Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for removing deposits on storage tank walls, etc.

[Prior art and its problems]

In storage tanks such as storage yards and shipboard hatches,
Powdered materials such as iron ore and coal are stored, but after these powdered materials are discharged, deposits on the walls are removed.

Conventionally, this deposit was removed manually from below using a bamboo spatula 5 to 6 meters long, but this required a considerable amount of effort and was extremely difficult to work in high places. .

Therefore, as shown in Japanese Utility Model Application Publication No. 60-10039, there is a construction machine that uses a construction machine and has a scraping tool replaceably attached to the tip of its boom. This device uses a scraping tool that is changed each time depending on the condition of the wall surface and the amount of deposits.
For example, a plate-shaped tool is used for deposits on the smooth surface of an inboard hatch, and a bar-shaped tool is used for deposits between reinforcing ribs. Therefore, it is necessary to temporarily stop the work every time it is replaced, which is troublesome and reduces work efficiency. In addition, depending on the location, the scraping tool may damage the wall surface, so the boom must be operated carefully.In particular, the walls of the ship's hatch have many irregularities due to curved surfaces and reinforcing ribs, so work efficiency is affected. It will drop.

On the other hand, as shown in Japanese Utility Model Application Laid-open No. 60-73749, there is also a device that includes a nozzle at the tip of a boom that can freely rotate and extend, and removes deposits by spraying high-pressure water from the nozzle. In this case, if a large amount of deposits is firmly attached, high-pressure water must be continuously sprayed onto the same location in order to completely remove it. Therefore, it is necessary to have a large-capacity water tank to secure a large amount of water, or to frequently replenish water. In this case, if the water tank is provided on a separate cart, mobility will be poor, and if it is configured as an integrated device with a large capacity water tank, it is dangerous because there is a risk of overturning. Moreover, the provision of such a large capacity water tank increases the size of the entire apparatus, making it difficult to work in narrow ship hatches and the like.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
It is an object of the present invention to provide a deposit removing device that has good working efficiency and can be operated safely, and the entire device can be formed compactly.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a deposit removal device in which a scraping plate is provided at the tip of a bendable and undulating arm provided on a revolving body on a traveling means, and a compressed fluid jetting nozzle is installed in parallel on the scraping plate. The gist is that the nozzle is connected to the counterweight water tank on the revolving body.

[Effect]

According to the present invention, a scraping board is mainly used to remove deposits on smooth wall surfaces, and high-pressure water is jetted to remove deposits between reinforcing ribs that cannot be removed by the scraping board. , you can easily use them without interrupting your work. At this time, the water tank acts as a counterweight and maintains the stability of the device.

Furthermore, if water is ejected from the compressed fluid ejecting nozzle at the same time as the scraping plate is being worked, no dust will be generated.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the deposit removal apparatus of the present invention, and in the figure, 1 indicates a revolving body on a traveling means 10 such as a cover belt. The revolving body 1 is equipped with necessary equipment such as a driver's seat 9 and a hydraulic motor 7, and an arm 11 that is bendable and movable is attached to the revolving body 1. The arm 11 consists of a first arm 2 whose lower end is pivotally supported on the rotating body 1 and a second arm 3 whose lower end is pivotally supported on the upper end of this first arm 2. A cylinder 21 for raising and lowering is attached to the arm, and a cylinder 31 for bending is attached between the second arm 3 and the first arm 2. Note that this second arm 3
may have a multi-stage structure and expand and contract itself.

A joint portion 4 having a box structure is attached to the tip of the second arm 3 of the arms 11 so as to be rotatable in the vertical direction by a link 42, and a scraping plate 51 is attached to the tip of the joint portion 4 so as to be rotatable in the horizontal direction. attached to. In the figure, numeral 41 indicates a cylinder for rotating the joint part 4 with respect to the second arm 3, and a cylinder for horizontally rotating the scraping plate 51 is built in the joint part 4, although not shown.

The scraping plate 51 is a flat box with a thin plate at the tip, and compressed fluid jetting nozzles 52 whose scraping surfaces are in the jetting direction are integrally arranged in parallel thereon.

On the other hand, a water tank 6 is provided in the rear part of the revolving body 1 in an overhanging manner so as to protrude from the rear end, and also serves as a counterweight. It is connected by a hose to a compressed fluid jet nozzle 52 via a driven high-pressure water pump 8 . Note that this hose is installed along the arm 11 or built in so as to follow the movement of the arm 11.

The scraping plate 51 is operated by the cylinders 21, 31, 41, etc., and the high-pressure water pump 8 is operated from the driver's seat 9 via the hydraulic motor 7 to adjust the jetting from the compressed fluid jetting nozzle 52.

Next, the method of use and operation will be explained.

If a large amount of deposits are firmly attached to the wall surface, first remove some of the deposits using the scraping plate 51, and then operate from the driver's seat 9 to spray high-pressure water from the compressed fluid jet nozzle 52. Remove remaining deposits by spraying.

The movement of the scraping plate 51 in the horizontal direction is achieved by first rotating the rotating body 1 to direct the entire arm 11 toward the work area, and fine adjustments are made using the joint part 4 built in as shown in FIG. This is done by moving the scraping plate 51 itself in the horizontal direction using a cylinder, and in the vertical direction, the first arm 2 is moved up and down by the cylinder 21, and the second arm 3 is bent by the cylinder 31. For delicate adjustments, use cylinder 4
1. This is done by the joint part 4 by the link 42, and by moving forward and backward by the traveling means 10 in the front-rear direction, or by extending and contracting the second arm 3.

In this way, the scraping plate 51 can be freely moved in all directions of the X, Y, and Z axes,
At the same time, the compressed fluid jet nozzle 52 also moves.

In addition, when it is difficult to remove deposits such as deposits between reinforcing ribs on the wall surface with the scraping plate 51, high pressure water jetted from the compressed fluid jetting nozzle 52 is especially used to remove the deposits. It is also possible to remove deposits using the scraping plate 51 while preventing the generation of dust by jetting high-pressure water from the nozzle 52.

In addition, by spraying a small amount of high-pressure water from the compressed fluid jetting nozzle 52 to moisturize the deposits, and then removing the deposits with the scraping plate 51, the scraping plate 51 removes the deposits. Dust generated during removal work can be prevented.

[Effect of idea]

As mentioned above, the deposit removal device of the present invention is
It is possible to use a scraping plate and high-pressure water depending on the situation of the deposits and the condition of the wall surface. Moreover, it is possible to use a device that sprays high-pressure water and a device equipped with a scraping plate separately, or to use a device that sprays high-pressure water and a device equipped with a scraping plate separately. Unlike the case where the shape is changed and used each time, the different shapes can be used easily and instantaneously at any time as needed without interrupting the work, so there is no reduction in work efficiency.

Furthermore, if high-pressure water is used only when necessary depending on the condition of the wall surface, deposits are less likely to be scattered over a wide area and puddles are less likely to form, making it easier to treat the floor surface.

In addition, since there is no need to equip the device itself with a large-capacity water tank other than a counterweight to secure a large amount of water, the entire device is compact, making it easy to work in a narrow ship hatch, and is safe with no risk of capsizing. work can be done.
