Definitions
- the invention relates to a hand-operated control device which is used in particular for the hydraulic actuation of hydraulic valves and which has the features from the preamble of claim 1.
- Such a manually operated control unit is e.g. known from DE 27 51 946 C2.
- the control unit has a control lever, which is gimbal-mounted on a device housing via two shafts or stub shafts, the axes of which span an axis plane and intersect at a pivot point, and can therefore be pivoted on all sides around the pivot point from a neutral position.
- 15 signal generators are provided with four directly controlled pressure reducing valves, which are arranged at angular intervals of 90 degrees around a lever axis that is perpendicular to the axis plane and passes through the pivot point.
- Each pressure reducing valve includes a plunger, which is guided in the device housing parallel to the lever axis, protrudes from the device housing and can be pressed down by a plate-like actuator that is firmly connected to the control lever against the force of a return spring and a control spring of the respective pressure reducing valve.
- the return springs engaging the tappet ensure that the control lever assumes a neutral position if it is not actuated from the outside and is not intended to be locked in a pivoted state.
- the control lever is pivoted in a plane which is determined by the axes of two diametrically opposed pressure reducing valves, one of four pressure reducing valves that is, a control signal transmitter is actuated.
- a control signal transmitter By pivoting the control lever in a different plane, it is possible to actuate two pressure reducing valves at the same time, the degree of actuation of one pressure reducing valve in comparison to the degree of actuation of the other pressure reducing valve depending on the position of the pivoting plane.
- the control device has, in addition to four pressure-reducing valves, an electrical switch, the actuation of which energizes the electromagnets of the switching valves and switches the switching valves.
- an electrical switch the actuation of which energizes the electromagnets of the switching valves and switches the switching valves.
- a hydraulic control unit which already has a hydraulic pump and a hydraulic tank connection, must also be supplied with electrical energy.
- actuation of an electrical switch requires releasing the control lever or, if the electrical switch is integrated in the control lever, at least changing the access. A malfunction of the electrical switch can lead to dangerous situations because valves other than those desired are operated.
- the invention has for its object to develop a hand-operated control device with the features from the preamble of claim 1 so that a variety of hydraulic valves can be operated safely with it without excessive effort.
- a further control signal transmitter is then arranged between two first control signal transmitters.
- the control lever together with the actuator can be rotated about the lever axis from a first rotational position into a second rotational position and vice versa, the first control signal transmitter being acted upon by the actuator in the first rotational position.
- a recess in the actuating element lies in the first rotational position of the control lever above the further control signal transmitter, so that it cannot be actuated in the first rotational position.
- the invention can preferably be applied to a manual control device which has four first control signal transmitters around the lever axis at a respective angular distance of 90 degrees.
- the control of a further directional valve axis in two directions is then possible according to claim 4 in that diametrically opposite each other with respect to the lever axis and in each case centrally between two first control signal generators, two further control signal generators are arranged and that the actuator is provided with four recesses, which are in the second Rotation position in the area of the first control signal transmitter.
- the further control signal generators can be actuated in the first rotational position of the control lever and only the further control signal generators in the second rotational position of the control lever.
- control lever is not rotationally symmetrical with respect to the lever axis, so that based on its position it can be recognized whether it is in the first or the second rotational position.
- FIG. 1 shows the exemplary embodiment partly in view, partly in a section through the lever axis in the area of the control lever bearing
- Figure 2 shows a cross section through a bearing bush of the control lever for the
- the control device shown is a hydraulic control device which is constructed on the basis of pressure reducing valves.
- a total of eight pressure reducing valves 11 are in a mutual in a device housing 0
- the pressure reducing valves form the control signal transmitter of the control unit.
- Their internal structure is generally known and e.g. DE 27 51 946 C2 can be removed.
- tappets 13 can be seen, one of which is assigned to a pressure reducing valve and which is located in a fastening and cover flange
- a control spring of a pressure reducing valve is tensioned, or more generally a pressure reducing valve
- This actuation is initiated via the handle 20 of a control lever 21 which is attached to a universal joint 22 carried by the device housing 10 and shown only schematically.
- This has two shafts, the axes 5 of which are perpendicular to one another and intersect at a pivot point denoted by 23 and span a plane which may be referred to as the axis plane.
- the control lever 21 Due to the universal joint 22, the control lever 21 can be pivoted on all sides about the pivot point 23.
- the lever axis is perpendicular to the axis plane and also passes through the pivot point 23.
- the handle 20 is attached to a handle 24 of the control lever 21, which is bent out of the lever axis 12, so that the control lever 21 is not arranged overall rotationally symmetrical to the lever axis 12.
- the stem 24 is over one
- a plate 30 is clamped as an actuating element, which interacts with the tappets 13 of the pressure reducing valves 11 and extends in a plane running parallel to the axis plane, that is to say essentially
- I O chen is arranged perpendicular to the lever axis 12.
- the shape of this plate 30 can be seen in particular from FIG. 3.
- the plate drawn there with solid lines has the shape of a cross and is four-fold symmetrical with respect to the lever axis 12.
- the individual arms 31 of the plate 30 are thus arranged at an angular distance of 90 degrees with respect to the lever axis 12.
- a lower part 36 of the universal joint 22 is screwed into a locking bush 37 which is rotatably mounted in the device housing 10 about the axis 12 and is secured on the part 36, for example with a lock nut 38.
- a locking bush 37 In the outer surface of the locking bush 37 there are two locking recesses 39 in a plane perpendicular to the lever axis 12, which have an angular distance of 45 degrees from one another. They cooperate with a radially arranged locking pin 40, which a locking spring 41 tries to press into one of the recesses 39.
- the plate 30 In the first rotational position, the plate 30 is in the position drawn with continuous lines in FIG. It can be seen that the arms 31 extend over the tappets 13 of four first pressure reducing valves 11 arranged at an angular distance of 90 degrees from one another. If the control lever 21 is now pivoted, one or two of these first pressure reducing valves are actuated depending on the pivoting direction. The four further pressure reducing valves 11, which are also at an angular distance of 90 degrees from one another and are offset by 45 degrees from the first pressure reducing valves, remain unaffected by the pivoting of the control lever 21, since they are located in the region of the cutouts 32 of the plate 30.
- the control lever 21 is rotated 45 degrees with respect to the lever axis 12 while overcoming the latching force of the latching bolt 40 and the latching spring 41, as a result of which the plate 30 reaches the position shown in broken lines in FIG. 3.
- the arms 31 are now located above the tappets 13 of the further pressure reducing valves, while the tappets 13 of the first four pressure reducing valves lie in the cutouts 32.
- the path of the plunger 13 out of the device housing 10 is, as with those already used today and e.g. Known from DE 27 51 946 C2 control devices limited by a stop, so that the plunger 13 are held in spite of the recesses 32 in the plate 30 on the device housing 10 and the plate 30 in its neutral position, in which it is with all parts over the plunger 13 is located, can be rotated by the plunger without hindrance.
