Description
Technical Field
The invention relates to the field of shipyard plane assembly lines, in particular to a plane sectional lifting and transporting system.
Background
The plane segmentation assembly line is an important production facility which is indispensable to the production of ships by modern shipyards, and the main operation object is to segment parallel midship bodies in ship segments, namely, to remove the head, tail, cabin area and other segments after superstructure.
The planar segmentation assembly line generally comprises a plurality of stations, and the stations included in the planar segmentation assembly line generally include: the device comprises a jointed board positioning welding station, an FCB single-sided welding station, a longitudinal rib assembling station, a longitudinal rib welding station, a buffering and transverse moving station, a longitudinal rib plate assembling station, a pre-outfitting station and a jacking and conveying-out station.
Technical parameters of the planar segmentation pipeline and producible segmentation characteristics are generally determined in a planning and design stage, and generally, the planar segmentation pipeline generally determines the maximum segmentation size and the maximum segmentation weight, but little research is conducted on the minimum online segmentation size.
In general, the minimum section capable of being on line is mainly determined by the center distance of the hydraulic jacking devices of the planar section assembly line, and the section smaller than the center distance of the hydraulic jacking devices is mainly used for hoisting components due to the fact that the jacking devices cannot be used, and the crane usually configured in the planar section assembly line workshop is small in rated load and cannot hoist the sections. Therefore, at present, in the period of construction planning of many shipyards in China, the equipped planar segmentation assembly line is small in segmentation division and can not be produced on line due to the fact that the center distance of the hydraulic jacking device is large and many small and medium-sized ships are limited by the structural characteristics of the ship body. According to statistics of domestic part shipyards, the proportion of the planar sections which cannot be lifted up and transported out due to small section size is between 10 and 20 percent in all the current planar sections.
Taking a certain plane segmentation assembly line as an example, the center distance of the segmentation transport trolley is 8.6m, the center distance of the hydraulic transport trolley is 11m, and a segmentation scale space of about 2.4m is arranged in the middle. As the sectional conveying trolley can only be lifted to 0.5m at the highest, the conveying height requirement of the sectional conveying trolley can not be met. Thus, segments between 8.6m-11.0m are typically not pipelining. According to statistics, in ships with 10 ten thousand weight tons or less, the planar segmentation proportion between 8.6m and 11.0m is about 15 percent, and because the segmentation can not be produced in a pipeline, the manual manufacturing is mainly adopted at present, the segmentation manufacturing cost and time are increased, and meanwhile, the productivity waste of the planar segmentation pipeline is indirectly caused.
However, if a dedicated pipeline is arranged for such small planar segments, the cost is too high, and problems such as offset due to too large area occur in the large planar segment pipeline operation are caused. Therefore, a planar segment pipeline which can be applied to various planar segments is urgently needed in the industry.
