[0031] An embodiment of the present disclosure provides an anchor windlass handbrake, see Figures 1 to 4 , including a first brake steel band 1 and a second brake steel band 2. The first brake steel band 1 and the second brake steel band 2 are wrapped around the hub of the anchor windlass drum. Friction bands 3 are provided on the inner walls of the first brake steel band 1 and the second brake steel band 2. One end of the first brake steel band 1 and the second brake steel band 2 is connected through an adjusting assembly, and the other end of the first brake steel band 1 and the second brake steel band 2 is connected through a braking assembly. The braking assembly is used to adjust the retraction distance between the brake steel band and the hub of the anchor windlass drum to tighten or release the hub of the anchor windlass drum.

[0032] In an embodiment of the present disclosure, the anchor windlass handbrake is composed of a first brake steel band 1, a second brake steel band 2, a friction band 3, an adjustment assembly, and a brake assembly. Both the first brake steel band 1 and the second brake steel band 2 are arc-shaped. The first brake steel band 1 and the second brake steel band 2 are wrapped around the surface of the anchor windlass drum hub. Friction bands 3 are respectively installed on the inner surfaces of the first brake steel band 1 and the second brake steel band 2.

The other ends of the first brake steel band 1 and the second brake steel band 2 are connected through the brake assembly. After assembling the anchor windlass handbrake device externally, it is installed on the anchor windlass drum hub, then the state of the brake assembly is adjusted, and the adjusted brake assembly is fixed on the ship deck. By pulling or releasing the movable end of the second brake steel band 2 through the brake assembly, the retraction distance between the second brake steel band 2 and the anchor windlass drum hub is adjusted, so as to adjust the clamping force of the first brake steel band 1 and the second brake steel band 2 on the anchor windlass drum hub, and realize braking or releasing the anchor windlass drum hub.

[0033] Compared with the existing anchor windlass brake device, the anchor windlass handbrake adjusts the retraction distance between the second brake steel band and the anchor windlass drum hub through the brake assembly, thereby adjusting its clamping force on the anchor windlass drum hub, controlling the magnitude of the anchor windlass braking force, realizing the control of the anchor throwing speed of the anchor windlass, achieving safe and stable anchor throwing of the anchor windlass, and improving the safety of humans and machines.

[0034] In an embodiment of the present disclosure, the adjustment assembly is located on the side of the first brake steel band 1 and the second brake steel band 2 close to the direction of the anchor chain entering the water, and the brake assembly is located on the side of the first brake steel band 1 and the second brake steel band 2 away from the direction of the anchor chain entering the water.

[0035] In an embodiment of the present disclosure, see Figures 1 to 4 It also includes an anchor windlass base 5, and the brake assembly is rotatably installed at the top of the anchor windlass base 5. In this way, by rotatably installing the brake assembly through the anchor windlass base 5, it is convenient to adjust the state of the brake assembly, and by fixing the brake assembly through the anchor windlass base 5, it is convenient to use the brake assembly.

[0036] In an embodiment of the present disclosure, see Figure 1 and Figure 3, the brake assembly includes: a first connecting rod 6, one end of the first connecting rod 6 is rotatably connected to the other end of the first brake steel band 1, and the other end of the first connecting rod 6 is rotatably connected to the lower part of the connecting frame 7; a tripod 8, the first end of the tripod 8 is rotatably connected to the other end of the second brake steel band 2, and the second end of the tripod 8 is rotatably connected to the first end of the connecting frame 7; a V-shaped frame 9, the V-shaped frame 9 is arranged with its opening facing downwards, one end of the V-shaped frame 9 is rotatably connected to the second end of the connecting frame 7, and a first pin shaft 10 is rotatably arranged at the top of the V-shaped frame 9, and a second pin shaft 11 is rotatably arranged at the third end of the connecting frame 7; a second connecting rod 12, one end of the second connecting rod 12 is rotatably connected to the third end of the tripod 8, and the other end of the second connecting rod 12 is rotatably connected to the bracket of the V-shaped frame 9 close to the first brake steel band 1; a lead screw 13, a runner 19 is arranged at one end of the lead screw 13, the other end of the lead screw 13 sequentially passes through the first pin shaft 10 and the second pin shaft 11, and the lead screw 13 is threadedly connected to the first pin shaft 10 and the second pin shaft 11 respectively. Thus, through the threaded transmission between the lead screw 13 and the first pin shaft 10 and the second pin shaft 11, the movable end of the second brake steel band 2 is pulled or released, the retraction distance between the second brake steel band 2 and the hub of the windlass drum is adjusted, and the clamping force of the first brake steel band 1 and the second brake steel band 2 on the hub of the windlass drum is adjusted, so as to control the magnitude of the windlass braking force.

[0037] Optionally, referring to Figure 1 and Figure 2 , the brake assembly further includes a third connecting rod 14, one end of the third connecting rod 14 is rotatably connected to the top end of the windlass base 5, and the other end of the third connecting rod 14 is rotatably connected to the fourth end of the connecting frame 7 through a fourth pin shaft 20. Thus, the overall angle of the brake assembly can be adjusted to avoid generating additional bending moments on the hub of the windlass drum.

[0038] Optionally, referring to Figure 1 , a pedal 15 is arranged at the other end of the V-shaped frame 9. Thus, it can be realized that by manually stepping on the pedal 15, the force for rotating the runner 19 can be relieved, so as to continue rotating the runner 19, which is convenient for further controlling the magnitude of the windlass braking force.

[0039] It can be understood that when increasing the windlass braking force, manually rotate the runner 19 to drive the lead screw 13 to rotate. Through the threaded transmission between the lead screw 13 and the second pin shaft 11, the lead screw 13 moves downward. Through the threaded transmission between the lead screw 13 and the first pin shaft 10, the first pin shaft 10 is driven to move downward along the lead screw 13, so that the V-shaped frame 9 rotates downward around its connection with the connecting frame 7. The V-shaped frame 9 drives the third end of the tripod 8 to rotate downward around the second end of the tripod 8 through the second connecting rod 12, and drives the first end of the tripod 8 to rotate upward, pulling the movable end of the second brake steel band 2, so that the friction belt 3 rubs against the drum, realizing the braking of the drum.

[0040] Optionally, a limit block is provided at the other end of the lead screw 13, so that the lead screw 13 can be prevented from disengaging from the second pin shaft 11.

[0041] Optionally, anti-slip lines are evenly distributed on the surface of the runner 19, so that it is convenient for the crew to manually rotate the runner 19.

[0042] In an embodiment of the present disclosure, refer to Figure 1 and Figure 3 , the adjusting assembly includes a double-headed bolt 4, a mounting bracket 16, and a third pin shaft 17; mounting brackets 16 are respectively provided on the outer walls of one ends of the first brake steel belt 1 and the second brake steel belt 2, and third pin shafts 17 are respectively provided at one ends of the two mounting brackets 16 that are close to each other; the double-headed bolt 4 sequentially passes through the two third pin shafts 17, and both ends of the double-headed bolt 4 are respectively threadedly connected to nuts 18; a sleeve 21 is sleeved on one end of the double-headed bolt 4, and the sleeve 21 is located between the third pin shaft 17 and the nut 18. In this way, the first brake steel belt 1 and the second brake steel belt 2 can be quickly disassembled and connected; the connection distance between the first brake steel belt 1 and the second brake steel belt 2 can be adjusted.

[0043] In an example, two nuts 18 are screwed on the end of the double-headed bolt 4 where the sleeve 21 is installed. In this way, the sleeve 21 can be prevented from loosening after the first brake steel belt 1 and the second brake steel belt 2 are connected.

[0044] It can be understood that when adjusting the connection distance between the first brake steel belt 1 and the second brake steel belt 2, rotate the nut 18 at the end of the double-headed bolt 4 away from the sleeve 21. Through the threaded transmission between the nut 18 and the double-headed bolt 4, the double-headed bolt 4 moves towards the direction of the first brake steel belt 1, driving the nut 18 at the end of the double-headed bolt 4 close to the sleeve 21 to move towards the direction of the first brake steel belt 1. This nut 18 abuts against the sleeve 21, and the sleeve 21 pushes the second brake steel belt 2 close to the first brake steel belt 1, realizing the adjustment of the connection distance between the first brake steel belt 1 and the second brake steel belt 2, and realizing the tightening or release of the auxiliary brake assembly on the hub of the windlass drum with different sizes.

[0045] In the embodiment of the present disclosure, refer to Figures 1 to 4 , the working process of the windlass hand brake is briefly described as follows:

[0046] When the present disclosure is in use, first, according to the size of the windlass drum hub, the first brake steel band 1 and the second brake steel band 2 are connected through the adjusting assembly, and the connection distance between the first brake steel band 1 and the second brake steel band 2 is adjusted to complete the assembly of the windlass handbrake. The assembled windlass handbrake is installed on the windlass drum hub, the brake assembly is rotated, the angle of the brake assembly is adjusted, and the adjusted brake assembly is fixed on the ship deck through the windlass base 5. The state of the brake assembly no longer changes, and the position of the first brake steel band 1 is fixed. Then, the rotating wheel 19 is rotated to drive the lead screw 13 to rotate. Through the threaded transmission between the lead screw 13 and the second pin shaft 11, the lead screw 13 moves downward. Through the threaded transmission between the lead screw 13 and the first pin shaft 10, the first pin shaft 10 is driven to move downward along the lead screw 13, so that the V-shaped frame 9 rotates downward around its connection with the connecting frame 7. The V-shaped frame 9 drives the third end of the triangular frame 8 to rotate downward around the second end of the triangular frame 8 through the second connecting rod 12, driving the first end of the triangular frame 8 to rotate upward, thereby pulling the movable end of the second brake steel band 2 to tighten the friction belt 3. When the lowering speed of the anchor chain is too fast and the lowering speed of the anchor chain is still not within the control range after the friction belt 3 is tightened, the pedal 15 is stepped on manually to relieve the force of rotating the rotating wheel 19, so as to continue to rotate the rotating wheel 19 to further tighten the friction belt 3, realizing the control of the lowering speed of the anchor chain.

[0047] After considering the specification and practicing the utility model disclosed herein, those skilled in the art will readily conceive of other embodiments of the present disclosure.
