Definitions

  • the invention relates to a mobile hammer crusher according to the preamble of claim 1.
  • Such hammer breakers are known in a wide variety of configurations.
  • the hammer weights are moved up on the mast so that they can then fall down to perform the desired destruction on the road surface. To achieve the corresponding destructive effect, a not too low head is required.
  • This drop height is determined by the mast height in the known hammer crushers. Since this must not be too small, the mast must be tiltable or pivotable so that its high height does not constitute a hindrance when driving over long distances.
  • the hammer weight is also relatively heavy, so that the hydraulic piston and cylinder device must perform an appropriate power to lift the weight. It has therefore already been proposed to run the rope over a pulley in order to provide a corresponding "translation".
  • a rope deflection pulley which is arranged there in a fixed manner and over which the rope starting from the hammer weight is guided, is located at the mast tip of the correspondingly tall mast.
  • the rope then runs over the pulley system with several loose rollers that are moved up and down by the piston and cylinder unit.
  • the rope guide pulley attached to the top of the mast forms the highest point, the height of which cannot be changed during operation.
  • the invention is based on the object of creating a mobile hammer crusher according to the preamble of claim 1, for which a sufficient head for the hammer weight is ensured during operation, but the mast is not so high that it is tilted, folded or pivoted for driving must become.
  • the mast is relatively short, that is to say of a low height.
  • the cable deflection roller which is arranged in a fixed position on the mast tip in the known hammer breakers, forms the loose roller of the pulley block, ie it can be moved up and down by the hydraulic piston and cylinder unit, that is to say also beyond the mast tip, so that the mast is shorter than the drop height of the hammer weight.
  • the device is characterized in that the cable deflection roller simultaneously forms the loose roller of the pulley block very compact and economical to manufacture.
  • the mast is so high that the rope deflection roller is in alignment with the mast tip, ie with the mast end, in the lower position of the hammer weight.
  • the hammer weight is moved as well, due to the pulley effect, by twice the distance that is determined by the piston and cylinder unit.
  • the rope deflection roller is higher than the mast tip, and the drop height of the weight is correspondingly greater.
  • the hammer weight can drop down to carry out the desired work.
  • the cable pulley moves down with it, half the distance that the hammer weight falls.
  • the cable pulley is again aligned with the mast tip, so that the overall height is low. In this position, the hammer crusher can then be moved over longer distances without an excessive mast height being an obstacle.
  • the hammer crusher is designed as protected in claim 2.
  • "Intermediate" between the mast and rope deflection roller is a carriage which can be moved up and down on rails or the like on the mast with the aid of the piston and cylinder unit.
  • the trolley is used to support the cable pulley and to attack the piston and cylinder unit. At the same time, it can be guided in a correspondingly stiff manner, taking into account the rough operation, in order to move the rope deflection roller beyond the mast tip and thus to raise the weight to the desired height.
  • only one rope pulley is present, which forms the rope deflection roller in the area of the mast tip, which at the same time forms the loose roller for forming the Pulley represents. This makes the device simple and compact.
  • the device can advantageously be designed as specified in claim 3.
  • the two rails, one rail for the hammer weight and one rail for the carriage, run parallel to each other on different levels.
  • the mobile hammer crusher shown in the drawing consists of a correspondingly constructed heavy vehicle 1 with wheels 2.
  • the actual hammer crusher is attached to the rear of the vehicle in this embodiment, and the rear wheels and the axle are correspondingly stable.
  • the actual hammer crusher attached to the vehicle 1 consists of a tower or mast 3, which is formed by cross members 16, a bracket 17, rails 6 and 15 and other stiffening elements.
  • the mast 3 is attached to the vehicle 1 in a suitable manner and is movable with it.
  • a hammer weight 4 can be moved up and down on the mast 3, heavy-duty rollers 5, which are mounted in the hammer weight 4, being guided in rails 6 of the mast.
  • a rope 7 engages the hammer weight 4, which is guided over a rope deflection roller 8 and extends to one of the crossbeams 16 (see FIG. 1) to which it is attached.
  • the cable pulley 8 is attached to a carriage 12 and rotatably mounted.
  • the carriage 12 is equipped with rollers 13 which are guided in rails 15.
  • the carriage 12 can be moved up and down with the cable deflection roller 8 in these rails 15.
  • the rails 15 run parallel to the rails 6 but in a different plane and at a smaller distance, as can be seen clearly when looking at FIG. 3.
  • the piston rod of a hydraulic piston and cylinder unit 14 acts on the carriage 12.
  • This hydraulic piston and cylinder unit 14 serves for the up and down movement of the carriage and thus the rope deflection roller 8 and, due to the rope guidance, finally also the hammer weight 4.
  • FIG. 6 shows a detail of the mounting of the heavy-duty rollers 5 for the hammer weight 4.
  • the shaft 21 of the heavy duty roller 5 is mounted in a bushing 25, which in turn is arranged in a rubber bushing 20.
  • a bushing 25 In the shaft 21 there is an elongated hole 21 through which a fastening pin 24 passes, which is fastened in the bush 25.
  • a spring 22 presses against the end face of the shaft 21 opposite the roller 5.
  • the roller 5 can be moved back and forth axially over the length of the elongated hole 23 and, due to the rubber bushing 20, can be tilted to a limited extent on all sides. In this way, movements of the hammer weight, in particular caused by an uneven floor, can be absorbed and compensated for.
  • the hammer crusher of the illustrated embodiment operates in such a way that the hammer weight is moved upward by appropriately loading the piston and cylinder unit 14 with pressure oil.
  • the piston rod extends from the cylinder, it moves the carriage 12 upwards, which is guided with its rollers 13 in the rails 15 of the mast 3.
  • the cable pulley 8 moves accordingly upwards beyond the mast tip. Since the rope 7 is attached to the cross member 16 at 10, the hammer weight 4 is pulled upward, specifically from the position shown in FIGS. 1 and 2 to the position shown in FIGS. 4 and 5. It is easy to see and see that the hammer weight 4 is moved twice the distance that the piston of the piston and cylinder unit is extended. This is due to the pulley effect, since the cable pulley 8 forms the loose role of a pulley at the same time.
  • roller 8 There is only one roller, namely the rope deflection roller 8, for forming the pulley and for deflecting the rope.
  • the device is thus compact and simple. Accordingly, it can be used economically.
