Description

Technical Field

[0001] This application relates to the field of windlasses, and more particularly to a monitoring device for an anchor and windlass combination machine. Background Art

[0002] A windlass is a large deck machinery on a ship, used for retrieving and paying out the anchor and anchor chain. The windlass is usually installed on the main deck at the bow and stern of the ship, and is used when the ship anchors, drops the anchor and moors. When the windlass retrieves the anchor, the power mechanism cooperates with the transmission structure to drive the anchor chain fixed at one end of the iron anchor to rotate on the winding roller, thereby realizing the operation of the windlass to retrieve the anchor.

[0003] During the process of dropping the anchor by the windlass, the ship crew cannot control the rotation of the winding roller in real time, making it impossible for the ship crew to accurately control the length of the anchor chain paid out and retrieved, thus increasing the difficulty of using the windlass for the ship crew. Summary of the Invention

[0004] In order to improve the problem of the ship crew controlling the rotation of the winding roller, this application provides a monitoring device for an anchor and windlass combination machine.

[0005] A monitoring device for an anchor and windlass combination machine provided by this application adopts the following technical solution:

[0006] A monitoring device for an anchor and windlass combination machine includes a frame, an anchor chain winding roller, a clutch assembly and a main shaft. The main shaft is rotatably connected to the frame. The anchor chain winding roller is connected to the frame. The main shaft coaxially penetrates the anchor chain winding roller. The outer circumference of the anchor chain winding roller is for the anchor chain to wind around. The clutch assembly includes a clutch oil cylinder, a clutch fork and a clutch chuck. The clutch chuck is coaxially provided with a clutch keyway for the main shaft to penetrate. The clutch chuck is spacedly connected with a plurality of clutch blocks. The anchor chain winding roller is spacedly provided with a plurality of clutch grooves for the clutch blocks to be embedded in. The outer circumferential wall of the clutch chuck is coaxially provided with a clutch ring groove for the end of the clutch fork to be embedded in. The clutch oil cylinder is connected to the frame. The clutch oil cylinder is located on the side of the clutch chuck away from the anchor chain winding roller. The end of the clutch fork away from the clutch chuck is rotatably connected to the piston rod of the clutch oil cylinder. When the piston rod of the clutch oil cylinder contracts, it drives the clutch fork to approach the anchor chain winding roller, drives the clutch chuck to approach the anchor chain winding roller, and the clutch blocks are respectively embedded in the clutch grooves. The clutch chuck receives the power of the main shaft and drives the anchor chain winding roller to rotate, and the anchor chain winds around the anchor chain winding roller.

[0007] By adopting the above technical solution, one end of the clutch fork is rotatably connected to the piston rod of the clutch cylinder. The other end of the clutch fork is embedded in the clutch ring groove. The main shaft coaxially penetrates through the clutch key groove. When the main shaft rotates, it drives the clutch chuck to rotate. At the same time, the clutch fork is in rolling contact with the inner wall of the clutch ring groove. When the ship's crew needs to retract the anchor chain, the ship's crew drives the piston rod of the clutch cylinder to contract. The clutch cylinder is located on the side of the clutch chuck away from the anchor chain winding roller, driving the clutch fork to move towards the side close to the anchor chain winding roller, driving the clutch chuck to approach the anchor chain winding roller along the axis of the main shaft. The clutch blocks and the clutch grooves correspond to each other and are embedded, realizing the connection between the clutch chuck and the anchor chain winding roller. At the same time, the rotation of the main shaft drives the clutch chuck to rotate, driving the anchor chain winding roller to rotate, and the anchor chain is stably wound around the outer wall of the anchor chain winding roller, realizing the automatic retraction of the anchor chain; when the length of the anchor chain meets the retracting and releasing length, the ship's crew drives the piston rod of the clutch cylinder to extend, driving the clutch fork to move away from the side of the anchor chain winding roller, driving the clutch chuck to move away from the anchor chain winding roller along the axis of the main shaft, and the clutch blocks are separated from the clutch grooves, realizing the separation between the clutch chuck and the anchor chain winding roller. The power of the anchor chain winding roller from the clutch chuck disappears, realizing the automatic stop of the anchor chain winding roller from rotating on the frame. The length of the anchor chain meets the retracting and releasing length of the anchor chain desired by the ship's crew, enabling the ship's crew to accurately control the retracting and releasing length of the anchor chain, thereby reducing the difficulty of using the windlass by the ship's crew.

[0008] Optionally, a cable winding roller is connected to the frame. The cable winding roller is used for winding the cable. The end of the main shaft away from the anchor chain winding roller coaxially penetrates through the cable winding roller. There are two clutch assemblies. One of the clutch assemblies is connected to the anchor chain winding roller, and the other clutch assembly is connected to the cable winding roller.

[0009] By adopting the above technical solution, when the ship's crew needs to store the cable, the clutch assembly receives the power of the main shaft and drives the cable winding roller to rotate, driving the cable to be stably wound around the outer wall of the cable winding roller, realizing the automatic winding of the cable, realizing the main shaft to directionally start the rotation of the cable winding roller and the anchor chain winding roller, so that the cable winding roller and the anchor chain winding roller do not need to be respectively installed with a main shaft drive, thereby reducing the production cost of the monitoring device of the windlass combination machine.

[0010] Optionally, a proximity switch is connected to the frame. The sensing surface of the proximity switch faces the clutch fork. The proximity switch is used to monitor the movement of the clutch fork.

[0011] By adopting the above technical solution, the telescopic movement of the piston rod of the clutch cylinder drives the clutch fork to move, thereby controlling the engagement and disengagement between the clutch chuck and the anchor chain winding roller; the proximity switch is connected to the frame, and the sensing surface of the proximity switch faces the clutch fork. The proximity switch can monitor the movement of the clutch fork in real time, enabling the ship's crew to monitor the engagement and disengagement between the clutch chuck and the anchor chain winding roller in real time through the displacement of the clutch fork, thereby ensuring the stability of the operation of the anchor chain winding roller.

[0012] Optionally, a counter is connected to the frame, the sensing surface of the counter faces the anchor chain winding roller, a counting block for triggering the sensing surface of the counter is connected to the anchor chain winding roller. When the anchor chain winding roller rotates, it drives the counting block to trigger the sensing surface of the counter, and the counter is triggered to count.

[0013] By adopting the above technical solution, the counter is connected to the frame, the sensing surface of the counter faces the anchor chain winding roller. When the anchor chain winding roller rotates, it drives the counting block to approach the counting sensing surface, and the counting sensing surface is triggered to count, realizing that the counter records the number of rotations of the anchor chain winding roller in real time, and realizing the accurate monitoring of the length of the anchor chain retracted and released by the ship's crew.

[0014] Optionally, a plurality of counting blocks are connected, and the plurality of counting blocks are evenly distributed at intervals around the axis of the anchor chain winding roller.

[0015] By adopting the above technical solution, the plurality of counting blocks are evenly distributed at intervals around the axis of the anchor chain winding roller. When the anchor chain winding roller rotates, it drives the plurality of counting blocks to pass through the sensing surface of the counter in sequence, and the counter counts in real time, further accurately monitoring the rotation angle of the anchor chain winding roller, thereby improving the accurate monitoring of the length of the anchor chain retracted and released by the ship's crew.

[0016] Optionally, a cooling fan is rotatably connected to the clutch fork, and the air outlet end of the cooling fan faces the anchor chain winding roller.

[0017] By adopting the above technical solution, when the clutch chuck drives the anchor chain winding roller to rotate, part of the kinetic energy of the anchor chain winding roller on the frame is converted into heat energy, and the temperature of the anchor chain winding roller rises. The cooling fan is rotatably connected to the clutch fork, the air outlet end of the cooling fan faces the anchor chain winding roller, and the cooling fan drives the air flow to blow towards the anchor chain winding roller, realizing the cooling of the anchor chain winding roller, making it not easy for the anchor chain winding roller to heat up and deform, thereby ensuring the stability of the connection between the anchor chain winding roller and the clutch chuck.

[0018] Optionally, a driving component is connected to the clutch fork. The driving component includes a transmission wheel, two synchronous wheels and a synchronous belt used in cooperation with the synchronous wheels. The transmission wheel is rotatably connected to the clutch fork, the rotation axis of the transmission wheel is parallel to the axis of the clutch chuck, and the wheel surface of the transmission wheel is in rolling contact with the wheel surface of the clutch chuck; one of the synchronous wheels is coaxially connected to the transmission wheel, and the other synchronous wheel is coaxially connected to the rotating shaft of the cooling fan. The synchronous belt is tensioned and connected to the two synchronous wheels. When the clutch chuck rotates, it drives the transmission wheel to rotate, driving the cooling fan to rotate.

[0019] By adopting the above technical solution, when the main shaft rotates to drive the clutch chuck to rotate, the rolling surface of the transmission wheel is in rolling contact with the rolling surface of the clutch chuck. The synchronous belt is tensioned to connect the two synchronous wheels, driving the two synchronous wheels to rotate, thereby driving the cooling fan to rotate. The cooling fan drives the air flow to blow towards the anchor chain winding roller, achieving the cooling of the anchor chain winding roller. There is no need for an external power device to drive the cooling fan to rotate, reducing energy loss and reflecting the concept of energy conservation.

[0020] Optionally, a cooling flow channel is provided on the end face of the anchor chain winding roller facing the cooling fan. The cooling flow channel penetrates the anchor chain winding roller towards the direction close to the main shaft. The cooling fan drives the air flow to impact the main shaft through the cooling flow channel.

[0021] By adopting the above technical solution, one end of the cooling flow channel faces the cooling fan, and the other end faces the main shaft passing through the anchor chain winding roller. The cooling fan drives the air flow to impact the main shaft through the cooling flow channel, achieving the cooling of the main shaft, making it difficult for the main shaft to heat up during long-term operation, and thus ensuring the stability of the main shaft operation.

[0022] Optionally, an opening and closing assembly is connected to the anchor chain winding roller. An opening and closing cavity for accommodating the opening and closing assembly is provided on the inner wall of the cooling flow channel close to the cooling fan. The opening and closing cavity penetrates the anchor chain winding roller towards the direction close to the main shaft. The opening and closing assembly includes a thermal expansion and contraction strip and an opening and closing plate. The opening and closing plate is slidably connected to the inner wall of the opening and closing cavity. The opening and closing plate can close the cooling flow channel. One end of the thermal expansion and contraction strip is connected to the opening and closing plate, and the other end of the thermal expansion and contraction strip faces the main shaft. When the anchor chain winding roller heats up and transfers heat energy to the thermal expansion and contraction strip, the thermal expansion and contraction strip heats up and expands, driving the opening and closing plate to slide, and the closing effect of the opening and closing plate on the cooling flow channel disappears.

[0023] By adopting the above technical solution, one end of the thermal expansion and contraction strip is connected to the opening and closing plate, and the other end faces the main shaft. The opening and closing plate is located in the opening and closing cavity and closes the cooling flow channel, making it difficult for external impurities to enter the connection between the main shaft and the anchor chain winding roller through the cooling flow channel, thus ensuring the stability of the main shaft rotating in the anchor chain winding roller; when the clutch chuck drives the anchor chain winding roller to rotate, part of the kinetic energy of the anchor chain winding roller itself is converted into internal energy, and the anchor chain winding roller transfers part of the heat energy to the thermal expansion and contraction strip. The thermal expansion and contraction strip heats up and expands, driving the opening and closing plate to slide away from the cooling flow channel, making the closing effect of the opening and closing plate on the cooling flow channel disappear. The cooling fan stably drives the air flow into the cooling flow channel, and the anchor chain winding roller exchanges heat with the air flow to achieve the cooling of the anchor chain winding roller; at the same time, the end of the thermal expansion and contraction strip faces the main shaft. When the main shaft converts part of its kinetic energy into heat energy, the main shaft transfers the heat energy to the thermal expansion and contraction strip through thermal radiation. The thermal expansion and contraction strip heats up and expands, driving the opening and closing plate to slide away from the cooling flow channel, and the closing effect of the opening and closing plate on the cooling flow channel disappears. The cooling fan drives the air flow to impact the main shaft through the cooling flow channel, achieving the cooling of the main shaft.

[0024] Optionally, a cooling ring groove is coaxially formed on the inner wall of the inner ring of the anchor chain winding roller, the cooling ring groove communicates with a cooling flow channel, and the cooling ring groove surrounds the main shaft.

[0025] By adopting the above technical solution, when the cooling fan drives the air flow to enter the cooling ring groove through the cooling flow channel, the cooling ring groove surrounds the main shaft, increasing the contact area between the air flow and the main shaft, improving the heat exchange rate between the main shaft and the air flow, and making the main shaft not easily operate at a high temperature for a long time, thereby improving the operating stability of the anchor winch.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. The setting of the clutch oil cylinder, the clutch fork and the clutch chuck realizes the automatic stop rotation of the anchor chain winding roller on the rack, and the length of the anchor chain conforms to the length of the anchor chain retraction and release desired by the ship's crew, enabling the ship's crew to accurately control the retraction and release length of the anchor chain, thereby reducing the difficulty of using the anchor winch by the ship's crew;

[0028] 2. The setting of the proximity switch enables the ship's crew to monitor the clutch situation between the clutch chuck and the anchor chain winding roller in real time through the displacement of the clutch fork, thereby ensuring the operating stability of the anchor chain winding roller;

[0035] The following further elaborates on this application in conjunction with the attached Figures 1-4 drawings.

[0036] The embodiment of this application discloses a monitoring device for an anchor and winch combination machine. Refer to Figure 1 , the monitoring device for the anchor and winch combination machine includes a frame 1, an anchor chain winding roller 2, a cable winding roller 3, a main shaft 4, and two clutch assemblies 5. The main shaft 4 is rotatably connected to the frame 1 along its own axis. Both the cable winding roller 3 and the anchor chain winding roller 2 are connected to the frame 1, and both the anchor chain winding roller 2 and the cable winding roller 3 are coaxially sleeved on the main shaft 4. The anchor chain winding roller 2 and the cable winding roller 3 are located at both ends in the axial direction of the main shaft 4. The anchor chain winding roller 2 is used for winding the anchor chain, and the cable winding roller 3 is used for winding the cable. The two clutch assemblies 5 are connected to the frame 1. One of the clutch assemblies 5 is connected to the anchor chain winding roller 2, and the other clutch assembly 5 is connected to the cable winding roller 3. The clutch assembly 5 is used to receive the power of the main shaft 4 and drive the cable winding roller 3 or the anchor chain winding roller 2 to rotate.

[0037] Refer to Figure 1 and Figure 2 , two hydraulic belt brakes 14 are installed on the frame 1. One of the hydraulic belt brakes 14 is used to control the braking of the anchor chain winding roller 2, and the other hydraulic belt brake 14 is used to control the braking of the cable winding roller 3. The clutch assembly 5 includes a clutch oil cylinder 51, a clutch fork 52, and a clutch chuck 53. In the embodiment of this application, the clutch chuck 53 is a cylinder. The clutch chuck 53 is coaxially provided with a clutch keyway 531 for the main shaft 4 to pass through. A plurality of clutch blocks 6 are fixedly welded to the end face of the clutch chuck 53. The plurality of clutch blocks 6 are evenly distributed along the axis of the clutch chuck 53. A plurality of clutch grooves 21 are spaced apart on both the cable winding roller 3 and the anchor chain winding roller 2. The plurality of clutch grooves 21 are evenly spaced along the axis of the cable winding roller 3 or the anchor chain winding roller 2. The clutch blocks 6 correspond to the clutch grooves 21 one by one and are embedded therein.

[0038] Refer to Figure 2, a clutch ring groove 532 for the end of the clutch fork 52 to be inserted is coaxially provided on the outer wall of the circumferential direction of the clutch chuck 53. The clutch oil cylinder 51 is connected to the frame 1. The end of the clutch fork 52 away from the clutch chuck 53 is rotatably connected to the piston rod of the clutch oil cylinder 51. The clutch oil cylinder 51 is located on the side of the clutch fork 52 away from the clutch block 6. When the anchor chain needs to be retracted or released, the piston rod of the clutch oil cylinder 51 contracts, driving the clutch fork 52 to rotate towards the direction close to the anchor chain winding roller 2, driving the clutch chuck 53 to approach the anchor chain winding roller 2 along the axis of the main shaft 4. The clutch blocks 6 correspond to the clutch grooves 21 one by one and are inserted. The outer wall of the circumferential direction of the clutch blocks 6 abuts against the inner wall of the clutch grooves 21 to form a fixation. At the same time, the rotation of the main shaft 4 drives the rotation of the clutch chuck 53, driving the anchor chain winding roller 2 to rotate around its own axis, and the anchor chain is stably wound on the outer wall of the circumferential direction of the anchor chain winding roller 2, realizing the retraction and release of the anchor chain on the anchor chain winding roller 2; when the retraction and release length of the anchor chain is appropriate, the piston rod of the clutch oil cylinder 51 extends, driving the clutch fork 52 to rotate towards the direction away from the anchor chain winding roller 2, driving the clutch chuck 53 to move away from the anchor chain winding roller 2 along the axis of the main shaft 4, and the clutch blocks 6 are disengaged from the clutch grooves 21, realizing the stop rotation of the anchor chain winding roller 2, making the length of the anchor chain meet the retraction and release length of the anchor chain desired by the ship's crew, realizing the precise control of the retraction and release length of the anchor chain by the ship's crew, thereby reducing the use difficulty of the ship's crew for the windlass.

[0039] Refer to Figure 1 , two proximity switches 7 are fixed on the frame 1. One of the proximity switches 7 has its sensing surface facing the clutch fork 52 corresponding to the anchor chain winding roller 2, and the other proximity switch 7 has its sensing surface facing the clutch fork 52 corresponding to the cable winding roller 3. The proximity switch 7 is used to monitor the movement of the clutch fork 52, enabling the ship's crew to directly know the engagement and disengagement situation between the clutch chuck 53 and the anchor chain winding roller 2 through the displacement situation of the clutch fork 52, thereby ensuring the stability of the operation of the anchor chain winding roller 2.

[0040] Refer to Figure 1 , a counter 8 is connected to the frame 1. In the embodiment of the present application, the counter 8 is a grating counter 8. The sensing surface of the counter 8 faces the anchor chain winding roller 2. A counting block 9 is fixed on the end face of the anchor chain winding roller 2 facing the counter 8. The number of the counting blocks 9 can be one, two or more. In the embodiment of the present application, the number of the counting blocks 9 is multiple, and the multiple counting blocks 9 are evenly distributed at intervals around the axis of the anchor chain winding roller 2. When the anchor chain winding roller 2 rotates and drives the multiple counting blocks 9 to pass through the sensing surface of the counter 8 in sequence, the sensing surface of the counter 8 is triggered and counts the passing times of the counting blocks 9, enabling the ship's crew to precisely control the rotation times and rotation of the anchor chain winding roller 2, realizing the precise control of the retraction and release length of the anchor chain, and further improving the simplicity of the ship's crew using the windlass.

[0041] Refer to Figure 2 and Figure 3, a cooling fan 10 is rotatably connected to the end face of the clutch fork 52 facing the anchor chain winding roller 2. The rotation axis of the cooling fan 10 is parallel to the axis of the main shaft 4, and the air outlet end of the cooling fan 10 faces the anchor chain winding roller 2. A driving assembly 11 is connected to the clutch fork 52, and the driving assembly 11 is used to drive the cooling fan 10 to rotate around its own axis. The driving assembly 11 includes a transmission wheel 111, two synchronous wheels 112 and a synchronous belt 113 used in conjunction with the synchronous wheels 112. The transmission wheel 111 is rotatably connected to the clutch fork 52. The rotation axis of the transmission wheel 111 is parallel to the rotation axis of the cooling fan 10, and the wheel surface of the transmission wheel 111 is in rolling contact with the outer circumferential wall of the clutch chuck 53. The transmission wheel 111 is located between the cooling fan 10 and the clutch chuck 53. One of the synchronous wheels 112 is coaxially fixed to the rotating shaft of the transmission wheel 111, and the other synchronous wheel 112 is coaxially fixed to the rotating shaft of the cooling fan 10. The synchronous belt 113 is tensioned to connect the two synchronous wheels 112.

[0042] Referring to Figure 2 and Figure 3 , when the main shaft 4 rotates to drive the clutch chuck 53 to rotate, the transmission wheel 111 is in rolling contact with the clutch chuck 53, driving the two synchronous wheels 112 to rotate, driving the cooling fan 10 to rotate along its own axis, and the cooling fan 10 drives the air flow to impact the roller surface of the anchor chain winding roller 2 to achieve cooling of the anchor chain winding roller 2.

[0043] Referring to Figure 2 and Figure 4 , a cooling flow channel 22 is formed on the end face of the anchor chain winding roller 2 facing the cooling fan 10. The number of the cooling flow channels 22 can be one, two or more. In the embodiment of the present application, the number of the cooling flow channels 22 is multiple, and the multiple cooling flow channels 22 are evenly distributed at intervals around the axis of the anchor chain winding roller 2. The cooling flow channel 22 penetrates the anchor chain winding roller 2 in the direction close to the axis of the anchor chain winding roller 2.

[0044] Referring to Figure 2 and Figure 4 , a cooling ring groove 23 is coaxially formed on the inner circumferential wall of the anchor chain winding roller 2. The cooling ring groove 23 surrounds the main shaft 4, and the cooling ring groove 23 communicates with the cooling flow channel 22. When the cooling fan 10 rotates, it drives the air flow to enter the cooling ring groove 23 through the cooling flow channel 22, increasing the contact area between the air flow and the main shaft 4, enabling the main shaft 4 to stably transfer heat energy to the air flow, achieving cooling of the main shaft 4, preventing the main shaft 4 from being damaged due to long-term operation at a high temperature, and thus extending the service life of the main shaft 4.

[0045] Referring to Figure 2 and Figure 4, a plurality of opening and closing components 12 are connected to the anchor chain winding roller 2, the opening and closing components 12 correspond to the cooling flow channels 22 one by one, an opening and closing cavity 24 for accommodating the opening and closing components 12 is formed in the inner wall of the cooling flow channel 22 close to the cooling fan 10, a step surface 25 is formed at the connection between the opening and closing cavity 24 and the cooling flow channel 22, and the opening and closing cavity 24 penetrates the anchor chain winding roller 2 in the direction close to the axis of the anchor chain winding roller 2. The opening and closing component 12 includes a thermal expansion and contraction strip 121 and an opening and closing plate 122. The opening and closing plate 122 is slidably connected to the step surface 25, and the sliding direction of the opening and closing plate 122 is perpendicular to the axis of the anchor chain winding roller 2. When the opening and closing plate 122 slides in the direction close to the axis of the anchor chain winding roller 2, the plate surface of the opening and closing plate 122 abuts against the step surface 25 and closes the cooling flow channel 22, so that external impurities are not easily introduced into the cooling annular groove 23 through the cooling flow channel 22, thereby ensuring the stability of the rotation of the main shaft 4 in the anchor chain winding roller 2.

[0046] Referring to Figure 2 and Figure 4 , in the embodiment of the present application, the material of the thermal expansion and contraction strip 121 is nylon, which has a certain coefficient of thermal expansion. The thermal expansion and contraction strip 121 is embedded in the opening and closing cavity 24. One end of the thermal expansion and contraction strip 121 is fixed on the side of the opening and closing plate 122 close to the axis of the anchor chain winding roller 2, the other end of the thermal expansion and contraction strip 121 faces the main shaft 4, and the end of the thermal expansion and contraction strip 121 is flush with the inner wall of the inner ring of the anchor chain winding roller 2.

[0047] Referring to Figure 2 and Figure 4 , when the anchor chain winding roller 2 operates for a long time, the anchor chain winding roller 2 converts part of its kinetic energy into heat energy. The anchor chain winding roller 2 transfers the heat energy to the thermal expansion and contraction strip 121 by heat conduction. The thermal expansion and contraction strip 121 expands due to heat and drives the opening and closing plate 122 to slide in the direction away from the axis of the anchor chain winding roller 2. The closing effect of the opening and closing plate 122 on the cooling flow channel 22 disappears. The cooling fan 10 stably drives the air flow to sequentially pass through the opening and closing cavity 24, the cooling flow channel 22 and enter the cooling annular groove 23, so that the heat energy of the main shaft 4 and the anchor chain winding roller 2 is stably transferred to the air flow, realizing the cooling of the main shaft 4 and the anchor chain winding roller 2.

[0048] Referring to Figure 4 , a slider 13 is fixed on the side of the opening and closing plate 122 facing the step surface 25. A sliding groove 26 for the slider 13 to slide is formed on the step surface 25. When the thermal expansion and contraction strip 121 expands due to heat and drives the opening and closing plate 122 to slide, the slider 13 is slidably connected to the inner wall of the sliding groove 26, so that the opening and closing plate 122 is not easily deflected when sliding on the step surface 25, thereby improving the stability of the opening and closing plate 122 when sliding on the step surface 25.

[0049] The implementation principle of a monitoring device for an anchor and winch combination machine in an embodiment of this application is as follows: When the anchor chain needs to be wound or unwound, the piston rod of the clutch oil cylinder 51 contracts, driving the clutch fork 52 to rotate towards the direction close to the anchor chain winding roller 2, driving the clutch chuck 53 to approach the anchor chain winding roller 2 along the axis of the main shaft 4. The clutch blocks 6 correspond to the clutch grooves 21 one by one and are embedded. The outer circumferential wall of the clutch block 6 abuts against the inner wall of the clutch groove 21 to form a fixation. At the same time, the rotation of the main shaft 4 drives the clutch chuck 53 to rotate, driving the anchor chain winding roller 2 to rotate around its own axis, and the anchor chain is stably wound around the outer circumferential wall of the anchor chain winding roller 2, realizing the winding and unwinding of the anchor chain on the anchor chain winding roller 2. When the length of the anchor chain wound or unwound is appropriate, the piston rod of the clutch oil cylinder 51 extends, driving the clutch fork 52 to rotate away from the anchor chain winding roller 2, driving the clutch chuck 53 to move away from the anchor chain winding roller 2 along the axis of the main shaft 4, and the clutch blocks 6 disengage from the clutch grooves 21, realizing the stop rotation of the anchor chain winding roller 2, making the length of the anchor chain conform to the length of the anchor chain wound or unwound desired by the ship's crew, realizing the precise control of the ship's crew over the length of the anchor chain wound or unwound, and thus reducing the difficulty of use of the anchor and winch by the ship's crew.

[0050] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
