Description

Technical Field

[0001] This utility model belongs to the field of pole reinforcement technology, specifically relating to a reinforcement device for utility poles. Background Technology

[0002] Cement poles are mainly composed of steel bars and concrete, hence they are also called reinforced concrete cement poles. They are mainly used as overhead line supports in industries such as power, communications, railways, and petroleum.

[0003] Existing cement poles, due to long-term use, are prone to cracking, cement peeling, and exposed steel bars due to wind and rain erosion, external impact, and aging. Especially at the joints between upper and lower sections, stress concentration makes them high-risk areas for breakage, seriously affecting the safe operation of the power grid.

[0004] Traditional utility pole joints are often fixed using ordinary flat iron clamps or single-layer steel plates. However, these clamps or plates only provide fixation at a single point or in a localized area, concentrating the stress on the bolt connection point. When the pole is subjected to external forces such as strong winds, ice accumulation, or vehicle impacts, the joint is prone to breakage due to stress overload, leading to the pole tilting or collapsing. This risk is exacerbated, especially in areas prone to typhoons and strong earthquakes.

[0005] In addition, traditional flat iron clamps or single-layer steel plates have insufficient tensile strength, requiring bolts or clamps to be replaced every 1-2 years on average, resulting in high maintenance costs; if a breakage accident occurs, the repair costs will be even higher, and it will also affect the reliability of power supply.

[0006] Finally, traditional clamps have fixed dimensions, but in actual engineering projects, the diameter of the poles can fluctuate within a certain range due to differences in production batches. As a result, clamps are prone to being "too loose" or "too tight". If the clamps are too loose, displacement will occur, and if the clamps are too tight, cracks will be generated by compressing the pole body, further reducing the structural stability. Utility Model Content

[0008] The technical effects to be achieved by this utility model are realized through the following technical aspects:

[0014] In some optional implementations, the first clamp assembly further includes a first stiffening plate and a second stiffening plate. The first stiffening plate is respectively disposed at both ends of the first clamp and is fixedly connected to the first clamp and the first wing plate respectively. The second stiffening plate is respectively disposed at both ends of the second clamp and is fixedly connected to the second clamp and the second wing plate respectively.

[0015] And / or, the second clamp assembly further includes a third stiffening plate and a fourth stiffening plate, wherein the third stiffening plate is respectively disposed at both ends of the third clamp member, and the third stiffening plate is fixedly connected to the third clamp member and the third wing plate respectively; the fourth stiffening plate is respectively disposed at both ends of the fourth clamp member, and the fourth stiffening plate is fixedly connected to the fourth clamp member and the fourth wing plate respectively.

[0016] In some alternative implementations, the first stiffening plate is welded and fixed to the first clamp and the first wing plate, and the second stiffening plate is welded and fixed to the second clamp and the second wing plate;

Furthermore, this force-bearing structure prevents external forces from concentrating on a single cross-section, but rather distributes them to multiple points on the upper and lower sections of the pole through the offset clamp assemblies and support arms, avoiding fracture at the joint due to localized stress overload.

[0026] In addition, multiple sets of first clamp assemblies located above the part to be reinforced and multiple sets of second clamp assemblies located below the part to be reinforced are staggered along the axial direction of the pole, which can limit the small deformation of the pole in the axial direction. Especially in the event of an earthquake or vehicle collision, the "step-like" constraint of the multi-level clamp assemblies can slow down the transmission of impact force and reduce the risk of the pole falling.

[0027] Multiple support arms are arranged radially and staggered along the pole to form 360° lateral support without blind spots. No matter which direction the external force is applied from, the corresponding support arms can quickly bear and disperse the force, thereby improving the torsional stiffness of the pole and making it suitable for outdoor environments with multiple wind directions and complex terrain.

[0028] Furthermore, the multiple clamp components are designed to be staggered along the axial direction of the pole, which can adapt to the slight curvature deviation of the pole surface. Through the staggered distribution of the clamp components, multiple points of contact are made with the curved surface of the pole, reducing single-point pressure and avoiding the "point contact" wear caused by the poor fit of traditional symmetrical clamps, thus protecting the integrity of the pole surface.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of this utility model.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0047] Example 1:

[0048] In order to solve the problems of insufficient tensile strength, poor seismic performance and low bending moment bearing capacity of the flat iron clamps or single-layer steel plates in the prior art, this embodiment provides a reinforcement device for utility poles.

[0049] Please see Figure 1 This embodiment provides a reinforcement device for utility poles, comprising: multiple sets of reinforcement components 10, each set of reinforcement components 10 including at least a first clamp assembly 11, a second clamp assembly 12, and two support arms 13. The first clamp assembly 11 is fixedly connected to the upper part 21 of the utility pole 20 to be reinforced, the second clamp assembly 12 is fixedly connected to the lower part 21 of the utility pole 20 to be reinforced, and the two support arms 13 are symmetrically arranged, with both ends of the support arms 13 fixedly connected to the first clamp assembly 11 and the second clamp assembly 12, respectively. The multiple sets of reinforcement components 10 are staggered along the axial direction of the utility pole 20, and the multiple support arms 13 are staggered along the radial direction of the utility pole 20.

[0050] In this embodiment, multiple sets of first clamp assemblies 11 located above the reinforcement section 21 of the pole 20 are offset along the axial direction of the pole 20, and multiple sets of second clamp assemblies 12 located below the reinforcement section 21 of the pole 20 are offset along the axial direction of the pole 20. These, along with multiple support arms 13 offset along the radial direction of the pole 20, form a "three-dimensional mesh" stress-bearing structure, improving the stress-bearing strength of the reinforcement device. Furthermore, this stress-bearing structure prevents external forces from concentrating on a single cross-section, instead distributing them to multiple points on the upper and lower sections of the pole 20 through the offset first clamp assemblies 11 and second clamp assemblies 12 and the support arms 13, thus preventing the pole 20 from breaking due to localized stress overload at the joints.

[0051] In addition, the multiple sets of first clamp assemblies 11 located above the part to be reinforced 21 and the multiple sets of second clamp assemblies 12 located below the part to be reinforced 21 are staggered along the axial direction of the pole 20, which can limit the small deformation of the pole 20 in the axial direction. Especially in the event of an earthquake or vehicle collision, the impact force can be reduced by the "stepped" constraint of the multi-level first clamp assemblies 11 and second clamp assemblies 12, thereby reducing the risk of the pole 20 falling over.

[0052] Multiple support arms 13 are arranged radially staggered along the pole 20 to form 360° lateral support without dead angles. No matter which direction the external force is applied from, the corresponding support arms 13 can quickly bear and disperse the force, thereby improving the torsional stiffness of the pole 20 and making it suitable for outdoor environments with multiple wind directions and complex terrain.

[0053] Furthermore, the multiple sets of first clamp assemblies 11 and second clamp assemblies 12 are designed to be staggered along the axial direction of the pole 20, which can adapt to the slight curvature deviation of the surface of the pole 20. Through the staggered distribution of the first clamp assemblies 11 and second clamp assemblies 12, multiple points of contact are made with the curved surface of the pole 20, reducing single-point pressure and avoiding the "point contact" wear caused by the poor local fit of the traditional symmetrical clamp, thus protecting the integrity of the pole surface.

[0054] In this preferred embodiment, the reinforcement component 10 is configured as at least three sets, and the three sets of reinforcement components 10 have the same structure.

[0055] Therefore, the three sets of first clamp assemblies 11 located above the part to be reinforced 21 and the three sets of second clamp assemblies 12 located below the part to be reinforced 21 are staggered along the axial direction of the pole 20, and the three sets of first clamp assemblies 11 and the three sets of second clamp assemblies 12 are respectively arranged in a "stepped" manner.

[0056] Given that each set of reinforcement components 10 includes two support arms 13, the reinforcement component 10 of this embodiment includes six support arms 13, which are arranged radially offset along the pole 20.

[0057] Preferably, the angle between two adjacent support arms 13 is the same along the circumference of the pole 20.

[0058] In this embodiment, multiple support arms 13 are distributed at equal angles along the circumference of the pole 20, which ensures that the force points of the pole 20 are evenly distributed in the circumference. No matter which direction the external force acts from, the load can be quickly transmitted and dispersed through the nearest support arm 13, avoiding deformation of the support arm 13 or local damage to the pole 20 due to excessive stress in a certain area caused by the concentration of force points.

[0059] Furthermore, the equiangular distribution allows the installation position of the support arm 13 to have a clear regularity, eliminating the need for complex measurement and positioning procedures. Construction personnel can quickly determine the installation point of each support arm 13 through simple angle division, reducing installation errors.

[0060] By combining multiple sets of first clamp assemblies 11 and multiple sets of second clamp assemblies 12 that are axially offset along the pole 20, a "three-dimensional grid" positioning system is formed, which further reduces the installation difficulty of the reinforcement device and shortens its installation time.

[0061] Based on the shape of the pole 20, the equally angled support arms 13 can form a "multi-point symmetrical clamping" effect with the first clamp assembly 11 and the second clamp assembly 12, which are respectively staggered at the top and bottom. The tension of each support arm 13 on the first clamp assembly 11 and the second clamp assembly 12 is uniform, ensuring that the first clamp assembly 11 and the second clamp assembly 12 are tightly attached to the surface of the pole 20, avoiding rainwater seepage or dust accumulation due to poor local attachment, and reducing local squeezing damage to the surface of the pole 20 caused by the first clamp assembly 11 and the second clamp assembly 12.

[0062] This embodiment is a preferred embodiment, and the specific structure of the first clamp assembly 11 has been optimized.

[0063] In this embodiment, as Figure 2-3 As shown, the first clamp assembly 11 includes a first clamp 111 and a second clamp 112. The first clamp 111 and the second clamp 112 are centrally symmetrically distributed. The first end of the support arm 13 is located between the mating ends of the first clamp 111 and the second clamp 112. The mating ends of the first clamp 111 and the second clamp 112 are fixedly connected by a first connector 14 that passes through the first clamp 111, the first end of the support arm 13, and the second clamp 112 in sequence.

[0064] In this embodiment, the first clamping member 111 and the second clamping member 112, which are centrally symmetrically distributed, form a complete ring structure after clamping together. The clamping force on the pole 20 is evenly distributed on the circumferential surface, avoiding excessive local pressure caused by uneven force, and ensuring that the first clamping member 11 fits tightly with the pole 20.

[0065] Preferably, the first clamp 111 is provided with a first wing plate 113 at both ends, and the second clamp 112 is provided with a second wing plate 114 at both ends. The first wing plate 113 and the second wing plate 114 located at the docking ends of the first clamp 111 and the second clamp 112 are arranged opposite to each other. The first end of the support arm 13 is located between the first wing plate 113 and the second wing plate 114. The first connector 14 passes through the first wing plate 113, the first end of the support arm 13 and the second wing plate 114 in sequence.

[0066] In addition, the first clamp assembly 11 also includes a first stiffening plate 115 and a second stiffening plate 116. The first stiffening plate 115 is respectively disposed at both ends of the first clamp member 111 and is fixedly connected to the first clamp member 111 and the first wing plate 113 respectively. The second stiffening plate 116 is respectively disposed at both ends of the second clamp member 112 and is fixedly connected to the second clamp member 112 and the second wing plate 114 respectively.

[0067] Specifically, the first stiffening plate 115 is welded and fixed to the first clamp 111 and the first wing plate 113, and the second stiffening plate 116 is welded and fixed to the second clamp 112 and the second wing plate 114.

[0068] In this embodiment, the first stiffening plate 115 is welded to both the first clamp 111 and the first wing plate 113, and the second stiffening plate 116 is welded to both the second clamp 112 and the second wing plate 114, enhancing the connection strength of each component and forming a triangular support unit of "clamp-stiffening plate-wing plate," significantly increasing the overall stiffness of the first clamp assembly 11. This improves the bending section modulus of the first clamp assembly 11, effectively resisting the deformation caused by bending moment at the connection of the pole 20. Combined with the support arm 13, this further enhances the overall bending moment bearing capacity.

[0069] The first connector 14 is a bolt. The first wing plate 113 and the second wing plate 114 provided at the mating end of the first clamp 111 and the second clamp 112 provide a stable force carrier for the connection of the first connector 14. When the first connector 14 is tightened, the first wing plate 113 and the second wing plate 114 can evenly transmit the tension to the first clamp 111, the first stiffening plate 115, the second clamp 112 and the second stiffening plate 116, avoiding the cracking of the weld point caused by the concentration of force at the end of the traditional clamp.

[0070] In this preferred embodiment, the first connector 14 uses a 6.8 grade bolt. The 6.8 grade bolt has a tensile strength ≥600MPa and a yield strength ≥480MPa, and can stably withstand a preload of 45N·m, ensuring that the connection between the first clamp assembly 11 and the second clamp assembly 12 and the support arm 13 does not loosen.

[0071] In addition, in this embodiment, the first clamp assembly 11, the second clamp assembly 12, the support arm 13 and the first connector 14 are all made of steel and their surfaces are all galvanized. The potential difference is extremely small, which can avoid electrochemical corrosion caused by contact between dissimilar metals and further ensure the long-term stability of the connection parts.

[0072] In this preferred embodiment, the second clamp assembly 12 has the same structure as the first clamp assembly 11.

[0073] Therefore, the second clamp assembly 12 includes a third clamp and a fourth clamp, which are centrally symmetrically distributed. The second end of the support arm 13 is located between the mating ends of the third clamp and the fourth clamp. The mating ends of the third clamp and the fourth clamp are fixedly connected by a second connector that passes through the third clamp, the second end of the support arm 13, and the fourth clamp in sequence.

[0074] Preferably, the third clamp is provided with a third wing plate at both ends, and the fourth clamp is provided with a fourth wing plate at both ends. The third wing plate and the fourth wing plate located at the docking end of the third clamp and the fourth clamp are arranged opposite to each other. The second end of the support arm 13 is located between the third wing plate and the fourth wing plate. The second connector passes through the third wing plate, the second end of the support arm 13 and the fourth wing plate in sequence.

[0075] In addition, the second clamp assembly 12 also includes a third stiffening plate and a fourth stiffening plate. The third stiffening plate is respectively disposed at both ends of the third clamp and is fixedly connected to the third clamp and the third wing plate respectively. The fourth stiffening plate is respectively disposed at both ends of the fourth clamp and is fixedly connected to the fourth clamp and the fourth wing plate respectively.

[0076] The third stiffening plate is welded and fixed to the third clamp and the third wing plate, and the fourth stiffening plate is welded and fixed to the fourth clamp and the fourth wing plate.

[0077] This embodiment is a preferred embodiment, and the first stiffening plate 115, the second stiffening plate 116, the third stiffening plate, and the fourth stiffening plate have the same structure.

[0078] The first stiffening plate 115 is triangular in shape, the contact edge between the first stiffening plate 115 and the first clamp 111 is an arc shape that matches the first clamp 111, and the contact edge between the first stiffening plate 115 and the first wing plate 113 is a straight surface that matches the first wing plate 113.

[0079] In this embodiment, the second clamp assembly 12 can achieve the same technical effect as the first clamp assembly 11.

[0080] This embodiment is a preferred embodiment, and the structure of the support arm 13 has been optimized.

[0081] In this embodiment, as Figure 4-5 As shown, the support arm 13 includes a first arm 131 and a second arm 132 arranged along the axial direction of the pole 20. The first arm 131 and the second arm 132 are connected at an angle, and the connecting end faces of the first arm 131 and the second arm 132 are parallel to the axis of the pole 20.

[0082] In this embodiment, the first arm 131 and the second arm 132 are connected at an acute angle, so that the support arm 13 forms a certain angle with the axis of the pole 20. Together with the first clamp assembly 11 and the second clamp assembly 12 set at the top and bottom, a diagonal support structure similar to a "truss" is formed. This support structure converts the longitudinal bending moment borne by the pole 20 joint into the axial tensile and compressive forces of the support arm 13, making the force transmission path shorter and more direct, thereby further improving the bending moment bearing capacity of the overall structure of the reinforcement device.

[0083] In addition, the two ends of the support arm 13 are twisted to form a first connecting part 133 and a second connecting part 134; the first connecting part 133 and the second connecting part 134 are arranged radially along the pole 20, the first connecting part 133 is fixedly connected to the first clamp assembly 11, and the second connecting part 134 is fixedly connected to the second clamp assembly 12.

[0084] In this embodiment, after the two ends of the support arm 13 are twisted at a certain angle, the contact surfaces of the first connecting part 133 and the second connecting part 134 with the surface of the pole 20 are precisely matched with the tilt angle of the surface of the pole 20, thereby reducing the fitting gap between the support arm 13 and the pole 20.

[0085] Furthermore, the two ends of the support arm 13 are flattened by fire bending to increase the contact area at the ends of the support arm 13. When connected with bolts, the pressure of the bolts on the first clamp 111 and the second clamp 112 can be distributed to prevent the first clamp 111 and the second clamp 112 from deforming due to excessive local stress, thus extending the service life of the first clamp 111 and the second clamp 112.

[0086] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0087] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0088] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0089] In this invention, unless otherwise expressly specified and limited, "above or below" the first feature may include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on" the first feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the first feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0090] Although the description of this utility model has been given in conjunction with the specific embodiments described above, it is obvious to those skilled in the art that many substitutions, modifications, and variations can be made based on the above description. Therefore, all such substitutions, modifications, and variations are included within the spirit and scope of the appended claims.
