Definitions
- An area of use for control devices of the kind here intended is in combination with and simultaneous control of a number of electrohydraulic set devices in which the position of a hydraulically moved set piston is accurately controlled by means of an electromagnetically actuated control slide for the hydraulic liquid acting upon the set piston.
- the coils of the electromagnets of the set devices are then the current consumers, the operating current of which shall be controlled.
- a control device of the kind here inteded is used for controlling the hydraulic valves which are used to control the supply of hydraulic liquid to the drive motors for the different movements of a hydraulically operated implement.
- implements are cranes, different types of gripping arms and the like.
- a control handle with a one hand gripping portion carries a circular disc at its lower end which is centrally journalled to admit a universal movement of the disc and the handle.
- the disc covers a housing for a number of current varying devices , usually conventional po tentiometers , with a respective movable set device .
- the movable se t devices are so arranged in the housing and coupled to the disc that tilting of the normally upright handle in a certain direction determines which one of the set devices of the current varying devices , that shall be operated .
- the tilting ampli tude is decisive for the magnitude of the through current .
- a first object of the invention has been to provide a control device of the kind here intended , at which the disadvantage stated above have been eliminated .
- this has been attained in that the swingable lever is articulated wi th a further pivo t axis , wi th which the other rotational shaft coincides , the corresponding current varying device of which and associated set member are arranged in the swingable lever in direct connection with said other rotational shaf t .
- a further object of the invention has been to eliminate such disadvantages at a control device of the last-mentioned kind.
- control handle carries a bearing for a rotary shaft of the further set member, said shaft being arranged and designed with a finger grip portion, so that it is available for rotation by finger operation from the same hand, when the handle is gripped for operation of said one set member.
- the control arrangements according to Figures 1 and 2 have a handle 2 with a recessed support surface 4 for the thumb. At its upper end the handle 2 carries a housing 6, in which a shaft 8 is rotatably journalled. The function and joumalling of the shaft 8 will be described more closely below.
- One end of the shaft 8 carries a finger operating means 10 intended for rotation of the shaft and having. a shape that generally appears from Figures 1 and 2. More particularly the finger operating means 10 has a thumb supporting tongue 12 and a fore-finger supporting tongue 14.
- the rotational movement of the finger operating means 10 and shaft 8 is restricted by two pins 16 extending from the housing 6, between which a further tongue 18 of the means 10 extends in a direction from the shaft 8.
- the member 10 is kept spring biased in a well defined middle position, where the tongue 18 is located in between the pins 16.
- the arm 24 carries a housing 26, in which a further shaft 28 is journalled, that extends perpendicularly to the shaft 22.
- the shaft 28 at one of its ends is rigidly connected to a frame portion 30 and also the function and journalling of this shaft will be described more closely below.
- the frame portion 30 thus by means of the shaft 28 carries the unit consisting of the members 2 - 26. Also movements about shafts 22 and 28 are restricted and spring biased in both directions so that the parts 2 and 24 take the rest position illustrated in Figures 1 and 2 in relation to each other and the frame portion 30.
- the arrangement is principally the same for both shafts and is shown in Figures 1 and 2 for the shaft 28.
- the frame por tion 30 in its wall facing the housing 26 has an arcuate slot 31.
- a pin 32 engages that is fixedly connected to the housing 26 and located straightly below the shaft 28.
- a piston 34 guided in a bore 33 abuts from each side, said piston being spring biased by means of a screw spring 35 against the pin end 32.
- the spring force of the springs 35 is controllable by means of each a screw 36 arranged axially with the spring 35 and piston 34. In Figure 2 only one of the arrangements 34, 35 is more closely visible.
- the rotational shafts 8, 22 and 28 each carry a control element of ferromagnetic material included in a magnetorresistor potentiometer of conventional kind.
- Amplification circuits which can be of a kind essentially conventional in connection with magneto resistor potentiometers, are arranged in the frame portion 30 and connected to the respective magneto resistor potentiometers. Parts of the connections extending between the frame portion 30 and the housing 26 and between the housing 26 and the housing 20 are shown at 46 and 48, respectively.
- Connectors for outer connection to the magneto resistor potentiometers are indicated at 50 on the underside of the frame member 30.
- Magneto resistor potentiometer devices corresponding to the above mentioned appear in Figure 2 for the shaft 22 and in Figure 1 for the shaft 28.
- the shafts are thus rotatably journalle in the respective houses by means of a ball bearing 58 at each end.
- the shafts in the same way as the shaft 8 carry a control element 54 of ferromagnetic material.
- the magneto resistor plates are indicated.
- the control devices shown in Figures 1 and 2 can be con nected to each six electrohydraulic set devices of the kind de scribed by way of introduction and for the purpose likewise de scribed in that connection.
- Each magneto resistor potentiometer controls the magnetizing currents of a pair of such electrohydrau ⁇ c set devices.
- Each of the control devices shown in Figures 1 and 2 can consequently be used to control the current supply to the coils of the six electrohydraulic set devices, required to control a hydraulic valve with three valve slides, of which the moving direction determines the moving direction of a corresponding movement function obtained by means of a hydraulic motor and the magnitude of the stroke determines the velocity of the movement. More particularly two electrohydraulic set devices cooperate in pairs from each its end of the valve slide to operate the same and the current supply to the coils of each such pair is controlled by rotating a corresponding one of the shafts 8, 20 or 28. Rota tion in one direction then supplies current to one of the coils, whereas the other one is left without current, and vice versa.
- a closer description of the function of the set device and its cooperation with a hydraulic valve is given in a copending PCT application No. (ref 24766).
- the finger tip operation of the operating member 10 is carried through with small movements and requires little power from the muscles of the hand.
- Operation about the shaft 22 can be carried through with an almost straight wrist while using a favourable lever ratio of the hooked arm, and operation about the shaft 28 essentially implies a pure pushing or pulling movement that neither requires any bending or turning of the wrist and that likewise uses a favourable lever ratio of the hooked arm.
- the invention is, of course, not restricted to the embodiments shown on the drawings and described above but can be modified within the scope of the following claims. Thus it is conceivable to design the arrangement so that the movements of the three rotational axes is used for operating usual rotary potentiometers in the place of magneto resistor potentiometers.
- control arrangement is not restricted to that given as an example above. Genera y the arrangement can e use anyw ere it is desirable to simultaneously control the fluid supply to a number of consumers with mutually different and varying needs. In the place of potentiometers thus also hydraulic valves could be controlled.
- the position of the rotary shafts with respect to each other can, of course, also be varied and it would e.g. be con ceivable to have longer or shorter distances between the two perpendicular shafts 22 and 28. Generally it can be stated that a longer distance implies more favourable working conditions as regards the movement of the arm, especially, the wrist.
