As shown in FIGS. 1 to 3, 6, and 9, the third member 4 includes a mounting plate 19 for fixing the upper end of the insulator 5 with a bolt 22 and a suspension 20 fixed thereon. To do.
[0013]
The suspension 20 is made of a channel-type steel material having an upper side wall 201 and left and right side walls 202 and 203. The upper side wall 201 is disposed below the upper side wall 101 of the second member main body at an interval, and the left and right side walls 202 and 203 are pivots that penetrate the left and right sides along the left and right side walls 102 and 103 of the second member main body. 21 (FIGS. 1 to 3). The upper side wall 201 includes a swing bolt 204 extending upward. The swing bolt 204 passes through the bolt through hole 101c of the second member body 10 so as to swing freely in the front-rear direction, and is disposed between the adjustment bolts 16 and 17. In FIGS. 6B and 9, 202a is a shaft hole through which the pivot 21 passes. 6A and 9, reference numeral 19a denotes a bolt insertion hole, through which the insulator fixing bolt 22 is inserted.
[0014]
Therefore, the support bracket 1 is attached to the side surface of the beam B by fixing the base plate 7 of the first member 2 with the fixing bolt 9. At this time, in order to roughly determine the vertical position of the trolley wire T, the position of the fixing bolt 9 with respect to the vertical long hole 7a of the base plate 7 is appropriately selected to adjust the mounting position of the support bracket 1 up and down. The vertical position of the trolley line T can be further finely adjusted by changing the vertical position of the second member 3 relative to the first member 2. This fine adjustment is performed by adjusting the screwing depth of the height adjusting bolts 14 and 15 with respect to the second member 3 and changing the relative position of the horizontal through bolts 13 with respect to the upper and lower elongated holes 83a and 84a of the first member 2. Do. Adjustment of the front and rear position of the trolley wire T is performed by adjusting the screwing depth of the bolt 18 with respect to the partition plate 12 and changing the relative position of the horizontal through bolt 13 with respect to the front and rear elongated holes 102a and 103a of the second member 3. . Furthermore, the adjustment of the fixed angle of the trolley wire T with respect to the beam B is performed by adjusting the attachment angle of the third member 4 with respect to the second member 3. This adjustment is performed by adjusting the screwing depth of the adjusting bolts 16 and 17 of the angle adjusting bracket 11 and changing the inclination angle of the swing bolt 204 between the two bolts.
