[0031] To make the purpose, technical solution and advantages of the present technical solution clearer and more understandable, the present technical solution will be further described in detail below in combination with specific embodiments. It should be understood that these descriptions are exemplary and not intended to limit the scope of the present technical solution.

[0032] As Figure 1 shown, the main body of a shaft arm picking trolley structure in this embodiment is a vehicle body, which includes a vertical vehicle body 11 and a horizontal vehicle body 12. The vertical vehicle body 11 and the horizontal vehicle body 12 are integrally formed. The vertical vehicle body 11 is located in front of the horizontal vehicle body 12. The front of the vertical vehicle body 11 is provided with an inclined surface, and an operation panel 20 is installed on this inclined surface. The top of the vertical vehicle body 11 is provided with a warning light 14, which can flash lights during vehicle operation to give a light warning to surrounding personnel. Emergency stop buttons 15 are provided on both the left and right sides of the vertical vehicle body 11. In case of an accident, surrounding personnel can press the emergency stop button 15 urgently to make the shaft arm picking trolley structure stop immediately.

[0033] The top surface of the main body of the horizontal vehicle body 12 is a plane, and an axle arm transport mechanism 40 is arranged on its upper part. A circle of anti-collision safety touch edge 13 is arranged near the bottom of the outer periphery of the horizontal vehicle body 12, and the anti-collision safety touch edge 13 can prevent objects from being rolled under the vehicle body.

[0034] like Figure 2 As shown, a first laser radar 16 is arranged near the top of the front of the vertical body 11, a third radar is arranged at the height of the lower end of the vertical body 11 near the horizontal body 12, and a second laser radar 17 is arranged on the right front side and the left rear side of the horizontal body 12. The above-mentioned first laser radar 16, second laser radar 17, and third laser radar 19 can detect the surrounding environment of the car in real time, and can achieve visual recognition effect. If there are debris on the route of the car, the car can stop in time or make evasive actions. A speaker opening 18 is also arranged at the front of the horizontal body 12, and a speaker is arranged in the horizontal body 12 corresponding to the speaker opening 18. The speaker can play prompt audio to issue a sound warning to the surrounding people.

[0035] The operation panel 20 is provided with a warning light 21, a button 22, a touch screen 23, an indicator light 24 and a USB interface 25. The warning light 21 and the indicator light 24 can display the running status of the vehicle by light, and the button 22 and the touch screen 23 can cooperate with each other to set the running path, running action, and check the running log of the vehicle. The USB interface 25 can be inserted into the corresponding storage to input or export the corresponding file so as to set the running mode and execute the action.

[0036] like Figure 3 As shown, an arm transport mechanism 40 and an organ shield 110 are provided on the back of the vertical vehicle body 11. When the arm transport mechanism 40 moves up and down, the organ shield 110 ensures the sealing of the internal operating mechanism of the arm transport mechanism 40, thereby preventing debris from entering the interior of the arm transport mechanism 40 and affecting the normal operation of the arm transport mechanism 40.

[0037] like Figure 4 As shown, the driving mechanism includes an active driving assembly 32 and a driven wheel 33 arranged at the bottom of the horizontal body 12. There are two sets of active driving assemblies 32, which are arranged side by side in the middle of the bottom surface of the horizontal body 12. There are four sets of driven wheels 33, which are arranged at the four corners of the bottom surface of the horizontal body 12. The middle of the bottom surface of the horizontal body 12 has an AGV magnetic navigation sensor 31, and the front and rear of the AGV magnetic navigation sensor 31 have landmark sensors 34. The front of the bottom surface of the horizontal body 12 has a charging module 35.

[0038] Specifically, the four driven wheels 33 are distributed at the four corner positions of the vehicle body contour at the bottom of the vehicle body, ensuring the stability of the AGV operation; a landmark sensor 34 is provided at the center position of the bottom of the vehicle body, which can identify the landmarks on the ground and execute corresponding action instructions; AGV magnetic navigation sensors 31 are respectively installed in front of and behind the landmark sensor 34 for precise positioning at the end of the navigation point; a charging module 35 is provided in front of the AGV magnetic navigation sensor 31, enabling the AGV to automatically charge after completing the task.

[0039] Combined Figure 4 with Figure 5 As shown, the main body of the shaft arm handling mechanism 40 is a fork arm 41. The root of the fork arm 41 is connected to the moving end of the vertical lifting drive device. The front end of the fork arm 41 is a chasing platform-shaped guiding head 43. A buffer pad 42 is sleeved on the outer ring surface of the root of the fork arm 41, and a blocking block 44 is arranged at a position near the front of the outer ring surface of the fork arm 41.

[0040] The buffer pad 42 is used to make the material in soft contact with the fork arm 41 when the fork arm 41 forks the material, improving the docking accuracy and safety; the guiding head 43 amplifies the tolerance when the fork arm 41 docks with the material, facilitating the fork arm 41 to fork the material. After the fork arm 41 completes the docking with the material, the blocking block 44 will open to prevent the material from falling off.

[0041] In a feasible embodiment, the above-mentioned vertical lifting drive device can be any linear drive mechanism, such as a lead screw slider mechanism, a gear rack mechanism, etc. Preferably, it is a lead screw slider mechanism, which can provide a greater torque and control the slider displacement more precisely. For example, in this embodiment, the vertical lifting drive device adopts a lead screw slider mechanism, and the root of the fork arm 41 is correspondingly installed on the slider of the lead screw slider mechanism.

[0042] In a feasible embodiment, the blocking block 44 can be an executing component of any electric pin component. It is only necessary that the blocking block 44 can be controllably extended out of the fork arm 41 or retracted into the fork arm 41. One or more blocking blocks 44 can be adopted. The electric pin component is prior art and will not be elaborated here.

[0043] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present technical content, many changes can be made in the specific implementation manners and application scopes. As long as these changes do not deviate from the concept of the present utility model, they all fall within the protection scope of this patent.
