A conductive rod assembly tooling

Abstract

The invention discloses a conducting rod assembly fixture which comprises three supporting frames evenly distributed on one circle, wherein every two adjacent supporting frames are detachably connected to form an annular framework, the end, located outside the annular framework, of each supporting frame is provided with an idler wheel used for being in contact with the inner wall of a pipe to be installed, the end, located inside the annular framework, of each supporting frame is provided with a support plate used for being in contact with a conducting rod at the center of the pipe to be installed and positioning the conducting rod, and every two adjacent supporting frames are detachably connected in a distance adjustable mode through spiral adjusting mechanisms. The assembly fixture is simple in structure, detachable and convenient to carry. Meanwhile, due to the fact that the distance between every two supporting frames is adjustable, the assembly fixture is applicable to assembly of conducting rods of pipes in different diameters to be installed.

Description

technical field [0001] The invention relates to the field of assembly of high-voltage, ultra-high-voltage, and ultra-high-voltage pipeline busbars, in particular to a process device for installing inlet and outlet bushings and conducting rods in pipeline busbars. Background technique [0002] At present, as the voltage level of high-voltage electrical equipment increases, the creepage distance and insulation distance of the incoming and outgoing porcelain bushings (composite bushings) also increase, and the diameter and length of the corresponding porcelain bushings also increase. The diameter of the million-volt incoming and outgoing porcelain bushing is more than one meter, and the length is more than ten meters long. When the conductive rod is installed in the porcelain casing of this length, there is a phenomenon that the conductive rod "bows its head", and there are two general solutions: one method is to directly add a sheath made of flexible material to the end of the...

Problems solved by technology

When the conductive rod is installed in the porcelain casing of this length, there is a phenomenon that the conductive rod "bows its head", and there are two general solutions: one method is to directly add a sheath made of flexible material to the end of the conductive rod , use the sheath to contact the inner wall of the casing. Although the structure of the sheath is simple in this method, there is a large friction between the sheath and the porcelain casing. When the sheath moves with the conductive rod, the end of the conductive rod The part is often exposed from the sheath, so that the protection of the sheath to the conductive rod is not in place, so that the end of the conductive rod will directly contact the inner wall of the porcelain sleeve, and eventually cause the inner wall of the porcelain sleeve to be scratched; another method It is to use a small pulley to support the conductive rod inside the casing to prevent the end of the conductive rod from colliding with the inner wall of the casing. Although this method is simple, the small pulley can only prevent the end of the conductive rod from colliding with the porcelain when in use. The inner wall of the casing cannot help the centering and positioning of the conductive rod, and other means are needed to assist centering and positioning in subsequent use, which increases the labor intensity of the conductive rod assembly

[0003] The Chinese utility model patent with the notification number CN202363840U discloses a guide car for GIS three-phase common box busbar conductive rod tooling. Through the coaxial connection of the connecting rod extending front and back, a conductor hole for the conductive rod to be installed is opened on the guide body and the positioning plate, and several small rollers are evenly distributed on the hole wall of the conductor hole. There are several large rollers on the outer periphery of the body, through which the guide body coaxially slides into the busbar tube to ensure that the conductor holes on the guide body and the positioning plate are opposite to the contact seats on the disc insulator on the busbar tube, but as the busbar As the diameter of the pipe continues to increase, the size of the positioning plate and the guide body required also become larger and larger, which makes the entire tooling heavy and increases the labor and operation difficulty of installing the conductive rod in the busbar pipe, reducing the Work efficiency, but also very inconvenient to carry

In addition, the diameter of the disc-shaped guide body and the positioning plate of this guide car is fixed, so it can only be used for a busbar with one diameter. usage cost
