A U-shaped hanging ring for automatic identification of inspection image defects

Abstract

The invention relates to a U-shaped hanging ring facilitating automatic identification of inspection image defects, and belongs to the technical field of electric power fittings. According to the invention, the curvature radiuses of hanging lugs are different, a large gap is reserved in the upper part of the hung hardware fitting, automatic downward moving and micro sliding can be achieved, relative torsion is allowed, the stress state can be improved, and local abrasion and fatigue are relieved. The left part of a through hole of a second hanging plate is wider than the right part of the through hole, and transverse movement of a bent bolt can be avoided. The second end of the bent bolt cannot penetrate out of a through hole of a first hanging plate, a safety pin surrounds the hanging lug, and accidental falling can be avoided. The bent bolt is close to the right relative to the lower straight section and the upper straight section at the middle straight section, so that a working position and a stressed state are automatically kept, and hinged cross arm hanging points or other fittings are allowed to deflect up and down without interference. The hanging lugs and the bent bolt are all provided with cutting planes and dents, so that the structural strength can be improved, and light weight is promoted. Due to the dents, shot images are clear, and a computer can conveniently and automatically determine the defect level; and abrasion and deformation algorithms are simple, efficient and high in precision.

Description

Technical field[0001]The invention relates to a U-shaped hanging ring, which belongs to the technical field of electric power fittings.Background technique[0002]U-shaped hanging ring, as a universal connection fitting for power lines, includes a hanging ear and a hanging plate. There are holes on the hanging plate, through which bolts can be inserted, and connected to the cross arm hanging points or the plate holes of other fittings through bolts. In order to prevent the bolt from falling out, a nut and a closed pin are provided at the end of the bolt. Because the U-shaped hanging ring is used for outdoor power lines, it bears the effects of wind, rain, ice, snow, dust and atmospheric corrosion, and the environment is harsh, and the size and direction of the load are complex. Wear, rust, arc burns, closing pins fall off, Defects such as nut retreat and nut shedding will also cause deformation, cracks and fractures, which will affect the safety of power grid operation. Timely inspect...

Problems solved by technology

The existing U-shaped hanging ring design does not consider the automatic judgment of the wear and deformation degree by the computer, which is not convenient for the automatic identification of defects in the inspection image, and needs to be improved
