Description

one

The invention relates to lifting equipment and can be used in engineering plants.

A device for lifting and

transporting unit loads in workshops, carrying a trolley connected by a monorail, connected by a lever-bearing system with a frame provided with; gripping body, electric hoist with hook and control mechanism.

However, the known device does not provide lifting and transportation of sheet materials.

In order to expand technological

The device has two spring-loaded levers that interact with the hook-mounted lugs on the frame when lifting the sheets with frame and piece goods with a hook. The trolley is equipped with pivot levers driven by electrohydraulic tappets, the rods of which are connected to the pivot levers.

Drawing 1 shows the proposed

device; in fig. 2 is the same, view along arrow A in FIG. one; in fig. 3 - device frame.

A device for lifting and transporting cargo in workshops contains a trolley 1, movable along monorail tracks, connected by a lever-hinge system 2 | with frame 3, equipped with a gripping body, 4, made in the form of rubber suckers. Inside the trolley / there is an electric hoist 5 with a hook 6 on which the lugs 7 are located. On the platform of the trolley there is a vacuum pump 8, driven by an electric motor 9. The trolley is equipped with rotary gears driven by electro-hydraulic push rods 11, the rods of which are connected to the rotary levers.

The lever-hinged system at its ends has carriages 12 sliding along the rods 13 mounted on the frame. The frame is centered by springs 14, one end of which is attached to the carriage and the other end to the rod.

On the frame there is a bracket 15 and two sub- J

a pair of lever arms 16, acting as one-1 with bosses.

 The device works as follows.

In case of cargo handling with the help of a hook 6, the frame 3 with a re-wave in the upper arms is in the upper position, where it is held by psshorotnymi levers 1O for the bushings {interlocking-swivel system 2.

When transporting the sheet, the frame with suction cups is lowered in-in, and. The flat of this hook 6 rises up so that it enters the gap between the spring-loaded levers 16. Next, turn on the electrohydraulic pushers 11, which turn the swing arms 1O counterclockwise, freeing the frame. Hook 6 then goes down with the frame, since the spring-loaded levers 16 of the latter rest on the lugs 7 of the hook 6. In the lower position, the spring-loaded levers 16 move apart, and the hook engages the bracket 15. The frame is raised, lowered and moved using an electric hoist.

In order to grip the sheet, the frame 3 with suction cups is brought to the sheet pack and lowered onto the top sheet. Then, the electric motor 9 of the vacuum pump 8 is turned on, as a result of which unloading is created in the cavity of the suction cups and the sheet is caught. Next, the sheet rises up to the required

the height and is transported to the horizontal position, which is provided by a lever with a hinged system 2.

In order to raise the frame to the upper position, the spring-loaded arms 16 are divorced and a hook with bosses is inserted under them. Then the frame is lifted up with the help of a hook, where it is held by swiveling gears using electro-hydraulic tappets.

Subject invention

Device for lifting and transport-. cargoes in shops containing a trolley transportable by monorail,

A connected lever-swivel system with a frame provided with a gripping body, an electric hoist with a hook and a control mechanism, characterized in that, in order to expand the technological capabilities of the device when lifting the sheets with the frame and piece goods with a hook, two spring-loaded levers on the frame that interact with bo by bulls mounted on a hook, and those of the dead are equipped with pivoting levers with a drive made in the form of electro-hydraulic pushers, the rods of which are connected to the pivoting levers.
