得られる。As shown in FIG. 1, the nozzle 1 is assembled in advance on the ground in upper and lower blocks A and B and left and right blocks C and D, that is, divided into four parts. At this time, the four divided blocks A to D are arranged in a ring shape as shown in FIG. 1, and the accuracy of each block A to D is checked. By the way, nozzle 1
The important points in terms of performance are angle of attack, front and rear clearance,
This is the tip clearance, and the angle of attack is checked when each block A-D is assembled on the ground, so each block A
--When installing D on the hull, it is necessary to pay attention to the front and rear clearance and tip clearance, and at the same time install it so that the rear end surface of the nozzle is perpendicular to the axis of the propeller. The present invention has been made in order to facilitate the installation work of each block A to D by suppressing the front and rear clearance, tip clearance, and points perpendicular to the propeller axis. The installation and positioning order of the nozzles [each block A-D] will be explained below. First, remove the bonnet 3 of the propeller 2, and use a scribing member (not shown) like a compass pencil on both the front and rear surfaces of the propeller 2. Thereafter, the support fitting 5 is attached to the front surface of the rudder plate 4, and by rotating the propeller 2, circular marks are drawn on the rear surface of the boss 7 of the stern frame 6 and the front surface of the support fitting 5, respectively, using the marking member. Insert a note and bring out the same axis as the axis of the propeller 2. At the same time, mark the propeller tip position etc. on the shoe piece 16 and the top surface of the stern frame 6 using a marking member separately provided on the propeller 2.
Furthermore, the centers of the shoe piece 16 and the stern frame 6 are marked by appropriate means. Next, the propeller 2
Then, the rotating shaft is removed from between the boss 7 and the steering plate 4, and centering fittings 8 and 9 are attached to the front surface of the support fitting 5 and the rear surface of the boss 7, respectively, in alignment with the markings. Thereafter, both ends of the centering shaft 12 are supported by the centering fittings 8 and 9 via bearings 10 and 11. At this time, the centering shaft 12 is located on the same axis as the rotation axis of the propeller 2. Next, a windmill-shaped positioning jig 13 is attached to this centering shaft 12.
Attach. This positioning jig 13 is assembled into a circular shape by using two semicircular pieces as shown in FIG. 5 and holding them together on the centering shaft 12 as shown in FIG. It has a ring-shaped bent piece 14 on its outer periphery that is oriented perpendicularly to the rear end surface of the nozzle to be attached later. Also, this positioning jig 1
3 is rotatable around a centering shaft 12. The mounting position of this positioning jig 13 is determined at a position separated by a predetermined distance from the rear end surface of the nozzle to be mounted later.
After the positioning jig 13 is mounted on the centering shaft 12 in this manner, the blocks A to D shown in FIG. 1 are sequentially mounted on the stern portion of the hull 15. The order of installation is to first install the lower block A. The lower block A is positioned between the rear end surface of the lower block A and the bent piece 14 of the positioning jig 13. Set the lower block A so that the
Align the center of the marked shoe piece 16 with the 180 pin position of the lower block A (see Figure 1),
Look at the horizontal level of the flat part of lower block A. If the dimensions, center and horizontality are good, the lower block A is temporarily attached onto the shoe piece 16 via the pedestal 17. Next, attach the upper block B. At this time, the center rib B' projecting upward from the upper block B is aligned with the marking position on the upper surface of the stern frame 6. Also, align the center rib B'' vertically using a plumb bob, and then connect the rear end surface of the lower block B to the bent piece 14 of the positioning jig 13.
and set the same predetermined interval as that of the lower block A. If the internal dimensions and rear end surface are good, it is temporarily attached to the hull 15 of the upper block B. In addition, a total of four reinforcements are installed between both sides (both sides) of the center rib B'' and the hull 15. In this way, the lower block A and the upper block B
After temporarily attaching the blocks, the left side block Y block C and the right side block D are installed in this order. Both blocks C and D
When installing the lower block A, there is a gap between the rear end surfaces of the blocks C and D and the bent piece 14 of the positioning jig 13.
1. Set the upper blocks C and D at the same predetermined intervals as upper block B, and temporarily attach both blocks C and D to the hull 15. After completing the mounting of each block A to D, the dimensions of the nozzle 1 formed by all blocks A to D are measured, and if the dimensions are defective, they are corrected, and after the correction is completed, hardening is performed. After the hardening is completed, the dimensions of the nozzle 1 are measured. Check the circular dimension and perpendicularity of the rear end surface using the positioning jig 13. After measuring the dimensions, each block A to D is restrained with reinforcement. Next, reinforcement for welding each block A to D is attached. Perform welding between blocks A and D symmetrically on both sides. After welding between blocks A and D is completed, the outer plates of the nozzle block joint and the joint with the hull 15 are restored and welded to blocks A and D. The welding order is symmetrical on both sides from the lower block A upwards. After that, the cover plates are restored in the order of upper block B1 and lower block A. Thereafter, each of the reinforcement and welding jigs described above is removed from the nozzle 1, and the installation accuracy such as final dimensions is measured using the positioning jig 13 and the like, and if there are no defects, the installation of the nozzle 1 is completed. If there is a problem, you can correct it. The mounting positioning method for the stern nozzle of the present invention can be carried out as described above, and the nozzle can be easily mounted without removing the rudder plate, and the rotational axis is set in advance at the propeller axis. A highly accurate mounting position can be obtained using the provided positioning jig.
