In a rolling material production workshop, the strong torque of a speed reducer is transmitted to a roller through a universal shaft to roll billets. And rolling the steel billet into a material step by step through a plurality of groups of flat and vertical rolling rollers of the rolling line. When the abrasion of the roller channel is out of limit, the roller change operation is needed to be organized. When the roll replacement operation of the vertical rolling mill is performed, after the rolls are installed in place, the rolls and the universal shafts need to be connected to each other, which is hereinafter referred to as a sleeve operation.
The rolling mill mainly comprises a main motor, a reduction gearbox, two universal shafts and two rollers. One side of the universal shaft is connected with the output end of the reduction gearbox, and the other side is connected with the roller. The distance between the two output ends of the reduction box is smaller than the distance between the roller heads of the roller, so that the distance between the universal shafts is manually interfered in the roller sleeving operation process to complete the roller sleeving operation by matching with the distance between the roller heads of the roller.
The vertical roller sleeve operation requires four persons to cooperate to complete roller operation due to equipment environment factors, in the roller sleeve operation process, two operators need to stand on a rolling channel between two groups of rolling mills, the crowbars are used for cooperation, the distance between universal shafts is adjusted to be close to the distance between roller heads, and a commander informs a near-control console operator to click a lifting roller bracket, so that the roller heads and the universal shafts are connected with each other.
However, the above operation mode has the following defects that an operator needs to stand at a high place in a complex field environment, and uses a crowbar to adjust the distance between the universal shafts, so that the operator has high labor intensity and is easy to break in the adjustment process. In the operation process of adjusting the distance between the universal shafts, the distance between the universal shafts is difficult to guarantee, whether the distance between the universal shafts is proper or not needs to be confirmed through multiple test sleeves, and the operation efficiency is low. In order to design an auxiliary tool, the sleeve roller operation is safer and more efficient.
Based on the supporting device, the invention provides a supporting device, which is applied to the technical field of steel rolling equipment, is particularly suitable for auxiliary positioning sleeve roller operation of a vertical rolling mill, can improve the field operation safety, improve the sleeve roller operation efficiency, and reduce the labor intensity of operators, so that the sleeve roller operation is safer and more efficient.
