Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to the attached Figures 1 to 4 As shown, a flange butt joint position adjusting device in an embodiment of the present invention includes a housing 1. One side of the upper end of the housing 1 is fixedly connected with a side connector 5. The inner side of the side connector 5 is fixedly sleeved with a clamping post 6. The lower end of the housing 1 is fixedly connected with a lower connector 3. The inner side of the lower connector 3 is sleeved with a jack post 4.

[0029] One side of the housing 1 close to the clamping post 6 is connected with an adjusting ram 2. One side of the upper end of the housing 1 away from the clamping post 6 is provided with an adjusting assembly 9.

[0030] The adjusting ram 2 includes a pressure block 22. The rear end of the pressure block 22 extends into the housing 1 and is slidably sleeved with the housing 1. The rear end of the pressure block 22 is fixedly connected with a screw sleeve 24. The inner side of the screw sleeve 24 is sleeved with a screw rod 23. One end of the screw rod 23 is rotatably connected to the inner side of the housing 1, and the other end is fixedly connected with a first bevel gear 25. The ejection degree of the adjusting ram 2 can be adjusted. By rotating the screw rod 23, the extension degree of the pressure block 22 can be adjusted, which is convenient for pressing tightly against the flange.

[0031] The adjusting assembly 9 includes a rotating shaft 92 arranged inside the housing 1. The upper and lower ends of the rotating shaft 92 are rotatably connected to the inner wall of the housing 1. The outer end of the rotating shaft 92 is fixedly sleeved with a second bevel gear 93. The second bevel gear 93 is meshed with the first bevel gear 25. The adjusting assembly 9 is used to change the ejection degree of the adjusting ram 2. Specifically, by rotating the rotating shaft 92, through the transmission of the second bevel gear 93 and the first bevel gear 25, the screw rod 23 is driven to rotate, thereby adjusting the ejection degree of the pressure block 22.

[0032] The adjusting assembly 9 further includes a rotating handwheel 91. The rotating handwheel 91 is rotatably connected to the upper end of the housing 1, and the lower end of the rotating handwheel 91 is fixedly connected to the rotating shaft 92. By providing the adjusting handwheel 91, it is convenient to rotate the rotating shaft.

[0033] The top column 4 includes a stud 41. The stud 41 is threadedly sleeved with the lower connector 3. The inner end of the stud 41 is fixedly connected with a top plate 43, and the outer end of the stud 41 is fixedly connected with a hexagon head 42. When the top column 4 is in use, a long-handled wrench can be sleeved on the outer end of the hexagon head 42 for rotation. As the stud 41 rotates, the top plate 43 is tightened against the reference flange pipeline. As the top column 4 pushes, the clamping column 6 is driven to pull the flange to be adjusted for alignment.

[0034] The upper end of the clamping column 6 extends out of the side connector 5 and is fixedly connected with a connecting ring 7. The outer side of the connecting ring 7 is connected with a lock 8 through a strap. By providing the connecting ring 7 and the lock 8, it is convenient for the device to be carried and stored. In addition, when in use, the strap of the lock 8 can be wound around the outer end of the pipeline, and the lock 8 can be buckled on the hanging ring 7 to be used as a safety belt to prevent the clamping column 6 from accidentally coming out and causing danger.

[0035] The front end face of the housing 1 is fixedly connected with an outer baffle 10 through screws. The provided outer baffle 10 is connected through screws and can be disassembled, which is convenient for the maintenance of the inside of the housing 1.

[0036] The outer end of the pressing block 22 is fixedly connected with a pressing plate 21. The outer surface of the pressing plate 21 is set as a rough surface. The provided pressing plate 21 is used to abut against the flange, playing an auxiliary fixing role. The outer surface of the pressing plate 21 being a rough surface can enhance the friction force of the contact surface and play an anti-slip effect.

[0037] Both the housing 1 and the clamping column 6 are made of high-strength carbon steel. The housing 1 and the clamping column 6 made of high-strength carbon steel have high mechanical strength and strong reliability.

[0038] Working principle: When in use, first insert the provided clamping column 6 into the largest misalignment hole position on the flange to be adjusted. Then rotate the rotating handwheel 91 of the adjusting assembly 9. Through the transmission of the second bevel gear 93 and the first bevel gear 25, the screw 23 is driven to rotate, thereby adjusting the ejection degree of the pressing plate 21 so that the pressing plate 21 is closely attached to the reference flange, thus completing the fixation. Then use a long-handled wrench to sleeve on the outer end of the hexagon head 42 of the top column 4 for rotation. By the pushing of the top plate 43, the clamping column 6 is driven to pull the flange connected to it, so that the upper and lower flanges are aligned. By adjusting the ejection degree of the top column 4, the docking position of the flange is adjusted. The controllability is strong, and there is no knocking vibration during adjustment, and the flange will not be damaged during adjustment.

[0039] The above has described in detail an embodiment of the present utility model, but the above content is only a preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of application of the present utility model shall still fall within the scope covered by the patent of the present utility model.
