    专利说明:

    In particular, the present invention is intended for the movement of fire extinguishing machines, such as. B. those which use fluid jet emitting devices and which are in the form of "water cannons", ie comprising a tubular body in which an impeller is inserted and in the nozzles for emitting the fluid for use in fire fighting (usually water) or for Dust or odor removal can be used in the direction of the air flow, so that a jet is created that contains air and liquid.
    In firefighting operations in tunnels and underground transportation systems, manholes present a number of problems for conventional firefighting systems. In fact, the vast amount of smoke and soot that evolves undermines the firefighting procedures.
    All of this, combined with the high heat and reduced oxygen concentration, makes human intervention extremely dangerous.
    In order to solve this problem, self-propelled fire-extinguishing machines are known which are mounted on certain vehicles and can be remotely controlled in order to enable the operations and the extinguishing of the fire even under conditions under which human intervention is impossible or particularly dangerous.
    However, poor visibility, the often rough terrain and the possible presence of rails make the movement of these devices extremely complicated, with the added risk of damaging them, rendering them unusable and thus undermining the success of the operations.
    The possibility of mounting such machines on railway wagons, which then move along the railway line in order to bring the machine to the location of the fire, is known, as shown for example in patent EP 1391364.
    However, this solution also proves to be limited in terms of manageability and its complexity is intrinsic due to the need to provide movement of the wagon and the construction of a complex structure with many cumbersome parts.
    In this context, the technical problem on which the present invention is based is to provide a fluid jet emitting machine, in particular a fire extinguishing machine, which overcomes at least some of the above-mentioned disadvantages of the prior art.
    In particular, it is an object of the present invention to provide a fluid jet emitting machine, particularly a fire extinguishing machine, which is capable of moving quickly and safely along the rails without the need for complex structural procedures.
    The specified technical task and the stated objectives are essentially achieved by a fluid jet emitting machine, in particular a fire extinguishing machine having the technical features that are described in one or more of the appended claims.
    According to the present invention, a fluid jet emitting machine is shown, in particular a fire extinguishing machine, which includes a fluid jet emitting device, which includes at least one of the following: an odor removal solution, a dust removal solution, a flame reduction solution, a transport vehicle, lifting elements and a control device.
    The transport vehicle includes moving means, preferably equipped with tires, arranged in this way
    can be that they rest on rails of a track and a support frame on which the fluid jet emitting device is mounted.
    Each lifting element contains an actuator which is clamped onto the transport vehicle and at least one running wheel which is designed to engage in a rail of a track.
    The actuators are configured to move the respective wheels between an inoperative position in which the wheels are spaced from the respective rail and an operational position in which the wheels are arranged in contact with the respective rail.
    The control device is operatively associated with the actuators to activate the transition of the wheels from the non-operational position to the operational position, so that the wheels act as pressed against the respective rail during movement along a track and in this operational position and exercise a Force that reduces only part of the pressure exerted by the means of movement of the vehicle on the track, so that the means of movement is enabled to have a residual tensile force on the track.
    In the operating position, the wheels have the function of guiding the machine train on the track.
    Further properties and advantages of this invention will emerge more clearly from the following approximate and therefore non-restrictive description of a preferred but not exclusive embodiment of a fluid jet emitting machine, in particular a fire extinguishing machine, as shown in the accompanying drawings, in which:
    Figure 1 is a view of a fluid jet emitting machine with an exploded view of several components thereof.
    Figure 2 is a side view of a fluid jet emitting device in accordance with the present invention. Figure 3 is a schematic view of a road / rail conversion kit for vehicles in accordance with the present invention.
    A fluid jet emitting machine is indicated by the number 100 in Figures 1 and 2, and here below it is given as a fire extinguishing machine 100 as a non-limiting example. In particular, the fire extinguishing machine 100 includes a fluid jet emitting device 104, a transport vehicle 105, lifting members 102 and a control device 103.
    The fluid jet emitting device 104 includes a tubular body 106 extending between its air inlet mouth and its air outlet mouth, blowing means operatively connected to the tubular body for creating an air flow along a direction of propagation of the air from the inlet mouth to the outlet mouth, and a A plurality of nozzles 107 operatively connected to tubular body 106 for spraying fluid in the direction of the air flow. For example, the fluid used can consist of at least one of the following elements: an odor removal solution or a dust removal solution or a flame reduction solution.
    The transport vehicle 105 includes moving means 108, preferably moving means 108 equipped with tires, and a support frame 109 on which the fluid jet emitting device 104 is mounted.
    These moving means 108 can for example consist of caterpillars or wheels.
    In addition, the transport vehicle 106 can contain a control unit that is externally accessible to a “pedestrian” operator, or a radio control for remote control of the transport vehicle 105. Each lifting element 102 contains an actuator 102a that is reversible on the transport vehicle 105
    is clamped, and at least one wheel, which is designed to engage in a rail of a track. The actuators 102a are configured to move the respective wheels 102b between an inoperative position in which the wheels 102b exert no force against the track and an operational position in which the wheels 102b exert a force against the track so provided is that the pressure exerted by the moving means of the transport vehicle 105 on the track is partially reduced, this pressure being transmitted to the wheels 102b, and preferably a reduction in the pressure exerted in the range between 40% and 50%, preferably a reduction by 45 % is achieved, e.g. 2000 kg of the 3700 kg of the machine remain on the rail wheels.
    In other words, in the operating position the wheels 102b are pushed against the respective rail by the actuators 102a, as a result of which a force is exerted against the rails which causes the transport vehicle 105 to be partially lifted.
    The partial lifting creates a transfer of the pressure exerted by the moving means 108 on the tracks to the wheels 102b, which leads to an increase in their adhesion to the railway line, thereby reducing the risk of the transport vehicle 105 becoming detached from the line during the Movement of the fire extinguishing machine 100 moved away.
    However, this lifting movement is only partial in that the contact of the movement means 108 with the rails must be guaranteed at all times in order to ensure that they are able to move the fire extinguishing machine 100.
    The control device 103 is operatively associated with the actuators 102a in order to activate the transition of the wheels 102b from the non-operational position to the operational position such that the wheels 102b have the function of guiding the path during movement on the track, whereas the Means of movement have the function of moving the vehicle.
    In order to enable them to move along the railway line without having to use auxiliary traction means outside the traction means of the transport vehicle 106 of the fire extinguishing machine 100, the wheelbase of the movement means 108 must obviously have a length that is compatible with the track width of a rail on which the fire extinguishing machine 100 must be moved.
    The gauge is defined as the distance between the inside edges of the heads of the two rails of a track, measured at 14 mm below the tread; preferably reference is made to a track width equal to 1435 millimeters. In any case, it should be noted that the present invention can be adapted to any other track width value.
    The wheelbase of the moving means 108 is instead defined as the distance between the center planes of the moving means 108, which are arranged on opposite sides of the transport vehicle 105.
    In other words, the moving means 108 have a wheelbase compatible with a track gauge, and preferably the moving means 108 have respective bearing surfaces that are spaced apart so that they are simultaneously arranged in contact on respective rails of a track. In particular, the difference between the track width and the wheelbase of the moving means 108 is greater than 0 cm and less than twice the lateral dimension of a single moving means
    108 of the transport vehicle 105, so that it is always ensured that the movement means 108 are always all in contact with the rails at the same time.
    According to a preferred embodiment, which is shown in the attached FIGS. 1 and 2, the fire extinguishing machine 100 includes a clearing blade 110 at the front with respect to its direction of travel.
    The term “scraper blade” 110 is understood as a preferably flat and at least vertically movable plate (or with other degrees of movement in space) that has the function of clearing away all residues on the way of the fire extinguishing machine, so that such residues are prevented disrupt their movement.
    According to this embodiment, the fire extinguishing machine 100 includes a pair of lifting elements 102, which consist of a first lifting element 102 and a second lifting element 102, which are reversibly clamped on a rear portion of the fire extinguishing machine 100, and a third lifting element 102, which includes two running wheels 102b of each of which is reversibly clamped on a respective lateral end of the blade 110, and an actuator 102a that is reversibly clamped on the blade 110 and is configured to activate the movement of the blade 110 along a direction that is substantially perpendicular to the Level that carries the fire extinguishing machine 100 runs. As an alternative to the clearing shovel 110, the machine 100 can also contain other types of accessories at the front, which are not expressly specified here and which can move vertically or even with other degrees of movement in space.
    A road / rail conversion kit also constitutes an object of the present invention, and the schematic representation of a possible embodiment thereof appears in FIG.
    The kit 101 includes a plurality of lifting members 102 and a control device 103.
    Each lifting element 102 in turn contains an actuator 102a, which can be reversibly clamped onto a vehicle, and at least one running wheel 102b, which is designed to engage in a rail of a track.
    Each actuator is configured to move the at least one wheel 102b associated therewith (102a) between a non-operational position and an operational position.
    Preferably, each actuator 102a is connected at one end thereof to an impeller 102b. However, in the case where the vehicle to which the kit 101 is to be attached already has movable elements along a direction that is predominantly vertical with respect to the plane supporting the vehicle, it is also possible to place these elements between the actuator 102a and the wheel 102b so that the action of the actuator 102a acts on the movable element, which in its lowering / lifting movement also pulls the wheels 102b clamped therewith with it.
    In other words, it is possible to mount a plurality of wheels 102b on the same movable member of the vehicle on which the kit 101 is mounted, and then to install a single actuator 102a which by means of the movement of the movable member through the transition from the inoperative position to the operating position simultaneously all wheels 102b mounted on the same movable element are moved.
    The actuator can be implemented, for example, by means of a piston-telescopic body unit, in which the action of the piston leads to an extension / retraction of the telescopic body.
    The control device 103 is operatively associated with the actuators 102a to activate the transition of the wheels (102b) from the non-operational position to the operational position.
    It should be noted that the controller 103 is preferably of the type used by an operator
    is remotely controllable, for example by means of a radio control. Alternatively, the control device 103 contains control elements which are arranged directly on the machine 100 in order to control its functions. For example, the control device can be implemented by means of a control unit and a tank for a fluid in fluid communication with the actuator 102a of each lifting element 102.
    By operating the control unit, it is possible to pump a given amount of fluid from the tank to each actuator 102a, even independently, by mediating the transition from the non-operating position to the operating position or by recalling the same amount of fluid, thereby causing the actuator 102a is returned to the inoperative position.
    Advantageously, this control unit can be integrated into a control unit of the vehicle on which the kit 101 is mounted, so as to have a single control device which makes it possible to control both the vehicle and the kit 101.
    According to a possible embodiment, which is not shown in the accompanying figures, the kit 101 of the present invention contains two pairs of lifting elements 102.
    A first pair is configured to be clamped onto a front portion of a vehicle, preferably on opposite sides thereof, and spaced a distance equal to the gauge of the track on which the vehicle is to be moved, so that each engages in a respective rail of the railway line.
    A second pair is configured to be clamped onto a rear portion of a vehicle, preferably on opposite sides thereof and spaced a distance equal to that of a track gauge, so that each one engages a respective track of the railroad on which the vehicle on which the kit 101 is mounted needs to be moved.
    In particular, the kit 101 is configured so that, when in the inoperative position, it is attached to a vehicle which is arranged along a rail and has moving means in contact with the railroad tracks so that the lifting members 102 can be installed on the vehicle and at the same time intervene in the rail.
    The transition of the lifting elements 102 from the non-operating position to the operating position then takes place by means of the activation of the control device, as a result of which the vehicle is partially lifted.
    In other words, when the lifting members 102 pass from the inoperative position to the operative position, they cause a partial lifting of the vehicle on which the kit 101 was installed, thereby reducing the weight exerted by the means of movement of the vehicle which is instead applied to the Wheels 102b of the kit 101 is released.
    In this way, the existing coupling between the wheels 102b and the railroad tracks is reinforced, thereby ensuring greater stability during the movement of the vehicle.
    It should be noted, however, that the lifting movement of the vehicle reduces the pressure exerted by the vehicle on the railway line, but without causing it to become detached, so that the traction transmission means are in contact with the tracks.
    In fact, the kit 101 is not motorized, but it uses the normal movement mechanism of the vehicle on which it is installed to allow its movement.
    In other words, the kit 101 of the present invention is capable of converting the vehicle on which it is installed so that it is also able to move along a railway line and use the vehicle's normal traction mechanism, resulting in a simple, easily transportable and quickly installed solution.
    To facilitate installation of the kit 101 of the present invention, the kit 101 includes reversible fasteners configured to reversibly connect each lift member 102 to a respective portion of a vehicle.
    These reversible fastening means can for example contain screws, snap pins or bayonet couplings.
    A method for road / rail conversion of a vehicle is also an object of the present invention, the method including a step for arranging a fluid jet emitting machine according to the description given above over a railway line.
    The control device 103 is then actuated to activate the transition of the wheels 102b from the non-operating position to the operating position and to generate, by means of the wheels 102b, a thrust which causes a partial reduction in the pressure exerted by the moving means 108 on the track, this pressure being transmitted to the wheels 102b.
    In the case in which the kit 101 is not yet installed on the vehicle or is not part of the vehicle, a retrofitting process can be carried out which makes it possible to use a normal vehicle for the. To adapt rail transport by a step for the installation of a kit 101 on a vehicle, which is arranged along a track, the lifting elements 102 being clamped to the vehicle and the wheels 102b engaging the track.
    Advantageously, the kit 101 for rail transport of vehicles according to the present invention enables any vehicle, machine or other equipment to be modified so that it is also able to move along a rail.
    This conversion proves to be particularly simple and quick due to the simplicity of the use of the lifting elements 102.
    Advantageously, the fire extinguishing machine 100 of the present invention is able to move on roads and along railroads using its normal traction mechanism while ensuring the maneuverability of the vehicle and reducing the risk of the vehicle drifting off the road due to its partial lifting. to reduce to a minimum and even to
    eliminate, which makes it possible to ensure optimal adhesion of the wheels 102b to the railway line.
