Description

Technical Field

[0001] The invention relates to the technical field of mine protection, in particular to a protection structure based on nano energy-absorbing materials. Background Art

[0002] Nano smart energy-absorbing materials have the characteristics of rate sensitivity, network structure and self-healing. The material is very soft when not subjected to external force. Once subjected to high-speed external impact, the material quickly hardens to achieve impact protection function. After the external force is removed, the material returns to a soft state. This project will save about 50% of the cost of existing aerogel products and achieve domestic leadership. It is mainly used in aerospace, weapons, etc. in the military field, and petrochemical, rail transportation, electric power industry, underground mine rescue capsules and urban thermal pipe networks in the civilian field.

[0003] In the process of underground tunnel excavation and mining, in order to ensure the safety of operators and production equipment, the dangerous rocks on the roof of the tunnel and the mining site must be supported. One of the more advanced support forms is to anchor the dangerous rocks with anchor rods or anchor cables. When drilling anchor rod holes or anchor cable holes, the dangerous rocks must be temporarily supported at a single point. When the area of ​​dangerous rocks is large, a section of the tunnel and the mining site must be supported to ensure the safety of the operators. After the installation of the anchor rods or anchor cables is completed, they can be removed. The usual support method is to use wooden pillars and brackets for support. Hydraulic pillars used in coal mining industry can also be used for support. The use of wooden pillars and brackets requires on-site production, high labor intensity, low production efficiency, inconvenient removal, and low material reuse rate. The hydraulic pillars used in coal mines require supporting power units, hydraulic pump stations, hydraulic pipelines and other auxiliary equipment. The equipment is large and the one-time investment is high. If only a single point support is performed on the dangerous rock, it is obviously not economical. Therefore, a protective structure based on nano energy absorbing materials is needed to improve the above problems. Summary of the invention

[0086] Working principle: When in use, it is necessary to assemble the docking mechanism 3 and the supporting mechanism 4, first put the docking block 13 into the docking groove 17, then start the motor 8 to drive the screw rod 5 to rotate, thereby acting on the screw nut 6, indirectly driving the lifting rod 14 to slide upward inside the hollow rod 7 until the lifting rod 14 enters the installation groove 22.

[0087] When a collision occurs, the top nano energy-absorbing plate 31 will first absorb most of the kinetic energy of the small particles. The impact kinetic energy of the medium particles will cause the concave top plate 29 to press the concave bottom plate 27 downward, thereby squeezing the internal hollow nano energy-absorbing plate 30. The hollow nano energy-absorbing plate 30 can absorb its own energy and add its own deformation ability to reduce the impact. The impact kinetic energy of the large particles, combined with the contraction of the telescopic rod 26, squeezes the shock-absorbing spring 25 for shock absorption. At the same time, through the damping effect of the damper 15, the pull rod 32 drives the damping plate 34 to slide inside the damping sleeve 33 during the collision, so that the damping fluid in the damping sleeve 33 passes through the through holes on the surface of the damping plate 34 to prevent the energy absorption protection mechanism 1 from shaking.
