A coupling for a ship's anti-climbing railing

Abstract

The invention relates to a coupler of a marine anti-climbing handrail. The coupler comprises a long shaft with a one-sided flange disc, and a fixing sleeve which is in rolling fit with the long shaft through a rolling piece. The fixing sleeve transversely penetrates through a baluster of the marine anti-climbing handrail and is connected with the baluster in a fastened mode. The fixing sleeve can be radially inserted into a concave pit in the long shaft through a detachable bolt on the fixing sleeve. The head of the bolt is fixedly provided with a friction piece for increasing friction damping. A transverse pin hole is formed in the bolt. A pin is inserted into the pin hole, and the pin and the fixing sleeve are fixed in a clamped mode at the corresponding position for limiting the position of the bolt. The end, with no flange disc, of the long shaft is sleeved with a coupling flange for being axially and fixedly connected with an anti-climbing transverse rod. The coupling flange and the long shaft are provided with at least one pair of threaded holes for connection in the radial direction. The coupling flange and the long shaft are fixed through the threaded holes and bolts. The transverse rod of the anti-climbing handrail can be distributed and installed, the whole transverse rod does not need to be disassembled completely during maintenance, the transverse rod disassembling frequency is lowered, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to a coupling for a ship's anti-climbing railing, which belongs to the technical field of ship safety devices. Background technique [0002] At present, pirates generally grab the structure on the ship by flying claws, then grab the ropes under the flying claws, step on the hull plate, and use hands and feet to climb onto the ship. Currently, most pirate ships are detected with the help of radar and searchlights. Especially at night, when pirate ships enter the blind spot of radar or light irradiation, it is difficult for the crew to find pirates. When the pirate's flying claw hits the ship's structure, because the pirates have guns, it is difficult for the crew to get close to the flying claw to cut the rope, but they are forced to hide in the anti-piracy safe cabin to wait for external rescue. [0003] This difficult problem has not been solved, and some countermeasures have also appeared in the prior art. For example, the Chi...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: the existing railings on the side of the ship are used to prevent climbing, and the disassembly and maintenance are labor-intensive; the length of the crossbar is long, and the coaxiality control is difficult, resulting in the need for multiple system units , resulting in a complex structure; when the ship is docked, it is necessary to fix the gangway on the side rail, because the rail will rotate, it is difficult to fix it with the gangway, which affects the crew's disembarkation; when the ship docks, it is necessary to use the outermost rail When the bar is used as a fixed pulley to convey items, the rotation damping of the cross bar rotation is too small and cannot be adjusted, which makes it unable to adapt to the function of the fixed pulley
