Embodiment Construction

[0024] Such as Figure 5 , Image 6 As shown, it is a schematic diagram of the overall structure of the present invention used on the Haffle ring, corresponding to the two states of contraction and extension of the double helical propulsion device of the Haffle ring. It can be seen from the figure that the Haffle ring is a ring 2 composed of two half-rings 11, and three double-screw propulsion devices 3 are evenly distributed on the ring 2.

[0025] As for the specific structure of the described twin-screw propulsion device 3, please refer to Figure 7 As shown, it includes a rotating member 31 , a pressing member 32 and an anti-twist member 33 . The rotating part 31 is screwed on the ring part 2 through the first thread pair 311, and the end of the rotating part 31 protruding from the outer side of the ring part 2 is the twisting end 312, and the end extending into the inner side of the ring part 2 is then The second thread pair 313 is screwed to the pressing member 32 . ...

Abstract

The invention relates to a double-helix propulsion device for a leak-stopping tool, which uses its double-helix structure to quickly fix the leak-stopping tool on a pipeline, and quickly pushes the device against a leak-stopping piece. The device is arranged on a body, and the double-screw propulsion device includes a rotating member, a pressing member and an anti-twist member; the rotating member is screwed on the body through a first thread pair, and one end of the rotating member It is the twisting end, and the other end is screwed to the pressing member through the second thread pair, the helical direction of the first thread pair is opposite to that of the second thread pair, and the middle part of the anti-twist member is passed through the On the above-mentioned resisting piece, the two ends of the anti-twist piece are slidably connected with the above-mentioned body. Every time the twisting end of the rotating member is twisted one turn, the pressing member advances two pitches relative to the body, which shortens the tightening time to half of the original, thereby speeding up the plugging speed.

Description

technical field [0001] The invention relates to a double-screw propulsion device used in leak plugging, in particular to a device that uses a double-helix structure to quickly fix a leak plugging tool on a pipeline and rapidly pushes a top-press leak plugging piece. Background technique [0002] Medium leakage often occurs in pressure vessels or pipelines that store and transport hazardous chemicals. Once the toxic and harmful medium leaks, it will have a very bad impact on social property, life safety and the natural environment. Therefore, it is necessary to plug the container as soon as possible. [0003] At present, the method for emergency plugging of container leakage points is to find a fixed point near the leakage point of the pressure vessel or the outer wall of the pipeline to fix the plugging tool, and use this as the point of action of the force in the extension direction of the top pressure device. Press the plugging sheet with plugging glue on the leak point, a...
