FIELD OF THE INVENTION The invention relates to a lifting and transport equipment, namely, lifting devices.

The purpose of the invention is to increase reliability.

FIG. 1 shows a load gripping device, general view; in fig. 2 - the same. plan; in fig. 3 a section A A in FIG. one; in fig. 4 a section B-B in FIG. 2; in fig. 5 kinematics of the load gripping device; pas figs. b, section B - B in FIG. 3; in fig. 7 is a view of FIG. five.

The load gripping device contains upper 1, lower 2 traverses which are interconnected by cables 3, gripping organs in the form of paws 4, vertical P1 tangu 5, made with screw 6 and vertical 7 grooves, spring 9 with spring on the springs 8.

In addition, the upper 1 and lower 2 tracks are version, AI, and aii with centering devices in the form of telescopic sleeves 10.

On the upper traverse I of the hinge, they are fixed hollow) legs 11, to the middle of which are hinged the levers 12 with rejected and 13 and hingedly connected between them. Lru1 is the ends of the levers 12 i DT versti mp 13 fixed on the upper traverse 1.

At the ends of the upper legs, the cross member 1 is installed with a possible rotation of the Collar with 14 non-interleaved sections that interact with the fittings 15. The control lines 16 are fixed to the ends of the hollow levers 11, the load points 17 are connected to the sliders 18 and the lower cross bar 2. The upper the ends of the lines 17 and 16 are connected to each other by means of the dowel 19.

Fitpngp 15 contain spring-loaded dampers 22, and the lower traverse 2 consists of two parts connected by a hinge 23, and adjustable stops 24 are installed at its ends.

Load handling device operates as follows.

The load (the axial device) is mounted on the load 25, while the lower traverse 2 through the adjustable stops 24 and the hinge 23 copies the horizontal axis of the load 25, while the vertical bar 5 rests on the lower traverse 2, and the interaction is carried out} This six and vertical 7 grooves with spring-loaded spring 8 pa.1 9, rotated clockwise b.juk 20 with a cable drive system 21, transverse to drive, rotated with 90 ° rods with variable-section heads 14. .Auto0

The slinging of the load 25 is carried out at the moment when the upper yoke stops in the lower yoke 2, while the hollow levers 11 are released from the fittings 15 with the spring-loaded dampers 22 of the upper yoke 1.

When lifting the suspension of the 19 grub-gripping device, the slings of the control b lifts the hollow levers i i until they are fixed with the upper traverse 1 lever ч 12 with the previously outdated. SECTION 13 for the given dimensions of the load 25. At the same time, cargo trucks: ii, i ,, iAi, b, i8, move the feet 4 to 1 full shaft 25, iip, i V7r7ikalnye rods 5 full upper traverse 1 in the initial position.

After transportation and shipment of cargo 25 to the storage site of the lower graver 2, the adjustable stops 24 and 1 hinge 23 copy the horizontal plane of the base of the cargo, as a result all four paws 4 are in the unloaded 25 position, meanwhile the upper traverse 1 continues lower as far as it will go to the lower yoke 2, while the screw 6 and vertical 7 slots are vertically using the cusp of Ptangi 5, they interact with the pivot pin 9, thereby implementing the ni.ec i c. 1 Egs Israel Anti-clockwise block; 20 and attached to it in the form of a cable-block system 2 rotates 90 rods from go: k) 14 ncpeve.iHorc) 0 sections in position: iobo (: rdv3; j 24.

At the same time, the cables 3 through the truss block system, fixed in the lower traverse 2, slide the sliders 18 and the legs 4 out from under the steering wheel 25, and the cargo legs 1 17 have slack. Then the cycle is repeated.
