Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

With reference to Fig. 1, Fig. 2; The pipe laying barge pipe conveying means structure of the utility model is; Radially be provided with twice tooth bar 7 along pipe above deck; One termination of tooth bar 7 is provided with position transducer 8 and latch 9, and two groups of gears 6 are installed on the per pass tooth bar 7, and the one group of gear 6 on the per pass tooth bar 7 is in transmission connection with running motor 11; Each gear 6 upwards is connected with an oil cylinder 5 separately; The piston rod upper end of one of them oil cylinder 5 is provided with back-up roll 1; The piston rod upper end of another oil cylinder 5 is provided with live roll 2, and this piston-rod lower end is provided with weighing transducer 10, and live roll 2 is in transmission connection with drive motor 3; Be connected with an adjustable lever 4 between two oil cylinders 5 on the per pass tooth bar 7, all oil cylinders 5 all are connected with hydraulic station 12; Position transducer 8 all is connected with PLC system 13 with weighing transducer 10, drive motor 3, running motor 11, hydraulic station 12, accepts unified control.

Back-up roll 1 also can be provided with the transmission device of oneself, promptly changes live roll 2 structures into, and this moment, two live rolls, 2 composition " V " types supported.Back-up roll 1 moves axially pipe with live roll 2 frictionallies, and the surface of two groups of rollers is wear-resisting nonmetallic composite manufacturings, and can exchange and change.

Adjustable lever 4 is in order to the distance between adjustable support roller 1 and the live roll 2, and to adapt to the conveying of different-diameter pipe, adjustable lever 4 can be the threads of lead screw nut structure, also can be the telescopic oil cylinder structure; Oil cylinder 5 makes the pipe autobalance on a plurality of conveying meanss in the middle of transporting pipe, motion steadily when pipe misalignment production line, can align pipe by human intervention adjusting oil cylinder 5; Latch 9 can be installed any position on tooth bar 7, is used for regulating the distance that moves radially, and when position transducer 8 inefficacies or fault, forces gear 6 to shut down, and avoids having an accident.

Move radially and rely on gear 6 engagement rolling on tooth bar 7 to realize, also can be by roller scrolling realization on slide rail, or realize by their combination.Two group oil cylinders 5 on the per pass tooth bar 7 are supported roller 1 and live roll 2 respectively, need not adjust height when the pipe laying production line and reach correct time, and oil cylinder 5 can remove the employing support and replace to reduce cost.
