Linear tackle for adjusting sag of vertical double-split conductor

Abstract

The invention relates to a linear tackle for adjusting the sag of a vertical double-split conductor. The linear tackle disclosed by the invention is characterized by comprising a bearing suspension plate, a fixed bearing suspension plate, a movable bearing suspension plate and a pulley, wherein the fixed bearing suspension plate is arranged at one side of the bearing suspension plate; the movable bearing suspension plate is arranged at the other side of the bearing suspension plate and parallel to the fixed bearing suspension plate; the pulley is fixed between the fixed bearing suspension plate and the movable bearing suspension plate through a bearing; the movable bearing suspension plate is connected with the bearing suspension plate through a hinge; and a locking pin is arranged at one end of the bearing near the movable bearing suspension plate. A horizontal double-wheel tackle is adopted in the linear tackle; therefore, the bearing point and the wheel diameter for the conductor to pass through the tackle are increased; pressure of the conductor on each pulley when the sag is adjusted is greatly reduced; damage to the conductor is lightened; all the parts of the linear tackle are made of high-strength materials; therefore, the overall weight of the special linear tackle is reduced; and the linear tackle is convenient and flexible to assemble or disassemble.

Description

technical field [0001] The invention belongs to the electric power industry and is suitable for adjusting the sag of a vertical double-split conductor of a straight line tower of a high-voltage transmission line, and in particular relates to a linear block used for adjusting the sag of a vertical double-split conductor. Background technique [0002] At present, in the power industry, during the long-term operation of the vertical double-split conductors of high-voltage transmission lines, due to various reasons, the conductor sag will appear abnormal, resulting in the distance between the two sub-conductors being too small, and the occurrence of conductor whipping or adhesion, which is extremely serious. It is easy to cause wire breakage and wire breakage. At present, there is no special pulley in China that can effectively adjust the sag of vertical double-split conductors, and the main method is to manually dispose of the conductors. During the disposal process, the safety...

Problems solved by technology

[0002] At present, in the power industry, during the long-term operation of the vertical double-split conductors of high-voltage transmission lines, due to various reasons, the conductor sag will appear abnormal, resulting in the distance between the two sub-conductors being too small, and the occurrence of conductor whipping or adhesion, which is extremely serious. Prone to wire breakage and wire breakage

At present, there is no special pulley to effectively adjust the sag of vertical double-split conductors in China, and the conductors are mainly disposed of manually. During the disposal process, the safety risk of personnel leaving the conductors is relatively large and it is labor-intensive.
