Description

I

This invention relates to shipbuilding.

A lighter is known that includes an airtight container in the form of a rectangular parallelepiped with extremities, 5 holds and a bottom, racks with wedge-shaped supports and clamps mounted along the sides of the airtight container, as well as hatch covers mounted in the bow and aft end of the sealed capacitance G.

The disadvantage of this lighter is its low efficiency in exportation.

The purpose of the invention is to improve efficiency in the operation of the lighter.

The goal is achieved by the fact that it is equipped with a ramp, the nose of the HertHETtBB sealed container is made with a U-shaped cutout and is equipped with 20 guiding grooves with rollers and stoppers-locks, and In this, 25 guiding chutes are mounted on the walls of the U-shaped: a notch of the nasal tip, the ramp is mounted in the hold and filled with one of its ends aligned horizontally

U-shaped notch wall, one ends of the guide grooves are made by one I with horizontal wall of U-shaped notch, and their other ends are made with fixing elements, the rollers are mounted rotatably on the grooves, the stoppers-latches are fixed on the horizontal side. the burned wall of the U-shaped notch, the walls of the U-shaped notch made matching with the hinged articulated sections of the hatch cover, and one of the sections is made with sockets matching with the stoppers-clamps, Both of the articulated sections are mounted so that they can move along the guide grooves, and the days .-; e of the bow of the sealed container are inclined to the waterline.

FIG. 1 shows a lighter in isometry, a general view (the retractable hatch cover is shown in the raised position); in fig. 2 - lighter, side view.

The lighter includes an airtight container containing the bottom 1, the beads 2, the aft tip 3, the bow tip 4 with the latch port of the hatch cover, section 5 of which is articulated

connected to the movable section 6. This section 6 in the stowed position is fixed by the guide chutes 7 of the nasal tip, the hatch covers 8, the stop 9 of the hatch cover 10 and the locking elements 11 of the guide chutes. In the working position, the section 6 extends with the help of the rollers 12 and is automatically fastened with fastening sockets 13 on the locking devices 14 of the nose tip. In this position, the hatch cover is used as a ramp. Nosovaya tip sealed container is made with a U-shaped neckline and. The guide grooves 7 are mounted on the walls 15 of the U-shaped notch of the nasal tip. The ramp 16 is mounted in the hold 17 and is made mating with one of its ends with a horizontal wall 18 of the U-shaped notch a. One of the ends b of the guide grooves 7 are made to match with a horizontal wall 18 of the U-shaped notch. The stoppers-clamps 14 are fixed on a horizontal wall 18 of the U-shaped notch. The walls 15 and -18 of the U-shaped notch are made to match the articulated sections 5 and 6 of the hatch cover. The CMOHTH rollers 12 are rotatable on the grooves 7 and on the hatch section 6, closed. Hermetic tank is equipped with racks with wedge-shaped clamps 1 9.

In addition, the lighter can be made with a partial slope of the bottom 1, shown by the dotted line in FIG. 2, which contributes to the maximum approach of the lighter to the coastline.

The lighter operates as follows. In the stowed position, the lighter is loaded and closed with sections 5 and 6 of the hatch cover and covers 8 and 10. With the lighter carrier spreading device, the lighter is lowered into the water and towed to the place of unloading. Then, after removing the stoppers from section 5 of the lap-section, section 6 of the lucky closure extends from the U-shaped aperture, the end of which is nested out 13 with the sockets. locking pins 14, and the front descending to the bottom. The section b is then moved along the guide chutes 7. Thus, the loading and unloading equipment can go through section b, which functions as a ramp, and then along ramp 16, enter from the shore into the hold 17

and perform cargo operations in a horizontal way.

As it is being unloaded, the lighter can be pulled ashore to ensure smooth operation. The closure of the lighter is carried out with the help of a flatbed unit installed in the aft of the lighter.
