JPS6387392A - Loading of rudder plate and propeller - Google Patents

Abstract

PURPOSE:To facilitate installation and reduce the using time of a crane and also facilitate the fitting work by using a surface plate in which a rudder plate or a propeller is loaded on one side and a balance weight is loaded on the other side. CONSTITUTION:A rudder plate R mounted on a surface plate 1 is loaded in erection state. A balance weight balanced with the rudder plate R is loaded onto the opposite side, keeping the suspension center of the surface plate 1 interposed. Then, the surface plate 1 is pulled up by a suspending wire 3 by winding up a crane hook 4, and the surface plate 1 is separated from the ground horizontally. Through the gradual horizontal shift in this state, the rudder plate R is separated from a projecting rudder shaft 5, and inserted under a stern 6, keeping a little gap from the ground. After reaching under a regular position, the rudder plate R is suspended by a chain block installed at the stern 6, then the chain block is wound to pull up the rudder plate R, which is fitted with the rudder shaft 5.

The state (■) is shown when it is hoisted horizontally with a two-point suspension of 3 m. Next, (B) shows a state (2) in which the crane is operated to raise the Prohera P to its normal position and the auxiliary suspension wire 13m is removed. Furthermore, (C') is the hanging piece 1 installed on the stern deck.
Move the crane to the position of the main suspension pulleys 16 and 16a suspended at 4, receive the propeller P at the chain block 17 of the main suspension pulley 16m, and from the state ■ with the crane main suspension wire 16 removed, move the other suspension piece 14m. The auxiliary suspension pulley 18 and the 18m chain block 19 suspended at The respective payout wires 21 and 21ak are expanded and contracted, and the propeller P is moved sideways onto the center line of the ship, resulting in state (2), whereby the propeller Pi is attached to the propeller shaft.

従来例は、プロペラ搭載について説明しているが、舵板
全搭載する場合も同様の方法である。Although the conventional example describes the installation of a propeller, the same method is used when the entire rudder plate is installed.

えて船尾下に引き込み装着するものであった。In this way, the conventional method of mounting rudder plates, propellers, etc. is to first hoist the horizontally placed load horizontally using two points, the main hoisting wire and the auxiliary hoisting wire, and then suspending it from the two hoisting wires. By manipulating wires, the load was raised to its normal state, brought closer to the sides of the stern, and then resuspended to hanging pulleys on both sides of the stern and pulled under the stern for installation.

実施出来ないという問題がある。In the conventional method described above, two cranes for lifting and auxiliary lifting are used for a long period of time, which not only hinders other operations (particularly for ships where the rudder shaft cannot be raised due to the steering mechanism). (When attaching the rudder plate bracket, the length of the outboard protrusion of all the rudder shafts of the vertically erected rudder plate is approximately 1.300 m.
), but in this case, there is almost no clearance in height relative to the deck or the bottom of the culvert (
Example (approximately 500 m) There is a problem in that the conventional suspension mounting method cannot be implemented.

In the figure, reference numeral 1 denotes a surface plate, which has a strong frame girder structure equipped with connecting hardware 2 with hanging wires 3 on both sides. Figure 2 is a plan view of the surface plate 1, in which the rudder plate R is normally placed on one side off the center, and the balance way W for the rudder plate R is placed on the other side. . The hanging wire 3 is connected to a connecting hardware 2 of the surface plate 1 and is hung on a crane hook 4. In the plan view, 5 is the rudder shaft that protrudes from the hull, 6 is the stern, and 7 is the skeletal.

示されるような搭載状態となる。First, the rudder plate R to be mounted on the surface plate 1 is placed in the normal upright position. In this case, as shown in FIG. 6, the upright rudder plate R is held down from both sides by support frames S and Sa to stabilize it. Next, a balance weight Wt balanced with the rudder plate R is placed on the opposite side of the suspension center of the surface plate 1. Thereafter, when the crane hook 4 is hoisted up and the surface plate 1't-lifted by the lifting wire 6, the surface plate 1 is horizontally separated from the ground. By gradually moving horizontally in this state, the rudder plate R avoids the protruding rudder shaft 5 and is inserted under the stern A while maintaining a small gap between it and the ground, as shown in Figure 1. . After reaching the correct position in this way, the rudder plate R is moved to the rudder axle by changing the suspension to the stern block and hoisting the rudder plate R by wrapping it around the stern 6. The mounting state shown in FIG. 4 is achieved.
