Definitions

  • the present application relates to a building site machine.
  • building site machines which are substantially constituted by a tracked power chassis which is moved by means of a combustion engine located at its rear.
  • a building site machine is a boring machine, to which at least one drill rod or boom is articulated in front of the power chassis and has at one end a tool, such as for example an auger, which is adapted to perforate the terrain.
  • Such machines comprise a hydraulic system that can absorb at least double the available power supplied by the combustion engine, thus necessitating an electronic system to continuously manage the absorption of power so as to not exceed the available power.
  • the aim of the present invention is therefore to solve the above mentioned technical problems, eliminating the drawbacks in the cited known art and hence devising a building site machine that makes it possible to contain fuel consumption and reduce harmful emissions into the atmosphere.
  • an object of the invention is to provide a building site machine that can be used at any time of the day or night without disturbing people.
  • Another object of the invention is to obtain a building site machine that is structurally simple, that can be provided rapidly and simply, that can be made at low cost and that can be provided using the usual conventional machines and plants.
  • a building site machine comprising a tracked power chassis moved by means of a combustion engine, characterized in that said combustion engine is connected, by means of a clutch assembly, to a removable enclosure for containing an electric motor and for supporting a hydraulic pump assembly, said power chassis being provided with a container for at least one removable battery pack.
  • the reference numeral 1 generally designates a building site machine, for example a boring machine, a crane, a concrete pumping machine.
  • a boring machine is illustrated, of the type comprising a tracked power chassis 2, in front of which is articulated, by means of adapted and conventional devices that use struts 4, at least one boom 3 provided with adapted transmission pulleys 5 for cables 6 which are connected to a rotating head 7 associated with a drill rod 8 with one end of which a tool can in turn be associated, such as for example an auger 9, adapted to perforate the terrain 10.
  • a body 11 which accommodates a combustion engine 12, for example a diesel engine.
  • the combustion engine 12 is connected at the rear, by means of a clutch assembly 13, to an enclosure 14, shaped substantially like a parallelepiped and internally hollow and removable, for containing an electric motor 112 which is connected, by means of first cables 15, to an adapted inverter 16 and, by means of adapted second cables which are accommodated in protected conduits 17, to at least one removable battery pack 18.
  • the clutch assembly 13 comprises the usual mechanisms, such as the hydraulic actuation system 19, the clutch disc 20, the thrust bearing cylinder 21 for actuating the clutch by means of the hydraulic actuation system 19, the flywheel housing 22.
  • the enclosure 14 is advantageously connected, at the front end, to the flywheel housing 22 and, at the rear, to a coupling flange 23 for a hydraulic pump assembly 24 or for a device for coupling to hydraulic pumps.
  • the power chassis 2 furthermore has, above the body 11, a container 25 provided with a cover 26 and adapted to accommodate inside it at least one removable battery pack 18.
  • Adapted dividers 29 are mounted on the cover 26 or on the container 25 and generate a path 30 for the conditioning air which is obtained by means of a conditioning unit 31 and a fan 32, which are arranged in the container 25.
  • the machine comprises conventional electronic systems that are adapted to take account of the availability of power both from the combustion engine 12 (for example a diesel engine), and from the electric motor 112 and from the state of charging of the battery.
  • the combustion engine 12 for example a diesel engine
  • the machine therefore comprises in general a control system that has to manage the control unit present in the combustion engine 12, the clutch between the combustion engine 12 and the electric motor 112, the electric motor 112 with inverter, and the battery assembly.
  • the machine thus makes it possible to contain consumption and reduce harmful emissions into the atmosphere, including CO 2 , given that the combination of the combustion engine with the electric motor makes it possible to use, in the absence of an electric motor, a combustion engine with reduced power. Furthermore, the building site machine can be used at any time of the day and of the night by means of using only the electric motor, thus without disturbing people living nearby, and therefore without requiring any prior authorization from the respective authorities.
  • the easy access to the battery pack makes it possible to replace it rapidly, as needed, with another, charged battery pack. If maintenance needs to be carried out on the electric motor, the motor can be removed while at the same time making it possible, by virtue of the possibility of using the connecting shaft 27 between the combustion engine and the pump assembly, to continue to use the building site machine powered only by the combustion engine.
  • the electric motor can also be used in combination with the combustion engine, so that, for the same power dispensed, a combustion engine with reduced power, and therefore of lower cost, can be installed.
