Abstract
Description
Technical Field
[0001] This invention relates to the field of winch drum technology, specifically to lightweight winch drums and methods for ship hydrological and geological survey winches. Background Technology
[0002] A winch, also known as a "winding machine," is a mechanical device that uses a drum to wind a steel wire rope or chain to lift, pull, or drag heavy objects. Winches are indispensable power devices in many fields such as construction, shipbuilding, mining, rescue, and stage setting. They are mainly composed of core components such as a power unit, a reduction mechanism, a drum, a braking system, a steel wire rope, and safety devices.
[0003] Publication No. CN105417418A discloses a drum and its hoisting mechanism, belonging to the field of cranes. The drum includes a first drum section and a second drum section arranged coaxially. The pitch t and rotation direction of the rope grooves on the first drum section and the second drum section are the same. The difference between the outer diameter D1 of the first drum section and the outer diameter D2 of the second drum section is equal to 2 × pitch t / π. The drum provided in the above application embodiment is used in the hoisting mechanism of a double-rope right-angle rope arranger. For each revolution of the steel wire rope wound by the drum, the rope arranger that cooperates with it travels a distance of one pitch along the axis of the drum. Then, one steel wire rope is pulled up by one pitch length, and the other steel wire rope is released by one pitch length. The difference in the stroke of the two steel wire ropes is 2 × pitch. This invention compensates for the difference in the stroke of the two steel wire ropes during the rope arrangement process by setting the difference in the outer diameter of the first drum section and the second drum section.
[0004] While the aforementioned applications and existing technologies can effectively solve the problem of rope tangling, when these technologies are used in the hydrological and geological survey winches, the steel wire rope on the drum surface needs to enter the sea. During the winding process, sand and other debris from the seabed adhere to the surface of the steel wire rope, causing wear on the drum and affecting its service life. Furthermore, after removing the sand and debris from the drum surface, the protective oil layer on the steel wire rope surface is removed, leading to dry friction between the steel wire rope and the drum, which in turn damages the drum. Moreover, when applying a protective oil layer to the surface of the steel wire rope, the presence of moisture inside and on the surface of the steel wire rope causes an emulsification reaction between the protective oil layer and the moisture, rendering the protective oil layer ineffective. Therefore, this invention proposes a lightweight drum and method for winches used in marine hydrological and geological surveys. Summary of the Invention
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a lightweight winch drum and method for marine hydrological and geological survey winches. It offers advantages such as preventing sand and gravel abrasion, removing moisture, and preventing dry friction. This solves the problems in the aforementioned applications and existing technologies where, during the use of hydrological and geological survey winches, the steel wire rope on the drum surface needs to enter the sea, causing sand and gravel from the seabed to adhere to the surface of the wire rope during winding. This leads to sand and gravel abrasion of the drum, affecting its service life. Furthermore, removing the sand and gravel from the drum surface removes the protective oil layer on the wire rope, causing dry friction between the wire rope and the drum, resulting in drum damage. Additionally, when applying a protective oil layer to the wire rope surface, the presence of moisture inside and on the surface of the wire rope causes an emulsification reaction between the protective oil layer and the moisture, rendering the protective oil layer ineffective.
[0006] (II) Technical Solution To achieve the aforementioned objectives of preventing abrasion from sand and gravel, drying out moisture, and preventing dry grinding, this invention provides the following technical solution: a lightweight winch drum for shipboard hydrological and geological survey winches, comprising: a support frame and a drum body disposed inside the support frame.

[0010] Furthermore, the bottom of each of the aforementioned pumping cylinders is fixedly connected to a pumping pipe, which is located inside the water tank. The surface of the pumping pipe is provided with an annular disk and a rotating disk. The anti-wear assembly also includes a fixed rod rotatably connected inside the treatment tank and a rotating shaft rotatably connected inside the treatment tank.

The driven gear ring meshes with the drive gear for transmission.
[0011] Furthermore, the water-spinning assembly includes a rotating rod rotatably connected inside the treatment tank and a fixed cylinder fixedly connected inside the treatment tank. A cam is fixedly connected to the surface of the rotating rod, and several rotating arc blades are fixedly connected to the surface of the rotating rod and inside the annular disk.
[0012] Furthermore, a sliding disc is slidably connected inside the fixed cylinder, a first spring is fixedly connected to the bottom of the sliding disc, an extension rod is fixedly connected to the top of the sliding disc, a squeezing plate is fixedly connected to the surface of the extension rod, and a water-pumping semi-ring is fixedly connected to the top of the extension rod.

[0015] This invention also provides a method for lightweighting the winch drum for marine hydrological and geological survey winches, which specifically includes the following steps: Step 1: When it is necessary to wind up the wire rope on the surface of the drum, the first rotating rod drives the drum to rotate, so that the drum winds up the wire rope. Step 2: The first rotating rod drives the anti-wear component through the power component, so that the anti-wear component can treat the debris on the surface of the wire rope and prevent the debris from adhering to the surface of the wire rope and abrading the drum. Step 3: When the anti-wear component is in operation, the water-spraying component is driven synchronously so that the water-spraying component can remove the water inside the wire rope and prevent the water from affecting the application of lubricating oil. Step 4: When the spin-drying component is in operation, the dry grinding component is driven synchronously to apply lubricating oil to the surface of the wire rope, thereby preventing the bare wire rope from dry grinding against the drum.
[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a lightweight drum and method for winches used in marine hydrological and geological surveys, which has the following beneficial effects: 1. The lightweight drum and method of the winch used in hydrological and geological surveys on this ship utilizes a power assembly and an anti-wear assembly. When the first rotating rod reverses, it drives the first fixed plate to rotate via the power assembly. This causes the lifting plate to pump water from the tank through the water supply pipe to the water collection pan via the squeezing rod, squeezing pan, and pumping cylinder. The water collection pan then uses a pressurized nozzle to flush the wire rope. Simultaneously, the water flow drives the fixed rod to rotate via the fixed arc plate, causing the drive gear to rotate the brush ring via the driven gear ring. The brush bristles inside the brush ring treat the sand and gravel adhering to the surface of the wire rope. Through water flushing and washing, the sand and gravel are treated, preventing damage to the drum body and thus achieving the effect of preventing sand and gravel wear.
[0017] 2. The lightweight drum and method of the winch used in the hydrological and geological survey of this ship utilizes a combination of anti-wear components and a water-throwing component. When water enters the annular disc, the water flow drives the rotating rod to rotate via a rotating arc plate. The rotating rod then squeezes the extrusion plate via a cam, which in turn squeezes the first spring via an extension rod and a sliding disc. As the rotating rod continues to rotate, when the cam and the extrusion plate are no longer in contact, the first spring quickly returns to its initial state. This causes the sliding disc to drive the water-beating half-ring via the extension rod to beat the wire rope, thus removing moisture from the wire rope and preventing it from affecting subsequent oiling treatment. This achieves the effect of drying out the water.
[0018] 3. The lightweight drum and method of the winch used in the hydrological and geological survey winch of this ship, through the combined use of the water-throwing component and the dry-grinding component, the rotating rod drives the cam to rotate, which in turn drives the second fixed plate to rotate. The second fixed plate drives the sliding disk to move through the transmission plate, which in turn drives the tension rod to move through the iron plate. The tension rod drives the suction plate to move inside the suction cylinder, thereby transferring the protective oil inside the oil tank to the inside of the suction cylinder through the oil extraction pipe and stretching the second spring. As the second fixed plate continues to rotate, when the sliding disk and the iron plate separate, the second spring slowly draws the protective oil inside the suction cylinder into the oil coating cylinder through the oil outlet pipe via the suction plate. As the second fixed plate continues to rotate, the sliding disk and the iron plate re-adhere. As the wire rope is continuously wound, its surface is coated with oil as it passes through the inside of the oil coating cylinder, thereby achieving the effect of preventing dry grinding.

In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.
[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 2 A lightweight winch drum for shipboard hydrogeological survey winches includes: a support frame 1 and a drum body 111 disposed inside the support frame 1. The first rotating rod 11 is rotatably connected inside the support frame 1. The cylinder 111 is fixedly connected to the surface of the first rotating rod 11. A water tank 13 is provided on the surface of the support frame 1, and a treatment box 14 is provided at the bottom of the cylinder 111. The anti-wear component 3 is installed inside the treatment tank 14 to prevent debris adhering to the steel wire rope on the surface of the cylinder 111 from abrading the cylinder 111. The anti-wear component 3 includes several pumping cylinders 33 fixedly connected to the top of the water tank 13 and a water collection plate 34 fixedly connected inside the treatment tank 14. Several booster nozzles 341 are fixedly connected inside the water collection plate 34. The pumping cylinders 33 and the water collection plate 34 are connected through a water supply pipe 332. A transmission box 12 is provided at one end of the first rotating rod 11. A receiver / discharge motor 121 is provided on the back of the transmission box 12. A protective shell 131 is fixedly connected to the top of the water tank 13. The power assembly 2 is located on the top of the water tank 13 and is used to provide power to the anti-wear assembly 3 when the cylinder 111 winds up the wire rope. The water-removing component 4 is located inside the treatment box 14 and is used to remove the water inside the wire rope after treatment, so as not to affect the subsequent application of lubricating oil. The dry grinding component 5 is located inside the processing box 14 and is used to apply lubricating oil to the processed wire rope to prevent the wire rope from abrading the cylinder 111. It should be noted that the transmission box 12 is equipped with a reduction mechanism, which is existing technology and will not be described in detail here. When it is necessary to wind the wire rope onto the surface of the drum 111, start the winding and unwinding machine 121. The winding and unwinding machine 121 drives the first rotating rod 11 to rotate through the transmission box 12, causing the first rotating rod 11 to drive the drum 111 to reverse. The reverse rotation of the drum 111 winds the wire rope onto the surface of the drum 111. For a specific embodiment two, please refer to Figures 1 to 9 Based on the lightweight winch drum for ship hydrological and geological survey winches provided in Specific Embodiment 1, this embodiment provides a further technical solution: The power assembly 2 includes a ratchet 21 fixedly connected to the surface of the first rotating rod 11 and a second rotating rod 22 rotatably connected inside the protective shell 131. A storage tray 221 is fixedly connected to one end of the second rotating rod 22, and a pawl 222 is rotatably connected inside the storage tray 221. The pawl 222 can engage with the ratchet 21. The anti-wear assembly 3 also includes a first fixed plate 31 fixedly connected to one end of the second rotating rod 22 and a lifting plate 32 slidably connected inside the protective shell 131. A transmission bar 311 is rotatably connected to the surface of the first fixed plate 31, and the bottom of the transmission bar 311 is hinged to the top of the lifting plate 32. Several pressing rods 321 are fixedly connected to the bottom of the lifting plate 32, and pressing plates 32 are fixedly connected to the bottom of each pressing rod 321. 2. The extrusion plate 322 is slidably connected to the inside of the water pump 33. The bottom of several water pumps 33 are all fixedly connected to the water pump pipe 331. The water pump pipe 331 is set inside the water tank 13. The surface of the water supply pipe 332 is provided with an annular plate 342 and a rotating plate 343. The anti-wear component 3 also includes a fixed rod 35 rotatably connected to the inside of the processing box 14 and a rotating shaft 36 rotatably connected to the inside of the processing box 14. Several fixed arc plates 351 are fixedly connected to the surface of the fixed rod 35 and located inside the rotating plate 343. A drive gear 352 is fixedly connected to the surface of the fixed rod 35. A brush ring 361 is fixedly connected to the inside of the rotating shaft 36. A passive gear ring 362 is fixedly connected to one end of the brush ring 361. The passive gear ring 362 meshes with the drive gear 352 for transmission. It should be noted that when the ratchet 21 rotates clockwise, the ratchet 21 can drive the pawl 222 to rotate 50 degrees inside the storage tray 221. When the ratchet 21 rotates counterclockwise, the ratchet 21 can drive the storage tray 221 to rotate through the pawl 222. The surface of the water pump pipe 331 is provided with a first one-way valve, and the surface of the water supply pipe 332 is provided with a second one-way valve. When the first one-way valve is open, the second one-way valve is closed, and when the second one-way valve is open, the first one-way valve is closed. When it is necessary to remove sand and gravel debris from the surface of the wire rope to prevent it from abrading the cylinder 111, the first rotating rod 11 drives the cylinder 111 to reverse direction. This causes the ratchet 21 and pawl 222 to rotate the receiving tray 221. The receiving tray 221 then drives the first fixed plate 31 to rotate via the second rotating rod 22. The first fixed plate 31 drives the lifting plate 32 to rise and fall continuously via the transmission bar 311. When the lifting plate 32 drives the pressing rod 321 and the pressing plate 322 to rise, the water pump 33 pumps water from the water tank 13 into its interior through the water pump pipe 331. When the lifting plate 32 drives the pressing rod 321 and the pressing plate 322 to fall, the water pump 33... Water flows into the annular disc 342, rotating disc 343, and collecting disc 34 through the water supply pipe 332. When the water flows into the rotating disc 343, the water flows through the fixed arc plate 351 to drive the fixed rod 35 to rotate. The fixed rod 35 drives the passive gear ring 362 to rotate through the active gear 352. In turn, the passive gear ring 362 drives the brush bristles to rotate through the brush ring 361, so that the brush bristles can treat stubborn sand and gravel debris. When the water flows into the collecting disc 34, the water in the collecting disc 34 is sprayed out through the pressurized nozzle 341, so that the high-pressure water flow washes away sand and gravel debris, thereby treating the sand and gravel debris on the surface of the wire rope and preventing the sand and gravel debris from scratching the cylinder 111. For a specific embodiment three, please refer to Figures 1 to 12 Based on the lightweight winch drum for ship hydrological and geological survey winches provided in Specific Embodiment Two, this embodiment provides a further technical solution: The water-spraying assembly 4 includes a rotating rod 41 rotatably connected inside the treatment tank 14 and a fixed cylinder 42 fixedly connected inside the treatment tank 14. A cam 411 is fixedly connected to the surface of the rotating rod 41. Several rotating arc plates 412 are fixedly connected to the surface of the rotating rod 41 and inside the annular disk 342. A sliding disk 421 is slidably connected inside the fixed cylinder 42. A first spring 422 is fixedly connected to the bottom of the sliding disk 421. An extension rod 423 is fixedly connected to the top of the sliding disk 421. A squeezing plate 424 is fixedly connected to the surface of the extension rod 423. A water-spraying semi-ring 425 is fixedly connected to the top of the extension rod 423. When it is necessary to treat the moisture on the surface and inside of the wire rope, when the water flows into the annular disc 342, the water flows through the rotating arc plate 412 to drive the rotating rod 41 to rotate, so that the rotating rod 41 squeezes the extrusion plate 424 through the cam 411, and then the extrusion plate 424 squeezes the first spring 422 through the extension rod 423 and the sliding disc 421. As the rotating rod 41 continues to rotate, when the cam 411 and the extrusion plate 424 are no longer in contact, the first spring 422 quickly returns to its initial state, so that the sliding disc 421 drives the water-beating half ring 425 to beat the surface of the wire rope through the extension rod 423. The water inside the wire rope is removed by beating, so that the water does not affect the subsequent oiling treatment. For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 15 Based on the lightweight winch drum for ship hydrological and geological survey winches provided in Specific Embodiment 3, this embodiment provides a further technical solution: The dry grinding assembly 5 includes an oil tank 51 fixedly connected inside the processing box 14 and an oiling cylinder 55 fixedly connected inside the processing box 14. A suction cylinder 511 is fixedly connected to one side of the oil tank 51, and an oil suction pipe 512 is fixedly connected to one end of the suction cylinder 511. The suction cylinder 511 and the oiling cylinder 55 are connected through an oil outlet pipe 513. A suction cup 52 is slidably connected inside the suction cup 511. A tension rod 521 is fixedly connected to one side of the suction cup 52. A second spring 522 is fixedly connected to one side of the suction cup 52 and on the surface of the tension rod 521. An iron plate 523 is fixedly connected to one end of the tension rod 521. The dry grinding assembly 5 also includes a second fixed plate 53 fixedly connected to one end of the rotating rod 41 and a slide rail 54 fixedly connected inside the processing box 14. A transmission plate 531 is provided on the second fixed plate 53. A sliding disk 541 is slidably connected inside the slide rail 54. The sliding disk 541 and the iron plate 523 can be adsorbed. It should be noted that a third check valve is provided on the surface of the oil extraction pipe 512, and a fourth check valve is provided on the surface of the oil outlet pipe 513. When the third check valve is open, the fourth check valve is closed, and when the fourth check valve is open, the third check valve is closed. The transmission plate 531 consists of two plates. The surface of the second fixed plate 53 is rotatably connected to the first rotating plate, and the bottom surface of the first rotating plate is rotatably connected to the second rotating plate. One end of the second rotating plate is fixedly connected to one end of the sliding disk 541. When the surface of the wire rope needs to be oiled, the rotating rod 41 drives the cam 411 to rotate, which in turn drives the second fixed disk 53 to rotate. The second fixed disk 53 drives the sliding disk 541 to move through the transmission plate 531. The sliding disk 541 drives the tension rod 521 to move through the iron disk 523. The tension rod 521 drives the suction disk 52 to move inside the suction cylinder 511, thereby transferring the protective oil inside the oil tank 511 to the inside of the suction cylinder 51 through the oil extraction pipe 512 and stretching the second spring 522. As the second fixed disk 53 holds... As the sliding disk 541 and the iron disk 523 continue to rotate, the second spring 522 slowly draws the protective oil inside the suction cylinder 511 into the oiling cylinder 55 through the oil outlet pipe 513 via the suction disk 52. As the second fixed disk 53 continues to rotate, the sliding disk 541 and the iron disk 523 re-adhere to each other, thus forming a reciprocating motion. As the wire rope is continuously wound up, the surface of the wire rope is coated with oil when it passes through the oiling cylinder 55. Because the surface of the wire rope is coated with a protective oil layer, the wire rope will not cause dry friction on the cylinder 111. In a specific embodiment five, the present invention also provides a method for lightweighting the winch drum for marine hydrological and geological survey winches. This method for lightweighting the winch drum for marine winches specifically includes the following steps: Step 1: When it is necessary to wind up the wire rope on the surface of the cylinder 111, the first rotating rod 11 drives the cylinder 111 to rotate, so that the cylinder 111 winds up the wire rope. Step 2: The first rotating rod 11 drives the anti-wear component 3 through the power component 2, so that the anti-wear component 3 can treat the debris on the surface of the wire rope and prevent the debris from adhering to the surface of the wire rope and wearing the cylinder 111. Step 3: When the anti-wear component 3 is in operation, the water-spraying component 4 is driven synchronously so that the water-spraying component 4 can treat the water inside the wire rope and prevent the water from affecting the application of lubricating oil. Step 4: When the spin-drying component 4 is in operation, the dry grinding component 5 is driven synchronously so that the dry grinding component 5 applies lubricating oil to the surface of the wire rope, thereby preventing the bare wire rope from dry grinding against the drum 111.
[0025] Working principle: During use, the take-up and discharge motor 121 is started. The take-up and discharge motor 121 drives the first rotating rod 11 to rotate through the transmission box 12, causing the first rotating rod 11 to drive the drum 111 to rotate in reverse. The reverse rotation of the drum 111 winds the wire rope onto the surface of the drum 111. When it is necessary to remove sand and gravel debris from the surface of the wire rope to prevent the sand and gravel debris from abrading the drum 111, the first rotating rod 11 drives the drum 111 to rotate in reverse. This, through the ratchet 21 and pawl 222, drives the receiving plate 221 to rotate. The receiving plate 221, through the second rotating rod 22, drives the first fixed plate 31 to rotate. The first fixed plate 31, through the transmission bar 311, drives the lifting plate 32 to continuously rise and fall. When the lifting plate 32 drives the pressing rod 321 and the pressing plate 321 to rotate, the first fixed plate 31 rotates. When the pump rises, the pump cylinder 33 delivers water from the water tank 13 to its interior through the pump pipe 331. When the lifting plate 32 lowers the squeezing rod 321 and the squeezing disc 322, the water inside the pump cylinder 33 flows through the water supply pipe 332 into the annular disc 342, the rotating disc 343, and the collecting disc 34. When the water enters the rotating disc 343, it drives the fixed rod 35 to rotate through the fixed arc plate 351. The fixed rod 35 then drives the driven gear ring 362 to rotate through the drive gear 352. This causes the driven gear ring 362 to drive the brush bristles to rotate through the brush ring 361, allowing the brush bristles to process stubborn sand and gravel. When the water flows into the collecting disc 34, the water in the collecting disc 34 is pumped into the pressurized nozzle 341. The high-pressure water jet washes away sand and other debris, removing them from the surface of the wire rope and preventing them from scratching the cylinder 111. When water needs to be removed from the surface and interior of the wire rope, as the water enters the annular disc 342, the water flow drives the rotating rod 41 to rotate via the rotating arc plate 412. The rotating rod 41 then presses the pressing plate 424 via the cam 411. The pressing plate 424, in turn, presses the first spring 422 via the extension rod 423 and the sliding disc 421. As the rotating rod 41 continues to rotate, when the cam 411 and the pressing plate 424 are no longer in contact, the first spring 422 quickly returns to its initial state. This causes the sliding disc 421 to drive the water-pumping half-ring 425 to press against the wire rope via the extension rod 423. The surface of the wire rope is tapped to remove moisture from its interior, preventing it from affecting subsequent oiling. When oiling is required, the rotating rod 41 drives the cam 411 to rotate, simultaneously rotating the second fixed disk 53. The second fixed disk 53, via the transmission plate 531, moves the sliding disk 541, which in turn moves the tension rod 521 via the iron disk 523. The tension rod 521 then moves the suction disk 52 inside the suction cylinder 511, transferring the protective oil from the oil tank 511 to the suction cylinder 51 through the oil extraction pipe 512, stretching the second spring 522. As the second fixed disk 53 continues to rotate, the sliding disk 541 separates from the iron disk 523.The second spring 522 slowly draws the protective oil from inside the suction cylinder 511 through the oil outlet pipe 513 into the oiling cylinder 55 via the suction cup 52. As the second fixed plate 53 continues to rotate, the sliding disk 541 re-adheses with the iron plate 523, creating a reciprocating motion. As the wire rope is continuously wound, its surface is coated with oil as it passes through the oiling cylinder 55. Because of the protective oil coating, the wire rope does not cause dry friction against the cylinder 111.
