Abstract
A radiation protection device for carrying out radiographic testing on a submarine pipeline girth joint is provided with a supporting pipe, a lead protection layer connected to the inner wall of the supporting pipe, a plurality of supporting gaskets arranged on the lead protection layer and carrying handles arranged on the two sides of the supporting pipe. The supporting pipe is formed by two semicircular pipes and a plurality hinges in a connecting mode, and the hinges are arranged on the outer wall of one side of the supporting pipe. A locking-closing hook is arranged on the outer wall of the other side of the supporting pipe. A plurality of lifting lugs are arranged on the outer wall of the supporting pipe. When the radiation protection device carries out radiographic testing on the submarine pipeline girth joint, the problem that rays cause damage to a human body is solved, effective protection from rays during a submarine pipeline paving process is achieved, ray working can be achieved out of the range of four meters, ray radiation dose is smaller than the national standard of non-working personnel dose rate, namely 1.5 muSv (X-ray), and meanwhile the detecting efficiency of a submarine pipeline butt welding joint and the paving efficiency of a submarine pipeline are improved.
Description
Technical field
The utility model relates to the protective device of ray, relates in particular to a kind of for subsea pipeline girth joint being carried out to the radiation protector of ray detection.Belong to Offshore Engineering field.
Background technology
In subsea pipeline process of deployment, for the detection of subsea pipeline butt-weld, generally adopt ray crawl device to carry out weld seam detection, in order to prevent the infringement of ray to human body, operating personnel need to detect in plumbous room at special anti-ray.Due to the limited space of pipe laying ship deck, and laying work line is other without fixed plumbous room, if use the plumbous room of large-scale mobile, and not only ship reconstruction difficulty, and cost is huge; And, because the plumbous room of large-scale mobile moves slowly, will greatly increase the activity duration of the detection to subsea pipeline butt-weld, affect the laying efficiency of subsea pipeline.
Utility model content
Fundamental purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of radiation protector that subsea pipeline girth joint is carried out to ray detection, it is carrying out subsea pipeline girth joint in the process of ray detection, not only solve ray to the hurtful problem of human body, realized the effective protection to ray in pipe laying process; And, can also make ray operation beyond 4 meters of scopes, x radiation x dose rate is less than the national standard of inoperative personnel dose rate; Meanwhile, detection efficiency to subsea pipeline butt-weld and the laying efficiency of subsea pipeline have been improved.
The purpose of this utility model is realized by following technical scheme:
A kind of radiation protector that subsea pipeline girth joint is carried out to ray detection, it is characterized in that: be provided with: a stay pipe, be connected to the lead protection layer of stay pipe inwall, be arranged on several support pad on lead protection layer, be arranged on the carrying handle of stay pipe both sides.
Described stay pipe is to be connected and composed by two semi-circular tubes and the several hinged hinge that is arranged on stay pipe one side outer wall; One locking hook is installed on the opposite side outer wall of stay pipe; Several lifting hangers are also installed on the outer wall of stay pipe.
Described support pad is symmetrically distributed in subsea pipeline girth joint both sides.
Described several hinged hinges interval 90 degree are positioned on stay pipe center line, and hinged hinge symmetria bilateralis is distributed with carrying handle; And lifting hanger and hinged hinge interval 90 are spent, and with carrying handle be on an axis.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it is carrying out subsea pipeline girth joint in the process of ray detection, not only solve ray to the hurtful problem of human body, realized the effective protection to ray in pipe laying process; And, can also make ray operation beyond 4 meters of scopes, x radiation x dose rate is less than the national standard of inoperative personnel dose rate: 1.5 μ Sv (X ray); Meanwhile, detection efficiency to subsea pipeline butt-weld and the laying efficiency of subsea pipeline have been improved.

1. support pad, 2. stay pipe, 3. lead protection layer, 4. carrying handle, 5. hinged hinge, 6. locking hook, 7. lifting hanger.
Embodiment
As Fig. 1, shown in Fig. 2, the utility model is provided with: a stay pipe 2, employing riveting method are connected to the lead protection layer 3 of stay pipe 2 inwalls, mode with bolts is arranged on the several support pad 1 on lead protection layer 3, the carrying handle 4 that employing welding manner is arranged on stay pipe 2 both sides, wherein, on the outer wall of stay pipe 2, adopt welding manner that several lifting hangers 7 are installed, by lifting hanger 7 is connected with loop wheel machine, realize installation of the present utility model.
Above-mentioned stay pipe 2 is to be connected and composed by two semi-circular tubes and the several hinged hinge 5 that is arranged on stay pipe 2 one side outer walls, and the hinged hinge 5 of the present embodiment is 3, equidistant being connected on stay pipe 2.
One locking hook 6 is also installed on the opposite side outer wall of stay pipe 2, and as protective device, after preventing that stay pipe 2 from fastening, stay pipe 2 is unexpected to be opened.
The present embodiment: stay pipe 2 length are: 600mm, diameter is: Φ 219mm, wall thickness is: 11mm; Lead protection layer 3 thickness are: 3mm; Support pad 1 arc for matching with stay pipe 2 inwalls, adopts aluminum alloy material, and its length is: 200mm, is widely: 10mm, and thickness is: 11mm; For supported pipe 2, make lead protection layer 3 and protection face of weld there is certain distance, in order to avoid radiographic film is caused to damage.
As shown in Figure 2, support pad 1 is symmetrically distributed in subsea pipeline girth joint both sides; Carrying handle 4 is symmetrically distributed in hinged hinge 5 both sides, and several hinged hinge 5 intervals 90 are spent, and are positioned on stay pipe 2 center lines; Lifting hanger 7 is two, and itself and hinged hinge 5 intervals 90 are spent, and with carrying handle 4 be on an axis, by lifting hawser with hang loop wheel machine be connected.
The utility model principle of work: when use, lifting hanger 7 is connected by hawser with suspension loop wheel machine, after film has been pasted, by loop wheel machine, the utility model is moved on weld seam, make support pad 1 be symmetrically placed in weld seam both sides, and stablize the utility model by carrying handle 4, after the utility model is placed in protection weld seam, pin locking hook 6, start ray operation, after ray operation completes, open locking hook 6, start loop wheel machine, remove the utility model.
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.
