본 고안은 러핑(luffing)크레인, 타워크레인 또는 지브크레인과 같은 크레인의 단위마스트에 관한 것으로서, 특히 단위마스트의 상, 하단부에 연장조립용 블럭을 가진 크레인의 단위마스트에 관한 것이다.The present invention relates to a unit mast of a crane such as luffing crane, tower crane or jib crane, and more particularly, to a unit mast of a crane having an extension assembly block on the upper and lower ends of the unit mast.

종래 크레인의 단위마스트로는 마스트의 상, 하부 모서리밖으로 돌출된 노출식 조립부를 가진 것과 마스트의상, 하부 모서리위에 형성된 은폐식조립부를 가진것등이 알려진 바 있었다.Conventionally, the unit mast of a crane has been known to have an exposed assembly protruding out of the upper and lower edges of the mast and a concealed assembly formed on the upper and lower edges of the mast.

상기 노출식조립부는 조립부내에 체결용 볼트나 핀이 끼워지는 수직관통공을 가진 것으로서 마스트연장작업시 각 마스트조립부의 관통공들이 정확하게 일치되도록 위치를 맞추어주기가 어려웠을 뿐 아니라 볼트나 핀이 마스트의 연장부위에 작용되는 전단하중을 직접적으로 받는 것이기 때문에 충분한 전단응력을 갖도록 해주기 위해서는 볼트나 핀의 굵기를 비교적 크게 설계해주어야만 하므로 조립부자체가 커지게 되고 마스트의 수직앵글밖으로 크게 돌출될 수 밖에 없어 필요에 따라서 마스트에 리프트와 같은 운반수단을 부가설치하기가 어려운 등의 문제점이 있었다.The exposed assembly part has a vertical through hole into which the fastening bolt or pin is inserted into the assembly part, and it is difficult to adjust the position so that the through holes of the mast assembly parts are exactly matched during the mast extension operation. Since it is directly receiving shear load acting on the extension part of, the thickness of bolt or pin must be designed relatively large in order to have sufficient shear stress, so the assembly itself becomes large and protrudes greatly outside the vertical angle of the mast. There was no problem that it is difficult to additionally install a transport means such as a lift to the mast if necessary.

그리고 은폐식조립부는 마스트의 수직앵글로부터 연장되는 돌기형태의 플러그와 이 플러그가 끼워지는 소켓에 각각 수평관통공을 뚫고 플러그와 소켓의 조립시 일치되는 관통구멍에 빗장핀을 끼우며 이 빗장핀의 한쪽 끝부분에는 분할핀을 끼우도록 된 것으로서, 플러그가 빗장핀이 끼워지는 수평관통공을 가공하기 위해서는 비교적 긴 길이를 가져야만 하고, 소켓은 플러그가 끼워졌을때 플러그가 유동되는 것을 방지하기 위해 최소한의 조립틈새만을 가져야만 하기 때문에 마스트의 운반, 설치도중 소켓이 손상될 경우 상기 노출식조립부를 가진 마스트와 마찬가지로 마스트의 연장작업이 어렵게 될 뿐 아니라 빗장핀과 분할핀을 순차적으로 조립해주어야만 하기 때문에 마스트의 연장작업과 해체작업이 번거로운 문제점이 있었고, 또 빗장핀의 헤드가 마스트의 수직앵글밖으로 돌축되는 것이기 때문에 상기 노출식조립부를 가진 마스트와 마찬가지로 필요에 따라서 마스트에 리프트와 같은 운반수단을 부가설치하기가 어려운 등의 문제점이 있었다.The concealed assembly part drills horizontal through-holes in the projection-type plugs extending from the vertical angle of the mast and the sockets in which the plugs are fitted, and inserts the pins in the matching through-holes when assembling the plugs and sockets. One end is fitted with a split pin, the plug must have a relatively long length to machine the horizontal through-hole into which the pin is fitted, and the socket must be kept to a minimum to prevent the plug from flowing when the plug is inserted. If the socket is damaged during the transportation and installation of the mast, as well as the mast with the exposed assembly, it is difficult to extend the mast, and the latch pins and the split pins must be assembled in sequence. Extension work and dismantling work has been troublesome. Since the rod is crushed out of the vertical angle of the mast, there is a problem that it is difficult to additionally install a transportation means such as a lift to the mast as necessary as in the mast having the exposed assembly.

본 고안은 상술한 바와 같은 종래것의 문제점을 해결함과 동시에 높은 하중에 견딜 수 있는 크레인의 단위마스트를 제공하는데 그 목적이 있는 바 이하 상세히 설명하면 다음과 같다.The present invention solves the problems of the prior art as described above and at the same time provide a unit mast of a crane capable of withstanding high load bar is described in detail as follows.

제1도는 본 고안에 사용되는 조립용 블럭(A)(A'), 연결용 핀(B) 및 클립(C)을 표시한 것으로서, 상부의 조립용 블럭(A)은 단위마스트(M)의 하단부에, 그리고 하부의 조립용 블럭(A)은 단위마스트(M)의 상단부에 용접등의 방법으로 고정되어 있는 것이다.1 is a view showing the assembly block (A) (A '), the connecting pin (B) and the clip (C) used in the present invention, the assembly block (A) at the top of the unit mast (M) The lower end portion and the lower assembly block A are fixed to the upper end portion of the unit mast M by welding or the like.

제2도는 본 고안의 단위마스트의 평면도인바 단위마스트(M)의 상단부 4곳에 4개의 조립용 블럭(A')이 각각 순차적으로 90도의 각도로 변위되어 고정되어 있다.2 is a plan view of the unit mast of the present invention, four assembly blocks A 'are respectively fixed to four upper ends of the unit mast M by being sequentially displaced at an angle of 90 degrees.

본 고안에 사용되는 조립용 블럭(A)(A')은 기저부(1)의 상면에 끼움돌기(2)(2')가 일정간격의 틈(3)을 가지고 나란히 돌설되어 있으며, 끼움돌기(2)(2')의 중앙에는 끼움구멍(4)(4')이 수평으로 천공되어 있다.The assembly block (A) (A ') used in the present invention has a fitting protrusion (2) (2') on the upper surface of the base (1) with a gap (3) of a predetermined interval side by side, the fitting protrusion ( 2) In the center of 2 ', fitting holes 4 and 4' are perforated horizontally.

또 한쪽 끼움돌기(2)의 측면에는 걸림턱(5)이 형성되어 있다.In addition, the locking jaw 5 is formed on the side surface of the one fitting projection 2.

본 고안은 조립용 블럭(A)(A')의 기저부(1)가 단위마스트(M)의 상, 하단부에 끼워진체로 고정되어 있으므로, 본 고안을 조립할때에는 제3도에 도시한 바와 같이 끼움돌기(2)(2')를 서로 엇갈리게 맞물리게 한 다음에 끼움구멍(4)(4')을 통하여 핀(B)을 끼워서 고정시킨후 클립 (C)으로 핀(B)을 체결함으로서 본 고안의 단위마스트(M)들을 점차적으로 높게 연장조립하게 되는 것이다.In the present invention, since the base 1 of the assembly block (A) (A ') is fixed to the upper body and the lower end of the unit mast (M), the assembly is carried out as shown in FIG. (2) (2 ') is staggered with each other, and then the pin (B) through the fitting holes (4) (4') to fix the pin (B) by fastening the pin (B) unit of the present invention The masts (M) are gradually extended and assembled.

본 고안은 두개의 끼움돌기(2)(2')를 맞물린 다음에 핀(B)으로 끼워고정시키는 간단한 조립공정만으로 단위마스트를 매우 신속정확하게 연장조립할 수 있으며, 고강도의 끼움돌기(2)(2')로 결합되어 있으므로 큰 하중을 받는 대형 크레인의 마스트에 적합하다.The present invention can be extended and assembled very quickly and accurately by a simple assembly process of engaging two fitting protrusions (2) (2 ') and then fitting them with pins (B), and high strength fitting protrusions (2) (2) ') Is suitable for masts of large cranes under heavy load.

또 본 고안은 단위마스트(M)에 조립용 블럭(A)(A')이 순차적으로 90도 각도로 변위된체로 고정되어 있으므로 핀(B)의 삽입위치도 순차적으로 90도 만큼씩 다른 방향에서 삽입되도록 되어 있다.In addition, the present invention is fixed to the unit mast (M) as the assembly block (A) (A ') is sequentially displaced at an angle of 90 degrees, so the insertion position of the pin (B) is also sequentially by 90 degrees in different directions It is intended to be inserted.

따라서 본 고안으로 연장조립된 크레인의 마스트는 360도 방향에서 굽힘강도가 균일하다.Therefore, the mast of the crane extended by the present invention is uniform in bending strength in the 360 degree direction.
