A device for supporting and/or guiding a first structure that includes machines, instruments and/or structures in general, particularly for supporting and/or guiding a telescope, relative to a second structure, includes a sliding system with a slide block adapted to slide relative to the second or the first structure; for a fluid, a chamber that is separate from and independent of the sliding system and that includes a first portion fixed to the sliding system and a second portion adapted to be associated with the first or the second structure; a fluid circuit that is also separate from and independent of the sliding system and that communicates with the chamber to control the passage of the fluid into and from the chamber; and an elastic member housed in the chamber to absorb the oscillations between the first and the second portion.
A device (2) for supporting and/or guiding a first structure (12) comprising machines, instruments and/or structures in general, particularly for supporting and/or guiding a telescope, relative to a second structure (10), characterised by comprising:
A device as claimed in one or more of the preceding claims, characterised by comprising a first configuration, to be used in the absence of oscillations external to the device, in which said chamber (6) is filled with pressurized fluid, and said elastic means (26) are at least partly compressed, hence rendering rigid the combination defined by said device (2) and by said first structure (12) comprising machines, instruments and structures in general.
A device as claimed in one or more of the preceding claims, characterised by comprising a first subcircuit (33) which is configured and controlled such as to maintain said chamber (6) filled with pressurized fluid.
A device as claimed in one or more of the preceding claims, characterised by comprising a second configuration, to be used in the presence of oscillations external to the device, in which said fluid circuit (8, 33) controls the quantity of fluid present in said chamber (6) such that said elastic means (26) oppose the oscillatory movements between said second portion (24) and said first portion (22).
A device as claimed in one or more of the preceding claims, characterised by comprising a damping subcircuit (35, 80) configuration and controlled such as to dissipate the energy deriving from said oscillations between the second portion (24) and the first position (22).
A device as claimed in one or more of the preceding claims, characterised in that said damping subcircuit (35) is housed external to said second portion (24) and said first portion (22).
A device as claimed in one or more of the preceding claims, characterised in that said damping subcircuit (35) is configured to control the passage of fluid entering and/or leaving said chamber (6).
A device as claimed in one or more of the preceding claims, characterised in that said damping subcircuit (80) is incorporated into said second portion (74) and/or into said first portion (68).
A device as claimed in one or more of the preceding claims, characterised in that said elastic means comprise at least one spring (26), which is housed in said chamber (6) and is interposed between said second portion (22, 68) and said first portion (24, 74).
A device as claimed in one or more of the preceding claims, characterised in that said elastic means comprise, for each spring (26), a guide cylinder (28) which is positioned inside the spring (26) itself.
A device as claimed in one or more of the preceding claims, characterised in that said sliding system (4) comprises a hydrostatic slide block.
A device as claimed in one or more of the preceding claims, characterised in that said at least one spring (26) is configured such that, in combination with pressurized fluid in the chamber (6), it balances the external load to which the combination defined by the device (2) itself and by the first structure comprising said machine/instrument/structure 12 to be supported and/or guided, is subjected.
A device as claimed in one or more of the preceding claims, characterised by comprising an electronic control unit which controls the valves of the fluid circuit (8) communicating with said chamber (6), and/or the valves of the damping subcircuit (35, 80).
A device as claimed in one or more of the preceding claims, characterised by comprising means for the electronic or mechanical sensing of a signal which identifies the presence or the arrival of oscillations, in order to hence cause said device (2) to pass between said first and said second configuration.
A device as claimed in the preceding claim, characterised in that said sensing means are incorporated into the device itself or are positioned external thereto and are connected to the device control unit.
A device as claimed in one or more of the preceding claims, characterised in that said first structure (12) and said second structure (10) comprise corresponding surfaces which face each other vertically or horizontally or are inclined to the vertical by an angle of less than about 90°.
A device as claimed in one or more of the preceding claims, characterised in that said second structure comprises an underlying support and/or guide structure (10), said first structure (12), which comprises said machine, instrument or structure to be supported and/or guided, being upperly associated with said second portion (24) of said chamber (6).
A platform for supporting and/or guiding machines, instruments and structures, characterised by being supported and/or guided by at least two devices (2) in accordance with one or more of the preceding claims, and by comprising at least one electronic supervision unit for the command and control of the oil hydraulic circuits (8) of each of said at least two devices (2).
