Abstract

The invention relates to the field of hoisting-and-transport devices, in particular, to car lifts. The aim of the invention is to simplify the design. The lifting platform 1 is made spiral, placed around a horizontal axis 3, mounted rotatably on supports 4, the outer end of the spiral platform mounted relative to the base 5, and a counterweight 6 is mounted on the outer surface of said spiral. The spiral platform 1 is made with a longitudinal window. On the side of its inner end, an exit bridge is mounted relative to it. 3 з.п f-ly, 2 Il,.

The invention relates to devices for lifting and moving loads, mainly vehicles.

The purpose of the invention is to simplify the design.

FIG. 1 schematically shows a device for lifting vehicles with a lower and an upper position of the vehicle, side view; in fig. 2 - the same, front view.

 The device for lifting vehicles comprises a lifting platform 1, made spiral and connected by spokes 2 to a horizontal axis 3. Axis 3 is mounted rotatably on supports 4 rigidly attached to the base 5. The outer end of the platform 1 is set tangentially to the base 5. On the outer surface the helix mounted counterweight 6. The inner end of the pad 1 is made with a longitudinal window 7, equipped with transverse stiffening elements 8. On the side of the inner end of the pad 1, the outgoing bridge 9 is fixed, to As shown by the dotted line in FIG. 1 and 2, the Exit bridge 9 is located tangentially. To the inner end of the platform j, equipped with a stop 10.

On the ground 1 placed the vehicle 11.

Device for lifting vehicles works as follows.

In a state of stable equilibrium, platform 1 is located with the outer end located at the base 5, due to the slight static moment applied to this outer end. At the entrance of the vehicle 11 to the outer end of the platform 1, the latter is practically not subject to angular movement, due to its own significant moment i inertia. After entering the platform 1, the vehicle continues to drift at a low speed. As a result of the actuation of the circumferential force of the driving wheels of the vehicle 11 and the displacement of its center of mass to the right relative to the vertical axis of the device, the platform 1 rotates

on s.-roll. L BOKiiyv axis 3, while the vehicle 11 is moving in a parallel and vertical direction

direction until BityTpBHHero reaches the end of platform 1, which, for any turn phrase, remains in stable equilibrium due to the position of the transport center (where

11 below axis 3. In the event of a sudden stop of the engine, the vehicle 11 and platform 1 are in a stable, stationary position.

After lifting the vehicle 11, for example, an inspection can be carried out and its lower part is removed through the through window 7. Then, when the vehicle is moving 11 in reverse, the reverse occurs

rotation of pad 1, as a result

which the vehicle drops to ground level 5.

If necessary, after lifting to a height H vehicle

11 may move from the platform 1 to the side on the exit bridge 9. After that, the device is ready to lift another vehicle.

Claims (3)
