Abstract

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, load gripping devices, mainly for gates of hydraulic structures. The gripping body of the load gripping device comprises a finger 4 mounted in the housing 9 in the saddles 10 and 11. In the saddle 10, the finger 4 rests on an annular protrusion 6 with rounded edges. The housing 9 is suspended to the gripping device by means of a lever mechanism 16 with a drive 17, and the finger interacts with the suspension 1 and the eye 3 of the load. When the load is seized and lifted, the finger 4 is self-set relative to the suspension and eyelets, which eliminates the concentration of loads on the elements of the device and thus increases the reliability of its operation. 4 silt; "O) oo 4 C5 sd 05 yu

The invention relates to elevation, low (not shown). In this case, the suspension

technical constructions. 2 directly on the suspension. The purpose of the invention is to increase the th mechanism. As an example of pozhnosti in the work of the gripping organ. The placement of the housing 9 on the lever Fig. 1 shows the device, the nominal feeder 16, which

general form; Fig. 2 is a sectional view. A-A is calibrated by a hydraulic cylinder 17. Fig. 1; fig.Z - section BB nafig. The device operates as follows: FIG. 4 - the end position is triple-time.

Thus, the finger is set in the vertical plane. If the gap l is larger than the turning finger to a horizontal position, then the finger 4, under the action of the eyelet 3, turns around the groove 12 until it rests on the lower landing surface, then the surface of the left suspension eye 1 and some gap remains between the edge 13 and the finger 4. In this case, the finger rests on the part of the pair of suspension 1 and the body 9 (through the support 10), which is unacceptable because it requires the body 9 to be designed with the load from the weight of the shutter. In the proposed body of the gripping body is made of the calculation of the load from the weight of the finger 4.

Finger alignment in the horizontal plane is provided by the cylindrical nature of its seating surfaces. After the shutter is maneuvered and the load is removed, the finger returns to its original position under the action of the load 8, the limiting pins 14 and 15, the guide surfaces of the saddles 10 and 11 and the grooves

Claims (1)

The invention makes it possible to increase the reliability of the coupling device by ensuring that the initial position of the finger in the housing remains unchanged and to increase its durability due to the elimination from its structure of elastic elements that change their physical characteristics of the elements as the operating conditions change. Claims of inventive pickup body 15 devices mainly for hydraulic structures gates, comprising a housing with a cantilever positioned therein and with the possibility of self-aligning fingers for interacting with 2Q with lugs of cargo, characterized in that, in order to increase the reliability of operation, it is additionally equipped with limiting pins fixed on the body and two 25 m seats for the finger, one of which is made with a wedge groove, while in the middle part of the finger an annular ledge with rounded edges for interacting with the wedge. 30 with a new groove and restrictive pins, and a counterweight attached to the non-working end of the finger.
