A carbon fiber wire installation tightening device

Abstract

The invention discloses a wire tightening device for carbon fiber wire mounting. The wire tightening device is used in the field of carbon fiber wire mounting and comprises a hanging plate, a main brake rod, a main pressing block and a traction mechanism, wherein the top end of the hanging plate is provided with a pressing edge, the upper end of the main brake rod is hinged to the pressing edge, the main pressing block is hinged to the middle portion of the main brake rod, and the traction mechanism is used for pulling the main brake rod to swing forwards. A guide groove parallel to the pressing edge is formed in the position, at front of the main brake rod, of the hanging plate. The traction mechanism includes a hinge pin, a pull rod and a main connecting rod, wherein the hinge pin can slide in the guide groove forwards and backwards, one end of the pull rod is hinged to the hinge pin, and the two ends of the main connecting rod are hinged to the lower end of the main brake rod and the hinge pin respectively. When the wire tightening device is used, the hanging plate is hung on a wire through the pressing edge, the pull rod is pulled forwards through wire tightening tensile force, the pull rod drives the main brake rod to swing forwards through the main connecting rod, the main brake rod drives the main pressing block to press the wire tight on the lower side of the pressing edge, and therefore traction, of the wire tightening tensile force, on the wire is achieved. Due to the fact that the main pressing block and the pressing edge are mutually pressed tight, the contact area between the main pressing block and the wire is increased. Therefore, the surface of the wire is prevented from deforming when the wire is tightened in the process of mounting.

Description

Technical field [0001] The invention is used in the field of carbon fiber wire installation, and particularly relates to a carbon fiber wire installation tightening device. Background technique [0002] Carbon fiber composite wire is a high-strength carbon fiber composite power transmission wire, which includes a core and an annular conductive layer wrapped around the core. The core is a conductive core composed of carbon fibers or a composite conductive core composed of carbon fibers. The ring-shaped conductive layer is composed of copper, aluminum, and aluminum alloy wires tightly wrapped around the periphery of the core. The outer periphery of the ring-shaped conductive layer is generally covered with an insulating layer. Carbon fiber composite power transmission wire is a new structure of energy-saving capacity-increasing wire, which is mostly used for overhead lines. Compared with conventional wires, it has light weight, high tensile strength, good heat resistance, low ther...

Problems solved by technology

[0003] When installing carbon fiber conductors, most of them use conventional steel-reinforced aluminum stranded wire tensioners. Since carbon fiber conductors use soft aluminum as the conductor, the contact area between conventional steel-reinforced aluminum stranded wire tensioners and carbon fiber conductors Smaller, it is easy to deform the aluminum conductor of the carbon fiber wire, which will cause the surface of the wire to be uneven and affect the use of the carbon fiber wire
