    [0003] OBJECT OF THE INVENTION
    [0005] The present invention refers to a rotary support device for a torsion beam, coupled to a support pillar, of special application in solar power plant installations.
    [0007] More particularly, the invention deals with a support device comprising a clamp, a bushing that houses a beam and a retaining piece by means of which the bushing is retained in the clamp, so that the parts used are reduced, the adjustment of geometric tolerances is correct and the positioning of the turning support is simplified for the operator, since the device consists of few parts and no additional tools are necessary.
    [0009] BACKGROUND OF THE INVENTION
    [0011] It is known in the state of the art, the use of devices on which the load of a beam is supported at the same time that it is allowed to rotate. For example, in the field of solar power plant installations there is a surface with a plurality of solar panels joined by a beam that pivots on a north-south axis to orient the panels depending on the position of the sun. This beam is embraced by a bearing that allows it to rotate, arranged in a clamp fixed to a support beam, which transmits the loads to the foundation.
    [0013] For example, document ES2397777 includes a support that comprises a clamp that surrounds some pieces that hug a turning beam, where the plastic pieces have a spherical shape on the outside corresponding to a reciprocal shape inside the bracket, such that the beam is axially retained by the clamp. The clamp is composed of two segments that are screwed together and the clamp confining the two pieces.
    [0015] Another example of a rotating support includes a clamp formed by a single piece or ferrule in which two plastic pieces are inserted that hug the rotating beam. Additionally, some buckles are used as retainers for the plastic pieces.
    [0016] However, such devices have a number of disadvantages. On the one hand, the use of clamping screws produces a constant compression in the plastic parts that can cause the joint to loosen and the plastics to crack. In the case of the use of buckles, the buckle itself can cause excessive friction with the clamp. Furthermore, the number of components required is very high and installation by the operator complex.
    [0018] DESCRIPTION OF THE INVENTION
    [0020] The present invention aims to solve some of the problems mentioned in the state of the art.
    [0022] The present invention discloses a rotary support device for a torsion beam, attachable to a support pillar. The support device comprises a bracket, which can be coupled to the support pillar with a cylindrical inner area, a bushing, intended to be positioned inside the bracket, which can be rotated together with the torsion beam with respect to the bracket, and a retainer piece.
    [0024] The bushing comprises a lower part comprising a first central sector that has, in the longitudinal direction, an outer zone of partially cylindrical shape complementary to the inner zone of the clamp. The lower part comprises two lower distal sectors that comprise a first projection respectively that extends in height with respect to the central sector that constitutes a stop in the longitudinal direction in the mounting situation of the lower part in the bracket, preventing the lower part from exiting. clamp. The lower part further comprises a lower cavity.
    [0026] The bushing comprises an upper part that has a second central sector that has, in the longitudinal direction, an outer zone of partially cylindrical shape complementary to the inner zone of the clamp. The upper part also comprises a posterior upper distal sector, which comprises a second projection that extends in height with respect to the second central sector which constitutes a stop in a longitudinal direction in the mounting situation of the upper part in the bracket. The upper part has an anterior upper distal sector, which comprises a slot. The upper part also comprises an upper cavity, where the upper cavity is arranged facing the lower cavity in a mounting situation so as to form a recess intended to accommodate a torsion beam.
    [0028] The retaining piece is engagable in the groove so that in an assembly situation it protrudes in height with respect to the bracket, preventing movement of the bushing relative to the bracket in the longitudinal direction.
    [0030] In this way, in an assembly situation, the lower part of the bushing is retained in the clamp in the longitudinal direction in both directions thanks to the aforementioned.
    [0032] The central zone of the first central sector has a partially cylindrical complementary shape so that a movement of the lower part is allowed with respect to the torsion beam. The lower part is the first to be mounted inside the clamp, since as it has the first projections as a stop, it needs clearance to be inserted.
    [0034] When placing the lower part preferably the torsion beam is not yet in place so it can be easily inserted. If the beam is in place, there is an upper clearance that allows the bracket to be moved, for example, with respect to the structure in order to insert the lower piece. The lower cavity allows to partially embrace the torsion beam and therefore the shape of the lower cavity is determined by the shape of the beam.
    [0036] The upper part is inserted into the clamp through the anterior upper distal sector that comprises the slot, as it is the only sector that does not have projections and can be positioned with a sliding movement in the longitudinal direction. The retaining piece in a mounting situation in the groove of the upper piece protrudes in height with respect to the clamp, thereby blocking the movement of the upper piece in both directions in the longitudinal direction and the bushing is retained in the clamp, being able to rotate together with the torsion beam and without being able to move longitudinally. This allows, in an assembly situation, with the lower part mounted, the upper part can be easily inserted and the bushing retained. The central area of the second central sector has a partially cylindrical complementary shape so that a movement of the upper part with respect to the torsion beam is allowed.
    [0038] The upper part also has an upper cavity that allows the torsion beam to be hugged and its shape is determined by the shape of the beam. When the upper cavity faces the lower cavity, a socket gap is generated. This hole describes a section complementary to a torsion beam cross section, which can be polygonal, circular or a combination of both, so that it houses a torsion beam with a cross section of this geometry. When the torsion beam rotates, it draws the upper part and the lower part of the bushing with it, allowing it to rotate within the clamp. In this way the device supports the torsion beam allowing it to rotate.
    [0040] The clamp confines the upper and lower part of the gland, leaving minimal space to allow rotation of the gland within the clamp. The confinement of the pieces is achieved by avoiding the use of clamping screws, which can cause the joint to loosen and the pieces to crack. In this way, the mechanical joints between the components are eliminated, reducing the risk of breakage, fatigue, etc.
    [0042] The clamp can be attached to the support pillar, allowing it to adopt different heights and inclinations, so that it can absorb slopes in the terrain and positioning errors of the support pillar. The clamp can be attached to the support post preferably by means of a regulation intermediate piece and mechanical connecting elements. This is especially advantageous since the device is especially applicable in solar panel installations, where the terrain is uneven so that these deviations can be compensated by the support and regulation pillar.
    [0044] The upper part can comprise at least one vertical guide inside the groove and the retaining part can comprise at least one projection slidable along the vertical guide. This configuration guides the insertion movement of the retainer into the groove, in addition to better retaining the retaining piece and minimizing play. This projection can be complementary to the vertical guide, having a width slightly less than the width of the vertical guide so that the retaining piece is better fixed in the groove of the upper piece. The thickness of the projections corresponds to that of the vertical guide so that in addition to guiding the piece, it fits the piece better.
    [0046] Additionally, the upper part can comprise at least one vertical partition inside the groove. This vertical partition extends from side to side of the inner surfaces that define the slot and there may be for example two vertical partitions parallel to each other. The retainer may comprise a slot so that the slot fits into the septum. Thanks to this vertical partition, the guide of the retaining piece within the slot is carried out with greater precision and the end of the vertical partition abuts the slot preventing the retaining piece from moving beyond its predetermined position in the assembly situation.
    [0048] The upper part can comprise two channels on the sides inside the groove and the retaining part can comprise two arms that are inserted into the channels in the assembly situation. This increases the surface of the retaining piece inserted in the groove, which gives it greater stability.
    [0050] Additionally, the upper part can comprise a housing adjacent to the channels inside the groove and the retaining piece comprises at least one anchoring flange located in the lower area of the arms, which can be nested in the housing. This is especially advantageous since the anchoring flange engages in the housing forcing the retaining piece to adopt the predetermined mounting position.
    [0052] The retaining piece may comprise an opening facing the anchoring flange that allows the anchoring flange to be flexed to facilitate its anchoring in the housing. That is to say, the anchoring flange is of the collapsible type and upon entering the groove channels it flexes towards the opening and upon reaching the housing it expands again, preventing the retaining piece from coming out of the groove.
    [0054] Additionally, the retaining piece can comprise an upper bridge that joins the two arms in which at least one projection and at least one slit are defined, which is constituted in a gripping surface that facilitates its handling. The upper bridge is understood to be the area that protrudes from the clamp. The retaining piece can incorporate a symmetrical gripping surface, so that imbalances and possible wear are avoided during use. The bridge comprises at least one lateral prominence that extends in height. In this way, the handling and introduction by the operator of the retaining piece is easier.
    [0056] The sleeve can preferably be made of a plastic material. The plastic material is favorable when there is a lot of friction so it is suitable to be used in the bush. In addition, it must have adequate properties to extend its useful life taking into account the temperature conditions to which it will be exposed, in extreme heat situations. Materials are preferably used that have good behavior against UVA rays, do not absorb moisture and are resistant to abrasion.
    [0057] The clamp can preferably be of a metallic material. By having to receive impacts and forces from the support beam, the metallic material presents better behavior in the face of this type of stress.
    [0059] Additionally, the upper part and the lower part may comprise complementary walls and recesses in the area where they face each other, so that they are tighter and better retained.
    [0061] DESCRIPTION OF THE DRAWINGS
    [0063] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

    [0072] PREFERRED EMBODIMENT OF THE INVENTION
    [0074] Figure 1 shows a perspective view of the device (1) for rotating support of a torsion beam (11) that can be coupled to a support pillar (12) comprising a bracket (2) that can be connected to the support pillar (12). Preferably, the device (1) is coupled to the support pillar (12) by means of an intermediate regulating piece (13) to which it is connected by mechanical connection elements.
    [0075] Inside the clamp (2) is seen a bushing (3) that houses the torsion beam (11) and which has the possibility of turning together with the torsion beam (11). The bushing (3) comprises an upper part (5), a lower part (4) and a retaining part (7) that can be seen in Figure 3 in a position prior to assembly.
    [0077] Figure 2 shows a sectional view according to A-A made in the device (1) of Figure 1, according to the present invention. Figure 2 shows the device (1) in an assembly situation with the clamp (2) that embraces the lower part (4) and the upper part (5) of the bushing (3). The lower part (4) has first projections (42) in lower distal sectors. These projections (42) protrude from the bracket (2), retaining the lower part (4) in the bracket (2).
    [0079] The upper part (5) comprises a second projection (52) in a posterior upper distal sector, so that this second projection (52) retains the upper part (5) in one direction. In the upper anterior distal sector the upper part (5) comprises a groove (6). In the groove (6) the retaining piece (7) is inserted so that in an assembly situation this retaining piece (7) protrudes from the clamp (2). In this way the upper part (5) is retained by the second projection (52) and by the retaining part (7).
    [0081] Figure 3 shows a perspective view of the device (1), according to the present invention in which the lower part (4) and the upper part (5) of the bushing (3) are seen disassembled. The lower part (4) is illustrated which comprises a first central sector (41) having an outer zone of partially cylindrical shape. This cylindrical area is complementary to the inner area (21) of the clamp (2). The lower part (4) comprises two lower distal sectors comprising two first projections (42) respectively and a lower cavity (43).
    [0083] Figure 3 also shows an upper part (5) with a second central sector (51) that has an outer zone of partially cylindrical shape complementary to the inner zone (21) of the clamp (2). It further comprises an upper posterior distal sector with a second projection (52) that extends in height with respect to the second central sector (51) and an anterior upper distal sector comprising the groove (6). The upper part (5) also has an upper cavity (53). The upper cavity (53) is arranged facing the lower cavity (43) in an assembly situation so as to form a recess intended to house the torsion beam (11). The upper part (5) is inserted through the anterior upper distal sector (52) in the direction of the arrow.
    [0084] Preferably, both the upper cavity (53) and the lower cavity (43) have a section complementary to the section of the torsion beam (11).
    [0086] Figure 4 shows a view of an intermediate mounting situation of the device (1) in perspective, according to the present invention. The lower part (4) and the upper part (5) are seen mounted inside the bracket (2) and in turn hugging the torsion beam (11). In this situation the lower part (4) cannot come out of the clamp (2) due to its first projections (42). However, the upper part (5) could come out of the bracket (2) in a sense of the longitudinal direction because it only has the second projection (52). To fix the position of the upper part (5), the retaining part (7) is engagable in the groove (6).
    [0088] Figure 5 shows a sectional view according to B-B of the groove (6), according to the present invention. The groove (6) comprises at least one vertical guide (62). Projections (71) of the retaining piece (7) shown in Figure 6 slide along these vertical guides (62). The vertical guides (62) extend to the outer area of the upper piece (5). It is also observed that the slot (6) comprises vertical partitions (61). The height of the vertical partition (61) serves as a stop for the retaining piece (7).
    [0090] Surrounding the upper cavity (53) an edge (65) is seen. A housing (64) is observed in the lower corners near the groove (6) destined to house the anchoring flange (73). The groove (6) comprises two channels (63) on the sides limited by a joining zone (66) that delimits the groove (6). In another alternative embodiment, the edge (65) is dispensed with, leaving only a portion of material near the corners to form a housing (64) for the anchor flange (73).
    [0092] Figure 6 shows a perspective view of the retaining piece (7), according to the present invention. The retaining piece (7) has projections (71) slidable along the vertical guide (62). Each of the projections (71) is in a corresponding position with each side of the vertical guides (62) so that they fit together. In addition, there are slits (72) that fit into the vertical partitions (61). The number of slits (72) and projections (71) can vary as long as it corresponds to that of the vertical guides and vertical partitions (61) of the slot (6). The retaining piece (7) has two arms (75) that are inserted into the channels (63) of the slot (6).
    [0093] Figure 6 also shows an upper bridge (76) that joins the two arms (75) in which the projections (71) and the slits (72) are defined, which is constituted in a gripping surface that facilitates their handling. An opening (74) is also seen facing an anchor flange (73) so that the anchor flange (73) can flex towards the opening (74). The upper bridge (76) can be partially curved on the outside. Preferably the upper bridge has two prominences (77).
