This technical solution is made as the closest analogue of the present invention.

The closest analogue relates to the transport system and is designed to move ship structures of various sizes when feeding them to a given slipway position.

However, in addition to the transport system consisting of slipway trolleys with hydraulic jacks, the equipment of the slipway for mounting the gondola propulsion and steering complex is not provided in the closest analogue, and the need for equipment arises at modernized enterprises after the construction of new slipways or the retrofitting of existing slipways or platforms for large-sized ship structures.

The present invention is based on the solution of the problem, which allows to increase and expand the technological capabilities of equipment and inclined lifting to a regular place for installation on a slipway of heavy and bulky ship equipment.

The technical result of the present invention consists in a new technology for the implementation of the equipment: a transport system consisting of a collapsible double-track rail rack with stops, a main and safety traction systems, a transport set consisting of four stacking trolleys with hydraulic jacks connected by a rigid frame, and a support system of metal pedestals, together forming a transport and lifting complex with a horizontal supporting surface under a common transport frame with a gondola propulsion wheel vym complex, and in the process of mounting the gondola the propulsion performance using the new equipment technology.

According to the invention, this problem is solved due to the fact that the equipment for installation of ship equipment contains a transport system including a transport kit moving along rail tracks and consisting of four slipway bogies connected by a rigid frame and longitudinal rods, with hydraulic jacks built into each of them, connected to a common pumping station.

The equipment for the installation of ship equipment is made comprehensive with the possibility of mounting the gondola propulsion and steering complex on an inclined slipway.

The equipment contains a support system made of metal pedestals, and a transport system consisting of a double-track rail overpass, a transport kit and traction systems.

The double-track rail overpass is made collapsible with stops from spontaneous rolling and forms a parallel surface of the plane of the body of the slipway.

Traction systems consist of the main and insuring independent traction systems.

The rigid frame of the transport kit is made of four beams with bow and stern supports, forming a horizontal supporting surface under the common transport frame with a gondola propulsion and steering complex and with the possibility of precise centering in the horizontal plane by applying markers verified by optical instruments on a rail mounted on a flyover transport kit.

Installation is carried out using the proposed equipment.

Using a traction system, the transport kit with the gondola propulsion and steering system is moved along the rail tracks of the overpass to the installation site and fixed with stops. The hydraulic systems of the hydraulic jacks of the stacking bogies are connected to the pump station.

Hydraulic jacks raise the stacking trolleys of a rigid frame with a gondola propulsion and steering complex by the amount of their stroke.

The lifting is carried out alternately by each hydraulic jack, manipulating the gaps between the outer surface of the head of the nacelle and the inner surface of the steering column of the propulsion-steering complex.

A number of bars are laid in the gap formed between the rigid frame and the surface of the support system, and wedges are knocked into the formed cracks.

The hydraulic jacks of the transport kit are lowered to their original position, the rigid frame with the gondola propulsion and steering complex remains stationary on the support system, but raised to the steering column to the height of the hydraulic jacks.

On the supporting surface of the hydraulic cylinders of the stacking bogies, a large supporting surface is formed of metal plates, beams and wedges up to the stop in the lower surface of the rigid frame.

A secondary lift is made and the height of the support system is increased on metal cabinets and repeated.

Then lower the hydraulic jacks with their bearing surface to the initial position, the operation of increasing the height of the supporting surface on the hydraulic jacks is repeated.

Lifting cycles are repeated until the gondola propulsion and steering complex is raised to the required height.

At the same time, during the lifting of the gondola propulsion and steering complex, support systems are formed in the form of formed blocks of beams in several layers, each layer of which has a cross-shaped layout with respect to the adjacent layer.

The equipment for the installation of ship equipment is made comprehensive with the possibility of mounting the gondola propulsion and steering complex 1 on an inclined slipway.

The equipment contains a double-track rail overpass 2, a transport kit 5, a main traction system 12, a safety traction system 13, a support system 15.

The double-track rail rack 2 is made collapsible with stops 3 from spontaneous rolling and with a bearing surface 4 parallel to the plane of the slipway body.

Collapsible rail rack 2 is made of the required length and is installed parallel to the axis of the inclined slipway.

The transport kit 5 contains four stacking bogies 6, a rigid frame 8 and two pairwise longitudinal rods of the bogies 11.

Four slipway trolleys 6, with hydraulic jacks 7 built into them, are connected by a rigid frame 8, which makes up a transport set 5 with a lifting platform controlled by a pump station.

The load capacity of the slipway trolley is 6-100 tons. A hydraulic jack 7 with a lifting capacity of 100 tons is installed in the housing of the slipway trolley 6. The hydraulic jack 7 consists of a housing, a cylinder, a plunger with cuffs (not shown). A centering device is made in the hole of the plunger, consisting of lower and upper supports, ball bearings, release bolts (not shown), with the help of which exact alignment and joining in the horizontal plane are carried out.

The hydraulics of the stacking bogies 6 are connected to the pump station. The load on the stacking carts 6 is different. The axis of the hydraulic jacks 7 of the stacking bogies 6 are parallel to the lifting axis or the axis of the nacelle of the propulsion-steering complex 1.

The rigid frame 8 is made of four beams with bow and stern supports 14, forming a horizontal supporting surface under a common transport frame with a gondola propulsion and steering complex. For accurate alignment in the horizontal plane, markers aligned with the optical instruments from the axis of the steering column 10 are applied to the rigid frame.

Rigid frame 8 is formed from beams for the appropriate load.

Traction systems are formed from the main traction system 12 and the safety traction system 13 for transporting the transport kit 5 with the nacelle of the propulsion-steering complex 1 for a regular place.

The total tractive effort is calculated. For this, standard winches on the slipway are used.

The rigging equipment is selected by calculation: butt, staples, rosin blocks, tackles, ropes, anchor points.

The steering column axis 10 is projected (the standard location for the nacelle of the propulsion-steering complex 1) in the form of markers on the rigid frame 8 of the transport kit 5. When loading the nacelles of the propulsion-steering complex 1 on the rigid frame 8 of the transport kit 5 markers applied by the supplier of the transport frame of the gondola propulsion-steering complex 1 is combined with markers deposited on the rigid frame 8 of the transport kit.

After installing the nacelle of the propulsion and steering complex 1 on the rigid frame 8 of the transport kit 5, the main traction system 12 and the safety traction system 13 are turned on to move the transport kit 5 with the gondola 1 along the double-track rail overpass 2.

After the axes of rotation of the nacelle 9 and the steering column 10 coincide, the main 12 and the insurance 13 the traction systems are turned off, the transport set 5 is fixed with stops 3. Before lifting the nacelle, the main traction system 12 is dismantled, the insurance traction system 13 remains when the ropes are loosened.

The support system 15 is made of metal pedestals. Curbstones 15 are designed under the rigid frame 8 of the transport kit 5 for lifting the nacelles of the propulsion-steering complex 1.

The surfaces of each cabinet 15 form a horizontal plane. The minimum clearance between the pedestal 15 and the rigid frame 8 of the transport kit 5 is 50 mm. Curbstones 15 are installed on beds (not shown), the surface of which is horizontal.

Installation is carried out using the proposed equipment.

The transport set 5 with the gondola propulsion and steering complex 1 using traction systems 12 and 13 is moved along the rail tracks of the overpass 2 to the installation site and fixed with stops 3. Before lifting the gondola, the main traction system 12 is dismantled, the safety traction system 13 remains when the ropes are loosened.

The hydraulic system of the hydraulic jacks 7 of the stacking bogies 6 are connected to the pumping station.

Hydraulic jacks raise 7 stacking trolleys 6 of a rigid frame 8 with a gondola propulsion and steering complex 1 by the amount of their stroke.

When the rams of the hydraulic jacks 7 are extended by 200 mm, the hydraulic system is locked.

The lifting is carried out alternately by each hydraulic jack 7, manipulating the gaps between the outer surface of the head of the nacelle and the inner surface of the steering column of the propulsion-steering complex 1.

In the gap formed between the rigid frame 8 and the surface of the support system 15, a number of bars 16 are laid and wedges 17 are knocked into the formed cracks.

The hydraulic jacks 7 of the transport kit 5 are lowered to their original position, the rigid frame 8 with the gondola propulsion and steering complex 1 remains stationary on the support system 15, but raised to the steering column by the height of the hydraulic jacks 7.

On the supporting surface of the hydraulic cylinders of the stacking bogies 6, a large supporting surface is formed of metal plates (not shown), beams 16 and wedges 17, all the way into the lower surface of the rigid frame 8.

Produce a secondary rise and increase the height of the support system on the metal pedestals 15 repeat.

Then lower the hydraulic jack 7 with its bearing surface to its original position, the operation of increasing the height of the bearing surface on the hydraulic cylinders is repeated.

Lifting cycles are repeated until the gondola propulsion and steering complex 1 is raised to the desired height.

At the same time, during the lifting of the gondola propulsion and steering complex 1, support systems are formed in the form of formed blocks of beams 16 in several layers, each layer of which has a cross-shaped layout with respect to the adjacent layer.

The slipway trolleys 6 (carrying capacity 100 t) have a limit on the lifting height of up to 220 mm.

The gondola propulsion and steering complex 1 must be raised to a height of 1000 mm with a slope of 4.8 ° to the axis of the slipway or with an offset of 5 cm along the slipway axis.

The principle of lifting with stackable trolleys is 6-speed and each lifting is 200 mm.

The proposed equipment and method of transporting and lifting the gondola propulsion and steering complex for its installation in place was carried out using known devices, equipment and technologies that are widely used in shipbuilding. The installation of the Azipod-type propulsion and steering complex at the Admiralty Shipyards OJSC using the proposed equipment determines, in the applicant’s opinion, compliance with its criterion of “industrial applicability”.
