Definitions

  • the invention relates to a construction work device according to the preamble of claim 1 with a mast, arranged at the head of the mast deflection device for guiding at least one cable or a line, wherein the deflection device has a first, front guide roller, and a second, rear guide roller, and a Pivoting device, with which the deflection device can be pivoted from an operating position into a transport position.
  • a generic construction work device is known from DE 101 23 403 A1.
  • This document teaches a construction work tool with a mast, at the upper end of a mast head is mounted.
  • This mast head has at least two Seilumlenkrollen, by means of which working cables of the construction equipment are guided around the mast head.
  • To facilitate the transport of the entire construction equipment of the mast head together with the two pulleys by means of a pivoting device between a working position and a transport position on the mast is pivotable.
  • the clear height of the construction equipment can be reduced when the mast is brought to transport the construction equipment in an approximately horizontal position.
  • the object of the invention is to provide a particularly compact and easy to transport construction work device.
  • the construction work device according to the invention is characterized in that the front deflection roller is pivotally mounted relative to the rear deflection roller.
  • a basic idea of the invention can be seen in that by means of the pivoting device, the relative position of the front deflecting roller with respect to the rear deflecting roller is variable, i. that the two deflection rollers are pivotable to varying degrees by means of the pivoting device. This makes it possible to bring the two pulleys independently in a particularly favorable in terms of the transport dimensions of the construction work device, whereby a particularly compact and easily transportable construction work device can be obtained.
  • the cable or the line runs on the front guide pulley in the deflection and on the rear pulley from the deflection of.
  • the rear pulley is preferably in the rope course windward side and the front pulley arranged on the load side of the head of the mast.
  • the rope or the line run at least approximately parallel to the longitudinal direction of the mast in the front guide pulley and out of the rear guide pulley.
  • the construction work device may be designed such that the rope is guided from the front deflection roller directly to a load, for example a soil cultivating device, i. that between this pulley and the load no further pulleys in the rope course are available.
  • the construction work apparatus is preferably used for tillage.
  • both the front deflection roller and the rear deflection roller can be pivoted by means of the pivoting device.
  • the rear guide roller mounted firmly on the mast is.
  • This embodiment is based on the idea that the transport dimensions of the construction work device, in particular its clear height, often be determined only by the position of the front pulley on the mast with folded mast.
  • the rear pulley is often not in front of the total cross-section of the construction work device and thus contributes at most insignificantly to the transport dimensions of the construction work device. For this reason, it may be advantageous that only the front deflection roller is pivotable by means of the pivoting device, whereas the rear deflection roller is arranged pivotably on the mast.
  • a structurally particularly simple construction work device is characterized in that the pivoting device has a boom, which is pivotably articulated on the head of the mast, and on which the front deflection roller is rotatably mounted.
  • the boom is pivotable about a pivot axis on the mast, which extends at least approximately parallel to the axis of rotation of the front and / or rear pulley.
  • the pivoting device has a hydraulic cylinder which is articulated on its one side on the boom and on its other side to the head of the mast.
  • a particularly compact pivoting device can be obtained thereby, that the longitudinal axis of the hydraulic cylinder is arranged at least in the operating position of the deflecting at least approximately parallel to the cable course or line course between the front and the rear guide roller.
  • a spindle or chain drive or other drive can be used.
  • a structurally particularly simple construction work device is further given by the fact that the joint axes of the hydraulic cylinder extend at least approximately parallel to the axes of rotation of the deflection rollers.
  • the joint axes are understood to be the axes of the articulation of the hydraulic cylinder on the boom and on the mast.
  • one of the two hinge axes coincides at least approximately with the axis of rotation of the rear guide pulley.
  • the front deflection roller projects forwardly on the mast and is set back in the transport position, in particular with respect to the mast front side.
  • a particularly small clear height in the transport position with a particularly simple cable course in the operating position can be given by the fact that the axis of rotation of the front guide pulley in the operating position of the deflector is located in front of the longitudinal axis of the mast and in the transport position on or behind the longitudinal axis.
  • the longitudinal axis can be understood as meaning any axis that runs longitudinally through the mast within the mast cross-section.
  • the longitudinal axis can in particular run through the center of gravity of the mast. It preferably represents an axis of symmetry of the mast.
  • a construction work apparatus that is particularly suitable for soil cultivation is characterized in that a guide device is provided for guiding a soil cultivating device along the mast.
  • the tillage implement may be, for example, a worm borer or even a Fräs coupled act.
  • the guide device may in particular have a drive for rotationally driving the soil cultivating device about its longitudinal axis.
  • the front deflecting roller In order to be able to attach the harrow to the rope in a particularly simple manner, it is advantageous for the front deflecting roller to be aligned tangentially with the longitudinal axis of the soil cultivating device in the operating position of the deflecting device. This may in particular be understood as meaning that a tangent to the front deflection roller lies on an extension of the longitudinal axis of the soil cultivation device.
  • a further advantageous development of the invention resides in the fact that the front deflecting roller is arranged above the rear deflecting roller, both in the operating position and in the transport position of the deflecting device in the longitudinal direction of the mast. This is understood to mean that the front deflection roller is farther away from the mast base in both positions than the rear deflection roller.
  • the rear guide roller is mounted by means of a fixed arm at the head of the mast, wherein the fixed arm is in particular shorter than the boom of the pivoting device.
  • a further preferred embodiment of the invention consists in that an auxiliary roller is provided for guiding an auxiliary rope, which is pivotably mounted by means of a jib on the pivoting device, in particular on the boom.
  • auxiliary role further roles may be provided for guiding and deflecting the auxiliary rope on the head of the mast, wherein the axes of rotation of these other roles preferably coincide with the axes of rotation of the front and / or the rear guide pulley. Due to the pivotable mounting of the Help role, the transport dimensions of the construction work device can be further reduced.
  • an auxiliary hydraulic cylinder may be provided which is articulated on the one hand on the jib and on the other hand on the boom.
  • a pivoting of the auxiliary roller can also be effected, for example, by gravity acting on the auxiliary roller and the auxiliary boom during pivoting of the pivoting device and / or the mast.
  • a rigid locking bar is provided, with which the jib can be fixed to the boom. This locking bar is suitably hinged on one side on the jib and fastened on the other side for fixing the jib on the boom.
  • the locking bar can also be articulated on the boom and fastened to the jib.
  • a trailer is provided, on which the mast, preferably pivotally mounted, is arranged.
  • the mast is pivotable from a vertical operating position, in which it extends at least approximately vertically, into a transferred transport position, in which the mast extends at least approximately horizontally.
  • FIG. 1 An embodiment of a construction work device according to the invention is shown in Fig. 1 and partially in Fig. 2.
  • the construction work device has a construction vehicle designed as a tracked vehicle 80, on which a mast designed as a mast 1 is pivotally articulated about a substantially horizontally extending pivot axis via a pivot joint 81.
  • a hydraulic swivel cylinder 82 is provided, which is articulated on its one side to the lower half of the mast 1 and on the other side of the trailer 80.
  • the mast 1 is in a vertical operating position, in which the longitudinal axis 9 of the mast 1 extends substantially vertically to the ground surface 90. In this operating position, the construction work apparatus is provided for soil cultivation.
  • the mast 1 is pivoted to a transport position with reduced outer dimensions.
  • the longitudinal axis 9 extends approximately horizontally with respect to the bottom surface 90.
  • the construction work apparatus further comprises a cultivator 73, consisting of a worm borer 75 and a telescopic boring bar designed as a kelly bar 74, on which the auger drill 75 is arranged on the bottom side.
  • the cultivator 73 is displaceably guided on its Kelly bar 74 by means of a guide device 70 on the mast 1.
  • a displaceability is given in the direction of the longitudinal axis 77 of the cultivator 73, which extends at least approximately parallel to the longitudinal axis 9 of the mast 1.
  • the guide device 70 also has an unspecified rotary drive for rotationally driving the soil cultivating device 73 about its longitudinal axis 77.
  • the construction work device has a cable 12 designed as a steel cable, which is connected to the soil cultivating device 73 at an attachment point 14 provided at the top of the soil cultivating device 73. From the attachment point 14, the cable 12 extends to a first, front guide pulley 21, which at the head 6 of the mast 1, i. at the upper end of the mast 1, is rotatably mounted. To this front guide roller 21, the rope 12 is guided around and extends from there to a rear guide roller 22, which is also arranged on the head 6 of the mast 1. Also around this rear guide roller 22, the cable 12 is guided around and runs from there via a further guide roller 26 which is arranged in the lower half of the mast 1, to a rear side of the trailer 80 arranged winch 27th

In the transport position shown in Fig. 2, however, the front guide roller 21 is pivoted about the pivot joint 31 in a rear transport position in which the axis of rotation 54 of the front guide roller 21 is offset from the longitudinal axis 9 of the mast 1 to the rear. In this transport position, the front guide roller 21 is no longer protruding from the mast 1, but is arranged backwards relative to this. As can be seen in Fig. 2, in this transport position with folded mast 1, the clear height of the construction work device is reduced.
  • a hydraulic cylinder 32 is provided which is articulated by its piston rod on the boom 30 and is articulated on the side of its cylinder housing on the fixed boom 42.
