Description

Technical Field

[0001] The present application relates to the technical field of wire tensioners, and in particular to a porcelain column wire tensioner. Background Art

[0002] As a necessary connector in the installation of high (low) voltage overhead lines, the tensioner plays an indispensable role in fixing the power supply cables. Its convenience, reliability and durability greatly reduce the difficulty of laying cables, providing strong support for the process of urbanization development.

[0003] In the prior art, when a porcelain column tensioner is used to fix the wire, it is composed of an upper and lower pressure plate and two stainless steel bolts. The two arc-shaped lower pressure plates can be adjusted and locked according to the size of the insulator. The locking bolts fix the pressure plate, the wire, and the lower pressure plate to the insulator, and an insulating protective cover is provided at the very end to prevent the metal from being exposed and to prevent unnecessary electric shock hazards. Then, because the working environment of the tensioner is often set at a higher altitude environment, it is inconvenient for the installer to operate during the operation. Therefore, when installing or removing the protective cover that is completely separated from the tensioner, it is easy for the protective cover to have nowhere to be placed, resulting in the risk of falling from a high altitude. Even if the above-mentioned accident does not occur, the protective cover needs to be stored in an additional place or held with one hand, which is neither stable nor safe. Therefore, there is room for improvement. Summary of the Invention

[0004] In response to the above problems, the present application proposes a porcelain column tensioner, which is provided with a connecting device between the upper pressing plate and the protective cover to connect the upper pressing plate and the protective cover. The connecting device does not affect the disassembly and installation of the protective cover, but can prevent the protective cover from falling from a high altitude, thereby achieving the beneficial effects of safety and facilitating installation. The porcelain column tensioner is specifically implemented through the following technical solutions:

[0005] A porcelain column tensioner includes: an upper pressure plate and a lower pressure plate, the upper pressure plate and the lower pressure plate are pressed against each other by setting a locking bolt, the upper pressure plate is also provided with a protective cover, and the protective cover is provided with an installation component so that the protective cover can be detachably arranged on the upper pressure plate, and a connecting device is provided between the upper pressure plate and the protective cover, and the connecting device maintains the connection between the upper pressure plate and the protective cover in both the disassembled state and the installed state realized by the installation component between the protective cover and the upper pressure plate.

[0006] It is further provided that the connecting device includes a connecting ring, a connecting rope, a connecting hole and a limit block, the connecting ring is provided on a side of the upper pressure plate on which the protective cover is installed, the connecting hole is provided at a projection position of the protective cover corresponding to the connecting ring, one end of the connecting rope passes through the connecting ring and is fixed in the form of a knot, and the other end of the connecting rope passes through the connecting hole and is connected to the limit block. Through this provision, the upper pressure plate and the protective cover are connected by the connecting rope, and even if the mounting assembly is disassembled, they will not be completely detached, thereby realizing basic functions.

[0007] It is further provided that the connecting ring and the upper pressure plate are provided as an integrated structure. Through this provision, the overall strength of the connecting ring is improved, making the overall structure stable.

[0008] It is further provided that the protective cover is provided with an active cavity corresponding to the locking active direction of the locking bolt. Through this provision, the protective cover will not interfere with the locking bolt, and the overall structure is tighter and more stable.

[0009] It is further configured that the mounting assembly includes a clamping ring arranged on the outer peripheral edge of the protective cover, and a clamping block arranged on the outer peripheral edge of the upper pressure plate corresponding to the clamping ring. The upper pressure plate and the protective cover realize the disassembly state and the installation state through the clamping and separation of the clamping ring and the clamping block. Through this configuration, the basic function of the protective cover is conveniently realized, and it is installed on the upper pressure plate to hide the metal surface and prevent the occurrence of electric shock hazards.

[0010] It is further configured that the lower pressure plate includes a first arc plate and a second arc plate, the inner ends of the first arc plate and the second arc plate are rotatably connected to form an annular locking ring capable of adjusting the diameter, and the outer ends of the first arc plate and the second arc plate are connected by the locking bolt pin. Through this configuration, the connection size between the lower pressure plate and the connecting part (porcelain column) is adjustable, which can adapt to porcelain columns of different sizes, thereby improving the scope of application.

[0011] It is further provided that the outer end of the first arc plate is provided with a plurality of positioning holes in a circumferential array with the annular locking ring as the center. Through this setting, the size of the annular locking ring is locked, and the overall structure is more stable.

[0012] It is further provided that a locking hole is provided at the outer end of the second arc plate corresponding to the position of the positioning hole, and the locking bolt is locked in the locking hole after passing through the positioning hole. Through this setting, the size of the annular locking ring is locked, and the overall structure is more stable.

[0013] In summary, the porcelain column tensioner is provided with a connecting device between the upper pressure plate and the protective cover to connect the upper pressure plate and the protective cover, and the connecting device does not affect the disassembly and installation of the protective cover, but can prevent the protective cover from falling from a high altitude, which has the beneficial effects of safety and convenient installation.
