Cantilever is pour arched bridge and is hung basket top pushing -type track tankette running gear

The utility model relates to a cantilever is pour arched bridge and is hung basket top pushing -type track tankette running gear. The cantilever is pour the basket of hanging of arched bridge and is selected down the formula of holding to fall the triangle to hang the basket, and string basket overall structure is at the concrete structure downside, installation track tankette on string leg of string basket, the support setting is on hanging string leg of basket before the jack to be connected with hydraulic jack, the fulcrum sets up the back pulley after hanging the basket girder. The utility model discloses successfully solved the low technological problem of string basket operating efficiency, changed into track roll walking with the great slip walking of traditional frictional force, pushed up the motive force with continuous jack again, reduced the operation of the frequent conversion of counter -force dog, improved the inversion greatly and hung a stability and the speed that the basket moved. More traditional finish rolling screw -thread steel pulls to be compared, and hydraulic jack top pushes away the effect, avoids finish rolling screw -thread steel brittle fracture risk, and the top pushes away the effort distance and shorten, hangs skew about can of basket, avoid with the arch ring scraping, the walking is stable, safety.
