    A lifting device for filled sacks comprises a frame in which a pair of parallel clamping bars are mounted to be revolved in unison by a crank about a common horizontal axis parallel to and spaced from the longitudinal axes of the bars. One of the bars is individually rotatable about its own longitudinal axis and is displaceable towards and away from the other bar. The gathered top of a sack is introduced between the bars when these are separated and automatically becomes wrapped around the bars and clamped therebetween as the crank is turned, whereafter the sack can be lifted by raising the frame.

    one
    The invention relates to lifting equipment, in particular, cargo handling devices for filled bags.
    A device for gripping b and lifting filled bags, containing a carrier element hung on a hook of a lifting mechanism, and two clamping rods 1 are known.
    However, the known device is sufficiently time-consuming to operate.
    The purpose of the invention is the convenience of operating the device.
    The goal is achieved by the fact that the device is equipped with 16 articulated axles connected by means of horizontal axes with bearing element with two vertical cheeks, in which the said clamping rods are fixed, with one rod fixed with the cheeks rigidly, and the ends of the other are installed in oval grooves made in the cheeks, with the possibility of peremshtseni towards the fixed rod.
    In addition, a handle can be fixed on at least 25 of one horizontal axis to rotate the cheeks with sucker rods.
    A clamping rod secured in the oval grooves of the cheeks can be supplied with
    wives at the ends of the trunnions located in these slots.
    Figure 1 shows the proposed device; Fig, 2 - zhb, side view; on fig.Z - section aa of figure 1, after a half turn of a pair of clamping rods; figure 4 is the same, after a complete turnover of a pair of clamping rods; figure 5 - node 1 figure 2; figure 6 - node II fig.Z figure 7 node III figure 4.
    A device for gripping and lifting filled bags comprises a carrier device 1 with a central point of suspension 2, which can be gripped by a crane tail (not shown in the drawings). The carrier device 1 is rigidly connected with straps 3 and 4, provided with holes 5 in which axles 6 are rotatably mounted. The outer ends of the axes 6 are rigidly connected with the handles 7, and the inner ends with vertical cheeks 8. There are clamping rods 9 between the cheeks 8 and 10, one of which is rigidly connected with both cheeks by both jokes 8. The clamping rod 10 has cylindrical pins 11 at both ends, which are installed with the possibility of movement in the oval grooves 12 cheeks 8. Thanks to
    the cylindrical design of the filler cores, they can rotate around themselves. The grooves 12 are directed towards the clamping rod 9 so that both the clamping rods 9 and 10 can be in contact. The cheeks 8 for inserting the BejpxHero end 13 of the lifted bag are rotated in such a way that for the bottom 13 end of the bag inserted the maximum possible wide opening between the two clamp rods 9 and 10 and the connecting line between the two flexible rods takes almost horizontal position. At the same time, the axis of rotation passing through axis b lies above this connecting line. After inserting the end 13 of the bag, the handle 7 is rotated so that the movable clamping rod 10 moves over the stationary clamping rod 9. Fig. 3 and b show the position after rotation in the right direction by 180. After further rotation in the same direction, the following 180, the position shown in Figures 4 and 7 is reached. Due to the tension force, the movable clamping rod 10 approaches the stationary lock rod 9. And at the same time, it turns in such a way that the end is wound onto it. The end of the bag is secured by the double wrap around the pressing rod 10 and, in addition, Of is clamped between the clamping rods 9 and 10.
    The perpendicular 13 through the center of the bag's sheet metal in the end position shown in Fig. 7 lies between a certain axis 6 of the axis of action and a movable rod 10. The horizontal distance between the perpendicular 14 and the axis of rotation
    between perpendicular and spread
    The rum 14 and the axis of the clamping rod 10 are established after reaching an equilibrium position, which is determined by the force applied through the axis of rotation, the weight of the machine, and the torque generated by the distances a and b. Moreover, in the state of equilibrium it is |
    the moment from the force and distance applied on the axis of the axis is equal, but oppositely directed to the torque from the weight
    b
    bag and distance
    Due to the position reached by the E end state, stable and reliable lifting of the bag is made possible.
    If the walls are thicker than shown in Figure 7, then the state of equilibrium is established even before the end of the rotation of the cheeks 8 by 360, TciK as a distance b more than this is shown and for this the spreading should increase.
