    ROTATING CRANE BRIDGE
    DESCRIPTION
    OBJECT OF THE INVENTION
    The present invention falls within the technical field of crane bridges that comprise one or more substantially horizontal main beams, and refers in particular to a crane bridge equipped with a box of chains and a mobile lifting mechanism to extend the surface of work covered by the chain, which finds special application, although not limited to this field, inside small spaces, such as wind turbine gondolas.
    BACKGROUND OF THE INVENTION
    The bridge crane is a lifting device composed of a beam, single or double, that supports either on two raised rails on posts, or on the building's own components, and a lifting or crane mechanism, mounted on a carriage which moves along said beam, in what is called the rolling path. Unlike mobile cranes used in construction, crane bridges are generally used in fixed installations to mobilize high loads both horizontally and vertically within the facility itself.
    Within the fundamental parameters to be determined in a crane bridge, it is known as total light at the maximum horizontal distance between the supports of the beam, while the useful light is the maximum horizontal distance between the axis of the raceway closest to the support and the axis of the clamping element, in this case the chain and the crane hook, located on the beam.
    The carriages comprise safety elements intended to prevent their movement to the respective end ends of the beam, which generally consist of retaining arms that, as a stop, prevent their approach to said end and retain the carriage, and the lifting mechanism mounted on it, in a position far enough away from said endpoints. This position greatly reduces the useful working space of
    the chain, which is especially harmful in cranes bridges destined to work in

    small spaces with irregular environments, such as inside the wind turbine gondolas.
    DESCRIPTION OF THE INVENTION
    The object of the invention consists of a crane bridge with the ability to turn and displace certain elements, specifically the chain containing box and the lifting mechanism, which increases the useful working light of its chain by up to 20% with respect to conventional bridge-cranes, making it especially applicable in small spaces, although not limited to such spaces. A preferred embodiment of the crane bridge is designed to be permanently installed inside wind turbine gondolas, which in the cases of larger ones have approximate dimensions of 8 meters wide, 14 meters long and 8 meters high.
    The rotating crane bridge comprises a beam, preferably a double beam, fixed at their respective ends to a structure, by which they move a carriage longitudinally, a crane-type lifting mechanism linked superiorly to the carriage, and a chain box linked inferiorly to said carriage. carriage, in a position inferior to the beam and displaced with respect to a central longitudinal axis of the carriage and the lifting mechanism.
    In order to allow the chain, and the hook linked to said chain, to the respective end ends of the beam, thereby increasing its useful working space, first all the components of the lifting mechanism are arranged on a base or platform, which is rotatably movable on a rolling bearing defined in the car on which the lifting mechanism that moves longitudinally along the beam rests.
    Second, the chain box is laterally movable relative to the car. To this end, said chain box is inferiorly linked to the carriage by means of releasable joining means, said joining means being preferably a releasable arm, provided with fixing means that link the joining means with a fixing point defined in the carriage, which allows a longitudinal displacement of the chain box, until it is located to the right of the car, at which point the fixing means fix the position of the chain box with respect to the car.
    All the movements described above are capable of being automated and governed from an external control unit.

    PREFERRED EMBODIMENT OF THE INVENTION
    Next, a detailed explanation of an example of preferred embodiment of the object of the present invention is provided with the aid of the aforementioned figures.
    The rotating crane bridge described, shown in figures 1 and 2, is formed by a double beam (1), fixed at their respective ends to a structure, by which they move a carriage (2) longitudinally, a lifting mechanism ( 3) crane type linked superiorly to the carriage (2), and a chain box (4) inferiorly linked to said carriage (2). As can be seen in these figures, the chain box (4) is located in a position lower than the beam
    (I) and displaced with respect to a central longitudinal axis of the carriage (2) and the lifting mechanism (3).
    The chain box (4), shown in Figure 3, travels longitudinally along the lower end of the beam (1), by rolling first wheels (5) by lower skates of said beam (1), of which are suspended. Said chain box (4) comprises a housing (6) of essentially parallelepipedic geometry and hollow interior, intended to accommodate a chain (7) of the lifting mechanism (3), which is removed from said housing (6) through a opening (8) defined on an upper face.
    This box of chains (4) is linked to the carriage (2) through means of union (9), which in this preferred embodiment are a releasable arm, fixed at one of its ends to a glutton (10) defined in the surface of the housing (6) and linked at its other end to a fixing point (11) of the carriage (2), through fixing means (12), which in this case are a threaded spring positioner. The chain box (4) additionally comprises a plurality of handles (13) defined on the outer surface of the housing (6).
    The carriage (2), illustrated in Figure 4, moves longitudinally along the upper end of the beam (1), by rolling of second wheels (14) by upper heads of said beam (1), on which support Said carriage (2) comprises an essentially parallel and flat base (15), with a lower face to which the second wheels (14) and a motor (16) are linked, and an upper face from which the point of projecting is projected. fixation
    (II) of the joining means (9) of the chain box (4), and pivoting rings (17).

    An orifice (18) of essentially circular geometry, defined in the central part of the base (15), connects its upper and lower faces. A rolling bearing (19) made of teflon is fixed on the longitudinal edge of said hole (18).
    The lifting mechanism (3), as seen in Figure 5, first comprises a support (20) of geometry and dimensions essentially similar to those of the bearing (19) of the carriage (2), with which it is intended to be linked . Said support (20) also comprises an upper face, a lower face and a through central hole.
    From the upper face of the support (20) the lifting device is upper part, composed of a lifting motor (21) and a reel (22) on whose surface the chain (7) is wound. A plurality of handles (23), evenly distributed along the outer edge of said upper face, and pivoting rings (17) similar to those arranged on the upper face of the carriage (2) are also projected towards the upper part of the support (20). ). Also, a fixed arm (24) that laterally part of the support (20) limits the displacement of the lifting mechanism (3) and the carriage (2) to which it is linked along the raceway on the beam (1) to avoid impacts of the support (20) and its elements with the ends of said beam (1) and the structure on which it is supported, upon reaching the end of the road.
    The chain (7), comprises a first end linked to the reel (22) and a second free end to which a hook (25) is attached to link with the elements to be displaced by the lifting mechanism (3). Said chain (7) moves longitudinally in upward or downward movement through the space between the two bodies that constitute the double beam (1), depending on the orders sent by an external control device, not shown in the attached figures. As can be seen in said figures, the chain (7) has an eccentric arrangement with respect to the central longitudinal axis of the carriage (2) and the lifting mechanism (3).
    A flexible hose (26) of essentially cylindrical geometry and hollow interior contains and protects the wiring necessary for the operation of the crane bridge. Said hose (26) runs between the respective rings (17) of the carriage (2) and the lifting mechanism (3). It is also contemplated the incorporation of a plurality of sensors (27) arranged both in the carriage (2), as in the lifting mechanism (3) and in the chain box (4) that send information about the position of said elements to a sensor box (28) arranged at one of the end ends of the beam (1).
    Figures 6 and 7 show two views of the carriage (2) and the lifting mechanism (3) mounted on said carriage (2) arranged at the end of the raceway, near the end of the beam (1) in which the sensor box (28) is arranged. As can be seen in said figures, the useful overhang of the chain (7) is reduced by a distance marked in Figure 6 5 as "a", distance in which said chain (7) is not enough to transport any cargo.
    Figures 8 and 9 show two other views of the carriage (2) and the lifting mechanism (3) at the same end of the beam (1), in a position in which the useful overhang of the chain (7) is is reduced by a distance marked "b", which, as seen, is less than the distance "a" 10 above. The passage from one position to another therefore increases the overhang or useful working space of the chain (7), which beneficially results in the operation of the crane bridge.
    Said position change is due both to a lateral displacement of the chain box (4) and to a rotation of the lifting mechanism (3) with respect to the carriage (2). For the displacement of the chain box (4), the sequence of which is shown in Figure 10, firstly the fixing means (12) that fix the joining means (9) at the fixing point () are released. 11) of the carriage (2), which allows a longitudinal displacement of the chain box (4), which is still linked to the joining means (9) by the glutton (10) of its housing (6), until it reaches the right of the carriage (2), in a symmetrical position to the initial one, at which time the fixing means (12) are linked again to the fixing point (11), to fix the position of the chain box (4 ) with respect to the car (2).
    On the other hand, the lifting mechanism (3) can move on the carriage (2), rotating 180 ° to move from the position shown in Figure 7 to that of Figure 9, and thus bring the chain (7) 25 and the hook (25) to a position closer to the end of the beam (1) and thereby increase its useful working space. To do this, taking it from the handles (23), the support (20) of said lifting mechanism (3) is rotated inside the bearing (19) 180 °, until reaching the desired position. The wiring contained in the hose (26) accompanies the rotation of the lifting mechanism (3) with respect to the carriage (2) thanks to the pivoting capacity of the rings 30 (17) fixed in both elements.
