Description

Technical Field

[0001] This utility model belongs to the technical field of steel tower transportation fixtures, specifically relating to a deformation-resistant fixture for short-distance transportation and placement of steel towers. Background Technology

[0002] During short-distance transportation, wind turbine steel towers can develop elliptical deformation if effective measures are not taken. This elliptical deformation can cause the tower's flatness and straightness to fail to meet design requirements, thus affecting the overall structural stability and load-bearing capacity. Elliptical deformation can also cause localized stress concentration in the tower, increasing the risk of material fatigue and potentially leading to cracks or even fractures during long-term use. In severe cases, it can affect the assembly and connection of the tower. Furthermore, elliptical deformation can affect the fitting precision of various tower components, leading to assembly difficulties or even preventing proper connection, thus impacting the overall performance and service life of the tower. It can also reduce the tower's stiffness and stability, making it more susceptible to deformation under wind loads, snow loads, and other external forces, affecting its safety and service life.

[0003] In summary, there is a need for a deformation-resistant tooling that can solve the problem of deformation during the transportation of steel towers. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a deformation-resistant fixture for short-distance transportation and placement of steel towers that is easy to install.

[0005] The technical solution of this utility model is as follows:

[0006] A deformation-resistant fixture for short-distance transport and placement of steel towers includes three channel steels arranged in a "three" shape from top to bottom. The three channel steels are all fixed to the steel tower by fastening bolts. Two sets of auxiliary supports are provided on the steel tower, and each set of auxiliary supports forms a placement groove with the steel tower. After the channel steels are placed in the placement groove, the holes on the channel steels are horizontal with the holes on the steel tower.

[0007] Furthermore, the auxiliary supports are auxiliary support one and auxiliary support two with the same structure. Auxiliary support one includes a fixing plate symmetrically fixed to the steel tower and an L-shaped receiving plate fixed to the fixing plate. The vertical surface of the receiving plate is spaced from the circular side surface of the steel tower to form a placement groove.

[0008] Furthermore, the upper end of the receiving plate is bent toward the side opposite to the steel tower to form a guide section.

[0009] Furthermore, the fixing plate has fastening holes, and a tapered rod inserted into the hole of the steel tower tube is fixed on the fixing plate.

[0010] Furthermore, the bottom of the receiving plate is provided with ribs that are fixed to the fixing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses channel steel one, channel steel two, and channel steel three to position the circumferential side of the steel tower to avoid deformation, and uses the placement groove formed between the auxiliary support and the steel tower to position channel steel one and channel steel two, thereby facilitating the installation of channel steel one and channel steel two.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 2 As shown, a deformation-resistant fixture for short-distance transportation and placement of steel towers includes three channel steels arranged in a "three" shape from top to bottom: channel steel 1 2, channel steel 2 3, and channel steel 3 6. Channel steel 1 2, channel steel 2 3, and channel steel 3 6 are all fixed to the steel tower 1 by fastening bolts 5. Two sets of auxiliary supports are provided on the steel tower 1, and each set of auxiliary supports forms a placement groove with the steel tower 1. After channel steel 1 2 and channel steel 2 3 are placed in the placement groove, the holes on channel steel 1 2 and channel steel 2 3 are horizontal with the holes on the steel tower 1.

[0018] During use, since the position of channel steel 36 is relatively low, personnel first install channel steel 36, then install the corresponding auxiliary support after the steel tower 1, and place channel steel 23 and channel steel 12 into the placement slot. At this time, the holes of channel steel 12 and channel steel 23 are horizontal with the holes on the steel tower 1. Then push the corresponding channel steel 12 and channel steel 23 to move so that the holes of channel steel 12 and channel steel 23 are aligned with the holes on the steel tower 1, and then fix them with fastening bolts 5.

[0019] It should be noted that the appropriate channel steel model should be selected based on the diameter and weight of the steel tower 1 to ensure that the channel steel strength meets the requirements. The first section of channel steel should be cut to the length of the steel tower 1 with respect to its diameter. Drill holes at both ends of the first section according to the spacing of the bolt holes on the left and right sides of the flange at the horizontal centerline of the steel tower 1, with dimensions consistent with the bolts used for connection. The second section of channel steel should be cut to a horizontal position 7-10 bolt holes above the bolt holes on the left and right sides of the flange at the horizontal centerline of the steel tower 1, and drill holes at both ends of the second section according to this bolt hole spacing. Similarly, the third section of channel steel should be cut to a horizontal position 7-10 bolt holes below the bolt holes on the left and right sides of the flange at the horizontal centerline of the steel tower 1, and drill holes at both ends of the third section according to this bolt hole spacing.

[0020] In this embodiment, the auxiliary supports are auxiliary support one 4 and auxiliary support two 7 with the same structure. Auxiliary support one 4 includes a fixing plate 41 symmetrically fixed on the steel tower 1 and an L-shaped receiving plate 43 fixed to the fixing plate 41. The vertical surface of the receiving plate 43 is spaced from the circular side surface of the steel tower 1 to form a placement groove.

[0021] In use, an L-shaped receiving plate 43 forms a placement groove between itself and the steel tower 1. After channel steel 1 2 or channel steel 2 3 is placed in the placement groove, the holes of channel steel 1 2 and channel steel 2 3 are aligned with the holes on the steel tower 1, which facilitates the installation and fixing of channel steel 1 2 and channel steel 2 3.

[0022] In this embodiment, the upper end of the receiving plate 43 is bent toward the side opposite to the steel tower 1 to form a guide portion 44.

[0023] During use, the guide section 44 facilitates the placement of channel steel 1 2 and channel steel 2 3 into the placement slot;

[0024] In this embodiment, a fastening hole 45 is provided on the fixing plate 41, and a tapered rod 42 is fixed on the fixing plate 41 and inserted into the hole of the steel tower 1. In use, the tapered rod 42 is inserted into the hole of the steel tower 1, and then the fixing plate 41 is rotated so that the fastening hole 45 is aligned with the hole on the steel tower 1. Then, the bolt is passed through the fastening hole 45 and tightened on the steel tower 1, which facilitates the installation of the fixing plate 41.

[0025] It should be noted that, Figure 2 The tapered rod 42 in the figure is a perspective structure, so it is represented by a dashed line.

[0026] In this embodiment, the bottom of the receiving plate 43 is fixed with a rib plate that is fixed to the fixing plate 41. The rib plate ensures the stability of the connection between the receiving plate 43 and the fixing plate 41.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
