The invention relates to shipbuilding, in particular to a lifting device for arming/sample trailed lines.

You know the widespread use of towed lines, equipped with measuring equipment for examination of various horizons in the water column. Instrumentation, depending on tasks, installed or in special underwater vehicles with globeteam and buoyancy elements, or distributed along the length of the load-bearing rope. For steady motion in the plane of the towing load-carrying rope tow line is equipped with a fairing, resulting in a towed line is a ribbon of modular design, with limited flexibility.

Therefore, an important task is to ensure the integrity of the tow line when setting/sample, which uses tripping devices of various designs.

So, for example, ship launching system [1] for underwater vehicle contains towing winch with crookedholm for the cable and guide the tray, the ends of which are pivotally connected with the holder guide roller and crookedstar winch. For lowering-lifting underwater vehicle via a rotary frame capture.

In the ship the device [2] for towing underwater vehicles on the I speed setting/sample cable propose the construction of a sending node of the two blocks and roller, mounted for rotation on the two shoulders of the levers, which are mounted on a yoke supporting a pulley located at the aft end of the ship.

When using a tow line long length (200-300 m) for single layer-by-layer stacking requires a drum more than 2 m in diameter, and its vertical staging, as in the above analogues, impractical, because of the great weight of the line is complicated by the task of providing the desired tension during its installation without damaging the line.

Known lifting device, tow line, using the towing winch with a horizontally mounted drums [3, 4].

In the device [3] used hydraulic winch, providing traction 3-3,5 TC, and the etching speed of 5-15 m/min, and a stationary inclined slip installed between the space on the upper deck of the vessel to accommodate globitel tow line and the lower deck. At the base of the slip is made Luke inclined mine Clusaz, through which globitel falls overboard a ship. For holding the tape tow line to the inclined slip between the towing winch and the location of globitel has two vertical support guides for tensioning line by etching with a winch.

This lifting device is limited when is the change due to that occupies a large area and requires special equipment of the vessel. In addition, the device does not provide protection against drafts fairings and their breakage when laying the line on the drum.

In the device [4] the premise that hosts tripping device towed the line, located in the Central part of the vessel and occupies a much smaller area due to the use of rotary slip. However, this device does not have means of protection against twisting and drafts towed the line on the winch drum when the production/sample.

Other analogues tripping devices towed the line, using the towing winch with a vertical axis of rotation of the drum, is not revealed.

Problem to be solved is to prevent violations of the single-layered winding towed the line in the process of its installation on the drum towing winch and etched with him.

The invention consists in that the locking device towed the line on the drum towing winch having a vertical axis of rotation, includes rack in the form of a pipe, on which is mounted a rotating drum with a brook for rope through a pulley system associated with the adjustable cargo moving within the rack, and a Creek to the tension of the tape that covers the tow line with what zmoznostjo move in the stream of the drum towing winch as styling/grazing orbits tow line, and secured its second end to a fixed base rotating supports, spaced from the rack in sector 50°-60° relative to the axis of rotation of the drum towing winch, with adjustable load is made in the form of a set of removable disk.

The invention is illustrated by drawings, on which:

In the tubular frames of the sides of the platform 2 of the slip set levers 13, deployed around a horizontal axis, which is installed in the sidewalls of the crossbar 14.

Tow line 15 (see figure 2) contains the load-carrying cable 16 reinforced plastic (kaprolon) fairing 17 installed with clearances to provide flexibility towed the line, both longitudinal and transverse planes.

For ease of Assembly towed the line and, if necessary, replace the damaged fairings 17 each made of two pivotally connected parts with fixation elements, forming a latch. On the inner side of both parts of the fairing is made symmetrical recesses forming a cavity for laying of load-bearing rope 16, the electric cable 18 connecting measuring sensors and instruments installed on the tow line, with equipment installed on the vessel and hose 19 water intake./p>

In order to avoid damage to the cables 18 and the hose 19, stretch under their own weight when setting and towing the line carrying the rope 16, set (pressed) sleeve 20 with clamping collars 21 which are rigidly fastened by screws. Clamping collars 21 are installed with an interval of 1 m

Blocks measuring sensors (not shown in figure 2) are installed at certain intervals along the length of the line in accordance with predetermined levels of trawling towed the line in the water column. Housing units in width and thickness correspond to the dimensions of the fairing and not introduce significant distortions in the hydrodynamic characteristics of the tow line.

To enable the use of tow line on ships of various designs and sizes without special refitting of the vessel, reducing the area occupied space on the deck and reduce the time of setting/sampling tow line all equipment is placed in the container 22 (see Fig 3, 4), in which, in addition to the compartment for placement of equipment towed the line, provided the instrument compartment 23 for equipment acquisition and processing of measuring information.

As shown in figure 4, at the bottom of the platform 2 of the slip, by placing the intermediate section 3 globitel, set limit and 24, in the gap between them filled ribbon fairings 17 tow the line. The limiter 24 is made in the form of pillars, rounded from the factory tow line and gradually tapering towards its descent from a slip, forming arcuate leaf extension gap from 5 cm to 50 cm

Next to the platform 2 of the slip is set, the actuator 25 of the slip, providing the pivot lever 13 about the horizontal axis.

Plug the lead 10 with a connector 11 for fixing the pull end of the rope 16 tow line connected to the rotating support surface 6 (rol). The flange of the roll located at the level of the lower flange (cheeks) of the drum 1 towing winch, driven in rotation by the actuator 26.

The fixation device towed the line (see figure 5) contains the rack 8 in the form of a pipe, which is put on the rotating drum 27 from caprolon, fixed mounting rings 28, 29 are rigidly secured to the rack 8.

The drum 27 has an enclosure 30, forming two strands. In a narrow Creek, located between the enclosure 30 and the upper flange 31 of the drum, fixed pulling end of the cable 32. Next, the cable 32 passes through a block (pulley) 33, the yoke which is attached to the upper mounting ring 29, and through blocks 34, 35, shroud which is mounted on a strap 36 at the top of the rack 8, is put into the pipe, where the cover unit 37 is installed on the holder reguliruemym. Root end (loop) 38 of the cable 32 is fixed on the rod 36.

Adjustable cargo made in the form of a set of disks 39, attached to the rod 40 mounted on the lower supporting disk 41 of the cargo. For easy installation, decorative disks 39 are side undercuts 42. The top rack is made Luke 43 to install the disk 39 of the regulated cargo. Under the hatch 43 installed set screws 44 through which the load is suspended at the top of the rack 8.

To facilitate sliding of the cargo inside the rack 8 is installed rails 45 of caprolon.

In the broad stream of the drum 27, located between the enclosure 30 and the lower flange 46 of the drum, fixed pulling the end of a metal stretch belt 47, which, as shown in figure 4, covers towed the line, moving with her in the Creek drum 1 towing winch as grazing/styling turns towed the line. The second (root) end of the draw tape 47 mounted on a bracket rigidly connected to the fixed base 7 of the rotating supports.

To use the tow line the container 22 with its equipment installed on the stern of the vessel.

In the initial state of the towed line 15 with blocks measuring sensors placed on the drum 1 tugger winches and fixed stretch tape 47 fixation device. When this tape 47 is fully etched with a rotating drum 27, and SRAW is 32, holding the load at the top of the rack, placed in the upper stream of the drum 27. The position of the cargo fixed with locking screws 44.

Before setting towed line check whether the crimping force of the tension of the belt 47. To do this, loosen the set screws 44 and, if necessary, add or remove the necessary number of disks 39.

For setting the tow line 15 open door in the rear wall of the container 22. Include the actuator 25 of the slip, unwrapping the lever 13 downward, as shown in figure 3. Playground 2 slip is set in an inclined position and in turn drags globitel towed the line. Thus pivotally connected parts 3, 4 globitel revealed grating 4 tipped overboard and leads the first intermediate section 3, and then the leash 10 attached to its load-carrying fork cable 16 towed the line.

At the same time, including at low speed, the actuator 26 tugger winches, begin to protravlivat tow line 15, bring it to the limiters 24 and fill in the gap between them.

After immersion, globitel towing winch is switched to an operating mode in which it operates to the full release tow line drum 1.

When this cargo is released from the locking screws, pulling the rope, which begins to rotate the drum 2, and tension band 47 begins to gather around him as grazing orbits towed the line 15 from the drum 1 towing winch, compressing the ribbon fairings constant force and moving in with her in the stream of the drum 1. The bottom edge of the ribbon fairings slides on the rotating flange bearings 6 and so, with vertical deflectors, tow line is drawn through the limiter 24. After limiters, tape turns, falls flat on the ground slip and get away with it in the water under the weight of globitel and its own weight. Thus, in the process of setting and retrieval of the towed line 15 prevented the coup of its fairings and jamming on the drum 1 winch, twisting and breakage of the fairings.

At the end of the statement tow line tow winch off.

In the course of the vessel carried out a survey of the deep layers of the water space. Readings of the measuring sensors and devices are transmitted through cables 18 in the equipment installed in the instrument compartment 23 of the container where they are recorded and processed.

When manoeuvring the vessel towed the line is held in the gap between the stops 24, which due to the arcuate shape of his wings protect the fairing from fractures.

Upon completion of measurements for a sample of tow line include towing l is bedco. Ribbon fairings, passing through the limiter 24 is vertical and supported by the flange of the rotating support 6, is directed into the stream of the drum 1 and is wound on him layer by layer, row by row, alimama stretch tape 47. Constant efforts crimping is provided by the tension cable 32, which when etching the tension of the tape 47 begins to gather around the drum 27 by lifting upwards 8 hours. Through this prevents jamming of the fairings and damage to the tow line.

When out of the water leash 10 towing winch switch to slow speed and after raising the leash to slip out the ribbon fairings from a gap limiter 24. Then, after entering the slip of the intermediate section 3 globitel include the actuator 25 of the slip, unwrapping the levers 13 and setting up the platform 2 to the vertical position. The position of globitel on slip locks, installing the brackets 5 to the upper end of the platform 2.

Thus, the introduction of the fixation device towed the line of the proposed design allows you to improve the performance characteristics tripping device as a whole, preventing violations of the single-layered winding towed the line in the process of its installation on the drum towing winch and bleed with it, eliminating the possibility of damage b is ceremoy line during its immersion in water, and sampling on Board the vessel.

Industrial applicability of the invention is defined by the fact that the proposed design can be manufactured according to the above description and drawings from conventional materials used in instrument making, and used as part of lifting equipment to tow the line.
