Safety switch device of elevator shaft protective fence
The safety switch device comprises a bottom plate, a pedal, a rotating shaft and a connecting device, the rotating shaft is installed on one side of the bottom plate, the bottom plate is connected with the pedal through the rotating shaft, a sliding groove is formed in the top of the bottom plate, a reset spring is installed in the sliding groove, a sliding block is installed at one end of the reset spring, and the connecting device is connected with the sliding block. And a supporting rod is mounted at the top of the sliding block. According to the safety switch device of the elevator shaft protective fence, through the reset springs, when the pedal is stepped on, the pedal moves downwards, in the moving process of the pedal, the pedal drives the sliding blocks to slide forwards in the sliding grooves through the supporting rods, then the sliding blocks stretch the reset springs, and when the pedal is loosened, the reset springs contract to drive the sliding blocks to move in the opposite directions in the sliding grooves; and the pedal is reset to prevent the elevator shaft protection door from falling into the shaft due to the fact that the elevator shaft protection door is not recovered.
本发明公开了一种电梯井防护栏的安全开关装置，包括底板、踏板、转轴以及连接装置，所述底板一侧安转有转轴，且底板通过转轴与踏板连接，所述底板顶部开设有滑槽，且滑槽的内部安装有复位弹簧，所述复位弹簧的一端安装有滑块，且滑块的顶部安装有支撑杆。该电梯井防护栏的安全开关装置通过复位弹簧，当踩下踏板时，踏板向下移动，在踏板移动的过程中踏板通过支撑杆带动滑块在滑槽内向前滑动，然后滑块拉伸复位弹簧，当松开踏板时，复位弹簧收缩带动滑块在滑槽内反方向移动，对踏板进行复位，防止电梯井防护门未恢复而导致坠井事故的发生。
