본 고안은 운반차 설치용 크레인회동장치에 관한 것으로, 특히 운전자가 유압조작 핸들의 조작으로 작동케된 유압실린더의 피스톤로드 선단에 승강봉을 입설한 안내판을 고정하여 승강봉이 직선상에서 승강되게 하고 그 승강봉의 외면에 형성한 나선홈은 베어링으로 기둥위의 지지관에 설치한 회동판 하부관내의 안내돌기에 끼워져서 승강봉이 승강될때 회동판이 좌, 우 회동과 360도 회전을 자유롭게 함으로 회동작동이 원활하고 유동이 없고 작업에 안전성이 있으며, 또 설치구조는 간단하며 소형차량에도 간단히 설치사용 할 수 있고, 운반차량 운전자가 쉽게 조작할 수 있으므로 특히, 농어촌의 소형운반차에 간단히 설치하여 중량물의 상차, 운반, 하차, 이동 설치등에 유효하게 이용될 수 있도록한 운반차 설치용 크레인회동장치에 관한 것이다.The present invention relates to a crane turning device for installing a vehicle, and in particular, the driver fixes the guide plate in which the lifting rod is placed at the tip of the piston rod of the hydraulic cylinder operated by the operation of the hydraulic operation handle so that the lifting rod is lifted on a straight line. The spiral groove formed on the outer surface of the rod is inserted into the guide projection in the lower tube installed on the support pipe on the column as a bearing, and the rotating plate freely rotates left and right and rotates 360 degrees when the lifting rod is elevated. There is no flow, it is safe to work, and the installation structure is simple, and it can be easily installed and used in small vehicles, and it can be easily operated by the driver of the transport vehicle. The present invention relates to a crane turning device for installing a carriage, which can be effectively used for getting off, moving, and the like.

종래에 산업상 이용되는 각종 화물 및 농산물의 이동 운반, 상차, 하차설비 작업용으로 차량에 장착된 인출식 또는 절곡식 크레인을 많이 이용하고 있다. 그런데 이들 크레인이 회종장치는 회전반 하부에 큰 윔기어와 베벨기어를 연결설치하고, 회전모우터와 감속기등을 이용하여 회동과 정지를 하도록 구성되어 있으나, 그 구조가 복잡하고 차체에 설치장소가 넓게 되므로 큰 차량에 제한적으로 이동될 뿐 농어촌에서 많이 이용되는 소형운반 차량에는 설치 이용되지 못한 폐단이 있고, 또, 좌, 우회동작동이 원활하지 못할 뿐더러 안정성이 부족하여 작업능률이 떨어지는 결함도 있었으므로, 본 고안은 종래 그 같은 결함을 해소하고, 농어촌에서 많이 쓰이는 소형운반차량에 간단히 설치 사용할 수 있고 크레인의 회동작용을 가볍고 원활하게 함으로 작업능률의 향상과 크레인 이용을 다변화 할 수 있도록 착안한 것인데, 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.BACKGROUND ART Conventionally, a pull-out or bendable crane mounted on a vehicle is frequently used for moving, transporting, loading and unloading equipment of various cargoes and agricultural products. By the way, these cranes are designed to connect large wheel gears and bevel gears to the lower part of the turntable, and to rotate and stop by using a rotary motor and a reducer. As it is wider, it is limited to large vehicles, and small transportation vehicles that are frequently used in farming and fishing villages have closed stages that cannot be used. Also, left and right movements are not smooth, and there are also defects that reduce work efficiency due to lack of stability. The present invention is designed to solve such a deficiency and to easily install and use in small transportation vehicles commonly used in farming and fishing villages, and to improve the work efficiency and diversify the use of cranes by lightly and smoothly rotating the crane. When described in detail based on the accompanying drawings as follows.

운반차(1) 화물적재함의 바닥판(2) 전방 일측에 고정판(3)을 고정하고, 그 고정판(3)위에 안내레일(4")을 형성한 기둥(4),(4')과 지지관(5)을 일직선상에 고정하며, 또 기둥(4),(4')안에는 조작핸들(도시하지 않음)로 조작가능한 유압실린더(6)를 설치하여 그의 피스톤로드(6') 선단에 안내판(7)을 고정하여 안내판(7) 양측의 홈(8)이 기둥(4),(4') 내벽에 형상한 안내레일(4")에 끼워져 있게 하고, 또 안내판(7)중앙위에는 나선홈(10)을 가진 승강봉(9)을 안내판(7)과 일체로 고정하여 지지관(5)내에 상하제어링(11),(11')으로 회동가능하게 설치한 회동판(12) 하부관(13)내의 안내돌기(13a),(13a')에 나선홈(10)이 끼워져서 승강봉(9)이 승강작용할때 회동판(12) 하부관(13)내의 안내돌기(13a)(13a')가 나선홈(10)을 타고 회동할 수 있게 구성하였으며, 그 회동판(12) 상면에는 공지의 크레인(14)을 설치하여 된 것이다.Carrier 1 Fixing plate 3 on one side of the bottom plate 2 of the cargo container, and supporting pillars 4, 4 'formed with guide rails 4 "on the fixing plate 3, and supporting The cylinder 5 is fixed in a straight line, and in the pillars 4 and 4 ', a hydraulic cylinder 6 which is operable with an operation handle (not shown) is installed, and a guide plate at the tip of the piston rod 6' is installed. (7) so that the grooves (8) on both sides of the guide plate (7) are fitted into the guide rails (4 ") formed on the inner walls of the columns (4) and (4 '), and a spiral groove on the center of the guide plate (7). The lower plate of the rotating plate 12 having the lifting bar 9 having the upper portion 10 fixed integrally with the guide plate 7 so as to be rotatable in the support pipe 5 by the upper and lower control rings 11 and 11 '. Guide grooves (13a) and (13a) in the lower pipe (13) of the rotating plate (12) when the lifting bar (9) is lifted and fitted with the guide grooves (13a) and (13a ') in the guide protrusions (13). ') Is configured to rotate in the spiral groove (10), the top of the rotating plate 12, the known crane (1) 4) was installed.

도면중 미설명부호 15는 고정판(3)에 연결설치한 인출식 받침대이다. 그리고, 승강봉(9)의 나선홈(10)에는 이에 적당한 구리스와 같은 윤활유를 발라서 회전을 원활히 하도록 하였다.Reference numeral 15 in the drawings is a pull-out pedestal connected to the fixed plate (3). The spiral grooves 10 of the elevating rods 9 are smoothly rotated by lubricating oil such as grease.

이와같이 구성된 본 고안은 회동판(12)위에 설치된 크레인(14)을 적당한 작업길이로 인출한 다음 크레인(14)의회동판(12)을 좌,우 또는 360도 회전시켜서 크레인(14)을 이동사용하게 되는데, 본 고안 회동장치의 작동은 운전자가 도시하지 않은 유압조작 핸들의 조작으로 유압실린더(6)의 피스톤로드(6')의 전, 후진 작용하면 피스톤로드(6')선단에 고정한 안내판(7)은 그의 양측 홈(8)이 기둥(4),(4') 내벽의 안내레일(4')에 끼워져 있으므로 승강봉(9)과 함께 일적선상에서 승강작용을 하게 되고, 또 승강봉(9)외면에 요설한 나선홈(10)은 지지관(5)내에 상하베어링(11),(11')으로 설치된 회동판(12) 하부관(13)내의 안내돌기(13a),(13a')에 끼워져 있으므로승강봉(9)이 승강할때는하부관(13)의 안내돌기(13a),(13a')가 나선홈(10)을 타고 돌게 되므로 회동판(12)위에 설치된 크레인(14)도 좌, 우 또는 360도 회전작용을 하게 된다.The present invention configured as described above allows the crane 14 installed on the rotating plate 12 to be withdrawn to a suitable working length, and then rotates the rotating plate 12 of the crane 14 left, right or 360 degrees to move the crane 14. The operation of the rotation device of the present invention is a guide plate (7) fixed to the end of the piston rod (6 ') when the driver acts forward and backward of the piston rod (6') of the hydraulic cylinder (6) by the operation of the hydraulic operation handle (not shown) Since both grooves 8 are fitted to the guide rails 4 'on the inner walls of the pillars 4 and 4', the elevating action is performed on the ship along with the elevating rods 9, and the elevating rods 9 The spiral grooves 10 arranged on the outer surface are guide protrusions 13a and 13a 'in the lower plate 13 of the rotating plate 12 installed in the support pipe 5 by upper and lower bearings 11 and 11'. Since the guide rods 13a and 13a 'of the lower pipe 13 are turned around the spiral groove 10 when the lifting bar 9 is lifted and lifted, the crane 14 installed on the pivoting plate 12. Left, right, or 360 is the rotating action.

이와같이 본 고안은 유압실린더(6)의 피스톤로드(6')는 유압에 의하여 전, 후진 작용을 하게되고, 또 그 선단에 고정시킨 안내판(7)위의 승강봉(9)이 회동판(12)의 하부관(13)내부를 승강할때는 하부관(13)내의 안내돌기(13a),(13a')는 나선홈(10)을 따라 회전하므로 회동판(12)의 회동작용이 가벼우며, 원활하고, 또 유압으로 잡자주기 때문에 요동이 없으며, 안정성이 있어 작업능률을 향상시킬 수 있는 효과가 있고, 또 이러한 구조는 간단하기 때문에 설치면적이 적어 소형운반차량에도 간단히 바닥판(2)에 고정판(3)을 설치 이용할 수 있어 농어촌의 운반차량에 편리하게 다용도로 이용될 수 있는 효과가 있다.Thus, the present invention is the piston rod (6 ') of the hydraulic cylinder (6) is the forward and backward action by the hydraulic pressure, and the lifting bar (9) on the guide plate (7) fixed to the front end of the rotating plate (12) When the inside of the lower tube 13 is elevated, the guide protrusions 13a and 13a 'in the lower tube 13 rotate along the spiral groove 10 so that the rotation of the rotating plate 12 is light and smooth. In addition, since it is hydraulically stable, there is no fluctuation, and stability has the effect of improving work efficiency. In addition, since the structure is simple, the installation area is small, so that even a small transport vehicle can easily be fixed to the bottom plate (2). 3) can be installed and used, which can be conveniently used for transporting vehicles in farming and fishing villages.
