Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, and in particular to an anti-wear structure for a guide wheel of a tugboat shore power cable. Background Technology

[0002] When tugboats are berthed in port, they obtain electrical power by connecting to the shore power supply system to reduce fuel consumption and exhaust emissions during berthing, thereby reducing environmental pollution, ship noise, and improving the port operating environment. At the same time, it can also reduce the wear and tear on ship generators and extend the service life of the equipment. In the tugboat shore power system, the cable and guide wheel will generate continuous friction during frequent deployment and retraction. If there is a lack of anti-wear structure, the cable insulation layer is easily worn through, leading to safety hazards such as leakage or even short circuit. At the same time, the guide wheel will also be affected by wear, which will affect the rotation accuracy and service life.

[0003] Existing guide wheel anti-wear structures are mostly made of a single steel material, with the wheel body integrally molded from hard nylon or polyurethane material and annular grooves machined on the surface to fit the outer diameter of the cable. Such guide wheels have poor adaptability to cables of different diameters, and the entire guide wheel assembly needs to be replaced when changing cable specifications, resulting in high operation and maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an anti-wear structure for a tugboat shore power cable guide wheel, aiming to improve the poor adaptability of existing guide wheels to cables of different diameters.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-wear structure for a guide wheel of a tugboat shore power cable, comprising a cable body, a buffer wheel attached to the surface of the cable body, a connecting arm fixedly connected to the surface of the buffer wheel, a first hollow connecting post rotatably connected to the bottom end of the connecting arm, a sliding groove slidably connected to the surface of the connecting arm, a fixing ring fixedly connected to the rear side of the first hollow connecting post, a support ring fixedly connected to the rear side of the fixing ring, a fixing base fixedly connected to the bottom of the fixing ring, a connecting ring rotatably connected to the front side of the fixing ring, and a transmission mechanism provided at the top of the connecting ring.

[0006] Preferably, the transmission mechanism includes a perforated protrusion, which is fixedly connected to a connecting ring. A first connecting block is rotatably connected to the inner wall of the perforated protrusion. A stud is threadedly connected to the inner wall of the first connecting block. A second connecting block is rotatably connected to the right side of the stud. The rear side of the perforated protrusion is in contact with the fixed ring.

[0007] Preferably, a second hollow connecting post is rotatably connected to the rear side of the second connecting block, and the second hollow connecting post is fixedly connected to the fixing ring.

[0008] Preferably, the connecting ring has a connecting hole on its surface, and connecting posts are fixedly connected to both the front and rear sides of the sliding groove, with the surface of the connecting post rotatably connected to the connecting hole.

[0009] Preferably, the surface of the connecting ring is provided with an arc-shaped groove, which is used to accommodate the connecting arm and the buffer wheel.

[0010] Preferably, a micro motor is provided on the right side of the fixing ring, and the micro motor is used to realize the automatic tensioning of the transmission mechanism.

[0011] Preferably, the bottom of the support ring is fixedly connected to the top surface of the fixed base, and the fixed base has a fixing hole on its surface.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, the connecting ring is rotated by the perforated protrusion at the top of the connecting ring, which causes the connecting arm to change angle together. This causes the buffer wheel at the top of the connecting arm to move closer to the center point of the connecting ring to fix the cable body. The buffer wheel achieves a good anti-wear effect for the guide wheel, and at the same time, the guide wheel can fix cables of different specifications.

[0014] In this invention, by installing a sensor inside the support ring and a micro motor on the right side of the stud, the tension can be adjusted in real time based on sensor feedback. The pressure of the buffer wheel on the cable is automatically adjusted through the combined action of the first connecting block, the second connecting block and the stud, thereby reducing the impact and wear during cable winding and unwinding.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-2 The present invention provides an embodiment of an anti-wear structure for a guide wheel of a tugboat shore power cable, comprising a cable body 1, a buffer wheel 3 attached to the surface of the cable body 1, a connecting arm 4 fixedly connected to the surface of the buffer wheel 3, a first hollow connecting post 8 rotatably connected to the bottom end of the connecting arm 4, a sliding groove 5 slidably connected to the surface of the connecting arm 4, a fixing ring 6 fixedly connected to the rear side of the first hollow connecting post 8, a support ring 7 fixedly connected to the rear side of the fixing ring 6, a fixing base 11 fixedly connected to the bottom of the fixing ring 6, a connecting ring 2 rotatably connected to the front side of the fixing ring 6, and a transmission mechanism provided at the top of the connecting ring 2;

[0023] The buffer wheel 3, which is attached to the surface of the cable body 1, is made of a highly elastic composite material. Its curved profile can achieve the maximum area of ​​flexible contact with the cable body 1 of different specifications, effectively dispersing contact stress. At the same time, by setting anti-slip texture on the surface of the buffer wheel 3, it can prevent the cable from sliding and causing friction damage. Through the combined action of the connecting arm 4, the slide groove 5 and the connecting ring 2, the pressure of the buffer wheel 3 on the cable body 1 can be adjusted according to the actual working conditions, avoiding the problem of cable outer sheath wear caused by excessive pressure or guide failure caused by insufficient pressure in traditional guide wheels.

[0024] Reference Figure 3 The transmission mechanism includes a perforated protrusion 13, which is fixedly connected to the connecting ring 2. A first connecting block 12 is rotatably connected to the inner wall of the perforated protrusion 13. A stud 16 is threadedly connected to the inner wall of the first connecting block 12. A second connecting block 14 is rotatably connected to the right side of the stud 16. The rear side of the perforated protrusion 13 is in contact with the fixed ring 6.

[0025] The perforated protrusion 13 is connected to the connecting ring 2 through a dovetail groove structure to ensure that there will be no loosening during frequent adjustments. The transmission mechanism adjusts the angle of the connecting ring 2 by rotating the stud 16, which in turn drives the buffer wheel 3 to adjust the pressure on the cable body 1, giving the guide wheel the advantages of fast response speed and low maintenance cost.

[0026] Reference Figure 3 The second hollow connecting column 15 is rotatably connected to the rear side of the second connecting block 14. The second hollow connecting column 15 is fixedly connected to the fixed ring 6. The second hollow connecting column 15 can withstand both radial and axial forces at the same time, ensuring the stability of the stud 16 during transmission. The fixed connection between the second hollow connecting column 15 and the fixed ring 6 is achieved by bolt fastening to ensure connection rigidity.

[0027] Reference Figure 3 The connecting ring 2 has a connecting hole 9 on its surface. Connecting posts 20 are fixedly connected to both the front and rear sides of the sliding groove 5. The surface of the connecting post 20 is rotatably connected to the connecting hole 9. The connecting post 20 is filled with energy-absorbing foam material, which can effectively absorb energy when subjected to impact loads and protect the connecting structure from damage. The surface of the connecting post 20 is treated with micro-arc oxidation to form a ceramic oxide film, which significantly improves the corrosion resistance and is especially suitable for marine environments with high salt spray.

[0028] Reference Figure 3 The connecting ring 2 has an arc-shaped groove 10 on its surface. The arc-shaped groove 10 is used to accommodate the connecting arm 4 and the buffer wheel 3. The radius of curvature of the arc-shaped groove 10 on the surface of the connecting ring 2 is dynamically set according to the movement trajectory of the buffer wheel 3, which can ensure that the connecting arm 4 can move smoothly throughout the entire adjustment range. The surface of the arc-shaped groove 10 is coated with a nickel-phosphorus alloy, which can reduce wear and energy consumption.

[0029] Reference Figure 4 A micro motor 18 is provided on the right side of the fixing ring 6. The micro motor 18 is used to realize the automatic tensioning of the transmission mechanism. The micro motor 18 is a waterproof brushless DC motor, which can resist the long-term corrosion of seawater salt spray. The motor output shaft achieves the transmission effect by rigidly connecting with the right end of the stud 16. A shock-absorbing rubber pad is provided between the mounting base of the micro motor 18 and the fixing ring 6, which can effectively isolate the vibration generated during motor operation and avoid affecting the surrounding precision components.

[0030] Reference Figure 4The bottom of the support ring 7 is fixedly connected to the top surface of the fixed base 11. The fixed base 11 has a fixing hole 19 on its surface. The fixed connection between the bottom of the support ring 7 and the fixed base 11 adopts a flange-type rigid connection structure. The bottom of the support ring 7 and the top of the fixed base 11 are matched. A sealing gasket is set between the mating surfaces to prevent seawater from seeping into the connection gap. The contact surface between the bottom flange of the support ring 7 and the fixed base 11 is sandblasted to increase the friction coefficient and improve the shear resistance of the connection, which is especially suitable for the turbulence and vibration conditions when the ship is on the sea surface.

[0031] Reference Figure 2 The support ring 7 is equipped with a sensor, and the inner wall of the support ring 7 has a rotating groove. The surface of the buffer wheel 3 is attached to a small diameter cable 17. When the surface of the buffer wheel 3 is attached to the small diameter cable 17, the sensor monitors the change in cable tension in real time, and the micro motor 18 drives the transmission mechanism to adjust the tension of the buffer wheel 3 so that the pressure of the buffer wheel 3 on the small diameter cable 17 is kept within the optimal range.

[0032] Working principle: Since the first connecting block 12 can rotate on the perforated protrusion 13 and the second connecting block 14 can rotate on the second hollow connecting post 15, when the stud 16 is rotated, the first connecting block 12 can move to the left, thereby causing the perforated protrusion 13 to rotate. Since the connecting arms 4 are all fixed to the connecting ring 2 through the sliding groove 5, and the outer sides of the connecting arms 4 are all fixed to the fixing ring 6 through the first hollow connecting post 8, when the perforated protrusion 13 at the top of the connecting ring 2 causes the connecting arm 4 to rotate, the connecting arm 4 can change angle together, so that the buffer wheel 3 at the top of the connecting arm 4 moves closer to the center point of the connecting ring 2 to achieve the fixing effect.

[0033] To address the wear problem caused by uneven tension during cable winding and unwinding, a sensor is installed inside the support ring 7, and a micro motor 18 is installed on the right side of the stud 16. This allows for real-time tension adjustment based on sensor feedback, automatically adjusting the pressure of the buffer wheel 3 on the cable, thereby reducing impact wear during cable winding and unwinding.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
