The invention relates to shipbuilding, in particular to installations for the manufacture of hull structures.

The purpose of the invention is to increase productivity.

Figure 1 shows an installation for the manufacture of hull structures, a general view; figure 2 - section aa in figure 1; on fig.Z - view B in figure 1; on figa - section bb In figure 1; on fig.Z - floor shop; in fig. 6 is a view of FIG. 3; figure 7 - installation of a replaceable working body (traverse) on the lifting device; on fig.Z - type D figure 7; Fig, 9 - installation of a replaceable working body (welding carriage with semiautomatic devices) on a lifting device; in FIG. 10, view E in FIG. 9; FIG. 11. - installation of a replaceable member (set orientation device) on a lifting device; Fig. 12 is a view of Fig. 11; on Fig - installation of the replaceable working body (device for pressing the set beams to the panel) on the lifting device; FIG. 14 is a view; and FIG. 13; Fig 15 - installation of a replaceable working body (welding tractor) on a lifting device; in Fig.16 is a view of K in Fig. 15.

The installation consists of a self-propelled portal 1 containing span beams 2 and pillars 3. On beams 2 a carriage 4 is installed with a vertical telescopic column 5 and a telescopic guide 6, at the bottom end of which a column rotation drive 7 is fixed, connected to a lifting body 8 equipped with grippers 9 and side brackets 10 with prismatic supports. An additional magazine 11 (FIG. 4) for a replaceable working member — traverses 12 with magnets — is mounted on beams 2 and is made in the form of a cable-blocking device, including a reverse polyspast, to the movable blocks 13 of which the load is suspended

14 interacting with fixative

15, and prismatic supports 16 with planes of contact 17. Additional magazine 18 (FIG. 3) for interchangeable working bodies — welding carriage 19 with semiautomatic machines 20, welding tractor 21, set orientation devices 22, devices for pressing set beams to the panel 23 and etc. mounted on rack 3 of portal 1 and presented

There are a number of brackets 24. A part of the brackets 24 is provided with an actuator 25 for moving them. Each of the replaceable working bodies has main bearing surfaces 26 interacting with the organ 8 and additional supporting surfaces 27 interacting with the supports of the additional stores 11 and 18 or with the supports of the floor magazine 28.

The installation works as follows.

The body 8 is lifted up with the help of telescopic guides 6 of the column 5, providing the crosshead 12 is fitted with the main support surfaces 26 on the side brackets 10 with prismatic support of the body 8 (figure 4), after which the lock 15 is triggered, releasing the load 14. When lowering the lifting body 8 of the yoke 12 is lowered along with it, while lifting the movable blocks 13 with the load 14. With the help of the yoke 12, using the longitudinal movement of the portal 1, they lift, move and stack the sheets (not shown) on the assembly stand. At the end of laying the sheets, the yoke 12 is raised to the extreme upper position, while the load 14 with the movable blocks 13 is lowered down, the latch 15 is activated, securing the load 14 in the lowest position, thereby fixing the yoke 12 to the extreme upper position, in which the main supports the surfaces 26 of the crosspiece 12 interact with the planes of abutment of 17 prismatic supports 16.

Then, the body 8 from the additional magazine 18 (FIG. 3, 15, 16) seizes the next interchangeable working body — the welding tractor 21 — by the main bearing surfaces 26 and is placed on the laid sheets for welding the web openings. At the end of the welding, the welding tractor 21 of the additional 1 nm bearing surfaces 27 is mounted back to the additional magazine 18 on the brackets 24. Similarly, other interchangeable working elements are taken from the additional shop 18 to carry out technological operations for assembling and welding the sections of the kit (Fig. 3, 9-14). At the same time, a part of replaceable working bodies located on brackets 24 equipped with a drive for moving them

25, at the time they are taken by the body 8, they are advanced into the zone of action of the body 8 (Fig. 3). If it is necessary to perform one technological operation at the same time, several interchangeable working elements that are functionally different from each other, for example, pressing the set beams and tacking it to the cloth, body 8 captures the device for pressing the beams to the cloth 23, and on the side brackets 10 with prismatic supports of the body 8 another interchangeable body, for example, a welding carriage 19 with semi-automatic machines 20, and simultaneously tacking them into a panel, also tacking them to the panel (FIG. 9,10) . Similarly, more operations can be performed simultaneously. In the case of repair of replaceable working bodies, they are installed in the floor shop 28 (Figures 5-8).
