Definitions
- the present invention relates to an apparatus for assembling reinforcement or supporting ribs in a tunnel being built.
- tunnel supporting ribs conventionally comprise curved element, made of a metal material, which are used for lining the walls of the tunnel being made.
- the mentioned reinforcement ribs comprise either one or two iron or section members.
- the reinforcement ribs made of a single piece are called simple reinforcement ribs, whereas the ribs comprising two iron or section members are conventionally called double reinforcement ribs.
- the reinforcement ribs are conventionally installed by means of raising arms which engage the ribs at a middle portion thereof and raise them so as to be properly located by the operators.
- the aim of the present invention is that of allowing the reinforcement ribs, pre-assembled on the ground, to be installed in a tunnel being built in a very quick and safe manner, and this by specifically designing a rib handling apparatus allowing the reinforcement rib to self-balance, as it is raised and further allowing the raised reinforcement rib to be automatically arranged in its proper position in which it can also be turned rightwardly and leftwardly.
- the two reinforcement rib locking pistons operate to:
- the spherical or ball articulation allows, moreover, the gripping fork to properly grip or engage the reinforcement rib, pre-assembled on the ground, independently from the position of the operating apparatus and the slant of the reinforcement rib, with respect to the ground surface.
- a reinforcement rib laying apparatus for tunnels and the like, characterized in that said apparatus essentially comprises a support member thereon there are pivoted an operating arm and a raising piston.
- the arm is specifically designed for raising a reinforcement rib gripping fork member, through a male ball support provided on the arm, and a female ball support provided on the reinforcement rib laying fork.
- the reinforcement rib laying fork apparatus including a rib gripping arm and related support, which can be used for installing tunnel reinforcement ribs assembled on the ground, in a tunnel being built, essentially comprises a box-like construction, of welded sheet metal, the so-called body, generally indicated at the reference number 1, which supports, on its right and left sides, two short teeth 2 and, at its central portion, four long teeth 3.
- two pistons 4 which are specifically designed to lock the simple reinforcement rib 5 or the double reinforcement rib 6 by means of a stop member 7, to be engaged with the reinforcement ribs by means of a semi-spherical articulation 8.
- the base member 12, driven by the small piston 13 bolted to the body 1, is mounted, as shown in Figure 7, in the case of a simple reinforcement rib and as shown in Figure 6 in the case of a double rib.
- a rod 14 which supports a balancing or equalizing assembly 15.
- the body 1 moreover supports, on its central portion, a female ball 16, comprises two mutually welded portions.
- the arm 17 comprises a cylinder 18 ending with a ball 19, nested within the female ball 16.
- This arm is raised by a piston 20.
- the support 21, anchored to the operating machine arm, is articulated, through a hinge assembly 22, to the arm 17 and, by a further hinge 23, to the piston 20.
- a shim or spacing element 24 can be interposed between the teeth 2 and 3 and the body 1, so as to increase the distance or inter-axis between the teeth to raise reinforcement ribs of larger or smaller width.
