Abstract

The invention provides a screw elevator. The screw elevator comprises a screw power device, a lifting rope, a car and a control cabinet. Two ends of the lifting rope are connected with the screw power device and the car respectively, the control cabinet is electrically connected with the screw power device, and the screw power device comprises a counterweight, a motor, a screw and polished rods. The counterweight is connected with the lifting rope, the motor is fixed at one end of the counterweight, the polished rods are arranged at two ends of the screw respectively, the outer wall of the screw is provided with an outer thread, the motor is meshed with the screw via the outer thread to drive the counterweight to reciprocate along the screw, and the car is driven to ascend and descend by the lifting rope. The invention further provides an operating method of the screw elevator.

Description

technical field [0001] The invention belongs to the technical field of elevator design, and in particular relates to a screw elevator and an operating method thereof. Background technique [0002] In modern society, with more and more high-rise buildings, the application of elevators is becoming more and more extensive. It can be said that the elevator has become an indispensable means of transportation in people's daily life. [0003] At present, the widely used elevator is to drive the wire rope through the traction of the driving device (tractor), so that the elevator car and the counterweight do lifting motion in the elevator. However, the traction transmission mode makes the elevator have the potential danger of the elevator squatting and rushing to the top, and in recent years, accidents of the elevator falling from a high place and squatting at the bottom have occurred frequently. Contents of the invention [0004] In order to solve the above technical problems, t...
