[Technical field]

[0001] The present invention relates to a moving device for a coke oven. [Background technology]

[0002] Coke ovens equipped with moving devices such as guide cars and pushers are known. For example, Patent Document 1 describes a coke production facility equipped with a coke pusher, a charging car, a coke guide car, and a bucket car. The coke pusher pushes out the carbonized coke with an extrusion ram. The charging car throws coal into the carbonization chamber from above. The coke guide car introduces the pushed out coke into a bucket. The bucket car receives the coke in the bucket and travels on a rail. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2012-166925 A Summary of the Invention [Problem to be solved by the invention]

[0004] The mobile equipment receives power from an external source via a trolley and operates on that power. Therefore, if the external power becomes unavailable due to a power outage or other reason, the mobile equipment will stop in the state it was in when the power outage occurred. Since temperatures inside a coke oven reach over 1000 degrees, if a power outage occurs while the mobile equipment is loading coal or pushing out coke, the mobile equipment will be exposed to the high temperatures inside the oven for a long period of time and may break down.

[0005] This problem is not limited to extruders, but may also occur with other types of moving equipment performing certain functions in coke ovens.

[0006] The present invention has been made in consideration of the above problems, and one of its objects is to provide a moving device for a coke oven that can avoid breakdowns in the event of a power outage. [Means for solving the problem]

[0007] In order to solve the above problems, a coke oven moving device according to one embodiment of the present invention is a coke oven moving device having a moving part that moves based on the output of an electric motor driven by an external power source, the moving part including a battery that is repeatedly chargeable and dischargeable and is charged by the external power source, and a control unit that controls the electric motor. When a power outage occurs, the control unit supplies the electric power of the battery to the electric motor and controls the electric motor to move the moving part in the evacuation direction.

[0008] Any combination of the above components, or mutual substitution of the components or expressions of the present invention between methods, systems, etc. are also valid aspects of the present invention. Effect of the Invention

[0009] According to the present invention, it is possible to provide a moving device for a coke oven that can avoid breakdowns in the event of a power outage. [Brief description of the drawings]

[0020] The guide car 60 is arranged on the rails 61 so as to be movable in the Z-axis direction on the discharge port 43 side of the carbonization chamber 41. The guide car 60 includes a hood 62 for guiding the extruded coke 90, and a second moving device 310. The guide car 60 guides the extruded coke 90 with the hood 62 and sends it to the bucket car 72 of the bucket car 70. The hood 62 moves in the Z-axis direction in synchronization with the bucket car 70 while covering the upper part of the bucket car 72, and guides the dust-containing gas generated from the coke 90 to a dust removal treatment facility (not shown). The second moving device 310 includes a traveling motor. The guide car 60 has wheels 60w, and can move under its own power by rotating the wheels 60w with the traveling motor. The second moving device 310 will be described later.

[0021] The bucket car 70 is arranged on the rails 71 so as to be movable in the Z-axis direction on the discharge port 43 side of the carbonization chamber 41. The bucket car 70 includes a bucket carriage 72, a towing vehicle 73 for towing the bucket carriage 72, and a third moving device 410. The bucket carriage 72 is configured to be capable of loading coke discharged from the hood 62 of the guide vehicle 60. The bucket carriage 72 can load coke 90 and move on the rails 71 by being towed by the towing vehicle 73. The bucket car 70 transports the loaded coke 90 to a fire extinguishing facility (not shown). The third moving device 410 includes a traveling motor. The towing vehicle 73 has wheels 73w, and can move under its own power while towing the bucket carriage 72 by rotating the wheels 73w by the traveling motor. The third moving device 410 will be described later.

[0022] The coal loading car 80 is arranged on the rails 81 so as to be movable in the Z-axis direction on the upper surface of the ceiling portion 44 of the coking chamber 41. The coal loading car 80 includes a plurality of coal loading hoppers 82 arranged in the X-axis direction, and a fourth moving device 210. Each coal loading hopper 82 is arranged at a position corresponding to each coal loading port 46 in the X-axis direction. The coal loading car 80 moves to the vicinity of a coal supply device (not shown) and receives coal from the device into the coal loading hopper 82. The coal loading car 80 moves directly above any of the coking chambers 41, and loads a predetermined amount of coal from the coal loading hopper 82 into the coking chamber 41 through the coal loading port 46 of the coking chamber 41. The coal loading car 80 opens the lid of the coal loading port 46 before loading, and closes the lid after loading. The fourth moving device 210 includes a traveling motor. The coal loading car 80 has wheels 80w, and can move under its own power by rotating the wheels 80w using the traveling motor. The fourth mobile device 210 will be described later.

[0023] (1st moving device) The first moving device 110 will be described with reference to Figs. 1 and 2. Fig. 2 is a block diagram showing the first moving device 110. In Fig. 2, each arrow points from the supply source of the voltage of each part to the supply destination. In the first moving device 110, the moving part 10 is at least one of the pusher ram 54 and the leveling bar 56. In this example, both are retracted as the moving part 10.

[0024] The first movement device 110 includes a pantograph 192 that receives a voltage supplied to the trolley wire 190 from an external power source 20. The external power source 20 is a commercial power source or a power source generated by private power generation. The pantograph 192 is sometimes referred to as a trolley mechanism. As an example, an AC voltage V1 is supplied to the trolley wire 190 from the external power source 20. The AC voltage V1 is AC 440V or AC 400V. The AC voltage V1 is supplied to an uninterruptible power supply 132 and a rectifier 140, which will be described later.

[0025] The first moving device 110 includes a rectifier 140, a first converter 146, a first DC reactor 148, an inverter 150, and an electric motor 160. The inverter 150 includes a traveling inverter 152, a pushing inverter 154, and a leveling inverter 156. The electric motor 160 includes a traveling motor 162, a pushing motor 164, and a leveling motor 166. The rectifier 140 rectifies the AC voltage V1 supplied from the pantograph 192 using a diode, and supplies the DC voltage V2 to the first converter 146.

[0026] The first converter 146 converts the DC voltage V2 supplied from the rectifier 140 into a DC voltage V3 (e.g., 600 V) for driving the inverter, and supplies the DC voltage V3 to the inverter 150 via the drive line Ld. The first converter 146 uses a first DC reactor 148 to boost the input voltage and reduce pulsation of the DC voltage V3. The DC voltage V3 is also supplied to the second converter 126 and the lighting unit 172, which will be described later, via the drive line Ld.

[0027] The inverter 150 generates a three-phase AC voltage based on the DC voltage V3 supplied from the first converter 146, and supplies the three-phase AC voltage to the electric motor 160. The inverter 150 can be configured to include a three-phase bridge circuit made up of a plurality of switching elements.

[0028] The traveling inverter 152 supplies the generated three-phase AC voltage to the traveling motor 162 to rotate it. The traveling motor 162 rotates the wheels 50w to move the extrusion device 50 in the Z-axis direction.

[0029] The push-out inverter 154 supplies the generated three-phase AC voltage to the push-out motor 164 to rotate it. The push-out motor 164 moves the push-out ram 54 forward and backward in the X-axis direction via a pinion gear (not shown) and rack teeth (not shown).

[0030] The leveling inverter 156 supplies the generated three-phase AC voltage to a leveling motor 166 to rotate it. The leveling motor 166 moves the leveling bar 56 forward and backward in the X-axis direction via a wire (not shown).

[0031] The first movement device 110 further includes an uninterruptible power supply 132, a power outage detection unit 134, a control unit 130, a battery 120, an electromagnetic contactor 124, a second converter 126, and a second DC reactor 128. The battery 120 is a secondary battery that can be repeatedly charged and discharged. The battery 120 is provided separately from a secondary battery 132b included in the uninterruptible power supply 132, and has a larger discharge capacity and a higher output voltage than the secondary battery 132b.

[0032] First, a description will be given of the second converter 126 and the battery 120. The second converter 126 has a normal mode operation for charging the battery 120 and a power outage mode operation for converting the power of the battery 120 during a power outage.

[0033] In the steady mode operation, the second converter 126 steps down the DC voltage V3 supplied from the first converter 146 to the first terminal 126h via the drive line Ld to generate a DC voltage V4 (e.g., 30 V) and outputs it from the second terminal 126j. The second converter 126 steps down the DC voltage V3 to the DC voltage V4 and reduces pulsation of the DC voltage V4 using the second DC reactor 128. The second converter 126 supplies the DC voltage V4 to the battery 120 via the electromagnetic contactor 124 to charge the battery 120.

[0034] The electromagnetic contactor 124 functions as a relay that switches between a conductive state and a non-conductive state between the battery 120 and the second terminal 126j under the control of the control unit 130, which will be described later. In the steady mode operation, the battery 120 is charged by the DC voltage V4 supplied from the second converter 126 via the electromagnetic contactor 124.

[0035] In the power failure mode operation, the second converter 126 generates a DC voltage V5 (e.g., 600 V) by boosting the battery voltage Vb supplied from the battery 120 to the second terminal 126j via the electromagnetic contactor 124. The DC voltage V5 is supplied to the inverter 150 and the lighting unit 172 via the drive line Ld. In the power failure mode operation, the pushing inverter 154 and the leveling inverter 156 drive the pushing motor 164 and the leveling motor 166 based on the control of the control unit 130.

[0036] The lighting unit 172 functions as an interior light and a passage light for the work space 58s of the heat insulation chamber 58 of the extrusion device 50. The lighting unit 172 is turned on in accordance with the control of the control unit 130 based on the DC voltage V5. When the lighting unit 172 is turned on during a power outage, the interior and passage of the work space 58s become bright, making it easy for workers to work. The lighting unit 172 also functions as a light for photography for a camera (not shown) that monitors the work space 58s.

[0037] The uninterruptible power supply 132 will be described. The uninterruptible power supply 132 supplies an output voltage V6 based on an AC voltage V1 from the pantograph 192. The uninterruptible power supply 132 is a power supply device that continues to supply the output voltage V6 even when the input power from the pantograph 192 is cut off due to a power outage of the external power supply 20. The uninterruptible power supply 132 of this embodiment has a built-in rectifier (not shown), a secondary battery 132b, and an inverter (not shown), and rectifies the AC voltage V1 from the pantograph 192, and while charging the secondary battery 132b, the inverter constantly generates an output voltage V6 synchronized with the AC voltage V1. The output voltage V6 is supplied to the power outage detection unit 134, the control unit 130, the electromagnetic contactor 124, the second converter 126, and the like. The capacity of the secondary battery 132b of the uninterruptible power supply 132 is set according to the time required for the moving unit 10 to perform the evacuation operation.

[0038] The power failure detection unit 134 monitors the AC voltage V1 from the pantograph 192, detects a power failure (hereinafter referred to as a power failure) due to a power failure of the external power source 20 or a failure of the contact wire 190, and sends the detection result to the control unit 130. The power failure detection unit 134 of this embodiment may be configured with a programmable logic controller, a relay circuit, or the like.

[0039] The control unit 130 controls the electromagnetic contactor 124, the second converter 126, the first converter 146, the traveling inverter 152, the push-out inverter 154, the leveling inverter 156, and the lighting unit 172 based on the detection result obtained from the power outage detection unit 134. In particular, the control unit 130 controls these components to operate in a normal mode when there is no power outage. The control unit 130 controls these components to operate in a power outage mode when there is a power outage.

[0040] The evacuation operation will be described. When a power outage occurs, the first moving device 110 supplies the power of the battery 120 to the pushing motor 164 and the leveling motor 166 via the pushing inverter 154 and the leveling inverter 156, and controls these motors to move the pushing ram 54 or the leveling bar 56 in the evacuation direction. This evacuation direction refers to the direction in which the moving part 10 moves away from the high temperature in the furnace, and in this example, it is the direction from the carbonization chamber 41 toward the outside of the chamber. The first moving device 110 causes the pushing ram 54 or the leveling bar 56 to evacuate from the carbonization chamber 41 in the direction toward the outside of the chamber. By performing such an evacuation operation, it is possible to avoid the failure of the pushing ram 54 and the leveling bar 56 due to the heat of the high-temperature coke. After the first moving device 110 causes the pushing ram 54 or the leveling bar 56 to evacuate from the carbonization chamber 41, the first moving device 110 may control the traveling motor 162 to move the pushing device 50 in the Z-axis direction.

[0041] In the first movement device 110, even if the external power source 20 experiences a power outage, the output voltage V6 of the uninterruptible power supply 132 continues to be supplied for a predetermined period of time, so that the power outage detection unit 134, the control unit 130, the electromagnetic contactor 124 and the second converter 126 can continue to operate during that period.

[0042] When the power outage detection unit 134 detects a power outage, the control unit 130 performs the following control. (1) The control unit 130 controls the electromagnetic contactor 124 and the second converter 126 to supply a DC voltage V5 to the drive line Ld based on the battery voltage Vb. (2) The control unit 130 controls the push-out motor 164 via the push-out inverter 154 so that the push-out ram 54 moves from the carbonization chamber 41 toward the outside of the chamber. (3) The control unit 130 controls the leveling motor 166 via the leveling inverter 156 so that the leveling bar 56 moves from the carbonization chamber 41 toward the outside of the chamber. (4) The control unit 130 turns on the illumination unit 172 so as to illuminate a predetermined work area.

[0043] When the power outage is resolved, the control unit 130 controls the electromagnetic contactor 124, the second converter 126, the first converter 146, the inverter 150, and the lighting unit 172 so as to operate in the steady mode. This concludes the description of the first movement device 110.

[0044] (Second moving device) The second moving device 310 will be described with reference to Figs. 1 and 3. Components and members that are the same as or equivalent to those of the first moving device 110 are given the same reference numerals, and duplicated descriptions will be omitted. Fig. 3 is a block diagram that shows the second moving device 310. In the second moving device 310, the moving section 10 includes a guide car 60. In this example, the guide car 60 is caused to perform a retracting operation as the moving section 10.

[0045] The second moving device 310 differs from the first moving device 110 in that it does not have the push-out inverter 154, the leveling inverter 156, the push-out motor 164, the leveling motor 166, or the lighting unit 172, and the running motor 162 drives and rotates the wheels 60w to move the guide car 60 in the Z-axis direction.

[0046] The evacuation operation of the second moving device 310 will be described. If the hood 62 of the guide car 60 continues to be positioned above the bucket car 72 loaded with the high-temperature coke discharged from the carbonization chamber 41 for a long time due to a power outage, the hood 62 may deform and the guide car 60 may break down. For this reason, when a power outage occurs, the second moving device 310 supplies the power of the battery 120 to the traveling motor 162 via the traveling inverter 152 and controls this motor to move the guide car 60 in the evacuation direction. By performing such an evacuation operation, it is possible to avoid the breakdown of the guide car 60 due to the heat of the high-temperature coke. In this example, the second moving device 310 moves the guide car 60 in the Z-axis direction to a position where the hood 62 leaves the space above the bucket car 72 and the influence of the heat of the high-temperature coke can be substantially avoided.

[0047] When the power outage detection unit 134 detects a power outage, the control unit 130 performs the following control. (1) The control unit 130 controls the electromagnetic contactor 124 and the second converter 126 to supply a DC voltage V5 to the drive line Ld based on the battery voltage Vb. (2) The control unit 130 controls the traveling motor 162 via the traveling inverter 152 so that the hood 62 moves in a direction away from the space above the bucket cart 72.

[0048] When the power outage is resolved, the control unit 130 controls the electromagnetic contactor 124, the second converter 126, the first converter 146, and the traveling inverter 152 so as to operate in the steady mode. This concludes the description of the second movement device 310.

[0049] (Third mobile device) The third movement device 410 will be described with reference to Fig. 1 and Fig. 4. Components and members that are the same as or equivalent to those of the first movement device 110 are given the same reference numerals, and duplicated descriptions will be omitted. Fig. 4 is a block diagram that shows the third movement device 410. In the third movement device 410, the movement section 10 includes a bucket vehicle 70. In this example, the bucket vehicle 70 is caused to perform a retraction operation as the movement section 10.

[0050] The third moving device 410 differs from the first moving device 110 in that it does not have the push-out inverter 154, the leveling inverter 156, the push-out motor 164, the leveling motor 166, or the lighting unit 172, and the traveling motor 162 drives and rotates the wheels 73w, and the bucket truck 70 is towed by the towing vehicle 73 to move in the Z-axis direction.

[0051] The retraction operation of the third movement device 410 will be described. If the bucket car 72 loaded with high-temperature coke remains under the hood 62 for a long time due to a power outage, the hood 62 may be deformed and the guide car 60 may break down. For this reason, when a power outage occurs, the third movement device 410 supplies power from the battery 120 to the traveling motor 162 via the traveling inverter 152, and controls this motor to move the towing vehicle 73 and the bucket car 70 in the Z-axis direction. By performing such an operation, it is possible to avoid a breakdown of the guide car 60 due to the heat of the high-temperature coke. In this example, the third movement device 410 moves the towing vehicle 73 and the bucket car 70 in the Z-axis direction to a position where the bucket car 72 leaves the space under the hood 62 and is not substantially affected by the heat of the high-temperature coke.

[0052] When the power outage detection unit 134 detects a power outage, the control unit 130 performs the following control. (1) The control unit 130 controls the electromagnetic contactor 124 and the second converter 126 to supply a DC voltage V5 to the drive line Ld based on the battery voltage Vb. (2) The control unit 130 controls the traveling motor 162 via the traveling inverter 152 so that the bucket truck 72 moves in a direction away from the space below the hood 62.

[0053] When the power outage is resolved, the control unit 130 controls the electromagnetic contactor 124, the second converter 126, the first converter 146, and the traveling inverter 152 so as to operate in the steady mode. This concludes the description of the third movement device 410.

[0054] (4th mobile device) The fourth movement device 210 will be described with reference to Fig. 1 and Fig. 5. Components and members that are the same as or equivalent to those of the first movement device 110 are given the same reference numerals, and duplicated explanations will be omitted. Fig. 5 is a block diagram that shows the fourth movement device 210. In the fourth movement device 210, the movement section 10 includes a coal loading car 80. In this example, the coal loading car 80 is used as the movement section 10 and is caused to move away.

[0055] The fourth moving device 210 differs from the first moving device 110 in that it does not have a pushing inverter 154, a leveling inverter 156, a pushing motor 164, a leveling motor 166, or a lighting unit 172, and the traveling motor 162 drives and rotates the wheels 80w to move the coal loading car 80 in the Z-axis direction.

[0056] The retraction operation of the fourth moving device 210 will be described. As described above, after the coal is loaded into the carbonization chamber 41, the lid of the coal loading port 46 is closed by the coal loading car 80. After the lid is closed, plaster is applied around the lid to seal it. However, when the lid is closed, the lid may not be closed properly, and a gap may be formed between the lid and the coal loading port 46. In this case, high-temperature flames may blow out from the gap between the lid and the coal loading port 46. If a flame blows out from the coal loading port 46 when the coal loading hopper 82 of the coal loading car 80 is located above the coal loading port 46 due to a power outage, the coal loading hopper 82 may break down.

[0057] For this reason, when a power outage occurs, the fourth movement device 210 supplies power from the battery 120 to the traveling motor 162 via the traveling inverter 152 and controls this motor to move the coal loading car 80 in the evacuation direction. By performing such an evacuation operation, it is possible to avoid damage to the coal loading car 80 due to high-temperature flames. In this example, the fourth movement device 210 moves the coal loading car 80 in the Z-axis direction to a position where the coal loading car 80 leaves the space above the coal loading port 46 and can substantially avoid the effects of the high-temperature flames from the coal loading port 46.

[0058] When the power outage detection unit 134 detects a power outage, the control unit 130 performs the following control.

In this case, the guide car 60 can be moved away from the high-temperature bucket car 70 when a power outage occurs.

[0064] The moving unit 10 includes a bucket car 70 that receives the coke discharged from the carbonization chamber 41 of the coke oven 40 via the guide car 60, and the control unit 130 controls the electric motor 160 to move the bucket car 70 away from the guide car 60 when a power outage occurs. In this case, the high-temperature bucket car 70 can be separated from the guide car 60 when a power outage occurs.

[0065] The moving unit 10 includes a coal loading car 80 that loads coal from a coal loading port 46 of the carbonization chamber 41 of the coke oven 40, and the control unit 130 controls the electric motor 160 to move the coal loading car 80 away from the coal loading port 46 when a power outage occurs. In this case, the coal loading car 80 can be moved away from the high-temperature coal loading port 46 when a power outage occurs.

[0066] The device further includes a lighting unit 172 that illuminates the work space or passageway with power supplied from the external power source 20, and when the external power source 20 experiences a power outage, the control unit 130 supplies power from the battery 120 to the lighting unit 172 to turn on the lighting unit 172. In this case, during a power outage, the lighting unit 172 can brighten the work space 58s, making it easy to work.

[0067] In addition to the battery 120, a secondary battery 132b that is a repeatedly chargeable and dischargeable battery and is charged by the external power source 20 is provided, and when the external power source 20 experiences a power outage, the control unit 130 operates using the power of the separate battery 120. In this case, when a power outage occurs, the control unit 130 can continue to operate because it receives power from the secondary battery 132b.
