Technical Field

[0001] The utility model belongs to the field of hydraulic pipeline maintenance tools, in particular to a high-pressure liquid pipe pulling pliers. Background Art

[0002] At present, when removing the high-pressure liquid pipe joints underground, especially the hydraulic support fluid supply system, because the high-pressure liquid pipe has been used for a working face, the high-pressure liquid pipe joints are corroded, deformed, and the sealing ring is aging and deformed. The high-pressure liquid pipe of the hydraulic support adopts 3-4 layers of steel wire braided hose with a diameter of not less than 51mm, which is not easy to deform. Therefore, the high-pressure liquid pipe joints need to be replaced separately. When removing the high-pressure liquid pipe joints, after removing the U-shaped pin, the operator uses a wrench hammer to knock and vibrate, shake the high-pressure liquid pipe joint to loosen it. The working space for dismantling the hydraulic support fluid supply system is small, and the personnel cannot exert force, which seriously restricts the withdrawal speed of the working face.

[0003] In view of this situation, it is necessary to design an efficient high-pressure liquid pipe removal device. Utility Model Content
