Description

Technical Field

[0001] This utility model relates to the field of iron tower accessories technology, and more specifically, to an iron accessory for a power transmission line tower. Background Technology

[0002] Transmission line towers are an important component of power transmission systems, used to support high-voltage transmission lines. Iron fittings are plate-shaped connecting hardware that connects several insulator strings or assembles multiple load-bearing branches into a whole. As a key component of the tower, they perform functions such as connection, fixation, protection, and strengthening of the structure.

[0003] Patent CN210636905U discloses a steel tower accessory. The cable is placed in a first groove at the top of a lower plate, and an upper plate is slidably connected to a groove on the lower plate via a slider. Bolts are passed through through holes in the upper plate and threaded holes in the lower plate, and connected to nuts to secure the upper and lower plates. Simultaneously, the first and second grooves clamp and fix the cable. A protective baffle prevents rainwater from entering the lower plate, and a drainage groove is provided at the bottom of the lower plate to drain any infiltrated rainwater. However, this steel tower accessory can only clamp and fix one bundle of cables, making it unsuitable for multiple bundles of cables laid side-by-side. Furthermore, although a drainage groove is provided, it lacks an outward water guiding structure, causing water to easily accumulate and hinder drainage, still resulting in some degree of surface corrosion to the cables. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide an iron accessory for a power transmission line tower.

[0005] A type of iron fitting for a transmission line tower includes an upper fitting plate and a lower fitting plate that interlock with each other; the upper fitting plate includes an upper arc plate and upper fixing plates fixed to both sides thereon, and the lower fitting plate includes a lower arc plate and auxiliary fixing plates and a lower fixing plate fixed to both sides thereon.

[0006] It also includes connecting fasteners that pass through the upper fixing plate, auxiliary fixing plate and lower fixing plate on the same side;

[0007] The upper fixing plate, auxiliary fixing plate and lower fixing plate are movably connected to a limiting member. When the limiting member is perpendicular to the upper arc plate or the lower arc plate, it is used to connect two adjacent upper plates or two lower plates.

[0008] Furthermore, the upper arc plate is an arc-shaped plate with the opening direction facing downward, and the inner wall of the upper arc plate is provided with a plurality of upper grooves.

[0009] Furthermore, the lower arc plate is an arc-shaped plate with the opening direction facing upward, and the inner wall of the lower arc plate is provided with a plurality of lower grooves and a plurality of oblique grooves, the oblique grooves penetrating through a plurality of adjacent lower grooves.

[0010] Furthermore, a drainage groove is provided at the bottom end of the inner wall of the lower arc plate, and the drainage groove is connected to each of the lower grooves and each of the inclined grooves; the drainage groove is provided with a plurality of drainage holes.

[0011] Furthermore, the upper fixing plate has an upper receiving groove and a first through hole, which penetrates the upper receiving groove.

[0012] Furthermore, the auxiliary fixing plate has an auxiliary receiving groove and a second through hole, which penetrates the auxiliary receiving groove.

[0013] Furthermore, the lower fixing plate has a lower receiving groove and a third through hole, which penetrates the lower receiving groove.

[0014] Furthermore, the limiting member is placed within the upper receiving groove, the auxiliary receiving groove, and the lower receiving groove.

[0015] Furthermore, the first through hole, the second through hole, and the third through hole overlap vertically;

[0016] The limiting member has a fourth through hole, which overlaps vertically with the first through hole, the second through hole and the third through hole.

[0017] Furthermore, the connecting fastener is a bolt.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] The iron fittings on this transmission line tower are designed with limiting components, allowing two adjacent sets of iron fittings to be connected side-by-side. When multiple cables need to be laid side-by-side, simply rotate the limiting component to be perpendicular to the upper or lower clamping plate, and then insert its free end into the receiving groove of another set of iron fittings. With the through-hole positioning of the connecting fasteners, side-by-side laying can be achieved, improving the versatility and flexibility of the iron fittings and adapting to various cable laying requirements.

[0020] The iron fittings of this transmission line tower have been optimized with a drainage structure to prevent cable corrosion. Multiple drainage holes are located at the bottom of the drainage ditch, allowing water to drain directly to the outside of the iron fittings. This effectively prevents water from accumulating inside the drainage ditch, reduces the chance of cables coming into contact with water, better protects the cables, and extends their service life.

[0021] Furthermore, the iron fittings of this transmission line tower are connected using multi-layered fixing plates, namely an upper fixing plate, an auxiliary fixing plate, and a lower fixing plate, along with connecting fasteners, resulting in a more stable connection structure. At the same time, the design of the limiting components further enhances the reliability of the connection, especially when multiple cable bundles are laid side-by-side, effectively preventing loosening and displacement between the iron fittings.

[0022] Furthermore, the iron fittings of this transmission line tower have a simple connection method, requiring only the upper and lower plates to be fixed with bolts. At the same time, the rotation and insertion of the limiting components are simple and quick, simplifying the installation and maintenance process. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] like Figures 1-2 As shown, this embodiment provides an iron accessory for a transmission line tower, including an upper and lower mating plate that interlock. The upper mating plate includes an upper arc plate 1 and upper fixing plates 2 fixed to its two sides. The lower mating plate includes a lower arc plate 3 and auxiliary fixing plates 4 and lower fixing plates 5 fixed to its two sides. It also includes a connecting fastener 6 that passes through the upper fixing plate 2, auxiliary fixing plate 4, and lower fixing plate 5 on the same side. A limiting member 7 is movably connected within the upper fixing plate 2, auxiliary fixing plate 4, and lower fixing plate 5. When the limiting member 7 is perpendicular to the upper arc plate 1 or the lower arc plate, it is used to connect two adjacent upper mating plates or two lower mating plates.

[0042] In this embodiment, as Figures 1-6 As shown, in the upper plate, the upper arc plate 1 and the upper fixing plates 2 on both sides are an integral structure. The upper arc plate 1 is an arc-shaped plate with its opening direction facing downward, and the inner wall of the upper arc plate 1 is provided with several parallel upper grooves 11. In the lower plate, the lower arc plate 3 and the auxiliary fixing plates 4 and lower fixing plates 5 on both sides are an integral structure; the lower arc plate 3 is an arc-shaped plate with its opening direction facing upward, and the inner wall of the lower arc plate 3 is provided with several lower grooves 31 and several oblique grooves 32, with the oblique grooves 32 penetrating through multiple adjacent lower grooves 31. When the upper plate and the lower plate are fastened together, the upper grooves 11 and the lower grooves 31 are connected.

[0043] A drainage groove 33 is also provided at the bottom of the inner wall of the lower arc plate 3. The drainage groove is connected to each recess 31 and each inclined groove 32. Several drainage holes 34 are also provided in the drainage groove 33 to drain water to the outside.

[0044] In this embodiment, in the upper plate, upper fixing plates 2 are fixedly connected to both sides of the upper arc plate 1. The upper fixing plate 2 has an upper receiving groove 21 and a first through hole 22, which penetrates the upper receiving groove 21.

[0045] In the lower plate, the auxiliary fixing plate 4 has an auxiliary receiving groove 41 and a second through hole 42, which penetrates the auxiliary receiving groove 41.

[0046] The lower fixing plate 5 has a lower receiving groove 51 and a third through hole 52, which passes through the lower receiving groove 51. The first through hole 22, the second through hole 42 and the third through hole 52 overlap vertically.

[0047] In this embodiment, two first through holes 22 are provided at one upper receiving groove 21 of the upper fixing plate 2. Two second through holes 42 are provided at one auxiliary receiving groove 41 of the auxiliary fixing plate 4. Two third through holes 52 are provided at one lower receiving groove 51 of the lower fixing plate 5.

[0048] The limiting member 7 is placed within the upper receiving groove 21, the auxiliary receiving groove 41, and the lower receiving groove 51. The upper receiving groove 21, the auxiliary receiving groove 41, and the lower receiving groove 51 have identical structures, with recesses in their middle sections to facilitate removal of the limiting member 7 from within. The limiting member 7 has a fourth through hole 71, which overlaps vertically with the first through hole 22, the second through hole 42, and the third through hole 52; the connecting fastener 6 is a bolt. The connecting fastener 6 passes sequentially through the first through hole 22, the second through hole 42, and the third through hole 52, enabling the upper and lower plates to be fastened together.

[0049] When using only one set of iron accessories for the transmission line tower provided in this embodiment, the limiting member is placed in each receiving groove, and the connecting fastener passes through the first through hole 22, the second through hole 42 and the third through hole 52, and also passes through the corresponding limiting member 7.

[0050] When it is necessary to use two sets of iron accessories for transmission line towers provided in this embodiment in parallel, such as Figures 7-9 As shown, one of the two side-by-side connecting fasteners 6 is removed first, and then the limiting member 7 is rotated so that the limiting member 7 is perpendicular to the upper and lower plates. At this time, the free end of the limiting member 7 is inserted into the respective receiving grooves of the other set of iron accessories. Then, the fastener is used to pass through the first through hole 22, the second through hole 42 and the third through hole 52 in sequence, while also passing through the corresponding limiting members 7. This allows the two sets of iron accessories to be used side by side, which is suitable for the side-by-side laying of two sets of cables.

[0051] When the upper and lower plates are fastened together, in order to enhance the sealing of the fastening point, a layer of rubber is attached to the lower end face of the upper fixing plate 1 of the upper plate, or a layer of rubber is attached to the upper end face of the auxiliary fixing plate 4 of the lower plate.

[0052] The iron fittings for the transmission line tower provided in this embodiment fix the cables by interlocking the upper and lower fittings. Connecting fasteners 6 pass through the upper fixing plate 2, auxiliary fixing plate 4, and lower fixing plate 5, tightly connecting the upper and lower fittings. The inner walls of the upper arc plate 1 and lower arc plate 3 are respectively provided with an upper groove 11 and a lower groove 31. When the upper and lower fittings are interlocked, the upper groove 11 and lower groove 31 are connected, and the inclined groove connects adjacent lower grooves, allowing water to flow into the drainage trough 33. The bottom end of the inner wall of the lower arc plate 3 is provided with a drainage trough 33, which is connected to the lower groove 31 and the inclined groove 32, and drains water through the drainage hole 34. Furthermore, the limiting member 7 can rotate and is perpendicular to the upper or lower fitting, used to connect two adjacent sets of iron fittings, enabling the parallel laying of multiple cable bundles.

[0053] The iron accessories for transmission line towers provided in this embodiment, through the design of the limiting member, enable two adjacent sets of iron accessories to be connected side by side. When multiple cables need to be laid side by side, simply rotate the limiting member to be perpendicular to the upper or lower mating plate, and then insert its free end into the receiving groove of another set of iron accessories. With the through-positioning of the connecting fastener 6, side by side laying can be achieved, improving the versatility and flexibility of the iron accessories and adapting to various cable laying requirements.

[0054] The iron fittings for the transmission line tower provided in this embodiment have an optimized drainage structure to prevent cable corrosion. Multiple drainage holes 34 are provided at the bottom of the drainage trough 33, allowing water to be directly discharged to the outside of the iron fittings. This effectively prevents water from accumulating in the drainage trough, reduces the chance of cables coming into contact with water, better protects the cables, and extends their service life.

[0055] The iron fittings for the transmission line tower provided in this embodiment are connected using multi-layer fixing plates, namely an upper fixing plate 2, an auxiliary fixing plate 4, and a lower fixing plate 5, along with connecting fasteners 6, resulting in a more stable connection structure. Simultaneously, the design of the limiting components further enhances the reliability of the connection, especially when multiple cables are laid side-by-side, effectively preventing loosening and displacement between the iron fittings.

[0056] The iron fittings for the transmission line towers provided in this embodiment have a simple connection method, requiring only the upper and lower plates to be fixed with bolts. Furthermore, the rotation and insertion of the limiting components are simple and quick, simplifying the installation and maintenance process.

[0057] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
