升降台广泛用于大、中型型钢、轨梁、钢坯、劳特式钢板轧机等。升降台摆动机构多采用曲柄摇杆机构(图1),其工作特点是快速升降,频繁开启制动。为实现快速开启制动,减小驱动电机容量,摆动机构设有平衡重以平衡台面重量,并按物理摆原理设计平衡杆。大型升降台台面重达百吨以上,平衡重
Lifts are widely used in large and medium-sized steel, rail beams, billet, rolling mill and other steel plate. Lifting platform swing mechanism to use more crank rocker mechanism (Figure 1), its work is characterized by rapid movements, frequently open the brake. In order to achieve rapid opening of the brake and reducing the capacity of the driving motor, the swinging mechanism is provided with a balance weight to balance the weight of the tabletop and design the balance bar according to the principle of physical swinging. Large lifting platform mesa weighing more than 100 tons, balance weight
