[0004] The utility model is realized by adopting the following technical scheme: A hoisting and fork-lifting device with high degrees of freedom, characterized in that it includes a vertical rod, a horizontal rod and a slider assembly. The vertical rod is vertically arranged and slidably matched with the slider assembly. The horizontal rod is horizontally arranged and slidably matched with the slider assembly. A pulley disc is arranged at the top of the vertical rod. The pulley disc is connected to the slider assembly through a steel wire rope. By winding the steel wire rope on the pulley disc, the slider assembly is pulled to slide up and down along the vertical rod. Fork arms and handrails II are respectively connected to both ends of the horizontal rod. The workpiece to be handled is fork-lifted by the fork arms, and the horizontal rod is controlled to move back and forth and rotate horizontally through the handrails II.

[0005] Further, two horizontal rods are provided and arranged on both sides of the vertical rod.

[0006] Further, the slider assembly includes three groups of linear bearings. One group is vertically arranged and slidably matched with the vertical rod, and the other two groups are horizontally arranged on both sides of the vertically arranged linear bearings and slidably matched with the horizontal rod.

[0007] Further, a reduction motor is arranged on the pulley disc. The pulley disc is driven by the reduction motor to wind the steel wire rope. The pulley disc is rotatably connected to the vertical rod.

[0008] Further, the lower end of the vertical rod is connected to a movable flatbed truck.

[0009] Further, a lower fixing block is arranged at the front end of the movable flatbed truck, and a handrail I is arranged at the rear end. An upper fixing block is also arranged at the upper end of the vertical rod. The upper fixing block and the lower fixing block face the same direction. The entire fork-lifting device is fixed through the upper fixing block and the lower fixing block.

[0010] Further, there are three sector-shaped grooves on the upper fixing block, and there are two waist-shaped grooves on the lower fixing block.

[0011] The beneficial effects of the lifting and picking device with high degrees of freedom according to the present utility model include:

[0012] Reducing labor intensity: The automated operation reduces the labor intensity of manual handling.

[0013] Improving safety: Reducing manual operations reduces safety risks.
