The conversion oil cylinder is in a locking state. The hook pulls the bracket 20 by means of the sling and triangle 51 and the crane remains pulled. The second rotating shafts 24 on two sides of the supporting disc 23 at the bottom of the arrow body 1 are rotatably arranged on the step structure 2142, and two rib plates limit and fix the supporting disc 23. The two safety support legs 40 are located at two sides of the bracket 20, when the bracket is in a horizontal position, the safety support legs 40 are in a recovery position and are pivotally fixed at two sides of the bracket 20, the first rotating shaft 22 of the support frame 21 rotates in the arc-shaped notch, the arrow body is turned over and erected along with the bracket, when the arrow body is erected to a preset position, the crane stops working, the safety support legs 40 are opened, the safety support legs are turned over for 180 degrees and then are in a supporting position, and at the moment, the triangular support body 41 is connected with the left pull rod and the right pull rod to limit left and right displacement of the bracket 20. The lifting height of the supporting legs 42 is adjusted to enable the supporting legs 42 to be in contact with the ground, so that an independent supporting effect can be achieved. The crane slowly releases the pulling force until the hanging belt is in a loose state. The switching cylinder is opened to separate the pin shaft barrel from the triangle, and the crane slowly tightens the hanging belt. Like this, the arrow body erects the device can guarantee that fixed fuel arrow body erects gently, and the atress is even, can solve the problem that the direct hoist and mount upset is not suitable for to the large-tonnage combined material arrow body.
