The invention provides a car door synchronous protection device for preventing an elevator from accidentally moving, and belongs to the technical field of elevators. The car door synchronous protection device for preventing the elevator from accidentally moving comprises a door motor which is arranged at the top of a car and used for driving the car door to be opened and closed, and is characterized in that a worm and gear speed reducer and a brake mechanism are further arranged at the top of the car, and the worm and gear speed reducer is connected with the door motor; the two braking mechanisms are connected to the two elevator guide rails located on the two sides of the lift car correspondingly, and the braking mechanisms are connected with the worm and gear speed reducer through the transmission mechanism. The braking mechanism for braking the car is synchronously controlled by the door motor for driving the car door to be opened and closed, so that when the car door is opened, the whole car is braked on the elevator guide rail, and accidental movement can be effectively prevented; meanwhile, if the elevator still moves accidentally, the cam structure of the brake mechanism can be further clamped on the elevator guide rail in the moving process, so that further accidental movement is avoided.
本发明提供了一种轿门同步式防止电梯意外移动保护装置,属于电梯技术领域。本轿门同步式防止电梯意外移动保护装置,包括设置在轿厢顶部且用于带动轿门开闭的门电机,其特征在于,轿厢顶部还设置有蜗轮蜗杆减速机和制动机构,蜗轮蜗杆减速机与门电机相连,制动机构为两个且分别连接在位于轿厢两侧的两个电梯导轨上,制动机构与蜗轮蜗杆减速机之间通过传动机构相连接。本发明由用于带动轿门开闭的门电机同步控制用于对轿厢进行制动的制动机构,使得轿门在开启时,整个轿厢制动在电梯导轨上,能够有效地防止意外移动;同时若仍发生意外移动,制动机构的凸轮结构在移动过程中能够进一步夹紧在电梯导轨上,从而避免进一步发生意外移动。
