Description

Technical Field

[0001] The present invention relates to a transportation tooling, and particularly to a transportation fixing tooling for a hybrid tower node and an installation method thereof. Background Art

[0002] In the past decade, the blade diameter of the mainstream domestic wind turbine models has been extended from 68 meters to 116 meters, an increase of 70%, and the rated power of a single wind turbine has also been increased by 50%-100%. The tower barrel is a fundamental and crucial component for the wind farm, serving as the tower pole for wind power generation, supporting the operation of the entire wind power unit and absorbing the vibration of the unit. Generally, the higher the height, the better the wind resources. Currently, onshore wind turbines above 2 MW and offshore wind turbines above 5 MW belong to high-end products. To match these high-end products, prefabricated hybrid tower racks have also derived three or more categories of tower barrels according to different heights and splitting forms.

[0003] The prefabricated hybrid tower barrel is a framework for supporting wind power generation equipment. Usually, the wind turbine tower barrel will be produced, maintained, and processed in the factory workshop through prefabrication, and then the finished product will be stored and stacked until it is transported to the wind farm for splicing and construction hoisting.

[0004] Currently, when constructing ultra-high wind power hybrid towers, a large number of tower barrels need to be transported by component transport vehicles. Since the tower barrels are large in volume and have a cylindrical or sheet-like structure, they are very easy to tip over. Therefore, the tower barrels can only be placed flat on the flatbed of the component transport vehicle, which will undoubtedly occupy a large flatbed area, resulting in only a small number of tower barrels being placed on the entire flatbed. Moreover, if the prefabricated tower barrels are damaged during storage, transportation, hoisting and other links, it will be very difficult to repair, delaying the construction period and causing economic losses. Therefore, fixing the tower barrel vertically on the flatbed of the component transport vehicle solves the problem of too few tower barrels placed on the flatbed of the component transport vehicle. However, usually, for vertical transportation and fixing, the stop block is used to tightly press against the inner wall of the tower barrel to support and fix the tower barrel. Once encountering strong winds, the stop block is extremely likely to slide on the inner wall of the tower barrel, resulting in the tower barrel tipping over.

[0005] In summary, the traditional tooling has the following problems:

[0006] The inner wall of the node ring plate and the stop block are prone to sliding;

[0007] The transportation and fixing effect of the node ring plate is poor;

[0008] The stop block used in the vertically fixed tooling cannot be connected and fixed to the component transport vehicle;

[0009] It is necessary to meet the requirements of urban road bearing capacity, highway turning radius, height limit, and width limit. Summary of the Invention

[0011] To solve the technical problems existing in the background art, the present invention proposes a transportation and fixing tooling for the hybrid tower node.

[0012] (II) Technical solution

[0013] To solve the above problems, the first aspect of the present invention provides a transportation and fixing tooling for the hybrid tower node, including a channel steel frame, a base, and an auxiliary steel plate. The channel steel frame has an open structure;

[0014] The base is assembled at the bottom of the channel steel frame;

[0036] To make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present invention.

[0037] Since the present invention is used for fixing and transporting the tower barrel ring plate and satisfies problems such as road height limits.

[0038] Therefore: A transportation and fixation tooling for hybrid tower nodes proposed by the present invention.

[0039] Reference Figure 1 , a transportation and fixation tooling for hybrid tower nodes according to the present invention includes a channel steel frame 1, the channel steel frame 1 is provided with an opening structure, preferably, in this embodiment, the channel steel frame 1 adopts a U-shaped channel steel, and a rubber block 4 is arranged on the U-shaped channel steel. In order to make the rubber block 4 stably placed on the U-shaped channel steel and not tilt or slide during transportation, 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 also be fixed to the U-shaped channel steel by fixing methods such as screws, provided that holes are drilled at the corresponding positions of the rubber block 4 and the U-shaped channel steel to facilitate the fixing of the screws / screws.

[0040] Furthermore, in some embodiments, the opening structure of the channel steel frame 1 can also be V-shaped, and the rubber block is fixedly arranged on the inner wall of the V-shaped channel steel in the same manner.

[0041] Furthermore, in this embodiment, since the channel steel frame 1 uses U-shaped channel steel, as shown in the figure, the rubber block 4 is a triangular rubber block and is fixed to the channel steel frame 1.

[0042] It should be noted that when the opening structure of the channel steel frame 1 is V-shaped, it can be inspired that at this time, the rubber block 4 should be V-shaped and fixed to the two walls of the V-shaped opening.

[0043] In order to achieve the bundling and fixing as well as transportation of the node ring plate.

[0044] In this embodiment, a base 2 is assembled at the bottom of the channel steel frame 1, and the base 2 is fixed to the channel steel frame 1 by screws or welding. The base 2 is formed by bending the two sides of the horizontal channel steel. Therefore, the two sides of the base 2 are provided with bending parts 21, and a groove structure is formed between the two bending parts 21. Since the stability of the two separate bending parts 21 is relatively poor and it is easy to deform under the condition of being weighted and pressurized, therefore, as Figure 2 shown, a reinforcing rib 23 is arranged between the two bending parts 21 to integrally enhance the bearing strength of the bending part 21 of the base 2.

[0045] In order to ensure that the above-mentioned reinforcing rib 23 does not affect the effect of wire passing (bundling) of the groove structure, therefore, in this embodiment, the reinforcing rib 23 is made of a steel plate provided with a wire passing hole, that is, a hole is opened on the reinforcing rib 23.

[0046] Further, in order to make the structure between the channel steel frame 1 and the base 2 more stable, as Figure 1 shown, auxiliary steel plates 3 are arranged between the two sides of the channel steel frame 1 and the base 2. In this embodiment, the auxiliary steel plate 3 includes a first steel plate 31, a second steel plate 32, and a third steel plate 33. The first steel plate 31 and the third steel plate 33 are vertically arranged on both sides of the second steel plate 32. Another function of the second steel plate 32 is to assist in bundling. Therefore, a hole is opened on the second steel plate 32, designated as hole C320.

[0047] In order to achieve the bundling and fixing of the node ring plate in the present invention, therefore, as Figure 1 shown, a hole A11 is opened on the channel steel frame 1, and a hole B22 is opened on the base 2. For the convenience of bundling and considering stability, therefore, the hole A11, the hole B22, and the hole C320 should be in the same vertical plane.

[0048] The present invention also provides an installation method for a mixing tower node transportation and fixing tooling, including the following steps:

[0049] Step S1, providing a mixing tower node ring plate with exposed bolts and reserved prestressed holes at the top;

[0050] Step S2: Place the bottom of the mixing tower node ring plate within the opening structure of the channel steel frame;

[0051] Step S3: Place the base on the flatbed of the transport semi-trailer flatbed truck. Use steel wire ropes at the top of the mixing tower node ring plate with exposed bolts and reserved prestressed holes, and sequentially pass through hole A, hole C, and hole B, and cooperate with the flatbed for bundling.

[0052] Therefore, in Step S1, exposed nuts should be fixedly provided on the node ring plate to facilitate the passing of bundling tools such as steel wire ropes. It is also possible to reserve prestressed holes on the node ring plate, and its function is the same as that of the exposed nuts.

[0053] In Step S2, since triangular rubber blocks 4 are provided within the opening structure of the channel steel frame 1, thus, it can adapt to node ring plates of different sizes, that is, the positions of the node ring plates with small size specifications and large size specifications on the hypotenuse of the triangle are different, and cooperate with the steel wire ropes for stable bundling.

[0054] It should be noted that due to the method of reserving prestressed holes / exposed nuts at the top of the node ring plate, the problem of the overall height of the ring plate being too high caused by setting bundling parts at the top of the node ring plate is greatly reduced.

[0055] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
