Abstract
The utility model relates to a connecting device capable of continuously adjusting curvature of a deep water S-shaped stinger. The connecting device is provided with a rotating sleeve, a threaded through hole is formed in the rotating sleeve and threaded rods are installed at the two ends of the rotating sleeve, wherein the depth of the threaded rods which are screwed into the rotating sleeve can be controlled. The connecting device capable of continuously adjusting the curvature of the deep water S-shaped stinger has the beneficial effects that the length of the deep water S-shaped stinger can be adjusted by rotating the middle sleeve only; not only can the problem that the curvature of the stinger cannot be adjusted be solved, but also the curvature of the stinger can be adjusted without requiring the assistance of a crane, the workload of curvature adjustment is reduced and the working efficiency is improved.
Description
Technical field
The utility model relates to pipe support rack, relates in particular to a kind of connection set that can regulate continuously S-shaped stinger used in deepwater curvature, belongs to Offshore Engineering field.
Background technique
Pipe support rack is the important device of laying deep water S type submarine pipeline, in deep water S type undersea pipe-laying process, for pipeline provides a supporting role, and makes pipeline enter water with suitable curvature; It is the direct factor that guarantees that submarine pipeline is laid safely.In order to regulate the curvature of S-shaped stinger used in deepwater to adapt to different laying operating modes, conventionally need to change the PUP PIECE connecting rod of different length.
At present, existing PUP PIECE connecting rod is: bearing pin Placement, that is: first pipe support rack is made to pin shaft hole with the joint that PUP PIECE connecting rod is connected, then, design again the PUP PICEC connecting rod of different length, and design the pin shaft hole that PUP PICEC connecting rod mates with pipe support rack joint, in operation, by bearing pin, with PUP PIECE connecting rod, multistage pipe support rack is connected.
But, because existing pipe support rack joint is when regulating S-shaped stinger used in deepwater curvature, must, by the assistance of hoist, pipe support rack be sling and just can be carried out; And for the laying operating mode that requires different curvature, also need to select the PUP PIECE connecting rod of multiple different lengths, and so that pipe support rack curvature matches with laying operating mode, so, not only increased many workloads, reduced working efficiency; And due to existing PUPPIECE connecting rod, its length is all fixed, can not regulate continuously PUPPIECE length, this makes pipe support rack equipment not possess the continuous regulatory function of curvature.
Model utility content
Main purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and a kind of PUP PIECE connecting rod that can regulate continuously S-shaped stinger used in deepwater curvature is provided, and its needs rotate intermediate sleeve, just the length of holder for regulating pipe support quickly; Not only solved the problem that pipe support rack curvature can not regulate continuously, and without the assistance of hoist, i.e. the curvature of adjustable support pipe support, has reduced the workload that curvature regulates, and has improved working efficiency.
The purpose of this utility model is realized by following technological scheme:
A kind of connection set that can regulate continuously S-shaped stinger used in deepwater curvature, it is characterized in that: be provided with a turnbarrel, the inside of this turnbarrel is provided with a tapped through hole, and the two ends of turnbarrel are respectively provided with the threaded stem that can control the degree of depth in precession turnbarrel.
Described turnbarrel is cylindrical shape.
Described threaded stem is the round thread bar matching with turnbarrel internal thread.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, and its needs rotate intermediate sleeve, just can regulate the length of S-shaped stinger used in deepwater; Not only solved the problem that pipe support rack curvature can not regulate continuously, and without the assistance of hoist, i.e. the curvature of adjustable support pipe support, has reduced the workload that curvature regulates, and has improved working efficiency.
Accompanying drawing explanation:
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is the utility model decomposition texture schematic diagram.
Major label description in figure:
1. turnbarrel, 2. threaded stem.
Embodiment
As Fig. 1, shown in Fig. 2, the utility model is provided with: turnbarrel 1, and the inside of turnbarrel 1 is provided with tapped through hole, and the two ends of turnbarrel 1 adopt thread connecting mode that one threaded stem 2 is respectively installed; By regulating the degree of depth in threaded stem 2 precession turnbarrels 1 to control threaded stem 2, pass in and out the length of rotary drum 2, thereby, the curvature of holder for regulating pipe support.
Above-mentioned turnbarrel 1 is cylindrical shape, and threaded stem 2 is the round thread bar matching with turnbarrel 1 internal thread.
During use, the utility model is arranged on to the hinge place of adjacent two joints: according to the depth of water and the PIPE DIAMETER CALCULATION of laying, the required curvature of pipe support rack, and then calculate the length of required PUPPIECE, and by turnbarrel 1, change the length of PUPPIECE connecting rod, until the length of PUPPIECE connecting rod reaches Len req.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
Claims (3)
1. one kind can regulate the connection set of S-shaped stinger used in deepwater curvature continuously, it is characterized in that: be provided with a turnbarrel, the inside of this turnbarrel is provided with a tapped through hole, and the two ends of turnbarrel are respectively provided with the threaded stem that can control the degree of depth in precession turnbarrel.
2. the connection set that can regulate continuously S-shaped stinger used in deepwater curvature according to claim 1, is characterized in that: described turnbarrel is cylindrical shape.
