Abstract
The invention discloses a body framework structure of an engineering machine vehicle and relates to various engineering machine vehicle bodies. The body framework structure comprises a top rear cross beam, a left stand column, a right stand column and a rear lateral cross beam, wherein the upper end of the left stand column is welded with the left end of the top rear cross beam, the upper end of the right lateral stand column is welded with the right end of the top rear cross beam, the rear lateral cross beam is arranged under the top rear cross beam, the left end of the rear lateral cross beam is welded with the left lateral stand column, the right end of the rear lateral cross beam is welded with the right lateral stand column, a triangular first strengthening block is welded between the upper end of the left stand column and the left end of the top rear cross beam, a triangular second strengthening block is welded between the upper end of the right lateral stand column and the right end of the top rear cross beam, a triangular third strengthening block is welded between the left end of the rear lateral cross beam and the left lateral stand column, and a triangular fourth strengthening block is welded between the right end of the rear lateral cross beam and the right lateral stand column. By adding the corresponding triangular welding strengthening blocks, the body framework structure of the engineering machine vehicle ensures welding strength among framework section bars and achieves the aim of improving the strength of a whole cab body.
Description
Technical field
The present invention relates to all kinds of Mechanical Engineering Bodies, like the structure field of excavator vehicle body, loader vehicle body etc.
Background technology
At present, when the total welding of engineering machine vehicle driver's cabin car load skeleton connect, because part cage construction welding position is less, soldering angle was bigger, and the actual welding cross section is less than normal.Welding back poor rigidity, yielding, stress ratio is more concentrated.Complete vehicle structure intensity and security performance to driver's cabin have certain influence.
Summary of the invention
The objective of the invention is in order to overcome the deficiency of prior art, provide a kind of structural strength high Mechanical Engineering Body cage construction.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Mechanical Engineering Body cage construction; Comprise top rear cross beam, left side column, right side column and rear side crossbeam; The left end welding of the upper end of left side column and top rear cross beam, the right-hand member welding of the upper end of right side column and top rear cross beam, the rear side crossbeam is arranged on the below of top rear cross beam; The left end of rear side crossbeam and the welding of left side column; The right-hand member of rear side crossbeam and the welding of right side column, welding triangle first boss between the upper end of said left side column and the left end of top rear cross beam, welding triangle second boss between the right-hand member of the upper end of right side column and top rear cross beam; Welding triangle the 3rd boss between the left end of rear side crossbeam and the left side column, welding triangle the 4th boss between the right-hand member of rear side crossbeam and the right side column.
The present invention is through increasing corresponding triangle welding boss, and the welded section length between each framework section bar of extending reduces stress and concentrates, and has guaranteed the weld strength between framework section bar, reaches the purpose that has improved driver's cabin vehicle body integral intensity.To driver's injury, safety is improved when reduce overturning or when meeting with junk.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Among the figure, 1 top rear cross beam, 2 left side columns, 3 right side columns, 4 rear side crossbeams, 5 first bosses, 6 second bosses, 7 the 4th bosses, 8 the 3rd bosses.
The specific embodiment
As shown in Figure 1; Be a kind of Mechanical Engineering Body cage construction; Comprise top rear cross beam 1, left side column 2, right side column 3 and rear side crossbeam 4; The left end welding of the upper end of left side column 2 and top rear cross beam 1,5, two first bosses 5 of two triangle first bosses of welding are separately positioned on the inside and outside both sides of skeleton between the left end of the upper end of left side column 2 and top rear cross beam 1.The right-hand member welding of the upper end of right side column 3 and top rear cross beam 1,6, two second bosses 6 of two triangle second bosses of welding are separately positioned on the inside and outside both sides of skeleton between the right-hand member of the upper end of right side column 3 and top rear cross beam 1.Rear side crossbeam 4 is arranged on the below of top rear cross beam 1, the left end of rear side crossbeam 4 and 2 welding of left side column, and 8, two the 3rd bosses 8 of two triangle the 3rd bosses of welding are separately positioned on the inside and outside both sides of skeleton between the left end of rear side crossbeam 4 and the left side column 2.The right-hand member of rear side crossbeam 4 and 3 welding of right side column, 7, two the 4th bosses 7 of two triangle the 4th bosses of welding are separately positioned on the inside and outside both sides of skeleton between the right-hand member of rear side crossbeam 4 and the right side column 3.
