Foldable multipurpose standard container

Abstract

The invention discloses a foldable multipurpose standard container. The foldable multipurpose standard container comprises a main container body and an auxiliary container body. The main container body comprises a longitudinal bearing beam, a transverse bearing beam and vertical bearing stand columns. The longitudinal bearing beam is provided with a square hole of a hollow structure. The auxiliary container body comprises a sliding beam inserted into the square hole. A bearing square frame is arranged on the side, away from the main container body, of the sliding beam. The bearing square frame comprises a container body door frame and a container door. An auxiliary top plate, an auxiliary bottom plate and an auxiliary side plate are welded to the peripheral side of the container body door frame and inserted into the main container body. The main container body is provided with a transmission mechanism used for adjusting the position of the auxiliary container body. The auxiliary container body is arranged in the main container body in a sliding manner. After transportation is completed, the auxiliary container body is inserted into the main container body, the space occupied by the whole container is reduced, empty container transportation is conducted according to the container size of 20 feet, the freight space occupied by the container is smaller, 50% of space can be saved, and the transportation cost of empty container returning is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of containers, in particular to a foldable multipurpose standard container. Background technique [0002] Freight containerization is the current standardized mode of transportation. The speed of container cargo ships is twice that of ordinary cargo ships, and its speed is as high as more than 30 nautical miles per hour. The time for loading and unloading containers at the port is more advantageous, which greatly reduces operating costs. Because of the fast arrival, Naturally, both buyers and sellers can save money and reduce storage costs. Reduce cargo damage. The goods in the container are no longer directly hoisted in and out, so the possibility of collision, extrusion, and damage is reduced. When the container is transporting perishable goods, it can be kept normal in the container with refrigeration and constant temperature equipment, which simplifies the packaging and saves packaging materials; the s...

Problems solved by technology

[0003] Although containerized transportation has many advantages, there is still a world problem that has not been solved since it was first invented and used, that is, due to the unbalanced flow of goods, it is impossible to return heavy boxes and empty boxes still occupy the same amount as heavy boxes. Due to the large number of shipping spaces, nearly half of the cargo ships return empty containers to the port with empty loads, resulting in a huge loss of transport capacity, which cannot reduce the cost of returning empty containers. Because only one end of the container is widely used, and the other five sides are closed. It brings inconvenience to packing and unpacking. Due to the limitation of the width and height of the door at one end, it is impossible to use large-scale loading equipment to mechanize the work. Only small machinery and manual work can be used for packing and unpacking, resulting in long working hours. Low efficiency, unbalanced loading on the up, down, front, back, and left and right sides, etc., there are improvements in the existing technology
