Embodiment

For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing and describe embodiment of the present utility model in detail.

As shown in Figure 1, 2, the cable pillar of the utility model one embodiment, comprises body 1 and is arranged on the centralising device 2 in body 1.Body 1 is for being connected to platform (offshore oilfield platform) brace summer 200, for cable 100, pass, with avoid cable 100 to rock and brace summer 3 collisions or a plurality of cable 100 between rock collision; Centralising device 2, for being sleeved on cable 100 peripheries, plays a protective role to cable 100, avoids cable 100 directly and body 1 inwall contact-impact and impaired etc.

During installation, body 1 is to be connected on brace summer 200 with upright state, and corresponding with the position of suspension wires on platform; Preferably be connected on horizontal brace summer 200, and be positioned at b.s.l..At body, within 1 week, in side, be also provided with connecting tube 3, body 1 is connected on brace summer 200.Preferably, at connecting tube 3 free ends, steel plate 31 is set, by steel plate 31, is welded on brace summer 200, thereby body 1 is connected on brace summer 200.Body 1 is J type or arc.During use, cable 100 vertically turns and passes body 1 after an angle and curved and extend the hanging position on platform from penetrating body 1 under water in body 1.According to the guiding needs of many cables 100, can on brace summer 200, connect many pillars in interval.Due to the body 1 of pillar, to be directed to the angle that cable hangs different, and during welding, each body 1 keeps inclination angle also different, and inclination angle angle is as can be 1.25 °, 2.0 °, 5.5 °, 9.5 ° and 12 ° etc.

Cable 100 diameters are generally less than internal diameter of tube body, and it is revocable in body 1, in order to prevent that cable 100 from rocking in body through after body 1, friction occurs and damage with body 1 inwall, at the interior centralising device 2 that arranges of body 1, protect cable 100.Centralising device 2 comprises several for being sleeved on the first joint piece 21 of cable 100 peripheries, and several the first joint pieces 21 are fastened and connected diametrically successively, can form a serobila.In the present embodiment, each first joint piece 21 one end has annular sphere 211, and the other end has the annular cambered surface 212 of the indent matching with annular sphere 211.In several the first joint pieces 21 that are fastened and connected, the annular cambered surface 212 of rear one first joint piece 21 is fastened on the annular sphere 211 of last the first joint piece 21.Fastening place between every two the first joint pieces 21 for closely, can be gapped, allows relatively to swing between the first joint piece 21, makes the serobila that forms flexible.And the setting of annular sphere 211 and annular cambered surface 212 can not damage the oversheath of cable 100.

Preferably, each first joint piece 21 can be by two symmetrical assembled formation of semi-circular shell.When cover installs on cable 100, successively two return bend shell corresponding matching of each the first joint piece 21 are arrived to cable 100 both sides, by securing members such as screws, two return bend shells are coupled together, can on cable 100, form the first joint piece 21.

Cable 100 is through after body 1, crooked along opening periphery in order to prevent in cable 100 parts at body 1 upper and lower end opening 11,12 places, generally on the cable 100 that is positioned at body 1 upper end open 11 and/or lower ending opening 12 places, can be provided with and stop bent device, in the present embodiment, on the cable 100 that is positioned at body 1 upper end open 11 and lower ending opening 12 places, be separately installed with and stop bent device 110,120.Body 1 upper end open 11 and/lower ending opening 12 is horn-like, is beneficial to the bent device 110,120 that stops on cable 100 and coordinates.

This centralising device 2 also can comprise a second joint part 22, the opposite end of second joint part 22 all has annular cambered surface 221, second joint part 22 is fastened on the annular sphere 211 of one first joint piece 21 with the annular cambered surface 221 of one end, and is connected on one first joint piece 21 that is positioned at outside.The annular cambered surface 221 of these second joint part 22 other ends for stop bent device 110 and be connected.Equally, this second joint part 22 also can, by two symmetrical assembled formation of semi-circular shell, adopt the mode cover identical with the first joint piece 21 to install on cable 100.

Wherein, on cable 100 corresponding body 1 upper and lower end opening 11,12 places stop bent device 110,120 can be identical, also can be different.In the present embodiment, the tubular body 121 that bent device 120 comprises a taper is stopped at corresponding body 1 lower ending opening 12 places, is wherein provided with through hole and passes for cable 100.This tubular body 121 with the large one end of its diameter towards body 1 lower ending opening 12, and tubular body 121 these ends are provided with a flange 122 for being connected with body 1 lower end, the end face of body 1 lower ending opening 12 is formed for stopping with this on cable 100 flange face 121 that bent device 120 docks; On flange 122, be also provided with a solid joint 123 for being connected with centralising device 2, this permanent joint 123 is mainly connected with the first joint piece 21, so its one end that connects the first joint piece 21 corresponds to the annular sphere coordinating with the annular cambered surface 212 of the first joint piece 21.The bent device 110 that stops at corresponding body 1 upper end open 11 places comprises that one has the tubular body 111 that through hole passes for cable 100, this tubular body 111 is similarly taper, and with the large one end of its diameter towards body 1 upper end open 11, while being connected with body 1, this end can partial insertion in body 1, and on this end, be provided with a permanent joint 112 for being connected with centralising device 2, this permanent joint 112 is mainly connected with second joint part 22, so its one end that connects second joint part 22 corresponds to the annular sphere coordinating with the annular cambered surface 221 of second joint part 22.

During use, can first the position of corresponding body 1 upper end open 11 on cable 100 be installed to one and stop bent device 110, then overlap and load onto centralising device 2 on cable 100 in stopping bent device 110 belows, then cable 100 be passed to body 1 under water.Wherein, cable 100 is through after body 1, and on it, one stops bent device 110 and corresponds to body 1 upper end open 11 places, and 2 of centralising devices are positioned at body 1.Then on cable 100, corresponding body 1 lower ending opening 12 places install another and stop bent device 120, and this stops bent device 120 and is connected with centralising device 2 by permanent joint 123 on it, and is fixedly connected with the flange face 121 of body 1 lower end by its upper flange 122.The cable 100 that stretches out body 1 is vertically pulled to hanging position on platform and is fixed, can complete the installation that coordinates of cable 100 and pillar.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
