Abstract
The utility model provides a mechanical-electric interlocking device for an operating mechanism, comprising a frame, a transmission shaft extending out of one end of the frame, a manual operating handle corresponding to and being matched with the transmission shaft, an interlocking plate and a microswitch, wherein the interlocking plate is movably mounted at the outer side of the frame and adjacent to the transmission shaft, and the microswitch is arranged below the interlocking plate and matched with the interlocking plate; a circular arc which can be matched with the transmission shaft is arranged at the end part of the interlocking plate; and the lower edge of the interlocking plate is provided with a pair of tooth slots which can be matched with the microswitch and can be positioned. On one hand, during electric operation, the interlocking plate is matched with the transmission shaft through the circular arc so that the manual operating handle can not be matched with the transmission shaft to use, therefore, manual operation is prevented; on the other hand, during the manual operation, the interlocking plate and the transmission shaft are separated mutually to enable the microswitch to make switching, at the time, the manual operating handle can be used by being matched with the transmission shaft, and the electric operation can not be carried out due to the switching of the microswitch.
Description
Technical field
The utility model relates to a kind of operating mechanism, particularly a kind of mechanical electric interlock that is used for operating mechanism.
Background technology
The power switch industry requires earthed switch or isolating switch on the GIS equipment, and manual operation on the spot also can be on the spot or distant place electric operating.Yet, in order to guarantee safety, when manual operation, even misoperation does not allow electric operation yet; On the contrary, when electric operating, do not allow manual operation yet.
Realize that this interlocking ratio is easier on electric, but the electric elements relative failure frequency is higher, in case and electric elements break down and can not visual sense, and fail safe is not high enough.Therefore, need a kind of mechanical device simple in structure, that reliability is high to realize this interlocking.
In view of above problem, be necessary to provide a kind of mechanical electric interlock that is used for operating mechanism that can solve above technical problem in fact.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, reliability and the safe mechanical electric interlock that is used for operating mechanism.
For achieving the above object, the utility model provides a kind of mechanical electric interlock that is used for operating mechanism, comprise framework, extend the power transmission shaft of framework one end, and the manual operation handle that cooperate corresponding with this power transmission shaft, movably be installed in the framework outside and with the interlock plate of the adjacent setting of power transmission shaft, and the sensitive switch that places the interlock plate below and cooperate with interlock plate, described interlock plate end is provided with the circular arc with the power transmission shaft coupling, and the interlock plate lower edge is provided with a pair of teeth groove that cooperates and locate with sensitive switch.
As preferred embodiment of the present utility model, the circular arc that is provided with on the described interlock plate is 1/2nd circular arcs;
As preferred embodiment of the present utility model, described interlock plate central authorities are provided with the elongated slot that runs through its thickness, and the pin that is provided with in this elongated slot and the framework cooperates;
As preferred embodiment of the present utility model, described teeth groove is a vee gutter;
As preferred embodiment of the present utility model, what cooperate with the teeth groove of interlock plate on the described sensitive switch has a lug, nib.
The mechanical electric interlock that the utility model is used for operating mechanism has the following advantages at least: the utility model interlock plate is provided with the circular arc that mates with power transmission shaft at an end adjacent with power transmission shaft, so, during electric operating, interlock plate is by circular arc and power transmission shaft coupling, like this, the manual operation handle just can not be used with power transmission shaft, prevents manual operation; On the contrary, during manual operation, interlock plate and power transmission shaft are separated from one another, and by the sensitive switch location, at this moment, the manual operation handle can be used with power transmission shaft, and electric operating is owing to the location of sensitive switch can not be carried out.

Embodiment
Below in conjunction with accompanying drawing the mechanical electric interlock that the utility model is used for operating mechanism is described in detail:
See also shown in Figure 1, the mechanical electric interlock that the utility model is used for operating mechanism comprises framework, extends the power transmission shaft 1 of framework one end, and manual operation handle 3 of cooperating corresponding with this power transmission shaft 1, movably be installed in the framework outer wall side and with the interlock plate 5 of power transmission shaft 1 adjacent setting, and the sensitive switch 7 that places interlock plate 5 belows and cooperate with interlock plate 5.
Please consult shown in Figure 2ly especially, described junction panel 5 is a platy structure, and in its end, just adjacent with power transmission shaft 1 end is provided with 1/2nd circular arc 51, and this circular arc 51 runs through the thickness of interlock plate 5, and this circular arc 51 just in time is complementary with power transmission shaft 1; The central authorities of described interlock plate 5 are provided with the elongated slot 53 of impenetrating thickness, and the pin that is provided with in the housing extends in this elongated slot 53; In addition, the lower limb of interlock plate 5 is provided with the teeth groove 55 of two adjacent settings, and this teeth groove 55 is a vee gutter, mates and the location in order to the sensitive switch 7 with this interlock plate 5 belows setting.
Described sensitive switch 7, its neighboring is provided with lug, nib 71, this lug, nib 71 just in time is placed in the teeth groove 55 of interlock plate 5 belows, and along with moving of interlock plate 5, described lug, nib 71 moves to another teeth groove 55 that is adjacent from its initial teeth groove 55.
During use,, then interlock plate 5 is moved towards the direction away from manual operation handle 3 if under manual state, operate, interlock plate 5 and power transmission shaft 1 are separated from each other, and sensitive switch 7 is switched, at this moment, manual operation handle 3 can be used with power transmission shaft 1, specifically as shown in Figure 3; In contrast, if will then interlock plate 5 be moved in the opposite direction in manual operation, itself and power transmission shaft 1 are mated, specifically as shown in Figure 2, at this moment, operating personnel can not cause that accident takes place because of misoperation.
The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
