Electric collapsible mast device and ship applying same

Abstract

The invention concretely discloses an electric collapsible mast device and a ship the applying same. The electric collapsible mast device comprises a mast part, a motor, a first limiter, a second limiter, a transmission mechanism and a controller, the controller is electrically connected with the motor, the mast part comprises an upper mast and a lower mast, the upper mast is rotatably connected with the lower mast through a shaft rod at the top end of the lower mast, the transmission mechanism comprises a first fixed pulley arranged on the lower mast, a second fixed pulley arranged on the shaft rod, a third fixed pulley arranged on the upper mast and a transmission rope, the motor is sequentially connected with the first fixed pulley, the second fixed pulley and the third fixed pulley through the transmission rope, the first limiter is arranged in the middle or at the bottom end of the lower mast and is parallel to the vertical upper mast, and the second limiter is arranged at the top end of the lower mast and is parallel to the inverted upper mast, so that the ship mast is more convenient and labor-saving to fold, and the problem that the ship mast is difficult to fold is avoided.

Description

technical field [0001] The invention relates to the field of ships and ship masts, in particular to an electric reversible mast device and a ship using the same. Background technique [0002] With the progress of society and the development of major cities, more and more bridges will be built on the rivers crossing the big cities. Only the bridges built on the rivers of the main channel will consider the passage of ships. The design navigable height is about 35 meters, but the bridges built on the branch rivers will not consider the navigable height, the general navigable height is about 13 meters; but with the advancement of battery technology and the development of tourism, small aluminum alloy passenger boats or sightseeing boats in urban branch rivers are booming. Mainly ships below 40 meters. Due to the height requirements of the mast, such ships are often unable to pass the bridges on the branch rivers of the city. The potential safety hazard caused by the crew needin...

Mainly ships below 40 meters. Due to the height requirements of the mast, such ships are often unable to pass the bridges on the branch rivers of the city. The safety hazard caused by the crew needing to go up to the top deck and lower the mast increases the difficulty of operation
