BACKGROUND OF THE INVENTION The invention relates to cargo holding devices for transferring packaged cargo, mainly timber.

Known automatic mnogokischevye captures as single-rope, and dvuhkaiatnye, including the upper and lower frames or traverse with pivotally fixed on them tick-borne grips.

The purpose of the invention is to automate the overload of packages tied up by non-ring carrying flexible slings.

For this, in the proposed multi-tong grasp, the clamping surfaces of the tong-borne grippers have vertical ribs, the shape of which corresponds to the configuration of the chain on the upper bearing inserts of the sling, in order to avoid wedging the sponge of the castors, I have; a serrated edge, so that when they are closed, they enter the lock, and on the lower frame there are rotary squeezing eccentrics set in motion by means of connecting:.: and to the upper frame, and preventing the introduction of ticks when they are closed in the body of the nagaga. The accuracy of the gripper installation on the package is ensured by L-shaped rotary limiting stops mounted on the side of the bottom frame on the axes of the eccentric.

The design of the gripping surfaces of the gripper grips allows unloading cent2

t

The ral part of the upper strand of the carrier of a flexible structure and execute its design.

FIG. 1 shows the proposed mite trap, general view; in fig. 2 is a view 5 but the arrow A in FIG. one; in fig. 3 - nilchnll extremity of maple; in fig. 4 is a section, but BB in FIG. 3; in fig. 5 - schemes of building package of cargo. The load gripper consists of upper n lower

0 frames 1 and 2, but the corners of which are fixed to two pairs of tong-shaped grippers 3 having vertical ribs on the clamping surfaces of the casting bar. The profile of the ribs according to the configuration of the links of price or wihorop on

5 bearing inserts of the sling captured by the gnbkoi. Vertical edges pren tsgpu; o | the slippage of the structure in the gripper, which allows it to be limited to the introduction of the upper corners of the 1.1x Bcia0 wok into the congruence of the line, leaving the central part of the BCpXHcii straddle.

In order to avoid the wedging of the glues, with its clamped sling of the jaws, the teeth are performed, so that when the glue is closed,

3, they enter the lock (see Fig. 3). Shariir tick-borne grips are located on the lower frame, the traction link 4 of the lever mechanism is rigidly attached to the upper frame. The bottom frame of the four cables 5, zakrennyh

0 its corners, and the unifying ring 6 node

It is driven to the supporting rope of the crane lifting mechanism, and to the closing rope in the same way. Four eccentrics 7 are installed on the bottom frame of the load-carrying unit, which are used for squeezing it out at the moment the pack is captured. The upper ends of the eccentrics are connected to each other 8 with the upper frame. The lengths and the upper shoulders of the eccentrics must be in strict accordance with the change in the distance between the frames at the time of closing the tongs. The contour of the eccentric support surface should correspond to the trajectory described by the ends of the clamp jaws in the process of their closing. On one of the sides of the lower frame on the axes of the eccentrics there are two L-shaped restrictive stops 9.

Mnogokleshevoy capture works as follows.

The grip hanging on the supporting rope (see Fig. 5, position I) is brought to the package and installed on it with the help of н nors 9. As the closing cable is selected, the top frame 1 begins to lift, the clamping clamps 3 close by means of traction link 4 and turning off squeezing eccentrics 7 (see Fig. 5, position II). The eccentrics lift the lower frame above the package surface, preventing the tongs from penetrating into its body under the weight of the gripper and causing the ends of the tongs to slide on the surface. The clamp clamps 3 clamp the corner carrying valuable inserts of the upper part of the sling.

On the closing rope, the bag is carried to a predetermined location. After installation into the staple, the carrying cable is loosened, lowering the upper frame 1, thereby unlocking the tongs 3 and turning the eccentrics 7 to the initial horizontal position. In this case, the side stops 9, mounted on the same axes, are transferred to the working vertical position. Ready for the next cycle is captured on the supporting rope to the site of the next package.
