SU388953A1 - DEVICE FOR DRAWING FLUATING MEANS ON WATER - Google Patents

Description

The invention relates to iK hydraulic engineering and can be used for launching Maos | VOv-giants, sections of tunnels for underwater transitions, .HOHTOHOIB, etc.

Descenders are known in the side of oklizovy or slip tracks, on which a free (under the action of its own weight) or control is (m) (1 winch) descent built on the shore, the product is launched into the water.

However, all of the known release devices have significant drawbacks.

During the descent of floating equipment with unit loads for 1 pog. m products of ov. above 100 tons, the most advanced sklyznye devices are unreliable because of the static uncertainty of the distribution of loads on a large number of launch tracks and the uncertainty of the coefficients of friction. The use of capital slip-off devices with tracks on pile foundations with special equipment requires considerable capital investments, which is small, and the cost of building products is environmentally inappropriate.

The aim of the invention is to increase reliability and reduce the cost of launching floating equipment to the water, as well as controlling the speed of descent.

This is achieved in that the device for

The vessel's buoyant means of water are made up of two hollow wheels consisting of several shariro-articulated segment beams and inside which the craft is placed.

In addition, IT is equipped with cable drums installed on the outer sectional beam beams, into which the rope is wound from coastal brake winches.

FIG. 1 shows the floating means installed “and the trigger wheels, front view; in fig. 2 - Floating means with a trigger wheel mounted on it, and a cross-section; in fig. 3 - side view of the product launched and the links of the wheel unbuckled from the product.

A device for launching (floating equipment on water is made of two hollow wheels 1 mounted on the product and then launching it on the water. The wheels are lowered on an inclined plane with xiped soil and a relatively small weight of the product either directly on the ground or: stone and rubble.With weak soil or excessively heavy weight of the product, the wheels are moved along wide sliding tracks 2 with reinforced topsides.

Each of the tandem hollow wheels / consists of several segment beams-pontoons interconnected by hinges 3 with stitched heads and articles. The segmental balcaponton is itself a three-dimensional structure that transmits its load from ees. descendant craft to the descents. For convenient and quick disassembly and removal of the 1 wheel from the floating equipment, the wheel segments are given zero buoyancy and three Aid buoyancy blocks.

The outer walls of the segmented beamers are attached to: cable troughs 4, onto which, after assembly, the wheels are mated like drums, drawn: ropes 5 from shore brake winches (not shown).

In order to better distribute the pressure between the product and the surface of the segmental pontoon beams, elastic pro, clavix 6 are laid.

The device works as follows.

The underbuilt; floating craft at the locations of the runways leads down the lower sections of the segmented pontoon beams. Segmental beams, pontoons insure against arbitrary rotation. The product is rearranged to the hacksit, freed from construction o.pore and lowered onto the segmental beams-pontoons. Then using the crane serves the side sections. With the help of talted sections, the sections are brought together to coincide the holes in the hinge holes and are connected to B wheels so that the surfaces of the sections fit tightly without gaps to the entire surface of the product. Structural defects of the floating equipment and sections do not affect the tightness due to elastic gaskets. From the coastal brake winches, the ropes are guided, laid into the cable troughs and fastened at the ends of the hinged joints to the end of that section, which after the lowering and the ascent of the product will be on top. If the product has open holes at the top or at the ends, they are hermetically sealed by Time-1m1 | stub.

After the end of the preparatory work, the opuo. Winches, and choose slack ropes, take out safety stoppers from under the wheels and, becoming jacks under the wheels, roll the product to the beginning of the inclined plane, that is, before tensioning the lebe.Doc under its own weight

products. After that, by undercutting the ropes from the drums of the winches, the wheels are moved along an inclined plane until the product emerges. After the ascent of the product, the rope rolls are unfastened from the wheels. Then, by pulling the cable, they are removed from the grooves on the wheels and at the same time freely wound them on the winch. The end of one of the ropes attached to the upper segment of the wheel, disassemble one LINE of the articulated joints of the segments, unfasten the wheel and remove it from the water to the shore using one of the brake winches.
