AI Technical Summary
Technical Problem
The buckets of existing electric shovel excavators lack a power supply device, which restricts the movement of the buckets and makes the pipelines prone to interference or bending, affecting their service life.
Method used
The power unit, which combines friction-type pipeline with a winch, uses friction to drive the pipeline in and out. Combined with a guide and sprocket mechanism, it ensures that the pipeline moves synchronously with the shovel arm, avoiding interference and bending.
Benefits of technology
This technology enables power supply to the bucket, avoids pipeline interference and bending, extends pipeline lifespan, and reduces maintenance costs.

Abstract
This invention discloses a power device for supplying power to the bucket of an electric shovel excavator and its method of use. The power device includes: an internal power element for outputting power; a bucket-end actuator connected to the internal power element via a friction-type pipeline, the bucket-end actuator driving the bucket to perform actions; and a winch located adjacent to the internal power element, the winch being connected to the friction-type pipeline. When the friction-type pipeline moves, the friction-type pipeline drives the winch to rotate, thereby retracting or extending the friction-type pipeline. The power device can transmit power and prevent damage to the pipeline.
