SPIRAL DIRECT JACKING SAFETY LIFTING ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2019/024836
Kind Code:
A1
Abstract:
The invention relates to a spiral direct jacking safety lifting elevator. The spiral direct jacking safety lifting elevator comprises an elevator support guide rail frame (17), and an elevator car (18) sliding up and down along the elevator support guide rail frame (17). An elevator shaft (25) is surrounded by the elevator support guide rail frame (17). Multiple limiting sensors (19) are distributed on the elevator support guide rail frame (17) in the height direction of the elevator support guide rail frame (17), and the bottom of the elevator car (18) is connected with a spiral lifter (24) for urging lifting of the elevator car (18) and fixed on the bottom ground of the elevator shaft (25). The spiral direct jacking safety lifting elevator further comprises a controller for connecting with the limiting sensors (19) to control operation of the spiral lifter (24). The spiral direct jacking safety lifting elevator is compact in space, simplifies the elevator structure, adopts the spiral lifter to supply the lifting force from the bottom of the elevator car, so as to effectively solve the elevator car falling problem, and solve the technical difficulty of larger space size occupied by a traditional lifting mechanism.
