These drawings are all simplified schematic diagrams, just with the schematic way to illustrate the basic structure of the utility model, so it just shows the constitution related to the utility model.

[0019] The utility model discloses a brake braking device of a marine anchor windlass.

[0020] Refer to Figure 1 And Figure 2The application relates to a brake device of a ship anchor winch, which comprises an upper brake band 1, a lower brake band 2, a lever assembly 5 and a brake handle 6, the upper brake band 1 is hingedly connected with one end of the lower brake band 2 through a pin shaft, a tight edge pull plate 11 is fixed to the end of the upper brake band 1 away from the lower brake band 2, the tight edge pull plate 11 is fixed to an engineering ship, the end of the lower brake band 2 away from the upper brake band 1 is a tightening end, the tightening end is connected with a tightening screw 21, and the tightening screw 21 is connected with the brake handle 6 through the lever assembly 5. When braking, the brake handle 6 is rotated to drive the tightening screw 21 to move for tightening, so that the upper brake band 1 and the lower brake band 2 tightly hold a brake hub, and braking is realized.

[0021] The lever assembly 5 comprises a lever plate 51, a first rotating shaft 52 and a second rotating shaft 53, the lever plate 51 is hingedly connected with the tight edge pull plate 11 through the first rotating shaft 52, the second rotating shaft 53 is rotationally connected to one end of the lever plate 51, the end of the tightening screw 21 away from the lower brake band 2 is arranged in the second rotating shaft 53, a threaded sleeve 22 is arranged on the tightening screw 21, and the threaded sleeve 22 is located on the side of the second rotating shaft 53 away from the lower brake band 2. When the brake pad 4 is worn and thinned, the connecting position between the tightening screw 21 and the second rotating shaft 53 can be adjusted by rotating the threaded sleeve 22, the lower brake band 2 is tightened, and the braking effect of the brake device is ensured.

[0022] With reference to Figure 1 , Figure 3 and Figure 4 , the upper brake band 1 and the lower brake band 2 each comprise a steel ring 3 and a brake pad 4 connected to the inner circumferential surface of the steel ring 3; the brake pad 4 is in frictional contact with a brake hub to realize braking, and the brake pad 4 is easily worn and thinned under long-term friction braking, thereby affecting the braking function, so the brake pad 4 needs to be frequently replaced. The conventional bolt connection mode is inconvenient to replace, therefore, a plurality of connecting grooves 31 are formed on the inner circumferential surface of the steel ring 3 in the embodiment, the connecting grooves 31 are arranged along the circumferential direction of the steel ring 3, a connecting block 41 adapted to the connecting grooves 31 is integrally formed on the outer circumferential surface of the brake pad 4, and the connecting block 41 is located in the corresponding connecting groove 31. The brake pad 4 is inserted into the inner side of the steel ring 3 through transverse sliding, and the brake pad 4 is connected with the steel ring 3 through the cooperation of the connecting block 41 and the connecting groove 31, so that the brake pad 4 is convenient to install; in the same way, the brake pad 4 can be removed from the inner side of the steel ring 3 through transverse knocking.

Since friction braking is adopted, the connecting block 41 of the brake pad 4 and the connecting groove 31 of the rim 3 are subjected to shearing force, so the arrangement of the arc-shaped groove and the protruding part 411 increases the force acting area between the connecting block 41 and the connecting groove 31, reduces the shearing effect, and improves the connection stability.

[0025] With reference to Figure 1 , Figure 3 and Figure 4 , due to the friction effect during braking, metal particles are generated between the brake pad 4 and the brake hub, and the continuous friction of the metal particles between the brake pad 4 and the brake hub increases the wear effect of the brake pad 4. Therefore, in some embodiments, a gas blowing assembly 7 is arranged on one side of the upper brake band 1 and the lower brake band 2, the gas blowing assembly 7 includes a gas blowing frame 71, an arc-shaped gas pipe 72, and a plurality of gas nozzles 73 connected to the arc-shaped gas pipe 72, the gas blowing frame 71 is fixed to the outer side of the rim 3, the arc-shaped gas pipe 72 is coaxial with the rim 3, the gas outlet of the gas nozzle 73 faces the inner side wall of the brake pad 4, and the arc-shaped gas pipe 72 is connected to a gas supply device such as an air compressor through a pipeline. Therefore, the metal particles generated by the friction between the brake pad 4 and the brake hub can be removed by the gas blowing assembly 7, and the friction loss of the brake pad 4 is reduced.
