While the traction pin 32 is installed, the bracket 33a is welded at a predetermined position so that the opposite side of the supporting stand 4 hinged to the groove 24d is welded, and the roller 31 is fixed at the bracket 33a. The wire fixing bracket 33b is welded to the installed side.

한편 상기 받침고정대(4)는 제1고정대(41)와 제2고정대(42)로 이루어져 있는 바, 상기 제1고정대(41)의 한쪽은 회전뭉치(24)의 브라켓트(24b)에 형성된 요홈(24d)에 끼워져 힌지됨과 더불어 다른쪽은 핀으로 상기 붕대(33)의 소정위치에 용접고정된 브라켓트(33a)에 힌지되는 상기 제2고정대(42)의 인출길이를 조절할 수 있도록 되어 있다.On the other hand, the supporting stand 4 is composed of a first fixing stand 41 and the second fixing stand 42, one side of the first fixing stand 41 grooves formed in the bracket 24b of the rotating bundle 24 ( In addition to being hinged to 24d), the other side can adjust the lead length of the second fixing rod 42 hinged to the bracket 33a welded to the predetermined position of the bandage 33 with a pin.

다음에는 상기와 같은 구성으로 이루어진 본 발명 크레인의 설치와 사용상태를 설명한다.Next, the installation and use of the crane of the present invention having the above configuration will be described.

본 발명 크레인을 차량의 화물칸에 보울트와 너트를 매개로 고정시키고, 상기 모터(22)의 전원선을 밧데리에 연결하게 되면 간단히 설치가 완료된다.When the crane of the present invention is fixed to the cargo compartment of the vehicle through the bolt and the nut, and the power line of the motor 22 is connected to the battery, the installation is simply completed.

또한 사용방법은 차량의 측면에 적재된 화물을 크레인의 후크(22a)에 걸기 위해 붕대(33)를 밀어 화물이 놓인 곳으로 배치시키고, 상기 모터(22)에 연결된 스위치를 조작하여 와이어(22b)를 풀어서 화물에 후크(22a)를 걸은 후, 다시 스위치를 조작하여 와이어(22b)를 화물칸에 화물을 놓을 수 있는 정도로 감은 다음, 상기 붕대(33)를 손으로 밀어 회동시켜서 소정위치까지 회동시킨 후 와이어(22b)를 풀어서 화물을 화물칸에 적재시킬 수 있게 되는바, 이후 남은 화물을 화물칸에 모두 적재하기 위해서는 상기 기술한 바와 같이 반복하면 된다.In addition, the method is used to place the cargo loaded on the side of the vehicle by pushing the bandage 33 to hook the hook (22a) of the crane to the place where the cargo is placed, the wire 22b by operating the switch connected to the motor 22 After unhooking the hook (22a) to the cargo, and then again operating the switch to wrap the wire (22b) to the cargo compartment enough to place the cargo, and then rotate the bandage 33 by hand to rotate to a predetermined position It is possible to load the cargo in the cargo compartment by releasing the wire (22b), after which it is repeated as described above to load the remaining cargo in the cargo compartment.

여기서 상기 붕대(33)를 밀게 되면, 상기 회동장치부(2)의 회전축(25)과 지지부(1)의 회전지지관(13)이 베어링(21)을 매개로 회동가능하게되고, 상기 브라켓트(26)에 너트를 매개로 계지된 보조샤프트(23)와 붕대(33)의 브라켓트(33a)에 힌지결합된 받침고정대(4)를 매개로 설치된 회전뭉치(24)가 붕대(33)의 자중에 의해 지주축(12)의 외주면에 밀착되므로, 이때 상기 붕대(33)을 밀치면 지주축(12)의 외주면을 따라 회전뭉치(24)의 로울러(24a)가 구르게 되어 있기 때문에, 상기 지지부(1)의 지주축(12)을 회전중심으로 붕대(33)가 돌아가게 된다.When the bandage 33 is pushed, the rotating shaft 25 of the rotating device portion 2 and the rotating support tube 13 of the support portion 1 are rotatable via the bearing 21, and the bracket ( 26, a rotating bundle 24 installed via a support shaft 4 hinged to a bracket 33a of the auxiliary shaft 23 and the bandage 33, which is held by a nut, is attached to the weight of the bandage 33. Since it adheres to the outer circumferential surface of the support shaft 12, when the bandage 33 is pushed at this time, since the roller 24a of the rotating bundle 24 is rolled along the outer circumference of the support shaft 12, the support portion ( Bandage 33 is returned to the center of rotation of the support shaft 12 of 1).

또한 상기 브라켓트(33b)는 화물의 중량이 기준 중량보다 초과할 경우 와이어(22b)를 걸어서 이 와이어(22b)에 걸리는 하중을 감소시키기 위한 것이다.In addition, the bracket 33b is for reducing the load on the wire 22b by hanging the wire 22b when the weight of the cargo exceeds the reference weight.

이상 설명한 바와 같이 본 발명에 의하면, 기존 차량의 개조가 필요없이 보울트와 너트를 이용하여 누구나 간단히 설치할 수 있을 뿐만 아니라, 간단한 스위치 조작과 회전조작에 의해 크레인을 사용할 수 있도록 된 것이다.As described above, according to the present invention, anyone can easily install using a bolt and a nut without requiring modification of an existing vehicle, and use a crane by simple switch operation and rotation operation.
