Description

The utility model relates to the oil and gas industry and is used for underwater development of soils when laying and repairing pipelines in shallow rivers or in wetlands, i.e. for hydraulic works using an excavator with the necessary buoyancy, and can also be used to transport cargo, equipment, auxiliary mechanisms, etc.

A device for dredging is known, comprising a fully equipped seaworthy pontoon with ballast water, pumping means, a maneuverable anchor, means for recording data on operations performed from means for transmitting such data from the main ship, and also means for performing operations in accordance with with the instructions of the specified main ship using electrical, hydraulic or pneumatic signals, while the device can be completely submersible - patent FR 2477098 A1, E02F 9/06.

The increased complexity, dimensions and weight (115 tons) of this device are due to its intended use for the development of trenches of the seabed; its use for the development of shallow rivers, floodplains, lakes, ponds is practically impossible.

Known multi-purpose modular floating equipment, which can be used to install an excavator in the work on the development of underwater trenches, cutoffs or cleaning various water bodies. The device contains several pontoons interconnected rigidly with the help of special reusable locks. The vessel is equipped with a ramp for entry and exit of self-propelled equipment; special stops are installed on the deck for fixing the excavator.

Moving and holding the vessel in place is carried out using electric winches, an anchor and two pile devices. A diesel generator has been installed to provide electricity to on-board consumers.

The pontoon is equipped with the necessary marine devices - drainage, rescue, towing and mooring - Multipurpose pontoon PU-100, see the Internet.

Difficulties in using the device for the development of shallow rivers, floodplains, lakes and ponds are due to its large dimensions and non-transportability, and the presence of electrical equipment as part of the craft complicates and increases its cost.

The prototype of the utility model is a pontoon, used, in particular, for laying and repairing pipelines, for dredging and hydro-construction works with an excavator, which is a collapsible structure that includes several separate longitudinal and transverse rectangular metal blocks rigidly connected to each other by special locks. The pontoon is equipped with stops for an excavator, a breaker bar, pile pins, a ramp, and mooring bollards. Each block can be transported by road - Pontoon for excavators Aksaymetallokonstruktsii PE-60, see the Internet.

In the prototype, the pontoon body is made of rectangular metal blocks rigidly interconnected by special locks. The streamlined shape of the blocks leads to the fact that the whole structure experiences resistance in water, which reduces its mobility. The presence of special locks reduces the reliability of the mounts and complicates the assembly.

The technical problem solved by the utility model is to create a simple, mobile and reliable design of the unit for underwater development of trenches of various depths and widths.

The stated technical problem is solved by a pontoon for an excavator containing four metal, cylindrical-shaped tight blocks rigidly interconnected by transverse studs, on one side of the end parts of two internal blocks there are ramps for driving the excavator to the corresponding sites located along each upper forming surface of the internal blocks, limiters are made along the platforms, on the other side of the end parts of the two indoor units, stops are made, each of the two outdoor units Ov contains at the top, from the side of each end, mooring bollards and guide cylinders hermetically welded into the body of the block, in which lugs-lugs are made, made with holes at different heights in their upper part.

In addition, special cases of the device suggest the following options:

- each of the blocks is welded from sheet steel with a thickness of 8-12 mm;

- transverse studs are made of metal pipes with a diameter of 273-377 mm;

- the limiters are made in the form of pipes with stiffeners welded to the corresponding indoor units;

- lugs-lugs made in the form of sealed pipes with a bevel in the lower part;

- ramps and platforms for the excavator are equipped with rigid hooks from a metal bar.

In FIG. 1 shows the design of the pontoon for an excavator, figure 2 is a view of the device in working condition.

The pontoon for an excavator is a prefabricated structure and contains four metal, cylindrical-shaped tight blocks 1, 2, 3, 4, welded from sheet steel with a thickness of 8-12 mm.

Blocks 1-4 are interconnected by transverse studs 5 made of metal pipes with a diameter of 273-377 mm in accordance with the dimensions of the blocks.

The use of steel pipe 5 to connect the blocks to each other allows for easy and convenient assembly of the pontoon.

On one side of the end parts of the two indoor units 2, 3 there are ramps 6, 7 for the excavator to enter and exit to the corresponding platform 8, 9: from ramp 6 to platform 8, from ramp 7 to platform 9. Each platform is located along the upper generatrix the surface of the corresponding block 2, 3; along the platforms 8, 9, restrictors 10, 11 are made in the form of pipes with stiffeners welded to the corresponding indoor units 2, 3.

On the other hand, the end parts of the blocks 2, 3 are made stops 12, 13.

For reliable retention of the excavator when moving along the ramps 6, 7, they are equipped with rigid hooks, for example, in the form of a welded metal bar.

In the raised position, the ramps 6, 7 hold the excavator on the platforms 8, 9 during operation. For the same purpose, stops 12, 13 are made on the opposite side from the ramps 6, 7, and the platforms 8, 9 themselves, as well as the ramps 6, 7, are equipped with rigid hooks from a welded metal bar.

Each of the two outdoor blocks 1, 4 contains at the top, on the side of each end, a guide cylinder 14, 15, 16, 17, hermetically welded into the body of the block: cylinders 14, 15 are welded into the block 1, cylinders 16, 17 are welded into the block 2.

In the guide cylinders 14, 15, 16, 17, the corresponding latching lugs 18, 19, 20, 21 are placed - sealed pipes with a bevel in the lower part, which serve to fix the pontoon into the bottom of the reservoir.

Lug clamps 18, 19, 20, 21 are made with holes at different heights in their upper part: when the pontoon floats, all lug locks 18, 19, 20, 21 are in the raised position due to their fixation (by any means, for example, using the locking pin) in the respective guide cylinders 14, 15,16,17. For fixing at the place of work, the locking pins are inserted into the upper hole, releasing the lugs, which abut against the bottom of the reservoir, ensuring reliable pontoon fastening.

Each of the two outdoor units 1, 4 contains at the top, on the side of each end, mooring bollards 22, 23, which are used not only in the process of setting the pontoon to the berth, but also when insuring the excavator by fixing it with tie ropes, which are fastened on one side supporting frame of the excavator, and on the other - for mooring bollards 22, 23.

The movement of the pontoon through water is provided by the stroke of the bucket of the excavator 24 - FIG. 2.

Pontoon mass - 60 tons, length - 11 m, width - 8 m, height - 1.7 m,

These indicators are correlated with the mass-dimensions of domestic pontoons, but they are inferior to those proposed in ease of use, mobility and reliability.

The absence of its own engines, winches and other drive equipment for the pontoon simplifies and cheapens it.

Blocks of the pontoon do not go beyond the dimensions of the euro truck, which ensures its free transportation.

The design of the pontoon is simple and does not require a large number of workers for maintenance, allowing it to be operated using only the driver of the excavator and slinger.
