Exemplary embodiments will be described in detail here, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0026] The following will refer to the appendices in the embodiments of this application. Figure 1-4 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0027] A temporary loading point assembly for a steel pipe tower includes a left arc plate 1, a right arc plate 2, and a middle arc plate 3. The left arc plate 1, right arc plate 2, and middle arc plate 3 together form a hollow cylindrical structure, which better suits the structural characteristics of the steel pipe tower 22 and has a higher fit, so as to clamp the cylindrical steel pipe tower 22 and make the test results more accurate.

[0028] The left arc-shaped plate 1 extends outward from both sides to form a first clamping plate 4 and a second clamping plate 5, the right arc-shaped plate 2 extends outward from both sides to form a third clamping plate 6 and a fourth clamping plate 7, and the middle arc-shaped plate 3 extends outward from both sides to form a fifth clamping plate 8 and a sixth clamping plate 9. Each of the first clamping plate 4, second clamping plate 5, third clamping plate 6, fourth clamping plate 7, fifth clamping plate 8, and sixth clamping plate 9 has a connecting hole. After the bolt 10 passes through the connecting hole, the first clamping plate 4 connects to the fifth clamping plate 8, and the third clamping plate 6 connects to the sixth clamping plate 9. Plate 9, second clamping plate 5, and fourth clamping plate 7 are connected respectively; wherein, the first clamping plate 4 and fifth clamping plate 8, and the third clamping plate 6 and sixth clamping plate 9 extend outward to form a loading plate 11, and corresponding holes are opened on the loading plate 11 to form loading holes 12. At least one loading hole 12 is provided in the height direction of the loading plate 11, so as to apply force to both sides simultaneously using the loading hole 12, so as to achieve a wider variety of external forces in terms of size and combination, improve the accuracy of the applied external forces, and improve the reliability of the test results. In this embodiment, the loading is performed through the loading holes 12 on the corresponding loading plates 11 on the middle arc plate 3, left arc plate 1, and right arc plate 2, avoiding stress concentration caused by directly loading the test piece; the middle arc plate 3, left arc plate 1, and right arc plate 2 are reinforced with a middle stiffening plate 17, a first left stiffening plate 13 and a second left stiffening plate 14, a first right stiffening plate 15 and a second right stiffening plate 16, which ensure the durability of the device by welding the middle stiffening plate 17, the first left stiffening plate 13 and the second left stiffening plate 14, the first right stiffening plate 15 and the second right stiffening plate 16 on the top and bottom.

[0029] In some embodiments, the structures of the left arc-shaped plate 1 and the right arc-shaped plate 2 are symmetrical.

[0030] In some embodiments, the left arc plate 1 is provided with a first left stiffening plate 13 and a second left stiffening plate 14, and the right arc plate 2 is provided with a first right stiffening plate 15 and a second right stiffening plate 16.

[0031] The first left stiffening plate 13 is connected to the first clamping plate 4 at one end and to the left arc plate 1 at the other end; the second left stiffening plate 14 is connected to the left arc plate 1 at one end and to the second clamping plate 5 at the other end; the first right stiffening plate 15 is connected to the third clamping plate 6 at one end and to the right arc plate 2 at the other end; the second right stiffening plate 16 is connected to the right arc plate 2 at one end and to the fourth clamping plate 7 at the other end.

[0032] In some embodiments, at least two of the first left stiffening plate 13 and the second left stiffening plate 14 are provided along the height direction of the left arc-shaped plate 1, and at least two of the first right stiffening plate 15 and the second right stiffening plate 16 are provided along the height direction of the right arc-shaped plate 2. The two first left stiffening plates 13 and the second left stiffening plate 14, or the two first right stiffening plates 15 and the second right stiffening plates 16, are spaced apart to increase the connection strength between the corresponding clamps on both sides of the left arc-shaped plate 1 and the corresponding arc-shaped plate, thereby enhancing the overall structural stability of the loading point assembly.

[0033] In some embodiments, a central stiffener plate 17 is provided on the arc-shaped plate 3. One end of the central stiffener plate 17 is connected to the fifth clamping plate 8, and the other end is connected to the sixth clamping plate 9. Since the presence of the loading plate 11 increases the length of the clamping plates on both sides, and the force is directly applied to the loading plate 11, directly connecting the two sides of the central stiffener plate 17 to the clamping plates can better distribute the force on the two loading plates 11 and improve the accuracy of the test results.

[0034] In some embodiments, at least two central stiffening plates 17 are provided along the height direction of the central arc-shaped plate 3. For example, two central stiffening plates 17 are respectively provided vertically along the height direction of the central arc-shaped plate 3, thereby better enhancing the connection stability between the side plates and the arc-shaped plate.

[0035] In some embodiments, the inner walls of the left arc-shaped plate 1, the right arc-shaped plate 2, and the middle arc-shaped plate 3 are respectively fixedly connected with a left inner liner 18, a right inner liner 19, and a middle inner liner 20. The middle inner liner 20, the left inner liner 18, and the right inner liner 19 have different thicknesses to accommodate different specifications of tower body main material reinforcement devices. The arrangement of the left inner liner 18, the right inner liner 19, and the middle inner liner 20 enhances the structural stability of the corresponding arc-shaped plates while improving the stability and reliability of the results during loading experiments.

[0036] In some embodiments, the lengths of the left inner liner 18, right inner liner 19, and middle inner liner 20 in the horizontal direction are less than the lengths of the left arc plate 1, right arc plate 2, and middle arc plate 3 in the horizontal direction, leaving a certain amount of space to accommodate steel pipe towers 22 of different sizes and improve the universality of the loading point assembly.

[0037] In some embodiments, rubber pads 21 are also provided on the inner walls of the left inner liner 18, right inner liner 19, and middle inner liner 20. The rubber pads 21 are detachably connected to the left inner liner 18, right inner liner 19, and middle inner liner 20, respectively. The rubber pads 21 are made of silicone, rubber, or other materials with a certain degree of elasticity and hardness to ensure the stability of the connection with the steel pipe tower 22, provide sufficient friction while protecting the angle steel of the tested tower, reduce the accident rate of the test, and also reduce hard friction damage to the tower body when clamping the steel pipe tower 22.

[0038] In some embodiments, the loading hole 12 is provided in the height direction of the loading plate 11.

[0039] Using the component structure of this application, first determine the location of the tower body to be loaded and the specifications of the tower body steel pipe, and select a suitable inner lining to place on the outside of the main steel pipe of the tower body to be installed; install the middle arc plate 3, left arc plate 1, and right arc plate 2 on the north side of the steel pipe of the tower body under test, insert bolts 10, and tighten them after determining the position to complete the installation; during the loading test, the steel wire rope can be connected through the loading holes 12 reserved on the middle arc plate 3, left arc plate 1, and right arc plate 2 to complete the loading test; after the test is completed, remove the steel wire rope, loosen and remove the bolts 10 used for fixing, complete the dismantling of the component and recycle and store it.
