Description

Technical Field

[0001] The invention relates to the technical field of marine equipment, in particular to a marine winch cable adaptive adjustment device. Background Art

[0002] A marine winch is a small and light lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. It has the characteristics of simple operation, large rope winding capacity, and easy relocation. However, the current marine winch still has some shortcomings.

[0003] A search revealed Chinese patent application number CN101746686B, which discloses an adaptive cable adjustment device for a marine winch. The device comprises a rocker arm with a pulley attached to a pulley shaft at one end. The other end of the rocker arm is rotatably connected to the rocker arm shaft, which is fixed to a bracket. The upper end of a tension spring is fixed to the middle of the rocker arm, and the other end of the tension spring is fixed to a bracket below the lower limit block. The bracket is fixed to the ship's deck 1-2 meters from the marine winch. The rocker arm pulley spans the cable between the winch guide wheel and the gantry pulley. The bracket defines the rocker arm's operating range and is equipped with upper and lower limit blocks, respectively. The distance between the upper and lower limit blocks is within a range of 1.5-2 meters. Clearly, this technology, when used in conjunction with a marine winch, can automatically adjust the tension of the steel cable at any time, ensuring proper cable arrangement for the winch cable arrangement and effectively ensuring the continuity of marine survey data.

[0004] The existing self-adaptive adjustment device for the cable of a marine winch cannot control the cable in emergency situations such as winch brake failure or the cable being slippery and unable to be clamped and fixed, which can easily cause the cable to slip out of control. Directly using external force to forcibly fix the out-of-control cable can easily lead to dangerous situations such as breakage. Therefore, an self-adaptive adjustment device for the cable of a marine winch is proposed to solve the above problems. Summary of the Invention

[0011] Preferably, the overall shape of the clamping arm is arc-shaped, and a corner is provided at the upper end to facilitate the pressing plate to squeeze, and the two groups of clamping arms are symmetrically distributed outside the central axis.

[0012] Preferably, the outer side of the peripheral wiping component is an annular wiping belt, which has water absorption and strong toughness.

[0013] Preferably, the outer side of the inner wiping assembly is an annular wiping belt, which is driven and supported by the inner corner shaft. The inner wiping assembly and the outer wiping assembly wipe the cable from different positions.

[0018] The self-adaptive adjustment device for the marine winch cable wipes the cable by arranging an outer wiping component and an inner wiping component on both sides of the cable so that moisture on the cable surface can be quickly removed. The device removes liquid on the inner sides of the outer wiping component and the inner wiping component by arranging an extrusion mechanism so that the outer wiping component and the inner wiping component can be used continuously to remove moisture from the cable surface, thereby solving the problem of brake failure caused by moisture on the cable surface.

[0033] like Figure 1-9 As shown, a marine winch cable adaptive adjustment device includes a positioning housing 1 and a cable 6, a positioning housing 1, a first linkage component 2 is provided at the lower end of the positioning housing 1, a lower bracket 3 is provided on the surface of the first linkage component 2, a second linkage component 4 is provided at the upper end of the positioning housing 1, an upper bracket 5 is provided on the surface of the second linkage component 4, the first linkage component 2 includes a rotating shaft 21, a sprocket is provided at the upper end of the rotating shaft 21 and a gear is provided at the lower end, the gear of the rotating shaft 21 is meshed with a first threaded shaft 22, the upper end of the first threaded shaft 22 is a threaded rod and is threadedly connected to the lower bracket frame 32, A spur gear is provided at the lower end, and the sprocket of the rotating shaft 21 is meshed with the second threaded shaft 23 through a chain. The upper end of the second threaded shaft 23 is a threaded rod threadedly connected to the lower bracket frame 32, and a sprocket is provided at the lower end. The second linkage component 4 has the same structure as the first linkage component 2 and is symmetrical in the upper and lower directions. The first linkage component 2 rotates the rotating shaft 21 driven by the motor, so that the rotating shaft 21 can simultaneously drive the first threaded shaft 22 and the second threaded shaft 23 on both sides to rotate simultaneously, so that the height of the lower bracket 3 can be adjusted, and the second linkage component 4 can drive the upper bracket 5 to move.

[0034] The upper end of the lower bracket 3 is two groups of arrays of rollers 31, and the two ends of the rollers 31 are connected by the lower bracket frame 32. The upper bracket 5 is composed of three groups of rollers 31 and an upper bracket frame. The lower bracket 3 and the upper bracket 5 cooperate to make the cable 6 wrapped around the outside, which is convenient for stretching the cable 6 and makes it more difficult for the cable 6 to pass through the lower bracket 3 and the upper bracket 5.

[0035] The cable 6 is wound around the surface of the lower bracket 3 and the upper bracket 5. A peripheral wiping component 7 is provided on the inner side of the positioning shell 1. The peripheral wiping component 7 is in contact with the cable 6 and is used to remove water stains on one side of the surface of the cable 6. The outer side of the peripheral wiping component 7 is an annular wiping belt. The annular wiping belt is water-absorbent and has strong toughness. The inner side of the annular wiping belt is supported and driven to rotate by a corner shaft. The annular wiping belt is used to absorb moisture on the outside of the cable 6. The peripheral wiping component 7 contacts the cable 6 and can wipe and absorb moisture on the surface of the cable 6 by utilizing its own water-absorbent properties.

[0036] An inner wiping assembly 8 is provided on the inner side of the positioning shell 1. The inner wiping assembly 8 contacts the cable 6 and is used to clean water stains on the other side of the surface of the cable 6. The outer side of the inner wiping assembly 8 is an annular wiping belt, which is driven and supported by the inner corner shaft. The inner wiping assembly 8 and the outer wiping assembly 7 wipe the cable 6 from different positions. The inner wiping assembly 8 can contact the cable 6 to wipe and absorb moisture on the surface. The inner wiping assembly 8 and the outer wiping assembly 7 wipe the cable 6 on both sides of the cable 6 respectively, so that the cable 6 will not fail to brake due to wetness when braking.

[0037] A squeezing mechanism 9 is provided on the inner side of the positioning shell 1 for squeezing out moisture inside the outer wiping assembly 7 and the inner wiping assembly 8. Water tanks are provided on both sides of the positioning shell 1 for collecting moisture squeezed out by the squeezing mechanism 9. The water tanks are located below the squeezing mechanism 9. There are two groups of squeezing mechanisms 9, one at each end of the outer wiping assembly 7. The squeezing mechanism 9 is composed of a linear array of four circular axes, two of which are located on the inner and outer sides of the outer wiping assembly 7 respectively, and the upper ends of the two circular axes are meshed with gears. The other two circular axes are located on the inner and outer sides of the inner wiping assembly 8, and the upper ends of the two circular axes are meshed with gears. The two in the middle of the four circular axes in the array are connected by gear meshing. The squeezing mechanism 9 squeezes and rolls on the surface of the outer wiping assembly 7 and the inner wiping assembly 8 through the circular axes, so that the moisture absorbed by the outer wiping assembly 7 and the inner wiping assembly 8 can be quickly squeezed out, so that the outer wiping assembly 7 and the inner wiping assembly 8 can continuously and effectively wipe the cable 6.

[0038] The upper end of the positioning shell 1 is provided with a wrapping shell 10, and the upper end of the positioning shell 1 is fixedly provided with a pressing mechanism 11, which is slidably connected to the inner wall of the wrapping shell 10, and a clamping mechanism 12 is provided on the inner side of the wrapping shell 10. The clamping mechanism 12 includes a central axis 121, and the surface of the central axis 121 is rotatably connected to the clamping arm 122. The lower end of the clamping arm 122 is rotatably provided with a clamping shaft, and the clamping mechanism 12 also includes a guide plate 123, which is fixedly connected to the positioning shell 1, and the surface of the guide plate 123 is fixedly connected to the positioning shell 1. An arc-shaped spring shaft is provided, which passes through the clamping arm 122. A reset spring 124 is sleeved on the outside of the spring shaft. The reset spring 124 is on the outside of the clamping arm 122. The clamping mechanism 12 rotates the clamping arm 122 to clamp the cable 6 wound around the lower bracket 3 and the upper bracket 5, so that the wound cable 6 can be squeezed and stacked, thereby increasing the friction of the cable 6 and preventing the cable 6 from slipping and causing brake failure. By setting the reset spring 124, the clamping arm 122 can be pushed to reset in time.

[0039] The overall shape of the clamping arm 122 is arc-shaped, and a corner is provided at the upper end to facilitate the squeezing of the pressing plate 113. The two sets of clamping arms 122 are symmetrically distributed on the outside of the central axis 121. The clamping arm 122 can push the wound cable 6 to squeeze and overlap by rotating. By providing a rotatable clamping shaft, the cable 6 can still move when the cable 6 is clamped, preventing the cable 6 from breaking due to locking.

[0040] The pressing mechanism 11 includes a support frame 111, a hydraulic telescopic rod 112 is fixedly connected to the inner side of the upper end of the support frame 111, and a pressing plate 113 is fixedly connected to the free end of the hydraulic telescopic rod 112. The lower surface of the pressing plate 113 is in compression contact with the clamping arm 122. The pressing mechanism 11 can drive the pressing plate 113 through the hydraulic telescopic rod 112, so that the pressing plate 113 squeezes the clamping arm 122, thereby providing power for the clamping arm 122 to clamp the cable 6.

[0041] When the upper and lower frames are in the state of being lifted up, the upper and lower frames 5 are in the state of being lifted up, and the lower and upper frames 5 are in the state of being lifted up. The cable 6 on the surface of the bracket 5 is clamped to increase the friction of the cable 6, so that the cable 6 will not continue to pass through the lower bracket 3 and the upper bracket 5, thereby achieving the purpose of braking. When the surface of the cable 6 is more moist during use, the outer wiping component 7 and the inner wiping component 8 are driven by the starting motor, so that the outer wiping component 7 and the inner wiping component 8 rotate and pass through the positioning shell 1, so that the outer wiping component 7 and the inner wiping component 8 contact the cable 6, and the moisture on the surface of the cable 6 is absorbed through the contact between the outer wiping component 7 and the inner wiping component 8. The extrusion mechanism 9 is driven by the starting motor so that the circular axis of the extrusion mechanism 9 rotates and squeezes on the outside of the outer wiping component 7 and the inner wiping component 8 respectively, so that the moisture absorbed by the outer wiping component 7 and the inner wiping component 8 can be squeezed out and collected, so that the outer wiping component 7 and the inner wiping component 8 can continuously wipe the cable 6, and the problem of excessive moisture on the surface of the cable 6 causing the inability to brake is eliminated.
