A ship mooring machine sheath

Abstract

A ship mooring machine sheath belongs to the technical field of mooring machine limit protection. It is designed to solve the problem of left-right sliding on the middle shaft of the mooring machine after long-term use, displacement during rotation, and wear of other auxiliary structures. The present application combines the upper and lower discs on the middle shaft of the mooring machine frame, and then rotates the threaded rod through a tool. The threaded rod drives the sliding half to slide in the limit groove through the threaded groove on the sliding half. The sliding half drives the extrusion rotating rod, and the rotating rod extrudes and pushes the connecting block. The rotating rod rotates in the rotating groove, and the connecting block pushes the two upper and lower discs apart. The slider slides in the sliding groove, and the slider drives the positioning plate to slide in the positioning groove, so that the upper and lower discs cannot be separated, making the overall thickness of the equipment thicker. The thickness of the limit sheath can be adjusted to prevent the cable drum from sliding on the middle shaft after long-term use of the mooring machine, displacement, and wear of the structure on the mooring machine.

The first semi-circular hole 32 and the second semi-circular hole 42 on the upper semi-disc 3 and the lower semi-circular hole 4 form a complete circular hole. The upper semi-disc 3 and the lower semi-disc 4 are clamped on the intermediate shaft on the cable winch frame 1 through the circular holes. The positioning rod 41 is inserted into the positioning slot 31 so that the upper semi-disc 3 and the lower semi-disc 4 can be docked without misalignment. The upper semi-disc 3 and the lower semi-disc 4 are connected together by inserting bolts into the bolt grooves 7.

[0022] The utility model is further described below in conjunction with embodiments.

[0023] Embodiment 1:

[0024] Combination Figure 5 In this embodiment, a semicircular through hole 5 is provided on one side of the upper semicircular disk 3 and the lower semicircular disk 4 respectively, a semicircular groove 51 is provided on one side of the upper semicircular disk 3 and the lower semicircular disk 4, a limiting groove 52 is provided on one side of the upper semicircular disk 3 and the lower semicircular disk 4, a sliding groove 53 is provided on one side of the upper semicircular disk 3 and the lower semicircular disk 4, positioning grooves 54 are provided on both sides of the sliding groove 53, and the semicircular groove 51 is connected with the limiting groove 52 and the sliding groove 53.

[0025] Furthermore, when the two upper semicircular disks 3 are attached together, the semicircular through hole 5 forms a circular through hole; and the semicircular groove 51 forms a round rod groove.

[0026] Furthermore, a threaded rod 6 is arranged in the circular through hole formed by the two semicircular through holes 5, a sliding block 61 is arranged on the outside of the threaded rod 6, a rotating groove 62 is arranged below the sliding block 61, and there are two rotating grooves 62, a rotating rod 63 is connected to the rotating groove 62, two connecting blocks 64 are fixedly connected to one side of the inner part of the limiting groove 52, a sliding block 65 is slidably connected in the sliding groove 53, four positioning plates 66 are arranged on both sides of the sliding block 65, and the limiting groove 52 limits the sliding block 61 to prevent the sliding block from rotating.

[0027] Furthermore, a threaded hole is provided on the sliding block 61, the sliding block 61 is slidably connected in the limiting groove 52, the threaded rod 6 is rotatably connected to the slider 65, the threaded rod 6 is arranged between the two semicircular through holes 5 and the two semicircular grooves 51, the other end of the rotating rod 63 is rotatably connected between the two connecting blocks 64, and the positioning plate 66 is slidably connected in the positioning groove 54.

[0028] Furthermore, bolt grooves 7 are respectively provided on both sides of the two upper semi-circular disks 3 and the two lower semi-circular disks 4 .

[0029] In summary, after the upper half disc 3 and the lower half disc 4 are assembled on the intermediate shaft of the cable winch frame 1, the threaded rod 6 is rotated by a tool, and the threaded rod 6 drives the sliding half 61 to slide in the limiting groove 52 through the threaded groove on the sliding half 61, and the sliding half 61 drives the extrusion rotating rod 63, and the rotating rod 63 squeezes and pushes the connecting block 64, and the rotating rod 63 rotates in the rotating groove 62, and the connecting block 64 pushes the two upper half discs 3 or the lower half disc 4 apart, and the slider 65 slides in the sliding groove 53, and the slider 65 drives The positioning plate 66 slides in the positioning groove 54. When the positioning plate 66 slides to the other side of the positioning groove 54, the positioning plate 66 is blocked by the positioning groove 54 and cannot slide, so that the upper semi-circular disc 3 and the lower semi-circular disc 4 cannot be separated. The distance between the two upper semi-circular discs 3 or the lower semi-circular discs 4 increases, making the overall thickness of the equipment thicker. The thickness of the limiting sheath can be adjusted so that the sheath can better limit the cable drum, preventing the cable drum from sliding on the middle shaft after long-term use of the cable crane, causing deviation and wear of the structure on the cable crane.
