Definitions

  • a procedure for adjusting the inclination relative to the vertical direction and the direction of travel of a rail wheel of a crane is a procedure for adjusting the inclination relative to the vertical direction and the direction of travel of a rail wheel of a crane.
  • each end of the shaft of the rail wheel is provided with an eccentric bearing bush held by its outer surface in the frame of the end carriage.
  • eccentric bearing bush By turning the eccentric bearing bush, it is possible to change the direction of travel of the rail wheel and its inclination relative to the vertical direction. In the starting situation, both bearing bushes lie with their eccentricity in the same direction, generally straight upwards.
  • a new procedure for adjusting the direction of a rail wheel of a crane is presented as an invention.
  • the procedure of the invention for adjusting the direction of a rail wheel of a crane is characterized by what is presented in the characterization part of claim 1.
  • Other embodiments of the invention are characterized by the features presented in the other claims.
  • the eccentric bearing bush on one side of the wheel is used to adjust the direction of travel while the one on the other side is used to adjust the vertical direction of the wheel.
  • Fig. 1 presents three different views of a rail wheel 1.
  • the figure shows the eccentric bearing bushes 2a and 2b on either side of the rail wheel 1, which in the structure of the invention consist of journal boxes 3a and 3b and shields 4a and 4b having an eccentricity with respect to each other
  • Figures 3 and 4 present a diagrammatic illustration of the eccentric surfaces 9 forming part of the bearing bushes 2a and 2b.
  • the shields match the inside diameter of the journal boxes 3a and 3b and are attached to each other by means of bolts 5.
  • the eccentricity has to be so chosen that the necessary adjustments can be achieved with an angle of rotation below 20°.
  • Bearing surfaces 8a and 8b are provided at supporting plates 7a and 7b to bear the eccentric surfaces 9 of the bearing bushes 2a and 2b.
  • the bearing surfaces 8a and 8b are mounted to have the same eccentricity as the corresponding eccentric bearing bushes 2a and 2b.
  • the bearing surface 8a for the bearing bush 2a on one side of the wheel is made equally eccentric to the centre of shaft 6 as the bearing bush 2a.
  • the direction of eccentricity of the bearing surface 8a of the supporting plate 7a is selected e.g. on the basis of the desired directional effect. If the eccentricity of the bearing surface 8a is in the direction of the vertical axis and the bearing bush 2a is eccentrically installed so that it compensates the eccentricity of the bearing surface 8a (the journal box 3a lies on the centre line of the shaft), then the horizontal motion of the centre of the journal box 3a will be considerably larger than the vertical motion.
  • FIG. 1 also shows the shaft 6 by means of which the rail wheel 1 is mounted in the bearing bushes 2a and 2b, as well as the above-mentioned supporting plates 7a and 7b whose bearing surfaces 8a and 8b guide the bearing bushes 2a and 2b and which are mounted on the frame of the end carriage so that they have the same eccentricity in the same direction as the corresponding outer diameters of the bearing bushes 2a and 2b.
  • Supporting plate 7a has a horizontal eccentricity and supporting plate 7b on the opposite side a vertical eccentricity relative to the centre of shaft 6.
  • the end carriage steel structure is manufactured to as high a precision as possible so as to minimize the need for adjusting the direction of the rail wheels 1. Because of the precision requirement regarding the direction adjustment, there is generally always a need for adjusting the direction of the rail wheel.
  • the adjustment is performed as follows: The inclination relative to the vertical direction is adjusted by rotating bearing bush 2a, and the direction of travel is adjusted by turning bearing bush 2b. In the solution of the invention, bearing bush 2a is rotated if the centre of journal box 3a is to be moved in the vertical direction.
  • bearing bush 2b When the direction of travel of the rail wheel 1 is to be corrected, bearing bush 2b is rotated either clockwise or anticlockwise, depending on the direction of the desired correction. This produces a horizontal displacement of the centre of journal box 3b.
  • the bearing bushes 2a and 2b and supporting plates 7a and 7b are provided with markings indicating the position of the eccentric. When the adjustment is started, these markings must be aligned with each other. Thus, the markings allow the installer to see how much the bearing bushes 2a and 2b have been rotated during the adjustment.
  • FIGs in Fig. 2 illustrate the effect of the direction adjustment, diagram A showing a view from the side of supporting plate 7a and the corresponding bearing bush 2a and diagram B from the side of supporting plate 7b and bearing bush 2b.
  • diagram A showing a view from the side of supporting plate 7a and the corresponding bearing bush 2a and diagram B from the side of supporting plate 7b and bearing bush 2b.
  • the design of the eccentric bearing bush may be varied by placing the eccentric surface 9 either on the inside or outside of the bush, and the bush may be manufactured as a single part or as consisting of several parts.
  • the bearing surface 8a,8b guiding the bearing bush 2a,2b can be produced by casting or machining it in the framework or a separate part attached to it, and so on.
  • the solution of the invention can also be applied for the adjustment of fulcrum pins and the shafts of rope pulleys.
