Definitions

  • the invention relates to a chassis, in particular for chain hoists, load suspension devices and / or trailing cable, the one consisting of flange and web parts
  • Rail section includes, on which opposing wheels and Support guide rollers in the side, below the cross-section of the runway connected wheel carriers are rotatably mounted and of which the guide role on both sides of the rail in front of and behind each one that rests on the flange parts
  • the impeller is in contact with the guide rail cross-section Are horizontal guide roller pairs, on which at least one of the wheel carriers one Has load suspension device.
  • the solution provides that the guide wheels in at least one side of the web of the guide rail cross section arranged guides at least in sections are led.
  • the chassis enables one, especially with a swinging load stable running on the running rail; Nodding movements and lateral oscillation of the Chassis are effectively prevented by the guides.
  • the guides are designed as guide grooves.
  • a stable and quiet guidance is achieved in that the contour of the Guide grooves for the shape of the guide wheels running in the guide grooves is complementary.
  • cross-section of the guide grooves be substantial is trapezoidal in order to additionally minimize wear To achieve guide wheels.
  • edges of the guide wheels be rounded are formed, so run only partially on the surfaces of the guide grooves.
  • the guide is stabilized with little wear, especially when 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 on the slopes of trapezoidal guide grooves run, leaving a gap between the guide wheels and the central 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 the Contact rail cross section apply force, for example by a Spring force.
  • the run is particularly improved in that up or in pairs Swiveling wheel carrier arms around in the direction of the running rail extending and pivoting under the cross section of the running rail are stored, the height at or below the joint formed interconnected wheel carrier arms the load on at least one of the Engages the wheel carrier arms and the wheel carrier arms by one coming from the load Closing moment of those in the guides on the web on both sides Guide rollers are kept pivoted in on the cross section of the guide rail.
  • a chassis is shown in front view, which comprises a rail 1, which consists of flange parts 2 and a web 3.
  • the chassis itself has two Wheel carrier arms 4a, 4b, which are designed as frames 5a, 5b.
  • the frames 5a, 5b are around an extending in the direction of the rail 1 and under the Track cross-section axis 6 pivotally mounted, which is an opening or Swiveling the frame 5a, 5b allows.
  • the wheel carrier arms 4a, 4b can also be rigid be connected. It is also a combination of these two Variants conceivable, which consists in that the pivotable wheel carrier arms 4a, 4b after swiveling on the rail 1 are fixed so that a rigid Connection between the wheel carrier arms 4a, 4b is made.
  • Fig. 1 shows that in the upper region of the frame 5a, 5b, a pair opposite impellers 7 are arranged, the axes of rotation of which are horizontal run and are supported in the frame 5a, 5b. Of the two impellers 7 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 take in addition to the Frame 5a, 5b each centrally arranged wheels 7 in front and behind the Impellers 7 arranged horizontal guide roller pairs 9, 9, which consist of individual Guide rollers 9 exist, which are vertically pivoted in the frame 5a, 5b are supported. While the impellers 7 are on the lower flange parts 2 support, the guide rollers 9 are in pairs on the web 3 of the rail 1.
  • the load generates a closing moment in the frames 5a, 5b, which causes the Frame 5a, 5b causes the guide rollers 9 on the web 3 of the Track cross section are kept swung.
  • the angular position is between the frames 5a, 5b in Fig. 1 by the web 3 on both sides adjacent guide rollers 9 limited; the guide rollers 9 are in contact acted upon by the load itself.
  • FIG. 2 is a top view of the undercarriage with the travel rail according to FIG. 1 shown.
  • the web 1 of the rail 1 shown is in Longitudinal direction of the rail 1 extending lateral guides 11 for the Guide wheels 9 formed in the form of guide grooves 11a, in which the Guide wheels 9 guided to generate a stable running gear under power are.
  • 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 is the Guide grooves 11a substantially trapezoidal with two bevels 13 and one Trapezoidal roof 14 is formed, the curves of the edges 12 of the guide wheels 9 run on the slopes 13 of the trapezoidal guide grooves 11a, namely under Leaving a space 15 between the central region of the Guide wheel 9 and the trapezoidal roof 14, i.e. the interfaces between Guide wheel 9 and guide groove 11a are relatively small, which is reduced Rolling resistance of the chassis ensures.
  • the ratio of the vertical distance M of the axes of the impellers 7 and that horizontal distance L of the wheels 7 from the axis 6 (swivel axis) is greater than 3 and less than 10.
