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.
