The invention relates to a dustproof hydraulic device. The dustproof hydraulic device comprises a cylinder body, a piston and a supporting disc, wherein the cylinder body is cylindrical and is vertically arranged; the piston is matched with the cylinder body and is mounted on the cylinder body; the supporting disc and the cylinder body are coaxially arranged, and the supporting disc is fixed to the top end of the piston; a gap is formed between the supporting disc and the cylinder body; a hydraulic system is arranged in the cylinder body; a dustproof mechanism is arranged on the supporting disc and located between the supporting disc and the cylinder body; an auxiliary mechanism is arranged on the supporting disc; and the dustproof mechanism comprises a dustproof pipe, a sealing ring, a connecting pipe, a first bearing, a cleaning ring, a power assembly and at least two connecting assemblies. According to the dustproof hydraulic device, the dustproof function is achieved through the dustproof mechanism, in addition, the stability of jacking a spherical object is improved through the auxiliary mechanism, and the cylinder body is prevented from collapsing.
