Pincer gripper for the transport of workpieces

The invention relates to a rrsi- a locking and release device equipped gripper for transport

η workpieces, in which the two at over Gehär. ; lashes, shackles or the like in the load hook of a üe -bezeuges eiiihangbore pull straps hinged Zanyen bar! connected by zv: ei horizontal flaps over gelei'ik-äolzen rai ti: in <i! V.ter bind. Pincer grippers of this type (DT-PS 1 b'5'ύ 2.15) can be used on the workpieces to be transported ir.ur.er hcciaontal auisav. ζ and serve your transport of a workpiece. ".

The invention is based on the object of providing a transport device which has several identical ones at the same time Profile bars, preferably railroad tracks! to transport allowed. To transport such professional pieces are so-called. Rails were known as single-bolt pliers, also bow-i called pliers, are designed and by means of chain rings a crane or a traverse. If several rails are to be transported at the same time, then earth them several soJ rather rail clamps attached to a traverse. ' The disadvantage of this rail zango.n is that r.ie manual! opened and inserted over the heads of the rails. ;

The above-mentioned object is erfindun.gsgeni.- ^; ..C solved by the fact that at the free end of each Zangonschmkcls of the aforementioned: pincer gripper a hinge pin fixed ir, t, the Lor

This is achieved by virtue of the fact that the pincer gripper in its locked position is also aligned parallel to one another at a distance from one another

Below the hook attachment 20 ', an inclined surface 21 is provided on the same pliers tab 1. The individual parts are designed or mounted in such a way that the hook 17 of the lever 14 can be moved behind the hook attachment ^{20 1} of the locking hook 20 in order to lock the pliers in the open state (FIG. 1). The tongs can now be placed on a workpiece to be transported. The locking of the pliers parts is then still retained for the time being. If you now lower the crane hook to which the gripper is attached, then the hook 17 of the lever 14 slides along the inclined surface 21 / is thereby pivoted, whereby the projection 15 lifts off the stop 16, and the latch 19 to System on the hook attachment 20 'of the locking hook coitmt. The pliers parts are now unlocked. If the shackle 11 is now raised, the pliers legs 2 and 3 grasp a workpiece to be transported.

When the point at which a workpiece is to be set down is reached, the crane hook and thus the shackle 11 are lowered and the tong legs open when the crane hook is further lowered. When it is still further set down, the hook 17 of the lever 14 slides on an inclined surface 20 ' ^! of the locking hook 20 along and then engages behind its hook attachment 20 ', whereby the

The carrier 25 closest to the viewer in FIG. 1 has hooked noses 2 4 directed to the right, and the dome viewer ab- '. facing carrier 26 hooked noses 2 4 directed to the left. j

If the pincer gripper is raised from the position shown in FIG. 1 after its locking and release device has been unlocked, the free ends of the pincer legs 2 and 3 and thus also the two hinge pins 22 and 23 approach each other, whereby the carriers 2, 4 and 25 are shifted against each other in the horizontal direction so that each hook nose 2 4 of each carrier 2b or 26 engages behind the heads of rails 35, whereby the rails can be grasped and transported by the pliers gripper. Of course, at least 2 pincer grippers of the same type are used in order to be able to move the rails to be transported in a horizontal position. ;

In order to prevent the pincer gripper from tilting when transporting rails, it is necessary to put on the hinge pins 22 and 2 3
