Description

Technical Field

[0001] The utility model relates to the technical field of ship equipment, in particular to a handrail for an LNG ship dock. Background Art

[0002] Liquefied natural gas ship, referred to as "LNG ship", is a liquid cargo ship designed to transport liquefied natural gas (LNG). LNG ships can be divided into independent tank type and membrane type according to the structure of the liquid cargo tank. The former is to place cylindrical, tank-shaped, spherical and other shaped tanks inside the ship; the latter adopts a double hull structure, and the inner hull is the load-bearing shell of the liquid cargo tank. Compared with the independent type, the advantage of the membrane type is high volume utilization and light structural weight. Therefore, newly built liquefied natural gas ships, especially large ones, mostly use membrane structures. LNG ships have complex equipment, high technical requirements and high construction costs.

[0003] Conventional ships use aluminum gangways to lower to the dock to board and disembark crew members. In a typical LNG ship dock, the middle of the cargo hold is set up as a loading / unloading area for loading and unloading LNG. Due to the unique dock type, it is impossible to set up a gangway in the middle of the cargo hold, so only alternative handrails can be selected. The types of handrails required for LNG ships to berth at the dock and sail at sea are also different. The general handrail structure cannot meet the needs, so a handrail dedicated to LNG ships is needed. Utility Model Content

[0004] Based on the above-mentioned problems existing in the prior art, the purpose of the embodiments of the present application is to provide a railing for an LNG ship dock, comprising a heavy railing, a connecting sleeve and a detachable railing, wherein the detachable railing is installed on the heavy railing through a connecting sleeve, thereby meeting the requirements for the detachable railing under different working conditions and improving the applicability.

[0005] Furthermore, the connecting sleeve includes a hollow sleeve on the upper side, a base on the lower side, and a latch with a tongue, wherein the upper end of the hollow sleeve is open, the base is fixed to the bottom of the hollow sleeve, and the latch with a tongue is connected to the base.

[0006] Furthermore, the connection method between the tongue-shaped latch and the base is preferably, but not limited to, a soft steel wire rope connection.

[0007] Furthermore, the hollow sleeve is provided with a through hole for the tongue-shaped latch to pass through.

[0008] Furthermore, the detachable handrail includes a handrail and two support rods 1, wherein the two support rods 1 are respectively fixed at two ends of the same side of the handrail.

[0009] Furthermore, the support rod is also provided with a through hole for the tongue-jointed latch to pass through.

[0010] Furthermore, the heavy-duty railing includes a square tube and two support rods, wherein one end of a plurality of the two support rods is vertically fixed at intervals on the bottom of the square tube, and another two support rods are connected between adjacent two support rods.

[0011] Furthermore, the square tube is provided with mounting holes for mounting the detachable railings.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are: solving the railing requirements for boarding an LNG ship at a berthing terminal; solving the railing switching under two working conditions: the working condition of berthing at a berthing terminal and the working condition of sailing at sea.
