Description

The invention relates to shipbuilding, in particular, to a device for moving ship hulls or parts thereof at a construction site.

The aim of the invention is the expansion of technological functions.

FIG. 1 shows the device, a general view, in axonometry; in fig. 2 - the same side view; in fig. 3 - the same plan view; in fig. 4 is a view A of FIG. 2; in fig. 5 is a section BB in FIG. 3; in fig. 6 is a sectional view BB in FIG. five; in fig. 7 shows the structure of a spring loaded roller of the lower beam (node I in FIG. 2); in fig. 8 shows a detachable unit for connecting a transport carriage with a support (unit II in FIG. 5); in fig. 9 - installation of the vessel hull module on the indicated devices.

The device consists of a support 1 (Fig. 1 and 3), consisting of a platform 2, mounted on four racks 3. Between the racks 3, a lower beam 4 is installed in one of two mutually perpendicular directions.

The installation direction of the beam 4 coincides with the direction of movement of the device.

On the lower beam 4 on a rail track x 5 (Fig. 4) a transport carriage 6 is installed.

The hydraulic cylinder 7 (Fig. 2) of the drive for the mutual displacement of the lower beam 4 and the carriage 6 in the horizontal plane is fingulously fixed on the lower beam 4. The rod 8 of the hydraulic cylinder 7 is hingedly connected to the trolley 6. On the trolley 6, the hydraulic cylinder 9 (Fig. 5) is fixed to drive the relative movement of the support 1 and the trolley 6 in a vertical plane.

On the underside of the square 2, a support 10 is installed, connected to the rod 11 of the hydraulic cylinder 9 (Fig. 8) by means of a detachable connection in the form of a flange 12 and hinged bolts 13. The mating surfaces of the support 10 and the stem 11 are spherical.

The lower beam 4 is equipped with rollers 14 (Fig. 2, 7), equipped with hydraulic heads 15 for movement in a vertical plane.

On the upper side of the platform 2 of the support 1 there is a centering support (FIGS. 2, 5) for supporting the transverse beam 16, on which the floating hull module 17 is mounted. The centering support is made of any known construction and provides movement of the housing module 17 in three mutually perpendicular directions (i.e., along the longitudinal and transverse axes of the support 1, as well as raising and lowering the module 17 relative to the working surface of the support 1).

The centering support consists of an upper plate 18 (fig. O) on which a transverse beam 16 is installed together with a module 17. The upper plate 18 is mounted on the lower plate 19 connected to the rod

hydraulic cylinders 20 for raising and lowering the lower 19 and upper 18 plates relative to the working surface of the support 1. The housing of the hydraulic cylinder 20 is fixed directly on the platform 2 of the support 1. Four hydraulic cylinders 21 are placed in the bottom plate 9 (FIG. 6), pairwise oriented along the longitudinal and transverse axes .

The rods 22 of the hydraulic cylinders 2 interact with the upper plate 18 of the centering support.

The device works as follows.

The ship hull module 17 assembled on the transverse beams 16 in the workshop or on the assembly platform is installed, for example, on four devices, so that the transverse beams 16 are mounted on the upper plates 18 of the centering supports (Fig. 4, 9). The lower beam 4 and the supporting surfaces of the posts 3 of the support 1 are installed on the floor of the workshop or surface of the assembly site. In this case, the lower beam 4 is oriented along the direction of movement, for example, along the longitudinal axis of the building site.

With the help of a hydraulic cylinder 9, they lift the support 1 1 with the module 17 above the floor of the workshop. Then, with the legs of the hydraulic cylinder 7, move the transport trolley 6 together with the support and module 17 along the rail track 5 to the Russian station. determined by the course of hydro11H.; 1in, t, r.h 7,

At the same time, the rollers 14 themselves are installed on the floor of the workshop. The possibility of sharing unhindered

5 lifting of the transport carriage 6 and the lower beam 4 is provided by means of a hinged fastener of the hydraulic cylinder body 7 on the lowermost beam 4 and its rod 8 on the trolley 6. After that, using the hydraulic cylinder 7, the lower beam 4 on the rollers 14 is moved equal to the distance of the previous movement of the transport carriage 6. Then, by means of the hydraulic cylinder 9, the carriage 6 is lowered and, accordingly, with the bottom: a new beam 4. The springs 15 are compressed

5 BEFORE contact of the bottom surface of the bottom beam 4 with the floor of the workshop.

For the last movement of the vessel hull module 17, the entire cycle is repeated.

After transporting the module 17 by means of these devices to the building site to the docking site with other modules of the device, the bottom beam 4 and the supporting surfaces of the uprights 3, the supports 1 are mounted on the surface of the construction site. After that, the hinged bolts 13 (Fig. 7) are removed from the flange 12 and the support 10 is disconnected from the rod 11 of the hydraulic cylinder 9. The hydraulic cylinder 9 is turned on and the rod 11 is lowered until a gap is formed between the support 10 and the rod 11.

With an atom, the action of the spring 15, the lower beam 4 is raised above the surface of the construction site. Then, with the aid of a t gacha (not shown), the lower beam 4 together with the transport carriage 6 is brought out of the limits of the support 1 and transferred back to the workshop for the next transport operations.

Module 17 on the transverse beams 16 is installed at the same time on the upper plates 18 of the centering supports (Fig. 9).

Moving the module 17 along the longitudinal and transverse axes of the support 1, as well as

raising and lowering of module 17 relative to the working surface of support 1, necessary when it is centered with modules and already installed at the construction site, are carried out using hydraulic cylinders 20 and 21 of the centering support.

If it is necessary to move the module 17 perpendicular to the axis of the building site, the lower beam 4 together with the cart b is again placed under the support 1 perpendicular to its previous position (Fig. 9) so that the beam 4 is directed perpendicular to the axis of the construction site. The possibility of installing the lower beam 4 with the carriage 6 in two mutually perpendicular positions under the support 1 is ensured by the presence of four posts 3 spaced at a distance sufficient to install the beam 4 in the indicated positions.

After installing the beam 4 with the carriage 6 under the platform 2, the supports 1 connect the support 10 and the rod 11, after which all the above operations necessary for moving the device are repeated.
