Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a trailer that is towed and connected to a tractor, for example, and a container that is loaded on a ship or aircraft to transport cargo. Conventionally, a conveyor belt that slides the cargo conveying side onto the floor surface inside the container body is stretched, and a load chain that moves the partition gate and the conveyor belt are respectively connected to a partition gate that moves back and forth within the content body. However, a technology in which the transmission shaft interlockingly connected to the load chain is driven from outside the container body by a drive unit provided separately from the container body (for example,
55-165840) was issued. However, in the prior art, the output shaft of the drive unit is fitted into a gear connected to the transmission shaft to connect the transmission shaft and the output shaft, so the drive unit moves during operation and the output shaft tends to come off the gear. Moreover, the rotating output shaft remained exposed to the outside, making the connection work dangerous.

However, the present invention solves all of the above-mentioned drawbacks by providing a conveyor belt that slides the cargo conveyance side against the floor surface of the container body, and attaches this partition to the partition gate that moves reciprocally within the container body. A load chain for moving the gate and the conveyor belt are connected to each other, and a transmission shaft for driving the conveyor belt via the load chain is provided so as to be exposed outside the container body, and a drive unit including an engine is provided. In the structure in which the external driving force of the drive unit is transmitted to the transmission shaft to drive the conveyor belt inside the container main body, a shaft case into which the transmission shaft is loosely inserted is provided, and the shaft case is connected to the drive unit. The output shaft of the drive unit and the transmission shaft are removably connected and fixed by a holder, and the output shaft of the drive unit and the transmission shaft are separably coupled within the shaft case, and the drive unit is securely fixed to the shaft case of the container body via the holder. After that, by connecting the transmission shaft and output shaft within this shaft case, it is possible to prevent separation of the transmission shaft and output shaft due to movement of the drive unit as in the conventional case, and also to connect the transmission shaft and output shaft within the shaft case. This makes it possible to prevent the transmission shaft from being exposed to the outside, and to make the connection between the transmission shaft inside the container body and the drive unit outside the container body more complete than in the past, and to make the connection work easier and safer. The purpose of this project is to provide a container for carrying and transporting cargo.
