Abstract
The invention relates to an engineering mechanical vehicle body framework structure, and particularly relates to various engineering mechanical vehicle bodies. The engineering mechanical vehicle body framework structure comprises a top rear beam, a left side stand column, a right side stand column and a rear side beam. The upper end of the left side stand column is welded to the left end of the top rear beam. The upper end of the right side stand column is welded to the right end of the top rear beam. The rear side beam is arranged below the top rear beam. The left end of the rear side beam is welded to the left side stand column. The right end of the rear side beam is welded to the right side stand column. A first triangular reinforcing block is welded between the upper end of the left side stand column and the left end of the top rear beam, a second triangular reinforcing block is welded between the upper end of the right side stand column and the right end of the top rear beam, a third triangular reinforcing block is welded between the left end of the rear side beam and the left side stand column, and a fourth triangular reinforcing block is welded between the right end of the rear side beam and the right side stand column. By adding the corresponding triangular welding reinforcing blocks, the welding strength of framework profiles is ensured, and the purpose of improving the overall strength of a cab vehicle body is achieved.
Description
Technical field
The present invention relates to all kinds of Mechanical Engineering Body, as the construction applications 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 connects, because part cage construction welding position is less, soldering angle is comparatively large, and actual welding cross section is less than normal.Poor rigidity after welding, yielding, stress ratio is more concentrated.Certain influence is had to the complete vehicle structure intensity of driver's cabin and security performance.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, to provide the construction machinery vehicle body framework structure that a kind of structural strength is high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of construction machinery vehicle body framework structure, comprise top rear cross beam, left side column, right side uprights and rear-side cross member, the upper end of left side column is welded with the left end of top rear cross beam, the upper end of right side uprights is welded with the right-hand member of top rear cross beam, rear-side cross member is arranged on the below of top rear cross beam, the left end of rear-side cross member welds with left side column, the right-hand member of rear-side cross member welds with right side uprights, triangle first boss is welded with between the left end of top rear cross beam in the upper end of described left side column, triangle second boss is welded with between the right-hand member of top rear cross beam in the upper end of right side uprights, the left end of rear-side cross member with weld triangle the 3rd boss between the column of left side, the right-hand member of rear-side cross member with weld triangle the 4th boss between right side uprights.
The present invention, by increasing corresponding triangle welding boss, lengthens the welded section length between each framework section bar, reduces stress and concentrates, ensure that the weld strength between framework section bar, reach the object of the intensity that improve driver's cabin vehicle body entirety.Injury to driver when reducing when overturning or meet with junk, safety is improved.
Accompanying drawing explanation
Figure l is a kind of structural representation of the present invention.
In figure, l pushes up rear cross beam, column on the left of in the of 2,3 right side uprights, 4 rear-side cross member, 5 first bosses, 6 second bosses, 7 the 4th bosses, 8 the 3rd bosses.
Detailed description of the invention
As shown in Figure l, for a kind of construction machinery vehicle body framework structure, comprise top rear cross beam l, left side column 2, right side uprights 3 and rear-side cross member 4, the upper end of left side column 2 is welded with the left end of top rear cross beam l, the inside and outside both sides that two pieces of triangle first bosses, 5, two piece of first boss 5 is separately positioned on skeleton are welded with between the left end of top rear cross beam l in the upper end of left side column 2.The upper end of right side uprights 3 is welded with the right-hand member of top rear cross beam l, and the inside and outside both sides that two pieces of triangle second bosses, 6, two piece of second boss 6 is separately positioned on skeleton are welded with between the right-hand member of top rear cross beam l in the upper end of right side uprights 3.Rear-side cross member 4 is arranged on the below of top rear cross beam l, and the left end of rear-side cross member 4 welds with left side column 2, and the left end of rear-side cross member 4 is separately positioned on the inside and outside both sides of skeleton with welding two pieces of triangles the 3rd boss, 8, two piece of the 3rd boss 8 between left side column 2.The right-hand member of rear-side cross member 4 welds with right side uprights 3, and the right-hand member of rear-side cross member 4 is separately positioned on the inside and outside both sides of skeleton with welding two pieces of triangles the 4th boss, 7, two piece of the 4th boss 7 between right side uprights 3.
