Description

크레인에 사용되는 후크블록의 구조Hook block structure used for crane

본 발명은 크레인용 후크블록에 관한 것으로, 특히 후크블록을 2폴(Fall)에서 4폴 내지는 4폴에서 2폴로 변환할 때에, 작업이 신속하게 이루어짐은 물론 별도의 인원이 필요하지 않은 크레인에 사용되는 후크블록의 구조에 관한 것이다.The present invention relates to a hook block for a crane, in particular, when converting the hook block from 2 poles (Fall) to 4 poles or 4 poles to 2 poles, the work is made quickly as well as used in a crane that does not require a separate personnel It relates to the structure of the hook block.

일반적으로 크레인은 하물을 들어올려서 상하, 좌우, 전후로 운반하는 기계장치로서 일명 기중기라고도 하는데, 이 크레인이 화물을 들어올릴 때 화물과 직접 접하는 부분이 후크블록인데, 도 6 내지 도 9에 도시된 바와 같이, 후크블럭은 4폴(FALL)에서 2폴(FALL)로 전환시 메인트롤리(Main-Trolley; 100)와 보조트롤리(200)가 연결핀으로 결합된 상태에서 집베이스에 있는 디바이스에 불편한 매뉴얼리락을 실시한 후, 메인후크블럭(101)과 보조후크블럭(201)이 결합된 상태에서 지면으로 내린 후 불편한 수작업을 통하여 양쪽 후크블럭 연결핀(102, 202)을 분해한 후 보조후크블럭(201)을 들어올려 보조트롤리(200)에 결합하면, 메인트롤리(100)가 보조트롤리(200)로부터 분리되어져 2폴(FALL)로 변환되어진다. 또한 작업의 조건이 바뀌어서 2폴에서 4폴로 변환을 할 때에는 상기의 반대 순서로 실시하게 된다.In general, a crane is a machine that lifts a load and carries it up, down, left and right, and also known as a crane. When the crane lifts a cargo, the crane directly contacts the cargo and is a hook block, as shown in FIGS. 6 to 9. Similarly, the hook block is inconvenient manual for the device in the home base with the main trolley (100) and the auxiliary trolley 200 coupled with the connecting pin when switching from 4 pole (FALL) to 2 pole (FALL). After performing the lock, the main hook block 101 and the auxiliary hook block 201 is lowered to the ground in the combined state, and after disassembling both hook block connecting pins 102 and 202 through inconvenient manual work, the auxiliary hook block 201 When lifted up and coupled to the auxiliary trolley 200, the main trolley 100 is separated from the auxiliary trolley 200 and converted into two poles (FALL). In addition, when the work condition is changed and the conversion from 2 pole to 4 pole is performed in the reverse order of the above.

따라서 후크블럭을 2폴에서 4폴, 4폴에서 2폴로 변환할 때에는 작업자가 2인이 1조가 되어 변환해야하므로, 비교적 높은 위치에 있는 작업자가 타워크레인의 밑바닥까지 내려와 작업을 도와야 하기에, 작업자가 불편함을 겪게 됨은 물론 작업능률이 저하되는 문제점이 발생하였다.Therefore, when converting the hook block from 2 poles to 4 poles and from 4 poles to 2 poles, two workers must be converted into one pair, so the worker at a relatively high position must descend to the bottom of the tower crane to help work. As well as experiencing inconveniences, the work efficiency is reduced.

이에 본 발명은 상기와 같은 제반 문제점을 해소 하기 위해 안출된 것으로, 후크블록을 2폴(Fall)에서 4폴 내지는 4폴에서 2폴로 변환할 때에, 중간블럭을 매개로 손쉽게 변환할 수 있음에 따라, 작업이 신속하게 이루어짐은 물론 작업의 효율이 향상되어지는 크레인에 사용되는 후크블록의 구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, when converting the hook block from 2 poles (Fall) to 4 poles or 4 poles to 2 poles, according to the intermediate block can be easily converted as a medium In addition, the object is to provide a structure of the hook block used in the crane that the work is done quickly as well as the efficiency of the work is improved.
