Abstract

Title device having an easily rotative beam to smoothly and exactly decide the position of block was composed of an upper part beam(1) and a lower part beam(6), to which three revolving hanging hooks(16,17,18) were attached. The upper part beam(1), which was hung with freely liftable wire rope at both ends, had a cavity in the middle part and a driving motor(11) so as to rotatably drive for the lower part beam(6) which was freely and rotatively supported with bearing device (9) at the central portion of the upper beam(1).

Description

천정용 크레인의 비임장치Beam device of overhead crane

도면은 어느 것이나 본 발명의 실시예를 도시하는 것으로,All the drawings show an embodiment of the present invention,

제1도는 작용설명도1 is a diagram explaining the operation

제2도는 상세구조를 도시하는 단면도2 is a cross-sectional view showing a detailed structure

제3도는 평면도이며, 도면중 동일 부호는 동일 부분을 도시한다.3 is a plan view, in which like reference numerals denote like parts.

본 발명은 전정용 크레인의 비임장치에 된한 것이다.The present invention is directed to a beam device of a pruning crane.

종래 크레인의 조(吊)비임을 선회자재로 하고 있는 것도 볼 수 있으나, 선회가 원활하지 않던가 파손되기 쉬운 등의 결점이 있었다.It can also be seen that the crane's jaw beam is a turning material in the related art, but the drawback is that the turning is not smooth or breaks easily.

본 발명의 목적은 비임의 선희가 용이하여 블럭을 간단하고 정확하게 위치를 결정할 수 있는 천정용 크레인의 비임장치를 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a beam crane device for a overhead crane that can easily position a block simply by selecting the beam.

즉, 제1도-제3도에 있어서 (1)은 양단을 활차(2)(3)에 감아서건 와이어로우프(4,5)에 의해 매단 수평인 상부 비임으로 상부 비임(1)은 와이어로우프(4),(5)에 의해 수평으로 상하 방향으로 이동됨은 말할나위도 없다. (6)은 거의 중간부에 상기한 상부 비임(1)의 중간 공동부(7)에 삽입되는 원추상의 지지체(8)가 있어서 상부 비임(1)과 항상 평행으로 대향하는 하부 비임으로서 이러한 하부 비임(6)의 지지체(8)의 정부(頂部)는 상기한 상부 비임(1)의 정부에 설치한 축수부(9)와 저부에 설치한 안내(10)에 의해 선회자재로 지지되고 있다. (11)은 상기한 상부 비임(1)의 상면 일정위치에 재치된 하부 비임 선회용 구동모우터로서 이러한 구동모우터(11)는 감속치차장치(12), 중간치차(13) 및 상기한 하부 비임(6)의 지지체(8)에 고정된 링 치차(15)에 치합하는 중간치차(14)를 통해 하부 비임(6)을 180°의 범위에 있어서 자제로 선회하도록 되어 있다. (16)(17)(18')는 상기한 하부 비임(6)의 양단부와 거의 중간부에 각각 장착된 3개의 매달리기용 축으로 이러한 각 축(16)(17)(18')은 상부 비임(1)과 함께 하부 비임(6)이 경사지더라도 항상 수직상태로 유지하도록 핀(18)(19)(20)을 중심으로 하여 양 비임(1)(6)의 길이 방향으로 일정 각도 경사 되도록 됨과 동시에 각 훅(16)(17)(18')자체가 회전이 되도록 되어 있다. 또 비임 양단부의 훅(16,18')은 비임의 긴쪽 방향에 대해 직교하는 방향에도 핀(21,22)을 중심으로 일정각도 경사되도록 되어 있다.That is, in FIGS. 1 to 3, (1) is a top beam horizontally hung by wire ropes 4 and 5 by winding both ends on the pulleys 2 and 3 so that the top beam 1 is wire rope. Needless to say, it is horizontally moved up and down by (4) and (5). (6) is a lower beam which is always confronted in parallel with the upper beam (1) with a conical support (8) inserted into the intermediate cavity (7) of the upper beam (1) described above in the substantially middle part. The top end of the support body 8 of the beam 6 is supported by the turning material by the bearing part 9 provided in the top part of the upper beam 1, and the guide 10 provided in the bottom part. (11) is a lower beam swing drive motor mounted at a predetermined position on the upper surface of the upper beam (1), such a drive motor 11 is a reduction gear 12, the intermediate gear 13 and the lower portion The lower beam 6 is self-controlled in the range of 180 degrees through the intermediate gear 14 that engages the ring gear 15 fixed to the support 8 of the beam 6. (16) (17) (18 ') are three suspension axes mounted respectively at both ends and almost in the middle of the lower beam (6), each of which has a top beam (16) (17) (18'). (1) and the lower beam (6) to be inclined at an angle in the longitudinal direction of both beams (1) and (6) centering around the pins (18), (19) and (20) so that they always remain vertical even if they are inclined. At the same time, the hooks 16, 17 and 18 'themselves are rotated. In addition, the hooks 16 and 18 'at both ends of the beam are inclined at a predetermined angle about the pins 21 and 22 also in a direction perpendicular to the longitudinal direction of the beam.

본 발명에 있어서 천정용 크레인의 비임장치는 상술한 바와같이, 선회하지 않는 상부 비임(1)의 상부에 180°선회하는 하부 비임(6)을 장착한 것이므로 매달린 블럭을 간단히 또 정확하게 위치를 결정할 수 있을뿐 아니라, 블럭을 반전시킬 때는 하부 비임(6)을 180°의 범위내에서 선회시킴으로서 종래와 같이 보조 트로리를 이동시킬 필요가 없으므로 신속한 작업을 할수 있는 우수한 작용효과를 얻을 수가 있는 것이다.In the present invention, since the beam device of the overhead crane is equipped with the lower beam 6 pivoting 180 ° on the upper part of the upper beam 1 that does not turn as described above, the suspended block can be easily and accurately positioned. In addition, when inverting the block, by turning the lower beam 6 within a range of 180 °, it is not necessary to move the auxiliary trolley as in the related art, so that an excellent effect of rapid operation can be obtained.
