Abstract
The invention relates to a large-inclination-angle chain cable fairlead. A chain jumping convex edge is arranged at the radial outside of a roller wheel, and the chain jumping convex edge exceeds the thickness of an anchor chain lateral segment, so that the anchor chain lateral segment is wrapped by the side surface of the chain jumping convex edge and the falling probability is reduced when the inclination-angle is increased. A side surface support of the large-inclination-angle chain cable fairlead is of an asymmetric structure, and is specifically composed of a long toggle plate and a short toggle plate, wherein the long toggle plate is located at one side of the chain cable fairlead with an included angle with a supporting surface being obtuse angle, and the short toggle plate is located at one side of the chain cable fairlead with an included angle with the supporting surface being acute angle. As compared with the prior art, the large-inclination-angle chain cable fairlead provided by the invention has the characteristics that the installation and using inclination angle can achieve 50 degrees maximally; and the large-inclination-angle chain cable fairlead is suitable for using conditions of current standard and using conditions exceeding the current standard, and satisfies the large-inclination-angle installation and use requirements of shipping.
Description
Technical field
The present invention relates to a kind of large inclined angle chain wheel for hawse pipe, belong to technical field of ships.
Background technique
The industry standard of present chain wheel for hawse pipe peculiar to vessel is " chain wheel for hawse pipe " CB/T290-1995, is only applicable to maximum 24 ° mounted angle, is not suitable for the installation conditions of special boat.
Summary of the invention
The invention provides the non-standard large inclined angle chain wheel for hawse pipe that a kind of boats and ships use, solved the adoption of existing standard chain wheel for hawse pipe and can't satisfy the problem that the boats and ships large inclined angle is installed and used requirement.Current standard chain wheel for hawse pipe inclination angle is 24 degree to the maximum, after the inclination angle is excessive, can cause chain to skid off and descends because of structure problem causes durability, damages easily, and influence is normally used.
The present invention realizes that the technological scheme that goal of the invention adopts is: the roller radial outside is provided with anti-jump chain convex edge; Anti-jump chain convex edge exceeds anchor chain and laterally saves thickness; During the side that makes the horizontal joint of anchor chain be in anti-jump chain convex edge coats, the possibility that comes off when reducing the inclination angle increasing.
Large inclined angle chain wheel for hawse pipe side supports is a non-symmetry structure, specifically is made up of long toggle plate and short bracket, and long toggle plate is a side at obtuse angle at chain wheel for hawse pipe and supporting surface angle, and short bracket is a side of acute angle at chain wheel for hawse pipe and supporting surface angle.
Compared with prior art, the characteristics that have of the present invention are: install and use the inclination angle maximum can reach 50 °; Be suitable for current standard service condition and ultra current standard service condition, satisfy the boats and ships large inclined angle and install and use requirement.
Description of drawings
Fig. 1 is the working state schematic representation of large inclined angle chain wheel for hawse pipe of the present invention.
Fig. 2 is that the large inclined angle installment work of large inclined angle chain wheel for hawse pipe of the present invention is to schematic representation.
Among the figure: 1 is the roller with anti-jump chain convex edge, and 2 is bearing pin, and 3 is the straight-through type lubricating cup, and 4 is support, and 5 is lining, and 6 is keep plate, and 7 is screw, and 8 is spring washer, and 9 is long toggle plate, and 10 are short bracket.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is described further.
As shown in Figure 1, boats and ships large inclined angle chain wheel for hawse pipe provided by the invention comprises roller 1 and large inclined angle chain wheel for hawse pipe bracket institution and service organization with anti-jump chain convex edge; Large inclined angle chain wheel for hawse pipe bracket institution comprises support 4, long toggle plate 9 and short bracket 10, bearing pin 2; Lining 5, keep plate 6, screw 7; Spring washer 8 is for the service organization of chain wheel for hawse pipe work comprises straight-through type lubricating cup 3.
The roller radial outside is provided with anti-jump chain convex edge; Anti-jump chain convex edge exceeds anchor chain and laterally saves thickness, during the side that makes the horizontal joint of anchor chain be in anti-jump chain convex edge coats, and the possibility that comes off when reducing the inclination angle increasing; Anchor chain is tiled on the roller when laterally saving work, and its thickness is chain link thickness.
Large inclined angle chain wheel for hawse pipe side supports is a non-symmetry structure; Specifically form by long toggle plate and short bracket; Long toggle plate is a side at obtuse angle at chain wheel for hawse pipe and supporting surface angle, and short bracket is a side of acute angle at chain wheel for hawse pipe and supporting surface angle, and installation and use inclination angle maximum can reach 50 °; Promptly by perpendicular to maximum tiltable 50 degree of supporting surface, exceed 50 degree and anchor chain then can occur and deviate from phenomenon.
The present invention installs and uses requirement according to large inclined angle, and design anti-jump chain convex edge on the basis of current standard roller guarantees normal, safety, the reliably working of anchor chain.Design asymmetric bracket and improved the strength and stiffness that large inclined angle is installed.
Combine accompanying drawing that embodiments of the invention are specified above, but the present invention is not limited to the foregoing description, in the ken that those of ordinary skills possessed, can also makes various variations not breaking away under the aim prerequisite of the present invention.
