Combined interlayer pulley vertical hinged lead door and corresponding planer steel plate track

The invention relates to a combined interlayer pulley vertical hinged lead door and a corresponding planer steel plate track. The body of a vertical hinged lead door is divided into two layers, i.e. a covering layer (1) and an embedding layer (2), which are connected by a steel connecting frame layer (3), in thickness direction. The covering layer is slightly larger than a door way in area, and the embedding layer and the steel connecting frame layer are slightly smaller than the door way in area. Pulleys (9, 10) moving along the direction vertical to the inner and outer faces of the lead door are respectively arranged on left and right edges of the lower side of the steel connecting frame layer, and a power system (15) is arranged above the pulleys on the moving side of the lead door. A reinforced concrete base with the thickness more than 20cm is poured below the lead door moving scope and on the ground in a certain range around the lead door moving scope, parts of two pulley tracks (11, 12) of the lead doo
