Description

This invention relates to storage equipment, in particular, to storage racks made of metal profiles for storing and storing products. The technical solution can be used in the construction of shelving and in the technology of their manufacture.

Warehouse racks are known, each of which contains g-shaped racks in cross section, in the walls of which there are shaped holes located along the height of each rack with a narrowed lower part, longitudinal and transverse beams installed on racks in the tier. On the outer surface of each beam, hooks are made located in the figured holes of the racks (MKF Storage Rack, Yandex, Metal-Plant, MKF Storage Racks, 2008. MKF Series Storage Racks, Yandex, metalcity, 05/30/2014).

Known warehouse rack containing l-shaped in cross-section of the rack, the walls of which are arranged along the height of the rack shaped holes with a narrowed lower part, mounted on racks in the tier of longitudinal and transverse beams, on the outer surface of each of which are made hooks located in the figured rack openings (MKF Storage Rack, Yandex, Metal Plant, MKF Storage Racks, 2008). The disadvantage of this rack is its unsatisfactory bearing capacity and strength, associated with the need to increase metal consumption and design complexity in case of increasing the bearing capacity of the rack.

Known rack containing racks and mounted on them with fastening elements of the beam. The fasteners are hooks that are rigidly connected to the beams or made integral with them. Hooks are located in the figured holes of the racks, with each fastening element having a head, a neck made with it, located in the vertical groove of the rack hole, and each figured hole has an upper semicircular part and a lower part in the form of a groove (Shelf made from profile. prefabricated. Beam fastening. Safe-buy.ru/ racks, 2019. Sobr-metal-stel-metal. PMet.ru. Yandex.ru, 2019).

Known rack containing racks with longitudinal slots and holes, while the holes of the rack and the flange of the square made in the form of a rectangular trapezoid, the bottom of the square of the square complemented by an elongated groove on the vertical side of the trapezoid, and each of the connecting elements is made in the form of a separate retainer with the possibility of interaction with the holes racks and a square and is formed by two plates rotated relative to one another, one of which has a groove longer than the width by the thickness of the square (RU 8220 U1, 11.16.1998)

It is known to connect a collapsible rack, in which with the aim of increasing stability and reliability, simplifying the connection of elements of the rack, it contains vertical racks and brackets. The vertical rack is equipped on the front side with through grooves, and the brackets are equipped with L-shaped downward-curved fasteners and fixed with their rear side on the vertical rack, while the through grooves on the vertical rack are made in the form of rhombic holes having a guide and a working surface, and the guide surface is made at an angle of up to 45 degrees, and the working surface is at an angle of up to 90 degrees relative to the side surface of the vertical rack (RU 2347516 C1, 02.27.2009).

Shelving systems are also known, each of which contains racks with holes and beam hooks located in the holes (ES 2157695 A1, 08/16/2001. US 5036778 A, 08/06/1991. EP 0425861 A, 05/08/1991. US 4821649 A, 04/18/1989. US 4607576 A, 08.28.1986. US 4549665 A, 10.29.1985. GB 2122880 A, 01.25.1984. FR 2464676 A, 03.20.1981. US 4148263 A, 04.10.1979. US 359234 A, 07.13.1971. ITBS 910060 A1, 12/08/1992. IT 1236373 02.25.1993).

A well-known analogue to the technical solution presented in this description is a rack containing profiled L-shaped cross-sections of the rack and longitudinal and transverse beams connected to them by hooks, each beam has a horizontal stiffener in the form of a shelf under the shelving, and a vertical stiffener , in which at least one hook is rigidly fixed, figured holes located at the height of the rack are made in the walls of each rack, each of which has an upper rounded part, and also a groove communicated with the rounded part of the hole and extending downward from the rounded part, with in each groove there is a neck of the hook, which has a round head located on the outside of the rack (Yandex. Sobr-metal-stel-metal-pr-13kreplenie-balok-1024x1024. 08.30.2019).

In this analogue, due to technological errors, gaps in the horizontal plane between the neck of the hooks and the edges of the grooves of the figured holes are not completely selected, which leads to incomplete working contacts of the hooks of some beams with racks and to overloads of the hooks of other beams. As a result, backlashes are formed between the uprights and one of the beams and stress concentration on the hooks of other beams. At the same time, the estimated load-bearing capacity of the rack in the indicated conditions for its use is practically not achieved, and reliability is reduced.

Of the known closest to the technical solution presented in this description is a storage rack containing l-shaped in cross-section of the rack, in the walls of which are made shaped holes located along the height of the rack with a narrowed lower part, longitudinal and transverse beams installed on the racks in the tier, on the outer surface of each of which is made of hooks in the form of a pair of hooks located in the figured holes of the uprights, and flooring located on the beams, characterized in that the upper part of each beam is stepwise curved in the vertical and horizontal planes with the formation of an upper stiffener with a lower step, on of which the flooring is located, and the lower part of each beam has a lower stiffener bent into the beam at an oblique angle, while the legs of the hooks with interference are located in the holes of the racks so that in the working position the hooks are firmly pressed against each other by their legs. The hooks are located between the upper and lower stiffeners of the beam, each hook is made of a pair of horizontally oriented flat hooks protruding above the front surface of the beam, mirrored relative to each other, and the hook legs are located in the lower narrowed part of the figured hole (RU 162912 U1, 27.06 .2016 - prototype).

The prototype has a relatively complex structure due to the fact that a pair of hooks of complex shape are made at each end of the beam, while each hook of the pair is located relative to the other hook so that the legs of the hooks are located in the lower narrowed part of the figured hole and are tightly pressed against each other.

Due to manufacturing errors, the legs of the hooks are not always tightly located in the holes of the uprights in the position where the hooks are pressed firmly against each other with their legs. As a result, there is a danger when the load from the load on the rack is concentrated on one hook twice as much as the calculated one. In this case, there is a danger of a cut of the hook, which reduces the reliability of the rack.

The technical result presented in this description of the rack is to increase the reliability of the rack.

The technical result was obtained by the first version of the rack, containing g-shaped cross-sectional racks, longitudinal and transverse beams connected to them by hooks, each beam has a horizontal stiffener under the flooring of the rack and a vertical stiffener, at each end of which there is at least one a hook, while in the walls of each rack there are made figured holes located along its height, each of which has an upper round part and a conical groove communicated with it extending downward from the round part, in which a neck of the hook has an outer head located on the outside of the rack in this case, in the horizontal plane, each end of each beam is beveled to the middle of the beam, and each hook has an inner head and a neck made integral with the external head, the neck of the hook is pressed into the hole of the vertical stiffener of the beam, the diameter of the neck of the hook is greater than the width of the groove in it bottom, conical groove tilted in st the angle of the strut at an angle α within α = 2.0-3.0 °, located between the vertical axis of symmetry of the round hole and the axis of symmetry of the groove, the said bevel of each beam is formed by a downward flanging in contact with the flanging of the adjacent beam, each wall of the rack is located Contrary between the surface of the vertical stiffening beam and the inner surface of the outer head of the hook, for which the gap between these surfaces is less than the thickness of the rack wall.

Each conical groove of the figured hole of the rack is made in the form of an isosceles truncated isosceles trapezoid.

The bevels formed by the flanges of adjacent shelving beams are made at an angle of 45 ° to the longitudinal axes of these beams.

The diameter of the neck of the hook is greater than the width of the groove in its lower part by the value D3 = (1.1-1.15) L1, where D3 is the diameter of the neck, and L1 is the width of the groove in its lower part, and L1 depends on the height S of the conical groove limits L1 = (0.4-0.5) S.

A gap is formed between the neck of the hook and the end of the conical groove.

The technical result was obtained by the second version of the rack, containing g-shaped racks in the cross section, longitudinal and transverse beams connected to them by hooks, each beam has a horizontal stiffener for the shelving and a vertical stiffener, at each end of which there is at least one a hook, while in the walls of each rack there are made figured holes located along its height, each of which has an upper round part and a conical groove communicated with it extending downward from the round part, in which a neck of the hook has an outer head located on the outside of the rack in this case, in the horizontal plane, each end of each beam is beveled to the middle of the beam, and each hook has an inner head and a neck made integral with the external head, the neck of the hook is pressed into the hole of the vertical stiffener of the beam, the diameter of the neck of the hook is greater than the width of the groove in it lower part, the longitudinal axis of the conical the base is located on the vertical axis of symmetry of the round part of the figured hole, the said bevel of each beam is formed by a flange in contact with the flange of the adjacent beam, each wall of the strut is opposed between the surface of the vertical stiffener of the beam and the inner surface of the outer head of the hook, for which the gap between these surfaces is less than the thickness rack walls.

Each conical groove of the figured hole of the rack is made in the form of a truncated isosceles trapezoid.

The bevels formed by the flanges of adjacent shelving beams are made at an angle of 45 ° to the longitudinal axes of these beams.

The diameter of the neck of the hook is greater than the width of the groove in its lower part by the value D3 = (1.1-1.15) L1, where D3 is the diameter of the neck, and L1 is the width of the groove in its lower part, and L1 depends on the height S of the conical groove limits L1 = (0.4-0.5) S.

A gap is formed between the neck of the hook and the end of the conical groove.

The essence of the rack is disclosed in the description below and in the drawings, which show, as one example of the implementation of the rack with two hooks at each end of each beam. Such a rack is designed to store heavy loads on it. For a rack with a lower bearing load, beams are used, at the ends of which one hook is fixed.

In FIG. 1 shows a rack with one tier of beams, front view.

In FIG. 2 shows the rack in a top view along arrow A in FIG. 1.

In FIG. 3 - the relative position of the curly holes of the rack and the hooks of the beam.

In FIG. 4 is a section bb in FIG. 3.

In FIG. 5 is a section GG in FIG. 4

In FIG. 6 - shaped hole rack with an inclined conical groove.

In FIG. 7 - the location of the neck of the hook in an inclined conical groove.

In FIG. 8 - a shaped hole with a conical groove, the axis of symmetry of which is located on the vertical axis of symmetry of the upper circular part of the hole (second version of the shaped hole).

In FIG. 9 - connection of the rack with the beam of the rack in the context of the rack and beam along the axis of the necks of the hooks.

In FIG. 10 is a view along arrow D in FIG. 9.

Each variant of the rack described below contains predominantly l-shaped sections made of profiles in the cross section of the rack 1 (Fig. 1, 2), in each wall of each rack along its entire height, figured holes are made. Each shaped hole is formed by the upper circular part 2 (Fig. 6) and extending downward from the circular part and connected with it by a conical groove 3. Each conical groove 3 of the shaped hole of the rack is made in the form of an isosceles truncated trapezoid.

Each groove 3 of the rack holes is intended for the location in it of the neck 4 of the hook 5 (Fig. 4). The diameter D3 of the neck 4 of the hook is larger than the width of the groove 3 in its lower part (Fig. 6), while D3 = (1,1-1,15) L1, where L1 is the width of the groove in its lower part, and L1 depends on the height S of the conical groove (Fig. 7), the limits L1 = (0.4-0.5) S. Between the neck of the hook and the end of the conical groove, a gap μ is formed (Fig. 7, 9, 10).

In the working position of the rack, the neck 4 of the hook does not touch the end of the conical groove, since there is a specified gap μ between the neck 4 and the end of the conical groove. The gap is selected to exclude the cut neck of the hook end of the conical groove during the operation of the rack.

In the first version of the rack, the vertical axis of symmetry 6 of the upper circular part 2 of the figured hole (Fig. 6) is parallel to the vertical axis of symmetry 7 of the rack (Fig. 4), and the longitudinal axis of symmetry 8 (Fig. 6) of the conical groove 3 is inclined at an angle α to the vertical axis 6 of the circular part of the hole in the range α = 2.0-3.0 °. In this case, the longitudinal axis of symmetry 8 of the conical groove 3 is inclined at an angle a to the angle of the rack and to the vertical axis of symmetry 7 of the rack (Fig. 4).

In the second embodiment of the rack, the conical groove 3 is located directly (without tilting) as shown in FIG. 8, and with this arrangement of the groove 3, its axis of symmetry 8 is located on the vertical axis 6 of the circular part 2 of the hole. In this case, the axes 6 and 8 are located on the same vertical line, which is parallel to the longitudinal axis 7 of the rack 1.

For two variants of the rack in the upper part, each conical groove 3 (Fig. 6) has a width L with a slope of its side edges from the axis 6 of the groove. Between the edges of the sides of the groove 3, an angle β is formed within β = 2.0-3.0 °. Each conical groove 3 has a height S.

Each conical groove 3 is made in the aforementioned manner in order to fix the engagement neck 4 between the inclined lateral edges of the groove as shown in FIG. 7, 9 and 10 - so that between the neck 4 and the end of the conical groove there is a gap μ, which excludes the cut of the neck 4 of the hook with the end of the groove during the operation of the rack.

Both shelving options have transverse beams 9 (FIG. 2) and longitudinal beams 10, which are connected to the uprights as shown in FIG. 4, 9. The end of each beam is made beveled to the middle of the beam, and each end of the beam has a bevel 11 (Fig. 2, 4).

Each hook 5 (Fig. 9) has an internal head 12 made integral with the neck 4 and rigidly connected to the beam, and an external head 13 made integral with the neck 4.

The round part of the rack hole has a diameter D (Fig. 6), while the diameter D1 (Fig. 9) of the outer hook head 13 is smaller than the diameter D of the round pillar hole 2 and larger than the diameter D2 of the inner hook head 12. The hook neck 4 has a diameter D3 (FIG. 7, 9). The ratio of the diameters D1 and D2 is selected from the condition of the bond between the beam and the strut with a hook working for bending and shear.

Each specified beam 9 or beam 10 (Fig. 2) is made of steel strip bent in the vertical and horizontal planes with the formation of a horizontal upper stiffening rib 14 in the form of a shelf (Fig. 4, 9), designed to support the flooring of the rack (flooring is not shown). Each beam has a lower stiffener 15 made of a steel strip, at the ends of which at least one hook 5 or two hooks is rigidly fixed, as shown in FIG. 9, in order to increase the carrying capacity of the rack. Each hook 5 is connected to the beam by pressing in the neck 4 of the hook in the hole of the lower stiffener 15, as well as by rigidly connecting the head 12 of the hook with the stiffener 15 of the beam. Each hook 5 is located near the bevel 11 of the beam (Fig. 4).

In two variants of the rack, there is one connection of each beam to the rack (Fig. 9), in which the wall 16 of each rack 1 of the rack is opposed between the surface 17 of the head 13 and the surface 18 of the lower rib 15 of the beam to ensure that the surfaces 19 and 20 of the wall 16 are pressed resistant to these surfaces 17 and 18.

Due to the pressing of the surfaces 17 and 19 and the surfaces 18 and 20 from the specified thrust force between the indicated surfaces, friction forces arise, while the load from the loaded beams of the rack is partially transferred from the beam to the wall 16 of the rack due to friction forces. In this case, the load on the neck 4 of the hook 5 is partially removed, acting on the neck cut from the lateral edges of the conical groove 3 acting on it. In this regard, the gap h between the surface 17 of the head 13 of the hook and the surface 18 of the stiffener 15 of the beam is less than the thickness t of the wall 16 of the rack 1 shelving.

To facilitate the combination of the surface 17 of the head 13 of the hook with the surface 19 of the wall 16 of the rack during the installation of the rack - on the inner side of the head 13 is made an entry chamfer 21.

It is essential that the edge of the aforementioned bevel 11 of each end of the beam is formed by a downward flange 22 (Fig. 5) and for the first variant of the rack, each flange 22 of the bevel 11 is located at right angles to the plane of the beam stiffener 14 and is directed downward from the stiffener 14.

For the rack of the second embodiment, each flange 22 of the bevel 11 is inclined to the plane of the beam stiffener 14 to the side from the middle of the beam and is directed upward from the beam stiffener 14 (not shown). Such an arrangement of the flanges of each beam for the rack of the second variant is selected in order to ensure tight flanging of adjacent beams of the rack of the second variant when the groove 3 of the rack is located, the axis of symmetry of which is located on the vertical axis of symmetry of the upper circular part of the hole (second embodiment of the figured hole) shown in FIG. 8. In the case of ensuring high precision manufacturing of parts of the rack of its second variant and guaranteed contact of the bevels of adjacent beams of the second variant of the rack, the flanging 22 of the bevel 11 of each beam is performed at right angles from the plane of the stiffener 14.

Each flange 22 may be directed both down from the stiffener 14 of the rack beam and up from the stiffener 14 of the rack beam (not shown). Moreover, each flange 22 can be inclined both to the middle of the stiffener 14 of the rack beam and from the middle of the stiffener 14 of the rack beam (not shown).

Bevel 11 of each beam with flanging 22 is made to increase the rigidity of the rack and the formation of the rectangularity of the rack in plan. For rectangular structures, each bevel 11 of each beam is made in a horizontal plane at an angle of 45 ° to the longitudinal axis of the beam.

The assembly of the rack is as follows. The racks 1 of the rack are fixed vertically in the mounting positions, they are inserted into the round parts 2 of the figured holes of the head 13 of the hooks, combining the neck 4 of each hook with the tapered groove 3 of the figured hole of the rack (Figs. 3, 4, 9). Moreover, each entry chamfer 21 made on the outer head 13 of the hook (Fig. 9) facilitates the insertion of the head 13 into the conical groove 3 of the figured hole of each rack rack.

Next, the beam is laid down with effort and with it each neck 4 of the hook 5 in the conical groove 3 of the rack 1 of the rack. In this case, each neck 4 is moved in an inclined groove 3 of the rack 1 and occupies a working position (Fig. 1, 3, 4, 9). Setting each beam of the rack down relative to the racks is performed by striking the tool along the stiffener 14 of the beam (Fig. 9), while displacing the rib 15 of the beam in the gap h between the surface 17 of the head 13 of the hook 5 and the surface 18 of the stiffener 15.

The movement of each neck 4 of the hook 5 in the conical groove 3 occurs until the neck 4 is firmly fixed in the groove, due to the indicated friction forces, the neck of the hook is securely fixed in the groove of the shaped hole of the rack both due to the friction forces from the thrust force and due to that it rests on the inclined edges of the conical groove 3 without touching the lower end edge of the conical groove (Fig. 10). During the operation of the rack, the gap μ between the neck of the hook and the end of the conical groove 3 is maintained.

Due to the inclined conical groove 3, inclined towards the axis of symmetry 7 of the rack (Fig. 4) during the assembly of the rack, each neck 4 of the hook 5 moves in a conical inclined groove 3 of the hole of the rack towards the axis of symmetry 7 of the rack until the neck is jammed into the groove. When moving the necks of 4 adjacent beams to the axis 7 of the rack, the beams together with the necks are shifted towards each other until the flanges of 22 adjacent beams are joined. As a result, the joined beams form a closed rectangular contour. When assembling a multi-tiered rack, such a rack has many closed rectangular contours that significantly affect the rigidity of the rack, its stability and strength.

In the process of assembling the rack flanging 22 are in contact and pressed against each other, which ensures the formation of a rigid rectangular in terms of the design of each tier of the rack without gaps in the joints. In the case of a multi-tiered rack, this rigidity is increased many times. The tier of the rack includes two beams 9, two beams 10 (Fig. 2) and a flooring (not shown) mounted on top of the beams.

If the conical grooves of the figured holes of the uprights are arranged as shown in FIG. 8, when the conical groove 3 is located directly (without inclination) and the symmetry axis 8 of the groove is located on the vertical axis 6 of the round part 2 of the hole, then in the process of assembling the rack, each neck 4 of the hook 5 is displaced vertically in the conical groove, until it stops in the inclined edges of the groove 3, while the neck is jammed between the inclined edges of the conical groove 3 in the same manner as described above. In the case of using rack racks with straight conical grooves 3, it is provided by calculation that the joining of flanges 22 of adjacent beams will be provided by other means - inclined flanges 22 inclined to the plane of the stiffener 14.

During the operation of the rack, the load from the rack floor is transferred to the stiffening rib 14 of each beam, then from the beam the load is transferred to the necks 4 of the hooks of each beam and, further, from each neck 4 of the hooks - to the rack 1 of the rack through the above-described connections of each hook 5 of the beam with 1 rack rack.

This design of the rack eliminates gaps in the joints of the beams with the racks, provides uniform load distribution on the racks from the beams due to the tight and more accurate fit of all the hooks in the openings of the racks, eliminates the overload of the joints due to uneven load, which ultimately made it possible to increase the carrying capacity of the rack to the design and thus increase the reliability of the rack. At the same time, installation of the rack is greatly simplified and the complexity of its installation is reduced. This rack eliminates the use of removable fasteners in its joints.

The design of the rack solves the problem of increasing its reliability while simplifying the design of the rack, the manufacturing process and installation of the rack without the use of additional fasteners.
