Steel jump prevention device and method and cooling bed

The invention relates to the cooling bed technology field, in particular to a steel jump prevention device and an application thereof. The main point of the technical scheme is that the steel jump prevention device comprises a fixed bottom seat arranged on a cooling bed, wherein a support is arranged on the top surface of the fixed bottom seat, a pressing plate is movably connected with one end, far away from the fixed bottom seat, of the support, the pressing plate is used for blocking a steel piece excessively popped out from the cooling bed, and when the rolled piece is thrown to a first tooth of a fixed tooth plate of the cooling bed and the tooth cannot constrain the rolled piece, the rolled piece needs to strike a limiting piece so as to break through blocking of the limiting deviceand jump out, and therefore the rolled piece is prevented from jumping out. The steel jump prevention device has the advantage of preventing the rolled steel piece from jumping. 本发明涉及一种冷床技术领域，更具体地说，它涉及一种防跳钢装置及应用，其技术方案要点是：包括设置
