Abstract
Description
Technical Field
[0001] The invention relates to the field of electrical fixing fixtures for transformer substations, and in particular to a multifunctional adjustable fixture for repairing a non-stop switch mechanism. Background Art
[0002] Clamps are an important technical measure used for fixing in the power industry. During equipment maintenance, in order to prevent maintenance personnel from malfunctioning the electrical equipment due to misoperation of the mechanism, maintenance clamps are usually used to fix and lock the mechanism to ensure the safety of the maintenance equipment.
[0003] Because the maintenance of knife switches is often carried out without power outages, in order to prevent the knife switches from being opened or closed incorrectly due to misoperation by the maintenance personnel during the maintenance without power outages, it brings certain troubles to the maintenance personnel during the maintenance without power outages.
[0004] Publication No. CN106025886A discloses a vertical connecting rod fixator for live inspection of a knife switch mechanism. This device secures the knife switch mechanism using an arc-shaped clamp and horizontal connecting rods, enabling live inspection of the knife switch mechanism. However, the clamps can sometimes become loose during operation, limiting its applicability and lacking flexibility, making it inflexible and unable to accommodate connecting rods and support columns of varying sizes.
[0005] Publication No. CN206819923U discloses a device for replacing a knife switch operating mechanism. This device uses a handle, clamp, horizontal channel steel, and other limiting components to rotate a vertical connecting rod around its original axis to achieve the opening and closing functions. This allows the knife switch operating mechanism to be replaced without power outages. However, the handle rotation adjustment of this device is complex and prone to malfunctions. Furthermore, the distance between the knife switch operating rod and support rod is difficult to adjust, making it difficult to accurately position the knife switch operating mechanism. Summary of the Invention
[0006] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a multifunctional adjustable clamp for the maintenance of knife switch mechanism without power outages, so as to prevent the knife switch from malfunctioning during the maintenance of the knife switch mechanism without power outages, solve the problem of non-power outage operation during the maintenance of the knife switch mechanism, and at the same time avoid the power supply reliability caused by power outages and improve the economic benefits of the power grid.
[0007] To this end, the present invention proposes a multifunctional adjustable clamp for repairing a knife switch mechanism without power outages, including a knife switch base rod clamp, a knife switch mechanism vertical connecting rod clamp, an adjustable telescopic rod, a telescopic rod sleeve, and a multifunctional clamp body. Two multifunctional clamp bodies are provided, and each multifunctional clamp body is provided with at least three mounting holes. The knife switch base rod clamp cooperates with the mounting holes on one multifunctional clamp body to clamp the knife switch base rod, and the knife switch mechanism vertical connecting rod clamp cooperates with the mounting holes on another multifunctional clamp body to clamp the knife switch mechanism vertical connecting rod.
[0008] At least one telescopic rod sleeve is provided on each of the multifunctional clamp bodies, and one adjustable telescopic rod is installed in the telescopic rod sleeve; the multifunctional clamp body where the knife gate base rod clamp is located and the multifunctional clamp body where the knife gate mechanism vertical connecting rod clamp is located are connected together through the adjustable telescopic rod, and the adjustable telescopic rod slides inside the telescopic rod sleeve to facilitate adjustment of the distance between the knife gate base rod and the knife gate mechanism vertical connecting rod.
[0009] Furthermore, the spacing between at least two of the mounting holes in the multifunctional clamp body matches the size of the knife gate base rod clamp, and the spacing between two more mounting holes matches the size of the knife gate mechanism vertical connecting rod clamp.
[0010] Furthermore, the multifunctional clamp body is provided with four mounting holes, and the four mounting holes are symmetrically distributed about the central symmetry plane of the multifunctional clamp body.
[0011] Furthermore, the telescopic rod sleeve is provided with a threaded hole, and the threaded hole is provided with a telescopic rod positioning screw for fixing the adjustable telescopic rod.
[0012] Furthermore, two adjustable telescopic rods are provided, and two telescopic rod sleeves are provided on each multifunctional clamp body.
[0013] Furthermore, the two telescopic rod sleeves on the same multifunctional clamp body are parallel to each other and arranged horizontally.
[0014] Furthermore, the multifunctional clamp is specifically designed to have different types of clamp openings, which are suitable for multiple types of structural knife switches of 110kV and 220kV voltage levels.
[0015] Furthermore, a mechanism box is connected to the vertical connecting rod of the knife switch mechanism.
[0016] The multifunctional adjustable clamp for inspecting the knife switch mechanism without power outages provided by the present invention utilizes the ingenious structure of the adjustable clamp to fix the device to the knife switch vertical connecting rod and the knife switch base rod, and utilizes the telescopic rod to adjust the distance, so that maintenance personnel can carry out maintenance work without power outages on the knife switch.
