The specific operation of the tightening device to verify the tightening effect is as follows:

1) The air bag tightening device is transferred to the specified position of the test bed under the matching of the crane and the lifting appliance, and then the tightening device bottom plate 2 is installed on the test bed by using bolts and T-shaped nuts. The air bag 18 is transferred to the installation area using a crane in conjunction with the spreader and a cut-off line is drawn at the corresponding location on the test stand.

2) And (3) penetrating through the buckles at the corresponding positions of the air bag 18 by using the tightening straps 5, then respectively bypassing the first guide pipe 7 and the second guide pipe 8, and finally fixing one end of the tightening straps 5 on the connecting rod of the first fastening pile opening I4 and fixing the other end of the tightening straps 5 on the second fastening pile 20.

3) The harness 6 is secured at one end to a third anchor 21 and at the other end to a fourth anchor 22 using a loop of the harness 6 passing through the corresponding location of the air-bag 18. Meanwhile, in order to ensure the tightening effect, a row of buckles on the air bag 18 are connected with the fifth fastening pile 26 by using an anti-rotation binding belt, so that the air bag 18 is prevented from rotating during the tightening process to influence the tightening effect.

4) The inflation head is used to inflate the air bag 18, and the inflation is stopped when the air pressure inside the air bag 18 reaches the requirement. The end of the air bag 18 and the traction rod 12 are respectively connected after passing through the second pulley 15, the third pulley 20 and the third guide pipe 9 by using a second traction rope 24, and are fixed on the traction rod 12 by using a second limiting block 25.

5) After 2 first hauling ropes 16 are respectively butted with the hauling rod 12, the rope ring is fixed by a first limiting block 13, the 2 first hauling ropes 16 pass through a first pulley 14, and finally the 2 first hauling ropes 16 are gathered and butted with a hauling device 17.

6) The air bag 18 is removed to realize air release, after the air in the air bag 18 is exhausted, the traction device 17 is operated to drive the guide roller 10 to move downwards through the first traction rope 16, and the traction rod 12 moves downwards along with the guide roller 10 to drive the tightening strap 5 to tighten the air bag 18 in the direction within the cut-off line by double the stroke. Meanwhile, the traction rod 12 drives the end of the air bag 18 to be tightened towards the middle through the second traction rope 24 in the descending process.

After the tightening test is finished, whether the balloon body of the airbag 18 is completely pulled within the cut-off line is evaluated to verify whether the tightening device meets the predetermined tightening effect requirement.

When the air bag 18 is inflated, the tightening strap 5 is gradually restored to its original shape as the air bag 18 is inflated, and the traction rod 12 is moved upward to its original position by the tightening strap 5 and the second traction rope 24.

According to the method, the designed tightening device can achieve the effect of tightening the air bag 18 without operating the air bag 18 by personnel in the area near the air bag 18 under the set working condition according to the introduced test scheme, and the normal operation space of other equipment in the system is ensured.

The tool is novel in structure, and the structure of the tightening device is obtained by reducing the weight of the tightening device by adopting a topological optimization method. The air bag tightening device has the advantages that the air bag can be tightened remotely by designing the device under the working condition that personnel cannot enter the area near the air bag, the engineering problem that the existing remote air bag tightening scheme and the structure of an operating device are not provided is effectively solved, and the air bag can be tightened to be verified without approaching the air bag by the operating personnel in a real feasible manner.
