The locking device locking of the starter of the present embodiment, the course of work of unblanking and each parts relation of cooperatively interacting are summarized as follows:
See Fig. 1 and Fig. 5, when starter, when closing the door operating state, the driving cog 92 of the second locking bar 9 meshes with the gear of quick operating valve locking device 4 46; The quick operating valve deadlock lever 64 of the first linkage 6 is inserted in the lockhole 93 of the second locking bar 9, and the left end of the second locking bar 9 is tight against the right side of lower contact site 82-3 of the pin 82 of the second linkage 8; The upper stop part 82-2 of the pin 82 of the second linkage 8 and 63 dislocation of the central door locking quick operating valve pin of the first linkage 6; The ratch 61 of the first linkage 6 meshes with the first gear 73 of driven gear device 7; The second gear 74 of driven gear device 7 is meshed with the driving cog 52 on the left side body of rod of the first locking bar 5; The power supply locking bar 37 of power locking device 3 is inserted in the first lockhole 54 of the first locking bar 5; The reversion locking bar 27-2 that the forward locking bar 27-1 of the isolating switch locking bar 27 of separation switch lock device 2 is inserted in the second lockhole 55 of the first locking bar 5 the isolating switch locking bar 27 of (when the motor of being controlled by starter under the forward state) or separation switch lock device 2 is inserted in the 3rd lockhole 56 of the first locking bar 5 (when the motor of being controlled by starter under inverted status); Driving cog 52 on the right side body of rod of the gear 16 of central door locking device 1 and the first locking bar 5 is meshed; Now, the door of starter can not be opened, in the operating state of closing the door.
See Fig. 1 and Fig. 4, when starter need to open the door, at first need to press the latch buttons 29 of separation switch lock device 2, make the locking wheel 28 of separation switch lock device 2 break away from clamping with latch buttons 29, then rotate the second handle 21 of separation switch lock device 2 to the draw-in groove of stop position, make isolating switch locking bar 27 pull out release in the second lockhole 55 of the first locking bar 5 or the 3rd lockhole 56; The 3rd handle 31 that then rotates power locking device 3 is by on-position to de-energized, and the power supply locking bar 37 that drives power locking device 3 is pulled out release in the first lockhole 54 of the first locking bar 5; Then the first handle 11 of rotation center locking device 1 is from the position of closing the door to opening position, in this process, the gear 16 of central door locking device 1 pulls the first locking bar 5 to move from left to right, simultaneously, the first locking bar 5 is by the transmission of the first gear 73 of driven gear device 7, the second gear 74 that drives coaxial driven gear device 7 rotates, thereby drive the first linkage 6, moves upward; Make the quick operating valve deadlock lever 64 of the first linkage 6 from the interior disengaging release of the lockhole 93 of the second locking bar 9; Finally rotate the 4th handle 41 of quick operating valve locking device 4 by closing the door to opening position, in this process, the gear 46 of quick operating valve locking device 4 takes drive the second locking bar 9 to and moves from left to right; The right side of the lower contact site 82-3 of the pin 82 of the left end of the second locking bar 9 and the second linkage 8 disengages; Under the effect of the second linkage 8 elastic acting force of compressed spring 84 under its state of closing the door, the upper stop part 82-2 of the pin 82 of the second linkage 8, to left movement, connects with the central door locking quick operating valve pin 63 of the first linkage 6; Now can realize that starter opens the door.
The course of work that starter is closed the door is contrary with the aforesaid course of work of opening the door, and according to the operation of the reverse order with opening the door, can realize closing the door of starter.
To sum up, the locking device of the mine explosion-suppression and intrinsic safety type multi-circuit vacuum electromagnetic starter of the present embodiment, simple in structure, cost is lower; By the design of mechanical structure, the operation that realization must be opened the door and close the door according to the order of setting, otherwise can't realize opening the door or closing the door, thereby fundamentally stopped starter is carried out the operation of hotline maintenance, make fail safe be greatly enhanced.And, be provided with externally threaded cylindrical cascade double-screw bolt 51 by the two ends at the first locking bar 5, when starter need to carry out cascade, can realize easily cascade by supporting cascade jockey.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not in the situation that break away from spirit and scope of the present utility model; can also make various conversion and variation and obtain the corresponding technical scheme be equal to, therefore all technical schemes that are equal to all should be included into scope of patent protection of the present utility model.
