Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship engineering, in particular to a ship side thruster mounting structure and a ship side thruster mounting method. BACKGROUND

[0002] The ship side thruster is a device for assisting the ship to turn. The widely used ship side thruster is a guide cylinder type side thruster. The guide cylinder type side thruster is provided with a guide cylinder at the bow of the ship. The guide cylinder penetrates the ship body in the width direction of the ship. The central axis of the guide cylinder is perpendicular to the longitudinal section of the ship body. The side thruster is arranged in the guide cylinder. Figure 1 As shown in the figure, the existing ship bottom structure arrangement type is provided with a rib plate 300 at each rib position line. The rib plate 300 is arranged in the width direction of the ship body 100. When the guide cylinder 200 is installed, the rib plate 300 needs to be welded with the outer bottom wall of the guide cylinder 200. In order to ensure that the rib plate 300 can stably support the guide cylinder 200, multiple rib plates 300 are arranged at intervals in the length direction of the ship body 100 under the guide cylinder 200. The multiple rib plates 300 form a support structure for supporting the guide cylinder 200. Since the guide cylinder 200 needs to bear a large load during work, the welding joints between each rib plate 300 and the outer wall of the guide cylinder 200 require double continuous welding. The narrow and long sealed space is formed between the front and rear adjacent two rib plates 300 under the guide cylinder 200. In order to weld the weld between the rib plate 300 in the sealed space and the guide cylinder 200, a manhole needs to be arranged on each rib plate 300 deviated from the center of the guide cylinder 200. The welder enters each narrow space through the manhole to perform welding.

[0003] Due to the limitation of the bow structure, the space at the bottom of the guide cylinder 200 is very narrow. The narrow and long space forms a shape with high middle and low sides in the width direction of the ship body 100. It is difficult to perform welding in the low side area, and it is difficult to ensure the welding quality. Moreover, the air in the narrow and long space is poor, the labor intensity is high, and the efficiency is low, resulting in high labor cost. SUMMARY

[0004] The technical problem to be solved by the present application is that the support structure for supporting the guide cylinder and the guide cylinder form a narrow and long space with low sides and high middle. The worker needs to enter the narrow and long space through the manhole to perform welding, which is not convenient for ensuring the welding quality and has high welding labor intensity.

[0044] The bottom longitudinal girder 1 is fixed on the hull 100 in the front-rear direction and located at the center of the width direction of the hull 100. The bottom longitudinal girder 1 belongs to the existing structure of the hull 100, penetrates the hull 100 in the front-rear direction, and ensures the overall strength of the hull 100.

[0045] The left and right sides of the bottom longitudinal girder 1 are each provided with the center rib plate 2. The flow guide cylinder 200 is arranged opposite the center rib plate 2 in the up-down direction. The lower end of the center rib plate 2 is fixed on the hull 100, and the upper end of the center rib plate 2 is welded to the lower end of the flow guide cylinder 200. The center rib plate 2 separates the lower end of the flow guide cylinder 200 into a front region 201 and a rear region 202. Specifically, the center rib plate 2 can be two, and the two center rib plates 2 are arranged symmetrically about the bottom longitudinal girder 1. The center rib plate 2 can also be one, and a mounting groove is arranged in the middle of the center rib plate 2, so that the bottom longitudinal girder 1 is welded in the mounting groove.

[0048] Specifically, the projection of the fairing 200 in the vertical direction is located behind the first front rib plate 31, and the first interval can communicate each first subspace 1001, so that a manhole with a large size does not need to be arranged on each first reinforcing plate 41, thereby avoiding the adverse effect of the large-size manhole on the strength of the first reinforcing plate 41;

[0049] The bottom longitudinal girder 1 is fixed with first rear rib plates 51 on the left and right sides, and the first rear rib plates 51 are arranged behind the center rib plate 2, and the interval between the first rear rib plate 51 and the center rib plate 2 in the front-rear direction forms a second space 2000; specifically, the first rear rib plate 51 can be two, and the two first rear rib plates 51 are arranged symmetrically about the bottom longitudinal girder 1, or the first rear rib plate 51 can be one, and a mounting groove is arranged in the middle of the first rear rib plate 51, and the bottom longitudinal girder 1 is welded in the mounting groove;

[0050] Each second reinforcing plate 42 is arranged in the second space 2000, and the second reinforcing plate 42 and the bottom longitudinal girder 1 divide the second space 2000 into a plurality of second subspaces 2001 arranged in sequence from left to right, and the upper end of each second reinforcing plate 42 is welded with the rear region 202; specifically, each second reinforcing plate 42 extends in the front-rear direction, the front end of each second reinforcing plate 42 is welded with the center rib plate 2, the rear end of each second reinforcing plate 42 is welded with the rear rib plate, and the lower end of each second reinforcing plate 42 is welded with the ship body 100; by changing the thickness of each second reinforcing plate 42, the support strength of the ship side thruster mounting structure of the embodiment on the fairing 200 can be adjusted, and the distance between two adjacent second reinforcing plates 42 can be adjusted so that the distance is convenient for workers to weld; and by thickening the thickness of the second reinforcing plate 42 and the first reinforcing plate 41, the center of gravity of the ship is lower and the safety is better while the strength is ensured;

[0051] The first rear rib plate 51 has a second interval in the front-rear direction with the fairing 200, and the second interval forms a second welding channel 4000 for a human body to enter each second sub-space 2001; specifically, the projection of the fairing 200 in the vertical direction is located in front of the first rear rib plate 51, and the second interval can communicate each first sub-space 1001, so that a manhole with a large size does not need to be arranged on each second reinforcing plate 42, thereby avoiding the adverse effect of the large-size manhole on the strength of the second reinforcing plate 42.

[0052] The first sub-space 1001 and the second sub-space 2001 are shallow in depth and short in length, which facilitates welding, improves the working environment, reduces the construction difficulty, and ensures the welding quality, while meeting the support strength requirement of the ship side thruster, and the manufacturing process of the ship side thruster mounting structure of the embodiment is simpler; in addition, the ship side thruster mounting structure of the embodiment does not damage the bottom longitudinal 1, and the stability of the ship structure is maintained.

[0053] To further improve the support strength of the ship side thruster mounting structure of the embodiment, an elbow plate is welded between the front end of each first reinforcing plate 41 and the first front rib plate 31, and between the rear end of each first reinforcing plate 41 and the center rib plate 2; an elbow plate is welded between the front end of each second reinforcing plate 42 and the center rib plate 2, and between the rear end of each second reinforcing plate 42 and the rear rib plate.

[0054] To further improve the support strength of the ship side thruster mounting structure of the embodiment, in the embodiment, the ship side thruster mounting structure further comprises a second front rib plate 32 and a plurality of third reinforcing plates 43; the second front rib plate 32 is fixed to the left and right sides of the bottom longitudinal 1, and the second front rib plate 32 is located in front of the first front rib plate 31; each third reinforcing plate 43 is arranged between the second front rib plate 32 and the first front rib plate 31, and each third reinforcing plate 43 is arranged in sequence and spaced apart from left to right, the front end of each third reinforcing plate 43 is fixed to the second front rib plate 32, and the rear end of each third reinforcing plate 43 is fixed to the first front rib plate 31.

The right-angled trapezoidal configuration of the third and fourth reinforcing plates 43, 44 not only ensures the support strength of the third and fourth reinforcing plates 43, 44 for the first front and first rear ribs 31, 51, but also reduces the weight of the third and fourth reinforcing plates 43, 44. To further reduce the weight of the hull 100 structure, in this embodiment, each first and second reinforcing plate 41, 42 is provided with a weight-reducing hole. These holes can be circular, triangular, or other irregular shapes. The size of a single weight-reducing hole is smaller than a manhole.
