Description

[Detailed explanation of the idea] This invention relates to an operation adjustment device for a cutter.

Some shear cutting devices have two shear cutting parts arranged horizontally or in a Y-shape. In a shear cutting device with such a configuration, a link mechanism is arranged between the operating part and the operated part so that both sheaths and shears are inserted at the same time, and this mechanism is adjusted. Adjustment of the mounting position of the cut portion is also carried out. Particularly, some of the former link mechanisms are equipped with an eccentric bearing, and the means for fixing this bearing is bolted. When the bolts are tightened in this manner, shocks and vibrations are rapidly applied to the bearings due to the reciprocating motion of the link mechanism, so it is necessary to firmly prevent the bolts from loosening. If the bolts are tightened with ordinary bolts, they will loosen, so special fixing means must be provided. For this reason, there is a drawback that adjustment cannot be easily performed.

The object of this invention is to eliminate the above-mentioned drawbacks and to provide an operation and adjustment device for a bean breaker that can extremely easily adjust the feeding operation of a bean breaker.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing the operation and adjustment device for the vacuum shear disconnector when the vacuum sheath disconnector is placed horizontally, and 1 is a supporting insulator. An insulated operating rod 2, which is an operating section, is inserted into the support insulator tube 1, and protrudes from the support insulator tube 1 via a bearing 3 fixed to the upper part of the support insulator tube 1. Reference numeral 4 denotes a case fixed to the upper part of the support insulator 1, and this case 4 has flanges 4a and 4b on the left and right sides.
The insulator pipes 5a and 5b are connected. Vacuum sheath disconnectors 6a, 6b, which are operated parts, are housed in the sheath insulators 5a, 5b, and movable lead rods 7a, 7b of the vacuum sheath disconnectors 6a, 6b are connected to guide bearing portions 8a. , 8b. 7
c and 7d are pressure springs. Note that the guide bearing part 8
a, 8b are fixed to the insulator tubes 5a, 5b.

One end of the movable lead rods 7a, 7b is connected to the link mechanism 9 using pins 9a, 9b, and the other end is provided with movable electrodes 10a, 10b. 9c,
9d is a roller. 11a and 11b are fixed electrodes. The upper end of the insulated operating rod 2 has a second
A bearing 12 shown in FIGS. and 4 is fixed. This bearing 12 has a groove 13, which is a locking portion, formed on its inner peripheral surface. As shown in FIG.
5 is inserted so that it can be inserted and removed like a spline shaft. A pin 16 is provided protruding from the eccentric shaft 15, and the link mechanism 9 is attached to this pin 16.

Next, the operation of the above embodiment will be described. When the movable electrode 10a of the vacuum shield breaker 6a on the right side shown in FIG.
Then, rotate the eccentric shaft 15 clockwise and insert it into the bearing 12 again. Then, the pin 16 of the eccentric shaft 15 moves to the right, and by attaching the link mechanism 9 to the pin 16, the movable electrode 10a is brought into contact with the fixed electrode 11a. In this way, the closing operation of the shiso breaker can be easily adjusted.

Figure 5 shows a case where a gap α occurs between the movable electrode 10b and the fixed electrode 11b on the side of the vacuum shield and disconnector 6b (left side in the figure), and in this Figure 5, the direction is opposite to that in Figure 1. The eccentric shaft 15 is rotated. That is, counterclockwise.

FIGS. 6 and 7 show other embodiments of the engaging means of this invention, and FIG. 6 shows an example in which an inpolyute serration engaging means is used for the bearing 12 and the eccentric shaft 15. Figure 7 shows the bearing 12 and eccentric shaft 1.
A recessed groove 17 is bored in the key 1 of the recessed groove 17.
8 is used to constitute the engagement means. In the engagement means shown in FIG. 7, the eccentric shaft 15 can be connected to the eccentric shaft 15 without pulling out the eccentric shaft 15 by removing the key 18.
Adjustments can be made by rotating.

As described above, according to this invention, a bearing having a locking part on its inner periphery and an eccentric shaft having an engaging part engaged with the locking part on its outer periphery are provided, so that the structure is extremely simple. The closing operation of the disconnector can be easily synchronized, and since the operation is adjusted using a bearing and an eccentric shaft, adjustment is easy and mechanically stable.
