Lifting device for dismantling support of supporting beam

The utility model relates to the field of engineering construction demolition equipment, in particular to a lifting device for a support beam demolition support, which comprises a lifting mechanism and a lifting driving mechanism, the lifting device is arranged below the support beam demolition support, and the lifting mechanism comprises a plurality of groups of lifting components arranged at the bottom of a main body. Each hoisting assembly comprises a hoisting shaft and a steel wire rope, and the two ends of the steel wire rope are wound around the two ends of the hoisting shaft correspondingly. After the supporting beam dismantling support is installed on a supporting stand column pile, the hoisting mechanism is controlled and driven by the hoisting driving mechanism to achieve hoisting of the supporting beam in a matched mode, and the supporting beam dismantling support is suitable for being used in occasions where supporting beams are dismantled and cut with strict space requirements. 本实用新型涉及工程建筑拆除设备领域，
