Multi-joint flexible protective device for wire splicing sleeve to pass through pulley

Abstract

The invention provides a multi-joint bendable protection device for a wire connecting pipe over a trolley, which comprises a main pipe (1), movable joints (2) symmetrically installed on both sides of the main pipe (1), movable joints (2) at both ends and The transition section (3) is connected, and the rubber sleeve (4) passes through the transition section (3), the movable section (2) and the main pipe (1); the main pipe (1) and the movable section (2) are two Composed of semicircular components, the supervisor (1) and the movable section (2), and the movable section (2) and the movable section (2) are movable connections. The invention has reasonable structural design, convenient installation and high strength, and can solve the problem of stress concentration of wires at the end of the protection device in the prior art and the problem of broken wire cores. It can effectively protect the wires from being damaged and has important use value.

Description

technical field [0001] The invention relates to a protection device, in particular to a multi-joint bendable protection device for a wire connection tube passing a pulley for a power transmission line. Background technique [0002] In recent years, with the rapid development of my country's economy, the electricity consumption of industries and residents has been increasing, which has promoted the rapid development of China's power grid, and the operating voltage level of the power grid system has been continuously improved. With the large-scale use of lines, the scale of the network is also expanding. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] At present, during the construction of domestic transmission line wire tension release, it is necessary to crimp multiple wires fro...
