Description

The utility model relates to the field of shipbuilding and ship repair, and in particular to devices for moving along rail tracks located at the mark of the territory of the shipyard, blocks, modules and ships in both longitudinal and transverse directions. The utility model is intended for use as ship equipment for shipbuilding and ship repair enterprises, and can also be used in other industries when moving heavy cargoes (metallurgy, railway transport, aircraft manufacturing).

In the shipbuilding and ship repair enterprises of Russia, in the vast majority of cases, classic ship trains consisting of ship bogies moving on rails only forward or backward are used to transport ships across the territory of the enterprise. To change the direction of movement by 90 °, as a rule, a transborder is used. In addition to using the transborder, it is possible to change the direction of transportation by transferring the vessel to carts installed on perpendicular tracks.

The main problem of such enterprises is the high complexity of work when changing the direction of movement of the transport system with the structure installed on it.

In modern foreign shipyards and some domestic shipbuilding systems for ships with slewing bogies have become widespread. Using transportation systems of ships of this type allows you to abandon transborders or transplant operations, thereby reducing capital costs for new construction or overhaul of shipyards.

As a prototype, a well-known modular transport system for moving ship structures was selected (patent RU No. 129076, B63C 5/00, B63B 9/06, B63B 9/06, 01/23/2013), which to some extent solves the described problem. Thus, a modular transport system for moving ship structures is made in the form of a self-propelled rail ship train moving along rail tracks and consisting of driven and non-driven slipway bogies connected by a box-shaped load-bearing keel block. In this case, the bogies are equipped with transport modules, each of which consists of a pair of four-wheel drive or non-drive ship bogies fastened together by connecting rods, and the number of modules is determined by the weight of the ship structure, and the length of the connecting rods ensures that adjacent carts are placed at a distance equal to the distance between adjacent rows of transverse paths, and all modules of the ship train are controlled by a hydraulic system from a common mobile pumping station. To turn the trolleys, the transport system with the load moving along the transverse paths must be stopped at the point of transplantation on the path perpendicular to the direction. The hydraulic jacks of the trolleys are lowered until the wheels come off the surface of the rail tracks and lift them to the height necessary to turn the trolleys. The turn is carried out using the mechanisms of rotation of the trolleys, for which the transport system is installed on the supporting surfaces of the keel block beam. After the bogies are turned, the hydraulic jacks rise to the height at which the transport system with the cargo is transported.

The main disadvantage of the prototype is its specificity, since its structure includes a special keel block beam, without which it is impossible to turn the carts. Thus, the prototype can not work with other sap beams, which makes it not universal. In addition, the presence of a keel block beam, which is connected to hydraulic jacks, complicates the entire structure, making it more bulky and inconvenient to operate.

The task to which the claimed utility model is directed is to create a modular transport device for the longitudinal and transverse movement of ship structures of various dimensions, which allows to achieve the following technical results.

Technical results achieved using the claimed utility model:

- improving ease of use;

- expansion of the arsenal of technical equipment intended for the longitudinal and transverse movement of ship structures of various dimensions.

Technical results are achieved due to the fact that in a modular transport device for moving ship structures made in the form of a self-propelled ship train, consisting of a hydraulic pump station and at least four rotary slipway bogies, each of which is equipped with a load lifting / lowering mechanism and is connected with a hydraulic pump station, each rotary slipway trolley is equipped with an auxiliary hydraulic cylinder designed to raise / lower it, and a hydraulic pump station tion is provided with a control system based on programmable logic controller.

As a mechanism for raising / lowering the load, a hydraulic cylinder can be used.

The hydraulic pump station can be equipped with swivel wheels.

The hydraulic pump station can be equipped with two pairs of wheels, the first pair of wheels can be installed perpendicular to the second pair of wheels and equipped with an extension mechanism.

Each swivel stacking trolley can be equipped with a hydraulic movement panel.

Each swivel stacking trolley can be equipped with a hydraulic panel for lifting / lowering the load.

Each swivel stacking trolley can be equipped with a hydraulic panel for raising / lowering this trolley.

Each swivel stacking trolley can be equipped with a balancing axis.

The claimed modular transport device for moving ship structures contains rotary drive berths with hydraulic drive, which move on rails. At the same time, the carts included in the inventive modular transport device, due to the presence of a 90 ° rotation unit, allow you to change the direction of movement, which in turn allows you to refuse to use a transborder or perform the operation of transferring a vessel to carts installed perpendicular to the tracks, which means improves the usability of the claimed technical solution.

The number of trolleys can vary from 4 (2 pairs) to 24 (12 pairs) or up to 100 (50 pairs). Depending on the mass and size of the product being moved, the number of pairs used can be increased by the required number of times and can exceed 50 pairs.

Each rotary slipway trolley includes a load lifting / lowering mechanism and an auxiliary hydraulic cylinder designed for raising and lowering it. It is advisable to use a hydraulic cylinder as a mechanism for raising / lowering the load, however, other mechanisms can be used to perform this function. In this case, each trolley can be equipped with two separate hydraulic cylinders - one for raising / lowering the load and the second for raising and lowering the trolley itself, and can be equipped with a combined hydraulic cylinder, which will include both a hydraulic cylinder for raising / lowering the load, and a hydraulic cylinder to raise / lower the trolley itself. The use of one common hydraulic cylinder simplifies the design; therefore, it is preferable to use a combined hydraulic cylinder. Nevertheless, a variant with two hydraulic cylinders is also possible, which is distinguished by reliability and ease of maintenance.

The claimed design of the rotary stacking carriage enables it to be raised above the rails to rotate by 90 ° and further lowered onto the rails of the transverse direction without dismantling the hydraulic line and without the presence of additional elements, such as special keel blocks. Consider the design of the prototype, which consists of modules, which include a keel block beam and two trolleys. In this case, the trolleys are fixed on the beam. To rotate 90 °, it is necessary to descend onto the supports integrated into the beam, raise the trolleys above the rails and turn them by the rotation mechanism located in the beam. It turns out that the prototype can only work with specialized nodule beams. Unlike the prototype, the claimed technical solution does not have a special keel block beam, and the possibility of turning the trolleys is achieved due to the presence of auxiliary hydraulic cylinders, which, if necessary, raise the trolley above the slipway, and thereby provide the possibility of its rotation manually or automatically. Thus, the inventive modular transport device can be used to move any goods and is compatible with any keel block or other beams, which makes it universal and more convenient for use.

Auxiliary hydraulic cylinders are mounted on slipway trolleys in such a way that, resting on the slipway field, lift the trolleys to rotate them. To achieve this goal, it is advisable to place auxiliary hydraulic cylinders in the lower part of the stacking bogies, since this arrangement is optimal in this case. In addition, it is advisable to provide auxiliary cylinders with stops that are capable of providing a sufficient contact area of the auxiliary hydraulic cylinder with the slipway. In other words, the stops will ensure the stability of the trolley during its lifting and prevent damage to the slipway at the turning point. The stops can be equipped with integrated thrust bearings.

To ensure the possibility of moving the rotary stacking carriage, it is proposed to equip it with a hydraulic drive, for example, a hydraulic motor with a planetary gearbox.

When equipping rotary stackable bogies with additional hydraulic centering devices, the claimed technical solution will allow for large-block assembly of block sections with positioning along six axes, which will undoubtedly increase the usability of the claimed device.

The hydraulic pumping station is a chassis on a pneumatic passage or railway wheels with a hydraulic drive of movement, on which hydraulic units and a control panel are installed, ensuring the operation of the modular transport device in all modes.

All rotary stackable bogies are connected by hydraulic hoses of high pressure to the hydraulic pump station. In addition, all hydraulic actuators are connected to the hydraulic pump station through high pressure hoses. The hydraulic pumping station, in turn, feeds the trolleys through the high pressure hoses and controls them. In addition, the hydraulic pumping station provides the following functions: soft start, movement and dynamic braking of the modular transport device; trolley speed synchronization; the work of the executive bodies, regardless of the number of pairs of bogies that make up the modular transport device, and the actual load on the bogies; power supply of hydraulic centering devices for large-block assembly.

The hydraulic pump station is equipped with a programmable logic controller, which is part of the control system. The specified programmable logic controller is designed to adjust, control and maintain the configured parameters of the modular transport device. So, in particular, the presence of a programmable logic controller allows you to perform the following functions:

- emergency shutdown of the system in case of exceeding the specified parameters of the modular transport device;

- data entry and setting the necessary parameters for the operation of a modular transport device in all modes by the operator on the display of the control panel;

- control of all parameters (pressure, temperature, etc.) in all modes with the display of parameter values on the display;

- manual switching of the operating modes of the modular transport device from the control panel;

- synchronization of the speed of movement of carts;

- locking the system after storage of the modular transport device at a negative ambient temperature;

- shutdown the system in the case of heating the working fluid to a temperature exceeding the permissible;

- automatic cooling of the working fluid at a temperature exceeding the set.

It is worth noting that, due to the presence of a programmable logic controller, the operator can set various modes of operation of a modular transport device from the control panel, which greatly expands the potential for its use and gives it universality. So, in one mode, all the piston cavities of the load lifting / lowering hydraulic cylinders within each zone can be interconnected, while the pressure in the hydraulic cylinders is equalized, and the same load will act on each trolley within each zone. In another mode, the lifting of all zones can be carried out simultaneously. In the third mode, the piston cavities of the load lifting / lowering hydraulic cylinders included in one zone can be interconnected, and the piston cavities of the other zone can be independent. The fourth mode can allow the lifting of any individual beam mounted on two trolleys, regardless of the remaining beams. There can be many such modes - depending on the characteristics of the load and the area of use of the claimed device.

Thus, the programmable logic controller allows the operator of the hydraulic pump station to remotely monitor and control all the parameters of the elements of the modular transport device. Given that at the moment the control systems of other hydraulic pumping stations do not contain such controllers, but are made using other technologies, the claimed technical solution can be considered the most convenient, technologically advanced and safe among analogues.

The hydraulic station also contains a pump unit designed to supply the working fluid to the system and create the necessary working pressures and expenses in it, as well as a working fluid cooling system consisting of a forced air cooling heat exchanger with a discrete temperature sensor installed.

To further enhance the convenience of using the inventive modular transport device, the design of the hydraulic pump station can be performed in such a way as to allow this pump station to move along the rail in both longitudinal and transverse directions, that is, the hydraulic pump station can be made rotary, as and slipway trolleys. Changing the direction of movement of the hydraulic pumping station by 90 ° can be carried out both by making its wheels rotary, and by using a second pair of wheels located perpendicular to the first pair of wheels, moreover, one pair of wheels must be made to extend.

For the convenience of operation and operation, high pressure hoses can be equipped with quick-disconnect couplings, which allow quick connection or disconnection of lines without loss of working fluid.

The claimed technical solution can be additionally equipped with hydraulic panels for moving, lifting / lowering the load and raising / lowering the trolley itself, mounted on rotary stacking trolleys. The indicated hydraulic panels are intended for manual control of the operation of the cart drive and the process of raising / lowering the load, as well as the cart itself. Thus, in an emergency or just if necessary, the operator can manually control the rotary slipway trolley, which increases the usability of the entire technical solution.

To ensure the operation of the claimed modular transport device on worn tracks or tracks that do not comply with GOST, a balancing axis may be provided in its design. The balancer axis is a monolithic beam of variable cross-section, at the ends of which idle wheels of the slipway trolley are installed. The balancing axis, in turn, is mounted on the swing axis, which gives the balance axis one limited degree of freedom - swing in the vertical plane relative to the horizontal longitudinal axis of the trolley. The range of angular movement of the balancing axis in the general case should be at least 1 °, which allows even on tracks that do not comply with the applicable regulatory documents, all wheels (including the wheels of the drive axis) to have constant contact with the rails, which in turn ensures uniform transfer of load from cargo weights through all wheels on rail tracks. Thus, due to the presence of the balancing axis, the claimed modular transport device can work on worn tracks or tracks that do not comply with the "Rules for the design and safe operation of ship and ship equipment" 741-12-330-75, which makes the claimed technical solution universal and makes it the most convenient in operation on old not modernized tracks.

Swivel stacking bogies can be connected in two longitudinal lines by means of inter-body connections, for example, connecting rods. These connections are used to connect adjacent bogies with each other in order to maintain their relative position and stacking of high pressure hoses.

The structure of the claimed modular transport device can be integrated with a "cold start" system, equipped with a sensor for monitoring the temperature of the working fluid and intended for pre-heating the oil in the cold season.

The claimed technical solution can be applied as a complete set, or split into smaller modules for transporting orders of smaller overall dimensions.

According to the figures, the modular transport device for moving ship structures contains a hydraulic pump station 1 and a set of rotary slipway bogies 2, which are interconnected in two rows by connecting rods 3. Each rotary slipway trolley 2 is connected to the hydraulic pump station 1 with a high pressure sleeve 4, which equipped with quick detachable connections. On the trolleys 2 transverse and longitudinal podkilnye beams 5 are installed, designed for installation of the vessel.

Each rotary slipway trolley 2 contains a base 6 (frame) with a platform 7 on which a hydraulic panel 8 for lifting / lowering the load and a hydraulic panel 9 for movement are fixed. Also, the rotary stacking carriage 2 contains a combined hydraulic cylinder, which consists of a hydraulic cylinder 10, designed to raise / lower the load, and an auxiliary hydraulic cylinder 11, which is designed to raise and lower the trolley itself. The hydraulic cylinder 10, designed for lifting / lowering the load, is equipped with a transport support 12. The auxiliary hydraulic cylinder 11 is equipped with a stop 13. In addition, four wheels 14 with power flanges, a drive 15 and a balancing axis 16 are fixed on the base.

The hydraulic pump station 1 is made in the form of a base with a chassis on which removable casings 17 are mounted, under which an engine 18, a hydraulic tank 19, a cooling unit 20 and a hydraulic unit 21 are mounted. Also, an operator’s cabin (platform) 22 with a control panel is mounted on the base.

The hydraulic pump station 1 is equipped with a control system based on a programmable logic controller.

A modular transport device for moving ship structures works as follows.

The vessel is placed on the quench beams 5, and it can be any quench beams, since the claimed device is not limited to the ability to work with any particular type of beams. To move the vessel, a so-called self-propelled ship train is formed, which consists of a hydraulic pump station 1 and two rows of rotary slipway bogies 2, which are interconnected by connecting rods 3.

Using a hydraulic pump station 1 and drives 15 of the stacking bogies 2, a self-propelled ship train is delivered under the sodding beams 5. After that, the hydraulic cylinder 10, designed to raise / lower the load, begins to move the transport support 12 vertically up until it contacts the keel beam 5. After the contact of the transport support 12 with the keel beam 5, the hydraulic cylinder 10 continues to raise the transport support 12 higher, while also raising the keel beam 5 with the vessel installed on it. The hydraulic cylinder 10 is controlled from the control panel using a programmable logic controller through high pressure hoses 4.

As soon as the transverse keel beam 5 rises to a height of at least 50 mm and does not touch the platform, its lifting stops, and the height is fixed by the hydraulic cylinder 10. Thus, the sap beams 5 with the vessel on them are in an elevated state on the transport supports 12 of the stacking bogies 2 .

When you turn on the drives 15 of the stacking bogies 2 self-propelled ship train with a ship installed on it starts moving along the rails of the stocking field. Monitoring and control of the movement of slipway bogies is carried out from the control panel of the hydraulic pump station 1 using a programmable logic controller.

To change the direction of movement of a self-propelled ship's train from longitudinal to transverse, it is necessary to lower the transported object so that the supports of the transverse beams reach the level of the slipway. This is achieved by reducing the transport supports 12 with hydraulic cylinders 10. After that, auxiliary hydraulic cylinders 11 for raising / lowering the bogies are activated - they lower vertically until the stop contacts the slipway, after which the trolley 2 rises above the slipway. After raising all the trolleys above the rails, the operator manually or automatically rotates each trolley 2 90 ° to move to perpendicular rails. As soon as all the carts 2 are turned upside down, the auxiliary hydraulic cylinders 11 lower the carts 2 onto the rails. The control of auxiliary hydraulic cylinders 11 is carried out from the control panel using a programmable logic controller through high pressure hoses 4.

Such a mechanism for raising / lowering the stacking bogies 2 allows the claimed technical solution to be applicable in various areas of production, since its design does not depend on the load or on the platform on which this load is installed, the bogies are rotated independently and are not connected with the shape or material of the load and beams . Moreover, the proposed design is safer and more convenient to use.

After changing the direction of movement of the bogies, the hydraulic cylinders 10 again raise the beams with the load on the transport supports 12 and the movement of the load continues.

In addition, when the bogies are rotated, a similar rotation of the wheels of the hydraulic pump station 1 occurs for its further movement in the perpendicular direction.

If there are defects on the tracks or if the tracks do not meet all the requirements, the balancing axis 16 allows the trolley to have constant contact with the rails.

A hydraulic pump station with a programmable logic controller, hydraulic lifting / lowering panels and hydraulic movement panels can be used to expand the functionality of ship transport systems based on fixed non-powered and driven ship carts.

The claimed technical solution eliminates all the disadvantages that are available in analogues and, in addition, is quite simple to manufacture and convenient to use.

In a modular transport device for moving ship structures traditional structural materials are used, and it can be manufactured in experimental or mass production.

As part of the R&D of Technoros OJSC, a prototype of a swivel trolley and a stand for functional testing of experimental and serial products were manufactured. Functional tests of the prototype trolley were successfully carried out in May 2016.
