The invention discloses a lifting type dust-free wall surface grinding machine for decoration engineering, and relates to the technical field of decoration engineering machinery. The lifting type dust-free wall surface grinding machine for decoration engineering comprises a working bottom plate, wherein an adjusting structure, a lifting mechanism, a grinding mechanism and a dust removal mechanism are arranged above the working bottom plate. According to the lifting type dust-free wall surface grinding machine for decoration engineering, a second motor, a rotating shaft, a first umbrella-shaped gear, a fixing plate, a hollow rotating rod, a second umbrella-shaped gear, a mounting vertical plate, a mounting block, a bolt, a nut, a grinding plate, a grinding disc and a connecting rod are used in cooperation, a wall surface is ground, a grinding area of the device is large, the wall surface grinding efficiency is improved, meanwhile, a grinding disc is convenient to mount and dismount, then the grinding disc is convenient to replace, the situation that the grinding effect of the grinding disc is reduced due to long-time use of the grinding disc is prevented, the grinding effect is guaranteed, and popularization and use are facilitated.
