Claim Text:
1. An apparatus for assembling a positive seal coupling and a pipe, the apparatus comprising: a frame; a stationary block assembly attached to the frame and having coupling gripping doors controlled by coupling gripping doors cylinders a traveling block assembly slidably attached to the frame and having pipe gripping doors; two hydraulic ram cylinders attached to the frame and having ram cylinder rods attached to the traveling block assembly so that the hydraulic ram cylinders can move the traveling block assembly toward the stationary block assembly; the coupling gripping doors axially aligned with the pipe gripping doors so that when the hydraulic ram cylinders move the traveling block assembly toward the stationary block assembly, a pipe held by the pipe gripping doors is inserted into a coupling held by the coupling gripping doors; at least one pipe lift vee roller controlled by at least one pipe lift cylinder, and installed to at least one side of the stationary block assembly and the travelling block assembly; at least one pipe guide vee roller controlled by at least one pipe guide cylinder, and installed between the stationary block assembly and the travelling block assembly; pressure gauges in communication with the coupling door cylinders, the pipe door cylinders, the at least one pipe lift cylinder, and the at least one pipe guide cylinder, to sense pressure therein; pressure transducers in communication with the coupling door cylinders and the pipe gripping door cylinders to sense pressure therein; pressure transducers in communication with the hydraulic ram cylinders to sense a pressure difference therebetween; and a differential pressure gauge in communication with the hydraulic ram cylinders to sense the pressure difference therebetween.
