A marine winch used for hydrological surveys

Abstract

This invention relates to the field of winch technology, specifically disclosing a marine winch for hydrological surveys. The winch includes a base, with a drum rotatably connected inside the base. A cable is wound around the outer surface of the drum. A tensioning assembly is connected to the outer surface of a slide table, which is slidably connected to the base via a linear motor. The tensioning assembly includes a damping wheel and a clamping wheel. The cable passes through the annular outer surfaces of the damping wheel and the clamping wheel, and is clamped by them. The cable is tightened when the drum winds up the cable. By setting up the tensioning assembly, with the cooperation of the drive wheel and the damping wheel, a speed difference exists between the damping wheel and the drive wheel after the cable contacts. Through the damping part, the damping wheel with the speed difference has a certain resistance, which tightens the cable and prevents cable misalignment. Simultaneously, the design of the drive wheel and drive motor ensures that the cable receives sufficient traction during both winding and unwinding phases to maintain its tautness, and the magnitude of the traction force can be adjusted by the drive motor.

Description

Technical Field

[0001] This invention relates to the field of winch technology, specifically to a marine winch used for hydrological surveys. Background Technology

[0002] Marine winches are small, lightweight lifting devices that use a drum to wind steel wire rope or chain to lift or pull heavy objects; they are also known as hoists. Winches are installed on ships and can be used independently or as components in lifting and hoisting machinery. They are widely used due to their simple operation, large rope capacity, and ease of relocation.

[0003] Existing winches are installed on the hull, and the installation is usually simple. Although the cable can be guided to the outer surface of the drum by the guide mechanism, since the carrier is a ship, the ship will rise and fall in the sea and other undulating areas, which will cause the cable to become slack. This will affect the cable winding and traction, and thus make it impossible for the ship to operate in areas with waves.

[0004] Therefore, we propose a ship winch for hydrological surveys. Summary of the Invention

[0005] The purpose of this invention is to provide a marine winch for hydrological surveys to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a marine winch for hydrological surveys, comprising a base, wherein a drum is rotatably connected inside the base, and a cable is wound around the outer surface of the drum;

[0007] The tensioning assembly is connected to the outer surface of the slide table, which is slidably connected to the base via a linear motor. The tensioning assembly includes a damping wheel and a pressure wheel. The cable passes through the annular outer surfaces of the damping wheel and the pressure wheel, and is clamped by the damping wheel and the pressure wheel, thus tightening the cable when the drum winds up the cable.

[0008] The cleaning section is located inside the damping wheel and the clamping wheel. As the cable is wound up, the cleaning fluid washes the cable along the annular outer surface of the clamping wheel and the damping wheel.

[0009] The damping wheel has a ring structure design. A drive wheel is rotatably connected to the center of the damping wheel via a bearing. One side of the drive wheel is driven by a drive motor, which is fixedly connected to the surface of the slide. The other side of the drive wheel is rotatably connected to a damping part via a rotating shaft. The end of the damping part away from the drive wheel pair is rotatably connected to the outer surface of the damping wheel.

[0010] The damping part includes a telescopic cylinder. One end of the telescopic cylinder is rotatably connected to the outer surface of the damping wheel via a rotating shaft. A piston is slidably connected inside the telescopic cylinder. A telescopic rod is fixedly connected to the lower outer surface of the piston. The telescopic rod and the telescopic cylinder are kept sealed. The end of the telescopic rod away from the telescopic cylinder is rotatably connected to the outer surface of the drive wheel. A damping hole is formed through the surface of the piston.

[0011] The drive wheel has a hollow interior and an outlet hole on its annular outer surface. A connecting pipe is fixedly connected to the outer surface of the drive wheel away from the damping part. An infusion hole is provided on the annular outer surface of the connecting pipe. A rotating ring is rotatably connected to the annular outer surface of the connecting pipe via a bearing. A tube for delivering cleaning fluid is inserted into the annular outer surface of the rotating ring. The damping wheel has a cavity inside, and a leakage hole is provided through the annular inner surface of the cavity.

[0012] The pressure roller has a cavity two inside, and the annular inner surface of the cavity two has a leakage hole two through it.

[0013] Inside the cavity, a counterweight is rotatably connected via a bearing. There are two sets of counterweights, with an outer ring and an inner ring fixedly connected between the two sets. The outer ring fits against the inner annular surface of the cavity, and the inner ring fits against the outer annular surface of the drive wheel. There is a space between the two sets of counterweights, which is aligned with the cable.

[0014] Inside the cavity two, a counterweight two is rotatably connected via bearings. A retaining ring is fixedly connected to both ends of the counterweight two. The retaining ring is in contact with the annular inner surface of the cavity two. A partition is fixedly connected to the middle of the retaining ring.

[0015] The clamping wheel is rotatably connected to a connecting block via a rotating shaft on the side away from the drive motor. A spring rod is fixedly connected to the lower outer surface of the connecting block, and the lower end of the spring rod is fixedly connected to the slide table.

[0016] The base has a sliding rod fixedly connected to the outer surface of the base at a position corresponding to the drum. A sliding sleeve is slidably connected to the outer surface of the sliding rod. A contact roller is rotatably connected to the end of the sliding sleeve away from the sliding rod via a rotating shaft. A controller is fixedly connected to the upper outer surface of the sliding rod. A conductive sheet is fixedly connected to the outer surface of the sliding rod. A conductive block is fixedly connected to the sliding sleeve at a position corresponding to the conductive sheet. The controller is connected to the upper outer surface of the base and is electrically connected to the drive motor.

[0017] The present invention has at least the following beneficial effects:

[0018] By setting up a tensioning component, with the cooperation of the drive wheel and the damping wheel, a speed difference exists between the damping wheel and the drive wheel after the cable comes into contact. Through the damping part, the damping wheel with the speed difference has a certain resistance, which tightens the cable and prevents the cable from misaligning. At the same time, the design of the drive wheel and drive motor ensures that the cable can receive sufficient traction force during the winding and release phases to keep the cable taut and prevent the cable from becoming loose and misaligned. The magnitude of the traction force can be adjusted by the drive motor.

[0019] By opening two drainage holes inside the damping wheel and the clamping wheel, the cleaning fluid can be flushed through the channels formed by the various stages to effectively clean and maintain the cable, reducing the time required for maintenance. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-12 The present invention provides a technical solution: a marine winch for hydrological surveys, comprising a base 1, wherein a drum 10 is rotatably connected inside the base 1, and a cable 11 is wound around the outer surface of the drum 10.

[0035] Tensioning assembly 2 is connected to the outer surface of slide table 24. Slide table 24 is slidably connected to base 1 via linear motor 12. Tensioning assembly 2 includes damping wheel 20 and pressure wheel 21. Cable 11 passes through the annular outer surface of damping wheel 20 and pressure wheel 21. The damping wheel 20 and pressure wheel 21 clamp cable 11. When drum 10 winds up cable 11, it tightens cable 11, ensuring that cable 11 remains taut even when facing the undulation of the boat. This more effectively winds up cable 11, prevents cable 11 from misaligning, meets the usage requirements under undulating conditions, and is more suitable for boats.

[0036] The cleaning section 5 is located inside the damping wheel 20 and the clamping wheel 21. As the cable 11 is wound up, the cleaning fluid will rinse the cable 11 along the annular outer surface of the clamping wheel 21 and the damping wheel 20, thus cleaning the cable 11 and reducing the corrosion of the cable 11 by seawater.

[0037] The damping wheel 20 has a ring structure design. The center of the damping wheel 20 is rotatably connected to the drive wheel 27 via a bearing. One side of the drive wheel 27 is driven by the drive motor 25, which is fixedly connected to the surface of the slide table 24. The slide table 24 drives the entire tensioning assembly 2 to move in the winding direction of the cable 11, ensuring that the cable 11 is tightly wound. The other side of the drive wheel 27 is rotatably connected to the damping part 28 via a rotating shaft. The end of the damping part 28 away from the drive wheel 27 is rotatably connected to the outer surface of the damping wheel 20. The damping part 28 generates resistance between the damping wheel 20 and the drive wheel 27 during rotation, and the cable 11 is always taut under the action of the speed difference.

[0038] The damping part 28 includes a telescopic cylinder 30. One end of the telescopic cylinder 30 is rotatably connected to the outer surface of the damping wheel 20 via a rotating shaft. A piston 31 is slidably connected inside the telescopic cylinder 30. A telescopic rod 29 is fixedly connected to the lower outer surface of the piston 31, and the telescopic rod 29 and the telescopic cylinder 30 are kept sealed. The end of the telescopic rod 29 away from the telescopic cylinder 30 is rotatably connected to the outer surface of the drive wheel 27. A damping hole 26 is formed through the surface of the piston 31, and the inside is filled with damping fluid. When the drive wheel... When motor 25 drives drive wheel 27 to rotate, damping wheel 20 rotates synchronously due to the presence of damping part 28. Simultaneously, it is subjected to the frictional force of cable 11, forcing damping part 28 to exhibit deceleration characteristics, resulting in a speed difference for damping wheel 20. When drum 10 rotates clockwise to begin winding cable 11, drive motor 25 controls drive wheel 27 to rotate in the opposite direction. Since drive wheel 27 and damping wheel 20 are rotatably connected via bearings, the frictional force between damping wheel 20 and cable 11 keeps the winding speed of cable 11 consistent. The damping section 28 functions, forcing the damping wheel 20 to have a force that hinders the winding of the cable 11, but is less than the traction force of the drum 10, thus ensuring that the cable 11 remains taut for this distance. When the drum 10 begins to rotate counterclockwise to release the wound cable 11, the drive motor 25 controls the drive wheel 27 to rotate in the same direction, but at a speed greater than that of the drum 10, forcing a speed difference between the damping wheel 20 and the drive wheel 27. This increases the resistance of the damping wheel 20 to the cable 11 through the damping section 28. The traction force ensures that the cable 11 remains taut during the release phase. The reciprocating motion of the telescopic rod 29 inside the telescopic cylinder 30 generates resistance, causing the drive wheel 27 and the damping wheel 20 to produce a speed difference with traction force. At the same time, the telescopic cylinder 30 and the telescopic rod 29 rotate around their respective rotation connection points as the midpoint, resulting in an overall irregular rotation. Through the design of the above technical solution, the winch can still effectively reel in the cable 11 even when the ship is in a state of slight undulation, increasing the stability of the cable 11 reeling.

[0039] The drive wheel 27 has a hollow interior. A liquid outlet 32 ​​is provided on the annular outer surface of the drive wheel 27. A connecting pipe 52 is fixedly connected to the side of the outer surface of the drive wheel 27 away from the damping part 28. One end of the connecting pipe 52 is fixedly connected to the output end of the drive motor 25. A filling hole 54 is provided on the annular outer surface of the connecting pipe 52. A rotating ring 53 is rotatably connected to the annular outer surface of the connecting pipe 52 via a bearing. A tube 51 for delivering cleaning fluid is inserted into the annular outer surface of the rotating ring 53. A cavity 37 is provided inside the damping wheel 20. A drain hole 33 is provided through the annular inner surface of the cavity 37. The cleaning fluid enters the connecting pipe 52 through the tube 51, then enters the drive wheel 27, enters the cavity 37 through the liquid outlet 32, and is discharged through the drain hole 33 to rinse the cable 11. This structure allows water to be supplied to the cavity 37 while the damping wheel 20 and the drive wheel 27 are rotating.

[0040] The pressure wheel 21 has a cavity 39 inside, and a drain hole 41 is provided through the annular inner surface of the cavity 39. One side of the pressure wheel 21 has the same water supply structure as the drive wheel 27, which can ensure that water is supplied to the cavity 39 while rotating, and the cable 11 is rinsed on both the upper and lower sides to improve the cleaning effect.

[0041] Inside the cavity 37, counterweights 34 are rotatably connected via bearings. There are two sets of counterweights 34, with an outer ring 35 and an inner ring 36 fixedly connected between them. The outer ring 35 fits against the inner annular surface of the cavity 37, and the inner ring 36 fits against the outer annular surface of the drive wheel 27. The inner ring 36 and the outer annular surface of the drive wheel 27 are rotatably connected via a sealed bearing, and the outer ring 35 and the inner annular surface of the cavity 37 are rotatably connected via a sealed bearing. There is space between the two sets of counterweights 34, which is aligned with the cable 11. Through the symmetrical design of the two counterweights 34, a downward channel is formed between them. Under the obstruction of the inner ring 36 and the outer ring 35, the cleaning liquid can only move downward along the channel formed by the counterweights 34, increasing the impact pressure of the liquid and reducing the waste of cleaning liquid, thus further improving the cleaning effect. The design of the counterweights 34 ensures that the formed channel is always vertically downward to rinse the cable 11.

[0042] Inside the cavity 39, a counterweight 43 is rotatably connected via bearings. Retaining rings 44 are fixedly connected to both ends of the counterweight 43. The retaining rings 44 fit against the annular inner surface of the cavity 39 and are also rotatably connected to it via sealed bearings. A partition 42 is fixedly connected to the middle of the retaining ring 44, forming a channel between the partition 42 and the counterweight 43. This channel ensures that the cleaning fluid entering the cavity 39 moves vertically upwards, passing through the drain hole 41 to rinse the bottom of the cable 11. The design of the counterweight 43 ensures that the channel remains vertically upwards at all times. A sleeve 50 is fitted onto the outer surface of the insertion tube 51 to prevent the insertion tube 51 from falling off during the vertical displacement of the pressure wheel 21. A water supply hose 55 is fixedly connected to the outer surface of the sleeve 50, and a high-pressure pump is connected to the end of the hose 55.

[0043] The side of the clamping wheel 21 away from the drive motor 25 is rotatably connected to the connecting block 22 via a rotating shaft. A spring rod 23 is fixedly connected to the lower outer surface of the connecting block 22. The lower end of the spring rod 23 is fixedly connected to the slide table 24. The spring rod 23 pushes the connecting block 22 and the clamping wheel 21 to press against the outer surface of the cable 11, providing sufficient friction for the damping wheel 20 and the clamping wheel 21, and increasing the stability of the structure.

[0044] A slide rod 61 is fixedly connected to the outer surface of the base 1 at a position corresponding to the drum 10. A sliding sleeve 62 is slidably connected to the outer surface of the slide rod 61. A contact roller 65 is rotatably connected to the end of the sliding sleeve 62 away from the slide rod 61 via a rotating shaft. A controller 60 is fixedly connected to the upper outer surface of the slide rod 61. A conductive sheet 63 is fixedly connected to the outer surface of the slide rod 61. A conductive block 64 is fixedly connected to the sliding sleeve 62 at a position corresponding to the conductive sheet 63. The controller 60 is connected to the upper outer surface of the base 1 and electrically connected to the drive motor 25. The cable 11 wound on the surface of the drum 10 will gradually thicken. At this time, as the thickness of the cable 11 wound around the outside of the drum 10 increases, the linear speed gradually increases. At this time, it is necessary to gradually reduce the speed of the drive motor 25. The conductive sheet 63 contacts the conductive block 64 and transmits the electrical signal to the controller 60, which then controls the speed of the drive motor 25.
