Description

갠트리 크레인Gantry crane
본 발명은 갠트리 크레인의 거더 구조를 개선하여 복수 개의 트롤리 및 호이스트가 설치 가능하도록 한 갠트리 크레인에 관한 것으로, 더욱 상세하게 설명하면, 한 쌍의 거더를 구비하되, 상기 거더의 상단 및 하단에 각각 트롤리 및 호이스트를 설치함으로써, 크레인 용량을 향상시킨 갠트리 크레인에 관한 것이다. The present invention relates to a gantry crane that allows a plurality of trolleys and hoists to be installed by improving the girder structure of a gantry crane, and in more detail, a pair of girders is provided, respectively, at the top and bottom of the girder. And a gantry crane having improved crane capacity by installing a hoist.
크레인(crane)은 하물(荷物)을 들어올려서 운반하는 기계장치로서, 일반적으로 크레인은 용도와 형상에 따라 천장 크레인(overhead crane), 지브 크레인(jib crane), 언로더(unloader), 타워 크레인(tower crane), 케이블 크레인(cable crane) 및 갠트리 크레인(gantry crane) 등으로 분류되고, 컨테이너 선박에 컨테이너를 적재하거나 하역하는 데에는 주로 갠트리 크레인이 사용된다.Crane (crane) is a mechanical device that lifts and transports loads. Generally, cranes are overhead cranes, jib cranes, unloaders, and tower cranes depending on the purpose and shape. It is classified into tower crane, cable crane, and gantry crane, and gantry crane is mainly used to load or unload containers on container ships.
상기 갠트리 크레인 혹은 골리앗 크레인(Goliath Crane)은 받침장치(Leg)가 달린 대형 크레인으로 선박 제조와 수리, 항만용 하역 장치이다. The gantry crane or goliath crane (Goliath Crane) is a large crane with a supporting device (Leg), which is a ship manufacturing and repair, loading and unloading device for ports.
상기 갠트리크레인 가운데 대형 갠트리크레인은 주로 조선소에서 선박을 건조하는데 사용되는 것으로, 일반적으로 드라이 도크(dry dock)에서 선박을 건조하는 방법은 조선소의 선체생산 공정에서 철판을 절단하여 소형 블럭단위로 조립된 각각의 블럭을 제작한 후 도크 사이드로 이동시키고, 도크에 설치되어 있는 크레인으로 블럭을 들어 올려도크 내부 정 위치에 탑재하여 선체를 최종 완성시킨다.Among the gantry cranes, large gantry cranes are mainly used for drying ships in shipyards. In general, a method for drying ships in a dry dock is assembled in small block units by cutting steel plates in the shipbuilding process of a shipyard. After making each block, move it to the dock side, lift the block with the crane installed on the dock, mount it in the dock, and complete the hull.
즉, 드라이 도크에 설치되어 있는 크레인의 최대인양 능력에 따라 블럭의 최대 크기와 수량이 결정되는 것으로, 도크 크레인의 인양능력이 크면 선체생산 공정에서 조립블럭도 크게 만들 수 있어 선박의 생산성을 향상시킬 수 있다.In other words, the maximum size and quantity of blocks are determined according to the maximum lifting capacity of the crane installed in the dry dock. If the lifting capacity of the dock crane is large, the assembly block can be made larger in the hull production process to improve the productivity of the ship. Can be.
그러나, 종래의 크레인은, 단일 거더로 구성되므로 크레인의 용량을 증가시키는데 한계가 있다는 문제점이 있었다.However, the conventional crane has a problem that there is a limit to increase the capacity of the crane because it is composed of a single girder.
또한, 이를 보완하고자 제안된 종래의 이중거더 타입의 크레인은 상단 대비 협소한 하단의 단면형상으로, 상단에만 하중이 가해지므로 크레인의 용량을 증가하는데는 한계가 있다는 문제점이 있었다.In addition, the conventional double girder type crane proposed to supplement this has a problem that there is a limit in increasing the capacity of the crane because the load is applied only to the upper end in a narrower cross-sectional shape than the upper end.
그러므로 상기와 같은 종래에서는, 용량이 큰 대형블럭 인양 시, 크레인의 주행방향으로 다수 개의 크레인을 구비하여 대형 블럭을 인양하였으며, 이에 따라 초기비용이 많이 든다는 문제점이 있었다.Therefore, in the related art, when a large block having a large capacity is lifted, a large block is lifted by having a plurality of cranes in the traveling direction of the crane, and accordingly, there is a problem that a large initial cost is required.
또한, 상기 이중거더 타입의 크레인은, 상단 대비 협소한 하단의 단면형상에 의해 하단부에는 보강재가 설치되어지는데, 이때 보강재인 극후판에 요구되는 두께는 제철소에서 제조 가능한 두께를 초과하므로, 상기 극후판은 별도로 분할 제조된 이후 결합되어 사용되나, 이렇게 제조된 극후판은 요구되는 보강력을 지니지 못한다는 문제점이 있었다.In addition, the double girder type crane is provided with a reinforcement material at the lower end by a cross-sectional shape of the lower end compared to the upper end. At this time, the thickness required for the pole plate, which is a reinforcing material, exceeds the thickness that can be manufactured in a steel mill, and thus Is separately used after being separately manufactured, but the pole plate manufactured in this way has a problem that it does not have the required reinforcing power.

본 발명에 따른 갠트리 크레인은, 상기 어퍼트롤리(122)에 결합되는 제1 어퍼호이스트(124) 및 제2 어퍼호이스트(126)와, 제1 및 제2 하부트롤리(162,166)에 결합되는 제1 하부호이스트(164)와 제2 하부호이스트(168)가 좌우 대칭되게 구성되므로, 피이송물의 인양시, 그 하중이 거더에 대해 대칭으로 작용하게 되며, 이에 따라 거더의 변형이 상대적으로 적어서, 정기적으로 상기 거더를 점검 및 보정하는 보정작업의 빈도를 감소시키는 효과가 있다.The gantry crane according to the present invention includes a first upper hoist 124 and a second upper hoist 126 coupled to the upper trolley 122, and a first lower part coupled to the first and second lower trolleys 162 and 166. Since the hoist 164 and the second lower hoist 168 are configured to be symmetrical to the left and right, when lifting the object to be transported, the load acts symmetrically with respect to the girder, and accordingly, the deformation of the girder is relatively small, thereby regularly It has the effect of reducing the frequency of calibration work to check and correct the girders.
또한, 일반적으로 용량이 큰 대형블럭 인양 시, 크레인의 주행방향으로 다수 개의 크레인을 구비하여 대형 블럭을 인양하는데, 본 발명에서는 상기 대형블럭인 피이송물의 하중을 지지하는 하중지지점을 증가시킴으로써, 크레인의 용량을 증대시키는 효과가 있다.In addition, in general, when lifting a large block having a large capacity, the crane is provided with a plurality of cranes in the traveling direction to lift a large block. In the present invention, by increasing the load support point supporting the load of the object to be transported, the large block, the crane It has the effect of increasing the capacity of.
예를 들어, 하나의 하중지지점에 대한 최대하중이 10톤이라 할 때, 종래의 크레인은 최대 3개의 하중지지점을 가지도록 구성되어 있어서, 300톤의 피이송물을 인양하기 위해서는 10대의 크레인을 구비하여야 하였다. For example, when the maximum load for one load support point is 10 tons, the conventional crane is configured to have a maximum of 3 load support points, and 10 cranes are provided to lift 300 tons of transported objects. Had to.
그러나, 본 발명은 거더의 구조를 개선하여, 5개의 하중지지점을 가지므로, 6대의 크레인을 구비하여 300톤의 피이송물을 인양할 수 있게 되는 것이다. However, the present invention is to improve the structure of the girder, because it has five load points, it is possible to lift 300 tons of transported objects with six cranes.
이에 따라, 상기 크레인의 주행부가 주행할 수 있는 횡방향으로의 거리가 확보되므로, 작업이 용이하다는 효과가 있다.Accordingly, since the distance in the transverse direction in which the traveling portion of the crane can travel is secured, there is an effect that the operation is easy.
또한, 같은 하중을 가진 피이송물을 동일한 크레인 수를 구비하여 인양할 때를 가정하면, 본 발명의 크레인은 더 많은 하중지지점을 가지므로, 더욱 더 안정적으로 피이송물을 인양할 수 있어 작업의 안정성이 향상되는 효과가 있다.In addition, assuming the time to lift the object having the same load with the same number of cranes, since the crane of the present invention has more load support points, the object to be transported can be more stably lifted. It has the effect of improving stability.
그리고 크레인의 용량은 탑재할 수 있는 블럭의 최대 중량을 결정하므로, 크레인의 인양능력은 조선소의 생산능력을 결정하는 중요한 요소가 된다.And since the capacity of the crane determines the maximum weight of the block that can be mounted, the lifting capacity of the crane is an important factor in determining the production capacity of the shipyard.
따라서 본 발명의 갠트리 크레인은, 복수 개의 트롤리 및 호이스트를 설치할 수 있도록 거더의 구조를 개선함으로써, 크레인용량을 향상시켜, 설비를 증대시키지 않고도 생산성을 증대시키는 현저한 효과가 있다.Therefore, the gantry crane of the present invention has a remarkable effect of improving the structure of the girder so that a plurality of trolleys and hoists can be installed, thereby improving the crane capacity and increasing productivity without increasing facilities.
