Description
Technical Field
The invention relates to the field of a plane assembly line of a shipyard, in particular to a plane subsection lifting and transporting system.
Background
The plane section production line is an important production facility indispensable for ship production in modern shipyards, and the main operation objects of the plane section production line are parallel midship sections in ship sections, namely, other sections except for a head section, a tail section, a cabin area and an superstructure.
The plane subsection production line generally comprises a plurality of stations, and the general plane subsection production line comprises the following stations: the device comprises a panel alignment welding station, an FCB single-side welding station, a longitudinal rib assembling station, a longitudinal rib welding station, a buffering and transverse moving station longitudinal rib plate assembling station longitudinal rib plate welding station, a pre-fitting-out station and a jacking and transporting-out station.
Technical parameters and producible segment characteristics of a planar segment production line are generally determined in a planning and designing stage, and generally, the planar segment production line generally determines a maximum segment size and a maximum segment weight, but research on a minimum on-line segment size is very little.
Generally speaking, the minimum section capable of being fed on the production line is mainly determined by the center distance of the hydraulic jacking devices of the plane section production line, and the section smaller than the center distance of the hydraulic jacking devices cannot be used. Therefore, in the construction planning period of many shipyards in China at present, due to the fact that the center distance of the hydraulic jacking devices is large, due to the fact that many small and medium-sized ships are limited by the structural characteristics of the ship body, the sectional division is small, and online production cannot be achieved. According to statistics of domestic parts of shipyards, the proportion of the plane sections which cannot be jacked out due to small section sizes is between 10 and 20 percent of all the plane sections at present.
Taking a certain plane subsection production line as an example, the center distance of the subsection carrying trolley is 8.6m, the center distance of the hydraulic carrying trolley is 11m, and a subsection scale space of about 2.4m is arranged in the middle. Because the highest jacking of the sectional carrying trolley can only be 0.5m, the requirement of the sectional carrying flat car on the conveying height can not be met. Therefore, segments between 8.6m and 11.0m cannot generally be produced in-line. According to statistics, the proportion of the plane sections between 8.6m and 11.0m in ships with the load of less than 10 ten thousand and the weight of the ships with the load of less than 10 ten thousand is about 15 percent, and because the sections cannot be produced on a production line, the sections are mainly manufactured manually at present, so that the manufacturing cost and time of the sections are increased, and the capacity waste of the plane section production line is also caused indirectly.
However, if a dedicated pipeline is disposed for such a small planar segment, the cost is too high, and the offset occurs due to too large area when a large planar segment pipeline is operated. Therefore, a plane segmentation assembly line suitable for various plane segments is urgently needed in the industry.
