Problems solved by technology
However, the working condition of the fixed pulley used for deploying and recovering the ROV is more complicated than that of the fixed pulley for the land-use lifting device, because the ROV connected by the umbilical cable will be affected by sea currents and wind waves in the water, resulting in the disconnection between the umbilical cable and the fixed pulley. The wrapping angle changes all the time, and the angle between the umbilical cable and the longitudinal section of the fixed pulley also changes all the time, so it is very easy for the umbilical cable to jump out of the groove of the fixed pulley, and it is also easy to wear with the groove edge during use.

Abstract
The invention relates to an anti-jumping and wear-resistant fixed pulley device for a remote control submersible launching and retrieving device. The anti-jumping and wear-resistant fixed pulley device for the remote control submersible launching and retrieving device comprises a fixed pulley clamping plate, wherein a fixed pulley is connected to the fixed pulley clamping plate through a fixed pulley shaft; an umbilical cable inlet rotating shaft set is arranged at one end of the fixed pulley clamping plate; an umbilical cable outlet rotating shaft set is arranged at the other end of the fixedpulley clamping plate. The anti-jumping and wear-resistant fixed pulley device for the remote control submersible launching and retrieving device is simple in structure and convenient to use; throughclosure of the umbilical cable outlet rotating shaft set and the umbilical cable inlet rotating shaft set as well as sliding guidance and rotating wear resistance of a rotating shaft, anti-jumping and wear-resistant functions of an umbilical cable in the submersible launching and retrieving device during a marine operation are achieved, so that the safety of the marine operation of a submersibleis greatly improved.
Description
technical field [0001] The invention relates to the field of submersibles, in particular to an anti-jump and anti-abrasion fixed pulley device for deploying and recovering devices of remote-controlled submersibles. Background technique [0002] The remote-controlled submersible is an intelligent robot widely used in underwater operations. The remote-controlled submersible is connected to the deck control room or control unit on the mother ship through an umbilical cable. The deployment and recovery of the remotely controlled submersible is realized through a set of deployment and recovery devices. Usually, the deployment and recovery device is a door crane installed on the deck of the mother ship. A certain pulley is hung on the lower part of the beam of the door crane, and the umbilical cable bypasses the fixed pulley. , through the reel of the door crane to realize the take-up and release of the umbilical cable. [0003] Generally, the wrapping angle between the cable and...
