FIG. one

The invention relates to lifting devices designed for tipping round flat-shaped products.

A device for turning goods is known, which contains a traverse, vertical levers mounted for movement along the traverse, at the lower ends of which rotary heads and load gripping bodies are mounted. One of the heads is equipped with a worm gearbox and handle, the other one with a spring-loaded lock.

A disadvantage of the known device is the need to perform a significant number of manual operations during the seizure and tilting of the cargo.

It is also known a device for turning cargo, which contains a traverse, stands, placed on the traverse by upper ends with the possibility of moving along it, gripping bodies, including shafts mounted horizontally at the lower ends of the struts and horizontally aligned clamps arranged with them, open from the side of the working surface, facing narrow parts of the racks.

However, the known device cannot be used for tilting flat products of a round shape, since tilting begins when the load is not fully clamped, the load is clamped during rotation and at the time of rotation 90 ° from the initial position, the flat product of circular shape (bottom blank) will slip out grabs.

The aim of the invention is to expand the range of goods being captured.

This is achieved by the fact that each gripping body includes located in one plane with the main additional clamp, made with a conical longitudinal groove, open on the side of the working surface, with the narrow part facing the stand, and arranged in a horizontal plane at an angle to the corresponding shaft of the rod, one ends which are rigidly fixed on the rotary shafts, and on the other by means of vertical axes clamps.

Figure 1 shows the proposed device with the captured product rotated 90 °, a general view; FIG. 2 is a part of the device for turning goods, plan view.

The device consists of a traverse 1, on which it is installed with the possibility of moving along the traverse during readjustment

on different diameters of the rack 2.3 products; On the rack 2 there is an electric drive consisting of a gearmotor 4 and a worm gearbox 5, which causes the shaft 6 to rotate

the gripping member 7. The shaft 6 and the gripping member 7 are moved axially in the guide 8 by means of a reversing air motor 9 and a helical gear consisting of a screw 10 and a nut 11.

0 Gripping body 7 consists of two horizontal rods 12, angled to the shaft 6, clamps 13 with a groove 14, open on the side of the working surface, mounted on vertical axes x 15 s

5 possibility of self-installation relative to the cargo perimeter 16.

The design of a diametrically opposed gripping organ 7 is similar, the shaft 6 moves in the guide

0 17 under the action of a screw transmission and an air motor.

The guide, mounted for rotation of the shaft 6 in it around the horizontal axis, is provided with a disk

5 brake preventing spontaneous rotation of the gripping body 7.

The device works as follows,

Traverse 1 is suspended from a hook of a bridge or cantilever crane. In the initial position, the pillars 2, 3 are mounted on the size of the cargo to be turned over, the gripping bodies 7 are removed, are in a horizontal position (in

5 position for seizing the load). The device is installed under the load located at the technological position and lowers until the supports 19, pillars 2, 3 contact the floor of the workshop. Air motors included

0 9, by means of screw gears, the gripping bodies 7 move to the load clamp, self-aligning along the perimeter, i.e. circumferentially, the load is clamped in the slots 14 of the clips 13.

5 Constant pressure of the gripping bodies 7 by pneumatic motors 9 selects the gaps that appear during the deflection of the load being lifted.

At a height sufficient for turning

0, the turn drive is turned on (4, 5) and the load is rotated 180 °.

When rotated 90d, the load is placed between the rods 12 and the wedge clamps 13 and the slip out of the claim 5 is locked.

After turning, the load is lowered to the same or next technological position.

The reverse of the air motors 9 is turned on, the gripping bodies 7 are retracted

Claims (1)

and devices from the load. From spontaneous rotation, the grippers 7 are blocked by the drive 4, 5 and the braking device. The invention of the device for turning goods, comprising a traverse, pillars placed on the traverse by upper ends with the ability to move along it, gripping bodies, including shafts mounted horizontally at the lower ends of the racks, and horizontally aligned clamps arranged with them, open from the working surface, about narrow racks to racks, about t, which are characterized by the fact that, in order to expand the nomenclature of captured goods, each gripping oogan includes, in the same plane as the main one, an additional clamp made with a conical longitudinal groove, open on the working surface side, turned into a narrow part to the rack, and located in a horizontal plane at an angle to the corresponding shaft of the rod, one ends of which are rigidly fixed on the rotary shafts, and on the others, clamps are fixed to the other by means of vertical axes. 1
