Abstract

PURPOSE:To save working time by clamping plural erected cylinder bodies with a top plate and a bottom plate and covering between these cylinder bodies and along the whole periphery of both flanks of the cylinder body and a rear end part with rudder plates. CONSTITUTION:Cylinder bodies 2, 3 are erected in place of vertical rudder bones and fitted being clamped by a top plate 4 and a bottom plate 5. Both flanks of the front cylinder body 2 and the rear cylinder body 3 are connected by a front rudder plate 6, and both flanks of the rear cylinder body 3 and a rear edge part is connected by a rear rudder plate 7. There are further provided with a horizontal rudder bone 9, a rudder head member 10 and a bottom pintle 11. With this constitution, welding work is required only for the straight line parts, thus facilitating welding work, as well as slotting becomes unnecessary, thus shortening working time.

Description

[Detailed description of the invention] Industrial applications The present invention is inspired by the structure of a ship's rudder.

2. Description of the Related Art As shown in FIGS. 4 and 5, a conventional ship's rudder has an inner surface of one rudder plate 21 which is cut in half from the center of the rudder in the direction of travel of the ship and is formed into a predetermined shape in advance. At a predetermined position, the other side of the vertical rudder rib 23 and the horizontal rudder rib 24, each of which has a mounting piece 22 welded to the negative side along its entire length, is welded to form a lattice-like structure of the rudder body 25. After that, it is molded in advance into a predetermined shape so as to cover the skeleton, and holes are drilled vertically and horizontally at predetermined intervals at positions corresponding to the vertical rudder bones 23 and horizontal rudder bones 24, and the inner peripheral end of the slot hole 26 and By welding the outer surface of the mounting piece 22, the remaining rudder plates 27 are fixed to the vertical rudder plates 23 to the horizontal rudder plates 24, and both rudder plates 21.2
The rudder main body 25 was constructed by welding the front cylinder end portion 28 and the front and rear end portions 29 of the rudder main body 25, respectively, and covering the upper and lower surfaces of the rudder main body 25 with a top plate 30 and a bottom plate 31.

In addition, 32 is a rudder stock material, and 33 is a bottom bottle.

Problems to be Solved by the Invention As described above, the rudder main body 25 is constructed by welding and fixing one side of the vertical rudder rib 23 and the horizontal rudder rib 24 to the inner surface of the pre-molded rudder plate 21, and also by welding and fixing one side of the vertical rudder rib 23 and the horizontal rudder rib 24 to the inner surface of the pre-molded rudder plate 21. Since the mounting piece 22 attached to the other side of the rudder frame 24 and the inner peripheral end of the slot hole 26 provided in the remaining rudder plate 27 are welded together, the remaining rudder plate 27 has a large number of slot holes 26. Not only does it take a lot of work time to drill holes, but the rudder body 25
There were problems such as heavy weight.

Therefore, the present invention aims to solve these problems by eliminating the large number of vertical rudder bones 23 and using a plurality of cylindrical bodies standing upright.

Means for Solving the Problem A plurality of cylindrical bodies standing upright instead of vertical bone plates are sandwiched between the top plate and the bottom plate constituting the rudder for ships, and the cylindrical bodies are sandwiched between each cylindrical body and both sides of the cylindrical body and the rear edge. The entire circumference of the rudder is covered with a rudder plate, and as ship rudders become larger, if the rudder requires additional strength, a horizontal rudder frame is provided at a position parallel to the top plate.

Function: Therefore, by eliminating the vertical rudder bones that form the skeleton of the rudder body and using a cylindrical body, the horizontal rudder bones are unnecessary or minimized, making additions simple and reducing weight, and slotted holes for the remaining rudder plates. Since there is no need to drill holes, the work time can be shortened.

Embodiments Below, embodiments of the present invention will be explained based on FIGS. 1 to 3. Reference numeral 1 is a rudder main body, and 2.3 is an upright cylindrical body (hollow or solid can be freely selected) in place of the vertical rudder frame, which is sandwiched between a top plate 4 and a bottom plate 5. 6 is a front rudder plate that connects both sides of the front cylindrical body 2 and the rear cylindrical body 3, 7 is a rear rudder plate that connects both sides of the rear cylindrical body 3 and the rear edge 8, and 9 is a horizontal rudder bone. , 10 is a rudder stock, and 11 is a bottom bottle.

In addition, if necessary, one or both IFs can be installed around the entire circumference as shown in Figure 3! The front cylindrical body 2 and the rear cylindrical body 3 are covered with 12 rudder plates 12, or the rear cylindrical body 3 is covered with one sheet up to the rear edge 8, leaving a part of the front cylindrical body 2. rudder board 1
It is also possible to construct the rudder body 1 by covering it with 2.

Effects of the Invention Since the present invention has the above-described structure, the materials required for a large number of vertical rudder bones and the materials required for horizontal rudder bones are not required, and the welding work is easy only on the straight parts. This eliminates the need to process slot holes in the rudder plate, resulting in significant savings in work time and other outstanding effects.
