Definitions

  • This invention relates to a paving machine for laying concrete and pulverulant materials such as asphalt on substrates such as road foundations or the ground.
  • the present invention relates to a screed plate finisher for use in conjunction with a paving machine.
  • Paving machines may be self propelled or constitute an accessory constructed for mounting on a vehicle.
  • Self propelled paving machines normally employ a hopper for carrying hot asphalt for distribution using augers over an area to be paved.
  • a screed plate serves to strike-off and level-off deposited asphalt prior to compaction of the so laid asphalt by, for example, tamping or rolling.
  • a so called gulley - two or more screed plates may be used and, by adjusting the screed plate relative to a substrate foundation the thickness of asphalt laid may be varied in a direction transverse to the direction of laying.
  • an extensible screed plate finisher for concrete or bituminous paving materials comprising a main plate fixed on support arms of the finisher, and at least one extra plate which is disposed behind the main plate in the direction of operation and which extends approximately over half the length of the main plate and which is connected to the main plate by means of guides and is laterally extensible by means of a displacement drive, and wherein the main plate carries a guide tube for receiving guide means connected to the extra plate, two guide elements are provided in spaced superposed relationship at the outer rear end of the main plate, and a rail fixed on the extra plate is guided between said guide elements.
  • the guide means used in the Vogele finisher are constructed in the form of a telescopic tube and the guide elements are rollers disposed on eccentrics.
  • a main screed plate assembly is in two halves only one of which, the left hand half, is shown in Figure 1.
  • the main screed assembly is supported between two end plates, 1, 2 which are held spaced apart and parallel to each other by a tube 3 of rectangular section and by a structure comprising a pair of rectangular section rails 4, 5 and a tube of circular section 6, which is the guide tube for the extension plate and forms the outermost of a set of three telescopic tubes.
  • a main screed plate itself is designated 7 in Figure 2.
  • An extension screed plate 8 which is also to be seen in Figure 2, is likewise supported between two end plates 9, 10 spaced apart by a tube 11 of rectangular section carrying a rail 12.
  • the end plate 9 which is disposed outboard of the assembly carries an innermost tube 13 of one of the three telescopic tubes working within the guide tube 6.
  • the extension screed plate 8 is extended or retracted by operation of a hydraulic jack 14 operating between the outer end ylate 9 of the extension screed plate assembly and the inner plate 2 of the assembly carrying one half of the main screed plate.
  • the end and inner plate 10 of the extension screed plate assembly carries a boss 15 with a central opening 16 affording clearance for the outside of the guide tube 6.
  • the boss 15 supports a pair of pressure pads 17, 18, one of which 17 engages a machined under surface of the rail 4 and the other of which 18 engages a machined upper surface of the rail 5.
  • the surfaces of these rails which are not engaged by the pressure pads do not need to be machined accurately parallel or flat.
  • the action of the pressure pads on these rails supports the weight of the extension screed plate assembly when it is clear of the ground.
  • the rails 4 and 5 must be rigid enough for this purpose and they may themselves be supported on tubes or struts between the end plates, or, as indicated in Figure 2, rebated slightly into grooves milled in the sides of the guide tube 6.
  • the rectangular tube 11 of the extension tube assembly carries a rail 12 which is machined on its upper surface for engagement with a pressure pad 19, shown in more detail in Figure 2.
  • the pressure pad 19 is shown in greater detail in Figure 3 and comprises a block 20 of low friction material supported by a pair of adjusting screws 21, 22.
  • the pressure of the block 20 on the rail 12 supports the reaction of the ground against the extension screed plate 8 less the weight of the extension itself and, as wear takes place, the screws can be advanced to compensate. This adjustment is well clear of the internal mechanism of the extension support assembly and readily accessible for adjustment by an operator. Further, machined bearing surface of the rail 12 itself is readily accessible for cleaning.
  • the extension screed plate is supported by end plates 9 and 10 as well as guide tube 13 which slides telescopically within guide tube 6 which serves as a bridge between end plates 1 and 2.
  • the guide tube 6 is constructed in the same manner as described with reference to Figures 1 and 2.
  • the embodiment of Figures 4 and 5 differs from that of Figures 1 and 2 in the arrangement of guide rails and pressure pads.
  • the guide rails are designated 4A and 5A respectively with associated pressure pads 4B and 5B respectively.
  • Each of the guide rails 4A and 5A are mounted in parallel between end plates 9 and 10 and the pressure pads 5A/5B are constructed as shown in Figure 3.
  • Rams 26/26A are shown in figure to be mounted laterally of each other and laterally of the guide tube 6, if desired, they may be mounted vertically above each other. Further, an additional tubular support 11 may be used to maintain and reinforce the spaced relationship of end plates 1 and 2 and 9 and 10 respectively.
  • the pressure pads 4B and 5B for guide rails 4A and 5A are each carried on the end plates 1 and 10 as shown so as to permit movement of the guide rails 4A and 5A in the direction of arrows "x" and "y" in Figure 4 .
