This completely eliminates vibration caused by rolling wheels or uneven ground, ensuring that the robot body is absolutely firmly in contact with the ground.
[0076] Strong ground anchoring: The multiple inverted cone-shaped positioning plugs 5023d set at the bottom of the lower chassis 5023b can be effectively embedded in the ground, providing strong anti-slip and anti-pullout forces. It is particularly suitable for working in working conditions with a certain degree of softness or requiring resistance to lateral forces, such as welding vibration.
[0077] 3. Convenient mode switching and restoring mobility: After the operation is completed, the lower supporting hydraulic cylinder 5023a contracts, driving the lower chassis 5023b and the positioning plug 5023d to rise off the ground.
[0078] At the same time, the rolling wheel 403 contacts the ground again, and the robot immediately recovers its mobility, facilitating a quick transition.
[0079] 4. Efficient automatic cleaning and maintenance function: After the support mechanism is retracted and the positioning plug is pulled out of the ground, the lower vibrator 5023c is started.
[0080] The vibrator drives the lower chassis 5023b and the positioning insert 5023d to vibrate at a high frequency.
[0081] This vibration can effectively shake off and remove the dirt or debris stuck in the gap of the inverted cone-shaped positioning plug.
[0082] This design significantly reduces the need for manual cleaning, prevents soil accumulation from affecting the next positioning effect or mechanism operation, and improves the self-maintenance and long-term reliability of the equipment.
[0083] 5. Reasonable structural design and high functional integration: The drive, motor, wheels, stabilizing hydraulic cylinders and support legs are modularly integrated on the base.
[0084] Six equidistant ring designs of stabilizing mechanisms provide balanced support.
[0085] Each outer support plate is connected to two outer support mechanisms, further enhancing the support strength of a single stable point.
[0086] In summary, the key benefits of this design are: It perfectly addresses the core conflicting requirements of mobile robots, such as welding robots: the need for high mobility to reach the work position, yet the need for ultimate operational stability to ensure precision and quality. Through innovative multi-hydraulic leg deployment, ground plug locking, wheel lift-off, and a unique vibration cleaning design, it enables efficient and reliable switching between mobile and stable operating modes, effectively ensuring long-term convenience and stability. It is particularly suitable for industrial applications requiring high ground stability.
