The invention relates to the field of lifting devices, mainly for lifting vehicles.

The purpose of the invention is to simplify operation by providing a drive rotation of the screw plane by the wheels of the vehicle.

FIG. 1 shows a schematic elevator for vehicles, side view; in fig. 2 is a view A of FIG. one; in fig. 3 - section B — B in FIG. 2; in fig. 4 is a view of B in FIG. 3; in fig. 5 - section G - G in FIG. four; in fig. 6 shows a section D —D in FIG. four.

The elevator for vehicles contains a screw plane 1 rigidly mounted on a vertical rotary axis 2, which is mounted on the base 3 with the help of thrust bearings 4. Parallel to the axis 2 on the base 3, a guide 5 is fixedly mounted.

On the latter, cylindrical sections 6 and 7 are formed in the upper and lower parts, respectively, and mounted on the sleeve 8 with the possibility of longitudinal vertical movement of the movement limiter 9 installed across the helical plane 1. In addition, on the guide 5, longitudinal protrusion 10 facing the screw plane 1, and the upper cylindrical section 6 is provided with a radial stop 11 under the stop 9 movement. This radial stop 11 is offset relative to the longitudinal protrusion 10 in the radial direction at an angle of 90 ° (Fig. 3). At the radial stop 11, the guide 5 is equipped with another longitudinal protrusion 12 parallel to the protrusion 10. Accordingly, the protrusion 12 is offset relative to the protrusion 10 in the radial direction by an angle of 90 °. The sleeve 8 of the stopper 9 movement made with three longitudinal grooves 13 (Fig. 5) under the longitudinal protrusions 10 and 12 of the guide 5, and these grooves 13 are also offset relative to each other in the radial direction through an angle of 90 °. Between the lower ends of both longitudinal projections 1.0 and 12, the cylindrical section 7 of the lower part of the guide 5 is provided with a reflector 14, made along a helical line (Fig. 4). The reflector 14 is directed at its upper end to the longitudinal protrusion 12 of the guide 5, and its lower end to the other longitudinal protrusion 10. The lower surface of the sleeve 8, facing the reflector 14, is also made along a helical line (Fig. 4). The reflector 14 is made along a helical line with a central angle of 270 ° in the radial direction (Fig. 6). At the lower end of the reflector 14, which is directed toward the longitudinal protrusion 10, on the base 3 a vertical stop 15 is rigidly mounted, parallel to the longitudinal protrusion 10. U

The upper part of the screw plane 1 is located on the exit bridge 16. On the screw plane 1 there is a liftable vehicle 17, for example a car (Fig. 1 and 2, shown in the lower and upper positions, respectively, at the beginning and end of the lift).

Lift for vehicles works as follows.

In the initial position, the limiter 9 movement is located between the turns of the screw plane 1 in its lower part. The vehicle 17 leaves the screw plane 1 and rests against the stop 9 of movement, which is kept from rotating in the horizontal plane by a vertical stop 15. Under the action of the circumferential force of the driving wheels of the vehicle 17, the screw plane 1 with axis 2 starts to rotate in the thrust bearing 4, providing a plane-parallel moving the vehicle 17 in the vertical direction. At the same time, the movement limiter 9 on the sleeve 8 moves vertically up first along the vertical stop 15, and then the sleeve 8 is mounted with its longitudinal grooves 13 on the longitudinal projections 10 and 12 of the guide 5, which keep the sleeve 8 from radial rotation. When the vehicle 17 reaches the top position, the sleeve 8 hits the cylindrical section 6 of the guide 5 and comes down from the longitudinal projections 10 and 12. Under the action of force from the vehicle 17, the movement limiter 9 rotates on the sleeve 8 relative to the guide 5 at an angle of 90 ° (FIG. 3) until it comes into contact with the radial stop 11. After this, the vehicle 17 moves freely from the helical plane 1 to the exit bridge 16.

Upon reaching the stop 9 of the movement of the radial stop 11, the longitudinal protrusions 10 and 12 of the guide 5 are aligned with the other longitudinal grooves of the sleeve 8, with the result that this sleeve together with the stop 9 of movement extended beyond the screw plane 1 under the action of its own weight moves along the longitudinal projections 10 and 12 vertically down. Having reached the lower cylindrical section 7 of the guide 5, the sleeve 8 comes off from the longitudinal projections 10 and 12 (Fig. 4), and its lower surface is mounted on the screw reflector 14 and due to the action of its own weight, it slides in the radial direction through the angle of 270 ° before contact with the vertical stop 15. Thus, for the cycle of operation, the sleeve 8 makes a full rotation around the guide 5 by 360 °, and the movement limiter 9 returns at the bottom of the direction5

5 to its original position, being established between the turns of the helical plane 1.
