FIELD OF THE INVENTION The invention relates to lifting and transport engineering, in particular to the tongs.

The aim of the invention is to improve the reliability of the grip.

FIG. 1 shows a tick-borne grip, general view; Fig. 2 shows the mechanism for fixing the position of the gripping organs of the tick-borne gripper in the initial position; in fig. 3 - the same, when lifting a load; in fig. 4 - the same, at the time of installation of the load on the support.

Tick-borne grip contains crossed two shoulders levers 1 and 2 connected between each other by hinge pins 3 and 4, an earring 5. At the lower shoulders of two shoulders levers are hinged gripping members 6 connected to the lower shoulders of levers 1 and 2 with additional hinge joints 7. At the end of the lower arm of the lever 2 on the axis of the hinged bracket is a strip 8, made with side parallel guides 9 and 10, one of which 10 is elongated and has a bent end. A pawl 12 is fastened between the guides 9 and 10 on the free end of the bar 8 on axis 11. A counterweight 13 is fixed on axis 1, and a counterweight 14 fixed to the first end of the bar 8, which interacts with the hinge 15 of one of the pullers 7 . The finger 16 is rigidly fixed on t 4;

Tick capture works as follows.

In the initial position, the finger 16 is in the throat of the dog 12, while

under the action of the counterweight 13 zanummet initial inclined position. Upon further upward movement of the earrings 5, the levers 1 and 2 press the gripping bodies 6 to the load, and the latter rises,

When the counterweight 14 rests on the hinge 15 and moves along it, ease of movement is ensured by the presence of the rotating sleeve 17 on the halfway 15. When the weight is set and the earring 5 moves down, the finger 16 moves down along the guide 10, then along the surface of the pawl 12 and along the guide 9. During the subsequent movement of the earring 5 upward, the finger 16 falls into the mouth of the pawl 12, the grip is removed from the load.

Claims (1)

Invention Formula Tick-borne grip containing intersecting two shoulders levers, the upper shoulders of which are interconnected to each other and with a hoop for a lifting machine hook, are hinged with 1 t of arms, and on the lower shoulders are gripped grip bodies connected by additional hinge rods to the lower arms of levers, and the fixation mechanism the position of the gripping organs, which includes a hingedly mounted on one of the double-arm levers, one end of the bar with a finger-throat fixed by an axis on its other end, characterized in that, in order to increase reliability, strap hinge pin fixed to the end of HtHcHero 45 gripping bodies 6 are divorced and fixed Q of the shoulder of one of the levers; the finger is stiffened in this position. After placing the weight on the lowering of the earring 5, the levers 1 and 2 move the rods 3 and 4 down, and the finger 16 comes out of the opening of the doggie 12, and the protector 14 turns the bar 8 and presses the guide 10 to the finger 16, and the dog 12 under the action the counterweight 13 overlaps the section between the guides 9k 10. When lifting the earring 5 finger 16 moves up the rail. 10 and acts on dog 12, turning it. After the finger 16 leaves the plank 8, the counterweight 14 rests on the hinge 15, and the dog 12 ,-,50 It is attached to the other lever, the bar itself is made with parallel side rails, one of which is made elongated and with a curved end away from the other one, and the axis of the pawl is located between them below izba, and the grip is supplied with two counterbalances , rigidly fixed one on the axis of the dog, and the other on the first end of the tank, perpendicular to it, and with EOS-. the ability to interact with the outer end with the hinge of the attachment of the opposite supplementary traction with the gripping body. 45 Q shoulder of one of the levers, a finger gesture 50 It is attached to the other lever, the bar itself is made with parallel side rails, one of which is made elongated and with a curved end away from the other one, and the axis of the pawl is located between them below izba, and the grip is supplied with two counterbalances , rigidly fixed one on the axis of the dog, and the other on the first end of the tank, perpendicular to it, and with EOS-. the ability to interact with the outer end with the hinge of the attachment of the opposite supplementary traction with the gripping body.  Rig.2 9i, z 9u2.
