Document Type and Number:
Japanese Patent JP7204333
Kind Code:
B2
Abstract:
To provide a trolley wire flexure device that can bend the trolley wire with high precision and easily change the bending angle.SOLUTION: The holding members 2, 2 that hold the trolley wire T at intervals are pivoted on the middle frame board 1a of a frame body 1. Facing to the central part between the gripping members 2,2 on the upper frame plate 1b of the frame body 1 from above to support a pressing member 3 which bends by pressing down the central part of the gripping portion of the trolley wire T by hydraulic drive. The gripping member 2 is pivoted rotatably to the intermediate frame plate 1a along the bending of the trolley wire T by a horizontal rotating shaft 9, and is configured with a base body 5 and a pressing lid 6 that can be opened and closed so as to sandwich the trolley wire T by a hinge portion. The base body 5 and the pressing lid 6 are provided with horizontally extending receiving grooves 6b, 8a for receiving the trolley wire T which comprises engaging protrusions 6c, 8b corresponding to both engaging grooves of the trolley wire T on the inner sides facing each other. On the lower frame plate 1c of the frame body 1, a height-changeable stopper 4 is erected so as to face the pressing member 3 in the vertical direction and restrict the position where the trolley wire T is pushed down by the pressing member 3.SELECTED DRAWING: Figure 6
