Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline flange connection technical field especially relates to pipeline flange installation positioning device. BACKGROUND

[0002] When connecting the pipeline with flange, the flange plates between two pipelines are not aligned, which is a common engineering problem due to the influence of machining error, installation error, welding deformation and temperature factors. If the two flange plates are not aligned, the bolt connection holes between the two flange plates cannot be aligned, and the construction personnel cannot directly connect the two pipelines through the bolt. The construction personnel need to manually adjust the position of the pipeline, and after aligning the two flange plates, the two flange plates can be bolted. However, manually correcting the position of the flange plate is time-consuming and labor-intensive, which affects the connection efficiency of the pipeline and seriously delays the installation progress of the pipeline.

[0028] Figure 1 A front structural schematic view of a pipe flange installation positioning device is shown. Figure 2A right view structural schematic diagram of the pipeline flange installation positioning device of the embodiment of the present disclosure is shown after the pipeline flange installation positioning device is installed on a pipe body. Please refer to Figure 1 and Figure 2 The pipeline flange installation positioning device comprises a circular arc top plate 1 which contacts the outer surface of the pipe body 5. The circular arc top plate 1 is provided with a base 11 and a positioning column 4 away from the surface of the pipe body 5. The clamping mechanism 2 comprises a left arc-shaped plate 22 and a driving assembly 21. The left arc-shaped plate 22 is connected to the base 11 through the driving assembly 21. The circular arc top plate 1 and the left arc-shaped plate 22 which enclose a ring-shaped assembly are pushed to clamp the pipe body 5 through the driving assembly 21. The positioning column 4 is arranged along the length direction of the pipe body 5. Along the radial direction of the pipe body 5, a threaded top rod 41 is arranged at the end of the positioning column 4 away from the circular arc top plate 1. The driving assembly 21 drives the left arc-shaped plate 22 to contact the outer surface of the pipe body 5. The circular arc top plate 1 and the left arc-shaped plate 22 enclose a ring-shaped assembly. While the pipeline flange installation positioning device clamps the pipe body 5, the threaded top rod 41 on the positioning column 4 can point to the flange plate 6 of another pipe body 5. The threaded top rod 41 can be extended from the positioning column 4 and push the flange plate 6 of another pipe body 5 by driving the threaded top rod 41 to rotate, so as to correct the position error between the flange plates 6 of the two pipe bodies 5, quickly align the two flange plates 6, and bolt the two flange plates 6. By using the pipeline flange installation positioning device, the two flange plates 6 can be quickly pushed to align, which is convenient for the construction personnel to bolt the two flange plates 6 and improves the installation efficiency of the pipeline.

[0029] Please refer to Figure 1 and Figure 2 The driving assembly 21 comprises a first screw rod 211 and a driving nut 212. The first screw rod 211 passes through the base 11, and the end of the first screw rod 211 away from the base 11 is rotationally connected to the left arc-shaped plate 22. The driving nut 212 is arranged on the first screw rod 211 between the left arc-shaped plate 22 and the base 11. The driving nut 212 drives the first screw rod 211 to extend or retract by rotating around the first screw rod 211, and the length of the first screw rod 211 between the driving nut 212 and the driven seat 221 is adjusted to support the left arc-shaped plate 22 to contact the pipe body 5, so that the circular arc top plate 1 and the left arc-shaped plate 22 clamp the pipe body 5 and fix the position of the pipeline flange installation positioning device.

[0030] Preferably, a strip-shaped slot 213 is formed on the base 11 along the radial direction of the pipe body 5. The driving assembly 21 further comprises a limiting rod 214. One end of the limiting rod 214 is slidably connected to the base 11 through the strip-shaped slot 213, and the other end of the limiting rod 214 is rotationally connected to the left arc-shaped plate 22. The strip-shaped slot 213 cooperates with the limiting rod 214 to limit the movement track of the left arc-shaped plate 22, so as to ensure that the left arc-shaped plate 22 correctly clamps or releases the pipe body 5. At the same time, the movement stroke of the left arc-shaped plate 22 is limited, so as to avoid the first screw rod 211 from sliding out of the base 11 when the left arc-shaped plate 22 is not stressed.

[0031] More preferably, the base 11 is rotatably provided with a connecting block 12. The first screw rod 211 passes through the connecting block 12. The first screw rod 211 is rotatably connected to the base 11 through the connecting block 12. In some embodiments, the base 11 can be a hollow structure, and the connecting block 12 is arranged inside the base 11 to better support the first screw rod 211.

[0032] Please refer to Figure 1 and Figure 2 The driven seat 221 is arranged on the left arc-shaped plate 22. The first screw rod 211 is rotatably connected to the driven seat 221, and the limiting rod 214 is also rotatably connected to the driven seat 221 to rotatably connect the left arc-shaped plate 22. A gap is left between the circular arc top plate 1 and the left arc-shaped plate 22. The left arc-shaped plate 22 is prevented from interfering with the circular arc top plate 1.

[0033] Preferably, the driving assembly 21 and the base 11 are symmetrically arranged in two groups around the axis of the pipe body 5. One group of the driving assembly 21 and the base 11 is connected to the left arc-shaped plate 22, and the other group of the driving assembly 21 and the base 11 is connected to the right arc-shaped plate 3. The circular arc top plate 1, the left arc-shaped plate 22 and the right arc-shaped plate 3 form an annular assembly. Through the left arc-shaped plate 22 and the right arc-shaped plate 3, the pipe body 5 is simultaneously held on both sides, thereby improving the connection strength between the pipe flange mounting positioning device and the pipe body 5.

[0034] More preferably, gaps are respectively left between adjacent circular arc top plates 1, left arc-shaped plates 22 and right arc-shaped plates 3. When the driving assembly 21 drives the left arc-shaped plate 22 and the right arc-shaped plate 3 to swing, interference between the arc top plates, the left arc-shaped plates 22 and the right arc-shaped plates 3 is avoided.

[0035] Please refer to Figure 1 and Figure 2 The wing-shaped plate 42 is arranged on the threaded top rod 41 away from the pipe body 5 on the side of the positioning column 4. The wing-shaped plate 42 is fixedly connected to the threaded top rod 41. The threaded top rod 41 is threadedly connected to the positioning column 4. The wing-shaped plate 42 is arranged to facilitate adjustment of the relative position between the threaded top rod 41 and the positioning column 4. By rotating the threaded top rod 41 through the wing-shaped plate 42, the relative position between the threaded top rod 41 and the positioning column 4 can be adjusted, and the threaded top rod 41 is driven to abut against or away from the flange plate 6.

[0036] The specific working process of the utility model is as follows:

[0037] When aligning the flanges 6 between two pipes, first, the circular arc top plate 1, the left arc plate 22 and the right arc plate 3 are sleeved on the pipe body 5. The position of the circular arc top plate 1 is adjusted until the threaded top rod 41 is aligned with the flange 6 of the other pipe body 5. Then the driving nut 212 is rotated to drive the first screw rod 211 to extend out through the thread. At this time, the length of the first screw rod 211 between the base 11 and the left arc plate 22 and between the base 11 and the right arc plate 3 is increased, and the first screw rod 211 pushes the left arc plate 22 and the right arc plate 3 to fit the pipe body 5, and the pipe flange installation positioning device is fixed on the pipe body 5. Then the threaded top rod 41 is driven to rotate through the wing-shaped plate 42, and the threaded top rod 41 is driven to approach the flange 6 until the threaded top rod 41 pushes the flange 6 to move, and the flanges 6 between the two pipes are aligned. The positioning between the two pipe bodies 5 is completed.
