SU22875A1 - Lifting device for cargo - Google Patents

Description

The device is intended for raising vertically a horizontal platform with weights mounted on it by systematically moving it, keeping the horizontal position, along the inclined slots of the frame.

In FIG. 1, 2 and 3 depict a view of the fixture in three projections and FIG. 4 - detail of the device.

The lifting device consists of a loading platform 1, equipped with four rollers 2, through which the screw 5 can be lowered and raised, sliding along the inclined, grooves 18, 12 formed by inclined rails 3 and 4. A screw 5 is installed between the cheeks b attached to the frame, in the racks of which the axles 13 of the axle 7 are placed. A freely rotating screw 5 is passed through the latter, the rings 8 serving to eliminate the longitudinal displacement. The screw 5 passes through the rotary axis 9 attached to the platform 111 10.

When the screw 5 is rotated, the axis 9 moves along its entire length, carried away

the platform, which, moving in inclined grooves between the strips 3 and 4, rises or falls, depending on the direction of rotation of the screw. The presence of four skids and four rollers allows the platform to maintain a stable horizontal position.
