Problems solved by technology

[0002] Now there are many offshore platform cranes in case of emergency (power outage or crane failure), unable to lower the materials hovering in mid-air to the wind turbine tower platform or transport ship in time, and can only wait for the power supply to recover or troubleshoot The crane can only be operated after the material is suspended in mid-air for a long time, there is an uncontrollable danger, such as the material swinging with the wind may cause damage to the material or the tower

Abstract

The invention relates to the field of cranes, and provides an offshore platform crane, a control method thereof and an offshore platform. The crane comprises a cantilever crane; the winding device is mounted on the arm support, and the winding device comprises a winding drum, a driving part, a centrifugal speed limiter and a limiting piece; the driving part comprises a driving motor and a brake, the winding drum is in transmission connection with the driving motor, the centrifugal speed limiter is in transmission connection with the winding drum, and the limiting part can move relative to the centrifugal speed limiter so as to be switched between a limiting state and an idle state; and in the idle state, the limiting piece is separated from the centrifugal speed limiter, then braking of the brake to the driving motor is released, so that the material descends under the action of the gravity of the material, and when the descending speed of the material reaches a set speed, the centrifugal speed limiter controls the winding drum to decelerate. According to the crane provided by the invention, through a matching structure of the centrifugal speed limiter and the limiting piece, materials can safely and stably fall in case of emergency.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to an offshore platform crane and a control method thereof and an offshore platform. Background technique [0002] There are many offshore platform cranes in emergency situations (power failure or crane failure), unable to drop the materials hovering in mid-air to the wind turbine tower platform or transport ship in time, and can only wait for the power supply to recover or troubleshoot The crane can only be operated after the material is suspended in mid-air for a long time, and there is an uncontrollable danger. For example, the material swinging with the wind may cause damage to the material or the tower. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an offshore platform crane. Through the cooperation structure of the centrifugal speed limiter an...
