Drilling device for vertical grounding electrode

The drilling device comprises an engine, a vertical drill rod, a telescopic support and a driving device, the telescopic support comprises an upper support and a lower support, the upper support and the lower support are connected in an up-down sliding mode, and the engine and the upper support are connected in an up-down sliding mode. The driving device drives the upper support to slide up and down along the lower support and drives the engine to slide up and down along the upper support, an output shaft of the engine is coaxially connected with the vertical drill rod, and the vertical drill rod is fixed below the engine. Vertical drilling is mechanized and standardized, one-time forming of deep holes can be achieved, manpower is saved, drilling efficiency is improved, and meanwhile a grounding electrode is prevented from being damaged. The telescopic support is telescopic, the height is shortened in a non-use state, miniaturization of the device is achieved, and carrying is convenient. 本实用新型公开了一种垂直接地极用钻孔装置，
