Abstract

The invention provides a mast and a ship, and relates to the technical field of vehicles. The mast comprises a first mast and a second mast; the first mast is arranged on a ship; a first sliding rail is arranged on the first mast, and the first sliding rail extends in the axis direction of the first mast; the second mast is arranged on the first sliding rail and can slide on the first sliding rail. In order to facilitate description, the first mast comprises a first end and a second end, the first end is the end, connected with the ship, of the first mast, and the second end is the end, away from the ship, of the first mast. The second mast is arranged on the first sliding rail and can slide on the first sliding rail, when the ship normally travels, the second mast slides to the second end, at the moment, the height of the mast is the maximum, and when the ship sails and encounters a height-limited channel such as a bridge, the second mast starts to slide on the first sliding rail towards the first end. The height of the mast is contracted so that the ship can walk together conveniently.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a mast and a ship. Background technique [0002] The mast refers to the tall column on the ship that hangs the sails and flags, installs the antenna, and supports the observation platform. It is usually erected vertically from the keel or the middle plate of the ship, and can support the girder sail, the boom, or the girder. The mast is usually used to install signal lights, hang flags, set up telegraph antennas, etc., or to support cargo poles, hoist and unload goods, etc. For some super-large ships, when passing through some height-restricted channels, due to their high masts, they often become obstacles to their peers. [0003] In the prior art, in order to allow the ship to normally pass through the channel with limited height, it is usually made into a dumpable mast. However, when the dumping mast falls down, it is easy to accidentally injure the crew, and because the heig...
