Description

TECHNICAL FIELD

[0001] The present application relates to the field of LNG liquefied natural gas ship construction technology, in particular to a cable entry device of an LNG ship hose crane. BACKGROUND

[0002] The Qatar 174,000 cubic meter LNG liquefied natural gas ship manifold area adopts a 10T-23M (10-ton load, 23-meter length of boom) cargo oil hose crane, which can be used for lifting oil pipes, cargoes, supplies and other miscellaneous items, and can also be used for personnel lifting under certain working conditions.

[0003] The hose crane cylinder is located on the cargo hold dome deck structure, and due to the heavy weight of the crane, the reverse side of the structure must be reinforced with a cylinder structure and a reinforcing rib plate. In the past, the crane outlet penetrates the bottom of the crane cylinder, and the cable is blocked after coming out by the reinforced cylinder structure and the reinforcing rib plate, which is not convenient for construction.

[0004] Due to the longitudinal and transverse intersection of the reinforcing rib plate inside the reverse side of the reinforced cylinder, the cable maintenance and maintenance in the later stage are also not convenient. CONTENT OF THE UTILITY MODEL

[0005] In order to avoid the interference with the reverse side reinforcing structure at the bottom of the cylinder, which leads to the inconvenience of cable laying construction, the present application provides a cable entry device of an LNG ship hose crane.

[0006] The present application provides a cable entry device of an LNG ship hose crane, which adopts the following technical scheme:

[0007] A cable entry device of an LNG ship hose crane, comprising a cargo hold dome deck, a hose crane cylinder is fixedly connected to the cargo hold dome deck, a wire inlet pipe is fixedly connected to the side wall of the hose crane cylinder, one end of the wire inlet pipe is in communication with the side wall of the cargo hold dome deck, and the other end of the wire inlet pipe is in communication with the hose crane cylinder.

[0008] Optionally, the wire inlet pipe comprises straight pipe sections at both ends, a bend pipe section is arranged between the two opposite straight pipe sections, and the straight pipe sections are in communication with the bend pipe section.

[0009] Optionally, the straight pipe sections and the bend pipe section are detachably connected through connecting flanges.

[0010] Optionally, the bend pipe section is of an arc structure.

[0011] Optionally, the straight pipe sections and the bend pipe section are both of stainless steel material.

[0012] Optionally, the straight pipe section near the side of the hose crane cylinder extends into the inside of the hose crane cylinder, and the straight pipe section near the side of the cargo hold dome deck extends into the inside of the cargo hold dome deck.

[0013] Optionally, the axis of the straight pipe section near one side of the hose hoist cylinder is arranged along the radial direction of the hose hoist cylinder.

[0014] Optionally, the axis of the straight pipe section near one side of the hose hoist cylinder is perpendicular to the axis of the hose hoist cylinder, and the axis of the straight pipe section near one side of the cargo hold dome deck is perpendicular to the cargo hold dome deck.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The hose hoist cylinder inlet pipe is positioned on the outer side of the hose hoist cylinder, so as not to interfere with the reverse reinforcement structure at the bottom of the cylinder, so that the construction does not need to be carried out between the reverse reinforcement structure ribs on the cylinder, facilitating construction, and facilitating later cable maintenance and maintenance.

[0017] 2. The hose hoist cylinder inlet pipe adopts a stainless steel round straight pipe connected and fixed by stainless steel flanges and stainless steel elbow pipes at both ends, thereby forming a complete closed-loop detachable inlet pipe, which can not only prevent mechanical damage to the cable and prolong the service life of the cable, but also facilitate later cable maintenance and maintenance.

[0021] The Qatar 174,000 cubic meter LNG liquefied natural gas ship manifold area adopts a 10T-23M (10-ton load, 23-meter length of boom) cargo oil hose hoist, which can be used to lift oil pipes, cargo, supplies and other miscellaneous items, and can also be used for personnel lifting under certain working conditions.

[0022] The hose hoist cylinder is located on the cargo hold dome deck structure, and due to the heavy weight of the hoist, the reverse structure must be reinforced with a cylinder structure and a reinforcing rib. In the past, the hoist outlet penetrates the bottom of the hoist cylinder, and the cable is blocked by the reinforced cylinder structure and the reinforcing rib after it comes out, which is not convenient for construction.

[0023] Because the reinforcing ribs inside the reinforced cylinder on the reverse side of the structure are crisscrossed, it is also inconvenient for later cable inspection and maintenance.

[0024] To avoid interference with the reinforced structure on the reverse side of the bottom of the cylinder, which would make cable laying inconvenient, this application provides a cable entry device for an LNG ship hose crane.

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0028] This application discloses a cable entry device for a flexible hose gantry crane on an LNG ship. (Refer to...) Figure 1 , Figure 2 A cable entry device for a flexible hose gantry crane for an LNG carrier includes a horizontally arranged cargo hold dome deck 1, and a flexible hose gantry 2 is vertically arranged on the top wall of the cargo hold dome deck 1. The flexible hose gantry 2 is fixedly connected to the cargo hold dome deck 1 and is arranged perpendicularly to the cargo hold dome deck 1.

[0029] An inlet pipe 3 is provided on the outside of the flexible hose gantry 2. One end of the inlet pipe 3 is fixedly connected to the side wall of the flexible hose gantry 2, and the other end of the inlet pipe 3 is fixedly connected to the side wall of the cargo hold dome deck 1.
