Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ship mooring ropes, in particular to a ship mooring rope anti-jumping self-centering guide wheel device. BACKGROUND

[0002] The ship mooring cable operation is a routine operation for the ship to approach and leave the wharf in normal operation, which is not only frequent but also has a certain risk. When the cable is towed to the wharf bitt, we can start to tighten the cable. Before tightening the cable, the wharf cable worker should be reminded to avoid and then the cable is collected through the cable car. A part of the cable is tightened and collected on the pile through the guide wheel. During the whole tightening process, the crew needs to operate, which is also a dangerous operation and requires the operating personnel to be highly vigilant throughout the operation. When the guide wheel is used to tighten the cable, the cable is pulled and tightened by the friction between the cable and the guide wheel. The number of turns on the guide wheel should not be too small, otherwise it is easy to slip and melt the cable. Too many turns are easy to press the cable or run off the guide wheel, so it is appropriate to wind three turns when the cable is not under heavy stress. Although the cable is wound three turns on the guide wheel, it may still press the cable or run off the guide wheel due to the lack of timely processing. When the cable is wound to the upper part of the inclined edge of the guide wheel, the worker needs to hold the cable and push it towards the guide wheel. At this time, the cable on the outside of the guide wheel is in a relaxed state, and the cable will slide down to continue to be tightened, and the whole process is repeated.

[0003] The existing manual operation mode has the following significant disadvantages: 1) high labor intensity, the crew needs to stand by the guide wheel throughout the cable collection operation and repeatedly manually push the cable, especially in the case of large tonnage of the ship and multiple mooring cables, the operating personnel need to maintain the lifting posture for a long time, which consumes a lot of physical strength, and the tightening process of a single cable often lasts for tens of minutes, which easily causes muscle strain; 2) high safety risk, during the operation, the cable is always in a high tension state, and if the cable slips, suddenly rebounds or jumps out, the crew operating at close range is easy to be hit or tripped by the cable, which poses a risk to personal safety; 3) limited operation efficiency, which cannot adapt to the trend of automation, the rhythm of manual operation is slow, and during the peak period of the ship approaching and leaving the wharf, multiple cable tightening operations require a large number of manpower to operate simultaneously, which prolongs the overall approach and departure time; 4) unable to adapt to complex and harsh conditions, in poor conditions such as night, rain, snow, strong wind and low visibility, personnel observation is difficult and standing is unstable, the risk and failure rate of manual operation increases sharply; Therefore, a ship mooring cable anti-jumping self-centering guide wheel device is proposed to solve the above problems.

[0033] Example

[0034] like Figures 1-11 As shown, a ship mooring cable anti-derailment self-centering guide wheel device includes a base 4 and a side plate 9. The base 4 is fixed to the ship's deck by welding or bolting. A motor 5 is fixedly connected to one end of the base 4. A main shaft 6 is fixedly connected to the end of the central shaft of the motor 5, and the main shaft 6 is rotatably connected to the base 4. A guide wheel 7 is fixedly connected to the outside of the main shaft 6. A cable 8 is wound around the outside of the guide wheel 7. One end of the cable 8 is fixed to the dock bollard, and the other end passes through the anti-derailment mechanism 2. With the synergistic effect of the guide wheel 7 and the anti-derailment mechanism 2, the cable 8 between the ship and the dock bollard can be gradually tightened, achieving reliable mooring of the ship. One end of the base 4 is fixedly connected to a pushing mechanism 1, a guide rail 12, and a side plate 9. An auxiliary shifting mechanism 3 is provided on one side of the guide wheel 7. A slider 11 is slidably connected to the outside of the guide rail 12. A horizontal plate 10 is fixedly connected to one end of the slider 11. An anti-jump mechanism 2 is fixedly connected to one end of the horizontal plate 10. The pushing mechanism 1 is located on one side of the anti-jump mechanism 2. When some parts of the anti-jump mechanism 2 move, the slider 11 will slide along the guide rail 12 through the horizontal plate 10. The slider 11, the guide rail 12, and the horizontal plate 10 together constitute a support and guide limiting assembly, providing stable operating constraints for the anti-jump mechanism 2 and ensuring its precise and reliable operation.

[0035] As a further improvement to the present invention, such as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the anti-jump mechanism 2 includes a connecting seat 209 fixedly connected to the horizontal plate 10. The connecting seat 209 is fixedly connected to the auxiliary shifting mechanism 3. Guide blocks 212 are slidably connected to the inner sides of both ends of the connecting seat 209. A first conveying wheel 210 is rotatably connected to the inner side of the bottom end of the connecting seat 209. A drive assembly is fixedly connected to one end of the first conveying wheel 210. A second conveying wheel 211 is rotatably connected to one end of the guide block 212. The cable 8 is threaded between the first conveying wheel 210 and the second conveying wheel 211. When the guide block 212 slides along the connecting seat 209, it can drive the second conveying wheel 211 to move synchronously, thereby adjusting the clamping force of the two wheels on the cable 8 and ensuring that the first conveying wheel 210 and the second conveying wheel 211 can stably drive the cable 8 to be conveyed. One end of the connecting seat 209 is rotatably connected to a pull rod 208, one end of the pull rod 208 is rotatably connected to a second connecting shaft 207, the other end of the second connecting shaft 207 is fixedly connected to a rotating plate 206, one end of the rotating plate 206 is rotatably connected to a first connecting shaft 204, and the first connecting shaft 204 is rotatably connected to the base 4. A torsion spring 205 is sleeved on the outside of the first connecting shaft 204, and the two ends of the torsion spring 205 abut against the rotating plate 206 and the base 4 respectively. A toggle assembly is provided on one side of the rotating plate 206. The torsion spring 205 (right-view perspective) provides a clockwise torsional force to the rotating plate 206. When the first conveyor wheel 210 and the second conveyor wheel 211 are normally conveying the cable 8, the actuating assembly does not apply a actuating action to the rotating plate 206. At this time, driven by the torque of the torsion spring 205, the rotating plate 206, through the second connecting shaft 207, the pull rod 208, and the connecting seat 209, drives the first conveyor wheel 210 and the second conveyor wheel 211 to work together, ensuring that the cable 8 between the guide wheel 7 and the connecting seat 209 remains taut. When the cable 8 is pressed and stacked on the inclined surface of the guide wheel 7, the pushing mechanism 1 is triggered and drives the lever 203 of the actuating component to move to the side of the rotating plate 206. As the main shaft 6 drives the guide wheel 7 to rotate synchronously, the lever 203 acts on the rotating plate 206, causing it to rotate around the axis of the first connecting shaft 204. The rotation of the rotating plate 206 is transmitted to the pull rod 208 through the second connecting shaft 207, which in turn pulls the connecting seat 209 to move closer to the guide wheel 7, thus actively pushing the cable 8 towards the guide wheel 7. This action will cause the cable 8 between the connecting seat 209 and the guide wheel 7 to become slack, and simultaneously cause the cable 8 on the outside of the guide wheel 7 to become slack. The originally pressed and stacked cable 8 then slides down the inclined surface of the guide wheel 7 and automatically adjusts its position along the axial direction of the guide wheel 7, finally lying flat on the outside of the guide wheel 7. This process eliminates the need for staff to continuously monitor the guide wheel 7 and manually lift and push the cable 8, effectively preventing the cable 8 from slipping off the guide wheel 7 due to untimely cable pressing. This reduces the labor intensity of the operators and significantly improves the overall efficiency and operational safety of the mooring operation. When the lever 203 rotates past the rotating plate 206 with the main shaft, the lever action on the rotating plate 206 is released; at this time, the torsional force of the torsion spring 205 drives the connecting seat 209 to reset, so that the cable 8 between the connecting seat 209 and the guide wheel 7 is restored to tension, and the first conveying wheel 210 and the second conveying wheel 211 then resume normal conveying operation of the cable 8.

[0036] By repeating the above actions, the phenomenon of cable 8 being crimped and stacked can be continuously eliminated, effectively preventing cable 8 from slipping off the guide wheel 7.

[0037] As a further improvement to the present invention, such as Figure 2 and Figure 9 As shown, the actuating assembly includes a guide shaft 202 fixedly connected to the main shaft 6. A turntable 201 is slidably connected to the main shaft 6 via the guide shaft 202. Wedge-shaped surfaces are provided around the turntable 201. A lever 203 is fixedly connected to one end of the turntable 201 near the rotating plate 206. The guide shaft 202 has a dual function: firstly, it provides guidance and limitation for the turntable 201; secondly, when the main shaft 6 rotates, it drives the turntable 201 to rotate synchronously with the main shaft 6, thereby driving the lever 203 on the turntable 201 to rotate synchronously. Four levers 203 are provided, evenly distributed along the circumference of the turntable 201.

[0038] As a further improvement to the present invention, such as Figure 3 and Figure 4 As shown, the drive assembly includes a first pulley 215 fixedly connected to the shaft of the first conveying wheel 210. A belt 216 is provided on the outer side of the first pulley 215, and a second pulley 217 is sleeved on the other end of the belt 216. The second pulley 217 is fixedly connected to the guide wheel 7. During the normal rotation of the guide wheel 7 to convey the cable 8, its rotational power is synchronously transmitted to the second pulley 217 and drives the pulley to rotate. Subsequently, the second pulley 217 drives the first pulley 215 to rotate synchronously through the belt 216, thereby driving the first conveying wheel 210 to rotate accordingly. The first conveying wheel 210 and the second conveying wheel 211 cooperate to achieve stable conveying of the cable 8. A second limiting cover 220 is provided on one side of the first pulley 215. A second fixing rod 221 is fixedly connected to one end of the second limiting cover 220, and the second fixing rod 221 is fixedly connected to the connecting seat 209. A first limiting cover 218 is provided on one side of the second pulley 217. A first fixing rod 219 is fixedly connected to the bottom end of the first limiting cover 218, and the first fixing rod 219 is fixedly connected to the side plate 9. The distance between the second limiting cover 220 and the first pulley 215 is set to 2-5mm, and the distance between the inner wall of the first limiting cover 218 and the second pulley 217 is set to 10-15cm. When the connecting seat 209 feeds the cable 8 back towards the guide wheel 7 via the first conveyor wheel 210 and the second conveyor wheel 211, the first conveyor wheel 210 will drive the first pulley 215 to move synchronously towards the guide wheel 7; at this time, the belt 216 wrapped around the outside of the first pulley 215 and the second pulley 217 will loosen, and the rotational power of the second pulley 217 will not be transmitted to the first pulley 215 through the belt 216, thereby causing the first conveyor wheel 210 and the second conveyor wheel 211 to stop actively feeding the cable 8, ensuring that the cable 8 wrapped around the outside of the guide wheel 7 can remain in a loose state; When the belt 216 is in a slack state, the second limiting cover 220 can limit the belt 216 to prevent it from disengaging from the first pulley 215, ensuring that the belt 216 is always engaged in the groove of the first pulley 215. At the same time, the first limiting cover 218 is used to accommodate the slack belt 216, and its inner wall width is reserved with a gap of 3-5mm compared with the width of the belt 216. When the connecting seat 209 is reset, the first limiting cover 218 can guide the belt 216 to quickly and accurately re-engage with the groove of the second pulley 217 through its own guiding and limiting function, avoiding the belt 216 from being misaligned and stuck at the edge of the second pulley 217.

[0039] As a further improvement to the present invention, such as Figure 6 As shown, one end of each of the two guide blocks 212 is fixedly connected to a limiting plate 214, and the limiting plate 214 is slidably connected to the connecting seat 209. A locking screw 213 is screwed to the top of the connecting seat 209, and the locking screw 213 is located at the top of the guide block 212. Under the limiting constraint of the two limiting plates 214, axial movement of the second conveying wheel 211 during rotation can be effectively prevented. When it is necessary to apply compressive force to the cable 8 through the second conveying wheel 211, the operator can screw the locking screw 213 on the inner side of the connecting seat 209; under the action of threaded transmission, the locking screw 213 will drive the guide block 212 and the second conveying wheel 211 to move downward, thereby realizing the clamping operation of the cable 8.

[0040] As a further improvement to the present invention, such as Figure 2As shown, the pushing mechanism 1 includes a fixed plate 103 fixedly connected to the base 4. A connecting rod 102 is slidably connected to the inner side of the fixed plate 103. A guide cylinder 101 is fixedly connected to one end of the connecting rod 102, and a cable 8 passes through the middle of the guide cylinder 101. A baffle 105 is fixedly connected to the other end of the connecting rod 102, and the baffle 105 is disposed on one side of the turntable 201. A first spring 104 is disposed on the outer side of the connecting rod 102, and the two ends of the first spring 104 are fixedly connected to the connecting rod 102 and the fixed plate 103 respectively. A second spring 106 is fixedly connected to one end of the turntable 201, and the other end of the second spring 106 is fixedly connected to the guide wheel 7. The specifications of the guide cylinder 101 can be customized according to the diameter of the cable 8 to ensure that the cable 8 can pass smoothly through its interior. Simultaneously, a ball bearing structure can be added to the inner wall of the guide cylinder 101 to reduce frictional loss between the cable 8 and the guide cylinder 101 during cable insertion. The guide cylinder 101 should be installed close to the inclined surface area of ​​the guide wheel 7. When the cable 8 wound around the outside of the guide wheel 7 does not exhibit any crimping or stacking, the connecting rod 102, under the tension of the first spring 104, will cause the guide cylinder 101 to conform to the surface of the guide wheel 7. Simultaneously, the connecting rod 102 synchronously drives the baffle 105 to press against the wedge-shaped surface of the turntable 201, driving the turntable 201 and the lever 203 to move away from the guide wheel 7. This measure ensures that the lever 203 will not come into contact with the rotating plate 206 during the rotation of the turntable 201, thereby preventing the connecting seat 209 from moving erroneously towards the guide wheel 7. Only when cable pressing occurs on the outside of the guide wheel 7 will the connecting seat 209 move towards the guide wheel 7, preventing the overall work efficiency from being reduced due to the connecting seat 209 doing useless work. When the cable 8 wound around the outside of the guide wheel 7 experiences a pressing and stacking phenomenon on its inclined surface (it should be noted that this pressing phenomenon only occurs on the inclined surface of the guide wheel 7), the stacked cable will exert an upward supporting force on the guide cylinder 101, driving the guide cylinder 101 to move upward; at the same time, the guide cylinder 101 drives the baffle 105 through the connecting rod 102, sliding upward from the side of the turntable 201 to the wedge-shaped surface. In this state, under the pulling force of the second spring 106, the turntable 201 drives the lever 203 to move to the side of the rotating plate 206, ensuring that when the turntable 201 rotates, the lever 203 can accurately act on the rotating plate 206 and trigger its action.

[0041] As a further improvement to the present invention, such as Figure 7 and Figure 8As shown, the auxiliary displacement mechanism 3 includes a guide seat 302 fixedly connected to the side plate 9. A movable plate 301 is slidably connected between the guide seat 302 and the side plate 9. A displacement brush 310 is rotatably connected to one end of the movable plate 301. The displacement brush 310 is surrounded by bristles made of nylon. A one-way gear 309 is fixedly connected to the outside of the rotating shaft of the displacement brush 310. The one-way gear 309, also known as a one-way clutch or overrunning clutch, is a mechanical device that allows a gear to rotate freely in one direction and lock in another direction. The rotation direction of the one-way gear 309 is clockwise (top view). A connecting beam 307 is fixedly connected to one end of the connecting seat 209. A rack 308 that matches the one-way gear 309 is fixedly connected to the other end of the connecting beam 307. The rack 308 is slidably connected to the movable plate 301. The top of the side plate 9 is fixedly connected to a first support plate 305 and a second support plate 311. One end of the first support plate 305 is fixedly connected to a toggle shaft 304. An adjustment plate 303 is slidably arranged on the outer side of the toggle shaft 304, and the adjustment plate 303 is rotatably connected to the moving plate 301. One end of the connecting beam 307 is fixedly connected to a top plate 306. One end of the second support plate 311 is fixedly connected to a third spring 312, and the other end of the third spring 312 is fixedly connected to the movable plate 301.

[0042] When the cable 8 wound around the outside of the guide wheel 7 does not exhibit any crimping or stacking on its inclined surface, the connecting seat 209 will drive the top plate 306 to press against the adjusting plate 303 via the connecting beam 307; the adjusting plate 303 will then use the actuating shaft 304 as a fulcrum to push the moving plate 301 to move away from the second support plate 311, and at the same time, the moving plate 301 will drive the displacement brush 310 to completely disengage from the cable 8 on the outside of the guide wheel 7. In this way, during the rotation of the cable 8 driven by the guide wheel 7, the normal displacement of the cable 8 along the axial direction of the guide wheel 7 will not be hindered; When the cable 8 wrapped around the outside of the guide wheel 7 experiences a pressing and stacking phenomenon in its inclined area, the connecting seat 209 will shift towards the guide wheel 7. At the same time, the connecting seat 209, through the connecting beam 307, causes the top plate 306 to separate from the adjusting plate 303, releasing the abutment and limiting effect of the top plate 306 on the adjusting plate 303. At this time, under the pulling force of the third spring 312, the moving plate 301 drives the shifting brush 310 to move towards the cable 8 on the outside of the guide wheel 7 and fits tightly against the cable 8.

[0043] During this process, the connecting seat 209 also drives the rack 308 to move synchronously along one side of the one-way gear 309 via the connecting beam 307. This drives the one-way gear 309 to move the shifting brush 310 clockwise to push the cable 8 on the outside of the guide wheel 7, thereby accelerating the crimping of the stacked cables 8 and quickly laying them flat on the outside of the guide wheel 7, improving the efficiency of handling cable crimping. After the cable crimping is completed, the shifting brush 310 will reset synchronously with the reset action of the connecting seat 209 and enter standby mode, waiting for the next work trigger.

[0044] Meanwhile, through the coordinated linkage of the pushing mechanism 1, the anti-jump mechanism 2, and the auxiliary shifting mechanism 3, this device can automatically handle the stacking and jumping problems of the outer cable 8 of the guide wheel 7. The entire system only requires a single motor 5 to complete the power transmission of the entire process, without the need for a large number of additional controllers, sensors, and other drive equipment. This mechanical linkage design has significant advantages: 1) Strong resistance to harsh environments, eliminating complex electronic control components, fundamentally reducing the interference of harsh working conditions such as high salt spray, strong vibration, and drastic temperature differences at sea on equipment operation, reducing operation interruptions caused by electronic component failures, and improving the reliability and durability of the device; 2) Low maintenance cost and simple operation, the failure rate of mechanical components is much lower than that of the electronic control system, and daily maintenance only requires lubrication and tightening of transmission components, without the need for professional electronic control maintenance technology; at the same time, it simplifies the training cost of operators and reduces the risk of human error.
