Embodiment Construction

[0029] see Figure 1 ~ Figure 1 0, the connecting plate tensioner 8 for overhead line tightening includes a V-shaped body 801, and the V-shaped body 801 includes two legs, each of which is provided with a hook 802; the legs include a first leg 8011 and a second leg 8012, the first leg 8011 is provided with a fixing plate 803, and the fixing plate 803 is provided with a The thickness direction passes through the fifth through hole 8031 ​​of the fixing plate 803 .

[0030] The two supporting legs of the connecting plate tensioner are made of a steel bar, the steel bar is bent in a V shape, and the bending part is arc-shaped. There is a hook on each leg. During the wire tightening operation, the connecting board wire tightening device is used to connect the double-string porcelain bottles. A connecting plate 1201 is arranged between the two strings of porcelain bottles 12 of the double-stringing porcelain bottles. The connecting plate 1201 is provided with a plurality of throug...

Abstract

The invention discloses a yoke plate tightener for overhead line stringing. The yoke plate tightener comprises a V-shaped body, wherein the V-shaped body comprises two landing legs, and each landing leg is provided with a hook; the two landing legs comprise the first landing leg and the second landing leg, wherein the first landing leg is provided with a fixed plate, and the fixed plate is provided with a fifth through hole which penetrates through the fixed plate in the thickness direction of the fixed plate; the joint of the two landing legs of the V-shaped body is of an arc shape. The yoke plate tightener for overhead line stringing has the advantages of enabling a hauling cable and double-string porcelain insulators to be reliably connected, being capable of improving safety and reliability of electric transmission line conductor stringing, improving stringing efficiency and lowering labor intensity of workers on towers, reducing the number of the workers, being low in construction difficulty and the like.

Description

technical field [0001] The invention relates to a plate-connecting wire tensioner used for wire tightening of overhead lines, in particular to a board-connecting wire tensioner used for wire tightening of overhead line conductors in a power system. Background technique [0002] At present, the main method of tightening the wires of transmission lines is to fix the traction rope on the tension clamp. After the wire is tightened, due to gravity, the porcelain bottle is strung under the line, and it needs manpower to twist the porcelain bottle up to the level of the wire and then install it on the cross arm of the pole tower. Guarantee, low line efficiency and high construction cost. [0003] When the double-string insulator string conductors of the transmission line are tightened, a steel wire rope is generally used to tie the insulators and conductors on two pulleys to lift the insulators and conductors. Screw it up to the level of the wire and install it on the cross-arm o...
