Description

Technical Field

[0001] The utility model belongs to the technical field of winch equipment, in particular to a winch structure used for marine engineering. Background Art

[0002] The winch structure used in marine engineering usually includes a drum part (including the drum body, flange, etc., used for orderly winding and releasing of wire rope), a drive part (powered by an electric motor, reduced speed and increased torque through a reducer, and cooperated with brakes to ensure safe operation), a wire rope part (including high-strength and corrosion-resistant wire rope and guide wheels to guide the direction), a control system (the operating console and the electrical control system work together to operate and monitor the winch), and a frame and base (the frame supports and fixes the various components, and the base transfers the weight and load to the foundation) to adapt to the harsh environment of the ocean such as high humidity, high salinity, and strong corrosion. It is used for lifting, traction, and positioning operations in offshore drilling platforms, ships and other fields.

[0003] Existing winch devices usually face a more prominent problem during use. Since the winch is often installed in a fixed manner at a specific position, such as by welding or using a large number of fastening bolts to firmly fix it to a base or support structure at a certain place, in such a case, once the winch is damaged during long-term operation, or needs to be fully inspected after a period of use, it will encounter great inconvenience. The reason is that this fixed installation position and method makes it difficult for workers to directly and conveniently access the various key parts and components of the winch. Therefore, additional climbing tools are needed. When working with these climbing tools, the working space will be restricted, which in turn reduces the efficiency of the maintenance work.

[0027] See also Figure 1-5 As shown, the utility model is a winch structure for marine engineering, comprising a support frame 1 and a lifting mechanism 2 and a configuration mechanism 3 provided on the support frame 1;

[0028] The lifting mechanism 2 includes a motor 21 fixedly connected to the right side of the support frame 1, and the output end of the motor 21 is fixedly connected to a bidirectional threaded rod 22, which passes through the support frame 1 and is rotatably connected to the support frame 1. Two sliders 23 are threadedly sleeved on the outer wall of the bidirectional threaded rod 22, and the two sliders 23 are hinged with a connecting rod 24. The left and right inner walls of the support frame 1 are provided with a slide groove 25, and the inner walls of the two slide grooves 25 are slidably connected with a slide plate 26. The top of the slide plate 26 is fixedly connected to two fixed frames 27, and the ends of the two connecting rods 24 away from the slide plate 23 are hinged to the two fixed frames 27.

[0029] The configuration mechanism 3 includes two rectangular plates 31 fixedly connected to the bottom of the slide 26, and a motor 2 32 is fixedly connected to the right side of the corresponding rectangular plate 31. The output end of the motor 2 32 is fixedly connected to a rotating shaft 1 33. The rotating shaft 1 33 passes through the two rectangular plates 31 and is rotatably connected to the two rectangular plates 31. A winding roller 34 is fixedly sleeved on the outer wall of the rotating shaft 1 33, and a steel wire rope 35 is wound around the outer wall of the winding roller 34.

[0030] By starting the motor 2 32, the motor 2 32 will drive the rotating shaft 1 33, the winding roller 34 and the pulley 38 to rotate synchronously. At the same time, when the winding roller 34 rotates, it will cooperate with the guide roller 1 394 and the guide roller 2 396 to reel in the wire rope 35.

[0031] A second rotating shaft 36 is rotatably connected to one side of the two rectangular plates 31 that are close to each other. The left end of the second rotating shaft 36 extends to the outside of the corresponding rectangular plate 31 and is rotatably connected to the corresponding rectangular plate 31. A groove pulley 37 is fixedly provided on the outer wall of the second rotating shaft 36. Pulleys 38 are fixedly provided on the outer walls of both the first rotating shaft 33 and the second rotating shaft 36. Belts 39 are wrapped around the outer walls of the two pulleys 38.

[0032] During the winding process of the steel wire rope 35 , the pulley 38 cooperates with another pulley 38 and the belt 39 so that the second rotating shaft 36 can rotate synchronously with the first rotating shaft 33 .

[0033] A slide rod 391 is fixedly connected to one side of the two rectangular plates 31 that are close to each other. A rectangular frame 392 is slidingly sleeved on the outer wall of the slide rod 391. A slider 2 393 is fixedly connected to the top of the rectangular frame 392. The slider 2 393 is adapted to the groove wheel 37.

[0034] When the rotating shaft 2 36 rotates, it will drive the groove wheel 37 thereon to cooperate with the slider 2 393 on the rectangular frame 392, so that the rectangular frame 392 can drive the guide roller 1 394 and the guide roller 2 396 thereon to move left and right, thereby evenly winding the wire rope 35 during the winding process and preventing the wire rope 35 from winding in one place.

[0035] The inner wall of the rectangular frame 392 is rotatably connected to a guide roller 1 394, and a slide groove 2 395 is provided on the left and right sides of the rectangular frame 392. The inner walls of the two slide grooves 2 395 are slidably connected to a guide roller 2 396, and the left and right ends of the guide roller 2 396 extend outside the two slide grooves 2 395 and are slidably connected to the two slide grooves 2 395.

[0036] During the process of winding up the wire rope 35 by means of guide roller 1 394 and guide roller 2 396 , guide roller 2 396 cooperates with the two rotating blocks 397 so that the spring 398 can apply a downward pushing force to guide roller 2 396 .

[0037] The outer wall of the guide roller 396 is rotatably sleeved with two rotating blocks 397 , and the left and right sides of the rectangular frame 392 are rotatably connected to the rotating blocks 397 , and the sides of several rotating blocks 397 close to each other are fixedly connected with two springs 398 .

[0038] By cooperating with the guide roller 2 396 and the guide roller 1 394 , the wire rope 35 has a certain tension when being wound, ensuring a more ideal winding effect and avoiding problems such as looseness.

[0039] The bottom of the support frame 1 is fixedly connected to a bottom plate 399 .

[0040] The bottom plate 399 supports the support frame 1, allowing it to be securely placed on the ground or other flat surfaces, providing a solid and reliable foundation for the entire device. The bottom plate 399, through its connection to the support frame 1 and its own structural stability, can withstand various external forces or vibrations generated by equipment operation.

[0041] A specific application of this embodiment is: during use, when the winch device needs to be repaired, the motor 1 21 can be started. After the motor 1 21 is started, it will drive the two-way threaded rod 22 to rotate. At the same time, during the rotation of the two-way threaded rod 22, it will drive the two sliders 1 23 thereon to approach each other. Moreover, when the two sliders 1 23 approach each other, they will rotate to cooperate with the two connecting rods 24 and the two fixed frames 27. In this way, the slide 26 at the bottom of the two fixed frames 27 can drive the winch device thereon to slide downward in the slide groove 1 25. Through this arrangement, the winch can be easily repaired, thereby reducing the situation where the maintenance efficiency is reduced due to the need to use additional climbing tools; when the wire rope 35 needs to be reeled in, the motor 2 32 can be started. After the motor 2 32 is started, it will drive the rotating shaft 1 33, the reeling roller 34 and the pulley 38 to rotate synchronously. At the same time, when the reeling roller 34 rotates, it will cooperate with the guide roller 1 394 and the guide roller 2 39 6 pairs of steel wire ropes 35 are wound up, and in the process of winding up the steel wire rope 35, the pulley 38 will cooperate with another pulley 38 and the belt 39 to make the second shaft 36 rotate synchronously with the first shaft 33. At the same time, when the second shaft 36 rotates, it will drive the groove wheel 37 thereon to cooperate with the second slider 393 on the rectangular frame 392. In this way, the rectangular frame 392 can drive the guide roller 1 394 and the guide roller 2 396 thereon to move left and right, thereby adjusting the steel wire rope 35 to the desired direction. The wire rope 35 is evenly wound to prevent the wire rope 35 from being wound in one place; at the same time, in the process of using guide roller 1 394 and guide roller 2 396 to cooperate with the wire rope 35 to wind up, guide roller 2 396 will cooperate with the two rotating blocks 397, so that the spring 398 can apply a downward pushing force to guide roller 2 396, and cooperate with guide roller 1 394 to allow the wire rope 35 to have a certain tension when winding, ensuring a more ideal winding effect and avoiding problems such as looseness.
