Description

Technical Field

[0001] This utility model relates to the field of underwater winches, and in particular to a winch. Background Technology

[0002] Underwater winches are commonly used in marine engineering, underwater exploration, and salvage operations to deploy and retrieve cables or wires. The cables are equipped with knots that serve several key functions: load securing: firmly connecting underwater equipment (detectors, robotic arms, samplers, etc.) to the winch cable to prevent detachment under high pressure or water flow impact; anti-slip design: using the frictional structure of special knots to prevent the cable from loosening due to uneven stress or swaying, thus avoiding equipment loss; stress dispersion: knots evenly distribute localized tension on the cable, reducing the risk of breakage due to sudden impacts (such as equipment collisions or waves); cushioning protection: some knots can absorb vibration energy, protecting the winch motor and the internal fiber structure of the cable; emergency release: slipknots or untieable knots allow for rapid disconnection in case of equipment jamming or sudden danger, ensuring the safety of personnel and equipment.

[0003] During deep-sea exploration, underwater winches lay cables at a speed of 0.1-0.3 m / s and retrieve cables at a speed of 0.25 m / s. This low speed ensures accurate positioning and stability of the equipment. When laying cables in the deep sea, due to the presence of knots, a clearance gap is required at the upper end of the cable laying mechanism. When laying and retrieving cables, the operator needs to manually move the knot upwards to allow it to pass through the clearance gap, thus facilitating its removal.

[0004] However, when the cable is being laid out, it is easy for the operator to lay it out because the cable is clean. The speed at which the cable is laid out will not cause injury to the operator. However, when the cable is being retrieved, the cable has been soaked in the seabed for a long time and is covered with seawater and seabed products. If the operator is still nearby when the cable is being retrieved, it is easy for the operator to be splashed with seawater or hit by seabed products. Utility Model Content

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings.

[0036] A type of winch, such as Figures 1-5 As shown, the device includes a frame 1, a drum 2, a drive assembly 3, and a rope arranger 4. The drum 2 is rotatably connected to the top of the frame 1. The rope arranger 4 is located on the front side of the top of the frame 1 and in front of the drum 2. The drive assembly 3 is connected to the drum 2 and the rope arranger 4 respectively. The rope arranger 4 includes a displacement assembly 5 and a cable arrangement assembly 6. The cable arrangement assembly 6 is rotatably connected to the top of the displacement assembly 5 and rotates on the top of the displacement assembly 5.

[0037] The displacement assembly 5 includes two fixed plates 512, a lead screw 513, a guide rod 514, and two sliding plates 515;

[0038] Two fixing plates 512 are respectively fixed on the left and right sides of the top front of the frame 1. A lead screw 513 is rotatably connected to the upper ends of the two fixing plates 512. A guide rod 514 is fixed to the upper ends of the two fixing plates 512 and is located directly below the lead screw 513. A first cylinder 516 and a second cylinder 517 are fixedly arranged horizontally between the two sliding plates 515. A nut seat 518 is provided inside the first cylinder 516. The first cylinder 516 is sleeved on the outside of the lead screw 513, and the second cylinder 517 is sleeved on the outside of the guide rod 514. The lead screw 513 and... The drive assembly 3 is connected to the transmission and drives the lead screw 513 to rotate. Under the action of the guide rod 514, the two sliding plates 515 move left and right through the nut seat 518. The drive assembly 3 consists of a motor, a first gear, and a second gear. The rotating shaft of the motor is fixedly connected to the drum 2. The first gear is sleeved on the rotating shaft of the motor, and the second gear is sleeved on the lead screw 513. A chain meshes on the first gear and the second gear. When the motor rotates, it drives the lead screw 513 and the drum 2 to rotate respectively. This technology is the existing technology of winches and will not be described in detail here.

[0039] The cable assembly 6 includes two support plates 611 placed side by side, a connecting base plate 612, two first rollers 613 placed longitudinally side by side, and a second roller 614 and a third roller 615 placed laterally. The two support plates 611 are placed vertically. The connecting base plate 612 is fixedly located at the lower end between the two support plates 611. The connecting base plate 612 is U-shaped. The two first rollers 613 are respectively rotatably located on the left and right sides between the two support plates 611. The second roller 614 is rotatably connected to the bottom front side of the two support plates 611. The third roller 615 is rotatably connected to the top rear side of the two support plates 611.

[0040] A first rotating plate 616 is fixedly provided at the bottom of the two support plates 611 from the front to the back quarter of the distance. The upper end of the displacement component 5 is located between the two first rotating plates 616. A rotating shaft 519 is fixedly provided at the upper end of the two sliding plates 515. Each rotating shaft 519 is inserted into its corresponding first rotating plate 616, so that the two support plates 611 rotate along the rotating shaft 519.

[0041] Positioning pins 511 are provided on the left and right sides of the upper rear side of the displacement component 5. That is, positioning pins 511 are provided on the upper rear side of both sliding plates 515, and an arc-shaped waist groove 617 is provided on the upper rear side of each first rotating plate 616. Each positioning pin 511 is inserted into its corresponding waist groove 617. The positioning pin 511 slides in the waist groove 617, thereby limiting the rotation angle of the displacement component 5.

[0042] Each first rotating plate 616 is an inverted triangle, and the central angle of each waist-shaped groove 617 is 30°. The center of the circle corresponding to the central angle of each waist-shaped groove 617 is the same as the center of its corresponding rotating shaft 519. When the first rotating plate 616 rotates upward, the angle between it and the horizontal plane is 30°. However, when the first rotating plate 616 is in a horizontal state, it is difficult for it to rotate upward automatically without human intervention. Therefore, a chamfer is provided on the front side of the top of each sliding plate 515. The top of the chamfer abuts against the bottom of the connecting base plate 612. At this time, the initial rotation angle of the first rotating plate 616 with the horizontal plane is limited to 12°. At the same time, due to the existence of the chamfer, it will not be interfered with when it rotates upward, i.e., counterclockwise.

[0043] To ensure unmanned flipping, several counterweights 620 are fixedly provided on the front side of the bottom of the connecting base plate 612. The front side of the counterweights 620 is flush with the front side of the connecting base plate 612. When there is no knot, that is, the first rotating plate 616 is less dragged backward and downward, and under the gravity of the counterweights 620, it automatically flips upward.

[0044] Each support plate 611 has a first square through hole 618 on its right side, both front and rear. A baffle 619 is fixedly inserted into each first square through hole 618. Three-quarters of each baffle 619 is located between two support plates 611. The first roller 613 rotates between the two baffles 619 of its corresponding support plate 611. This baffle 619 insertion configuration ensures that the strength after welding is higher than that of direct welding to a flat surface, thus providing sufficient support for the high-intensity operation of the first roller 613.

[0045] Each support plate 611 is further provided with a second rotating plate 621 on its bottom front side. Each second rotating plate 621 is located between its corresponding counterweight 620 and the first rotating plate 616. A second roller 614 is rotatably connected between the two second rotating plates 621, and the position of the second roller 614 corresponds to the "U"-shaped opening of the connecting base plate 612. During cable laying and winding, the cable passes through the "U"-shaped opening of the connecting base plate 612 and is located at the top of the second roller 614, which facilitates cable laying and winding.

[0046] A third rotating plate 622 is fixedly installed on the top rear side of each support plate 611. Each third rotating plate 622 is located behind the rear baffle 619. A 40mm gap is left between the front side of each third rotating plate 622 and the rear baffle 619. A third roller 615 is rotatably connected between two third rotating plates 622. When there is a knot, the knot passes through the 40mm gap. At this time, the third roller 615 facilitates the winding of the cable.

[0047] Each support plate 611 is fixedly provided with a reinforcing plate 623 on the side away from the first roller 613, and each reinforcing plate 623 is fixedly connected to its corresponding baffle 619.

[0048] Specific implementation process:

[0049] Step 1: The winch is not in operation, and the cable laying assembly 6 is in its initial state, that is, under the action of several counterweights 620, the bottom of the cable laying assembly 6 forms an angle of 30° with the horizontal plane.

[0050] Step 2: The winch lays the cable. At this time, the cable passes the top of the second drum 614 and is discharged through the "U"-shaped opening of the connecting base plate 612.

[0051] Step 3: When laying the cable, if a knot appears, the operator will move the cable upwards to between the third rotating plate 622 and the rear baffle 619. The cable will be discharged through the 40mm gap between the third rotating plate 622 and the rear baffle 619. After the knot is discharged, the cable will continue to fall into the "U"-shaped opening of the connecting base plate 612 and continue laying the cable.

[0052] Step 4: When reeling in the cable, the operator is not near the winch at this time;

[0053] Step 5: The winch winds up the cable. At this time, the cable passes through the "U"-shaped opening of the connecting base plate 612, passes through the top of the second drum 614, and is wound around the winch drum 2.

[0054] Step 6: When a knot appears, it is stuck between the two first rollers 613. The winch continuously tightens the cable, and the knot slides up along the two first rollers 613. At the same time, the cable laying assembly 6 rotates along the rotating shaft 519. When the bottom of the connecting base plate 612 abuts against the top of the chamfer of the sliding plate 515, the angle between the first rotating plate 616 and the horizontal plane is 12°. The knot slides up through the 40mm gap between the third rotating plate 622 and the rear baffle 619.

[0055] Step 7: Under the gravity of several counterweights 620, the rear side of the cable assembly 6 rotates upward to the initial position.

[0056] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
