JPH03157176A - Peeling device for tank wall surface - Google Patents

Abstract

PURPOSE:To allow the efficient conduct of a peeling work by providing a truck on a post, providing a swiveling truck via wheels on the side face of the truck and providing a high pressure water injecting nozzle on the swiveling truck. CONSTITUTION:The swiveling truck 5 rotates horizontally along the outer periphery of the circular lifting truck 9 and peels the coating material or external material of the side wall surface 1 of a tank when the high pressure water is injected from the nozzle 8 and a motor 17 is driven. The lifting truck 9 is properly moved upward when the nozzle 8 makes one turn. The high pressure water is then injected again from the nozzle 8 and the swiveling truck 5 is swiveled opposite from the previous time to peel the wall surface of the tank. The lifting truck 9 is properly moved upward again when the nozzle turns one round around the side face of the tank. The high pressure water is injected from the nozzle and the swiveling truck 5 is swiveled reversely to make the similar work. The working efficiency is improved in this way.

Description

Detailed Description of the Invention <Industrial Application Field> The present invention uses high-pressure The present invention relates to a tank wall stripping device for stripping using water.

<Conventional technology> Conventionally, peeling of the coating material and paint inside the tank was scraped off with a sharp tool. There were problems in that the efficiency of the bridging work was poor and the work itself was difficult to construct.

<Problem to be solved by the invention> It is an object of the invention to provide a device that can carry out stripping work efficiently and without the need for workers to enter the work environment under adverse conditions. .

Means for Solving the Problems> A support is provided in the center of the tank, a rotary lifting platform that can be raised and lowered and rotated is provided on the support, and a high-pressure water injection nozzle is fixed to the rotating lifting stand so that the side wall surface of the tank is fixed. It is constructed so that it can be peeled off by spraying high-pressure water onto it.

<Embodiment> A column 12 is fixedly installed in the tank to be peeled, extending between the bottom surface of the tank and the top plate, and a plurality of arms 2.2 and 3. with telescopic adjusters are attached from the column 12 to the side wall of the tank. 3
Extend and fix. The column 12 is provided with a cart 9 that is suspended by a drive source 20 and is movable up and down.
A gear 19 whose central axis is the center of the support column 12 is fixedly installed on the upper part of the zero-crossed carriage 23 which is restrained through the support column 12.

On the other hand, a rotating truck 5 is provided on the outer flange of the truck 9, with wheels 14 on the upper side, three wheels 15 on the lower side, and wheels 13 on the side. wheels z2 are provided, and a nozzle mounting base 7 that can move forward and backward is provided on a bracket 6 provided on the rotating cart 5, and a nozzle 8 is fixedly installed. Further, the rotating truck 5 is provided with a motor 17 with a speed reducer, and a gear 18 is fixedly installed on the output shaft of the motor 17, and is meshed with a gear I9 provided on the truck 9. The above is the configuration of the present invention.

<Operation> When high-pressure water is injected from the nozzle 8 and the motor 17 is driven, the rotating truck 5 rotates horizontally along the outer periphery of the circular truck 9, and the coating material or lining material on the side wall of the tank is peeled off. When the nozzle rotates once, the elevating cart 9 is appropriately moved upward, high-pressure water is injected from the nozzle, and the rotating cart 5 is rotated in the opposite direction to the previous time to peel off the tank wall surface.

When the nozzle has made one round around the side of the tank, the elevating cart 9 is moved upward again, high-pressure water is injected from the nozzle, and the rotating cart 5 is rotated in the opposite direction to perform the same operation. The above operations are repeated in sequence to remove unnecessary materials from the side wall of the tank. With the above-mentioned action, this device can perform the work without the operator entering the tank, so the work can be done smoothly even in poor working environments, and the efficiency is greatly improved compared to when peeling is done with tools.

<Effects of the Invention> Since the worker can work without entering the tank, there is no problem even in a bad working environment, and the work efficiency is improved compared to the conventional method, so the effect is great.
