The cylinder is the main part of the tank truck which is damaged. Aiming at the barrel leakage accident of the tank truck with the pressure tank, a fireman generally adopts a binding type plugging tool to carry out emergency plugging. The binding type plugging tool mainly comprises a plugging block (or a plugging module), a rope (a steel wire rope and a binding belt), a rope tensioning-locking device, a power source and accessories thereof and the like, and the using method comprises the following steps: firstly, the plugging block is tightly pressed on a leakage part; secondly, binding a rope to the barrel, wherein one end of the rope is placed in a groove on the outer side of the leakage blocking sheet, and the other end of the rope is arranged on a rope tensioning-locking device; secondly, connecting the power source and accessories thereof with the rope tightening-locking device, and then driving the power source to tighten the rope until the leakage is avoided; finally, the harness cord-lock is operated to define the position of the harness and the power source and its accessories are removed.

The existing plugging block 110 has a groove on the outer end surface for matching with the rope 500, and a plugging rubber 330 or a sealing pad 320 is adhered on the inner end surface. Although the plugging block 110 can realize emergency plugging in a partial leakage scene, there are many disadvantages: one is that the required height of the plugging block 110 is not taken into account. In order to convert the tensile force of the string 500 into the pressing force as much as possible, the angle θ (shown in fig. 2) between the plugging block 110 and the string 500 should be as small as possible. In order to achieve the above purpose, there is a certain height difference between the contact position of the plugging block 110 and the rope 500 and the leakage. In addition, some leak points, such as leak point B (shown in fig. 2), affected by the barrel attachment 410 also need to have a certain height of the block 110 for plugging, so as to ensure that the rope 500 is in contact with the block 110. Secondly, the rope device 500 installed in the groove can slide when being tensioned, so that the leakage stoppage module can slide. Thirdly, due to the lack of operating accessories, the operator is difficult to press the plugging block 110 to the leakage position under the action of the spraying pressure of the leakage medium.
Therefore, a binding type leakage stopping tool which can more effectively convert the tensioning force of the rope into the pressing force is needed to meet the requirement of fire fighting teams for emergency leakage stopping of the cylinder body of the tank truck with the pressure tank.
