Definitions

  • the frame structure and the compensating rockers are provided with pairs of abutments with the abutments of one and the same pair being located one above the other and offset in the travelling direction of the implement with regard to the pivotal connection of the frame structure with the compensating rockers, the abutment of each pair of abutments being so arranged or adjustable that they prevent a tilting of the frame structure in the pivotal connection of the frame structure with the compensating rockers or limit such tilting to a predetermined angle.
  • the present invention relates to an upwardly extend ing implement or device. especially a gantry and a bridge crane.
  • the framework of which rests in an articulated manner on compensating or balancing arms of carriages on rails.
  • the framework has a rectangular or triangular supporting base the corner points of which are located in the centers of the joints by means of which the balancing arms are connected to the framework.
  • below each corner point of the supporting base there are provided a plurality of balancing arms in such a manner one above the other that each compensating or balancing arm rests at each end on two shorter compensating arms.
  • tilting moments are counteracted by the moment which results from the weight of the masses taking part in the tilting and. more specifically, this moment counteracts the tilting moments with a lever arm which equals the horizontal distance of the masses from these corner points.
  • This lever arm is. however. the shorter the smaller the corner distance is selected for reducing the above referred to clearance.
  • FIGS. I. 2 and 3 illustrate for three different embodi ments of the invention the side views of gantries with the carriage systems located below one or two corner points. and also illustrate those parts of the crane framework which are adjacent to these corner points.
  • the implement according to the present invention the framework of which rests in an articulated manner in corner points of a supporting base on compensating arms of rail carriages. is characterized primarily in that on the framework and on the compensating arms there are provided abutments which are located in pairs opposite to each other and in the direction of the rails are relative to the corner points of the supporting base off set in such a way or adjustable in such a manner that they will prevent the tilting ofthe framework in the corner points or will limit such tilting to a predetermined extent.
  • the gantry crane shown therein rests in all embodiments with its carriages on two rails 1 which are spaced from each other in conformity with the large span of the crane.
  • Each of the supports of the crane framework located above one of the rails has a long travelling beam 2 the ends of which have arranged thereon upwardly converging legs 3 provided in sheet metal box manner.
  • the beam 2 rests by means of downwardly directed extensions in joints 4 on main rockers.
  • the axes of the joints 4 extending in a direction transverse to the travelling direction.
  • the centers of the joints 4 form the corner points of the supporting base for the crane framework.
  • the supporting base forms a rectangle one side of which equals the corner distance e.
  • FIGS. l and 2 which means the distance between the two corners E located above one and the same rail 1.
  • One half of the corner distance Vac is shown in FIGS. l and 2 and extends from one corner point E to the vertical central plane M of the crane which central plane extends in a direction transverse to the rails 1.
  • the main compensating rocker 5 forms a two-arm lever with equal lever arm lengths.
  • the rocker 5 rests on its ends in joints 6 of further shorter compensating rockers 7 which likewise have lever arms of equal length.
  • the rockers 7 rest at their ends on two further still shorter compensating rockers 8 having lever arms of equal length.
  • Rockers 8 rest at their ends by means of supports or bearings 9 on the central portion of compensating bogies 10 each of which has two serially arranged wheels or wheel pairs ll. In this way the wheels or wheel pairs ll are in the carriage system located below each corner point E supported on the rail 1 or on two adjacent rails.
  • a buffer 12 which projects outwardly beyond the outermost wheel 11.
  • extensions 13 At the end faces of the travelling beams 2 there are provided extensions 13. Below the extensions [3 supports or dogs [4 are mounted on the main rockers 5. To the bottom side of each extension 13 and to the top side of each dog 14 there are connected abutment plates 15. In the normal position of the main rockers 5. i.e.. when their planes passing through the centers of the joints 6 have not been moved out of their horizontal position due to an unevenness of the rail route. the abutment plates generally indicated by numeral 15 are separately identified by reference designations 15a and 15b and at each corner point E these are vertically spaced from each other by the distance a.
  • the distance a has been selected so as to be just large enough to permit such tilting of the main rocker 5 while pivoting movements of the framework in the joints 4 will be limited.
  • the lever arm of the weight moment which acts counter to the tilting moment due to wind forces may. if necessary. be increased by the distances 1' or it when also the tilting movements of the main compensating rockers 5 are by corresponding abutments limited relative to those compensating rockers 7 which are facing away from the central plane M. and when the tilting movements of the rockers 7 are limited relative to the compensating rockers 8 facing away from the central plane M.
  • the upper abutment plate 15. which in conformity with FlG. l is firmly mounted on the extension 13, has been replaced by a punch or plunger 16 which by means of a piston reciprocable in a cylinder 17 of a hydraulic power device is guided in vertical direction.
  • the cylinder [7 of the hydraulic power device which is mounted in an extension 18 extending from the travelling beam 2 toward the left. has its upper end and its lower end connected to a control device 21 by conduits l9 and 20 respectively.
  • the control device 21 is on the one hand in com munication with a pressure storage device 22 to which fluid under pressure is conveyed through a check valve 24.
  • a discharge conduit 25 leads from the control device 21 to a liquid container 26.
  • the piston is adapted in the cylinder 17 to be acted upon from above by pres sure fluid so that the punch will be moved downwardly until it engages the abutment plate 15 on the respective dog of the main compensating rocker 5.
  • the conduit 19 is shut off. the punch cannot escape in upward direction. Consequently. the framework will be prevented from tilting from the right toward the left under the influence of wind forces in the joints 4 shown on the left-hand side in FIG. 2 relative to the main compensating rocker 5.
  • an initial tilting movement is permitted. until the upper abutment plate 15 abuts the lower abutment plate.
  • a common hydraulic device 2i 25 is employed for the two cylinders 17 at both ends of each travelling beam 2.
  • the punch 16 may also during the operation of the crane rest upon the abutment plate 15 if by corresponding adjustment of the control device 21 care is taken that the conduits l9 and 20 are connected to each other. in other words. when the chambers in cylinder 17 above and below the piston communicate with each other.
  • the provision of the pressure storage device 22 has the advantage that also in case of a power failure the fluid pressure required for pressing the plunger 16 against the abutment plate 15 is available. By means of the pump 23 leakage losses will be avoided. By means of this pump it is also possible. if necessary. to increase the fluid pressure.
  • the main compensating rockers 26 have lever arms of different lengths. More specifically. the ratio of the length of the lever arm which faces away from the central plane M to the length of the other lever arm is l 2.
  • the joints in which the corner points E are located have been designated with the reference numeral 27.
  • each of the main rockers 26 rests in a joint 28 on a carriage system which is equipped with compensating rockers 5, 7. 8, and with a compensating bogie 10 similar to the carriage system of FIGS. l and 2. and is consequently equipped with sixteen rollers or roller pairs ll.
  • each main compensating rocker 26 rests in a joint 29 on a compensating rocker 30 which forms a lever with arms of equal length and the ends of which rest in joints on shorter rockers 31 with arms of equal length.
  • the rockers 31 respectively rest on two compensating bogies 10.
  • the entire travelling system which is located below a corner point E has twentyfour serially arranged rollers or roller pairs 1].
  • pull rods 32 which engage the main rockers 26 at those ends thereof which face the central plane M. This is effected by means of oblong holes 33 in the lower ends of the pull rods 32. and by bolts 34 which are mounted on eyes 39 of the main compensating rockers 26 and engage the oblong holes 33.
  • the pull rods 32 are passed through openings in the travelling beams 2.
  • the upper ends of the pull rods 32 are pivotally connected to slide shoes 35 which are displaceably guided on the upper side of beam 2 in a direction parallel to the rail 1.
  • the slide shoes 35 are engaged by threaded spindles 36 which extend in the direction toward the central plane M and are surrounded by nuts 37 which are mounted in supports 38 on the travelling beam 2.
  • the nuts 37 are adapted to be ro tated by non-illustrated means so that the slide shoes 35 can be moved back and forth on the traveling beam 2.
  • the arrangement is such that in all positions of the shoes 35. the pull rods 32 extend from the bolts 34 with a smaller or greater inclination toward the top in the direction toward the central plane M.
  • the pull rods 32 occupy the central position which is illustrated on the right hand portion of FIG. 3 and in which the bolts 34 occupy a position in the central portion of the oblong holes 33. Accordingly, the main rockers 26 are permitted to tilt in the joints 27 in conformity with a corresponding unevenness in the rail route.
  • FIGS. 1 and 2 may be modified in a corresponding manner in such a way that the abutment plates 15 and the plungers 16 are provided on that side of the respective corner points E which face the central plane.
  • pull rods 32 from the bolts 34 in vertical direction through the beam 2 and that those ends of the pull rods which project beyond the beam 2 are by driving means. such as spindle-thread and nut or in a hydraulic manner. pulled in upward direction.
  • driving means such as spindle-thread and nut or in a hydraulic manner. pulled in upward direction.
