Problems solved by technology

[0002] Usually the existing elevators mostly use the hoist to drive the cable to pull the car to realize the purpose of car lifting, but there are certain defects in this elevator, such as because the hoist will be placed so it will take up a large space, and because the installation of the hoist The location is far away from the car, so when the car stops suddenly due to power failure or other accidents, the people in the car cannot save themselves in the car, which is relatively passive and likely to cause other unexpected dangers. The danger of the car being out of control due to the cable being pulled

Embodiment Construction

[0013] refer to figure 1 As shown in Fig. 3, a spiral-guided floating magnetic vertical motor lifter includes a car 1, a lifting mechanism fixedly connected to the car 1, and a control circuit for driving the lifting mechanism. The threaded helical conduit 2 and the linear motor formed by the loop 3 that is threaded outside the helical conduit 2 and can run longitudinally along the floating magnetic guide rail and has a single winding coil, and the passive positioning helical guide disc 4 screwed in the helical conduit 2, The spiral conduit 2 is provided with a power export groove 21 along the axial direction, and the guide plate 4 is provided with external threads, which can be screwed with the spiral conduit 2. Three rolling guide wheels 42 are embedded on the surface of the external threads, and the guide wheels 42 are slightly higher. On the surface of the external thread and in contact with the internal thread of the spiral conduit 2, the two ends of the guide plate 4 are...

Abstract

The invention relates to a screw guide magnetic floating vertical motor lifter, which comprises a compartment, a lifting device connected to the compartment and a control circuit driving the lifting device, wherein said lifting device comprises a straight motor formed by screw tube and clamp ring, and a guide disk; the straight motor drives the compartment; the guide disk inside the screw tube and connected to the compartment is screwed lifted with the screw tube; since the compartment is near to the lifting device, when the compartment is not powered or abnormal, people can control the brake disc inside the compartment to slowly lift down the guide disc along the screw tube to the safe position to be rescued.

Description

technical field [0001] The invention relates to a lifter, in particular to a spiral-guiding floating magnetic vertical motor lifter. Background technique [0002] Usually the existing elevators mostly use the hoist to drive the cable to pull the car to realize the purpose of car lifting, but there are certain defects in this elevator, such as because the hoist will be placed so it will take up a large space, and because the installation of the hoist The location is far away from the car, so when the car stops suddenly due to power failure or other accidents, people in the car cannot save themselves in the car, which is relatively passive and easily causes other unexpected dangers. There is a danger of the car being out of control due to the cable being pulled off. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a spiral-guided floating magnetic vertical motor lifter with simple structure, reliable p...
