Description
Technical Field
The invention relates to the field of a plane assembly line of a shipyard, in particular to a plane segmentation assembly line.
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.

Detailed Description
The planar subsection production line comprises a subsection lifting beam and a jacking device;
as shown in fig. 1, the jacking devices are arranged at two sides of the working area of the assembly line in pairs (the distance between the jacking devices in the horizontal direction is smaller than the distance between the jacking devices in the vertical direction, so that the jacking operation of large, medium and small segmental planes on the assembly line can be realized);
the sectional lifting beams are used in pairs in the operation process;
in the operation process, the sectional lifting beam is lifted and carried to the position of a production line working area by equipment with a lifting function, so that the sectional lifting beam is arranged in the production line working area in a crossing manner, and two end parts of the sectional lifting beam are erected at the tops of a pair of oppositely arranged jacking devices;
thus, a working area enclosed by the sectional lifting beam and the jacking device is realized, and the working area is slightly narrow in the horizontal direction and slightly wide in the vertical direction.
When the segment lifting beam is erected on the jacking device, the initial state is as shown in fig. 2, the lifting function part is positioned below the planar segment, and when the jacking device is started to move upwards, the lifting beam can move upwards under the driving of the jacking device. Therefore, the sectional plane erected on the lifting device is also driven upwards, and finally the lifting device is lifted to the position shown in the figure 3 and transported out by other equipment.
As regards the lifting beam, it may be any structure having a certain length and erection function.
In this embodiment, a segmented lifting beam is provided which accomplishes this function and is constructed in detail as shown in figures 4-7.
As shown in fig. 4 to 5, the lifting beam provided by the present embodiment is composed of a lifting beam main body and other functional members;

also, in order to achieve structural reinforcement of the extension, a girder lower rib 9 is also arranged in the downward extension of the extension.
In addition, the width of the lifting function member 1-2 is larger than that of the main body part of the lifting beam, and the extension parts towards the two sides form convex wing structures at the two sides of the middle section of the main body of the lifting beam.
The wing-like structure is provided with a plurality of lifting supports 6;
the lifting support 6 is arranged uniformly on the wing-like structure.
The lifting support comprises a support web 6-1, a support panel 6-2 and a support toggle plate 6-3, wherein the support web 6-1 and the support toggle plate 6-3 form a cross-like shape to support the support panel 6-2.
