This paper discloses a leg overhaul device for a jack-up drilling platform, comprising: a working basket assembly, which is arranged around the leg structure, and is used to load overhauling tools and maintenance personnel; a driving mechanism, which is fixed On the work basket assembly, the output end of the drive mechanism is engaged with the rack of the leg to drive the work basket assembly to move up and down along the leg; the control mechanism is fixed on On the work basket assembly, the control mechanism is electrically connected to the drive mechanism for controlling the drive mechanism. This article relates to the field of drilling, and provides a leg inspection device for jack-up drilling platforms, which can overcome the labor-intensive problem of setting up the working frame. It can carry maintenance tools, materials and maintenance personnel to move up and down along the pile legs, eliminating Set up a work frame to save manpower and improve work efficiency significantly.
Description
technical field [0001] The invention relates to the field of drilling, in particular to a leg inspection device for a self-elevating drilling platform. Background technique [0002] The legs of the jack-up drilling platform are an important part of the platform structure. At present, due to the regular inspection, temporary maintenance and repair of the pile legs, the auxiliary work involved in erecting the work frame is huge. Basically, the corresponding work is carried out in the traditional mode of manual construction of the work frame. Due to the relatively long pile legs, the erection will be limited. Human resources for work racks and material resources for work racks. [0003] At present, there are more than 500 jack-up drilling platforms in the world, and most of the leg structures are independent three-pile truss rack structures. According to the requirements of classification societies, the platform shall undergo annual inspection every year, intermediate inspect...
