Abstract
The utility model relates to a dedicated back twist frame for laying of submarine cables, which comprises bases, a support frame, a circular ladder, a roller frame for supporting optical cables and a pedal, wherein the bases are arranged at the lower end of the support frame taking the shape of a truss frame, connected with the support frame through flanges B and welded on the deck of a ship; the support frame comprises three sections which are respectively seven, three and two meters in length and connected through flanges C; the circular ladder is fixed on the support frame; inclined struts fixed on the support frame through flanges A are used for fixing the roller frame; freely rotating rollers are equidistantly fixed on the roller frame so that the surface abrasion of optical cables can be reduced and bending stress remaining in the optical cables can be released as soon as the optical cables pass through the back twist frame; four wire ropes are arranged at the upper end of the support frame; the lower ends of the wire ropes are fixed on the deck of the ship, so that stability of the back twist frame can be ensured; and the pedal is fixed on the roller frame. The dedicated back twist frame for laying of submarine cables has the advantages of simple structure, convenience of use, safety, stability and wide application range, can release bending stress remaining in the optical cables, and is applied to back twist of a standard optical cable (electric cable) with diameter Phi is less than 200 mm.
Description
Technical field
The utility model relates to a kind of support, particularly relates to a kind of extra large cable of eliminating bending stress and lays special-purpose back twist frame.
Background technology
As everyone knows, along with the develop rapidly of marine cause, existing increasing various submarine fiber cables and cable laying are to the seabed.Because of optical cable all is that dish is in circular optical cable cage or storage cable pallet in transportation, simultaneously, in order to increase freight volume all is the optical cable cage made from the minimum bending radius of optical cable or cable, in transportation, can produce bending stress, at present, directly from the optical cable cage, carry out the optical cable submarine laying by burying the cable machine, thus optical cable or cable when laying, thereby the remaining bending stress of existence makes optical cable spin, tie a knot and destroyed the overall performance of cable.
Summary of the invention
The utility model provides a kind of extra large cable of eliminating bending stress to lay special-purpose back twist frame for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it comprises base, bracing frame, circular helper, supports the turning rolls and the pedal of optical cable, base is fixed on the deck in ship structure, the bracing frame lower end that is truss-like has base, be fixed with circular helper on the bracing frame, bracing frame fixedly diagonal brace support fixation turning rolls of A flange, the bracing frame upper end has four steel cables, and the lower end of steel cable is fixed on the boat deck, is fixed with pedal on the turning rolls.
The utility model can also adopt following technical scheme:
Described base is connected with bracing frame by the B flange and is welded on the boat deck;
Described bracing frame is formed by three sections, is respectively 7 meters, 3 meters and 2 meters, and connects with the C flange;
Equidistantly on the described turning rolls be fixed with roller free to rotate.
Advantage and the good effect that the utlity model has are: simple in structure, easy to use, safety and stability can discharge remaining bending stress in the optical cable, and applied range can be suitable for
The back twist of following diameter specifications optical cable (cable).

Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows, see also Fig. 1, Fig. 2.
As shown in Figure 1: the back twist frame comprises base 1, bracing frame 2, circular helper 3, support the turning rolls 4 and the pedal 5 of optical cable, bracing frame 2 lower ends that are truss-like have base 1, as shown in Figure 2: base 1 is connected with bracing frame 2 by B flange 9 and is weldingly fixed on the deck in ship structure, bracing frame 2 is formed by three sections, be respectively 7 meters, 3 meters and 2 meters, they connect into integral body with C flange 10 respectively, bracing frame 2 internal fixation have circular helper 3, the top welding fixed idler whell frame 4 of bracing frame 2, turning rolls 4 is made of two curved plates 11 and the middle supporting stick 12 that is welded with, use fixedly diagonal brace 7 of A flange 6 on the bracing frame 2, be used for supporting and reinforcing turning rolls 4, bracing frame 2 upper ends have four steel cables 8, the lower end of four steel cables 8 is fixed on the boat deck, to guarantee the stability of bracing frame 2 and turning rolls 4, be welded with pedal 5 on the turning rolls 4, the people is the walking of safety in the above, the equidistant roller free to rotate 13 that is fixed with on the turning rolls 4, the little axle of roller 13 usefulness is supported on two curved plates 11 of turning rolls 4, optical cable can roll on roller 13, is worn to avoid the optical cable surface.
During use, after the back twist frame is fixedly mounted on the boat deck, being with pull rope to climb to the back twist top of the trellis along circular helpers 3 in the bracing frame 2 by the staff puts down pull rope along back-up roller wheel carrier 4, one end of pull rope is connected on the dilatory head of optical cable of optical cable cage on the ground, on the pull rope other end connection traction electric machine above deck, optical cable is drawn in the optical cable cage by pull rope by traction electric machine, can discharge remaining bending stress in the optical cable (cable) by whole back twist frame, then, the cable machine is buried in the optical cable access, by burying the submarine laying that the cable machine carries out optical cable (cable).
Its advantage is: simple in structure, easy to use, safety and stability can discharge remaining bending stress in the optical cable, and applied range can be suitable for
The back twist of following diameter specifications optical cable (cable).
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
