Telescopic lifting unit
A telescopic lifting unit with a first segment, a second segment, and a third segment. The first and second segments may be displaced relative to one another, and the second and third segments may be displaced relative to one another. The first and second segments may be moved relative to one another by a motor unit, and the second and third segments may be moved relative to one another by a cable hoist.
1. A telescopic lifting unit, comprising:
a first segment, a second segment, and a third segment;
said first and second segments being mounted for displacement relative to one another;
said second and third segments being mounted for displacement relative to one another;
a motor unit configured to move said first and second segments relative to one another, said motor unit being configured to interact with a spindle to convert a rotational movement of a motor of said motor unit into a translational movement between said first and second segments; and
a cable hoist configured to move said second and third segments relative to one another.
2. The telescopic lifting unit according to claim 1 , configured as a part of a mobile medical apparatus.
3. The telescopic lifting unit according to claim 1 , incorporated into a mobile X-ray apparatus.
4. The telescopic lifting unit according to claim 3 , wherein one of said first, second, or third segments is configured to have an X-ray head fastened thereto.
5. The telescopic lifting unit according to claim 3 , wherein said one of said first, second, or third segments forms a load-bearing segment having a linear guide for displacing the X-ray head.
6. The telescopic lifting unit according to claim 1 , wherein one of said first, second, or third segments is configured to have a load fastened thereto.
7. The telescopic lifting unit according to claim 6 , wherein said one of said first, second, or third segments forms a load-bearing segment having a linear guide for displacing the load.
8. The telescopic lifting unit according to claim 1 , wherein a movement of said first and second segments relative to one another, and a movement of said second and third segments relative to one another, are synchronized.
9. The telescopic lifting unit according to claim 1 , wherein said motor unit has a first displacement speed and said cable hoist has a second displacement speed, and wherein the first displacement speed is greater than the second displacement speed.
10. The telescopic lifting unit according to claim 1 , wherein said motor unit and/or said cable hoist has a weight compensation device.
11. The telescopic lifting unit according to claim 1 , wherein said cable hoist has a weight compensation device adapted to receive a cable of said cable hoist.
12. The telescopic lifting unit according to claim 1 , further comprising a force sensor.
