摘要： PROBLEM TO BE SOLVED: To provide a metallic stranded wire connecting pipe such as a parallel branch connecting pipe formed to prevent slip-out of a branch line caused by the corrosion of members due to corrosion potential difference between the members, and an accident or the like caused by the severance of wire of a feeder. SOLUTION: A metallic stranded wire connecting pipe body 1 has a first connecting hole 11 for inserting hard aluminum stranded wires 4 of a feeder, and a second connecting hole 12 for inserting hard copper stranded wires 5 of a branch line or the like. The hard aluminum stranded wires 4 and the hard copper stranded wires 5 are inserted in the first connecting hole 11 and the second connecting hole 12 respectively, and pressure-bonded to electrically connect the stranded wires 4, 5 to each other. The metallic stranded wire connecting pipe body 1 is formed of an aluminum-based metal, and the hard copper stranded wires 5 are pressure-bonded through a sleeve 2 formed of a copper- based metal, and an intermediate metal layer 3 formed of metal with intermediate corrosion potential of copper-based metal and aluminum-based metal.

摘要： PROBLEM TO BE SOLVED: To retain a trolley line at a prescribed height position by fitting an arm on the inner periphery side of a curved passage, which is capable of oscillating in horizontal and vertical directions relative to an arm supporting metal fitting and clamps the trolley line at its front end, and disposing a spring unit which activates pushing-up force at the arm. SOLUTION: In this arm 6, an ear 9 is fixed at its front end so as to clamp a trolley line 10, and a spring fixture 11 is fixed at its front part. A catenary line M is formed at the upper position of the trolley line 10, and the catenary line M is supported by a catenary line supporting pulley K fitted at a main pipe PI. By rotating an adjusting nut which is screwed in the lower end part of a rod 71, the pushing-up force of the arm 6 caused by a spring is adjusted, so that desired pushing-up force acts on the trolley line. The arm 6 oscillating in the horizontal direction is restored at a specific position by a restoring mechanism, and the trolley line 10 is retained at a specific position.

摘要： PURPOSE:To absorb oscillation of a trolley line at the time of passing a pantograph by way of connecting with a space between an auxiliary catenary wire and the trolley line. CONSTITUTION:In a cylinder 1 suspended and supported by an auxiliary catenary wire, a piston 6 having a piston ring 14 with an oscillation absorbing function by frictional resistance force is inserted so as to receive spring pressure. Thereafter, through a piston rod 8 of this piston 6, an ear piece 9 to sandwich and suspend a trolley line T is provided. Consequently, oscillation which the trolley line T receives at the time of passing a pantagraph is absorbed.

摘要： PURPOSE:To suspend an auxiliary catenary wire for an electric railway easily and so that it follows flow of a catenary line without resistance. CONSTITUTION:A support metal fitting of an auxiliary catenary wire M is pivotally installed on a head end of an auxiliary arm constituting a pull-off through a shaft free to oscillate in the horizontal direction. This support metal fitting is constituted of two support fitting pieces 6A, 6B each of which is furnished with a stepper piece one end of which is pivotally installed and which opens and closes within a previously specified angle. Additionally, a holding surface of the auxiliary catenary wire M is formed to respectively face insides of both of these support metal fitting pieces 6A, 6B, and both of the support metal fitting pieces 6A, 6B are fastened with a bolt between them. Consequently, even when the fastening bolt is loosened and falls, the auxiliary catenary wire is supported by the support metal fitting and hardly falls.

摘要： PURPOSE:To support a trolley line by way of absorbing pushing-up and flowing actions added by passing of an electric railcar. CONSTITUTION:Each of base ends of a main arm 5 sandwiching a trolley line T on its head end and an auxiliary arm 6 supporting a catendry wire M is respectively pivotally installed on brackets 2, 3 with an axis in the horizontal direction. Each of these arms 5, 6 is made to oscillate in the vertical direction, and each of these brackets 2, 3 is supported by a shaft 4 passing through in the longitudinal direction on an arm support metal fitting 1 free to oscillate in the trolley line flow direction. Additionally, a spring mechanism 8 of the base end part of the main arm 5 is supported between the main arm 5 and the bracket 2. Consequently, following the flow of the trolley line T, the main arm 5 and the auxiliary arm 6 are smoothly oscillated in the horizontal direction without rattling, oscillate in the vertical direction against push-up of the trolley line and can carry out stable support.

摘要： PURPOSE:To prevent separation of a pantograph from a trolley line by locating a disc spring in the middle of a hanger bar and absorbing vibration of the trolley line during the passage of the pantograph. CONSTITUTION:A hanger supported in a hanging state on a suspension line M is divided into an upper hanger 1 and a lower hanger 7 having an ear piece 2. A resilient cushioning body 8 is interposed in a connection part between the upper and lower hangers 1 and 7 so as to connect them together. This constitution absorbs vibration generated during the passage of a pantograph and prevents the occurrence of separation of the pantograph from a trolley line.
