Definitions
- the invention relates to a hoist winch, in particular one Kelly winch for civil engineering drills, according to the generic term of claim 1.
- a hoist winch comprises a rotatable mounted drum for receiving a rope, a drive, through which the drum for winding and unwinding the Rope is rotatable, a measuring device for measuring a Rope load and a control unit for the drive, being by the control unit based on the measured rope load a tensile force on the rope can be determined and with a specifiable Residual traction is comparable.
- a generic hoist winch or cable winch comes from the DE 297 23 821.
- This winch can be used universally and allows one for a variety of applications efficient operation.
- a control unit provided, which in connection with a measuring device measures a pulling force and ensures that a residual pulling force is retained on the rope. Because should be the burden would stand up on the rope with the drum rotating the rope is no longer under tension and it would then form a larger amount of slack rope. This is not More tensioned rope can cause the rope turns no longer, as intended, in the grooves of the rope drum lie, but grooves are skipped, or the turns come to lie on top of one another in an uncontrolled manner. Such an unclean winding on the winch leads to high Rope wear.
- the winch as a Kelly winch for the rotary drilling process problems arise here.
- Hit the load so for example a Kelly bar
- a firmer medium for example water in a borehole
- the tensile force on the rope can fall below the residual tensile force. This then leads to the drive being switched off Winds.
- the winch drive starts again and winds it Rope down at the original speed. by virtue of the lower rate of descent of the load, for example in the water of the borehole, but continues to arise Slack rope so that the winch is stopped again. This can form an oscillation limit cycle, which a quick and efficient lowering of the load is impaired.
- the object of the invention is to improve a generic hoist winch and to provide a method for operating a hoist winch which enables efficient winch operation in a particularly wide range of applications.
- the hoist winch according to the invention is characterized in that that the control unit and the measuring device for continuous Determination of the current tensile force on the rope are trained and that when the tensile force falls below the power of the drive under the residual traction Control unit can be reduced and adapted, whereby by a regulation kept the traction above the residual traction becomes.
- the drive does not stop, but only on reduced a small value. This reduces the rate of descent of the load, the rope tension increased and again above the threshold of the residual tractive force can rise. Then preferably again increase the power of the drive, so that an almost optimal rate of descent can be adjusted can. So it’s going to be a simple black and white scheme, the winch drive when falling below the residual winch pulling force completely switched off, avoided. The danger of emergence an adverse vibration limit cycle with a Constant switching on and off of the winch drive is largely reduced and practically excluded.
- a preferred embodiment of the hoist winch according to the invention is that the drive as a hydraulic Drive is formed.
- a hydraulic drive is relatively stiff, i.e. he can with very little delay changes in performance and thus changes in the speed of the rope accordingly the specifications of the control unit. This is for one quick adjustment close to the optimal working point and the optimal sinking speed is particularly advantageous.
- control unit together with the hydraulic drive an electro-hydraulic Regulation forms.
- the control unit can electric valve or a very small electric one Control servomotor, which in turn controls the hydraulic drive, as part of a hydraulic torque boost is controlled.
- the measuring device on a deflection roller or arranged in the region of the drum is.
- a measurement of the rope load in the area of the drum can about a torque support, for example in connection with the generic class the technology is described and known.
- the control unit preferably has a data memory to save at least essential data of the previous one Stroke cycle, such as stroke length and reversal points, and a processor to evaluate and influence the next stroke cycle based on the data.
- the invention is characterized in that that the control unit falls short the current pulling force below the residual pulling power the drive diminishes and adjusts and the performance of the drive based on the currently determined tractive force is regulated by the control unit.
- a particularly efficient operation in terms of lowering speed is achieved according to the invention that the rope load is continuously by the measuring device is measured and that the control unit continuously the instantaneous tensile force of the rope determined and with the predetermined Compares residual traction.
- the procedure is to stop the rope at a lower reversal point at each stroke cycle is stored in the control unit and that with the following stroke cycle before reaching the previously saved one Low reversal point is the power of the drive is reduced by the control unit. This is particularly so advantageous when drilling with Kelly rods, to a faster and more gentle stopping of the To reach rope load.
- First, every stroke cycle by measuring and evaluating the rope unwinding path through a suitable length measuring device the respective reversal point stored on which a downward movement in an upward movement or vice versa. This turning point according to the uncoiled length in one corresponding memory unit noted in the control unit. Because with Kelly drilling in the subsequent drilling cycle the following kelly bar essentially the same or a defined changed height must, according to a predetermined program in the Control unit a gentle and fast braking movement the rope speed before the turning point become.
- the invention achieved an "intelligent" lifting winch, so to speak, at which the control unit taking into account the current and the previous operational sequence Adjust the almost optimal lowering speed of the rope can.
- FIG. 1 and 2 is a winch according to the invention 10 illustrates.
- a drum 12 is on drum bearings 14a, 14b rotatable about a central axis 18 on a frame 13 mounted with two frame supports 13a, 13b.
- the drum 12 is designed to receive a rope 11, which one or can be wound up in multiple layers on the drum 12.
- a drive 16 is provided for rotating the drum 12 and thus for opening or closing Unwinding the rope 11.
- This can be an engine or a combination of an engine and a gearbox.
- the drum 12 is designed as a hollow drum, in the hollow or interior of the drive 16 with its drive shaft 17 is arranged coaxially to the central axis 18.
- the torque transmission between the drive 16 and the Drum 12 takes place via a rotary connection, which is a Keyway connection can be.
- a measuring device On the torque support mounted with two connecting bolts 20 a measuring device, not shown, is provided, through which the supported torque can be determined is.
- the measured value determined in each case can, for example via a line 21 to a computer unit, not shown be forwarded in which according to the Drum diameter taking into account the number of Rope layers on the drum 12, which the actual Can expand drum diameter, one on the rope 11 Force is measured.
- the measured Traction value is controlled by the drive 16, wherein if the tensile force value is reduced, the Power of the drive 16 and thus the unwinding speed he follows.
