Abstract
A construction machinery vehicle body framework structure relates to various construction machinery vehicle bodies, and comprises a rear top cross beam, a left side vertical column, a right side vertical column and a rear side cross beam, wherein the upper end of the left side vertical column is welded with the left end of the rear top cross beam; the upper end of the right side vertical column is welded with the right end of the rear top cross beam; the rear side cross beam is arranged below the rear top cross beam; the left end of the rear side cross beam is welded with the left side vertical column; the right end of the rear side cross beam is welded with the right side vertical column; a first triangular reinforced block is welded between the upper end of the left side vertical column and the left end of the rear top cross beam; a second triangular reinforced block is welded between the upper end of the right side vertical column and the right end of the rear top cross beam; a third triangular reinforced block is welded between the left end of the rear side cross beam and the left side vertical column; and a fourth triangular reinforced block is arranged between the right end of the rear side cross beam and the right side vertical column. In the construction machinery vehicle body framework structure, by adding the corresponding triangular reinforced blocks, the welding strength of framework section bars is ensured, and the aim of improving the integral strength of a cab body can be achieved.
Description
Technical field
The utility model relates to all kinds of Mechanical Engineering Bodies, as the structure field of excavating machine vehicle body, loader vehicle body etc.
Background technology
At present, when the total welding of engineering machine vehicle operator's compartment car load skeleton connect, because part skeleton structure weld is less, soldering angle was bigger, and the actual welding cross section is less than normal.Welding back poor rigidity, yielding, stress amplitude ratio is more concentrated.Complete vehicle structure intensity and safety performance to operator's compartment have certain influence.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of structural strength high Mechanical Engineering Body skeleton structure.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Mechanical Engineering Body skeleton structure, comprise the top after cross member, the left side column, right side column and rear side crossbeam, the left end welding of the upper end of left side column and top after cross member, the right-hand member welding of the upper end of right side column and top after cross member, the rear side crossbeam is arranged on the below of top after cross member, 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 described left side column and the left end of top after cross member, welding triangle second boss between the right-hand member of the upper end of right side column and top after cross member, 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 utility model is by increasing corresponding triangle welding boss, and the welded section length between each framework section bar of extending reduces stress concentration, has guaranteed the weld strength between framework section bar, reaches the purpose that has improved operator's compartment vehicle body integral intensity.To the injury of chaufeur, 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 utility model.
Among the figure, 1 top after cross member, 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 skeleton structure, comprise top after cross member 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 after cross member 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 upper end of left side column 2 and the left end of top after cross member 1.The right-hand member welding of the upper end of right side column 3 and top after cross member 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 after cross member 1.Rear side crossbeam 4 is arranged on the below of top after cross member 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.
