Definitions
- the invention relates to a device for coal mining according to the preamble of
- a number of Funkempfä ⁇ gem are mounted in the longwall, which are serially coupled to a central office in the head section (Streb grisgerat).
- Each addressed radio receiver receives continuously the information of the
- Planing machine is still driving in the area of the coal impact or already the
- Boundary layers of the rock breaks. Depending on this, the planer must be raised or lowered.
- the raising of the planing machine (climbing) is done by lowering the gutter edge, the planing machine tilts around a arranged in the middle of the width of the trough sliding foot.
- the lowering of the planer (diving) happens in that the
- Expansion devices adjacent gutter edge raised by a tilting device and thereby the planing machine is pivoted about the Gieitfuss in the opposite direction.
- the solution according to claim 1 is based on the finding that the
- Control of the planer is sufficient. In the area of each expansion unit, preferably only two measurements are carried out at substantially the same height.
- the embodiment of claim 3 is characterized in that the processing can be done in any shield control device, but in particular in the shield control device, which is in each case a tilting device closest and is therefore assigned.
- each shield control device is equipped with its own computer and control capacity, so that it can be determined by means of a preferably stored in each shield control program, whether the planer currently breaks in the last run over expansion units predominantly rock or coal.
- a pre-evaluation of the measured rock signals takes place in a microprocessor carried by the planing machine.
- This pre-evaluation may go so far that only simple "black and white” signals "coal or rocks" need to be transmitted by the radio associated with the rock sensor, in order to enable the controller to determine the length of the detected rock the position of the planer to be changed, the device is equipped according to claim 5 with inclinometers (inclinometer).
- This Inkiinometer can be connected to transmit all Meßsignaie via a laid along the conveyor bus line with the longwall control device.
- the embodiment according to claim 6 is used.
- the radio receiver for the tilt signals are assigned directly to that shield control device, which is the inclinometer closest. This is usually the shield control device, which is associated with the tilting device locally and functionally in the embodiment according to claims 1 to 3.
- the embodiment according to claim 9 ensures a long life and Ladu ⁇ gsdauer the battery.
- claim 9 makes use of the fact that the measuring and transmitting function of the in-limiter is required only for a very short time (for example 5 to 10 seconds) during the time of passing the planing machine at the specific number of expansion units, which are assigned to the Inkiinometer to the rock data to eg to transmit two measuring points per expansion unit. For this reason, activation of the battery supply of the in-limiter and the transmitter mounted on the in-line meter is effected by the passing planer, e.g. by a coded in a special way radio signal of the planer or a sensor of the planer. The shutdown of the battery supply can then be done after a preset period of time.
- Fig.1 is shown as an embodiment schematically the view on or in a longwall
- Fig. 2 shows a detail of a Inkiinometer.
- Planing machine 2 is pulled by conveyor chain 23 along the coal shot (not shown) at high speed (eg 3m / s) through the strut (of eg 300m length).
- the planing machine is guided on the channel consisting of sections 4 channel 18.
- the broken coal is conveyed to one of the longwall ends.
- the longwall is covered and supported upwards by a series of expansion units (shields), which are placed on the Togewa ⁇ dten from the coal side of the channel close together and next to their function of supporting the mountains also have the function to support the channel in the direction of the coal shot and the gutter sections to follow up the mining of the coal impact.
- each expansion unit has a tilting device 5, which will be described below.
- Each expansion unit further has a shield control device, construction control unit 12 for controlling the functions to be performed by the individual expansion units, in particular pulling (robbing), advancing (stepping) and positioning and bracing (setting).
- the expansion units of a longwall are connected to each other by a bus line through which commands, measurement signals and function signals can be passed to each of the shield control devices and finally via connection line 21 also to the long-distance control device and / or the central control unit.
- the planing machine 2 is equipped with a rock sensor 3 and associated microprocessor 28.
- rock sensors are known and are supplied, for example, by the company TEC5-AG in Oberursel. Their task is to continuously analyze the rock or coal appearing in the cutting area of the planing machine in the excavation area of the passing seam and to recognize whether the planer's planing machines attack in the area of the seam (coal) or leave the seam upwards or downwards ( Rock).
- a strut of 30Q m length in a back and forth direction is traversed in little more than 3 min, and
- corrections are made on the basis of the evaluation and, in particular, the mean value of the measured values which occur between two (or also several corrections of the planing position.
- the rock sensor is also equipped with the illustrated microprocessor 28, the carries the planing machine.
- the illustrated microprocessor By this microprocessor, a first evaluation of the data of the rock sensor is carried out in the sense that the output signal transmitted by the rock sensor via radio 9 is already understood and used without further time-consuming evaluation and at best already the unique Errformation: "rock” or " Coal "includes.
- radio transmitter 9 which transfers the rock data -eventually after and in the form of the evaluation described by the microprocessor 28- to one of the radio receiver 11, of which each one each of the layout controllers in each of the expansion units is assigned.
- the radio traffic is thus limited to relatively small and unambiguous amounts of data and to the near range of no more than 3m, since there is only a short gap between the transmitter 9 and one of the receivers 11.
- the transmitted data are then forwarded by the receiving installation control via the bus line 22 to the long-distance control device and the central control unit.
- the position of the channel or portions of the channel is given to the long-distance control device and the central control unit.
- several inclinometers 20 are attached to the gutter, each one of which is assigned to a group of adjacent gutter sections. If not every removal unit is associated with a tilting device but only every 6th removal unit, for example, an inkerometer is also disposed on the channel in the area of the attack of the respective tilting device or on the runner section on which the tilting device engages.
- An inclinometer thus comprises a group of gutter sections. Such a group comprises in the illustrated case 5 or 6 adjacent sections.
- Each inclinometer 20 is provided with a Radio transmitter 24 provided.
- the inclination of the channel is given to a radio receiver 25, which is respectively connected to the construction control unit 17 of that expansion unit, which is the inclinometer 20 closest to the other.
- radio receiver 25 There are special radio receiver 25 drawn here;
- the inclination data can also be received by the already described radio receivers 11, if the rock data and the inclination data are transmitted in a coded coded manner, so that it can be decided in the receiving component control whether it is rock data or inclination data received receiving control unit 12 via the bus line 22 and 21 connection to long-distance control device and the central control unit.
- Positionsmeider each of which is assigned to each expansion unit, each determines the presence of the planer and reports on the associated ECU to the longwall control device and the central control unit.
- Other types of position detection are conceivable, cf. eg DE 19982 113.5-24
- each inclinometer has a sensor 27 (e.g., transponder) which detects the presence of the planing machine and turns on the power supply depending on the approach of the planer and turns it off when the planing machine is removed. In this way, it is possible to perform without the disturbing in Sergbau supply lines to the inclinometers and trouble-free Wess concede in the relevant phases of the planing.
- a sensor 27 e.g., transponder
- Fig.2 enlarged one of the inclinometer 20 is shown.
- Each of the inclinometers may be powered by a battery / accumulator 26 or the like.
- the inclinometer has a sensor 27, eg transponder, light emitter / receiver or the like, which closes the switch for power supply of the radio transmitter 24 of the inclinometer with adjustable approach of the planing machine and reopens after passing by - depending on the distance or eg time-dependent , This allows the energy consumption so be reduced that the inclinometer can be operated not only without supply but also for a long time maintenance-free.
