Definitions
- the invention relates to a sensor device for signaling wear states on grinding wheels according to the preamble of claim 1.
- the current collectors of electrically operated vehicles generally consist of grinding wheels which are attached to a metallic carrier, which in turn is connected to a pantograph which presses the grinding wheel against a current-carrying conductor of an overhead line system.
- the grinding wheels are subject to high friction stress, particularly at high speeds.
- vibrations and shock loads occur.
- the purpose of sensor devices for signaling wear conditions on grinding wheels is to signal malfunctions and wear conditions to the operating personnel as part of the monitoring and security system. Such devices are known in various designs.
- DE 44 254 60 AI describes an operational monitoring arrangement for contact strips of pantographs.
- the arrangement is particularly characterized in that the grinding body has a groove on the carrier side in which fluid pressure is maintained. If the grinding wheel is damaged, which leads to a pressure drop in the groove, the pantograph is immediately lowered and the electric vehicle may stop.
- This system is designed in such a way that the vehicle may stop in the event of a drop in pressure and thus disadvantageously a problem can arise in returning or repairing the vehicle. Preliminary stages of this total failure by determining the beginning of wear and tear cannot be accomplished using this monitoring system.
- EP 0 525 595 AI describes a monitoring device for pantograph contact strips, in which several light guides are embedded in the pantograph contact strip.
- the ends of the light guides embedded in the contact strip are connected to the transmitter and receiver, which send and receive light pulses through the light guides. If a light guide were damaged, the predetermined sequence of light pulses would be disturbed and a fault would be signaled.
- the introduction of the light guides into the contact strip, as described here requires relatively complicated technological processes in order to guide these ' light guides lengthwise through the contact strips. There is also a mechanical weakening of the contact strips due to the embedded light guide.
- the invention is based on the object of specifying a sensor device which, at practically any location on the contact strip, can be used to install signal transmitters which can signal the respective state of wear of the contact strip without interrupting driving operation.
- the problem is solved with the features of claim 1.
- the sensor device for signaling wear conditions on grinding bodies of current collectors of electrically powered vehicles is characterized in that the sensor device consists of blind holes made in the grinding wheels, of transmission channels connected to the blind holes and of a monitoring unit, blind holes and monitoring unit being connected via the transmission channels are, and that in the blind holes is a medium generating signals with a certain state of wear and in the transmission channel is a medium transmitting these signals to the monitoring unit.
- the signal-generating and transmitting medium is identical.
- the signal-generating and transmitting medium is advantageously a pressure fluid.
- Compressed air is particularly suitable for this.
- the signal-generating and transmitting medium is an electrically conductive medium.
- the signal-generating and transmitting medium is a light-guiding medium.
- the signal-generating medium and the signal-transmitting medium are not identical, as is the case, for example, in the conversion and transmission of light signals in or as electrical impulses.
- the signal-generating medium is a current conductor, an optical fiber, a photodiode or a camera.
- a plurality of spaced blind holes are provided in a further embodiment, so that the state of wear can be determined as far as possible over the entire grinding wheel.
- the arrangement of the spaced blind holes is carried out vertically in a further embodiment.
- Another important advantage of the invention is the possibility of providing the blind holes with different hole depths, so that the wear state of the grinding wheels can be assessed by the operating personnel at any time.
- each blind hole or groups of blind holes have separate transmission channels.
- the embodiment of the invention to guide the blind holes in the grinding body through a side surface at an acute angle in the direction of the grinding surface offers the advantage of also subsequently providing the grinding strips with sensor devices in a particularly effective manner.
- the invention provides a cylindrical or a conical shape of the blind holes.
- the cone shape offers the advantage that, in conjunction with the use of photodiodes or a camera, the size of the incident light cross section is continuously recorded and thus a measure of the comparative state of the monitoring unit is transmitted.
- the signal generating Medium such as a photodiode or a camera, can be arranged in the area of the hole entrance of the blind hole.
- a pressure fluid such as, for example, is additionally provided in the blind holes and the associated transmission channels. Compressed air, so that if the blind holes are exposed, e.g. a conical blind hole, through which normal wear penetrating material is blown out and the function of the photodiode, the camera or the light guide is not impaired.
- the transmission channels are arranged below the contact material in the carrier and from there are connected to the monitoring unit with further transmission channels.
- a further embodiment provides that the transmission channels connected to the blind holes are arranged outside the carrier and from there are connected to the monitoring unit with further transmission channels.
- different warning signals with different wear conditions of the contact material can be displayed using separate, differently set monitoring devices.
- the displayed wear conditions of the contact material depend on the depths of the outflow nozzles in the contact material.
- several warning levels can also be implemented with several discharge nozzles of different lengths and diameters. be lized. Less medium flows out through the outflow nozzle of smaller diameter. The flow rate is therefore less than with a larger diameter discharge nozzle.
- the monitoring device assigns the corresponding flow to the corresponding output signal.
- FIG. 1 is a schematic side view of a contact strip fixed to a carrier with transmission channels in the carrier
- FIG. 2 is a sectional view of an approach of the further transmission channel (section B-B of FIG. 1)
- FIG. 3 is a sectional view of a blind hole in the grinding wheel (section A-A of FIG. 1)
- FIG. 4 shows a sectional illustration of a grinding wheel with a transmission channel arranged outside the carrier
- FIG. 5 shows a further sectional illustration of a blind hole (section C-C of FIG. 4),
- 6a is a schematic side view of blind holes made at different heights
- 6b shows the horizontal distribution of the blind holes made at different heights
- 7 is a sectional view of a blind hole in the shape of a cone
- Fig. 9 is a schematic sectional view of the blind holes with current conductor, photodiode and light guide
- Fig. 10 is a schematic side sectional view of the blind holes with a conical shape and arranged photodiode and light guide.
- FIG. 1 shows a contact strip fixed to a carrier with transmission channels in the carrier as part of a current collector 1.
- FIGS. 3 and 2 The associated cuts AA and BB are shown in FIGS. 3 and 2.
- a grinding body 2 is fixed with its base surface 22 to a profile surface 71 of a carrier 7.
- a grinding surface 21 of the grinding body 2 contacts the overhead line, not shown here.
- Carrier channels 72 are introduced into the carrier 7 below the profile surface 71 of the carrier 7.
- the carrier channels 72 extend essentially over the entire length of the carrier 7.
- Blind holes 3 are made in the grinding body 2 in such a way that they have a direct connection to the carrier channel 72 with a hole entrance 33.
- the blind holes 3 can be introduced into the grinding body 2 in such a way that, after the grinding body 2 has been fixed on the profile surface 71 of the carrier 7, a bore is made through the carrier 7 and carrier channel 72 into the grinding body 2.
- 2 shows the arrangement of a screw-in element 61 in the carrier channel 72.
- the screw-in element 61 is provided with a hose connection 62 to which a transmission channel 6 can be connected.
- two carrier channels 72 are provided in the carrier 7.
- the provision of further carrier channels 72 is possible and depends on the arrangement and number of blind holes 3.
- a hole depth 32 which extends from the hole entrance 33 to the hole base 31, determines a wear level 23.
- the transmission channel 6 is continued into the monitoring unit, not shown here.
- Compressed air is provided as the signal generating and transmitting medium, which is introduced into the system consisting of transmission channels 6, carrier channels 72 and blind holes 3.
- the wear level 23 is reduced by removing the contact material.
- the compressed air escapes, so that a significant pressure drop or a significant change in the flow resistance of the compressed air occurs, which is processed and displayed as a wear signal in the monitoring unit.
- an air / gas mixture continuously flows through the opened discharge nozzle during use.
- the flow rate can be changed.
- FIGS. 4 and 5 show a modified variant of the transmission channel and the blind hole 3.
- a screw-in tube 34 is inserted into the blind hole 3, which is introduced into the grinding body 2 as described above.
- a rotatable angular displacement attached outside the carrier 7 screw 35 enables the connection of transmission channels 6 designed as hoses.
- blind holes 3 of different heights are made in the grinding wheel 2.
- the blind holes 3 are shown with a hole depth 32 A, B and C, where A means the smallest hole depth and C the greatest hole depth.
- 6b with a view of a grinding surface 21, a distribution of the blind holes 3 over the width of the grinding body 2 can be seen.
- the different hole depth 32 of the blind holes 3 advantageously enables wear conditions to be documented at an early point in time.
- Fig. 7 shows a blind hole according to the invention in the shape of a cone.
- the cone shape has the advantage that when using light-measuring signal-generating media such as a light guide 5, a photodiode 8 or a camera 9 a progress of the wear can be continuously recorded over time.
- the outflow quantity of the fluid increases with increasing wear of the grinding wheel, which, with a suitable evaluation, indicates the respective actual state of the useful strength of the grinding wheel.
- FIG. 9 shows an example of the arrangement of the current conductor 4, the light conductor 5 and the photodiode 8 or the camera 9. If the abrasion of the grinding wheel 2 reaches the hole base 31 of the blind hole 3, the corresponding signals would be transmitted to the monitoring unit here by the incidence of light or by the resulting current flow in the case of the current conductor 4.
