Definitions

  • the invention relates to a trolley, in particular for chain hoists, load suspension devices and / or trailing cables, which comprises a rail cross-section consisting of flange and web parts, on which opposing running wheels and guide rollers are supported, which are rotatably mounted in lateral wheel carriers connected below the rail cross-section and of which the guide roller on both sides of the rail in front of and behind each impeller which is supported on the flange parts are horizontal guide roller pairs which are in contact with the guide rail cross section and on which at least one of the wheel carriers has a load suspension device.
  • the solution provides that the guide wheels are guided at least in sections in guides arranged at least on one side of the web of the rail cross section.
  • the running gear enables stable running on the running rail, especially when the load is swinging;
  • the guides effectively prevent pitching movements and lateral swinging of the undercarriage.
  • the guides are designed as guide grooves.
  • a stable and quiet guidance is achieved in that the contour of the guide grooves is complementary to the shape of the guide wheels running in the guide grooves.
  • the cross-section of the guide grooves be substantially trapezoidal in order to additionally minimize wear on the guide wheels.
  • edges of the guide wheels are rounded, so that they run only partially on the surfaces of the guide grooves.
  • the guide is stabilized with little wear and tear if the rounding of the edges of the guide wheels and the shape of the trapezoidal guide grooves are designed such that the guide wheels run on the slopes of the trapezoidal guide grooves, leaving a space between the guide wheels and the middle one Area of the associated guide groove.
  • a smooth run is also achieved in that the horizontal guide roller pairs in the guides on the web of Contact rail cross section apply force, caused for example by a spring force.
  • the run is particularly improved in that wheel carrier arms which can be swiveled in or closed in pairs are pivotably mounted about an axis which extends in the direction of the rail and extends below the rail cross-section, the load on at least one at the level or below the joint formed in each case of the wheel carrier arms which are connected to one another the wheel carrier arms engages 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 originating from the load by the guide rollers resting on both sides in the guides on the web.
  • 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 pivotably mounted about an axis 6 which extends in the direction of the travel rail 1 and runs below the cross section of the travel rail, 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.
  • 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 impellers 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.
  • FIG. 2 shows a top view of the undercarriage with the travel rail according to FIG. 1.
  • lateral guides 11 for the guide wheels 9, which extend in the longitudinal direction of the rail 1, are formed on the web 3 of the illustrated guide rail 1 in the form of guide grooves 11a, in which the guide wheels 9 are guided to generate a stable running gear .
  • Fig. 3 shows an enlarged section of the guide grooves 11a together with a guide wheel 9 engaging in the guide grooves 11a with rounded edges 12 in cross section.
  • the cross section of the guide grooves 11a is essentially trapezoidal with two bevels 13 and a trapezoidal roof 14, the rounded edges 12 of the guide wheels 9 running on the bevels 13 of the trapezoidal guide grooves 11a, while leaving them an intermediate space 15 between the central region of the guide wheel 9 and the trapezoidal roof 14, ie the contact surfaces between the guide wheel 9 and guide groove 11a are relatively small, which ensures a reduced rolling resistance of the chassis.
  • 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 6 (swivel axis) is greater than 3 and less than 10.
