The assembling procedure of the operating device in the above-described configuration of this embodiment will be described with reference to Figs. 17 to 19. Fig.

17, for example, the first operation lever 6 and the second operation lever 7, which have the same structure, are arranged so that the shaft tube portion 6A and the shaft tube portion 7A are opposed to each other, In this state, as shown in Fig. 17, the second operation lever 7 is reversed with respect to the first operation lever 6.

Next, the second operation lever 7 is moved toward the first operation lever 6 to move the convex portion 6g of the first operation lever 6 and the concave portion 7f of the second operation lever 7, In the direction of the arrow in Fig. At this time, the holes 7a of the shaft portions 7A of the second operating lever 7 are aligned with the holes 6a of the shaft portions 6A of the first operating lever 6, The shaft receiving portion 7A of the first operating lever 6 is engaged with the shaft receiving portion 6A of the first operating lever 6. [ 18, the shaft shank 6A of the first operating lever 6 and the holes 6a, 7a of the shaft sleeve 7A of the second operating lever 7 are provided with supporting shafts 8 ). The first operation lever 6 and the second operation lever 7 can be connected to the support shaft 8 so as to be rotatable around the support shaft 8. [

18, the shaft supporting portions 9 are provided on both ends of the support shaft 8 and are disposed in the box body 2 of the opening and closing device 1. Thereafter, The first operation lever 6 and the second operation lever 7 are fixed to the box body 2 by the bolts 10 from the outside of the box body 2 as shown in Fig. 2).

Next, the operation of the operating device in the above-described configuration of this embodiment will be described.

1, the lever portion 6C of the first operation lever 6 provided in the box body 2 is connected to the operating rod 4A of the main circuit switch 4 by the pin shaft 11, Respectively. The lever portion 7C of the second operating lever 7 is connected to the operating rod 5A of the earthing switch 5 by the pin shaft 12, respectively. Thereby, the first operation lever 6 of each phase and the second operation lever 7 of each phase interlock with each other in accordance with the operation of the operation device, and the main circuit switch 4 and the ground switch 5 Can be opened and closed in a batch manner.

20 shows a case where both the main circuit switch 4 and the ground switch 5 of each phase are in an open state. In this state, the angle formed by the lever portion 6C of the first operation lever 6 and the lever portion 7C of the second operation lever 7 is approximately 180 degrees, as shown in Fig. The protrusion 16i of the rotation stopping member 16E of the first operation lever 6 is positioned with a gap around the outer periphery of the shaft sleeve 7A of the second operation lever 7. [ Likewise, the projection 17i of the rotation stopping member 17E of the second operation lever 7 is provided with a clearance around the outer periphery of the shaft sleeve 6A of the first operation lever 6.

Fig. 21 shows a case where the main-circuit switch 4 of each phase is in the closed state and the ground switch 5 is in the open state. In this state, the angle formed by the lever portion 6C of the first operation lever 6 and the lever portion 7C of the second operation lever 7 becomes 180 degrees or more. It is necessary to push down the lever portion 6C of the first operating lever 6 and the operating rod 4A to connect the movable contact and the fixed contact of the main circuit switch 4 to each other. That is, this angle is determined in accordance with the gap between the movable contact and the fixed contact constituting the main circuit switch 4, and specifically, the angle is realized by the following configuration.

21, when the lever portion 6c of the first operation lever 6 is rotated in the counterclockwise direction, the tip end of the projection portion 16i of the rotation stopping member 16E of the first operation lever 6 , And abuts against the outer periphery of the shaft sleeve 7A of the second operating lever 7. [ As a result, the rotation stopping member 16E prevents the rotation of the second operation lever 7, which drives the earthing switch 5, in the clockwise direction. Similarly, the tip end of the projection 17i of the rotation-stopping member 17E of the second operation lever 7 is in contact with the outer periphery of the shaft sleeve 6A of the first operation lever 6, 5 in the clockwise direction of the second operation lever 7 for driving the second operation lever 7. As a result, the closing operation of the earthing switch 5 is locked from this state.

The tip end of the protruding portion 16i of the turn blocking member 16E of the first operation lever 6 is connected to the tip end of the protruding portion 16i of the first operation lever 6 in the state in which the main circuit switch 4 of each phase is in the open state and the earthing switch 5 is in the closed state, And abuts against the outer periphery of the shaft sleeve 7A of the second operation lever 7. [ As a result, the rotation stopping member 16E prevents the rotation of the first operation lever 6 for driving the main circuit switchgear 4. Likewise, the tip end of the projection 17i of the rotation stopping member 17E of the second operation lever 7 is in contact with the outer circumference of the shaft tube portion 6A of the first operation lever 6, Thereby preventing rotation of the first operating lever 6 that drives the first operating lever 4 in the counterclockwise direction. As a result, in this state, the closing operation of the main circuit switch 4 is locked.

The relationship between the length of the projection 16i of the rotation stopping member 16E and the rotation angle of the first operation lever 6 will now be described in detail with reference to Fig.

In Fig. 22, 1 is the length of the lever portion 6C, and indicates the length between the center of the connecting hole 6B and the hole 6a. is a rotation angle of the first operation lever 6 when the tip of the protrusion 16i comes into contact with the outer circumference of the shaft sleeve 7A of the second operation lever 7, (Vertical line). x is the vertical movement distance of the first operation lever 6 and indicates the length corresponding to the gap between the movable contact and the fixed contact constituting the switch 4. [

In the operation of the rotation blocking member shown in Fig. 22, the rotation blocking member is formed by the rotation angle [theta] and the vertical movement distance x of the first operation lever 6 in accordance with the following relational expression.

x = l x tan?

That is, x is determined by the gap between the movable contact and the fixed contact of the switch 4 in use and the rotation angle? Is calculated from the length 1 of the lever portion 6C of the first operation lever 6, Is determined. The tip end of the projection 16i of the rotation stopping member 16E is positioned outside the shaft sleeve 7A of the second operation lever 7 when the first operation lever 6 is rotated by this rotation angle [ It may be formed so as to be in contact with the periphery. 22 shows only the rotation-stopping member 16E of the first operation lever 6, but the rotation-stopping member 17E of the second operation lever 7 is also formed in the same relationship.

It is necessary to change the rotation angles of the lever portions 6C and 7C of the operation levers 6 and 7 along the gap between the movable contact and the fixed contact constituting each of the switches 4 and 5 as described above, According to the present embodiment, the rotation angle of the lever portions 6C and 7C can be easily changed by adjusting the lengths of the protruding portions 16i and 17i in the respective rotation blocking members 16E and 17E.

According to one embodiment of the operating device of the present invention, the first operating lever 6 for collectively operating the movable contacts of the three-phase main circuit switch 4, and the first operating lever 6 for operating the movable contacts of the earthing switch 5 The proximal end portions of the operation levers 6 and 7 are rotatably supported on one common support shaft 8 and the other end portion of the operation lever 6 is supported on one of the operation levers 6, Since the rotation stopping members 16E and 17E for blocking the rotation of the other operation lever are provided, the configuration of the lock mechanism for the lock of the switch can be simplified. As a result, it is possible to provide an operation device for a switch that reduces the number of components.

Since the rotation angle of the lever portions 6C and 7C can be easily changed by adjusting the lengths of the tongue-like projections 16i and 17i in the respective rotation-blocking members 16E and 17E, The branch can correspond to the switch. As a result, it is possible to provide an operation device of an opening / closing machine in which manufacturing costs and the number of parts are reduced.

Further, since the first operation lever 6 and the second operation lever 7 have the same structure and can be manufactured in the same mold, the manufacturing cost and the number of parts can be reduced.
