[0037] like Figure 1 As shown, the column head 03 includes a column head plate 031, a lug plate 032 and a pin 2033, and the column head plate 031 and the lug plate 032 are independent parts relative to the column 5. In the prior art, additional parts are provided on the column 5 to achieve the connection between the main cable 104 and the inclined-stayed assembly 902 and the column 5 through the pin 2033.

[0038] See also Figure 2-Figure 5 Some embodiments of the present application disclose a column head 10, which has the function of connecting a column 5, a main cable 1 and a diagonal assembly 9, and enabling the main cable 1 and the diagonal assembly 9 to be adjusted within a certain angle range.

[0039] The column head 10 includes a pin shaft 2, a pin hole 3 and a main cable adjustment hole 4. The pin shaft 2 and the main cable adjustment hole 4 are provided on the column 5. The pin hole 3 is used to install the pin shaft 2. The pin hole 3 is provided through the column 5. The pin shaft 2 is inserted into the pin hole 3 to realize the installation of the pin shaft 2 on the column head 10.

[0040] Both ends of the pin shaft 2 are exposed from the pin hole 3 to form an extension section 21. Figure 3As shown, both ends of the pin 2 protrude from the column head 10, and the portion of the pin 2 protruding from the column head 10 is an extension section 21 of the pin 2 outside the column head 10. The extension section 21 has a locking structure 6, and the locking structure 6 is used to limit the pin 2 along its own axial direction to prevent the pin 2 from escaping from the pin hole 3, so as to form a pin node in which the pin 2 and the column head 10 are integrated.

[0041] The main cable adjustment hole 4 is set through the column head 10, and the pin shaft 2 is provided with a concave platform 22. The center of the concave platform 22 is provided with a main cable fixing hole 23 adapted to the main cable 1. The main cable fixing hole 23 corresponds to and is connected with the main cable adjustment hole 4. After the pin shaft 2 is installed in the pin hole 3, the main cable fixing hole 23 is connected with the main cable adjustment hole 4. The main cable 1 passes through the main cable adjustment hole 4 and the main cable fixing hole 23 and is fixed by the anchoring structure 7. The anchoring structure 7 is in contact with the concave platform 22. The main cable 1 can adjust the pitch angle in the main cable adjustment hole 4.

[0042] In this solution, a pin hole 3 and a main cable adjustment hole 4 are opened on the column 5, and the pin shaft 2 is inserted into the pin hole 3 to form a column head 10 on the column 5. There is no need to add parts to the column 5 to form a structure for installing the pin shaft 2 and the main cable 1. On the one hand, the number of parts is reduced and the cost of the column head 10 is reduced. On the other hand, the process of assembling the column head 10 and the process of assembling the column head 10 on the column 5 are omitted, thereby simplifying the assembly process of the end bracket 11 with the column head 10 and improving the assembly efficiency of the end bracket 11.

[0043] The column head 10 is preferably set at the end of the column 5 that is not connected to the ground foundation. The column head 10 may also not be set at the end of the column 5 that is not connected to the ground foundation, but at a distance from the end, thereby increasing the flexibility of setting the column head 10 on the column 5.

[0044] In this solution, a pin hole 3 and a main cable adjustment hole 4 are opened on the column 5 to form a column head 10 on the column 5. There is no need to connect the column 5 with the column head 10, which not only ensures the connection strength between the column 5 and the column head 10, but also avoids the influence of the unstable connection structure on the connection strength between the column 5 and the column head 10.

[0045] The column head 10 disclosed in the present solution is a structure of the column head 10 after the pin hole 3 and the main cable adjustment hole 4 are opened in the column 5. The structure of the column 5 outside the pin hole 3 and the main cable adjustment hole 4 serves as the structure of the column head 10. Compared with the prior art, the column head plate and the ear plate and other components are omitted, which is a subtractive design, which is contrary to the additive design idea of ​​the column head 10 in the related art. Although the present solution realizes the setting of the column head 10 through subtractive design, it does not affect the connection strength between the column head 10 and the column 5. The connection strength between the column head 10 and the column 5 is not affected by the welding quality, and the connection strength between the column head 10 and the column 5 is improved to a certain extent.

[0046] In some embodiments, the locking structure 6 includes a latch 61 and a socket 62, and the socket 62 is provided on the pin shaft 2. The latch 61 cooperates with the socket 62, so that when the pin shaft 2 is subjected to a force along its own axis, the latch 61 can limit the movement of the pin shaft 2 to prevent the pin shaft 2 from slipping out of the pin hole 3.

[0047] A latch pin 61 and a socket 62 are provided at both ends of the pin shaft 2 in the axial direction to achieve effective position limiting of the pin shaft 2 along its own axial direction.

[0048] The angle between the axis of the insertion hole 62 and the axis of the pin shaft 2 is 80°-95°.

[0049] The present scheme also discloses another embodiment of a locking structure 6, which includes a retaining ring and an annular groove. The annular groove is formed on the pin shaft 2, and the annular groove matches the shape of the retaining ring. The retaining ring is embedded in the annular groove, and the outer wall of the retaining ring protrudes from the outer wall of the pin shaft 2 to form an annular limiting protrusion on the outer wall of the pin shaft 2, so that when the pin shaft 2 is subjected to a force along its own axial direction, the retaining ring can limit the movement of the pin shaft 2 to prevent the pin shaft 2 from slipping out of the pin hole 3.

[0050] The connection between the locking structure 6 and the pin shaft 2 is preferably a detachable connection to facilitate installation and removal of the pin shaft 2 .

[0051] The anchoring structure 7 includes a clip anchor 71 and an extrusion anchor 72, wherein the clip anchor 71 abuts against the surface of the recessed platform 22, and the contact surface of the clip anchor 71 is located inside the recessed platform 22 to increase the contact area between the clip anchor 71 and the surface of the groove, reduce the relative shaking between the clip anchor 71 and the pin shaft 2, and improve the stability of the cooperation between the clip anchor 71 and the pin shaft 2.

[0052] like Figure 4 and Figure 5 As shown, the recessed platform 22 is a groove-shaped structure formed by cutting the outer wall of the pin shaft 2, and the table top of the recessed platform 22 is the groove bottom of the groove-shaped structure, and the groove bottom is a plane; optionally, the groove wall of the groove-shaped structure can fit with the side wall of the clip anchor 71, so as to achieve the limitation of the clip anchor 71 on the basis of increasing the contact area between the clip anchor 71 and the recessed platform 22, thereby further improving the stability of the cooperation between the clip anchor 71 and the pin shaft 2.

[0053] The extrusion anchor 72 is located at the end of the main cable 1 .

[0054] The main cable adjustment hole 4 is formed through the column head 10 , and the main cable adjustment hole 4 has a space for adjusting the pitch angle of the main cable 1 along the length direction of the column 5 .

[0055] The cross section of the main cable adjustment hole 4 along the length direction of the column 5 can be an elongated strip, and the length direction of the elongated hole is parallel to the length direction of the column 5, so that the main cable 1 can move along the opening direction to achieve pitch angle adjustment.

[0056] In the embodiment where the cross section of the main cable adjusting hole 4 along the length direction of the column 5 is in the shape of an elongated strip, the cross section of the main cable adjusting hole 4 may be in the shape of an oblong circle, a rectangle, or other shapes.

[0057] The cross section of the main cable adjustment hole 4 along the length direction of the column 5 is not limited to a long strip hole, and can also be circular, polygonal, or irregularly shaped.

[0058] In some embodiments, the pin hole 3 and the main rope adjustment hole 4 are cut by at least one of laser cutting, thermal cutting, flame cutting, cold cutting and water cutting. The specific cutting method is selected by technical personnel in this field according to actual needs and is not specifically limited here.

[0059] The pin hole 3 and the main cable adjustment hole 4 are manufactured through a cutting process, so that quality control and production efficiency can be improved.

[0060] Since the present solution is to open the pin hole 3 and the main cable adjustment hole 4 on the column 5 to form the column head 10 on the column 5. The opening of the pin hole 3 and the main cable adjustment hole 4 will reduce the strength of the column 5 to a certain extent. During the working process, the position where the pin hole 3 of the column 5 cooperates with the pin shaft 2 is mainly subjected to a large force. The forces of the inclined-stayed assembly 9 and the main cable 1 are applied to the position where the pin hole 3 is opened on the column 5 through the pin shaft 2. In order to ensure the strength of the position where the pin hole 3 is opened on the column head 10, the column head 10 disclosed in the present solution also includes a reinforcing plate 8, which is provided with a plate hole corresponding to the position of the pin hole 3. The pin shaft 2 passes through the pin hole 3 and the plate hole and is fixed by the locking structure 6.

[0061] Specifically, the reinforcing plate 8 is welded to at least one side of the column 5 where the pin hole 3 is opened, so as to strengthen the column 5 after the hole is opened and prevent the column 5 from yielding and deforming due to the force caused by the hole.

[0062] The pin hole 3 is set through the column 5. Preferably, there are at least two reinforcing plates 8, and reinforcing plates 8 are respectively set on both sides of the column 5. The reinforcing plate 8 can be a single-layer plate structure or a multi-layer plate structure, and the number and structure of the reinforcing plates 8 located at both ends of the pin hole 3 can be the same or different.

[0063] In some embodiments, the reinforcing plate 8 is a U-shaped cover plate, and the side plate edges of the U-shaped cover plate are welded to the column 5. The U-shaped cover plate has a bottom plate and two side plates, the two side plates are respectively located at both ends of the axial direction of the pin hole 3, the side plates are provided with plate holes, and the bottom plate abuts against the end surface of the column 5.

[0064] The reinforcing plate 8 adopts a U-shaped cover plate structure. After the U-shaped cover plate is matched with the column 5, both sides of the column 5 can be reinforced at the same time. Compared with the embodiment in which the reinforcing plate 8 is a sheet structure, the assembly process of the end bracket 11 with the column head 10 can be further simplified, and the processing efficiency of the end bracket 11 can be improved.

[0065] In some embodiments, the reinforcing plate 8 is a shell structure adapted to the shape of the column 5, one end of the shell structure is an open end, the end of the shell structure opposite to the open end is a closed end, the closed end abuts against the end surface of the column 5, and the shell structure is provided on the column 5 through the open end cover. In this embodiment, the shell structure has not only a plate hole connected to the pin hole 3, but also a through hole connected to the main cable adjustment hole 4. In this embodiment, the shell structure can enhance the strength of the outer periphery of the column 5, and further reduce the influence of the opening on the strength of the column 5.

[0066] The cross section of the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length of the column 5 is rectangular, and one end of the column 5 provided with the column head 10 has four side surfaces, two of which are arranged oppositely for opening the pin hole 3, and the other two oppositely arranged side surfaces are used for opening the main cable adjustment hole 4. The end of the column 5 provided with the column head 10 is in a cubic shape as a whole, which can reduce the difficulty of opening the pin hole 3 and the main cable adjustment hole 4.

[0067] The cross section of the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length of the column 5 may be the same as or different from the cross section of the second end of the column 5 not provided with the column head 10 along the direction perpendicular to the length of the column 5. Specifically, the cross section of the second end of the column 5 along the direction perpendicular to the length of the column 5 may be rectangular, circular, or other polygonal.

[0068] Optionally, the cross-sectional area of ​​the first end of the column 5 provided with the column head 10 along the direction perpendicular to the length of the column 5 is larger than the cross-sectional area of ​​the second end of the column 5 not provided with the column head 10 along the direction perpendicular to the length of the column 5, so that the circumferential dimension of the first end of the column 5 is larger than the circumferential dimension of the second end of the column 5, thereby making the strength of the first end of the column 5 greater than the strength of the second end of the column 5, thereby reducing the influence of the opening on the strength of the first end of the column 5.

[0069] Preferably, the size of the first end of the column 5 gradually decreases toward the second end of the column 5 , or the first end of the column 5 smoothly transitions to the second end of the column 5 to reduce stress concentration.

[0070] In some embodiments, a step surface may also be formed between the first end of the column 5 and the middle portion of the column 5 .

[0071] Although welding is inevitably used in this solution, the welding position is not the connection position between the column head 10 and the column 5, that is, it is not the main force-bearing position of the column head 10. Therefore, the requirements for welding quality are not high, and the welding quality will not too much affect the connection strength between the column head 10 and the column 5, achieving a balance between manufacturing and performance.

[0072] The present scheme also discloses an end bracket 11, comprising the column head 10 and the diagonal-stayed assembly 9 recorded in any one of the above schemes, one end of the diagonal-stayed assembly 9 is connected to the extension section 21 of the pin shaft 2 of the column head 10, and the other end of the diagonal-stayed assembly 9 is fixed to the ground foundation.

[0073] Since the column head 10 has the above-mentioned technical effects, the end bracket 11 having the column head 10 also has the same technical effects, which will not be described in detail herein.

[0074] like Figure 3 As shown, the connection position of the inclined-stayed component 9 and the extension section 21 of the pin 2 is located between the locking component and the reinforcing plate 8. The locking component can limit the inclined-stayed component 9 and the pin 2 at the same time, not only limiting the pin 2 along its own axial direction, but also limiting the inclined-stayed component 9 along the axial direction of the pin 2, to prevent the inclined-stayed component 9 from shaking during operation and affecting the use effect.

[0075] like Figure 2 As shown, in this solution, the column 5 with the column head 10 is anchored to the ground foundation through the column tensile pile 13, and the inclined-stayed assembly 9 is anchored to the ground foundation through the inclined-stayed assembly tensile pile 14, ensuring the stable connection between the column 5 and the inclined-stayed assembly 9 and the ground foundation. The column 5, the inclined-stayed assembly 9, the column tensile pile 13 and the inclined-stayed assembly tensile pile 14 form a triangular structure to provide stable tensioning force for the main cable 1.

[0076] In some embodiments, a connection structure is provided between the column tensile pile 13 and the inclined tension assembly tensile pile 14 to improve the integrity and stability of the end bracket 11 .

[0077] like Figure 2 As shown, a connecting plate is provided below the column 5, and the connecting plate is fastened to the column tensile pile 13 by bolts. A fixing plate is provided on the side of the connecting plate facing the column 5, and the shape of the fixing plate is adapted to the outer peripheral shape of the column 5, and the fixing plate is fastened to the outer periphery of the column 5 by bolts.

[0078] In some embodiments, the extension section 21 of the pin 2 is connected to the diagonal assembly 9 through a live bolt 12. Specifically, there are two live bolts 12, and they are respectively located at the extension sections 21 at both ends of the pin 2. One end of the live bolt 12 is rotatably connected to the pin 2, and the other ends of the two live bolts are connected to a plate-like connector. The plate-like connector connects the two live bolts 12 together, and the portion of the plate-like connector located between the two live bolts 12 is connected to the diagonal assembly 9 to ensure that the diagonal assembly 9 applies uniform tension to both ends of the pin 2 through the plate-like connector and the live bolt 12, so as to ensure that the two ends of the column 5 located in the axial direction of the pin 2 are uniformly stressed. The live bolt 12 is located between the locking structure 6 and the reinforcing plate 8, and the locking structure 6 also limits the live bolt 12 bolts.
