Embodiment Construction

[0043] figure 1 Shown is an excavator 2 a which, as an earth-moving machine, has a position determination system according to the invention. The excavator 2a travels on the ground surface 10 to be excavated. For example, excavation work is part of building roads or laying wires or pipelines. Below the ground surface to be excavated there is already laid a supply line 1 as an underground object, where the supply line 1 emits an electromagnetic field. The excavator 2 a has an excavator arm 3 a , which as working parts has a first arm part 11 a and a second arm part 12 a as well as a bucket 13 a , each of which can be adjusted in height by means of hydraulic cylinders. On the second arm part 12a are arranged a fixing part 4a, a flexible connection part 7a and a detection part 5a as parts of the position determination system according to the invention, where the fixing part 4a is configured to be fixed magnetically on the second arm part The upper housing and is used for the in...

Abstract

The invention relates to a localization system for localizing an underground object (1) for an earthmoving machine (2a) comprising a working part (3a). Said localization system comprises a fastening component (4a) and a detector component (5a). The fastening component (4a) can be arranged on the working part (3a) for example by means of magnets. The detector component (5a) is adapted to detect theobject (1) using an electromagnetic field that can be associated with the object (1) and is arranged on the fastening component (4a) so as to swing like a pendulum, thereby effecting an alignment ofthe detector component (5a) under the effect of gravity. Optionally, the localization system comprises an arithmetic component for deriving a distance information of the object (1) from the detected value. The localization system also comprises a display component for displaying and / or forwarding the detected value and / or the distance information.

Description

technical field [0001] The invention relates to a position determination system for an earth-moving machine for determining the position of underground objects according to the preamble of claim 1 . Background technique [0002] During earthworks, especially when excavating, it is necessary to know the buried position of underground objects, such as underground supply lines, in order to avoid, for example, damage to the supply lines and / or the earthmoving machinery used. Often records about these objects are incomplete, erroneous, or even non-existent. Therefore, a survey of subsurface objects must be carried out on the land to be excavated before earthworks can begin. Such investigations are usually based on the detection of electromagnetic fields that can be assigned to the object, for example using a common hand-held position finder. [0003] Scanning land is time-intensive and cost-intensive, especially when working on large areas. Therefore, position determination de...
