Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to an integrated structure of a radar mast and a ladder under a compass deck of a container ship. Background Art

[0002] The radar mast of a container ship is usually arranged on the compass deck. The specific structure is as follows: Figure 1 and Figure 2 As shown, the support column of the radar mast 10 is fixed to the compass deck 12, and the support column of the radar mast 10 is a certain distance away from the rear support wall 13 of the compass deck. The support column 11 of the radar mast is usually not connected to the ladder wall structure 14 below the compass deck. The support column 11 of the radar mast is usually supported on the longitudinal girder or longitudinal bone of the compass deck, and the rigidity of the supporting position is weak, resulting in a large vibration response of the radar mast.

[0003] right Figure 1 The vibration response finite element analysis of the radar mast was carried out, and the results are as follows Figure 3 , Figure 4 As shown. Figure 3 , Figure 4 It can be seen that the radar mast vibrates violently in the longitudinal and lateral directions, which causes great harm and may even cause the radar mast to break in extreme cases.

[0004] The current solution is usually to make the support structure of the radar mast extremely complicated, which has the defects of complex structure, heavy weight and high manufacturing cost. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the above-mentioned defects in the prior art and provide an integrated structure of a radar mast and a ladder under a compass deck of a container ship.

[0006] The present invention solves the above technical problems through the following technical solutions:

[0007] A container ship radar mast and a ladder under a compass deck integrated structure, comprising a radar mast arranged on the compass deck, the radar mast comprising a plurality of support columns, the support columns being located at the bottom of the radar mast, the support columns close to the rear support wall of the compass deck being the rear support columns, and the support columns located in front of the rear support columns being the front support columns; the rear support columns and the front support columns are both fixedly arranged on the compass deck; a ladder wall structure for enclosing the ladder is arranged under the compass deck; the ladder wall structure comprises a left longitudinal wall, a transverse wall and a right longitudinal wall connected in sequence, the two ends of the left longitudinal wall being respectively fixedly connected to the rear support wall and the transverse wall of the compass deck; the two ends of the right longitudinal wall are respectively fixedly connected to the rear support wall and the transverse wall of the compass deck wall; the transverse wall is parallel to the rear supporting wall of the compass deck; the left longitudinal wall, the transverse wall, the right longitudinal wall and the rear supporting wall of the compass deck form a rectangle; the left longitudinal wall and the right longitudinal wall are symmetrically distributed on both sides of the centerline of the ship; the centerline of the ship is perpendicular to the transverse wall; there are two rear supporting columns and two front supporting columns; the two rear supporting columns are symmetrically distributed on both sides of the centerline of the ship, and the two front supporting columns are symmetrically distributed on both sides of the centerline of the ship; the central axes of the two rear supporting columns coincide with the intersection lines of the left longitudinal wall and the rear supporting wall of the compass deck, and the intersection lines of the right longitudinal wall and the rear supporting wall of the compass deck respectively; the central axes of the two front supporting columns coincide with the intersection lines of the left longitudinal wall and the transverse wall, and the intersection lines of the right longitudinal wall and the transverse wall respectively.

[0008] The center axis of the rear support column is parallel to the center axis of the front support column.

[0009] The central axis of the rear support column coincides with the rear support wall of the compass deck.

[0010] The center axis of the front support column coincides with the transverse wall.

[0011] The central axis of the front support column is perpendicular to the compass deck.

[0012] The central axis of the rear support column is perpendicular to the compass deck.

[0013] The intersection of the centerline and the transverse wall is the midpoint of the transverse wall.

[0014] The centerline of the ship is perpendicular to the transverse walls.

[0015] The left and right longitudinal walls are parallel to the centerline of the ship.

[0016] The front support column and the compass deck are connected by welding, and the rear support column and the compass deck are connected by welding.

[0017] The beneficial effects of the present invention are as follows: the present invention adjusts the width of the ladder under the compass deck so that the ladder wall structure is symmetrical along the centerline of the ship; and adjusts the positions of the support columns of the radar mast so that the central axes of the four support columns are aligned with the four corner points of the ladder wall structure. In this way, the four support columns of the radar mast are all supported on a stronger structure, ensuring the lateral and longitudinal stiffness of the support points, and effectively reducing the vibration response of the radar mast. The present invention has a simple structure and low manufacturing cost, and can achieve the effect that can only be achieved by a complex and bulky structure with a simple structure.

[0026] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0027] like Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a container ship radar mast and a ladder under a compass deck are integrated into a structure, which includes a radar mast 20 arranged on a compass deck 30. The radar mast includes a plurality of support columns, and the support columns are located at the bottom of the radar mast. The support column close to the rear support wall 31 of the compass deck is the rear support column 21, and the support column located in front of the rear support column is the front support column 22; the rear support column 21 and the front support column 22 are both fixedly arranged on the compass deck 30.

[0028] A stairway enclosure structure 40 for enclosing the stairway is provided below the compass deck 30; the stairway enclosure structure 40 comprises a left longitudinal wall 41, a transverse wall 42 and a right longitudinal wall 43 which are connected in sequence, and the two ends of the left longitudinal wall 41 are respectively fixedly connected to the compass deck rear support wall 31 and the transverse wall 42; the two ends of the right longitudinal wall 43 are respectively fixedly connected to the compass deck rear support wall 31 and the transverse wall 42.

[0029] The transverse wall 42 is parallel to the rear support wall 31 of the compass deck; the left longitudinal wall 41, the transverse wall 42, the right longitudinal wall 43 and the rear support wall 31 of the compass deck form a rectangle; the left longitudinal wall 41 and the right longitudinal wall 43 are symmetrically distributed on both sides of the centerline 50; the centerline 50 is perpendicular to the transverse wall 42.

[0030] There are two rear support columns 21 and two front support columns 22 ; the two rear support columns 21 are symmetrically distributed on both sides of the ship's centerline 50 , and the two front support columns 22 are symmetrically distributed on both sides of the ship's centerline 50 .

[0031] The central axes of the two rear support columns 21 coincide with the intersection lines of the left longitudinal wall 41 and the rear support wall 31 of the compass deck, and the intersection lines of the right longitudinal wall 43 and the rear support wall 31 of the compass deck, respectively.

[0032] The central axes of the two front support pillars 22 coincide with the intersection lines of the left longitudinal wall 41 and the transverse wall 42 and the intersection lines of the right longitudinal wall 43 and the transverse wall 42 , respectively.

[0033] The center axis of the rear support column 21 is parallel to the center axis of the front support column 22. The center axis of the rear support column 21 coincides with the rear support wall 31 of the compass deck.

[0034] The center axis of the front support column 22 coincides with the transverse wall 42. The center axis of the front support column 22 is perpendicular to the compass deck 30.

[0035] The central axis of the rear support column 21 is perpendicular to the compass deck 30 .

[0036] The intersection of the centerline 50 and the transverse wall 42 is the middle point of the transverse wall.

[0037] The left longitudinal wall 41 and the right longitudinal wall 43 are both parallel to the centerline 50 .

[0038] The front support column 21 is connected to the compass deck 30 by welding, and the rear support column 22 is connected to the compass deck 30 by welding.

[0039] The finite element analysis diagram of the longitudinal vibration response of this embodiment is as follows: Figure 7 The finite element analysis diagram of the lateral vibration response of this embodiment is shown in FIG. Figure 8 shown. Figure 8 The perspective is from the stern to the bow.

[0040] from Figure 7 and Figure 8 It can be seen that the radar mast structure can basically maintain structural deformation under longitudinal vibration and lateral vibration response.

[0041] In this embodiment, the width of the stairway under the compass deck is adjusted so that the stairway wall structure is symmetrical along the centerline of the ship; and the positions of the support columns of the radar mast are adjusted so that the central axes of the four support columns are aligned with the four corner points of the stairway wall structure.

[0042] In this way, the four supporting columns of the radar mast are all supported on a stronger structure, ensuring the lateral and longitudinal stiffness of the supporting points, which can effectively reduce the vibration response of the radar mast.

[0043] The invention has a simple structure and low manufacturing cost, and can achieve the effect that only a complex and bulky structure can achieve with a simple structure.
