The invention relates to lifting equipment, in particular, load handling devices, and can be used when loading and unloading long loads, such as packages of pipes.

The purpose of the invention is to provide a tight stowage during loading and unloading.

FIG. 1 shows the proposed device, a general view; in fig. 2, section A-A in FIG. fixed cheek teeth (cargo clamped); in fig. 3 -, with turned toothed cheeks (the load is released), in FIG. 4 shows a section BB in FIG. 2

The electromagnetic load gripping device contains a carrier cross-member 1, to which stands 2 with vertical grips, toothed racks 3, magnetic gripper 4 with guide 5, ferromagnetic plates 6, and electromagnetic clamps 7 are attached.

In the lower part of the rack 2 there are jagged cheeks 8 with hinged fasteners 9, retracting electromagnets 10, springs 11, springs 12, clamps 13, supporting ribs 14. Receiving electromagnets 10 are equipped with cores 15 that are through hinges 16 pivotally connected to clamps 1 To the jagged cheeks 8 are attached the stops 17.

Tacks 18 are made in conjunction with gears 19, which are hingedly connected by means of a flexible rod consisting of strips 20, additional gears 21, cables 22, through blocks 23 with a stand 2.

Tacks 18 with gear wheels 19, as well as additional gear wheels 21 are connected to guideways 5 axles 24. On axis 24, guide wheels 25 are mounted on the axle 24 at the locations of pickups 18. Clamps 13 are mounted on axis 26. Racks 2 are connected to guideways 5 axes 27. Pickups 18 cover load 28. Loads of load 28 are packed with load 28.

Load handling device operates as follows.

The load is taken in the following sequence. Traverse 1 is applied to the load. In case of contact of the captured grips 4 with a load of 28, they also include a load of 28 prt gi974

vyatsya. Switching off the electromagnetic clamps 7, lift the yoke 1 together with the uprights 2 and the toothed rails 3. In this case, the magnetic

The grippers 4 with a load 28 are at rest, and the holders 18 are automatically under the action of the forces of the gearing of the toothed racks 3 with the gears. 19, scroll and, upon exit

with engagement with them, 28 loads 29 are lying loosely lying on a row with a load of 28.

Attracted by the grip 4, the load 28 rises above the p-number of loads, and

tacks 18 under the influence of force t obsvvatsya him. At this time, the pull-in electromagnets 10 and the springs 12 are disconnected with the help of the clamps 13. The jaws 8 are closed,

which engage with the gear & the wheels 19. The gears 19 together with the pickups 18 clamp the load 28. After this, the magnetic grips can be switched off.

After this, the lifting device is lifted up and moving. to the place of unloading. When placing the load in shtabel load-lifting traverse 1 is lowered down. In time

the contact of the load with the support

include energizing electromagnets 10 that pull in the cores

15 inside, which through t g

16 is rotated with the ynms 13, releasing the jagged cheeks 8. When the clamps 13 are rotated, the springs 12 are stretched. The released jagged cheeks 8 are turned into the pillar 2 by the stretched springs 11.

Traverse 1 together with the pillar 2 continue to be lowered and the supports 18 by means of the cables 22 are automatically pulled upwards. Derived beyond the load 28, the supports 18, which are in contact with the gear wheels 19 with the vertical gear racks 3, are rotated to the upper position (Fig. 3). The guide wheels 25 enable the pick-ups 18 to smoothly

move along rack 2. The ferromagnetic plate 6 is attracted by the electromagnetic clamps 7 and locks the gripping system in the upper position (initial position).

Subsequent cycles of unloading are performed as described above.
