Description

GERMAN

There are already grippers for moldings and the like known, which are operated by means of compressed or suction air, or in special cases on documents (so-called Pallets) made of metal or wood are used on which the stones to be transported are placed will. Compressed air or suction air operated grippers could only be installed on forklifts which in their design already have an additional pressure cylinder for hydraulic gripper actuation were equipped. Thanks to the hydraulic gripper device located at the bottom of the floor, which the is exposed to accumulating dirt and clay dust, however, operational malfunctions occurred continuously.

The inventor has set himself the task of eliminating all these disadvantages by a mechanical or Hydraulically operated knee joint gripper holding device in forklift trucks for bricks or the like Shims according to the invention is formed in such a way that the gripper and holding device consists of three Skids, of which the middle is fixed, while the two outer ones are adjustable with one Ouertraverse are connected, the middle and one outer runner against spring action from the rest position have protruding pressure rollers or pressure plates made of rubber or other material.

According to a further idea of the invention, the thrust axis is protected in an I-profile iron Runners stored, the knee joints with the pressure rollers when moving the thrust axis out of the runners step out sideways.

In the drawing, the essence of the invention is for example and illustrated schematically, and. although shows

Fig. 1 is a side view,

Fig. 2 is a plan view,

Fig. 3 a detail of the knee joints with pressure roller, thrust axis and working springs.

On a cross member 1 attached to the telescopic carriage of the forklift are three parallel runners 2 attached at an appropriate distance, in the cavity 3 one with knee joints 4 and pressure roller 5 and working spring 6 equipped thrust axle 7 protected in bearings, not shown, displaceable is stored.

The runners 2 have openings on one or two sides or cavities 3 through which the knee joints 4 with pressure roller 5 emerge when the working spring 6 is released, while the other sides of the runners 8 remain closed and are provided with retaining lugs 9. The cams act on the thrust axis 7 12 of a shaft 13, which are rotatably held in bearings, not shown, and about the handlebar 14, connecting rod 15 and hand lever 16 is rotated. A latch 17 locks the hand

Lever 16 and thus finally the one put out of action by bolt 10 (Fig. 3) via link 11 Working spring 6 on thrust axis 7, so that the knee joints 4 with pressure roller 5 in the cavities 3 of the Step back on skids 2 (see dashed position of pressure rollers 5).

The operation of the device according to the invention is as follows: If the stone pile with the Support blocks 18 are to be picked up, the lever 16 is first operated hydraulically or by hand the trap 17 released and lifted.

On the hand lever 16, the connecting rod 15 is mounted so that it can move in height, which is connected via the handlebar 14 the shaft 13 engages and rotates. The latter carries cams 12 against which the Thrust axis 7 engages by the working spring 6.

Due to the action of the working spring 6, the link 11, with which the knee joint 4 is movable is connected, axially pushed together, whereby the pressure roller 5 from the opening 3 of the runner 2 laterally steps out.

By stepping out of the pressure roller 5, the base blocks 18 are clipped against the ones with retaining cams 9 Skid side 8 pressed on and released again when the hand lever 16 is moved in the opposite direction.
