As shown in fig. 1 to 8, an embodiment of the present invention provides a roller device capable of quickly changing rollers, including a frame 1 and an upper roller box 2, where an upper roller changing track 11 is arranged on the frame 1, the upper roller box 2 is provided with a plurality of holes, each hole is provided with a T-shaped bolt 3, each hole is provided with a first structural hole 24 and a second structural hole 25, the first structural hole 24 is a rectangular countersunk hole formed at the bottom of the corresponding hole and has a downward opening direction, the second structural hole 25 is a rectangular through hole penetrating the corresponding hole from top to bottom, the first structural hole 24 is in cross communication with the second structural hole 25, a head 31 of the T-shaped bolt 3 is embedded in the first structural hole 24, and a screw passes through the second structural hole 25 and the top of the frame 1 and is locked by a lock nut 4.
The structure of the frame 1 and the upper roll box 2 is conventional in the art and will not be described herein. The top of the frame 1 may be provided with a fixing plate 12 for fitting with the locking nut 4 after the T-bolt 3 is inserted.
In one embodiment, as shown in fig. 1 to 8, the holes are distributed on two sets of bearing blocks 21 of the upper roller box 2. Further preferably, each set of bearing blocks 21 is provided with a plurality of holes and is arranged on both sides of a vertical symmetry plane of the roller, wherein the vertical symmetry plane of the roller is parallel to the axis of the roller; the hole sites on the bearing seat 21 are distributed on two sides of the vertical symmetrical plane of the roller, so that the stability and reliability of the mounting structure of the upper roller box 2 can be ensured, and the working performance of the upper roller 23 can be ensured. Alternatively, as shown in fig. 2, 4, 6 and 8, each set of bearing blocks 21 is provided with two holes, which are symmetrically distributed with respect to the vertical symmetry plane of the roller.
When the holes are distributed on the bearing seat 21, correspondingly, a first structure hole 24 is formed at the bottom of the bearing seat 21, and a second structure hole 25 is penetrated from the bottom of the bearing seat 21 to the top of the bearing seat 21.
Wherein, preferably, the width of the second structure hole 25 is larger than the width of the head of the T-shaped bolt 3, so as to facilitate the T-shaped bolt 3 to pass through the second structure hole 25.

Further, the roll changing cushion block 61 is mounted on the frame 1 through the chain 62 and has a working position padded between the lock nut 4 and the frame 1 and an idle position far away from the lock nut 4, so that the use of the roll changing cushion block 61 is facilitated, and the influence on the roll changing operation caused by the loss of the roll changing cushion block 61 is avoided. The lock nut 4 is generally provided with a lock washer 5, and the roll changing spacer 61 can cushion the lock washer 5 together with the lock nut 4.
According to the roller equipment provided by the embodiment, the hole groups of the first structural hole 24 and the second structural hole 25 are matched with the T-shaped bolt 3, the head 31 of the T-shaped bolt 3 is embedded in the first structural hole 24 during normal production, the constraint reliability of the T-shaped bolt 3 on the upper roller box 2 is improved, the upper roller box 2 is in a hanging form, the head 31 of the T-shaped bolt 3 can improve the hanging reliability of the upper roller box 2, the acting force born by the upper roller box 2 can be better transmitted to the rack 1, and the working reliability of the upper roller is effectively improved; when the roll is changed, the T-shaped bolt 3 is only required to be lifted to the upper part of the upper roll box 2 through the second structure hole 25, the roll changing operation can be completed without taking the T-shaped bolt 3 down from the rack 1, the roll changing efficiency can be obviously improved, the roll changing workload can be reduced, and meanwhile, the risk of bolt loss can be avoided.
Optionally, the roll equipment is steel rolling equipment which comprises a roll box and needs to be replaced frequently, such as a rolling mill, a stretch bending straightener or a straightener, and can be widely applied to continuous strip processing lines of silicon steel, carbon steel, stainless steel, nonferrous materials and the like; further, a roll device such as a wringing roll or a steering roll may be used.
As shown in fig. 1 to fig. 8, an embodiment of the present invention further provides a roll changing method of the roll apparatus, including:
when the old roller is removed, the locking nut 4 is unscrewed, so that the travelling mechanism 22 of the upper roller box 2 to be replaced is lowered onto the upper roller replacing track 11; then the head 31 of each T-shaped bolt 3 is separated from the first structural hole 24, and after rotating for 90 degrees, the head rises to the upper part of the upper roll box 2 to be replaced through the second structural hole 25; then taking the upper roller box 2 to be replaced out of the frame 1;
