RU2230012C1 - Container transportation tray - Google Patents

Abstract

FIELD: metallurgy; transportation of slag pots with ingot moulds. SUBSTANCE: proposed tray contains base with fitted on stop and side walls made in form of semiposts. At least one post is arranged between side walls. Semiposts and post are provided with inclined surfaces changing into vertical slops required for preliminary and final orientation of containers at their placing on tray. Distance between vertical slopes provides small mounting clearance of 5-10 mm sufficient for accurate placing of ingot moulds with slag pots on tray, and minimum clearance between upper parts of two standing slag pots installed stationary on corresponding ingot moulds to preclude passage of slag in between at simultaneous charging with slag. Stop is made in form of beam being arranged side of ingot moulds with slag pots placing onto tray by means of loader. Thrust beam is rigidly secured to side walls and post from opposite side of stop. Stop and thrust beam serve as limiters in cross direction when placing, charging and transporting slag pots with ingot moulds and provide additional rigidity of tray, together with semiposts and post. EFFECT: reduced metal losses in slag, increased capacity at unloading of slag from melting furnace. 3 dwg

Description

The invention relates to technological equipment and can be used in metallurgy for the transport of slag molds with molds.

A known pallet for transporting goods containing a base with hinges, end and side walls, stops (see AS No. 564219, class B 65 D 19/12, 07/05/1977).

A known pallet for transporting containers containing a base with a fixed support thereon, side walls (see application EPO (EP) No. 0443500, Cl ⁵ B 65 D 19/02, 19/44, publ. 28.08.91) - prototype.

A disadvantage of the known devices is the low productivity of the discharge of slag from the smelter, since one tank is loaded and metal losses due to the burning of metal in the slag as a result of the length of time when it is delivered from the smelter threshold to the press for slag extraction.

The objective of the invention is to reduce metal losses in the slag, increase productivity and reduce the time of unloading of slag from the smelter.

The task is achieved due to the possibility of quick unloading of slag from the smelting furnace through the use of two containers at once and transportation with one pallet, in which they are fixed from moving, as well as unloading them using a loader. This, in turn, is achieved by the fact that at least one pedestal is located inside the pallet, which allows two containers to be installed in the gap between it and the side walls of the pallet, made in the form of half-tables, while preliminary and final installation is ensured. the orientation of the containers due to respectively inclined surfaces, turning into vertical bevels, made on half-tables and pedestals and located opposite each other.

The presence of a stop on the base of the pallet and a stop beam located on the opposite side of the stop and rigidly fixed to the side walls of the pallet and the pedestal, respectively, prevents containers from shifting when loading with slag and limits the movement of containers when installing them on the pallet with a loader, as well as fixing containers during transportation .

The task is achieved by the general features of the proposed solution with the prototype:

- a base with an emphasis fixed on it,

- side walls.

New features of the claimed pallet in comparison with the prototype are:

- the side walls are made in the form of half-tables having in the upper part inclined surfaces directed into the inside of the pallet, turning into vertical bevels,

- at least one pedestal is installed between the side walls, having in its upper part inclined surfaces turning into vertical bevels symmetrically located relative to the vertical axis of the pedestal and intended, respectively, for preliminary and final orientation of the containers when installing them on a pallet,

- the emphasis is made in the form of a bar, located on the side of the loading containers and is designed to shift containers from the pallet during transportation,

- the pallet is equipped with a stop beam located on the opposite side of the stop and rigidly fixed to the side walls, pedestals, and is necessary to limit the movement of containers when installing them on the pallet.

The invention is illustrated in the drawing, where figure 1 shows a General view of the pallet, front view; figure 2 is a view in plan of figure 1; figure 3 is a side view of figure 1.

The pallet for transporting containers contains a base 1, side walls 2 and at least one cabinet 3 located between them.

The side walls 2 are made in the form of half-pedestals having inclined surfaces 4 in the upper part directed into the inside of the pallet and turning into vertical bevels 5.

On the side walls 2 there are trunnions 6 designed for slinging the pallet with a 4-chain chain sling 7 of an overhead crane (not shown).

Half pedestals and pedestals are made of steel sheet material.

The cabinet 3 has inclined surfaces 8 and vertical bevels 9, symmetrically located relative to the vertical axis of the cabinet.

Between the pedestal 3 and the side walls 2, containers are installed, in this case consisting of slag containers 10 and molds 11 installed under them.

The distance between the vertical bevels 5 and 9, located opposite each other, should be such that, firstly, there is a small installation gap (5-10 mm), which provides a fairly accurate installation of the molds 11 together with the slag mills 10 on the pallet, and, in secondly, a minimum clearance was achieved between the upper parts of two standing slag containers installed fixed on the corresponding molds 11, which excluded the passage of slag between them while loading the slag from the furnace threshold.

Between the side walls 2 can be installed several pedestals, similar to the pedestal 3, designed to install additional containers.

The pallet has a stop 12, made in the form of a bar, located on the side of the tank on the pallet on the base 1, and a stop beam 13 located on the opposite side of the stop 12 and rigidly fixed to the side walls 2, stand 3.

The thrust beam 13 ensures the rigidity of the base 1 along the length and serves as a limitation in the transverse direction when installing the molds 11 on a pallet and slag molds 10 on the molds 11 with a loader.

The stop 12 has a height sufficient for the forklift to pass above it during installation and removal of the mold 11 with the slag ladder 10 from the pallet and serves both to limit the shift of the molds 11 in the transverse direction during loading and transportation, and to provide additional rigidity to the pallet.

Additional rigidity of the pallet is also provided by the execution of the side walls 2 in the form of half-pedestals and the presence of one or more pedestals 3, which is important when transporting the pallet.

The pallet is used as follows.

Pre-install the slag vessel 10 on the mold 11, having openings, respectively, 14, 15 for the forks of the loader.

With the help of a loader, the slag bowl 10 with the mold 11 raises to a height that allows them to freely move them into a free cell on a pallet. Advancing the leading edge of the mold 11 approximately in the middle of the pallet, the mold with the slag masonry 10 is lowered onto the pallet by the loader, while the mold slides on the lower part along any inclined surface of the cabinet 3 or side wall 2 along the guide until it falls between the vertical bevels 5, 9 . Without stopping the lowering, the loader moves the mold 11 all the way into the stop beam 13 and lowers it onto the base 1 of the pallet.

The same is done with another mold and slag.

Then the loaded pan is slinged with a crane and delivered to the threshold of the melting furnace (not shown), from which it is necessary to remove slag.

The pallet is set close to the threshold of the furnace and, using a multi-filling machine (not shown), fill both slag containers to the top with slag. Then, the pallet is transported by a crane to the slag extraction section and, using a loader, each slag mold with the mold is removed in turn and placed in a press, pressing slag.

The claimed invention allows to reduce the loss of metal in the slag by 25 - 30% when removed from the smelter and transported from the smelter to the press for the extraction of slag.
