Abstract
The utility model belongs to the field of switch equipment, and in particular to a switch operation interlocking mechanism. A driving device for the switch operation interlocking mechanism comprises a rotating mechanism arranged inside a mechanism box, a worm gear, a worm and a travel plate, wherein the travel plate is fixed on a spindle of a grounding switch; the rotating mechanism is connected with the worm by a universal joint; the worm is matched with the worm gear; a push rod is fixed on the end face of the worm gear; and the travel plate is provided with a travel space, in which the push rod is inserted. The driving device for the switch operation interlocking mechanism has the advantages that the original bevel gear driving is replaced with the cooperated driving of the worm gear and worm and the operations of the rotating mechanism and the switching spindle of a flashboard can be performed at different positions so that the operation is convenient; meanwhile, the phenomenon of gear sliding or mechanism deformation can be avoided, and the stability of the equipment is improved.
Description
Technical field
The utility model belongs to the switchgear field, specifically a kind of switching manipulation interlocking device.
Background technology
The operation interlocking mechanism of switchgear is one of critical piece of switch, also be the key component that security incident the most easily occurs, such as misoperation, deformation, interlocking inefficacy etc., personal electric shock system short-circuit occur very easily, even the accident such as blast, cause large-area power-cuts.
The effect of switching manipulation interlocking device is, earthed switch in the switch cubicle is closed a floodgate and sub-switching operation, while interlocks with the circuit breaker in the switch cubicle, prevent charged splice grafting ground switch, prevent from being with ground connection to close circuit breaker and send electricity, thereby guarantee the fail safe that the switch cubicle line maintenance is safeguarded, prevent that the person from getting an electric shock and the generation of system short-circuit accident.
Present switch-cabinet grounding operation interlocking mechanism adopts bevel gear transmission mechanism, and without deceleration device, operating physical force is large, is prone to slip teeth or deformation, causes carrying out the ground connection operation; Operating mechanism and grounding switch main shaft must be in the same horizontal line, otherwise can't connection for transmission, lack flexibility; Interlocking device is hard interlocking, because operating physical force is large, very easily damages locking part, causes interlocking to lose efficacy; The indication of machinery-free type position, ground state is undistinct; Like this, cause accident with regard to very easily causing the fault such as misoperation, mechanism damage, interlocking inefficacy.
Summary of the invention
This practical problem that will solve provides a kind of slip teeth phenomenon, the indeformable earthed switch operation of mechanism stable driving mechanism of not existing.
The utility model provides following technical scheme:
The drive unit of switching manipulation interlocking device, it comprises rotating mechanism and worm gear, worm screw and the stroke plate of being located in mechanism's casing, the stroke plate is fixed on the main shaft of earthed switch, rotating mechanism is connected with worm screw by universal joint, worm and wheel cooperates, fix a push rod on the end face of worm gear, the stroke plate is provided with the stroke space, and push rod inserts in the stroke space.
Described rotating mechanism comprises dwang and drive link, and dwang is connected by the transmission universal joint with drive link, and drive link is connected with described worm screw by described universal joint.
Described stroke space is the arc hollow slots on the stroke plate.
Described stroke space is the arcuate guide groove on the stroke plate.
The utility model has the advantages that cooperating driving to replace original bevel gear by worm and gear drives, operation is rotated can be in different positions from the flashboard rotating shaft, easy to operate, the phenomenon of slip teeth or deformation can not appear in the while, has improved the stability that equipment uses.

Embodiment
As shown in Figure 1, the drive unit of switching manipulation interlocking device, it comprises rotating mechanism and worm gear 5, worm screw 4 and the stroke plate 8 of being located in mechanism's casing 1, stroke plate 8 is fixed on the main shaft 7 of earthed switch, and main shaft 7 is connected with flashboard 6 in the earthed switch mechanism, and rotating mechanism is connected with worm screw 4 by universal joint, worm screw 4 cooperates with worm gear 5, fix a push rod 5a on the end face of worm gear 5, stroke plate 8 is provided with the stroke space, and push rod 5a inserts among the stroke space 8a; Wherein rotating mechanism comprises dwang 2 and drive link 3, and dwang 2 is connected by the transmission universal joint with drive link 3, and drive link 3 is connected with described worm screw 4 by described universal joint; Wherein, stroke space 8a is the arc hollow slots on the stroke plate, also can be the arcuate guide groove.
Rotated dwang 2, carry out transmission by drive link 3, worm screw 4 again, with the rotatory force transmission to worm gear 5, push rod 5a is fixed on can be movable in the 8a of stroke space on the worm gear 5, by contacting of 8a two ends, stroke space and push rod 5a, make stroke plate 8 produce not in the same way position rotation, thereby arrive the not in the same way rotation of position of main shaft 7, realize the combined floodgate of flashboard 6 and the work of separating brake; Wherein the rotation of stroke plate 8 drives the shift in position of direction board pull rod device 8b, shows the information different from separating brake of closing a floodgate thereby drive direction board, has guaranteed the safety of switch-cabinet grounding.
