[0006] Further, the screw rod is completely located in the protection cover, and the length of the protection cover inside is greater than the sum of the length of the screw rod and the length of the screw bush.

[0007] Further, the end close to the screw rod on the connecting rod is fixedly connected with a limiting ring, the diameter of the limiting ring is greater than the diameter of the connecting rod and less than the internal diameter of the protection cover.

[0008] Further, the end close to the connecting rod of the protection cover is provided with a sealing ring.

[0009] Further, the opposite sides of the protection cover outside are provided with handles for easy operation.

[0010] Further, the opposite sides of the protection cover outside are fixedly connected with U-shaped blocks, the U-shaped blocks are fixedly connected with latches, and the handles are rotationally connected with the latches.

[0011] The beneficial effect is that: the utility model discloses a protective cover is set up, and the tightness of cable body is adjusted, and the corrosion of the thread part of screw rod and screw sleeve is prevented effectively by external environment, and the lubricating oil is injected into the inside of screw sleeve through oil inlet pipe, and the lubricating oil is evenly distributed on the contact surface of screw rod and screw sleeve, so that the smoothness of adjustment is improved.

[0016] The technical scheme of the utility model is further explained below in combination with the drawings.

[0017] Please refer to Figs. 1-3 A kind of shore-based crane windproof cable structure, including cable body 1, connection head 2 and protective cover 3, one end of cable body 1 is fixedly connected with protective cover 3, the end close to cable body 1 in protective cover 3 is fixedly connected with screw sleeve 4 inside, the other end of protective cover 3 is slidably connected with connecting rod 5, the end close to screw sleeve 4 of connecting rod 5 is fixedly connected with screw rod 6, screw rod 6 is threadedly connected with screw sleeve 4, the other end of connecting rod 5 is fixedly connected with connection head 2, screw rod 6 is completely located inside protective cover 3, the length inside protective cover 3 is greater than the sum of the length of screw rod 6 and screw sleeve 4, oil inlet hole is formed in the side wall of protective cover 3 and screw sleeve 4, and oil inlet pipe 7 is connected between the oil inlet hole of protective cover 3 and screw sleeve 4.

[0018] Limiting ring 8 is fixedly connected to the end close to screw rod 6 of connecting rod 5, the diameter of limiting ring 8 is greater than the diameter of connecting rod 5 and less than the internal diameter of protective cover 3, limiting ring 8 can limit the movement range of connecting rod 5 in protective cover 3, and simultaneously prevent connecting rod 5 from falling off.

[0019] Sealing ring 9 is arranged on the end close to connecting rod 5 of protective cover 3, sealing ring 9 can improve the sealing property of protective cover 3, and prevent external moisture and dust from entering.
