Description

本発明は、積雪する寒冷地などにおいて、軌道面が滑り易い雪氷状態になることを防止するために、軌道面に対して液状凍結防止剤を供給する液状凍結防止剤供給装置、及び液状凍結防止剤供給方法に関するものである。   The present invention relates to a liquid anti-freezing agent supply device that supplies a liquid anti-freezing agent to a raceway surface and a liquid anti-freezing prevention in order to prevent the raceway surface from becoming a slippery snow-ice state in a cold region where snow is accumulated. The present invention relates to an agent supply method.

従来、定位置設置式の液状凍結防止剤供給装置として、例えば、特許文献１、２、３、４、５、６、７、８に記載されたものが提案されている。これらの技術においては、軌道面（路面）近傍の定位置に設置された液状凍結防止剤供給装置からの液状凍結防止剤は、軌道面に埋設されたノズル又は軌道面の脇に設置されたノズルを介して、浸み出したり又は噴射されて、軌道面に供給され、軌道面が滑り易い雪氷状態になることを防止する。
また、凍結防止剤供給装置を積載した車両により軌道面に凍結防止剤の全面散布を行う移動散布方式として、例えば、特許文献９、１０、１１に記載されたように、粒状凍結防止剤を軌道面の全域に散布することにより、軌道面が滑り易い雪氷状態になることを防止するものが提案されている。 Conventionally, as a fixed-position installation type liquid antifreeze supply device, for example, those described in Patent Documents 1, 2, 3, 4, 5, 6, 7, and 8 have been proposed. In these technologies, the liquid antifreezing agent from the liquid antifreezing agent supply device installed at a fixed position near the raceway surface (road surface) is a nozzle embedded in the raceway surface or a nozzle installed beside the raceway surface. The leaching or jetting is supplied to the raceway surface to prevent the raceway surface from becoming slippery snow and ice.
Further, as a moving spraying method for spraying the entire surface of the antifreeze agent on the track surface by the vehicle loaded with the antifreeze supply device, for example, as described in Patent Documents 9, 10, and 11, the granular antifreeze agent is tracked. It has been proposed to prevent the raceway surface from becoming slippery snow and ice by spreading over the entire surface.

しかしながら、特許文献１〜８に記載されたような定位置設置式の液状凍結防止剤供給装置では、車両の車輪によって液状凍結防止剤が引きずられて拡散する範囲には、限界がある。また、長距離区間の軌道面への対応には、多大な費用を必要とする。
また、液状凍結防止剤供給装置のような大掛かりな装置（特に液状凍結防止剤の貯留タンク）を配置することのできないトンネル内、橋梁上への適用や、景観、視界の確保等が必要な箇所への適用や、液状凍結防止剤供給装置の設置スペースが狭小なその他の箇所への適用が困難である。
更に、軌道管理の必要性の変化に応じて、液状凍結防止剤供給装置の移設、増設、撤去等を行う場合には、新たな設置スペースの確保が必要であるとともに、多大な費用が必要になる。 However, in the fixed-position installation type liquid antifreezing agent supply apparatus as described in Patent Documents 1 to 8, there is a limit to the range in which the liquid antifreezing agent is dragged and diffused by the vehicle wheel. In addition, a great deal of cost is required to deal with the track surface of a long-distance section.
In addition, large-scale devices such as liquid anti-freezing agent supply devices (particularly liquid anti-freezing agent storage tanks) cannot be placed in tunnels, on bridges, and where landscape and visibility must be secured It is difficult to apply to other places where the installation space of the liquid antifreezing agent supply device is narrow.
Furthermore, when the liquid cryoprotectant supply device is relocated, expanded, or removed in accordance with changes in the need for track management, it is necessary to secure a new installation space and a large amount of cost. Become.

また、特許文献９〜１１に記載されたような粒状凍結防止剤供給装置を積載した車両により軌道面に全面散布を行う移動散布方式では、専用の車両を必要とし、多大な費用が必要となる。鉄道の軌道面の幅は狭いため、軌道面以外へ粒状凍結防止剤が無駄に散布される。
更に、粒状凍結防止剤を鉄道の軌道面に散布する場合には、粒状凍結防止剤が風などにより飛散しやすいため、粒状凍結防止剤を軌道面へ定着させることが困難である。 Further, in the moving spraying method in which the entire surface is sprayed on the track surface by the vehicle loaded with the granular antifreeze supply device as described in Patent Documents 9 to 11, a dedicated vehicle is required and a great amount of cost is required. . Since the width of the railroad track surface is narrow, the granular antifreeze is sprayed unnecessarily outside the track surface.
Further, when the granular antifreeze agent is sprayed on the railroad track surface, it is difficult to fix the granular antifreeze agent on the track surface because the granular antifreeze agent is likely to be scattered by wind or the like.

また、散布される液状凍結防止剤は、予期せぬ飛散により鉄道車両の電気制御系統へ悪影響を与えないように、導電性が低いことが必要である。また、散布される液状凍結防止剤は、橋梁や軌道の鉄類や軌道周辺の環境へ悪影響を与えないことが必要である。   Moreover, the liquid antifreezing agent to be sprayed needs to have low conductivity so as not to adversely affect the electric control system of the railway vehicle due to unexpected scattering. Moreover, it is necessary that the liquid antifreezing agent to be sprayed does not adversely affect the bridge, the iron on the track, and the environment around the track.

従って、本発明は、液状凍結防止剤供給装置を、車体の内部の別の箇所に移動したり、又は車体の内部から外部へ移動可能であり、また、液状凍結防止剤供給装置を設置したり、移動したり、撤去することが容易な液状凍結防止剤供給装置、及び液状凍結防止剤供給方法を提供することを目的とする。   Therefore, the present invention can move the liquid anti-freezing agent supply device to another location inside the vehicle body, or can be moved from the inside of the vehicle body to the outside, and the liquid anti-freezing agent supply device can be installed. An object of the present invention is to provide a liquid anti-freezing agent supply apparatus and a liquid anti-freezing agent supply method that can be easily moved or removed.

本発明の液状凍結防止剤供給装置は、鉄道車両の車体の内部に設置される液状凍結防止剤供給装置であって、前記車体の下部に設けられた噴射ノズル部に向けて液状凍結防止剤が流通する送液管と前記液状凍結防止剤供給装置との接続及び切り離しが可能な接続切り離し機構を備え、前記接続切り離し機構によって前記送液管から前記液状凍結防止剤供給装置を切り離すことが可能である、ことを特徴とする。   The liquid antifreezing agent supply apparatus according to the present invention is a liquid antifreezing agent supply apparatus installed inside a vehicle body of a railway vehicle, and the liquid antifreezing agent is directed toward an injection nozzle portion provided at a lower portion of the vehicle body. A connection / disconnection mechanism capable of connecting and disconnecting the liquid feeding pipe that circulates and the liquid anti-freezing agent supply apparatus is provided, and the liquid anti-freezing agent supply apparatus can be separated from the liquid feeding pipe by the connection / disconnection mechanism. It is characterized by that.

そのため、積雪が有る寒冷季節以外の不必要時や緊急対応時には、接続切り離し機構によって送液管から液状凍結防止剤供給装置を切り離すことにより、液状凍結防止剤供給装置を、車体の内部の別の箇所に移動したり、又は車体の内部から外部へ移動可能である。また、液状凍結防止剤供給装置を設置したり、移動したり、撤去することが容易であるため、液状凍結防止剤供給装置を積載した専用車両を必要とすることなく、多大な費用を必要としない。   For this reason, when it is not necessary during a cold season with snow or when it is necessary to respond urgently, the liquid anti-freezing agent supply device is separated from the liquid feed pipe by using a connection disconnecting mechanism. It is possible to move to a place or move from the inside of the vehicle body to the outside. In addition, since it is easy to install, move, or remove the liquid antifreeze supply device, it does not require a dedicated vehicle loaded with the liquid antifreeze supply device, and requires a large amount of cost. do not do.

また、本発明において、液状凍結防止剤を貯留する貯留タンク部と、前記送液管及び前記噴射ノズル部を介して前記貯留タンク部における液状凍結防止剤を軌道面へ供給するために液状凍結防止剤を加圧する加圧送液部と、前記加圧送液部を制御する液供給制御部と、を備え、前記加圧送液部は、加圧送液ポンプを備え、前記液供給制御部は、前記加圧送液ポンプで加圧された液状凍結防止剤を、前記送液管及び前記噴射ノズル部を介して軌道面に連続又は断続で噴射して供給するように、前記加圧送液部を制御してもよい。   Further, in the present invention, the liquid tank is configured to store the liquid antifreeze agent, and the liquid antifreeze agent is supplied to the raceway surface through the liquid supply pipe and the injection nozzle unit. A pressurized liquid feeding unit that pressurizes the agent; and a liquid supply control unit that controls the pressurized liquid feeding unit. The pressurized liquid feeding unit includes a pressurized liquid feeding pump, and the liquid supply control unit includes the pressurizing liquid feeding unit. Controlling the pressurized liquid feeding section so that the liquid antifreezing agent pressurized by the pressure liquid feeding pump is continuously or intermittently sprayed and supplied to the raceway surface via the liquid feeding pipe and the jet nozzle section; Also good.

また、本発明において、各種外部状況を検出するセンサー部と、液状凍結防止剤を貯留する貯留タンク部と、噴射電動弁を有する加圧送液部であって、前記送液管及び前記噴射ノズル部を介して前記貯留タンク部における液状凍結防止剤を軌道面へ供給するために前記噴射電動弁を開放した状態で液状凍結防止剤を加圧する加圧送液部と、前記センサー部の検出結果に応じて、前記加圧送液部の前記噴射電動弁の開放時間及び開放間隔を制御する液供給制御部と、を備え、前記加圧送液部は、加圧送液ポンプと噴射圧力調整器とを更に備え、前記液供給制御部は、前記加圧送液ポンプで加圧された液状凍結防止剤であって前記噴射圧力調整器及び前記貯留タンク部により一定圧力に維持された液状凍結防止剤を、前記噴射電動弁、前記送液管及び前記噴射ノズル部を介して、軌道面に連続又は断続で噴射して供給するように、前記加圧送液部を制御してもよい。   Further, in the present invention, a sensor part for detecting various external situations, a storage tank part for storing a liquid antifreezing agent, and a pressurized liquid feeding part having an injection motor operated valve, wherein the liquid feeding pipe and the injection nozzle part In response to the detection result of the sensor unit, and a pressurized liquid feeding unit that pressurizes the liquid cryoprotectant with the injection motor-operated valve opened to supply the liquid cryoprotectant in the storage tank unit to the raceway surface via A liquid supply control unit that controls an opening time and an opening interval of the injection motor-operated valve of the pressurized liquid feeding unit, and the pressurized liquid feeding unit further includes a pressurized liquid feeding pump and an injection pressure regulator. The liquid supply control unit injects the liquid antifreeze agent pressurized by the pressurizing pump and maintained at a constant pressure by the injection pressure regulator and the storage tank unit. Motorized valve, liquid feeding pipe Through fine the injection nozzle unit, to supply to the injection in a continuous or intermittent on the raceway surface, may control the pressure pumping liquid portion.

この場合、気象状況により変化する軌道面に、効率的に液状凍結防止剤を供給することができる。また、噴射圧力調整器で液状凍結防止剤の噴射圧力を調整することにより、軌道面への噴射供給量を増減し、液状凍結防止剤の供給過多及び供給過少を抑制することができる。   In this case, the liquid antifreeze agent can be efficiently supplied to the track surface that changes depending on weather conditions. Further, by adjusting the injection pressure of the liquid antifreeze agent with the injection pressure adjuster, it is possible to increase or decrease the injection supply amount to the raceway surface, and to suppress the excessive supply and the insufficient supply of the liquid antifreeze agent.

また、本発明において、前記噴射ノズル部は、噴射ノズルを、車両の車輪の位置及び車輪の幅に応じて１個又は複数個備え、前記噴射ノズルそれぞれに対して逆流防止弁を備えていてもよい。   In the present invention, the injection nozzle unit may include one or a plurality of injection nozzles according to the position of the vehicle wheel and the width of the vehicle, and a backflow prevention valve for each of the injection nozzles.

この場合、軌道面以外への液状凍結防止剤の無駄な散布を抑制することができる。また、噴射停止時に噴射ノズルから空気が進入することによる液垂れの発生を抑制することができ、液状凍結防止剤の無駄を抑制することができる。   In this case, useless spraying of the liquid antifreeze agent to other than the raceway surface can be suppressed. In addition, it is possible to suppress the occurrence of liquid dripping due to air entering from the injection nozzle when the injection is stopped, and it is possible to suppress the waste of the liquid antifreeze agent.

また、本発明の液状凍結防止剤供給方法は、前記液状凍結防止剤供給装置を使用して、前記噴射ノズル部を、軌道面の上方の位置であって、軌道面に対して下方に液状凍結防止剤を噴射する位置に配置して、軌道面に液状凍結防止剤を供給することを特徴とする。   In the liquid antifreeze supplying method of the present invention, the liquid antifreeze supplying apparatus is used to place the injection nozzle portion in a liquid freezing position at a position above the track surface and below the track surface.

鉄道は、広く解釈され、１本又は複数本の鉄製の軌条（レール）又はそれに代わる物を案内路（特に軌道）として、車輪を有する車両が走行する交通機関である。鉄道車両は、広く解釈され、鉄製の軌道（特にレール、案内軌条）以外の軌道（例えば、コンクリート製の軌道）を走行する車両を含む。軌道面は、軌道における車輪が接触する面である。車両の車輪は、金属製の車輪に制限されず、タイヤ製の車輪も含む。   A railroad is widely understood as a transportation facility in which a vehicle having wheels travels using one or a plurality of iron rails (rails) or alternatives as guideways (especially tracks). Railroad vehicles are widely interpreted and include vehicles that travel on tracks (for example, concrete tracks) other than iron tracks (especially rails and guide rails). The track surface is a surface with which the wheels in the track contact. The wheels of the vehicle are not limited to metal wheels, but also include tire wheels.

図１及び図２に示すように、車体２の下部の外部には、噴射ノズル部５が設けられている。車体２の下部の外部と車体２の内部とに跨がって、送液管６が設けられている。送液管６には、液状凍結防止剤供給装置４から噴射ノズル部５へ向けて液状凍結防止剤が流通する。液状凍結防止剤供給装置４は、送液管６と液状凍結防止剤供給装置４との接続及び切り離しが可能な接続切り離し機構７を備える。液状凍結防止剤は、接続切り離し機構７及び送液管６を介して、噴射ノズル部５に送液される。接続切り離し機構７によって、送液管６と液状凍結防止剤供給装置４とを接続したり、切り離したりすることが可能である。接続切り離し機構７は、送液管６の上端部（上流側の端部でもある）に設けられる。接続切り離し機構７の構成は制限されない。送液管６の下端部（下流側の端部でもある）の周辺は、車体２の外部（の下部）に配置されている。液状凍結防止剤供給装置４、及び送液管６の大部分（下端部の周辺以外の部分）は、車体２の内部に配置される。   As shown in FIGS. 1 and 2, an injection nozzle portion 5 is provided outside the lower portion of the vehicle body 2. A liquid feeding pipe 6 is provided across the outside of the lower portion of the vehicle body 2 and the inside of the vehicle body 2. In the liquid feed pipe 6, the liquid antifreeze agent flows from the liquid antifreeze supply device 4 toward the injection nozzle unit 5. The liquid antifreezing agent supply device 4 includes a connection / disconnection mechanism 7 capable of connecting and disconnecting the liquid feeding pipe 6 and the liquid antifreezing agent supply device 4. The liquid antifreezing agent is fed to the injection nozzle unit 5 through the connection / disconnection mechanism 7 and the liquid feeding pipe 6. It is possible to connect or disconnect the liquid feeding pipe 6 and the liquid antifreezing agent supply device 4 by the connection / disconnection mechanism 7. The connection disconnection mechanism 7 is provided at the upper end portion (also an upstream end portion) of the liquid feeding pipe 6. The configuration of the connection disconnection mechanism 7 is not limited. The periphery of the lower end portion (which is also an end portion on the downstream side) of the liquid feeding pipe 6 is disposed outside (the lower portion of) the vehicle body 2. Most of the liquid antifreezing agent supply device 4 and the liquid feeding pipe 6 (portions other than the periphery of the lower end portion) are arranged inside the vehicle body 2.

液状凍結防止剤供給装置４は、軌道面１を進行する鉄道車両の車体２の運転室の通路に設置される。噴射ノズル部５は、軌道面１の上方（詳細には真上）の位置であって、軌道面１に対して下方（詳細には垂直下方向）に液状凍結防止剤１０１を噴射する位置に配置される。噴射ノズル部５の位置は、車両の走行の障害を発生しない範囲において軌道面１に近接していることが好ましい。
接続切り離し機構７によって送液管６から液状凍結防止剤供給装置４を切り離すことにより、液状凍結防止剤供給装置４は、移動や撤去が可能になる。噴射ノズル部５から軌道面１に噴射された液状凍結防止剤１０１は、車輪３により、軌道面１に拡散された後に滞留し、軌道面１が滑り易い雪氷状態になることを防止する。 The liquid antifreezing agent supply device 4 is installed in the passage of the cab of the vehicle body 2 of the railway vehicle traveling on the raceway surface 1. The injection nozzle portion 5 is located above (in detail, directly above) the raceway surface 1 and at a position for injecting the liquid antifreezing agent 101 downward (in detail, vertically downward) with respect to the raceway surface 1. Be placed. It is preferable that the position of the injection nozzle unit 5 is close to the track surface 1 in a range in which no obstacles to vehicle travel occur.
