[0001] The utility model relates to the technical field of steel coil uncoiling equipment, in particular to a device for preventing steel coil uncoiling from deviation. Background Art
[0002] Steel coil, also known as coiled steel, is formed into a coil by hot and cold pressing of steel for easy storage and transportation, so as to be used for various subsequent processing operations. The steel coil needs to be unrolled for subsequent processing operations. At present, the unrolling is generally done by placing the steel coil on the expansion and contraction shaft of the unrolling equipment, fixing it, and then rotating the shaft to unroll the steel coil.
[0003] In order to facilitate the insertion and installation of steel coils, the expansion and contraction shaft of current steel coil unwinding equipment is generally supported by a single arm at one end, with the other end open for docking. This also causes the open end to lose support, making it easier for it to tilt downward relative to the other end after long-term use, causing the unwinding to deviate.
[0004] Based on this, the utility model designs a device for preventing the steel coil from unwinding and deviating to solve the above problem. Summary of the Invention

[0024] The steel coil installed in the expansion and contraction reel 2 is supported and fixed so that it is not easy to slide. The open end of the expansion and contraction reel 2 rotates in the sleeve at one end of the sleeve seat 3, and the bottom of the sleeve seat 3 is provided with a counterweight, and the center is at the bottom so that its bottom is always kept in a downward state, so that it can cooperate with the upward-moving support plate 8. After the docking is completed, the telescopic shaft of the hydraulic cylinder 6 is coordinated with the connecting plate 7 to jointly support one end of the expansion and contraction reel 2, making it more stable and not easy to tilt downward, causing the steel coil to deviate and affect the operation. In order to increase the service life of the telescopic shaft, the hydraulic cylinder 6 is protected by a telescopic leather cover 13 of a protective mechanism on the outer wall.
[0025] Preferably, the protective mechanism further includes two collars 12, which are respectively fixed to the bottom of the connecting plate 7 and the top of the body 1, and the two ends of the telescopic leather cover 13 are respectively fixed to the outer walls of the two collars 12;
[0026] The two ends of the telescopic leather cover 13 are respectively fixed to the two collars 12. After installation, the two collars 12 are both sleeved outside the telescopic shaft of the hydraulic cylinder 6 so as not to affect the normal telescopic operation of the telescopic shaft of the hydraulic cylinder 6.
[0027] Preferably, arm plates 14 are fixed to the outer walls of the two collars 12, and the connecting plate 7 and the body 1 are fixed to the arm plates 14 by bolts;
