The invention discloses a safety device for preventing an elevator door from clamping a rope, and relates to the technical field of safety devices which are not included in other categories and are used for preventing an elevator from clamping passengers. A safety device for preventing an elevator door from clamping a rope comprises a first elevator door and a second elevator door, a rope cutting-off structure is arranged on the second elevator door, and the rope cutting-off structure comprises two connecting racks, two gears, two cutters and two rotating shafts. A transmission groove, a first storage groove and a second storage groove are formed in the side, close to the first elevator door, of the second elevator door, and through cooperation of two cutters, two connecting racks, a transmission rack, two gears and a synchronous belt, the synchronous belt can drive the two gears to rotate synchronously; and the two gears can drive the two cutters to stretch out when the elevator doors are closed, so that the cutters can cut off a rope between the first elevator door and the second elevator door, the rope is prevented from being clamped between the two elevator doors, and the safety of the elevator during operation is further improved.
本发明公开了一种防电梯门夹绳的安全装置,涉及其他类目不包含的防止电梯夹住乘客的安全装置技术领域。一种防电梯门夹绳的安全装置,包括第一电梯门和第二电梯门,第二电梯门上设置有线绳切断结构,线绳切断结构包括两个连接齿条、两个齿轮、两个刀具和两个转动轴,第二电梯门靠近第一电梯门的一侧分别开设传动槽、第一收纳槽和第二收纳槽,通过两个刀具、两个连接齿条、传动齿条、两个齿轮和同步带的配合下,从而同步带能够带动两个齿轮进行同步转动,使得两个齿轮能够带动两个刀具在电梯门闭合时伸出,从而刀具能够将第一电梯门和第二电梯门之间的线绳进行切断,避免线绳卡在两个电梯门之间,进一步提高了电梯在运行时的安全性。
