Description
본 발명은 철도 화물을 운송하는 유개화차에 관한 것으로, 더욱 상세하게는 유개화차의 도어 구조 개선을 통해 화물 승,하역시 주변 간섭없이 운송기계의 운용이 자유롭게 행해질 수 있게 하여 화물 운송이 효율적이고, 철도화물 작업의 기계화 발전에 크게 기여할 수 있게 한 것이다.The present invention relates to a railcar for transporting rail freight, and more particularly, by improving the door structure of the railcar, so that the operation of the transport machine can be freely performed without surrounding interference during cargo loading and unloading, cargo transportation is efficient, It has contributed greatly to the mechanized development of rail freight operations.
철도화물 운송을 주목적으로 하는 화차는 적재함의 구조에 따라 무개화차와 유개화차로 구분하고 있다.Wagons, which are primarily intended for rail freight transportation, are classified into flat cars and vans, depending on the structure of the cargo box.
무개화차는 차량의 적재함에 뚜껑이 구비되지 않은 화차를 의미하는 것으로, 먼지나 비에 오염되거나 인화의 우려가 없는 무연탄, 광석, 골재와 같은 원자재 운송에 사용되고 있다.A flat car means a wagon without a lid on a loading box of a vehicle, and is used for transporting raw materials such as anthracite coal, ore, and aggregates, which are not contaminated with dust or rain or ignited.
유개화차는 적재함에 뚜껑이 있는 창고형 화차를 의미하는 것으로, 화물이 노출되는 경우 소손될 염려가 있는 제품화된 화물을 운송에 사용되고 있다.The open car is a warehouse wagon with a lid on the loading box, and is used for transporting a commercialized cargo that may be burned out when the cargo is exposed.
그리고 철도 화차의 경우 화물의 양이 많고 적음에 상관없이 정기적으로 운행되는 것이므로 화물은 매 운행시마다 항상 만재(滿載)된 상태에서 운행하는 것이 효율적이고, 비용도 절감 효과도 기대할 수 있어 경제적인 효과도 크다.In addition, in the case of railway wagons, they are operated regularly regardless of the amount and quantity of cargo, so it is more efficient to operate the cargo in full load at every operation, and it is possible to expect a cost-saving effect. Big.
종래에는 도 1에서와 같이 유개화차(10)는 적재함(11)의 지붕(12)을 제외한 길이가 긴 양쪽 측면부를 도어(15)로 구성하여 상기 도어(15)를 통해 적재함(11)에 화물(20)을 승,하역하도록 구성되어 있다.Conventionally, as shown in FIG. 1, the passer car 10 includes both sides of a long side portion excluding the roof 12 of the storage box 11 as the door 15, and loads the cargo into the storage box 11 through the door 15. 20 is configured to load and unload.
상기한 구성에 있어 유개화차의 도어(15)는 한쪽면에 각각 6개로 분할 형성되는 일반 강재로 제작되고 있어 차량 1량당 1,200kg의 중량을 갖는 도어(15)가 열리고 닫힐 때 이들을 지지, 안내하는 하부측 롤러(17)가 조기에 파손되는 단점이 있다.In the above-described configuration, the doors 15 of the trailer truck are made of general steel which is divided into six pieces on each side, and supports and guides the doors 15 having a weight of 1,200 kg per vehicle when the doors 15 are opened and closed. There is a disadvantage that the lower roller 17 is broken early.
상기한 롤러(17)의 파손은 결국 화물(20)의 적재 및 하역이 적기에 이루어지지 못하여 화물 운송에 커다란 손실을 입게 되는 문제점이 있다.Breakage of the roller 17 has a problem that the loading and unloading of the cargo 20 is not made in a timely manner, causing a great loss in freight transportation.
또한, 화물(20)의 승,하역하기 위해서는 지상 작업장에서 실시하게 되는데 먼저, 화차가 도착하면 지게차로 화물을 적재 및 하역하기 위해서는 그 작업은 화차의 한쪽 방향에서만 실시하게 된다.In addition, the loading and unloading of the cargo 20 is carried out at the ground workshop. First, when the truck arrives, the work is performed only in one direction of the truck to load and unload the cargo with a forklift.
이때는 도 2에 도시한 바와 같이 화물(20)을 이동하기 위한 운송기계가 유개화차(10)의 지붕(12)과의 간섭 즉, 지상 작업장에서 지게차(30) 포크 리프트(32)가 파레트화 된 유니트 화물(20)을 이동하고자 할 때 화물을 올려놓은 포크 리프트(32)의 상단 일부가 지붕(12)에 닿아 그 안쪽으로 진입이 불가능하여 지게차(30)의 운용에 제약을 받게 되었다.In this case, as shown in FIG. 2, the transportation machine for moving the cargo 20 interferes with the roof 12 of the railroad car 10, that is, the forklift 32 is forklift 32 in the ground workshop. When the unit cargo 20 is to be moved, a portion of the upper part of the forklift 32 on which the cargo is placed touches the roof 12 and is impossible to enter therein, thereby limiting the operation of the forklift 30.
이처럼 지게차의 운용이 자유롭지 못하면 승,하역에 어려움이 있을 뿐만 아니라, 많은 시간과 인력이 소요되게 되어 그에 따른 비용 손실은 매우 크다.As such, if the forklift is not free to operate, there is a difficulty in loading and unloading, as well as a lot of time and manpower, resulting in a large cost loss.
이와 같이 종래의 유개화차는 적재함에 화물을 적재할 수 있는 공간은 충분함에도 불구하고 상부측 지붕(12)과의 간섭으로 인해 운송기계의 운용이 자유롭지 못해 특정 위치에는 화물을 싣지 못하고 일부가 빈 공간으로 남게 되는데서 비롯되었던 것이다.Thus, even though the conventional wagon truck has enough space to load the cargo into the loading box, the operation of the transport machine is not free due to the interference with the upper roof 12, and thus the cargo cannot be loaded at a specific location and a part of the space is empty. It is due to the remaining.
상기한 바와 같은 종래 기술의 문제점을 해소하고자 본 발명은, 파레트화 된 유니트 화물의 승,하역 작업시 지게차와 같은 운송기계가 아무런 간섭없이 자유롭게 운용이 가능하게 하여 승,하역 작업이 보다 신속하면서도 비용도 절감되어질 수 있는 유개화차를 제공함을 그 목적으로 하고 있는 것이다.In order to solve the problems of the prior art as described above, the present invention, the loading and unloading operation of the palletized unit cargo can be freely operated without any interference, such as a forklift truck, the loading and unloading operation more quickly and costly The aim is to provide a car that can be reduced.
그리고, 적재함에는 빈 공간이 없이 항상 화물이 만재된 상태로 운행될 수있게하여 철도 화물 운송 효율을 높이는데 또 다른 목적이 있는 것이다.In addition, there is another purpose to increase the efficiency of rail freight transportation by allowing the cargo box to be always loaded with no empty space.
또한, 본 발명은 유개화차의 도어를 일반 강재가 아닌 알루미늄과 같은 경량철재로 구성하여 도어가 경량화되어짐에 따라 그 부분품이 조기에 파손되는 것을 방지함에 그 목적이 있다.In addition, the object of the present invention is to prevent the damage to the parts early as the door becomes lighter by configuring the door of the trailer truck made of light steel, such as aluminum, rather than ordinary steel.

도 3은 본 발명에 따른 유개화차의 구성을 나타낸 일 예시도이고, 도 4는 본 발명에 따른 유개화차에 화물이 승,하역되는 구성을 나타낸 예시도이다.Figure 3 is an exemplary view showing the configuration of the open car according to the present invention, Figure 4 is an exemplary view showing a configuration in which cargo is loaded and unloaded to the open car according to the present invention.
유개화차(10)의 적재함(11) 도어(40)는 화차의 길이가 긴 방향을 기준하여양쪽 측면부에 각각 설치되는 것으로, 상기 측면부의 중앙으로 양분되어 이들 각각이 하나의 도어를 형성하고 있다.The doors 40 of the loading box 11 of the pedestrian truck 10 are respectively installed on both side surfaces of the wagon 10 based on the long direction, and are divided into the centers of the side sections to form one door.
따라서 화차에는 양쪽면에는 각각 2개씩 모두 4개의 도어로 구성되어 있다.Therefore, the wagon is composed of four doors, two on each side.
상기 도어(40)는 화차(10)의 측면부(41) 전체와 상기 측면부(41)의 상측으로 연장되는 지붕(43)의 일부를 포함하는 구성으로 되고, 상기 도어가 닫힌 상태에서는 양쪽 도어(40,401)가 동일 평면을 이루도록 되고, 한쪽 도어(40 도는 401)가 개방되는 경우에는 인접되는 도어(40 또는 401)의 전면으로 슬라이딩되어지며 포개어지도록 구성하였다.The door 40 is configured to include the entire side portion 41 of the wagon 10 and a part of the roof 43 extending upward of the side portion 41, and both doors 40 and 401 in the closed state. ) Is made to be the same plane, and when one door (40 or 401) is opened, it is configured to slide to the front of the adjacent door (40 or 401) and overlap.
각각의 도어는 일반 강재가 아닌 알루미늄과 같은 경량철재로 구성하여 도어의 경량화를 꾀하므로써 그 부분품이 조기에 파손되는 것을 방지할 수 있게 하였다.Each door is made of lightweight steel such as aluminum, not ordinary steel, to reduce the weight of the door to prevent the parts from being damaged early.
적재함(11)의 하부측 양쪽 모서리부위에는 일측방향으로 슬라이딩되는 도어(40)를 안내하는 가이드레일이 설치되어 상기 가이드레일을 따라 이동할 수 있도록 구성되고 있다.At both corners of the lower side of the loading box 11, guide rails for guiding the door 40 sliding in one direction are installed to move along the guide rails.
그리고 적제함(11)의 일측에 설치되는 조종간(50)은 도어개폐장치가 연결되어 상기 조정간(50)의 조작에 따라 도어가 적재함에 고정되거나, 그 고정상태를 해지할 수 있게 하였다.And the control panel 50 is installed on one side of the stacking box 11 is connected to the door opening and closing device is fixed to the storage box in accordance with the operation of the adjustment bar 50, or to be able to release the fixed state.
상기 도어개폐장치는 도어(40)가 일측방향으로 슬라이딩되게 안내하는 가이드를 포함하는 구성으로 되고, 상기 가이드는 상호 절첩이 가능하도록 구성되는 플러그형 사이드문으로 되어 있다.The door opening and closing device is configured to include a guide for guiding the door 40 to slide in one direction, the guide is a plug-type side door configured to be mutually folded.
상기 플러그인형 사이드 문은 상부와 하부에 장축이 설치되고, 이 장축에는 레버가 취부되며, 상기 레버는 도어가 연결되어 상기 장축이 회전시 레버의 힘으로 도어가 열리고, 닫히도록 구성되어 있다.The plug-in side door has a long shaft installed at an upper side and a lower side thereof, and a lever is attached to the long shaft, and the lever is connected to the door so that the door is opened and closed by the force of the lever when the long shaft rotates.
따라서 장축의 회전에 따른 레버의 힘으로 도어가 개방되어질 때 도어는 전면부쪽으로 이동한 후 도어 하부측에 부설되는 롤러가 가이드레일 위에 안착되어질 수 있는 것이다.Accordingly, when the door is opened by the force of the lever according to the rotation of the long axis, the door moves to the front side, and the roller installed on the lower side of the door may be seated on the guide rail.
또한 상기 가이드는 인접되는 도어에 설치되는 가이드홈에 안착되어 개방되어지는 도어를 지지할 수 있게 하여 도어가 이탈되는 것을 방지할 수 있게 하였다.In addition, the guide is able to support the door that is seated in the guide groove is installed in the adjacent door to prevent the door from being separated.
이와 같이 본 발명은 유개화차 도어가 적재함의 측면부와 그 상부측 지붕의 일부를 포함하고 있어 화물을 부리고자 하는 경우에는 작업에 필요한 한쪽 도어측에 살치되는 조종간를 조작하여 열림 위치로 이동시키면 도어는 잠금장치가 해지되게 된다.As such, the present invention includes a side of the cargo truck door and a part of the roof of the upper side of the storage box, and when the cargo is to be loaded, the door is locked by operating the steering wheel disposed on one side of the door required for work. The device will be terminated.
도어의 잠금장치가 해지되면 도어는 레버에 의해 전면부쪽으로 소정의 거리만큼 부상하면서 도어의 하부측에 부설된 롤러가 안내레일에 안착되게 된다.When the lock of the door is released, the door floats toward the front part by a lever, and the roller attached to the lower side of the door is seated on the guide rail.
이 상태에서 도어를 인접되는 도어쪽 방향으로 밀게되면 도어는 안내레일을 따라 인접되는 도어의 상면으로 포개어지듯이 겹쳐지면서 적재함을 서서히 개방하게 된다.When the door is pushed toward the adjacent door in this state, the door overlaps the upper surface of the adjacent door along the guide rail, and gradually opens the stacking box.
따라서 지상 작업장에서 포크 리프트에 화물을 들어 올린 지게차를 적재함 내부로 이동하면서 화물은 2단 적재 및 하역 작업을 자유롭게 수행할 수 있는 것이다.Thus, while moving the forklift that lifts the cargo on the forklift from the ground workshop to the inside of the loading box, the cargo can freely perform two-stage loading and unloading operations.
이처럼 화물을 만재시켰을 경우 년간 900,000ton(60일 ×5ton ×3,000량)에 상당하는 물류 운송비가 절감되는 이점이 있는 것이다.If the cargo is loaded in this way, there is an advantage that the logistics transportation cost equivalent to 900,000 tons per year (60 days x 5ton x 3,000 quantities) is reduced.
이상에서 설명한 바와 같이 본 발명은, 유개화차의 도어의 재질이 일반 강재가 아닌 알루미늄을 소재로 구성함으로써 도어의 경량화가 가능하여 부분품의 파손정도를 대폭 완화시킬 수 있어 사용수명이 연장되는 이점이 있다.As described above, the present invention has the advantage of extending the service life of the door by allowing the door to be lighter by significantly reducing the damage of the parts by using aluminum as the material of the door of the cart. .
또한, 본 발명은 유개화차의 도어 구조 변경으로 파레트화 된 유니트 화물의 승,하역시 아무런 간섭이 없이 지게차를 자유롭게 운용할 수 있게 되어 종래처럼 2단 적재에 어려움이 있었던 위치에도 화물을 적재할 수 있다는 이점이 있다.In addition, the present invention can freely operate the forklift truck without any interference during the loading and unloading of palletized unit cargo by changing the door structure of the trailer truck, it is possible to load the cargo even in the position where the second stage loading was difficult There is an advantage.
따라서 각 화차에는 빈 공간이 없이 만재된 상태로 화물을 적재할 수 있게되어 철도 화물 운송 효율을 높이는데 크게 기여할 수 있게 된다.Therefore, each wagon can be loaded in a loaded state without any empty space, thereby greatly contributing to the improvement of rail freight transportation efficiency.
