Definitions

  • the invention relates to a trolley, in particular for chain hoists and / or trailing cables, which comprises a cross-section of the rail consisting of flange and web parts, with opposing wheels and guide rollers which are rotatably supported in side-mounted wheel carriers connected below the cross-section of the rail, with the rail on both sides in front and Behind each impeller that is supported on the flange parts, horizontal guide roller pairs lying on the web of the rail cross section for guidance are arranged and a load suspension device is provided on at least one of the wheel carriers.
  • the invention provides that the one or more running wheels on one side of the rail are offset relative to the one or more running wheels on the other side of the rail in the direction of travel.
  • the running gear according to the invention enables stable running on the running rail, in particular when the load is swinging; Pitching movements and lateral swinging of the chassis are effectively suppressed by the offset of the wheels.
  • a more even running of the running gear on the running rail is achieved if the horizontal guide roller pairs are arranged in pairs directly opposite one another.
  • pairs of horizontal guide rollers should expediently bear on the web of the cross-section of the rail under the action of force, for example caused by a spring force.
  • a compact and robust drive with simple drive attachment results if one wheel is directly motor-driven with two wheels. In this way, the drive can be carried out largely maintenance-free.
  • the running stability of the undercarriage can be further improved in that wheel carrier arms which can be swiveled in or out are pivotably mounted about an axis which extends in the direction of the rail and extends under the rail cross-section, the load being at the level or below the joint formed of the wheel carrier arms which are in each case connected to one another engages on at least one of the wheel carrier arms and the wheel carrier arms are held in a pivoted manner on the guide rail cross section to a limited extent by a closing torque resulting from the load by the guide rollers resting on both sides of the web.
  • this measure enables the running gear in the preassembled state to be carried out on a running rail with a corresponding action in a few simple steps Hang up the cross-section of the rails.
  • the self-adjusting guide rollers which rest against the web on both sides, ensure that the rollers run evenly in parallel, which in turn reduces rolling resistance and therefore wear on the rollers; the guide rollers are also subject to very little wear.
  • the undercarriage pivoted in by the load proves to be very advantageous, particularly when cornering, since this improves the parallel running of the rollers when cornering.
  • the constantly attached guide rollers ensure stable guidance of the undercarriage even when the load is swinging. Changes in the diameter of the running wheels and the guide rollers due to unavoidable abrasion are compensated for within a large tolerance range by the fact that the undercarriage automatically adapts to the running rail.
  • the invention further proposes that the ratio of the vertical distance M of the axes of the impellers and the horizontal distance L of the impellers from the pivot axis is greater than 5 and less than 10.
  • a chassis is shown in front view, which comprises a rail 1, which consists of flange parts 2 and a web 3.
  • the undercarriage itself has two wheel carrier arms 4a, 4b, which are designed as frames 5a, 5b.
  • the frames 5a, 5b are pivotally mounted in opposite directions about an axis 6 which extends in the direction of the rail 1 and runs below the rail cross-section, which enables the frames 5a, 5b to be pivoted open or closed.
  • the wheel carrier arms 4a, 4b can also be rigidly connected to one another and set at a fixed distance.
  • Fig. 1 shows that in the upper region of the frame 5a, 5b a pair of opposing wheels 7 are arranged, the axes of rotation of which run horizontally and are supported in the frame 5a, 5b.
  • an impeller is driven directly by a motor 7a.
  • the wheels 7 roll. on the lower flange part contact surfaces 8.
  • the frames 5a, 5b accommodate, in addition to the wheels 7, which are arranged centrally in the frames 5a, 5b, in front of and behind the wheels 7, horizontal guide roller pairs 9, 9, which consist of individual guide rollers 9, which are supported in the frame 5a, 5b in a vertically rotatably mounted manner.
  • the load generates a closing moment in the frames 5a, 5b, which causes the frames 5a, 5b to pivot, by means of which the guide rollers 9 are held pivoted in on the web 3 of the cross-section of the running rail.
  • the angular position between the frames 5a, 5b is limited in FIG. 1 by the guide rollers 9 resting on the web 3 on both sides; the guide rollers 9 are placed under the force of the load itself.
  • the ratio of the vertical distance M of the axes of the impellers (7) and the horizontal distance L of the impellers (7) from the axis (swivel axis) 6 is greater than 5 and less than 10.
  • guide grooves on the web 3 which extend in the longitudinal direction of the rail 1 and in which the guide wheels 9 are guided.
  • the additionally arranged guide grooves ensure an even more stable guidance of the chassis when the load is swinging.
  • FIG. 2 shows a top view of the undercarriage with the travel rail according to FIG. 1.
  • the impeller 7 of the one frame 5a or 5b is offset from the impeller 7 of the other frame 5b or 5a in the direction of travel, as can be clearly seen in FIG. 2.
