Description

Technical Field

[0001] This utility model relates to the field of anti-vibration hammer installation technology, and in particular to a pole armor protection device. Background Technology

[0002] Cement poles have been widely used in the power and communications fields due to their significant advantages, such as saving a lot of steel, reducing line construction costs, being easy to operate and maintain, requiring less maintenance work, and having a long service life.

[0003] However, it also has disadvantages such as its large weight and inconvenience in transportation. Therefore, in places where transportation is inconvenient, spliced ​​cement poles are often used, with each segment typically 5, 6, 9 meters or longer. During on-site erection, the segments are then connected together using flange bolts or welding.

[0004] In existing technology, the joint ends of cement poles are equipped with flanges. During on-site construction, the two flanges are aligned and reinforced with bolts or by full welding, followed by surface anti-corrosion treatment. However, existing technology has the following problems: the flanges are directly exposed to the outside, making them susceptible to rainwater corrosion, leading to rust on the bolts, welds, and internal structure, and over time causing the cement to crack and fall off. This reduces wind resistance, making the poles highly susceptible to being blown down by strong winds.

[0005] Based on this, the present invention provides a protective armor for spliced ​​utility poles to improve the wind resistance of spliced ​​utility poles and prevent strong winds from blowing the poles down. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a protective armor for spliced ​​utility poles, thereby improving the wind resistance of spliced ​​utility poles and preventing them from being blown down by strong winds.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An armored protection device for a utility pole connection includes: an armored clamp, fixing lugs, lifting lugs, connecting bolts, EDPM foam, and anti-loosening nuts. The armored clamp consists of two symmetrically arranged cylindrical sections, forming a ring structure that wraps around the periphery of the pole connection point. Several fixing lugs and lifting lugs are provided, with the fixing lugs spaced apart on the longitudinal mating side of the cylindrical section sections and having through holes. Several lifting lugs are spaced apart on the top of the cylindrical section sections. The EDPM foam is fixed to the cylindrical section section near the pole connection point, with the EDPM foam layer in direct contact with the pole surface. One end of the connecting bolt passes through the fixing lug hole on one cylindrical section of the protective cover, and the other end passes through the fixing lug hole on the corresponding cylindrical section of the protective cover and is connected to the anti-loosening nut.

[0008] Preferably, the cylindrical section of the armor clamp is made of a steel plate with a height of 500mm and a thickness of 4mm; the curvature of the cylindrical section of the protective cover is similar to that of the utility pole.

[0009] Preferably, the cylindrical section of the protective cover has three fixing ears on each side of the docking side, and the distance between adjacent fixing ears is 100-150mm.

[0010] Preferably, the top of the cylindrical section cover is provided with two lifting lugs, which are arranged symmetrically.

[0011] Preferably, the connecting bolt is an external hexagonal bolt; the outer surface of the external hexagonal bolt and the anti-loosening nut is provided with a galvanized layer, the thickness of which is not less than 85μm.

[0012] Preferably, a silicone sealant layer is provided at the joint of the two cylindrical sections of the armor clamp and at the upper and lower edges where the armor clamp contacts the connecting pole, and the silicone sealant layer has a thickness of 2-3 mm.

[0013] Preferably, the outer surface of the armor clamp and the outer surface of the fixing ear are provided with a galvanized layer, and the thickness of the galvanized layer is not less than 85μm.

[0014] This utility model discloses a pole armor protection device with the following beneficial effects.

[0015] The system employs armored clamps on both sides of the connection point of the main body of the connecting pole for fixation and reinforcement. An EDPM foam layer is installed on the inner wall of the armored clamps to buffer the clamps when tightened by connecting bolts, thus preventing damage to the surface of the connecting pole. This also prevents water from flowing along the main body of the connecting pole into the armored clamps and avoids flange corrosion.

[0016] By using multiple fixing lugs and connecting bolts to apply pressure evenly, local stress concentration is avoided, extending the life of the pole. The clamping force of the connecting bolts can be finely adjusted according to the pole diameter. The armored clamps wrap around the flange connection of the connecting pole, which can improve the bending and torsional resistance and prevent the flange from deforming or cracking. The overall thickness of the armored clamps is controlled within the allowable range of the standard pole diameter. After tightening, it fits tightly against the pole, so there is no risk of foot injury or slippage when climbing the pole, and it does not add any additional obstacles to climbing the pole.

Example 1

[0029] Please refer to Figures 1 to 4 As shown, a protective armor device for connecting utility poles includes: an armor clamp 3, fixing lugs 6, lifting lugs 7, connecting bolts 4, EDPM foam 2, and anti-loosening nuts 5. The armor clamp 3 consists of two symmetrically arranged cylindrical sections of the protective cover, forming a ring structure that wraps around the periphery of the pole connection point. Several fixing lugs 6 and lifting lugs 7 are provided, with the fixing lugs 6 spaced apart on the longitudinal mating side of the cylindrical section protective cover and having through holes. Several lifting lugs 7 are spaced apart on the top of the cylindrical section protective cover. The EDPM foam 2 is fixed to the cylindrical section protective cover near the connecting utility pole, and the EDPM foam 2 layer is in direct contact with the surface of the connecting utility pole. The thickness of the EDPM foam 2 layer is 3-5 mm. One end of the connecting bolt 4 passes through the through hole of the fixing lug 6 on one cylindrical section of the protective cover, and the other end passes through the through hole of the fixing lug 6 on the corresponding cylindrical section of the protective cover and is connected to the anti-loosening nut 5. In this embodiment, the armor clamp 3 is made of Q235 carbon steel.

[0030] Preferably, in this embodiment, the cylindrical section of the armor clamp 3 is a steel plate with a height of 500mm and a thickness of 4mm; the curvature of the cylindrical section of the protective cover is similar to that of the pole.

[0031] This invention relates to an armored protection device for a utility pole. It employs armored clamps 3 on both sides of the connection point of the main body of the pole 1 for fixation and reinforcement. EDPM foam 2 layers are installed on the inner wall of the armored clamps 3. This cushions the clamps 3 when tightened by the connecting bolts 4, preventing damage to the surface of the pole. It also prevents water from flowing along the main body of the pole 1 into the interior of the armored clamps 3, thus avoiding flange corrosion.

[0032] By using multiple fixing lugs 6 and connecting bolts 4 to apply pressure evenly, local stress concentration is avoided, extending the life of the pole. The connecting bolts 4 can finely adjust the clamping force according to the pole diameter. The armor clamp 3 wraps around the flange connection of the connecting rod 1, which can improve the bending and torsion resistance and prevent the flange from deforming or cracking. The overall thickness of the armor clamp 3 is controlled within the allowable range of the standard diameter of the pole. After tightening, it fits tightly against the pole. When climbing the pole, there is no risk of foot injury or slippage at the contact surface of the foot buckle or safety belt, and no additional obstacles are added to climbing the pole. Example 2

[0033] Based on Example 1, such as Figure 5 As shown, preferably, in this embodiment, each side of the cylindrical section protective cover has three fixing ears 6, and the distance between adjacent fixing ears 6 is 100-150mm. Specifically, in this embodiment, the fixing ears 6 of one cylindrical section protective cover are located near the end edge, and the fixing ears 6 of the other cylindrical section protective cover are reserved with an installation gap of 20-30mm from the end edge, so that the two cylindrical section protective covers can be staggered and overlapped when installed on the connecting pole, effectively avoiding the joint seam being on the same plane, and improving the sealing performance and wind resistance of the overall structure.

[0034] Preferably, in this embodiment, the top of the cylindrical section cover is provided with two lifting lugs 7, which are arranged symmetrically. Example 3

[0035] Based on embodiments 1 and 2, as a preferred embodiment, in this embodiment, the connecting bolt 4 is an external hexagonal bolt; the outer surface of the external hexagonal bolt and the anti-loosening nut 5 is provided with a galvanized layer, and the thickness of the galvanized layer is not less than 85μm.

[0036] Preferably, in this embodiment, a silicone sealant layer is provided at the joint of the two cylindrical sections of the armor clamp 3 and at the upper and lower edges where the armor clamp 3 contacts the connecting pole. The silicone sealant layer has a thickness of 2-3 mm.

[0037] Preferably, in this embodiment, the outer surface of the armor clamp 3 and the outer surface of the fixing ear 6 are both provided with a galvanized layer, and the thickness of the galvanized layer is not less than 85μm.

[0038] In this embodiment, when installing the protective armor device for the connecting pole, construction workers need to climb the pole and install an auxiliary lifting clamp (not shown in the figure) above the flange connection of the connecting pole 1. It should be noted that the auxiliary lifting clamp is a common clamp with a welded lifting ring at the bottom, which is a common technical method and will not be described in detail here. After the auxiliary lifting clamp is installed on the pole, the construction workers adjust the rollers and lifting ropes, and then the ground construction workers drag the "protective armor device for the connecting pole" up to the installation position, i.e., the connecting pole. At the flange connection, after the "connecting pole armor protection device" reaches the installation position, the construction personnel on the pole will alternately attach the two cylindrical protective sections to the connecting pole 1. According to the diameter of the connecting pole 1, the clamping force will be evenly adjusted by applying pressure with the external hexagonal bolts until the pole is tightly gripped. Finally, a silicone sealant layer with a thickness of 2-3mm will be applied to the joint of the two cylindrical protective sections of the armor clamp 3 and the upper and lower edges where the armor clamp 3 contacts the connecting pole. After completion, the auxiliary hoisting clamp will be removed, and the installation will be completed.

[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
