Description

Technical Field

[0001] The invention relates to the technical field of steel-wood structure packaging boxes, in particular to a large-scale heavy equipment steel-wood structure packaging box and a processing technology thereof. Background Art

[0002] With the rapid development of modernization and automation technology, various equipment and instruments have been invented and manufactured and widely used in production. These equipment are large and small, heavy and light. During transportation, in order to avoid collision damage and shelter from wind and rain, they usually need to be packaged and protected with structures similar to large wooden boxes.

[0003] The traditional method of making wooden boxes for transport carriers is to assemble the base with wooden sleepers and wooden boards, and the side panels, end panels, and cover panels are assembled with wooden strips and wooden boards. When encountering super-heavy equipment, large-sized wooden sleepers are generally used as the base. When encountering super-long equipment, the wooden sleepers are not long enough and need to be spliced. However, due to the long length of the splicing or the joints of the splicing, the wooden sleepers are too large or the joints are not firm, which reduces the strength of the entire packaging box base. When the length of the wooden sleepers is spliced, the strength of the wooden sleepers is reduced due to the joints, resulting in the packaging's external dimensions being too large, making it difficult to lift and transport.

[0004] The steel-wood structure packaging box proposed in this technical solution is made of channel steel and wooden planks to make the base, wooden planks and planks to make the side panels / end panels / cover panels, and then the equipment is loaded and fixed on the base, and the side panels, end panels and cover panels are assembled to form an integral packaging box to meet the needs of equipment protection and transportation. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in the traditional wooden box manufacturing, the base is assembled by wooden sleepers and wooden boards, and the side panels, end panels and cover panels are assembled by wooden strips and wooden boards. When encountering super-heavy equipment, super-large-scale wooden sleepers are generally used as the base. When encountering super-long equipment, the length of the wooden sleepers is not enough, and the length of the wooden sleepers is spliced, resulting in the wooden sleepers being too large and insufficient in strength. When the length of the wooden sleepers is spliced, the strength of the wooden sleepers is reduced due to the joints, resulting in the packaging size being too large, making it difficult to lift and transport.

[0006] The present invention adopts the following technical scheme to solve the above technical problems: a large-scale heavy equipment steel-wood structure packaging box and its processing technology, including a box body in the shape of a rectangular parallelepiped, the bottom surface, two long side sides, two wide side sides, and the top surface of the box body are respectively composed of a base, two side plates, two end plates, and a top cover, the two side plates are connected to the base through a threaded fastening structure, the two end plates are connected to the base through a threaded fastening structure, the top cover is connected to the two side plates through a fixing plate, and the top cover is connected to the two end plates through a fixing plate.

[0010] The third step is to stack the wooden boards one by one, and use foam glue to stick the two adjacent wooden boards together. After each layer of foam glue is applied, use an extrusion device to squeeze it and scrape off the overflowed glue. This operation is repeated until the wooden boards are completed to form a wooden square of the required size.

[0021] The present invention adopts the above technical solution, and has the following technical effects compared with the prior art:

[0022] (1) Channel steel is arranged in the base, and the channel of the channel steel is filled with wood to form a steel-wood composite structure. The channel steel bears the effects of tension and shear force, and the wood bears the effects of pressure and stress, thereby greatly enhancing the strength of the base.
