Abstract
The utility model provides a ship fairlead which belongs to the mechanical technical field and aims to solve the problem of inflexible rotation of the existing fairlead. The ship fairlead comprises a base, a main shaft and a pulley, wherein the main shaft is arranged above the base; the pulley is sheathed outside the main shaft; a bushing is arranged between the pulley and the main shaft; a positioning structure which is used for preventing the pulley from falling is arranged on the top end of the main shaft; a bearing is arranged between the pulley and the main shaft and sheathed on the bushing; and the outer ring of the bearing is fixedly connected with the pulley. The ship fairlead has the advantages of flexible rotation, little friction and the like.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of fairlead of boats and ships.
Background technology
A kind of special purpose parts that mooring was used when the fairlead of guiding mooring cable was the boats and ships stop, known fairlead is that the vertical bow tail that is installed in of fairlead seat is hugged the deck near the position of topside, hawser is first by fairlead during mooring, and then be fixed on the bollard or hinge cable machine on.For example, Chinese patent discloses a kind of fairlead that adopts solid drawn pipe compacting [Granted publication number be: CN 201694360 U], it comprises roller shaft, roller body and cover plate, roller body is set on the roller shaft, set lining between roller body shaft hole inner wall and the roller shaft outer wall, the roller shaft top is fixed with nut, and cover plate is fixedly connected on the roller body top.Roller body comprises roller, roller mount.It has easy to manufacture, can guarantee that the precision of fairlead and intensity meet standard-required, the advantage such as increase the service life.
But this fairlead exist rotate dumb, with the friction force of hawser greatly, often boats and ships hawser holding capacity when going to dock increases, hawser is easily broken, safety is not high.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of fairlead that rotates the boats and ships flexible, that friction force is little.
The purpose of this utility model can realize by following technical proposal:
The fairlead of these boats and ships, comprise base, be located at the main shaft of base top and be set in the pulley in this main shaft outside, has lining between described pulley and the main shaft, has the location structure that anti-limited slip wheel comes off on the top of described main shaft, it is characterized in that, be provided with bearing between described pulley and the main shaft, described bearing carrier ring is located on the above-mentioned lining, and the outer ring of described bearing and described pulley are connected.
Between main shaft and pulley, be provided with bearing, make the rotation of pulley more flexible, thereby reduce the friction force between hawser and the pulley.
In the fairlead of above-mentioned boats and ships, described bearing is 1-4.
In the fairlead of above-mentioned boats and ships, described bearing is 2.
In the fairlead of above-mentioned boats and ships, described location structure is the nut that is set on the main shaft.
In the fairlead of above-mentioned boats and ships, the top of described pulley is provided be used to preventing that dust from entering into the cover plate of pulley inside.Be provided with cover plate on pulley top, can prevent that dust etc. from entering into pulley inside, effectively prolonged the service life of pulley.
Compared with prior art, the fairlead of these boats and ships has the following advantages:
Between main shaft and pulley, be provided with bearing, make the rotation of pulley more flexible, thereby reduce the friction force between hawser and the pulley; Be provided with cover plate on pulley top, can prevent that dust etc. from entering into pulley inside, effectively prolonged the service life of pulley.
Description of drawings
Fig. 1 is the structural representation of the fairlead of these boats and ships.
Among the figure, 1, base; 2, main shaft; 3, pulley; 4, lining; 5, location structure; 6, bearing; 7, cover plate.
The specific embodiment
Below be specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1, the fairlead of these boats and ships, comprise base 1, be located at the main shaft 2 of base 1 top and be set in the pulley 3 in these main shaft 2 outsides, has lining 4 between pulley 3 and the main shaft 2, has the location structure 5 that anti-limited slip wheel 3 comes off on the top of main shaft 2, be provided with bearing 6 between pulley 3 and the main shaft 2, bearing 6 is set on the above-mentioned lining 4, and the outer ring of described bearing 6 and described pulley 3 are connected.In the present embodiment, between main shaft 2 and pulley 3, be provided with bearing 6, make the rotation of pulley 3 more flexible, thereby reduce the friction force between hawser and the pulley 3.
In use, bearing 6 is 1-4.In the present embodiment, this bearing 6 is 2.
As shown in Figure 1, location structure 5 is for being set in the nut on the main shaft 2, and the top of pulley 3 is provided be used to preventing that dust from entering into the cover plate 7 of pulley 3 inside, can prevent that dust etc. from entering into pulley 3 inside, effectively prolonged the service life of pulley 3.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used 1, base; 2, main shaft; 3, pulley; 4, lining; 5, location structure; 6, bearing; 7, the term such as cover plate, but do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
