Referring to fig. 6, in an embodiment, there is provided a shutter regulating method for a shutter regulating apparatus, including:

s1, adjusting the height of the gate 5 by the lifting rod assembly 2;

in the initial state, the hanging beam 1 is located at the end of the rod 25, and as the gate 5 wears and corrodes, the lifter 242 and the driving member 241 drive the hanging beam 1 through the rod 25 to gradually descend along with wearing and maintaining the distance between the gate 5 and the bottom surface of the flow passage 4, and when the rod 25 descends to the limit position, the rod 25 cannot continue descending.

S2, when the lifting rod component 2 descends to the limit position, the adjusting bracket 3 is controlled to extend and support the hanging beam 1;

the handle 34 is rotated to drive the telescopic rod 33 to rotate, so as to drive the push rod 32 to move towards the hanging beam 1, and when the push rod 32 abuts against the hanging beam 1, the adjusting bracket 3 completes temporary support.

S3: detaching the hanging beam 1 from the lifting rod assembly 2, controlling the lifting rod assembly 2 to be lifted and reinstalling the hanging beam 1 on the lifting rod assembly 2;

the position of the support 22 is adjusted downwards, after which the control rod 25 is extended to the extreme position, and the position of the support 22 is adjusted to hold the support 22 against the suspension beam 1, at which point the support 22 can again support the suspension beam 1.

It will be appreciated that the length of the extension of the bar 25 during this step may be any length, but extension to the extreme position reduces the number of adjustments in the relative position of the suspension beam 1.

S4: controlling and adjusting the retraction of the bracket 3;

the adjusting bracket 3 can then be removed, or the adjusting bracket 3 can be left under the suspension beam 1.

When the lifter assembly 2 is lowered to the limit position again, the steps S1 to S4 may be repeated.

It should be noted that, because the hanging beam 1 and the shutter 5 are heavier, when the mandril 32 contacts with the hanging beam 1 and supports the hanging beam 1, the resistance is obviously greatly increased when the handle 34 is continuously rotated, and at this time, the handle 34 can be stopped from rotating, so as to prevent the mandril 32 from continuously extending out and lifting the hanging beam 1 and causing the position change of the hanging beam 1; on the basis, a feeler gauge can be inserted between the mandril 32 and the lifting beam 1 when resistance is sensed, and whether the mandril 32 is solid or not can be determined through the feeler gauge.

It should be noted that when the rod 25 is extended again and the support member 22 is adjusted to abut against the hanging beam 1, whether the support member 22 is solid or not can also be determined by adjusting the resistance and the feeler.
