Abstract

A lifting station for vertically moving an object, in particular a vehicle body, in a surface treatment installation includes a fixed support structure and a vertically movable lifting cradle which is supported on the support structure and on which at least one conveying device is arranged. Energy for actuating the conveying device can be stored in an energy accumulator arranged on the lifting cradle. In this way, a trailing cable which supplies the conveying device with energy in different lifting positions is not required.

Claims

1. Lifting station for vertically moving an object, in particular a vehicle body, in a surface treatment installation, comprising a fixed support structure, a vertically movable lifting cradle which is supported on the support structure and on which at least one conveying device is permanently attached arranged, an energy accumulator permanently attached arranged on the lifting cradle, wherein energy for actuating the conveying device can be stored on the energy accumulator, and an energy generating device fixed to the lifting cradle, which energy generating device obtains energy from a relative motion between the support structure and the lifting cradle during movement thereof.

2. Lifting station according to claim 1, characterised by a fixed charging station for charging the energy accumulator.

3. Lifting station according to claim 2, characterised in that the charging station includes at least one energy transfer device with which energy can be transferred to the energy accumulator in at least one predefined lifting position of the lifting cradle.

4. Lifting station according to claim 3, characterised in that the energy transfer device includes a fixed electrical contact and a movable electrical contact which is arranged on the lifting cradle and which cooperates with the fixed contact in the at least one predefined lifting position of the lifting cradle.

5. Lifting station according to claim 3, characterised in that the energy transfer device makes possible inductive transfer of electrical energy.

6. Lifting station according to claim 5, characterised in that the energy transfer device includes a first, fixed induction loop and a second induction loop arranged on the lifting cradle.

7. Lifting station according to claim 1, characterised in that the energy is electrical energy.

8. Lifting station according to claim 7, characterised in that the energy transfer device includes a fixed electrical contact and a movable electrical contact which is arranged on the lifting cradle and which cooperates with the fixed contact in the at least one predefined lifting position of the lifting cradle.

9. Lifting station according to claim 8, characterised in that the energy accumulator is a storage battery.

10. Lifting station according to claim 7, characterised in that the energy transfer device makes possible inductive transfer of electrical energy.

11. Lifting station according to claim 10, characterised in that the energy transfer device includes a first, fixed induction loop and a second induction loop arranged on the lifting cradle.

12. Lifting station according to claim 11, characterised in that the energy generating device includes an electric generator.

13. Lifting station according to claim 12, characterised in that the electric generator is a roller dynamo.

14. Lifting station according to claim 1, characterised in that the energy generating device includes an electric generator.

15. Lifting station according to claim 14, characterised in that the electric generator is a roller dynamo.

16. Lifting station according to claim 1, characterised in that the energy accumulator is a storage battery.

17. Lifting station for vertically moving an object, comprising

a) a fixed support structure,

b) a vertically movable lifting cradle which is supported on the support structure,

c) a conveying device which is permanently attached on the lifting cradle,

d) an energy accumulator which is permanently attached on the lifting cradle, wherein energy for actuating a roller drive is stored on the energy accumulator, and

e) a roller dynamo which is permanently arranged on the lifting cradle, wherein the roller dynamo

obtains energy from a relative motion between the support structure and the lifting cradle during movement thereof,

comprises a roller that bears against the support structure and is rotated if the roller dynamo moves vertically along the support structure, and

is configured to load the energy accumulator with the obtained energy.
