[0026] Figure 1 to Figure 3 A tension balancer 100 for overhead lines is shown. figure 1 The state where the tension from the overhead wire is not applied, or the state where the tension is weak even if the tension of the overhead wire is applied, and the output shaft is not pulled out is shown. Moreover, from figure 1 The state where the overhead wire is slightly pulled to the right in the figure and the spring is slightly extended is shown in figure 2 , and then, from figure 2 The state where the overhead wire is slightly pulled to the right in the figure, and the spring is slightly extended is shown in image 3 .
[0027] The tension balancer 100 for overhead wires includes a coil spring assembly 140 . The coil spring assembly 140 is a tension generating unit using a coil spring. The coil spring is housed inside the cylindrical member, and when the output shaft is pulled out, the coil spring is compressed, and the output shaft is generated unde...

[0053] (structure)
[0054] Figure 5 A tension balancer 200 for trolley lines is shown. Tension balancer 200 for overhead lines with figure 1 The designs of the tension balancer 100 and the linkage mechanism for the overhead lines are different. The tension balancer 200 for overhead lines includes a link member 190 . The link member 190 has a structure in which link member pieces 191 a and 191 b , which are substantially triangular plate-shaped members, are joined by a shaft member 193 and a joining member 197 . The top end of the output shaft 109 is rotatably connected to the center of the coupling member 197 . The shaft member 193 is a shaft member for rotatably attaching the link member 190 to the fixing member 131 . The link member 191 is rotatable in the XZ plane with the shaft member 193 as a rotation center.
[0055] The link member 190 is rotatably connected to the connection arms 195a, 195b at the shaft portions 194a, 194b. A trolley wire connection rod 196 is...

[0061] Image 6 A tension balancer 300 for trolley lines is shown. Image 6 (A) is a stage before the trolley wire (not shown) is stretched in the right direction in the figure by the tension balancer 300 for trolley wire, Image 6 (B) Tension balancer 300 for overhead lines from Image 6 The state of (A) is a state in which the trolley wire (not shown) is pulled in the right direction in the figure, and the double link arm 115 is moved in the right direction in the figure.
[0062] In the tension balancer 300 for trolley wires, the tension generating units are disposed substantially vertically, so that the output shaft 109 protrudes substantially vertically upward from the coil spring assembly 140 . In addition, the reference signs are the same as figure 1 same part and with figure 1 The parts described in relation to each other are the same. The tension balancer 300 for trolley wires includes a coil spring assembly 140 arranged substantially vertic...
