Definitions

  • the invention relates to a displacement device, in particular for construction machinery, with a guide, a carriage, which is slidably mounted on the guide, a Stellzylinder for moving the carriage, wherein the Stellzylinder one of a cylinder housing extendable Piston rod, and a support member for securing the Piston rod against buckling.
  • Moving devices come for example on construction machinery used for civil engineering, in which about a drill or a jogger along a vertical mast through the Actuator is moved vertically.
  • a construction machine is described for example in DE 198 13 902 C1.
  • About the actuating cylinder can so when lowering the Drill or the vibrator exerted a desired pressure force which are necessary for the necessary work progress provides.
  • actuating cylinder with a long stroke length of up to 5 m and more needed. This requires correspondingly long piston rods of the Actuating cylinder.
  • the invention has for its object to provide a displacement device in which the risk of buckling a piston rod is reliably counteracted in a simple manner.
  • the displacement device according to the invention is characterized that the support element both on the piston rod as also slidably mounted on the guide or the carriage is, and that the support element during extension of the piston rod up to a predetermined support position on the piston rod is displaceable.
  • a basic idea of the invention resides in the piston rod to provide a displaceable support member which the piston rod in a particularly critical position with the leadership or the sled couple. This will be at the support position the rigidity and thus the security against a Buckling increased.
  • Compared to known displacement devices can by the inventive arrangement of Supporting element with the same or even increased buckling safety a smaller diameter piston rod and thus a cheaper Stellzylinder be used.
  • the displacement device for the displacement device according to the invention any type of adjusting cylinders, for example a pneumatic cylinder, be used. But according to the invention it is particularly advantageous that the actuating cylinder is a hydraulic cylinder is. Because just hydraulic cylinders are used for application high forces, which leads to a corresponding risk of Kinking the piston rod lead.
  • a preferred embodiment of the displacement device according to the invention is that the actuating cylinder on the one hand hinged to the guide and on the other hand on the carriage and is arranged parallel to the guide. At this Arrangement is a good power transmission through the actuator cylinder on the sled while maintaining good mobility the support element on the piston rod and the guide or the carriage reached.
  • the support element preferably has Gleitbüchsen or sliding shoes, with which the Support element along the piston rod or the guide slidably is stored.
  • the support element via a light Clamping on the piston rod with this be slidable.
  • a particularly low-wear version of the displacement device is achieved according to the invention that to move of the support element arranged a driver on the carriage is.
  • the driver is attached to the carriage, that when reaching the final position of the carriage the sliding bearing support element through the driver up to the desired support position is performed.
  • retracting the Piston rod can through the support element in a simple manner the head of the piston rod together with the slide in the retracted retracted initial position.
  • the leadership is arranged. This is especially useful if the support element by static friction on the piston rod or by gravity action, for example when the piston rod is extended vertically downwards.
  • a stop ensures a defined position of the support element in the desired support position.
  • the support member the piston rod completely encompassing.
  • a Gleitbüchse be used, which mounted on the piston rod is.
  • the slide bush is then in a corresponding Bearing opening of the support element attached.
  • the displacement device according to the invention be used in different areas. Also at smaller stroke lengths, the invention can be used, it is essentially based on the ratio between the maximum Force of the piston rod length, the piston rod diameter and the required buckling arrives. There the cost of adjusting cylinders with increasing size increase significantly, is the use of the invention Displacement device, in particular from stroke lengths of 1 m and more particularly economical.
  • a high efficiency is inventively in a Construction machine reached, in which the guide to a in operation vertical mast is formed and the piston rod along the mast downwards extendable.
  • the shifting device is in particular for rotary drilling rigs for Creating foundation piles used in the ground.
  • the support element can be stored in a sliding manner and is by gravity moved to the support position.
  • a displacement device is shown 10 in a partially shown drill for lowering shown by drilling for foundation piles.
  • a vertical Mast 42 which usually with a superstructure of a Construction vehicle is one trained as a rail Guide 12 arranged.
  • a Carriage 14 Along the guide 12 is a Carriage 14 via two encompassing sliders 15 vertically slidably mounted.
  • a Rotary drive 44 housed, with which in a known manner a drilling tool, such as a drilling screw, driven in rotation becomes.
  • an actuating cylinder 20 is provided. Whose Cylinder housing 22 is hinged to the mast head, while the in Cylinder housing 22 extendable mounted piston rod 24 with her head 25 is hinged to the carriage 14.
  • the support member 16 extends transverse to the piston rod 24 to the guide 12, at which the support member 16 via a slide shoe 18 also sliding is slidably mounted.
  • the support member 16 remains in the position shown in Figure 1, to a stop surface on the head 25 of the piston rod 24 rests against the support element 16 and this entrains the further retraction of the piston rod 24 and goes up.
  • the support member 16 In the retracted position of the piston rod 24 is the support member 16 on the one hand to a stop flange 23 of the cylinder housing 22 and on the other hand the head 25 of the piston rod 24 at.
  • Another displacement device 10 is in Connection with a marker device shown in FIG explained.
  • a guide 12 is arranged, along which the mecanicados pronouncekler forming carriage 14 is vertically movable.
  • a guide rail 13 which in conjunction with the guide 12 ensures a defined linear movement.
  • a cylinder housing 22 of an actuating cylinder 20 attached, which is parallel to the guide 12 and the guide rail 13 extends, wherein the cylinder housing 22 mounted piston rod 24 at its upper end with the head of the carriage 14 is connected.
  • a support member 16 is both along the piston rod 24 as well as along the guide rail 13 of the carriage 14 slidably mounted.
  • the support element When extending the piston rod 24, the support element remains 16 initially in its position on the stop flange 23 until the by the piston rod 24 upwardly moved carriage 14 with a driver 26, the underside of the support member 16 contacted and this now moves up with.
  • the driver 26 is arranged on the carriage 14 such that in the maximum extended position of the piston rod 24 the Support member 16 is arranged approximately centrally. In this embodiment is the definition of the support position yet supports that another upwards process of the support element 16 by a downwardly directed elongated counter-attack 29 prevents which when reaching the support position acts against a stop 28 on the scent insomniakler.
