(U1 1 The invention relates to lifting transport technology, in particular to grips for transportation in the vertical position of a hollow product: sj. A gripper for transporting in a vertical position of hollow products is known, comprising a frame, at least two pairs of gripping arms, one of each pair which is hinged on the frame, and the locking mechanism of the gripping levers, which includes a slider with an element for hanging the hook of the load-lifting mechanism C,. The disadvantage of this grip is low reliability, as if, for example, For example, if a pipe is seized, the wall thickness is permeable around the perimeter, then the gripping levers slim the wall of the pipe only at its maximum thickness, as a result of which the pipe can be deformed and dropped out of the grip during transportation. that the gripper for transportation in the vertical position of the hollow articles, containing the frame, at least two pairs of gripping arms, one of each pair of which is hinged on the frame, and the locking mechanism of the gripping arms, Including a slider, with an element for hanging on a hook of a lifting mechanism, is provided with a hinged attachment to the slider with a balance bar connected to the second lever with each pair of kinematics, with the first lever of each pair hingedly attached to the second lever, which is clamp-shaped and jointed with it Attaching to the frame is located in its middle part. FIG. 1 shows the capture view, the initial position; on .fig. 2 and 3 are the same, the workers are supposedly A in FIG. 1; in FIG. A gripping device for transporting hollow articles in the vertical position, the advantage of pipes, comprises a frame 15 for fixing the gripping levers, including a guide 2 fixed to the frame I, creep 3 with an eyelet 4 for hanging 1 and a hook on the load-carrying mechanism and a lock 5, holding the slider 3 in a predetermined position from the IO.ite..t1no frames I, ob26 The gripper also contains gripping levers 6 and 7, with the levers 6 made of brackets, set on the axis x 8 frames located in the middle part of each lever 6 and pivotally zany with ryu gami 7 interacting by means of articulated rods 9 with rocker iO, B1arnirno attached to the bottom of the slide 3. The frame is provided with a guide member 1, obespechivayush.im necessary orientation relative gripping the lifted article. In the initial position, the slider 3 of the latching mechanism is fixed (the gripping arms are in the lower intermediate position relative to the frame), while the levers 6 and 7 are divorced, see fig. 1). . Capture works as follows. Suspended in the initial position on the hook of the load-lifting mechanism, the gripper is lowered onto the product being lifted, orienting relative to the latter by means of the guide element 1 1. When the frame 1 is supported on the product, the slider 3 moves down to the extreme position and during the subsequent lifting of the gripper by the shackle 4, the slider 3 first moves upwards with respect to the frame, in which the balance bar 10, moving upwards together with the slider 3, acts by means of hinged bars. on the levers 7. When the levers 7 come into contact with the surface of the product being lifted, the levers 6 rotate relative to the axes 8 until the walls of the product are fully compressed (see FIG. 2). In the case of different wall thicknesses of the product being lifted at the points of the clamp, the process is similar to that described above, however, first, the wall is compressed with the arms b and 7 at its greatest thickness, and then the slider 3 is stirred relative to the frame 1 upwards to complete uniform compression of the product walls in all points, which is ensured by the rotation of the balancer 10 in the hinge relative to the slide 3 (see Fig. 3). The release of the grip from the load occurs after the latter is installed on the supporting surface when the slide 3 moves down tnositelno frame 1. The cycle of successive movements of the slide 3 up and down relative to the frame 1 is provided a lock 5,

The proposed grip is reliable in operation and also provides the possibility of transporting hollow products.,
