Definitions

  • the invention relates to a bucket attachment for a forklift truck according to the preamble of claim 1.
  • Such a known scoop attachment for a forklift truck is mounted on the front mounting plate of the forklift truck and moved by the forklift truck.
  • the bucket is actuated hydraulically by controlling the tilting movement of the bucket by means of additionally installed hydraulic cylinders.
  • the actuation of these additional cylinders is integrated in the hydraulic control system of the forklift.
  • an additional operating lever for the tilting movement of the bucket is arranged in the operating area of the forklift for its various forklift functions.
  • Such scoop attachments for a forklift with the associated hydraulic systems for actuating the scoop can only be carried out by the manufacturer of the forklift or according to his plans and can also only be designed for one type of forklift.
  • the underlying object of the invention is therefore to develop a bucket attachment for a forklift truck according to the preamble of claim 1 so that it can be used in conjunction with existing forklift truck types without having to make structural changes to the forklift trucks.
  • the hold-down device In the blade attachment according to the invention, due to the purely mechanical actuation of the blade, no hydraulics are required to trigger the tilting movement of the blade and to return the blade.
  • the hold-down device To trigger the tilting movement, the hold-down device only has to be actuated so that its locking is released with the shovel.
  • the return tension spring is tensioned, so that the bucket automatically returns to its starting position after emptying via the return tension spring and is locked there again by the hold-down device.
  • the bucket attachment can be attached to any type of forklift truck without having to make any structural changes to the forklift itself.
  • Fig. 1 is a rear view of the embodiment of the forklift according to the invention.
  • Fig. 2 is a sectional view taken along the line A-A in Fig.
  • Fig. 3 is a side view in the direction of arrow A in
  • Fig. 4 is a bottom view in the direction of arrow C in Fig. 1 and
  • FIG. 5 is a side view in the direction of arrow B in FIG. 1st
  • the embodiment shown in the drawing of the scoop attachment according to the invention for a forklift essentially comprises a scoop 11 which is held in a holder which can be pivoted or tilted about an axis and which comprises a base frame 2, for example in the form of a base plate, which also includes Recordings 1 is provided for the forks of the forklift.
  • the receptacles 1 for the forks are arranged and dimensioned so that the bucket attachment is suitable for all types of forklift trucks.
  • Buckets of various designs can be held in the holder, which are pivotably, rotatably and in particular tiltably mounted on the base frame 2.
  • a hold-down device 4 is attached to the base frame 2 and serves to lock the blade 11 in its horizontal position. As is shown in particular in FIGS. 2 and 5, this hold-down device 4 consists of a vertical stand which can be pivoted about an axis in its foot part and which projects in the direction of the blade 11 on projecting part of the beveled pawl element 14 is provided, over which a locking element of the blade 11 can slide and engage.
  • the hold-down device 4 is acted upon by a spring 10, which prestresses the hold-down device in the direction of the locking position.
  • Hold-down device 4 attached, which leads into the driver's cab of the forklift truck and on which the driver of the forklift truck can pull in order to release the locking of the bucket 11 on the hold-down device 4, in that the hold-down device 4 counteracts the force of the spring 10 from engaging with the Blade 11 is withdrawn.
  • the hold-down device 4 can be designed in such a way that its rearward movement leads to a slight pivoting movement of the blade 11, which is associated with a shift in its center of gravity. This pivoting movement of the blade 11 can be triggered or effected via an additional lever. This shift in the center of gravity triggers the tilting movement of the blade 11 downward.
  • the shift in the center of gravity can also be supported by slightly tilting the forks of the forklift downwards.
  • a return spring 6 is provided between the blade 11 and the holder, which is provided with a turnbuckle 7 for adjusting the return force and is tensioned downward by the tilting movement of the blade 11. • the return force of the return spring 6 is so chosen that the empty bucket is returned after the tipping 11 to its initial position for locking by the holding-down device. 4
  • the locking device of the hold-down device 4 can be designed so that the locking takes place automatically.
  • guide rods with adjustable stops 8 for setting the maximum possible tilt angle of the blade 11 are provided such that they limit the tilting movement of the blade 11. These stops 8 and thus the maximum possible tilt angle are adjustable.
  • a stop damping 9 on the rings 15 sliding on the guide rods, which are attached to the blade 11, serves to dampen the stop 11 when the tilt limit angle is reached.
  • the fork tines can be retracted into receptacles 1 of the base frame 2 of the holder for the blade 11.
  • Knebel ⁇ screws 3 which are provided on the base frame 2, serve to secure the fork tines against slipping.
  • the embodiment of the bucket attachment for a forklift according to the invention described above is used and used in the following manner.
  • the bucket attachment is attached to the forklift so that the forklift tines move into the receptacles 1 of the base frame 2.
  • the bucket attachment and the fork tines are secured against slipping via the toggle screw 3.
  • the forks in the base frame 2 are basically picked up in the same way as the forks in a pallet.
  • the rope 5 for triggering the hold-down device 4 is hung on the lever 13 for actuating the hold-down device and guided into the driver's cab of the forklift.
  • the forklift driver releases the locking of the shovel 11 on the hold-down device 4 from his driver's seat with the aid of the pull rope 5 by pulling on the pull rope 5, whereupon the shovel 11 tilts downward about its pivot axis.
  • This tilting movement can be supported by shifting the center of gravity when releasing the lock with the help of a lever or by slightly tilting the forks of the forklift downwards.
  • the two guideways with their adjustable stops 8 limit the tilt angle and enable damping of the stop via the stop damping 9, for example in the form of compression springs.
  • the return spring 6 is tensioned so that after the blade 11 has been emptied, the blade 11 is pulled back into its starting position, in which it is automatically locked again by the hold-down device 4.
  • the Locking the bucket 11 automatically snaps back into place.
  • the scoop attachment according to the invention for a forklift truck thus has the advantage that only mechanical elements are required for its operation, so that it is suitable for use with all types of forklift trucks without any structural changes, for example additional hydraulic or other, on the forklift trucks themselves Control devices must be provided.

Abstract

Fixation de pelle pour chariot élévateur à fourche comportant une pelle (11) montée pivotante sur un cadre de base (2), dans laquelle les fourchons du chariot élévateur à fourche peuvent être retractés. Un dispositif de fixation (11) retient la pelle (11) dans sa position horizontale, et un ressort de tension de rappel (6) sollicité lorsque la pelle (11) s'incline vers le bas ramène la pelle vide à sa position horizontale où elle est à nouveau retenue par le dispositif de fixation (4). La rétention de la pelle (11) par le dispositif de fixation peut être débloquée à partir de la cabine du conducteur du chariot élevateur à fourche au moyen d'un câble de traction.
