Description

Technical Field

[0001] This utility model relates to the field of wire tensioner technology, specifically a multi-functional wire tensioner for power transmission and transformation lines. Background Technology

[0002] Transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the transmission line via circuit breakers and other control equipment. Structurally, transmission lines are divided into overhead transmission lines and cable lines. A wire tensioner is used to tighten conductors during the installation of overhead lines. Wire tensioners are categorized into hand-operated (lever) hoists, ratchet tensioners, and double-hook tensioners. To use a wire tensioner, first loosen the wire rope or galvanized iron wire on the tensioner and secure it to the crossarm. Clamp the conductor with wire clamps and then operate the special wrench. Wire tensioners can improve safety during the lifting of goods. Turnbuckles are used to tighten wire ropes and also adjust the tension. The OO type is used for applications where disassembly is infrequent, the CC type for applications where disassembly is frequent, and the CO type for applications where one end is frequently disassembled while the other end is not.

[0003] Existing wire tensioners are exposed to the outdoors during operation, which can easily cause the threaded rods of the tensioner to rust. When disassembling and replacing the tensioner, it is easy to strip the threads and make it inconvenient to rotate. Lubricant needs to be carried with you when you are outdoors. Therefore, we have proposed a new wire tensioner. Utility Model Content

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0026] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] In related technologies, when the wire tensioner is exposed to the outdoors during operation, the threaded rod of the wire tensioner is prone to rusting. When disassembling and replacing the wire tensioner, it is easy to strip the threads and make it inconvenient to rotate. Lubricant needs to be carried with you when you are outdoors.

[0028] To address some of the problems in the related technologies, this application provides a multi-functional tensioner for power transmission and transformation lines. When needed, a baffle 14 connected by a torsion spring hinge 15 is simply installed on both sides of the hub body 11 to prevent the threads of the internal threaded rod 12 from rusting.

[0029] This application is described below with reference to the accompanying drawings and specific embodiments:

[0030] Combination Figures 1-4 This application provides a multi-functional wire tensioner for power transmission and transformation lines, including a wire tensioning device 1; the wire tensioning device 1 includes: a coil body 11 with threaded rods 12 threaded to both ends; a connector 13 disposed at one end of the threaded rods 12; a baffle 14 disposed on the outer side wall of the coil body 11; and a torsion spring hinge 15 connecting the baffle 14 and the coil body 11.

[0031] When in use, first connect the wire or steel wire rope to the connector 13 on the threaded rod 12, then rotate the turnbuckle 11 to move the threaded rod 12, which is threaded to the turnbuckle 11, inward to tighten the wire or steel wire rope. When the turnbuckle 11 fixes the wire and steel wire rope in the air, the baffles 14 on both sides flip down to reduce the entry of rainwater in rainy weather, which could cause the internal thread structure to rust and become difficult to disassemble. Rust on the external threads will not hinder the rotation of the threaded rod 12. The baffles 14 are connected to the turnbuckle 11 through the torsion spring hinge 15 and have the force to rotate downward, fitting snugly against the turnbuckle 11.

[0032] Specifically, the connector 13 can be either hook-shaped or loop-shaped, and the torsion spring hinge 15 is a hinge with a torsion spring structure.

[0033] In some embodiments, the inner wall of the baffle 14 is provided with a magnetic block 141 that cooperates with the flower-shaped body 11. The baffle 14 can be attracted to the flower-shaped body 11 by the magnetic block 141.

[0034] In some embodiments, a fixing groove 111 is provided at the top of the flower-shaped body 11, and a column 17 is disposed inside the fixing groove 111. The column 17 is inserted into the fixing groove 111, making it convenient for workers to rotate the flower-shaped body 11 via the column 17.

[0035] In some embodiments, a nut 171 is threaded onto the outer wall of the column 17. The two nuts 171 secure the column 17 to the turnbuckle 11 for easy replacement.

[0036] In some embodiments, a gasket 172 is fitted on the outer wall of the column 17, and the gasket 172 has a rectangular structure. The gasket 172 can increase the friction between the nut 171 and the nut body 11, and can also rotate and misalign, limiting and blocking the baffle 14 from the top to prevent the baffle 14 from rotating upward.

[0037] In some embodiments, a rod 18 is provided on one side of the column 17. The bottom of the rod 18 has a slot 181 that engages with the column 17, and the outer side wall of the rod 18 is provided with an anti-slip sleeve 182. The rod 18 is inserted into the column 17 through the slot 181 at the bottom, which further facilitates the rotation of the turntable 11, makes it convenient for workers to carry, and the anti-slip sleeve 182 makes it easy for workers to grip the rod 18.

[0038] In some embodiments, a limiting block 16 is provided at the other end of the threaded rod 12, and the limiting block 16 is connected to the threaded rod 12 by bolts. The limiting block 16 is fixed to the threaded rod 12 by bolts, which can prevent the threaded rod 12 from turning out, providing double mechanical protection and preventing the turnbuckle 11 from falling off. In addition, the gap between the limiting block 16 and the fixing groove 111 can accommodate a hex wrench.

[0039] In some embodiments, a rubber pad 161 is provided on one side of the limiting block 16. The rubber pad 161 can reduce the friction between the threaded rod 12 and the fixing groove 111, and also prevent the bolt from being exposed.
