Detailed Implementation

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 and Figure 2 As shown, an auxiliary support mechanism for a steel coil unwinding machine is disclosed. The unwinding machine includes a base 1 and an unwinding machine body 2. An unwinding shaft 21 is provided on the unwinding machine body 2. One end of the unwinding shaft 21 is rotatably connected to the unwinding machine body 2, and the auxiliary support mechanism is located below the other end of the unwinding shaft 21. The auxiliary support mechanism includes a support frame 31 and a hydraulic cylinder 32. The support frame 31 is hinged to the base 1, and a first locking bolt 33 is threaded onto the base 1 to fix the support frame 31 to the base 1. The hydraulic cylinder 32 is vertically mounted on the top of the support frame 31, and a mounting bracket 34 is fixed on the push rod of the hydraulic cylinder 32. Two support wheels 35 are rotatably connected inside the mounting bracket 34, and when the push rod of the hydraulic cylinder 32 extends outward, the two support wheels 35 can jointly support the outer circumferential surface of the unwinding shaft 21. A first handle 36 is fixed on both sides of the support frame 31.

[0014] Working principle: When feeding the steel coil onto this uncoiling machine, first remove the first locking bolt 33 and bend the support frame 31 outward to a horizontal position. Then, use the overhead crane to feed the steel coil onto the uncoiling shaft 21. Next, rotate the support frame 31 upward to a vertical position and lock the first locking bolt 33. Finally, control the extension of the push rod of the hydraulic cylinder 32 to lift the two support wheels 35 to abut against the outer circumference of the uncoiling shaft 21 at the suspended end. This auxiliary support mechanism can be closed onto the uncoiling shaft 21 or opened. When closed, it can effectively support the suspended end of the uncoiling shaft 21, thus preventing it from bending and being damaged. When opened, it allows us to feed the steel coil onto the uncoiling machine, making it very flexible and convenient to use.

[0015] like Figure 1 and Figure 2As shown, the top of the support frame 31 is hinged with a mounting plate 37, the hydraulic cylinder 32 is fixed on the mounting plate 37; the top end of the mounting frame 34 is threadedly connected with a second locking bolt 38, and the second locking bolt 38 can fix the mounting plate 37 on the support frame 31; a pair of second handles 39 are fixed on the outer wall of the hydraulic cylinder 32. According to production requirements, sometimes we need to unload the steel coil which has been partially unwound, at this time, if the outer diameter of the steel coil is small, we can remove the second locking bolt 38, and only open the mounting plate 37 to realize unloading, thereby reducing the labor intensity of the workers.

[0016] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
