The working principle of the embodiment is as follows: the base plate 1 is arranged on a semitrailer, a steel coil 52 is hung between two bases 2 through a hanging device, the steel coil 52 descends to be in contact with a limit roller 12 and a supporting piece 7, when the steel coil 52 is in contact with the limit roller 12, the limit roller 12 can be stressed to rotate and can be pressed into the bases 2 to avoid clamping the steel coil 52, the steel coil 52 specifically presses down the limit roller 12, the limit roller 12 moves from a first opening 13 to the bases 2 while rotating, under the limit guiding effect of a guide rail 10, a sliding block 11 and a U-shaped connecting frame 15 linearly move along the track of the guide rail 10, a push rod 41 moves at a first long and narrow opening 42 and a second long and narrow opening 44, a second pressure spring 14 compresses, the U-shaped connecting frame 15 drives a steel wire 21 to move, under the elastic force of a volute spring 19, a limit shaft 17 winds the steel wire 21 to enable the steel wire 21 to be in a tensioning state, or the U-shaped connecting frame 15 drives the steel wire 21 and the limit shaft 17 to move, the limit shaft 17 unwinds the steel wire 21, and the steel wire 21 is always in a tensioning state;
after the steel coil 52 presses down the supporting piece 7, the first pressure spring 8 compresses, the supporting piece 7 is grounded and bears load, the top end of the supporting piece 7 which is not contacted with the steel coil 52 is higher than the bottom end of the steel coil 52 under the support of the first pressure spring 8, the steel coil 52 can be limited to axially transversely move, at the moment, the supporting piece 7 contacted with the steel coil 52 bears load, each limiting roller 12 is attached to the steel coil 52, and the steel coil 52 is kept stable;
then, the locking mechanism is operated to eject the limiting plate 32 out of the limiting roller 12, the limiting roller 12 is locked, specifically, the rotary handle 25 is screwed, under the guiding action of the guide rod 23, the screw 24 drives the threaded sleeve 26 and the locking frame 22 to move and approach the base 2, the push plate 43 contacts with the limiting rings 45 on the inner side of the threaded sleeve 26 and the locking frame 22, the push rod 41 and the conical head 39 are pushed to move, the conical head 39 contacts with the inclined surfaces 40 of the shrink sleeves 31 at the same time, the conical head 39 pushes the shrink sleeves 31 to move radially outwards along the limiting roller 12 under the limiting action of the limiting sleeve 30, the tension spring 37 stretches, the limiting plate 32 stretches out of the limiting roller 12 from the third opening 33, part of the limiting plate 32 cannot continuously stretch out after contacting with the steel coil 52 or the base 2, the third compression spring 34 compresses, the shrink sleeves 31 can continuously move until the first limiting disc 20 is tightly engaged with the second limiting disc 27, the limiting shaft 17 is limited to rotate, and the U-shaped connecting frame 15 is further limited to move towards one side of the guide rail 10 far away from the first opening 13. Therefore, the steel coil 52 can not press the limit roller 12 into the base 2 any more, so that the position of the steel coil 52 is limited, the limit plate 32 is approximately blocked at the first opening 13, the rotation of the limit roller 12 is limited, meanwhile, the limit plate 32 is contacted with the steel coil 52, the limit plate 32 serves as an increased limit, the rotation of the steel coil 52 is limited, and the fixing stability of the steel coil 52 is improved; finally, the fixing belt passes through the binding hooks 51 to fix the steel coil 52.
For steel coils 52 with different sizes, the distance between the two bases 2 can be adjusted, if the steel coils 52 with larger sizes need to be fixed, the distance between the two bases 2 needs to be increased, so that each limit roller 12 can contact the steel coils 52, after the convex strips 48 are clamped into the grooves 47, the bolts 28 pass through the first mounting holes 49 and the second mounting holes 50, and the positioning plate 46 is fixed on the bottom plate 1.
When the steel coil 52 is required to be dismounted, the rotary handle 25 is reversely screwed, the locking frame 22 is far away from the base 2, the first limiting disc 20 is separated from the second limiting disc 27, the push plate 43 is contacted with the limiting ring 45 on the outer side of the push plate, the push rod 41 and the conical head 39 are pulled to move, the conical head 39 does not jack the shrinkage sleeves 31 any more, under the pull force of the tension spring 37, each shrinkage sleeve 31 is reset, and the limiting plate 32 is shrunk in the limiting roller 12.
