Description

Technical Field

[0001] This utility model relates to the field of power line tower technology, and in particular to an adjustable-angle power line tower connector. Background Technology

[0002] Existing methods for securing crossarms and pole bodies to transmission towers involve drilling and welding. However, with the adoption of composite materials for transmission towers, the tooling needs to be reconsidered. Currently, the tooling methods for crossarms of composite material towers, both domestically and internationally, often involve clamps and drilling. These methods are primarily used in low-voltage applications. Furthermore, because the fibers of composite materials are continuously arranged, drilling can affect the material's mechanical properties, leading to uneven stress on the tower and consequently impacting its service life.

[0003] Utility model patent CN202055599U discloses a composite material pole with tooling connectors. It includes a pole and crossarm made of insulating composite material, with pre-embedded connectors on the tower body and a flanged metal component at the root of the composite crossarm. The composite crossarm is connected to the tower body via the flanged metal component and the pre-embedded connectors, forming an integrated structure with the tower body. This design avoids drilling holes in the pole body for bolts, thus preventing damage to the fiber arrangement and reduced mechanical performance, while ensuring mechanical strength.

[0004] The composite material crossarm in the above scheme is connected to the tower body through metal parts and pre-embedded connectors. However, the angle of the metal parts cannot be adjusted. When the composite material crossarm needs to be connected to the tower at a certain angle, it is not convenient to make the connection. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable angle power line tower connector, which solves the problem that the angle of metal parts cannot be adjusted, and that it is inconvenient to connect composite material crossarms to towers when a certain angle is required.

[0006] To achieve the above objectives, this utility model provides an adjustable-angle power line tower connector, including a pre-embedded connector and an angle adjustment assembly. The angle adjustment assembly includes a fixed rod, a first mounting base, a telescopic rod, a second mounting base, and a metal component. One end of the fixed rod is fixedly connected to the pre-embedded connector, and the other end of the fixed rod is rotatably connected to the metal component. The first mounting base is fixedly connected to the pre-embedded connector and is spaced apart from the fixed rod. The second mounting base is slidably connected to the metal component, and the telescopic rod is disposed between the first mounting base and the second mounting base.

[0007] The telescopic rod includes an adjusting screw and a threaded cylinder. One end of the adjusting screw is rotatably connected to the first mounting base, and the other end of the adjusting screw is threadedly connected to the threaded cylinder. The other end of the threaded cylinder is rotatably connected to the second mounting base.

[0008] The telescopic rod further includes a rotating block, which is fixedly connected to the adjusting screw. The rotating block is located outside the adjusting screw and at one end of the adjusting screw near the first mounting base.

[0009] The second mounting base is provided with a T-shaped connecting block, and the metal part has a T-shaped connecting groove adapted to the T-shaped connecting block. The T-shaped connecting block is slidably disposed inside the T-shaped connecting groove.

[0010] The fixed rod has a spherical connecting ball at one end away from the pre-embedded connector. The metal part has a connecting seat with a spherical groove that matches the connecting ball. The connecting ball is movably disposed inside the spherical groove.

[0011] This utility model discloses an adjustable-angle power line tower connector. The fixed rod has two ends connected to a pre-embedded connector and a metal component, respectively. The metal component is rotatable relative to the fixed rod. The telescopic rod is extendable and retractable. One end of the telescopic rod is connected to the pre-embedded connector via a first mounting seat, and the other end is connected to the metal component via a second mounting seat. The second mounting seat can slide on the metal component, which is used to connect to a crossarm. When the telescopic rod extends or retracts, it causes the metal component to rotate relative to the fixed rod, thereby allowing the angle of the metal component to be adjusted for connection with the crossarm. This solves the problem that the angle of the metal component cannot be adjusted, making connection difficult when a certain angle is required for the composite material crossarm to be connected to the tower.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 , Figure 1 This is a structural schematic diagram of an adjustable-angle power line tower connector according to this utility model. Figure 2 This is a structural cross-sectional view of an adjustable-angle power line tower connector according to this utility model. Figure 3 This utility model relates to an adjustable-angle power line tower connector. Figure 2 The structural cross-sectional view at point AA.

[0019] This utility model provides an adjustable angle power line tower connector, including a pre-embedded connector 100 and an angle adjustment assembly. The angle adjustment assembly includes a fixed rod 210, a first mounting base 220, a telescopic rod, a second mounting base 230, and a metal part 240. The telescopic rod includes an adjusting screw 250, a threaded cylinder 260, and a rotating block 270.

[0020] In this specific embodiment, one end of the fixing rod 210 is fixedly connected to the pre-embedded connector 100, and the other end of the fixing rod 210 is rotatably connected to the metal part 240. The first mounting seat 220 is fixedly connected to the pre-embedded connector 100, and the first mounting seat 220 and the fixing rod 210 are spaced apart. The second mounting seat 230 is slidably connected to the metal part 240, and the telescopic rod is disposed between the first mounting seat 220 and the second mounting seat 230. The pre-embedded connector 100 is fixed to the tower by a pre-embedding method, forming an integral whole with the tower, avoiding drilling. The two ends of the fixing rod 210 are respectively connected to the pre-embedded connector 100 and the metal part 240. The metal part 240 can rotate relative to the fixing rod 210. The length of the telescopic rod can be extended or retracted. One end of the telescopic rod is connected to the pre-embedded connector 100 through the first mounting seat 220, and the other end of the telescopic rod is connected to the metal part 240 through the second mounting seat 230. The second mounting base 230 can slide on the metal part 240, which is used to connect the crossarm. When the telescopic rod extends or retracts, it can drive the metal part 240 to rotate relative to the fixed rod 210, thereby allowing the angle of the metal part 240 to rotate to facilitate connection with the crossarm. This solves the problem that the angle of the metal part 240 cannot be adjusted, which is inconvenient when the composite material crossarm needs to be connected to the tower at a certain angle.

[0021] Furthermore, one end of the adjusting screw 250 is rotatably connected to the first mounting base 220, and the other end of the adjusting screw 250 is threadedly connected to the threaded cylinder 260. The other end of the threaded cylinder 260 is rotatably connected to the second mounting base 230. The adjusting screw 250 can rotate relative to the first mounting base 220. When the adjusting screw 250 rotates, its length within the threaded cylinder 260 changes, thus adjusting the overall length of the telescopic rod and consequently adjusting the angle of the metal part 240. When the angle of the metal part 240 needs to be adjusted, the adjusting screw 250 is rotated, causing its length within the threaded cylinder 260 to change, thereby rotating the metal part 240 relative to the fixed rod 210 and adjusting its angle.

[0022] Specifically, the rotating block 270 is fixedly connected to the adjusting screw 250. The rotating block 270 is located outside the adjusting screw 250 and at the end of the adjusting screw 250 closest to the first mounting base 220. Since the adjusting screw 250 has a circular cross-section, making rotation inconvenient, the rotating block 270 is provided on the outside of the adjusting screw 250. The adjusting screw 250 can be rotated via the rotating block 270, facilitating its rotation and making it more convenient.

[0023] The second mounting base 230 is provided with a T-shaped connecting block 231, and the metal part 240 has a T-shaped connecting groove 241 adapted to the T-shaped connecting block 231. The T-shaped connecting block 231 is slidably disposed inside the T-shaped connecting groove 241. The T-shaped connecting block 231 can slide inside the T-shaped connecting groove 241, and the T-shaped connecting block 231 and the T-shaped connecting groove 241 cooperate with each other to realize the sliding connection between the second mounting base 230 and the metal part 240.

[0024] Additionally, the fixed rod 210 has a spherical connecting ball 211 at its end away from the pre-embedded connector 100. The metal part 240 has a connecting seat 242 with a spherical groove 243 that fits the connecting ball 211. The connecting ball 211 is movably disposed inside the spherical groove 243. The connecting ball 211 can roll inside the spherical groove 243. When the metal part 240 rotates relative to the fixed rod 210, the connecting ball 211 rolls inside the spherical groove 243, thereby realizing the rotation between the metal part 240 and the fixed rod 210.

[0025] When adjusting the angle of the metal part 240 using the adjustable-angle power line pole tower connector, the adjusting screw 250 can be rotated by the rotating block 270, causing the adjusting screw 250 to extend into the threaded cylinder 260 or move out of the threaded cylinder 260, thereby adjusting the length of the telescopic rod. When the length of the telescopic rod changes, it pushes or pulls the metal part 240 to rotate relative to the fixed rod 210, thereby realizing the angle adjustment of the metal part 240. This solves the problem that the angle of the metal part 240 cannot be adjusted, and that it is inconvenient to connect the composite material crossarm to the pole tower when a certain angle is required.

[0026] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that implementing all or part of the above embodiments and making equivalent changes in accordance with the claims of this application still fall within the scope of this application.
