Definitions

  • The. invention relates to a mounting frame with transmission lines and a telescopic vehicle boom with a mounting frame.
  • transmission lines are often laid, which serve the transmission of hydraulic, electrical and / or pneumatic energy and / or signal transmission, for example, to drive hydraulic or pneumatic cylinders, valves and electric motors or to record readings .
  • it is common ( EP-B-0 623 092 . US-A-3,623,501 ) to use flexible transmission lines, which are guided in a wide arc and whose ends are each fixed to one of the two relatively movable telescope sections.
  • the alignment and guidance of these transmission lines is often difficult. Since the transmission lines are usually bundled, maintenance or replacement are difficult to accomplish.
  • a mounting frame according to the preamble of claim 1 is from the document US-A-3,893,480 already known.
  • the object underlying the invention is seen to provide a mounting frame and a vehicle boom of the type mentioned, by which the above problems are overcome.
  • an improved management of the transmission lines should be possible.
  • the assembly, the arrangement and the orientation of the transmission lines should be simple, easy to install and maintain.
  • an inventive mounting frame with the associated transmission lines, the recordings and the guide for at least one recording is attached to a first telescope section.
  • the ends of the transmission lines associated with the carriage-like receptacle are connected to transmission lines fastened to the second telescope section, while the ends of the transmission lines assigned to the fixed receptacle are connected to transmission lines fixed to the first telescope section.
  • transmission lines can be immovably fixed to the telescopic sections of the jib and guided up to the area of the telescopic overlapping of two adjacent telescope sections.
  • this area terminate the fixed transmission lines and contain connection points, which are designed as couplings, plugs, screw connections or otherwise, and serve the connection with end portions of the mounted on the mounting frame transmission lines, wherein the mounting frame is attached to one of the two telescopic sections.
  • At least one end region of the transmission lines mounted on the mounting frame is fixed to a movable, carriage-like receptacle of the mounting frame and displaceable by means of the guide in the longitudinal direction of the mounting frame. When extending and retracting the boom, this end portion is moved with the slidable receptacle, wherein the elastic arc portion of the transmission lines of the mounting frame compensates for the longitudinal displacements.
  • the mounting frame allows an exact guidance of the transmission lines, which are fixed to the receptacles such that a relative movement of the transmission lines takes place substantially only in the defined region of the elastic sheet.
  • the mounting frame contains all elements of the energy and information transmission and at the same time improves the function of telescoping.
  • the mounting frame can be advantageously formed as a completely pre-assembled component, which allows a simple pre-assembly and facilitates the assembly, the arrangement and the orientation of the transmission lines. Maintenance and Repairs can be carried out easily, for example, by replacing the mounting frame with the associated transmission lines. The replaced mounting frame can be maintained or repaired and can then be reused.
  • the first receptacle is firmly connected to the mounting frame.
  • the fixed to this fixed receptacle end portion of the extension frame side transmission lines is connected to the fixed at the first boom section transmission lines and does not move when extending and retracting the boom.
  • the second receptacle of the mounting frame is guided displaceably on a guide in the longitudinal direction of the mounting frame.
  • the fixed to this movable receptacle end portion of the transmission lines of the mounting frame is connected to the fixed at the second boom section transmission lines.
  • the mounting frame according to the invention can be fastened on the middle boom section.
  • This mounting frame may include a middle, rigidly attached to the mounting frame recording, which supports the transmission lines.
  • the transmission lines each extend in an arc and can compensate for telescopic displacements between the cantilever sections.
  • the transmission lines form at least one substantially J-shaped or U-shaped arc whose leg lengths are adapted to the respective position of the sliding recording.
  • the receptacles are designed as bulkheads, which are aligned transversely to the longitudinal direction and have recesses for receiving and fixing the transmission lines.
  • the end regions of the transmission lines can be fastened, for example, by means of screw connections to the respective bulkhead.
  • At least one of the bulkheads is rigidly attached to the mounting frame and serves as a fixed point for the transmission lines, while at least one other bulkhead can be designed as a slide that can be moved along the guide.
  • the transmission lines end in the region of the receptacles and here have releasable connecting elements, such as couplings, plugs, screw connections and the like for connection to the transmission lines attached to the boom sections.
  • releasable connecting elements such as couplings, plugs, screw connections and the like for connection to the transmission lines attached to the boom sections.
  • the guide has at least two longitudinally extending guide rods which cooperate with corresponding slide bearings of the associated carriage-like receptacle.
  • the sliding bearings preferably have cylindrical bearing surfaces which slide on cylindrical guide rods.
  • the guide includes a longitudinally extending, formed as a profile guide rail on which a corresponding, designed as a slide receptacle is guided.

  • the support wall is preferably a substantially horizontally oriented, arranged under the elbow sheet, on which the line bow can be slidably supported.
  • the clamps can simultaneously serve to fix the inelastic areas of the transmission lines on the mounting frame.
  • the leadership of the transmission lines is improved by the fact that they are not flexible or elastic in the entire area between the recordings. It is of particular advantage to attach at least one receptacle to a rigid transmission line section, which is connected via a connection point with an elastic transmission line section.
  • the transmission lines are elastic only in the area which is designed as a bow and adapts to the extension and retraction of the boom.
  • a good shield against environmental influences, a good management of the transmission lines and a service-friendly training is given by a mounting frame containing a base frame to which the receptacles, the guide and possibly supporting walls are attached, wherein the base frame is closed by a cover through which the transmission lines and the guide against Pollution and accidental contact are protected.
