Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction, in particular to an auxiliary tool for pipeline joint operation. Background Art

[0002] Pipeline butt jointing is a key step in the construction and maintenance of natural gas pipelines. It requires high-precision alignment and stable fixation to ensure the quality of subsequent operations such as welding. The common practice is to use simple brackets or manual adjustments, which are not only time-consuming and labor-intensive, but also difficult to ensure the accuracy and stability of pipeline butt jointing, especially in complex or narrow working environments. In addition, for large-diameter or special-material pipelines, traditional methods often cannot meet the requirements of butt jointing, resulting in low construction efficiency and increased safety risks.

[0003] First, traditional tools may not be ideal in terms of stability. When performing pipe docking, the stability of the tool is crucial to ensure the accuracy of the pipe position and the tightness after welding. If the tool is not positioned stably on the pipe, it may cause inaccurate pipe docking and affect the welding quality.

[0004] Secondly, operational complexity is also an important issue. Traditional auxiliary tools may require complex setup and adjustment processes, which not only increases the operation time but also increases the requirements for operator skills. In emergency repairs or harsh environments, operational complexity will increase work difficulty and safety risks.

[0005] In addition, traditional pipe joint assist tools may lack adaptability. Due to the diversity of pipe diameters, materials and working environments, it is difficult for a standardized tool to meet the needs of all situations. This limits the versatility and application range of the tool.

[0006] In view of the above problems, the purpose of the utility model is to provide an improved pipeline joint operation auxiliary tool to solve the shortcomings of traditional tools. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] 1.

[0016] 2.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0031] See also Figure 1-4 As shown, the utility model is an auxiliary tool for pipe joint operation, including a joint body 1. A coaxially arranged pipe wall fixer 2 is arranged at one axial end of the joint body 1. An upper pipe guide 3 is arranged at the other axial end of the joint body 1. The joint body 1 specifically includes two coaxial and parallel circular ring plates 11. The two circular ring plates 11 are connected as a whole by a plurality of fixed connecting plates 12. An internal threaded pipe 13 is fixed to both ends of the two sides of each fixed connecting plate 12. An L-shaped bolt 14 is threadedly connected to each internal threaded pipe 13. The two circular ring plates 11 of the joint body 1 are respectively placed on the two ends of the pipes for the joint operation, and the pipe wall fixer 2 is sleeved on the fixed pipe. The L-shaped bolts 14 corresponding to the same side of the circular plate 11 on one side of the pipe wall fixer 2 are all clamped and fixed on the fixed pipe. The movable pipe to be jointed is placed on the inner side of another circular ring plate 11, and the joint operation is completed after the pipe mouth is adjusted to align the two pipe mouths by adjusting a circle of the L-shaped bolts 14.

[0032] In order to improve the stability of the installation of the main body 1 of the mouthpiece on the pipeline, the utility model is specially provided with a pipe wall fixer 2, and the structure of the pipe wall fixer 2 specifically includes a plurality of first axial rods 21 fixed on the side of the circular ring plate 11, and the plurality of first axial rods 21 are evenly arranged along the circular ring plate 11. A circular ring plate connecting frame 22 is fixed to the free ends of the plurality of first axial rods 21. A threaded through hole 23 pointing to the axis of the circular ring plate 11 is provided at the center of the first axial rod 21. A handwheel screw 25 is threadedly connected to the threaded through hole 23. Two guide through holes 24 pointing to the axis of the circular ring plate 11 are symmetrically provided on both sides of the threaded through hole 23 on the first axial rod 21. A pipe wall clamping portion 26 is installed through the two guide through holes 24. The pipe wall clamping portion 26 includes a semicircular tube 261, and the end face of the arc of the semicircular tube 261 is set as a cylindrical surface. Two guide columns 262 respectively matched with the two guide through holes 24 are fixed to the top of the outer arc surface of the semicircular tube 261. A threaded head 263 is fixed to the end of the guide column 262. A nut 264 is threadedly connected to the threaded head 263.

[0033] The pipe wall fixture 2 is tightly combined with the outer wall of the pipe by a circle of pipe wall clamping parts 26 under the jacking action of the handwheel screw 25, and the connection state is stable. The main body 1 of the adapter is connected to the pipe wall fixture 2, and the overall bearing capacity is improved, which effectively ensures the stability of the position of the main body 1 of the adapter when the pipes are docked. In addition, the pipe wall fixture 2 is in contact with the outer wall of the pipe using a circle of evenly distributed pipe wall clamping parts 26, in which the cylindrical surface of the arc of the semicircular tube 261 is in contact with the pipe, and the contact part is two lines. Combined with its structure, the two contact lines are parallel to the axis of the pipe, which in turn ensures that the axis of the pipe wall fixture 2 and the axis of the adapter main body 1 are flush with the axis of the pipe. When the pipe connection end face is perpendicular to its axis, it effectively assists in making the joint gap at the pipe joint uniform.

[0034] In order to facilitate the docking operation of the pipeline, the utility model is specially provided with an upper pipe guide 3, and the structure of the upper pipe guide 3 specifically includes a plurality of second axial rods 31 fixed on the side of another circular ring plate 11, and the plurality of second axial rods 31 are evenly distributed in the lower half of the circular ring plate 11. The outer walls of the plurality of second axial rods 31 are connected as a whole through at least two semicircular ring frames 32. The inner side wall of the second axial rod 31 is provided with a roller mounting groove 33. A roller 34 is installed in the roller mounting groove 33.

[0035] When installing a new pipe joint, first use a crane to put one end of the pipe on the upper pipe guide 3, and then use a sling to lift the other end of the pipe. The outer wall of the pipe of the upper pipe guide 3 is in contact with the roller 34. By moving the lifting end of the pipe, the movement of the pipe connection end relative to the main body 1 of the joint can be easily adjusted. After the two pipe end faces are aligned, the two pipes can be aligned by adjusting a circle of L-shaped bolts 14. After tightening all L-shaped bolts 14, the next step of welding can be carried out.
