Abstract
The utility model relates to a large-inclination angle chain cable fairlead. The large-inclination angle chain cable fairlead is characterized in that the radial outer side of the large-inclination angle chain cable fairlead is provided with a chain jump preventing convex edge; the chain jump preventing convex edge exceeds the thickness of a transverse knob of a chain cable so that the transverse knob of the chain cable is wrapped by the side surface of the chain jump preventing convex edge and the possibility of dropping when a large-inclination angle is enlarged is reduced; a support frame positioned on the side surface of the large-inclination angle chain cable fairlead is in a dissymmetric structure and particularly comprises a long wrist plate and a short wrist plate, the long wrist plate is positioned at one side with a blunt angle as an included angle of the large-inclination angle chain cable fairlead and a supporting surface, and the short wrist plate is positioned at one side with an acute angle as the included angle of the large-inclination angle chain cable fairlead and the supporting surface. Compared with the prior art, the utility model has the characteristics of ensuring that installation and usage inclination angles can maximally reach 50 degrees, being suitable for the current standard service conditions and the super-current standard service conditions and meeting the requirement for large-inclination angle installation and usage of a ship.
Description
Technical field
The utility model relates to a kind of large inclined angle chain wheel for hawse pipe, belongs 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 non-standard large inclined angle chain wheel for hawse pipe that the utility model provides a kind of boats and ships to use has 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 utility model 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 the utlity model has are: installation and use 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 the utility model large inclined angle chain wheel for hawse pipe.
Fig. 2 is that the large inclined angle installment work of the utility model large inclined angle chain wheel for hawse pipe 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 utility model is described further.
Boats and ships large inclined angle chain wheel for hawse pipe as shown in Figure 1, that the utility model provides 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 utility model is installed and used 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 the embodiment of the utility model is specified above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also make various variations not breaking away under the utility model aim prerequisite.
Claims (4)
1. large inclined angle chain wheel for hawse pipe, it is characterized in that: the roller radial outside is provided with anti-jump chain convex edge, and side supports is that non-symmetry structure is made up of long toggle plate and short bracket.
2. large inclined angle chain wheel for hawse pipe as claimed in claim 1 is characterized in that: anti-jump chain convex edge exceeds anchor chain and laterally saves thickness, and anchor chain laterally joint is in the side coating of anti-jump chain convex edge.
