The invention relates to the technology of shipbuilding and ship repair and relates, in particular, design of pile lifting-lowering device for heavy ships.

Known serial setup type TGM-75 or TGM-75 to move ships (Trolley stacker leading TGM-75, TU 212 of the RSFSR 901-15-77, THM. 00.00. The FO. We, 1983), which is a biaxial stacker truck with hydraulic cylinder, as well as model ship-carrying multiwheel Kosyakova trolley type G-300 and G-400 with trossoblochnoy system for raising and lowering vessels (Truck lifting SG. Manual SG. 00.00.00.00 re. the construction, the complexity and bulkiness of the design and high operating costs.

The closest to the technical nature of the proposed solution is a device for the construction and descent of the vessel on the water, containing horizontal and inclined track, a traction device, bunk ship-carrying cart with wheel pairs, a locking mechanism, an inclined platform and sloping ground, under which there are rollers and mounted on top of a moving platform with limiters.

The disadvantages of the known device: it is used only for small vessels, which can be installed on one or two devices. For a vessel under which you want to install three or more devices, more difficult to achieve a uniform distribution of the load; it is occupied by the vessel during the entire period of construction or repair, which entails additional operational costs; it does not provide the possibility of changing the direction of the 90aboutdirectly beneath the boat.

The purpose of the invention - improving performance by simplifying and improving reliability while reducing the cost of manufacturing and operating costs give the ship-carrying cart on wheel pairs, in contact with the track of the slip and the traction device, the lower and the upper part of which is implemented as platforms wedge-shaped, superimposed on each other vertices in different directions. A feature of this device is that it added power the hydraulic system, including water systems and three hydraulic cylinders located at the bottom of the device between platforms, while the latter are interconnected hinge on sloping grounds, and the first (lower) cylinder installed in such a way that allows by means associated with the rod specified cylinder support plate to change the direction of movement of the object perpendicular to the original, and the other two parallel hydraulic cylinders to move the platforms relative to each other by means of a deployed roller bearing, mounted on the inclined base of the lower platform, changing the height of the device in the range of 1-2 m

Water systems includes a motor, oil pump and two double valve, and electric panel. A pair of wheels fitted with shock absorbers and attached to the horizontal bases of the berth on the Cabinet or the shutter installation. Moreover, we offer bunk trucks can be docked sections under construction or repair of ships, the installation vessel repair and completion on an even keel with subsequent fixation of the position of the body at berth tables. The proposed design of the device allows to reduce the value of the specific pressure on the hull and 0.125 MPa compared with 0,300 MPa for series trucks, to reduce the load on each wheel truck with 20 TC (serial) to 12.5 cu. The proposed device to move not occupied by the vessel during the entire period of construction or repair. After feeding vessel to the place of repair (completion) and transplant it on the pile of tables the device can be used to service another vessel, thereby reducing operating costs.

The proposed solution is, in addition, provides the opportunity for independent height adjustment of each device (this is especially important when working with heavy ships, when using three or more offer trucks under the vessel), thereby providing a uniform load distribution. When installed under a vessel of three or more of the proposed devices, the movement of the vessel may OssetiaAlania movement directly beneath the boat, transferring the vessel to cross paths on the longitudinal and Vice versa. Only in a constructive combination, missing in all known devices are provided with new properties of the proposed technical solutions and creates a positive effect - improving performance by simplifying and improving reliability while reducing manufacturing cost and the cost of operation of the device.

In Fig. 1 shows schematically the proposed device for moving the vessel, end view; Fig. 2 - section a-a in Fig. 1; Fig. 3 is a block diagram of the water installations.

The device for moving the vessel includes bunk ship-carrying cart, the lower and upper parts of which are made in the form of platforms 1 and 2 are wedge-shaped, superimposed on each other vertices in different directions. Each of these platforms is a spatial welded metal construction and consists of two load-bearing longitudinal vertical bars connected by transverse bracing (not shown). Bunk truck mounted on wheels 3 pairs in contact with the track 4 of the slip. A pair of wheels 3 are made on rubber shock absorbers 5 (Fig. 2) and con is Iranian pressure between the wheels and mitigate the overloads for the design, resulting from uneven lifting of the rails. The device also includes a traction device 6 (trossoblochnoy system with traction winches). The horizontal base 16 (Fig. 2) the upper platform 2 is designed for direct installation of the ship or the ship's hull. On top of the platform 2, a pinned layer made of wooden beams 7, which is set to raise the vessel. At the bottom of the device between platforms 1 and 2 are connected by sloping grounds articulated, is the power the hydraulic system. includes water systems 8 and three hydraulic cylinders 9, 10 and 11. The cylinders 9 and 10 are parallel to each other. With the rod 12 of the first (bottom) of the cylinder 11 is pivotally connected base plate 13, acting on the rail head by means of which the cylinder 11 carries out the direction of the movement of the object perpendicular to the original. The other two hydraulic cylinders 9 and 10 is installed in such a way that allows the moving platforms 1, 2 relative to each other using the expanded roller bearing 14 with the roller stop 15 mounted on an inclined base of the lower platform 1. This changes the height of the device in the range of 1 - 2 m GIDC 19, and electric Board 20 control.

The work of the proposed device to move the vessel is as follows.

Bunk truck is filed under the hull of the ship, standing on the shoals, the height of the device is minimal. After turning the water installations 8 cylinders 9 and 10 move the upper 2 and lower 1 wedge platform relative to each other, thereby increasing the height of the cargo unit. The ship rises and releases Kosyakova truck. The number of trucks corresponds to the number of winding of the rails and is selected depending on the length of the vessel. Trucks are staggered relative to the hull. Using traction devices the hull (and the ship) move the specified distance. For changing the direction of movement by means of the cylinder device 11 is lifted above the rails and deployed on the 90aboutand, thus, is alternately turn all devices employed under the hull. Moving the housing to the desired length, exhibited Cabinet with wooden strips. Cargo devices are exempt from under the vessel by moving the wedge-shaped platforms 1 and 2 relative to each Draken way when the use of the proposed solution provides a simple and user-friendly lifting and trigger the process of moving heavy ships at specified distances with a minimum number of installed under the hull of the device (as shown by tests, required 3-4 times less than the proposed devices in comparison with the known carts). In addition to reducing operating costs, and provided other technical advantages relating to the uniform distribution and independent regulation load on the device, changing the direction of movement of the device directly under the vessel.
