Bridge fusion cutting device

The invention relates to a bridge fusion cutting device. According to the bridge fusion cutting device, a handle, a rotary lifting assembly, a heating assembly, a fuse rod and a protection assembly are arranged, the protection assembly is used for achieving the heat preservation and protection effects on the fuse rod, the safety of the device can be effectively improved, a bridge does not need tobe dismantled in a hard-to-hard mode such as crushing and cutting, noise can be reduced. No wind and dust are generated, and environmental pollution is reduced. And the portable engine is small and flexible, is not limited by a power supply, and can randomly cut any position of the bridge. And the telescopic function of the rotary lifting assembly is arranged, and the cutting length of the tungsten alloy bar can be freely changed according to the cutting position to meet the better cutting requirement. The tungsten alloy bar can be heated rapidly, temperature control over the tungsten alloy bar can be achieved, the te
