Description

The invention relates to the field of shipbuilding and ship repair, namely to vertical ship elevators.

Known vertical ship elevator containing short-stroke hydraulic jacks, driving the platform using ⁵ gear rods, with a tooth pitch less than the stroke of the hydraulic jacks [1].

The disadvantage of this device is the design complexity of the vertical ship elevator.

The closest technical solution of the known is a vertical ship elevator containing lifting machines, a platform and a support structure to support the hull of the vessel to be hoisted [2].

The disadvantage of this elevator is that vessels are raised or lowered only on the transverse beams, and longitudinal ones are used only as exit bridges, as a result of which there is a need for uneven distribution of supports along the length of the vessel.

The aim of the invention is to ensure the strength of the body of the sunnah during the ascent.

This goal is achieved by the fact that the support structure is made in the form of a ship train of slipway bogies with hydraulic jacks combined in two roll and one trim groups, which moves along rails laid on an articulated platform consisting of separate sections suspended at four points from the lifting machines and transitional bridges, moreover, the sections are interconnected by means of transitional bridges pivotally supported on them.

In FIG. 1 shows a ship elevator, general view; in FIG. 2 is the same. plan view with a hydraulic scheme for combining slipway trolleys; in FIG. 3 - articulated joint of the sections of the platform and the transition bridge; in FIG. 4 - section A - A in FIG. 3; in FIG. 5 - section B — B in FIG. 3.

The vertical ship elevator is designed for lifting (lowering) the vessel 1 and consists of a hydraulic slipway train 2 moving along the rails and a platform, which is an articulation of sections 3 and transition bridges 4. The hydraulic system is combined into three groups - two roll 5 and 6 and one trim 7 The platform sections are suspended at four points by rods 8 to the lifting machines 9. The transitional bridges 4 are articulated on two adjacent sections 3 through the heels 10, and from one. on the side for additional connection of the bridge 4 with section 3, the axis 11 is used. To unload the axis 11 from the vertical load, the holes in the mounting brackets of section 3 are made oval.

The device operates as follows. Before descent, the train 2 is assembled from slipway bogies, the location of which is determined by the need to maintain certain parts of the hull of the vessel to be lifted. The slipway train rolls onto the platform and secures itself, after which the platform with the help of the rods 8 of the lifting machines 9 is lowered to the lower position. The vessel 1 is introduced into the chamber of the ship elevator and is oriented relative to the slipway train 2. When lifting the platform, the vessel 1 sits on the previously raised hydraulic jacks of the slipway carts. If there is a mismatch in the operation of the lifting machines, it is compensated by a system of hydraulic jacks 5, 6, 7, working on the principle of communicating vessels, and a system of transitional bridges 4, pivotally mounted relative to the lifting sections 3.

Upon reaching the required height, the platform occupies a strictly horizontal position and vessel 1 slides ashore.

The presence in the construction of the articulated platform and the slipway moving along the rails laid on it by a hydraulic jack system allows not only to compensate for the mismatch in the operation of the machines that occurs during the lifting (lowering) process, but also makes it possible to arrange the stacking bogies before lifting the ship any places requiring maintaining the hull of the vessel, providing its general and local strength.

The invention relates to the field of shipbuilding and ship repair, namely to vertical ship lifters. A vertical ship elevator is known, which contains short-stroke hydraulic jacks, which set the platforms in motion with the aid of gear rods, with a tooth pitch lower than the stroke of hydraulic jacks 1. The disadvantage of this device is the design complexity of the vertical vessel lift. The closest technical solution of the known ones is a vertical ship elevator containing hoists, a platform and a support structure for supporting the hull of a hoisting vessel 2. The disadvantage of this hoist is that ships are only raised or lowered on transverse beams, and as exit bridges, which results in the need for uneven positioning of the supports along the length of the vessel. The aim of the invention is to ensure the strength of the hull of the vessel in the process of lifting. This goal is achieved by the fact that the supporting structure is made in the form of a ship-carrying train of slip carts with hydraulic jacks, combined into two roll and one trim groups, which travels along rails laid on a platform linked from four suspended at four points to the lifting sections and transition bridges, the sections being interconnected by means of transitive bridges hinged on them. FIG. 1 shows the elevator, general view; in fig. 2 - the same, view in plan with a hydraulic scheme of unloading the slip carts; in fig. 3 - articulated joint sections of the platform and the transitional bridge; in fig. 4 - section A -A on fit. 3; in fig. 5 - BB section per ft. 3. The vertical ship elevator is designed for lifting (lowering) the vessel 1 and consists of 3 moving along the rails an hydraulic dock train 2 and a platform, which is a hinged connection of sections 3 and transition bridges 4. The hydraulic system is combined in three groups - two bank 5 and 6 and one trim 7. The board sections (|) of the form are suspended at four points by the rods 8 to the hoisting machines 9. The transitional bridges 4 pivotally rest on two adjacent sections 3 through five of them, and on one side to additionally connect the bridge 4 and with a section 3 is used axis 11. To the axis 11, unloading the vertical load holes in brackets secured boiling section 3 are oval. The device works as follows. : Before descending, a ship train 2 is assembled from slipway carts, the location of which is determined by the need to maintain certain hull locations of the vessel being raised. The stacker train rolls onto the platform and is fixed, after which the platform is lowered to the lower position by means of shchtang 8 lifting machines 9. The vessel 1 is inserted into the ship elevator chamber and is oriented relative to the berth train 2. When the platform is raised, the vessel 1 sits on the pre: elevated ram jacks of the body rafts. When a mismatch occurs in the operation of hoisting machines, it is compensated for by a system of hydraulic jacks 5, 6, 7 operating according to the principle of communicating vessels, and bridge systems 4 hinged relative to the lifting sections 3. When the required height is reached, the platform takes a strictly horizontal position to the vessel 1 rolls To the shore.
