Definitions

  • the present invention refers to an operating tool to be used in tunnel-making operations.
  • the present invention refers to a multifunction tool, equipped both with operating excavation abilities and gripping and/or supporting abilities.
  • tunnel-making works envisage specific operating stages. Reporting a full treatment of excavation and making techniques is not deemed necessary, as those are absolutely standardized, well-known to those skilled in the art and commonly used.
  • the making of a tunnel envisages the carrying out of an excavation performed with an operating tool, such as a demolition hammer, a ripper tooth or the like.
  • supporting structures are positioned to support the vault, for instance ribs placed in sequence, which in turn are then connected therebetween to form a single reinforcement for the lining of the tunnel.
  • a tunnel is an excavation, often carried out in rock, having a face of several tens of square meters; a rib is an arc-like metal structure, as wide as the entire vault of the tunnel and of a weight of several tons.
  • the tools at issue are all dimensioned with respect to the job to be carried out and, in order to be used, are mounted on the free end of the mechanical arm of an excavator.
  • object of the present invention is to solve the abovementioned problems, by proposing a multifunction tool as defined in independent claim 1.
  • a further object of the present invention is to provide a gripping device to be mounted on already existing tools, as defined in claim 16.
  • the present invention entails several evident advantages.
  • the present invention allows to reunite in a single device plural operating functions, in particular the excavating and gripping ones.
  • the gripping function could advantageously be exploited, both to pick and hoist the rib, and to carry an operator-carrying basket; all this without ever having to take apart the excavation tool.
  • the present invention allows to make use of the same advantages, though having traditional tools (hammers or hooks).
  • an attachment according to the present invention is prearranged to be fixed to a standard tool, with the consequence of making it immediately multifunction.
  • FIG. 1A to 1D illustrate the main steps during the excavation of a tunnel, carried out with the use of known tools
  • Figures 2A and 2B are views of a first embodiment of a tool according to the present invention.

  • the procedure envisages the positioning of a rib to support the vault of the tunnel that is being excavated.
  • the rib prearranged on the ground, has to be hoisted and correctly positioned.
  • This hoisting step is usually carried out with a specific tool, a gripper, as illustrated in Figure 1C.
  • a gripper has to be mounted on the free end of the mechanical arm of an excavator. Therefore, either a second excavator (or self-moving crane arm) is available, or it will be necessary to take apart the demolition hammer and mount the gripper in order to hoist the rib.
