Pallet device for cargo transportation

Abstract

The present invention relates to a pallet device used for cargo transport. The pallet device used for cargo transport is not associated to difference on weight or size of loaded cargos, plays a stable anti-vibration role, and can help to greatly reduce necessary transport costs. An anti-vibration pallet (P) is provided with a joint mechanism (J), side faces of an upper stand (11) and a lower stand (12) are oppositely joined on the same plane; and one upper stand and one lower stand are set as a unit and are joined by the joint mechanism to assemble a pallet assembly body of a corresponding size according to the size the transported cargoes (D). An anti-vibration mechanism (V) comprises non-linear compression coil springs (35) having non-liner spring characteristics, and the spring constant of the compression coil springs are set, so as to enable inherent frequency to be constant in a certain weight range, even of the loading weight of the transported cargos changes.

Description

[0001] technology area [0002] The present invention relates to a pallet device for cargo transportation, which is loaded with cargo such as shipping cargo, sea cargo, railway cargo, and road cargo, and loaded into the cargo room of a conveying device such as an airplane, ship, train, and truck. Anti-vibration function of vibration or shock. Background technique [0003] In various cargoes, such as air cargo, if turbulence occurs during air transportation, and the aircraft shakes, it will receive a strong impact and generate severe vibration. Even at the airport before departure or after arrival, when it is transported on a pallet trolley , Vibrates violently due to violent shaking, and precision equipment sensitive to the vibration / shock is sometimes damaged by shipping goods. Therefore, the conventional pallet device for shipping goods is provided with elastic bodies such as rubber or coil springs. The anti-vibration mechanism is used to carry the shipping cargo through th...

Problems solved by technology

Therefore, in the past, even when transporting relatively light small shipping goods such as 500kg in weight, a relatively large general-size box with a volumetric weight of 2000kg was used in consideration of the margin for the fixed binding box. Therefore, it is suitable for shipping according to the heavy volumetric weight. There is a problem of shipping freight rates that need to be reduced and there is so much waste

[0009] In addition, conventionally, in the pallet device for cargo transportation, the size of the shipping cargo carried on the anti-vibration pallet to be transported varies depending on the consignor on the side of the consignment of the shipping cargo, and varies from large, medium, to small. On the other hand, usually, it is necessary to prepare anti-vibration pallets of different sizes according to the size of the shipping goods that are entrusted with the transportation.
