Description

The utility model relates to lifting and transport engineering, in particular, to devices for packing goods with a special outer coating or without it, loading them using hoisting machines into vehicles, further transportation and unloading at the end user.

From the prior art, a self-tightening loop bunching textile sling is known (RU 166719 U1, publ. 10.12.2016), in which 2 metal buckles are used as a fixing element. In slings of this design, when lifting the load in two loops located at the ends of the open loop of lifting the sling, the textile tape is pulled in the buckles, pulls the units of the load into the package and is fixed due to the frictional forces of the tape in the buckles, ensuring the preservation of the shape and size of the resulting package.

The disadvantage of slings of this design is the need to use metal buckles, which must have the necessary strength, the selection of sizes according to their location in the sling to ensure tightening of the bundling tape on the load for packages of different sizes in cross-section, significant material costs and significant laboriousness for their manufacture.

From the prior art, a self-tightening loop textile sling is known (RU 178087 U1, publ. 03/22/2018), which does not have metal elements, but does not provide guaranteed preservation of the shape and size of cargo packages during transportation, storage and storage.

A stacking textile sling is known from the prior art (RU 201477 U1, publ. 17.12.2020). This is a ring-type textile sling, which does not have metal elements, and quickly and reliably packs loads.

The disadvantage of such a sling is the impossibility of its use for packing and moving long loads with hoisting machines using spatial traverses having 4 points for securing the transported loads. In addition, when a wide textile tape is used for the manufacture of slings with a large carrying capacity, the sling tape can be collected in sweets on the load-gripping elements of hoisting machines and devices that are used when lifting and moving packaged loads, which can lead to an uneven distribution of the load along the width of the sling belt.

The task of the utility model is to create a sling for packaging cargo, which reliably packs the cargo when it is lifted, and can be used repeatedly.

The technical result of the claimed utility model consists in packing the load during its lifting with the possibility of using various load-gripping devices, moving and maintaining the shape of the package of the load after lowering without the use of additional fixing devices in the textile sling, and unpacking the load without cutting the sling.

The technical result is achieved in that the bunching sling contains an open textile tape, forming two branches of a lifting loop with loops at both ends, passing into a packing loop, consisting of loops of an open textile tape with the possibility of tightening the open textile tape and fixing it when lifting the load by the loops on the ends of the two branches of the lifting loop, each of the two branches of the lifting loop is located between the turns of the packaging loop, while an unpacking loop is made on one turn of the packaging loop.

The tightening (packing) of the cargo and its fixation in a packaged form occurs when the open textile tape is pulled under the influence of its own weight of the load when it is lifted by the loops located at the ends of the open textile tape, without the need to perform any additional operations to form and fix the package.

The specified design of the declared sling allows excluding from the design of the declared sling fixing devices in the form of buckles, additional straps from the tape or other devices that fix the bagging loop on the load after lifting and tightening. The existing loops at the ends of the open textile tape make it possible to use a textile tape without restrictions on its width in the manufacture of a bunching sling with the possibility of forming a folded loop, as is done in the manufacture of looped slings, and also to use such slings with spatial traverses. The unpacking loop made on one of the loops of the bundling loop of the bundling sling allows, if necessary, to quickly and conveniently unpack the cargo without damaging the open textile tape of the sling.

The open textile tape in the claimed sling is located in such a way that when the load is lifted by the loops at its ends with the formation of a lifting loop, the open textile tape is pulled, the load is tightened (bundled) with the textile tape of the bundling loop and it is fixed, i.e. clamping the open textile tape at the points of overlap of the loops of the packing loop and the lifting loop and holding the textile tape in this position due to the frictional forces that ensure reliable packing of the load. Moreover, on one side of the bunching sling, a turn that turns into a lifting loop can be located between the turns of the bunching loop, coming out from under them, and on the other side of the sling, a loop that turns into a lifting loop can pass between the bunching turns with the possibility of constricting an open textile tape and its fixation when lifting the load for both loops at its ends.

The cargo packed with the declared sling retains its shape unchanged after lowering, stacking packages on top of each other, transportation by different modes of transport. Even when slinging and lifting at the same time for all the turns of the open textile tape, the packaging loop of the load packed with the declared sling does not reverse the open textile tape, the shape of the package does not change.

It is possible to loosen the tightening of the bundling loop loops on the load, in order to remove the sling from it, when slinging and lifting the load, only for one loop of the bundling loop, which presses the tape of the lifting branch to the load. This can be done without difficulty if the units of the cargo to be stacked in one package have dimensions at which a free space is formed between them and the tape of the stacking loop turns passing from above, which allows you to insert a hook or other load-gripping element of the lifting device into it. This is most often possible when packing large cargo units in cross-section. In order to be able to unpack the sling on packages with units of the load to be packed of any size in the cross section, including small loads that are more tightly adjacent to each other, an unpacking loop is specially made on the sling, located on the turn of the packing loop, which is pressed against load a branch of the lifting loop. When lifting a package of cargo to a small height (200-300 mm is enough) for this loop, the tightening of the closed textile tape of the sling is weakened and it is pulled in the opposite direction. After unpacking and removing from the load, the declared sling can be used again.

The loops at the ends of the open textile tape are formed by stitching. If it is necessary to use a wide textile tape with the required breaking load for the manufacture of a sling, which can be assembled on the hooks of load-lifting devices used for lifting, the loops at the ends of the open textile tape can be made like a folded loop, as is usually done on looped textile slings, which allows to reduce the width of the belt in the loop at the point of its engagement on the lifting devices of lifting machines.

For convenience in working with the declared bunching sling, it has in the lower part of the sling a uniting sliding cover made of flexible or textile materials, through which an open textile tape passes. The uniting sliding cover can be composed of at least two parts, and can be moved to either side when it is necessary to inspect the condition of the part of the sling covered by the cover. In addition, the composite cover allows you to change its position on the sling, if necessary.

The unpacking loop can be made of flexible materials, can move freely along the bundling loop tape and allows you to loosen the tightening of the load for unpacking when lifting it.

The absence of metal elements or parts in the structure of the textile bagging sling eliminates the likelihood of damage to the surface of the cargo when it is packed and transported in these slings. This is especially true when transporting and storing goods with special outer coatings. Also, the reliability of the sling itself increases due to the absence of the likelihood of rubbing the textile tape of the sling in the metal elements of its structure during operation. In addition, the costs of manufacturing slings of such a design are significantly reduced, which ensures their greater availability for mass use for their intended purpose.

The claimed utility model is illustrated by Figures 1, 2 and 3. Figs. 1 shows a straight line view, a side view (left and right) and a top view of the claimed sling; in fig. 2 - the declared lanyard with a uniting sliding cover; in fig. 3 - a variant of manufacturing a sling with a two-piece uniting sliding cover.

Textile bunching sling for loads with or without surface coatings consists of an open textile tape with loops 1 at both ends, forming two branches of the lifting loop when they are put on the lifting body of the lifting mechanism (machine), which turns into the packing loop 2 formed by several turns of the open textile tape. The loops of the open textile tape in the sling are arranged in such a way that when it is pulled during the lifting of the load by the loops 1 at the ends of the open textile tape and after tightening (bundling) of the load with the bundling loop 2, the closed textile tape is fixed, i.e. its clamping in the places of overlap of the tape of the turns of the packaging loop and the lifting loop and their holding in this position due to the friction force. The loops at the ends of the open textile tape are formed by stitching 3.

To unpack the load, the sling has an unpacking loop 4 located on the turn A of the packing loop 2, as shown in FIG. 1, 2 and 3. The unpacking loop 4 is made of flexible, for example, synthetic or textile materials and can move freely along the loop A from one edge of the cover 5 to the other.

When lifting the load packed with a sling by the unpacking loop 4, located on the turn A of the packing loop 2, with which the tape of the lifting branch with loop 1 is pressed to the load, the tightening of the packing loop is loosened and the open textile tape is pulled back, which allows unpacking the load without damaging the sling tape and use the sling again.

The claimed lanyard, as shown in FIG. 2, is made with a uniting sliding cover 5, made of flexible or textile materials, located in the lower part of the sling through which the open textile band passes.

A variant of a sling with a composite uniting sliding cover 5, consisting of at least two parts, is shown in FIG. 3.

Work with a sling is performed as follows.

When packing a load, a textile packing sling is brought from the end of the load, laid on the gaskets or in the cradle. Both loops 1 at the ends of the open textile tape are hung on the lifting device (for example, a hook) of the lifting machine and the load is lifted, while the open textile tape is pulled in the bunching sling and the package is tightened under the action of its own weight by the bunching loop 2. The load is fixed in this position due to clamping the tape at the points of overlap of the loops of the packaging loop and the lifting loop of the open textile tape and holding the tape in this position due to friction forces. The created tightening force allows the package of cargo to retain its shape after lowering it, during further movements, reloading and transportation.

Unpacking the package of cargo is carried out when lifting the package of cargo by the unpacking loop 4, located on the turn A of the packaging loop 2. After removing the bundling sling from the package and returning the turns in the packaging loop to the initial state before packaging, which is easily done manually, the sling can be used again according to appointment.

For palletizing long loads, it is recommended to use 2 bundling straps.
