Description

Technical Field

[0001] This utility model belongs to the field of ship component technology, specifically relating to a marine positioning anchor cable guide roller cover. Background Technology

[0002] Marine mooring winches must maintain a sufficiently large distance from the positioning anchor; otherwise, the cable will become tangled on the winch shaft, making it difficult to freely retrieve and deploy the positioning anchor. At long distances, the cable may be obstructed by cabins and equipment, requiring guide rollers to bend through the obstruction points. However, the cable is prone to deviating when passing through the rollers. Therefore, a marine positioning anchor cable guide roller cover was invented. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model proposes a marine positioning anchor cable guide roller cover, which has a simple structure, is easy to operate, and prevents the cable from easily deviating when turning through the guide roller.

[0004] The technical solution of this utility model to solve the above technical problems is as follows: A marine positioning anchor cable guide roller cover is provided, including a seat plate, an annular cover plate, a ring plate, and fixing bolts. The seat plate is adapted to the size of the roller seat of the guide roller. One end of the ring plate is fixedly connected to the edge of the seat plate, and the other end of the ring plate is fixedly connected to the edge of the annular cover plate. The three together form a mushroom-shaped main structure. The ring plate has a cable inlet and outlet for the anchor cable to enter and exit. Abrasion-resistant material is fixedly attached to the inner side wall of the cable inlet and outlet. The seat plate has bolt holes adapted to the fixing bolts. The fixing bolts pass through the bolt holes to detachably and fix the seat plate to the roller seat.

[0005] The further defined technical solution of this utility model is as follows: Preferably, the width of the cable inlet / outlet is adapted to the diameter of the anchor cable, and the edge of the inlet / outlet is set as a rounded transition structure.

[0006] Preferably, the bolt holes are evenly distributed along the circumference of the seat plate, and the number of bolt holes is not less than 3. Each fixing bolt passes through the corresponding bolt hole and is screwed into the threaded hole on the roller seat one by one.

[0007] Preferably, abrasion-resistant material is fixedly attached to the inner surface of the annular cover plate and the ring plate, and the abrasion-resistant material is connected to the ring plate and the annular cover plate by adhesive bonding or bolt fastening.

[0008] Preferably, the annular cover plate, the ring plate, and the seat plate are integrally formed structures with no splicing gaps between them, and the abrasion-resistant material is fixed to the inner wall of the cable inlet and outlet by embedded installation.

[0009] The beneficial effects of this utility model are as follows: This utility model has a simple structure and is easy to operate. It avoids the cable from easily deviating when turning at the guide roller. At the same time, the mushroom-shaped main structure formed by the seat plate, the annular cover plate and the ring plate, together with the cable inlet and outlet set on the ring plate, provides a fixed entry and exit channel and trajectory constraint for the anchor cable. It can force the anchor cable to roll along the surface of the guide roller, effectively avoiding the problem of anchor cable deviation caused by uneven force and angle changes in traditional uncovered structures. In addition, the abrasion-resistant material on the inner side of the cable inlet and outlet can reduce the frictional wear between the anchor cable and the metal parts, which not only ensures the smooth movement of the anchor cable within the limited trajectory, but also reduces the risk of anchor cable breakage due to friction, further improving the stability and safety of anchor cable deployment and retrieval during ship mooring operations.

[0010] This invention provides semi-enclosed protection for the guide rollers, preventing external impurities from entering the roller's operating area and avoiding direct collisions between the anchor cable and the rollers during movement, thus reducing roller wear and the probability of failure. Furthermore, the abrasion-resistant material directly reduces contact wear between the anchor cable and the ring plate and annular cover plate, slowing down the aging of the anchor cable. Through bidirectional protection of both the anchor cable and the guide rollers, the service life is significantly extended, reducing equipment maintenance and replacement costs. Simultaneously, this device effectively shields the lubricating oil used during the guide roller's operation, preventing it from splashing or leaking into the external environment due to roller rotation. This avoids contamination of the roller itself and also prevents contamination of the ship's deck, cabin equipment, and surrounding waters, meeting the green and environmentally friendly operational requirements of the shipping industry and reducing subsequent environmental cleaning workload and costs. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation Example 1

[0012] This embodiment provides a guide roller cover for a marine positioning anchor cable, such as Figure 1 As shown, the assembly includes a seat plate 1, an annular cover plate 2, a ring plate 3, and fixing bolts 4. The seat plate 1 is sized to match the roller seat of the guide roller. One end of the ring plate 3 is fixedly connected to the edge of the seat plate 1, and the other end of the ring plate 3 is fixedly connected to the edge of the annular cover plate 2. The annular cover plate, the ring plate, and the seat plate are integrally formed without any seams between them, and together they enclose a mushroom-shaped main structure. The ring plate has a cable inlet / outlet 5 for the anchor cable to enter and exit. The width of the cable inlet / outlet is matched with the diameter of the anchor cable, and the edge of the inlet / outlet is set as a rounded transition structure. Abrasion-resistant material 6 is embedded in the inner wall of the cable inlet / outlet. The seat plate has bolt holes that match the fixing bolts. The bolt holes are evenly distributed along the circumference of the seat plate, and the number of bolt holes is not less than 3. Each fixing bolt passes through the corresponding bolt hole and is screwed into the threaded hole on the roller seat one by one for disassembly and fixation. Abrasion-resistant material is fixedly attached to the inner side of the annular cover plate and the ring plate. The abrasion-resistant material is connected to the ring plate and the annular cover plate by adhesive bonding or bolt fastening.

[0013] This embodiment features a simple structure and convenient operation, preventing the anchor cable from easily deviating when turning at the guide roller. The mushroom-shaped main structure formed by the seat plate, annular cover plate, and ring plate, along with the cable inlet / outlet on the ring plate, provides a fixed entry / exit channel and trajectory constraint for the anchor cable. This forces the anchor cable to roll along the guide roller surface, effectively avoiding the deviation problem caused by uneven force and angle changes in traditional uncovered structures. Furthermore, the abrasion-resistant material inside the cable inlet / outlet reduces frictional wear between the anchor cable and metal components, ensuring smooth movement of the anchor cable within the defined trajectory and reducing the risk of breakage due to friction. This further enhances the stability and safety of anchor cable deployment and retrieval during ship mooring operations.

[0014] This embodiment provides semi-enclosed protection for the guide rollers, preventing external impurities from entering the roller's operating area and avoiding direct collisions between the anchor cable and the rollers during movement, thus reducing roller wear and the probability of failure. Furthermore, the abrasion-resistant material directly reduces contact wear between the anchor cable and the ring plate and annular cover plate, slowing down the aging of the anchor cable. Through bidirectional protection of both the anchor cable and the guide rollers, the service life is significantly extended, reducing equipment maintenance and replacement costs. Simultaneously, this device effectively shields the lubricating oil used during the guide roller's operation, preventing it from splashing or leaking into the external environment due to roller rotation. This avoids contamination of the roller itself and also prevents contamination of the ship's deck, cabin equipment, and surrounding waters, meeting the green and environmentally friendly operational requirements of the shipping industry and reducing subsequent environmental cleaning workload and costs.

[0015] In addition to the above embodiments, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
