도 1 내지 도 5에 도시된 바와 같이, 본 고안은, 견인차량(12)의 차체 상부에 설치된 차체프레임(10) 내에 평행하도록 한 쌍의 레일(20a)(20b)이 설치되고, 이 레일(20a)(20b)에는 구동프레임(30)을 슬라이딩 가능하게 내장하고 있다.As shown in FIGS. 1 to 5, in the present invention, a pair of rails 20a and 20b are installed to be parallel to the body frame 10 provided on the upper body of the tow vehicle 12, and the rails ( The drive frame 30 is slidably incorporated in the 20a and 20b.

상기 구동프레임(30)의 상부에는 붐대인출장치(40)와 일체로 이루어지는 크레인몸체(50)를 설치하여 후크(72)가 조정 가능한 크레인장치(100)를 구성하고 있다.An upper portion of the drive frame 30 is provided with a crane body 50 integrally formed with the boom stand take-off device 40 to constitute a crane device 100 which the hook 72 is adjustable.

상기 구동프레임(30)은 상기 차체프레임(10) 내에 평행하게 설치한 레일(20a)(20b)의 안내에 따라 이동실린더(32)의 신축작용으로 길이방향으로 직선왕복운동을 이루게 되고, 상단에 설치된 크레인몸체(50)와 동시에 이송거리를 갖게 된다.The drive frame 30 is a linear reciprocating motion in the longitudinal direction by the expansion and contraction action of the movable cylinder 32 in accordance with the guide of the rails 20a, 20b installed in parallel in the body frame 10, Simultaneously with the installed crane body 50 will have a transport distance.

따라서, 견인이나 비견인시에 이동실린더(32)의 작동에 의하여 직선왕복운동을 이루게 되므로 견인차량에서 크레인장치(100)의 이동을 가능하게 한다.Therefore, since the linear reciprocating motion is achieved by the operation of the moving cylinder 32 at the time of towing or towing, it is possible to move the crane device 100 in the towing vehicle.

여기서 상기 레일(20a)(20b)의 내면에는 상기 구동프레임(30)의 행정거리를 설정하기 위해서 전, 후로 전후방감지센서(60a)(60b)가 설치되어 구동프레임(30)이 접근되면 감지에 의해 이동실린더(32)의 작동 또는 정지를 이루게 되어 직선왕복운동의 행정거리를 결정하여 이동영역을 얻을 수 있도록 한다.Here, the front and rear detection sensors 60a and 60b are installed on the inner surface of the rails 20a and 20b to set the stroke distance of the drive frame 30 so that the drive frame 30 is approached. By the operation or stop of the movement cylinder 32 is to determine the stroke distance of the linear reciprocating motion to obtain a moving area.

이는 견인차량의 공차 시에는 구동프레임(30)에 설치된 크레인몸체(50)가 뒷쪽으로 이동되고 적차 시에는 앞쪽을 이동하기 때문에 언더리프트 또는 견인대로 견인시에 앞, 뒤축중의 무게 분산을 이루게 되고, 특히 견인시에 뒷축에 하중이 과도하게 걸리는 것을 해소하면서 뒷축으로 하중이 몰림으로 발생하는 조향의 문제가 없이 안전한 조향 작용을 이루게 한다.This is because the crane body 50 installed in the drive frame 30 is moved to the rear when the tolerance of the towing vehicle is moved to the rear and the front is moved when loading the undercarriage to achieve the weight distribution of the front and rear axles when towing with an underlift or towing. In particular, it eliminates the excessive load on the rear axle during towing, and achieves safe steering without the problem of steering caused by the load on the rear axle.

한편, 크레임몸체(50)의 상단에는 붐대인출장치(40)가 설치되고 이 붐대인출장치는 적어도 1단 이상의 다단 인출이 가능 한 붐대(70)가 설치되어 있어서 견인작업시 작업반경을 증대할 수 있고, 말단에 승강작용하는 후크(72)의 작용범위로 가감조정할 수 있게 된다.On the other hand, the boom stand take-out device 40 is installed on the upper end of the frame body 50, the boom stand take-out device is provided with a boom stand 70 that is capable of at least one or more stages of multi-stage drawer can increase the working radius during towing operation And it can be adjusted to the operating range of the hook 72 to elevate to the end.

본 고안에서는 상기와 같은 이동실린더(32)의 작동에 의하여 구동프레임(30)의 왕복운동을 가능하게 할 뿐만 아니라 랙과 피니언 방식의 구동장치에 의하여 상기 작용을 실현 가능한 것으로 이는 제작시 설계자의 설계에 의하여 선택되는 것이 바람직하다.In the present invention, not only the reciprocating motion of the drive frame 30 is enabled by the operation of the movable cylinder 32 as described above, but also the rack and the pinion type drive device can realize the above-described action, which is designed by the designer at the time of manufacture. It is preferable to select by.

이와 같은 본 고안은 언더리프프트 또는 견인대로 견인시에 앞, 뒤축중의 무게분산을 위하여 크레인을 앞으로 보내게 된다.This invention is to send the crane to the front for the weight distribution of the front, rear axle when towing the underlift or towing.

또한 견인시에는 뒷축에 하중이 과도하게 걸리고 앞축의 축중의 일부도 뒷축으로 몰리게 되어 뒷축의 축중앙오버의 앞축의 축중 감소로 인하여 조향의 문제가 발생하는 것을 해결하기 위해서 크레인을 공차 시에는 뒷쪽으로 적차 시에는 앞쪽을 보내어 앞,뒤 축중의 하중을 분배한다.In addition, during the towing, excessive load is applied to the rear axle, and part of the front axle is driven to the rear axle, so that the steering problem occurs due to the reduction of the axle of the front axle of the center axle of the rear axle. When loading, send the front to distribute the load on the front and rear axles.

따라서 견인시나 비견인시에 적정한 크레인 위치를 선정할 수 있으며 견인작업시 발생하는 하중문제를 크레인위치이동에 의해 해소하여 안정되고 편리하며 용이한 작업환경을 이루게 한다.Therefore, it is possible to select the appropriate crane position during towing or non-towing and to solve the load problem caused by the towing operation by moving the crane position to achieve a stable, convenient and easy working environment.
