Description

Ship canister {CANISTER FOR SHIP}

One embodiment of the present invention relates to a vessel canister capable of improving the assembly quality.

Generally, a canister installed on a ship is installed inside a tunnel formed in a hull so as to be able to ascend and descend. The canister includes a lifting body that is mounted to the hull so as to be able to move up and down by receiving the driving force of the driving means, and a block member installed on the lifting body and provided with a propeller.

Such a canister can be installed so that the canister can be selectively elevated to the inside or outside of the hull by connecting the block member to the lifting body. At least two blocks of the block member are welded to each other, and a hollow cover for protecting a drive shaft that transmits driving force to the propeller is installed at the center.

However, the process of assembling the block member by welding or the like is complicated, and in some cases, when the block member is pinched during the assembling process, it often occurs that a bad operation occurs.

More specifically, the lifting body 100 is provided with a body portion of a driving motor 40 for driving the propeller 50, and the driving shaft 41, which transmits the rotational driving force of the driving motor 40, As shown in Fig. The elevating block 200 may be integrally connected to the elevating main body 100.

FIG. 2 is a perspective view schematically showing a lift block installed in the ship canister of FIG. 1, and FIG. 3 is an exploded perspective view schematically showing the lift block of FIG.

2 and 3, the lifting block 200 may be integrally connected to the lifting main body 100 by welding or the like and may be lifted or lowered together with the lifting or lowering operation of the lifting main body 100. [ The lift block 200 is integrally connected to the lower end of the lifting body 100 and includes a first block 110 and a second block 120 and a hollow cover 130.

The first block 110 is formed to have a cross sectional area smaller than the cross sectional area of the lift block 200 and is coupled to the lower end of the lift block 200.

FIG. 4 is a main part perspective view schematically showing a first section formed in a first block of the lift block of FIG. 2; FIG.

As shown in FIG. 4, the first block 110 has a first concave portion 111 formed on one side thereof. The first concave portion 111 refers to a portion into which a part of a round side surface of a hollow cover 130 to be described later is inserted. A first section 113 protrudes from the first recess 111.

The first slice 113 may protrude at least two along the inner wall surface of the first recess 111. The position at which the first section 113 protrudes may protrude to a position corresponding to an upper portion of the hollow cover 130 to be described later. The first section 113 protrudes from the first recess 111 to fix the hollow cover 130 in a state where the hollow cover 130 is installed and will be described in more detail with reference to the hollow cover 130.

The second block 120 is formed in a cross sectional area smaller than the cross sectional area of the lifting body 100 and is coupled to the lower end of the lifting body 200. More specifically, the second block 120 has a size corresponding to that of the first block 110. One side of the second block 120 is installed in contact with the first block 110, Can be installed in the lifting main body 100.

FIG. 5 is a perspective view schematically showing a second section formed on a second block of the lift block of FIG. 2. FIG.

As shown in FIG. 5, a second recess 121 is formed on one side of the second block 120. The second concave portion 121 refers to a portion into which another portion of the rounded side surface of the hollow cover 130 described later is inserted. The second concave portion 121 may be connected to the first concave portion 111 in the state where the first block 110 and the second block 120 are in contact with each other to form the shape of the through hole 137. [ The reason why the through hole 137 is formed in the lift block 200 by the first concave portion 111 and the second concave portion 121 is that the hollow cover 130 is inserted into the through hole 137 To be inserted. The second slice 123 protrudes from the second recess 121.

The second slice 123 may protrude at least two along the inner wall surface of the second recess 121. The position at which the second slice 123 protrudes may protrude to a position corresponding to the upper portion of the hollow cover 130 to be described later. The second section 123 protrudes from the second recess 121 to fix the hollow cover 130 in a state where the hollow cover 130 is installed and will be described in more detail while explaining the hollow cover 130. In this embodiment, at least two of the first section 113 and the second section 123 may protrude in the same round shape.

The hollow cover 130 has a cylindrical shape and has a mounting space in which a drive shaft 41 is installed and is inserted into a through hole 137 formed by the first block 110 and the second block 120 . The hollow cover 130 protects the driving shaft 41 rotated by the driving force of the driving motor 40 and includes a main cover portion 131 through which the driving shaft 41 passes, And includes a round protrusion 133 for fixing.

The main cover portion 131 is inserted into the through hole 137 and is installed such that the drive shaft 41 passes through the central portion in the longitudinal direction. A round protrusion 133 protrudes from the upper end of the main cover 131.

The round protrusion 133 protrudes from the upper end of the main cover 131 in a round shape. And is connected to the first section 113 and the second section 123 protruding from the through hole 137. A third section 133a (see FIG. 3) protrudes from the round protrusion 133 and can be welded to the first section 113 and the second section. The third section 133a may protrude at equal intervals along the circumference of the round section 133 so as to be connected to the first section 113 and the second section 123. [

FIG. 6 is a sectional view of the main part of the elevation block in a state where the second section and the third section are separated from each other, and FIG. 7 is a schematic view showing a state where the second section and the third section of the elevation block of FIG. It is a lumbar section.

6 and 7, the lifting block 200 of the canister 100 according to an embodiment of the present invention includes a cover 130 protruding from the hollow cover 130 during the process of installing the hollow cover 130, Three segments 133a are welded to the first segment 113 protruding from the first block 110 and the second segment 123 protruding from the second block 120 so that the lift block 200 is assembled It is possible to assemble stably without occurrence of assembly defects such as pinching.

The operation of the ship canister according to one embodiment of the present invention having the above-described structure will be described in more detail as follows.

First, the first block 110 constituting the canister 100 is positioned.

 By positioning the second block 120 in contact with the first block 110, the first concave portion 111 of the first block 110 and the second concave portion 111 of the second block 120 121 and the through-hole 137, respectively.

Next, a cylindrical hollow cover 130 is inserted into the through-hole 137 formed by the first block 110 and the second block 120. Thus, in a state where the hollow cover 130 is inserted between the first block 110 and the second block 120, the third section 133a is divided into the first section 113 and the second section 123 As shown in Fig.

The edges of the first section 113 and the second section 123 are welded to the edge of the third section 133a so that the lift block 200 can be stably assembled .
