Abstract
A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis and a drive coupled to the two wheels. A sensor serves for detecting a contact pressure of the holder, the contact pressure acting in the direction of gravitational force. The control station activates the propulsion system depending on the detected contact pressure.
Claims5
A self-aligning tool guide, comprising:
- a holder for securing a portable power tool for working on a ceiling;
- a lifting mechanism on which the holder is mounted, wherein the lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis;
- a self-balancing chassis which has two wheels on a wheel axis and a drive coupled to the two wheels;
- wherein the lifting mechanism is mounted rigidly on the self-balancing chassis;
- a sensor for detecting a contact pressure of the holder, wherein the contact pressure acts in a direction of a gravitational force;
- and
- a control station which adapts a propulsion speed of the propulsion system depending on the detected contact pressure.
