DESCRIPTION:
BRIEF SUMMARY
BACKGROUND
The invention relates to an arrangement for control means in rock drilling equipment, comprising at least one control member for controlling operating means of a rock drill; an electronic control unit connected to the control member for controlling the operating means on the basis of a control signal from the control member; a set-value adjuster for setting the operations of the control unit; and means for setting the operating parameters of each operating means.
Various control means are used today for controlling and adjusting the different rock drilling operations. In such control means, various control parameters are also set for the different operations. These control parameters determine the feed, percussion and operating values of a rock drill in the different operational situations, such as collaring and normal drilling in the rock drilling process.
As is well-known, the operations and operating parameters of the different operating means are set in present-day control means by adjusters provided in each adjustment unit or in a separate control unit for the control means, i.e. electronically by using adjusting resistors each one of which is adjusted mechanically until a desired operating value and set value is achieved. In practice, the preliminary adjustment is performed at the factory stage either according to preset values or by performing drilling experiments and testing the operation of the drilling equipment and then making the adjustment accordingly.
In the normal use of the equipment, the driller typically needs different modes of operation and operating values than those preset at the factory. Adjusting resistors are thus adjusted in different ways, which in some cases results in poor and inefficient operation. As these adjusters do not have any clear fixed initial position, the re-adjustment of the equipment to the original set values is laborious and complicated and causes costs and wastes work time. In addition, poorly adjusted equipment is less productive and thus expensive in use.
SUMMARY OF THE INVENTION
The object of the present invention is to provide an arrangement which allows drilling values to be initially set easily and simply and which also allows the drilling values to be adjusted if required while the initial set values can nevertheless be restored simply and easily.
The arrangement according to the invention is characterized in that the setting means comprise an electronic basic set-value memory in which the set values of the operating parameters of the different operating means are programmed permanently and from which the control unit is able to read them; a separate electronic operator set-value memory in which the operator can store desired set values for the operating parameters of the different operating means by means of the set-value adjuster and from which the control unit is able to read the operating parameter values so set by the operator for each operating means, whereby the operator is able to select the operating parameter values of either one of the memories for the control of the operating means.
An essential aspect of the invention is that the control means have a separate basic set-value memory, in which the basic set values of the different operating parameters that have previously proved appropriate are programmed at the factory stage. Another essential aspect of the invention is that the control means comprise a separate operator set-value memory, into which the driller can feed desired set values from a controller, such as a keyboard, so as to achieve the desired operating parameters. Still another essential aspect of the invention is that the operating parameters can be restored to the original values set at the factory by reintroducing the parameter set values stored in the basic set-value memory. According to another embodiment of the invention, the arrangement further comprises a separate diagnosing unit capable of monitoring the functioning of set parameters so as to find out if the settings are appropriate. This allows any illogi
