Description
Technical field
The utility model relates to a kind of power supply unit field, relates in particular to a kind of circuit breaker locking device simple and reasonable, flexible to operation.
Background technology
In in elevator control cabinet or elevator distribution case, be provided with elevator main circuit breaker, cage illumination sky is opened, and well lighting sky is opened etc., plays the effect that switches on or off the power supply of elevator each several part.Consider for Electrical Safety, GB GB 7588 requires main circuit breaker, sky to open can to list to lock.And locking device requires: off-state can be locked, and on-state can not be locked.Because elevator installation, maintenance, repair and maintenance need, main circuit breaker, illumination sky are opened and should be designed to lock respectively or simultaneously.
Existing common locking device comprises two schemes.A kind of is the small fixture that circuit breaker or the empty supporting lock sky of manufacturer of opening are opened, this small fixture comprises housing and the fixture block that can slide in housing, when use, fixture block front end is connected on circuit breaker toggle, then pulls open fixture block small fixture is fixed on circuit breaker, play the effect of locking.Another kind is, on the circuit breaker of distribution box or control cubicle, mechanism for locking up is set, as a kind of structure of slip, its structure comprises support and locking plate, locking plate can slide up and down on support, is provided with mobile buckling parts at locking plate front end, is provided with fixing buckling parts on support, in the time of needs locking, slide locking plate, make mobile buckling parts and the fixing buckling parts fastening that coincides, play the effect of locking.
But all also there are some defects in this two schemes.In the first scheme, this sky is unblanked small fixture because volume is little, unfixing, easily loses; And lock multiple switches and need to unblank by multiple skies, apply loaded down with trivial details; The specific purpose tool of switch producer design, often can only be applicable to the switch of a brand, and versatility is not strong, lose or damage after be difficult for having bought accessory.In first scheme, on this, lock construction is relatively complicated, and the space taking is also larger.
Summary of the invention
The utility model mainly solved the unreasonable or instrument of existing mechanism for locking up complex structure fixing, easily lose, change and safeguard inconvenient problem, a kind of circuit breaker locking device simple and reasonable, flexible to operation is provided.
The utility model solves the technical scheme that its technical problem adopts: a kind of circuit breaker locking device, comprise the support being arranged between circuit breaker, on described support, be connected with the independent locking plate of controlling, described locking plate comprises the connecting portion and the stop part that are wholely set, connecting portion is connected on support, and stop part extends on circuit breaker.The utility model structure is relatively simple, and processing and fabricating is easy, and it is better convenient to safeguard.This locking plate can be locked or two circuit breakers be locked simultaneously a circuit breaker separately, easy to operate freedom, convenient operation librarian use.
As a kind of preferred version of such scheme, the connecting portion of described locking plate and stop part are rectangular structure, and connecting portion is vertically arranged on support, and connecting portion one end is hinged on support, and stop part is connected with connecting portion is perpendicular, stop that position is on circuit breaker.In this programme, locking plate adopts the structure of stirring, and locking plate becomes T shape or L-type shape.Connecting portion upper end or lower end are hinged on support, in the time not locking, dig locking plate, and in the time will locking, the lower locking plate of lid, allows the stop part of locking plate keep off on the stroke of killer switch.This lock plate structure advantages of simple, handled easily personnel operation.
As a kind of preferred version of such scheme, in the other end of described connecting portion and the opposing side of stop part, be provided with locking plate, described the first locking plate is vertically connected on connecting portion, on locking plate, be provided with the first lockhole, on described support, corresponding locking plate position is provided with latch, on latch, be provided with second lockhole corresponding with the first lockhole, locking bolt penetrates in the first lockhole and the second lockhole, and locking plate is locked on support.In the time that needs are locked, renovate upper collet, now the locking plate on locking plate and latch align, and the first lockhole and the second lockhole also align.If be provided with two locking plates on support, two locking plate one the first from left right sides are positioned at latch both sides, and the common alignment of the first lockhole the second lockhole on two locking plates, uses locking bolt through the first lockhole and the second lockhole, so just locking plate is fixed.
As a kind of preferred version of such scheme, in the one side of circuit breaker, be laterally disposed with some projections at described stop part.This projection makes stop part can better stop the switch of circuit breaker, plays good locking effect.
As a kind of preferred version of such scheme, the stop part of described locking plate is strip, connecting portion is square or toroidal, stop part is laterally connected on connecting portion, in the middle of connecting portion, be provided with through hole, in the middle of support, be provided with the joint pin corresponding with through hole, connecting portion is enclosed within on joint pin, joint pin is provided with the 3rd lockhole, is installed with locking bolt locking plate is fixed in the 3rd lockhole.In this programme, locking plate adopts detachable structure, in the time that needs are locked, and locking plate stop part horizontally set, connecting portion buckles on joint pin, makes like this stop part horizontal on killer switch stroke, plays locking effect.In the time not locking, as long as stop part is vertically arranged, then connecting portion is buckled on joint pin, both the convenient loss that has also prevented locking plate.
As a kind of preferred version of such scheme, the stop part of described locking plate has two, stop part is strip, connecting portion is square or toroidal, stop part symmetry is connected to connecting portion both sides, in the middle of connecting portion, be provided with through hole, in the middle of support, be provided with the joint pin corresponding with through hole, connecting portion is enclosed within on joint pin.Locking plate is made into bilateral locking plate by this programme, while making to lock, can pin the circuit breaker of both sides simultaneously, easy to operate.
As a kind of preferred version of such scheme, the through hole on described connecting portion is square, and the joint pin on described support is the square cylinder structure corresponding with through hole.Through hole and joint pin are all designed to square, make the locking plate can be laterally or perpendicularly place mutually, and after locking plate is locked, can not produce and rock on a large scale and affect the effect of locking.
The utility model has the advantages that: structure is relatively simple, and processing and fabricating is easy, it is better convenient to safeguard.This locking plate can be locked or two circuit breakers be locked simultaneously a circuit breaker separately, easy to operate freedom, convenient operation librarian use.
