ABSTRACT
The caving hydraulic support is one of the most indispensable support equipment in the full mechanization coal mining face. Its performance will impact the safety of prehensive mechanization coal mining face and the staff.
Initialization parameters for the processing and two-dimensional CAD design drawing is the main ways in the traditional design process of the caving hydraulic support. However, this article will connect the design of the caving hydraulic supports of support cover type with the optimization of the 4 linkage mechanisms, three-dimensional modeling and assembly and the motion simulation and analysis and research so as to reduce the production cycle R & D costs and improve quality and production efficiency.
The focus of this article’s research is that utilizing Pro/ENGINEER Wildfire three-dimensional modeling based on the optimal design of the caving hydraulic supports of support cover type (4 linkage mechanisms). Then, utilizing motion simulation module (MECHANISM) to achieve the realization of hydraulic support bracket cover up, down and pick column, beam loading process of the caving dynamic simulation and analysis. The results show that the results of optimum design, the establishment of the model and the simulation parameter settings correct, no movement to interfere in the region, the top beam similar to the front of the track in line with the requirements of double-twisted wire.
