[0005] Preferably, the shapes of the main beam hollow groove and the end beam hollow groove are composed of a rectangle on top and an isosceles trapezoid on the bottom, the length of the rectangle is equal to the length of the base of the isosceles trapezoid close to the rectangle, and the length of the other base of the isosceles trapezoid is smaller than the length of the rectangle.

[0006] Further preferably, the plug-in plate is removed from the end beam connecting plate when the end beam hollow groove is processed.

[0007] Further preferably, the fixed connection method between the plug-in plate and the main beam connecting plate outside the main beam hollow groove is welding.

[0008] Further preferably, the plug-in plate and the end beam hollow groove are fixedly connected by spot welding, and the main beam connecting plate and the end beam connecting plate are fixedly connected by flanges and bolts.

[0009] Compared with the prior art, the advantages of the utility model are:

[0010] 1) The plate material of the old traditional hanging structure is optimized. By using the plate deducted from the middle of the end beam connecting plate to the main beam connecting plate, the hollow plate in the middle of the main beam connecting plate can be stored and reused, resulting in secondary utilization, thereby saving costs invisibly. The main beam connecting plate is also changed from the original milling surface reserve thickness to the actual contact surface thickness, saving the plate thickness cost;

[0011] 2) Improve production efficiency: Changed the traditional machining method of milling the hook groove on both sides of the main beam hanging plate and the upper two sides of the end beam connecting plate, and reduced the machining process of the main end beam connecting plate;

[0012] 3) Improved installation strength: The old traditional structure has a small contact surface of the main end beam hanging plate, while the structure of the utility model increases the contact area of ​​the main end beam connecting plate and increases the connection strength.
