Abstract

The invention discloses a mast lifting device, and aims at providing a mast lifting device which is simple in structure, low in manufacturing cost, and safe and convenient to operate. The mast lifting device comprises a pedestal (1), a mast base (2) and a mast (3), wherein a screw base (4) is further fixedly arranged on the pedestal (1); a movable pillar (5) and a screw (6) are arranged on the screw base (4); a transmission device connected with the screw (6) in a transmission manner is arranged on the screw (6); a lifting base (7) is fixedly arranged on the mast (3); a movable pillar (8) rotationally connected with the lifting base (7) is arranged on the lifting base (7); the screw (6) is in threaded connection with the movable pillar (8); and rotation directions of the movable pillar (5) and the movable pillar (8) are the same as that of the mast (3) around the mast base (2). The mast lifting device is applied to the technical field of lifting masts.

Description

technical field [0001] The invention relates to a lifting device, in particular to a mast lifting device. Background technique [0002] The mast is a bracket for installing antennas, navigation lights and communication facilities on the ship. It is a very important safety facility when the ship is sailing. Its structure usually has single-column pole type, tower type, hoarding type and other forms. The mast is generally installed on the center line of the highest roof of the ship, and its height is mostly more than 3.5 meters. With the development of society, more and more bridges are erected on the ship's channel. When the ship passes under the bridge, if the mast on the ship collides with the bridge, the height of the mast needs to be lowered to ensure that the ship can pass smoothly. After the ship passes through the bottom of the bridge, the mast must be erected immediately, so as to ensure the safety of the ship's navigation. At present, the mast is usually put down ...
