[0025] When in use, when it is necessary to adjust the height of the arm body 24 itself according to the terrain, the motor 5 is started, and the output end of the motor 5 rotates, driving the No. 1 gear 6 to rotate, and then driving the No. 2 gear 7 to rotate through meshing transmission. The rotation of the No. 2 gear 7 will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the No. 1 bearing seat 8 is limited by the two guide rods 9, when the threaded rod 4 rotates, the No. 1 bearing seat 8 will move up and down, thereby driving the arm body 24 on the No. 1 bearing seat 8 to adjust the height. When the motor 5 rotates, the rotation of the No. 1 gear 6 will drive the open sleeve 10 to rotate, and the limit slider 12 and the The limit of the opening drives the slide bar 11 to rotate, and the No. 2 bearing seat 14 moves up and down with the slide bar 11, which will not affect the rotation of the opening sleeve 10 with the slide bar 11.

[0027] During use, when the height and angle of the robotic arm are adjusted, the lifting and lowering of the output end of the robotic arm is completed by controlling the hydraulic cylinder 22. The output end of the hydraulic cylinder 22 controls the moving block 23 to slide on the guide rod 21, thereby causing the support rod 25 to swing. The support rod 25 causes the arm body 24 to swing, thereby causing the output end of the arm body 24 to be lifted and lowered, making the robotic arm more flexible, applicable to more usage scenarios, and making transportation more efficient.

[0028] The detailed working process of the utility model is as follows:

[0029] When in use, when it is necessary to adjust the height of the arm body 24 itself according to the terrain, the motor 5 is started, and the output end of the motor 5 rotates, driving the No. 1 gear 6 to rotate, and then driving the No. 2 gear 7 to rotate through meshing transmission. The rotation of the No. 2 gear 7 will drive the threaded rod 4 to rotate. When the threaded rod 4 rotates, since the No. 1 bearing seat 8 is limited by the two guide rods 9, when the threaded rod 4 rotates, the No. 1 bearing seat 8 will move up and down, thereby driving the arm body 24 on the No. 1 bearing seat 8 to adjust the height. When the motor 5 rotates, the rotation of the No. 1 gear 6 will drive the open sleeve 10 to rotate, and the limit slider 12 and the The position limit of the opening drives the slide bar 11 to rotate, and the No. 2 bearing seat 14 moves up and down with the slide bar 11, which will not affect the rotation of the opening sleeve 10 with the slide bar 11. When the slide bar 11 rotates, the No. 3 gear 17 is driven to rotate, and then the No. 4 gear 18 and the bearing column 15 are driven to rotate through meshing transmission, and then the No. 3 bearing seat 16 is driven to rotate, and the angle of the arm body 24 is adjusted. The height and angle are adjusted by a motor 5. After obtaining a suitable angle and a relatively suitable height, the lifting component is used to enable the transport vehicle to cope with more terrains and also be suitable for goods of more sizes.

[0030] During use, when the height and angle of the robotic arm are adjusted, the lifting and lowering of the output end of the robotic arm is completed by controlling the hydraulic cylinder 22. The output end of the hydraulic cylinder 22 controls the moving block 23 to slide on the guide rod 21, thereby causing the support rod 25 to swing. The support rod 25 causes the arm body 24 to swing, thereby causing the output end of the arm body 24 to be lifted and lowered, making the robotic arm more flexible, applicable to more usage scenarios, and making transportation more efficient.
