Abstract
Pinza para elevación de bloques de hormigón, formada por una pinza de dos brazos con placas de ajuste sobre los vértices superiores de la placa a elevar, y articulada en su punto central en el mismo eje de giro del vértice inferior de un rombo deformable, que lleva en su vértice contrario el punto de sujeción a la grúa que se emplee, para que, al deformarse abriendo sus brazos, se cierre el ángulo de la pinza sujetando firmemente al bloque. En este rombo deformable, existe un dispositivo de seguridad, formado por una palanca en ángulo recto con eje de giro en su ángulo, y brazo vertical con muesca longitudinal en la que discurre un tetón fijo, mientras el brazo horizontal, descansa sobre el lado mayor de una pieza rectangular, solidaria de un tronquete de dientes curvos en el que encastra una uña de sujeción, susceptible de dejar libre al trinquete cuando se efectúa la tracción, girando éste y situando bajo el lado horizontal de la palanca en ángulo recto al lado menor del rectángulo, basculando éste y liberando el lado vertical del tetón fijo, permitiendo al rombo que abra sus lados y a la pinza que cierre su ángulo, produciéndose la sujeción del bloque.Clamp for lifting concrete blocks, formed by a two-arm clamp with adjustment plates on the upper vertices of the plate to be raised, and articulated at its central point on the same axis of rotation of the lower vertex of a deformable rhombus, which it carries the point of attachment to the crane that is used in its opposite vertex, so that, when deforming by opening its arms, the angle of the clamp is closed, firmly holding the block. In this deformable rhombus, there is a safety device, formed by a lever at right angles with an axis of rotation at its angle, and a vertical arm with a longitudinal notch in which a fixed bolt runs, while the horizontal arm rests on the greater side. of a rectangular piece, integral with a curved teeth trunk in which a clamping nail is embedded, capable of freeing the ratchet when traction is carried out, turning it and placing it under the horizontal side of the lever at right angles to the minor side of the rectangle, tilting it and releasing the vertical side of the fixed stud, allowing the rhombus to open its sides and the clamp to close its angle, producing the clamping of the block.
