Embodiment Construction

[0018] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] see Figure 1-4 , heavy-duty roller fairlead, the main shaft 3 is fixed on the deck 12 of the hull by welding, a plurality of reinforcing ribs 1 are evenly arranged on the outer periphery of the bottom section of the main shaft 3 and are welded with the main shaft 3 and the reinforcing ribs 1 at the same time, the bottom plate 2 is fixed on the rib plate 1 by welding, the roller 5 is set on the main shaft 3 and forms a clearance fit, and the two thrust ball bearings 4 are arranged in the upper bearing seat 504 and the lower bearing seat 505 of the roller 5, the thrust ball bearing 4. The inner ring forms an interference fit with the main shaft 3. The pressure plate 6 is arranged at the shoulder of the main shaft 3. The round nut 7 forms a threaded connection with the external thread at the top of the main shaft 3. There is a threaded hole 701 in t...

Abstract

A heavy-duty rolling wheel cable guider is provided. A main shaft is fixed on a deck of a ship body via a welding way; a plurality of reinforcing rib plates are evenly arranged on the periphery of the bottom section of the main shaft and the main shaft and the reinforcing rib plates are welded; a base plate is fixed on the reinforcing rib plates via a welding way; a rolling wheel sleeve covers the main shaft to form a clearance fit; two thrusting ball bearings are arranged in an upper bearing seat and a lower bearing seat of a rolling wheel; a thrusting ball bearing inner ring is in interference fit with the main shaft; a press plate is mounted on shaft shoulder parts of the main shaft; a round nut is in a threaded fixed connection with an external thread of the top end of the main shaft; an arc-shaped plate is connected with the base plate; and rib plates are arranged on the external arc-shaped surface of the arc-shaped plate. By the use of the heavy-duty rolling wheel cable guider, problems of great changes of parking steel cable stress direction and size due to large water level difference of mountainous rivers and artificial reservoirs can be solved, so ship parking safety can be improved and safety of people on the ship and other articles can be guaranteed.

Description

technical field [0001] The invention relates to a cable fairlead, in particular to a heavy-duty roller cable fairlead. Background technique [0002] Inland river cleat fairleads are widely used, and they are characterized by simple structure and convenient use. The basic working principle is: the mooring steel cable on the ship changes direction through the guide rollers of the fairlead to realize the tightening and loosening of the steel cable, so that the ship can in suitable waters. But the defect of this fairlead at present is that it can only be used safely when the direction of the steel cable and the fairlead are basically horizontally stressed. There will be non-horizontal tension between the fairleads, which will easily cause the main shaft of the fairlead to deform or even break, thereby seriously affecting the berthing safety of the ship and seriously threatening the lives of people on board. [0003] Due to the influence of the natural environment such as the r...
