Problems solved by technology

However, it cannot normally be considered that the machine is not moved laterally by these track drives
Such movement implies lateral movement for the construction tools mounted on the machine, which in turn results in imprecise construction of the structure to be constructed
Merely measuring the steering angle of the track drive, such lateral drift cannot be detected

Embodiment Construction

[0024] exist figure 1 In FIG. 1 , various positions of the prior art mobile construction machine 1 when turning along the predetermined projection line 7a of the structure to be constructed are shown for the purpose of illustration. When driving around a bend, the longitudinal machine axis 13 should be parallel to the tangent 6 of the projection line 7 a at the point of contact of the tool 5 and the projection line 7 a in every position. In order to avoid lateral movement of the tool, when steering the machine's front track drives 2 and 3, it is necessary to steer the rear track drive 4 in the opposite direction.

[0025] figure 2 A lateral drift correction device according to the invention is shown with a sensor part 8 and an analysis part 9 mounted under the bottom of the slipform machine 1a adjacent to the construction tool 5a. The sensor part 8 determines the ground condition of the ground part 11 passed by the construction machine and sends this information to the anal...

Abstract

The invention relates to a sideways drift correction device for a mobile production machine comprising a removal of material and a tool for processing the removed material, having a sensor component and an evaluation component. The sensor component detects the structure of at least one part of the underground surface relative to which the production machine moves. The evaluation component determines the relative motion direction of a reference point on the production machine relative to the subsoil from the time-variable information of the underground surface, and derives steering correction information therefrom.

Description

technical field [0001] The invention relates to a lateral drift correction device according to the preamble of claim 1 for a mobile construction machine having a material application section and a tool for handling the applied material. Background technique [0002] Mobile machines for laying curbs or sidewalks have long been known. Such paving construction is usually carried out in three stages: application of the material such as concrete, rough troweling of the material and fine troweling of the material. All three stages are carried out while the machine is traveling, for example by means of a corresponding slipform tool. The machine travels at a speed of about 20 meters per minute during construction work. Here, any deviation from the heading of the mobile machine specified for construction may lead to errors in the structure to be constructed by the tool. Therefore, first of all for machines with sliding formwork (eg Curb & Gutter Maschine), lateral drifting when dr...
