Description

Technical Field

[0001] This utility model belongs to the field of pipeline connection technology, and in particular relates to a simple and efficient flange assembly device. Background Technology

[0002] As a key component in pipeline connections, the quality of flange assembly directly affects the sealing performance, safety, and service life of the entire pipeline system. Flange assembly refers to the precise connection between the flange and the pipeline, ensuring that their axes coincide and their end faces are parallel, laying the foundation for subsequent welding or bolting connections. It is a frequent and critical procedure in pipeline construction.

[0003] Flanges typically require manual support during assembly. However, uneven force applied by workers and body swaying during this process can easily cause the flanges to shift, making it difficult to ensure the concentricity and parallelism of the flanges and pipes. This results in low efficiency and impacts the project schedule. Furthermore, for heavy flanges, if they slip during manual support, it could cause equipment damage or personal injury, reducing the safety of the flange assembly process.

[0004] Therefore, we propose a simple and efficient flange assembly tool to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of manual support required during flange assembly in the prior art, and to propose a simple and efficient flange assembly device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A simple and efficient flange assembly includes a first connecting rod, a second connecting rod below the first connecting rod, two connecting handles fixedly connected to the outer surfaces of the first and second connecting rods, a threaded rod rotatably connected to the interior of the first and second connecting rods, a push rod threadedly connected to the outer surface of the threaded rod, the push rod slidably connected to the interior of the first connecting rod, an auxiliary block fixedly connected to the top of the push rod, a crossbar provided inside the auxiliary block, two limiting holes opened inside the crossbar, two sets of limiting rods slidably connected inside the auxiliary block, the ends of each set of limiting rods extending into the limiting holes, an auxiliary ring fixedly connected to the outer surface of each set of limiting rods, a return spring sleeved on the outer surface of each set of limiting rods, the ends of each set of return springs fixedly connected to the ends of the auxiliary rings, and the ends of each set of return springs fixedly connected to the inner wall of the auxiliary block.

[0007] Preferably, an auxiliary bearing is fitted onto the outer surface of the threaded rod, and the auxiliary bearing is embedded inside the second connecting rod.

[0008] Preferably, a connecting ring is fixedly connected to the outer surface of the threaded rod, and a plurality of equally spaced push blocks are fixedly connected to the outer surface of the connecting ring.

[0009] Preferably, two guide blocks are fixedly connected to the outer surface of the top rod, and each guide block is slidably connected to the inside of the first connecting rod.

[0010] Preferably, a first rubber pad is fixedly connected to the outer surface of the second connecting rod, and a second rubber pad is fixedly connected to the upper surface of the crossbar.

[0011] Preferably, a retaining ring is fixedly connected to the outer surface of the top rod, and the top end of the retaining ring is fixedly connected to the bottom surface of the auxiliary block.

[0012] Preferably, both sets of limiting rods have a stop block fixedly connected to their ends that are far apart from each other, and an auxiliary handle is fixedly connected to the sides of the two stop blocks that are far apart from each other.

[0013] Preferably, a reinforcing ring is fixedly connected to the outer surface of each of the auxiliary handles, and the ends of the two sets of reinforcing rings that are close to each other are fixedly connected to the side of the stop block that is far from each other.

[0014] In summary, the technical effects and advantages of this utility model are as follows: The system comprises a first connecting rod, a second connecting rod, a connecting handle, a threaded rod, a top rod, an auxiliary block, a crossbar, a limiting hole, a limiting rod, an auxiliary ring, and a return spring. The second connecting rod is inserted into the edge of the pipe opening. Rotating the threaded rod causes the top rod, auxiliary block, and crossbar to rise, locking the inner wall of the pipe. The long side of the crossbar extends out of the pipe opening to hold the flange. Since the two edge lines of the crossbar are parallel to the pipe's natural line after it is fixed, the inner surface of the flange is naturally flush with the inner surface of the pipe after the flange is hung. The limiting rod can also be pulled out of the limiting hole, compressing the return spring. At this point, the crossbar is not subject to external forces. The system eliminates interference from external objects, allowing for easy removal of the crossbar from the auxiliary block. This facilitates subsequent disassembly, placement, or replacement of the crossbar. The continuous elastic force of the return spring ensures the stability of the limit rod during its positioning process. This eliminates the need for manual support, which is crucial because uneven force applied by workers and body swaying during manual support can easily cause flange misalignment, making it difficult to ensure the concentricity and parallelism of the flange and pipeline, resulting in low efficiency and impacting the construction period. For heavy flanges, slippage during manual support could cause equipment damage or personnel injury. This system improves the safety of flange assembly. Attached Figure Description

[0017] 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.

[0018] Reference Figure 1-4 A simple and efficient flange assembly includes a first connecting rod 1, a second connecting rod 2 located below the first connecting rod 1, two connecting handles 3 fixedly connected to the outer surfaces of the first connecting rod 1 and the second connecting rod 2, and a threaded rod 4 rotatably connected inside the first connecting rod 1 and the second connecting rod 2. An auxiliary bearing 12 is sleeved on the outer surface of the threaded rod 4 and embedded inside the second connecting rod 2. The auxiliary bearing 12 can reduce the friction generated by the threaded rod 4 during rotation, making the threaded rod 4 more sensitive during rotation, and also reducing the wear rate of the threaded rod 4 and increasing the durability of the threaded rod 4.

[0019] The outer surface of the threaded rod 4 is threadedly connected to a push rod 5, which is slidably connected to the inside of the first connecting rod 1. The outer surface of the threaded rod 4 is fixedly connected to a connecting ring 13, and the outer surface of the connecting ring 13 is fixedly connected to a plurality of equally spaced push blocks 14. By utilizing the cooperation between the connecting ring 13 and the push blocks 14, a good force-bearing point can be provided for the threaded rod 4, increasing the ease of rotation of the threaded rod 4 and improving the convenience of the device in use.

[0020] An auxiliary block 6 is fixedly connected to the top of the top rod 5. A crossbar 7 is provided inside the auxiliary block 6. Two limiting holes 8 are opened inside the crossbar 7. Two guide blocks 15 are fixedly connected to the outer surface of the top rod 5. Each guide block 15 is slidably connected to the inside of the first connecting rod 1. The guide block 15 can move simultaneously with the top rod 5 and use the friction force generated by itself on the first connecting rod 1 during the movement to improve the stability during the movement and limit the movement distance of the top rod 5.

[0021] The auxiliary block 6 has two sets of limiting rods 9 slidably connected inside. The ends of each set of limiting rods 9 that are close to each other extend into the interior of the limiting hole 8. The outer surface of the second connecting rod 2 is fixedly connected to the first rubber pad 16, and the upper surface of the crossbar 7 is fixedly connected to the second rubber pad 17. The first rubber pad 16 can increase the anti-slip effect of the second connecting rod 2 when supporting the pipe wall and increase the stability when supporting. The second rubber pad 17 can increase the anti-slip effect of the crossbar 7 when contacting the pipe wall and increase the effectiveness of the device.

[0022] Each set of limiting rods 9 has an auxiliary ring 10 fixedly connected to its outer surface, and a return spring 11 is sleeved on the outer surface of each set of limiting rods 9. The top surface of the top rod 5 has a retaining ring 18 fixedly connected to its outer surface. The top of the retaining ring 18 is fixedly connected to the bottom surface of the auxiliary block 6. The retaining ring 18 can increase the fixed connection area between the top rod 5 and the auxiliary block 6, thereby making the connection between the two more secure and preventing the possibility of breakage at the connection after long-term use, thus increasing the robustness of the device.

[0023] The ends of each set of return springs 11 that are close to each other are fixedly connected to the ends of the auxiliary rings 10 that are far apart from each other. The ends of the two sets of limit rods 9 that are far apart from each other are fixedly connected to a stop block 19. The sides of the two stop blocks 19 that are far apart from each other are fixedly connected to an auxiliary handle 20. By using the cooperation of the stop block 19 and the auxiliary handle 20, a good force point can be provided for the limit rod 9, increasing the ease of rotation of the limit rod 9 and improving the convenience of the device in use.

[0024] Each set of return springs 11 has its opposite ends fixedly connected to the inner wall of the auxiliary block 6. Each auxiliary handle 20 has a reinforcing ring 21 fixedly connected to its outer surface. The opposite ends of the two sets of reinforcing rings 21 are fixedly connected to the opposite sides of the stop block 19. The reinforcing rings 21 can increase the fixed connection area between the auxiliary handle 20 and the stop block 19, thereby making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the robustness of the device.

[0025] The working principle of this utility model is as follows: In use, the second connecting rod 2 is inserted into the edge of the pipe opening through the connecting handle 3. Then, the threaded rod 4 is rotated by the cooperation of the connecting ring 13 and the push block 14. The auxiliary bearing 12 can increase the sensitivity of the threaded rod 4 during rotation, thereby causing the top rod 5 to move within the first connecting rod 1. The guide block 15 can limit the movement distance of the top rod 5. The top rod 5 drives the auxiliary block 6 and the crossbar 7 to rise, and the second rubber pad 17 on the upper surface of the crossbar 7 is pressed against the inner wall of the pipe, thereby fixing the crossbar 7. At this time, the flange can be hung on the crossbar 7. Since the edge lines on both sides of the crossbar 7 are parallel to the pipe line after the crossbar 7 is fixed, the inner surface of the flange is naturally flush with the inner surface of the pipe. The assembly operation can be completed simply by adjusting the assembly gap. When it is necessary to disassemble, store, or replace the crossbar 7, the stop block 19 is moved by pulling the auxiliary handle 20, which in turn moves the limit rod 9 and the auxiliary ring 10, and moves the limit rod 9 out of the limit hole 8. At this time, the crossbar 7 is not restricted by external objects, and it can be removed from the auxiliary block 6, which facilitates the subsequent storage of the crossbar 7. When it is necessary to replace it, the crossbar 7 is placed into the auxiliary block 6, and then the auxiliary handle 20 is released. The rebound force generated by the return spring 11 drives the auxiliary ring 10 and the limit rod 9 to reset, and the limit rod 9 is inserted back into the limit hole 8, thereby completing the replacement of the crossbar 7, which effectively increases the convenience of the flange assembly process.
