CLEARANCE REDUCING DEVICE AND HELIOSTAT WITH CLEARANCE REDUCED STRUCTURE

摘要

Clearance reducing device (19) for fixing a hinge pin (20) to a pivoting connection, for example, a pivoting connection of a solar energy capture structure. Advantageously, said clearance reducing device (19) comprises a clamping support (21), integrally incorporated in a lug (8) of said pivoting connection, provided with through holes, to which a mechanical pulling element (22), arranged as a clamp around the hinge pin (20), is connected. The present invention also relates to a heliostat with dual-axis tracking capacity, comprising: a pedestal (1); a torque tube (2); a plurality of arms (9) to which a plurality of facets (11) configuring the heliostat grid is fixed; an azimuth drive (3) of the torque tube (2) arranged in the pedestal (1); a horizontal support (4) arranged at the upper end of the pedestal (1), and a clearance reducing device (19).
