The present invention relates to a door opening and closing apparatus of a special purpose truck equipped with a loading box for loading cargo inside. The opening and closing apparatus includes a lower body having one end fixedly mounted in the direction of the side door in the loading box of the special purpose truck and an upper body hinged to one end of the lower body at a remote side from the side door and pivoting about a first hinge axis. The length of the upper body is longer than the length of the lower body. Upper engaging means and lower engaging means are respectively mounted on side facing each other during the pivoting of the lower body and the upper body. Accordingly, when the upper body is rotated in the direction of the lower body, the upper engaging means on the upper surface of the upper body and the lower engaging means of the lower body are engaged with each other, and then the end of the upper body protruding more than the lower body presses the hinged side door of the loading box. Accordingly, with the door opening and closing apparatus of a special purpose truck of the present invention, the side or rear door of the special purpose truck can be opened and closed with ease. In addition, a driver can accurately recognize the open and closed states of the side door or the rear door by means of a contact sensor, and thus safety driving can be performed.

    본 발명은 내부에 화물을 적재할 수 있도록 적재함이 장착되어 있는 특장차의 도어 개폐장치에 관한 것으로서, 더욱 상세하게는 상기 개폐장치는 특장차의 적재함에 일단이 측면도어 방향으로 고정장착되는 하부몸체와, 상기 하부몸체의 양단부 중 측면도어로부터 원거리 측에 위치한 일단이 힌지결합되어 제1힌지축을 중심으로 회동하는 상부몸체로 이루어지되, 상기 상부몸체의 길이가 하부몸체의 길이보다 길게 형성되어 있는 것으로, 상기 하부몸체와 상부몸체가 회동시 마주보는 각각의 면에는 각각 상부걸림수단과 하부걸림수단이 장착되어 있어, 상기 상부몸체가 하부몸체 방향으로 회동하면 상부몸체의 상면에 장착된 상부걸림수단과 하부몸체의 하부걸림수단은 서로 체결되면 하부몸체보다 더 돌출되는 상부몸체의 끝단부가 적재함에 여닫이 형식의 측면도어를 압박하는 것이 특징인 특장차의 도어 개폐장치에 관한 것이다. 따라서, 본 발명 특장차의 도어 개폐장치는 특장차의 측면도어 또는 후면도어를 열고 닫는 것이 용이하고, 또한 접촉센서에 의해 측면도어 또는 후면도어의 열린상태와 닫힌 상태를 운전자가 정확히 인지하여 안전운행을 할 수 있다는 등의 현저한 효과가 있다.
