Description

[Detailed Description of the Invention] The present invention limits the peak value of shock overvoltage caused by lightning and circuit opening/closing by shunting the accompanying current, protects the insulation of electrical facilities, and The present invention relates to an electrode forming device for an arrester block used as a component of an arrester (surge arrester), which has the function of interrupting a follow-on current in a short time and restoring itself to the current state without disturbing the normal state of the system. relates to an electrode forming device that automates the formation of electrodes on both sides of an arrester block.

Figures 1 and 1B are a plan view and a side view of this type of arrester block. Conventionally, when electrodes are formed on both sides of the arrester block, short cylindrical arrester block pieces ( Electrode (1, A) is formed by manually spraying molten aluminum onto both end faces of electrode (1, A).
(IA) is not only extremely inefficient, but also the spraying of molten aluminum is unhygienic as fine aluminum powder is scattered during the work.

This invention was made with attention to this point, and it aims to automate the formation of electrodes on both sides of the arrester block, and also prevents fine aluminum powder from scattering during the spraying operation of molten aluminum to form the electrodes, thereby improving hygiene. An object of the present invention is to provide an electrode forming device for an arrester block that creates a comfortable working environment.

That is, FIG. 2 and FIG. 6 are both a front view and a side view showing one embodiment of the present invention. ) A plurality of arrester block pieces before electrode formation are housed in a magazine (4) placed in the magazine (4), (5) is inserted into the slit (3a) of the magazine case (3) and the A substantially C-shaped lifting hanger (8) for removably hanging the case hangs the lifting hanger (5) and has a rotatable reversing shaft (9) for reversing the hanging hanger (5). The movable trolley (8) is moved on the conveyor rail (6) via rollers (7), and the reversing axis (
9) The upper end is removably engaged with the drive hook (G) of the actuator α→ for driving the reversal shaft, which is installed at a predetermined position in the upper part of the spraying chamber (C) where molten aluminum is sprayed. A driven hook (10) is attached.

(11a) to (11d) are a plurality of conveyance sprocket wheels on which a driving chain (12a) connected at both ends is wound around the moving cart (8), and among these, the sprocket wheel (11d) is connected to the conveyance motor 02. is directly connected to the drive shaft of the mobile cart (8) via the drive chain (12a).
) in a predetermined direction. The α force is a protection stand arranged at the bottom of the conveyance path of the magazine case (3) that has been conveyed from above the moving table (A) by the lifting hanger (5). A movable table on which magazine cases (3) are placed at predetermined intervals. The feed screw shaft 01) screwed into the nut (A) fixed to the bottom of the table feed motor (A)
The movable table slope is moved by rotating it in a predetermined direction.

Next, (c) is a pipe that feeds a predetermined amount of molten aluminum produced by the molten aluminum generator (c) to the spray gun OQ in the spray chamber, and (c) is a pipe that supports the spray gun a→. It is a support arm.

Since the arrester block electrode forming device of the present invention is constructed as described above, the magazine case (3) containing a large number of arrester block pieces (1) is arranged at predetermined intervals on the moving table (a). Also, when the start switch (not shown) of the device is turned ON, the moving table is moved by the table feed motor plow (screw shaft 01).
It moves a predetermined distance by rotating the hoisting hanger (5
) are attached to the magazine case (3)) (3a
) (3a) automatically stops at the position shown in Fig. 4 (A), (B), and (I) in Fig. 2), then the transport motor (2) stops automatically. When the movable cart (8) enters the spray chamber and the magazine case (3) suspended by the lifting hanger (5) approaches the spray gun <10, the spray gun (1→ Molten aluminum begins to be sprayed onto one side of the arrester block piece (1) in the magazine case (3), and the spraying of molten aluminum continues while the arrester block piece (1) moves [5th Figures (A), (B), and the position indicated by (If) in Figure 2].

Then, when the spraying of a predetermined amount of molten aluminum is completed, the driven hook 00 of the movable cart (8) is secured to the drive hook ←→ of the actuator a4, and the drive hook υ
Since the driven hook 00 is rotated by 180 degrees [positions shown in Fig. 6 (A), (B) and (G) in Fig. 2], the driven hook ◇0 and the reversing shaft (9) are rotated by 180°. The integrated lifting hanger (5) holds the magazine case (3) up to 18
At the same time as the conveyor motor 09 is rotated by 0 degrees, the transport motor 09 is rotated in the opposite direction, so that the movable cart (8) again begins to move in the direction of the spray gun 0 [as shown in FIGS. 7(A) and 7(B). situation〕.

Then, when the magazine case (3) comes close to the spray gun αQ again, molten aluminum starts to be sprayed from this spray gun 0Q to the opposite surface of the arrester block piece (]) inside the magazine case (3), and this arrester The spraying operation of molten aluminum continues while the block piece (1) is moved.

When the prescribed amount of molten aluminum has been sprayed, the magazine case (3), which had been lifted from the lifting hanger (5) of the movable cart (8), is moved to the movable table (A).
When the moving table (A) is moved a predetermined distance by the rotation of the feed screw shaft (C) by the table feed motor, both claws of the lifting hanger (5) will be exposed to the molten aluminum. Magazine case (3) containing arrester plotter piece (1) after electrode formation by
It is removed from the slit (3a) of the magazine case (3) and inserted into the slit (3a) of the adjacent magazine case (3) containing the arrester block piece with no electrodes formed thereon, and then lifted up, as described above. Arrester block piece (1
) starts the process of automatic electrode formation.

As described above, according to the arrester block electrode forming apparatus of the present invention, the arrester block can be formed by simply setting the magazine case (3) containing a plurality of arrester block pieces (1) on the movable table (a). Not only can electrodes be automatically formed on both sides of piece (1),
Since the spraying work of molten aluminum on both sides of the unstablock piece (1) is carried out in the spraying chamber (c), scattering of aluminum fine powder is prevented and a sanitary work environment can be created. It is effective.
