The purpose is to open and close easily and easily.

を著しく阻害するものとなる。Conventional technology Conventionally, a roof frame opening/closing device for a freight vehicle that opens and closes a roof frame in the form of an airfoil has a roof frame opening/closing device for a freight vehicle that opens and closes a roof frame in the form of an airfoil. There is a roof frame equipped with a cylinder that opens and closes the roof frame. However, in this invention, since the cylinder is provided on the rear underframe, there is a drawback that the design is significantly restricted when an opening/closing door is provided on the rear underframe. In other words, even though a roof frame is provided, depending on the conditions at the loading/unloading site, it may not be possible to open the roof frame for loading and unloading, and the loading and unloading work may have to be done from the rear. Therefore, the reality is that the rear underframe is also equipped with an opening/closing door. When installing this opening/closing door on the rear underframe, installing a cylinder on the rear underframe may make it difficult to open/close the opening/closing door, or the opening/closing door must be made small, which significantly impedes loading and unloading work. becomes.

できない欠点を有している。 There is also a device in which the cylinder is installed in the front underframe, such as the device described in Japanese Utility Model Application Publication No. 56-118117, but in this device, the cylinder is installed inside the front underframe, that is, on the cargo compartment side. Because the cylinder occupies part of the cargo space, the area occupied by the device is large, and it is suitable for freight vehicles that can load many items and require a large opening for easy loading and unloading of these items. This is not desirable, and in order to reduce the occupation of this cargo space, the installation position of the cylinder is limited to the left and right direction at the top of the front underframe, and the positional relationship is the most favorable for opening and closing the roof frame. It has the disadvantage that a cylinder cannot be installed.

Both ends of the pair of roof frames to be covered in the longitudinal direction are supported by support shafts on the front and rear underframes, a hydraulic cylinder is installed on the outer surface of the front underframe on the driver's seat side, and one end of the cylinder is supported on the front underframe. At the same time, one end of the piston rod of this hydraulic cylinder is pivotally supported on the roof frame, and a spring that biases the roof frame in the opening direction is connected and fixed between the rear underframe and the roof frame, and the hydraulic cylinder provided on the front underframe is operated. As the piston rod advances and retreats, the roof frame rotates about the support shaft as a fulcrum, thereby opening and closing the roof frame.

ある。Operation In the structure as described above, in order to open and close the roof frame, a hydraulic cylinder installed on the outer surface of the front underframe is operated to cause the piston rod to protrude or retreat. As the piston rod moves forward and backward, the roof frame, which is supported by support shafts on the front and rear underframes, can be rotated about the support shafts to open and close the roof frame. Additionally, between the roof frames that are supported by support shafts on the rear underframe where no hydraulic cylinder is installed, a spring that biases the roof frame in the opening direction is connected and fixed, which assists when the roof frame is opened using the hydraulic cylinder. When the roof frame is energized and the roof frame is closed, it is possible to prevent the roof frame from rapidly falling and closing, and it is also possible to prevent the occurrence of a sudden load on the hydraulic cylinder due to the load of the roof frame.

ものである。 In the structure as described above, in order to open and close the roof frame 5, the hydraulic cylinder 10 is actuated to cause the piston rod 11 to protrude or retreat. As the piston rod 11 moves forward and backward, the roof frame 5, which is supported by the support shaft 6 on the front underframe 3 and the rear underframe 4, is rotated about the support shaft 6, thereby opening and closing the roof frame 5. In addition, a tension spring 12 is connected between the roof frame 5, which is supported by a support shaft 6 on the rear underframe 4 on which the hydraulic cylinder 10 is not installed, and which biases the roof frame 5 in the opening direction. Since it is fixed, when the roof frame 5 is opened by the hydraulic cylinder 10, an auxiliary force is applied, and when the roof frame 5 is closed, it is possible to prevent the roof frame 5 from suddenly falling and closing. This can prevent the sudden load caused by the load on the frame 5 from occurring.
