Definitions

  • the invention relates to an actuating device for at least one hydraulic Valve of an industrial truck, the valve being moved by moving a
  • the valve spool can be operated and the valve spool with an operating lever connected is.
  • Hydraulic slide valves for example to control the various Functions of a load suspension device are usually in the industrial trucks Area of a driver's cab arranged, wherein a movement of the operating lever mechanically transferred to the valve spool.
  • Actuators of the for this purpose the prior art has a complex mechanical linkage with which a pivoting movement of the actuating lever in a longitudinal movement of the Valve spool is transmitted.
  • the present invention has for its object to provide a simple, Easy to install actuator that is ergonomic can be operated advantageously.
  • This object is achieved in that the operating lever a first axis is rotatably supported and the actuating lever about a second axis rotatably and slidably mounted in a direction perpendicular to the second axis where the first and second axes are parallel to each other and one of the two Axes on the valve spool is arranged.
  • 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.
  • 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 location the actuating lever is thus precisely defined in relation to the valve.
  • Valves are provided with a valve spool, each valve spool with one operating lever is connected.
  • 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 ones Prior art arrangements can be significantly reduced.
  • Each actuating 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.
  • At least one Actuating lever movable from an operating position to a non-operating position.
  • the operating levers remove theirs while the industrial truck is operating Operating position, with which the positions of the operating lever in neutral position and are included when the valve is actuated. With the inoperative position Actuation lever is not intended to actuate the valve.
  • the one that is not arranged on the valve slide is Axis at a between an operating position and a non-operating position arranged movable relative to the truck.
  • the operating position or out of service position of the carrier corresponds to the corresponding position of the Operating lever.
  • 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.
  • An ergonomic arrangement results when the operating lever in Operating position at least partially above a hood of a battery compartment of the Truck is arranged.
  • a driver's seat is usually on the hood of the battery compartment.
  • the carrier is or a component rigidly connected to the carrier when in the operating position
  • Carrier arranged so that opening of the hood is prevented.
  • the hood is thus automatically when the operating levers are in the operating position locked.
  • 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 is shown in its operating position.
  • Also part of the Operating lever 4 are an operating lever rod 5 and a kinked Operating lever extension 6.
  • 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.
  • 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 spool 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 the actuating levers 4a-d in the neutral position to each other 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.
