The retraction and release of the plastic covering require the use of anchor chains and pulleys.
[0003] At present, the anchor chains used for the retraction and release of plastic coverings in salt fields are prone to rotation during use, which affects the traction of the plastic coverings, and it is easy to have problems such as incomplete release or folding of the plastic coverings. Moreover, the rotating anchor chains are also easily damaged, reducing their service life. For this reason, we propose an anti-anchor chain rotation device. Content of the Utility Model
[0004] The purpose of the utility model is to provide an anti-anchor chain rotation device, which has the advantages of being able to guide and correct the anchor chain during traction, preventing the anchor chain from rotating, which is beneficial to the retraction and release of the plastic covering in the salt field, avoiding incomplete release and folding of the plastic covering, and at the same time extending the service life of the anchor chain. It solves the problem that the anchor chains used for the retraction and release of plastic coverings in salt fields are prone to rotation during use, which affects the traction of the plastic coverings, and it is easy to have problems such as incomplete release or folding of the plastic coverings. Moreover, the rotating anchor chains are also easily damaged, reducing their service life.
[0005] To achieve the above object, the utility model provides the following technical solution: an anti-anchor chain rotation device, including an anchor chain pulley and a pulley frame. The anchor chain pulley is rotatably installed inside the pulley frame through a wheel shaft. An annular groove is provided on the outer surface of the anchor chain pulley. Inside the pulley frame, connecting frames are symmetrically rotatably installed near the front surface and the rear surface above the anchor chain pulley through rotation axes. The ends of both connecting frames are fixedly connected with anchor chain guiding blocks, and cross-through openings are provided on the outer surfaces of both anchor chain guiding blocks.
[0006] Preferably, a fillet is provided on the outer surface of the anchor chain guiding block near the edge of the cross-through opening.
[0007] Preferably, a C-shaped ring is rotatably installed on the upper surface of the pulley frame through a connecting shaft.
[0008] Preferably, one end of the C-shaped ring is slidably sleeved with a sleeve, and the sleeve and the end of the C-shaped ring are fixedly connected by threads.
[0009] Preferably, friction protrusions are provided on the outer surface of the sleeve.
[0010] Preferably, a limiting block is provided at one end of the C-shaped ring, and a limiting ring is provided at one end of the sleeve near the limiting block.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] 1. By providing a pulley frame, an anchor chain pulley, an annular groove, a rotating shaft, a connecting frame, an anchor chain guiding block and a cross-through opening, the present utility model can guide and correct the anchor chain during traction, prevent the anchor chain from rotating, which is beneficial to the traction and retraction of the plastic covering in the salt field, avoid the phenomena of incomplete release and folding of the plastic covering, and at the same time extend the service life of the anchor chain. Before the anchor chain for the plastic covering retraction in the salt field enters the inside of the pulley frame and contacts the anchor chain pulley, and when it exits from the inside of the pulley frame, it first passes through the cross-through opening on the anchor chain guiding block. Since the anchor chain is composed of multiple anchor chain links connected end to end, when the first anchor chain link passes horizontally through the cross-through opening, the second anchor chain link passes vertically through the cross-through opening, and so on. In this way, the cross-through opening guides and corrects the anchor chain during traction and restricts the rotation of the anchor chain.
[0013] 2. By providing rounded corners, the present utility model is beneficial for the anchor chain to enter the cross-through opening and prevent the sharp parts at the edge of the cross-through opening from causing significant wear to the anchor chain.
[0014] 3. By providing a C-shaped ring and a sleeve, the present utility model achieves the effect of facilitating the disassembly and assembly of the pulley frame. The rope for fixing the pulley frame enters the inside of the C-shaped ring from the notch of the C-shaped ring, and the pulley frame can be fixed by the C-shaped ring. At the same time, slide the sleeve to cover the notch of the C-shaped ring to prevent the rope from slipping out of the notch.
[0015] 4. By providing a limiting block and a limiting ring, the present utility model achieves the effect of improving the overall stress strength of the C-shaped ring. The end of the C-shaped ring and the sleeve are fixed by threaded connection, and the other end of the C-shaped ring and the sleeve are stressed by the limiting block and the limiting ring, which makes up for the reduction in the overall stress strength of the C-shaped ring due to the notch.

The anchor chain pulley 6 is rotatably installed inside the pulley frame 8 through a wheel shaft 7. An annular groove 11 is provided on the outer surface of the anchor chain pulley 6. The annular groove 11 plays a role in limiting the anchor chain for the plastic covering collection and release in the salt field. Inside the pulley frame 8, connecting frames 2 are symmetrically and rotatably installed through rotating shafts 3 at positions close to the front surface and the rear surface above the anchor chain pulley 6. The ends of the two connecting frames 2 are fixedly connected with anchor chain guiding blocks 1. Cross-through openings 10 are provided on the outer surfaces of the two anchor chain guiding blocks 1. Rounded corners 9 are provided at positions close to the edges of the cross-through openings 10 on the outer surfaces of the anchor chain guiding blocks 1. The provision of the rounded corners 9 is beneficial for the anchor chain to enter the cross-through openings 10 and prevents large wear of the anchor chain caused by the sharp parts at the edges of the cross-through openings 10.

Since the anchor chain is composed of multiple anchor chain rings connected end to end, when the first anchor chain ring horizontally passes through the cross-through opening 10, the second anchor chain ring vertically passes through the cross-through opening 10, and so on. In this way, the cross-through openings 10 play a guiding and correcting role for the anchor chain being towed, restricting the rotation of the anchor chain, which is beneficial for the traction collection and release of the plastic covering in the salt field, avoiding the phenomena of incomplete release and folding of the plastic covering, and at the same time prolonging the service life of the anchor chain.

One end of the C-shaped ring 5 is provided with a limiting block 14, and a limiting ring 15 is provided at one end of the sleeve 12 close to the limiting block 14.
[0027] In this embodiment, the rope for fixing the pulley frame 8 enters the inside of the C-shaped ring 5 from the notch of the C-shaped ring 5, and the pulley frame 8 can be fixed by the C-shaped ring 5. At the same time, the sleeve 12 is slid to cover the notch of the C-shaped ring 5 to prevent the rope from slipping out of the notch. The end of the C-shaped ring 5 and the sleeve 12 are fixedly connected by threads, and the other end of the C-shaped ring 5 and the sleeve 12 are stressed by the limiting block 14 and the limiting ring 15, which makes up for the overall stress intensity reduction of the C-shaped ring 5 due to the notch.
