Abstract

A measurement device for measuring mechanical tensions in wires consisting of a metallic parallelepiped-shaped body (1), with a mechanical construction (4) for extensometric gauges from which supporting and fixing elements (2, 2′) stem from either one or both its faces, and which are provided with perimetric indentations. The supporting elements are three rods or rigid pivots arranged on the nodes of a tetractys pattern with respect to the longitudinal axis of the body, one of them (2′) being in an extremal position, mobile, retractile by shift both forwards and backwards in order to allow for it to be brought back to its forward operating position.

Claims

1. A measurement device for measuring mechanical tensions in wires comprising

a parallelepiped-shaped body (1) tangibly elongated and made of metallic material,

supporting and wire-fixing elements (2, 2′

) attached to the parallelepiped-shaped body,

perimetric indentations furnished at the supporting and wire-fixing elements (2, 2′

) destined to keep a wire (3) in place,

a mechanical construction (4) furnished on a surface of the parallelepiped-shaped body (1) to house extensometric gages generating signals corresponding to the levels of load on the wire (3) on which the load is installed, wherein such supporting and wire-fixing elements (2, 2′

) project out through at least one of the faces of the parallelepiped-shaped body (1), wherein the supporting and wire-fixing elements (2, 2′

) are distributed throughout such face and are orthogonally projecting with respect to the plane of the face through which the supporting and wire-fixing elements (2, 2′

) emerge.

2. The measurement device for measuring mechanical tensions in wires, according to claim 1, wherein the supporting and wire-fixing elements (2, 2′

) are three rigid rods of pivots that project out through one of the faces of the parallelepiped-shaped body (1) placed on the nodes of a tetractys pattern with respect to the longitudinal axis of this parallelepiped-shaped body (1).

3. The measurement device for measuring mechanical tensions in wires, according to claim 1, wherein the supporting and wre-fixing elements (2, 2′

) have different dimensions.

4. The measurement device for measuring mechanical tensions in wires, according to claim 1, wherein one (2′

) of the supporting and wire-fixing elements, in an extremal position, is mobile, retractile and withdrawable by shifting forward and backward, in such a way that it can be hidden away by backward shift during the first stage of the assembly of the measurement device on the wire (3), and then brought back to the forward operative position when the body (1) of the measurement device has been brought to the appropriate position against the resistance to flexing by the mechanical tension induced by the load on such cable (3); and

because the body (1) of the measurement device has been endowed, on its rear face, with an isolated surface portion (6), bounded by lowered fringes (7a, 7b) upper and lower, such surface portion being sized and configured in such a way that it allows the engaging of a tool, such as a wrench (8), either adjustable or not, with which to exert a levering action during the operation of rotating the body (1) of the measurement device in order to attach the wire (3) to the supporting elements, both fixed (2) and mobile (2′

).

5. The measurement device for measuring mechanical tensions in wires, according to claim 1, wherein the provision of incorporating a protecting case (9), is adaptable and fixable by sheer pressure to the body (1) of the sensor.

6. A measurement device for measuring mechanical tensions in wires which, being of the kind made out of a parallelepiped-shaped body (1) tangibly elongated of metallic material, presenting supporting and wire-fixing elements (2, 2′

) endowed with a perimetric indentation destined to keep the wire (3) in place and having the body (1) on its surface a mechanical design (4) to house extensometric gages generating the signals corresponding to the levels of load on the wire (3) on which it is installed, wherein such supporting elements (2, 2′

) project out through at least one of the faces of the body (1), distributed throughout such face and orthogonally projecting with respect to the plane of the face through which they emerge.

7. The measurement device for measuring mechanical tensions in wires, according to claim 6, wherein the supporting elements (2, 2′

) are three rigid rods of pivots that project out through one of the faces of the body (1) placed on the nodes of a tetractys pattern with respect to the longitudinal axis of this body.

8. The measurement device for measuring mechanical tensions in wires, according to claim 6, wherein the supporting elements (2, 2′

) have different dimensions.

9. The measurement device for measuring mechanical tensions in wires, according to claim 6, wherein one (2′

) of the supporting elements, in extremal position, is mobile, retractile by shift forward and backward, in such a way that it can be hidden away by backward shift during the first stage of the assembly of the sensor on the wire (3), and then brought back to the forward operative position when the body (1) of the sensor has been brought to the appropriate position against the resistance to flexing by the mechanical tension induced by the load on such cable (3); and

because the body (1) of the measurement device has been endowed, on its rear face, with an isolated surface portion (6), bounded by lowered fringes (7a, 7b) upper and lower, such surface portion being sized and configured in such a way that it allows the engaging of a tool, such as a wrench (8), either adjustable or not, with which to exert a levering action during the operation of rotating the body (1) of the sensor in order to attach the wire (3) to the supporting elements, both fixed (2) and mobile (2′

).

10. The measurement device for measuring mechanical tensions in wires, according to claim 6, wherein the provision of incorporating a protecting case (9), is adaptable and fixable by sheer pressure to the body (1) of the measurement device.
