Description

[Detailed description of the invention] <Industrial application field> This invention is placed over a processing liquid tank and is used for maintenance work such as replacing the electrode plate of the surface treatment device, repairing the suction duct, and repairing the stirring device. This invention relates to a maintenance workbench used as a scaffolding.

<Prior art> In this type of surface treatment apparatus, when replacing the electrode plate, repairing the suction duct, repairing the stirring device, etc., as shown in FIG. Passing materials a, a before and after the power feeding parts 3, 3 on the mounting flanges 2, 2 formed along the sides, placing the base plate b on the spanning materials a, a, and placing the power feeding parts 3, 3
A maintenance workbench c was constructed that straddles the area, and the above-mentioned maintenance work was performed using this workbench c as a scaffold.

<Problems to be solved by the invention> In such a conventional configuration, it is necessary to transport the base plate b to the required position and perform the above-mentioned assembly work, which is troublesome, imposes a large work burden, and Ta.

The object of the present invention is to provide a maintenance workbench that does not have the above-mentioned drawbacks.

<Means for Solving the Problems> The present invention provides a base plate that is attached to both ends of the base plate, which is hung over mounting flanges formed along both sides of the processing liquid tank row, and that moves along the processing liquid tank row. The carrier is provided with a removable hook that is latched to a hanger latching portion formed on the elevating body of the carrier, and a foot portion on the back side of the hook that straddles the power feeding portion that is attached to the mounting flange at the front and rear. It is something.

<Function> The maintenance workbench is suspended by hooking its hook to the hanger locking portion of the elevating body of the carrier, and is transported in this state to above the required processing liquid tank by the carrier. Then, by lowering the elevating body, it is placed on the mounting flange. At this time, since the foot portion is formed on the lower surface of the base plate, it becomes possible to straddle the power supply section and ride on the base plate.

<Example> An example of the present invention will be described with reference to the accompanying drawings.

As shown in FIG. 3, a rail 5 provided along the processing liquid tank row 1 is provided with a rail 5 that is self-propelled by a drive device and is controlled to move between required liquid tanks. Carrier 6 is on the shelf. The carrier 6 is provided with an elevating body 9 having mountain-shaped hanger locking portions 8, 8.
The hooks 13, 1 of the hanger 10 shown in FIG.
3 is locked from below. This hanger 10 is
Connecting rods 14, 14 having hooks 13, 13 at the upper ends are erected at both ends of the power feeding bar 11, and the lower portions of the connecting rods 14, 14 serve as power receiving seats 12, 12, and the hooks 13, 13 is in the shape of a cap whose lower surface serves as a locking surface. In addition, the power supply bar 1
1 is hung with hanging pieces 15, 15 to suspend the object to be processed.

The carrier 6 transports the hanger 10 to a predetermined processing liquid tank by its movement, and as the elevating body 9 descends, the power receiving seats 12, 12 of the hanger 10 are arranged near the processing liquid tank row 1. mounting flange 2,
The object to be processed is placed on a power supply section 3 provided at 2, and the object to be processed is immersed in the processing liquid tank. The object to be treated receives power from the power supply parts 3, 3 via the power receiving bases 12, 12, and the power supply bar 11, and undergoes electrolytic treatment such as plating in the treatment liquid tank.

Next, the maintenance stand 20 related to the main part of the present invention is installed in the first and second positions.
The diagram will be explained.

The base plate 21 of the maintenance stand 20 has U-shaped frames 2 on both sides.
Assembly plates 23, 23 are arranged and fixed on the upper and lower sides of 2, 22, and fitting grooves 24, 24 are formed in the center of both ends, and a cap-shaped hook 2 is inserted into the fitting grooves 24, 24.
Connecting rods 27 and 27 having 6 and 26 at the upper ends are fitted and erected. The connecting rods 27, 27 are removably held by bolts 29 inserted through holes in reinforcing members 28 provided on both sides of the fitting grooves 24, 24.

The hooks 26, 26 are formed in substantially the same shape and at the same spacing as the hooks 13, 13 of the hanger 10, and can be hooked to the hanger locking portions 8, 8 of the elevating body 9 of the carrier 6 from above. .

Further, on both sides of the back surface of the base plate 21, legs 30, 30 having a U-shaped cross section are provided extending in the width direction. The height of the foot parts 30, 30 is the same as that of the power feeding part 3,
The height shall exceed 3.

In the above configuration, as shown in FIGS. 1 and 3,
Hooks 26 are attached to the hanger locking portions 8, 8 of the elevating body 9,
26 to raise the elevating body 9, the carrier 6 is made to run along the rail 5 and stopped above a desired processing liquid tank. Next, hanger locking parts 8, 8
As shown in FIG.
Place 0,30.

Therefore, it becomes possible to perform various maintenance operations using the base plate 21 as a scaffold. At this time, the connecting rod 27,
If the connecting rod 27 interferes with the work, operate the bolt 29 and remove the connecting rod 27 from the fitting groove 24, 24.
27 is removed.

<Effects of the invention> As clarified by the above explanation, the invention enables the carrier 6 to be used to transport the maintenance platform 20 and to perform the work of mounting it on the mounting flanges 2, 2. Therefore, it is easy to transport and install, and there is no need for assembly work, which has excellent effects such as reducing the burden on the operator.
