Abstract
Description
Technical Field
[0001] This utility model relates to the field of winch cable adjustment technology, and in particular to an adaptive adjustment device for ship winch cables. Background Technology
[0002] In marine operations, such as marine surveys, the water depth often exceeds 1,000 meters and the sea conditions are complex. The winch cable may be tight or loose during operation. In such cases, the winch cable laying device may lose its normal cable laying function, and the steel cable may be bent or broken, thus affecting the smooth progress of the operation. Therefore, ships use automatic tension adjusting winches to self-adjust the winch cable. The automatic tension adjusting winch applies an adjustable torque to the cable drum to maintain balance with the tension torque caused by the mooring cable tension. When the cable tension deviates from the set value due to changes in the ship's draft, tides, or wind, the automatic tension adjusting winch can automatically raise and lower the cable to stabilize the tension at the specified value.
[0003] Existing automatic tension adjusting winches, when self-adjusting the cable during mooring, are prone to adjustment lag due to cable tension fluctuations caused by factors such as ship loading and unloading and tides. This leads to sudden increases and decreases in tension, cable skewing and disarray, increased risk of wear and breakage, and the impact load of cable tension fluctuations can accelerate damage to the winch transmission system. Ships may drift due to unstable cable tension, affecting the safety and efficiency of ship mooring operations. Therefore, we propose a ship winch cable self-adjustment device. Utility Model Content
[0004] The main objective of this invention is to provide an adaptive adjustment device for ship winch cables. This device, through the use of hydraulic dampers A and B, along with a spring and a cable-passing mechanism, forms an elastic buffer structure for cable guidance. When the cable tension changes abruptly due to factors such as loading / unloading or tides, the telescopic rods of the hydraulic dampers extend and retract synchronously with the springs, absorbing impact energy in real time and preventing sudden increases or decreases in tension. The cable-passing mechanism at the double-headed frame A, double-headed frame B, hydraulic dampers A and B uses guide wheels to guide the cable's winding and unwinding path. The design allows the hydraulic damper and spring's buffering effect to act directly on the cable entry end, compensating for the winch's adjustment lag and solving the problem of cable skewing and layering at the winch. Furthermore, the damping characteristics of the hydraulic damper and the elastic deformation of the spring effectively buffer the impact load generated by cable tension fluctuations, reducing overload damage to the winch transmission system. At the same time, real-time stable tension control can prevent the ship from drifting due to unstable cable tension, reducing the frequency of manual intervention, improving mooring safety in unattended or severe weather conditions, and ensuring the efficiency of ship berthing operations. This effectively solves the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A ship winch cable adaptive adjustment device includes a base plate, a hydraulic damper A, a hydraulic damper B, and a rope-passing mechanism. A top plate is welded to the surface of the base plate via a bridge plate. A double-headed frame A and a double-headed frame B are symmetrically mounted on the base plate surface on one side of the bridge plate. A hydraulic damper A is mounted on the base plate surface between the double-headed frames A and B. A hydraulic damper B is mounted on the lower surface of the top plate between the hydraulic damper A and the double-headed frame B. Head plates for mounting the rope-passing mechanism are fixed at the upward rod head of the hydraulic damper A and the downward rod head of the hydraulic damper B. Springs are sleeved around the rods of the hydraulic dampers A and B behind the head plates. The rope-passing mechanism is mounted on the upper plate of the double-headed frames A and B away from the base plate. The rope-passing mechanism includes a base plate, a central support plate, and guide wheels. The central support plate is fixed to the top of the base plate, and guide wheels are rotatably mounted on the central support plate via bearings.
[0007] Furthermore, a T-shaped hole is provided through the web of the middle support plate, and a bearing is interference-fitted into the large cavity of the T-shaped hole. A support wheel shaft on one side of the guide wheel is interference-fitted between the inner ring of the bearing and the small hole of the T-shaped hole, and a threaded bolt shaft for screwing a flange nut is fixed at the end of the support wheel shaft of the guide wheel.
[0008] By adopting the above technical solution, after the outer ring of the bearing is interference-fitted into the T-shaped hole of the middle support plate, the support wheel shaft of the guide wheel interference-fits through the inner ring of the bearing, so that the threaded bolt shaft passes through the shaft body of the T-shaped hole and is screwed with a flange nut to prevent it from slipping.
[0009] Furthermore, the upper plate of the double-headed frame A and the double-headed frame B is bolted to the base plate of the rope-carrying mechanism, and the head plate surface of the hydraulic damper A and the hydraulic damper B is bolted to the base plate of the rope-carrying mechanism.
[0010] By adopting the above technical solution, the base plate of the rope-passing mechanism can be locked at the double-headed frame A and double-headed frame B with bolts, so that there is a rope-passing mechanism at the double-headed frame A and double-headed frame B to guide the winch cable through. At the head plate of hydraulic damper A and hydraulic damper B, the base plate of the rope-passing mechanism can be locked at the head plate of hydraulic damper A and hydraulic damper B with bolts, so that there is a rope-passing mechanism at the head plate of hydraulic damper A and hydraulic damper B to guide the winch cable through.
[0011] Furthermore, the substrate surface below the dual-head frame A and dual-head frame B is provided with insertion holes for mounting the insertion pins, and the insertion pins are welded to the base of the dual-head frame A and dual-head frame B. The base of the dual-head frame A and dual-head frame B is provided with mounting holes for screwing bolts between the base and the substrate.
[0012] By adopting the above technical solution, the chassis of the double-headed frame A and the double-headed frame B are positioned and installed by inserting the pins into the insertion holes of the substrate. Then, the chassis of the double-headed frame A and the double-headed frame B can be locked to the substrate with bolts.
[0013] Furthermore, the headstock is provided with recessed grooves at the hydraulic dampers A and B behind it, and a spring is fitted between the headstock and the recessed grooves of the hydraulic dampers A and B behind it.
[0014] By adopting the above technical solution, the recessed grooves of the head plate and the hydraulic dampers A and B behind it can be fitted with springs, so that when the hydraulic dampers A and B elastically extend and retract, the springs and their own damping extension rods can form a force-bearing buffer structure to provide guidance and buffering for the cable.
[0015] Furthermore, a support column is welded between the plate on the other side of the substrate away from the bridge plate and the double-headed frame A and the top plate, and the plate surface near its own edge is staggered with perforations.
[0016] By adopting the above technical solution, the substrate and the top plate are reinforced by a support weld, and bolts can pass through the perforations in the substrate to lock the substrate to the metal surface of the ship.

[0018] This invention features an adaptive adjustment device for ship winch cables. This device, through hydraulic dampers A and B, along with springs and a rope-passing mechanism, forms an elastic buffer structure for guiding the cable. When the cable tension changes abruptly due to factors such as loading / unloading or tides, the telescopic rods of the hydraulic dampers and springs extend and retract synchronously, absorbing impact energy in real time and preventing sudden increases or decreases in tension. The rope-passing mechanisms at the double-headed frame A, double-headed frame B, hydraulic dampers A and B guide the cable winding and unwinding path with guide wheels, allowing the buffering effect of the hydraulic dampers and springs to directly act on the cable entry end, compensating for the winch adjustment lag problem and solving the problem of cable skewing and disorder during winding and unwinding at the winch.
[0019] Furthermore, the damping characteristics of the hydraulic damper and the elastic deformation of the spring effectively buffer the impact load generated by the fluctuation of cable tension, reducing overload damage to the winch transmission system. At the same time, real-time stable tension control can prevent the ship from drifting due to unstable cable tension, reduce the frequency of manual intervention, improve mooring safety in unattended or severe weather conditions, and ensure the efficiency of ship berthing operations.

The rope-passing mechanism 9 is installed on the upper plate of the double-head frame A4 and double-head frame B5 away from the base plate 1. The rope-passing mechanism 9 includes a base plate 11, a middle support plate 12 and a guide wheel 15. The middle support plate 12 is fixed at the top of the base plate 11. The guide wheel 15 is rotatably mounted on the middle support plate 12 through a bearing 14.
[0026] Among them, a T-shaped hole 13 is provided through the web of the middle support plate 12, and a bearing 14 is interference-fitted in the large cavity of the T-shaped hole 13. A support wheel shaft on one side of the guide wheel 15 is interference-fitted between the inner ring of the bearing 14 and the small hole of the T-shaped hole 13, and a threaded bolt shaft for screwing on the flange nut 16 is fixed at the end of the support wheel shaft of the guide wheel 15.
[0027] By adopting the above technical solution, after the outer ring of the bearing 14 is interference-fitted into the T-shaped hole 13 of the middle support plate 12, the support wheel shaft of the guide wheel 15 is interference-fitted through the inner ring of the bearing 14, so that the threaded bolt shaft passes through the shaft body of the T-shaped hole 13 and is screwed with a flange nut 16 to prevent it from slipping.
[0028] Among them, the upper plate of the double-headed frame A4 and the double-headed frame B5 is bolted to the base plate 11 of the rope mechanism 9, and the surface of the head plate 8 of the hydraulic damper A6 and the hydraulic damper B7 is bolted to the base plate 11 of the rope mechanism 9.
[0029] By adopting the above technical solution, the base plate 11 of the rope-passing mechanism 9 can be locked at the double-headed frame A4 and double-headed frame B5 with bolts, so that the rope-passing mechanism 9 can guide the winch cable through at the double-headed frame A4 and double-headed frame B5. The base plate 11 of the rope-passing mechanism 9 can be locked at the head plate 8 of the hydraulic damper A6 and hydraulic damper B7 with bolts, so that the rope-passing mechanism 9 can guide the winch cable through at the head plate 8 of the hydraulic damper A6 and hydraulic damper B7.
[0030] Wherein, the base plate 1 below the double-headed frame A4 and the double-headed frame B5 has a socket 17 for mounting the plug 18, and the plug 18 is welded to the base of the double-headed frame A4 and the double-headed frame B5. The base of the double-headed frame A4 and the double-headed frame B5 has a mounting hole for screwing bolts between the base and the base plate 1.
[0031] By adopting the above technical solution, the chassis of the dual-head frame A4 and dual-head frame B5 are positioned and installed by inserting the pins 18 into the insertion holes 17 of the base plate 1. Then, the chassis of the dual-head frame A4 and dual-head frame B5 can be locked to the base plate 1 by means of bolts.
[0032] The head plate 8 is provided with recessed grooves at the hydraulic dampers A6 and B7 behind it, and a spring 10 is fitted between the head plate 8 and the recessed grooves of the hydraulic dampers A6 and B7 behind it.
[0033] By adopting the above technical solution, the head plate 8 and the recessed grooves of the hydraulic dampers A6 and B7 behind it can hold the spring 10, so that when the hydraulic dampers A6 and B7 elastically extend and retract, the spring 10 and its own damping extension rod can form a force buffer structure to provide guidance and buffer for the cable.
[0034] Among them, the other side of the substrate 1 away from the bridge plate 2 and the double-headed frame A4 is welded with a support column 19 between the top plate 3 and the substrate 1, and the surface of the substrate 1 near its own edge is staggered with perforations.
[0035] By adopting the above technical solution, the substrate 1 and the top plate 3 are reinforced by the support column 19, and the through hole of the substrate 1 can be used to pass through the bolt, thereby locking the substrate 1 to the metal surface of the ship.
[0036] It should be noted that this utility model is a self-adjusting device for ship winch cables. After setting the self-adjusting device for ship winch cables, the base plate 1 of the adjusting device has a through hole through which bolts can pass and be locked to the metal surface near the cable entry and exit position of the ship's automatic tension adjusting winch. Then, the double-headed frame A4 and double-headed frame B5 are inserted and positioned in the insertion hole 17 of the base plate 1 by inserting post 18. Then, the double-headed frame A4 and double-headed frame B5 are locked to the surface of the base plate 1 by bolts. Then, the surface of the base plate 1 between the double-headed frame A4 and double-headed frame B5 is locked with the perforated mounting plate of the hydraulic damper A6 by bolts. At the same time, the perforated mounting plate of the hydraulic damper B7 is locked with bolts below the top plate 3. Then, the rope passing mechanism 9 is fixed to the upper plate of the double-headed frame A4 and double-headed frame B5 by its own base plate 11 and bolts. Then, the upward rod head of the hydraulic damper A6 and the downward rod head of the hydraulic damper B7 can... With the rope-passing mechanism 9 installed, the cable of the ship's automatic tension adjusting winch can pass through the guide wheel 15 above the double-head frame B5, the guide wheel 15 below the hydraulic damper B7, the guide wheel 15 above the hydraulic damper A6, and the guide wheel 15 above the double-head frame A4 before being led outwards. When the cable needs to be tied to the mooring bollard near the berthing port for berthing and loading / unloading operations, the cable is automatically wound and unwound between the mooring bollard and the ship's automatic tension adjusting winch. During the winding and unwinding of the cable, the double-head frame A4 and double-head frame B5 guide the cable through the guide wheel 15 below the hydraulic damper B7 and above the hydraulic damper A6. During the winding and unwinding process, the hydraulic dampers B7 and A6 with springs 10 extend and retract the guide wheel 15 under the cable tension, thereby buffering the cable near the ship's automatic tension adjusting winch and providing guidance for winding and unwinding, ensuring the safety and low loss when the automatic tension adjusting winch adjusts the cable.
