Description

Technical Field

[0001] The present invention relates to the technical field of ships, and in particular to an arrangement structure of an open-air main deck in a cargo hold area of a chemical tanker. Background Art

[0002] Existing chemical tankers have an inverted cargo deck structure. The exposed main deck in the cargo area is typically equipped with numerous pipelines, including cargo oil pipelines, which run longitudinally throughout the entire cargo deck area. Therefore, transverse pipe brackets are installed approximately every three meters along the cargo deck area to support and secure the various pipelines. These brackets are appropriately connected to strengthen the overall structure. While this crisscross pattern of pipe brackets ensures strong pipe support, it also hinders lifting operations beneath the brackets.

[0003] Currently, in the cargo deck area of chemical tankers, in addition to major equipment such as cargo oil pumps that require clearing and lifting, much other equipment on the cargo deck is inevitably obscured by the pipe brackets and pipelines above, making lifting difficult, especially in the area of lifeguard lanes. Due to the inverted structure of the cargo deck, the deck is uneven, and lifting equipment or other equipment cannot easily enter the deck area below the pipe brackets. Currently, this handling work is generally completed manually. Once one lifting work is completed, if the next lifting work needs to be carried out, the lifting equipment must be manually moved to another location, which is labor-intensive and inefficient. In addition, the cargo deck contains a lot of relatively heavy equipment and pipelines. Temporary movement of objects not only requires overcoming the weight of the objects themselves, but also the impact of the uneven deck structure on handling, further reducing construction efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a layout structure of the open-air main deck in the cargo hold area of a chemical tanker to solve the problem in the prior art that lifting construction operations in the cargo hold deck area require manual handling of lifting equipment, which is manpower-consuming and inefficient.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] Preferably, the outer peripheral side of the slider is coated with a polytetrafluoroethylene layer.

[0008] Preferably, the slide rail includes a first L-shaped rail and a second L-shaped rail, and the first L-shaped rail and the second L-shaped rail are arranged relative to each other to form a U-shaped groove with the notch facing upward and an opening at the bottom of the groove. The slider is slidably assembled in the U-shaped groove, and the upper part of the rotating lifting ring is installed on the slider through the opening.

[0009] Preferably, the upper thread of the rotating lifting ring is assembled with a stopper, and the stopper is located at the lower side of the bottom opening of the U-shaped channel.

[0025] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0026] like Figure 1 - Figure 3 As shown, an arrangement structure of an open-air main deck in the cargo hold area of a chemical tanker according to an embodiment of the present invention includes a plurality of longitudinal pipe brackets 1 and a plurality of transverse pipe brackets 2. The longitudinal pipe brackets 1 and the transverse pipe brackets 2 are both supported above the open-air main deck 10. A support rod 11 is provided below the longitudinal pipe bracket 1. The support rod 11 is fixed to the open-air main deck 10 and is used to support the longitudinal pipe bracket 1. A pipe bracket 12 for fixing a longitudinal pipeline 121 is provided on the upper surface of the longitudinal pipe bracket 1. The longitudinal pipeline 121 is fixed by the pipe bracket 12. The transverse pipe bracket 2 is connected between two adjacent longitudinal pipe brackets 1. , each longitudinal pipe bracket 1 is connected into a whole through a transverse pipe bracket 2 to strengthen the connection strength of the longitudinal pipe bracket 1; a slide rail 3 is fixed to the lower surface of the longitudinal pipe bracket 1 and the transverse pipe bracket 2, and the slide rail 3 extends along the length direction of the longitudinal pipe bracket 1 or the transverse pipe bracket 2, and the slide rail 3 of the longitudinal pipe bracket 1 is connected to the slide rail 3 of the transverse pipe bracket 2; at least one slider 4 is slidably mounted on the slide rail 3, and a rotating ring 5 is installed on the slider 4. The safe load of the rotating ring 5 is about 1 ton, which can basically cover the construction range above the open main deck 10.

[0027] The rotating lifting ring 5 slides along the slide rail 3 along the slider 4. Since the slide rail 3 of the longitudinal pipe bracket 1 is connected to the slide rail 3 of the transverse pipe bracket 2, the rotating lifting ring 5 can slide from the slide rail 3 of the longitudinal pipe bracket 1 to the slide rail 3 of the transverse pipe bracket 2, or from the slide rail 3 of the transverse pipe bracket 2 to the slide rail 3 of the longitudinal pipe bracket 1, so that the moving track of the rotating lifting ring 5 can cover the area above the open main deck 10 in the cargo hold area. By directly passing the lifting rope 70 through the rotating lifting ring 5 or using it in conjunction with a lifting hoist, the equipment on the open-air main deck 10 can be lifted, including the lifting at the position of the lifesaving channel 30 and the lifting of the pipe 50 on the open-air main deck 10, thereby facilitating the lifting construction operation of objects on the open-air main deck 10, facilitating the movement, fixation and use of objects, avoiding the need to carry lifting equipment on the deck, improving construction efficiency, saving manpower and material resources, and making the lifting operation in the open-air main deck area flexible and simple; in addition, the rotating lifting ring 5 also facilitates the lifting of the construction workers 60, ensuring personnel safety.

[0028] In this embodiment, the longitudinal pipe bracket 1 and the transverse pipe bracket 2 are arranged perpendicularly, facilitating docking of the slide rails 3 of the longitudinal pipe bracket 1 with the slide rails 3 of the transverse pipe bracket 2, allowing the slider 4 to freely switch between the longitudinal pipe bracket 1 and the transverse pipe bracket 2. Multiple longitudinal pipe brackets 1 and multiple transverse pipe brackets 2 each form a frame structure above the main deck area above the cargo hold 20, covering the cargo hold deck's operating area. Preferably, the ends of the transverse pipe bracket 2 extend outward from the longitudinal pipe bracket 1, forming a crisscross-shaped frame structure with the longitudinal pipe bracket 1. Both ends of the transverse pipe bracket 2 and the longitudinal pipe bracket 1 are open and free. The slider 4 can enter the slide rail 3 from either the end of the transverse pipe bracket 2 or the end of the longitudinal pipe bracket 1. This facilitates selecting the location of the longitudinal pipe bracket 1 or transverse pipe bracket 2 for mounting the slider 4, depending on the lifting location, and allows for flexible arrangement of lifting points.

[0029] In this embodiment, Figure 3 As shown, the longitudinal pipe bracket 1 and the transverse pipe bracket 2 are both I-beams, and the slide rail 3 is fixed to the lower surface of the I-beam, making full use of the lower surface space of the I-beam, without the need to set up an additional support structure for the slide rail 3.

[0030] In this embodiment, Figure 2 As shown, at least one longitudinal pipe bracket 1 is positioned directly above the rescue passage 30 in the cargo hold area to facilitate lifting operations at the rescue passage. Optionally, a longitudinal pipe bracket 1 or a transverse pipe bracket 2 is positioned at the hatch 40 of the cargo hold 20 to facilitate lifting operations within the cargo hold 20.

[0031] In this embodiment, Figure 3As shown, the outer periphery of the slider 4 is coated with a polytetrafluoroethylene layer 6, which reduces the sliding friction between the slider 4 and the slide rail 3, allowing the slider 4 to slide smoothly on the slide rail 3 and be dragged horizontally by manpower or a hoist. Furthermore, the polytetrafluoroethylene coating 6 prevents sparks during sliding and also provides corrosion protection. The polytetrafluoroethylene layer 6 is 3 mm thick. The slider 4 is a stainless steel round block with a diameter of 60 mm and a height of 30 mm, extending vertically.

[0032] In this embodiment, Figure 3 As shown, the slide rail 3 includes a first L-shaped rail 31 and a second L-shaped rail 32. The first L-shaped rail 31 and the second L-shaped rail 32 are spaced relative to each other to form a U-shaped groove with the notch facing upward and an opening at the bottom of the groove. The slider 4 is slidably assembled in the U-shaped groove, and the upper part of the rotating lifting ring 5 is installed on the slider 4 through the opening. The upper parts of the first L-shaped rail 31 and the second L-shaped rail 32 are fixed to the lower surface of the horizontal pipe bracket 2 or the longitudinal pipe bracket 1. The slider 4 is placed in the U-shaped groove. The lower parts of the first L-shaped rail 31 and the second L-shaped rail 32 can provide support for the slider 4 to better ensure the safety of the lifting operation. The first L-shaped rail 31 and the second L-shaped rail 32 can be made of angle iron. The vertical part of the angle iron is 63mm long, the horizontal part is 40mm long, and the thickness is 10mm. Both ends of the U-shaped groove are through-set, and the slider 4 can enter the U-shaped groove from either end of the U-shaped groove, which is convenient for adding or reducing the number of sliders 4 according to the required number of lifting points.

[0033] Furthermore, a stopper 51 is threadedly mounted on the upper portion of the rotating lifting ring 5 and is located below the bottom opening of the U-shaped channel. The stopper 51 can move up and down along the rotating lifting ring 5. When the stopper 51 moves upward, it abuts against the bottom of the U-shaped channel, securing the rotating lifting ring 5 and the slide rail 3. When the stopper 51 moves downward away from the bottom of the U-shaped channel, it unlocks the rotating lifting ring 5 and the slide rail 3, allowing the rotating lifting ring 5 to move along the slide rail 3 with the slider 4. Optionally, the stopper 51 is a nut threadedly mounted on the upper portion of the rotating lifting ring 5.

[0034] In this embodiment, the rotating lifting ring 5 is threadedly connected to the slider 4, which is convenient for assembly and disassembly. When in use, the rotating lifting ring 5 and the slider 4 can be assembled into one piece and assembled into the slide rail 3, or the slider 4 can be assembled first and then the rotating lifting ring 5 is installed on the slider 4. The upper part of the rotating lifting ring 5 is a bolt, and the slider 4 is provided with an internal threaded hole. The bolt is assembled in the internal threaded hole, and the end of the bolt is fixed with a pin, so that the bolt is not easy to rotate in the slider 4.

[0035] In this embodiment, a protective net 7 is mounted on the rotating lifting ring 5 and connected between two adjacent rotating lifting rings 5. The net 7 provides fall protection and isolation, preventing pipeline maintenance personnel from falling from heights. The net 7 also serves as a safety belt anchor point, protecting construction workers 60 when entering the dangerous area of the cargo hold 20. Optionally, a three-proof cloth is also mounted on the rotating lifting ring 5 to provide isolation, preventing welding slag or heavy objects from accidentally falling and damaging the deck or equipment on it.

[0036] During use, the slider 4 equipped with the rotating lifting ring 5 is assembled into the slide rail 3 on the lower surface of the horizontal pipe bracket 2 or the longitudinal pipe bracket 1. According to actual use requirements, a lifting rope 70 is passed through the rotating lifting ring 5 or a lifting hoist is used in conjunction with the rotating lifting ring 5 for various lifting operations, handling operations, etc. Pulling the rotating lifting ring 5 causes the slider 4 to move along the slide rail 3, and the position of the slider 4 is adjusted to make the rotating lifting ring 5 convenient for operation.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
