Description

A group of utility models relates to hoisting and transport machinery, in particular, to slings and their components, and can be used in various industries, for example, for packaging materials used to form packages of long loads (logs, metal, pipes and other materials) during their lifting, transportation and storage.

BACKGROUND OF THE INVENTION The closest packing line with a self-tightening loop is known from the prior art, which is a closed metal cable that forms at least one loop for tightening the load package, lasting at least one lifting loop, a larger tightening loop superimposed on the loop tightening and associated sliding sleeves in their neighboring sections adjacent to the package of cargo, while the sleeves are made with the possibility of crimping, preventing mutual movement of at least one loop and tightening and at least one lifting loop without a package of cargo and allowing them to move with the package of cargo, and a subsequent booster that completely prevents the mutual movement of at least one tightening loop and at least one lifting loop (see RU 79174 U1, published on December 20, 2008).

The disadvantage of the prototype is the one-time use of the packaging sling.

The closest wedge lock of a stacking sling containing the movable wedge and a clip, the conical surface of the inner cavity of which is configured to interact with the wedge and the sling, the wedge of which has a transverse bracket covering the sling with a screw pin for fixing the wedge relative to the sling, is known from the prior art. (see RU 2061631 Cl, publ. 10.06.1996).

The disadvantage of the prototype is the lack of fastening of the wedge in the sleeve in the idle state (absence of the packaging process), which does not prevent it from falling out of the sleeve.

The task of the utility model group is to make a stacking sling with wedge locks that is reliable and safe in operation, as well as capable of simultaneously packing the cargo and transporting it.

The technical result consists in providing the possibility of reusable use of a stacking sling and the absence of a wedge falling out of the sleeve.

The technical result is achieved by the fact that the self-tightening looping line is a closed metal cable that forms at least one loop of load tightening, lasting at least one lifting loop, a larger tightening loop superimposed on the tightening loop and connected with by at least two wedge locks in their neighboring sections adjacent to the load package, while wedge locks are configured to prevent mutual movement of at least one tightening loop and at least one lift loop.

Also, the technical result is achieved due to the fact that the wedge lock of the stacking sling contains a sleeve, dressed on a closed metal cable of the stacking sling and a wedge, and the surface of the inner cavity of the sleeve is made to interact with the wedge and sling, and the wedge is made with the possibility of changing its position in the sleeve and has safety protrusions from both its ends, preventing it from falling out of the sleeve.

Also, the technical result is achieved due to the fact that the ends of the metal cable are interconnected by at least one clamping fixed sleeve.

The technical result is also achieved by the claimed kit, including at least two of the claimed packaging slings.

The implementation of the claimed sling with wedge locks in this design allows you to repeatedly use it for packaging and transporting goods, as well as to eliminate the likelihood of a wedge falling out of the sleeve in an inoperative state (lack of a packaging process). The claimed effects are provided by a split wedge lock, the wedge of which together with the sleeve can repeatedly fix the loops of the stacking sling relative to each other.

A group of utility models is illustrated by the following drawings: FIG. 1 shows a view of a stacking sling with wedge locks, FIG. 2 is a longitudinal section of a wedge lock of a stacking sling, and FIG. 3 is a cross-sectional view of a wedge lock of a stacking sling.

The form of formation of a closed sling with a self-tightening loop involves the formation of a closed metal cable 1, located in the same plane, at least two loops 2, 3 due to the intersection of the parts of the metal cable 1.

The formed loop 3 is superimposed on the smaller loop 2, bending the metal cable 1. In this case, loop 2 is self-tightening and designed to tighten the load, and loop 3 is a lifting loop. At least two fixed clamping sleeves 6 and 7 are located in the upper part of the load tightening loop 2 of the closed sling.

To ensure the strength of the closed sling and the possibility of forming a package of cargo, adjacent sections of the load tightening loop 2 and lifting loop 3 adjacent to the load are interconnected by wedge locks 4 and 5. The wedge lock contains a sleeve 8, dressed on the strings of a packing sling and a wedge 9, this wedge has a safety protrusions 10 at both ends.

With the working position of the wedge in the sleeve of the string (metal cable) of the transport sling are fixed in a certain position - the sleeve is stationary. If the wedge is inoperative in the sleeve, the sleeve can freely move along the strings (metal cable) of the transport sling, the strings can change their position.
