Description
Technical field
The utility model relates to a kind of handcart switch cabinet, and specifically a kind of handcart switch cabinet carries gate interlock mechanism.
Background technology
Handcart switch cabinet its activity when charging operation can not at will be opened.In order to reach this purpose, gate interlock mechanism is carried in pass, part handcart-type sky cabinet design at present, when the circuit breaker of handcart switch cabinet is drawn out cabinet, carries gate interlock mechanism operation valve and covers switch cubicle with charged position; When the circuit breaker of handcart switch cabinet is pushed into cabinet, to carry gate interlock mechanism operation valve and leave charged position in the switch cubicle, circuit breaker can contact with charged position in the switch cubicle and formed a power circuit this moment.Yet, existing handcart switch cabinet to put forward the gate interlock mechanism structure comparatively complicated, and Interlock Reliability is relatively poor, makes handcart switch cabinet have the potential safety hazard of misoperation, the safety that threatens operating personnel when charged and maintenance.
Summary of the invention
The technical problems to be solved in the utility model provide a kind of make handcart switch cabinet stable and reliable operation, easy to operate handcart switch cabinet carry gate interlock mechanism.
In order to solve the problems of the technologies described above, the utility model is taked following technical scheme:
A kind of handcart switch cabinet carry gate interlock mechanism, comprise the circuit breaker push pedal, go up valve push pedal and valve push pedal down, also comprise fixed head and last lockplate, following lockplate, fixedly be equiped with main shaft on the fixed head, last valve push pedal and following valve push pedal movable set are on main shaft, main shaft is provided with an end and is stuck in the elastic component that valve push pedal, the other end are stuck in down the valve push pedal, and the movable and equal activity of following lockplate of last lockplate is loaded on the fixed head, is provided with spring between last lockplate and following lockplate.
Described go up offer on the lockplate with last valve push pedal on the groove that fastens of fixed leg, offer on the following lockplate with following valve push pedal on the groove that fastens of fixed leg.
The elastic component that clamps with described upward valve push pedal and following valve push pedal is a torsion spring.
The utility model is simple in structure, easy to operate, be widely used in the handcart switch cabinet, by moving of circuit breaker push pedal, can realize moving of valve and following valve, valve can't be opened when making circuit breaker be in the service position, still can open the hidden danger that valve overhauls when stopping the switch cubicle charging operation, guarantee operating personnel's safety, easy to maintenance, make the safe and reliable operation of switch cubicle.
Description of drawings
Structural representation when accompanying drawing 1 is in inspecting state for the utility model;
Status architecture schematic diagram when accompanying drawing 2 is the utility model circuit breaker push pedal motion process;
Accompanying drawing 3 is the structural representation of the utility model when in running order.
Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of handcart switch cabinet carry gate interlock mechanism, comprise circuit breaker push pedal 1, go up valve push pedal 2 and valve push pedal 3 down, also comprise fixed head 4 and last lockplate 5, following lockplate 6, fixedly be equiped with main shaft 7 on the fixed head 4, last valve push pedal 2 and following valve push pedal 3 movable sets are on main shaft 7, main shaft 7 is provided with an end and is stuck in the elastic component 8 that valve push pedal 2, the other end are stuck in down valve push pedal 3, last lockplate 5 activities and following lockplate 6 equal activities are loaded on the fixed head 4, and last lockplate 5 and 6 of following lockplates are provided with spring 9.Offer on the last lockplate 5 with last valve push pedal 2 on the groove 11 that fastens of fixed leg 10, offer on the following lockplate 6 with following valve push pedal 3 on the groove 11 that fastens of fixed leg 10.In addition, be made as torsion spring with described upward valve push pedal 2 with the elastic component 8 that following valve push pedal 3 clamps.The utility model is widely used in the handcart switch cabinet.
When the utility model was in maintenance, as shown in Figure 1, the circuit breaker push pedal did not enter the service position, and circuit breaker disconnects, and handcart switch cabinet is out of service, and operating personnel can safe overhauling switch cubicle.At this moment, groove on the last lockplate sticks the fixed leg of valve push pedal, groove on the following lockplate sticks down the fixed leg of valve push pedal, make valve push pedal and following valve push pedal relative fixed, can't directly promote the last valve and the following valve of handcart switch cabinet, switch cubicle is out of service when guaranteeing that operating personnel overhaul, and guarantees operating personnel's safety.
As shown in Figure 2, the process that the circuit breaker push pedal is moved to the service position, the circuit breaker push pedal promotes lockplate and following lockplate simultaneously, last lockplate is that the center clockwise rotates with the attachment positions of itself and fixed head, fixed leg in groove on the last lockplate and the last valve push pedal breaks away from, and makes lockplate no longer stick the valve push pedal; Following lockplate is that the center rotates counterclockwise with the attachment positions of itself and fixed head, and the fixed leg disengaging in the groove on the following lockplate and the following valve push pedal makes down lockplate no longer stick down the valve push pedal.
Circuit breaker continues to advance and the arrival service position toward the service position, as shown in Figure 3, circuit breaker is in continuing the process that advances, fixed leg in the promotion in valve push pedal and the following valve push pedal, torsion spring is compressed, last valve push pedal is that the center clockwise rotates with the main shaft, and last valve push pedal moves up and avoids the contact of circuit breaker push pedal; Following valve push pedal is that the center rotates counterclockwise with the main shaft, and following valve push pedal moves down the contact of avoiding the circuit breaker push pedal, goes up lockplate simultaneously and continues to clockwise rotate, and following lockplate continues to rotate counterclockwise, and spring is stretched.When finally moving to the service position, the circuit breaker push pedal goes up valve push pedal and following valve push pedal relative fixed, at this moment closing of power circuit breaker.When needing interruption maintenance, only need pull out the circuit breaker push pedal, the pulling force that last lockplate and following lockplate are subjected to spring automatically resets, and the elastic force that last valve push pedal and following valve push pedal are subjected to torsion spring automatically resets to the origin-location, and is easy to operate.
Need to prove that under the prerequisite that does not break away from inventive concept of the present utility model, any show and the replacement seen are all within protection range of the present utility model.
