Problems solved by technology

For both tightening tools, there are disadvantages to each
The hydraulic tensioner has a large pulling tonnage, but there are also problems such as large volume and heavy weight that make it difficult to display in the effective space, and the force on the hydraulic side leads to insufficient bending resistance of the line fixture; while the screw tensioner is easy to operate, but There is also the problem of limited pulling tonnage

Abstract

The invention discloses a wire tightening tool for a power transmission line lead and a wire tightening method. One end of a hand-operated screw rod is connected to a connector of a pulling plate; the other end of the hand-operated screw rod is connected to one end of a guide rod (3); the other end of the guide rod (3) is connected to a piston rod of an oil cylinder (2); the cylinder body of the oil cylinder (2) is connected to a connector of a clamping tool (1); the connector of the pulling plate is connected to the pulling plate; the clamping tool connector is connected to the clamping tool; and, firstly, the hand-operated screw rod is utilized to realize the front load transferring of long distance and small pulling force, and secondly, the oil cylinder is utilized to realize the rear load transferring of the short distance and big pulling force. The invention discloses a wire tightening device for the power transmission line, which is applicable to the replacement operation of glass insulators or ceramic insulator, short in the effective stroke, light in weight, easy in operation and high in operation efficiency.

Description

technical field [0001] The invention relates to a wire tightening tool, in particular to a wire tightening tool suitable for the replacement of glass and porcelain insulators. The invention also relates to the use method of the power transmission line wire tightening tool. Background technique [0002] Existing wire tensioning tools mainly include hydraulic wire tensioner and screw rod wire tensioner. With both tightening tools, there are drawbacks to each. The hydraulic tensioner has a large pulling tonnage, but there are also problems such as large volume and heavy weight that make it difficult to display in the effective space, and the force on the hydraulic side leads to insufficient bending resistance of the line fixture; while the screw tensioner is easy to operate, but There is also the problem of limited pulling tonnage. [0003] According to the structural analysis of the insulator and the way of hanging the wire, when replacing the insulator, the composite insul...
