Abstract

The invention relates to the technical field of coal mine safety, in particular to a non-equal-wall-thickness rhombic composite structure impact energy absorption protection device, and aims to solve the problems that an existing impact energy absorption device is poor in buffering and energy absorption effect and poorer in collision resistance and impact resistance. According to the impact energy absorption protection device with the non-equal-wall-thickness rhombic composite structure, the energy absorption layer with the non-equal-wall-thickness rhombic composite structure is adopted as a main energy absorption component, and the non-equal-wall-thickness rhombic structure and the connecting arms with the non-equal-wall-thickness rhombic structure are compounded to form a composite honeycomb structure; the characteristics of small rigidity, excellent energy absorption characteristic, strong crashworthiness and good bending resistance of the non-equal-wall-thickness rhombus structure are fully utilized, and the advantages of light weight, high strength, high shear modulus, good notch resistance, good fracture resistance, high resilience toughness, stable mechanical property, excellent energy absorption capability, strong impact resistance and the like of the honeycomb structure are also exerted; the non-equal-wall-thickness rhombic composite structure energy absorption layer integrally has excellent energy absorption performance, and the structure is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of coal mine safety, in particular to an impact energy-absorbing protection device of a diamond-shaped composite structure with non-equal wall thickness. Background technique [0002] Hydraulic support is the main equipment for coal seam mining support. It not only provides safe working space for workers, but also supports and controls the roof of the working face. With the continuous development of the coal industry, the difficulty of coal mining is increasing day by day, so the reliability requirements for hydraulic supports are getting higher and higher. [0003] In the process of coal production, the hydraulic support is in a harsh working environment due to the complexity of geological conditions. During the working process of the hydraulic support, the contact conditions between the top beam of the hydraulic support and the rock wall at the top of the coal mine roadway are constantly changing, and the...
