Definitions

  • the present invention relates to an excavating assembly and an operating machine comprising this assembly.
  • the present invention relates to an assembly that comprises an excavating apparatus comprising an excavating tool, for example for forming trenches, or for removing layers of tarmac or the like.
  • circular milling cutters are known that are placed above the manhole and mill circularly with a rotary cutting motion around the manhole and with a depthwise traveling movement transversally to the operating surface until an annular groove has been dug that can remove the manhole.
  • circular milling cutters are always used with a rotary cutting motion around the center of the hole that is intended to be made, and with a depthwise traveling movement transversally to the operating surface.
  • CN104594170 discloses a device for repairing paving.
  • This device comprises a fixed part, a rotary part that is rotatably connected to the fixed part and rotates around the circumference of the fixed part.
  • the rotary part is a disk cutter that oscillates around a fulcrum of the fixed part and is therefore always inclined with respect to the paving.
  • the device for repairing the paving is mounted so as to be held in an operating position with respect to the fixed part.
  • the rotary part rotates about an axis of the fixed part, or well-head, and the disk-shaped tool of the cutter part cuts the tarmac of the paving.
  • This known device is only suitable for cutting along circular and converging paths, thus creating conical cuts.
  • This tool does not make it possible to mill a strip having a predefined width around the desired portion, for example the manhole, but only makes it possible to create a deep and inclined cut. Furthermore, this known device does not comprise a driven milling cutter, but requires a separate actuator and a complex transmission for transmitting the motion to the tool. Furthermore, this tool is permanently connected to the fixed structure, thereby preventing the use of the tool for other applications.
  • EP1048787 describes a method for repairing or replacing the road surface using a conical mill supported by a rotary arm such that it maintains its vertical axis.
  • This known device is also only suitable for cutting along circular paths and creating conical cuts.
  • This tool does not make it possible to mill a strip having a predefined width around the desired portion, for example the manhole, but only makes it possible to create a deep and inclined cut.

  • This device is made up of a centering support that is inserted into the frame of a manhole.
  • This centering device rotatably supports a frame that receives a tool that is powered by means of an external motor and a belt transmission.
  • This known device does not comprise a driven milling cutter, but requires a separate actuator and a complex transmission for transmitting the motion to the tool.
  • this tool is permanently connected to the fixed structure, thereby preventing the use of the tool for other applications, for example for milling along linear paths.
  • this device requires an operator for rotating the rotary support structure around the manhole.
  • the proposed solution makes it possible to use an excavating apparatus, which is used for excavating trenches or removing layers of the road surface, usually along rectilinear paths, and, using the same apparatus that is mounted in the assembly of the present invention, to obtain a cutting movement that is substantially parallel or tangential to the operating surface by rotating the cutting tool about its axis of rotation that is parallel to the operating surface, and a cutting path that travels in a circle around the manhole.

  • this adjustment could be carried out by means of a single depth adjustment device 24.
  • the position of the abutment sliding blocks 12, 14 with respect to the excavating tool 8 can be independently adjusted, and so the spacing between each sliding block and the excavating surface can be selected in an autonomous manner.
