Description
Technical field
The present invention relates to a kind of lock, particularly a kind of transformer station 10KV middle-placed switch cabinet handcart shifts out safety protection lock after cabinet.
Background technology
At present, in transformer substation switch room, when to when wheelbarrow switch overhauls in middle-placed switch cabinet, need cabinet wheelbarrow switch in middle-placed switch cabinet being shifted out middle-placed switch cabinet, now in middle-placed switch cabinet, the fixed contact box baffle plate of switch can fall automatically, ensures that charged fixed contact is not exposed.If but at this moment the control link of middle-placed switch cabinet cabinet sidewall is surprisingly pressed by maintainer, charged fixed contact will be all exposed, state is abnormally dangerous, or middle-placed switch cabinet wheelbarrow switch is surprisingly advanced in middle-placed switch cabinet by non-working person, just there will be serious accident.So under the state of transformer station's central switch cabinet after wheelbarrow switch shifts out cabinet, guarantee that wheelbarrow switch is not advanced switch static contact box baffle plate in middle-placed switch cabinet and middle-placed switch cabinet not opened by unexpected by unexpected misoperation by mistake, be related to the safety of maintainer and the safe operation of transformer station, of crucial importance.
Summary of the invention
Technical problem to be solved by this invention is: the safety protection lock after providing a kind of transformer station middle-placed switch cabinet wheelbarrow switch to shift out cabinet, can, after the handcart of middle-placed switch cabinet shifts out cabinet, prevent unexpected misoperation from causing the person and equipment breakdown.This cover lockset is locked by link lock and handcart and is formed, and link lock is locked by handcart and realized mechanical latching (being realized by its key of its locking).
The technical solution adopted for the present invention to solve the technical problems is: design a set of lock device.The control link that two movable is had on the both sides of transformer station's central switch cabinet cabinet madial wall, it and wheelbarrow switch advance fixed contact box baffle plate in the rail plate of middle-placed switch cabinet and middle-placed switch cabinet to have structure driven to be connected, if control any one in these two movable rods, the pinning as long as an arbitrary exactly connecting rod is fixed, then in middle-placed switch cabinet, fixed contact box baffle plate also cannot be moved and opens, the connecting rod in middle-placed switch cabinet is pinned with middle-placed switch cabinet link lock key, take middle-placed switch cabinet link lock key away, this key to be placed in the handcart lock on the handcart shifted out in middle-placed switch cabinet link lock key lockhole, middle-placed switch cabinet link lock key is pinned while pinning handcart with the lock on handcart, take handcart lock key away.The present invention is by handcart, handcart is locked, moving contact, middle-placed switch cabinet link lock key, middle-placed switch cabinet link lock, curtain door connecting rod, curtain door, cabinet, handcart lock dead bolt reference column, handcart lock dead bolt handle, handcart lock key and lockhole, middle-placed switch cabinet link lock key and lockhole, lock body and dead bolt composition, in middle-placed switch cabinet link lock, middle-placed switch cabinet link lock key is connected with middle-placed switch cabinet link lock lock core of lock head connector, middle-placed switch cabinet link lock lock core of lock head connector is connected with middle-placed switch cabinet link lock lock shaft, middle-placed switch cabinet link lock driving member is enclosed within middle-placed switch cabinet link lock lock shaft, middle-placed switch cabinet link lock driving member is connected with middle-placed switch cabinet link lock dead bolt, middle-placed switch cabinet link lock dead bolt is connected with middle-placed switch cabinet connecting rod locking lock pin.It is characterized in that: the outer side-lower of handcart has handcart to lock, handcart inside front has the moving contact of switch, middle-placed switch cabinet link lock key skewer enters in the lockhole of middle-placed switch cabinet link lock, middle-placed switch cabinet link lock is fixed on curtain door connecting rod, curtain door connecting rod is connected with curtain door, curtain door is connected with cabinet, handcart dead bolt reference column is connected with one end of dead bolt handle, the other end of dead bolt handle is connected with dead bolt, dead bolt handle there is linear gear, dead bolt handle inserts in lock body, middle-placed switch cabinet link lock key inserts in the lockhole of middle-placed switch cabinet link lock key, handcart lock key and lockhole are connected with the linear gear on dead bolt handle by Knucle-gear, middle-placed switch cabinet link lock key and lockhole are connected with dead bolt handle.
Owing to adopting technique scheme, the advantage that the present invention has and good effect are: structure is simple, economical and practical.
