Definitions
- the invention relates to an expansion control for controlling the movements of the expansion units in the longwall of a mine.
- This control is e.g. B. known from DE 10207698.7 A1 (TBT 2104) and from DE 19982113.5-24 A1 (TBT 9805).
- the individual expansion units can, in this case
- Shields controlled from a central control or by individual control units, each of which is assigned to a shield (shield controls).
- Shield controls from each of the neighboring ones or several neighboring ones
- Shields can be controlled.
- the control signals are fed to all shield controls via a line common to all shield controls.
- the shield controls are programmed so that only the
- Shield control is addressed and the switching commands are executed, to which the code word sent with the control command is assigned. All other shield controls forward the control signal with code word.
- the object of the invention is an embodiment of the expansion control, in which faults in a shield control can be easily searched and in which, in the event of a fault, the system can continue to be operated.
- Figure 1 The section through a strut with an expansion
- Figure 2 The schematic plan view of a Schräm machine and a group of extensions.
- Figure 3 The schematic arrangement of central control and shield controls.
- FIG. 1 is one of the extensions. n pages 1-18 shown.
- FIG. 2 shows a plurality of expansion units 1 to 18. The expansion units are arranged along a seam 20.
- the seam 20 is mined in the mining direction 22 with a cutting device 23, 24 of a mining machine 21.
- the mining machine has the shape of a cutting machine 21.
- the cutting machine 21 can be moved in the cutting direction 19 by means of a cutting rope, which is not shown. It has two cutting rollers 23, 24, which are set at different heights and mill the coal wall.
- the broken coal is loaded onto a conveyor by the cutting machine, also called "Walzeniader".
- the conveyor consists of a trough 25, in which a tank conveyor is moved along the coal front.
- the cutting machine 21 can be moved along the Kohie front.
- the trough 25 is subdivided into individual units which are connected to one another, but can move relative to one another in the direction of degradation 22. Each of the units is connected by a cylinder-piston unit (walking piston) 29 as a force transmitter to one of the expansion units 1 to 18.
- Each of the expansion units serves the purpose of supporting the longwall.
- another cylinder-piston unit 30 is used, which braces a base plate with respect to a roof plate.
- the roof plate has a so-called coal bumper 48 at its front end facing the seam. This is a flap that can be folded in front of the dismantled coal wall. The coal bumper must be folded up in front of the approaching cutting machine 21.
- a further cylinder-piston unit, not shown, is also used for this.
- each of the power transmitters are hydraulic cylinders / piston units.
- a shield control 34 is assigned to each of the extensions 1-18.
- a face control 33 is assigned to a group of extensions or shield controls.
- One of the Schiid tenumaschinemaschine 34 is assigned to one of the extensions 1-18 and connected to the pilot valves 45 and main valves 44 of all power transmitters of the extension units 1, 2, 3 ... (to 18) via a valve controller 40 (microprocessor).
- Each of the shield controls serves as a central expansion control.
- a face control 33 or also the entirety of the shield controls, a central expansion control (main control center 50 and / or auxiliary control center 51), which is connected to the shield controls, can be assigned to a group of several shield controls.
- FIG. 2 Such an embodiment is shown in FIG. 2
- the central expansion control consists of the main control center 50 and the auxiliary control center 51.
- Cable 58 (bus line) connects all shield controls 34 to one another.
- the expansion commands are passed on via each shield control.
- the expansion command a certain expansion function z. B. in the sense of robbing, striding, setting triggered This expansion command is received and passed on by all shield controls 34 via the bus line 58.
- All of the expansion commands from one of the longwall controls are fed directly to the shield control connected directly to the longwall control 33.
- the removal commands then arrive from this shield control via the bus line 58 to all other shield controls 34.
- only one of the shield controls 1-10 or a group of shield controls is activated by a predetermined coding in order to carry out the respective expansion functions.
- the activated Shield control then converts the expansion command received into valve control commands to the control valves or main valves assigned to the expansions concerned.
- Control device 37 which is designed as a hand-held device and is carried by the operator, is used for central manual operation of the command input. To enter the command, the operator can stand outside the strut or at least away from the current dismantling location.
- the handheld device is connected via radio to the radio receivers 38 of the face control devices 33.
- the rectangular handheld device has control buttons on one side (control side). These keys can also be used to enter the code of the expansion control to be operated (one of the shield controls 34.1, 34.2 ...) and to trigger an expansion command to trigger a desired function or a desired functional sequence (e.g. robbing or walking).
- the antenna 39 of the handheld device is used for radio transmission.
- the control side of the handheld device is equipped with two diodes, a display and other buttons.
- the operator can light up the two diodes with his head lamp. Only if he covers one of the diodes, for example with a finger, will the control function of the handheld device be triggered.
- the operator enters the code of the removal to be checked.
- the hand-held device connects via an infrared transmitter / receiver 35 to a coordinated infrared transmitter / receiver 36 at the face control 33 addressed by code. Certain functions or operating states can now be queried using one of the buttons.
- a program is stored in the face control with which a sequence of queries about functions, operating states and functional sequences of a particular shoe (expansion) is addressed to the one addressed by code Shield control can be directed and carried out.
- the data obtained are then transmitted to the handheld device by means of the infrared transmitter / receiver 35, 36 and shown on the display. In this way, the operator can be convinced whether a certain configuration is still fully functional or whether maintenance or the replacement of functional elements or Controls are required.
- the shield controls 34 are connected to one another by the cable 58, which in previous versions has only two wires and which is used for serial transmission of a code word and the expansion command in each case. Only that shield control 34 / expansion unit is addressed, whose stored one The codeword is identical to the transmitted codeword
- the cable 58 is therefore a two-core cable which is laid in the form of a bus line from one shield control 34 to the next, and also the main control center 50 and the auxiliary control center 51 via the shield controls 34 in between connects with each other
- a second two-wire cable 59 is used in parallel, in this application as parallel Designated bus, laid In this application, cables 58, 59 are also referred to as bus lines.
- FIG. 3 Shown are two shield controls 34.1 and 34.2 from a variety of shield controls.
- the shield controls are connected to the main control center 50 and the auxiliary control center 51 via bus lines 58 and 59.
- the bus line 58 has the two chamfers 58.1 and 58.2; the bus line 59 has the two chamfers 59.1 and 59.2.
- All four phases of both bus lines are connected to the input elements 52 of the shield controls 34.1, 34.2, ... From the input elements, the incoming signals are processed in the shield controls d. H. first checked whether the code word sent corresponds to the code word stored and assigned to this respective label control. If the transmitted signals are control signals, the corresponding processing and transmission then takes place to the corresponding functional elements of the label, which have been described above.
- a chamfer 58.2 or 59.2 of each of the bus lines is then fed to a switching element 53.
- the corresponding chamfers leave the cutting element 53 via the output and are then fed to the corresponding switching element 53 of the adjacent shield control 34.2.
- both chamfers 58.2 and 59.2 can be separated synchronously or individually.
- the other chamfer 58.1 and 59.1 of the bus lines 58 and 59 are then fed to an amplifier element 54.
- the corresponding chamfers are fed from the output of the reinforcing element to the reinforcing element of the adjacent shield control 34.2.
- Each shield control 34.1, 34.2 ... then has a further “right” input element 52, which receives and processes the signals from the right side, ie the auxiliary center 51 or a shield control 34.3 .... further to the right.
- Adjacent shield controls 34.1, 34.2 are in turn connected by two cables, each of which has two chamfers.
- the switch 53 with its two switching elements is normally closed, so that a transmission takes place. However, the bus lines are disconnected when faults occur. On the one hand, this can make troubleshooting easier.
- the switching elements of the shield controls on the right or left are opened individually and in sequence by one of the control devices (main control center, auxiliary control center, hand-held device, face control or shield control) and then a control signal is input. Since the control signal is immediately acknowledged by the addressed shield controls, it can be determined which of the shield controls are beyond the faulty shield control. On the other hand, in the event of a fault, the separation can take place in order to isolate a faulty shield control and to separate it from the bus line or the bus lines. This means that the other shield controls can still be controlled and the troubleshooting can be carried out without the strut being shut down.
- Entetärkungsele ent 54 refreshes the incoming digital signals. This is done by determining in the amplification element whether the incoming signals exceed a certain predetermined threshold value. If this is the case, signals of greater strength, preferably of the original strength, are generated in the output so that the passage of the signals is ensured by all shield controls. This type of amplification is particularly useful because the control signals, signal signals, etc. are transmitted in digital form.
- control command is transported via the free bus line 58 or 59 in each case.
- the control commands are described in FIG Way through the individual shield controls 34.1, 34.2 .... passed through. Only the shield control is addressed whose stored code word matches the code word which is added to the control signal.Receiving and / or executing the corresponding control command can be acknowledged by a feedback signal, since one of the two bus lines 58 and 59 respectively The feedback can be given immediately and without a time delay, so that immediate control is also possible on the input device, ie main control center 50, auxiliary control center 51 or control device 37.
- the corresponding control signals are forwarded to the valve control 40 (FIG. 1).
- the control magnet of the pilot valve 45 is activated and the respective main valve 44 of the force transmitter 30 is actuated.
- the signals from the pressure sensors, which are arranged on each of the force transmitters and / or valves for control and monitoring, can now also be transmitted back via the bus lines.
- radio receiver 32 32. radio receiver 32
