Definitions

  • the invention relates to a scraper device for a concrete preparation plant, consisting of a control station mounted on a turntable on the plant, a cantilever projecting over the aggregate storage, possibly an attached to the rear of the operating position, front overlapping boom, on which the boom is braced, and a two-drum winch arranged on the control station for two ropes guided over guide rollers on the front of the control station, one of which is guided directly as a pulling rope, the other as a retractor along the extension arm via a deflection roller mounted at the tip thereof to a scraper bucket.
  • scrapers are used for both mobile and stationary concrete preparation plants.
  • the entire scraper with control station is stored as a separate unit on the slewing ring on a corresponding frame of the system, so that it can be moved from one system to another or dismantled for the purpose of transporting the system.
  • the scraping bucket By means of the traction cable, the scraping bucket is pulled over the slope of the aggregate storage and takes up material in order to pour it onto, for example, a metering trough located at the level of the control station. From there, the material reaches the processing plant. During this scraping process, the retraction egg 1 is carried loose. The other drum of the winch is then driven in order to pull the pull-back rope and thereby pull the scraper outwards in a position lifted off the slope. By releasing the retraction cable again, the scraper bucket is lowered back onto the aggregate storage so that a new scraper game can begin.
  • the two-drum winch is integrated in the control station and is difficult to access there.
  • the accessibility is particularly difficult in that the seat for the operator, a steering wheel for rotating the scraper, two brake levers for the two drums and two hand levers for actuating the drum drive or the associated clutches are arranged on the control station in a confined space. Accessibility is further made more difficult if the entire control station is protected from the weather like a cabin.
  • the invention has for its object to improve the accessibility of the two-drum winch and its drive in a scraper of the construction described above.
  • this object is achieved in that the winch is arranged on the outside at the rear of the control station.
  • the two-drum winch with its drive is accessible from the outside, so that maintenance work, for example oil change, replacement of clutch discs, rope inspection, etc., without hindrance can be carried out by other parts of the system.
  • This arrangement has the further essential advantage that the cable deflection between the guide rollers arranged on the front of the operating position and the two drums of the winch is more favorable since the angle of deflection is reduced due to the increase in the distance between the guide roller and the drums. So the rope load is reduced. In addition, the risk is reduced that the rope lies on top of one another during winding. Since the drive of the two-drum winch has a significant weight, this results in a favorable counterweight to the boom or scraping bucket.
  • the winch is arranged on the outside at the lower part of the gallows and is covered by a suspended hood. This also improves accessibility.
  • the scraper device designated as a whole by 1, is rotatably mounted on the frame or structure of a concrete preparation plant, not shown, via a slewing ring 2. It has an operating station 3, on the front of which a bracket 4, which in the installed position projects from an aggregate storage located underneath, is supported.
  • a gallows-shaped support 5 is attached to the back of the control station 3, on which the boom 4 is braced using soap 6.
  • the gallows 5 is constructed from profiles and consists of a lower section 7 with an upper end flange 8 (see FIG. 1) and an upper part 9 with a lower end flange 10.
  • the upper part 9 is detachably connected to the lower section 7 by screws 11 assemble or disassemble separately from it. Otherwise, the profiles are covered by a sheet metal cladding 12 which is drawn on the outside over the flanges 8, 10 and welded there.
  • the pull cables 6 are anchored at 14 on the upper part 9.
  • the control station 3 has a floor frame 15 on which a cabin 16 for an operator is arranged. Operating elements for pivoting or rotating the scraper device and for accelerating or braking a scraper bucket 17 are accommodated in the cabin.
  • the scraper bucket 17 is guided by a pull rope 18 and a return rope 19, which are driven by a two-drum winch 20 (FIG. 2).
  • Each drum has a clutch 21 and a brake drum 22.
  • the two-drum winch 20 is attached to the rear of the control station 3, specifically on the outside of the lower part 7 of the gallows-shaped support 5.
  • the drive motor (FIG. 1, not shown) is arranged directly above the two-drum winch 20.
  • the entire winch assembly is covered by a hood 23 which can be detachably attached to the lower part 7 of the support 5.
  • a traction rope 18 which rolls at the front of the control stand between Lei 24 directly to the scraper bucket 17 and / is attached there.
  • the return rope 19 is wound up, which is also guided over guide rollers 25 on the front side of the floor frame 15 of the control station 3, then along the boom 4 to a deflection roller 26 at the top of the boom and from there to the rear wall of the scraper bucket 17 is attached there.
  • the two-drum winch 20 and its drive motor as well as the brake drums 22 and the clutches 21 are easily accessible from the outside. Furthermore, as indicated in FIG. 2, there is a favorable deflection angle for the pull rope 18 and the return rope 19. Finally, a large part of the weight is shifted backwards and thus acts as a counterweight to the boom 4 and the scraper bucket 17.
