Protective device for heat-resistant and high-temperature-resistant nickel-based alloy welding wire

The invention relates to the technical field of welding wire protection, in particular to a heat-resistant and high-temperature-resistant nickel-based alloy welding wire protection device which comprises a plurality of stacked protection modules, cushion frames are arranged at the tops of the protection modules, the protection modules comprise storage boxes, and the top faces of the storage boxes make contact with the bottom faces of the cushion frames at the tops of the storage boxes. A plurality of protection boxes are arranged in the storage box, buffering pads are fixedly connected to the inner side faces of the protection boxes, and supporting mechanisms are fixedly connected to the two side faces of the storage box. According to the storage box, the sliding rod is slidably connected to the inner side face of the fixing rod, an adjusting lead screw can rotate, the adjusting lead screw drives the fixing rod to move upwards relative to the sliding rod, the storage box is lifted, at the moment, other storag
