Problems solved by technology

[0005] The different distribution of loads acting on the various sections of the elongated member leads to different operating conditions of the clamping means arranged at different positions on the clamp, which not only require different forces on the sheath of the clamped elongated member. tangential loads, but also cause them to deform unevenly and stress the clamping members in a non-uniform manner, causing varying degrees of wear and thus requiring maintenance at different times, and usually only for some clamping members at a time Hold the device for maintenance

Embodiment Construction

[0025] exist figure 1 , reference numeral 1 generally designates a clamping device 1 designed to execute an umbilical, an elongated body CA having a substantially axisymmetric shape (wherein for the figure 1 Only a portion of an example longitudinal section is shown in dotted lines) or the laying operation of the pipe in general. In particular, these means should be distributed at a constant angular spacing transverse to a given direction D which, in use, is substantially coaxial with the central axis of the CA body portion being clamped. Thus, the clamping device 1 is arranged to apply to the body CA in use a plurality of axial forces proportional to the sum of the radial loads modulated by the coefficient of friction between the clamping device and the elongated body. Proportion. This axial force is the result of the friction generated between the sheath M and the set of saddles 1 that externally delimit the body CA. Referring again to Fig. 7, the clamping device 1 is con...

Abstract

A device (1) is designed for axially blocking an axial-symmetrical body (CA) through the application of a radial force; said device (1) having a support (10) of given angular extension, provided witha plurality of laminar bodies (20) extending longitudinally in a given direction (D); wherein said device (1) comprises at least one elongated member (30) (30') housed at least partially in a seat (32) (32') of said support (10) that extends along an axis (A) (A') parallel to said given direction (D); each said elongated member (30) (30') being housed in said respective seat (32, 32') rotatably around said axis (A)(A'); each said elongated member (30)(30') is rotoidally coupled to said support (10) with radial clearance through a respective pin (35); elastic centring means (34) being associated with each said pin (35) in order to allow each said elongated member (30) (30') to couple by friction in an angularly fixed manner to the corresponding said seat (32) (32') under the thrust of a radial force exceeding a minimum threshold value.

Description

technical field [0001] The invention relates to clamping devices. In particular, the invention relates to a clamping device adapted to axially restrain an axisymmetric body subjected to axial stress. In more detail, the present invention relates to a clamping device adapted to axially constrain an axisymmetric body subjected to an axial force by applying a radial force generated by a plurality of clamping members so as to hold each an axisymmetric body. Background technique [0002] In the field of construction where it is necessary to install elongated members, including metal pipes and umbilicals (coated with plastic), to construct pipelines for transporting fluids, power or data above and below ground or subsea, there is often a need to suspend installation, and therefore These elongated members need to be held by holding them at their ends or in the middle; this allows pre-laying operations or maintenance of the machine to be performed, or simply allows the connection ...
