Title: CABLE LAYING DEVICE AND METHOD
Abstract:
The invention relates to a novel mobile device (100) for the underground laying of at least one flexible line, a cable, a cable-pulling empty pipe or fluid transport tube, in particular below the traffic routes or roads laterally next to verges or strips of road. The device is characterised in that, in particular for laying cables along a curved traffic route - the front vehicle (1) embodied as a support vehicle comprises a rear support frame (20), a lateral ejection unit (2), a milling unit (3) with a milling wheel (31) and a drag formwork or cable laying unit (4) following said wheel, a mobile mechanical compact unit (10), which can follow bends, in which the milling unit (3) and with which the milling wheel (35) is connected to the front vehicle (1) such that it can pivot laterally at an angle of up to ± 25°, in particular up to ± 20°, laterally offset towards the outside with respect to the front vehicle (1), and can be positioned to laterally protrude over the contour of the front vehicle (1), by means of a primary articulation or a swivel joint (230) on the lateral ejection unit (2) having an axis of rotation essentially vertical with respect thereto on both sides. The drag formwork, cable laying and cable introducing unit (4) follows the milling unit (3) and the cable introducing unit (4) is connected to the milling unit (3) also by means of a second articulation or a second swivel joint (340) such that it can pivot laterally at an angle of ± 25°, in particular up to ± 20°.
