[0055] The guide rod 41 guides the synchronous lifting assembly 5 to move vertically downward, and the guide seat 42 prevents the guide rod 41 from moving further downward, thereby limiting the movement of the guide rod 41.

[0056] Two sets of parallel guide assemblies 9 are installed below the mounting top frame 6; the guide assembly 9 includes a second transverse guide rail 91, an arc guide rail 93 and a third transverse guide rail 94 which are fixedly connected in sequence; a plurality of straight connecting plates 92 are fixedly connected to the second transverse guide rail 91, and the top of the straight connecting plate 92 is fixedly connected to the mounting top frame 6;

[0057] The movable connecting assembly 8 is first conveyed to the third transverse guide rail 94 by the suspension conveyor line 7, the movable part of the movable connecting assembly 8 is inserted into the guide rail groove of the third transverse guide rail 94, the movable part of the movable connecting assembly 8 is driven by the suspension conveyor line 7 to move to the arc guide rail 93 under the guidance of the third transverse guide rail 94, the movable part of the movable connecting assembly 8 is driven by the suspension conveyor line 7 to move to the second transverse guide rail 91 under the guidance of the arc guide rail 93, and the movable part of the movable connecting assembly 8 is driven by the suspension conveyor line 7 to move to the first transverse guide rail 51 under the guidance of the second transverse guide rail 91;

The movable connection assembly 8 is driven to move by the suspension conveyor line 7. Under the guidance of the third transverse guide rail 94, the cross bar 85 is driven to be inserted into the arc guide rail 93. Since the arc guide rail 93 is an arc structure, the cross bar 85 gradually moves upward, and the cross bar 85 drives the sleeve plate 83 to slide upward and shrink along the straight plate 82. After that, under the guidance of the arc guide rail 93, the cross bar 85 is driven to be inserted into the second transverse guide rail 91;

[0063] Afterwards, since the second transverse guide rail 91 is flush with the first transverse guide rail 51, the two sets of transverse rods 85 are respectively inserted into the guide rail grooves of the front and rear sets of the first transverse guide rails 51 under the guidance of the second transverse guide rail 91;

[0065] The present invention adopts a straight suspension conveyor line 7 to drive the movement of the hanger 3, and there is no need to install a movable arc track. The installation is convenient, the structure is simple, and the equipment cost is low.
