[0017] The present invention will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses an operating handwheel for a marine anchor winch.

[0019] Reference Figures 1 to 3 A marine anchor winch operating handwheel includes a rod body 1 and a handwheel 2 connected to one end of the rod body 1. A connecting structure 3 is provided between the handwheel 2 and the rod body 1, and the handwheel 2 is detachably connected to the rod body 1 through the connecting structure 3. The connecting structure 3 includes a connecting pipe 31, a connecting post 32, and a connecting piece 33. The top of the connecting pipe 31 is connected to the handwheel 2, and the connecting post 32 is welded and fixed to the outer peripheral surface of the rod body 1 near the end of the handwheel 2, and the axis of the connecting post 32 is perpendicular to the axis of the rod body 1. A positioning groove 321 is opened on the outer peripheral surface of the connecting post 32 facing the connecting pipe 31. The top end of the rod body 1 passes through the connecting pipe 31, and the bottom end of the connecting pipe 31 is inserted into the positioning groove 321 and abuts against the inner wall of the positioning groove 321, thereby realizing the axial positioning between the rod body 1 and the connecting pipe 31.

[0020] Reference Figures 1 to 3 The connecting piece 33 is a U-shaped plate composed of a horizontal plate 331 and vertical plates 334 welded and fixed to both ends of the horizontal plate 331. The connecting pipe 31 passes through the horizontal plate 331, and the horizontal plate 331 can slide along the axial direction of the connecting pipe 31. In order to ensure that the connecting piece 33 can rotate synchronously with the connecting pipe 31, two limiting strips 313 are fixed on the outer circumferential surface of the connecting pipe 31. The two limiting strips 313 are arranged opposite to each other. A through hole 332 for the connecting pipe 31 to pass through is opened in the center of the horizontal plate 331, and a slot 333 adapted to the limiting strip 313 is opened on the edge of the through hole 332, so that the circumferential position between the connecting pipe 31 and the connecting piece 33 is relatively fixed.

[0021] Reference Figures 1 to 3 Two vertical plates 334 are located at both ends of the connecting column 32, and the vertical plates 334 and the connecting column 32 are connected by bolts to fix the connecting piece 33 to the connecting column 32. A positioning ring 312 is fixed on the outer circumference of the connecting pipe 31, and the bottom surface of the horizontal plate 331 abuts against the positioning ring 312. The positioning ring 312 is set to position the connecting piece 33, improving the ease of installation between the connecting piece 33 and the connecting column 32.

[0022] When the connecting pipe 31 is rotated by the handwheel 2, the connecting pipe 31 synchronously drives the connecting piece 33 to rotate. The connecting piece 33, through the connecting post 32, drives the rod body 1 to rotate, thus realizing the tightening and loosening operation of the braking device. When it is necessary to replace or maintain the handwheel 2, the bolt between the connecting piece 33 and the connecting post 32 can be loosened and removed. Then, the handwheel 2 and the connecting pipe 31 can be removed from the rod body 1. The operation is convenient, and handwheels of different diameters can be replaced to facilitate the rotation of the rod body 1 and improve the convenience of braking operation.

[0023] Reference Figure 1 , Figure 4 and Figure 5 The handwheel 2 includes a ring 21, a connecting ring 22, and a connecting rod 23. The connecting ring 22 is sleeved on the connecting pipe 31 and slidably connected to the connecting pipe 31. The ring 21 is coaxially arranged on the outside of the connecting ring 22. In this embodiment, there are two connecting rods 23, which are symmetrically arranged on both sides of the axial direction of the connecting ring 22. The two ends of each connecting rod 23 are welded and fixed to the ring 21 and the connecting ring 22, respectively. The inner wall of the central hole of the connecting ring 22 has a limiting groove 221 for the limiting strip 313 to pass through. Rotating the ring 21 can drive the connecting pipe 31 to rotate synchronously. The handwheel 2 is provided with a locking mechanism 4, and the handwheel 2 is relatively fixed to the connecting pipe 31 through the locking mechanism 4.

[0024] Reference Figure 1 , Figure 4 and Figure 5 The locking mechanism 4 includes a movable pin 43, a spring 41, and a gripping rod 42. The connecting rod 23 has a hollow interior forming a sliding cavity 231. One end of the sliding cavity 231, away from the handwheel 2, extends through to the center hole of the connecting ring 22. The movable pin 43 is located within the sliding cavity 231 and is slidably connected to the inner wall of the sliding cavity 231. A slot 232 communicating with the sliding cavity 231 is provided on the side wall of the connecting rod 23. One end of the gripping rod 42 is hinged to the side wall of the movable pin 43 through the slot 232. The inner surface of the outer circumference of the wheel ring 21... A circumferential arc-shaped groove 211 is provided on the side ring 21. The other end of the gripping rod 42 passes through the arc-shaped groove 211 and is slidably connected to the inner wall of the arc-shaped groove 211. The spring 41 is located inside the connecting rod 23 and at the end of the movable pin 43 away from the connecting tube 31. One end of the spring 41 is fixedly connected to the movable pin 43, and the other end is fixedly connected to the inner wall of the sliding cavity 231. Several insertion holes 311 for the movable pin 43 to be inserted are provided on the outer circumferential surface of the connecting tube 31. The insertion holes 311 are arranged along the axial direction of the connecting tube 31. In order to facilitate the insertion of the movable pin 43 into the insertion holes 311, the upper and lower edges of the end face of the movable pin 43 near the connecting tube 31 are chamfered.

[0025] The locking mechanism 4 is designed not only to fix the handwheel 2 to the connecting tube 31, but also to facilitate the adjustment of the axial position of the handwheel 2. When adjustment is required, the operator can grip the grip rod 42 and deflect it toward the wheel ring 21. Then, the grip rod 42 drives the movable pin 43 to disengage from the insertion hole 311. At this time, the spring 41 is in a compressed state, and the axial position of the handwheel 2 can be adjusted back and forth to adapt to the operator's working environment and work habits. After adjusting the handwheel 2 to the required position, the grip rod 42 is released, and under the action of the spring 41, it moves toward the connecting tube 31 and is inserted into the corresponding insertion hole 311, thus completing the relative fixation of the handwheel 2 and the connecting tube 31.
