电动悬挂式实验室大门改造设计

摘要本文主要任务是在现有实验室大门基础上进行改造设计，实际实验室大门要求安全、防雨、防腐蚀，外观大方，操作简单方便，易于维修。

根据上述要求，本人进行实地考察，查阅相关资料，进行详细论证，结构方案设计、具体零部件设计、电气控制系统设计、机构强度校核。本文设计的实验室大门采用悬挂式，使用钢丝绳来拉动门体在导轨上移动。采用蜗轮蜗杆减速，电机驱动，设计有相应的电气控制系统。配有挡雨板、门铃等辅助设施。最后，对其中的关键部件进行强度和刚度校核。本次设计改进，实现一部电机完成门的开启和关闭，保证了门在外界复杂多变环境下的正常使用。同时，门的可靠度也得到了保证。63513

Title The transformation of laboratory electric door

Abstract This task of this paper is the renovation design of laboratory door based on existing laboratory door. The actual lab door requires meeting the needs of security, weatherproof, corrosion, elegant appearance, simple operation and easy maintenance.

According to the above requirements, I make an on-the-spot investigation , refer to relevant data, conduct a detailed feasibility studies, structural design, detailed component design, electrical control system design, mechanical strength check. This design uses the hanging laboratory door and rope is used to pull the door on the rail movement. Using worm reducer, motor drives, a corresponding electrical control system is designed. The door is equipped with flashings, doorbell and other auxiliary facilities. Finally, one of the key components of the strength and rigidity check is conducted. The design achieve the effect opening and closing the door with one complete motor and ensure that the door works normally in complex environments. Meanwhile, the reliability of the door has also been guaranteed.
