Therefore, when the whole lifting appliance is controlled to laterally move, the lateral movement operation can be completed only by operating the lateral movement oil cylinder, and any operation is not required to be performed on the telescopic oil cylinder, so that the center distance L1 of the two lifting columns controlled by the telescopic oil cylinder is fixed, and the lifting appliance structure provided by the application can be used for completing accurate and flexible hanging operation.
2. Operation process for switching 40 feet standard container into 20 feet standard container
When the lifting appliance needs to be switched from a standard container with 40 feet to a standard container with 20 feet, a technician controls the left telescopic cylinder 521 to pull the left telescopic arm 511 to move rightwards, and operates the right telescopic cylinder 522 to pull the right telescopic arm 512 to move leftwards, so that the lifting appliance is retracted to the center size of the left lifting column and the right lifting column to be L2. At this time, the side-shifting oil cylinders are driven to coincide the center of the mobile trolley with the center of the slide trolley, so that the standard container slings of 40 feet of the stacker crane are positioned at the center (shown in figure 4), and all the oil cylinder inlets and outlets are locked to hang the standard container of 20 feet.
After the hanging operation is completed, the side shifting operation is carried out on the lifting appliance, and the specific steps are as follows: if the left side moves 600, only the side moving oil cylinder is required to be operated to move 600 leftwards for the moving trolley 4, and the moving trolley 4 drives the left telescopic oil cylinder 521 and the right telescopic oil cylinder 522 arranged on the moving trolley to move leftwards, the left telescopic oil cylinder 521 draws the left telescopic arm 511 to move 600 leftwards, and the right telescopic oil cylinder 522 draws the right telescopic arm 512 to move 600 leftwards for the side moving mechanism; otherwise, the right side shifting 600 can be realized by operating the right side shifting cylinder to shift 600 to the right. The moving operation can be completed by only operating the side-moving oil cylinder, so that the center distance L2 of the two suspension columns controlled by the telescopic oil cylinder is fixed, and the operation state is shown in fig. 4.
