Technical Field

[0001] The present invention belongs to the technical field of electric power equipment, and in particular relates to a transmission line tension regulating device and a use method thereof. Background Art

[0002] When the overhead transmission line is erected, it is generally required to ensure that the insulator string on the straight pole tower is plumb and the unbalanced tension of the conductors on both sides of the straight pole tower suspension clamp is zero. However, when the meteorological conditions change, due to the differences in the spacing, height difference, load, etc. of the grid in the tension section, the conductors on both sides of the straight pole tower suspension clamp will usually have unbalanced tension, especially when uneven ice coverage and uneven ice shedding occur in the grid, the effect of unbalanced tension will be more obvious. When the unbalanced tension reaches a certain limit value, it will cause the transmission line to break or even the pole tower to overturn. Overhead lines generally use wire clamps to erect transmission lines, but the wire clamps of the card plate structure are fixedly connected to the transmission line, and there is no There is no way to adjust the tension on the transmission line. However, due to the influence of various factors such as meteorological conditions, the transmission lines at both ends of the wire clamp often produce unbalanced tension during the operation of the line. In fact, the direction of the unbalanced force for the structure such as the wire clamp is uncertain. It is an irregular directional force. Therefore, only changing the two ends of the wire clamp cannot effectively eliminate the unbalanced tension of the transmission line, resulting in poor actual effect. It will still endanger the safety of the line and tower, and bring major safety hazards to the normal operation of the transmission line. Therefore, it is very necessary to provide a transmission line tension adjustment device and a method of use that has a reasonable structure, multi-directional self-adjustment, good flexibility, safety and reliability.

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a transmission line tension adjustment device and a method of use which have a reasonable structure, multi-directional self-adjustment, good flexibility, and are safe and reliable.

[0004] The objective of the present invention is achieved as follows: a transmission line tension adjustment device comprises an installation adjustment mechanism and a balance ring, a damping slider is freely slidably installed on the installation adjustment mechanism, an insulator is arranged below the damping slider, the upper end of the insulator is connected to the damping slider through the balance ring, a fixed wire clamp is arranged below the insulator, the lower end of the insulator is connected to the fixed wire clamp through a multi-directional balance control mechanism, and a conductor is installed in the fixed wire clamp.

[0005] The installation and adjustment mechanism includes a slide rod, the damping slider contacts the outer surface of the slide rod, both ends of the slide rod are fixedly connected with guide blocks, the upper end of the guide block is slidably installed with an adjustment light rod, and both ends of the adjustment light rod are fixedly installed with mounting seats.

[0006] The balancing ring includes an annular main frame and a balancing plate. The end surfaces on both sides of the upper opening of the annular main frame are movably mounted with shaft plates. The shaft plates are connected by a shaft rod. Both ends of the shaft rod are fixedly connected to the shaft plates by fixing clamps. A mounting plate connected to the lower end surface of the damping slider is arranged outside the shaft rod. The mounting plate is fixedly connected to the shaft rod by a group of positioning clamps.

[0007] The annular main frame is an annular structure with an opening at the top, the balance plate is located at the bottom of the annular main frame, and both sides of the upper part of the balance plate are movably connected to the annular main frame through a group of limiting rollers, and a group of limiting rollers are respectively located on the inner circumferential surface and the outer circumferential surface of the annular main frame.

[0008] The multi-directional balance control mechanism comprises a bracket, which is fixedly connected to the lower end of the insulator through a balance connector; the bracket is a "cross" structure composed of four "L"-shaped support plates arranged in a central symmetrical manner.

[0009] A balance bar with an acute "L"-shaped structure is arranged below the bracket, a balance shaft plate is arranged on the upper end of the balance bar, and the balance shaft plate is connected to the bracket through a universal ball shaft seat, a clamping block is arranged at the lower end of the balance bar, and a mounting base for connecting and fixing the wire clamp is arranged on the inner side of the clamping block.

[0010] The balancing connector includes a connecting ring, a mounting hole is arranged inside the connecting ring, a plurality of waist-shaped holes are evenly arranged on the periphery of the mounting hole, a U-shaped clip is installed inside the waist-shaped hole, a rope end connected to the U-shaped clip by a hexagon socket bolt is arranged inside the U-shaped clip, and a balancing rope connected to the bracket is installed on the rope end.

[0011] A method for using a transmission line tension adjustment device, using the transmission line tension adjustment device as described above, to automatically adjust the unbalanced tension of a transmission line conductor, comprising the following steps: Step 1: Connect the upper end of the insulator to the damping slider through a balance ring, and then connect the lower end of the insulator to the fixed wire clamp through a multi-directional balance control mechanism; Step 2: When a small unbalanced tension is generated in the transmission line, the conductor first acts on the balance rod of the multi-directional balance mechanism, causing the lower end of the insulator to deflect, preliminarily eliminating the small unbalanced force; Step 3: When a small unbalanced tension is generated in the transmission line, after a part of the unbalanced force is initially eliminated in the previous step, the upper end of the insulator drives the balance ring to swing, causing the upper end of the insulator to deviate, and the remaining unbalanced force is eliminated again; Step 4: When a large unbalanced tension is generated in the transmission line, after a part of the unbalanced force is initially eliminated in the above two steps, the balancing ring drives the damping slider to move on the slide rod. Since the force is multi-directional, the guide block can also be driven to move on the adjusting light rod to cause the insulator to shift as a whole, thereby releasing the unbalanced tension by changing the distance between the lines. After the action of the multi-stage balancing components, the remaining unbalanced force is completely eliminated, and the unbalanced tension of the conductor is automatically adjusted, thereby ensuring the safe operation of the transmission line.
