[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. The preferred embodiments in the description are only used as examples, and all other embodiments obtained by those skilled in the art without making any creative work are within the scope of protection of the utility model.

[0021] like Figure 1-Figure 3 As shown, this specific embodiment adopts the following technical scheme: it includes a steel structure support 1, a servo control system 2, a scissor lift 3, a hanger 4, a spring hook device 5 and a horizontal operation mechanism 6; the bottom of the steel structure support 1 is movably connected with the scissor lift 3 by the horizontal operation mechanism 6, the bottom of the scissor lift 3 is connected with the hanger 4, and the four corners of the bottom of the hanger 4 are connected with the spring hook device 5; the servo control system 2 is arranged on the steel structure support 1, and is controlled and connected with the scissor lift 3, the horizontal operation system in the horizontal operation mechanism 6 and the spring hook device 5; the spring hook device 5 includes:

[0022] A mounting plate 5-1, wherein the mounting plate 5-1 is fixed to the bottom of the hanger 4;

[0023] An electric push rod 5-2, wherein the electric push rod 5-2 is fixed on the mounting plate 5-1, and the output end of the electric push rod 5-2 is connected to the top of the hook mounting frame 5-4; a limit switch 5-9 is installed below the electric push rod 5-2, and the limit switch 5-9 is connected to the servo control system 2 for sensing the moving position of the electric push rod 5-2;

[0024] A linear slide rail 5-3, wherein the linear slide rail 5-3 is mounted on a slide rail fixing seat 5-8, the slide rail fixing seat 5-8 is mounted on the bottom of the hanger 4, and the hook mounting frame 5-4 is fixed on a slider slidably mounted on the linear slide rail 5-3;

[0025] A hook shaft 5-6, wherein the hook shaft 5-6 is movably mounted in the hook mounting frame 5-4, and a compression spring 5-5 is sleeved on the hook shaft 5-6, and a limiting end plate 5-10 is connected to the top of the hook shaft 5-6 to prevent the hook shaft 5-6 from moving away from the hook mounting frame 5-4;

[0027] When using the utility model, after the logistics empty frame transport line transports the empty frame to the empty frame stacking position, the detection system in the servo control system 2 detects that the empty frame is in place, and the control system in the servo control system 2 controls the horizontal operating mechanism 6 to work, driving the scissor lift 3 to run above the empty frame that needs to be hoisted, and then the servo control system 2 controls the scissor lift 3 to descend, thereby driving the spring hook device 5 to descend to the periphery of the empty frame that needs to be hoisted, and then the servo control system 2 is used to control the electric push rod 5-2 to extend, thereby driving the hook 5-7 to move and insert the empty frame, and then the servo control system 2 is used to control the scissor lift 3 to rise, and control the horizontal operating mechanism 6 to operate, and the empty frame is hoisted to the material frame stacking position for placement.
