The both ends of the jar body bear respectively on upset chain 10, when upset motor 8 starts, upset sprocket 9 drives an upset chain 10 and rotates, just can make the jar body overturn through the frictional force between the upset chain 10 and the jar body, above-mentioned mechanism easy operation, safe in utilization, convenience are designed to anomalous large-scale member, the upset of large-scale steel members such as mainly used special-purpose vehicle, and this equipment is the important equipment in the steel construction production, also is the essential equipment that improves production line degree of automation.

Further, in order to place the tank workpiece into the turnover chain 10, as shown in fig. 3, driving cylinders 11 are installed at two ends of the connecting plate 7, a connecting rod 12 is installed on a piston rod of each driving cylinder 11 in a hinged manner, the connecting rod 12 is installed on the connecting plate 7 in a hinged manner through a rotating shaft 13, a poking rod 14 is further installed at one end of the connecting rod 12 far away from the driving cylinders 11, and the poking rod 14 can drive the turnover chain 10 to move. When the piston rod of the driving cylinder 11 extends out, the poking rod 14 can open the turnover chain 10, after the tank workpiece is placed in the turnover chain 10, the piston rod of the driving cylinder 11 is retracted, the poking rod 14 is separated from the turnover chain 10, and the turnover chain 10 is in a bearing state.

Furthermore, the protection block is arranged on the overturning chain 10, so that the tank body can be prevented from being scratched in the overturning process.

At the jar body and following upset chain 10 pivoted in-process, because the shape of the jar body is various, jar body focus behind the central point of skew device, under the action of gravity, the upset speed of the jar body can rise rapidly, not only can bring the damage simultaneously for upset chain 10 and jar body, still can influence subsequent welding operation, also can make jar body self violate the upset requirement and take place anticlockwise rotation, for avoiding above-mentioned circumstances, make the jar body can be under the prerequisite that has the support, the upset of assigned direction is accomplished to slow speed, all install jar body upset complementary unit on the stand 6. As shown in fig. 4, the auxiliary mechanism for turning over the can body comprises a rotating arm 15, one end of the rotating arm 15 is hinged to the upright post 6, a friction roller 16 is installed at the other end of the rotating arm 15, a friction protrusion 17 is arranged on the periphery of the friction roller 16, a torsion spring 18 is arranged on a rotating shaft at one end of the upright post 6, the torsion spring 18 always tends to enable the friction roller 16 to press the can body, a one-way bearing 19 is installed on the rotating shaft of the friction roller 16, and the one-way bearing 19 allows the friction roller 16 to rotate along with the can body when the can body rotates along a set direction.
