DPK32型铺轨机由主机(一号机)、二号机、倒装龙门吊组成。其中主机用于铺设轨排;二号机用于转运轨排;倒装龙门吊由前、后龙门吊组成,用于吊运轨排。由于该型摊铺机机体体积庞大,且为焊接件,所以控制焊接变形成为制作工艺的关键。1.机体结构主机机体由侧梁、枕梁、端梁、牵引梁、横梁及纵梁组成,如图1所示。机体长28m,是主要承力部件,可 DPK32-type track laying machine from the host (a machine), on the 2nd machine, flip gantry crane components. One host for the laying of rail; No. 2 for transport rail row; flip gantry crane by the front and rear gantry crane components for the hanger rails. As the paver body is bulky and is a welded part, controlling the welding deformation becomes the key to the manufacturing process. 1. Body Structure The body of the main body by the side beams, bolster, end beams, traction beams, beams and stringers composition, shown in Figure 1. Body length 28m, is the main load-bearing components can be
