Introduces the revolving door security resilience system

Introduces the revolving door security resilience system

(Summary description)旋转门安全回弹系统撞击分析   为了消除危险区域内险情的发生,以营造小于10焦耳的人体能承受的安全冲击能量(国际经验值)为目标,博宁福田采取了三项措施:第一将展箱曲壁前端设计为可伸缩构造,首创“安全回弹装置”;第二减小制动距离;第三在出入口部位降低转速。   安全装置本身力求重量和启动力为最小,依门型尺寸需要,其设计宽度约为 400——500mm,重量约为35kg,回弹距离为250——300m

Impact analysis of rotating door safety resilience system

In order to eliminate the danger area dangers, safety impact energy to create a less than 10 joules of the human body can withstand the (international experience value) as the goal, Bonin Fukuda to take three measures: the first will show box curved wall front end design is of a telescopic structure, the first "safe rebound device"; second reduce the braking distance; third reduce speed at the entrance site.

Safety device itself to weight and the starting force is minimum, according with the type size is needed, the design width of about 400 -- 500mm, the weight is about 35kg, the rebound distance of 250 -- 300mm. Safety device of resistance in income, automatic resilience no resistance. Emergency stop when the maximum braking distance (200mm) < rebound distance (250 -- 300mm)

No safety resilience system wings automatic revolving door impact analysis

The general two wings automatic revolving door in door to run into the danger area, if a forced entry, security system that will perform the brake function, but because of inertia, door stop, there must exist certain braking distance, the remaining space is less than the width of the body, resulting in bodily injury.

In the anti clamp safety sensors first issued stop instruction, although rubber strip sensors will promptly issued second stop instruction and play a buffering role (according to unilateral rubber strip the amount of compression of high 80mm is about 50mm), but due to inertia of the door leaf is applied to the body of the force of at least 2986N, about 104 joule of energy, the force generating enough energy to cause death. The experience of safe upper limit of the human body can withstand the impact energy on the international value of 10 Joule

Safety rebound fan function description
Install the security resilience device, because of its resistance to the human body and into, leave a relaxed space, so it will not hit or crush pedestrian. The specific interaction process as shown below:
The authoritative test: with safety resilience system automatic revolving door impact energy of the human body for a maximum of 9.8 joules, slightly less than 10 joules of human bear safety collision energy, is the true meaning of the safety door.
Security proof adhesive action process
When the people in the door case to meet and turned the column, easy still broke into the door and be revolving door clamp. The rubber strip body in contact, squeezed 15 mm when the start stop brake until finally the turnstile. Plastic extrusion in under the action of stress deformation theory value of 35 mm x2=70 mm.
