Abstract
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.
Description
technical field [0001] The invention relates to the technical field of vehicle equipment, and more specifically, relates to an explosion-proof internal combustion forklift. Background technique [0002] At present, explosion-proof working vehicles, especially explosion-proof forklifts, can be widely used in petroleum, chemical, pharmaceutical, textile, military, paint, pigment, coal and other industrial sectors as well as ports, railways, freight yards, warehouses and other places containing explosive mixtures. Forklifting, hoisting, and handling operations are especially suitable for loading, unloading, and stacking operations in narrow caverns, workshops, docks, tunnels and other places that require high maneuverability of vehicles. Its application range is very wide. [0003] However, explosion-proof battery counterbalanced forklifts are developing rapidly in domestic explosion-proof forklifts, but research on explosion-proof internal combustion counterbalanced forklifts ...
