Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline construction technical field, especially applicable to the accurate blanking and trepanning operation when the non -plane surface and pipeline connect, concretely be a kind of bidirectional shape taking device of non -plane surface and pipeline connection. BACKGROUND

[0002] During pipeline construction, due to the process requirement of branching or merging of the pipeline, especially the lower pressure branch pipe connected by non-pipe fittings, and the welding type pipe support at the bottom elbow of the vertical pipeline, etc., the surface of the pipeline is curved, which increases the construction difficulty. Usually, blanking software or manual calculation is used for blanking prefabrication. However, due to the deviation of part of the actual data of the pipeline (the density, weight, etc. are also estimated data, which has deviation), it is easy to cause deviation in software or manual calculation. According to the previous actual operation experience, there is indeed a large deviation, and the blanking end cannot be attached to the main pipe.

[0003] In addition, the pipeline is rigid and heavy, and must be blanked twice or more times, which cannot guarantee the proper connection of the final connection. Finally, it will be welded in the state of "almost attached", which not only wastes pipe materials and time, but also affects the appearance and quality of the weld. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a kind of bidirectional shape taking device of non -plane surface and pipeline connection to solve the technical problems that branch pipe and main pipe are not attached accurately, resulting in poor welding quality and low efficiency.

[0009] Further, at least one limiting thin column is perpendicular to the circular cross section of the shape taking segment and is fixed to the outer wall of the shape taking segment as a limiting reference.

[0010] Further, the length of the shape taking segment is 150-180mm.

[0011] Further, the diameter of the thin column is in the range of 3.2-4.0mm.

[0012] Further, the thin column is made of a welding rod after removing the coating.

[0022] In order to make those skilled in the art better understand the utility model, the utility model is further clearly and completely explained in combination with reference drawings and examples. It should be noted that the features in the embodiments and examples in the present application can be combined with each other without conflict.

[0023] A typical embodiment of the utility model provides a bidirectional shape taking device for connecting the non-planar surface and the pipeline, as shown in Figure 1 It includes shape taking short section 3 and multiple slender columns 4.

[0024] Shape taking short section is same specification with branch pipe 2, for simulating actual size and trend of branch pipe.

[0025] Multiple thin posts 4 are evenly distributed on the surface of the shaped short section 3 and are circumferentially fixed by binding members 6. The thin posts 4 can fall along the surface of the main pipe 1 and mark the opening area. Optionally, the binding member is a rubber band or an adjustable strap.

[0026] In this embodiment, a shaped short section 3 of the same specification as the branch pipe 2 is used as a carrier, and thin columns 4 are distributed all over the surface of the shaped short section 3 by binding members 6. Based on the direction of the branch pipe 2 and the angle between it and the main pipe 1, such as... Figure 3 As shown, this device is used to place and move the pipe 1 at the actual opening position according to the drawing until the final position is determined. At the same time, the front end of the thin column 4 on the shaping short section 3 falls down to the surface of the pipe 1 along the shaping short section 3. At this time, the opening area on the pipe 1 can be drawn with a stone pencil.

[0027] After marking, pick up the shape picker, as follows: Figure 4 As shown, insert the branch pipe to be prefabricated into the front end of the shaping short section 3, and draw a full circle mark on the branch pipe 2 according to the current state of the thin column 4.

[0028] After the branch pipe end is cut, it is checked again at the hole mark of the main pipe 1, the mark is re-marked, and the edge of the hole is polished and finely adjusted to ensure that the hole size of the main pipe 1 is more accurate.

[0029] In a preferred embodiment, such as Figure 2 As shown, in order to ensure that the thin column 4 remains parallel to the central axis of the attached pipe during the pushing and falling process, a limiting thin column 5 can be spot-welded and fixed as a reference limit, which greatly ensures that the entire circle of thin columns 4 does not deviate.

[0030] The following specific embodiments provide a clearer and more complete description of the technical solution claimed by this utility model.

[0031] The solution provided in this embodiment is mainly used for the installation of pipe supports under non-pressurized pipe branches, air ducts, and elbows where pressure requirements are low.

[0032] First, select a shaping short section 3 of the same specification as branch pipe 2. Pipes with lengths of 150mm, 160mm, 170mm, and 180mm can be used as shaping short sections 3. First, fix a limiting thin column 5 perpendicular to the diameter of the circular cross section of shaping short section 3 on the surface of shaping short section 3. The materials of limiting thin columns 4 and 5 should all be of equal length and straight, and have a certain rigidity. It is recommended to use failed welding rods, clean the surface coating, and select 3.2mm or 4.0mm welding rods according to the diameter of branch pipe.

[0033] The embodiment takes the vertical connection of branch pipe 2 to main pipe 1 as an example (the angle branch pipe operation mode is the same), first selects a section of the same shaped short section 3 according to the specification of branch pipe 2. The field failure welding rod is used, and after the coating is removed, a thin column 4 is used as a shaping column, and the shaped short section 3 is combined to form a shaper by means of strong rubber bands or adjustable straps. In order to ensure that the thin column 4 does not twist and deviate as a whole, a limiting thin column 5 is first spot welded and fixed for limiting use.

[0034] According to the requirements of the drawings, the shaper is fitted with the main pipe 1 according to the position and angle of the branch pipe 2, and the thin column 4 is completely dropped to the surface of the main pipe 1. A stone pen or a marker is used to mark the opening size on the surface of the main pipe 1. After the marking is completed, the shaper is removed, and then it is sleeved into the pipe opening position of the branch pipe 2 to mark the cutting line. During this process, the fixing strength of the thin column 4 of the shaper should be ensured, and the displacement of the thin column 4 during the transfer and sleeving process should be ensured.

[0035] After the opening and cutting according to the two markings are completed, the polishing and correction of the interface before welding can be performed. This process is mainly aimed at the connection mode of the branch pipe 2 and the main pipe 1. After appropriate treatment of the respective connection ports according to different modes (installation type or insertion type), the welding operation can be performed.

[0036] The shaper provided by the utility model can be used for the connection of the main pipe 1 and the pipe bracket at the branch pipe, elbow and other special-shaped surfaces.

[0037] The embodiment has been applied to the natural gas pipeline construction process of the four wells in the field of the Turkish underground natural gas storage project. A bottom support leg for a bend pipe needs to be arranged at the 90° elbow close to the ground of a section of vertical pipeline connected to a wellhead. The connection between the support leg and the elbow is in a full welding form. In order to ensure that the utility and aesthetics coexist after welding is completed, it is required that the support leg and the elbow connection are completely fitted. The shaper provided by the utility model can ensure that the welding gap is the same, and then the welding strength and aesthetics are ensured.

[0038] The scope of protection required by the utility model is not limited to the above specific embodiments. For those skilled in the art, the utility model can have various modifications and changes. Any modification, improvement and equivalent replacement made within the concept and principle of the utility model should be included in the protection scope of the utility model.
