JP 2001-0779445 (abstract) JP2003-120200A (abstract)

ここで、この種の集塵機の運転状態は、通常、手動によるスイッチ操作に応じて制御され、あるいは粉塵を検出するダストセンサの検出信号に応じて制御されている。   Here, the operating state of this type of dust collector is usually controlled in accordance with a manual switch operation, or controlled in accordance with a detection signal of a dust sensor that detects dust.

ところで、手動によるスイッチ操作に応じて集塵機の運転状態を制御する場合、粉塵の発生が予測される特定の作業工程ごとに粉塵量に応じて集塵機の運転状態をこまめに制御することは甚だ面倒である。このため、手動によるスイッチ操作の場合には、往々にして集塵機を無駄に連続運転させてしまうことがあり、その結果、エネルギコストが上昇してしまうという問題がある。   By the way, when controlling the operation state of the dust collector according to the manual switch operation, it is very troublesome to frequently control the operation state of the dust collector according to the amount of dust for each specific work process where dust generation is predicted. is there. For this reason, in the case of manual switch operation, there is often a problem that the dust collector is unnecessarily continuously operated, resulting in an increase in energy cost.

以上のように構成された一実施形態の集塵機の運転制御装置は、トンネルの掘削工事において発生する粉塵を回収する集塵機１を効率的かつ経済的に運転させるために使用されるのであり、トンネルの掘削工事は、「削孔作業工程」→「装薬作業工程」→「発破作業工程」→「ずり出し作業工程」→「当り取り作業工程」→「支保工設置作業工程」→「吹付け作業工程」→「ロックボルトの順送り作業工程」という標準的な一連の作業工程を経て進められる。   The dust collector operation control device according to the embodiment configured as described above is used to efficiently and economically operate the dust collector 1 that collects dust generated during tunnel excavation work. Excavation work is as follows: “Drilling work process” → “Charge work process” → “Blasting work process” → “Slip-out work process” → “Batch work process” → “Support construction installation work process” → “Blowing work” The process proceeds through a standard series of work processes, “process” → “sequential work process of rock bolts”.

ここで、本実施形態の集塵機の運転制御装置では、トンネルの掘削工事が「削孔作業工程」および「装薬作業工程」にある間は、集塵機１の運転が休止又は低速運転されている。そして、トンネルの掘削工事が「発破作業工程」に進んでトンネルの切羽が発破されると、その発破作業に伴う爆風の瞬間的な微小流量を発破作業工程検出センサ３が検知し、その検知信号が「発破作業工程」の検出信号として制御装置２の送信部２Ａの無線送信機２Ａ３に出力される。   Here, in the operation control apparatus for the dust collector of the present embodiment, the operation of the dust collector 1 is stopped or operated at a low speed while the tunnel excavation work is in the “drilling work process” and the “charge work process”. When the tunnel excavation work proceeds to the “blasting work process” and the tunnel face is blasted, the blasting work process detection sensor 3 detects an instantaneous minute flow rate of the blast accompanying the blasting work, and the detection signal Is output to the wireless transmitter 2A3 of the transmission unit 2A of the control device 2 as a detection signal of the “blasting operation process”.

すると、制御装置２の送信部２Ａの無線送信機２Ａ３から受信部２Ｂの無線受信機２Ｂ１に「発破作業工程」の検出信号が送信され、無線受信機２Ｂ１から風量制御盤２Ｂ２および主制御盤２Ｂ３に所定の制御信号が出力されることにより、集塵機１の吸引ファンが例えば１５分間だけ回転駆動され、その回転数が例えば５０Ｈｚの出力周波数で適切にインバータ制御される。その結果、「発破作業工程」の開始から例えば１５分間、トンネルの切羽付近で発生した粉塵が風管７を介して集塵機１に回収される。   Then, the detection signal of the “blasting operation process” is transmitted from the wireless transmitter 2A3 of the transmitter 2A of the control device 2 to the wireless receiver 2B1 of the receiver 2B, and the air volume control panel 2B2 and the main control panel 2B3 are transmitted from the wireless receiver 2B1. When a predetermined control signal is output to the suction fan, the suction fan of the dust collector 1 is rotationally driven, for example, for 15 minutes, and the rotational speed thereof is appropriately inverter-controlled at an output frequency of, for example, 50 Hz. As a result, dust generated near the face of the tunnel for 15 minutes, for example, from the start of the “blasting operation process” is collected by the dust collector 1 through the wind tube 7.

次に、トンネルの掘削工事が「発破作業工程」から「ずり出し作業工程」へ進み、発破された大きな岩石をベルトコンベアで運べる大きさに破砕するクラッシャー１０が稼動すると、その分電盤１０Ａを流れるクラッシャー１０の稼動電流がずり出し作業工程検出センサ４により検知され、その検知信号が「ずり出し作業工程」の検出信号として制御装置２の送信部２Ａの無線送信機２Ａ３に電流検出器２Ａ１を介して出力される。   Next, when the tunnel excavation work proceeds from the “blasting work process” to the “push-out work process” and the crusher 10 that crushes the blasted large rock into a size that can be carried by a belt conveyor is activated, the distribution board 10A is moved. The operating current of the flowing crusher 10 is detected by the projecting work process detection sensor 4, and the detected signal is sent to the wireless transmitter 2A3 of the transmission unit 2A of the control device 2 as a detection signal of the "projecting work process". Is output via.

すると、制御装置２の送信部２Ａの無線送信機２Ａ３から制御装置２の受信部２Ｂの無線受信機２Ｂ１に「ずり出し作業工程」の検出信号が送信され、無線受信機２Ｂ１から風量制御盤２Ｂ２および主制御盤２Ｂ３に所定の制御信号が出力されることにより、集塵機１の吸引ファンが例えばクラッシャー１０の運転開始３０秒後から運転終了後１５分までの間回転駆動され、その回転数が例えば４０Ｈｚの出力周波数で適切にインバータ制御される。その結果、「ずり出し作業工程」におけるクラッシャー１０の運転開始３０秒後から運転終了後１５分までの間、クラッシャー１０付近で発生した粉塵が風管７を介して集塵機１に回収される。   Then, the detection signal of the “slip-out operation process” is transmitted from the wireless transmitter 2A3 of the transmission unit 2A of the control device 2 to the wireless receiver 2B1 of the reception unit 2B of the control device 2, and the air volume control panel 2B2 is transmitted from the wireless receiver 2B1. When a predetermined control signal is output to the main control panel 2B3, the suction fan of the dust collector 1 is driven to rotate, for example, from 30 seconds after the start of the operation of the crusher 10 to 15 minutes after the operation ends. The inverter is appropriately controlled at an output frequency of 40 Hz. As a result, the dust generated in the vicinity of the crusher 10 is collected by the dust collector 1 through the wind tube 7 from 30 seconds after the operation start of the crusher 10 in the “slip-out operation process” until 15 minutes after the operation is completed.

続いて、トンネルの掘削工事が「ずり出し作業工程」から「当り取り作業工程」へ進み、発破されたトンネルの切羽を所定形状に整形するために油圧ブレーカ１１の油圧装置が運転されると、その油圧装置の運転が当り取り作業工程検出センサ５を構成する無線送信機５Ａにより検出され、その検出信号が当り取り作業工程の検出信号として制御装置２の送信部２Ａの無線送信機２Ａ３に無線受信機５Ｂを介して出力される。   Subsequently, the excavation work of the tunnel proceeds from the “slip-out work process” to the “scoring work process”, and when the hydraulic device of the hydraulic breaker 11 is operated in order to shape the face of the blasted tunnel into a predetermined shape, The operation of the hydraulic device is detected by a wireless transmitter 5A constituting the winning work process detection sensor 5, and the detected signal is wirelessly transmitted to the wireless transmitter 2A3 of the transmitter 2A of the control device 2 as a detection signal of the winning work process. It is output via the receiver 5B.

すると、制御装置２の送信部２Ａの無線送信機２Ａ３から受信部２Ｂの無線受信機２Ｂ１に「当り取り作業工程」の検出信号が送信され、無線受信機２Ｂ１から風量制御盤２Ｂ２および主制御盤２Ｂ３に所定の制御信号が出力されることにより、集塵機１の吸引ファンが例えば油圧ブレーカ１１の運転開始から運転終了後１５分までの間回転駆動され、その回転数が例えば５５Ｈｚの出力周波数で適切にインバータ制御される。その結果、「当り取り作業工程」における油圧ブレーカ１１の運転開始から運転終了後１５分までの間、油圧ブレーカ１１付近で発生した粉塵が風管７を介して集塵機１に回収される。   Then, a detection signal of the “obtaining work process” is transmitted from the wireless transmitter 2A3 of the transmitter 2A of the control device 2 to the wireless receiver 2B1 of the receiver 2B, and the air volume control panel 2B2 and the main control panel are transmitted from the wireless receiver 2B1. By outputting a predetermined control signal to 2B3, the suction fan of the dust collector 1 is driven to rotate, for example, from the start of operation of the hydraulic breaker 11 to 15 minutes after the end of operation, and the number of rotations is appropriately set at an output frequency of 55 Hz, for example. Inverter controlled. As a result, the dust generated in the vicinity of the hydraulic breaker 11 is collected by the dust collector 1 through the wind pipe 7 from the start of operation of the hydraulic breaker 11 in the “cooking work process” to 15 minutes after the end of the operation.

ここで、トンネルの掘削工事が「当り取り作業工程」の次の「支保工設置作業工程」にある間は、集塵機１の運転が休止又は低速運転されている。そして、トンネルの掘削工事が「支保工設置作業工程」から「吹付け作業工程」へ進み、掘削されたトンネルの壁面に速乾性のコンクリートを吹き付ける吹付機１２が稼動すると、その分電盤１２Ａを流れる吹付機１２の稼動電流が吹付け作業工程検出センサ６により検知され、その検知信号が「吹付け作業工程」の検出信号として制御装置２の送信部２Ａの無線送信機２Ａ３に電流検出器２Ａ２を介して出力される。   Here, while the tunnel excavation work is in the “support work installation work process” after the “scoring work process”, the operation of the dust collector 1 is stopped or operated at a low speed. Then, when the tunnel excavation work proceeds from the “support work installation work process” to the “spraying work process” and the spraying machine 12 for spraying quick-drying concrete onto the wall surface of the excavated tunnel is operated, the distribution board 12A is installed. The operating current of the flowing sprayer 12 is detected by the spraying work process detection sensor 6, and the detection signal is detected as a detection signal of “spraying work process” by the wireless transmitter 2A3 of the transmission unit 2A of the control device 2 and the current detector 2A2. Is output via.

すると、制御装置２の送信部２Ａの無線送信機２Ａ３から制御装置２の受信部２Ｂの無線受信機２Ｂ１に吹付け作業工程の検出信号が送信され、無線受信機２Ｂ１から風量制御盤２Ｂ２および主制御盤２Ｂ３に所定の制御信号が出力されることにより、集塵機１の吸引ファンが例えば吹付機１２の運転開始３０秒後から運転終了後１０分までの間回転駆動され、その回転数が例えば５５Ｈｚの出力周波数で適切にインバータ制御される。その結果、「吹付け作業工程」における吹付機１２の運転開始３０秒後から運転終了後１０分までの間、吹付機１２付近で発生した粉塵が風管７を介して集塵機１に回収される。   Then, the detection signal of the blowing operation process is transmitted from the wireless transmitter 2A3 of the transmission unit 2A of the control device 2 to the wireless receiver 2B1 of the reception unit 2B of the control device 2, and the air volume control panel 2B2 and the main flow control panel 2B2 are transmitted from the wireless receiver 2B1. By outputting a predetermined control signal to the control panel 2B3, the suction fan of the dust collector 1 is driven to rotate, for example, from 30 seconds after the start of the operation of the sprayer 12 to 10 minutes after the end of the operation, and the rotational speed thereof is, for example, 55 Hz. The inverter is appropriately controlled at the output frequency. As a result, the dust generated in the vicinity of the sprayer 12 is collected by the dust collector 1 through the wind tube 7 from 30 seconds after the start of the operation of the sprayer 12 in the “spraying operation process” to 10 minutes after the end of the operation. .

すなわち、本実施形態の集塵機の運転制御装置によれば、トンネル掘削工事における一連の作業工程のうち、粉塵が発生する「発破作業工程」、「ずり出し作業工程」、「当り取り作業工程」および「吹付け作業工程」では、集塵機１がそれぞれ所定時間だけ運転され、その他の作業工程では集塵機１の運転が休止又は低速運転されるため、集塵機１を効率的かつ経済的に運転することができる。   That is, according to the operation control device of the dust collector of the present embodiment, among the series of work processes in tunnel excavation work, the “blasting work process”, the “slip-out work process”, the “scoring work process” in which dust is generated, In the “spraying operation process”, the dust collector 1 is operated for a predetermined time, and in other operation processes, the operation of the dust collector 1 is stopped or operated at a low speed. Therefore, the dust collector 1 can be operated efficiently and economically. .
