Description

This invention relates to the mechanization of ship repair and diving operations.

Installations for underwater ship repair are known, comprising a sealed chamber with portholes, an operator’s life support system and a device for submerging, moving and performing work underwater, as well as a replaceable working tool.

However, devices used for lowering installations, for example, a winch with cables, do not provide for maintaining installations in a necessary place. In addition, moving a diver to a new job requires lifting it to the surface, which limits the use of ship repair facilities.

The purpose of the invention is to provide conditions for work close to ground.

This goal is achieved by the fact that the device for submerging, moving and performing work under water is made in the form of a trolley traveling along the rails along the pier with a figured cantilever frame lowered into the water, equipped with a support roller at the free end and equipped with guide rails, along which the cage moves, equipped with a telescopic truss, carrying at the retractable end an airtight chamber with portholes and a manipulator embedded in it.

on which the replaceable working tool is fixed.

In order to ensure the static stability of the diver on the underwater work

A working platform is attached to the manipulator torus.

The drawing shows the proposed installation, the overall look. A supporting carriage 1, which may not be visible along the bead of the ship, and the rails 2, which are laid on the wall, is visited by a figurative console frame 3 with guide rails and a support roller 4. The frame rails can be moved

a cage 5, equipped with a telescopic truss 6, carrying a sealed chamber 7 with portholes 8, a lamp 9 and a manipulator 10 for performing various vessel-supporting operations. On the manipulator torus can

any replaceable working tool should be fixed 11.

The proposed installation works as follows.

After the ship is nailed up to a wall at a distance that allows the cantilever frame 3 with chamber 7 to pass along the ship, the latter, together with the operator, is lowered along the guide rails to the required depth.

Using a telescopic truss 6, the operator brings the camera 7 directly to the work site on the ship's hull, and, observed through the windows 3, controls the manipulators 10, supplying the working tool 11 to the ship's hull. At the command of the operator, the trolley 1 moves along the side of the vessel, while the operator holds the manipulator 10 with the working tool 11 at the hull of the vessel, the wire repairs. Similarly, repairs are performed when the camera is raised.

In the case of work that requires manual labor, a platform can be attached to the manipulators to accommodate divers. At the same time, the operator controls the manipulators from the camera, bringing the platform with divers to the place of work.

Subject invention

1. An installation for underwater repair of vessels, comprising a sealed chamber with portholes, equipped with an operator’s life support system and a device for submerging, moving and performing work underwater, as well as a replaceable working tool, characterized in that, in order to ensure working conditions close to ground, a device for lowering, moving and performing work under water is made in the form of a trolley moving along the rails along the pier with a figured cantilever frame attached to it and lowered into the water the bottom end is a supporting roller and equipped with guide rails, on which the stand moves, equipped with a telescopic truss, carrying at the retractable end a sealed chamber with portholes and a manipulator embedded in it, on which a replaceable working tool is fixed.

2. Installation but n. 1, characterized in that, in order to ensure the static stability of the diver in the area of underwater work, a work site is attached to the manipulator.
