Specific embodiments

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0024] In the present utility model, without contrary description, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for ease of understanding and description, "left, right" are usually in the left and right shown in the drawings; "inner, outer" refer to the inner and outer relative to the contours of the respective components, but the above orientation terms are not used to limit the present utility model.

[0025] Please refer to Figures 1-6 , the present utility model provides the following technical solutions:

[0026] A marine safety anchor winch, including a base 1, a motor 2 is installed on the base 1, a gearbox 3 is connected to the output shaft of the motor 2, the output ends of the gearbox 3 extend to both sides of the gearbox 3, one side of the output end of the gearbox 3 is connected to a reel 4, a reciprocating movement mechanism 7 is jointly installed on the other side of the output end of the gearbox 3 and the other side of the reel 4, the output end of the reciprocating movement mechanism 7 is connected to a fairlead 6, and the reciprocating movement mechanism 7 drives the fairlead 6 to reciprocate axially along the reel 4, so as to traction the anchor chain to move axially along the reel 4 while winding and unwinding, preventing the anchor chain from knotting.

[0027] The reciprocating mechanism 7 includes two power devices 71 and two clutch devices 72. The two power devices 71 are respectively connected to the right connecting end of the output end of the gear box 3 and the left end of the reel 4. The two clutch devices 72 are respectively arranged corresponding to the two power devices 71. A chain 74 is commonly installed on the two power devices 71. The two ends of the chain 74 are respectively connected to the two ends of the fairlead 6.

[0028] When the motor 2 is started, the right connection end of the output end of the gear box 3 and the reel 4 have the same rotation speed, that is, the two power devices 71 can always maintain the same rotation speed;

[0029] When the fairlead 6 is at the leftmost end of the reel 4, the clutch device 72 at the left end connects the chain 74 to the power device 71 at the left end, and the clutch device 72 at the right end disconnects the chain 74 from the power device 71 at the right end. At this time, the chain 74 is controlled by the power device 71 at the left end to drive the fairlead 6 to move to the right side.

[0030] When the fairlead 6 moves to the rightmost end of the reel 4, the above-mentioned action is opposite, the clutch device 72 at the right end connects the chain 74 with the clutch device 71 at the right end, and the clutch device 72 at the left end disconnects the chain 74 from the power device 71 at the left end. At this time, the chain 74 is controlled by the power device 71 at the right end to drive the fairlead 6 to move to the left side.

[0031] The above actions are repeated continuously, so that the anchor chain can be pulled to move on the reel 4 during the winding and unwinding process to prevent the anchor chain from getting tangled.

[0032] The power device 71 includes a driving bevel gear 711, which is connected to the output shaft of the gear box 3 or the reel 4 respectively, and a driven bevel gear 712 is meshed on the driving bevel gear 711. A transmission shaft 713 is installed on the central axis of the driven bevel gear 712, and one end of the transmission shaft 713 points to the clutch device 72 and is provided with a spline;

[0033] The power devices 71 on both sides are symmetrically arranged so that the rotation directions of the two transmission shafts 713 are opposite, so that the fairlead 6 can be driven to move in different directions when different power devices 71 are connected;

[0034] The power device 71 adopts a gear transmission structure, which can withstand greater impact and vibration, thereby extending the service life of the entire device;

[0035] The clutch device 72 includes a hydraulic rod 721, which is installed on the base 1. The output shaft of the hydraulic rod 721 points to the transmission shaft 713 and is coaxially arranged with the transmission shaft 713. A transmission gear 722 is rotatably connected to the output shaft of the hydraulic rod 721. The transmission gear 722 is provided with a spline at one end facing the transmission shaft 713 and can be movably engaged with the transmission shaft 713.

[0036] A slide plate 73 is fixed on the base 1, and the slide plate 73 is arranged in the circle formed by the chain 74. A track 731 is provided on the slide plate 73, and the fairlead 6 slides in the track 731, so as to limit the fairlead 6 in the front and rear directions and the up and down directions, thereby reducing the impact of the anchor chain on the fairlead 6 and the chain 74 when the anchor chain shakes. Travel switches 723 are installed at both ends of the track 731, and the two travel switches 723 jointly control the two clutch devices 72;

[0037] When the fairing 6 moves to contact the left-side travel switch 723, the left-side hydraulic rod 721 is controlled to push the corresponding transmission gear 722 to connect with the power unit 71, and at the same time, the right-side hydraulic rod 721 is controlled to pull the corresponding transmission gear 722 to separate from the power unit 71; when the fairing 6 moves to the right-side travel switch 723, the action is opposite to the above, thereby realizing the reciprocating movement of the fairing 6.

[0038] The fairlead 6 includes a mounting block 61, which is connected to the output end of the reciprocating mechanism 7. Two rollers 63 are rotatably mounted on the side of the mounting block 61 away from the reel 4. The two rollers 63 are arranged at intervals. A guide hole 62 is opened through the mounting block 61. The guide hole 62 is arranged perpendicular to the axis of the reel 4. The guide hole 62 is arranged in the middle of the two rollers 63 and is tangent to the wheel edges of the two rollers 63. Slide blocks 64 are arranged on the two corresponding side surfaces of the mounting block 61. The slide blocks 64 are slidably connected to the reciprocating mechanism 7. The shaking of the anchor chain during retraction and release is buffered through the two rollers 63, while the friction on the hole end of the guide hole 62 is reduced, thereby reducing the wear of the fairlead 6.

[0039] Specifically, two rollers 63 are provided on the side of the fairlead 6 away from the reel 4. The anchor chain passes through the gap between the two rollers 63, then passes through the guide hole 62, and finally connects to the reel 4. The circular structure of the two rollers 63 has a certain guiding effect on the anchor chain, and the rollers 63 rotate during the process of retracting and releasing the anchor chain, which reduces the friction of the anchor chain on the fairlead 6 and prolongs the service life of the fairlead 6.

[0040] The power device 71 of the reciprocating mechanism 7 adopts a gear structure, which can withstand a larger torque than a threaded structure and is not easily damaged.
