Abstract

The invention discloses a control method of a continuous bolt lifting system and a bolt lifting platform and belongs to the field of marine machinery. The control method comprises the following steps:determining a lifting command which comprises any one of a spud leg ascending command, a spud leg descending command, a platform ascending command and a platform descending command; judging the current position state of the continuous bolt lifting system, wherein the position state comprises any one of a first position state, a second position state, a third position state and a fourth position state; and controlling the continuous bolt lifting system to act according to the lifting command and the current position state of the continuous bolt lifting system. According to the invention, the reliability of the continuous bolt lifting system is improved.

Description

technical field [0001] The invention belongs to the field of ship machinery, and in particular relates to a control method of a continuous bolt lifting system and a bolt lifting platform. Background technique [0002] Lifting platform is a kind of large-scale marine machinery, which can be divided into rack and pinion lifting platform and pin-type lifting platform according to different lifting methods. The common bolt-type lifting platform mainly includes pile legs, platform and bolt lifting system. The bolt lifting system includes moving ring beam, fixed ring beam, upper bolt, lower bolt and lifting cylinder. Both the moving ring beam and the fixed ring beam are set on the pile legs. And the fixed ring beam is fixed on the platform, the two ends of the lifting cylinder are respectively connected with the moving ring beam and the fixed ring beam, the upper bolt and the lower bolt are respectively installed on the moving ring beam and the fixed ring beam, and the upper bolt ...
