-tension apparatus, if keeped in repair under charged state, once meet accident, its consequence is by hardly imaginable.In like manner, because switch cubicle is high-tension apparatus, when switch cubicle moves, lower cabinet door must in off position, not allow to open.Therefore, just need to guarantee that when opening the door maintenance earthed switch closes a floodgate, prevent from getting an electric shock; During the switch cubicle operation, lower cabinet door must closed, and can not open.Guarantee that above-mentioned two states is a technical barrier so how to make easily the cabinet door.
Summary of the invention
The invention provides a kind of earthed switch cabinet that opens the door of opening cabinet maintenance safety.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:
A kind of earthed switch cabinet that opens the door, comprise cabinet; Rotate the ground connection cutter shaft is set on described cabinet; Described ground connection cutter shaft middle part is fixedly installed earthing, and end arranges the door lock that pins Xiamen; Drive earthing separating brake or combined floodgate along with the ground connection cutter shaft rotates, door lock pins or the release Xiamen accordingly.
Fixedly mount connecting lever on described ground connection cutter shaft; The free end of described connecting lever is hinged on connecting rod;
Also be provided with the power transmission shaft parallel with the ground connection cutter shaft on described cabinet; Fixedly mount crank on described power transmission shaft, the free end of crank is hinged on connecting rod;
Described power transmission shaft and ground connection cutter shaft are positioned on same perpendicular; Crank on described connecting lever and power transmission shaft is parallel to each other all the time;
Also be provided with the operating axis parallel with power transmission shaft on described cabinet; Fixedly mount respectively two curved bars that are parallel to each other on described operating axis and power transmission shaft, the free end of two curved bars is hinged on pull bar.
Beneficial effect of the present invention is: Xiamen release when earthing closes a floodgate, ground connection while opening Xiamen, maintenance safety; By action bars, rotate, chain drivening rod moves up and down, and then drives the ground connection cutter shaft and rotate, and reaches that ground connection is opened the door simultaneously, earth-free purpose of simultaneously locking a door, and action bars can be arranged on the place of other handled easilies of cabinet, handled easily like this.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of earthed switch cabinet that opens the door of the present invention;
The right view that Fig. 2 is Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, a kind of preferred implementation of opening the door the earthed switch cabinet of the present invention is made to detailed description:
As depicted in figs. 1 and 2, Ben Kaimen earthed switch cabinet, comprise cabinet 1, rotates the ground connection cutter shaft 6 of the level that arranges on cabinet 1, and ground connection cutter shaft 6 has two, be parallel to each other in same perpendicular.
Ground connection cutter shaft 6 middle parts are fixedly installed earthing 7, and along with ground connection cutter shaft 6 rotates back and forth 90 °, earthing 7 is respectively in closing a floodgate or open position.One end of ground connection cutter shaft 6 is near the Xiamen 10 of cabinet 1, this end is provided with the door lock 9 that pins Xiamen 10, door lock 9 is a sheet metal, be fixedly mounted on ground connection cutter shaft 6, be provided with accordingly draw-in groove on Xiamen 10, drive earthing 7 separating brakes or combined floodgate along with ground connection cutter shaft 6 rotates, door lock 9 snaps in accordingly or deviates from the draw-in groove on Xiamen 10, thereby pins or release Xiamen 10.
Fixed installation connecting lever 5 on ground connection cutter shaft 6, the free end of connecting lever 5 is hinged on connecting rod 8.Also be provided with the power transmission shaft parallel with ground connection cutter shaft 64 on cabinet 1, on described power transmission shaft 4, fixedly mount crank, the free end of crank also is hinged on connecting rod 8.Power transmission shaft 4 be positioned at ground connection cutter shaft 6 directly over, connecting lever 5 threes on the crank on power transmission shaft 4 and two ground connection cutter shafts 6 are parallel to each other, thereby make connecting rod 8 all the time in vertical state.
Also be provided with the operating axis parallel with power transmission shaft 42 on cabinet 1, operating axis 2 is positioned at the left side of power transmission shaft 4, fixedly mounts respectively two curved bars that are parallel to each other on operating axis 2 and power transmission shaft 4, and the free end of two curved bars is hinged on the two ends of pull bar 3.Curved bar on power transmission shaft 4 is mutually vertical with crank.
When using, during earthing 7 separating brake, door lock 9 is stuck in the draw-in groove of Xiamen 10, and Xiamen 10 can not be opened.In the time of need to opening the Xiamen maintenance, operating axis 2 is rotated counterclockwise to 90 °, thereby make pull bar 3 pull power transmission shaft 4 to be rotated counterclockwise 90 °, and then order about connecting rod 8 and move down, drive ground connection cutter shaft 6 and be rotated counterclockwise 90 °, now earthing 7 closes a floodgate, the draw-in groove that door lock 9 breaks away from Xiamen 10 simultaneously, release Xiamen 10.
