[0002] The supporting device for ship cable is an important component in ship mooring system, and its core role is to provide stable support and guide for the cable, to avoid the swing or displacement between the cable and the deck due to the action of external factors such as wind and waves, water flow, so as to maintain the stability of the ship.

[0003] The existing supporting device is mostly fixed roller frame, and the water level of port wharf is frequently fluctuated due to the influence of factors such as tide and ship load, which causes the contact height between the cable and the supporting device to change constantly. In this process, if the cable is excessively drooping, it will increase the friction with the edge of the wharf; if the cable is excessively tight, it will increase the instantaneous impact force, and when the water level changes, if the supporting height of the supporting device is too high, the contact area of the cable with the roller will increase, and the friction distance will be prolonged; if the supporting is too low, the cable is easy to be scraped with the edge of the wharf or other structural members, which will all aggravate the wear and tear of the cable and shorten its service life.
