Description

Technical Field [0001] The present invention relates to a surface grinding machine for deck of ship,

The present invention relates to a grinding apparatus, and more particularly, to a surface grinding apparatus for a ship deck capable of removing rust formed on a deck by grinding the surface of a deck in close contact with the upper surface of a deck of a ship.

In general, a ship is subjected to a coating process for applying a certain thickness of paint on its surface in order to prevent corrosion and prolong its service life. In order to apply the paint uniformly and stably, the foreign matter After the surface treatment process for removing the impurities, the coating is performed.

In order to carry out the surface treatment process, conventionally, the surface of the vessel is polished by hand while grinding the grinder operated by air supply, and the impurities are removed, and then the paint is applied.

However, since the surface treatment process of the vessel takes a long time, not only the efficiency and productivity of the work are significantly lowered but also the worker is exposed to the musculoskeletal diseases, environmental pollution caused by paint dust, The surface of the ship is not uniformly polished and the painting operation is not stabilized. As a result, the paint is peeled off after a lapse of time, Costly burden. Also, there are frequent safety accidents such as injury of the worker due to the rotating blade of the grinder rotating at a high speed, and many problems such as causing respiratory diseases due to foreign substances or dust removed Respectively.

Also, in order to remove the rust formed on the deck surface of the ship, the surface treatment process was performed using a predetermined grinder. Since the surface of the deck structure is not evenly uniformed, There is a problem that the efficiency is lowered.

Korean Utility Model Publication No. 20-2000-0019572 (published on November 15, 2000) Korean Patent Publication No. 10-2010-0010578 (published on February 02, 2010) Korean Patent Publication No. 10-2013-0057207 (published on May 31, 2013)

The object of the present invention which is devised to solve the above problems is to provide a surface grinding apparatus for a ship deck capable of evenly grinding even a bent portion where the deck surface of a ship has a different height.

According to an aspect of the present invention, there is provided a portable terminal comprising: a housing having a handle provided at an upper end thereof and a conveying wheel installed at a lower end of the housing, the housing having a predetermined accommodation space therein; And a grinding means for grinding the upper surface of the deck of the ship at the bottom of the grinding wheel, wherein the grinding means comprises at least one disc-shaped grinding wheel, a connecting joint coupled to the upper portion of the grinding wheel, And a drive motor for rotationally driving the spline gear.

The connection joint is characterized by being a universal joint.

The spline gear is characterized by having an elastic spring coupled to the outer diameter.

This design has the effect of increasing the efficiency of the work because the surface grinding can evenly be performed even to the bent portion where the deck surface of the ship has different height.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated herein and form a part of the specification, illustrate preferred embodiments of the present invention and, together with the detailed description of the invention, serve to further the understanding of the technical idea of the invention. And shall not be construed as interpretation.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a preferred embodiment of a surface grinding apparatus for a ship deck according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing a surface grinding apparatus of a ship deck according to an embodiment of the present invention, FIG. 2 is a perspective view showing grinding means in a surface grinding apparatus of a ship deck according to an embodiment of the present invention, FIG. 4 is an operational state diagram of a grinding means in a surface grinding apparatus of a ship deck according to an embodiment of the present invention. FIG. 4 is an exploded perspective view showing a grinding means in a surface grinding apparatus of a ship deck according to an embodiment of the present invention.

1 to 4, a surface grinding apparatus for a ship deck according to a preferred embodiment of the present invention comprises a housing 100 and a grinding means 200, which will be described in detail as follows .

The housing 100 includes a handle 110 and a conveying wheel 120.

The housing 100 is provided with a predetermined receiving space therein and a handle 110 capable of being held by a worker is installed at an upper end of the housing 100. A conveying wheel 120 is installed at a lower end of the housing 100.

The grinding means 200 includes a grindstone 210, a connecting joint 220, a spline gear 230, and a driving motor 240.

The grindstone 210 grinds the surface of the deck in contact with the upper surface of the deck of the ship, and is located at the bottom of the grinding means 200, and is formed in a disc shape. At this time, at least one or more grinding wheels 210 may be provided.

The coupling joint 220 is preferably a universal joint. The coupling joint 220 is hinged to the upper portion of the grindstone 210 at the lower end thereof. The grindstone 210 is freely pivoted at a predetermined angle to uniformly grind the curved surface of the deck surface. You can do it.

The spline gear 230 is coupled to the upper portion of the connection joint 220 for power transmission. The spline 230 cuts a plurality of lines of the key directly from the shaft, and the shaft and the boss are slip- To be able to do so.

That is, the spline gear 230 is a shaft, and the connection joint 220 serves as a boss, so that a groove formed at a predetermined depth inward in the upper end of the connection joint 220, The coupling joint 220 can vertically move up and down about the spline gear 230 by the spline gear engagement so that the position of the grinding stone 210 can be raised and lowered to uniformly grind even the bent surfaces of the deck will be.

The driving motor 240 is connected to the spline gear 230 to rotate the spline gear 230 and is preferably connected to the upper end of the spline gear 230.

Meanwhile, an elastic spring 231 may be coupled to the outer diameter of the spline gear 230.

This is because when the grinding wheel 210 is located at the peak of the deck surface when grinding the upper surface of the deck of the ship by using the compression and restoring force of the spring 231, The coupling joint 220 is rapidly lowered due to the restoring force of the spring 231 so that the grinding wheel 210 is moved downward by the restoring force of the spring 231. As a result, It is possible to perform grinding in a state in which it is as close as possible to the surface of the deck.

While the present invention has been described in connection with the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims. And such variations and modifications are intended to fall within the scope of the appended utility model registration claims.
