[0023] like Figures 1 to 5 As shown, an extrusion slope 9 is formed on the inner ring wall of the collar 3 away from the positioning rod 4 .

[0024] After the sleeve ring 3 is put on the outside of the pipe 1, the extrusion slope 9 on the sleeve ring 3 will squeeze one end of the flange 2 on the pipe 1 to control the fixation between the flanges 2 on the two pipes 1 to prevent the two pipes 1 from swinging.

[0025] like Figures 1 to 5 As shown, one end of the collar 3 with the block 7 is fixedly installed with a fixing plate 10, and a first sliding hole 11 is symmetrically opened in the middle of the fixing plate 10, and a sliding rod 12 is slidably installed inside the first sliding hole 11, and the end of the sliding rod 12 is fixedly connected to the block 7, and a first extrusion spring 13 is sleeved on the outer side of the end of the sliding rod 12 away from the block 7, one end of the first extrusion spring 13 is fixedly connected to the fixing plate 10, and the other end of the first extrusion spring 13 is fixedly connected to the end of the sliding rod 12 away from the block 7, and a first mounting plate 14 is fixedly installed between the ends of the two sliding rods 12 away from the block 7.

[0026] When the collar 3 is closed, the block 7 will be squeezed by the fixed block 5 first, and at this time the first squeezing spring 13 is in an elongated state. After the collar 3 is closed, the first squeezing spring 13 will pull the slide bar 12 to slide inside the first slide hole 11, and the block 7 will slide into the slot 6 to fix the two collars 3.

[0027] like Figures 1 to 5 As shown, an extrusion rod 15 is threadedly installed in the middle of the fixing plate 10, and the extrusion rod 15 is aligned with the block 7. The end of the extrusion rod 15 passes through the first mounting plate 14 and is slidably connected to the first mounting plate 14. A knob 16 is fixedly installed on the end of the extrusion rod 15.

[0028] When the installation of the collar 3 is unstable, the knob 16 can be turned to drive the extrusion rod 15 to rotate and move in the middle of the fixed plate 10, which can drive the extrusion rod 15 to squeeze the block 7 and stably fix the block 7 inside the slot 6 to prevent the two collars 3 from rotating relative to each other and stably install the collar 3 on the outside of the pipe 1 and the flange 2.

One end of the second extrusion spring 18 is fixedly connected to the ring 3, and the other end of the second extrusion spring 18 is fixedly connected to one side of the ring 3. A second mounting plate 19 is fixedly installed between the two second extrusion springs 18.

[0030] After driving the pipeline 1 to rotate, the mounting holes on the flanges 2 of the two pipelines 1 will correspond to each other. The second extrusion spring 18 will pull the positioning rod 4 to drive the positioning rod 4 to be inserted into the mounting holes on the flanges 2 of the two pipelines 1, so that the two pipelines 1 can be aligned. Then, the bolts are passed through the mounting holes on the flanges 2, and the positioning rod 4 is slid out of the mounting holes on the flanges 2 under the extrusion of the bolt column, so that the two pipelines 1 can be assembled.

[0031] like Figures 1 to 5 As shown, one end of the positioning rod 4 away from the second mounting plate 19 is provided with a chamfer 20 .

[0032] It is convenient to slide the positioning rod 4 into the mounting hole on the flange 2.

[0034] The meshing of the driving gear 22 and the gear ring 8 will drive the rotating ring 24 to rotate inside the rotating groove 23, thereby driving the gear ring 8 to rotate. Since the inner wall of the gear ring 8 and the outer wall of the pipe 1 are fixed by friction, it will be convenient to drive the pipe 1 to rotate.

[0035] The utility model provides a chemical equipment pipeline installation centering mechanism, the specific working principle is as follows:

[0036] When the device is in use, the pipeline 1 is lifted by a crane, etc., and then the pipeline 1 is moved to one end of the previous pipeline 1, and the collar 3 is rotated and sleeved on the outside of the flanges 2 on the two pipelines 1, and then the collar 3 is relatively rotated to put the collars 3 together to form a circle. At this time, one side of the collar 3 will squeeze the flange 2 at one end of the previous pipeline 1, and the extrusion slope 9 on the collar 3 will squeeze one end of the flange 2 on the pipeline 1, which is used to control the fixation between the flanges 2 on the two pipelines 1 to prevent the two pipelines 1 from swinging. In the above process, the ends of the positioning rod 4 are pulled by people. When the collar 3 is closed, the block 7 will be squeezed by the fixed block 5 first, and the first squeezing spring 13 is in an elongated state. After the collar 3 is closed, the slide bar 12 will be pulled by the first squeezing spring 13 to slide inside the first slide hole 11, and the block 7 will be slid into the card slot 6 to fix the two collars 3. In order to prevent the two collars 3 from rotating relative to each other, the squeezing rod 15 can be driven to rotate and move in the middle of the fixed plate 10 by turning the knob 16, which can drive the squeezing rod 15 to squeeze the block 7 and The block 7 is stably fixed inside the card slot 6 to prevent the two rings 3 from rotating relative to each other. At this time, the inner ring wall of the ring 3 close to the positioning rod 4 and the outer wall of the pipe 1 ensure the fixation between the ring 3 and the pipe 1 through friction. The inner wall of the gear ring 8 and the outer wall of the pipe 1 are also fixed through friction. Then the control of the positioning rod 4 is canceled. At this time, the second extrusion spring 18 is in an elongated state. Then the control motor 21 is operated to drive the driving gear 22 to rotate. The meshing of the driving gear 22 and the gear ring 8 will drive the rotating ring 24 to rotate inside the rotating groove 23, and then This drives the gear ring 8 to rotate. Since the inner wall of the gear ring 8 and the outer wall of the pipe 1 are fixed by friction, the pipe 1 will be driven to rotate. When the mounting holes on the flanges 2 of the two pipes 1 correspond to each other, the positioning rod 4 is pulled by the second extrusion spring 18 to drive the positioning rod 4 to be inserted into the mounting holes on the flanges 2 of the two pipes 1, so as to perform the centering operation on the two pipes 1. Then, the bolts are passed through the mounting holes on the flanges 2. Under the extrusion of the bolt column, the positioning rod 4 is slid out of the mounting holes on the flanges 2, so as to perform the assembly operation between the two pipes 1.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
