Definitions
- the invention relates to a method for adjusting an automatic level control of the planer in a hydraulic shield removal and with a planing on a trained planing leading thereto longwall mining Streb nowadaysen in underground coal mining, the Streb junker including the guided planer in its position in the mining direction on a can be changed on the shield extension supporting boom control and by means of the boom control a control angle for adjusting the movement of the planer in the direction of degradation as climbing, diving or neutral motion is adjustable.
- the equipped with chisels planer has an adjustment-related fixed cutting height and a relatively small depth of cut in the order of about 60mm, so that in contrast to a cutting extraction, the cutting height is certainly not variable during a planing pull along the face front.
- a level control of the planer is arranged on a between the longwall conveyor as a solid guide for the planer and the attached shield shielding arranged control cylinder as a so-called boom control.
- this Strebö réelle is defined by the distance between Hangendkappe and Bodenkufe of the respective shield frame in the region of the track.
- this Strebö réelle is defined by the distance between Hangendkappe and Bodenkufe of the respective shield frame in the region of the track.
- this method is in its statement fraught with uncertainties or requires corresponding delays in a possibly necessary regulation, because a reasonably safe statement about the cut from the plane material only after a few planks, ie after some, usually about five Passing by at a shield stand is to meet.
- the invention is therefore based on the object to provide a method of the type mentioned in which an automation of planing and finishing work in terms of producing a defined Strebö réelle and / or the leadership of the Streb joses on the prone horizon is possible in all operating conditions of the longwall ,
- the invention provides a method in which, for each planing pull, the depth of cut and the control angle detected as the difference angle between the inclination of the hanging end cap of the shield extension and the inclination of the longwall conveyor in the direction of dismantling are calculated and in a computer unit the resulting desired height change per planing pull is calculated in that in the computer unit each stripping train corresponding Streblage Strebageders a Streb doubt is assigned as a plan height, and wherein upon reaching the respective Streblage by a lagging behind the planter with a time delay Schildausbaugestell the shield construction, the actual height of the strut on the basis of is calculated by tilt sensors mounted on the shield support frame and compared with the stored plan height, and wherein a height difference value between plan height and actual height determined for the respective strut layer is in the sense of a self temper cement
- the procedure according to the invention initially assumes that, depending on the depth of cut of the planer with each planing pull, a change in the height of the reach results over the unchanged or consistently assumed hanging wall horizon fixed by the hanging wall end cap of each shield support frame.
- a setting of the planer via the control angle thus leads to an increase in the height of the strut, and a climbing of the planer leads to a reduction in the height of the strut.
- the plan height is not reached in practice, but rather results in a lower actual height of the strut, the present invention Reaching the respective Streblage is determined by the lagging behind the planer with a time delay.
- the actual height is calculated on the basis of values taken by tilt sensors attached to the shield frame; However, the detection of the required values and the calculation method itself are not the subject of this invention.
- the height difference value to be compensated for compliance with the desired height of the strut between the plan height and the actual height in the adjustment of the control angle is already taken into account, for example, to achieve a certain height change in terms of compliance with the target height of the strut is set larger or smaller by a control cycle consisting of a plurality of plow trains by an angle amount corresponding to the ascertained height difference value, so that the actual height of the strut reached in each case corresponds to the desired height dimension.
- the time delay necessarily given by the checking of the actual height of the strut on the longwall delay track following the planer with a time delay can be shortened so that a correspondingly large control loop is established.
- the inclination of the longwall conveyor is namely to detect immediately after each control process with respect to the control angle and can already be used as a first correction value for the level control.
- the respective control angle given by the computer unit is set in relation to the height difference value resulting from the planing pull, and the limit control angle of a reflection area determined within the self-learning effect is stored in the computer unit, within each case Applicable, even different control angle produce no changes in height in the strut height, so that the influence of a greater strength than the carbon strength having recumbents is taken into account in the sense of boundary layer detection or a boundary layer-guided Hobeins. If despite a control angle set to dive on the boom control by the plow trains no change in the reach height occurs, it is clear that the planer moves in prone contact, the hard lying but prevents penetration of the planer with a dipping motion.
- the computer unit can identify the reflection area as a controller.
- a climbing movement or a submerged movement of the plane is necessary when setting one to achieve a desired height of the strut effecting control angle takes into account the size of the respective valid reflection range and the control angle is set to bring about the climbing or dipping movement with a lying outside the reflection range value.
- a characteristic map for the ratio of control angle and height difference value that is matched to the set bottom tool position and learned via the previous offset is called up relative to one another. If such a map is not stored in the computer unit, the controller must first develop a map adapted to the new bottom tool position during the subsequent planing trains.
- an automatic passage of saddles and troughs is possible by determining the course of troughs and / or saddles in the degradation direction according to an embodiment of the invention on the determination of the slope of the hanging wall of the shield extension in the direction of degradation and in the computer unit an adaptation of Sectional track of the planer is set parallel to Hangendverlauf and a the radius corresponding to the trough or saddle curve corresponding additional height containing adjusted desired height of the strut is made by adjusting the control angle of the planing level control. If the controller detects a decrease in the radius of the trough or saddle curvature, the additional height calculated is withdrawn again.
- the continuous detection of changes in the height of the shield extension point indicates the convergence that has occurred in each case, as far as a loss of height is determined on the shield support frame during planing work, ie when the shield extension is stopped.
- the height of the shield extension determined by both continuous planing to planing pull and at standstill of the strut the respective incoming convergence and continuously taken into account by adjusting the height difference value to be used for setting the control angle of planing level control becomes.
- An occurred loss of height must be achieved by increasing the control angle to achieve or maintain the desired target height and thus by a Magnification of the plan or actual height set by the planing work can be compensated again.
- the longwall opening can be selectively increased by increasing the control angle and thus increasing the height difference value so that despite a convergence occurring at the weekend at the beginning of the week, the desired height of the strut for restarting the strut is available.
- an embodiment of the invention provides that when a occurred during a standstill of the strut sole elevation detects the change in the inclination of the longwall conveyor at standstill of the planer and recalculated before the planing work required to achieve the desired height of the strut control angle.
- a plurality of shield extension points and associated boom cylinders of the boom control are combined to form a group-controllable group.
- each shield support frame has a different device tolerance in the establishment of tilt sensors attached to it, a fully parallel mechanical alignment of the inclination sensors is not possible for shield mounting rack.
- a fully parallel mechanical alignment of the inclination sensors is not possible for shield mounting rack.
- the individual Shield Rack Failure to detect the control angle as the difference between the slope of the hanging wall and the slope of the longwall conveyor.
- control technically connected groups of shielding outstations applicable to the adjacent groups control angle are balanced such that to avoid mechanical overuse of the compounds preset maximum differences between the control angles which apply to the adjacent groups are not exceeded by the part-channel shots of the longwall conveyor assigned to the groups.
- a group of means of Group control is associated with each associated shield extension points a central, mounted on the longwall inclinometer inclination sensor;
- a plurality of inclination sensors arranged on individual conveyor troughs of the longwall conveyor are arranged within a group of tiling stations coupled to one another by means of a structural control.
- a tilt sensor mounted on the longwall conveyor may be sufficient.
- a tilt sensor unit attached to the longwall conveyor is designed as a twin sensor having two tilt sensors of the same type. This has the advantage that both sensors mutually check the display accuracy within a plausibility field and in case of deviations above a tolerance band can give an error message regarding the display accuracy, whereby a sensor drift can be detected. Another advantage is that in case of failure of a sensor, the second sensor can maintain the function and generate the system of a fault message.
- an attached to the face conveyor tilt sensor unit consists of two similar, with a counter-rotation direction about the measuring axis mounted sensors.
- the opposite in the direction of rotation about the measuring axis sensor arrangement of two similar sensors in differential circuit can be used to compensate for vibration (rotatory) errors of the sensors and significantly attenuate the measured value display, without losing accuracy.
- the average actual angle of the longwall conveyor to vibrate the longwall conveyor can be largely displayed torsional vibration adjusted, since both sensors oscillate with the same frequency and amplitude and is compensated for opposite evaluation in the interference method of the signal superimposed by the oscillation signal component, so that the display angle as much remains at system quiet.
- the hydraulic boom cylinders of the boom control which are supported between the shield extension points and the longwall conveyor, to be hydraulically releasable by means of the piston surface and the annular surface of the latter
- Check valves are hydraulically lockable after reaching their control position, the check valves are connected by means of associated control lines with the associated group control.

- Fig. 5 to be set in an automatic level control
- the longwall equipment shown schematically in Figure 1 initially has a shield support frame 10 with a hanging end cap 1 1 and a bottom skid 12; between Bodenkufe 12 and Hangendkappe 1 1 two stamps 13 are attached in a parallel arrangement, of which in Figure 1, only one stamp is recognizable.
- a fracture shield 14 articulated, the structure of such a shield support frame 10 is known, so that it will not be further explained , At least on his hanging end cap 1 1, a tilt sensor 15 is attached; As not further illustrated, 10 more inclination sensors are mounted on the Bodenkufe 12 and on the fracture shield 14 and / or on the fracture shield 14 supporting support arms to the shield support frame. With the aid of the measured values recorded by the tilt sensors, the height of the shield support frame between the hanging end cap 1 1 and the bottom skid 12 can be calculated.
- a longwall conveyor 16 is struck, which has a planing guide 18 with a planer 17 guided thereon on its (non-illustrated) dismantling side (not shown).
- the longwall conveyor 16 with the planer guided thereon 17 is arranged pivotably by means of a boom cylinder 19 relative to the shield support frame 10.
- the Streb couponer 16 with planer 17 is pivoted in the direction of a dipping motion, with a set via the boom cylinder 19 control angle 20, which is a differential angle between the position of the hanging wall 1 1 of the shield support frame 10 and the inclination of the longwall conveyor 16 in the degradation direction.
- the respective inclination of the longwall conveyor 16 can be detected or detected in the direction of dismantling via a tilt sensor 15 attached to the longwall conveyor 16.
- FIG. 1a With the illustration of 17 plow trains in the context of a control cycle, with each plow train a presumed constant cutting depth 21 is achieved, namely for each uphill journey 22 and for each downhill journey 23. Due to an embodiment shown in FIG. For example, set to dive, decreasing predetermined in the second half of the control cycle control angle is determined in the associated computer unit for each planing train 22, 23, the expected plan height of the strut or achievable per planing plan height difference determined on the 17 planer trains of the in Figure I a control cycle is plotted as a curve 24. The respective review of the actually achieved height of the strut leads to a curve, as it is plotted as a curve 25.
- the amount of height difference is designated, which must be cut in order to achieve the desired desired height of the strut.
- the amount 27 corresponds to the actually freely cut height difference in the actual height of the strut, so that a height difference value 28 can be determined as the difference between the amounts 26 and 27 or can be determined by the computer unit.
- the control angle 20 is to be set for the individual ascents and descents 22, 23 of the planer, the control angle must be adjusted by the height difference value 28 by taking into account the height loss between plan height and actual height so that ultimately the actual Height increase 27 corresponds to the required height increase 26.
- the plan height curve 24 resulting from the control angle is to be set so that the actual height curve 25 ends at the amount of the required height difference.
- the controller or the computer unit is able to learn the actual implementation of the plan height in the actual height and to use for the calculation of the control strategy for the following planing trains.
- an excavation progress of, for example, 20 m has to be passed through with manual planing level control, in which the control system learns passively the control behavior for the relevant longwall.
- the automatic planing level control can be put into operation, which further learns the control behavior in the course of the further mining step and continuously optimizes the control strategy.
- control angle 20 in a Strebièrendifferenz for setting or maintaining a desired height of the strut is dependent on the secondary rock conditions, especially in the footwall, because the hanging wall should remain as unscreened as it forms the leadership horizon for the shield extension. If the lying is softer than the coal to be recovered, it is very difficult to maintain a desired longwall height, because the planer without control horizon, so-called “floating" must be controlled in the range of the target height.This requires frequent control interventions, as the Due to the process, this unstable equilibrium in the control requires a large range of variation in the head height, which entails the risks of mountain rescue, coal mining and leaving the adjustment range of the expansion ,
- the horizon can be included as a management level for the planing work, in the sense of a Grenz Mrshobeins.
- a hard lying means that, despite a control angle set to dive, the planer initially does not cut into the recumbent and thus does not set any actual height change, despite the plan height per planing pull resulting from the adjustment of the control angle.
- the lying reflects, so to speak, the Control movements of the planer, which is why the addressed area for the control angle can also be referred to as a reflection area.
- This reflection range with respect to the set control angle extends from a lower limit, which marks the boundary line for climbing the planter, to an upper limit, when exceeded due to the set control angle, the planter overcomes the resistance of the horizontal, cuts into the lying and thus performing an effective dipping motion.
- a lower limit which marks the boundary line for climbing the planter
- an upper limit when exceeded due to the set control angle, the planter overcomes the resistance of the horizontal, cuts into the lying and thus performing an effective dipping motion.
- the effective control angle achieved with regard to the actual height of each planing draft deviates from the set control angle, as shown in FIG. 2, left half.
- the reflection range almost completely disappears despite a control angle set in the reflection range, because control angles set in the reflection range do not cause an actual height difference here.
- the relevant conditions are also recognizable from FIG. 2a with the control characteristic 33 reproduced therein.
- a control angle set between + 3gon and - 3 gon a change in the effective control angle does not take place;
- the control strategy assumes that the control angle is set in the middle of the reflection range upon detection of a reflection range during planing work by the controller or the computer unit in order to have enough flexibility in the implementation of the set control angle in the machine technology, without that the reflection area is left and the planer effectively performs unwanted tilting movements.
- the boom cylinder 35 are each provided with a Einzelabsperrung, so that the boom cylinders 35 are hydraulically lockable after reaching their control position. As can be seen from FIG. 4b, the boom cylinders 35 remain unaffected by the plow passage.
- a control sequence following the planer can be activated, in which the extension of the shield after the planing passage is first moved according to plan.
- the individual control groups of the shield removal point sequentially receive the control order sequentially to set the control angle for the next planing pass and subsequently to carry out no readjustment. This tolerates the possible influence of a control group by the subsequent control group. Occurring deviations in the control angle are included by the computer unit in the future control strategy, the control angle but adjusted after the next planing pass. Due to such a strategy, the control shaft passes through the strut following the planer. An unstable control by feedback effects of adjacent control groups on each other are safely avoided.
