Definitions

• the invention relates to a manually displaceable on a track
• Working module comprises a pivotable grinding unit.
• the invention is based on the object of specifying an improvement over the prior art for a grinding machine of the type mentioned in the introduction.
• the invention provides that the grinding unit comprises an electric motor and a grinding unit driven therewith, that the grinding unit is mounted pivotably about a longitudinal axis in a motor frame and that the motor frame is arranged adjustable relative to the supporting frame. Due to this compact design and the flexible adjustability of movably mounted elements, almost any point of the rail profile can be machined with high accuracy and efficiency.
• the grinding unit is at least 180 ° relative to the motor frame
• both sides of the rail profile can advantageously be processed in a plurality of working positions with a grinding unit.
• a further improvement of the device according to the invention provides that the grinding machine comprises a heat exchanger and a pump and that the electric motor is designed with a liquid cooling.
• Grinding machine comprises a compressor and when the electric motor is designed with a compressed air cooling.
• the electric motor can be designed in a compact design and the cooling system is virtually maintenance-free.
• a simple embodiment of the invention provides that the electric motor is connected via sliding contacts with the power module.
• Sliding contacts ensure flexible energy transfer to the electric motor.
• a further advantageous embodiment of the invention is given by the fact that the electric motor is connected via a flexible cable and a plug connection with the power module. This flexible connection ensures a generous freedom of movement of the electric motor during work. The power module can be easily decoupled from the electric motor for transport via the plug connection.
• a further improvement of the invention provides that the motor frame is mounted vertically adjustable in an intermediate frame and that the
• the motor frame for angular release of the grinding tool relative to the intermediate frame is arranged pivotable about a vertical axis.
• the grinding tool is placed on the rail surface at a predetermined angle and the rail is precisely machined.
• the intermediate frame is mounted by means of manually releasable roller elements on the support frame. This will be the
• an internal combustion engine / generator unit is arranged as the energy module.
• the energy module comprises a
• electrical energy storage For this purpose, electrical energy is temporarily stored for a longer working use of the grinding machine. With sufficient sizing of the accumulator, a servicing internal combustion engine / generator unit can be switched off in the meantime (for example in tunnels) or eliminated altogether.
• a simple embodiment of the invention provides that the support frame is designed to be split with an adjustable distance between the guide rollers associated with one rail and the guide rollers associated with the other rail. This makes it possible to adapt the grinding machine to any gauge of the track.
• the energy module with the support frame by means of manually detachable Fastening elements is connected.
• the transport of the energy module separate from the support frame is thereby considerably facilitated.

• Angle-release device 24 For this purpose, the motor frame 9 together with the grinding unit 10 is mounted pivotably on a vertical axis 25 in the intermediate frame 8 by an offset angle cc. About two handles 26, the required pivoting range and thus the grinding unit 10 is set relative to the rail 2 and locked by clamping lever 27.
• FIG. 3 shows a detailed view of the motor frame 9 together with the grinding unit 10.
• the grinding unit 10 includes an electric motor 28 and a grinding tool 29.
• the grinding tool 29 is shown as a disk grinding wheel and is replaced depending on the application by other grinding tools.
• the grinding tool 29 is directly on a rotor shaft of the
• Electric motor 28 connected, creating a particularly compact
• Construction of the grinding unit 10 is given. In this way, it is possible to pivot the grinding unit 10 by at least 180 ° about the longitudinal axis 23 and thus ensure the flexible applications.
