본 고안은 러핑(luffing)크레인, 타워크레인 및 지브크레인과 같은 각종 크레인의 연장조립식마스트의 단위 마스트에 관한 것으로, 특히 단위마스트의 하단부수평앵글에 안내로울러를 착탈가능하게 부착함으로서 마스트 연장작업시 크레인으로 들어올려진 단위마스트를 마스트연장작업용 케이지내로 손쉽고, 안전하며, 정확하게 이동시킬 수 있는 크레인의 단위마스트에 관한 것이다.The present invention relates to a unit mast of an extended assembly mast of various cranes such as luffing crane, tower crane and jib crane, and in particular, by attaching a detachable guide roller to the lower horizontal angle of the unit mast, It relates to a unit mast of a crane that can easily, safely and accurately move the raised unit mast into a cage for mast extension work.
일반적으로 크레인의 마스트연장작업은 마스트연장작업용 케이지의 유압식 또는 체인블럭식 마스트상승기구를 이용하여 케이지의 위쪽 마스트를 상승시킨 상태에서 상승된 위쪽 마스트와 아래쪽 마스트사이로 단위마스트를 끼워넣은 다음 이들 마스트를 조립하여 연장작업을 마무리하는 것인바, 종래에는 제 5 도와 제 6 도에 도시된 바와 같이 크레인(A)상부를 선회시키는 구동부(B) 아래쪽에 "I"형 빔을 외발보형태로 고정시킨 붐(boom)(50)과, 이 붐(50)상에 활주가능한 고가이동활차(51), (51')와 현수루프(52), (52')를 가진 크래들(cradle)(53)로 이루어진 이동기구(54)를 이용하여 크레인(A)으로 들려올려진 단위마스트(m)를 매달린 상태로 마스트연장 작업용 케이지(C)쪽으로 이동시켜서 마스트연장작업을 실시해왔었기 때문에 마스트연장작업용 케이지(C)의 플랫포옴(D)이 평면에서 바라보았을 때 "ㄷ"자형 작업공간만을 가질 수 밖에 없는 것이므로 작업자의 불필요한 동선의 증가를 초래하여 작업성이 나빴을 뿐 아니라 크래들(53)에 매달린 단위마스트(m)를 마스트연장작업용 케이지(C)쪽으로 잡아당겨주기 위해서는 작업자가 플랫포옴(D)의 핸드레일(E)밖으로 상체를 크게 노출시켜야만 하므로 안전사고를 유발할 우려가 컸었고, 또 크래들(53)에 매달린체 이동시킨 단위마스트(m)를 조립하기 위하여 정확한 조립위치로 내려놓기가 매우 불편한 등의 문제점이 있었다.In general, mast extension work of crane is performed by using hydraulic or chain block mast lift mechanism of the cage for mast extension work, and inserting the unit masts between the raised upper mast and the lower mast while raising the upper mast of the cage. To finish the extension work by assembling, conventionally, as shown in FIG. 5 and FIG. 6, a boom in which the "I" -shaped beam is fixed in a unilateral form under the drive unit B for turning the crane A upper portion. a boom 50 and a cradle 53 having a highly movable pulley 51, 51 ′ and a suspension loop 52, 52 slidable on the boom 50. Mast extension work cage (C) because the mast mast (m) lifted by the crane (A) was moved to the mast extension work cage (C) by using the moving mechanism (54). Ple When the foam (D) is viewed from the plane, it has no choice but to have only a "c" shaped work space, which leads to an unnecessary increase in the worker's movement, resulting in poor workability and a unit mast (m) suspended on the cradle 53. In order to pull toward the mast extension cage (C), the operator had to expose the upper body out of the handrail (E) of the platform (D) so that there was a high risk of causing a safety accident, and also suspended the cradle (53) In order to assemble the unit mast (m) there was a problem such as very uncomfortable to put down to the correct assembly position.
본 고안은 이와 같은 종래의 제반문제점을 해결한 것인바, 본 고안의 목적은 단위마스트자체에 단위마스트를 마스트연장작업용 케이지내로 이동시켜 줄 수 있도록 회전자재되게 측설되는 안내로울러를 단위마스트의 하단부에 착탈가능하게 부착함으로서 단위마스트를 손쉽고, 안전하며, 정확하게 이동시키면서 조립할 수 있는 연장조립용 안내로울러를 가진 크레인의 단위마스트를 제공하는데 있다.The present invention has solved such a conventional problem, the purpose of the present invention is to guide the guide roller which is staked in the rotating material so as to move the unit mast in the cage for the mast extension work to the lower end of the unit mast The detachable attachment provides a unit mast of a crane having an extension assembly guide roller that can be assembled with easy, safe and accurate movement of the unit mast.
이하 본 고안을 예시도면에 의하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail by way of example.
본 고안은 제 1∼4도에 예시된 바와 같이 기둥을 이루는 수직앵글(10)과 이 수직앵글(10)들을 연결하는 상, 하부 수평앵글(11)을 가진 단위마스트(m)에 있어서, 하부수평앵글(11)의 양측에 2개씩의 안내로울러 어셈블리(20)를 부착시켜서 된 것이다.According to the present invention, as illustrated in FIGS. 1 to 4, in the unit mast m having a vertical angle 10 forming a column and upper and lower horizontal angles 11 connecting the vertical angles, The two guide roller assemblies 20 are attached to both sides of the horizontal angle 11.
안내로울러 어셈블리(20)는 회전로울러(21)과 지지핀(22)으로 이루어져 있다.Guide roller assembly 20 is composed of a rotary roller 21 and the support pin (22).
회전로울러(21)는 기차바퀴와 유사한 형태로 한쪽에 플랜지(23)가 형성되어 있으며, 중앙에는 중공부(24)가 형성되어 있다.The rotary roller 21 has a flange 23 formed on one side in a shape similar to a train wheel, and a hollow portion 24 is formed in the center thereof.
지지핀(22)은 칼라(25)를 경계로 하는 큰직경부(26)와 작은직경부(27)으로 나누어져 있고, 큰직경부(26)는 상기 회전로울러(21)의 중공부(24)구경보다 약간 작은 직경을 가진 것으로서 베어링(28)으로 상기 중공부(24)내에서 회전로울러(21)와 조립되어 있으며, 작은직경부(27)는 단위마스트(m)의 하부수평앵글(11)과 보강판(11')에 형성된 조립구멍(12)에 끼웠다 빼낼수 있는 크기의 직경을 가진 것으로서 끝부분에는 압축코일스프링(29)으로 탄지되는 스틸볼(30)로 이루어진 스토퍼(31)가 형성된 것이다.The support pin 22 is divided into a large diameter portion 26 and a small diameter portion 27 bordering the collar 25, and the large diameter portion 26 is the hollow portion 24 of the rotary roller 21. It has a diameter slightly smaller than the diameter and is assembled with the rotary roller 21 in the hollow part 24 as a bearing 28, the small diameter portion 27 is the lower horizontal angle 11 of the unit mast (m) ) And a stopper 31 having a diameter of a size that can be inserted into and removed from the assembling hole 12 formed in the reinforcing plate 11 ', and having a steel ball 30 supported by a compression coil spring 29 at the end thereof. Formed.
도면중 미설명부호 40은 마스트연장작업용 케이지(C)로부터 밖으로 길게 연장된 한쌍의 안내레일, F는 유압식마스트 상승기구, M은 단위마스트(m)들을 조립하여서 된 마스트조립체, G는 안내레일(40)의 지지부재 이다.In the drawings, reference numeral 40 denotes a pair of guide rails extending outward from the mast extension work cage C, F is a hydraulic mast lift mechanism, M is an assembly of masts, and M is a guide rail. 40) is a supporting member.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
본 고안은 제 1, 2 도와 제 4 도에 예시된 바와 같이 단위마스트(m)의 하부수평앵글(11)의 양쪽에 2개씩 모두 4개의 안내로울러 어셈블리(20)가 제 3 도에 구체적으로 예시된 바와 같이 상기 하부수평앵글(11)과 보강판(11')의 조립구멍(12)에 끼웠다 빼낼 수 있도록 착탈식으로 부착된 것이기 때문에 제 1 도에 예시된 바와 같이 안내로울러 어셈블리(20)가 부착된 단위마스트(m)를 크레인(A)으로 들어올려서 제 2 도에 예시된 바와 같이 마스트연장작업용 케이지(C)로 밖으로 길게 연장된 안내레일(40)위에 올려놓고 작업자가 단위마스트(m)를 마스트연장작업용 케이지(C)의 안전한 플랫포옴(D)을 벗어나지 않으면서도 마스트연장작업용 케이지(C)내로 손쉽게 이동시켜 유압식 마스트 상승기구(F)에 의하여 상승되어 상부마스트와, 고정된 하부마스트로 분리되는 마스트조립체의 공간에 위치시키면서 단위마스트(m)를 상기 상, 하부 마스트와 연장되게 조립하는 것이다.In the present invention, as illustrated in FIGS. 1, 2 and 4, four guide roller assemblies 20, two on each side of the lower horizontal angle 11 of the unit mast m, are illustrated specifically in FIG. 3. As shown in FIG. 1, the guide roller assembly 20 is attached to and detached from the lower horizontal angle 11 and the reinforcing plate 11 'so as to be detachably attached. Lift the unit mast (m) with the crane (A) and place it on the guide rail (40) extended outward into the mast extension working cage (C) as illustrated in FIG. Without moving out of the safe platform (D) of the mast extension work cage (C), it is easily moved into the mast extension work cage (C) and is lifted by the hydraulic mast lift mechanism (F) to be separated into the upper mast and the fixed lower mast. mast The unit mast m is assembled with the upper and lower masts while being positioned in the space of the assembly.
이때 본 고안은 제 4 도에 도시된 바와 같이 마스트연장작업용 케이지(C)에 고정된 한쌍의 안내레일(40)을 따라서 좌, 우로 유동됨이 없이 상, 하부마스트사이로 이동하는 것이기 때문에 작업자는 전, 후 위치만을 살펴보면서 연장조립위치로 정확하면서도 신속하게 이동시켜 마스트연장조립작업을 실시할 수 있다.At this time, since the present invention is to move between the upper and lower masts without flowing to the left and right along a pair of guide rails 40 fixed to the mast extension working cage (C) as shown in FIG. After looking at the location, it can be moved to the extended assembly position accurately and quickly to perform mast extension assembly work.
이와 같은 본 고안은 단위마스트(m)에 안내로울러 어셈블리(20)를 별도의 작업도구를 사용하지 않으면서도 착탈시킬 수 있도록 된 것이기 때문에 마스트연장조립후 안내로울러 어셈블리(20)를 연장조립이 완료된 단위마스트로부터 분리해내고, 다른 연장조립대상 단위마스트에 부착시키면서 사용하는 것으로서 본 고안은 마스트연장작업을 보다 손쉽고, 안전하며, 정확하면서도 안전하게 실시할 수 있는 장점이 있다.The present invention is such that the guide roller assembly 20 to the unit mast (m) can be attached and detached without using a separate work tool, so the extension assembly of the guide roller assembly 20 after assembly of the mast is completed. As it is separated from the mast and used while attaching to another unit for extension assembly, the present invention has the advantage that the mast extension work can be performed more easily, safely, and accurately.
