Detailed Description
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
As shown in figure 1, the light high-strength beam lower main keel comprises a keel body 1 connected with a connecting disc, connecting parts connected with the connecting disc are arranged at two ends of the keel body 1, the keel body 1 is a thin-wall square tube, the thickness of the thin-wall square tube is 3mm, edges on the keel body 1 are all in an inverted arc shape, the length of the keel body 1 is 1500mm, the height of the keel body 1 is 200mm, the width of the keel body 1 is 100mm, the ratio of the height value to the length value of the keel body 1 is 2:1, so that the structural strength of a reinforcing part can be ensured, the upper part of the keel body 1 is a bearing part, the bearing part is rectangular, the lower part of the keel body 1 is a reinforcing part, the reinforcing part is processed into a trapezoid, the length value of the upper bottom edge of the reinforcing part is the same as the value of the lower bottom edge of the bearing part, the length value of the lower bottom edge of the reinforcing, the cross-section of fretwork 2 is semi-circular, fretwork 2 can effectual reduction fossil fragments body 1's weight, and do not influence the structural strength of rib, connecting portion are including fixing the steel sheet 6 at a both ends of weighing, be fixed with outside circular steel tube on the steel sheet 6, circular steel tube is perpendicular with steel sheet 6, the outer end welding of circular steel tube has foundry practice ladle 4, the cartridge has the foundry ladle bolt 3 that runs through terminal surface about foundry ladle 4 on the foundry ladle 4, the foundry ladle bolt is used for fixing foundry ladle 4 on the connection pad, this internal diagonal angle along fossil fragments body of fossil fragments is fixed with support frame 5, support frame 5 is the X type, support frame 5 can support the inside of fossil fragments body 1, further strengthen fossil fragments body 1's intensity, the position department processing relative with the fretwork on support frame 5 has with fretwork shape assorted through-hole, the through-hole can effectual quality that reduces support frame.
