摘要： An apparatus for attaching abutting ends of first and second coaxial pipe sections together includes a support frame, at least two spaced-part fixed pipe clamping jaws having respective upper and lower jaw halves carried by the support frame for positioning the first pipe section in a fixed position, at least two movable pipe clamping jaws having respective upper and lower jaw halves carried by the support frame for translating movement of the second pipe section relative to the fixed clamping jaws and into aligned abutment with the first pipe section, and a joining device for joining the first and second abutted pipe sections together without interference between the clamping jaws and the pipe sections. The clamping jaw pivots respective fixed and movable upper and lower jaw halves into and out of clamping engagement with the first and second coaxial pipe sections. Fixed jaw pivot pins define a pivot axis of the upper jaw half of each of the at least two fixed clamping jaws and respective movable jaw pivot pins defining a pivot axis of the upper jaw half of each of the at least two movable clamping jaws. The pivot axes of the movable jaw pivot pins and the pivot axes of the fixed pivot pins are coincident with each other, and the movable jaws and fixed jaws translates along a translation axis towards and away from each other wherein the translation axis is coincident with the pivot axis of the pivot axis of each of the fixed upper jaw halves and the movable upper jaw halves.

摘要： An apparatus for attaching abutting ends of first and second coaxial pipe sections together. The apparatus includes a support frame, a fixed pipe clamping jaw having upper and lower jaw halves carried by the support frame for positioning the first pipe section in a fixed position, a movable pipe clamping jaw having upper and lower jaw halves carried by the support frame for translating movement of the second pipe section relative to the fixed clamping jaw and into aligned abutment with the first pipe section, heating means for heating adjacent pipe ends to a butt fusion temperature and a hydraulic circuit including a hydraulic pressure pump for supplying pressure to hydraulic movement means to translate the movable pipe clamping jaws towards fixed pipe clamping jaws to the join the first and second heated pipe sections together under pressure. The apparatus also includes supplemental hydraulic pressure means for supplying hydraulic pressure to the hydraulic joining means upon loss of pressure from the hydraulic pressure pump.
