AUTOMATIC RESCUE APPARATUS FOR ELEVATOR

摘要

The below disclosed an automatic rescue apparatus for an elevator. The device is comprised of base (A), motor (11), input shaft (111), linkage gear (122), worm gear (12), worm screw (121), reduction gear set (13), bobbin line disk (14), and steel cable (2). The said Motor (11) connects to the input shaft (111) with thread segment (112) set up, and input shaft (111) is meshed with worm gear (12) through thread segment (112), while said worm gear (12) connects to the worm screw (121), and on the outer end of the worm screw (121) sets up linkage gear (122), meshed with the bull gear 131 of reduction gear set (13); besides, one end of the said bobbin line disk (14) is set up with gear (141), meshed with the pinion gear (132) of the reduction gear set (13), and bobbin line disk (14) is winded with steel cable (2) This device is with reasonable designing science, convenience and practicality which could make the elevator cars drop safely toward the elevator gate in the nearest floor during the malfunction, so the passengers could come out successfully.
