The invention relates to the field of elevators, in particular to a device for shielding a gap between a vertical lifting elevator car sill and a floor pedal based on a space cam mechanism. The invention provides an elevator door edge gap shielding device based on a space cam. The elevator door edge gap shielding device is composed of a shielding plate, a driven rotating shaft, a driven rotating shaft support, a synchronous belt, a driven belt wheel, a driving belt wheel, an electromagnet, a push rod support, a spring, a driving rotating shaft support, a driving rotating shaft, the space cam and a push rod. The device is characterized in that the device only needs to be mounted on the car of each elevator, so that the mounting labor cost is saved; the number of parts is small, synchronous belt transmission can be purchased, and machining time and labor cost are reduced; the synchronous belt transmission does not slip and is stable and reliable; the driving device only plays a motion control role and does not bear external force, so that the service life of the driving device is prolonged; the driving device can be mounted below a lift car sill, so that the space occupancy rate above the sill plane is reduced; and an automatic reset function is achieved, and accidents can be avoided when the elevator is suddenly powered off.
本发明涉及电梯领域,具体涉及到一种基于空间凸轮机构遮挡垂直升降电梯轿厢地坎与楼层踏板间缝隙的装置。本发明提供一种基于空间凸轮的电梯门边缝隙遮挡装置,由遮挡板、从动转轴、从动转轴支架、同步带、从动带轮、主动带轮、电磁铁、推杆支架、弹簧、主动转轴支架、主动转轴、空间凸轮、推杆组成。其特点在于:每部电梯只需在轿厢上安装装置,节约安装人力成本;零件数目少,同步带传动可外购,减少加工工时、工费;同步带传动不会打滑,传动稳定可靠;驱动装置本身只起运动控制作用,不承受外力,有助于其寿命的延长;可将驱动装置安装与轿厢地坎下,降低了地坎平面以上的空间占用率;具有自动复位功能,在电梯突然断电时可以避免发生事故。
