Anti-overturn moving and real-time locking device for ocean platform cantilever beam

Abstract

The invention discloses an anti-overturn moving and real-time locking device for an ocean platform cantilever beam. The anti-overturn moving and real-time locking device for the ocean platform cantilever beam is formed by an ocean drilling unit, a cantilever moving beam, a pushing oil cylinder, a front base, a rear base, a fixing hinge pin and a deck. Main connection modes of the parts include that one end of the pushing oil cylinder is mounted on the deck through the front base, and the other end of the pushing oil cylinder is connected with a pushing block through the fixing hinge pin. By the coordinative effect of a real-time locking mechanism and a positioning mechanism, it is guaranteed that a pin is in an insertion reliable protection state constantly during alternation of plugging and unplugging of pins, and heavy economic losses of lives and properties caused by marine high-risk operations performed under the work condition without protection in the single direction during moving of the cantilever beam are prevented. The device is easy to operate, safe and reliable and capable of being used for moving protection of ocean platform drill floors and improvement of the safe protection technology of land moving devices of different sizes and has quite high industrialization popularization and application value.

Description

technical field [0001] The patent of the present invention relates to an anti-overturning movement and real-time locking device of a cantilever beam of an offshore platform, which belongs to the field of machinery. Background technique [0002] Mobile devices range from small elevators to large ocean engineering platform equipment. The reliability of their technology involves the safety protection of life and major equipment. The elevator reproduced the "eating" accident, and a 21-year-old girl was crushed to death by the elevator. On September 7, 2010, an offshore platform in Shengli Oilfield suffered a tilting accident during offshore operations, causing 36 people to be in danger, 2 people drowned and died, and the entire offshore platform was scrapped, causing major economic losses. During the operation of the “Kan Tan No. 2” jack-up drilling platform insured by the People’s Insurance Company of China, one pile leg sank due to the subsidence of the ground during operatio...

Problems solved by technology

On September 7, 2010, an offshore platform in Shengli Oilfield suffered a tilt accident during offshore operations, resulting in 36 people being in danger, 2 people drowning and death, and the entire offshore platform was scrapped, causing major economic losses

During the operation of the "Kan Tan No. 2" jack-up drilling platform insured by the People's Insurance Company of China, one pile leg sank due to the subsidence of the ground during operation, causing the platform to tilt, resulting in huge salvage and repair costs

[0003] The cantilever beam moving device of the offshore platform involved in the patent of the present invention is used to move the cantilever beam carrying large-scale offshore drilling equipment. At present, the alternate movement mode of the plug-in pin and the push mode of the ratchet are adopted, and there is a single di
