Description

technical field [0001] The invention belongs to the technical field of hydraulic machine manufacturing, in particular to a bolt-type safety device for a hydraulic machine. Background technique [0002] When overhauling equipment or correcting molds, the operator usually needs to enter the interior of the press to work, which poses a safety hazard caused by the fall of the press slider. In addition to the support of the hydraulic system, general equipment is also equipped with mechanical safety bolts. At present, the forms of safety bolts include rotary type and folding type. The above-mentioned type of safety bolt is generally controlled by more complicated electrical components or hydraulic components, and the structure is more complicated, limited by the space during installation, and there are many fault points, that is, the pipeline connection is complicated, oil leakage and other phenomena are prone to occur, and Increased maintenance costs.
