Abstract

The invention relates to a safety remote-control ignition rod, in particular to a safety appliance which is used for ensuring the body security of operation technicists during metal welding by use of an exothermic welding flux, and belongs to the technical field of welding. The safety remote-control ignition rod comprises a resistance wire, a guide-in pipe, insulating blocks, a first wire, a second wire and a plug connector, wherein the first wire and the second wire are mounted in the guide-in pipe in the length direction; the right end part of the first wire is connected with the right end part of the second wire through the resistance wire; the insulating blocks are arranged between the first wire and the second wire; the plug connector is arranged on the left side of the left end part of the guide-in pipe; and the left end part of the first wire and the left end part of the second wire are inserted into the plug connector. The safety remote-control ignition rod is simple, safe and reasonable in structure, takes the resistance wire as the main element, realizes 'direct' ignition, and ensures that the technicists are prevented from being injured by jetting during reaction of the exothermic welding flux; and hands of the technicists can be moved from 8 cm away from a die to a safe operation area 1-5 m away from the die.

Description

technical field [0001] The invention relates to a safety type remote control ignition rod, in particular to a safety appliance used for the thermite flux to ensure the personal safety of technicians when welding metal, and belongs to the field of welding technology. Background technique [0002] At the end of the nineteenth century, with the development of the smelting industry and the chemical industry, the thermite welding method using thermite as a heat source appeared. This technology has the characteristics of simple equipment, less investment, fast welding operation, good welding effect, no need for high-power power supply during welding, and easy welding operation. It is especially suitable for field construction operations. [0003] Over the past few decades, the aluminothermic welding technology has developed from the original seamless welding of rails to the welding of copper core cables and cables, the welding of copper core cables on cathodic protection and steel...
