Description

(54) FORK CAPTURE

  The invention relates to lifting and transport equipment, in particular for the transport of packaged piece goods having different overall dimensions.

On the main auth, sv. No. 647227 is known forks, containing vertical uprights with clamping stops, horizontal traverse with stops. On which the spring-loaded pivot forks with folding levers, interacting with stops til.

Its disadvantage is the need for manual retuning of adjustable clamping stops when capturing loads of various ramer.

The purpose of the invention is to reduce the scope of application by ensuring the capture of loads of various sizes without additional reconfiguration. t

This goal is achieved by the fact that the clamping lugs are fixed on the vertical uprights by means of toothed racks spring-loaded with respect to them, while the grip is provided with guides arranged on the vertical uprights and located in them interacting with the strips of anchors connected by lower

with their ends with forks made in the form of two shoulders levers.

FIG. 1 shows the proposed grip in the unloaded position; in fig. 2 - the same, with a load.

The grip contains two paral racks 1, rigidly connected to each other and hung on a hook 2, for example, an overhead crane. At the bottom

10 parts of the rack bear the yoke 3, on which the forks 4 are hinged. They are made in the form of two-arm levers having shoulders 5 and 6. By the hinges 7 are attached to the shoulders 5 by means of hinges 7

15 folding levers 8, which interact with the stops 9 traverse 3,

In the middle of the fork 4. installed us spring 10 in contact with the crosshead 3,

20

In order to provide the possibility of transporting goods 11 having different overall dimensions, in the middle part of the vertical supports of the arms

25, clamping lugs 12 are arranged, mounted on spring racks 13 which are spring-loaded in the direction of the gripped load by springs 14 arranged in horizontal guides 15,

The latches 16, which are fixed on the arms 6 with the help of hinges 17, interact with the laths 13, and are located in the railings 18.

For the grip to work, the side surface A of the load is necessary,

Capture works as follows,

In the unloaded condition, the forks 4 are raised by springs 10, the shoulders 5 of the forks and the hinges 7 occupy the uppermost position above the stops 9, and the shoulders 6 with the hinges 17 are the lowest position. In this case, the levers 8 | under the action of their own weight occupy a horizontal position, the latches 16 are inserted from the engagement with the toothed racks 13 and the clamping lugs 12 under the action of the springs 14 are extended inside the grip,

The gripper is brought under the weight 11 on the supports, compressing the spring 14, and orienting it so that the side surfaces of the load are located between the stops 9 and 12,.

Then the seizure is raised. The weight of the onyc is carried on the forks 4 of the cross bar 3, the springs 10 are compressed, the hinges 7 are bowed down, the levers 8 are in contact with the stops 9 of the cross bars 3 turn in the direction of the load. Here, the grip is oriented relative to the load under the action of the spring-loaded lugs 12,

After the hinges 7 and 17 have reached their extreme positions, the clips 16 are engaged with the toothed racks 13, fixing the clamping stops 12 relative to the uprights 1, and the levers 8 occupy a vertical position, holding the load on the gripping forks.

The fork is unloaded, the load is lowered onto the stands. The grip then drops below the load. Under the action of the springs 10, the forks 4 are raised together with the levers 8. When the hinges 7 are in the extreme upper position, the levers 8 are horizontal, the anchors 16 come out of the engagement with the toothed racks 13, the Grip is ready for the next cycle of the seizure of the load.

The proposed grip will allow the seizure of goods having different overall dimensions, without additional readjustment, which will increase labor productivity and ease of operation when transporting piece goods.
