[0002] In piping systems, flanges are critical components, and their installation and replacement are frequent. Traditional flange replacement processes face numerous challenges, especially for large flanges used in large pipelines. Installing a new flange requires multiple people working together, consuming significant manpower. Furthermore, due to limited operating space and the flange's weight, installation accuracy is difficult to guarantee, resulting in low efficiency. Simultaneously, accurately aligning the bolt holes and securing the new flange to the existing flange on the pipeline remains a technical hurdle for construction workers. Current technology lacks a convenient, efficient, and labor-cost-reducing flange replacement auxiliary tool; an innovative device is urgently needed to solve these problems. Utility Model Content

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Please see Figure 1 - Figure 5 This utility model provides a technical solution including a positioning ring 1, which adopts a split structure, consisting of two parts: a semi-ring A101 and a semi-ring B102. One end of semi-ring A101 and one end of semi-ring B102 are rotatably connected by a hinge. This connection method allows semi-ring A101 and semi-ring B102 to rotate relative to each other within a certain range, facilitating the installation of the positioning ring 1 around a pipe or flange. A snap-fit ​​mechanism is provided between the other ends of semi-ring A101 and semi-ring B102. This snap-fit ​​mechanism is existing technology, and can employ common quick-connect structures such as latches or pins. Its function is to enable quick engagement between semi-ring A101 and semi-ring B102 after they are placed around the target object (such as a pipe or flange), thereby merging semi-ring A101 and semi-ring B102 to form a complete circular structure.

[0025] The positioning element 4 is structured and installed as follows: Multiple grooves 2 are evenly distributed on the circumferential surface of the positioning ring 1 for mounting the positioning element 4. Each positioning element 4 mainly consists of a positioning rod 41, a connecting rod 42, and a spring element B43. The connecting rod 42 is slidably disposed inside the positioning rod 41 and connected to the positioning rod 41 via the spring element B43. Specifically, the spring element B43 can be a compression spring, one end of which is fixed at a specific position inside the positioning rod 41, and the other end is connected to the connecting rod 42, allowing the connecting rod 42 to maintain its relative position under the action of the spring element B43 when no external force is applied. The end of the connecting rod 42 away from the spring element B43 is machined with external threads for threaded connection with the nut sleeve 5.

[0026] The installation process of the positioning component 4 on the positioning ring 1 is as follows: First, the end of the connecting rod 42 away from the elastic component B43 is passed through the groove 2 of the positioning ring 1. At this time, the groove 2 guides and limits the connecting rod 42. Next, the nut sleeve 5 is screwed onto the end of the connecting rod 42 that exits the groove 2. Through the threaded engagement between the nut sleeve 5 and the connecting rod 42, the initial installation of the positioning component 4 on the positioning ring 1 is achieved. It is worth noting that a stop block A6 is provided in each groove 2, and a corresponding stop block B7 is provided on each connecting rod 42. When the nut sleeve 5 rotates on the connecting rod 42, the movement of the nut sleeve 5 drives the connecting rod 42 to move within the positioning rod 41, thereby causing the stop block B7 to gradually move closer to the stop block A6. When the stop block B7 and the stop block A6 approach and contact each other, the position of the positioning component 4 on the positioning ring 1 is fixed, and it can no longer slide along the groove 2, thus completing the precise installation and fixation of the positioning component 4 on the positioning ring 1.

[0027] Structure and application of locking block 3 and locking lever 31

[0028] One or more locking blocks 3 are mounted on the positioning ring 1, each locking block 3 being designed with an internal groove structure. Each locking block 3 is equipped with a slidably connected locking rod 31, on which a spring element A32 is fitted. The two ends of the spring element A32 are tightly connected to the locking block 3 and the locking rod 31, respectively. For example, the spring element A32 can be a tension spring, with one end fixed at a specific position inside the locking block 3 and the other end fixed to the locking rod 31. When it is necessary to fix the positioning ring 1 to a flange not installed on a pipe, the operator pulls the locking rod 31, causing it to retract into the locking block 3. During this process, the spring element A32 is stretched, storing elastic potential energy. When the groove of the locking block 3 aligns with the flange and engages with it, the operator releases the locking rod 31. At this point, under the action of the elastic potential energy stored in the spring element A32, the locking rod 31 quickly rebounds and presses against the flange, thereby achieving stable fixation between the positioning ring 1 and the flange. In practice, in many cases, simply snapping the clip 3 onto the flange using its groove is sufficient to meet the initial positioning requirements.

[0029] For the installation and use of the positioning ring 1, when the flange to be replaced or installed is already installed on the pipeline, firstly, separate half-ring A101 and half-ring B102 using the snap-fit ​​mechanism on the positioning ring 1. Then, place half-ring A101 and half-ring B102 around the pipeline respectively, so that the positioning ring 1 can be fitted onto the pipeline. Next, reconnect half-ring A101 and half-ring B102 using the snap-fit ​​mechanism, thus completing the installation of the positioning ring 1 on the pipeline. After installation, insert the positioning element 4, which is located in the sliding groove 2 of the positioning ring 1, into the bolt hole of the flange to be replaced, ensuring that the positioning rod 41 can pass through the bolt hole of the flange. Subsequently, the operator picks up the new flange, aligns the bolt hole on the new flange with the positioning rod 41, and inserts it. At this time, the positioning rod 41 plays a role in positioning and initially fixing the new flange. When fixing the new flange, the operator inserts the bolts connecting the two flanges into the bolt holes, with one end of the bolt abutting against the positioning rod 41. Next, the operator uses a tool (such as a wrench) to turn the bolt. As the bolt rotates, it gradually penetrates deeper into the bolt hole. Simultaneously, the bolt exerts a compressive force on the positioning rod 41, causing it to overcome the resistance of the elastic element B43 and retract towards the connecting rod 42. When the bolt continues to penetrate until the positioning rod 41 is completely extruded from the bolt hole, the operator can remove the positioning ring 1 from the pipe or flange, thus completing the auxiliary installation process for the flange. Throughout the process, no multiple people are required to support the flange. This significantly reduces the difficulty of manual operation and improves installation efficiency, especially for large flanges used in large pipelines.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
