The invention relates to safety valve transferring equipment, in particular to a safety valve clamping and transferring trolley. The trolley comprises a trolley frame. A supporting plate is fixed to a trolley frame base plate. A left swing arm and a right swing arm are hinged to the front end of the supporting plate. Corresponding lifting blocks are fixed to the clamping ends of the left and right swing arms respectively. The other ends of the left and right swing arms are each connected with a connecting rod. The two connecting rods are connected with a sliding block nut at the same time. A rocker arm is rotationally arranged at the rear end of the supporting plate and fixedly connected with a lead screw. The lead screw is in threaded connection with the sliding block nut. A hydraulic cylinder is fixed to the rear end of the trolley frame. A base is fixed to the lower portion of the hydraulic cylinder. A control rod is connected to a connecting wing plate of the hydraulic cylinder. The control rod can move up and down along with an installation hole of the connecting wing plate. A spring used for resetting the control rod is arranged on the base. By the adoption of the transferring trolley, safety valves can be transferred more conveniently and rapidly, the labor intensity of operators is lowered, and the working efficiency is improved.
