Embodiment Construction

[0038] The wire passing pulley detection device provided by the present invention mainly includes: a positive triangle detection device and an inverted triangle detection device. Among them, the positive triangle over pulley detection system and the inverted triangle over pulley detection system can complete the pulley detection independently, and can also be carried out by both systems at the same time as required.

[0039] Such as figure 1 Shown: The positive triangle detection device is connected by a pulley, a frame tower, and a driving pulley system.

[0040] The pulley includes a pulley frame, a mobile frame and a pulley support frame. The moving frame moves in the axial direction where the detection device is located. The trolley frame is a cuboid parallel to the axial direction, and the side is provided with a chute; the main body of the mobile frame is a flat structure parallel to the axial direction, and its two sides are provided with bends perpendicular to the fl...

Abstract

The invention provides a wire detection method. The wire detection method is characterized in that the detection method includes a triangle wire detection method, and the triangle wire detection method includes a regular triangle and / or an inverted-triangle wire detection method. A wire winding pulley detection device is provided, pulley winding detection can be completed separately by means of a regular triangle pulley winding detection system and an inverted-triangle pulley winding detection system, and meanwhile, the double systems can carry out pulley winding detection simultaneously according to needs.

Description

technical field [0001] The invention relates to a detection method of an electric power system, in particular to a detection method of a wire passing a pulley. Background technique [0002] The electric power industry is the basic industry of the national economy and the people's livelihood. The continuous and rapid growth of electricity demand has further accelerated the speed of electric power development. Optimizing the allocation of energy resources, ensuring national energy security, and providing high-quality, safe and reliable power supply for national economic and social development are important missions of the power industry to serve the society and build a harmonious society. [0003] In the process of erecting transmission lines, the wires pass through multiple pulleys one after another. If the stranding process of the wires or the unwinding machinery and technology are not suitable, the wires will be damaged to varying degrees in the process, such as loose stra...
