MAGNETIC-MECHANICAL RAPID DEVICE

The invention relates to a lifting and transport equipment, namely to lifting devices, and can be used in loading and unloading and transporting long loads, such as rolls.

The magnetic-mechanical gripping devices are known, which contain a yoke suspended from an overhead crane with pickups and movable lifting electromagnets {11.

However, such a magnetic-mechanical cargo handling: the device cannot be loaded and unloaded packages of pipes laid close together.

The purpose of the invention is to ensure the loading and unloading of packages of pipes laid close to vehicles.

This is achieved by the fact that, at the ends of the crosshead, the folding vertical vertical posts that are displaced relative to each other are hinged, which have guide cuts and rollers, and the pickups are movably mounted in the uprights Electromagnets are associated with the rams of the power cylinders for their raising and lowering, also attached to the traverse.

FIG. Figure 1 shows the device in its initial position (the pillars and supports are extended, and the electromagnets are in the upper position); in fig. 2 - the same, before lowering on the load (racks and grab slips to the size of the diameter of the load, electromagnet in the lower position); in fig. 3 - the moment of the seizure of cargo (the device with folded poles and pickups and magnet pushed on the package of tubes); in fig. 4 - the moment of lifting the load (the package of pipes is lifted by electromagnets, the legs and supports are folded); in fig. 5 installation of the load (the racks and supports are extended, the electromagnet with the load lifts to the initial position); in fig. 6 - securing the load (racks are moved apart, the supports are closed under the load, the load is lowered onto the supports by electromagnets).

The proposed magnetic-mechanical gripping device consists of a load-carrying bar 1, suspended on an overhead crane. Traverse 1 is made in the form of a tank in which the working fluid used to operate the hydraulic actuators is placed, at the ends of the crosspiece 1 of the hinge are fixed, displaced relative to each other, four folding vertical pillars 2 in which retractable pickups 3 are placed.

3

racks 2 have guide cuts 4 and ustan (the rollers 5, which extend the grippers 3 along the radius, the end of each pick-up is pivotally connected to the rod of the power cylinder 6. The movable lifting electromagnets 7 are mounted directly on the yoke 1 and are moved in a vertical plane by lifting hydraulic cylinders 8. Traverse 1 also has all the mechanisms of hydraulic drives installed: electric motor, hydraulic pump, control valves, pipelines, etc. (not shown in the drawings). The hydraulic drive is carried out remotely from the crane driver's cab.

Magnetic-mechanical gripping device operates as follows.

Before unloading, for example, bundles of pipes from gullets, the gripping device is suspended on the hook of an overhead crane and is set to its original position, in which the vertical posts 2 and the tacks 3 located on the yoke 1 are moved apart and the lifting electromagnets 7 are in the upper position the position of the device is brought to the place of unloading of goods. The device is then prepared for lowering onto a package of pipes, for which the vertical posts 2 and the supports 3, with the help of the power cylinders 6, are folded up to the size of the cargo diameter, and the electromagnets 7 extend into. lower position with the help of power hydraulic cylinders 8. The device with the legs 2 folded and the arms 3 with the electromagnets extended 7 are lowered onto the tube package, including electromagnets 7 which attract the load. Next, the device with the tube package is lifted, while the supports 2 and the supports 3 are folded and the load is set, for which the supports 2 and the supports 3 push the power cylinders 6 and the electromagnets 7 with the attracted package of tubes lift the power cylinders 8. After this, the load is fixed, for which with the help of cylinder 6, the clamps 3 are closed under the load, which is then lowered onto the clamps 3 by the electromagnet 7, after which

cargo is transported to a given place. The loading of the tube packages is carried out in the reverse order.

The proposed magnetic-mechanical gripping device provides loading and unloading of packages of pipes laid close together, and can also be used to lift out of pockets and transport any steel long products not connected to the package (i.e., Russia), which

Q is very important in the production of long products at metallurgical plants, since it does not require the replacement of one device with another. The use of the proposed device allows to mechanize hard work, to expand the area

g use, increase labor productivity and safety of the device closure. A new device, as an event on a new technology, is included in the OCD plan of the plant and a decision is made to develop a sketchy project for this device.
