Flexible limit boarding ladder

Abstract

The invention discloses a flexible limit boarding ladder which comprises a ship limit sliding groove, a ship sliding base, a ship flexible air cylinder, the boarding ladder, a dock limit sliding groove, a dock sliding base and a dock flexible air cylinder, wherein the ship limit sliding groove is fixed in a ship, a pulley is arranged on the bottom part of the ship sliding base and moves front and back inside the ship limit sliding groove, the ship flexible air cylinder is arranged inside the ship sliding base, the ship flexible air cylinder comprises a first piston rod which is connected with one end of the boarding ladder, the dock limit sliding groove is fixed in a dock, the pulley is arranged on the bottom part of the dock sliding base, the dock flexible air cylinder is arranged inside the dock sliding base, and the dock flexible air cylinder comprises a second piston rod which is connected with the other end of the boarding ladder. The flexible limit boarding ladder can convert a pulling force when the ship jolts into a front and back force through the air cylinder and a spring, uses the front and back movement and the timely buffering of the sliding base in the limit sliding groove and guarantees the stability of the boarding ladder, and the flexible limit boarding ladder has a lighting function.

Description

technical field [0001] The invention relates to a ship accessory, in particular to a retractable position-limiting boarding ladder. Background technique [0002] After the ship docks, passengers must rely on boarding ladders to get on and off the ship, load or unload goods. After small ships dock, people often use a piece of wood to frame between the ship and the wharf to form a simple boarding ladder. Passengers, but the hull shakes irregularly under the push of wind and waves, such a simple boarding ladder is prone to the danger of falling. [0003] On large ships, boarding ladders are specially equipped. The boarding ladders are made of metal and are erected between the ship and the wharf. Although they are very strong, the pulling force on the boarding ladders is relatively large when the ship shakes. The boarding ladder needs to bear the force of the whole ship, it will be damaged quickly, and the replacement cost is high. Contents of the invention [0004] The purp...

[0003] On large ships, boarding ladders are specially equipped. The boarding ladders are made of metal and are erected between the ship and the wharf. Although they are very firm, the pulling force on the boarding ladders is relatively large when the ship shakes. The boarding ladder needs to withstand the force of the whole ship, it will be damaged quickly, and the replacement cost is high
