Description

Single-rope myomaxillary grabs, in which the unloading is carried out when the protruding elements of the grapple interact with the bell suspended from the crane, are known. Such grabs do not provide the possibility of unloading rpeikj) epa at an arbitrary height.

In the proposed grab, this disadvantage is eliminated by the fact that the traverse of the grapple is connected when a randomly controlled spring-loaded retainer is trash.

FIG. 1 shows a general view of a grapple with closed self-enclosures; pas figs. 2 is a longitudinal section; in fig. 3 shows a grapple at the end of the jaw opening; in fig. 4-at the beginning of the jaws; in fig. 5- at the end close the jaw) ;; in fig. 6-at the beginning of the jaws; and FIG. 7 and 8 are the layout of the blocks in the grapple in two projections.

The jaws 1 of the grapple (Fig. 2) are hingedly attached to the lower tracker 2 and, using 5 to the upper traverse 4, fitted with a reinforced block on it 5 and directional rollers 6 for the rope 7. At one end, the rope is attached to the upper traverse 4 and bends around blocks 9, J and S (see Fig. 7 and 8). On the middle traverse W (Fig. 2), the pivot hook was strengthened //, the interaction of U1tsi 1 with the hook 12. fastened on the lower traverse 2. In the hooked state, the hooks // and 12 hold | c; tc clamp in the form of a spring-loaded doggie 3, Iodine action of a spring-loaded rod 14 connected with a two-arm lever 15 controlled by a cord 16. Middle and upper; the ravers are also interconnected by two telescopically sliding rods 17 (Fig. 1).

The grapple with its open jaws is suspended with the power of the rope 7 to the load hook of the lifting edge. In this case, the intermediate 1-span 10 (see Fig. 3) is brought to the upper cross bar 4. iB such a grab is lowered and the material being overloaded. In order to fill the grapple, it is necessary to loosen the tension of the hoisting rope 7, (fig. 4), as a result of which the middle yoke 10 will begin to descend to the h:

hooks // and 12. Dog 13 clamp will lock them in this position. After further tightening of the rope 7 (fig. 2, 5) middle traverse 10, lift up, there is no sweat behind the coooii lower traverse 2, and the jaws / will close and capture the material to be loaded until the grapple is completely detached.

The filled grab moves to the place of unloading and stops above this place. . For 1, the harbor is pulled and tensioned from the control zero of the crane 16 until the refusal (Fig. 2, 6) and at the same time do not lose, 1) The distance is lowered by the grapple. The rod 14 of the pn is the dog squeezes out; 1 at 13, its lower position and the closing hooks 11 and 12 are freely disengaged. This middle traverse 10 rests on isepxHioK traverse 4 and the lower traverse 2 rests on iodxHioK. Decreasing its own weight and .mat |) na.1a goes down, simultaneously opening the jaw /. When it is located, the obverse 2 guides the bristle with their upper end abutting the spring amorticator enclosed in pipes, and thereby contribute to the softening of the sharp jerk at the moment of full opening of the jaw.

Then the crane operator releases the cord 16, the clamping dog 13 takes up the action of the spring c; k; e is the upper position and the grapple lears behind the new rate of material.

ADDITIONS AND INVENTIONS

1. Odnokanatnyi Gg. M are gogoche.lyustny g grab, consisting of the bottom and BepxHOii traverse, to which the first one is fixed, and the average of the grab, and the average of the gantry.O11 on the cr () to the crane, zanno1 g noj HC iacTOM with traverso) p with, e l emo ipn omop, and from the bottom grass, about t, 1 and h ay I, and the fact that, in order to ensure the possibility of splitting: t 1 gre | Sphere and weight, hooks one on the middle, and torpedo: - and on the lower traverses and held in a set condition, the weakness of the weakness in the electrified 1: one arm of the latch.
