Description

A conductive rod assembly device

technical field

The utility model 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 incoming and outgoing line sleeves and conducting rods in pipeline busbars.

Background technique

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 even 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 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 sleeve can not 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.

The Chinese utility model patent with the notification number CN202363840U discloses a guiding vehicle for a GIS three-phase common box busbar conductive rod device. 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 whole device bulky, increases the labor and operation difficulty of installing the conductive rod in the busbar pipe, and reduces the Work efficiency, also very inconvenient when carrying. 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. use cost.

A detachable connection with adjustable distance is realized between two adjacent support frames through a screw adjustment mechanism.

The screw adjustment mechanism includes an end threaded connector hinged on two adjacent support frames and a positive and negative double-ended threaded connector whose two ends are correspondingly threaded to connect the end connectors on two adjacent support frames.

The rollers installed on the support frame are single-row rollers or double-row rollers extending along the axis of the conductive rod, and at least one row of rollers has more than two rows.

The rollers installed on at least one of the three support frames are universal wheels.

At least one of the three supporting plates is provided with a mounting groove on the side contacting with the conductive rod, and a wedge for wedging the conductive rod is installed in the mounting groove.

The wedge is provided with a connecting structure for fastening a rope.

The positioning of the three points of the degree realizes the centering and positioning of the conductive rod. At the same time, the adjacent two of the three support frames are detachably connected, so that when workers need to go to the outdoor site to repair the busbar or When sleeved, the device can be disassembled for easy portability.

Further, the engaging teeth on one of the supporting plates and the engaging grooves on the other supporting plate are engaged with each other between two adjacent supporting plates, which prevents the conductive rod from being dislodged from the two due to the self-weight of the conducting rod during the assembly process of the conducting rod. Slipping between the pallets will injure the installed pipe or human hands.

Further, there is a detachable connection with adjustable distance between two adjacent support frames, so that when the diameters of the installed pipes are different, the outer ends of the three support frames can be adjusted by adjusting the distance between the two adjacent support frames. The diameter of the circumference where the connected rollers are located becomes larger or smaller to adapt to the diameter of the pipe to be installed, and there is no need to make another set of devices, which greatly reduces the cost.

Furthermore, the adjustable connection between the three support frames is realized through a screw adjustment mechanism, so that when the distance between two adjacent support frames is adjusted to adapt to the diameter of the pipe to be installed, the adjustment amount can be precisely controlled, which improves the accuracy of the control. The positioning accuracy of the conductive rod improves the assembly efficiency.
