Embodiment 1

[0093] Various combinations of the leak-stopping block 110 and the sealing assembly 300 are used alone, and this situation is suitable for a cylinder with a small diameter, and the use of the leak-stopping block 110 alone can form a smaller clamp between the rope and the leak-stopping block 110 At this moment, the compression force of the rope to the leak blocking block 110 is also relatively large.

Embodiment 2

[0095] Various combinations of heightened leakage blockage block 220 and sealing assembly 300 are used alone. This situation is applicable to the larger diameter of the cylinder. Using heightened leakage blockage block 220 alone can also form a gap between the rope and the leakage blockage block 110. Smaller included angle, at this moment the pressing force of rope tool is also bigger to the heightening plugging block 220.

Embodiment 3

[0097] Various combinations of heightened plugging block 220, plugging block 110 connection setting and sealing assembly 200, this situation is applicable to the larger diameter of the cylinder, using the combination of heightening plugging block 220 and plugging block 110 connection setting Only then can a smaller angle be formed between the rope and the plugging block 110 , and at this moment, the rope can form a larger pressing force on the plugging block 110 through the heightened plugging block 220 .

Abstract

The invention discloses a modular combined under-pressure emergency leaking stoppage tool and method. The modular combined under-pressure emergency leaking stoppage tool mainly comprises a leaking stoppage module and a rope tensioning-locking mechanism, the rope tensioning-locking mechanism is connected with the leaking stoppage module through a rope, the leaking stoppage module is close to a leaking position, and a leaking stoppage block is pressed at the leaking position of a barrel body through pushing of the rope tensioning-locking mechanism, and then plugging is formed. According to the modular combined under-pressure emergency leaking stoppage tool and method, a clamping jaw is arranged on the rope tensioning-locking mechanism, locking and loosening of the rope by the clamping jaw can be manually achieved without tools such as a wrench, breakage of the rope is avoided, and the plugging time of a leaking opening is effectively shortened; and secondly, the height of the leaking stoppage block is increased, and the plugging effect can be achieved more effectively.

Description

technical field [0001] The invention relates to the technical field of leak plugging devices, in particular to a modularized combined pressurized emergency leak plugging tool and method. Background technique [0002] Tank trucks with pressure tanks are the main way of road transportation of hazardous chemicals. Due to factors such as rollover, rear-end collision, scratching, medium corrosion, welding defects, and damage to sealing materials, tank trucks are prone to damage, which will cause leakage, combustion, and explosion accidents of dangerous chemicals, which will bring harm to the lives and property of the people. to uncontrollable losses. The barrel is the main part where the tanker is damaged. In response to leakage accidents of tank trucks with pressure tanks, firefighters generally use bundled leak plugging tools for emergency plugging. The bundled plugging tool is mainly composed of plugging block (or plugging module), rope (wire rope, strap), rope tightening-l...
