Definitions

  • the invention relates to a device for wireless Control of single or multi-axis proportional working Conveying and lifting technology machines in the form of a Remote control.
  • a major disadvantage of these Hall sensors is their high level Price. Another disadvantage is that when using control devices, in which these sensors are built, the operation of the machine in the event of a failure of the Operator is not reliably prevented.
  • the present invention is therefore based on the object of providing a device for wireless control, which is a so-called Dead man protection ", and with which exact proportional control signals can be sent out at the same time, whereby an operator should be given a simple possibility of recognizing the switching position of the device.
  • Pushbutton actuator ensures that one with the device wirelessly controlled machine in the event of operator failure switches off reliably.
  • the first stage serves thereby activating the button actuator or a first one Select function.
  • the second stage is proportional Control of the machine to be controlled in at least an axis.
  • the elastic proportional actuator which is rectangular to the snap switch element on the button actuator is arranged, as well as by the proportional actuator Arranged sensors can be an exact proportional Movement of the machine to be controlled can be achieved.
  • the sensors on the board as Force sensors are designed with pressure transducers on Change of the contact area and / or the contact pressure react.
  • the sensors can advantageously be used as inductive, capacitive, oleohydraulic, piezoelectric or resistance changing Sensors be formed.
  • This type of sensor ensures a safe absorption of pressure or take away and a corresponding possibility of Further processing of these pressure forces or paths guaranteed.
  • a membrane seal is arranged between the transmitter housing and the Push button actuator.
  • the recess as a square recess is formed in which four sensors are arranged in this way are that there are two sensors facing each other.
  • the recess is designed as a square recess particularly simple manufacture is possible.
  • four sensors can be optimal control in two Get directions.
  • the proportional actuator on its the sensors facing side is resilient, can be a particularly advantageous change in circulation between the proportional actuator and the sensors. With With the help of this change in conditions, a signal can be passed on become.
  • the guide element in the Push button actuator is designed as a guide ball is.
  • the guide element As a guide ball optimal movement of the push button actuator achieve.
  • the guide ball is constructive easy and cheap to manufacture.
  • the wireless control device consists of a Transmitter housing 1, not shown, with a cover, by means of a membrane seal 2 with a push button actuator 3 is connected. Fastening the membrane seal 2 on the transmitter housing 1 takes place through a membrane ring 4. This membrane ring 4 is followed by a lock nut 5 pulled down. As a result, the membrane seal 2 between the membrane ring 4 and the transmitter housing 1 clamped. On this way a high degree of tightness, in particular Watertightness and moisture tightness achieved. The Membrane seal also centers the button actuator 3.
  • the button actuator 3 is in one at its lower end Guide ball 6 movably supported as a guide element.
  • a snap-action switching element is located under the guide ball 6 7.
  • buttons actuator 3 must be as long be pressed until after a linear movement of the guide ball 6 the snap-action switching element 7 with the printed circuit board 13 contacted.
  • This position of the button actuator 3 is the first Switch stage represents and becomes the operator through the training of the snap switching element 7 reported tactile. It there is now a current flow, so that the control of a Machine is enabled. The button actuator 3 must therefore always be pressed down before another Control can take place, and returns immediately when released back to its original position.
  • Dead man protection designated protection is advantageous in the event that an operator fails, especially in the case of cranes or similar equipment with heavy suspended loads, since the failure of an operator can represent a great danger in such machines.
  • the first switching stage thus has a switch-on / switch-off function and is also available with a pre-selection or Select function can be assigned if, for example, only one movement is desired at a certain level.
  • proportional actuator 8 on the pushbutton actuator 3 arranged, the direction of actuation at right angles to the Actuating direction of the snap switching element 7 runs.
  • sensors 9 on the walls a square recess 10 is arranged.
  • the proportional actuator 8 tapers in the upper area towards a head 18 of the button actuator 3, so that between the proportional actuator 8 and the sensors 9 an increasing open space is created.
  • the button actuator 3 can thus a larger area of Proportional actuator 8 used as a contact surface for measurement become.
  • the one in the lower area of the proportional actuator 8 arranged open space due to the curvature of the proportional actuator 8 is essentially provided to displace the elastic material.
  • the sensors 9 are in the present Exemplary embodiment as force sensors with pressure sensors trained and respond to surface pressure by their change electrical resistance. By not shown Facilities will change this resistance in known way converted into a 5 bit resolution and forwarded via a radio signal.
  • the guide ball 6 is in a two-part ring guide stored and managed.
  • This ring guide consists of a upper ring 11 and a lower ring 12.
  • the upper ring 11 has a slightly smaller diameter than the guide ball 6 on. In this way, pulling out the Pushbutton actuator 3 prevented.
  • connection circuit board 14 To transmit the signal from the sensors to one below of the snap-action element 7 attached circuit board 13 serves a connecting circuit board 14.
  • the connection of the Connection circuit board 14 is carried out with the circuit board 13 via pins 15. These pins 15 are each bipolar and enable optimal transmission of the signal.
  • the sensors 9 are fastened on a sensor support 16.
  • a cover part 17 which on Transmitter housing cover 1 is present. Obtained through the cover part 17 the underlying parts have a corresponding guide.
  • the cover part 17 also represents a conclusion.
