Abstract

A nail punching machine for driving in or pulling out rail spikes comprises a driving mechanism, which is driven by means of an electric drive motor. The electric drive motor is supplied with electric power by means of an accumulator. The nail punching machine is held by an operator by means of at least one handle.

Claims (40)

1. A nail punching machine for one of the group of driving in and pulling out rail spikes of a rail track, the nail punching machine comprising:

at least one handle for holding the nail punching machine;

a driving mechanism with a striking mechanism for driving a rail spike into a tie;

an electric drive motor for driving the driving mechanism;

an accumulator for supplying the electric drive motor with electric power; and

a vibration decoupling device for decoupling vibrations of the at least one handle and the driving mechanism, the vibration decoupling device defining a decoupling plane, which separates a working side from an operating side, the driving mechanism being arranged on the working side, the at least one handle and the accumulator being arranged on the operating side;

wherein no mechanical connections for driving the driving mechanism extend through the decoupling plane.

2. The nail punching machine according to claim 1 , wherein the vibration decoupling device has at least one vibration damper for configuring the decoupling plane between the driving mechanism and the at least one handle.

3. The nail punching machine according to claim 1 , wherein the electric drive motor is arranged on the working side of the decoupling plane.

4. The nail punching machine according to claim 1 , wherein the accumulator is exchangeably mounted to a supporting frame and connected with a handle.

5. The nail punching machine according to claim 1 , wherein a control device is arranged on the operating side of the decoupling plane.

6. The nail punching machine according to claim 1 , wherein, exclusively, lines are running through the decoupling plane.

7. The nail punching machine according to claim 1 , comprising a cooling device for cooling at least one of the group comprising the electric drive motor and the driving mechanism.

8. The nail punching machine according to claim 1 , wherein the electric drive motor is arranged in an upper section of a pipe, turned away from the rail track.

9. The nail punching machine according to claim 1 , wherein the electric drive motor is arranged in a lower section of a pipe, facing the rail track.

10. The nail punching machine according to claim 1 , wherein the striking mechanism is displaceable in an exclusively linear manner in an axial direction of the nail punching machine.

11. The nail punching machine according to claim 1 , wherein the decoupling plane is free of mechanical connections for driving the driving mechanism.

12. A nail punching machine for one of the group of driving in and pulling out rail spikes of a rail track, the nail punching machine comprising:

a handle for holding the nail punching machine;

a driving mechanism comprising a striking mechanism for driving a rail spike into a tie;

an electric drive motor for driving the driving mechanism;

a housing, the driving mechanism and the electric drive motor being arranged in an interior of the housing;

an accumulator for supplying the electric drive motor with electric power;

a supporting frame connected to the handle and the accumulator; and

a vibration decoupling device for decoupling vibrations of the handle and the driving mechanism, the vibration decoupling device defining a decoupling plane, the decoupling plane separating a working side from an operating side, the driving mechanism being arranged on the working side, the handle and the accumulator being arranged on the operating side, the vibration decoupling device comprising at least one vibration damper, a first mounting element mounted to the supporting frame and a second mounting element mounted to the housing, the at least. one vibration damper being in contact with the first mounting element and the second mounting element;

wherein no mechanical connections for driving the driving mechanism extend through the decoupling plane.

13. The nail punching machine according to claim 12 , wherein at least a portion of the handle is arranged laterally on the supporting frame.

14. The nail punching machine according to claim 12 , wherein the vibration decoupling device comprises another vibration damper, the another vibration damper connecting the handle to the first mounting element.

15. The nail punching machine according to claim 12 , wherein the decoupling plane is free of mechanical connections for driving the driving mechanism.

16. A nail punching machine for one of the group of driving in and pulling out rail spikes of a rail track, the nail punching machine comprising:

a handle for holding the nail punching machine;

a driving mechanism comprising a striking mechanism for driving a rail spike into a tie;

an electric drive motor for driving the driving mechanism;

a housing comprising a housing interior space, the driving mechanism and the electric drive motor being arranged in the housing interior space;

an accumulator for supplying the electric drive motor with electric power; and

a vibration decoupling device for decoupling vibrations of the handle and the driving mechanism, the vibration decoupling device defining a decoupling plane, the decoupling plane separating a working side from an operating side, the driving mechanism being arranged on the working side, the handle and the accumulator being arranged on the operating side, the vibration decoupling device comprising at least one vibration damper, the at least one vibration damper being located at a spaced location from the housing;

wherein no mechanical connections for driving the driving mechanism extend through the decoupling plane.

17. The nail punching machine according to claim 16 , further comprising:

a supporting frame connected to the handle and the accumulator, the vibration decoupling device comprising a first mounting element mounted to the supporting frame and a second mounting element mounted to the housing, the at least one vibration damper being in contact with the first mounting element and the second mounting element.

18. The nail punching machine according to claim 17 , wherein the vibration decoupling device comprises another vibration damper, the another vibration damper connecting the handle to the first mounting element.
