我公司1台SCC6500型650t履带起重机,在施工过程中其6m长的副臂架不慎被压弯,致使左侧2根主弦管挤压变形。其中1根上主弦管扭曲变形且内凹严重,1根下主弦管受立杆挤压发生弯曲变形,1根腹管弯曲变形(见图1)。现介绍其修复工艺。1.确定修复方案(1)上主弦管上主弦管变形较大,变形部位长度约650mm,需割除变形部位并更换新管。有4根腹管与该部位主弦管连接,为此需将4根腹管切割开。
I company 1 SCC6500 650t crawler crane, during the construction of its 6m long jib inadvertently bends, resulting in the left two main chord extrusion deformation. One of the upper main chord twisted and deforming seriously, a lower main chord bent by the pole bending deformation, an abdominal tube bending deformation (see Figure 1). Now introduce the repair process. 1. Determine the repair program (1) on the main chord on the main chord deformation, deformation of the length of about 650mm, need to remove the deformation of the site and replace the new tube. There are 4 abdominal tubes connected to the main chord of this part, so 4 abdominal tubes need to be cut open.
