The invention discloses a sliding wheel type steel wire rope dragging and lifting portal frame system of an electric forklift, and belongs to the technical field of forklifts. The system comprises a bottom sliding double-movable-wheel mechanism, a main power transmission system, a top sliding double-fixed-wheel mechanism, a steel wire rope, an inner portal frame, an outer portal frame, a pallet fork, a position control system and the like. According to the system, on the basis of a conventional forklift assembly, the steel wire rope, the top sliding double-fixed-wheel mechanism, a double-shaftmotor, a double-domain variable-torque roller, the bottom sliding double-movable-wheel mechanism and the like drag and pull a portal frame of the electric forklift to lift so as to achieve lifting motion of the pallet fork; and the problems that an existing hydraulic drive forklift lifting system is large in weight, high in energy consumption, large in number of parts and high in production and maintenance cost are solved, and the purposes of stable portal frame lifting, light weight, low energy consumption, simple structure, convenient control and easy maintenance are achieved.

    一种电动叉车滑移轮式钢丝绳拖曳举升门架系统,属于叉车技术领域,包括底部滑移双动轮机构、主动力传输系统、顶部滑移双定轮机构、钢丝绳、内门架、外门架、货叉、位置控制系统等组成。本发明在常规叉车组件的基础上,通过钢丝绳、顶部滑移双定轮机构、双轴电动机、双域变力矩滚筒、底部滑移双动轮机构等拖曳牵引电动叉车门架的举升来实现货叉的升降运动。本发明解决了当前液压驱动叉车举升系统重量大、能耗高、零件多、生产和维修成本贵的问题,实现门架举升平稳、质量轻便、能耗降低、结构简单、控制方便、维修容易的目的。
