The invention relates to mechanization tools for loading and unloading, in particular, to devices for unloading small metal products transported in bulk in covered wagons.

Known capture dl. unloading small metal products using a small lifting electromagnet powered by an external source. The grip is mounted on the forks of the electric forklift. An electric forklift battery may be used to power the magnet.

A disadvantage of the known grip is the need for the construction of a special cable suspension, which complicates the design of the device and increases its electrical hazard, and if the magnet is powered by the battery of the electric forklift, its operational performance is reduced due to interruptions in operation associated with charging the battery . In addition, in this case, small-sized loaders with an internal combustion engine cannot be used as the base machine.

The closest in technical essence to the proposed device is a device for lifting ferromagnetic objects, including a housing with a base made of non-magnetic material and permanent magnets placed inside the housing, moved away from the base when the load is released using a lever mechanism.

 A disadvantage of the known device is the inability to use it indoors with a limited ceiling height.

The purpose of the invention is to enable use with a small-sized loader and to increase labor productivity when working indoors with a limited ceiling height.

This goal is achieved through the use of an adjustable stop on the frame of the forklift truck and the presence of holes in the non-magnetic base of the body.

Figure 1 presents a General view of the device; figure 2 is the same side view; in Fig.Z - section aa in Fig.1; in Fig.4-section bB in Fig.Z.

The device for capturing small metal products contains a housing 1, which is suspended on three suspensions 2 to a traverse 3, worn on a fork forks and secured by a bolt 4. The housing 1 is closed from below by a copper bottom 5 with holes, and

inside it there is a permanent magnet 6 with a rod 7, on which the spring is dressed 8. On the magnet 6, stops 9 are fixed, limiting the course of the spring 8. On the cover

of the housing 1, angular levers 10 are pivotally fixed with rollers 11, which are pivotally connected to the rod by the earrings 12. A removable stop 13 is mounted on the outer frame of the forklift truck.

The device operates as follows.

The loader drives inside the covered wagon to the cargo. The driver lowering the forklift carriage lowers the housing 1 on

metal products and the magnetic field of the permanent magnet 6 pulls them to the bottom 5. After that, the loader is directed to the place of storage of goods, where the driver lifts the carriage up until the stop 13

Do not put pressure on the rollers 11 maintenance levers. The levers 10, turning through the earrings 12, pull up the rod 7. The magnetic field near the bottom 5 is weakened and the load is released. The magnet 6 rises inside the housing 1 to

until the stops 9 touch the top of the housing 1. Due to the presence of the stops 9, the spring 8 is protected against overloads. When the upward movement is stopped, the loader hydraulic system is protected

safety valve located in the loader control valve. When lowering the forklift of the forklift truck, the rollers 11 come out from under the action of the stop 13 and the spring 8 guides the magnet 6 to the bottom of the housing 1. The device is ready for the next cycle.

Claims (1)

SUMMARY OF THE INVENTION A device for gripping small metal products, comprising a housing with a non-magnetic base and movable permanent magnets mounted therein, a lever system for moving the permanent magnets inside the housing, and a suspension for mounting on a lifting device, characterized in that, in order to ensure the possibility of use with a small-sized loader and to increase labor productivity when working indoors with a limited height ceilings, it is equipped with a removable stop designed to interact with the specified system of levers and mounted on the frame of a small loader with the possibility of adjusting its position in height from the floor of the room, in the specified non-magnetic base holes are made having a size smaller than the dimensions of the lifted products.
