Description

Technical Field

[0001] The present invention relates to the technical field of wire fixators, and particularly to a rotary self - adapting wire top - binding fixator and a construction method thereof. Background Art

[0002] In power transmission and distribution lines, the fixation between the wire and the insulator is a key link to ensure the safe and stable operation of the line. Traditional wire fixators have many deficiencies in practical applications.

[0003] Existing wire fixators (such as a pin - type porcelain insulator overhead wire fixator disclosed in Chinese invention patent CN204741244U) generally include a left clamp body and a right clamp body. Both the left clamp body and the right clamp body are provided with arc - shaped clamping parts adapted to the pin - type porcelain insulator, and both ends are provided with fixing holes. In addition, it also includes two pairs of arc - shaped clamping plates, and both ends of the two pairs of arc - shaped clamping plates are also provided with fixing holes. It clamps the left clamp body, the right clamp body, and the overhead wire through bolts. This structural design results in numerous components and a complex structure. In actual operation, when it is necessary to disassemble and assemble the wire, it is necessary to first remove 4 bolts, and then disassemble and assemble the left clamp body and the right clamp body respectively. This process is extremely cumbersome, consuming a large amount of time and manpower, and seriously affecting the installation, maintenance, and repair work efficiency of power lines.

[0004] In view of the above - mentioned defects of traditional wire fixators, there is an urgent need for a porcelain insulator top wire fixing device with a simple structure, few components, and convenient disassembly and assembly to meet the growing requirements of the power industry for efficient and convenient construction and maintenance. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a rotary self - adapting wire top - binding fixator, comprising: A snap ring, the snap ring is an overall annular structure adapted to the skirt cover at the top of the insulator. The middle part of the snap ring has a recessed surface formed by downward depression. The bottom of the snap ring on both sides of the recessed surface has a downward - extending pressing step, and the upper end surface of the snap ring has an upward - extending pressing step. A snap - fit groove for snap - fitting on the skirt cover of the insulator is formed between the downward - extending pressing step and the upward - extending pressing step; A wire pressing plate, the wire pressing plate is located above the snap ring and is connected to the snap ring through a fixing bolt.

[0006] Further, the two ends of the snap ring have fixing screw holes, and the two ends of the wire pressing plate are provided with fixing holes corresponding to the fixing screw holes.

[0007] Further, the bottom of the wire pressing plate has an embedding groove, and a pressing block is embedded in the embedding groove. The bottom of the pressing block has an arc - shaped pressing surface.

[0008] Furthermore, the top of the wire pressing plate has an arc surface or an inclined surface inclined toward two sides of the wire pressing plate.

[0009] Furthermore, a groove is provided on the end surface of the pressing step, and a rubber pad is provided in the groove.

[0010] Furthermore, a positioning hole is provided in the engaging groove, and a positioning column matched with the positioning hole is provided on the pressing block.

[0011] The invention also provides a method for using a rotating adaptive wire top-binding fixture, which comprises the following steps: S1: Install the buckle ring. Connect the buckle ring and the wire pressing plate as a whole through the fixing bolts. Then align the concave surface of the buckle ring with the two ends of the wire groove of the porcelain bottle skirt cover, so that the opening direction of the buckle ring corresponds to the edge of the porcelain bottle skirt cover. Then, gently buckle the buckle ring onto the porcelain bottle skirt cover, and then rotate the buckle ring so that the buckle groove formed between the lower pressure step and the upper pressure step buckles onto the porcelain bottle skirt cover. S2: Wire placement. After the buckle is installed, place the wire to be fixed on the guide groove of the porcelain bottle skirt cover to ensure that the wire is in the appropriate position and does not deviate or fall out. S3: Fix the connection. Finally, tighten the tightening bolts to fix the wire pressing plate and the buckle ring. When tightening the fixing bolts, pay attention to even force so that the wire pressing plate gradually presses the wire until the wire is firmly fixed between the buckle ring and the wire pressing plate, completing the fixing of the wire.

[0012] The beneficial effects of the present invention are: 1. Simplified structure and fewer parts: This fixture is mainly composed of a buckle, a wire pressing plate and two fixing bolts. Compared with the complex structure of the traditional wire fixing clamp, which includes a left clamp body, a right clamp body and two pairs of arc-shaped clamps, the overall structural design is greatly simplified. The reduction in the number of parts not only reduces the cost and difficulty of production, but also makes the storage, transportation and management of the product more convenient and efficient, reducing the problems of loss and mismatch caused by the large number of parts.

[0013] 2. Convenient disassembly and assembly: This fixture is very convenient during the disassembly and assembly of the conductor. When using it, you only need to simply buckle the buckle on the porcelain bottle skirt cover and rotate it to fix it, then place the conductor and connect the buckle with the wire pressing plate through the fixing bolt to complete the conductor fixation; when the conductor needs to be removed, just loosen the fixing bolt and rotate the buckle in the opposite direction to easily remove it, without the need to tediously remove multiple bolts and disassemble the left and right clamps separately like traditional fixing clamps. This convenient disassembly and assembly method greatly shortens the operation time during the construction, maintenance and overhaul of power lines, improves work efficiency, reduces the impact of power outages on the stability of power supply, and also reduces the labor intensity of operators.

[0014] 3. Good fixing stability: The buckle tightly engages with the skirt cover of the porcelain insulator through its uniquely designed downward pressing step and upward pressing step, which can effectively prevent the fixator from displacing or loosening on the porcelain insulator. The wire pressing plate applies a stable pressure to the wire under the action of the fixing bolt, ensuring that the wire maintains a fixed position in the guiding groove at the top of the porcelain insulator. Even under harsh natural environments such as strong winds and vibrations, the connection stability between the wire and the porcelain insulator can be reliably maintained, thereby ensuring the safe and reliable power transmission, effectively reducing the risk of line faults caused by unstable wire fixing, and improving the reliability and safety of the power system operation.

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, in the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "No. 1", "No. 2" and "No. 3" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. The present invention is further explained below in conjunction with specific embodiments.

[0024] The invention provides a rotary adaptive wire top-binding fixer.

[0025] In this embodiment, refer to Figures 1-7 The rotating adaptive wire top-binding fixture comprises: A buckle ring 1, the buckle ring 1 as a whole is an annular structure adapted to the skirt cover 3 on the top of the porcelain bottle 2, the middle part of the buckle ring has a recessed recessed surface 4, the bottom of the buckle ring located on both sides of the recessed surface 4 has a downwardly extending downward pressure step 5, the upper end surface of the buckle ring has an upward pressure step 6 extending inward, and a buckle groove 7 for buckling on the skirt cover of the porcelain bottle is formed between the downward pressure step and the upward pressure step; The wire pressing plate 8 is located above the buckle ring and is connected to the buckle ring through a fixing bolt 9.

[0026] In the above technical solution, the annular structure of the buckle is adapted to the skirt cover on the top of the porcelain bottle. When in use, the buckle is inserted into the skirt cover on the top of the porcelain bottle, which ensures the integrity and stability of the connection between the fixer and the porcelain bottle, and can effectively fit the porcelain bottle to prevent loosening or displacement under various working conditions.

[0027] The concave surface in the middle leaves space for the wire groove on the porcelain bottle to avoid interference with the normal laying of the wire. At the same time, the buckling groove formed by the downward pressure steps on both sides and the upward pressure steps on the upper end allows the buckle to be firmly buckled on the porcelain bottle skirt cover, ensuring the installation stability of the fixture on the porcelain bottle, bearing the tension of the wire and the influence of external environmental factors, and ensuring the safe and reliable operation of the power transmission line.

[0028] The wire pressing plate is connected to the buckle through fixing bolts, forming a clamping and pressing structure for the wire, which can effectively fix the wire to prevent it from shaking or shifting, ensure the tightness of the connection between the wire and the porcelain bottle, and reduce the energy loss and fault risk caused by poor contact.

[0029] Specifically, fixing screw holes 10 are provided at both ends of the buckle, and fixing holes 11 corresponding to the fixing screw holes 10 are provided at both ends of the wire pressing plate.

[0030] In this embodiment, the fixing screw holes at both ends of the buckle correspond to the fixing holes at both ends of the wire pressing plate, enabling precise positioning during the connection of the fixing bolts, facilitating the installation operation, and improving the assembly efficiency.

[0031] Specifically, a fitting groove 12 is provided at the bottom of the wire pressing plate, a pressing block 13 is fitted in the fitting groove 12, and an arc-shaped pressing surface 14 is provided at the bottom of the pressing block 13.

[0032] In this embodiment, the pressing block is fitted in the fitting groove at the bottom of the wire pressing plate, and the arc-shaped pressing surface at the bottom of the pressing block can better conform to the shape of the wire, increasing the contact area with the wire and making the pressure distribution more uniform. When fixing the wire, it can effectively prevent damage to the wire insulation layer or deformation of the wire due to excessive local pressure, improving the safety and stability of wire fixing. At the same time, it is also beneficial to maintain the good performance of the wire during long-term use, extend the service life of the wire, and ensure the stable operation of the power system.

[0033] Among them, the fitting pressing block and the fitting groove can be bonded with glue to improve their connection stability.

[0034] Specifically, an arc surface 15 or an inclined surface 16 inclined towards both sides of the wire pressing plate is provided at the top of the wire pressing plate.

[0035] In this embodiment, an arc surface or an inclined surface inclined towards both sides is provided at the top of the wire pressing plate. In the actual use environment, when encountering natural factors such as rain and dust, this design can reduce the accumulation of impurities on the top of the wire pressing plate, avoid problems such as corrosion and short circuit caused by water accumulation or dust accumulation, reduce the possibility of negative impacts on the performance of the fixer due to environmental factors, improve the environmental adaptability and durability of the fixer, reduce the maintenance cost and maintenance frequency, and ensure the continuous and stable operation of the power line.

[0036] Specifically, a groove 17 is provided on the end face of the lower pressing step, and a rubber pad 18 is arranged in the groove 17.

[0037] In this embodiment, the rubber pad provided on the end face of the lower pressing step has multiple functions. On the one hand, the rubber pad can increase the friction between the lower pressing step and the skirt cover of the porcelain insulator, further improving the fixing stability of the buckle on the porcelain insulator and preventing the buckle from loosening due to external force factors such as vibration and wind. On the other hand, the rubber material has a certain buffering effect, which can absorb external impact forces to a certain extent, protect the surface of the skirt cover of the porcelain insulator from being scratched or worn, and at the same time reduce the noise generated by rigid contact, improving the reliability and use comfort of the entire wire fixer and porcelain insulator combined structure, and being beneficial to the long-term stable operation and maintenance of power facilities.

[0038] Specifically, a positioning hole 21 is provided in the embedding groove, and a positioning column 22 matched with the positioning hole is provided on the pressing block.

[0039] In this embodiment, a positioning hole is provided in the fitting groove and a positioning column is provided on the pressing block to match the positioning hole, so that the pressing block can be accurately positioned when it is inserted into the fitting groove. This ensures the position accuracy and consistency of the pressing block each time it is installed, so that the arc-shaped pressing surface at the bottom of the pressing block can stably and evenly contact the wire, effectively avoiding the situation where the wire is unevenly stressed due to the position deviation of the pressing block.

[0040] The invention also provides a method for using a rotating adaptive wire top-binding fixture, which comprises the following steps: S1: Install the buckle ring. Connect the buckle ring and the wire pressing plate as a whole through the fixing bolts. Then align the recessed surface of the buckle ring with the two ends of the wire groove 19 of the porcelain bottle skirt cover, so that the opening direction of the buckle ring corresponds to the edge of the porcelain bottle skirt cover. Then, gently buckle the buckle ring onto the porcelain bottle skirt cover, and then rotate the buckle ring so that the buckle groove formed between the lower pressing step and the upper pressing step buckles onto the porcelain bottle skirt cover.

[0041] S2: Wire placement. After the buckle is installed, place the wire 20 to be fixed on the guide groove of the porcelain bottle skirt cover to ensure that the wire is in a suitable position and does not deviate or fall out.

[0042] S3 fixed connection, finally, tighten the fixing bolts to press the wire pressing plate and buckle to fix them. When tightening the fixing bolts, pay attention to even force, so that the wire pressing plate gradually presses the wire until the wire is firmly fixed between the buckle and the wire pressing plate, completing the fixing of the wire.

[0043] Among them, in the buckle ring installation step, the buckle ring and the wire pressing plate can be connected as a whole through the fixing bolts, that is, during disassembly and assembly, the wire holder can be a whole, and the whole can be removed and installed by just loosening the fixing bolts. There is no need for the assemblers to carry multiple parts for installation work, which greatly improves the convenience of disassembly and assembly.

[0044] This method of use allows the wire holder to be handled as a whole during assembly and disassembly. The entire holder can be easily removed from or installed on the porcelain bottle by simply loosening the fixing bolts, without the need for the assembler to carry and handle multiple parts separately, such as separate buckles, wire pressing plates, etc., as in the traditional method. This greatly reduces the risk of parts being lost or misplaced during installation and disassembly, significantly improving work efficiency, especially in high-altitude operations or limited working space, which can better demonstrate its advantages and greatly reduce the labor intensity and difficulty of the operator.

[0045] In addition, since the buckle and the wire pressing plate are pre-connected as a whole for the buckle installation step, the positioning and adjustment time between components during traditional step-by-step installation is reduced. The entire installation process is simple and clear, and the connection between steps is tight. Operators can complete the wire fixing work more quickly, thereby shortening the construction or maintenance time of the power line, reducing the impact of power outage time on the continuity of power supply, improving the reliability and stability of the operation of the power system, and being conducive to the efficient operation and maintenance management of the power industry.

[0046] Finally, whether it is in the construction of a new power line project or the renovation and upgrade of an existing line, this integrated disassembly and assembly method can show good adaptability. Its simple and reliable operation process reduces the requirements for the skill level of operators, enabling more workers to master it proficiently, and it can function stably in various complex working environments and conditions. It effectively guarantees the firmness and stability of the connection between the wire and the insulator, reduces the risk of line failures caused by improper installation of the fixator, and improves the safety and quality of power transmission.
