Further, described slidingtype grounding wire device comprises the free bearing be connected with turning rolls, the brace summer hinged with free bearing, be arranged on the sliding contact block of brace summer one end, be connected to the spring between the brace summer other end and turning rolls, and the wedge shape regulating block be clamped between brace summer and sliding contact block, the pin joint between described free bearing and described brace summer is near sliding contact block end;
Further, the material of described sliding contact block is high-density graphite.
The beneficial effects of the utility model are:
1, in the utility model, the material of sliding contact block is that high-density graphite, its electrical and thermal conductivity performance are good, good toughness, and there is good self-lubricating function, arc scratch can not be produced with tower cylinder steel plate, cylindrical shell mother metal is played a protective role, and coal tar pitch or other material in high-density graphite electrode material, can be mixed with, make its loss little, deformation resistant, can use for a long time, save material, economical and practical;
2, add balancing weight in one end of brace summer, sliding contact block and tower socket joint can be made to touch tightr, the mode of spring elongation also can be adopted to increase the contact dynamics of sliding contact block and tower cylinder;
3, wedge shape regulating block can regulate effective contact area of sliding contact block and tower cylinder, is applicable to the needs during welding of different-diameter tower cylinder.
