One preferred scheme is that a mast inverting support rod is arranged on one side of the deck where the rod body is placed, and a support part matched with the side face of the rod body is arranged at the top of the mast inverting support rod.

According to the scheme, the mast body is used for supporting the laid mast body.

One preferable scheme is that a vertical mast limiting rod is fixedly arranged on the deck, and the vertical mast limiting rod is in limiting fit with one side, back to the falling direction, of the mast body when the mast body is erected.

According to the scheme, the vertical mast limiting rod is used for limiting the rod body when the rod body is erected, so that the rod body is kept in a vertical state under the limiting effect when the rod body is erected.

Preferably, the speed-adjustable electric reversible mast further comprises proximity switches respectively arranged at the extreme positions when the rod body is laid down and raised, and the proximity switches are electrically connected with a control circuit of the motor.

According to the scheme, when the rod body is laid down and erected to reach the limit position, the proximity switch is triggered, the control circuit is automatically switched off, and the rod body stops moving.

Preferably, the speed-adjustable electric reversible mast further comprises a support arranged on the deck, and a chain guide roller is arranged on the support and is positioned on a movement path of the steel wire rope.

According to the scheme, the chain guide roller is used for bundling and guiding the steel wire rope, so that the steel wire rope is prevented from interfering with other devices on the ship.

Preferably, the proximity switch is a normally closed switch.

According to the scheme, the proximity switch is normally in a conducting state and is automatically switched off when being triggered, so that the rod body stops moving.
