Description

The invention relates to technical means for sampling soil from the bottom of water bodies, in particular to the mechanization of launching operations carried out with long-length core samplers on the deck of a vessel.

The purpose of the invention is to increase the efficiency of the tilter by increasing the level of mechanization of tilting operations with the sampler.

This goal is achieved by the fact that in the known tilter of marine samplers containing vertical posts rigidly fixed on the deck of the vessel, a support associated with vertical posts, and a shaft with a grip, it is equipped with a carriage with a block, and the support is made in the form of a guide frame, installed across the side of the vessel, equipped with blocks in the outboard and above-deck parts and a horizontal axis connected to the vertical posts, directed along the side of the vessel, while the shaft with the grip is fixed in the carriage, the carriage is made with movement along the guide frame, and the guide frame - with the possibility of rotation on the horizontal axis until it stops against the side of the vessel or rigid fixation relative to the vertical struts.

It is known to use in the tilter of marine samplers the mechanization complex KM0-1 of a guide frame made in the form of a curved gutter installed across the side of the vessel. In a known tilter, the sampler is moved from the overboard position to the above-deck position by pulling it along the gutter, i.e. in a position perpendicular to the side of the ship. This makes it necessary when working with such a tilter large working areas on the deck of the vessel and, therefore, low efficiency. When sampling from small-tonnage vessels with extended projectiles, the use of a known tilter becomes generally impossible.

In the proposed tilter, a guide frame mounted across the side of the ship allows the sampler to be moved from the overboard position to the above deck position in a position parallel to the side of the ship. This eliminates the need for large areas on the deck of the vessel for tilting operations with the sampler, increases the convenience of the staff, and ultimately increases the efficiency of the tilter.

In FIG. 1 shows a general view of tilters; in FIG. 2 is a top view at the time of transferring the sampler from the overboard position to the above deck; in FIG. 3 - view

above, at the time of transferring the sampler from the above-deck to the outboard position.

The tilter of marine samplers consists of vertical racks 1, rigidly fixed on the deck of the vessel and interconnected by an axis 2 (Fig. 1). A guide frame 3 is mounted on the axis 2 of the vertical struts 1, placed across the side of the vessel and equipped in the outboard and above deck parts, respectively, with blocks 4 and

5 5 mounted vertically. To prevent rotation of the guide frame 3 on the axis 2 during turning operations, the frame 3 is provided with a jib 6 with a lock made in the form of a finger 7,

0 placed in the hole of the vertical post 1. As guides 8 of the frame 3, channels with a longitudinal internal groove are used.

On the guide frame 3 is installed

5, a carriage 9 with rollers 10 located in the internal grooves of the guides 8. On the side of the carriage 9 there is a shaft 11 with a gripper 12 for a sampler 13 connected to a winch on a ship (not shown) with the help of a cargo rope 14 (Fig. 2 and 3 ) The grip 12 is made in the form of two half-clamps 15 and a clamp 16 tightening them. In addition, the carriage 9 is provided with a block 17 mounted horizontally.

The device operates as follows.

After the completion of the drilling process, the sampler 13 is raised to the surface by means of the cargo rope 0 14 of the ship's boom and winch. In this case, the tilting carriage 9 is located in the outboard part of the guide frame 3.

The sampler 13 is lifted overboard 5 of the vessel to such a height that its center of gravity is slightly higher than the level of the shaft 11 at which the grip 12 is fixed. Next, the sampler

13 winds up in open grip 12 and with

0 by means of a clamp 16, tightening the half clamps 15, is fixed therein. Freight rope

14 is discharged from the winch and the sampler 13 under its own weight, rotating on the shaft 11 of the capture 12, lies on the carriage 9 5 of the tilter, occupying a horizontal position.

Further, the weakened freight rope 14 is wound under the block 17 of the carriage 9 and the block 5 in the above-deck part of the guide frame 3 of the forklift. Tension is created

freight rope 14 winch (Fig. 2). As a result, a force arises on the tilter carriage 9, which moves it from the outboard part of the guide frame 3 to the above deck. In this case, the rollers 10 of the carriage 9 move along the internal grooves of the guides 8, providing a smooth movement of the carriage 9.

In order to extract the core from the sampler, a slope is required to the side of the bottom of the shell. To this end, glorify. cargo rope 14 and it is withdrawn from blocks 17 and 5. Then, by tensioning the cargo rope 14, the required inclination of the sampler to the deck of the vessel is created.

If it is required to lower the sampler 13 from the tilter to the deck of the vessel for the purpose, for example, of its complete disassembly or other tasks, the cargo rope 14 is passed under block 5 in the above deck part of the guide frame 3. Next, knock it out of the hole of the vertical strut 1, the finger 7 of the jib 6 and, gently lifting the rope 14 from the winch, lower the frame 3 rotating on the horizontal axis 2 onto the deck of the vessel.

The tilters are moved in the reverse order to put the tilters in working position. By tensioning the cargo rope 14, passed through the block 5, raise the above-deck part of the guide frame 3 up to the rest of its other part on board the vessel. In this position, the guide frame 3 is fixed by installing the finger 7 of the jib 6. in the hole of the upright 1.

The sampler 13 is also brought into the outboard position by tensioning the cargo cable 14, which in this case passed through the block 17 of the carriage 9 and the block 4 in the outboard part of the guide frame 3 (Fig.

3). After moving the carriage 9 with the sampler 13 to the outboard part of the guide frame 3, loosen the cargo rope 14 and remove it from the blocks 17 and 4. Then, by pulling the cargo rope 14, the sampler 13 is moved to the vertical position. After the capture 12 has been released, the sampler 13 is ready for descent to the bottom.

The use of the proposed device will dramatically reduce the share of manual labor, as well as eliminate direct physical contact between the drilling personnel and the sampler when it is tilted across the side of the vessel. it will increase the convenience and safety of the staff when performing turning operations, will increase the efficiency of use of turners.
