본 고안은 기관차의 살사(撒砂) 방향 선택장치에 관한 것으로서, 살사장치의 구조를 기관사가 푸트밸브만 접촉하게 되면 통상의 기관차 구동제어장치측에 의해 작동되는 변환밸브에 의해 차체 진행 방향측의 살사기에서 살사작업이 행해지도록 개선한 것이다. 먼저, 기관차의 일반적인 구동제어장치를 보면, 도면 제1도에 도시된 바와같이 압축공기 비축탱크(9)가 설치된 메인관로(8)에 경적(13)이나 윈도우와이퍼(14)작동용 파이롯드 관로가 연결됨과 동시, 운전제어 대에 설치된 차체전, 후진 스위치(도시하지 않음)에 의해 각기 작동 개방되는 전, 후진 마그네트밸브(10a)(10b)측으로 연결되었으며, 상기 마그네트밸브(10a)(10b)에서 각기 인출된 전, 후진 제어관로(11a)(11b)가 토오크 컴버터(도시하지 않음) 구동 제어용 역전기 내에 설치된 역전실린더(12)의 양단부에 각각 연결 설치되어 있다.The present invention relates to a salsa direction selection device of a locomotive, and the structure of the salsa device is a side of the vehicle body moving direction by a conversion valve which is operated by a normal locomotive drive control device when the engine driver contacts only a foot valve. The salsa work was improved in salsa. First, as a general driving control apparatus of a locomotive, as shown in FIG. 1, a pilot pipeline for operating a horn 13 or a window wiper 14 in a main pipeline 8 in which a compressed air storage tank 9 is installed. Is connected to the front and rear magnet valves 10a and 10b which are operated and opened by the front and rear switches (not shown) installed at the operation control unit, and are connected to the magnet valves 10a and 10b. The forward and backward control conduits 11a and 11b respectively drawn out from are connected to both ends of the reversing cylinder 12 provided in the torque converter (not shown) drive control relay.

따라서 기관사가 차체를 전진시키고져 전, 후진 스위치를 전진측에 위치시키면, 전진측 마그네트 밸브(10a)가 신호를 받아 개방됨에 따라, 압축공기 비축탱크(9)의 압축공기가 메인관로(8)를 통해 전진 마그네트밸브(10a)-전진 제어관로(11a)-역전실린더(12)로 전달되므로서 차체가 전진 동작을 행하게 되고 후진동작은 후진측 마그네트밸브(10b)가 작동되는 것이다.Therefore, when the driver advances the vehicle body and positions the forward and reverse switches on the forward side, the forward side magnetic valve 10a receives a signal and opens, so that the compressed air of the compressed air storage tank 9 is compressed into the main pipe line 8. Through the forward magnet valve (10a) -forward control pipe (11a) -reverse cylinder (12) to the vehicle body to perform the forward operation and the reverse operation is the reverse side magnet valve (10b) is operated.

그리고, 차체의 바퀴 전, 후방에는 각각 살사기를 설치하여 레일상에 눈, 비등의 이물질이 얹혀 있을때 레일면상에 모래를 뿌려 주므로서, 차륜과 레일 사이의 슬립과 편마모 방지 및 소정의 제동효과를 얻을수 있도록 하고 있는 것이다.In addition, before and after the wheels of the car body, the sprayer is installed respectively, and when the foreign matter such as snow or boiling is placed on the rail, sand is sprayed on the rail surface, thereby preventing slip and uneven wear between the wheel and the rail and obtaining a predetermined braking effect. I'm doing it.

그런데, 종래의 살사장치를 보면, 기관실의 일측에 상기 전, 후방측 살사기를 각기 별도로 제어하기 위한 2개의 조작밸브를 설치해 놓고, 차체의 진행방향(전진 또는 후진)에 따라 기관사가 해당밸브를 선택조작하도록 되어 있어서, 가뜩이나 기관차의 운전시 조작부가 많고 신경이 쓰이는 상태에서 살사조작까지 일일이 확인 조작시켜야 하므로 그 조작이 좌우 번거롭고 불편할 뿐만 아니라, 부주의로 살사조작을 잊게되는 사례가 종종 발생하여 살사장치 본래의 운영 및 기능을 최대로 이용치 못하게 되는 문제점과 함께, 전, 후방 살사기 제어를 위한 2개의 제어장치를 필요로 하므로서 그 장치구성 및 설치가 복잡하고 난해한등의 문제점이 있었다.By the way, according to the conventional salvage, two operation valves for controlling the front and rear salsas are separately provided on one side of the engine room, and the engine driver selects the valves according to the traveling direction (forward or backward) of the vehicle body. Since the operation part of the locomotive is a lot of control parts, and it is necessary to check and operate salsa operation in a state where it is bothered, the operation is cumbersome and inconvenient to the left and right, and inadvertent forgetting salsa operation often occurs. Along with the problem that the operation and function of the maximum use is not possible, there are problems such as complicated and difficult to configure and install the device because it requires two control devices for the front and rear salsa control.

따라서, 본 고안은 종래의 위와같은 문제점을 해결하기 위하여, 별도의 사기 작동제어 장치를 배제하고, 메인관로에서 인출한 살사조작 관로에 푸트밸브와, 구동제어 장치에서 인출된 파이롯드 관로에 의해 출구가 가변 개쇄되는 변환밸브를 차례로설 치한뒤, 상기 변환밸브의 출구측에 각각 전, 후측 살사기 분기조작관로를 연결 설치 하므로서, 기관사는 레일상에 살사조작시 차체의 진행방향에 전혀 구애받지 않고 푸트밸브만 접촉 작동시키면, 해당 진행방향측의 살사기가 작동되어 살사케 되는 것으로서, 이를 첨부된 도면을 따라 상세히 설명하면 다음과 같다.Therefore, in order to solve the above problems, the present invention excludes a separate fraud operation control device, and a foot valve to a salsa operation pipe drawn out from the main pipe line and an outlet by a pilot pipe drawn out from the drive control device. After installing the variable-change valves in order, the front and rear salsa branch operation pipes are connected to the outlet side of the conversion valve, respectively, so that the engineer is completely independent of the direction of travel of the vehicle body during the salsa operation on the rail. If only the foot valve is operated in contact, the salsa of the operation direction side is to be salsa, as described in detail with reference to the accompanying drawings as follows.

즉, 압축공기배축탱크(9)가 설치된 메인관로(8)가 차체 전후진 스위치(도시하지 않음)에 의해 각기 개방작동되는 전, 후진 마그네트밸브(10a)(10b)와 접속되고, 상기 각 마그네트밸브(10a)(10b)로부터 역전기의 역전실린더(12) 사이에 각기 전, 후진 제어 관로(11a)(11b)가 연결설치되었으며, 차륜의 전, 후방 일측에 각기 전, 후방 살사기(6)(7)가 설치된 통상의 것에 있어서, 상기 압축공기 비축탱크(9) 전방측의 메인관로(8)에서 살사조작관로(3)를 인출하면서, 인출된 살사조작관로(3)에 푸트밸브(1)와, 상기 전, 후진 제어관로(11a)(11b)에서 각각 인출된 전, 후진 파이롯드관로(4)(5)에 의해 압축공기의 토출방향이 가변되는 변환밸브(2)를 차례로 연결 설치한뒤, 상기 변환밸브(2)의 양측 배기구(26a)(26b)에 각각 전, 후방 살사기(6)(7)의 분기조작관(61)(71)로 를연 결설치하여서된 것이다.That is, the main pipe line 8, in which the compressed air deflation tank 9 is installed, is connected to the front and rear magnet valves 10a and 10b which are respectively opened and operated by the vehicle body forward and backward switch (not shown), and the respective magnets The reverse control conduits 11a and 11b are connected between the valves 10a and 10b and between the reverse cylinders 12 of the reverse electric machine, respectively, and before and after the wheels, respectively. (7), the foot valve (3) is drawn to the salsa operation pipe line (3) while drawing the salsa operation pipe line (3) from the main pipe line (8) on the front side of the compressed air storage tank (9). 1), and the conversion valve (2) in which the discharge direction of the compressed air is varied by the forward and backward pilot pipe lines (4) and (5) respectively drawn out from the forward and backward control pipe lines (11a) (11b). After the installation, connect the connecting pipes 61 and 71 of the front and rear sprayers 6 and 7 to the exhaust ports 26a and 26b of the conversion valve 2, respectively. It is.

여기에서, 상기 변환밸브(2)의 구성을 보면 도면 제2, 3도에서와 같이, 밸브몸체(21)의 후면에는 푸트밸브(1)를 통과한 압축공기가 유입되는 흡기구(22)와, 그 내부양측으로 좌, 우측분기구(23a)(23b) 및 상기분기구와 관통된 좌, 우측 작동공간(24a)(24b)내에는 분기구 개쇄용 피스틴(25a)(25b)이 각기 슬라이딩 자재토록 설치되었으며, 몸체(21)전면 양측에는 상기 작동공간과 관통되고, 전, 후방살사기(6)(7)의 분기조작관로(61)(71)가 각기 연결될 좌, 우측 배기구(26a)(26b)가 형성됨과 동시, 몸체(21)의 양측으로는 상기 전, 후진 파이롯드관로(4)(5)가 연결 설치되어 피스틴(25a)(25b)을 전진 동작시키기 위한 좌, 우측 압력 공기구(27a)(27b)가 형성된 것이다.Here, the configuration of the conversion valve (2) as shown in Figures 2 and 3, the inlet port 22 through which the compressed air passing through the foot valve (1) flows into the rear of the valve body 21, Branch opening and closing pistines 25a and 25b respectively slide in the left and right branch apparatuses 23a and 23b and the left and right operating spaces 24a and 24b penetrating the branch apparatuses, respectively. The left and right exhaust ports 26a which are installed to be freely and are connected to the operating spaces on both sides of the front surface of the body 21 and to which branch operation channels 61 and 71 of the front and rear sprayers 6 and 7 are connected, respectively. At the same time as the 26b is formed, the front and the reverse pilot pipes 4 and 5 are connected to both sides of the body 21 so that the left and right pressures for the forward movement of the pistine 25a and 25b are operated. Air spheres 27a and 27b are formed.

이상과 같이 구성된 본 고안의 작동상태를 보면 다음과 같다.Looking at the operating state of the present invention configured as described above are as follows.

기관사가 운전제어대에 설치된 전, 후진 선택스위치를 일측방향으로조 작하게 되면, 해당측 마그네트밸브가 개방되면서, 압축공기 비축탱크(9)의 압력공기가 해당 제어관로를 통해 역전실린더(12)측으로 들어갈때, 동일 압력이 당해 파이롯드 관로를 통해 변환밸브(2)의 일측압력공기구로 작용하여, 작동공간내의 피스틴이밀려 전진하면서 해당분기구를 지속적으로 쇄쇄시켜 주므로서, 살사조작관로에서 푸트밸브(1)를 통해 들어온 공기는 피스틴이 막히지 않은 배기구를 통해 당해 살사기로 유입되어 살사 작동케되는것이다. 일예로, 기관사가 차량을 전진시키고져 선택스위치를 전진 위치에 놓게되면, 그 신호가 전진마그네트밸브(10a)에 전달 개방되므로서, 압축공기 비축탱크(9)의 압축공기가 전진 마그네트밸브(10a)-전진제어관로(11a)-역전실린더(12)로 전달되어 차량이 전진되는바, 이때 전진제어관로 (11a)에서 인출된 전진 파이롯드 관로(4)를 통해 동일한 공기압이 변환밸브(2)의 우측 압력 공기구(27b)측에 지속적으로 작용되므로서, 우측 피스턴(25b)은 전진하여 우측문기구(23b)를 차단시킨 상태로 위치함에 따라, 기관사가 푸트밸브(1)를 누르게 되면 살사조작관로)3)를 통해 들어온 압력공기 가변환밸브(2)의 흡입구(22)-좌측분기구(23a)-좌측배기구(26a)-전진분기조작관로(61)-전방살사기(6)로 전달되므로서, 차체가 진행하는 전방살사기(6)가 작동되어 살사케 되는 것이다.When the engineer operates the forward and reverse selector switch installed in the operation control unit in one direction, the corresponding magnet valve is opened, and the pressure air of the compressed air storage tank 9 is reversed through the corresponding control line. As it enters the side, the same pressure acts as a one-side pressure air tool of the conversion valve 2 through the pilot pipe line, and the pistine in the working space is pushed forward to continuously block the corresponding air inlet, while the salsa operation pipeline The air entering through the foot valve (1) is introduced into the salsa through the exhaust vent unblocked pistine to operate salsa. For example, when the engine driver advances the vehicle and the selector switch is in the forward position, the signal is transmitted to the forward magnet valve 10a and opened so that the compressed air of the compressed air storage tank 9 is the forward magnet valve 10a. The forward air conduit 11a and the forward cylinder 12 are transferred to the vehicle, and the same air pressure is transferred through the forward pilot conduit 4 drawn from the forward control conduit 11a. As the right piston 25b moves forward and is positioned in a state in which the right door mechanism 23b is shut off while being continuously acted on the right pressure air port 27b side of the engine, salsa operation is performed when the engineer presses the foot valve 1. To the inlet port 22, the left branch mechanism 23a, the left exhaust port 26a, the forward branch operating pipe line 61, and the front sprayer 6 of the pressure air flow control valve 2, As a result, the front slicing machine (6) that the vehicle body is going to be operated salsa.

또한, 차체의 후진시에는 상기의 역방향으로 작동됨은 자명한 것이다.In addition, it is obvious that the vehicle is operated in the reverse direction when the vehicle body moves backward.

이상과 같이 구성되고 작동되는 본 고안은, 메인관로에서 인출된 살사조작 관로에 푸트밸브(1)와, 전, 후진 구동제어장치에 의해 출구가 가변되는 변환밸브(2)를 설치하므로서, 기관사는 차체의 진행방향에 상관하지 않고 푸트밸브(1)만 터치해 주면 자동적으로 진행방향측의 살사기가 동작하여 레일면상에 모래를 뿌려주는바, 종래와 같이 기관사가 일일이 차체 진행방향측의 작동레버를 선별 작동시키던 방식에 비해 그 조작이 매우 간편하고 수월해 졌으며, 그 작동제어장치가 일원화 되면서 구성 및 설치의 단순화 및 간편화를 꾀할수 있는 특출한 효과가 있는 것이다.The present invention is constructed and operated as described above, by installing the foot valve (1) and the conversion valve (2) whose outlet is varied by the forward and backward drive control device in the salsa operation pipeline drawn out from the main pipeline, When only the foot valve 1 is touched irrespective of the traveling direction of the vehicle body, the salsa on the traveling direction automatically operates to spray sand on the rail surface. Compared to the method of selective operation, the operation is very simple and easy, and as the operation control unit is unified, there is an extraordinary effect to simplify and simplify the configuration and installation.
