A Kind Of Design In Cabin Used Mine KJYF-96/12 Movable Lifesaving Cabin

The content of this article is a kind of mine KJYF-96/12 Movable life-saving capsule, the capsule as part of the separate structure, composed of 12 quarter unit module connection, there is 2 section in transition capsule,9 section in survival capsule and 1 section equipment capsule respectively, the whole life-saving capsule provided safe and reliable shelter for miners, is the life of the coal mine worker protection equipment.The article first introduces life-saving capsule to the composition and main functions in detail, the tablet strength of paper, and the theory of plate and shell theory, the beam bending formula, respectively for transition capsule, survival strength, tank and equipment tank shell connection framework strength and antiknock property were analyzed, and the skeleton through reasonable selection and mask parameters, ensure the module performance requirements.Parameter design complete hull three-dimensional model, according to the actual circumstance of mine gas explosion in numerical analysis model is established, through the reasonable division of the grid, select the cell forms and establishing nonlinear equations to simulate analysis lay a solid foundation, through the peak load within 300 ms 0.6 MPa,1.0 MPa triangle shock waves, through the simulation analysis on wave 0.6 MPa,1.0 MPa under two kinds of load, the shell is in the process of impact stress is the most concentrated area for shell and the place such as steel frame connection, the maximum in 280 ms and 350 ms moment, 205.0 MPa,330.6 MPa. Thus, the capsule shell under two kinds of load can meet the strength requirement.The main door of capsule, strength, stiffness, sealing simulation analysis. Also within 300 ms peak load is 0.6 MPa,1.0 MPa triangle shock, two main hatch in the process of impact load under the maximum stress value appeared in the door installation location, in 280 ms and 350 ms respectively,117.1 MPa,192.0 MPa. Visible, KJYF-96/12 portable hardware capsule of coal mine main doors under wave 0.6 MPa,1.0 MPa when two kinds of load, can meet the strength requirement, the main doors stress, plastic strain and displacement results meet the practical requirements.
