Three-freedom-degree hydraulic drive heavy load stabilizing platform

Abstract

The invention aims at providing a three-freedom-degree hydraulic drive heavy load stabilizing platform, which consists of parts including a transverse rocking mechanism, a transmission mechanism, a longitudinal rocking mechanism, a transverse rocking servo drive executing mechanism, a yawing mechanism, a base, a yawing servo drive executing mechanism, a longitudinal rocking servo drive executing mechanism, a hydraulic support shock absorption mechanism, a stabilizing platform deck and the like. An optical fiber gyro is used as an inertia measurement device for measuring transverse rocking, longitudinal rocking and yawing information of a carrier, so that the transverse rocking servo drive executing mechanism, the longitudinal rocking servo drive executing mechanism and the yawing servo drive executing mechanism are controlled; and the compensation on the disturbance received by the stabilizing platform in the transverse rocking, longitudinal rocking and yawing directions is realized, so that the stabilizing platform deck is always in a horizontal stable state. The three-freedom-degree hydraulic drive heavy load stabilizing platform has the advantages that the compensation on the interference received by a boat in the transverse rocking, longitudinal rocking and vertical swinging directions is realized, and the relatively still state is always maintained.

Description

technical field [0001] The invention relates to a heavy-load stable platform, specifically a heavy-load stable platform for ships. Background technique [0002] Because ships sailing on the sea are inevitably affected by harsh environments such as wind, waves, currents, and tides, resulting in disturbances in the directions of roll, pitch, and yaw, which will not only affect the normal production operations of the ship, but also directly Threats to the safety of production systems, equipment and personnel. For example, the ship-borne helicopter platform, due to the large-scale swing and heave movement of the ship when it is disturbed by the wind and waves, brings great difficulties and risks to the helicopter's take-off and landing; The lifting and heaving of the cargo makes it extremely difficult to control the lifting and landing of the cargo, and is prone to collisions; in deep sea mining, due to the deep movement of the mining ship, it is very easy to cause the fatigue ...

Problems solved by technology

[0002] Because ships sailing on the sea are inevitably affected by harsh environments such as wind, waves, currents, and tides, resulting in disturbances in the directions of roll, pitch, and yaw, which will not only affect the normal production operations of the ship, but also directly Threats to the safety of production systems, equipment and personnel

For example, the ship-borne helicopter platform, due to the large-scale swing and heave movement of the ship when it is disturbed by the wind and waves, brings great difficulties and risks to the helicopter's take-off and landing; The lifting and heaving of the cargo makes it extremely difficult to control the lifting and landing of the cargo, and is prone to collisions; in deep sea mining, due to the deep movement of the mining ship, it is very easy to cause the fatigue fracture of the mining pipe; in addition, the laying of submarine cables and pipelines has different degrees affected by the wave motion of the workboat on the sea surface

At present, many working ships at sea already have a dynamic positioning system, which compensates the ship to a certain extent in the direction of sway and surge, but it does not affect the roll, pitch and vertical heave of the ship. difficult to compensate

Although the three-degree-of-freedom self-stabilizing platform described in Chinese patent CN203686509U can realize compensation for disturbances in the directions of roll, pitch and yaw, due to the use of a traditional frame structure, the load capacity is small; A ship-borne heavy-duty stable platform, although the mechanical structure has been improved, but it has not broken away from the frame structure, and the load capacity is only 250 kg
