Description

Technical Field

[0001] The utility model relates to the technical field of ship masts, in particular to an electric reversible assembled mast. Background Art

[0002] The ship mast is a device for installing navigation, communication and signal equipment, mainly including radar mast, signal mast (fore and aft mast), light rack (sidelight rack, taillight rack, etc.), various signal light poles (such as the Suez Canal signal light pole), etc. Due to the large number of bridges in the waterway, the height of inland ships above the waterline is limited. For example, the height limit for secondary waterways is 7m, but the net height of the ship cabin is also required, which shall not be less than 1.9m, which means that the height of the main hull and superstructure above the waterline cannot be reduced too much.

[0003] At present, most of the masts of inland vessels are made by shipyards. The masts of each ship are mostly different. The production efficiency of masts is low, the production cost is high, the convenience of installation and use varies, and the safety and reliability need to be tested. When a ship passes through a height-restricted area, several crew members are usually required to stand on the canopy deck where the mast is located at the same time to carry out the mast inversion and recovery operations. Since the canopy deck is located at the highest point of the ship and is an open-air deck, coupled with the swaying caused by wind and waves during the voyage of the ship, the crew members have greater safety risks during the operation and may fall.
