A height-adjustable claw roller fairlead

Abstract

The invention relates to a pedestal roller with the height adjusted. The pedestal roller comprises a roller fairleader, a movable base, a rotating shaft and a fixed base, and a roller fairleader hinge pin is arranged at the lower end of the roller fairleader; the movable base comprises a top plate, a skirt side plate, a pedestal and a connecting plate, and the rotating shaft is fixedly connected to the lower end of the connecting plate; a through hole is formed in the lower portion of the rotating shaft, and the fixed base comprises a base top plate, a panel and a rotating bearing seat; wrist plates are fixedly connected between the rotating bearing seat and the panel, and two fixed grooves are formed in the rotating bearing seat in the axial direction; a limiting groove is formed in the panel, and the rotating shaft is in threaded connection with the rotating bearing seat; locking round steel is inserted between the rotating shaft and the rotating bearing seat; and a round ring is fixedly arranged at one end of the locking round steel, and the locking round steel penetrates the limiting groove to be inserted in the fixed grooves and the through hole. Mooring ropes meeting the different height requirements can be moored, and the happening of rope skipping accidents is avoided.

Description

technical field [0001] The invention relates to a claw roller fairlead, in particular to a claw roller fairlead capable of adjusting the height of the cable roller. Background technique [0002] When mooring on a ship, the main way to change the direction of the cable is to rely on the roller fairlead. Our current technology usually uses the standard CB / T 436-2000 claw single-roller fairlead, and the fairlead roller is installed on a fixed base. , whose height position is fixed. The height of the base of the roller fairlead determines the installation position according to the height of the cable, try to make the cable pass through the center part of the roller fairlead to ensure the smooth passage of the cable. But on a ship, a roller fairlead often needs to undertake the task of changing the direction of multiple cables, and the height of the roller fairlead required by each cable is different. In some cases, the roller fairlead required by multiple cables The height dif...

Problems solved by technology

But on a ship, a roller fairlead often needs to undertake the task of changing the direction of multiple cables, and the height of the roller fairlead required by each cable is different. In some cases, the roller fairlead required by multiple cables The height difference of the cable is large, which exceeds the height range of the rollers that the roller fairlead can moor. However, the height of the base of the fairlead is fixed, and the height requirements of each cable cannot be taken into account at the same time, and the cable may jump out The situation of the roller fairlead leads to the breakage of the cable, damage to the equipment, and even accidents that hurt people
