Abstract

The invention relates to the technical field of underwater vehicle mast lifting, and discloses a mast lifting guide device which is used for conducting lifting guide on a mast on an underwater vehicle cabin and comprises a hydraulic driving assembly, a stroke detection switch, a fixed guide assembly and a lifting supporting assembly. The two are arranged in the cabin of the underwater vehicle; the lifting supporting assembly is arranged on the inner side of the fixed guiding assembly and connected with the mast. The hydraulic driving assembly provides power, drives the lifting supporting assembly to do lifting motion and drives the mast to rise and retract. The fixed guide assembly plays a role in guiding and circumferential rotation prevention in the lifting motion of the lifting supporting assembly. And after the mast is retracted in place, the stroke detection switch outputs a retraction in-place signal. The device has the capacity of vertical lifting guiding and circumferential anti-rotation limiting, the overall structure is simple, and functions are easy to achieve.

Description

technical field

[0001] The invention relates to the technical field of underwater vehicle mast lifting, and more specifically, relates to a mast lifting guide device. Background technique

[0002] Underwater unmanned submersibles perform specific tasks such as communication and reconnaissance on the water surface, which often need to be completed by configuring relevant functional masts and raising them above the water surface. This mast is realized by a special lifting device. Because the lifting device and the mast are cantilever structures after they are raised, they are greatly affected by the impact of waves and the resistance of water navigation. Therefore, the mast lifting device should have a certain strength and rigidity, and it also needs certain support and guidance during movement. resist the above effects. At present, the mast lifting device is generally a flip lifting type and a vertical lifting type.

[0003] The turning and lifting device is generally reali...
