Abstract

The invention relates to lifting equipment, in particular to a load gripping device. The aim of the invention is to improve the reliability of gripping. The load gripping device comprises articulated intersecting beams 1 and 2. The associated bars 4 with the lifting legs 5 and cams 7 for resting into beams, which leads to compression of the lifting legs 5 and compressing it when moving beams 1 and 2 under the action of tension of cables 9 and slings 11 3 silt

Description

The invention relates to lifting and transport equipment, in particular, to load handling devices.

The purpose of the invention is to increase the reliability of capture

FIG. 1 shows a general view of the load gripping device; FIG. 2 is a view along A in FIG. 1, on bi. 3 is a view along B in FIG. 1.

The load gripping device consists of a supporting body in the form of two intersecting beams 1 and 2, connected in the middle of the hinge 3 with the possibility of rotation relative to each other. Rods 4 are installed at the ends of the beams with pick-up legs 5 and limiters 6.- The booms 4 are provided with vertical cams 7 installed by means of horizontal axes 8, the end faces of which interact with the beams 1, 2, and other parts are connected with cables 9, which are connected in pairs by loops 10 to each other, and slings 11, which are also connected to suspension 12 for a lifting hook

The lifting device works as follows

The device suspended on the hook of the lifting mechanism is lowered onto the load-package of sheet material laid on the bars, and the beams 1 and 2 are manually separated so that the lifting legs 5 enclose the sheet material and their stops 6 when moving the legs 5 under the material directed towards each other in the direction of the longitudinal edges of the material. After that lift sheet material. In this case, the cables 9 rotate the cams 7 up to the stop of their end profiled surfaces at the ends of the beams, as a result of which the rods 4 with the legs 5 move up and press the sheet material to the beams. Due to the fact that the lines 9 are connected in pairs, their horizontal component force passes between the rods and point of interaction. limiters 6 with the edge of the sheet material, which provides its

displacement of the ends of the beams to compress the sheet material in the transverse direction and the immobility of the rods 4.

After the material is moved, it is lowered, the rods are rotated 90 ° so that their paws 5 are out of the material, and the device is raised.
