The positional relationship and connection relationship of the above device components are as follows: steel nail 3, gunpowder pack 4, firing pin 5, clamp 6, spring 7, spring clamp groove 17, electromagnet 16 are successively arranged in the inner cavity of the body 1; The fastening nut 2 and the distance adjusting nut 8 are installed at both ends of the body 1 respectively, and are fastened with turnbuckles; the electromagnet 16 is connected with the switch control module 10 through the power wire 14; the switch control module 10 is connected with the signal processing module 11 and the signal receiving module The modules 12 are connected and powered by the power supply box 13; the sealing hub 9 is connected to the body 1 through bolts; the operating handle 15 is located outside the sealing hub 9 and connected to the end of the striker 5; the power-on button 18, reset button 19, and firing button 20 are installed 1. The button battery 23 is connected with the remote sensing control module 21 through a circuit board and installed inside the remote control shell 22 . the

A remote-controlled continuous casting slab nailing method using the above-mentioned device. According to the measurement plan during the nailing, the nailing device is fixed on the side of the continuous casting slab to be measured before starting. If the measurement object is a billet or a slab Align the guide hole on the front end of the nail shooting device vertically with the measurement surface of the continuous casting slab; if the measurement object is a round billet, align the guide hole on the front end of the nail shooting device vertically with the tangential direction of the measurement point. Five minutes before the start of firing, turn on the power of the nail shooting device and evacuate the operator and field personnel to a safe area. One minute before the start of firing, turn on the power switch of the remote control, count down, and wait for the firing command; when the firing time is reached, press the firing button on the remote control to fire the nailing device, and the steel nails enter the interior of the billet. Mark the firing point, disassemble the nailing device, and finish the nailing. the
