Definitions

  • the present invention relates to a mobile crane powered by one or more diesel engines and intended to operate in regions where the ambient temperature can drop below -30 ° C, to reach temperatures of the order of -40 ° C at -50 ° C for example.
  • said hot air generator comprises an air inlet connected to an outlet socket of said diesel engine on the one hand and to the suction inlet of the centrifugal fan on the other hand, as well as a tube-shaped casing containing electrical resistances, and whose upstream air inlet is connected to the discharge outlet of the centrifugal fan, while its downstream air outlet is connected to an inlet socket said diesel engine.
  • FIG. 1 a mobile crane composed of a carrier 1 driven by a diesel engine 2, which also distinguishes the diesel tank 4 and starter batteries 3, and a crane part 5.
  • the crane part 5 can rotate around an axis 6 and is itself driven by another diesel engine 7 also equipped with starter batteries 8 and a diesel tank 9.
  • the batteries (3.8) and the tanks (4.9) are each placed in an enclosure which can be heated by electrical resistances, said enclosures not having been detailed in the figure.
  • each diesel engine (2.7) is permanently associated with a heating device (respectively 13 and 15) with circulation of hot air heated by electrical resistances, the hot air being sent inside. of each of the motors (2,7) and being recycled into the hot air generator, the latter being equipped with a centrifugal fan (respectively 16 and 17).
  • the carrier 1 is equipped with a socket 14 which can be supplied with electrical energy either by an external socket, such as a site service socket, or by a generator 12 on board the vehicle and operating for example using a small gasoline engine.
  • the socket 14 is associated with a conventional switch 11 which makes it possible, according to the chosen switching, to supply electrical energy either with the electrical resistances and fan intended for heating the motor 2 of the carrier and its accessories (3,4), or, by means of a rotary electrical collector 10 of conventional type, supplying electrical energy to the corresponding heating elements (8, 9, 15) of the engine 7 equipping the crane part 5.
  • the heating device shown diagrammatically in FIGS. 2 and 3 consists of a casing 16 in the form of an elongated tube of square section (the square or rectangular section having been found more advantageous than the circular section) and containing two heating resistors (17, 18) of three kilowatts each supplied with electrical energy by means of a terminal plate 19 which is also used for fixing said resistors to the casing 16.
  • the two resistors 17 and 18 are standard armored electrical resistors of wide distribution and are placed at right angles as shown in the drawing.
  • the casing 16 is provided with an upstream inlet orifice 20 connected to the discharge outlet of a turbine 21 constituted by a centrifugal fan driven by an electric motor 42 surrounded by an electric preheating resistor not shown.
  • a centrifugal fan is essential for the implementation of the invention, because only this type of fan allows, without costly artifices, the use of an electric drive motor 42 which does not not found in the jet of hot air which, as will be seen below, allows operation of the assembly in a closed circuit.
  • the downstream outlet orifice 41 of the casing is connected, via a flexible pipe 22, to an inlet orifice 23 in the motor 2, normally closed by a plug 24 held attached to the motor by a chain 25, the seal being made by a seal 26.
  • the suction inlet of the centrifugal fan 21 is connected, via a flexible pipe 27, to a socket 28 of output of motor 2, also normally closed by a plug 29 retained by a chain 30.
  • the assembly constituted by the casing 16 and the turbine 21 is fixed to the motor 2 by means of supports 31. Furthermore, the installation can optionally be equipped with relay thermocouples (32, 33) placed respectively at the outlet 41 of the casing 16 and at the air outlet 28 of the engine 2, and being able for example to allow an automatic control of the heating device, the thermocouples 32 and 33 measuring the temperature of the heating air at the inlet and at the outlet of the engine and acting for example on electrical contactors controlling the starting or stopping of reheating.
  • relay thermocouples 32, 33
  • the inlet 23 and outlet 28 ports are chosen by the user so as to allow circulation of hot air in the engine. Their choice is simple to make depending on the engine used, and Figures 4 and 5 only give an indication of a non-limiting example which is not in itself part of the invention.
  • the inlet 23 is taken on the line 34 comprising the oil filling inlet 35 and the outlet 36 of the oil vapors to the breather.
  • the air outlet 28 is taken on a manhole 37 normally fitted to a shaft socket 38 closed by a cover 39.
  • Figure 6 shows the terminal plate 19 seen in the direction f of Figure 2, the diagram shown, very conventional, corresponding to the parallel supply of the two resistors.
