The invention relates to a safety elevator capable of effectively avoiding falling into a shaft. The safety elevator comprises the elevator shaft, two fixing mechanisms and a speed reducing mechanism, each fixing mechanism comprises a connecting block, an electromagnet is fixedly installed on the outer surface of each connecting block, four cross rods are fixedly installed in an inner cavity of each connecting block, and four electric telescopic rods are fixedly mounted in an inner cavity of each connecting block. According to the safety elevator capable of effectively avoiding falling into the shaft, the fixing mechanisms are connected to the left side and the right side of an elevator body through connecting columns, when the elevator decelerates to a certain speed and moves to fixing grooves formed in the front surface and the rear surface of a vertical plate, the fixing mechanisms work, two fixing plates in the fixing mechanisms move out of inner cavities of the fixing mechanisms and are inserted into the fixing grooves, springs play a role of buffering, when the fixing plates and buffer blocks move to the groove bottoms of the fixing grooves, due to limiting of the fixing grooves, the elevator body cannot continue to move downwards, and meanwhile, the electromagnet and the vertical plate attract each other, so that the auxiliary fixing effect is achieved.
本发明涉及一种有效避免坠井的安全型电梯,包括电梯井、两个固定机构和减速机构,所述固定机构包括连接块,所述连接块的外表面固定安装有电磁铁,所述连接块的内腔固定安装有数量为四个的横杆,所述连接块的内腔固定安装有数量为四个的电动伸缩杆。该有效避免坠井的安全型电梯,通过电梯本体的左右两侧通过连接柱连接有固定机构,当电梯减速到一定的速度时,并移动至竖板前后表面开设的固定槽处时,固定机构工作,使固定机构内的两个固定板从固定机构内腔移出,并插入固定槽内,弹簧起到缓冲的作用,当固定板和缓冲块移动至固定槽的槽底时,由于固定槽的限位,使电梯本体无法继续向下移动,同时电磁铁与竖板相互吸附,起到辅助固定的作用。
