Definitions

  • the invention relates to a guide device for a with wheels provided crane on a crane runway with crane rails according to the preamble of claim 1.
  • Such a guide device is already known from DE-A-1 431 951.
  • a drive includes one Head carrier that holds two or more wheels.
  • the two headbands of the crane are connected by the crane girder.
  • Wheel flanges are provided on the running wheels on the crane rails.
  • the invention is therefore based on the object of a guide device of the type mentioned above, which is capable of large Compensate for track dimension deviations of the crane runway, being ensured should be that the impellers here in their intended position on the Crane tracks of the crane runway remain.
  • the task is solved by a guide device, which has two guide rollers, which are opposite each other in the area the flanks of the crane rail are held by a bracket, the Bracket movable and movable transversely to the longitudinal axis of the crane rails is noticeable.
  • the guide device is in this case on the face of the head carrier arranged of the crane.
  • Impeller comes from the area of the crane rail.
  • the wheels of a crane are not more have to be provided with wheel flanges. Because the function of Wheel flanges are taken over by the console with the guide rollers.
  • each Cologne cylinder drive at least one, but preferably two valves are associated with a supply facility, for example an oil container.
  • Such control includes another advantageous feature of the invention sensors, the sensors the Determine the current position of the impeller relative to the crane rail. The means that the position of the impeller relative to the sensors Crane rail is then determined in the event that the impeller is too far deviates from the ideal line on the crane track of the crane runway Lock the cylinder of the console, so that another side drift the impeller on the crane rail to prevent.
  • the Cranes sensors are arranged.
  • the arrangement of the sensors is such that at each end of the head girder on either side of the crane rail one sensor each is arranged on the head carrier. Through these sensors the position of the head carrier and therefore the position of the wheels of the Cranes continuously monitored.
  • the arrangement of the Sensors is located on both ends of the other head carrier, i.e. on the head carrier, which has no sensors, one on each end Guide device. From this it is clear that the one head carrier Sensors are assigned, whereas the other, opposite Head carriers with the appropriate guide Guide rollers are assigned assigned consoles.
  • the one designated as a whole has 1 Guide device, the housing 10, the console 20 and the Guide rollers 30, 40 on both sides of the crane rail 50 through the Console 20 are held.
  • the housing 10 of the guide device is attached to the front of the crane's head girder.
  • the console 20 consists of a box-shaped structure 21 which the two axes 31st and 41 of the rollers 30, 40 rotatably receives.
  • the console 20 is through the horizontally displaceable slide 11 with the housing 10 connected.
  • the two piston-cylinder drives are located in the housing 10 15, 16, the piston rods 15a, 16a of the piston-cylinder drives each engage a coupling element 13.
  • This element 13 is mounted in two housing plates 17, 18. These housing plates are again arranged on the carriage 11.
  • the carriage 11 is in the Housing 10 stored in that this lateral guide strips 11a has that can be slidably received in the housing 10.
  • Each of the piston-cylinder drives 15, 16 stands by two valves 61, 62 or 71, 72 with an oil tank 80 in connection.
  • the valves 61, and 71 are designed as one-way solenoid valves, the valves 62, 72 as Check valves. The type of formation of the valves results in Individuals from FIG. 6.
  • FIGS. 4 and 5 schematically represent one Crane girder 200 of a crane with two head girders 210 and 220 Head carriers each take two wheels in a row that are not are shown.
  • the Guide devices 1 At both front ends of the head support 220 are the Guide devices 1 with the guide rollers 30, 40 arranged.
  • the sensors are also in the Area of the respective front end of the head carrier arranged. A the corresponding numbering is shown in Figure 5.
  • the sensor 310, 312 reaches the area of the crane rail 50.
  • the console presses with the guide roller 30 seen in the direction of travel (arrow 400) behind the head support 220 according to the arrow 250 on the flank of the rail 50, whereas the Guide roller 40 of the console in front of the head carrier on the opposite edge of the crane rail 50 rests (arrow 250).
  • sensors 312 and 311 are in the area of crane rail 50 reach. From this it is clear that the crane rails 50 at a such guiding device no longer experiences any horizontal forces, and also completely dispenses with wheel flanges on the wheels can be because the impellers are guided by the guide rollers, and large track deviations of the crane runway can also be compensated for can.
