Definitions
- the invention relates to a measuring arrangement with at least one measuring cable, which is connected on the one hand to the vertically adjustable working device and on the other hand extends to an upper fixed point, at least one measuring device, which is connected to an associated measuring cable and for measuring an angle of inclination of the measuring cable relative to a vertical measuring axis and is arranged in a connecting area between the measuring cable and the working device, and at least one connecting device, which is arranged between the measuring device and the working device and is designed such that the measuring device is non-rotatable about the vertical measuring axis and at the same time can be angled to the vertical measuring axis on the To hold implement, according to the preamble of claim 1.
- the invention also relates to an excavation device for creating a hole, in particular a slot, in the ground, with a working device which has at least one excavation tool for excavating soil, a carrier device on which the excavation device is mounted in a vertically adjustable manner for introduction into the ground, and a measuring arrangement for measuring the position, in particular a verticality, of the implement in the ground, according to the preamble of claim 10.
- a slot in the ground When creating a slot in the ground, deviations from a desired vertical alignment or position of the slot can occur due to various influencing factors.
- An exact position-accurate creation of a slot in the ground is of essential importance, for example when creating a diaphragm wall, as is required, for example, to seal deep excavation pits against in-situ groundwater.
- Such a slot wall is made from a large number of individual slots which are filled with a settable compound. It is necessary to create the individual diaphragm wall segments exactly next to each other so that there are no gaps and thus leaks between the diaphragm wall segments.
- a very precise method for measuring a borehole in the ground using at least one measuring cable, which extends from a measuring body to a carrier, is known from EP 2 698499 B1.
- a device-independent measuring device is required, with which an angle and distance measurement has to take place.
- a change in the position of the measuring cables can serve as a measure of the alignment and in particular the verticality of the hole in the ground.
- this measuring arrangement cannot be used directly to control a removal device.
- EP 0 841 465 B1 A measuring arrangement of this type can be found in EP 0 841 465 B1.
- two spaced-apart measuring cables are stretched from predetermined fixed points on a ground surface to a trench wall cutter. With an exact vertical lowering of the trench cutter, the measuring cables are aligned vertically. If the trench wall cutters deviate from the vertical, an angle of inclination is set on the measuring cable. The measuring angle can be determined using an inclinometer at the connection area between the measuring cables and the working device. In order to determine even small deviations as precisely as possible, the measuring cables should be attached to the working device so that they can be adjusted as freely as possible.
- EP 0 841 465 B1 teaches the attachment of a ball joint or a card joint with pivot axes crossing one another.
- EP 3 536 899 A1 a special gimbal mounting is taught for this measuring arrangement, with which a particularly good measuring accuracy is to be achieved.
- the cardanic mounting has a large number of mechanical parts, which, however, when used on construction sites and in particular when introducing the working device with such a measuring device in parts filled with concrete suspension Slots require a high level of cleaning and maintenance. Inadequate cleaning and maintenance of the sensitive mechanical cardanic linkage can result in undesirable measurement inaccuracies.
- the invention is based on the object of specifying a measuring arrangement and a removal device with such a measuring arrangement, with which a particularly reliable and precise measurement is made possible with a robust structure.
- connection device has a connecting tube which is arranged coaxially to the vertical measuring axis, and that the connecting tube is designed to be torsionally rigid about the vertical measuring axis and deflectable to the vertical measuring axis.
- a basic idea of the invention is to provide a connecting tube for connecting the measuring device to the working device, which on the one hand is torsionally rigid about the tube axis, which coincides with the measuring axis, and on the other hand can be deflected or bent to the tube axis.
- the use of such a connecting tube offers advantages in several respects. Unlike a cardan joint with crossing pivot axes, the connecting tube has the same deflection behavior over its entire circumference.
- a connecting tube as a joint element is simple and at the same time robust due to the fundamentally one-piece construction.
- the measuring arrangement according to the invention is therefore particularly suitable for rough work on construction sites or in other outdoor areas.
- the connecting tube can be made of any suitable material that is sufficiently torsionally rigid about the tube axis and allows a desired deflectability transversely to the tube axis.
- the connecting tube is formed like a hose from a flexible material.
- a plastic material in particular an elastic plastic material, is suitable for forming the connecting tube.
- the connecting tube is designed at least in sections as a corrugated tube with a corrugated wall area.
- the connecting pipe thus has at least one area with changing diameters, in particular increasing and decreasing diameters.
- the tube as a whole can be formed as a corrugated tube.
- the corrugated pipe is made of a metallic material, e.g. B. steel or stainless steel
- an increase in the axial rigidity of the connecting tube with a simultaneous further sensitive ability to bend the tube can be achieved in that the connecting tube is filled with an incompressible liquid. Oil or water can preferably be provided as the liquid.
- a further preferred embodiment of the invention is that at the end of the connecting tube directed toward the implement, a rotary bearing is provided with which the connecting tube can be rotated about the vertical measuring axis, in particular through an angle of 180°.
- the pivot bearing can be arranged at any point of the connecting pipe. Due to the fact that the connecting tube can be rotated around the measuring or tube axis, measuring accuracy can be increased even further.
- this can be achieved by arranging a rotary drive for turning the rotatably mounted connecting tube into at least one different position and by constructing the measuring device for measuring the angle of inclination in the different rotary positions.
- the connecting tube can be adjusted with the rotary drive into a second position, which is offset by 90° or by 180° to the first position. Another measurement can be taken in this second position.
- Flier notebook a so-called reversal measurement is possible, with which Measurement errors can be compensated or reduced to a minimum.
- a measurement can also be carried out in more than two different rotational positions of the connecting tube.
- the measuring arrangement can already be used with a measuring cable for specific purposes.
- at least two measuring cables are provided, which are attached to the working device at a horizontal distance from one another.
- the at least two measuring cables preferably run parallel to one another in a normal position.
- Three or more measuring cables can also be provided, which extend between the working device and a respective fixed point.
- the measuring cables must be in a tensioned state, whereby a tensioning device must be provided for this purpose. If only one measuring cable is arranged, twisting can be detected by a suitable detection device, for example with a gyroscope.
- a particularly good axial attachment of the measuring cable to the working device via the connecting device can be achieved by arranging a tension element inside the connecting tube.
- the pull element can be a pull cable, which also enables a sufficient deflection of the connecting tube transversely to the vertical measuring axis.
- the invention further includes an excavation device for creating a hole, in particular a slit in the ground, with an implement that has at least one excavation tool for excavating soil, a carrier device on which the implement is mounted so that it can be adjusted vertically for insertion into the soil, wherein a measuring arrangement according to the invention for measuring the position, in particular the verticality, of the implement is arranged in the ground.
- the working device can be a device for special civil engineering and in particular can include a trench wall cutter, a trench wall grab or also a down-the-hole drilling device or a drilling tool.
- the carrier device is in particular a construction machine with a mobile undercarriage on which a rotatable superstructure is mounted.
- the subcar may in particular comprise a crawler chassis.
- a particularly preferred embodiment of the removal device according to the invention is that the measuring cable has a density which is the same as or less than the density of a supporting liquid with which the hole created by the working device is filled.
- the density is the same as that of a supporting liquid on its surface in the hole, undesirable effects on the cable due to density differences can be avoided. This increases the reproducibility of the measurement result.
- the density of the suspension can be constant or change depending on the depth.
- a measurement can be carried out continuously or at predetermined times by the measuring arrangement. Depending on the measured values determined, a deviation in the position of the tool in the hole can be detected at an early stage. In principle, the implement can then be readjusted manually.
- the working device is provided with controllable actuators for changing the position of the working device in the hole and that a control and evaluation unit is provided and configured on the control device, depending on the measured values of the at least one measuring device, a position of the implement and to change it by controlling the actuators.
- a control and evaluation unit is provided and configured on the control device, depending on the measured values of the at least one measuring device, a position of the implement and to change it by controlling the actuators.
- a particularly advantageous removal device is achieved according to a further development of the invention in that a winch is provided for each measuring cable on the carrier device, through which the measuring cable can be tracked to the working device under a predeterminable pretension.
- the pre-tensioning can in particular be set in such a way that the measuring cable is always fully tensioned, but a sensitive deflection of the measuring cable and thus a high measuring accuracy are still provided. This can be achieved by setting an appropriate tightening torque on a winch drive for the winch.
- the at least one fixed point can be provided at any suitable location that allows the measuring cable to be fixed reliably and permanently.
- a guide ditch with concrete walls along a ground surface is provided.
- a guide frame, preferably made of metal, can be arranged and fastened along this guide trench.
- Fixed points for the measuring cable can be fixed on this guide frame using appropriate holding devices.
- a measuring sleeve and/or a deflection roller can be arranged on the guide frame for this purpose, through which or over which the measuring cable is suitably guided.
- the fixed point can be calibrated in particular for a particularly precise measurement, so that, for example, there is an unambiguous definition of the position in a construction site coordinate system.
- the working tool of the removal device can be any construction tool for creating a hole in the ground.
- the working device is a trench wall cutter with at least one driven cutting wheel, which is mounted at a lower end of a cutting frame so as to be rotatable about a horizontal axis of rotation.
