Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.

As shown in fig. 1-3, the non-counterweight forced drive elevator is disposed in an elevator shaft 1, and includes a car 2 and a car drive device 3, a pair of guide rails 11 is symmetrically disposed on an inner wall of the elevator shaft 1, a plurality of rail wheels 110 are fixed on the guide rails 11 and spaced from each other, and the car drive device 3 is disposed on a top of the car 2 and fixedly connected to the car 2;

the car driving device 3 comprises a shell 31 and an outer rotor motor 32 arranged in the shell 31, a spiral track 33 is annularly arranged on the outer wall of the shell 31, the spiral track 33 is positioned between a pair of guide tracks 11 and matched with the track wheel 110, and the outer rotor motor 32 is fixedly arranged in the shell 31 and drives the shell 31 to rotate. The outer casing 312 of the outer rotor motor 32 is connected with the casing 31, when the outer rotor motor 32 operates, the outer casing 312 of the outer rotor motor 32 rotates, the motor shaft 320 keeps static, thus, under the driving of the outer rotor motor 32, the casing 31 rotates, further, the spiral track 33 rotates, under the action of the track wheels 110, the casing 31 rotates and moves up and down along the vertical direction, namely, the spiral ascending motion, and because the motor shaft 320 of the outer rotor motor 32 connected with the car 2 is fixed and does not rotate, the car 2 only does reciprocating motion in the linear direction, the reliable transportation of passengers is completed, the structure is simplified, the installation and the maintenance are convenient and rapid, even if power is cut off accidentally, the spiral track 33 can still be clamped between the track wheels 110 of the pair of guide tracks 11 in a matching mode, the falling accident cannot happen, the safety performance is high, and the safety of passengers is effectively guaranteed.

The pitch of the spiral track 33 is the same as the distance between two adjacent track wheels 110 on the same guide track 11. The spiral track 33 can be ensured to be always matched with the track wheel 110 when the spiral rises; the spiral track 33 is wound at least two times on the outer wall of the shell 31, and the number of the track wheels 110 on the pair of guide tracks 11 in the matching state with the spiral track 33 is at least four, so that enough track wheels 110 are matched with the spiral track 33 at any position of the elevator shaft 1 of the car driving device, the weight of the shell 31 and the car 2 is reliably supported, and the running safety is improved.

The shell 31 comprises an inner shell 311 and an outer shell 312, the outer shell 312 is sleeved outside the inner shell 311, the top of the inner wall of the outer shell 312 is fixedly connected with the top of the outer wall of the inner shell 311, and the bottom of the inner wall of the outer shell 312 is fixedly connected with the bottom of the outer wall of the inner shell 311;
