Patent attributes
A guide frame (1) for an earth drilling apparatus includes a support plate (6) for holding the drive unit (7) and a handle frame (2) having handle sections (17, 18) for holding and guiding the earth drilling apparatus. Operator-controlled elements (19a, 19b, 19c) for controlling the drive unit (7) are arranged in the region of the handle section (18). The handle sections (17, 18) of the handle frame (2) lie in a plane (5) above the support plate (6). The handle frame (2) encloses the drive unit (7) as a closed frame and is connected via a carrier frame (8) to the support plate (6). The carrier plate (8) is fixed to the handle frame (2) via several coupling elements (20). Each coupling element (20) includes a vibration damper (24) which is arranged between the carrier frame (8) and the handle frame (2). In this way, the handle frame is decoupled by the carrier frame from the drive unit with respect to vibration without affecting the bracing of reaction forces via the handle frame.
