Description

Technical Field

[0001] The utility model relates to the technical field of ships, and particularly relates to a rotary hanging beam structure. Background Art

[0002] Due to the increasingly strict environmental protection regulations, more and more environmental protection equipment is arranged in the engine room. How to make the most efficient use of the space in the engine room has gradually become an urgent problem to be solved. Taking the maintenance of the seawater filter on the main seawater pipe of a container ship as an example, usually a hanging beam or several eye plates need to be arranged, and the seawater filter is lifted by a chain block hanging on the hanging beam or the eye plate.

[0003] However, there are two disadvantages in maintaining the seawater filter in this way:

[0004] First, the required hanging beam has a long size or a large number of eye plates are needed. Taking the hanging beam for lifting and barging the seawater filter as an example, the hanging beam needs to be arranged from above the seawater filter all the way to the filter storage area, and the arrangement of the long hanging beam also poses a great challenge to the arrangement of the engine room pipelines.

[0005] Second, after the seawater filter is lifted out through the hanging beam or the eye plate, the seawater filter needs to be fixed in a suitable and safe position. Since the seawater filter of a large container ship has a large size, a blank area needs to be deliberately vacated in the narrow bottom space of the engine room to place the seawater filter, which causes a great waste of the already limited engine room space. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to overcome the above defects existing in the prior art and provide a rotary hanging beam structure.

[0007] The utility model solves the above technical problem through the following technical solutions:

[0024] The following is a preferred embodiment, and the present utility model will be described more clearly and completely in conjunction with the attached drawings.

[0025] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, a rotary hanging beam structure includes an upper base 10 and a lower base 20 fixedly connected to the hull structure. An oval tube 31 is fixedly provided on the upper base 10, and a support tube 32 is fixedly provided on the lower base 20.

[0026] The rotary hanging beam structure further includes a hanger 40 that can rotate around the oval tube and the support tube and can be disassembled from the oval tube and the support tube.

[0027] The hanger 40 includes a vertical tube 41, a horizontal tube 42, and an inclined tube 43; the upper part of the vertical tube 41 is inserted into the oval tube 31; the lower part of the vertical tube 41 is inserted into the support tube 32; both the horizontal tube 42 and the inclined tube 43 are fixedly connected to the vertical tube 41, and the inclined tube 43 is fixedly connected to the horizontal tube 42.

[0028] The vertical tube 41, the horizontal tube 42, and the inclined tube 43 form a stable triangular mechanism.

[0029] The lengths, outer diameters, and wall thicknesses of the vertical tube 41 and the horizontal tube 42 are the same. The included angle a between the inclined tube 43 and the horizontal tube 42 is 25° to 35°. A lifting lug 44 is fixedly provided at the bottom of the horizontal tube 42.

[0030] The horizontal tube 42 and the inclined tube 43 are located between the oval tube 31 and the support tube 32.

[0031] The distance from the top of the inclined tube 43 to the bottom of the oval tube 31 is greater than the distance between the bottom of the horizontal tube and the bottom of the vertical tube.

[0032] The distance from the top of the inclined tube 43 to the bottom of the oval tube 31 is H1, and the distance between the bottom of the horizontal tube and the bottom of the vertical tube is H2, where H1 - H2 ≥ 50 mm.

[0033] The inner diameter of the arc part of the oval tube 31 is greater than the outer diameter of the vertical tube 41. The maximum distance between the vertical tube and the oval tube is D, where D ≥ 200 mm.

[0034] The inner diameter of the support tube 32 is greater than the outer diameter of the vertical tube 41. The difference between the inner diameter of the support tube and the outer diameter of the vertical tube is not less than 5 mm.

[0035] The upper base 10 includes a first web 11 and two first plate-like members 12. One end of each of the two first plate-like members 12 is fixed to the first web 11, and the other end of each of the two first plate-like members 12 is fixed to the waist tube 31. The first web 11 is fixed to the hull structure 50. The first web and the two first plate-like members form a triangle.

[0036] The lower base 20 includes a second web 21 and two second plate-like members 22. One end of each of the two second plate-like members 22 is fixed to the second web 21, and the other end of each of the two second plate-like members 22 is fixed to the support tube 32. The second web 21 is fixed to the hull structure 50. The second web and the two second plate-like members form a triangle.

[0037] When the rotating beam structure is in operation, the vertical tube of the hanger is inserted into both the waist tube and the support tube. The vertical tube can rotate freely within the waist tube and the support tube, so the hanger can rotate freely around the waist tube and the support tube. The object to be moved can be fixed to the eye plate. After the hanger rotates, the object can be easily moved to the desired location.

[0038] When the hanger is not needed, it can be removed from the waist tube and support tube. Figures 4 to 5 The hanger can be removed by following the steps below. Figure 4 As shown, first lift the hanger upwards. Since the distance from the top of the oblique tube to the bottom of the waist tube is greater than the distance from the bottom of the horizontal tube to the bottom of the vertical tube, after lifting the hanger upwards, the bottom of the hanger (i.e. the bottom of the vertical tube) is located above the support tube. Figure 5 As shown, rotate the hanger outward by an angle b of about 5°, the bottom of the hanger can be separated from the support tube, and the vertical tube of the hanger can be pulled out of the waist tube. The hanger can then be removed smoothly.

[0039] When the hanger is required, you can follow the Figures 5 to 4 Follow the above steps in reverse order to install the hanger.

[0040] The rotary hanging beam structure of the utility model has the advantages of being detachable and plug-and-play, and can be widely used in various working areas.

[0041] The utility model adopts steel pipes commonly used in shipyards, and manufactures a rotary hanging beam after the steel pipe specifications are selected through force analysis, which greatly saves the space occupied by ordinary hanging beam tracks or eye plates.

[0042] After the rotating lifting beam structure of the utility model lifts the equipment, the equipment can be lifted away from its working area and fixed in the air by a steel wire rope, which greatly saves the space on the bottom floor of the cabin.

[0043] Although the specific embodiments of the present utility model have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present utility model is defined by the appended claims. Without departing from the principle and essence of the present utility model, those skilled in the art can make various changes or modifications to these embodiments, but such changes and modifications all fall within the protection scope of the present utility model.
