[0021] Specifically, the first moving mechanism 3 includes a sliding key 301 and a limiting sliding groove 302. The sliding key 301 is fixedly installed on the core shaft 2. The limiting sliding groove 302 is opened on the inner wall of the fan-shaped plate 7 corresponding to the sliding key 301. The sliding key 301 is movably buckled and installed in the limiting sliding groove 302.

[0022] In this embodiment, the slide key 301 is fixedly connected to the core shaft 2 by bolts, and the slide key 301 moves left and right with the core shaft 2, so that the slide key 301 moves left and right in the limiting slide groove 302. Since the limiting slide groove 302 is an inclined structure, when the slide key 301 moves in the limiting slide groove 302, the slide key 301 drives the fan-shaped plate 7 to expand and contract, and the cross-sections of the slide key 301 and the limiting slide groove 302 are both T-shaped structures.

[0023] Specifically, the second moving mechanism 5 has the same structure as the first moving mechanism 3 .

[0024] In this embodiment, the second moving mechanism 5 drives the sector plate 7 to expand and contract synchronously.

[0025] Specifically, the side walls of the pyramid 6 are provided with mold holes 13 at positions corresponding to the sliding keys 301 for the sliding keys 301 to pass through.

[0026] In this embodiment, the mold hole 13 meets the requirement that the sliding key 301 moves up and down in the pyramid 6.

[0027] Specifically, the limiting mechanism 8 includes a retaining ring 801 and a locking ring 802 , and the retaining ring 801 and the locking ring 802 are sequentially installed on the main shaft 1 corresponding to the left and right sides of the sector plate 7 from near to far.

[0028] In this embodiment, the retaining ring 801 and the locking ring 802 cooperate to limit the position of the sector plate 7 and the pyramid 6 .

[0029] Specifically, the inner diameter of the main shaft 1 matches the core shaft 2 , and a gear 14 is fixedly mounted on the right side of the main shaft 1 .

[0030] In this embodiment, the gear 14 can be connected to an external transmission, so that the main shaft 1 drives the sector plate 7 to rotate.

[0031] Specifically, the driving mechanism 12 includes a cylinder 121, a nut 122, a piston 123 and a rotary joint 124. The cylinder 121 is installed on the left side of the mounting seat 11, and the cylinder 121 is sleeved on the left end of the core shaft 2. The piston 123 is installed on the left end of the core shaft 2 in the cylinder 121 through the nut 122, and the rotary joint 124 is installed on the left side wall of the cylinder 121.

[0032] In this embodiment, the rotary joint 124 is connected to the external hydraulic cylinder pipeline, and the external hydraulic pressure flows into the cylinder 121. The hydraulic oil pushes the piston 123 to move to the right, so that the piston 123 drives the core shaft 2 to move to the right.

[0033] When in use, the initial state of the driving mechanism 12 is that there is no hydraulic oil, and the core shaft 2 is at the leftmost position. At this time, the sliding key 301 in the first moving mechanism 3 and the second moving mechanism 5 is located at the leftmost position in the limiting slide groove 302. At the same time, the sliding key 301 drives the pyramid 6 to the leftmost position. The sliding key 301 and the pyramid 6 expand the four sector plates 7 to make the reel formed by the four sector plates 7 have the largest diameter. The gear 14 is connected to the external transmission component, so that the gear 14 drives the main shaft 1 to rotate, and the main shaft 1 drives the reel of the four sector plates 7 to rotate for winding. When the winding is completed, the driving mechanism The rotary joint 124 in the structure 12 is connected to the external hydraulic cylinder pipeline, and the external hydraulic fluid flows into the cylinder 121. The hydraulic oil pushes the piston 123 to move to the right, so that the piston 123 drives the core shaft 2 to move to the right, and the core shaft 2 drives the sliding key 301 and the pyramid 6 to move to the right. The sliding key 301 moves to the right in the limiting slide groove 302, so that the four sector plates 7 shrink. At this time, the diameter of the reel formed by the four sector plates 7 becomes smaller, and the diameter of the hydraulic reel can be adjusted. The smaller the diameter of the hydraulic reel, the easier it is to load and unload the hydraulic reel quickly, which greatly improves work efficiency and production benefits.

[0034] To sum up, in the solid hydraulic reel structure, the driving mechanism 12 drives the core shaft 2 to move left and right, so that the core shaft 2 drives the first moving mechanism 3 and the second moving mechanism 5 to move telescopically, so that the reel formed by the four fan-shaped plates 7 can expand and contract, and the diameter of the hydraulic reel can be adjusted, which is convenient for rapid loading and unloading, greatly improving work efficiency and improving production benefits.
