Description

The invention relates to the field of mechanization of the operations of storage and loading of unloading of long rolled steel and can be used in warehouses of metals of machine-building plants and at metal warehouses.

The famous multi-tiered rack containing U-shaped frame and cradles [1].

This multi-tiered rack is characterized by the inconvenience of loading and unloading, and in addition, these racks occupy large areas of storage space,

The aim of the invention is to improve the ease of loading and unloading of the rack.

To achieve this goal, a multi-tiered rack containing a U-shaped frame and lodgements is equipped with rotating frames ¹⁵ on roller bearings, a frame turning mechanism and a fixing mechanism, the frame turning mechanism being designed as movable upper carriages and counterbalance carriages interconnected by flexible connections and located inside the U-shaped frame, and the lodgements mounted on a swing frame connected pivotally with the upper carriages.

FIG. 1 schematically shows a multi-tier rack, side view; in fig. 2 - the same, end view; in fig. 3 ^: - the same, swinging frames divorced; in fig. 4 and 5 - fixation mechanism.

Tiered rack contains a U-shaped frame 1, lodgements 2. It is equipped with pivoting frames 3 on roller bearings 4, the mechanism 5 of the rotation of the frames and the mechanism 6 of fixation.

The mechanism 5 of the frame rotation is made in the form of movable upper carriages 7 and carriages counterbalances 8, interconnected by flexible connections 9 and located inside the U-shaped frame 1, and the cradle 2 is fixed on the rotary frames 3 connected pivotally to the movable upper carriages 7. Rotary frames 3 consist of two external 10 and one or more internal racks 11. The number of internal racks 11 and the pitch between them are determined by the overall dimensions and rigidity of the products that are stored on the rack. The outer 10 and inner 11 racks are interconnected by rigid horizontal links 12. In the upper part, to the side surfaces of the outer racks 10 pryam3

Lena protrusions made in the form of pins 13, which are placed in the dimensions of the vertical grooves 14. The length of the vertical grooves 14 depends on the size of the angle of inclination of the swing frames 3.

Moving the upper carriage 7 are interconnected beam 15. The carriage-counterweight 8, made in the form of a plate, is designed to ensure the fixation of the swivel frame 3 installed in the dimensions of the U-shaped frame G in a vertical position.

The fixing mechanism 6 comprises hollow concave frames 16 located in the dimensions of the lower and upper guide rollers 17. The outer shoulders of the concave frames 16 are equipped with pendulum counterweights 18. The inner shoulders of the concave frames 16 are connected by a flexible connection between themselves and the ferromagnetic plate 19 located in the pit of the warehouse floor above an electromagnet 20. In addition, the device contains the driving beams 21 and the stop 22.

The device works as follows.

In the initial position, the upper carriage 7 is raised, the swing frames 3 are fixed in the dimensions of the vertical frames of the U-shaped frame 1. In such a position, long products are stored on the cradle 2.

For stacking or removal of products from lodgments with 2 cranes of bridge or gantry type, equipped with automated load handling devices, the crane operator lowers the load handling device on the beam 15, grabs it and lifts it.

When lifting the lifting device raises the beam 15 with the upper carriage 7, the protrusions of which slide in the vertical grooves 14, and the carriage counterweights 8 release hollow concave frames 16 of the fixing mechanism 6.

Hollow concave frame 16 under the action of the pendulum counterweights 18 are deployed in the dimensions of the guide rollers 17, freeing the pivoting frames 3. Under the action of its own weight and weight of the carriages the pivoting frames 3 on the roller supports 4 move along inclined driving beams 21 to the stops 22 located in the pits of the warehouse floor .

Upon reaching the stops 22, the swivel frames 3 are stopped, occupying an inclined position in which the lengthy products placed on any lodgment 2 become accessible for grabing by suspended cranes.

When storing long items on the cradles of 2 pivot frames 3 installed in a vertical position, stacker cranes can be used to take them and move them in warehouses, as well as trucks or electric loaders.

To install the pivoting frames 3 in a vertical position, the upper carriages 7 are raised, while the pivotally connected pivoting frames 3 are raised together with them, the trunnions 13 of which are moved in the vertical grooves 14 of the U-shaped frame 1, and the roller supports 4 run around the driving beams 21. After installation of the pivot frame 3 in a vertical position include electromagnets 20, by which the concave frames 16 of the fixing mechanism 6 unfold, then the carriages-counterweights 8 are lowered onto them, which lock the concave frames 16 with their weight, and together with them and swivel frame 3 in the dimensions of the vertical frames of the U-shaped frame 1.

The invention allows rational use of warehouse space and, in addition, greatly facilitates the implementation of loading and unloading.
