Description

Technical Field

[0001] This invention relates to the field of unlocking mechanism technology, specifically to an unlocking mechanism for a tracked power maintenance robot. Background Technology

[0002] The number of unmanned substations is constantly increasing. In these substations, the daily maintenance and troubleshooting of equipment rely on remote control and automation equipment. Power maintenance robots can serve as a key link, working with other automation equipment to complete the remote maintenance of substation equipment.

[0003] In practical use, due to the high cost of substation equipment, padlocks are often required for locking and protection. When power maintenance robots are conducting inspections and maintenance, they may encounter situations where unlocking is necessary. Existing unlocking mechanisms for power maintenance robots are relatively simple. When opening padlocks, they cannot effectively clamp and position the padlocks, which can easily cause the padlocks to shift when inserting the key, making it difficult to insert the key and reducing unlocking efficiency. Some padlocks have special angles, and existing unlocking mechanisms for power maintenance robots are difficult to adjust to adapt to them, which can easily lead to unlocking failures, resulting in robot maintenance failures and requiring manual repairs, increasing maintenance costs.

[0004] Existing power maintenance robots cannot effectively clamp and position padlocks, which can easily cause the padlock to shift when the key is inserted, making it difficult to insert the key, reducing the unlocking speed and slowing down the maintenance efficiency. The unlocking mechanism of existing power maintenance robots cannot adapt to padlocks at special angles, which can easily lead to the inability to unlock, resulting in robot maintenance failure, requiring manual maintenance, and increasing maintenance costs.
