Description

(54) DOCUMENT CELL

The invention relates to ship repair, and more specifically to the construction of dock cells (supports) for placing ships on them in docks.

A dock cage is known, comprising a base and a telescopic strut pivotally connected to the supporting platform 1.

A disadvantage of the known dock cell is the lack of a device therein for additional control of the cell permutation and regulation of the height of the supporting platform without drying the dock. This makes it necessary to dry the dock twice while docking the vessel and at the same time to carry out additional production operations.

The purpose of the invention is to ensure the movement of the dock cell along the slipway or bottom of the dock and change the height of the supporting platform in the water-filled dock.

The goal is achieved by the fact that the telescopic stand of the dock cage is made in the form of a screw jack, including an upper sliding support, which is made with a toothed crown connected via a gear motor and air guns, which can be adjusted in height on the base, on which a winch was installed to move the dock's horizontal cage horizontally, kinematically connected with an air motor and a switch, and the winch cable was made with a movable stopper, uyuschim switch on the air motor.

The dock cage contains a supporting platform 1, the upper part of which consists of a set of wooden bars placed 15 on rubber compensators to fit the surface of the vessel, and the lower part is designed as a hemisphere; an upper sliding support 2, in the upper part of which there is a hemispherical bed for the supporting platform 1, and a screw-cutting on the inner surface of the surface.

The extendable support is threaded onto a telescopic arm 3 having a screw thread. The rack 3 is fixed on the base 4, on which the frame 5 is also mechanically driven to rotate the telescopic support 2 via gear 7. The latter has a protruding end of the shaft 8 for connecting a power drive to turn the cage out from under the hull of the vessel or enter it under the vessel , standing at the dock. On frame 5, a winch 9 is placed to move the cage along the slipway or bottom of the dock. A cable 10 is wound on the winch drum, the second end of which is fixed to the eye 11, located on the side of the dock to which the cage is to be moved. On the cable 10, a movable stopper 12 is installed which acts on the plug 13 of the switch 14, which serves to turn off the winch air motor 9. On the rod 15, fixed on the base 4, there are mounted pneumatic motor limit switches operating when the cage reaches the upper position 16 and lower 17. Mechanical actuators 18 The winches and extendable support 2 can be operated both with the help of air motors and with the help of hydraulic motors. The dock cell works as follows. At the end of the docking of any vessel, the locations of the cells under the next vessel prepared for docking are determined. Rope cables are fastened to the eyes, attached to the deck of the dock on the side to which the cage is to be moved. Traveling switches 16 and 17 are set to the position to which the cage height should be changed. The cells are connected to each other in series by air hoses: the inlet of the first cell is connected to the compressed air line, and the outlet is connected to the inlet of the next cell. At the end of the docking of the previous vessel, filling the dock with water and ascending the vessel, compressed air is supplied to the trunk. Through the switch 14, it enters the air motor 18 of the winch 9 and causes it to rotate. The winch moves the cage up to the stop of the stopper 12 into the plug 13 of the switch 14, which switches the compressed air from the air motor 18 of the winch to the switches 16 and 17 of the cage position in height. In order to increase the height of the cage, the compressed air passes through the switch 16 into the motor of rotation of the upper sliding support 2, which rotates upwards. When the protrusion reaches the support 2 of the switch 16, it switches the compressed air from the engine of the specified support 2 to the output to the next cell. To reduce the height of the cage, the compressed air is supplied through the switch 17, the extendable support 2 goes down and, acting on the switch 17, switches the compressed air to the outlet. The use of the proposed mechanisms for moving vessels around the deck and changing the height of the dock cage allows these operations to be carried out without draining the dock and thereby eliminating one of the two that were previously used for preparatory operations for each docking. Claims of the Invention A dock cage comprising a base and a telescopic rack articulated with a supporting platform, characterized in that, in order to ensure its movement along the slipway or the bottom of the dock and to change the elevation height of the supporting platform in the water-filled dock, the telescopic support is made in the form of a screw jack, including an upper sliding support, which is made with a ring gear, connected through a brush to the air motor, and air motor switches, which are fixed with the possibility of being adjusted and height on the base, on which a winch is also installed for horizontal movement of the dock cage, is kinematically connected with the air motor and the switch, and the winch cable is made with a movable stopper m acting on the air motor switch.
