Description

  The present invention relates to a vehicle with an inclined cargo platform having an inclined cargo platform that is rotatable between a horizontal position and an inclined position inclined with respect to a chassis frame.

  When carrying a load by a trailer or a truck, it is necessary to drive the vehicle so that the load does not protrude outward from the side surface of the vehicle for safe driving. When a large panel material with dimensions exceeding the width of the vehicle, such as steel plates used in ships and plants, is transported by a trailer, if the large panel is loaded horizontally on the loading platform, the panel material will be Since it is not possible to make the traffic safe by projecting outward from the side, conditions such as the traffic time zone and the arrangement of the guided vehicle are imposed. Therefore, in order to transport large panel materials while ensuring the safety of road traffic without being restricted by traffic hours, etc., a trailer with an inclined cargo bed is attached to the trailer chassis frame so that it can rotate freely. in use. In this type of trailer, the tilting platform is pivotally attached to the chassis frame via a hinge so that the tilting platform, that is, the tilt frame, has the side on one side as the center of rotation and the other side rises. (For example, refer to Patent Document 1).

Such an inclined carrier of the trailer has a rectangular shape corresponding to the chassis frame of the trailer, and has a frame made of steel and a floor plate attached to the steel frame. The inclined carrier is positioned below the floor plate. A plurality of rod-shaped telescopic bolsters are mounted so as to be movable back and forth in the vehicle width direction, that is, slidable. When transporting large panels, pull out each telescopic bolster from the tilted platform and raise one side of the tilted platform to make it tilted without causing the large panel to protrude beyond the width of the trailer. It can be transported safely.

  A support block is fixed to the tip of the telescopic bolster.When the telescopic bolster is pulled out when a large panel is loaded on the inclined platform, the load support surface of the support block is the same as the floor surface of the inclined platform, so The large panel can be transported in a flat state without bending the large panel.

  In this way, a support block for forming the same load support surface as the floor surface of the tilted cargo bed with the telescopic bolster pulled out is attached to the tip of the telescopic bolster that is attached to the lower side of the floor plate so as to be movable forward and backward. When the telescopic bolster is retracted into the inclined platform, the frame piece for forming the side of the inclined platform is attached to the support block so that the load supporting surface of the support block is flush with the floor plate.

  Therefore, for example, when eight telescopic bolsters are mounted on an inclined cargo bed, it is necessary to provide nine steel materials, each constituting a frame piece, on the side on the vertical movement side of the inclined cargo bed. The strength of the tilting platform depends greatly on the strength of the side and end sides. When the steel material on the side is formed by multiple members divided at the position of the telescopic bolster as in the past, There is a problem that the side strength is lowered and the side is bent. In order to prevent the occurrence of such bending of the inclined platform, it is necessary to increase the number of longitudinal beam members provided in the center in the width direction of the inclined platform so as to extend in the vehicle traveling direction. When the number of the longitudinal beam members is increased, the weight of the inclined loading platform increases, and the weight of the trailer cannot be increased by reducing the weight of the entire trailer.
