Problems solved by technology
Since the distance between the swing door and the steel beam on which the gourd is hung on the upper part is very small, it is impossible to hang the gourd in a standard manner. In addition, the stability of the gourd is poor after being hoisted, and the swing door is easy to shake and it is difficult to achieve accurate positioning. Therefore, the disassembly and assembly time is long and the labor intensity is high. Large, low construction efficiency

The invention provides a special device for replacing a horizontal loop swing door. The special device comprises a base. First idler wheels and two first guide rails are arranged on the base. The first guide rails are located on the base. Supporting trolleys are arranged between the two first guide rails and can do reciprocating movement in the length direction of the first guide rails. Adjustable supporting parts for supporting the horizontal loop swing door are arranged on the supporting trolleys. The invention further provides a method for replacing the horizontal loop swing door through the special device. The special device is simple and reliable in structural style. A swing door device is supported by adjusting the adjustable supporting parts. Compared with the lifting stability and positioning accuracy of an original hoist, the stability and positioning accuracy of the special device are remarkably improved. The labor efficiency of adjustment of the horizontal loop swing door is improved. Personnel investment and consumption are reduced. The quality and safety of project implementation are guaranteed.
Description
Technical field [0001] The invention relates to a method for replacing mechanical equipment, in particular to a special device and method for replacing a horizontal looper swing door. Background technique [0002] All major domestic steel plants have electro-galvanizing, pickling rolling, continuous rolling 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 operations in the unit. It can ensure the normal operation of the unit. Because the horizontal looper is arranged horizontally and generally has a length of tens of meters, the strip steel is tightened and distributed in the length direction by the rollers at both ends. Therefore, an idler device must be installed in the length direction to avoid the natural sag of the strip and affect production. The expansion and contraction of the looper is realized by the looper trolley running at different positions in th...
