Technical Field

The invention relates to a transportation tool, in particular to a mixed tower node transportation fixing tool and an installation method thereof.

Background

In the last decade, the blade diameter of domestic mainstream wind turbines is increased from 68 meters to 116 meters by 70%, and the rated power of a single fan is also improved by 50% -100%. The tower barrel is a key part of a wind field foundation and is a tower rod for wind power generation, supports the whole wind power generation machine to work and absorbs the vibration of the machine set. Generally, the higher the altitude, the better the wind resources. At present, land wind power of more than 2MW and offshore wind power of more than 5MW belong to high-end products. In order to match with the high-end products, three or more types of towers are derived from the assembled mixed tower frame according to different heights and split forms.

An assembled tower cylinder of a mixed tower is a support body used for supporting wind power generation equipment, and a wind power tower cylinder can be produced, maintained and processed in a factory workshop through a prefabricated mode, and then finished products can be stored and stacked until the wind field is conveyed to be spliced to complete construction and hoisting.

At present, need transport a large amount of tower barrels with the component transport vechicle earlier when establishing super high wind-powered electricity generation and mixing the tower, because tower barrel volume is great, is tube-shape or sheet structure moreover, consequently overturn very easily, so can only keep flat the tower barrel on the flat board of component transport vechicle, this can occupy great dull and stereotyped area undoubtedly, leads to whole flat board can only place a small amount of tower barrels. And if the prefabricated tower barrel is damaged in the links of storage, transportation, hoisting and the like, repair is difficult, so that the construction period is delayed and economic loss is caused. Therefore, the tower barrels are vertically fixed on the flat plate of the component transport vehicle, and the problem that the number of the tower barrels placed on the flat plate of the component transport vehicle is too small is solved. However, under the common condition, the vertical transportation is fixed, the inner wall of the tower barrel is tightly jacked by the stop block to support and fix the tower barrel, and once strong wind is encountered, the stop block is easy to slide on the inner wall of the tower barrel, so that the tower barrel is toppled.

To sum up, the following problems exist in the conventional tool:

the inner wall of the node ring piece and the stop block are easy to slide;

the transportation and fixing effect of the node ring sheets is poor;

the stop block used by the vertically fixed tool cannot be connected and fixed with the component transport vehicle;

the requirements of urban road bearing capacity, highway turning radius, height limitation and width limitation are required to be met.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

The invention is used for fixing and transporting the tower drum ring piece and meets the problems of road height limitation and the like.

Thus: the invention provides a fixed frock for transporting a mixed tower node.

Referring to fig. 1, the tool for transporting and fixing the mixed tower node comprises a channel steel frame 1, wherein the channel steel frame 1 is provided with an opening structure, preferably, in the embodiment, the channel steel frame 1 is a U-shaped channel steel, and a rubber block 4 is arranged on the U-shaped channel steel, so that the rubber block 4 is stably arranged on the U-shaped channel steel, and the problems of inclination, sliding and the like cannot occur in the transportation process, therefore, the rubber block 4 can be adhered to the U-shaped channel steel through strong glue, of course, in some embodiments, the rubber block 4 can be fixed to the U-shaped channel steel through fixing modes such as screws and the like, and the premise is that holes are formed in corresponding positions of the rubber block 4 and the U-shaped channel steel, and the screws/screws are conveniently fixed.

Further, in some embodiments, the opening structure of the channel steel frame 1 may also be a V-shaped opening structure, and a rubber block is fixedly disposed on the inner wall of the V-shaped channel steel in the same manner.

Furthermore, since the channel frame 1 is a U-shaped channel in this embodiment, as shown in the figure, the rubber block 4 is a triangular rubber block and is fixed to the channel frame 1.

When the opening structure of the channel frame 1 is a V-shape, it is suggested that the rubber block 4 should be a V-shape and fixed to both walls of the V-shape opening.

In order to realize the binding, fixing and transportation of the node ring sheets.

In this embodiment, the base 2 is assembled at the bottom of the channel frame 1, and the base 2 and the channel frame 1 are fixed by screws or welded. Base 2 horizontal channel-section steel both sides are bent and are constituted, so, base 2's both sides are equipped with the portion of bending 21, form the cell body structure between two portions of bending 21, because two solitary portions of bending 21 stability is relatively poor, take place the possibility of warping easily under the heavy pressurized situation, consequently, as shown in figure 2, set up strengthening rib 23 between two portions of bending 21 for the bearing strength of base 2 portion of bending 21 is strengthened to whole.

In order to prevent the above-mentioned reinforcing ribs 23 from affecting the thread (binding) effect of the channel structure, in this embodiment, the reinforcing ribs 23 are made of steel plates with thread holes, that is, holes are formed in the reinforcing ribs 23.

Further, for the structure between channel-section steel frame 1 and base 2 is more stable, as shown in fig. 1, set up supplementary steel sheet 3 between the both sides of channel-section steel frame 1 and base 2, in this embodiment, this supplementary steel sheet 3 includes first steel sheet 31, second steel sheet 32, third steel sheet 33, and second steel sheet 32 both sides are located perpendicularly to first steel sheet 31 and third steel sheet 33. The second steel plate 32 has another function of assisting binding, and thus, a hole C320 is formed in the second steel plate 32.

In order to bind and fix the node ring pieces, the invention is provided with a hole A11 on the channel steel frame 1 and a hole B22 on the base 2 as shown in figure 1. For convenience of binding and stability considerations, hole a11, hole B22, and hole C320 should be in the same vertical plane.

The invention also provides an installation method of the mixed tower node transportation fixing tool, which comprises the following steps:

step S1, providing a mixed tower node ring sheet with an exposed bolt and a reserved prestressed hole at the top;

step S2, placing the bottom of the mixed tower node ring piece in an opening structure of the channel steel frame;

and S3, placing the base on a flat plate of the transport semi-trailer flat car, using a steel wire rope by utilizing an exposed bolt and a reserved prestressed hole at the top of a mixed tower node ring piece, sequentially passing through a hole A, a hole C and a hole B, and binding the steel wire rope by matching with the flat plate.

Therefore, in step S1, an exposed nut should be fixed on the node ring piece to facilitate the passing of a binding tool such as a wire rope. Or a prestressed hole can be reserved on the node ring sheet, and the function of the prestressed hole is the same as that of the exposed nut.

In step S2, the triangular rubber blocks 4 are provided in the opening structure of the channel steel frame 1, so that the method is adaptable to node ring pieces of different sizes, that is, the positions of the hypotenuse of the triangle of a node ring piece with a small size and a node ring piece with a large size are different, and the node ring pieces are bound stably by matching with the steel wire rope.

It should be noted that, because the prestressed holes/exposed nuts are reserved at the top of the node ring pieces, the problem that the overall height of the ring pieces is higher due to the arrangement of the binding pieces at the top of the node ring pieces is greatly reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
