Definitions

  • the invention relates to an off-road chassis with a central frame and with a plurality of supports adjustable in their vertical angle inclination with respect to the central frame, wherein the supports are each provided with sliding or rolling devices for support on one Floor area. Furthermore, a work device is integrated or connectable to the off-road chassis.
  • Off-road chassis of this type are known, for example, in the form of cable plows, which are used for laying a pipe or a cable into a gutter excavated by the work equipment serve.
  • a known cable plow by the applicant which is described for example in DE 196 23 922.2 is usually from a work winch positioned on a heavy truck pulled during the excavation of the gutter, being considerable on the heavy truck Powers are exercised.
  • Another genre of cable plows is self-propelled, with certain requirements, in particular, certain ground constellations of the cable plow with its own drive do not progresses more or causes very large damage in the area. It is also an accurate guide of the Cable plow may then no longer be guaranteed.
  • the object of the present invention is to provide an off-road chassis that is with comparatively low operating costs, much more precisely even over difficult ground conditions can move away in a wide variety of work assignments.
  • a core concept of the present invention is a work winch on the off-road chassis to provide for the retrieval or delivery of a train hawser to move the off-road chassis to effect or at least to support.
  • a work winch on the off-road chassis the separate winch vehicle used up to now becomes superfluous.
  • the previously used separate winch vehicle was built so heavy that special approvals for road traffic were necessary. In actual use, the vehicle was often used for soft floors too heavy, but at the same time not sufficiently heavy for the enormous tractive forces, so that it could come to tilting movements of the vehicle due to leverage. All in all conventionally, the off-road chassis and the winch vehicle were separate to one location to transport.
  • the speed of the off-road chassis can now be increased easy control by a person traveling on the off-road chassis, so that about difficult ground conditions with low speed, with light ground conditions with can be driven at high speed. Even with obstacles, such as in the laying process Crossing foreign lines, or in the slope area, the off-road chassis can be much easier be moved at the appropriate speed. In conventional, as a cable plow Trained off-road chassis relatively often caused line damage to external lines, because a reduction in speed due to the external winch vehicle is not sufficient could be done quickly.
  • the off-road chassis with the present invention can be much more gentle on the terrain and can be precisely controlled even in difficult soil conditions.
  • the new overall device is in an embodiment as a pure construction machine or agricultural machine not from an approval dependent as a truck. Even in extreme soil conditions such as swamp, bog, Forest, wet ground, stony ground, steep slopes, slope slopes, is the off-road chassis can be used with the working winch according to the invention.
  • the train cable can be attached to a suitable end Anchoring point, preferably on a support plate as known from DE-U 93 18 713, be attached.
  • the support plate in turn can preferably by means of conventional quick couplers another construction or agricultural machine that is already available on site (e.g. excavators, wheel loaders, dump trucks, etc.). Such machines are usually a lot lighter than the known winch pulling machine, so that it copes with all difficulties of the area can be.
  • the working winch is from the front end of the off-road chassis spaced and arranged on the central frame. This allows the train to Attack the off-road chassis much more centrally. At the same time, collecting or issuing the Train cabs are better controlled.
  • the train cable is also advantageous to place the working winch in the lower area of the floor surface.
  • the off-road chassis or work equipment of the off-road chassis is designed as a plow, those of the off-road chassis are due to the displacement of the earth's leverage is enormous. These leverage would go further be supported if the train cable would attack the top of the off-road chassis. On Ground-level routing will therefore usually be preferred.
  • a sufficient one Free space to the floor remains, so that the pull rope even with convex floor structures is not drawn into the ground. If necessary, however, the train cable can be used in these areas be guided over roller devices that prevent the train cable from penetrating into the ground.
  • the working winch close to the center of gravity of the off-road chassis, preferably in the normal direction of travel slightly behind the center of gravity of the off-road chassis to arrange.
  • a force attack near the center of gravity created a particularly stable constellation for the movement of the off-road chassis. If the point of attack is moved a little further back, this can be explained for reasons of a Cable guide can be advantageous.
  • a hawser guide already mentioned above is provided, through which the train hawser is carried out and a hawser-friendly and trouble-free winding and unwinding of the train cable on or guaranteed by the working winch.
  • the rope guide can be anchored.
  • the Trossen operation also actively include a lateral adjustment mechanism, depending on the winding condition the working winch brings about the desired feeding of the pull rope to the working winch.
  • the rope guide (rope guide) can also be horizontally (possibly also vertically) adjustable (to be moved).
  • a particularly reliable, rope-friendly and trouble-free winding and unwinding of the train cable is guaranteed if the largest possible between the rope guide and working winch Distance exists, so that the lateral forces on the hawser are intercepted by the hawser guide and in the case of a large free rope section, the working winch makes the required lateral change in Hawser for even winding without large lateral counter forces.
  • the free line section is between Guide rail and winch dimensioned such that the length is at least 1 m, preferably is at least 2.5 m, in particular at least 4 to 5 m.
