The telescopic pallet fork device comprises a telescopic pallet fork and a driving component, and the driving component comprises a shell, a driving motor, a threaded lead screw, an inner threaded sleeve, an outer threaded sleeve shaft and a spline shaft. The first gear and the second gear are meshed to transmit power to the threaded lead screw to drive the threaded lead screw and the spline shaft to rotate. The threaded lead screw rotates to drive the internal threaded sleeve to rotate and axially move; the spline shaft rotates to drive the external thread barrel shaft to rotate and axially move, so that the telescopic pallet fork stretches out and draws back. The parallel nested structure generates a driving stroke superposition effect to form a two-stage stroke-extending telescopic structure, and the two-stage stroke-extending telescopic structure is long in working stroke, light in weight, energy-saving, thin in thickness, compact in structure and high in space utilization rate. The first and second thread sections form a positive and negative thread structure, the acting force of the driving motor is amplified, self-locking is formed, and the moving precision is high. The telescopic pallet fork takes and places goods and provides a linear guiding effect for the driving component. The overall hollow structure is matched with the spline shaft, goods of different weights can be effectively borne, and bending resistance is good.

    本发明涉及伸缩货叉装置及二向穿梭车,包括伸缩货叉和驱动部件,驱动部件包括壳体、驱动电机、螺纹丝杆、内螺纹套筒、外螺纹筒轴、花键轴。第一、二齿轮啮合将动力传递至螺纹丝杠,带动螺纹丝杠和花键轴转动;螺纹丝杠转动,带动内螺纹套筒转动和轴向移动;花键轴转动带动外螺纹筒轴转动和轴向移动,使伸缩货叉伸缩。并联嵌套结构产生驱动行程叠加作用,形成二级增程伸缩结构,工作行程长、轻量化、节能,厚度薄、结构紧凑、空间利用率高。第一、二螺纹段形成正反螺纹结构,放大驱动电机作用力、形成自锁,移动精度高。伸缩货叉取放货品,为驱动部件提供直线导向作用。整体中空结构配合花键轴,能够有效承载不同重量货品,抗弯性能好。
