In this embodiment, referring to fig. 1, two ends of the first screw 400 are respectively provided with a first thread and a second thread with opposite thread directions, a first threaded hole adapted to the first thread is provided in one end of the first threaded cylinder 410, a second threaded hole adapted to the second thread is provided in one end of the second threaded cylinder 420, when it is required to adjust the distance between the support plate 500 and the suspension bar 100, it can be rotated by the first screw 400, and further, the first and second screw holes are screwed so that the first and second screw cylinders 410 and 420 are relatively far apart, thereby adjusting the distance between the support plate 500 and the hanger bar 100, and when the distance between the two is increased, in the ascending process of the suspender 100, the larger the outward expansion amplitude of the extrusion supporting plate 500 is, so as to adapt to the coiled materials with different specifications, and the supporting plate 500 can be attached to the inner wall of the central hole of the coiled material to stably support the coiled material.

In this embodiment, referring to fig. 2 and 3, a through hole 501 is formed in the support plate 500 at the lower end of the second mounting lug 530, a contact plate 510 is movably disposed in the through hole 501, the contact plate 510 can move horizontally in the through hole 501, one end of the contact plate 510 extends toward the second threaded cylinder 420, the other end of the contact plate 510 extends to the other side of the support plate 500 through the through hole 501, a plurality of pin holes 511 are sequentially disposed in the horizontal direction of the contact plate 510, when the contact plate 510 and the support plate 500 need to be relatively fixed, only the pin 512 penetrates through the pin hole 511, so that the pin 512 contacts the side surface of the support plate 500 to limit the contact plate 510 from being separated from the support plate 500, so as to realize the relative fixing between the contact plate 510 and the support plate 500, and then the relative length between the support plate 510 and the second threaded cylinder 420 can be adjusted, so that when the entire hanger is in a natural state (a state before the disc material is not hoisted in a natural state), because one end of the abutting plate 510 abuts against the second threaded cylinder 420, the rotation angle of the supporting plate 500 around the end of the second threaded cylinder 420 through the second mounting lug 530 is also limited, and when the length of the extending plate on one side of the supporting plate 500 is longer, the angle of the included angle formed between the supporting plate 500 and the guide rod 300 behind the abutted second threaded cylinder 420 is smaller, and thus, the supporting plate 500 is closer to the guide rod 300, so that when the whole hanger extends into the central hole of the coiled material, the problem that the hanger enters the coiled material due to the outward expansion of the supporting plate 500 is influenced due to the excessive angle between the supporting plate 500 and the guide rod 300 is avoided, and when the supporting plate 500 is inserted into the central hole of the coiled material, the outward expanded supporting plate 500 collides with the coiled material, and further the copper pipe is damaged is avoided.

The coil is generally twined into the disc by the copper pipe, and its inside center has seted up the centre bore, and during hoist and mount, the hoist inserts in the centre bore to backup pad 500 through the hoist and well pore inner wall laminating back are fixed the coil.

Specifically, how to hoist the coil stock in the embodiment is described in detail;

referring to fig. 1 and 2, in this embodiment, for convenience of description, a through hinge point of the first threaded cylinder 410 and the first mounting lug 110 through the pin 512 is referred to as a hinge point b, a hinge point between the second threaded cylinder 420 and the second mounting lug 530 is referred to as a point a, a hinge point of the guide rod 300 and the second threaded cylinder 420 is referred to as a point C, when the coiled material is hoisted, the suspension rod 100 is driven by the lifting device to drive the support plate 500 to be inserted into the central hole of the coiled material, then when the suspension rod 100 is raised, the telescopic rod presses the guide rod 300 to expand outwards around the third mounting lug and drive the support plate 500 to support and cling to the inner wall of the coiled material, at the same time, the first threaded cylinder 410 of the telescopic rod is raised and synchronously drives the second threaded cylinder 420 to rotate around the point C, when the first threaded cylinder 410 is raised, the second threaded cylinder 420 is also raised, and when the second threaded cylinder 420 is raised, the limit of the abutting plate 510 is lost, this is that backup pad 500 uses a point to expand outwards as the rotation point in its backup pad 500's upper end under the action of gravity, and then increases the number of degrees of activity contained angle between backup pad 500 and the guide bar 300, realizes backup pad 500 laminating coil's centre bore inner wall, and when the spacing ring 120 of jib 100 was rising and butt the movable bar bottom, a plurality of backup pads 500 were opened completely to the inner wall of laminating coil, the realization was got the fixed clamp of charging tray.

In this embodiment, referring to fig. 2, in order to make the hanger suitable for the coil materials with different specifications and heights, a movable sleeve 310 is sleeved on the guide rod 300 in an axial sliding manner, one side of the movable sleeve 310 is connected with a pressing plate 340 through a bracket 330, the movable sleeve 310 is connected with the guide rod 300 through a second screw 320, so that after the movable sleeve 310 slides and is adjusted on the guide rod 300, the distance between the pressing plate 340 and the supporting plate 500 is changed, when the hanger is completely inserted into the central hole of the material throwing, the bottom of the pressing plate 340 abuts against the upper end of the coil material, and after the supporting plate 500 stably supports the coil material, the bottom of the pressing plate 340 also abuts against the coil material, thereby improving the axial limit of the hanger on the coil material, facilitating adjustment of the insertion depth of the supporting plate 500 into the central hole of the coil material, and avoiding the situation that when the supporting plate 500 enters into the central hole of the coil material along with the hanger rod 100, the support plate 500 is separated from the central hole of the coiled material due to the over-deep insertion, so that the support plate 500 can stably abut against the inner wall of the central hole of the coiled material after the support plate 500 is inserted into the central hole of the coiled material along with the suspension rod 100.

In this embodiment, in order to deal with the diameters of the central holes of the coiled materials with different specifications and sizes, it is ensured that the support plate 500 can be attached to the inner wall of the central hole of the coiled material when the suspension rod 100 ascends to drive the support plate 500 to expand outward, and the initial length between the support plate 500 and the suspension rod 100 can be changed by rotating the first screw 400 in the first threaded cylinder 410 and the second threaded cylinder 420.

While the present invention has been described with reference to the particular illustrative embodiments, it will be understood by those skilled in the art that the present invention is not limited thereto, and may be embodied in many different forms without departing from the spirit and scope of the present invention as set forth in the following claims.
