At present, an electric conveying line device used in combination with an electron accelerator irradiation device in the industry generally adopts an electric stainless steel roller conveying device, when products or goods are conveyed to the irradiation device for irradiation, due to the fact that two ends of a tray for conveying the goods do not have limiting mechanisms, when the tray moves on a conveying line and is inclined in the left-right transverse position, guard plates on two sides of the tray and two sides of the electric conveying line are prone to collision and blocking, and further a chuck phenomenon is caused. Also, when the pallet transports products or goods, there is a possibility that the slip speed between the lower end of the pallet and the upper end of the drum becomes slow (particularly, liquid including lubricating oil adheres to the lower end of the pallet or the upper end of the drum for various reasons), and thus, the irradiated products or goods may be damaged due to the long heating time. Finally, because the distance between the plurality of transmission rollers of the electric stainless steel roller conveying equipment is small, the rollers adjacent to the lower end of the irradiation equipment are not easy to radiate heat because of being irradiated at high temperature for a long time, the lubricating effect is influenced, the rollers are easy to damage after being used for a long time, and further great influence is brought to conveyed products or goods. In summary, it is necessary to provide a conveying device that does not use a roller as a carrier for conveying, and can prevent a pallet from slipping and a chuck during conveying goods or products, thereby effectively ensuring good irradiation effect of the products or goods.
