Description

(54) TICK-UP CAPTURE

The invention relates to loading and unloading operations, in particular to load handling devices.

Known tick capture, content- ;; The glue of the devine glue hinged to each other and hinged on the hook of the load-lifting machine and the glue-lock fixation mechanism in the open position, includes a stand made of two cheeks, one of which has a groove with two guiding bevels, and a swivel bracket with a finger, the entrance scht. 1 in pa, s rack l.

However, the known device is not sufficiently reliable in operation.

The purpose of the invention is to increase the reliability of work.

The goal is achieved by the fact that the tick grip is equipped with a hinged fastener; hinged snaps one on another on the cheeks, and; arnirno. connected together by a hard thrust, interacting with the finger strap and anchors fixed to the cheek, the groove has a vertical portion, the guide bevels are located relative to it at an angle of 45 ° and relative to each other at an angle of 90, and the length of the upper target is greater than the lower one by the diameter of the weave's finger.

Pa of figure 1 shows Obadium a tick-borne capture in the initial position: in figure 2 - node 1 in figure 1; in FIG. 3, view A in FIG. 2; figure 4 - the mechanism for fixing castors in the open position at the time of entry of the bracket into the groove of the rack; figure 5 - then

10, at the moment when the finger staples through the vertical section of the groove; 6 is the same at the time of the fixed fixed position of castors.

Kleschevoi.Zakhvat contains castreaders 1 that are hinged together and a casting mechanism in an open position that includes a pivot bracket 2 with a finger 3, a ball 20 mounted in a frame 4 which is interlocking with the stopper 6, and a stand made of two cheeks: the front 7 and back 8. In the front cheek 7, there is a groove 9, having 1: the central vertical section and the direction of the bevels 10 and 11, located relative to it at an angle of 45 and relative to each other at an angle of 90®. On the cheeks pivotally

30 are fixed by means of axles 12 and 13 and are located one above the other lower 14 and upper 15 latches, which are nominally interconnected by means of a rigid rod 16 and cooperate with fixed stops 17 and 18 on the cheeks and 3 fingers with the finger. The screws 5 are larger than the lower 14 by the diameter of the finger 3 of the bracket 2, and the latch 14 is connected to the spring 19. The clamp bar works like an ohm. When lowering the tick-borne grip on the load, its frame 4 begins to touch the load; parallelogram suspension grip under the action of its own weight is folded, and with it the cheeks 7 and 8 begin to fall together with the latches 14 and 15. When moving in the vertical groove 9, the finger 3 of the swivel bracket falls on the bevel 11, and then on the bevel 10, the swivel bracket deviates from the vertical position, extends from the cheeks. 7 and 8 and is returned to the vertical position by the spring 5 (Fig. 2). In this position, the tick-borne grip takes the load and carries it in the right direction. When the load touches the support parallel to the frame, the grip suspension begins to fold and the finger 3 swivels the strap 2 falls into the vertical S acTOK groove 9, deflects upward the lower sight 14, extending the spring 19, and the upper latch 15 deflects also upwards due to the thrust 16 to the stop. 17. By rejecting the latch 14 completely and passing it, the finger 3 of the swivel bracket 2 falls into the zone of action of the two latches 14 and 15 (Fig. 5). In this position, when the parallelogram suspension is further folded, the finger 3 of the swivel bracket 2 abuts against the latch 15 (fig.b), since the length of the upper latch is longer than the bottom, and when the lower latch is released 14 with the finger of the swivel bracket 2, it will return with a spring 19 to the initial position and to carry away the upper latch 15 with the help of the tipper 1. The movements of the latches 14 and 15 in this position are shown: by the radii with the arrows of rotation about their axes (Fig.5). Moving upward, the finger 3 of the swivel bracket 2 is held by the latch 15, so that the tick-breaker pawl pin is precisely fixed, and the finger of the swivel bracket 2 cannot pass upwards along the vertical portion of the groove 9 (Fig. 6). Freed from the load, the clamp grip begins to rise, the parallelogram suspension is extended, the pivot bracket 2 with the finger 3 starts to fall down, releasing the upper latch 15, thereby spring 19 is compressed, returning the latch 14 to the closed position until it stops 18. Finger 3 of the pivot bracket 2 is lowered onto the latch 14 and the entire grip is opened to the desired point of operation. In the future, the cycle of operation of the load gripping device is repeated. This tick-grip design provides an accurate delimitation of the tact of opening and opening castor beans, which increases the reliability of its operation. Claims of the invention A tong clamp that contains hinges that are pivotally interconnected and a castor hung on a hook of a lifting machine and a castors locking mechanism in an open position, includes a stand made of two cheeks, one of which has a groove with two guiding bevels, and a swivel bracket a finger, which enters the slot groove, characterized in that, in order to ensure the reliability of operation, it is provided with hinges that are hinged one above the other on the cheeks, hinged between each other The finger interacting with the staple and anchors fixed to the cheek, the groove has a vertical section, the guide bevels are located relative to it at an angle of 45 ° and relative to each other at an angle of 90 °, and the length of the upper latch is larger than the lower one by the diameter of the pin finger.
