Automatic electric pole climbing operating platform

The invention discloses an automatic electric pole climbing operating platform comprising a gear rack sliding climbing mechanism, a buckle locking mechanism, a work platform, and a hoop rotating mechanism. The gear rack sliding climbing mechanism comprises an inner sliding arm, an outer sliding sleeve, a driving device, and climbing unidirectional guide wheels. The inner sliding arm is inserted into the outer sliding sleeve from the top of the outer sliding sleeve and is in sliding connection with the outer sliding sleeve. The driving device drives the inner sliding arm to slide. The top of the inner sliding arm, the top end and the bottom end of the outer sliding sleeve are all equipped with the climbing unidirectional guide wheels. The climbing unidirectional guide wheels are in sliding connection with an electric pole. The buckle locking mechanism locks the inner sliding arm and the outer sliding sleeve or separates the inner sliding arm and the outer sliding sleeve from the electric pole. The work platform is fixed to the outer sliding sleeve and tightly holds or loosens the electric pole by means of the hoop rotating mechanism. The automatic electric pole climbing operating platform helps a worker improve power equipment installation and maintenance work efficiency, and reduces the labor intensity and the accident risk of the worker.
