Description

Technical Field

[0001] The present invention relates to the technical field of pipeline installation, and particularly relates to a pipeline installation positioning device. Background Art

[0002] In order to save space, facilitate maintenance, and have good ventilation, the connecting pipelines between various equipment in a chemical production plant are installed overhead. Among them, the pipelines are connected to the equipment by flanges. To ensure the sealing performance of the pipelines, the connections between pipelines are mostly welded. During installation, some pipelines are first welded together, and then the overhead pipelines are butted according to the requirements of the pipeline layout.

[0003] When welding pipelines, the pipelines need to be supported and positioned. In addition, if the concentricity of the two pipelines cannot be ensured during the welding process, the welding quality cannot meet the requirements. For the welding between pipelines, when the butting surface of the pipelines is inclined, the butting angle needs to be accurately ensured on the premise of ensuring concentricity. For this reason, we have proposed a pipeline installation positioning device. Summary of the Invention

The clamping mechanism 3 drives the pipeline 42 to move to adjust the distance between the pipeline 42 and the pipeline 41. The rotating unit 22 drives the clamping unit 23 to rotate and drives the pipeline 41 to rotate to adjust the docking surface angle between the pipeline 41 and the pipeline 42.

[0028] Specifically, a fixed platform 11 is arranged at the top of the bottom plate 1, the fixing shell 21 is vertically arranged on the fixed platform 11. The rotating unit 22 includes a rotating ring 221 rotatably arranged on the fixing shell 21, a first gear ring 222 arranged on one side of the rotating ring 221, a first gear 223 rotatably arranged on the fixing shell 21, and a first motor 224 arranged on one side of the fixing shell 21. The first gear ring 222 and the first gear 223 are both arranged inside the fixed ring, the first gear ring 222 and the first gear 223 are meshed with each other, and the first gear 223 is arranged at the output end of the first motor 224. The first motor 224 drives the first gear 223 to rotate, the first gear 223 drives the first gear ring 222 to rotate, and at the same time drives the rotating ring 221 to rotate. The rotation of the rotating ring 221 drives the whole clamping unit 23 to rotate, thereby controlling the pipeline 41 to rotate and adjusting the docking surface angle between the pipeline 41 and the pipeline 42.

[0029] The clamping unit 23 includes a second gear ring 231 rotatably arranged on the side of the rotating ring 221 away from the first gear ring 222, a first moving block 232 movably arranged on one side of the rotating ring 221, a second moving block 233 slidably arranged on one side of the rotating ring 221, a first movable block 234 slidably connected to the first moving block 232, and a second movable block 235 slidably connected to the second moving block 233.

[0030] A first fixing block 2211 is arranged on one side of the rotating ring 221. A threaded rod 236 is rotatably arranged in the first moving block 232, and the threaded rod 236 is rotatably connected to the first fixing block 2211. Rotating the threaded rod 236 can control the first moving block 232 to move back and forth on the threaded rod 236.

[0031] Such as Figure 1 , a housing 2212 is arranged on one side of the rotating ring 221. The threaded rod 236 penetrates through the housing 2212, and the threaded rod 236 is rotatably connected to the housing 2212. A rotating block is arranged at one end of the threaded rod 236.

[0033] A first convex strip 2321 is arranged on the side of the first moving block 232 away from the rotating ring 221. The first convex strip 2321 is inclined. There are multiple first convex strips 2321, and the multiple first convex strips 2321 are arranged in parallel. A first groove is arranged at the bottom end of the first movable block 234. The first convex strip 2321 matches the first groove. The first moving block 232 is perpendicular to the first movable block 234, and the first movable block 234 faces the center of the rotating ring 221. When the first moving block 232 moves on the threaded rod 236, it can drive the first movable block 234 to move in the radial direction of the rotating ring 221, so as to move away from or close to the center of the rotating ring 221.

[0036] On one side of the second moving block 233 away from the rotating ring 221, a second convex strip 2331 is provided. The second convex strip 2331 is inclined. There are multiple second convex strips 2331, and the multiple second convex strips 2331 are arranged in parallel. A second groove is provided at the bottom end of the second movable block 235. The second convex strip 2331 matches the second groove. The second moving block 233 is perpendicularly arranged with the second movable block 235. The second movable rod block 235 is arranged towards the center of the rotating ring 221. When the second moving block 233 moves, it can drive the second movable block 235 to move in the radial direction of the rotating ring 221, so as to move away from or close to the center of the rotating ring 221.

[0037] A first clamping block 2341 is detachably arranged on one side of the first movable block 234, and a second clamping block 2351 is detachably arranged on one side of the second movable block 235.

[0038] Such as Figures 4-6 , when rotating the threaded rod 236 to drive the first moving block 232 to move to the right, the first moving block 232 drives the first movable block 234 to approach the center of the second gear ring 231. At the same time, the first moving block 232 drives the second gear ring 231 to rotate clockwise. The clockwise rotation of the second gear ring 231 drives the second moving block 233 to move to one side. The second moving block 233 drives the second movable block 235 to approach the center of the second gear ring 231. The first clamping block 2341 and the second clamping block 2351 clamp the second pipeline 42. Similarly, when rotating the threaded rod 236 in the reverse direction to drive the first moving block 232 to move to the left, the first clamping block 2341 and the second clamping block 2351 loosen the second pipeline 42.

The pair of clamping members 33 are rotatably arranged at both ends of the bidirectional lead screw 35. The second motor 34 drives the bidirectional lead screw 35 to rotate. The rotation of the bidirectional lead screw 35 drives the pair of clamping members 33 to approach or move away from each other, so as to clamp or loosen the second pipeline 42.
