A Coating Guide Floating Mechanism Used in Overhead Bare Wire Coating Device

Abstract

The utility model relates to a coating guide floating mechanism used for an overhead bare wire coating device, which belongs to the coating field. It includes a fastening ring structure composed of an upper pressing piece and a lower pressing piece; on one side of the ring structure, a centering component that can move along the outer surface of the overhead wire is arranged to hold the bare overhead wire to be coated and the coated wire. The centering position relationship between the wire outlets of the coating assembly; the hook assembly is set on the same side of the ring structure to establish an elastic connection relationship with the frame of the coating device; the other side of the ring structure is connected to the coating device The coating components in are fixedly connected to form a rigid connection relationship. It ensures that the thickness of the insulating material coating layer coated on the entire outer surface of the overhead wire is uniform by forcing the center of the outlet of the coating component to always coincide with the longitudinal centerline of the overhead wire; eliminating the impact of wire bending deformation on the thickness of the coating layer coming adverse effects. It can be widely used in the fields of transformation and operation management of overhead transmission lines.

Description

technical field [0001] The invention belongs to the field of coating, and in particular relates to a coating guiding device used for an overhead bare wire coating device. Background technique [0002] Overhead transmission lines (also known as overhead wires or overhead lines) are the main way of power transmission. [0003] Due to the large range of transmission lines, the distribution points are wide, the geographical environment is complex, the natural environment is harsh, and the power transmission lines, poles and towers and accessories are exposed to the wild for a long time, often due to external forces, tree branches, high-altitude objects and other objects that may encounter overhead lines Objects close to the transmission wires will adversely affect the safety and efficient power supply; in addition, among the accidents reported by the State Grid every year, the accidents caused by low-voltage electric shock account for the vast majority. [0004] At present, var...

Problems solved by technology

[0008] In actual use, such as figure 2 As shown in , due to the rigid connections (commonly known as hard connections) between the various components of the entire machine, and the machine itself has a certain self-weight, when the machine is actually coating, the longitudinal centerline of the overhead wire There will be a certain angle between x' and the longitudinal centerline x of the coating assembly outlet of the coating machine, that is, the longitudinal centerline of the overhead wire and the longitudinal centerline of the coating assembly outlet are not parallel or coincident, resulting in The plane y where the coating component outlet of the coating machine is located and the longitudinal centerline x' of the overhead conductor cannot maintain a complete vertical relationship, so the thickness uniformity of the insulating material coated on the entire overhead conductor cannot be guaranteed (due to the machine Due to the self-weight of the insulation material, the coating thickness of the insulating material will basically be thin at the top and thick at the bottom), so that the corresponding coating technical requirements and insulation electrical performance indicators cannot be met.
