Scissor-fork type lifting platform stable in operation

The invention discloses a scissor-fork type lifting platform stable in operation. The scissor-fork type lifting platform comprises a base, lifting mechanisms and a platform main body, wherein the base and the platform main body are in parallel arranged at an interval in a vertical direction; the base is positioned below the platform main body; the lifting mechanisms are arranged between the base and the platform main body; each lifting mechanism comprises a lower supporting leg, a lower guide supporting leg, an upper guide supporting leg, an upper supporting leg and a hydraulic oil cylinder; the lower end of the lower supporting leg is mounted on the base in a rotary mode; the lower end of the upper supporting leg is embedded into the lower end of the lower supporting leg; the upper supporting leg and the lower supporting leg are connected in the rotary mode; the upper end of the upper supporting leg is connected with the bottom of the platform main body in the rotary mode; the tail part of the hydraulic oil cylinder is mounted on the upper part of the lower supporting leg; the head part of the hydraulic oil cylinder is connected with the upper part of the upper supporting leg; the hydraulic oil cylinder is connected with a power unit through a high-pressure oil tube; and the two sets of lifting mechanism are arranged in a horizontal direction in parallel at intervals between the base and the platform main body. The scissor-fork type lifting platform is stable in operation and high in safety.
