The invention belongs to the technical field of ship
engineering, and discloses a marine lifeboat side-leaning releasing device which comprises a main body, a
winch is arranged on the surface of the main body, a supporting rod is rotationally connected to the interior of the main body, and a steel cable located at one end of the supporting rod is wound on the surface of the
winch. According to the device, plugging of the liquid outlet
pipe can be cancelled through the plugging block, then lubricating oil in the
oil storage tank can enter the liquid outlet
pipe, the liquid outlet
pipe can lubricate the connecting position of the first connecting rod and the lifting hook and the connecting position of the
handle and the shell, and finally plugging of the liquid outlet pipe by the plugging block is cancelled through the driving
assembly; and furthermore, the connecting parts of the connecting rod I and the lifting hook as well as the
handle and the shell can be lubricated, so that the
frictional resistance at the connecting parts of the connecting rod I and the lifting hook as well as the
handle and the shell is reduced, the connecting rod I and the lifting hook as well as the handle and the shell are operated more flexibly and smoothly, and the overall safety of the lifeboat releasing device is improved.
