Description
Technical field
The utility model relates to the switch of appliance field, particularly relates to a kind of safety operation device that is used for the air type conversion separation switch of high-voltage explosion-proof electromagnetic starter under the coal mine.
Background technology
At present, the unit switch that is used under the coal mine generally has a plurality of isolating switches, according to GB3836 and safety of coal mines supervision rules, door closure and isolating switch must have mechanical latching relation, that is to say and have only when door closure is in " closing " state that isolating switch could be operated, when door closure is " unlatching " state, isolating switch must be in halted state, and can't operate.In addition according to actual needs, many isolating switches are also needed to carry out separately safety interlocking, prevent under operation, test, halted state, to have the not operation personnel to be strayed into operation and cause security incident, the unit switch that uses both at home and abroad is to use lock of an isolating switch at present, complex structure, complex operation, very inconvenient, greatly reduce operating efficiency.
Summary of the invention
The purpose of this utility model is improved at above-mentioned shortcoming of the prior art, and a kind of multi-separation switch lock device easy to operate, simple in structure is provided.
The technical scheme that realizes the utility model above-mentioned purpose is: multi-separation switch lock device, has a body that has door closure and a fixed head, be provided with at least two isolating switches in the body, each isolating switch connects with the isolator operation handle by the rotating shaft of end, door closure is provided with a latch handle, fixed head is on the sidewall of body inner chamber, the below is installed the isolating-switch locking drive link that has Breech block respectively and is had the door locking drive link of Breech block down, on, following Breech block is respectively by helical gear and isolating-switch locking handle, door latch handle driving coupling, at isolator operation handle and isolating-switch locking drive link, in the rotating shaft of the isolating switch end between door locking drive link the locking dish is installed also, the outer indent of locking dish has some can making, the fore shaft that following Breech block embeds by rotation.
According to aforesaid multi-separation switch lock device, the isolating switch end also is provided with the fixed conveyor dish, between fixed conveyor dish and locking dish rotating shaft on movable drive plate is installed.
Further, described isolating-switch locking drive link, door locking drive link are installed on the fixed head by guide vane end stop by the two ends of fixed block and two drive links.
The utility model has the advantages that: when satisfying door closure and isolating switch mechanical latching, can also solve in many isolating switches any isolating switch and be in any operating state and all can obtain locking simultaneously, any isolating switch can't be operated.At any time, operate a handle and just can give any isolating-switch locking fast, thereby saved operating procedure, reduced the number of blocking mechanism, improved operating efficiency.

Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Multi-separation switch lock device, has a body that has door closure 16 and a fixed head 13, be provided with three isolating switches 4 in the body, each isolating switch 4 connects with isolator operation handle 1 by the rotating shaft of end, door closure 1 is provided with a latch handle 15, fixed head 13 is on the sidewall of body inner chamber, the below is installed the isolating-switch locking drive link 7 that has Breech block 9 respectively and is had the door locking drive link 8 of Breech block 14 down, on, following Breech block (9,14) helical gear 6 and isolating-switch locking handle 5 by connecting separately respectively, door latch handle 15 driving coupling, at isolator operation handle 1 and isolating-switch locking drive link 7, in the rotating shaft of isolating switch 4 ends that door locking drive link is 8 locking dish 10 is installed also, the outer indent of locking dish 10 has some can making, the fore shaft 17 that following Breech block (9,14) embeds by rotation.
Isolating switch 4 ends also are provided with fixed conveyor dish 3,10 on fixed conveyor dish 3 and locking dish rotating shaft on movable drive plate 2 is installed.
Isolating-switch locking drive link 7, door locking drive link 8 are installed on the fixed head 13 by guide vane end stop 12 by the two ends of fixed block 11 and two drive links.
For ease of understanding the operation principle of brief description present embodiment:
The corresponding locking dish of isolating switch, the fore shaft that a plurality of corresponding isolating switches service position is arranged on the locking dish, have only when the following Breech block on last Breech block on the isolating-switch locking drive link and the door locking drive link all breaks away from the fore shaft of locking dish by each self-corresponding handle, isolating switch could be operated, the disengaging of last Breech block (or embedding) action is to drive helical gear by the rotary isolation switch latch handle, drive the isolating-switch locking drive link then, drive again and go up the Breech block rotation.
In like manner, following Breech block is rotated by the revolving door latch handle.
When the unit switch door was closed, at first the revolving door latch handle made down Breech block break away from the fore shaft of locking dish, has locked the door closure of unit switch simultaneously this moment; Secondly the rotary isolation switch latch handle makes Breech block break away from the fore shaft of locking dish, at this moment could the disconnecting switch operation operating grip, drive the locking dish, drive activity drive plate then, then drive the fixed conveyor dish, drive isolating switch work again, at this moment the structural design of locking dish (a plurality of fore shaft) has determined always to have a fore shaft towards last Breech block, so as long as disconnecting switch operation latch handle, always can rotate in the fore shaft that embeds the locking dish, thereby realize arbitrary isolating switch carried out locking going up Breech block.
In addition, want to open explosion-proof unit switch door closure, must first rotary isolation switch latch handle make Breech block break away from the fore shaft of locking dish, with the isolator operation handle isolating switch is got to the state of quitting work again, at this moment can the rotary isolation switch latch handle make the Breech block rotation embed the fore shaft of locking dish, make isolating-switch locking, make the release of unit switch door closure simultaneously, just can open door closure this moment.
