The invention discloses an explosionproof internal-combustion forklift truck. The forklift truck comprises an operation and brake system, a dynamical system, a transmission system, an electrical system, an air intake and exhaust system, a heat exchange system and a lifting system, wherein the lifting system is fixedly connected with a truck frame of the explosionproof internal-combustion forklift truck to be used for lifting heavy cargoes; the lifting system comprises forks, a bracket and a hydraulic device; the hydraulic device comprises two stages of hydraulic cylinder assemblies arranged in the front-rear direction; each stage of hydraulic cylinder assemblies comprises a left hydraulic cylinder set and a right hydraulic cylinder set, which are respectively arranged on two sides of the bracket; a flow splitting and baffling structure is arranged at the bottom of an oil cylinder of one of the two hydraulic cylinder sets, and comprises a movable part and a fixed part, which cooperate with each other; the movable part is provided with oil ports; the fixed part is provided with flow baffling walls; the movable part is positioned at the bottom of the movement stroke of a piston rod in the oil cylinder; the piston rod can push the movable part during the movement stroke, so that the flow baffling walls can shield the oil ports. The explosionproof internal-combustion forklift truck disclosed by the invention can effectively solve the technical problems that a lifting system of a conventional internal-combustion forklift truck is liable to shake during working, and the like.
