Description

one

The invention relates to transport and add-on equipment, in particular, automatic grippers for piece goods, mainly for truck cabs.

There are known automatic grippers for piece goods, including a traverse with gripping hooks, which interact via a lever system with a device for fixing the position of the gripping hooks, and a pulling link.

The purpose of the invention is to reduce the working stroke of the pulling earring, the weight and dimensions of the automatic grip. This is achieved by the fact that on the traverse of the gripper there are installed two-arm swinging arm-levers, connected with a pull earring, at the ends of which are pivotally fixed pushers interacting with the hook arms attached at the ends of the traverse with hook levers, two-arm clamps and spring-loaded profiled levers.

To limit the stroke of the rocker arms, the rocker arms, when the gripper is working, traps with height-adjustable stops can be installed on its traverse.

FIG. Figure 1 shows the onisable grip, side view; in fig. 2 - the same plan; in fig. 3 - the same, in different positions; and - before zahzahvat and lifting; b - during the seizure of cargo; in - when transporting cargo; d - during the installation of the cargo.

The automatic gripper contains a traverse 1, at the ends of which two gripping hooks 2 are hinged. In addition, two two shoulders of the rocker arm 6 are connected to the traverse 1 and are connected to each other by means of hanging-hookly cepbroii (ring) 4. At the end of each lever 3, they are hingedly fixed pusher about. 1 alternators alternately act on the lever 6 of the hook 2 and the clamp 7 pivotally fixed on the yoke 1. In cooperation with the pusher o and the clamp 7 there is a lever 8 pivotally fixed

on the yoke 1, on which the spring 9 is raised. On both sides of the earring 4 to the yoke 1, brackets 10 are fastened with bolts 11 for adjusting the stroke of the levers 3. The hooks 2 are rigidly connected to the levers 6. Inner arm

lever 3, if necessary, may be additionally supplied with a load 12. The sequence of action of the pusher 5 depends on

the positions of the lever 8. The pusher 5, the latch 7, the lever 8, the spring 9 and the outer arm of the rocker arm 3 constitute a kinematic mechanism for alternating the locking and unlocking of the gripping bodies and are not loaded with structural elements. Cargo carriers

elo are traverse 1, hook 2,

3

The inner arm of the lever 3, the carrier bar 4 and the clamp 10 with the adjusting bolt 11. When adjusting the grip adjusting bolt 11M the bolt 11, the stroke of the lever 3 is adjusted so that the mechanism for alternating the fixation of the gripping bodies to avoid breakage would not absorb the load from the rod and resize it. 1U.

The gripper, which is ready for the load, is in a position higher than the hook position of the load lifting mechanism. In this nozhodeini, the gripping hook 2 is nodal by means of pushing the lever b from above onto the lever 6 of the gripping hook 2, which, in turn, acts on the clamp 7 and removes the lever 8 into a more vertical (vertical) position and function. For the seizure of cargo, the seizure is onus of the cargo. At the same time, the internal forces of the levers 6 of the node, with their own weight and load 12 (the inner arm of the levers 3 must be significantly larger than the outer), are directed to the traverse and the outer arms are attached. At the same time, the catch hooks 2 are released and, on the contrary, the strongest load is required. Then, when the load is captured, I begin to locate it. The levers 3 are in turn rotated in turn, during which their inner legs are knocked up until they are aligned with the adjusting bolt. And the restraint speed 10, and the outer arms are coupled with the retracted light nrulsins (not shown in the drawings) to the center of the ram 5. Pushers 5, onuek, leverage the 6 gripping hooks 2 and, pressing the latches 7, pull them out of the arms of the levers 8, turn and tighten the latches 7 so that the external Ilechi SI nodnmayuts, nodiirayut and fix the levers 6 hooks 2 in the working no. In this way, the further load grab unit is built up and is lifted together with the gripper.

The levers 8 remain unlocked. Next, the cargo is transported. When installing the load, the onor is first lowered onto the load of the traverse 1, and after that the lia of the traverse is lowered, butt in the hinges, the inner shoulders of the levers 3, at the same time, their outer shoulders. When this spring-loaded levers 8 squeeze out and hold the pushers 5 above the levers 6

gripping hooks 2. With the subsequent lifting of the gripper, the lever 3 is turned, and the pushers 5, on the top, press down on the arms of the gripping hooks, turning them to the sides and freeing the load from

capture. After that, the gripping takes the position of readiness for slinging the next load, and the cnl is repeated.
