Hydraulic and electric combined lifting roller of pipe laying ship

The utility model discloses a hydraulic and electric combined lifting roller of a pipe laying ship. The hydraulic and electric combined lifting roller comprises a driving roller and a driven roller; the driving roller is mounted on a driving roller support, and the driven roller is mounted on a driven roller support; a shaft end of the driving roller is connected with a motor reducer; the driving roller support and the driven roller support are respectively fixed to opposite corners of a base via outer hexagonal screws and are laterally symmetrical with each other; and a hydraulic cylinder used for upwardly jacking a pipe to enable the pipe to be separated from a conveying roller is mounted on the base. The hydraulic and electric combined lifting roller has the advantages that the driving roller is driven by a motor, and the roller rotates to drive the sea pipe on the roller to move back and forth; and the height of the sea pipe can be adjusted by adjusting expansion and contraction of the hydraulic cylinder,
