In practical operation, described tensioning apparatus includes support, and hydraulic cylinder and guide post are set on this support; Two chains parallel to each other are formed a special broadband chain by connecting clamping plate, chain one end in broadband is connected on the hydraulic cylinder piston rod by the hook on a pair of guiding wheels, the other end by another to guiding on the wheels hook and cooperate guide post to be connected on the hydraulic cylinder body.Above-mentioned hydraulic cylinder can be the rod-pulling type plunger case.
Above-mentioned pipeline is in the mouthpart, and the cross section of described sprocket device is " M " shape, and it is articulated in the described chain storage tank, and the sprocket of locating that described chain passes the chain storage tank is fastened in the teeth groove of sprocket device.In addition, the contact-making surface of described connecting cleat and pipeline to be connected, for the corresponding circular arc of this pipeline to be connected.
According to the caliber difference, the quantity of connecting cleat can be adjusted accordingly, such as: 7,6,5,4 or 2.
The utility model is owing to take above design, and it has the following advantages:
1, the utility model is realized tightening up of chain by hydraulic cylinder and is unclamped; Connecting cleat on the chain can allow the stressed centering of pipe end rigidity; The sprocket device guarantees chain and the flexible connection of connecting cleat; Directive wheel has dual-use function on the hydraulic cylinder and be connected in, and has both guaranteed can move at pipe surface when chain tightens up, and avoids plunger rod to be subjected to moment of flexure, is again the hook of broadband chain.
2, the utility model centering of can be used for the metallic conduit of different tube diameters clamp to be adjusted, and accommodation is big, is particularly suitable for carrying out under water, the accurate counterpart work before the welding of the double-deck oil and gas pipes of land list.

The specific embodiment
As Fig. 1~shown in Figure 6, for a kind of pipeline provided by the utility model to mouthpart, it includes:
At least one group of connecting cleat 1, it is evenly distributed on the outer wall at pipeline to be connected 2 two ends, unfixing between connecting cleat 1 and the pipeline, in the process of counterpart, connecting cleat 1 can move along pipeline outer wall, the two ends of each connecting cleat 1 are respectively arranged with a chain storage tank 11, are provided with sprocket device 12 in this chain storage tank 11;
Two chains 3 parallel to each other, it passes the chain storage tank 11 of connecting cleat 1 two ends correspondence respectively, and is set on the outer wall of pipeline 2 to be connected;
Four guiding wheels 4, it connects the end that each chain 3 is set respectively;
One tensioning apparatus 5, it is arranged between four guiding wheels 4.
In the utility model, above-mentioned tensioning apparatus 5 specifically includes support 51, and hydraulic cylinder 52 and guide post 53 are set on the support 51.Structural principle schematic diagram of the present utility model as shown in Figure 1, two chains 3 parallel to each other are formed a special broadband chain by connecting cleat 1, chain one end in broadband is connected on the hydraulic cylinder piston rod 521 by the hook on a pair of guiding wheels 41, the other end by another to guiding on the wheels 42 hook and cooperate guide post 53 to be connected on the hydraulic cylinder body 522.Can think during counterpart that the distance of LL is constant, when piston rod 521 elongations, the L distance reduces, and the chain tension reaches application of force counterpart purpose.Again specifically, hydraulic cylinder 52 can be the rod-pulling type plunger case.
Cooperate Fig. 4, Fig. 5, shown in Figure 6, sprocket device 12 specifically, its cross section is " M " shape, it is articulated in the chain storage tank 11, and chain 3 passes the sprocket of locating 31 of chain storage tank 11 and is fastened in the teeth groove of sprocket device 12.Like this, when chain 3 was tightened up, sprocket device 12 rotated at the drive lower edge of sprocket 31 pivot 13, and sprocket 31 then moves to the teeth groove of front from a teeth groove of sprocket device 12 back.In addition, the contact-making surface of connecting cleat 1 and pipeline 2 to be connected, for these pipeline 2 corresponding circular arcs 13 to be connected; Such benefit is that arc transition is steady, smooth in the counterpart tension chain process, stress is concentrated little.
Connecting cleat 1 in the foregoing description, its quantity can be adjusted accordingly or even not use connecting cleat according to the caliber difference, as Fig. 7, shown in Figure 8, in general, 24 " pipeline is with 7 connecting cleats, and 24 "~20 " pipeline is with 6; 20 "~15 " pipeline is with 5; 15 "~6 " pipeline is with 4, and clamping plate evenly distribute 6, and " pipeline is with 2 connecting cleats or need not.
When the utility model uses, by workboat complete machine is delivered to assigned address under water, and be positioned on the pipeline to be processed by the diver, the axis normal of pipeline is in the cylinder plunger bar.After finish the location, on workboat, carry out or diver's execute-in-place all can by operating personnel.
With the underwater operation is example, simply introduces concrete using method of the present utility model:
1. hydraulic cylinder module and connecting cleat are installed respectively.
2. at dry type environment or underwater environment, manual pump, take-up device, clamping plate chain etc. are transferred near the pipeline to be processed, in place by operating personnel.On pipeline when in place, two directive wheels on the hydraulic cylinder module are costed respectively by the end of counterpart two segment pipes, hang the broadband chain on the hook of directive wheel, the chain other end hangs over another on the directive wheel after holding pipeline to be processed, screws guide post with ratchet spanner.
3. operating personnel are to the hydraulic hand-pump application of force.Hydraulic cylinder piston rod stretches out, and the broadband chain tightens up, and reaches pipeline counterpart purpose, after spot welding is finished, removes and can carry out root bead to mouthpart.
The utility model can be used for counterpart and set round different tube diameters metallic conduit, for reliable, accurate welded pipe line provides safeguard.
