Technical field

The invention relates to a container.

Background technique

A container is a large loading container that has a certain strength, rigidity and specifications and is designed for weekly use. The use of containers to transfer goods can be directly loaded in the shipper's warehouse, shipped to the consignee's warehouse for unloading, and when the car or ship is changed midway, the goods need not be taken out of the box. There are many types of containers, which are divided into steel, aluminum, glass steel, stainless steel, etc. according to the structure: inner column and outer column, folding and fixed, prefabricated and thin shell, etc. According to the use, it is divided into: grocery box, open top box, gantry type, platform type, refrigerated type, tank type and so on.

The container is mainly composed of a chassis structure, a door end (rear end) structure, a top end structure, a side wall structure, and an end frame (front end) structure. The bottom frame structure is composed of a bottom side beam, a bottom beam, a 20' fork groove/40' gooseneck groove, a bottom middle beam, a wooden floor and a guide beam; the door end (back end) structure is composed of inner and outer door posts and thresholds, Customs sealing plate, door panel, door beam, door square tube, door sill, door sill cover, lock rod fittings, corner pieces, channel steel, etc.; top structure consists of top plate, front and rear corner reinforcing plates; side wall structure by side panels, Top side beam, ventilator, rope ring, etc.; end frame (front end) structure consists of front corner column, end sill, end plate, end sill, end sill cover, gooseneck end sealing plate, corner piece, channel steel and so on.

However, existing containers on the market currently have the following drawbacks:

1. In order to ensure the inner width of the container and the strength of the side panels, the side panels need to extend beyond the bottom corners, and the outer surface of the outer door pillars of the outer door pillars of the container is fixedly connected to the side panels, and the side panels are provided with outwardly protruding reinforcing ribs. The inner surface of the lap joint edge of the outer door column of the container is flush with the inner surface of the side panel, and the outer surface of the reinforcing rib on the side panel protrudes beyond the outer surface of the lap joint edge of the outer door pillar of the container, and the side panel exceeds the bottom corner piece The size is 23mm, beyond The size is large, and only the containers of the same specification can be put together when the ship is transported, and the side plates of the adjacent two containers are also inter-plugged, which is very inconvenient to transport.

2. In order to enhance the structural strength of the container, the side plates of most existing containers are provided with reinforcing ribs protruding inwardly, but the reinforcing ribs protruding inwardly occupy an effective use space inside the container, and the size of the tray is Standard parts, so this type of container can usually only load one pallet in one row, with low loading rate and high transportation cost.

3. The shape of the standard lower side beam is C-type or double-Z type, and the height of the C-type lower side beam and the double-Z type lower side beam is short, which can not well protect the side bottom. When the container is hoisted on the ship, most of it is hoisted from the top, and most of the collision positions are at the bottom of the side. In addition, the box will also cause collision damage to the tray.

Fourth, in order to strengthen the strength of the side panels, the arch depth of the side panels is deep, which affects the inner width of the container in disguise, and the reduction of the inner width will greatly reduce the loading rate of the container.

5. The front plate is fixedly connected between the two front corner posts. The end plate is located on the inner side of the front corner post. The end plate has a wave structure and the wave depth is at least 25 mm, which seriously occupies the inner length of the box.

Sixth, the door hinge is usually welded with the door post by the long hinge pipe. For the 20'HC PW box type, the number of door hinges is usually six. The maintenance and replacement of the door hinge of the integral structure is cumbersome; for the 20'HC PW For the box type, the thickness of the inner door post is usually 12mm, the length of the inner door post is usually 100mm, the thickness of the outer door post is usually 10mm, and the overlap size of the outer door post on the corner piece is 5mm, and the door post is deformed. The amount is large and the strength is low; the door seal strip is specially made and the cost is high.

7. The hinge plates and ears on the door post are installed on the outer side of the square steel of the door post. The pre-installation and post-maintenance are relatively cumbersome.
