  • the present invention relates to an extensible movable bridge assembly, comprising several cooperating parts for performing, in a tunnel being built, operations such as the loading of mines, laying of reinforcing ribs and nets and the like.
  • the document FR-A-2 266 656 discloses an extensible movable bridge assembly having substantially the features of the pre-characterizing part of the main claim.
  • the aim of the present invention is to provide such an extensible movable bridge assembly which can be quickly and easily moved and installed.
  • a main object of the invention is to provide such an extensible movable bridge assembly which is very simple construction wise and very reliable in operation.
  • an extensible movable bridge assembly for use in building tunnels, having the features of the characterizing part of the main claim.
  • the extensible movable bridge assembly for making tunnels comprises a bridge frame, overally indicated at the reference number 1, which is affixed, by four brackets 2, to the chassis of a truck 3.
  • the bridge frame essentially comprises four section members HE, (4), extending horizontally and welded, at respective end portions thereof, to two section members "HE", of like cross-section, so as to define a rectangular construction.
  • stabilizing pistons 5 which are bolted to welded metal sheet box-like bodies 6.
  • a central body 7 made of welded sheet metal and which is arranged at the cabin of the truck.
  • This central body comprises four hinges for pivotably coupling raising arm members for raising a counter-platform which will be disclosed in a more detailed way hereinafter.
  • first access ladder 8 There are moreover provided a first access ladder 8, two guard walls 9 and 10 and a second ladder 11 for accessing the platform.
  • the top raising arm comprises four C-shape section members welded in pairs and mutually spaced by a L-shape section member lattice 13.
  • This top raising arm bears a hinge coupling portion for pivotably coupling the head portion of a raising piston 14 which is also articulated to the beams 4 of the frame.
  • the top arm is articulated, at one end thereof, to the central body and, at the other end thereof, to a central body 15 for supporting the above mentioned counter-platform.
  • the arm 12 As the arm 12 is arranged at a lowered position, it will rest, through the legs 16, on the frame 1.
  • a second raising arm 17 also made of four C-shape section members, welded in pairs and mutually spaced by a L-shape section member lattice 13'.
  • This second raising arm is pivoted, at one end thereof, to said central body 7 and, at the other end thereof, to the central body 15 of the counter-platform 18.
  • the above mentioned central body 15 is made of a welded and suitably ribbed metal sheet, and bears the pivot hinges for the raising arms 12 and 17.
  • the counter-platform in turn, comprises beams HE, (19), welded to the central body 15 and bearing horizontal rollers 20 on which a platform, overally indicated at 21, can slide.
  • the above platform in particular, is driven by a cylinder 23 which is respectively pivoted to said platform and counter-platform 18.
  • the platform 21 comprises moreover guard walls 24, a floor 25, made of HE and IPE beams, a sheet metal covering, as well as abutment rollers 26 for said beams 19, which rollers are provided for sliding said platform along said counter-platform 18.
  • a leg bearing frame 27 is moreover provided, made of square-cross-section tubular elements, in the inside of said frame 27 there being provided tracks 28, made of C-shape section members, and bearing a panel on which slide the wheels 29 of leg or wing members 30.
  • These legs are arranged under the mentioned floor 25 and are included in said frame 27 which, on vertical sides thereof, supports roller pairs 31 for restraining said legs.
  • Said legs in particular are provided with removable galleries 32 and comprise a respective piston 33 for driving said legs to perform extension and withdrawing movements.
  • a main feature of the invention is that in the subject extensible movable bridge assembly, the stabilizing elements, raising arms, platform and legs are driven by means of independent drives.
