Definitions

  • the invention relates to a pin mounting arrangement including : a mining vehicle having a frame : and at least one mounting unit , the mounting unit comprising : a first mounting plate having a semi-circular recess and being mounted against the frame or part of it ; and a second mounting plate having a semi-circular recess and being mounted against the first mounting plate , the two semi-circular recesses facing each other and forming a circular opening for the pin .
  • the invention also relates to a mining vehicle .
  • This invention relates firstly to mounting of hydraulic cylinders , for example hydraulic steering cylinders to underground vehicles (mining vehicles ) , such as articulated underground loaders or trucks .
  • Underground vehicles are mainly used in mining industry .
  • the pin mounting arrangement can also be used for mounting of a j oint pin of an articulated underground vehicle or for mounting a swing lever of an articulated underground vehicle or for pivot pin mounting of an oscillating axle assembly .
  • mainly the mounting of a hydraulic cylinder is discussed .
  • the steering cylinder is typically mounted to a corner box or the hydraulic tank of the vehicle frame with two mounting plates .
  • Both mounting plates have a semi-circular recess facing against each other and thus forming a circular hole for the fastening pin of the cylinder .
  • Similar arrangement is needed for fastening the other end of the fastening pin of the cylinder .
  • the first mounting plate is welded to the frame (usually to a corner box or hydraulic tank) of the vehicle and the second mounting plate is fastened to the first mounting plate with mounting bolts .
  • Both mounting plates are machined as a pair .
  • both mounting plates must be replaced at the same time .
  • the problem with the current construction is that it is not possible to remove the used mounting plates without machining, because the first mounting plate has been welded to the vehicle frame . The machining is time consuming and laborious .
  • An obj ect of the invention is to provide a new pin mounting arrangement so that the problem existing in the current mountings can be solved .
  • the arrangement of the present invention is characterized in that the frame or a part fixed to the frame and the first and second mounting plates have matching holes for mounting bolts with which they are detachably mounted together .
  • the pin is the fastening pin of a hydraulic cylinder, for example a steering cylinder of an articulated underground loader .
  • the part fixed to the frame is a corner plate welded to the frame or to a corner box or a hydraulic tank of the frame .
  • the corner plate and the first mounting plate have through holes without internal threads
  • the second mounting plate has holes with internal threads matching with the external threads of the mounting bolts , and that the mounting bolts are mounted from outside the corner plate through the corner plate and the first mounting plate to the holes of the second mounting plate and tightened .
  • the first mounting plate and the second mounting plate both have through holes without internal threads
  • the frame part has holes with internal threads matching with the external threads of the mounting bolts , and that the mounting bolts are mounted from outside the second mounting plate through the holes of the second and the first mounting plates to the holes of the frame part and tightened .
  • a recess has been made , the recess matching the size and shape of the first mounting plate .
  • the pin is a j oint pin of an articulated underground vehicle .
  • the pin is a fastening pin of a swing lever of an articulated underground vehicle .
  • Another obj ect of the invention is to provide a new mining vehicle without the problems related to the existing mining vehicles .
  • This obj ection is achieved by a mining vehicle as defined in claims 9- 15 .
  • One advantage of the invention is that the mounting plates can be replaced without machining, which improves the serviceability of the underground vehicle . In case of stuck mounting bolts , it is easier to cut off the mounting bolts from the outside of the corner box or the hydraulic tank .

  • Figure 6 is a perspective view of the arrangement of Figure 6 in an opened position .
  • Hydraulic cylinder 1 can be used in mining vehicles .
  • the vehicle itself has not been shown, but it can be for example a known articulated underground loader or truck, in which the hydraulic cylinder 1 can be used as a steering cylinder .
  • FIG. 2 To the vehicle frame 2 a corner plate 3 has been fixed for example by welding .
  • the frame 2 or the part of it to which the hydraulic cylinder 1 has been mounted can be for example a corner box or hydraulic tank of the vehicle .
  • a first mounting plate 4 and a second mounting plate 5 for mounting the fastening pin 7 of the hydraulic cylinder 1 have been mounted to the corner plate 3 with mounting bolts 6 .
  • FIG. 2 there are two essentially identical mounting units 10 , in this case an upper and a lower unit both including one first mounting plate 4 and one second mounting plate 5 .
  • the mounting of the fastening pin 7 of hydraulic cylinder 1 thus needs two first mounting plates 4 and two second mounting plates 5 altogether .
  • the mounting arrangement according to the invention shall be explained more in detail in connection with the following Figures .
  • FIG 3 shows the mounting arrangement of the invention, i . e . the mounting plates 4 , 5 and the mounting bolts 6 in an exploded view .
  • the corner plate 3 has holes , through which the mounting bolts are pushed towards the mounting plates 4 , 5 .
  • the first mounting plate 4 has also through holes without internal threads
  • the second mounting plate 5 has holes with internal threads .
  • the mounting bolts 6 of course have external threads matching with the internal threads of the second mounting plate 5 .
  • Both mounting plates 4 , 5 have a semicircular recess facing against each other and thus forming together a circular hole for the fastening pin 7 of the cylinder .
  • both mounting plates 4 , 5 must be replaced at the same time .
  • the bolts 6 can be reached from outside the corner plate 3 , which makes them easier to remove .
  • Figures 5 and 6 show another embodiment of the present invention or part of it .
  • reference number 2 shows part of the frame of the vehicle .
  • first mounting plate 4 and the second mounting plate 5 both have a through hole without internal threads . Instead, the internal threads have been machined to the holes 8 of the frame part 2 . Hence , the mounting bolts 6 are mounted from the outside of the second mounting plate 5 towards the frame part and tightened to form a unit as shown in Figure
  • a recess 9 has been machined in the frame part 2 , the recess corresponding to the size and shape of the first mounting plate 4 , whereby the first mounting plate 4 can be guided and fitted snugly to the recess 9 .
  • the recess is of course not always necessary and the mounting bolts 6 may provide a sufficient strength of the j oint .
  • the recess 9 which provides at least a partial shapes-lock for the j oint, may reduce the forces to the mounting bolts 6 .
  • Shapes-lock recess or other form can be made in which ever side it is needed, but in Figs . 5 and 6 a situation has been shown which could be used for example with swing lever mounting .
