[0021] The inside fixed setting of bottom frame 1 is provided with first hydraulic cylinder 11, and the movable end of first hydraulic cylinder 11 is fixedly connected with movable side plate 3, and the expansion and contraction of first hydraulic cylinder 11 can drive movable side plate 3 to move left and right on the upper end of bottom frame 1, when movable side plate 3 moves in the direction away from fixed side plate 2, as shown, first shaft sleeve 6, second shaft sleeve 7 and the connecting shaft 10 of one end of rolling mill roll 9 will be separated, at this moment, it is very simple to disassemble rolling mill roll 9, just need to take the other end connecting shaft 10 of a plurality of rolling mill rolls 9 from first shaft sleeve 6, second shaft sleeve 7 in sequence, then through the special forklift, a plurality of connecting shafts 10 are sequentially transported and can complete the disassembly work; Figure 3

[0022] The inside upper end of fixed side plate 2 and movable side plate 3 is fixedly provided with second hydraulic cylinder 12, and the movable end of second hydraulic cylinder 12 is fixedly connected with movable block 5, and second hydraulic cylinder 12 can drive movable block 5 to move up and down, so that the uppermost rolling mill roll 9 can be moved up and down;

[0023] ​The third hydraulic cylinder 14 is fixedly arranged on one side of the movable side plate 3 and the fixed side plate 2 of the bottom frame 1 surface, the movable end of the third hydraulic cylinder 14 is fixedly arranged with the first supporting rod 15, the upper end of the first supporting rod 15 is arranged with the connecting rod 16 on one side, the upper end of the connecting rod 16 is fixedly arranged with the second supporting rod 17, the first supporting rod 15 is located below the first shaft sleeve 6, and the second supporting rod 17 is located at the upper end of the first shaft sleeve 6 and the lower end of the second shaft sleeve 7; although the device can conveniently and quickly release the locking of the rolling mill roller 9 and facilitate disassembly and installation, after the movable side plate 3 is removed, one end of the rolling mill roller 9 lacks support, at this time, the first supporting rod 15 and the second supporting rod 17 lift the lower end of the rolling mill roller 9 by elongating the third hydraulic cylinder 14, so that the stability of the rolling mill roller 9 can be guaranteed; when the rolling mill roller 9 needs to work, the first supporting rod 15 and the second supporting rod 17 are separated from the rolling mill roller 9 by retracting the third hydraulic cylinder 14, so that unnecessary friction loss can be reduced;

[0024] The connecting rod 16 and the first supporting rod 15 are connected through a bearing, so that when the second supporting rod 17 is not needed, the connecting rod 16 can be rotated through the bearing, the second supporting rod 17 and the connecting rod 16 are rotated, the second supporting rod 17 is dislocated from the rolling mill roller 9, and the upper and lower movement of the uppermost rolling mill roller 9 is not affected; when the second supporting rod 17 needs to be used, the second supporting rod 17 is rotated at the lower end of the rolling mill roller 9;

[0025] One end of the first shaft sleeve 6 is fixedly arranged with the connecting gear 13, an external motor and other equipment can be conveniently connected through the connecting gear 13, so that the first shaft sleeve 6 can be driven to rotate, and when the first shaft sleeve 6 rotates, the connecting shaft 10 can be driven to rotate through the spline groove 8, so that the two lower rolling mill rollers 9 can be driven to rotate;

[0026] Working principle: when the device is used, the rolling mill roller 9 is installed in the first shaft sleeve 6 and the second shaft sleeve 7 through the connecting shaft 10; the first shaft sleeve 6 and the second shaft sleeve 7 are connected with the connecting shaft 10 through the spline, so that the first shaft sleeve 6 and the second shaft sleeve 7 can be driven to rotate synchronously with the rolling mill roller 9; in this way, the connecting gear 13 can be driven to rotate by using an external motor and other equipment, so that the first shaft sleeve 6 can be driven to rotate, and the two lower rolling mill rollers 9 can be driven to rotate; at this time, the uppermost rolling mill roller 9 is pushed downward by the extension and retraction of the second electric push rod, so that the three rolling mill rollers 9 cooperate with each other, and the function of rolling steel plates can be achieved;

[0027] When the rolling mill roller 9 needs to be disassembled, the first hydraulic cylinder 11 is retracted, so that the movable side plate 3 is pushed to move away from the fixed side plate 2, Figure 3As shown, at this time, the first shaft sleeve 6, the second shaft sleeve 7 and the connecting shaft 10 at one end of the rolling mill roller 9 are separated, at this time, the rolling mill roller 9 is very simple to disassemble, just a plurality of connecting shafts 10 at the other end of the rolling mill roller 9 are sequentially separated from the first shaft sleeve 6 and the second shaft sleeve 7; then through a special forklift, a plurality of connecting shafts 10 are sequentially transported away to complete the disassembly work; because the space between the bottom frame 1 and the movable side plate 3 is significantly greater than the length of the rolling mill roller 9 plus the connecting shaft 10, so only the connecting shaft 10 of the rolling mill roller 9 is inserted into the shaft sleeve on the surface of the fixed side plate 2, and then the shaft sleeve on the surface of the movable side plate 3 is also sleeved on the outer surface of the connecting shaft 10 through the contraction of the first hydraulic cylinder 11; in this way, the positioning and fixed installation of the rolling mill roller 9 of the device is convenient, and when the rolling mill roller 9 needs to be disassembled subsequently, the one end of the rolling mill roller 9 can be separated from the shaft sleeve, so that the rolling mill roller 9 can be directly inserted and pulled out, thereby facilitating the installation and disassembly of the rolling mill roller 9.

[0028] When the device is used, although the device can conveniently and quickly release the locking of the rolling mill roller 9, facilitate disassembly and installation, after the movable side plate 3 is removed, the one end of the rolling mill roller 9 lacks support, in order to prevent the rolling mill roller 9 from being damaged, at this time, the first supporting rod 15 and the second supporting rod 17 are lifted through the elongation of the third hydraulic cylinder 14, so that the lower end of the rolling mill roller 9 can be guaranteed to be stable; when the rolling mill roller 9 needs to work, the first supporting rod 15 and the second supporting rod 17 are separated from the rolling mill roller 9 through the contraction of the third hydraulic cylinder 14, so that unnecessary friction loss can be reduced.

[0029] When the device is used, the bearing rotating connecting rod 16 can be rotated to make the second supporting rod 17 and the connecting rod 16 rotate, so that the second supporting rod 17 is out of position with the rolling mill roller 9, so that the up and down movement of the uppermost rolling mill roller 9 is not affected; when the second supporting rod 17 needs to be used, the second supporting rod 17 is rotated to the lower end of the rolling mill roller 9.
