Description

트랜스퍼 크레인의 스프레더Spreader of Transfer Crane

(기술분야)(Technology)

본 고안은 컨테이너 하역 설비인 트랜스퍼 크레인(transfer crane)의 스프레더(spreader)에 관한 것이며, 특히 시브블록(sheave block)이 스프레더와 분리 및 조립될 수 있는 시브블록 분리형 스프레더에 관한 것이다.The present invention relates to a spreader of a transfer crane, which is a container unloading facility, and more particularly, to a sheave block split spreader in which a sheave block can be separated and assembled with a spreader.

(배경기술)(Background)

제1도 및 제2도에 도시된 바와 같이, 종래의 스프레더(2)는 시브블록(5)이 스프레더(2)에 용접으로 고정되어 있기 때문에, 스프레더(2)의 수리 또는 교환을 위하여 트랜스퍼 크레인(1)으로부터 스프레더(2)을 분리하여야 할 경우에는, 트랜스퍼 크레인(1)의 스프레더(2)에 설치되어 있는 로프(3)를 풀어서 분리하지 않으면 안되었다.As shown in FIG. 1 and FIG. 2, the conventional spreader 2 has a transfer crane for repair or replacement of the spreader 2 since the sheave block 5 is fixed to the spreader 2 by welding. When the spreader 2 had to be separated from (1), the rope 3 attached to the spreader 2 of the transfer crane 1 had to be loosened and separated.

조립시에는 로프(3)를 다시 트랜스퍼 크레인(1)과 스프레더(2) 사이에 설치하여야 하며, 상당한 중량과 길이를 가지는 로프를 재조립하는 것이 매우 번거로운 일이었다.When assembling, the rope 3 must be installed again between the transfer crane 1 and the spreader 2, and it was very cumbersome to reassemble the rope having a considerable weight and length.

이와 같이 종래의 스프레더는 스프레더의 분리 및 조립 작업의 어려움으로 인하여, 항만하역설비의 최대의 관심사인 작업시간효율을 급격히 감소시키는 원인으로 작용하였다.As described above, the conventional spreader has been a cause of drastic reduction of the work time efficiency, which is the greatest concern of the port unloading facility due to the difficulty of separating and assembling the spreader.

본 고안은 이러한 종래의 스프레더가 지니고 있는 문제점을 해결하기 위하여 고안된 것으로서, 스프레더의 정비나 교환을 위해 트랜스퍼 크레인으로부터 스프레더를 분리 및 조립할 때, 로프를 트랜스퍼 크레인과 스프레더 사이에서 풀거나 다시 걸어야 하는 불편을 없애고자 하는 것이다.The present invention is designed to solve the problems of the conventional spreader, and when the detacher is assembled and detached from the transfer crane for maintenance or replacement of the spreader, it is necessary to loosen or re-route the rope between the transfer crane and the spreader. It is to be eliminated.

본 고안에 따른 트랜스퍼 크레인의 스프레더는, 스프레더(2)와 시브블록(5)을 분리 가능하게 형성한 것을 그 특징으로 하며, 먼저 제3도 내지 제5도를 참조하여 제1실시예에 대해 설명한다. 도시된 바와 같이, 본 실시예의 시브블록 분리형 스프레더는, 스프레더(2)에 형성된 홀(10)과, 시브블록(5)에 설치되며 레버(12)와 연결바(13) 및 감금수단(11)으로 구성된 연결수단을 포함하고 있다.The spreader of the transfer crane according to the present invention is characterized in that the spreader 2 and the sheave block 5 are formed to be separable. First, the first embodiment will be described with reference to FIGS. 3 to 5. do. As shown, the sieve block separate spreader of this embodiment is provided in the hole 10 formed in the spreader 2, the sieve block 5, the lever 12, the connecting bar 13 and the confinement means 11 It comprises a connection means consisting of.

즉, 스프레더(2)의 상부에는 홀(10)이 형성되어 있고, 로프(3)가 감기는 시브(6)을 지지하는 시브블록(5)의 하부에는, 90˚로 회전할 수 있고 양쪽으로 돌기부가 형성되어 있어서 스프레더(2)의 홀(10)에 삽입되어 잠기고 풀리는 잠금수단(11)이 설치되어 있다. 감금수단(11)에는 이를 90˚회전시키기 위한 연결바(13)가 부착되어 있고, 연결바(13)의 말단에는 레버(12)가 연결되어 있다.That is, the hole 10 is formed in the upper part of the spreader 2, and the lower part of the sheave block 5 which supports the sheave 6 to which the rope 3 is wound can rotate by 90 degrees, and to both sides The protrusion part is formed, and the locking means 11 which is inserted in the hole 10 of the spreader 2, and locks and unwinds is provided. The confinement means 11 is attached to the connecting bar 13 for rotating it 90 degrees, the lever 12 is connected to the end of the connecting bar (13).

시브블록(5)과 스프레더(2)를 조립할 때에는, 스프레더(2)에 형성된 홀(10)에 잠금수단(11)을 삽입하여 레버(12)를 작동하면, 레버(12)에 고정된 연결바(13)가 좌우로 이동하고, 이에 따라 잠금수단(11)이 90˚회전하여 스프레더(2)와 시브블록(5)이 결합하게 한다. 이때 홀(10)과 감금수단(11)은 서로 직각방향으로 교차하여 서로 이탈되지 않게 된다.When assembling the sheave block 5 and the spreader 2, when the locking means 11 is inserted into the hole 10 formed in the spreader 2 to operate the lever 12, the connecting bar fixed to the lever 12 is fixed. 13 is moved to the left and right, thereby locking means 11 is rotated 90 ° to allow the spreader 2 and the sieve block 5 to be coupled. At this time, the hole 10 and the confinement means 11 cross each other at right angles so as not to be separated from each other.

시브블록(5)과 스프레더(2)를 분리할 때에는, 레버(12)를 좌우로 움직여 잠금수단(11)을 90˚ 회전시키면, 홀(10)과 잠금수단(11)의 방향이 동일하게 되어 스프레더(2)가 시브블록(5)으로부터 쉽게 분리된다.When the sieve block 5 and the spreader 2 are separated, the lever 12 is moved left and right to rotate the locking means 11 by 90 °, so that the direction of the hole 10 and the locking means 11 becomes the same. The spreader 2 is easily separated from the sheave block 5.

다음에 제6도 내지 제8도를 참조하여 본 고안의 제2실시예를 설명한다. 도시된 바와 같이, 시브(6)를 지지하는 시브블록(5)은 스프레더(2)의 안내부(8)에 의해 안내되어 스프레더(2)에 결합되어 있으며(제6도 참조), 시브블록(5)은 스프레더(2)에 2개의 핀(7)으로 결합되어 있다(제7도 참조). 시브블록(5)의 양쪽 시브(6)의 하부에는 핀(7)을 결합하기 위한 핀구멍(9)이 각각 형성되어 있다.(제8도 참조).Next, a second embodiment of the present invention will be described with reference to FIGS. As shown, the sheave block 5 supporting the sheave 6 is guided by the guide 8 of the spreader 2 and is coupled to the spreader 2 (see also FIG. 6), 5) is coupled to the spreader 2 by two pins 7 (see FIG. 7). Fin holes 9 for engaging the pins 7 are formed in the lower portions of both sheaves 6 of the sheave block 5 (see FIG. 8).

이와 같은 제2실시예의 구성에 따라 시브블록(5)과 스프레더(2)는 용이하게 조립 및 분리할 수 있다.According to the configuration of the second embodiment, the sheave block 5 and the spreader 2 can be easily assembled and separated.

제9도와 제10도를 참조하여 본 고안의 제3실시예를 설명한다. 본 실시예는 전술한 제2실시예와 동일한 핀결합을 채용하되, 다만 하나의 핀구멍만을 형성하여 하나의 핀(7')만으로 시브블록(5)과 스프레더(2)를 조립 및 분리하도록 한 것이다. 도시된 바와 같이, 시브블록(5)의 하부에는 하나의 핀구멍(9')만이 형성되어 있고, 여기에 하나의 핀(7')으로 시브블록(5)과 스프레더(2)를 조립 및 분리한다.A third embodiment of the present invention will be described with reference to FIGS. 9 and 10. This embodiment adopts the same pin coupling as the second embodiment described above, but only one pin hole is formed to assemble and separate the sheave block 5 and the spreader 2 with only one pin 7 '. will be. As shown, only one pin hole 9 'is formed at the bottom of the sieve block 5, and assembling and separating the sheave block 5 and the spreader 2 with one pin 7'. do.

이와 같이 제2실시예와 제3실시예에서는, 핀(7,7')을 시브블록(5)의 핀구멍(9,9')에 결합하므로써 스프레더(2)를 시브블록(5)에 고정하고, 핀(7,7')을 시브블록(5)의 핀구멍(9,9')에서 제거하므로써 스프레더(2)를 시브블록(5)으로부터 분리한다. 이때 시브블록(5)은 트랜스퍼 크레인(1)에 로프(3)와 함께 매달려 있으므로 스프레더(2)만 분리된다. 또한 시브블록(5)과 스프레더(2)를 조립할 때에는 시브블록(5)이 안내부(8)에 의해 안내되어 핀(7,7')을 용이하게 핀구멍(9,9')에 삽입할 수 있다.Thus, in the second and third embodiments, the spreader 2 is fixed to the sieve block 5 by engaging the pins 7, 7 ′ with the pin holes 9, 9 ′ of the sieve block 5. Then, the spreader 2 is separated from the sieve block 5 by removing the pins 7 and 7 'from the pin holes 9 and 9' of the sieve block 5. At this time, the sheave block 5 is suspended together with the rope 3 to the transfer crane 1, so that only the spreader 2 is separated. In addition, when assembling the sheave block 5 and the spreader 2, the sheave block 5 is guided by the guide portion 8 so that the pins 7 and 7 'can be easily inserted into the pin holes 9 and 9'. Can be.

이상에서 설명한 본 고안에 따른 트랜스퍼 크레인의 스프레더에 의하면, 트랜스퍼 크레인(1)으로부터 스프레더(2)를 분리 및 조립할 때, 시브블록(5)이 로프에 설치된 채로 스프레더(2)만을 분리 및 조립할 수 있으므로, 로프(3)를 트랜스퍼 크레인(1)과 스프레더(2)로부터 풀거나 다시 걸어야 하는 불편이 없으며, 따라서 작업시간을 단축할 수 있는 효과가 있다.According to the spreader of the transfer crane according to the present invention described above, when the spreader 2 is separated and assembled from the transfer crane 1, only the spreader 2 can be separated and assembled with the sheave block 5 installed on the rope. , There is no inconvenience to loosen or re-route the rope 3 from the transfer crane 1 and the spreader 2, and thus there is an effect that can shorten the working time.
