Description

The utility model relates to the field of marine engineering, namely to launching devices (SPU) for towed underwater vehicles and can be used for launching, towing, lifting and storing towed underwater vehicles (BPA) from various carriers.

Known tripping device "System for launching and recovering underwater vehicles, notably towed underwater vehicles (System for launching and restoring underwater vehicles, in particular towed underwater vehicles)", patent for invention US 8967067, publ. 03/03/2015, for the automatic descent and lifting of marine vessels and underwater vehicles from a surface ship. SPU consists of a tilting composite hinge ramp, including the hull, side parts and towing devices, as well as to control the movement of the vehicle along the ramp during descent and the movement of the vehicle upward along the ramp during lifting. The ramp contains a movable support, which deviates between immersion in water and lifting in a horizontal position. The system includes floating means, which during descent allow the movable support to be on the surface or near the surface of the water. The lower part of the composite hinge ramp also has an external surface, which provides water flow around the form and the end part of the ramp and the reduction of vertical dynamic movements caused by waves.

The disadvantages of this device:

- there is no possibility of using this SPU in the dimensions of the container;

- BPA rise occurs from water, which greatly complicates its reception of SPU.

Known ship tripping device "Ship tripping device for towed underwater vehicles", patent for utility model No. 91968 RU, publ. 03/10/2010, containing a lodgement, a winch, a trolley mounted on a horizontal ceiling, with the possibility of its longitudinal movement and withdrawal beyond the aft section of the carrier object, a catcher (gripping mechanism) with the possibility of its rotation in a vertical plane in which through holes are made for the passage of the cable tug, guide and receiving rollers, rigidly mounted on the trolley without changing their height relative to the deck of the carrier object.

Known disadvantages of this device:

- SPU has a bulky and complex structure (especially demanding on the height of the room) and significant metal consumption in general;

- SPU is stationary, it is constantly installed at the facility; this design cannot be quickly removed from the carrier object and mobile delivered to another desired point.

A common drawback of these technical solutions is the lack of mobility of devices.

Known tripping device "Method and apparatus for deploying and recovering water borne vehicles (Method and device for lowering and raising watercraft)", patent for invention US 5253605, publ. 10/19/1993, in which the boat, when not in use, is stored in a portable standard container. The lower surface of the container contains many rollers that allow the boat to take the starting position (for descent) from the stowed position, while the nose of the boat is located on the rollers, and the back of the boat is located on the roller block, which is attached to the stern of the surface object using hinges carrier. The gantry crane, with its cargo cable attached to the nose of the boat, rotates the boat around the hinge so that the stern of the boat is submerged in the water for stability, and directs the boat backwards with the bow remaining in the air and the stern located in water, until the moment when the bow is already located above the water and is at a distance from the stern of the surface ship, and then, completing the descent, lowers the nose of the craft into the water.

The disadvantages of this device:

- there is no opportunity for the descent and towing of the BPA;

- there is no possibility of placing the cable tug in the container of the required length.

Also known hoisting device "Launching device", patent for invention No. 2585181 RU, publ. 02.16.2015, made mobile and placed in a rigid frame, which is taken as a prototype. The supporting base of the device is mounted on the horizontal supporting surface of the rigid frame. A connecting rod, pivotally mounted at one end on a support base, is provided with a rod connecting its free end to a pivot bearing pivotally mounted on the support base. The connecting rod drive is placed so that one end is connected to the support base, and the other end to the connecting rod. The lifting device is equipped with a lifting frame pivotally mounted on a rotary support. The lifting frame is equipped with a drive connected on one side to the pivot bearing, and on the other hand to the lifting frame. The lifting frame has at least one block and at least one roller interacting with a guide rail located on the vertical wall of the rigid frame from the side of the hoisting device.

The disadvantages of this device:

- there is no possibility for launching, lifting and towing towed underwater vehicles, including to capture the BPA and place it in a container;

- there is no possibility of placing the cable tug in the container of the required length;

- there is no possibility of placing the BPA in the container for storing in the field and its maintenance.

These disadvantages of the considered hoisting devices limit the possibility of their use.

The objective of the proposed technical solution is the creation of a mobile lifting device for a container-mounted BPA, which will ensure the possibility of its placement on a carrier object without conversion or with little interference in the construction of the object.

The technical result of the proposed solution is to increase the efficiency of using a lifting device for a BPA by ensuring its mobility, the ability to quickly install it on various carrier objects and transportation by various means of transport, as well as for storage and maintenance of a BPA.

The technical result is achieved in that the tripping device for towed underwater vehicles comprises a support base located in a rigid frame, a pivot support pivotally mounted on the support base, a lifting frame pivotally connected to the pivot support, a winch for winding the cable tug, drives, system management. The rigid frame is made in the form of a container in which a lodgement is mounted on the support base for placing the towed underwater vehicle in the marching position. In the upper part of the container are a cable layer and a guide roller. The winch is made of double-drum, while the drums contain sprockets covered by a chain on which the root end of the cable tug is fixed.

The axis of the lifting frame is rotatable in opposite directions and a gripping mechanism is rigidly placed in the middle of the axis, in which the towed underwater vehicle is held. The gripping mechanism is equipped with a freely rotating pulley. The cable tug passes through the cable layer, it goes around the guide roller and the rotating pulley. The second end of the cable tug is mounted on a towed underwater vehicle.

The main advantage of a mobile hoisting device over a stationary one is the ability to quickly deliver equipment to anywhere in the World Ocean due to the fact that several potential carrier objects are located in all water basins.

The essence of the utility model is illustrated by drawings, where:

- in FIG. 1 shows the proposed tripping device for towed underwater vehicles in the stowed position;

- in FIG. 2 (a, 6, c) presents the stages of deployment of SPU:

and - the beginning of the deployment,

b - the passage of the BPA and the capture mechanism in the alignment of the container gates,

c - completion of deployment of SPU;

- in FIG. 3 shows the proposed hoisting device in the operating position (the gripping device holds the PSU before the descent or before bringing the SPU to the stowed position).

The trigger device comprises a support base 2 located in the container 1, pivotally mounted on the support base 2, a pivot bearing 3, pivotally connected to the pivot bearing 3, a lifting frame 4 with a folding mechanism (not shown in FIG.), A double-drum winch 5, drives, a control system ( in Fig. not shown). In the upper part of the container 1 are the cable layer 6 and the guide roller 7.

In the container 1, a lodgement 8 is also installed to accommodate the towed underwater vehicle 9 in the stowed position. The winch 5 is made of double drum, while the drums contain sprockets covered by a chain 10 on which the root end of the cable tug 11 is fixed. The axis 12 of the lifting frame 4 is rotatable in opposite directions and a gripping mechanism 13 is rigidly placed on the middle of the axis 12, in which the towed underwater vehicle is held 9. The gripping mechanism 13 is provided with a freely rotating pulley 14. The cable tug 11 passes through the cable layer 6, envelops the guide roller 7 and the rotating pulley 14. The second end of the cable tug 11 is fixed on a towed underwater vehicle 9.

The lifting device is located, for example, in a standard 40-foot transport container. In the marching position, the BPA 9 is mounted on the lodgement 8 and is held in the gripping mechanism 13. The cable tug 11 coming from the BPA 9 covers the rotating pulley 14 and the guide roller 7 and, passing through the cable layer 6, is laid in one layer on the winch drums 5. The use of a double-drum winch allows for the placement of a cable tug of the required length in a standard container.

The lifting device operates as follows.

The proposed SPU, located in the container 1, is delivered to the place of use. Delivery of SPU to the installation site on the carrier 15 can be carried out by water, air transport and other methods. Next, the device is installed at the required place for work (open or closed deck) on the carrier 15 at a certain and sufficient distance from the aft section of the carrier 15 to ensure its safe operation, where it is brought into working position.

From the control panel, a signal is sent to rotate the winch drums 5, to etch the cable tug 11, to rotate the pivot bearing 3 and the lifting frame 4, and to rotate the axis 12 of the lifting frame 4. The pivot bearing 3 from a vertical position comes into horizontal, the lifting frame 4 is deployed in side of the stern of the carrier object 15, the axis 12 on the lifting frame 4 rotates (rotates in opposite directions) the gripping mechanism 13 with the BPA 9 in a position favorable for the launch of the BPA 9 into the water. After bringing the SPU to its working position by a signal from the control panel, the gripping mechanism 13 is opened and the BPA 9 is launched onto the cable tow 11 using a rotating pulley 14, a guide roller 7, a cable layer 6 and a double-drum winch 5.

The movement (kinematics) of the control system elements occurs synchronously, according to the working algorithm of the program embedded in the control system of the control system, which is loaded into the microcontroller of the control system module. Thereby, the necessary kinematics of the SPU is achieved, in which the BPA 9 together with the gripping mechanism 13, performing rotational-translational movements, leaves the container 1 without touching it.

The movement (programmed into the control system of the control system) of the rotary support 3, the lifting frame 4 and the axis 12 on the lifting frame 4 is carried out by drives (electric or hydraulic). Tracking the rotation of the axis 12 of the lifting frame 4 is carried out using rotation sensors. The extreme positions of the moving mechanical parts are monitored by limit switches.

The BPA is lifted to the carrier object and the SPU is brought to the stowed position in the reverse order.

The proposed design of the control system allows for the maintenance of the control unit in the container, for which it is necessary to detach the control unit from the gripping mechanism and bring the control unit into working position.

Thus, the design of the proposed technical solution has the following advantages:

- allows you to place the hoisting device in a standard 40-foot container, which ensures its mobility and the ability to quickly install it on various media without re-equipment or with little intervention in the design of the facility, as well as protection of SPU systems;

- allows storage of towed underwater vehicles in a marching manner and their maintenance.

The achievement of the claimed technical result is confirmed by calculations and computer simulation of the interaction of the launching device, container, towed underwater vehicle and the carrier object.
