Definitions

  • each support location of the rigid support frame of the crane as broad as possible by providing a number of balance supports and a multiplicity of travelling wheels to distribute the weight of the crane over a broad area of the quay. If a plurality of such balance supports are provided then considerable problems arise since it is not readily possible to avoid by means of such support locations lateral forces within the support frame owing to the prevailing moments caused by the uneven cause of the rails.
  • a quay surface bearing upon a number of piles constitutes a continuous beam which is loaded by one or a number of load pairs. These pairs of loads result from the support locations of the crane frame along a rail.
  • driven piles located at a spacing of about 3 /2 to 5 /2 meters viewed in the lengthwise direction of the rails.
  • cast tubular piles having a spacing up to 6 meters.
  • ship cranes are employed which have a support width in the lengthwise direction of the rails amounting to 9 to 14 meters.
  • Another and more specific object of the present invention relates to a new and improved construction of crane framework by means of which the aforementioned difficulties can be overcome so that also modern heavy cranes can be employed for quay installations and in particular for old quay installations.
  • the inventive crane framework of this development is manifested by the features that a number of frame struts are assembled together to form articulated supports intended to travel upon rails.
  • a plurality of rigid strut structures are constructed as articulated supports and bear through the agency of travelling wheels upon the rails.
  • Each articulated support can be then equipped with two support locations for the travelling rails viewed in the lengthwise direction of the rails. The weight of the crane and also the additional loads, for instance caused by wind, are nowtaken-up by a number of support locations. Each support location must therefore bear less load.
  • a crane framework 1 is constructed as a trussing or skeleton structure and can travel upon rails 2.
  • the illustrated crane framework 1 is depicted as if viewed from the side of the water, so that only one rail 2 is visible in the drawing.
  • Framework 1 is placed upon the rails 2 through the agency of the wheel supports-or carriages 3, 4, 5 and 6. These wheel supports 3 6 carry travellihg wheels 25.
  • the rails 2 are mounted upon a quay surface or cover 7 which issupported by piles 8. In the case of existing quay installations, the spacing 9 of the piles 8 from one another amounts to about 3.5 6 meters.
  • the frame struts or trusses l0, l1 and 12 form a hinged or articulated support arrangement 13 and the frame struts 14, 15 and 16 form a hinged or articulated support arrangement 17.
  • the lower struts 12 and 16 situated at the base at the region of the wheel carriages 3 6, in the illustrated exemplary embodiment, are arranged at least approximately horizontally extend longitudinally and serially along the rail 2, and in conjunction with two respective upwardly directed struts I0 and 11 and 14 and 15 are assembled together into the aforementioned articulated support arrangement 13 and 17.
  • These articulated supports or support arrangements l3 and 17 are pivotably mounted at hinge joints 18 and 19 essentially in the same horizontal plane.
  • the wheel carriages 4 and are disposed directly adjacent to one another, as is also the case for both of the travelling wheels 25 of each of the wheel carriages 3 and 6 respectively.
  • the adjacent base corners of the articulated supports 13 and 17 are spaced from each other by less than 1 meter.
  • the adjacent corners of the articulated supports 13 and 17 are interconnected with one another by means of a sliding joint or hinge 21.
  • Sliding joint 21 provides an articulated connection of both units 13 and 17 with one another and permits displacement of both of these units 13 and 17 towards and away from one another.
  • the hinge or articulation joints l8 and 19 are arranged over the associated bases defined by the struts l2 and 16 in such a manner that they are located at a spacing from the respective wheel carriages 3 and 6, as shown. This distance or spacing 20 amounts to about one-third of the length of the associated base struts 12 and l6.forming the respective base of the articulated supports 13 and 17. If there is then considered the wheel carriages 4 and 5 as a common support location, then each of the now available three support locations 3, 4 and 5, 6 takes-up a respective one-third of the vertical load. Hence, if for instance 102 tons act upon the rails 2, then there are supported 34 tons at the wheel support 3, likewise 34 tons at the wheel support 6, and the wheel support 4 takes-up 17 tons and the wheel support 5 likewise takes-up l7 tons.
  • the articulated supports 13 and 17 are designed as triangular guides and the travelling wheels of the wheel carriages 3 6 are located at the base corners of such triangular guides.
  • the wheel carriages 4 and 5 it would also be possible to place the wheel carriages 4 and 5 further from one another, for instance at a spacing in the order of 3 4 meters.
  • the spacing of both wheel carriages or supports 3 and 6 from one another can therefore be subdivided into three equal sections, so that also the wheel carriages 4 and 5 have the same spacing from one another as the wheel carriages 3 and 4 from one another and the wheel carriages 5 and 6 from one another.
  • the crane framework will be supported at four locations at the rails 2.
  • the spacing of the wheel supports 3 and 4 from one another so as to be at least approximately equal to the spacing 9 of the piles 8 then illustrated exemplary embodiment is more advantageous.
  • the rigidity or stiffness of the planes or the framework 1 disposed transverse to the rails 2 is not impaired by the articulation hinge joints 18 and 19. Viewed statically, everything remains the same as previously; this is also true for the entire framework.
  • the illustrated construction of the framework in other words the illustrated plane, can be provided at the front (at the side of the water as explained) and at the rear, or only at the front or only at the rear, depending upon the requirements imposed by the understructure of the quay installation.
  • the locations 18 and 19 instead of being designed as articulation joints, could also be constructed as standard connection or joint locations which areelastically deformable within the permissible stresses such that there occurs the same effect as for the mechanical constructed articulation or hinge joint.
  • Such type constructed connection or joint location 18 and 19 would then merely constitute a mathematical articulation or hinge.
  • a prior art construction of a rigid crane framework can not, for the purpose of distributing the vertical load, be supported at three wheel carriages or supports arranged in a row, since such rigid framework at three supports is incapable of accommodating an uneven rail.
  • Such known rigid framework for instance with the corner points l8, l9, 6 and 3, can be modified by cutting at the base in accordance with the inventive construction and providing the one beam portion 13 with the wheel carriage 4 and the other beam portion 17 with the wheel carriage 5. Then the location 18 and 19 would be constructed in such a manner that both beam portions 13 and 17 could move relative to one another. There would be installed between the beam portions 13 and 14 at the locations 4, 5, the slidingjoint 21.
  • a framework for a travelling ship crane on a rail comprising a pair of articulated support units, each constructed of struts rigidly joined in a triangular configuration to form a horizontal base and an upward extending apex,
  • hinge means at the apex of each articulated support unit for supporting the crane
  • sliding joint means interconnecting the adjacent base corners of the articulated support units
