Description

Technical Field

[0001] This utility model relates to the field of deep-sea winches, and more particularly to a winch thin-walled drum with gradually thinning reinforcing ribs. Background Technology

[0002] Deep-sea winches, as part of marine scientific research equipment, are commonly used on research vessels for deep-sea geological sampling and seabed biological trawling. As marine scientific research moves to the open ocean and research vessels operate at increasingly deeper depths, the load on their winch systems also increases. However, the winch drums still suffer from insufficient load capacity and excessive weight.

[0003] The drum is the main load-bearing component of a winch, its function being to wind the traction wire rope. Due to the compression from the wire rope during use, the stress in the middle of the drum increases. For drums with insufficient structural strength, this can easily lead to dangerous accidents and is extremely unsafe. Furthermore, research vessels have limited deck space and load-bearing capacity, making it impossible to load winches that are too large or too heavy. Therefore, designing a thin-walled winch drum with gradually thinning reinforcing ribs that meets both strength and lightweight requirements, ensuring safe and stable operation, and protecting life and property, has become a pressing issue. Utility Model Content

[0004] To address the aforementioned technical problems, a winch thin-walled drum with gradually thinning reinforcing ribs is provided. Considering the increased stress in the middle section of the drum due to cable compression during use, reinforcing ribs with rib thickness adapting to the stress distribution are added inside the thin-walled drum, ensuring safe and stable operation. The gradually changing rib thickness and trapezoidal perforation save material and reduce weight while maintaining structural strength. The technical means employed in this invention are as follows:

[0005] A winch thin-walled drum with gradually thinning reinforcing ribs includes a drum body, the inside of which is provided with a plurality of reinforcing ribs. Each reinforcing rib includes a hollow support shaft and a plurality of ribs uniformly mounted circumferentially on the hollow support shaft. The thickness of each rib gradually decreases from the middle to both ends along the length of the hollow support shaft. Weight reduction holes are provided at predetermined positions on the ribs.

[0006] Furthermore, a left flange and a right flange are provided on both sides of the drum body.

[0007] Furthermore, both the left and right flanges are provided with reinforcing rib structures, which are located between the inner wall of the flange and the outer wall of the drum body.

[0008] Furthermore, the reinforcing rib is disposed in the middle section inside the drum body, and a shaft head and a bushing are respectively disposed at both ends of the reinforcing rib. The end of the bushing is flush with the left flange of the drum body, and the end of the shaft head protrudes from the right flange by a certain height.

[0009] Furthermore, the shape of the perforated hole is trapezoidal.

[0010] Furthermore, the two parallel sides of the perforated trapezoid have the shorter side facing the middle and the longer side facing the flange end.

[0011] This invention has the following advantages: It features a simple structure. Taking into account the increased stress in the middle of the drum due to cable compression during use, reinforcing ribs with rib thickness adapted to the stress distribution are added inside the thin-walled drum, ensuring safe and stable operation. The gradual change in rib thickness and trapezoidal perforation save materials and reduce weight while maintaining structural strength. It meets both the strength and lightweight requirements of winch drums, ensuring safe and stable operation and protecting life and property. Attached Figure Description

[0019] like Figures 1-4 As shown in the figure, this utility model discloses a winch thin-walled drum with gradually thinning reinforcing ribs, including a drum body 1. The drum body has several reinforcing ribs 2 inside. Each reinforcing rib includes a hollow support shaft 8 and several ribs 7 evenly mounted circumferentially on the hollow support shaft. In this embodiment, the thickness of the ribs varies with the stress distribution of the drum. Each rib gradually thins from its center to both ends along the length of the hollow support shaft 8. Weight-reducing holes are provided at predetermined positions on the ribs. In this embodiment, the number of ribs is 8. In other optional embodiments, the number of ribs can be adjusted according to the actual application scenario.

[0020] Furthermore, a left flange 3 and a right flange 6 are provided on both sides of the drum body. The left flange 3 and the right flange 6 are connected to the drum body by welding. The shaft head 4 and the bushing 5 are fixedly connected to the drum body. The shaft head 4 is used to drive the drum to rotate, and of course, a motor is connected to its input end as a power source.

[0021] Furthermore, both the left and right flanges are provided with reinforcing rib structures, which are located between the inner wall of the flange and the outer wall of the drum body.
