Description

Technical Field

[0001] This utility model belongs to the field of truss tower technology, and specifically relates to a truss tower with high load strength. Background Technology

[0002] In power systems, truss towers serve as the core supporting facilities for high-voltage transmission lines, playing a crucial role in transmitting electrical energy. With rapid socio-economic development and continuously rising electricity demand, transmission lines are constantly evolving towards higher voltage and larger capacity, placing increasingly stringent requirements on the performance of truss towers.

[0003] From a load-bearing perspective, truss towers must withstand the combined effects of various complex loads over long periods, including the weight of the conductors themselves, additional loads during icing, wind loads at different wind speeds, and impact loads from geological disasters such as earthquakes. Traditional truss towers have certain design shortcomings: First, the density of members in some areas is insufficient, resulting in poor load uniformity and stress concentration in localized areas, which greatly weakens the overall load-bearing capacity of the tower and shortens its service life. Second, they often use single diagonal or transverse members for connection. This simple connection method is difficult to efficiently distribute and transfer loads. When faced with extreme conditions such as strong winds or severe icing, the tower is prone to deformation and may collapse, seriously threatening the safety and stability of power transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a truss iron tower with high load-bearing capacity and strong stability.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a truss iron tower with high load-bearing capacity, comprising four rectangularly arranged tower corner main beams, with tower corner crossbeams fixedly connected to the top of each tower corner main beam, a first reinforcing support mechanism provided between the tower corner main beams and the tower corner crossbeams, an inner curved arm main beam fixedly connected to the top of each tower corner main beam, a tower head base assembled between the four inner curved arm main beams, with crossbeam main beams fixedly connected to both ends of each tower head base, and outer crossbeams symmetrically assembled between the crossbeam main beams and the inner curved arm main beams. The main beam has a cantilever beam, with a second reinforcing support mechanism between the two outer cantilever beams and a third reinforcing support mechanism between the two inner cantilever beams. The top of the crossarm main beam has a symmetrically arranged tower head sub-beam fixedly connected to the tower head base. The surfaces of the tower head base and the tower head sub-beam are respectively fixedly connected to three hanging points. One end of the tower head sub-beam and one end of the crossarm main beam are equipped with a crossarm connecting beam. A connecting mechanism is provided between the two crossarm connecting beams. A fourth reinforcing support mechanism is assembled between the inner and outer cantilever beams.

[0006] The above technical solution utilizes a multi-layered reinforcement structure, including a first reinforcing support mechanism between the tower corner main beam and the tower corner crossbeam, a fourth reinforcing support mechanism between the inner curved arm main beam and the outer curved arm main beam, a second reinforcing support mechanism between the two outer curved arm main beams, a third reinforcing support mechanism between the two inner curved arm main beams, and a connection mechanism between the two crossarm connecting beams. This structure effectively disperses and transfers loads from multiple key parts such as the tower corner, curved arm, and crossarm, avoiding local stress concentration and greatly improving the overall load-bearing capacity of the tower. It can better cope with complex loads such as conductor self-weight, icing, and strong winds. Furthermore, each reinforcement support mechanism employs a stable structural form such as cross members, for example, the second reinforcing support mechanism... The cross-arrangement of the first and second connecting rods in the support mechanism, and the cross-arrangement of the first and second diagonal braces in the connection mechanism, forms a stable truss structure system. This structural system enables the tower to maintain good structural stability when bearing loads, making it less prone to deformation or collapse. This effectively ensures the safety and stability of power transmission, significantly enhancing structural stability. Through the structural design of components such as the tower corner main beam, combined with the role of various reinforced support mechanisms in improving overall structural stability, the tower can adapt well to different terrain environments. It can also play a stable role in the construction of power transmission lines in complex terrains such as mountains and hills, expanding the application scenarios of the tower and improving its terrain adaptability.

[0007] The present invention is further configured such that the first reinforcing support mechanism includes a tower corner inclined beam fixedly connected between the tower corner main beam and the tower corner cross beam, and a horizontal support rod and an inclined support rod are assembled between the tower corner inclined beam and the tower corner main beam, and the number of the horizontal support rod and the inclined support rod is multiple.

[0008] The above technical solution involves directly transferring the load borne by the tower corner beam to the tower corner main beam via the tower corner inclined beam, forming the main force path. Multiple horizontal and inclined support rods further disperse the load, transferring the local stress between the tower corner inclined beam and the tower corner main beam to the surrounding members, avoiding stress concentration in a single location. The overall structure enhances the rigidity of the tower corner area through multi-node connections, reduces deformation at the connection between the tower corner main beam and the tower corner beam, and improves the overturning resistance of the tower base. This structure achieves the characteristics of "clear force distribution and simple connection," simplifying assembly while strengthening the overall load-bearing capacity of the tower corner area through the collaborative bearing of multiple members.

[0009] The present invention is further configured such that a first support rod is assembled between the tower corner beam and the inner curved arm main beam, and a second support rod is assembled between the first support rod and the tower corner main beam.

[0010] The above technical solution involves the following: the first support rod is mounted at both ends to the tower corner crossbeam and the inner curved arm main beam, forming an oblique connection between them. The second support rod is mounted at both ends to the middle of the first support rod and the tower corner main beam, creating a triangular stable structure. The first support rod, as the main force transmission component, transfers the upper load borne by the inner curved arm main beam to the tower corner crossbeam, forming a longitudinal force transmission path from the inner curved arm to the tower corner. The second support rod, by forming a triangular structure with the first support rod and the tower corner main beam, enhances the stability of the first support rod, preventing it from bending or swaying under load. Together, they disperse the load of the upper structure to the tower corner main beam, reducing stress concentration at the connection between the tower corner crossbeam and the inner curved arm main beam, and improving the overall load-bearing capacity of the upper and lower connection areas of the tower.

[0011] The present invention is further configured such that the second reinforcing support mechanism includes a plurality of first connecting rods and second connecting rods symmetrically assembled between the two outer curved arm main beams, wherein the first connecting rods and the second connecting rods are arranged in a cross configuration.

[0012] The above technical solution employs a symmetrical distribution of multiple first and second connecting rods, each end of which is assembled between two opposing outer curved arm main beams. The first and second connecting rods intersect to form an "X" shape. The intersection points are typically fixed by bolts or welding, forming multiple sets of cross support units. The intersecting first and second connecting rods rigidly connect the two outer curved arm main beams into a whole, creating a frame structure with stronger lateral stiffness in the outer curved arm area. This effectively resists lateral forces generated by horizontal wind loads or conductor tension. The symmetrically distributed sets of cross units can evenly transfer the load borne by the outer curved arm main beam to both sides, avoiding deformation caused by excessive force on one side. The "X" shaped cross structure disperses the load through axial force distribution of the rods, reducing the bending stress of the outer curved arm main beam and improving the overall deformation resistance and load-bearing capacity of the curved arm area.

[0013] The present invention is further configured such that the third reinforcing support mechanism includes a plurality of first reinforcing rods and second reinforcing rods symmetrically assembled between the two inner curved arm main beams, the first reinforcing rods and second reinforcing rods being arranged in a cross configuration, and a third reinforcing rod being assembled between the first reinforcing rods and second reinforcing rods and the inner curved arm main beams.

[0014] The above technical solution employs a symmetrical distribution of multiple first and second reinforcing rods, each end of which is assembled between two opposing inner curved arm main beams, forming an "X" shape through their intersection. The intersection points are typically connected by bolts. One end of a third reinforcing rod is connected to the intersection of the first and second reinforcing rods, while the other end is assembled to the inner curved arm main beam. This allows the third reinforcing rod, the inner curved arm main beam, and the intersecting first and second reinforcing rods to collectively form multiple triangular stabilizing units. The intersecting first and second reinforcing rods connect the two inner curved arm main beams as a whole, enabling bidirectional transmission of horizontal loads and preventing lateral displacement or torsion of the inner curved arm main beams due to unilateral stress. The third reinforcing rod, through its triangular structure, strengthens the stability of the intersection nodes, directly transferring the loads borne by the first and second reinforcing rods to the inner curved arm main beam, shortening the force transmission path, and reducing stress concentration at the intersection points.

[0015] The present invention is further configured such that the connecting mechanism includes a plurality of first and second diagonal braces symmetrically assembled between the two crossbeams, wherein the first and second diagonal braces are arranged in a cross configuration.

[0016] The above technical solution employs a symmetrical arrangement of multiple first and second diagonal braces, each fixedly assembled at both ends to two oppositely positioned crossarm connecting beams. The first and second diagonal braces intersect to form an "X" shape, with the intersection points secured by connectors such as bolts. The entire structure is located in the space between the two crossarm connecting beams, forming a closed load-bearing frame together with the crossarm connecting beams. The intersecting first and second diagonal braces rigidly connect the two crossarm connecting beams, forming a laterally stable structure that effectively resists horizontal thrust generated by conductor tension, wind loads, etc., preventing lateral deformation or misalignment of the crossarm connecting beams. The symmetrically distributed multiple sets of "X"-shaped structures can evenly distribute the load, allowing the force borne by the crossarm connecting beams to be transmitted bidirectionally along the diagonal braces, avoiding localized stress concentration.

[0017] The present invention is further configured such that the interior of the main crossbeam is equipped with a plurality of cross-arranged tension bars, and the tower head sub-beam and the main crossbeam are equipped with a plurality of connecting railings.

[0018] The above technical solution employs the following: tension rods are arranged crosswise inside the main crossbeam, with both ends fixedly connected to the inner sidewall of the main crossbeam, forming an "X"-shaped or grid-like internal support structure. Connecting railings are mounted on the sides of the tower head sub-beam and the top of the main crossbeam, evenly distributed along their connecting edges, forming a triangular auxiliary support together with the tower head sub-beam and the main crossbeam. The tension rods enhance the rigidity of the main crossbeam itself. The crosswise arrangement of the tension rods effectively resists the tensile deformation and bending stress generated by the main crossbeam under conductor loads. By dispersing the load through axial force distribution of the rods, the main crossbeam is prevented from breaking due to excessive local stress, thus improving its overall load-bearing capacity. The connecting railings strengthen the coordinated force distribution between the tower head and the crossbeam. Multiple connecting railings form a rigid connection between the tower head sub-beam and the main crossbeam, transferring the upper load borne by the tower head sub-beam to the main crossbeam, while limiting the relative displacement between them, reducing stress concentration at the connection points, and enhancing the overall stability of the tower head and crossbeam system.

[0019] The present invention is further configured such that the fourth reinforcing support mechanism includes a plurality of horizontal and diagonal support rods assembled between the inner curved arm main beam and the outer curved arm main beam.

[0020] The above technical solution involves multiple horizontal and diagonal supports distributed at intervals along the extension directions of the inner and outer curved arm main beams. The horizontal supports are assembled horizontally, with both ends fixedly connected to the inner and outer curved arm main beams, respectively. The diagonal supports are assembled in an inclined direction, with both ends also connected to the inner and outer curved arm main beams, and cooperate with the horizontal supports to form a grid-like support structure between the inner and outer curved arms. The horizontal supports mainly bear the horizontal force between the inner and outer curved arms, limiting their relative displacement in the horizontal direction. The diagonal supports, through their inclination angle, transfer the vertical load between the inner and outer curved arm main beams, forming an oblique force distribution path.

[0021] In summary, this utility model has the following beneficial effects: 1. This utility model utilizes multiple reinforcing support structures, including a first reinforcing support mechanism between the tower corner main beam and the tower corner crossbeam, a fourth reinforcing support mechanism between the inner curved arm main beam and the outer curved arm main beam, a second reinforcing support mechanism between the two outer curved arm main beams, a third reinforcing support mechanism between the two inner curved arm main beams, and a connection mechanism between the two crossarm connecting beams. These structures comprehensively disperse and transfer loads from multiple key parts such as the tower corner, curved arm, and crossarm, effectively avoiding local stress concentration and greatly improving the overall load-bearing capacity of the tower. This allows it to better cope with complex loads such as conductor self-weight, icing, and strong winds.

[0022] 2. This utility model adopts stable structural forms such as cross members in each reinforcing support mechanism. For example, the first connecting rod and the second connecting rod are cross-arranged in the second reinforcing support mechanism, and the first diagonal brace and the second diagonal brace are cross-arranged in the connecting mechanism. This forms a stable truss structure system. This structural system enables the tower to maintain good structural stability when bearing loads, and it is not easy to deform or collapse. It effectively ensures the safety and stability of power transmission, and the structural stability is greatly enhanced.

[0023] 3. Through the structural design of components such as the tower corner main beam, combined with the enhancement of the overall structural stability by various strengthening support mechanisms, this utility model enables the iron tower to adapt well to different terrain environments. It can also play a stable role in the construction of power transmission lines in complex terrains such as mountains and hills, thus expanding the application scenarios of iron towers and improving terrain adaptability.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A high-load-bearing truss tower includes four rectangularly arranged corner main beams 1. A corner crossbeam 2 is fixedly connected to the top of each corner main beam 1. A first reinforcing support mechanism 3 is provided between the corner main beams 1 and the corner crossbeams 2. An inner curved arm main beam 4 is fixedly connected to the top of each corner main beam 1. A tower head base 5 is assembled between the four inner curved arm main beams 4. A crossbeam main beam 6 is fixedly connected to both ends of the tower head base 5. Outer curved arm main beams 7 are symmetrically assembled between the crossbeam main beams 6 and the inner curved arm main beams 4. A second reinforcing support mechanism 8 is provided between two outer curved arm main beams 7, and a third reinforcing support mechanism 9 is provided between two inner curved arm main beams 4. A tower head sub-beam 10, which is fixedly connected to the tower head base 5, is symmetrically arranged on the top of the main crossbeam 6. Three hanging points 18 are fixedly connected to the surfaces of the tower head base 5 and the tower head sub-beam 10, respectively. A crossbeam connecting beam 11 is assembled at one end of the tower head sub-beam 10 and one end of the main crossbeam 6. A connecting mechanism 12 is arranged between the two crossbeam connecting beams 11. A fourth reinforcing support mechanism 13 is assembled between the inner curved arm main beam 4 and the outer curved arm main beam 7. This is achieved through the first reinforcing support mechanism 3 between the tower corner main beam 1 and the tower corner crossbeam 2, the fourth reinforcing support mechanism 13 between the inner curved arm main beam 4 and the outer curved arm main beam 7, and the second reinforcing support mechanism between the two outer curved arm main beams 7. The tower features multiple reinforced support structures, including mechanism 8, the third reinforcing support mechanism 9 between the two inner curved arm main beams 4, and the connecting mechanism 12 between the two crossarm connecting beams 11. These structures comprehensively distribute and transfer loads from multiple key parts such as the tower corners, curved arms, and crossarms, effectively avoiding local stress concentration and greatly improving the overall load-bearing capacity of the tower. This allows it to better cope with complex loads such as conductor self-weight, icing, and strong winds. Each reinforced support mechanism employs stable structural forms such as intersecting members. For example, in the second reinforced support mechanism 8, the first connecting rod 81 and the second connecting rod 82 are intersected, and in the connecting mechanism 12, the first diagonal brace 12... The intersecting arrangement of the first and second diagonal braces 122 forms a stable truss structure system. This structure system enables the tower to maintain good structural stability when bearing loads, making it less prone to deformation or collapse. This effectively ensures the safety and stability of power transmission, significantly enhancing structural stability. Through the structural design of components such as the main beam 1 at the tower corner, combined with the enhancement effect of various strengthening support mechanisms on the overall structural stability, the tower can adapt well to different terrain environments. It can also play a stable role in the construction of power transmission lines in complex terrains such as mountains and hills, expanding the application scenarios of the tower and improving its terrain adaptability.

[0028] refer to Figure 7In this application, point A is the location for installing the side conductor, point B is the location for installing the middle conductor, and point C is the location for installing the ground wire. The side conductor corresponding to point A is the side phase conductor: in a transmission line, the side phase conductor is located on both sides of the crossarm of the tower, and its main function is to transmit electrical energy, delivering the electrical energy generated by the power plant to various power consumption areas. The middle conductor corresponding to point B is the middle phase conductor: the middle phase conductor is located in the middle of the crossarm of the tower, and it also undertakes the function of transmitting electrical energy. In a three-phase transmission system, the middle phase conductor and the side phase conductor together form a three-phase circuit to ensure stable power transmission. The ground wire corresponding to point C is the overhead ground wire, also called the lightning protection wire. It is generally erected on the top of the tower, and its main function is to prevent the transmission line from being struck by lightning. When there is lightning, the overhead ground wire can conduct the lightning current into the ground, thereby protecting the conductors and power equipment below from the damage of lightning overvoltage and ensuring the safe and stable operation of the transmission line.

[0029] refer to Figure 1 and Figure 2 The first reinforcing support mechanism 3 includes a tower corner inclined beam 31 fixedly connected between the tower corner main beam 1 and the tower corner crossbeam 2. Horizontal support rods 32 and inclined support rods 33 are assembled between the tower corner inclined beam 31 and the tower corner main beam 1. Multiple horizontal support rods 32 and inclined support rods 33 are used. By setting up the tower corner inclined beam 31, horizontal support rods 32 and inclined support rods 33, the load borne by the tower corner crossbeam 2 is directly transferred to the tower corner main beam 1 through the tower corner inclined beam 31, forming the main force path. Multiple horizontal support rods 32 and inclined support rods 33 further disperse the load, transferring the local stress between the tower corner inclined beam 31 and the tower corner main beam 1 to the surrounding members, avoiding stress concentration in a single area. The overall structure enhances the rigidity of the tower corner area through multi-node connections, reduces deformation at the connection between the tower corner main beam 1 and the tower corner crossbeam 2, and improves the overturning resistance of the tower base. This structure achieves the characteristics of "clear force distribution and simple connection," simplifying assembly while strengthening the overall load-bearing capacity of the tower corner area through the collaborative bearing of multiple members.

[0030] refer to Figure 1 and Figure 2A first support rod 14 is installed between the tower corner beam 2 and the inner curved arm main beam 4, and a second support rod 15 is installed between the first support rod 14 and the tower corner main beam 1. By setting the first support rod 14 and the second support rod 15, with the two ends of the first support rod 14 respectively installed on the tower corner beam 2 and the inner curved arm main beam 4, an oblique connection is formed between the tower corner beam 2 and the inner curved arm main beam 4. The two ends of the second support rod 15 are respectively installed on the middle part of the first support rod 14 and the tower corner main beam 1, so that the first support rod 14, the second support rod 15, and the tower corner main beam 1 form a stable triangular structure. The first support rod 14, as the main force transmission component, transfers the upper load borne by the inner curved arm main beam 4 to the tower corner beam 2, forming a longitudinal force transmission path from the inner curved arm to the tower corner. The second support rod 15, together with the first support rod 14 and the tower corner main beam 1, forms a triangular structure, which enhances the stability of the first support rod 14 and prevents it from bending or swaying laterally under load. The two work together to distribute the load of the upper structure to the tower corner main beam 1, reduce stress concentration at the connection between the tower corner beam 2 and the inner curved arm main beam 4, and improve the overall load-bearing capacity of the upper and lower connection areas of the tower body.

[0031] Referring to reference 3, the second reinforcing support mechanism 8 includes multiple first connecting rods 81 and second connecting rods 82 symmetrically assembled between two outer curved arm main beams 7. The first connecting rods 81 and second connecting rods 82 are arranged in a cross configuration. By arranging the first connecting rods 81 and second connecting rods 82, multiple first connecting rods 81 and second connecting rods 82 are symmetrically distributed, with their ends respectively assembled between two oppositely arranged outer curved arm main beams 7. The first connecting rods 81 and second connecting rods 82 intersect each other to form an "X" shape structure. The intersection points are fixed by bolts or welding, forming multiple sets of crosses. The supporting unit, with its intersecting first connecting rod 81 and second connecting rod 82, rigidly connects the two outer curved arm main beams 7 into a whole, forming a frame structure with stronger lateral stiffness in the outer curved arm area. This effectively resists the lateral forces generated by horizontal wind loads or conductor tension. The symmetrically distributed multiple sets of intersecting units can evenly transfer the load borne by the outer curved arm main beam 7 to both sides, avoiding deformation caused by excessive force on one side. The "X"-shaped intersecting structure disperses the load through axial force distribution of the rods, reducing the bending stress of the outer curved arm main beam 7 and improving the overall deformation resistance and load-bearing capacity of the curved arm area.

[0032] refer to Figure 1 and Figure 2The third reinforcing support mechanism 9 includes multiple first reinforcing rods 91 and second reinforcing rods 92 symmetrically assembled between the two inner curved arm main beams 4. The first reinforcing rods 91 and second reinforcing rods 92 are arranged in a cross configuration. A third reinforcing rod 93 is assembled between the first reinforcing rods 91 and second reinforcing rods 92 and the inner curved arm main beam 4. By setting the first reinforcing rods 91, second reinforcing rods 92 and third reinforcing rods 93, the multiple first reinforcing rods 91 and second reinforcing rods 92 are symmetrically distributed, with their two ends respectively assembled between the two opposite inner curved arm main beams 4, and the two intersecting to form an "X" shape structure. The intersection points are usually connected by bolts. One end of the third reinforcing rod 93 is connected to the first reinforcing rod 91. The third reinforcing rod 93 intersects with the second reinforcing rod 92 at one end, and is then assembled to the inner curved arm main beam 4 at the other end. This allows the third reinforcing rod 93, the inner curved arm main beam 4, and the intersecting first reinforcing rod 91 and second reinforcing rod 92 to form multiple triangular stable units. The intersecting first reinforcing rod 91 and second reinforcing rod 92 connect the two inner curved arm main beams 4 into a whole, which can transmit horizontal loads in both directions and prevent the inner curved arm main beam 4 from lateral displacement or torsion due to unilateral force. The third reinforcing rod 93 strengthens the stability of the intersection node through the triangular structure, and directly transmits the load borne by the first reinforcing rod 91 and second reinforcing rod 92 to the inner curved arm main beam 4, shortening the force transmission path and reducing stress concentration at the intersection.

[0033] refer to Figure 5 The connecting mechanism 12 includes multiple first diagonal braces 121 and second diagonal braces 122 symmetrically assembled between two crossbeam connecting beams 11. The first diagonal braces 121 and second diagonal braces 122 are arranged in a cross configuration. By arranging the first diagonal braces 121 and second diagonal braces 122, the multiple first diagonal braces 121 and second diagonal braces 122 are symmetrically distributed, with their ends fixedly assembled to two oppositely arranged crossbeam connecting beams 11. The first diagonal braces 121 and second diagonal braces 122 intersect each other to form an "X" shape. The intersection points are connected by connectors such as... The beams are bolted together and are located in the space between the two crossarm connecting beams 11. Together with the crossarm connecting beams 11, they form a closed load-bearing frame. The first diagonal brace 121 and the second diagonal brace 122, which are arranged in a cross configuration, rigidly connect the two crossarm connecting beams 11 to form a laterally stable structure. This structure effectively resists the horizontal thrust generated by conductor tension, wind load, etc., and prevents the crossarm connecting beams 11 from undergoing lateral deformation or misalignment. The symmetrically distributed multiple sets of "X"-shaped structures can evenly distribute the load, so that the force borne by the crossarm connecting beams 11 can be transmitted bidirectionally along the diagonal braces, avoiding local stress concentration.

[0034] refer to Figure 1 and Figure 4The main crossbeam 6 is internally fitted with multiple cross-arranged tension rods 16. Multiple connecting railings 17 are installed between the tower head sub-beam 10 and the main crossbeam 6. The tension rods 16 are arranged cross-shaped inside the main crossbeam 6, with both ends fixedly connected to the inner sidewalls of the main crossbeam 6, forming an "X"-shaped or grid-like internal support structure. The connecting railings 17 are respectively fitted to the sides of the tower head sub-beam 10 and the top of the main crossbeam 6, evenly distributed along the connecting edges, forming a triangular auxiliary support together with the tower head sub-beam 10 and the main crossbeam 6. The tension rods 16 reinforce the main crossbeam 6. The inherent rigidity of beam 6 and the cross-arranged tension bars 16 can effectively resist the tensile deformation and bending stress generated by the main beam 6 under the action of conductor load. By dispersing the load through the axial force of the bars, the main beam 6 of the crossarm is prevented from breaking due to excessive local stress, thus improving its overall load-bearing capacity. The connecting railings 17 strengthen the coordinated force bearing between the tower head and the crossarm. Multiple connecting railings 17 form a rigid connection between the tower head sub-beam 10 and the main beam 6 of the crossarm, transferring the upper load borne by the tower head sub-beam 10 to the main beam 6 of the crossarm, while limiting the relative displacement between the two, reducing stress concentration at the connection point, and enhancing the overall stability of the tower head and crossarm system.

[0035] refer to Figure 1 The fourth reinforcing support mechanism 13 includes multiple horizontal support rods 131 and diagonal support rods 132 assembled between the inner curved arm main beam 4 and the outer curved arm main beam 7. By setting the horizontal support rods 131 and diagonal support rods 132, the multiple horizontal support rods 131 and diagonal support rods 132 are distributed at intervals along the extension direction of the inner curved arm main beam 4 and the outer curved arm main beam 7. The horizontal support rods 131 are assembled in the horizontal direction, and their two ends are fixedly connected to the inner curved arm main beam 4 and the outer curved arm main beam 7 respectively. The diagonal support rods 132 are assembled in the inclined direction, and their two ends are also connected to the inner curved arm main beam 4 and the outer curved arm main beam 7. They cooperate with the horizontal support rods 131 to form a grid-like support structure between the inner and outer curved arms. The horizontal support rods 131 mainly bear the horizontal force between the inner and outer curved arms and limit the relative displacement of the two in the horizontal direction. The diagonal support rods 132 transmit the vertical load between the inner curved arm main beam 4 and the outer curved arm main beam 7 through the inclined angle, forming an oblique force diversion path.

[0036] Brief description of the usage process: Through the first reinforcing support mechanism 3 between the tower corner main beam 1 and the tower corner crossbeam 2, the fourth reinforcing support mechanism 13 between the inner curved arm main beam 4 and the outer curved arm main beam 7, the second reinforcing support mechanism 8 between the two outer curved arm main beams 7, the third reinforcing support mechanism 9 between the two inner curved arm main beams 4, and the connection mechanism 12 between the two crossarm connecting beams 11, etc., a radial truss similar to wings is formed by the arrangement of multi-angle members. The load is distributed and transferred in all directions from multiple key parts such as the tower corner, curved arm, and crossarm, effectively avoiding local stress concentration, greatly improving the overall load bearing capacity of the tower, and enabling it to better cope with the complex loads such as conductor self-weight, icing, and strong winds.

[0037] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
