Background technology
When the circuit breaker cart of GFC switch cubicles is operated, shaken using Worm gear mechanism into the scheme shaken out, to realize open circuit
The switching of device testing position and station position in cabinet, must prevent a kind of dangerous situation in equipment operation：I.e. in open circuit
Under device handcart combined floodgate electriferous state, the danger of switch cubicle is pulled out from operating position.This situation will cause accident, jeopardize work people
The life security of member.In order to prevent powered maloperation, the cooperation of worm gear Yao Jin mechanisms and breaker is installed on circuit breaker cart
Interlock, reliable interlocking is realized, with support personnel and the safety of equipment, at present, existing GFC switch cabinet handcarts are old-fashioned electricity
Magnetic mechanism oil-minimum breaker, as the existing oil-minimum breaker of the continuous development of primary cut-out is slowly replaced by vacuum circuit breaker,
Due to vacuum circuit breaker small volume, its interlocked operation is typically controlled using electric interlock, and electric interlock is confined to secondary circuit
Power supply, being interlocked when secondary side has a power failure to realize.
The content of the invention
The purpose of this utility model seeks to provide a kind of interlocking mechanism of GFC handcarts worm gear Yao Jin mechanisms, using machinery
Interlock method, it is simple to operate, do not limited by secondary circuit, shaken into position and interlocked with breaker worm gear by baffle plate, when disconnected
When road device is in gate-dividing state, baffle plate can just be depressed, and carry out worm gear and shake into operation is shaken out, avoid circuit breaker cart and closing a floodgate
Operated under electriferous state, it is safe and reliable.
For achieving the above object, technical solution adopted in the utility model is：
A kind of interlocking mechanism of GFC handcarts worm gear Yao Jin mechanisms, it includes handle, baffle plate, guide plate I, guide plate II, connection
Locking bar I, spring, joint I, flap, location-plate, blocking lever II, guide plate III, joint II, breaker major part pin, baffle plate setting exist
The outside of worm screw, handle are fixedly connected with baffle plate, and guide plate I, guide plate II, guide plate III, positioning are fixedly connected with handcart
Plate, the upper end of blocking lever I are fixedly connected through guide plate I with baffle plate, and the lower end of blocking lever I is connected through guide plate II with joint I,
The both ends of joint I, the lower end of joint II and flap are hinged, and are hinged in the middle part of flap with location-plate bottom, the upper end of joint II and connection
Locking bar II connects, and blocking lever II passes through guide plate III, and breaker major part pin is arranged on the surface of blocking lever II, breaker closing
When breaker major part pin be in low-level position, stop that blocking lever II shifts up；Spring is provided with described blocking lever I,
Spring upper end is fixedly connected with blocking lever I, and lower end is connected with guide plate II.
Described guide plate I, guide plate II, guide plate III are the angle block of right angle with vertical pilot hole, guide plate I,
Guide plate II gives the movement through the blocking lever I of its pilot hole to be oriented to, and guide plate III is to the blocking lever through its pilot hole
II is oriented to.
Described spring is stage clip, and plain washer is fixedly installed on blocking lever I, and spring is in plain washer and guide plate II
Between position, give blocking lever I 1 upward thrusts all the time, help be connected with blocking lever I baffle plate reset, shelter from worm screw.
The course of work of the present utility model is：When breaker is in cabinet testing position, it is necessary to first by breaker open operation, divide
During lock, breaker major part pin is in a separating brake high position, and at this moment operating personnel press downwards handle with hand, drives baffle plate, blocking lever I, connects
First I moves downward, and spring is in plain washer and the centre position of guide plate II, by compressed energy-storage, now by flap, location-plate, pin
The lever rotation mechanism of composition, rotated counterclockwise under downward active force driving, make joint II drive blocking lever II to transport upwards
Dynamic, after breaker open operation, it is high-order that breaker major part pin is in diagram separating brake, the movement travel of its blocking lever I, allows baffle plate enough
Releasing is moved downward to block worm screw, at this moment handle can be inserted worm screw by operating personnel, circuit breaker cart shake into
Operation, shakes and proceeds to operating position.
Breaker is shaken to operating position, removes worm screw operation handle, because spring is by energy storage, under the driving of spring,
Blocking lever I and baffle plate automatically reset upward motion, shelter from worm screw.
When carrying out closing operation to breaker, breaker major part pin is in combined floodgate low level, against the upper of firmly blocking lever II
End, cause now press handle downwards, also just do not operate worm screw.Avoid what breaker was shaken out in closing position
Risk, it is necessary to first separating brake, circuit breaker cart could be shaken out, ensure that safety.
The beneficial effects of the utility model are：
By the interlocking mechanism of GFC handcart worm gear Yao Jin mechanisms, use that can be to worm screw is effectively limited, and passes through thick stick
Rod principle realizes interlocking, does not change former handcart structure, and can just be shaken only after breaker open operation into shaking out cabinet, it is ensured that dimension
The security of maintenance is protected, and it is simple in construction, and easy to operate, security performance is high.
Brief description of the drawings
Fig. 1 is structural representation of the embodiment of the present invention；
Fig. 2 is Fig. 1 partial structural diagrams.
Embodiment
A kind of interlocking mechanism of GFC handcarts worm gear Yao Jin mechanisms as shown in drawings, it includes handle 2, baffle plate 3, is oriented to
Plate I 4, guide plate II 7, blocking lever I 5, spring 6, joint I 8, flap 9, location-plate 10, blocking lever II 11, guide plate III 12, connect
First II 16, breaker major part pin 13, baffle plate 3 are arranged on the outside of worm screw 1, and handle 2 is fixedly connected with baffle plate 3, fixed in handcart
Guide plate I 4, guide plate II 7, guide plate III 12, location-plate 10 are connected with, the upper end of blocking lever I 5 passes through guide plate I 4 and baffle plate
3 are fixedly connected, and the lower end of blocking lever I 5 is connected through guide plate II 7 with joint I 8, joint I 8, the lower end of joint II 16 and flap 9
Both ends are hinged, and the middle part of flap 9 is hinged with the bottom of location-plate 10, and the upper end of joint II 16 is connected with blocking lever II 11, blocking lever
II 11 pass through guide plate III 12, and breaker major part pin 13 is arranged on the surface of blocking lever II 11, breaker during breaker closing
Major part pin 13 is in low-level position, stops that blocking lever II 11 shifts up；Spring 6, bullet are provided with described blocking lever I 5
The upper end of spring 6 is fixedly connected with blocking lever I 5, and lower end is connected with guide plate II 7.
Described guide plate I 4, guide plate II 7, guide plate III 12 are the angle block of right angle with vertical pilot hole, are oriented to
Plate I 4, guide plate II 7 give the movement through the blocking lever I 5 of its pilot hole to be oriented to, and III 12 pairs of guide plate passes through its pilot hole
Blocking lever II 11 be oriented to.
Described spring 6 is stage clip, and plain washer 15 is fixedly installed on blocking lever I 5, and spring 6 is in plain washer 15 and led
To the centre position of plate II 7, give blocking lever I 51 upward thrusts all the time, the baffle plate 3 for helping to be connected with blocking lever I 5 resets, and hides
Block worm screw 1.
When breaker is in cabinet testing position, it is necessary to first by breaker open operation, breaker major part pin 13 is in separating brake
