The invention relates to a method and apparatus for transport of long bulky cargo, first of all blades of wind power plants with a lifting body on the guide ropes.
There is a method of transport of long bulky cargo with the help of tractors. Such transportation takes time and is expensive, especially in case of land transportation is very long, and the infrastructure is not suitable for transportation.
It is known the use of vehicles "lighter than air" for various applications, including in the civilian and military sectors.
Thus, it was proposed to carry large and heavy loads with airship or traction balloons, while when using the airship cargo was placed on the lower platform, and the use of traction balls, as in 75 CL, - in the cargo frame.
From DE 10210540 A1 is known a lifting body on the guide cables primarily for the transportation of cargo that is bound for at least three fixed on the ground, the free length of which can vary due to their ground winches with remote control. The rigging of the balloon consists of a node of the ball, which by means of an intermediate rope tied to the node of the crane, from which radiate tie the rope and the rope with the hook of the crane.
For transportation of heavy loads in areas with poorly developed infrastructure and soils with low capacity DE 10226868 A1 describes a cargo carrier with a tracked vehicle, which is connected with the vehicle "lighter than air", a lifting force which at least partially corresponds to the weight of the load. When loading and unloading lifting force of the balloon more weight and less weight of the vehicle with the cargo. The cargo carrier includes crane winch, the winch cable connected to the cargo hub, and two intermediate cable connected each with one variable geometry mechanism.
The basis of the invention is to provide a method and device for the transport of long bulky goods over long distances, including missing or unsuitable for conventional methods of transportation infrastructure.
The invention solves this task by signs of paragraphs 1 and 2 of the formula. Preferred refinements of the invention are described in dependent claims.
According to the invention the lifting body is equipped suspended underneath the device or the frame in which the transported cargo is stretched at the center of gravity. A lifting body is bound and sent driven winches that are mounted, at least one mobile the Noah unit, for example on a truck. Depending on conditions 2-3 truck with actively managed winches provide much flexibility as possible, to avoid obstacles.
The height and direction of flight of the lifting body along with goods is determined by the movement of the mobile units and the change in the length of the tie ropes. The lifting body can be whatever you like, horizontally and vertically, and the transported cargo can avoid obstacles and yet remain horizontal and constantly rotate in the wind, so as to provide minimum resistance. The transport system consists of several components. Actually spherical lifting body is a balloon or a balloon, made of a special membrane, which serves for receiving carrier gas (hydrogen or helium). Bearing strength is determined by the volume of the ball and used the carrier gas. The increase in bearing strength is possible in principle through the use of a larger ball. The optimal size of the lifting body is determined mainly transported cargo. Actually lifting body obhvatyvala network or other suitable fastening, which in the lower part of the site fixed ball suspension cable. The network is equipped with additional devices on which to logoutresponse cables for attachment of the lifting body, so, for example, if the storm to fix it on earth.
At the end of the suspension cable is lifting device that is specially made for the transported goods. Suspension cable and a lifting device connected with the rotary hinge to the transported cargo could be aligned to the wind and held horizontal by tilting hinge on the lifting device, due to this leeward area is reduced, which ensures safe transportation. Lifting device is specifically provided in correspondence to the shape of the transported goods. To prevent slippage of the load, it is fixed on the lifting device. To do this, depending on the cargo, use various methods, such as escalivada cables or fixing bolts. Soft upholstery, made specifically for the transported goods, prevents damage. On the lower part of the lifting device is fixed connecting cables with mobile hoists. Depending on the scope and type of application may require from one to three mobile winch holders. If you have more than one mobile winch holder, the connection of the traction ropes with lifting device is performed by rotating located double or triple the yarn (the device against twisting), to prevent the formation of knots on the traction ropes. Traction cables are standard crane winches that are mounted on mobile carrier unit. As a mobile transport units principled various transport vehicles, especially trucks. But it is also possible and rail transport units.
The proposed method allows you to transport long objects bulky goods over long distances, in transportation also includes receiving and lowering of the load. The reason for developing the system is to carry blades for wind power plants in mountain regions where conventional transportation by means of truck tractors only possible with very high costs because of the winding roads. But the transport system is also suitable for various other transportable goods, such as long pipes with large diameters. The use makes sense, first of all, if there is no infrastructure or she is not suitable for standard methods of transportation, as well as for soils with low capacity.
Hereinafter the invention is explained in the detailed description of examples of implementation with reference to the drawings.

Figure 4 shows a lifting device 12 with a fixed strap as binding blade 14 15 tense swivel connection with the lifting body 1 and the traction cables 18. Lifting device 12 has, for this purpose, as shown in detail in Fig.6, the device 8 protection against twisting for the lower suspension cable 7 and the traction ropes. On node 5 crane, in addition to the lower suspension cable 7 are even and crane cables 6 to work as a crane.
Figure 5 and 6, the blades 15 shows the open and closed lifting device with a lifting crate when using passenger lifts 11. Lifting device 12 is a stable structure in a suitable design, for example in the form of a frame of two parts, which at one end are rotatable and can be opened hydraulically 10, and after laying of the transported goods 15 is securely closed. Two opposite inner sides have scoreupdate soft upholstery 16 in the form of a half-section of the transported cargo 15, in the embodiment, the blades 15. If transported long tube, soft shell 16 have a cross section in the shape of a semicircle. Lifting device 12 can be performed so that part of it, standing upright when opened, is a passenger lift 11 winch 17 for lifting the crate. Figure 6 on the upper and lower sides of the hanging handling devices 12 are, respectively, the device 8 protection against twisting, and immediately above the point of rotation on opposite sides of the tipping hinges 9.
7 shows the invention to be used as a crane with a balloon when mounting the blades on the generator with manual fixation from wind effects. To do this, three crane cable 6 from node 5 of the valve are connected with the winch 13 on the mobile transport units, due to a corresponding change in length of the individual winches 13 airbag is th ball 1 takes the desired position. Manual fixation from the effects of wind by using a small winch by means of two cables placed on the end of the blade.
The transport is carried out as follows. Transported cargo is placed in position on the place of installation and fix. Lifting the body together with the lifting device is placed in position over the transported cargo. Mobile winch holders set around the transported goods. Transported cargo pull in a load-handling device and fix as necessary. The rise of the transported goods perform by means of the lifting body and the unwinding cable guides with winches or change the location of the mobile winch holders. Navigation of the lifting body along with the transported cargo is due to the biased movement of vehicles and changes the length of the guide ropes. The lowering is carried out in reverse order or simultaneously in mounting position (for example, for the generator on a wind farm), the load due to the connection cables, placed on the top nodes of the faucet, disconnect from the movement of the balloon with the help of located on earth winches, and positioned accurately relative to the threaded connection.
