Definitions

  • the invention relates to an actuating device for at least one hydraulic Valve of an industrial truck according to the preamble of patent claim 1.
  • Hydraulic slide valves for example to control the various Functions of a load suspension device are usually in the case of industrial trucks Arranged area of a driver's cabin, wherein a movement of the Actuating lever is mechanically transferred to the valve spool.
  • Actuators of the prior art have a complex for this mechanical linkage with which a pivoting movement of the Actuating lever is transmitted in a longitudinal movement of the valve spool.
  • GB 2 278 422 A is an actuator for one Valve slide known in which the operating lever via an intermediate lever is articulated to the valve spool.
  • Operating lever and intermediate lever are movably mounted on a battery compartment cover and are opened when the Battery compartment cover pivoted together with this
  • the present invention has for its object to provide a simple, easy to install independently of a battery compartment hood Actuator to provide the ergonomically advantageous can be actuated.
  • the operating lever is either direct or indirect, via a to the Actuator lever-attached connector, mounted on the two axles.
  • the actuating lever only has a rotary one Degree of freedom.
  • the operating lever has one rotational degree of freedom as well as a translational degree of freedom, with which a Changes in the distance of the first axis to the second axis can be compensated can.
  • Such a determination of the operating lever is, for example, by means of an elongated hole or a fork-shaped receptacle.
  • At least one Actuating lever is from an operating position to a non-operating position movable.
  • the actuating levers move while the truck is operating their operating position, whereby the positions of the actuating lever Neutral position and when operating the valve are included.
  • the axis that is not arranged on the valve slide is on one between an operating position and a non-operating position relative to the Truck arranged movable carrier.
  • the operating position or Out of service position of the carrier corresponds to the corresponding position of the Actuating lever.
  • the axis arranged on the carrier, and thus the Operating levers are moved with the carrier.
  • a driver's seat is usually located on the hood of the battery compartment.
  • the Carrier or a component rigidly connected to the carrier is in the operating position located carrier arranged so that opening of the hood is prevented.
  • the hood is thus automatic when the operating levers are in the operating position locked.
  • One of the two axes is on the valve spool or on, with the same effect a component rigidly connected to the valve slide arranged, the axis is aligned perpendicular to the direction of movement of the valve spool and thus moved relative to the valve spool when the valve is actuated.
  • the axis that is not on the valve slide is arranged during operation of the industrial truck a relative to Truck cannot change position.
  • the first axis is on the Valve slide arranged and has the second axis during the operation of the Industrial truck in a position that cannot be changed relative to the industrial truck.
  • the position of the actuating lever is thus precisely defined in relation to the valve.
  • each Valve slide is connected to an operating lever.
  • the actuating levers are expediently on a common, not on the Valve spool arranged axis mounted during the operation of the Industrial truck has a position that cannot be changed relative to the industrial truck.
  • the number of required components can hereby be compared to the known Prior art arrangements can be significantly reduced.
  • Each operating lever is still on the corresponding one Valve slide arranged axis mounted.
  • the different ones Axles arranged on valve spools cannot naturally be rigid with each other get connected.
  • the axes arranged on the various valve spools are at Neutral position of the valve spool essentially coaxial with each other.
  • the carrier is preferably between the operating position and the Decommissioned position pivotable about a pivot axis.
  • the pivot axis of the carrier is particularly advantageous when the Valve spool substantially coaxial with that arranged on the valve spool Axis. This ensures that the valves when pivoting the carrier not be operated unintentionally.
  • the carrier is expediently in its operating position lockable.
  • the battery compartment is secure when the truck is operating locked.
  • the operating device shown in FIG. 1 is one in the area of a driver's seat 1 Truck arranged.
  • the driver's seat 1 is located on the hood 2 Battery compartment in which a battery block 3 is arranged.
  • an operating lever 4 shown in its operating position.
  • an operating lever rod 5 is also part of the Operating lever 4 .
  • the operating lever extension 6 is on a valve slide 7 of a valve 8 rotatably mounted about a first axis 9.
  • the actuating lever extension 6 rotatable about a second axis 10 and in one defined direction slidably.
  • Valve slide 7 arranged axis is on a support, not shown (see Figure 2 and 3, position 13) elastically mounted on both sides, together with a Attachment part 11 and the actuating lever 4 of the solid line shown operating position in a shown with dashed lines Out of service position can be moved.
  • the carrier is in its operating position lockable, so that the attachment part 11 in the operating position, the hood 2 safely closes. Falling out of the battery pack 3 is thus also in accident situations safely prevented.
  • FIG. 2 shows an operating device according to the invention with four actuating levers 4a-d in top view.
  • Each of the operating levers 4a-d has an operating lever extension 6a-d, which are mounted about the second axis 10 with elongated holes.
  • Race Actuating lever 4a-d is associated with a valve slide 7a-d and a valve with the actuating lever extensions 6a-d around the independent first ones Axes 9a-d rotatably supported.
  • the first axes 9a-d are in the neutral position of the actuating levers 4a-d to one another coaxial and also coaxial to an axis 12 about which the carrier 13 relative to one Frame 14 of the truck can be pivoted. Using a locking pin 15, the carrier 13 can be locked in the operating position shown.
  • the axis 10 is mounted on the carrier 13 with damping elements 17. When panning of the carrier 13, the operating levers 4a-d are also pivoted without one Adjust the valve slide 7a-d to effect.
  • FIG. 3 shows the arrangement of FIG. 2 in front view. You can see here in particular the valve block 16 to which the four valves in this exemplary embodiment are summarized.
