Description

Technical Field

[0001] This utility model belongs to the technical field of socket weld pipe fitting assembly, and particularly relates to an auxiliary device for socket weld pipe fitting assembly. Background Technology

[0002] When assembling socket weld pipe fittings, relevant standards and specifications must be strictly followed. First, the socket and spigot of the fittings must be carefully cleaned to remove oil, rust, and other impurities, ensuring the cleanliness of the welding surfaces. During assembly, the insertion depth of the fittings must meet the requirements to ensure the connection strength after welding. When welding, appropriate welding processes and materials must be selected, and parameters such as welding current, voltage, and welding speed must be controlled. After welding, visual inspection and non-destructive testing, such as flaw detection, are required to check for welding defects such as porosity and cracks. Only socket weld pipe fittings that pass the inspection can be put into use, thereby ensuring the safe and stable operation of the entire pipeline system.

[0003] In the construction of offshore oil engineering projects, the fabrication and installation of process pipelines of 2 inches and below account for a considerable amount of workload. Most of these pipelines are welded using the socket welding process. The efficiency of socket welding pipeline prefabrication directly affects the project's construction progress and cost. Reasonably controlling the assembly gap between socket welding pipe fittings is one of the key factors to ensure welding quality.

[0004] If the gap between the assembly parts is too large, it will cause the water flow inside the pipe to scour more intensely, thus leading to pipe corrosion; while if the gap is too small, the weld may crack due to excessive expansion of the pipe when heated. Therefore, in order to ensure the quality of the pipe, the gap between the assembly parts must be controlled within a reasonable range. Utility Model Content

[0032] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0033] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Please see Figures 1 to 6 This utility model provides an auxiliary device for assembling socket weld pipe fittings, including a bearing shell 1; a first bearing frame 2 is installed on the back of the bearing shell 1, and an auxiliary component is installed in the first bearing frame 2 and the bearing shell 1; an assembly pipe fitting 3 is installed on the auxiliary component; a socket weld pipe fitting 4 is installed on one side of the assembly pipe fitting 3, and a measuring element is installed on the auxiliary component.

[0035] Using the above scheme: When installing the socket weld pipe fittings, the worker first places the assembled pipe fitting 3 on one side of the bearing shell 1, then uses the auxiliary component to clamp the assembled pipe fitting 3, and then inserts the assembled pipe fitting 3 into the bottom of the socket pipe fitting 4 to make the two align. During the insertion process, the measuring component is used to detect the gap between the assembled pipe fitting 3 and the socket pipe fitting 4. In this way, the gap can be controlled within a certain range, further improving the fit quality of the assembled pipe fitting 3 and the socket pipe fitting 4.

[0036] Furthermore, the auxiliary component includes two first rotating shafts 5 rotatably connected within the bearing housing 1; each of the first rotating shafts 5 is equipped with an incomplete gear 6, one side of which is engaged with a toothed plate 7; a clamping plate 8 is installed on the back of the toothed plate 7, which contacts the outer wall of the assembled pipe fitting 3.

[0037] Furthermore, a drive plate 9 is slidably connected inside the bearing shell 1; one side of the drive plate 9 extends through the bearing shell 1, and a first connecting plate 10 is rotatably connected between the two sides of the drive plate 9 and the incomplete gear 6.

[0038] Furthermore, a first slider 11 is slidably connected inside the first support frame 2; the back of the first slider 11 is fixedly connected to the drive plate 9, a threaded sleeve 12 is installed on the first slider 11, and a first threaded rod 13 is rotatably connected to the first support frame 2; one end of the first threaded rod 13 is threadedly connected to the threaded sleeve 12, and the other end of the first threaded rod 13 is fixedly connected to the drive disk 14.

[0039] Furthermore, a first fixing frame 15 is installed on the first support frame 2; a first spring 16 is installed on the lower side of the first fixing frame 15, and a limit rod 17 is inserted into the side of the first threaded rod 13 near the drive disk 14; one side of the first spring 16 is fixedly connected to the limit rod 17.

[0040] The above scheme is adopted as follows: In use, the rotation of the drive disk 14 drives the first threaded rod 13 to rotate. Since the first threaded rod 13 is threadedly connected to the threaded sleeve 12, when the first threaded rod 13 rotates, it will drive the threaded sleeve 12, thereby causing the first slider 11 to move on the first support frame 2 toward the drive disk 14. The movement of the first slider 11 will pull the drive plate 9 to gradually extend out of the support shell 1, and through the first connecting plate 10, the incomplete gear 6 will rotate. The incomplete gear 6 and the toothed plate 7 mesh with each other, driving the toothed plate 7 and the clamping plate 8 on it to move, thereby clamping the assembled pipe fitting 3 and assisting its installation into the socket pipe fitting 4. After the assembled pipe fitting 3 is clamped, the compressed first spring 16 pushes the limiting rod 17 to move downward. The limiting rod 17 is inserted into the first threaded rod 13 to fix the first threaded rod 13 and prevent the clamping plate 8 from moving.

[0041] It should be noted that: since a limiting plate is installed on the top of the limiting rod 17, and this limiting plate is attached to the top of the first fixing frame 15, when the limiting rod 17 is not needed to be inserted into the first threaded rod 13, the limiting rod 17 is fixed by bolt 21.

[0042] Furthermore, the measuring element includes a first fixing block 18 mounted on one of the clamping plates 8, and a second threaded rod 19 is threadedly connected to the first fixing block 18; the free end of the second threaded rod 19 is attached to the end of the socket fitting 4.

[0043] Furthermore, a scale 20 is installed on the first fixing block 18, and the scale 20 is connected to the first fixing block 18 by bolts 21.

[0044] Using the above scheme: When in use, after the assembled pipe fitting 3 is clamped, the pipe fitting 3 to be assembled is inserted into the bottom of the socket pipe fitting 4. Then, the free end of the second threaded rod 19 abuts against the end face of the socket pipe fitting 4. By rotating the second threaded rod 19 and simultaneously pushing the socket pipe fitting 4 to move, the length of rotation of the second threaded rod 19 is adjusted to the assembly gap of the socket weld pipe fitting.

[0045] It should be noted that the scale plate can be installed on the first fixed block 18 using bolt 21, and then the rotation length of the second threaded rod 19 can be measured using the scale plate.

[0046] The working principle of this utility model:

[0047] During the assembly and installation of socket weld pipe fittings, the workers first place the assembled pipe fittings 3 on one side of the bearing shell 1. The rotation of the drive disc 14 drives the first threaded rod 13 to rotate. Since the first threaded rod 13 is threadedly connected to the threaded sleeve 12, when the first threaded rod 13 rotates, it drives the threaded sleeve 12, which in turn causes the first slider 11 to move on the first bearing frame 2 toward the drive disc 14. The movement of the first slider 11 pulls the drive plate 9 to gradually extend out of the bearing shell 1, and through the first connecting plate 10, it causes the incomplete gear 6 to rotate. The incomplete gear 6 meshes with the toothed plate 7, driving the toothed plate 7 and its clamps. The plate 8 moves to clamp the assembled pipe fitting 3 and assist it in being installed into the socket pipe fitting 4. After the assembled pipe fitting 3 is clamped, the compressed first spring 16 pushes the limiting rod 17 downward. The limiting rod 17 is inserted into the first threaded rod 13 to fix the first threaded rod 13 and prevent the clamping plate 8 from moving. After the assembled pipe fitting 3 is clamped, the pipe fitting 3 to be assembled is then inserted into the bottom of the socket pipe fitting 4. Then, the free end of the second threaded rod 19 abuts against the end face of the socket pipe fitting 4. By rotating the second threaded rod 19 and simultaneously pushing the socket pipe fitting 4 to move, the length of rotation of the second threaded rod 19 is the assembly gap of the socket weld pipe fitting.
