일반적으로, 모래나 자갈과 같은 건축자재를 운송하는 덤프트럭은, 견고하게 제작되어 사용되었으며 특히, 모래 또는 자갈과 같은 건축자재가 적재되는 데크는 충분한 강성을 갖도록 제작되며 적재된 건축자재의 용이한 하역을 위하여 데크가 자동차의 후방으로 상승되도록 하여 적재된 건축자재의 하역이 용이하도록 하였다.In general, dump trucks for transporting construction materials such as sand or gravel have been firmly manufactured and used. In particular, decks on which construction materials such as sand or gravel are loaded are manufactured to have sufficient rigidity. The deck was raised to the rear of the car for unloading so that the loaded building materials could be easily unloaded.
이때, 데크의 후방에는 데크도어가 제1도에 도시된 바와같이 개폐 가능하게 구비되고, 이 데크도어(60)의 상부 양측에는 회동 가능하게 데크(50)에 결합된 힌지부(61)가 형성됨과 더불어 하부에는 열림을 방지하기 위한 잠금부(70)가 구비된다.At this time, the deck door is provided at the rear of the deck so as to be open and close as shown in FIG. 1, and hinge parts 61 coupled to the deck 50 are rotatably formed at both upper sides of the deck door 60. In addition, the lower portion is provided with a locking portion 70 to prevent opening.
여기서, 이 잠금부(70)는 하방향으로 돌출 형성되어 측 방향으로 잠금핀(72)이 결합되는 결합공이 형성된 도어잠금부(71)와, 이 도어잠금부(71)를 관통한 잠금핀(72)이 관통되는 결합공이 형성되며 데크(50)에서 후방으로 돌출 형성된 데크잠금부(72)로 구성된다.Here, the locking part 70 is formed to protrude downward and the door locking portion 71 is formed with a coupling hole for coupling the locking pin 72 in the lateral direction, and the locking pin (through the door locking portion 71) ( A coupling hole through which 72 is formed is formed, and the deck lock portion 72 protrudes backward from the deck 50.
상기와 같이 된 덤프트럭의 데크도어(60)는 데크(50)에 적재된 건축자재를 하역하기 위하여는 우선 데크도어(60)의 하부에 구비된 잠금부(10)의 잠금핀(72)을 제거한 후 데크(50)를 상승시켜 건축자재를 하역하였다.The deck door 60 of the dump truck as described above, in order to unload the building materials loaded on the deck 50, first the locking pin 72 of the locking portion 10 provided in the lower part of the deck door 60 After removal, the deck 50 was raised to unload the building materials.
그러나, 상기한 바와같이 데크(50)에 적재된 건축자재를 하역하기 위해서는 잠금핀(72)을 제거하여야 하였으며, 상기와 같이 잠금핀(72)을 제거하는 과정에 있어서 데크(50)에 적재된 건축자재의 자중에 의하여 데크도어(60)가 개방되어 적재된 건축자재가 개방된 데크도어(60)를 통하여 쏟아지므로 작업자가 부상을 입게 된다.However, in order to unload the building materials loaded on the deck 50, as described above, the locking pin 72 had to be removed, and the lock pin 72 was removed in the process of removing the locking pin 72 as described above. Deck door (60) is opened by the weight of the building materials, the building materials are loaded through the open open deck door (60) and the worker is injured.
따라서, 본 발명은 상기와 같은 문제점을 해소하기 위하여 데크가 들어올려짐과 동시에 자동으로 데크도어가 개폐되도록 함을 본 발명의 목적으로 한다.Accordingly, an object of the present invention is to automatically open and close the deck door at the same time the deck is raised to solve the above problems.

상기 목적을 달성하기 위한 본 발명의 구성은, 데크의 힌지브래킷에는 잠금부가 힌지고정되고, 이 잠금부의 전단에는 데크도어의 하부에 구비된 고정봉을 구속하도록 된 걸고리부가 형성됨과 더불어 후단에는 중량부가 형성되며, 이 중량부의 하부 차체에는 상기 잠금부의 잠금상태를 유지하도록 된 스토퍼가 구비되어 구성된 것이다.The construction of the present invention for achieving the above object, the hinge bracket of the deck, the locking portion is hinged fixed, the front end of the lock portion is formed with a hook portion to restrain the fixed rod provided on the lower portion of the deck door and the weight portion at the rear end It is formed, the lower body of the weight portion is provided with a stopper to maintain the lock state of the lock portion.
이하 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings.
제3도는 본 발명이 적용된 덤프트럭의 배면도이고, 제4도는 본 발명이 적용된 덤프트럭의 측면도이며, 제5도는 본 발명의 작동상태를 보인 덤프트럭의 측면도로서, 본 발명의 구성은, 데크(50)가 덤핑시 회동될 수 있도록 차체(100)에 힌지결합시키는 힌지브래킷(51)의 힌지점 상부에 잠금부(10)가 회동 가능하게 힌지고정된다.3 is a rear view of the dump truck to which the present invention is applied, and FIG. 4 is a side view of the dump truck to which the present invention is applied, and FIG. 5 is a side view of the dump truck showing the operating state of the present invention. The locking portion 10 is pivotally hinged to the upper portion of the hinge point of the hinge bracket 51 which is hinged to the vehicle body 100 so that the 50 can be rotated when dumping.
그리고, 이 잠금부(10)의 전단에는 데크도어(60)의 하부에 구비된 고정봉(20)에 걸려져 상기 고정봉(20)을 구속할 수 있도록 된 걸고리부(11)가 형성됨과 더불어 후단에는 데크(50)가 덤핑시 걸고리부(11)가 고정봉(20)에서 이탈될 수 있도록 자중에 의하여 잠금부(10)를 회동시키는 중량부(12)가 형성된다.And, the front end of the locking portion 10 is hooked to the fixed rod 20 provided on the lower portion of the deck door 60, the hook portion 11 is formed to restrain the fixed rod 20 is formed At the rear end, the weight portion 12 is formed to rotate the locking portion 10 by its own weight so that the hook portion 11 can be separated from the fixed rod 20 when the deck 50 is dumped.
또한, 이 중량부(12)의 하부 차체(100)에는 데크(50)가 덤핑되어 적재된 건축자재를 모두 하역시키고 하강을 완료했을 때 걸고리부(11)가 데크도어(60)의 고정봉(20)과 결합되어 잠금상태를 유지할 수 있도록 중량부(12)의 하측을 지지하는 스토퍼(30)가 구비된다.In addition, the lower body 100 of the weight portion 12, the deck 50 is dumped to load all the building materials loaded and the hook portion 11 is the fixed rod of the deck door 60 when completed 20 is provided with a stopper 30 for supporting the lower side of the weight part 12 so as to be coupled to maintain the locked state.
한편, 상기 데크도어(60)의 하부 양측에는 상기 잠금부(10)의 걸고리부(11)가 결합되도록 봉형으로 고정된 고정봉(20)이 구비되어 있다.On the other hand, the lower side of the deck door 60 is provided with a fixed rod 20 fixed in a rod shape so that the hook portion 11 of the locking portion 10 is coupled.
이하 작용에 대하여 상세히 설명하면 다음과 같다.Hereinafter, the operation will be described in detail.
상기와 같이 된 본 발명에 따른 데크도어 개폐장치는, 운전자가 데크(50)에 적재된 건축자재를 하역하기 위하여 상기 데크(50)를 덤핑시키면, 이 데크(50)를 차체(100)에 회동 가능하게 결합시킨 힌지브래킷(51)에 힌지 결합된 잠금부(10)가 덤핑되는 데크(50)의 각도에 따라 중량부(12)의 자중에 의하여 회동되어 데크도어(60) 하부의 고정봉(20)과 결합된 걸고리부(11)가 해제된다.Deck door opening and closing device according to the present invention as described above, when the driver dumped the deck 50 to unload the building materials loaded on the deck 50, the deck 50 is rotated to the vehicle body 100 The locking rod 10 hinged to the hinge bracket 51 capable of being coupled is rotated by the weight of the weight portion 12 in accordance with the angle of the deck 50 to be dumped so that the fixed rod (below the deck door 60) ( Hook portion 11 coupled with 20 is released.
그러므로, 데크도어(60)의 잠금상태가 해제되어 데크(50)에 적재된 건축자재의 자중에 의하여 개방되어 상기 건축자재가 데크도어(60)를 통하여 배출되므로 하역이 완료된다.Therefore, the lock state of the deck door 60 is released and opened by the weight of the building material loaded on the deck 50, so that the building material is discharged through the deck door 60, so the unloading is completed.
상술한 바와 같은 과정을 통하여 적재된 건축자재의 하역이 완료되고 덤핑된 데크(50)가 하강되면, 중량부(12)의 하부가 스토퍼(30)에 의하여 지지되어 데크(50)가 하강됨에 따라 잠금부(10)가 회동되므로 걸고리부(11)가 고정봉(20)에 걸려진다.When the loading and unloading of the dumped deck 50 is completed through the process as described above, the dumped deck 50 is lowered, as the lower portion of the weight portion 12 is supported by the stopper 30 as the deck 50 is lowered Since the locking portion 10 is rotated, the hook portion 11 is caught by the fixed rod 20.
이상과 같이 된 본 발명에 따른 데크도어 개폐장치는, 데크에 적재된 건축자재를 하역하기 위하여 데크도어의 개폐장치를 해제하기 위한 별도의 과정을 거치지 않고 데크를 덤핑시킴과 동시에 잠금상태가 해제되므로 운전자에게 편리함을 제공하며, 수작업에 의한 데크도어 개폐장치의 잠금상태 해제로 인한 작업자의 부상이 방지되는 매우 유용한 것이다.Deck door opening and closing device according to the present invention as described above, without dumping the deck without a separate process for releasing the opening and closing device of the deck door to unload the building materials loaded on the deck, so the locked state is released at the same time It provides convenience to the driver and is very useful to prevent the injury of the operator due to the unlocking of the deck door opening and closing device by hand.
