Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance, and more specifically, it relates to a fixing device for oil and gas pipeline maintenance. Background Technology

[0002] Oil and natural gas are very common and frequently used in people's lives. The use of fossil fuels such as oil and natural gas has greatly facilitated people's lives. When oil and natural gas are transported over long distances, they are often transported through oil and gas pipelines. When oil and gas pipelines are damaged, they need to be replaced or repaired. During the repair process, fixing devices are needed to secure the pipeline. Therefore, fixing devices are needed to secure the pipeline to prevent it from moving during the repair process and causing injury to the repair personnel. However, the existing fixing devices can only fix the pipeline. When workers need to find the damaged part or inspect the pipeline, they cannot rotate the pipeline, which makes it less convenient for workers to use. Moreover, when repairing pipelines, it is often necessary to lift the pipeline to a certain height. Due to the weight of the pipeline, it is inconvenient to lift the pipeline, thus affecting the pipeline repair. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a fixing device for oil and gas pipeline maintenance, which has the following advantages:

[0017] 1. This utility model, by setting up a fixing structure and a support structure, allows one end of the pipe to be inserted into the fixing ring when the pipe is fixed to the fixing structure. Rotating the first adjusting rod causes the fixing block to move through the rotational connection between the first adjusting rod and the fixing block, as well as the threaded connection between the first adjusting rod and the fixing frame. This, in turn, fixes one end of the pipe through the cooperation of multiple fixing blocks. After one end of the pipe is fixed, the first threaded rod is rotated according to the length of the pipe. The position of the support frame is adjusted through the threaded connection between the first threaded rod and the support frame. Rotating the second adjusting rod adjusts the height of the support plate through the threaded connection between the second adjusting rod and the support frame, thereby supporting one end of the pipe and facilitating the fixing and stability of the pipe.

[0018] 2. This utility model features a rotatable connection between a connecting frame on a fixed ring and an extension plate. When inspecting a pipeline or locating a damaged area, a first motor drives a rotating column to rotate, which in turn drives the fixed ring to rotate, causing the pipeline to rotate. After locating the damaged area, when repairing the pipeline, the second threaded rod is rotated. Through the two oppositely oriented threads on the second threaded rod and their cooperation with the clamping block, the clamping block is moved to clamp the pipeline, thereby fixing the pipeline in the desired direction and facilitating pipeline maintenance.

[0019] 3. This utility model connects the main frame and the mounting frame via an electric push rod. When the pipe needs to be placed on the mounting frame, the extension of the electric push rod causes the mounting frame to descend, facilitating the placement of the pipe. After placement, the retraction of the electric push rod causes the mounting frame and the pipe to rise, facilitating the raising of the pipe to a certain height, thereby facilitating the inspection and maintenance of the pipe.

The mounting frame 2 is provided with a clamping block 13, and the second threaded rod 12 passes through the clamping block 13 and is threadedly connected to the clamping block 13.

[0031] In this embodiment, the main body frame 1 and the mounting frame 2 together constitute the main structure of the entire fixing device.

[0032] More specifically, the pipes are fixed by a fixed structure and supported by a supporting structure.

[0033] Please see Figures 1-5As one method of pipe fixing: a connecting block 14 is fixedly installed on the side of the mounting bracket 2, and an electric push rod 15 is fixedly installed on the mounting bracket 2. The connecting block 14 has a mounting hole 16, which cooperates with the moving end of the electric push rod 15. A support plate 17 is detachably installed at the front end of the electric push rod 15. Multiple support plates 17 are provided. The moving end of the electric push rod 15 is threaded. The inner wall of the support plate 17 is threaded. The support plate 17 and the electric push rod 15 are threadedly connected. Multiple fixing blocks 4 and first adjusting rods 5 are provided. The fixing blocks 4 pass through the fixing ring 3. The first adjusting rods 5 are rotatably installed on the fixing blocks 4. A rotating hole 18 is provided on the extension plate. A connecting bracket 19 is fixedly installed at the rear end of the fixing ring 3. A rotating column 20 is fixedly installed on the connecting bracket 19. The rotating column 20 and the rotating hole 18 are connected. The components 8 are mutually coordinated. The rotating column 20 is rotatably connected to the rotating hole 18. The first motor 21 is fixedly installed on the extension plate. The output end of the first motor 21 is fixedly connected to the rotating column 20. The side end of the fixed ring 3 is fixedly installed with a fixed frame 22. Multiple fixed frames 22 are provided. The first adjusting rod 5 passes through the fixed frame 22. The surface of the first adjusting rod 5 is provided with threads. The first adjusting rod 5 is threadedly connected to the fixed frame 22.

The first threaded rod 7 is rotatably connected to the mounting frame 2. The second adjusting rod 23 is rotatably installed on the support plate 9. The second adjusting rod 23 passes through the support frame 8. The second adjusting rod 23 is threadedly connected to the support frame 8. The first threaded rod 7 passes through the support frame 8. The first threaded rod 7 is threadedly connected to the support frame 8.

[0034] Specifically, when fixing the pipe to the fixed structure, one end of the pipe is inserted into the fixing ring 3. The first adjusting rod 5 is rotated, and the fixing block 4 is moved through the rotational connection between the first adjusting rod 5 and the fixing block 4 and the threaded connection with the fixing frame 22. Thus, the fixing block 4 is fixed through the cooperation of multiple fixing blocks 4. After the fixing of one end of the pipe is completed, the first threaded rod 7 is rotated according to the length of the pipe. The position of the support frame 8 is adjusted through the threaded connection between the first threaded rod 7 and the support frame 8. The second adjusting rod 23 is rotated, and the height of the support plate 9 is adjusted through the threaded connection between the second adjusting rod 23 and the support frame 8. Thus, the pipe end is supported. When inspecting the pipe or finding the damaged part, the first motor 21 drives the rotating column 20 to rotate, which drives the fixing ring 3 to rotate, thereby rotating the pipe. After finding the damaged part, when repairing the pipe, the second threaded rod 12 is rotated. Through the two opposite threads on the second threaded rod 12 and the cooperation with the clamping block 13, the clamping block 13 is moved to clamp the pipe, thereby fixing the pipe and making it easy to fix the pipe in the required direction.

[0035] In summary, when using it as a whole:

[0036] When the pipe is fixed to the fixed structure, the extension of the electric push rod 15 causes the mounting bracket 2 to descend, inserting one end of the pipe into the fixing ring 3. The first adjusting rod 5 is rotated, and through the rotational connection between the first adjusting rod 5 and the fixing block 4 and the threaded connection between the first adjusting rod 5 and the fixing bracket 22, the fixing block 4 is moved, thereby fixing one end of the pipe through the cooperation of multiple fixing blocks 4. After one end of the pipe is fixed, the first threaded rod 7 is rotated according to the length of the pipe, and the position of the support bracket 8 is adjusted through the threaded connection between the first threaded rod 7 and the support bracket 8. The second adjusting rod 23 is rotated, and the height of the support plate 9 is adjusted through the threaded connection between the second adjusting rod 23 and the support bracket 8, thereby supporting one end of the pipe.

[0037] When inspecting the pipeline or locating the damaged part, the first motor 21 drives the rotating column 20 to rotate, which in turn drives the fixed ring 3 to rotate, thus rotating the pipeline. After locating the damaged location, when repairing the pipeline, the second threaded rod 12 is rotated. Through the two threads with opposite directions on the second threaded rod 12 and their cooperation with the clamping block 13, the clamping block 13 is moved to clamp the pipeline, thereby fixing the pipeline and making it easy to fix the pipeline in the required direction.
