Abstract
The utility model provides a be used for aboral instrument of long distance pipeline welding, is applicable to the welding that is geared to the needs of the job of long distance pipeline, and it includes jack, characterized by jack and rectangle frame and the cooperation of ring clamp utensil, the length of rectangle frame is 220mm, and the width is 400mm, and a long edge of rectangle frame is equipped with the nut, ring clamp utensil is formed through bolted splice by two semi -circular fasteners, semi -circular fastener adopts two square steel to bend to two and half circular member, and two and half circular member are parallel, are formed by connecting through a plurality of connection square steel between two and half circular member. The utility model discloses be geared to the needs of the job welding construction with traditional manual work and compare, construction convenience, not only guaranteed the aboral degree of accuracy of steel pipe but also guaranteed that the welded is convenient afterwards to the installation effectiveness is greatly improved.
Description
Technical field
The utility model is applicable to the instrument for counterpart when long distance pipeline welds, and is specially adapted to the construction of large diameter long distance pipeline welding counterpart.
Background technology
Along with the fast development of China's economy, China is increasing for the demand of the energy, and the energy resource supply of our country mainly relies on coal.But the harm caused environment in process due to coal is very large, especially very serious to the pollution of air.The haze weather that recent years, Beijing-Tianjin area occurred is exactly illustration.So this Ji Nian China proposes become the energy development mode that defeated coal is gas transmission.Remove a large amount of boilers in city, pulled out a large amount of chimneys, in the coal production ground engineering projects such as large quantities of coal gases, coal liquifaction that started.And these oil gentle all needs adopts long distance pipeline to be transported in city.Therefore there is the engineering project of many long-distance transport pipes in China in construction.Focal point and difficult point in long-distance transport pipes construction is the butt welding construction of pipeline.Require in construction that counterpart is rapidly, accurately, and convenient welder's operation subsequently.Common way is that crane lifting coordinates artificial spot welding counterpart.The counterpart time is long, and precision is not high.
Summary of the invention
Both ensure pipeline butt speed and precision to reach, can ensure again welder's operation subsequently, the utility model provides the one that can improve pipeline butt speed and precision for pipeline aligning tool.
The utility model comprises jack, it is characterized in that jack coordinates with rectangular frame and annular fixture; The length of described rectangular frame is 220mm, and width is 400mm, and a nut is welded on a long limit of rectangular frame; Described annular fixture is formed by bolted splice by two semicircle fasteners, and described semicircle fastener adopts two square steel to bend to two semi-circular piece, and two semi-circular piece are parallel, is formed by connecting between two semi-circular piece by some connection square steel.
The internal diameter of described annular fixture is identical with by the external diameter of organizing right long distance pipeline.
The utility model had both ensured pipeline butt speed and precision, can ensure again welder's operation subsequently, time saving and energy saving, substantially increased operating efficiency again.It can not only complete pipeline butt faster, and can ensure the construction quality of pipeline butt, and construction cost is low, and construction speed is accelerated greatly.

Detailed description of the invention
Embodiment: shown in Fig. 1, Fig. 2, Fig. 3, the present embodiment preparation method is:
1, respectively two square steel are bent to two square steel circles, two square steel circles be arranged in parallel and spacing is 160mm;
2, with some square steel 2 two square steel lap weldings are connect and be fixed into an annular framework;
3, annular framework is divided into two cuts into two semicircular frame 1;
4, by hinged for one end of two semicircular frame and connect with bolt 3;
The specification of square steel is the square steel of 20 × 20mm, and the bolt of connection adopts the bolt of Φ 20.Be used for coordinating jack clamping steel pipe with the rectangle frame that the round steel of Φ 20mm is made.
Shown in Fig. 4, the length of rectangle frame is 220mm, and width is 400mm, and a long limit of rectangle frame is provided with the nut 4 of Φ 25mm.
Using method of the present utility model:
1, rectangle frame is extend into need welding two pipelines docking port in (rectangle frame is positioned at the docking port Position Pipe of two pipelines, and rectangle frame rides on two pipelines);
2, will the docking port of two pipelines of welding be needed to aim at;
3, by the docking port place of annular fixture chuck at two pipelines, and pipeline is clamped;
4, with jack, rectangle frame is held out against;
5, the docking port of two pipelines is welded.
