[0029] 1. The present invention, when transferring cargo boxes on board, installs the conveying frame at the position of conveying cargo on board, places cargo on the feeding roller on one side through the handling equipment on board, starts the feeding motor, and the output end of the feeding motor drives the input end of the feeding gearbox to rotate, and the output end of the feeding gearbox drives the feeding universal coupling to rotate through the deceleration and torque increase of the feeding gearbox, and the rotation of the feeding universal coupling drives the feeding rotating rod to rotate, and the rotation of the feeding rotating rod drives the bevel gear 2 to rotate, and the rotation of the bevel gear 2 drives the bevel gear 1 to rotate, and the conveying rotating rod connected thereto is driven to rotate through the rotation of the bevel gear 1, and the conveying sprocket is driven to rotate through the rotation of the conveying rotating rod, and the rotation of the conveying sprocket drives the conveying chain transmission, and at the same time drives another conveying rotating rod to rotate, when the conveying sprocket is transmitted, the conveying sprocket drives the feeding tooth plate to move, and when the feeding tooth plate moves, the feeding tooth plate drives the feeding gear to rotate under the meshing of the feeding tooth plate and the corresponding feeding gear, and the rotation of the feeding gear drives the feeding roller to rotate, and the cargo is transported through the rotation of the feeding roller;

[0030] 2. The present invention, when the feeding motor is started to drive the conveying rotating rod to rotate, the rotation of the conveying rotating rod will drive the bevel gear four to rotate, the rotation of the bevel gear four drives the bevel gear three to rotate, the rotation of the bevel gear three drives the air supply rotating rod to rotate, the rotation of the air supply rotating rod drives the air supply turntable to rotate, the rotation of the air supply turntable drives the air supply slider to move, the movement of the air supply slider drives the air supply slide to perform linear reciprocating motion on the air supply rack, the movement of the air supply slide drives the inflation slide to move, the movement of the inflation slide drives the inflation slide to move, when the inflation slide moves in the inflation cylinder in the direction away from the three-way air pipe, the external gas enters the inflation cylinder through the air inlet pipe and the air inlet check valve, when the inflation slide moves in the direction close to the three-way air pipe, the gas in the inflation cylinder will be compressed into the air storage box through the inflation pipe and the inflation check valve, by setting the pressure relief value of the pressure relief valve, when the air pressure in the air storage box reaches the preset value, the excess gas will be discharged through the pressure relief valve;

[0031] 3. The present invention starts the feeding motor, and while the feeding roller drives the goods to move, when the position detection sensor detects the goods, the air supply valve corresponding to the position detection sensor is opened, and the gas in the air storage box is discharged into the positioning cylinder through the inflation main pipe, the positioning air supply pipe and the positioning exhaust pipe. When the air pressure in the positioning cylinder increases, the positioning rod moves toward the end of the positioning cylinder away from the positioning exhaust pipe. The movement of the positioning rod drives the positioning plate to move, and the movement of the positioning plate drives the positioning pressure sensor to move, while stretching the positioning spring. The movement of the positioning pressure sensor drives the support frame and the positioning roller to move, so that the positioning roller contacts the cargo box. When the positioning pressure sensor reaches a preset value, , the air supply valve is closed, and as the positioning roller rotates, it contacts the cargo box and fixes the position of the cargo box. In the actual transportation process, when the cargo box moves toward the positioning roller due to the shaking of the hull, the positioning rod moves toward the positioning cylinder, and the gas in the positioning cylinder is compressed, which can play a certain buffering role. As the air pressure in the positioning cylinder continues to increase, it will provide greater support for the cargo box, so that the cargo box will not roll over. In addition, the positioning pressure sensor monitors the contact pressure between the cargo box and the positioning roller in real time, and the tilt of the cargo can be intuitively judged. By analyzing the pressure data, the completion of the cargo box can be judged.

[0032] 4. In the present invention, after the position detection sensor senses that the cargo box is separated from the positioning roller, the exhaust valve is activated, and the gas in the positioning cylinder is discharged through the positioning exhaust pipe. Under the rebound tension of the positioning spring, the positioning rod will move back into the positioning cylinder to reset the position of the pneumatic positioning mechanism. Under the movement of multiple pneumatic positioning mechanism simplifies, the cargo box can be ensured to be stably transported on the feeding roller, and the problem of the cargo box tipping over can be effectively avoided.
