Description

A mobile hoisting device of a modular type, designed for setting up and retrieving a towed line, with the ability to be placed on almost any vessel. The invention relates to devices that provide descent, ascent and towing of a line consisting of a load-carrying cable, sealed cables, sensors located along the length of the line, fairings and a recess at the end of the line. The invention can be used for installation on ships, including where dismantling deck mechanisms is impractical and the location of the ship's superstructures does not allow the use of a conventional container with a launching device, for examining horizons in the water column, measuring the physical parameters of horizons, and transferring the latter for processing and calculations .

The invention makes it possible to place a mobile launching device of a modular type on almost any vessel, due to the modular design of parts of the mobile launching device and placing the modules at a distance from each other.

The advantages are achieved by making parts of the mobile lowering device in the form of modules, which allows, if necessary, to place the modules of the rotary support (slip) and the winch with a drum at a convenient distance, without placing modules on hatches, without blocking passages, without dismantling deck structures and mechanisms.

TECHNICAL FIELD

The present invention relates to the field of marine technology, namely to mobile launching devices for towed lines and underwater vehicles. The technical solution can be used on ships for launching, towing, lifting and storing towed lines used for hydrophysical research. Specifically, the proposed technical solution relates to hoisting and hoisting devices that provide installation and retrieval of towed lines containing blocks of measuring sensors distributed along the load-carrying cable, on sealed cables passed through holes in detachable fairings, and a deepener (underwater vehicle) containing hingedly connected grids depth wings and float section.

Hoisting devices for towed lines are a widely used technique. Such devices are in demand in various industries, for example, when studying physical processes in water bodies and searching for sunken objects.

One of the complex technical problems is the placement of a mobile container with a lifting device on a carrier vessel. As a rule, a standard 20-foot or 40-foot sea container is used. The container contains a winch with a drum, a device for fixing the line on the drum, a control system and a rotating device with a frame (slip), on which the deepener or underwater vehicle is located “in a traveling manner.” However, not on every ship, due to the presence of superstructures and deck mechanisms, it is technically possible to place a mobile container (especially a 40-foot one) in a convenient place on the deck. It is required to specially equip the place on the deck of the ship, and dismantle deck mechanisms: winches, searchlights, pumps, fences, weapons, etc. The mobile container occupies a passage along the deck of the ship, closes hatches, signal lights, and creates an obstacle to the movement of the crew, especially in an emergency situation.

The proposed technical solution allows you to place a mobile launching device of a modular type, both in a container and in a modular version - in two small containers or openly on the deck of any vessel, since the modules are smaller in size compared to a standard container and can be installed with a significant distance (0.5-6 meters) from each other. This makes it possible not to install modules on hatches in the deck, not to dismantle deck mechanisms, but to place modules between them, and with some (up to 10°) axial displacement of the modules.

The proposed technical solution is implemented through the modular design of the hoisting device.

BACKGROUND OF THE ART

The design of a hoisting and hoisting device for towed underwater vehicles is known (utility model RU No. 191507). The device contains a support base placed on a rigid frame in a container, a rotary support pivotally mounted on the support base. A lifting frame pivotally connected to a rotating support and a folding mechanism; winch with two drums, control system. The underwater vehicle is held on the axis of the lifting frame using a gripping mechanism.

According to the authors of the invention, when placing the hoisting and hoisting device in a container, the efficiency of using the hoisting and hoisting device increases due to the possibility of quick delivery and placement of a 40-foot container with a hoisting and hoisting device on a ship located in any geographical location. It should be noted that the decision to place a lifting device in a container existed long before the appearance of the technical solution in question, and if such a container with a lifting device is possibly mobile in terms of delivery, for example, on a container ship, then installing a container with a lifting device on any ship represents complex technical problem. There may not be space on the ship to install a standard container on deck without dismantling deck mechanisms: winches, bollards, fencing and other equipment. Being placed on the deck, the container closes hatches and passages and creates difficulties for the movement of crew members, especially in an emergency situation.

The design of a hoisting and hoisting device is known (patent RU2585181), containing a support base, a rotating element pivotally mounted on the support base, a connecting rod with a drive, and a number of interconnected mechanical elements placed in a mobile container, which, according to the authors, is the novelty of the proposed technical solution and mobility is achieved. It should be noted that placing all functional parts of the hoisting device in a container is a widely used practice.

The problem that the known invention solves is the creation of a mobile launching device that can be quickly delivered, installed and deployed on a ship, brought into operational condition, and then could be rolled up into a container and promptly moved to another location.

In the invention under consideration, there is a problem of installing a mobile container on the deck of a ship, which is not intended to accommodate extraneous cargo and structures, such as containers. Visibility is impaired, signal lights and deck markings are covered, hatches and passages are blocked, and, as a rule, the dismantling of deck equipment: winches, fences, etc. is required.

A hoisting device for setting up and retrieving a towed line is known (RU patent No. 2339536). In the aspect of the proposed invention, this technical solution is considered as a prototype. The hoisting device of the towed line is installed on a rigid base placed in a container. The SPU contains: a rotary support, with a frame and a towed line deepener mounted on it “in a stowed manner”; a drive that moves the rotary support; towing winch, with a horizontally mounted drum, and a drive, for multi-layer single-row winding of the line; drive control systems. A device for fixing a line on a drum, in the form of a hollow column placed between the rotating frame and the drum, a rack on which the rotating drum is mounted. The drum has grooves for laying the tension tape covering the towed line on the winch drum, with the ability to move in the grooves of the drum as the turns of the towed line are released and wound, and grooves for laying the cable connected through a system of blocks with an adjustable load moving inside the rack.

The disadvantages of this solution are: the extreme complexity of the design that ensures the fixation and clamping of the line on the drum, the lack of compactness in the placement of the elements of the device and the placement of all functional parts of the hoisting device in one container, which is also difficult to place on the deck of the ship without dismantling the deck mechanisms and special preparation of the site placement.

PROBLEMS TO BE SOLVED

The problem solved when implementing the proposed technical solution is to ensure the installation of a mobile launching device on the unequipped deck of almost any vessel, due to the modular design of parts that are relatively small in size, and the ability to adjust the distance between the modules, in the range of 0.5-6 meters, bypassing at the same time, hatches, deck mechanisms, elements of hull structures, leaving space for the crew to move. At the same time, all components of the SPU are purposefully arranged to allow modular placement. For example, a compact device for fixing a line on a drum, equipped with a pressure tape made in the form of a flexible rope, with rectangular non-metallic plates placed along the entire length, is located in the drum module with a winch and keeps the line from sagging between the modules when setting up the line and tightly wound on the drum when sample. The modules were purposefully created, as a result of which the SPU acquired a new property: separate placement of modules, while maintaining all operating functions.

DISCLOSURE OF THE INVENTION

The proposed technical solution formulates the main distinctive features of a hoisting device for a towed line.

A mobile hoisting device of a modular type for setting up and retrieving a towed line, containing a support base placed on a rigid frame, a rotary support pivotally mounted on the support base, a lifting frame with a folding mechanism (slip) pivotally connected to the rotary support, a towed deepener placed on the frame in the "" position in a marching way"; a device for fixing the line on the drum, with a stand on which the drum is mounted, with the possibility of rotation; a tape in the form of a flexible rope covering the towed line, with rectangular non-metallic plates installed along the entire length, and having the ability to move in the grooves of the winch drum as the line is set up/retracted; winch with a drum, with multi-layer single-row winding of the towed line; drives; a control system, characterized in that the rotary support and winch with a drum are placed separately on support bases, in modular structures that can be placed on the deck of a vessel with the modules removed from each other.

Feature: “a rotary support and a winch with a drum are placed separately on support bases, in modular structures that allow placement on the deck of a vessel with the modules removed from each other” allows modules to be placed on the deck of a vessel without blocking hatches and passages, and without dismantling equipment and deck mechanisms, at an adjustable distance (0.5-6 meters between modules).

Sign: “the device for fixing the line on the drum is made in the form of a rack on which the drum is mounted, with the possibility of rotation, the pressure tape is made in the form of a flexible cable, with rectangular non-metallic plates installed along the entire length, covers the towed line on the winch drum, has the ability to move in grooves of the winch drum and is wound/unwound on the stand drum as the line is set up/retrieved", allows you to make the fixing device compact for combining into a module, and keeps the line from sagging between the modules when setting up the line and tightly wound on the drum when picking up, at a distance between modules up to 6 meters.

The implementation of the invention makes it possible to simplify the placement of the hoisting device on the ship, and to perform the installation without dismantling structural elements and deck equipment, to ensure fixation and compression of the line on the drum, preventing sagging of the line between the modules when setting up the line, and to ensure tight winding of the line onto the drum when retrieving, taking into account the increased distance between modules.

The claimed technical solution is proposed as a result of a targeted improvement of the SPU, reducing its size for the purpose of compact design, and possible modular placement. For example, for the slip module, a gearbox with a vertical engine is used. In the module with a winch and a drum, the design of the device for fixing the towed line on the winch drum has been improved.

In known technical solutions, the problem of modular placement was not posed or solved. Moreover, the layout of known SPU devices often exceeds the dimensions of the container, for example, that of the prototype. Due to the modular solution and improvement of the fixation device, it became possible to place modules at a distance of up to 6 meters, while ensuring line tension during sampling and no sagging during bleeding. Thanks to the use of well-known engineering solutions, it became possible to separate, modular placement of SPU, and the total linear size of two compact modules is less than a typical 20-foot sea container. Modular placement simplifies loading and unloading and placement on the ship's deck. Installing a 20, and even more so a 40-foot container on a ship without preparation is a complex technical problem. Installation on most ships, without retrofitting and dismantling deck mechanisms, of such containers is simply impossible, or is associated with a significant amount of work, which calls into question the reality of the stated goal - mobility, specified in known technical solutions. The proposed technical solution is simple to implement, and its application does not clearly follow from the prior art for a specialist and is not based on changes in quantitative characteristics. Due to a special modification of the locking device, the hoisting device is purposefully arranged in modules that allow separate placement at a distance and with axial displacement. Therefore, the proposed modular design of the SPU has a new property: the ability to be placed on the deck of almost any vessel without dismantling deck devices. Consequently, the claimed technical solution meets the criterion of “inventive step”.

The proposed technical solution makes it possible to use the SPU on almost any ship, which was impossible when placing the entire SPU, only in a container version. Therefore, the proposed technical solution meets the “novelty” criterion, because has distinctive features from the prototype, a new design of elements and new connections between elements. The given new properties of the proposed technical solution do not coincide with the properties that are distinctive features in known solutions, and are not the sum of their properties, which allows us to consider the proposed solution to meet the “significant differences” criterion.

IMPLEMENTATION OF THE INVENTION

A mobile hoisting and hoisting device for a towed line (Figure 1) contains: a support base 1 placed in a container, a recess 2,4,5, on a rotary support of the slip 3; rotary axis of the slip 8, line fixation device on the drum 7, winch drum of the line 9, winch motor 10, winch gearbox of the line 11, slip gearbox 12, motor 13. The SPU is placed in a container and therefore a number of technical problems arise for installation on the deck of a ship. The container doors must be located at the side of the vessel so that it is possible to place the rotary support of the slip 3, with a recess 2,4,5 above the water.

A modular type mobile hoisting device (Figure 2) consists of two modules: a slip module a), and a winch drum module b), with a line fixation device on drum 7. The proposed implementation of the SPU allows the modules to be placed on the deck of almost any vessel, due to the increase or By reducing the distance between modules, hatches or deck mechanisms can be passed through, and the modular placement allows some (up to 10°) axial displacement.

The line fixation device on the winch drum (Figure 3) contains: winch drum 9, pressure tape 14, fixation device frame 15, pressure tape drum 16, load in the raised position 17, load in the lower position 18 (the line is etched), limit switch 19 , hand winch 20. Limit switch 19 is activated when the load reaches the bottom position. Manual winch 20, designed for lifting loads during repair and maintenance. The fixing device 15 has a frame structure to facilitate maintenance and visualization of operation. The pressure tape 14 is made in the form of a rope passing through holes in plastic rectangular elements located along the entire length of the rope. Moreover, the plastic elements have gaps between adjacent elements and are in close contact with the line. This design of the pressure tape allows the line to be placed on the drum with a tight fit when picking up the line and to eliminate sagging during etching. When setting - selecting a line, the size of the line placed on the drum changes, the diameter of the wound line on the drum changes, and the required value of the tape tension force changes accordingly. To compensate for the change in force, force is transmitted to the tape covering the line on the drum through a cable with a load, which moves down when installing the line, and up when picking up the line. When the load is in the lowest position, limit switch 19 is triggered, which signals that the line has been completely withdrawn. Making the tape 14 in the form of a flexible rope with plastic elements (for example, made of caprolon) allows you to press them tightly against the plastic floats of the line (also made of caprolon), ensuring their tight pressing, ensuring tight winding of the line, and eliminating sagging of the line during installation.

The device of the deepener in the position immediately before installing the line, after turning the rotary support of the slip 3, is shown in Figure 4. Here: 1 - the support base of the slip, 2 - the lower part of the deepener with the float part, 4 - the articulation of the parts of the deepener, 5 - the upper part of the deepener, 8 - rotary axis of the slip, to which the drive torque is supplied. The rotary axis 8, rotating, moves the rotary support 3, with the frame and recess 2,4,5 installed on it. The design of the deepener has hinged, articulated parts, a frame 4 and a float section 2. The purpose of the float section 2 is to hold the line at depth during towing and ensure its stability.

After turning the axis 8 by 150°, the movement stops, the winch drive of the drum 9 is turned on, the holders on the frame of the rotary support of the slip 3 are opened. The deepener 2,4,5, with line 6, begins moving to the required depth.

The mobile launching device, in 3-D image, is shown in Figure 5. The mobile launching device is located in a container, which takes up a lot of space on the deck.

A mobile hoisting and hoisting device of modular design is shown in Figure 6. The modules of the mobile hoisting and hoisting device, due to their compact placement, have dimensions smaller than those of a standard container, and due to their modular design, they are placed at an adjustable distance, with the possibility of axial displacement, passing hatches and bypassing deck mechanisms. At the same time, a compact device for fixing the line on the drum is located in the drum module with a winch and keeps the line from sagging between the modules when setting the line and tightly winding onto the drum when retrieving.
