[0022] This utility model discloses a protective multi-axis controlled robotic arm suitable for oil and gas environments.

[0023] Reference Figure 1-3 A protective multi-axis control robotic arm suitable for oil and gas environments includes a robotic arm body 1 and a protective shell 2. Multiple protective shells 2 are fixedly installed at multiple joint positions of the robotic arm body 1. Inspection ports are provided on both sides of the multiple protective shells 2. A cover plate 4 is provided on the outer side of the inspection port. A sealing gasket is fixedly provided on the side of the cover plate 4 near the protective shell 2 to improve the sealing between the cover plate 4 and the protective shell 2. A rotating rod 3 is rotatably provided inside one corner of the protective shell 2. The two ends of the rotating rod 3 are fixedly connected to the corresponding cover plate 4. Gears 14 are fixedly sleeved on the rod walls at both ends of the rotating rod 3. A rack 13 is meshed on one side of each of the two gears 14. A fixing block 5 is fixedly provided on one side of the protective shell 2. A fixing shell 6 is fixedly provided on the upper side of the fixing block 5.

[0024] Reference Figure 1-3 The fixed shell 6 has a limiting mechanism inside to restrict the movement of the two racks 13. The limiting mechanism includes a U-shaped plate 11 and a sliding rod 8. A slider 7 is slidably arranged inside the fixed shell 6. The sliding rod 8 is fixedly arranged on the upper side of the slider 7, and the upper end of the sliding rod 8 extends to the outer side of the fixed shell 6. The U-shaped plate 11 is fixedly arranged on the upper end of the sliding rod 8. Vertical rods 12 are fixedly arranged at both ends of the upper surface of the U-shaped plate 11. One side of each of the two racks 13 is fixedly connected to the corresponding vertical rod 12. A bolt 10 is threadedly fitted on the lower side wall of the fixed shell 6. One end of the bolt 10 is threadedly locked to the corresponding slider 7. A rotating wheel is fixedly fitted on the outer end of the bolt 10 to facilitate the rotation of the bolt 10. The cross-sections of the fixed shell 6 and the slider 7 are both rectangular, so that the slider 7 cannot rotate, that is, it can slide stably. A spring 9 is fixedly arranged on the upper side of the slider 7. The other end of the spring 9 is fixedly connected to the inner wall of the fixed shell 6 to facilitate the reset of the slider 7.

At the same time, the protective shell 2 has an inspection port, which facilitates the maintenance and repair of the components of the joint of the main body 1 of the robotic arm. When performing maintenance and repair work, loosening the bolt 10 releases the limit on the slider 7, which allows the slider 8 to be pulled upward, causing the U-shaped plate 11 to drive the rack 13 to move. The rack 13 drives the corresponding gear 14 to rotate, which causes the rotating rod 3 to rotate. The rotating rod 3 drives the two side cover plates 4 to rotate, which opens the inspection port for convenient maintenance and repair work.
