Description

Technical Field

[0001] The present disclosure relates to the technical field of engineering machinery, and in particular to an engineering machinery frame mechanism and an engineering machinery. Background Art

[0002] At present, the frame of the articulated roller adopts a steel plate welded structure. This type of structure has undergone many technical iterations and has become very mature in design and process. It has the advantages of more flexible design structure and easy maintenance and replacement. However, its performance development has also encountered bottlenecks that are difficult to break through.

[0003] First, the torsional rigidity of the steel plate welded structure has certain design limitations, and it is easy to have problems of local stress concentration or insufficient overall rigidity, which will affect the overall stability of the frame, especially in the uneven road working environment, this problem is more prominent; secondly, because the frame is welded from multiple steel plates, the welds and joints are prone to become stress concentration areas, especially under complex load conditions, such as turning or driving on uneven roads, stress concentration will accelerate the fatigue failure of local structures; finally, under long-term high load conditions, fatigue cracks are prone to occur in the welds and stress concentration areas of the frame. These cracks may not be easy to detect in the early stage, but over time, crack expansion will cause sudden failure of the frame. At the same time, the fatigue life of the steel plate welded structure is greatly affected by the quality of the welds, stress concentration and residual stress. In order to ensure the safety of the frame, more frequent inspections and maintenance are usually required, which increases the operating cost of the equipment. Summary of the invention
