Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, and in particular to a pipeline maintenance positioning auxiliary component. Background Technology

[0002] When inspecting pipelines, it is necessary to align and position the two pipelines. Alignment ensures a tight fit at flanges, threads, or other connections, reducing the possibility of leakage. Generally, the two pipelines need to be coaxially fixed to ensure complete alignment. When connecting two pipelines, the two ends of the component need to be fixed to the two pipelines respectively, which can obstruct the connection point and make it difficult to inspect the connection. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the connection between two pipes is blocked by components, making it inconvenient to inspect the connection. Therefore, this invention proposes a pipe inspection and positioning auxiliary component.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a pipeline maintenance positioning auxiliary component, including two fixed rings, each with a T-shaped groove on its inner side, and two T-shaped sliders slidably disposed in each T-shaped groove. A connecting plate is fixedly connected between the two opposing T-shaped sliders, and a coaxial positioning mechanism is provided on each of the two fixed rings.

[0006] Preferably, the coaxial positioning mechanism includes multiple through holes. Multiple through holes are equally spaced around the circumference of the fixed ring. Each of the multiple through holes is provided with a movable rod. One end of each of the multiple movable rods is fixedly connected to an abutment block, and the other end is abutted by an abutment mechanism.

[0007] Preferably, a fixing part is fixedly connected between the two connecting plates.

[0008] Preferably, the abutting mechanism includes a movable ring, which is sleeved on the fixed ring. Multiple connecting parts are fixedly connected at equal intervals around the circumference of the movable ring. Each of the multiple connecting parts is fixedly connected to a telescopic rod. The multiple telescopic rods are fixedly connected to the fixed ring. The inner wall of the movable ring is provided with an inclined surface.

[0009] Preferably, the movable rod is provided with a roller, and the roller abuts against the inclined surface.

[0010] Preferably, a limiting groove is formed on the inner wall of the through hole, and a limiting strip is slidably disposed in the limiting groove, the limiting strip being fixedly connected to the moving rod.

[0011] Preferably, the abutment block has an arc-shaped structure.

[0012] The present invention proposes a pipeline inspection and positioning auxiliary component, which has the following advantages: the coaxial positioning mechanism is used to fix the fixing ring on the two pipelines respectively. Since the T-shaped slider can slide in the T-shaped groove, it can drive the connecting plate to change its position, exposing different positions at the connection of the two pipelines for inspection and maintenance, and avoiding obstruction.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-3 A pipeline maintenance positioning auxiliary component includes two fixing rings 6. T-shaped grooves 10 are provided on the inner sides of the two fixing rings 6. Two T-shaped sliders 9 are slidably arranged in the two T-shaped grooves 10. A connecting plate 1 is fixedly connected between the two opposing T-shaped sliders 9. A coaxial positioning mechanism is provided on the two fixing rings 6. The coaxial positioning mechanism is used to fix the fixing rings 6 to the two pipelines respectively. Since the T-shaped sliders 9 can slide in the T-shaped grooves 10, they can drive the connecting plate 1 to change position, exposing different positions of the connection between the two pipelines for maintenance and avoiding obstruction.

[0020] The coaxial positioning mechanism includes multiple through holes. Multiple through holes are equally spaced around the circumference of the fixed ring 6. Each through hole contains a movable rod 8. One end of each movable rod 8 is fixedly connected to an abutment block 7, and the other end abuts through an abutment mechanism. The abutment block 7 has an arc-shaped structure.

[0021] A fixing part 2 is fixedly connected between the two connecting plates 1. The fixing part 2 connects the two connecting plates 1 so that the two connecting plates 1 can rotate simultaneously.

[0022] Example 2: Refer to Figure 1-3 In another preferred embodiment of this utility model, based on embodiment 1, the abutting mechanism includes a movable ring 3, which is sleeved on a fixed ring 6. Multiple connecting parts 4 are fixedly connected at equal intervals around the circumference of the movable ring 3. Each connecting part 4 is fixedly connected with a telescopic rod 5, which is a telescopic rod with a self-locking function. The multiple telescopic rods 5 are fixedly connected to the fixed ring 6. An inclined surface 11 is provided on the inner wall of the movable ring 3. The extension of the telescopic rod 5 drives the movable ring 3 to move, causing the inclined surface 11 to push the roller 12 towards the axis of the fixed ring 6, thus causing the abutting block 7 to abut against the pipe, thereby fixing the fixed ring 6 onto the pipe for positioning and alignment of pipes of different sizes. When it is necessary to release the fixation, the telescopic rod 5 retracts, driving the movable ring 3 to move, releasing the abutment of the inclined surface 11 against the roller 12, thereby releasing the abutment fixation of the abutting block 7 against the pipe.

[0023] The movable rod 8 is equipped with a roller 12, which abuts against the inclined surface 11. The friction between the roller 12 and the inclined surface 11 is rolling friction, which helps to reduce frictional resistance.

[0024] Example 3: Reference Figure 1-4 As another preferred embodiment of this utility model, based on embodiment 2, a limiting groove is provided on the inner wall of the through hole, and a limiting strip 13 is slidably arranged in the limiting groove. The limiting strip 13 is fixedly connected to the moving rod 8. By using the limiting strip 13 and the limiting groove to limit the moving rod 8, the moving rod 8 is prevented from rotating, thereby avoiding the situation where the abutment block 7 and the roller 12 rotate. The diameter of the roller 12 is larger than the inner diameter of the through hole, which helps to prevent the moving rod 8 from detaching from the through hole and avoids the situation of loss.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
