Definitions

  • the invention relates to a grinding machine that can be manually moved on a track for grinding a rail of the track, with a support frame guided on the rails via two rail guides, on which a drive motor, which is coupled to a height-adjustable grinding element, is arranged.
  • Such a machine is, for example, from the DE 1 154 496 B known.
  • This is a rail grinding device that is supported on a frame and can be moved by hand on a rail by means of rollers, which is pivoted using a swivel bracket.
  • a grinding device is raised and lowered relative to the frame by means of a spindle drive.
  • the invention is based on the object of specifying an improvement over the prior art for a grinding machine of the type mentioned at the beginning.
  • the invention provides that the respective rail guide comprises a quick-change device in which one of at least two mutually interchangeable rail guide systems is attached. This allows the rail guide to be easily adapted to the local conditions on the construction site. In particular, the different guides enable ergonomic operation and flexible use of the grinding machine, depending on the work situation.
  • the respective quick-change device comprises a bushing with an internal toothing and that the respective rail guide system comprises a pin with an external toothing.
  • the positive connection of the quick-change device ensures safe guidance of the grinding machine.
  • the pin with external teeth is pushed into the socket with internal teeth and the respective rail guide system can be changed quickly and easily.
  • a further advantageous variant of the invention provides that the grinding element is connected to the drive motor via a transmission for power transmission.
  • the power transmission to the grinding element takes place in an optimized manner, with the drive motor and the grinding element being able to be arranged on different axes.
  • a further improvement of the device according to the invention provides that a resistance to a height adjustment of the grinding member can be adjusted by means of an adjusting element.
  • the height adjustment can thus be adapted to the respective requirement during work, in particular to compensate for wear on the grinding member.
  • the resistance of the height adjustment can be adjusted in a simple manner to the individual requirements of an operator.
  • a first rail guide system comprises only an inner cup washer and an outer cup washer for placing on a rail head.
  • the two cup washers are simply placed on the rail head at the desired angle to process it. This ensures quick and uncomplicated work progress.
  • an axis of rotation of the outer plate washer is inclined downward at an angle with respect to an axis of rotation of the inner plate washer. In this way, when side grinding from the rail, a higher holding or clamping force acts on the grinding machine. The grinding element is pulled more tightly to the rail head, which means that an operator has to apply less force.
  • a second rail guide system comprises two plate washers, a guide roller and a guide hook for placing on a rail head. This variant is particularly suitable for use in a switch area or at rail crossings.
  • the respective rail guide system is rotatably mounted on an axle driver.
  • the grinding machine is thus guided at the required angle to the rail and in the position desired by the operator.
  • axle driver is connected to a guide handle that can be rotated about a driver axis and mounted alternately.
  • the grinding machine can be easily adapted to individual ergonomic requirements and guided at the desired angle to the rails.
  • the alternating assembly of the guide handle means that the grinding machine can be used by both right-handed and left-handed people.
  • the guide handle can be locked using a locking device.
  • the guide handle which can be rotated together with the axle driver, is simply locked in the desired position.
  • the locking device is active, it is not possible to change the angle between the support frame and the guide handle, thus ensuring safe working.
  • the locking device is designed as a multi-disc brake.
  • Multi-disc brakes are subject to very little wear and tear and are almost maintenance-free, which means that they are not only very reliable, but also very durable and reliable.
  • the apparent grinding machine 1 for grinding rails 2 of a track 3 has a support frame 5 extending in the longitudinal direction 4 of the track, on which an axle driver 7 rotatably mounted about a driver axis 6, together with a rail guide 8 that can roll on the rails 2, is arranged at each end.
  • a bow-shaped guide handle 9 is arranged on the axle driver 7, with which the support frame 5 and a drive motor 10 arranged on the support frame 5 together with the grinding element 11 (grinding wheel, grindstone) can be pivoted about the driver axis 6.
  • a locking device 12 is provided between the support frame 5 and the guide handle 9, which is shown in FIG Fig. 1 is exemplified as a multi-disc brake.
  • the guide handle 9 can be rotated and locked in a desired angle to the support frame 5 by the operator.
  • a lamella brake that can be adjusted by means of a lever 13 is used as the locking device 12.
  • the guide handle 9, viewed in the longitudinal direction 4 of the track, can be mounted on both sides of the support frame 5.
  • the respective rail guide 8 comprises one of two different, alternatively usable rail guide systems 14, 15. During a grinding process, either a first rail guide system 14 or a second rail guide system 15 is installed. (in Fig. 1 both rail guide systems are shown for illustration).
  • the support frame 5 has two support rollers 17 that can roll on the rails 2 and a handle 18 at each end on.
  • the carrier rollers 17 (copier rollers) roll on the rail surface and form a surface reference for the grinding element 11.
  • the grinding element 11 is arranged to be variable in height via a height adjustment 19.
  • a spindle that can be rotated via a handwheel 34 and a corresponding counterpart serve as a height adjustment 19.
  • a rotational resistance on the handwheel 34 can be set by means of an adjusting element 20 acting on a disk spring assembly 21.
  • the adjusting element 20 is designed, for example, as a union nut with a non-slip surface.
  • the variable height adjustment 19 in combination with the exchangeable rail guide systems 14, 15 and the adjustable guide handle 9 enables a particularly efficient and ergonomic mode of operation and flexible use of the grinding machine 1.
  • the Figures 2 and 3 show two exploded views of the rail guides 8 with the two rail guide systems 14, 15.
  • the respective rail guide system 14, 15 is exchanged by means of a quick-change device 22 guided in the axle driver 7.
  • the quick-change device 22 comprises a rotatably mounted sliding bush 23 open on both sides with internal teeth.
  • a pin 24 with external teeth is pushed into this sliding bush 23 and locked.
  • the respective rail guide system 14, 15 comprises such a pin 24.
  • the first rail guide system 14 can be mounted on an inner end face of the slide bushing and the second rail guide system 15 can be mounted on an outer side of the slide bushing. Both rail guide systems can therefore be installed at the same time for transport or storage.
  • a fixation of the respective pin 24 takes place via a screw, but can also take place, for example, in a variant not shown, via a lever.
  • the first rail guide system 14 only comprises an inner cup washer 25 and an outer cup washer 26 for contact a rail head 27.
  • the outer plate washer 26 when the rail head 27 is grinded on the side has a larger diameter than the inner plate washer 25.
  • Each plate washer 25, 26 is rotatably mounted about a respective axis of rotation 28, 29, the axis of rotation 29 of the outer plate washer 26 being inclined downward at an angle ⁇ relative to the axis of rotation 28 of the inner plate washer 25.
  • the rail head 27 can be easily encompassed by means of the two cup washers 25, 26 in order to ensure reliable guidance of the grinding machine 1.
  • the inclination of the outer plate washer 26 by the angle ⁇ improves the holding force acting from the rail head 27 on the grinding machine 1, as a result of which an operator is relieved during side grinding.
  • the second rail guide system 15 comprises two plate washers 30, a guide roller 31 and a guide hook 32 for placing on the rail head 27.
  • the plate washers 30 are also rotatably mounted on axes arranged at an angle to one another.
  • the second rail guide system 15 can be placed in various positions on a rail 2 or on other elements of the track 3 (wheel guide, guide rail), which facilitates efficient processing of switches or rail crossings.
  • FIG. 7 shows various possible uses of the grinding machine 1 with the second rail guide system 15 installed.
  • the grinding machine 1 is supported upright on the rail head 27 on the support rollers 17.
  • the guide hook 32 and guide roller 31 of the second rail guide system 15 encompass the rail head 27. This position is particularly suitable for a head grinding of the rail 2.
