Description

상하차용 안전 승강판Safety platform
본 발명은 상하차용 안전 승강판에 관한 것으로서, 상세하게는 유압식 동력을 사용하지 않고 차량으로부터 전력을 공급받아 와이어 동작으로 승강판을 펼침으로써 경사가 완만한 상태로 놓여지는 새로운 안전 승강판을 제안한다.The present invention relates to a safety lifting plate for up and down loading, and in particular, a new safety lifting plate which is placed in a gentle inclination state by spreading the lifting plate by wire operation by receiving electric power from a vehicle without using hydraulic power. .
농가에서 과수 농사나 밭농사 등 각종 농사를 수행하기 위해서는 인력과 함께 기계 장비의 도움이 꼭 필요하다. 이러한 농업용 기계 장비는 마을 단위로 구매하여 공동 사용하는 경우도 있고, 일부 개별 농가에서 직접 구매하여 사용하는 경우도 있다. 그러나 대부분의 농가에서는 모든 기계 장비를 다 구비하고 있는 것이 현실적으로 어렵기 때문에 필요한 장비를 그 때 그 때 임대하여 사용하는 경우가 허다하다. In order to carry out various kinds of farming, such as fruit farming and field farming, farmers need the help of mechanical equipment. These agricultural machinery may be purchased and shared in village units, or may be purchased directly from some individual farmers. However, in most farms, it is difficult to have all the mechanical equipment, so it is often necessary to rent the necessary equipment at that time.
농기계 임대사업장 또는 농협임대은행에서는 농가에 필요한 각종 농기계들, 예를 들어 파쇄기, 운반차, 관리기, 미니포크레인 등을 임대하고 있는데, 농기계의 운반은 통상 해당 장비를 트럭의 짐칸에 실은 채로 이동하는 경우가 보통이다. 이 경우 트럭에 농기계를 상차하거나 하차시켜야 하는 작업이 요구되는데, 통상 트럭의 짐칸이 지면으로부터 높게 위치해 있어 농기계의 상차 또는 하차 시 별도의 사다리가 필요하다.The agricultural machinery leasing place or the Agricultural Cooperative lease bank leases all kinds of agricultural machinery necessary for farms, such as shredders, trucks, managers, and mini fork cranes.The transport of agricultural machinery is usually carried in a truck's luggage compartment. Is common. In this case, the truck is required to load or unload the farm machinery, usually because the luggage compartment of the truck is located high from the ground, a separate ladder is required when loading or unloading the agricultural machinery.
농기계 상하차에 사용되는 사다리는 보통 알루미늄 재질의 사다리 한 쌍을 트럭 짐칸에 경사지도록 걸어두고 두 사다리에 농기계의 바퀴나 궤도를 지지시킨 채로 농기계를 상차하거나 하차시키게 된다. 그런데, 한 쌍의 사다리를 이용하여 농기계를 상하차시키는 경우 고도의 운전 기술이 필요하며, 농기계의 이동 시 균형을 유지한 채로 이동 속도를 세심하게 제어하지 않는 경우 자칫 상하차 과정에서 트럭 짐칸에 정확히 적재되지 못하거나 충격이 발생될 수 있고, 심한 경우 농기계가 전복되어 목숨을 잃을 수도 있는 대형 사고가 발생하기도 한다. 이와 같이 운반용 트럭에 농기계를 상하차하는 과정에서 빈번한 안전사고가 발생하게 되면, 농기계 임대사용율이 현저히 떨어지게 되어 국가적 재원이 낭비가 되고, 농업 생산성 향상에도 역행하는 결과를 초래한다. A ladder used for loading and unloading agricultural machinery usually hangs a pair of aluminum ladders to be inclined to a truck compartment and loads or unloads agricultural machinery while supporting the wheels or tracks of the agricultural machinery on both ladders. By the way, when loading and unloading farm machinery using a pair of ladders, advanced driving skills are required, and if the speed of movement is not carefully controlled while maintaining the balance of farm machinery, it is not loaded correctly in the truck luggage compartment during loading and unloading. Failure to do so can result in severe accidents and, in severe cases, agricultural machinery can overturn and lead to death. As such, when frequent safety accidents occur in the process of loading and unloading agricultural machinery on a truck, the use rate of agricultural machinery lease is drastically reduced, resulting in a waste of national resources and the improvement of agricultural productivity.
기존의 농기계 상하차용 사다리는 통상의 사다리에 안전 발판만을 구비한 경우가 대부분이어서 안전사고 발생 가능성이 상존하였다. 또한, 개선된 상하차용 사다리의 경우에도 단순히 지지수단이 더 부가되는 정도에 그치기 때문에 안전사고 예방에는 별 효과를 발휘하지 못하였다. 농기계 등을 트럭 짐칸에 적재한 채로 운반하기 위한 승강 수단으로서 기존의 상하차용 사다리를 개선한 실용신안출원 2000-19408호에 따르면, 사다리를 트럭 측면이나 후면에 부착시켜 이동이 편리하고 보관이 간편할 뿐만 아니라 외관을 미려하게 하였다. 또한, 실용신안출원 2004-23532호에 따르면, 상하차용 사다리의 저부에 하방으로 연장될 수 있는 지지수단을 구비하여 안정성을 강화한 바 있다. 한편, 실용신안출원 2013-7143호의 경우 트럭 후방의 적재부에 사다리를 설치하고, 수평적인 사다리를 트럭 후방으로 인출하여 경사지도록 한 사다리의 인출입 장치를 제안한 바 있다.  Conventional agricultural machinery ladders are usually equipped with only safety scaffold on the ladder, so the possibility of a safety accident has always existed. In addition, even in the case of an improved ladder for loading and unloading, since the support means are merely added, the safety accidents were not effective. According to Utility Model Application No. 2000-19408, which upgrades existing ladders for lifting and unloading agricultural machinery, etc., while they are loaded in a truck luggage compartment, the ladders can be attached to the side or rear of the truck for convenient transportation and easy storage. As well as beautiful appearance. In addition, according to Utility Model Application No. 2004-23532, the stability is provided by the support means that can be extended to the bottom of the ladder for loading and unloading. On the other hand, Utility Model Application No. 2013-7143 has proposed a ladder withdrawal device to install a ladder in the loading portion of the rear of the truck, and to draw a horizontal ladder to the rear of the truck to incline.
이와 같은 종래 기술들은 기존의 상하차용 사다리를 일부 변형하여 개선된 효과를 제시하고 있지만, 차량 구조를 변경하거나 지정된 차량에만 설치가 가능한 단점을 해소하지 못하고 있으며, 사다리 설치를 위한 구조변경된 차량이나 유압 펌프, 모터를 장착한 차량에 한하여 설치가 가능한 한계점이 있고, 사다리 설치 시간이 많이 소요되는 등 이용자 측면에서 개선해야할 점들이 많이 존재한다. Such prior arts suggest improved effects by partially modifying the existing ladders for loading and unloading, but do not solve the disadvantages of changing the vehicle structure or installing them only in designated vehicles, and restructured vehicles or hydraulic pumps for ladder installation. In addition, there are limitations that can be installed only for vehicles equipped with motors, and there are many points to be improved in terms of users, such as a long time for installing a ladder.

이와 같은 기술적 특징 및 그에 따른 효과에 대하여 도면을 참조하며 바람직한 실시예를 통하여 보다 상세하게 설명한다. Such technical features and the effects thereof will be described in more detail with reference to the accompanying drawings and preferred embodiments.
도 1을 참조하면, 본 발명에 따른 안전 승강판(100)은 상판(110), 중판(120), 하판(130) 및 와이어(140), 그리고 와이어의 감김 및 풀림 수단(150)을 포함한다. Referring to FIG. 1, the safety elevating plate 100 according to the present invention includes an upper plate 110, a middle plate 120, a lower plate 130 and a wire 140, and winding and unwinding means 150 of the wire. .
상판(110)은 트럭 등의 운송차량 후방의 적재함에 안착되도록 평판 또는 프레임으로 형성된다. 상판에는 와이어(140) 및 와이어의 감김과 풀림 수단(150)이 구비된다. 와이어는 와이어의 감김과 풀림 수단에 감겨진 채로 와인딩 또는 언와인딩되면서 상판과 중판의 거리(내지 각도)를 조절한다. The upper plate 110 is formed of a flat plate or a frame so as to be seated in a loading box behind a transport vehicle such as a truck. The upper plate is provided with a wire 140 and the winding and unwinding means 150 of the wire. The wire is wound or wound around the winding and unwinding means of the wire to adjust the distance (or angle) between the top plate and the midplate.
중판(120)은 상기 상판의 일단에 회동 가능하도록 결합되며, 평판 또는 프레임으로 형성될 수 있다. 중판의 일측에는 상기 와이어가 연결되어 와이어의 감김 및 풀림 동작에 따라 중판이 상판에 대해 경사도가 변화된다. 하판(130)은 중판의 타단(상판과 결합되는 중판의 일단 반대편)에 회동 가능하도록 결합된다. 이와 같이 중판을 중심으로 상판과 하판이 각각 중판의 양단에 회동 가능하게 연결됨으로써 승강판이 접혀진 상태로 보관될 수도 있고 필요에 따라 길게 펼쳐질 수 있게 된다. The middle plate 120 is rotatably coupled to one end of the upper plate and may be formed of a flat plate or a frame. The wire is connected to one side of the middle plate so that the inclination of the middle plate with respect to the upper plate changes according to the winding and unwinding operation of the wire. The lower plate 130 is rotatably coupled to the other end of the middle plate (an opposite side of the middle plate coupled with the upper plate). As such, the upper plate and the lower plate are pivotally connected to both ends of the middle plate, respectively, so that the lifting plate can be stored in a folded state or can be unfolded as needed.
상기 와이어의 감김과 풀림 수단(150)은 와이어의 감김과 풀림 동작에 필요한 전원을 차량의 배터리로부터 공급받기 위한 전원케이블(160)을 포함하고 있고, 전원케이블의 끝에는 접속 단자(162)가 연결될 수 있다.The winding and unwinding means of the wire 150 includes a power cable 160 for receiving the power required for the winding and unwinding of the wire from the battery of the vehicle, and the connection terminal 162 may be connected to the end of the power cable. have.
상기 상판의 일측에는 도 2에 도시한 바와 같이 인장 체인(170)의 일단이 고정된다. 인장 체인은 상기 중판을 거쳐 상기 하판에 타단이 고정된다. 인장 체인은 중판이 상판에 대하여 경사도가 변화될 때 하판에 인장력을 가함으로써 중판과 하판이 펼쳐지도록 한다. 상기 중판과 하판이 만나는 지점에서 하판의 끝단에는 상기 인장 체인의 이동을 안내하는 체인 가이드(132)가 마련되어 있다. 이 가이드에 의하여 인장 체인이 중판과 하판의 펼쳐지는 동작에도 안전하게 하판을 지지할 수 있고, 하판과 중판이 펼쳐진 후 일자로 평행하게 유지될 수 있다. One end of the tension chain 170 is fixed to one side of the upper plate as shown in FIG. The tension chain is fixed at the other end to the lower plate via the middle plate. The tension chain causes the middle plate and the lower plate to unfold by applying a tension force to the lower plate when the middle plate is inclined with respect to the upper plate. A chain guide 132 is provided at the end of the lower plate at the point where the middle plate and the lower plate meet to guide the movement of the tension chain. By this guide, the tension chain can securely support the lower plate even when the middle plate and the lower plate are unfolded, and can be kept parallel to the date after the lower plate and the middle plate are unfolded.
본 발명의 안전 승강판에서 상기 중판과 하판은 와이어의 감김에 의해 도 1에서와 같이 상판에 대해 수직으로 세워진 채로 중판과 하판이 마주보는 제1상태를 유지할 수 있다. 이러한 제1상태는 안전 승강판이 접혀진 상태로서 부피가 최소화되며 이 상태에서는 트럭에 승강판을 적재한 채로 이동이 용이하다. In the safety elevating plate of the present invention, the middle plate and the lower plate can maintain the first state facing the middle plate and the lower plate while standing perpendicular to the upper plate as shown in Figure 1 by the winding of the wire. This first state is a state in which the safety lifting plate is folded, the volume is minimized, in this state it is easy to move while loading the lifting plate on the truck.
와이어의 풀림에 의해 후술하는 바와 같이 상판에 대해 경사진 채로 중판과 하판이 나란하게 펼쳐지는 제2상태로 변화되는데, 와이어 풀림 동작으로 제1상태에서 상판에 근접하여 세워진 상태의 중판이 자중에 의해 하방으로 경사지도록 펼치는 작용을 한다. 따라서, 본 발명의 안전 승강판에서 와이어의 감김 및 풀림 동작의 적절한 제어가 매우 중요하다. Due to the loosening of the wire, the middle plate and the lower plate are unfolded side by side while being inclined with respect to the upper plate as described later. It acts to unfold downward to incline. Therefore, proper control of the winding and unwinding operation of the wire in the safety lifting plate of the present invention is very important.
도 3은 안전 승강판의 와이어 감김 및 풀림 수단을 보인 사시도로서, 감김 및 풀림 수단(150)을 상판에 연결된 지지대(112)에 결합하여 고정시킬 수 있다. 상기 와이어의 감김 및 풀림 수단은 전기 모터를 구비한 윈치(winch)를 이용할 수 있다. 윈치에 연결된 케이블을 차량의 배터리에 연결함으로써 어느 장소에서도 와이어의 감김 및 풀림 동작을 진행할 수 있으며, 승강판을 적재함에 적재시키거나 지면에 대해 설치할 수 있다.3 is a perspective view showing the wire winding and unwinding means of the safety lifting plate, the winding and unwinding means 150 can be fixed to the support 112 connected to the top plate. The winding and unwinding means of the wire may use a winch with an electric motor. By connecting the cable connected to the winch to the battery of the vehicle, the winding and unwinding of the wire can be performed at any place, and the lifting plate can be loaded into the loading box or installed on the ground.
와이어와 더불어 본 발명의 안전 승강판에 있어서 중판과 하판의 펼침 작용을 담당하는 인장 체인이 매우 중요하다. 인장 체인은 일정한 길이를 유지하면서 상판의 일측으로부터 (중판을 거쳐) 하판에 연결된다. 와이어의 풀림 작용을 통해 중판이 아래로 경사지면서 이동하게 되면, 하판에 연결된 인장 체인이 하판에 인장력을 가하게 됨으로써 하판이 중판에 대해 펼쳐지게 된다. 도 4는 안전 승강판의 인장 체인(170)을 보인 사시도로서, 상판으로부터 하판에 인장력을 가하는 인장 체인의 길이에 따라 중판과 하판이 펼쳐진 후 중판과 하판 사이의 최종 각도가 결정된다. 인장 체인의 길이는 하판이 중판에 대해 펼쳐져 최종적으로는 중판과 하판이 일직선을 유지하도록 조정된다. 이를 위하여, 인장 체인의 일단이 고정된 상판에는 턴버클(도 6의 172 참조) 등의 길이 조절 수단이 부가되는 것이 바람직하다. 또한, 전술한 체인 가이드(132)와 함께 도 4에 도시된 바와 같이 체인 안내 고리 등도 인장 체인이 위치를 벗어나지 않고 정확하게 하판에 인장력을 가하는데 도움이 된다. In addition to the wire, in the safety lifting plate of the present invention, the tension chain which is responsible for the unfolding action of the middle plate and the lower plate is very important. The tension chain is connected to the lower plate (via the middle plate) from one side of the upper plate while maintaining a constant length. When the middle plate moves downwardly inclined through the loosening action of the wire, the tension chain connected to the lower plate exerts a tensile force on the lower plate so that the lower plate is unfolded with respect to the middle plate. 4 is a perspective view showing the tension chain 170 of the safety lifting plate, the final angle between the middle plate and the lower plate is determined after the middle plate and the lower plate is unfolded according to the length of the tension chain to apply a tensile force from the upper plate to the lower plate. The length of the tension chain is adjusted so that the lower plate unfolds with respect to the middle plate and finally the middle plate and the lower plate keep in line. To this end, it is preferable that a length adjusting means such as a turnbuckle (see 172 of FIG. 6) be added to the top plate to which one end of the tension chain is fixed. In addition, as shown in FIG. 4 together with the chain guide 132 described above, a chain guide ring or the like also helps the tension chain to apply tension to the lower plate accurately without leaving the position.
본 발명의 안전 승강판은 와이어의 감김에 의해 상판에 대해 수직으로 세워진 채로 중판과 하판이 마주보는 제1상태로부터, 와이어의 풀림에 의해 상판에 대해 경사진 채로 중판과 하판이 나란하게 펼쳐지는 제2상태로 변화된다. The safety elevating plate of the present invention is made from the first state in which the middle plate and the lower plate facing perpendicular to the upper plate by the winding of the wire, the middle plate and the lower plate unfolded side by side while being inclined with respect to the upper plate by the loosening of the wire. It changes to two states.
도 5는 안전 승강판의 구동 모습을 보인 모식도로서, 제1상태에서 제2상태로 변화되는 모습을 보이고 있다. 와이어가 풀리면서 중판은 상판에 대해 마주보던 상태에서 점차적으로 경사도가 커지면서 펼쳐지게 되고, 하판도 인장 체인의 인장력을 받으면서 중판에 대해 경사도가 커지면서 펼쳐지게 된다. 5 is a schematic view showing a driving state of the safety lifting plate, showing a state of changing from the first state to the second state. As the wire is unwound, the middle plate is unfolded by gradually increasing its inclination while facing the upper plate, and the lower plate is unfolded by increasing its inclination with respect to the middle plate under tension of the tension chain.
그 결과, 최종적으로 도 6에 도시한 바와 같이 안전 승강판이 펼쳐진 상태로 변화된다. 이러한 제2상태에서 중판과 하판은 일자로 평행하게 유지되면서 지면에 대해 경사를 가진 지지면을 제공하게 된다. 이와 같은 제2상태는 차량 정지 시 승강판이 트럭 후방의 지면에 펼쳐지게 되며, 차륜이나 궤도를 구비한 농기계 등이 승강판을 따라 트럭의 적재함으로 이동할 수 있다. 이와 같이, 본 발명의 안전 승강판은 와이어 풀림 작용을 통해 세워진 중판이 자중에 의해 하방으로 경사지도록 펼쳐지도록 함으로써 농기계 등의 상차 및 하차를 위한 낮은 경사면을 제공하게 된다. As a result, as shown in FIG. 6, the safety lifting plate is changed into the unfolded state. In this second state, the middle plate and the lower plate are provided parallel to the ground to provide a support surface with an inclination with respect to the ground. In this second state, when the vehicle is stopped, the lifting plate is spread out on the ground behind the truck, and a farm machine having wheels or tracks can move to the loading box of the truck along the lifting plate. In this way, the safety lifting plate of the present invention is to provide a low inclined surface for loading and unloading of agricultural machinery, such as by unfolding so that the middle plate erected through the wire loosening action to be inclined downward by its own weight.
본 발명의 안전 승강판에서 상기 상판은 양 측부에 차량 적재함과 고정하기 위한 고정와이어 연결부(115)가 마련되어 있고, 예를 들어 자동바 등의 연결수단을 이용하여 상판과 차량 적재함을 연결하여 고정시킬 수 있다. 따라서 트럭의 크기나 적재함 사이즈에 상관없이 본 발명의 승강판을 차량 후방에 고정할 수 있는 장점이 있다. 또한, 1톤 트럭의 경우에는 2 ~ 3 분 정도의 짧은 시간 내에 승강판의 이동이나 탈부착이 가능하게 된다.In the safety elevating plate of the present invention, the upper plate is provided with fixing wire connecting portion 115 for fixing the vehicle loading box and both sides, for example, by connecting the upper plate and the vehicle loading box using a connecting means such as an automatic bar. Can be. Therefore, there is an advantage that can be fixed to the rear of the vehicle lifting plate of the present invention regardless of the size of the truck or the size of the loading box. In addition, in the case of a one-ton truck, the lifting plate can be moved or removed in a short time of about 2 to 3 minutes.
또한, 상기 중판과 하판 사이에는 지지기둥(180)이 개재되어 있는데, 와이어의 풀림에 의해 상판에 대해 경사진 채로 중판과 하판이 나란하게 펼쳐지는 제2상태로 변화되면 상기 지지기둥은 지면을 지지하면서 수직으로 세워지게 된다. 지지기둥은 고하중의 농기계를 빈번하게 상하차시키는 경우 승강판이 변형되는 것을 방지할 수 있다. In addition, a support pillar 180 is interposed between the middle plate and the lower plate. When the middle plate and the lower plate are changed to a second state in which the middle plate and the lower plate are laid out side by side while being inclined with respect to the upper plate by loosening the wire, the support pillar supports the ground. While standing vertically. The support column can prevent the lifting plate from being deformed when the heavy machinery is frequently loaded and unloaded.
본 발명에 따라 실제 제작된 안전 승강판의 동작을 도 7 내지 12에 나타내었다. 최초 트럭 적재함에 접혀진 상태로 승강판이 설치되어 있고 이 상태로 원하는 장소로 자유롭게 이동이 가능하다(도 7). 농기계 등을 상차하기 위해 트럭을 정차시킨 후 승강판을 동작시킨다. 상판은 트럭 후방의 적재함에 고정된 채로, 와이어의 풀림에 의해 중판과 하판이 경사가 변화되면서 지면에 펼쳐지게 된다(도 8 ~ 10). 이후, 상차하려는 농기계가 하판과 중판 상면을 지지면으로 하여 트럭에 상차된다(도 11 및 12). 중판과 하판의 상면이 넓고, 지면과 트럭 적재함 상면 사이의 경사도가 상대적으로 낮기 때문에 하중이 큰 농기계의 경우에도 쉽게 트럭 적재함으로 이동이 가능하다. 중판과 하판 사이에는 사진에 나타난 바와 같이 펼쳐지거나 접혀지는 과정에서 충격을 흡수하기 위해 쇼크 업소버가 부가될 수도 있다.7 to 12 show the operation of the safety lifting plate actually manufactured according to the present invention. The lifting plate is installed in a folded state of the first truck loading box and can move freely to a desired place in this state (FIG. 7). Stop the truck to load the agricultural machinery, etc. and operate the lifting plate. While the upper plate is fixed to the loading box in the rear of the truck, the middle plate and the lower plate is unfolded on the ground by changing the inclination by the loosening of the wire (Figs. 8 to 10). Thereafter, the agricultural machinery to be loaded is loaded onto the truck with the lower plate and the middle plate upper surfaces as the supporting surfaces (FIGS. 11 and 12). Since the upper surface of the middle plate and the lower plate is wide, and the inclination between the ground and the upper surface of the truck loading box is relatively low, even a heavy load agricultural machine can be easily moved to the truck loading box. A shock absorber may be added between the middle plate and the lower plate to absorb shocks in the process of being unfolded or folded as shown in the photograph.
이러한 본 발명의 안전 승강판을 이용함으로써 농기계상하차시 일어날 수 있는 사고를 크게 줄일 수 있으며 소, 말과 같은 가축도 다치지 않고 안전하게 트럭으로 이동시킬 수 있을 것이다. 특히 트럭 적재함에 탈부착이 간단하기 때문에 임대용으로 활용하는데 매우 유리하다.By using the safety lifting plate of the present invention can greatly reduce the accidents that can occur when loading and unloading farm machinery, and livestock such as cattle, horses can be safely moved to the truck. In particular, since it is easy to attach and detach the truck loading box, it is very advantageous to use for rental.
