Description

CONTAINER FOR TRANSPORTATION OF STEEL ROLLS

The invention relates to shipping containers, in particular, to large-capacity containers for transportation and short-term storage of steel coils in a horizontal position, steel coils in a vertical position on pallets, sheet steel in packed bundles on pallets, cylindrical cargo and other piece cargo general purpose.

From the source RU 2610569 C2, B65D 85/66, 02/13/2017, a container for transporting products is known, in particular, in the form of bays, containing a floor, two side walls, a front wall, two doors with a lock and a removable hard top with a fastening mechanism, moreover the floor is equipped with swivel supports with mutual fixation, grouped in pairs, located along its longitudinal axis of symmetry opposite each other, and in the closed position they form a horizontal plane with the floor, and in the raised position they form a chute, while the swivel support, which is part of one pair, consists of a first flap connected to the support of the first flap, or a second flap connected to the support of the second flap.

The disadvantages of the known solution are the insufficient strength of the base (floor) structure with significant loads acting on the base of the container when transporting steel coils and cylindrical goods in a horizontal position, the lack of means of fastening (fixing) steel coils when transporting them both in horizontal and vertical positions , the possibility of longitudinal movement of steel coils inside the container when transportation, the possibility of unauthorized removal of the roof from the container and the need to use slingers-riggers to remove the roof.

The technical problem to be solved by this invention is the possibility of using one type of container, the design of which provides for the transportation of steel coils, both in horizontal and vertical positions, transportation of steel sheets in packed bundles on pallets, cylindrical cargo and other piece cargo, using the entire useful internal length, as well as the creation of an easy-to-operate, reliable during maintenance, resistant to plastic deformation of the container structure, ensuring complete safety of fastening and stable position of the goods located in the container during their transportation.

The technical result achieved by the claimed invention consists in the effective use of a container for transporting coiled steel in both horizontal and vertical positions, reliable contact fastening (fixation) of coiled steel during transportation in both horizontal and vertical positions, ensuring the necessary margin of safety for parts and uniform distribution of loads arising from the impact of the transported cargo.

The specified technical result is achieved in a container for transporting steel coils in a horizontal position, steel coils in a vertical position on pallets, sheet steel in packed bundles on pallets and general cargo, containing a base, side walls, a front wall, end doors and a removable roof equipped with internal locking system, while the base contains at least four pairs of reinforced frameless hinged caliper cradles, symmetrical in length, consisting of hinged support and strut channels capable of receiving horizontal and inclined position, wherein the container contains a pair of two-tier non-removable articulated-swivel, longitudinal-transverse I-beams, the opposite ends of which are pivotally connected to the cassettes, which are installed with the possibility of longitudinal movement along the pair of two-tier guide channels located on the side walls of the container, on the upper and lower shelves of which coaxial holes are made, while fixing the articulated longitudinal-transverse beams in the longitudinal and transverse positions at the desired points of the guide channels is carried out using cylindrical and conical pins.

Execution of the base from a reinforced frame, with support cradles installed on it, consisting of support and strut channels capable of taking horizontal and inclined (in the form of the letter "M") positions, reinforcement of the caliper cradles with metal sheets connected into a single whole with support and strut channels , provides high stability of cargo during transportation, reduces the impact of loads on the elements of the container structure and gives the necessary margin of safety for uniform distribution of loads arising from the impact of the transported cargo, thus increasing the reliability of all container structures.

The use of paired (upper and lower) two-tier fixed longitudinal-transverse reinforced I-beams with cassettes, which are installed with the possibility of longitudinal and transverse movement along paired two-tier guide channels located on the side walls of the container, ensures reliable fastening and stable position of cargoes of various sizes (steel rolls , cylindrical cargo, general cargo, etc.) located in a container, when they are transported as in horizontal as well as vertical position.

Swivel joints allow convenient and free movement of beams with cassettes in the longitudinal-transverse direction along the guide channels inside the container, allow reliable contact fastening (fixation) of rolled steel in a horizontal position, rolled steel in a vertical position on pallets, sheet steel in packed bundles on pallets and general cargo at the desired point, and provide the ability to move the beams between the transport position (beams are located longitudinally along the guide channels), and the working position (beams are located transversely to the side guide channels).

If residual stresses occur in the beams - elastic deformation, bending moment from the action of cumulative dynamic forces (inertia, etc.), conical fingers are used to remove and release them, which prevent further clamping ("biting") of the cylindrical fixing fingers of the beams and the cassette receiver, which improves the reliability of the container design during operation. This excludes spontaneous loss from the holes of the side guide channels and cassettes that fix the conical and cylindrical pins.

The application of an anti-slip composite coating on the upper steel sheets of the caliper cradles makes it possible to increase the coefficient of friction, preventing arbitrary movement of cargo inside the container, and additionally protects the metal from corrosion, contributing to an increase in the reliability of the container structure during operation.

Strengthening the side walls of the container with side two-tier guide channels for moving the longitudinal-transverse beams, gives rigidity and strength to the structure, reduces the risk of damage and increases the reliability of the structure as a whole during operation. At the same time, the guide channels have a torus-spherical section formed by two channels with reinforced shelves interconnected by electric arc welding.

The design of the container provides the necessary margin of safety for parts, reliable contact fastening (fixation) during the transportation of rolled steel in both horizontal and vertical positions, including steel sheet metal, packed in packs on pallets and ensures uniform distribution of loads arising from the impact of the transported cargo.

Large-tonnage container (figure 1, 1a) for transporting steel coils in a horizontal position, steel coils in a vertical position, located on pallets, sheet steel in packed bundles on pallets, cylindrical cargo and other piece cargo of general purpose, contains a base 1 (floor), side walls (2), front end wall (3), rear end wall with doors (4), top rotary-reversible beam (5), removable hard metal roof (6) and corrugated panels (7).

The structure of the base (1) (Fig. 2) is formed from reinforcement elements - a bearing main beam (9), longitudinal channels (9.1), transverse T-/I-channels (9.2), toro-spherical metal boxes for forklift forks (9.3), interconnected by means of electric arc semi-automatic welding with continuous seams, forming a single reinforced frame structure resistant to plastic deformation.

Along the right and left side walls (2), at the base of the container (1), by means of semi-automatic electric arc welding, metal boxes-lockers (1.4) with upper strong hinged lids are installed, in which there are cylindrical holes for easy opening (1.5) (Fig. 2-3). Lockers (1.4) are designed to store multi-turn means of securing the load, for example, ratchet tie-down straps, chains, cables, etc.

At least four pairs of reinforced frameless hinged caliper lodgements (10) symmetrical in length are attached to the bearing main beam (9) and transverse channels (9.2) (fig.3). Support cradles (10) consist of support (10.1) and strut channels (10.2), connected to each other and to the main beam (9) using powerful steel pins (10.3), forming articulated joints (Fig.4-5). From above and from the side, the support cradles (10) are reinforced with top and side metal sheets (10.4), welded by electric arc welding to the channels of the calipers. The upper steel sheets are coated with an anti-slip composite coating (10.5).

The structure of the base (1) can accept both fully horizontal position for the transport of steel coils in a vertical position on wooden pallets, steel sheets in packed bundles on pallets and general cargo, including drums, cargo on pallets, and an inclined position (vertical profile) in the form of the letter "M", which allows the transport of steel rolls and other cylindrical loads in a horizontal position (figure 2-5).

The inclined position in the form of the letter "M" is formed by lifting the hinged support cradles (10) with the help of special handles. With the horizontal and inclined positions of the support cradles, the handles are in stamped grooves located in the upper metal sheets (10.4) and do not protrude beyond the plane of the metal sheets. In order that, when installed in an inclined position, the struts (10.2) of the support cradles (10) take a strictly defined angle equal to 75 °, special support recesses are provided in the base of the container in the form of rectangular recesses (1.3), located on the left and right along the entire internal longitudinal length container (Fig.4-5).

Fastening / fixing of steel coils in a longitudinal horizontal position, steel coils in a vertical position on pallets, sheet steel in packed bundles on pallets and general-purpose cargo in a container is carried out using paired, arranged in two tiers, upper and lower fixed articulated-swivel longitudinal transverse beams (11), the opposite ends of which are pivotally connected to the cassettes (12) (Fig.6-9).

Articulated longitudinal-transverse beams are made of reinforced I-beam channel (11) with perforation (11.1). The opposite cantilever parts (opposite ends) of the I-beams (11) are reinforced at the top and bottom with additional metal plates (pads) (11.2), which are connected to the channel by means of electric arc welding and between which a receiving cavity (11.3) is formed (Fig.6-7) . In steel plates, coaxial cylindrical and conical holes (11.4). On one side of the beam, the receiving cavity is connected by means of a cylindrical steel pin (14) to the receiving part of the cassette (12.1) (which also has cylindrical (12.4) and conical holes (12.5) (Fig. 10)), which is further expanded, forming with on one side of the beam, a non-removable swivel joint with a cassette (12) (Fig. 8). In the transport position, i.e. when there is no load in the container, the beam (11) is translated into a longitudinal position along the guide channels (13), rotating around a fixed swivel with a cassette (12) located in the guide channel (13) (figure 1). In this case, the opposite (second) free receiving cavity (11.3) of the beam (11) is connected by a cylindrical pin to the receiving part of another cassette (12) located on the same guide (13). Thus, in the transport position, all beams (11) can be located and securely fixed along the longitudinal guide channels (13) (figure 1). When the beam is moved to the transverse position (i.e., the working position during cargo transportation), the remaining free receiving cavity (11.3) of the cantilever part enters the receiving part (12.1) of the cassette (12) located in the side (opposite) guide channel (13) (fig.1a, 7-8).

The beam and the cassette are fixed by means of cylindrical (14) and conical (15) pins, which are connected to the beam by means of chain drivers (14.1) and (15.1). In the transport position, cylindrical (14) and conical pins (15) are stored in special canisters (16) located on beams (11). Articulated and swivel joints created with the help of cylindrical and conical pins make it possible to conveniently and freely move beams with cassettes in longitudinal and transverse positions inside the container, provide reliable contact fastening (fixation) of rolled steel in a horizontal position, vertical position on pallets, sheet steel in packed bundles on pallets and general cargo at the desired point. The cassette (12) is made of three metal plates: upper (12.2), middle (receiving part) (12.1) and lower (12.3), interconnected by welding (Fig. 10), which gives the part additional strength. In the part of the cassette, which is inserted into the side guide channel (13), cylindrical holes (12.4) are made, the pitch of which coincides with the pitch of the holes in the channel guide (13). Cylindrical (12.5) and conical holes (12.6) are made in the receiving part of the cassette (12.1) (Fig. 10). Fixation of the cassettes to the side upper and lower guide channels at the desired point is carried out using cylindrical pins (13.2) entering coaxial (combined) holes in the guide channels (13) and cassettes (12), while the cylindrical pins (13.2) are connected by chain leashes . Cassettes (12) are not removable; for their repair or replacement, special repair inserts (13.3) are provided on the channels (Fig. 11).

The side guide channels (13) have a torus-spherical section formed by two channels (13.4) and (13.5) with reinforced shelves connected to each other by electric arc welding (Fig. 12). In the upper and lower planes of the channels (13) coaxial cylindrical holes (13.7) are made, the pitch of which coincides with the pitch of the cylindrical holes (12.5) of the cassettes (12) (Fig. 9). Using automatic electric arc welding, the side paired upper and lower toruspherical channels (13) are connected to the metal corrugated sheets of the container walls (7) cladding, forming additional reinforcement for the side walls of the transport equipment.

The side walls (2) are a rectangular frame, consisting of steel longitudinal and vertical channels, connected by semi-automatic electric arc welding with strong corner fittings, made in accordance with the standard: GOST R 51891/ISO 1161-2016-2. From the outside, sections of corrugated steel sheets (7) are welded to the frame using electric arc welding with a continuous seam, thus forming a single rigid structure. Inside the container, to the upper and lower load-bearing longitudinal channels of the frame of the side walls, shackles are welded, designed for additional fixation (in transverse and longitudinal positions) inside the container of rolled steel using multi-turn fasteners, such as: belts, cables, chains, etc.

In order to exclude the ingress of moisture and atmospheric precipitation, all welded seams of the side walls are treated with silicone sealant, primed and painted. In order to prevent the formation of condensate inside the container with the doors and roof closed, in the upper right part of the side walls, there are special ventilation openings that provide air inflow and exhaust into and out of the container.

To exclude direct ingress of atmospheric precipitation in the form of rain, snow, etc. through the ventilation openings, gratings (deflectors) are installed on them, attached to the side walls with rivets. Existence of lattices provides natural ventilation of the container. The joints of the grating and container walls are additionally sealed with moisture-resistant silicone sealant.

The front wall (3) is a rectangular frame, consisting of steel longitudinal and vertical channels, to which sections of corrugated steel sheets (7) of the reinforcement element are welded from the outside. The front wall (3) is connected with 4 corner fittings of the longitudinal side walls using semi-automatic arc welding, forming a single rigid structure, which together leads to the reliability of the entire container structure. For the convenience of climbing onto the roof (6), steps are located on the outer surface of the front wall (3).

The rear wall (4) of the container has a doorway, in which one pair of hinged end doors with locks is mounted, each of which is hung on four strong hinges. End doors are a frame structure formed by load-bearing profile channels, sheathed on the outside with corrugated steel sheets. Principle of operation: the left door closes first, it is covered by the right one when closing, i.e. it is impossible to open or close the left door without opening the right one.

For opening/closing end doors, locking devices are installed on the outer surface in the form of vertical levers with locking seats and handles with locks, with locking swivel caps, having holes for sealing. Along the perimeter, the doorway is sealed with a profiled rubber gasket. On the end doors, a product characteristic is applied, in which all the main parameters are encoded, such as a KBK / KTK plate containing information on the permissible load capacity, weight, volume, information about the owner, as well as other symbols. For the convenience of climbing onto the roof (6), steps are located on the outer surface of the left door, and a handle-bracket is located on the reversible beam (5).

The roof (6) is made removable (Fig.13-15), which allows loading the container through the open top. The roof is a rigid metal frame, which consists of horizontal (longitudinal) (6.1) and transverse (6.2) channels, additionally connected in the central part with longitudinal (6.3) and transverse (6.4) profile channels, reinforcing the roof (6). To create a solid unified roof structure, metal corrugated sheets (7) are welded to the frame from above to the frame using semi-automatic electric arc welding, left and right, in the center a sheet of flat metal (6.5). Along the perimeter of the lower surface of the supporting frame of the roof 6, a rubber profile gasket (6.6) is installed, which ensures complete tightness of the roof (6) and the safety of goods from external influences (ingress of precipitation, dirt, etc.). Three lugs (6.7) for locking mechanisms (6.8) are welded to the outer plane of the longitudinal bearing channels of the frame, on the left and on the right. From above to the roof frame flared corrugated steel sheets (7) are welded with a continuous seam. On the left and right longitudinal sides of the supporting frame channels there are two rotating cranks (6.9) and (6.10), which are designed to bring 2 pairs of special reinforced brackets (6.11) into a vertical position in the form of an equilateral trapezoid, located in the central part of the roof, where the roof is reinforced, to remove the roof with a crane with a special lifting bracket for loading steel coils and cylindrical loads. The fastening of the brackets to the top sheets of the roof using semi-automatic arc welding is carried out by 4 pairs of thick-walled bushings (6.12), which form articulated joints, the cantilever parts of the brackets (6.13), have special oarlocks with internal square grooves (6.14) for inserting an external square ( 6.17) of a switch key (6.15) hinged to the bar (6.16). The outer square (6.17) of the switch key (6.15) is inserted into the inner part of the oarlock (6.14) with the help of a rod and the rod (lever) is turned clockwise along the side wall of the container, which brings the brackets to the vertical position (6.11) from the ground plane. Folding the staples is done in reverse order. The presence of folding brackets, as one of the constructive inventions, makes it possible to remove / install the roof using lifting mechanisms equipped with special brackets for moving, loading / unloading steel coils and cylindrical loads without lifting the container slingers - riggers onto the roof (6). In order to prevent unauthorized removal of the roof (6) from the container, the roof (6) has an internal lock (17) in the form of internal locks, consisting of special chain leashes (17.1) with adapter carabiners (17.2), equipped with threaded locks with fastening mechanisms. The last link of the chain leader (without a carabiner) is attached to the longitudinal channel (2.2) of the side walls of the container with the help of semi-automatic electric arc welding, the reverse part of the chain a leash with a carabiner is fixed to the supporting legs of the roof. The presence of an internal blocking system makes it possible to exclude attempts of unauthorized removal of the roof (6) from the container by third parties. For the convenience of the correct orientation of the roof (6) by the crane operator, when it is installed in its original position, on the outer sides of the transverse channel (6.2) of the roof frame (6) there are color markings in the form of two black stripes (6.18), and on the upper horizontal (longitudinal ) channels (6.1) in red, the places (6.19) for laying brackets (6.7) are marked, to which the upper L-shaped roof locks (6.8) are fixed. In addition, crossed red stripes (6.20) are applied in the center of the roof (center of gravity), which are markings for lowering the load-lifting magnetic washer to this point. For laying and stacking roofs removed from containers on a solid surface of the earth, 8 support legs (6.21) in the form of a rectangular trapezoid are welded to the internal load-bearing channels of the frame from below. The central part of the roof (6) is made of flat metal (6.5), which allows it to be removed using an electromagnetic washer. Removing the roof (6) can be done using lifting slings; for this purpose, eight hinges (6.22) are welded to the outer surface of the longitudinal load-bearing channels. The fastening of the hinges to the outer surface of the longitudinal load-bearing channels using semi-automatic electric arc welding is carried out using thick-walled bushings (6.23), which form articulated joints.

The steel coil transport container is used as follows.

For loading into a container through an open doorway of tare cargoes in Big-bags, Euro-pallets and other piece cargoes, including in bulk (not loose): the locking and sealing devices (LPU) are removed from the handle of the right door of the empty container, after which fold up the overhead retainers ("ears") of the handles of the levers of the end doors, open the end doors and fix them. Then, a ramp of the appropriate type is installed on the door sill of the container, using an electric car, forklifts or manually, the cargo is placed and fixed in the container using articulated fixed beams according to the scheme approved by the carrier.

Before removal, the roof must be cleaned of dirt, ice, snow, check whether a blockage has been installed, if it has, it must be removed, use the rods to open the six side locks of the roof holders and once again make sure that there are no obstacles to hold the roof. The roof can be removed in several ways: using a lifting magnetic washer, lifting straps of the required length, a special lifting bracket for loading/unloading steel coils. To remove the roof with a lifting bracket used for loading / unloading steel coils, using a special key, the brackets are raised from the ground in the form of an equilateral trapezoid located on the upper plane, while lifting the slinger to the roof is not required. The crane operator removes the roof from the container and lowers it onto the legs, which are located on the outer side of the bearing channels, on the flat surface of the container platform or container terminal, which has a hard coating -

To load steel coils in a horizontal position through the upper opening into the container, the seals are first removed from the handles of the locking devices of the empty container, the overhead retainers (“lugs”) of the handles of the end door levers are folded up, the end doors are opened and fixed. If necessary, the rotary-reversible upper traverse (beam) located above the doorway is moved to the side. Then, starting from the first pair from the front blank wall, 4 caliper lodgements are installed in an inclined position in the form of the letter "M". Depending on the width of the strip and other parameters of the steel coil, according to the loading scheme, the slinger moves along the upper (right/left) side guide channels of the upper beam and fixes it at the desired point with cylindrical and conical pins to the receiving part of the cassette and side (left/right) channels. The same operation is performed with the lower beam. The upper and lower beams in the transverse position must be located strictly vertically (coaxially) in the same plane. The crane operator inserts the tooth of a special bracket into the inner hole of the steel coil located in the finished product warehouse, lifts the coil, making sure that the fastening is secure, moves the coil to the container and smoothly brings it inward along the central longitudinal axis of the container (spine beam). Lowers the roll onto the raised support cradles, close to the beams previously set in the transverse position. The installation of the following rolls is carried out close to the previous one as long as the internal useful length of the container allows, taking into account the installation with fixation by fingers close to the outermost roll of the upper and lower beams located at the doors, while making sure that there are no obstacles to closing the doors . The steel rolls mounted on support cradles are additionally fixed in a transverse position (according to the loading schemes) using multi-turn fasteners, for example, ratchet straps. The belts are thrown over the rolls, and their cantilever parts (hooks) are inserted into the shackles located along the side walls of the container, after which the belts are tensioned. The belts prevent rolls and cylindrical loads from shifting and rolling inside the container in the transverse direction.

To load steel coils in a vertical position through the upper opening into the container, the seals are first removed from the handles of the locking devices of the empty container, the overhead retainers (lugs) of the handles of the end door levers are folded up, the end doors are opened and fixed. Depending on how (using electric car, lifting overhead, gantry, automobile crane, etc.), it is supposed to be loaded, the rotary-reversible upper traverse (beam) located above the doorway is set aside. According to the loading schemes approved by the carrier, steel rolls on wooden pallets are installed on the horizontal support bases of the base. For fastening of steel coils located vertically on pallets, articulated longitudinal-transverse beams with cassettes are used. The slinger first moves and fixes the lower beam close to the pallet with the help of cylindrical and conical fingers, then the upper beam with cassettes close to the steel roll and fixes it with the help of cylindrical and conical fingers. Since the used wooden pallets have constant linear dimensions (GOST 33757-2016 Flat wooden pallets), and steel rolls have different outer diameters, the upper and lower beams in the transverse position can be located in the transverse position not strictly vertically (coaxially) in the same plane. Subsequent steel coils are installed and fixed by longitudinal-transverse beams with cassettes in a similar sequence.

To load sheet steel in packed bundles on wooden pallets through the upper opening into the container, the seals are first removed from the handles of the locking devices of the empty container, the overhead retainers (“lugs”) of the handles of the end door levers are folded up, and the end doors are opened and fixed. Depending on the way (using an electric car, a lifting bridge, gantry, automobile cranes, etc.) it is supposed to load, a rotary-reversible upper traverse (beam) located above the doorway is set aside. According to the loading schemes approved by the carrier, sheet steel in packed bundles on wooden pallets is installed on horizontally located caliper cradles of the base. For fastening sheet steel in packed bundles on wooden pallets, non-removable articulated, longitudinal-transverse beams with cassettes are used. The slinger first moves and fixes the lower beam close to the pack with the help of cylindrical and conical fingers. If the loading scheme provides for a two-tiered (one on top of the other) installation of sheet steel in bundles on pallets, then the upper bundles are fastened using upper transverse beams with cassettes. Any loading of the container is carried out in accordance with the approved technical specifications (TS) or local technical specifications (LTU) and the scheme (s) of loading and securing cargo, while the total gross weight of the container should not exceed the value of M gross = 41,000 kg.

This design of the container provides the necessary margin of safety for parts and high (safe) stability of goods during transportation, reliable contact fastening (fixation) during transportation and storage of coiled steel both in horizontal and vertical positions, sheet steel in packed bundles on pallets and general-purpose cargo and uniform distribution of loads arising from the impact of the transported cargo.
