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.
Claims18
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.
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.
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:
