The invention relates to a device for offshore loading or unloading of vessels.

When you want high performance in high-speed freight, loading and unloading of vessels of special importance. To minimize costs, it is desirable minimum idle time, which is achieved only at high speeds reloading (transshipment) of bulk cargo.

In order to achieve the desired profitability or increase created cargo ships large capacity, has the appropriate dimensions. Sometimes the depth of water in the Parking lot of ships in ports is insufficient for the precipitation of these ships, or near deposits of bulk material is not any port, resulting in the alternative is the reception and dispatch of goods on the roads. However, offshore loading on the vessel assumes the existence of some distance from the shore berth for vessels and appropriate supporting structure for the conveyor means. In the past this close to shore for ships was created berthing piers, made of massive concrete platforms, which could move rail or pneumatic transport. Usually these massive concrete platform rested on pile foundations.

Described the RAID apparatuses have the disadvantage that they to the to in a constructive plan, and in terms of their manufacture, are relatively expensive, especially as the concrete works mostly have to be done locally, i.e. on the RAID. The cost of the large number of pile foundations.

The objective of this invention is to provide a device for offshore loading and unloading of ships, which eliminates the above disadvantages.

This task is solved by the device according to claim 1, having a steel bridge mounted on the head elements (mainly concrete heads) small number of separate pile foundations and with the possibility of longitudinal movement is one or more ship loaders or ship unloaders. Each pile Foundation includes a group of several individual properly installed piles hammered into the seabed and the upper ends of which are connected above the water with the head element, for example, concrete. Steel bridge is mainly in the form of multi-span beams with large spans, in particular lattice structure. Steel bridge, even if it is made in the form of a continuous structure or box girder, gives some economic benefits. Steel bridge can easily be in whole or in part transferred to the site and assembled there in the bridge with a large the spans. This bridge is equally serves as a pier for mooring vessels and supporting structure as to be moved in the longitudinal direction of the ship loader and/or unloader and conveyor located along the entire length of the bridge. At the same duty steel bridges of multi-span beams, for example, in the form of curved beams with a large distance between the upper and lower zones, i.e. in the form of beams with a large height can be built much lighter and with a much larger footprint than concrete or reinforced concrete bridges. Therefore, there can be reduced the number of pile foundations, resulting in further cost reductions. Steel bridge can be designed so that the upper belt relative to the water level inexpensively installed higher than in massive concrete structures, so that the portal ship loader or unloader ships with a corresponding bolt ran a small height. Again, this is advantageous from the viewpoint of reduction of the wind load on the wheel.

In principle, this bridge can be installed as a ship loader and ship unloader, however further described in detail only ship loader. Ship loader, in particular, may be pointing device with p is Loy, formed by itself is hard, straight horizontal beam moving in the direction transverse to the longitudinal axis of the loaded vessel and its own crane paths, and also based at least on its upper side and the lower side between the support rollers. The name "coordinate device" due to the fact that the head of the boom (discharge head) as a result of longitudinal movement of the ship loader on the steel bridge moves in one direction, and in another, in this case perpendicular to the coordinate moves through the nomination or movement of the boom. Thus the head of the boom can reach any point over all open cargo hatches of the vessel.

Preferably, the boom was moving in the longitudinal direction, i.e. moved or rotated, the counterweight, which, in particular, could rely on the rollers or wheels mounted on a common shaft, and which through the gear of different diameter, included respectively in engagement with the racks or tsevochnye teeth could move in the direction of the arrows. The relative sizes of the gear determines the path of reciprocal movement of the counterweight in relation to the trajectory of the arrows, so that when the extension boom in the appropriate proportions in FR the opposite direction whereby the counterweight. Along with the described solution for the mechanical force of the drive through the gear and rack or similar means, operating safely in the Maritime environment, the counterweight can be moved and with additional electrical, hydraulic, pneumatic or other mechanical means, which, however, in this case, because of the need for a separate control, management and the presence of drive elements require in comparison with a mechanical forced coupling of the additional costs.

Further preferably, the boom of the ship loader had on its front free end of the vertical lifting, boot tray, mainly consisting of the upper discharge chute, telescopic discharge tube and the guide frame, which is then mostly placed inside the pylon. For the lower end of the telescopic discharge tube may be further provided stepwise device. The pylon is equipped with lifting devices, with which the input tray and the guide frame may be raised or retracted upwards, so that the drawer could reach a position in which he would be able to move horizontally over the edges of the cargo hatch of the ship in order, say, to move the drawer from one cargo hold is to another. This guide frame is made with the capability of raising and lowering the inside of the pylon, and a boot tray while lifting the guide frame must be removed and telescopically element - one element to another. Instead telescopic consisting of cylindrical elements drain pipes can be installed funnel elements telescopically positioned by direct or cascading over each other.

Next, the upper sash groove is mostly a funnel-shaped receiving area, the shell, the inner guides and reflecting device, and a hole for side-load floating material, which is transported along the arm, mainly with the help of belt conveyor. This conveyor belt can be on the upper end of the discharging drum, withdrawn or removed from the area of the upper discharge chute. Already mentioned guides and reflecting device are replaceable wearing parts with a straight or curved path.

As the ship loader in the plan alternatives can also be used loader, the upper part of which, together with an arrow horizontally rotated around a vertical axis. At that the head of the arrow describes an arc of a circle, and with a corresponding boom in combination with rogulinym moving ship loader is also possible to reach any point on any cargo hatch of the ship.

Preferably the boom as the boom with articulated shoulders, rotating around a horizontal axis located in the region of the vessel, which is addressed to the ship loader. This form of execution allows a large slope front shoulder arrows, so placed there the tray can go deep in the hold of the vessel, and the height of the drop of the loaded material can be minimized. Unwanted damage to the fractions in the case of a lump of material being transported in the result, among other things, a large drop heights as strong dust generation in the case of powdered bulk materials can thus largely be avoided. To prevent excessive bending of the existing belt conveyor in the transition region between the two articulated between the shoulders of the boom for belt conveyor in the horizontal axis of rotation are provided support by the arc track tape, consisting of several separate segments, moving, rotating and moving relative to each other. Unlike known, for example, from DE 10002018 C2, difficult to manufacture, cumbersome and expensive spring arcs with movable elements, you can create economically and structurally suitable guide DL the conveyor belt, to avoid unacceptably large radii of curvature.

Boot tray, located at the end consisting of articulated shoulders arrows at the bottom of the output end can be provided with stepochkin device for lateral displacement (deviation) of the loaded material in order to achieve a substantially flat surface of the loaded material in the cargo hold of the vessel and thereby the optimal degree of filling of bulk material. In particular, the optimal stowing on Board makes it possible to minimize the danger of displacement of the loaded material under large disturbances of the sea.

In particular, the tray may also be made or maintained in the vertical direction by means of a parallelogram rod.

For supplying feed material to ship loader serve the coastal belt conveyor, persony belt conveyor and trolley with a loop unloading device, with which the bulk material is transferred to the ship loader or installed on it a belt conveyor. Truck with a loop unloading device can be integrated in the ship loader.

Head elements of pile foundations are concrete or steel depending on the design of pile foundations and the need to consider the impact of emerging powers, including prosopo jamnesty.

In General, using the device according to the invention is implemented particularly cost-effective solution for the truck when loading or unloading the vessel. This is in contrast to the prior art for such devices is achieved through:

- lightweight design and economical manufacture of the bridges in place,

- simplicity of construction of the ship loader and a small boom compared to the conventional on the RAID radial trucks with freight trucks,

- waiver of grounds and topsides for - necessary in the case of conventional radial trucks - single berths for vessels and radial crane paths, separate bridge swivel bearings, conveyor distribution stations for dual loaders, access and pedestrian bridges connecting the pier, radial crane path, the distribution station, etc.

In principle, it is known that the cost and powerful device for loading or unloading vessels at anchorage is determined not only one device for loading and unloading vessels, and often to a much greater extent built on the site of buildings. This includes, in particular, elongated berth for vessels with his nitevibe devices and fenders, Foundation, superstructure and crane path for overloading the device, in the case according to the prior art, among other things, known radial loader - base and topside of the rotary support for this overloading of the device, as well as possible with dual constructive execution overhead loaders with swivel bucket base and superstructure for separately located IU the do them distribution station for transferring bulk material arriving from the main supplier to both trucks, and the Foundation and superstructure of the platform for Parking and maintenance, and connection of crane tracks or ways of mileage (ways of maintenance and transportation) between the distribution station, a platform for Parking and maintenance and berths for ships. The purpose of this invention is to create a device for loading the ships in the roads, which could be constructed with minimal technical expenditure and would cost less.

As can be seen from figures 1 to 3, a device for loading vessels at anchorage consists of a steel bridge 1 installed on a concrete heads 3 separate pile foundations 2. This steel bridge 1 can move along the rail of the crane path 4 has a ship loader 5. Ship loader 5 is made with a low portal 6 or 23 (see figure 3 or 9), which is possible because the upper zone of the steel bridge 1 can be mounted relatively high above the water surface 31. This understated design" additional wind loads on the wheels are small. For completeness of the drawings depicts the coastal belt conveyor 32, persony belt conveyor 33 and the carriage 34 with a hinge unloading device, through which the bulk material is fed into the ship loader 5.

The arrow denoted by the and 2 position 35, can be done in different ways, and, however, should always be provided so that the bolt 35 with a certain safety distance to the edge of the hatch - got to any point above the cargo hatch vessel 36 37 or in the hatch 36. Further, from figure 3 can also be understood that between the main bridge beams 7 above the upper belt bridge farm or below established passing the platform 8 for maintenance and transportation.

Ship loader on figure 3, is horizontally rotatable around the vertical axis 5b of the upper structure 5A arrow, made in the form of articulated boom 9, is arranged to swing about a horizontal axis 9a. To the allowable boundary stresses in the tape to withstand the maximum possible value of the radius of curvature, which preterpevaya tape 9b all areas above the axis 9a, arc 10 of the conveyor track is mounted in accordance with figure 4 of the rear stationary segment 11, a front hinged installed segment 12 and the middle segment 13. All the segments 11, 12 and 13 are themselves hard, and is depicted in figure 4, the left end of the segment 12 is mounted on the bolt 9 can be rotated around a horizontal axis 12A, while the other end facing the bolt area of the segment 11 has the AK can be rotated around a horizontal axis 12b, and can travel almost tangent to the reference contour segment 11. Segment 13 of its first end attached to the segment 12 can be rotated around a horizontal axis 13A, and its other end in facing the arrow 9 region as well as with the possibility of rotation around the horizontal axis 13b, and can travel approximately following the contour of the segment 11. Bearing selected in accordance with figure 4, in comparison with the spring elements made in one piece, as it is known, for example, from DE 10002018 A1, has the advantage that it at length, needed for sufficiently large bend radius, easier to manufacture and cheaper.

Figure 5 in the enlarged view shows the guide on the basis of a parallelogram thrust 15, which regardless of the vertical angle (swing angle) of the boom 9 vertically holds the input tray 14. The horizontal axis 9 about which the boom can swing passes between the vertical plane formed by the flange 37A of the vessel and the vertical part of the steel bridge 1, facing the ship. This is the location of the axis of swing allows, in particular, when not loaded or not loaded vessel large tilt shafts 9, which provides a deep dive chute 14 in the cargo t the Hume vessel.

A variant embodiment of the invention depicted in Fig.6-8, is a ship loader 5 with the bolt 16 with the belt conveyor 16A, moving horizontally and transversely of the path of movement of the loader 5 and the longitudinal axis of the vessel. Balancing the center of gravity of the boom 16 is moved horizontally along its longitudinal axis, is achieved by means of the counterweight 17, mounted on the boom 16 can be moved (and, if necessary, and rotation).

A variant of the invention, presented at Fig and 9, depicts two mounted on a common shaft 21 of the gear 19, 20, included in engagement with the racks 24 and 25. The toothed rack 24 fixed to the boom 16, the toothed rack 25 on the counterweight 17. The counterweight 17 rests on the rollers 18. The common shaft 21 (to avoid sticking), mainly located on the swinging lever 22, pivoted on the portal 23. The path of movement of the counterweight 17 relative to the path of movement of the boom 16 is determined by the ratio of the diameters of the two gears 19, 20. Thus the counterweight 17 is moved in the opposite direction relative to the boom 16.

The bolt 16 has on its facing toward the vessel end of the raised or "clean" up the boot tray, consisting of the upper discharge chute 26, telescopic drain pipe 27 (supplied with the Oh stepochkin device 27A), and the guide frame 28 for cleaning the chute. Guide frame 28 moves inside the pylon 29. To boot tray from the position shown in Fig.6, to get in position 7, you must release the way up to the head of the boom 16, which is leaving the drum 30 of the conveyor belt 16A, floating according figa, 6b or 6C with the movable frame 40 back (figa) or turn with the turning frame 41 to the side or upwards, or, alternatively, installed motionless, and the rear lower portion 42 of the tray, whereas the exposed edge of the retractable tray is made separately from the front part 43 in the stationary or, as shown, the folding version.

Instead telescopic drain pipe 27 can be also applied to be suspended by chains or belts funnel 38, shifting into each other (like a funnel in the funnel), or cascading located tray funnel 39.

Figure 11 shows that as the boom 16 and the pylon 29, clerk, together with a lifting device 29A for cleaning chute can be performed, for example, in the form of a continuous structure with lattice crossbars (possible, and in some cases even expedient, and pure lattice structure).

On figa depicted pylon 29 and boot tray 6, the view from the front side (after the and). Here is shown schematically slivochnoe device 27, fixed on the lower part (the ring) telescopic drain pipe 27, in turn, mounted on the guide frame 28; the upper discharge chute 26 and the guide bearing 28a of the guide frame 28 in the pylon 29. Further depicts a lifting device 29A with the lifting cables 29b connected with the guide frame 28.
