[0003] Because the top roller 2 weighs about 100kg, it is completely pulled and carried by the staff, and the labor intensity and danger are relatively large. However, the number of top rollers 2 of the horizontal looper is large, so the replacement amount is also large, and every When replacing the top roller 2 for the first time, the steel belt between the top roller 2 and the bottom roller 3 must be removed. After the replacement of the top roller 2 is completed, the steel belt must be threaded again, which adds a lot of extra work.
Therefore, the replacement of the top roller 2 has been perplexing the construction personnel

The invention provides a replacement system and a replacement method for a top roller of a horizontal type loop. The replacement system comprises a replacement device and a lifting device; the replacement device comprises that a frame is arranged on one of supporting pieces, a rotating shaft is arranged in the frame in a penetrating mode and can rotate relative to the frame and move in the vertical direction relative to the frame; one end of a swinging arm is connected with the rotating shaft; the clamping part is fixedly connected with the top roller, and the clamping part is connected with the other end of the swing arm; a upper jacking mechanism is arranged below the rotating shaft and can drive the rotating shaft to move upwards; the lifting device is used for hoisting the top roller to the ground. According to the replacement system, in the process that the top roller is hoisted to the ground, the top roller is located between the supporting part and the upper-layer walkway, the steel strips arranged between the top roller and the bottom roller do not need to be disassembled, so that the construction efficiency and the safety of replacing the top roller are greatly improved.
Description
technical field [0001] The invention relates to the technical field of top roller replacement devices, in particular to a replacement system and method for a top roller of a horizontal looper. Background technique [0002] Major domestic steel mills have electro-galvanizing, pickling rolling, hot-dip plating and other units. Horizontal loopers are widely used in these units. Their main function is to store strip steel, and perform coil change, strip welding, and roll change in the unit. To ensure the normal operation of the unit. The horizontal looper in some hot-dip galvanizing units is in a closed structure due to the characteristics of process layout. Since the looper area is often tens of meters long, there is no special lifting tool in the entire area. like figure 1 As shown, a top roller 2 is installed on the top frame body 1, and a bottom roller 3 is installed on the bottom support close to the ground, and a steel belt (not shown) is arranged between the top roller ...
