Embodiment Construction
[0022] The present invention will be further described below in conjunction with the accompanying drawings.
[0023] The online roll changing device provided by the present invention includes a frame 6 supporting the upper and lower squeezing roller pairs 4 and 3, and an upper track 2 is arranged on the frame 6 above the bearing housing 9 of the upper squeezing roller 4. The frame 6 below the dry roll 3 bearing block 10 is provided with a lower track 8, and the bearing blocks 9 at both ends of the upper squeeze dry roll 4 are placed on the upper track 2 by a suspension block 5, and the bearing blocks 10 at the two ends of the squeeze dry roll 3 are all placed on the upper track 2. Place on the lower track 8 by the tackle 7, such as figure 1 , wherein, the upper track 2 is provided with two parallel ones, and the lower track 8 is provided with two parallel ones, such as figure 2 Described hanging block 5 comprises the roller 51 that is placed on the upper track 2, the horizon...

A provided online roller changing device comprises a frame used for supporting an upper and lower squeezing roller pair, and is characterized in that: an upper track is disposed on the frame above the bearing pedestals of an upper squeezing roller; a lower track is disposed on the frame below the bearing pedestals of a lower squeezing roller; the bearing pedestals disposed at the two ends of the upper squeezing roller are both disposed on the upper track via suspension pulleys; and the bearing pedestals disposed at the two ends of the lower squeezing roller are both disposed on the lower track via pulleys. The squeezing roller pair can be conveniently changed in good time according to practical production requirement just by moving the suspension pulleys and the pulleys so as to simultaneously moving in or moving out the upper and the lower squeezing rollers, and production does not need stopping; and therefore the online roller changing device is convenient and fast for roller changing, is time-saving, labor-saving, high in stability and reliability, none in damage to products, equipment and operators, safe, practical, saved in manpower resource, and helps to substantially improve production efficiency, reduce production cost and completely realize online roller changing.
Description
technical field [0001] The invention relates to a roll changing device, in particular to an online roll changing device, which belongs to the technical field of design and manufacture of metal processing equipment. Background technique [0002] In the continuous galvanizing production process of steel strip, passivation of steel strip is an important process after galvanizing of steel strip. After passivation, two sets of wringing rollers are needed for wringing. Since the galvanizing production line requires continuous production, and the passivated squeeze roller is an easy-to-wear part, when the strip substrate is good and normal, the squeeze roller needs to be replaced after producing 3,000 tons of strip steel. If the raw material strip When there are breaks or waves, the replacement frequency of the squeeze roller will be higher, and each time the squeeze roller is replaced, the squeeze roller must be hoisted from the passivation box by a driving car to replace it, so t...
