4 " one leads 2 " overhead line coaster stores pylon, it relates to transmission line engineering apparatus technical field, the V type insulator chain and the fixed connection that wins in successionthat dangles, it is fixed with the gold utensil on winning in succession to dangle, dangle the both sides of winning in succession respectively through the channel -section steel with first two eventhe board is connected, two first two even the board pass through the crossbeam connection, be fixed with two seconds two on the crossbeam and link the board, first two even the lower parts of two company's boards of boards and second have right angle hanging plate through bolted connection respectively, right angle hanging plate's lower extreme is fixed with the three -fold block. 4 " one leads 2" overhead line coaster stores pylon, needing under the independent suspension coaster mode to have avoided the work of adjustment coaster height, be favorable to guaranteeing tight line constructionsag observation quality, the difficult problem that a plurality of coasters were arranged with hanging way is complicated has effectively been solved to the problem of avoiding independent suspensioncoaster mode to need a large amount of rope slings, hanger, multiplexer utensil simultaneously, makes things convenient for construction of the tight line of epilogue and accessory installation to operate.
