The invention discloses a high-boron austenitic heat-resistant steel hoisting clamp and a hoisting method thereof, and relates to the technical field of steel hoisting, the high-boron austenitic heat-resistant steel hoisting clamp comprises a bottom plate, a plurality of pairs of U-shaped plates are arranged on the front side and the rear side of the bottom surface of the bottom plate, an L-shaped plate is arranged below each U-shaped plate, a U-shaped seat is arranged on the top surface of each L-shaped plate, and a pair of hinge rods is arranged between each U-shaped plate and the corresponding U-shaped seat; notched gears are fixedly arranged at the top ends of the hinge rods located on the inner side, a plurality of rectangular through holes are formed in the top face of the bottom plate, a double-face rack is inserted into each rectangular through hole, and each double-face rack is connected with the corresponding pair of notched gears in a meshed mode. A rectangular notch is formed in the bottom of each L-shaped plate, a folded plate is arranged in each rectangular notch, and the middle of each folded plate is movably hinged to the corresponding rectangular notch through a pin shaft. The high-boron austenitic heat-resistant steel hoisting tool not only improves the clamping stability during hoisting of high-boron austenitic heat-resistant steel, but also effectively prevents the high-boron austenitic heat-resistant steel from falling off during hoisting.
本发明公开了高硼奥氏体耐热钢吊运夹具及其吊运方法,涉及钢材吊运技术领域,包括底板,底板的底面前后两侧设有若干对U形板,每块U形板的下方均设有L形板,每块L形板的顶面均设有U形座,每块U形板与对应的U形座之间均设有一对铰接杆;位于里侧的铰接杆的顶端部均固设有缺口齿轮,底板的顶面上开设有若干矩形通孔,每个矩形通孔的内部均插设有双面齿条,每根双面齿条均与对应的一对缺口齿轮啮合连接;每块L形板的底部均开设有矩形缺口,每个矩形缺口的内部均设有折板,每块折板的中部均通过销轴与对应的矩形缺口活动铰接。本发明既增加了高硼奥氏体耐热钢吊运时夹持的稳定性,又有效的避免高硼奥氏体耐热钢吊运时发生脱落。
