分析了舱门在矿用救生舱设计中的重要性,并利用齿轮与齿条的啮合原理设计了舱门锁紧机构;舱门的四周对应闩板端分布有4个闩孔,闩板的伸出端呈楔形状,通过齿轮与齿条啮合带动闩板进入相应的闩孔中,在压紧力的作用下舱门处于四周压紧密封状态,确保舱门紧扣在舱体上,从而保证了舱内温度和空气免受外界直接影响;通过手柄的旋转角度判断出锁紧程度,确保了舱门对舱体的密封性能;解决了加工和安装中由于误差大而导致闩板不能对准闩孔的问题。
The importance of hatch in the design of mine rescue capsule was analyzed. The locking mechanism of hatch was designed by the meshing principle of gear and rack. Four latch holes were distributed around the corresponding latch plate, The protruding end is wedge-shaped, and the gear plate and the rack meshing drive the latch plate into the corresponding latch holes. Under the action of the clamping force, the door is in a state of tight compression and sealing around, and the door is tightly fastened on the cabin so that To ensure that the cabin temperature and air from the direct impact on the outside; through the rotation angle of the handle to determine the degree of locking, to ensure that the door of the cabin sealing performance; to solve the processing and installation due to errors caused by large error can not be on the board Pseudo-latch hole problem.
