Description

Technical Field

[0001] The utility model relates to the technical field of metal bellows splicing, in particular to a metal bellows splicing construction auxiliary device. Background Art

[0002] Metal bellows is a flexible pipe component made of metal, usually made of stainless steel or other corrosion-resistant metals; its main structural feature is the wavy folds or corrugations on the pipe wall, which enable the pipe to have a certain degree of elasticity and flexibility when subjected to pressure or temperature changes.

[0003] The existing splicing of metal corrugated pipes is often to splice the metal corrugated pipes section by section into a longer metal corrugated pipe at the construction site, and then weld the joints of the two sections of the metal corrugated pipes. The traditional splicing method of two sections of metal corrugated pipes often requires manual splicing, which is inefficient. Therefore, we propose a metal corrugated pipe splicing construction auxiliary device to solve the above problems. Utility Model Content

[0025] Furthermore, the limiting mechanism includes a limiting baffle 6, a top plate 7 and a spring 8. The limiting baffle 6 is movably installed in the translation plate 5, and the top plate 7 is fixedly installed on one end of the limiting baffle 6 that penetrates the outside of the translation plate 5. The same spring 8 is fixedly installed between one side of the top plate 7 and one side of the translation plate 5; when one end of the metal bellows body 2 is squeezed to the right on the arc-shaped convex heads of the two limiting baffles 6, the two limiting baffles 6 are moved outward synchronously, so that the metal bellows body 2 moves to the two limiting baffles The right side position of the limiting baffle 6; the limiting baffle 6 is movably extended to one end inside the auxiliary tube frame 3 and is provided with an arc-shaped convex head, and the other side of the arc-shaped convex head on the limiting baffle 6 abuts against the port of the metal bellows body 2. When the two limiting baffles 6 extend to one end inside the auxiliary tube frame 3 to push the new metal bellows body 2 to move toward the port of the just-joined metal bellows body 2, the port of the new metal bellows body 2 is squeezed to the right and docked on the port of the just-joined metal bellows body 2.

[0026] Furthermore, the pushing mechanism includes a fixed block 9 and a hydraulic rod 10. Two fixed blocks 9 are fixedly installed on the auxiliary cylinder frame 3. A hydraulic rod 10 is fixedly installed on one side of the two fixed blocks 9. The output ends of the two hydraulic rods 10 are fixedly installed on one side of the corresponding translation plate 5. By starting the two hydraulic rods 10, the two translation plates 5, the fixed cylinder 11, the connecting plate 14 and the semicircular splicing frame 15 are pushed to the right, so that the semicircular splicing frame 15 continues to slide to the right on the newly spliced ​​metal bellows body 2, which plays a limiting role and facilitates the docking of the two sections of the metal bellows body 2.

[0027] Specifically, the connecting plate 14 is rotatably fitted on the auxiliary cylinder rack 3 , and one side of the semicircular splicing frame 15 is rotatably fitted on the port of the auxiliary cylinder rack 3 , so that the connecting plate 14 can be easily rotated on the auxiliary cylinder rack 3 .

[0028] Furthermore, the self-rotation drive mechanism includes a motor 17 and a gear 18. The motor 17 is fixedly mounted on the outer surface of the connecting plate 14, and the gear 18 is fixedly mounted on the output shaft of the motor 17. The gear 18 is meshed with the gear ring 16. By starting the motor 17, the gear 18 is meshed with the gear ring 16, thereby driving the connecting plate 14 and the rotating ring 13 to rotate, thereby realizing the rotation adjustment of the position of the semicircular splicing frame 15.

[0029] Specifically, a counterweight block 19 is provided in the auxiliary frame 1, and a plurality of universal wheels 20 are provided on the bottom side of the auxiliary frame 1. By providing the counterweight block 19 in the auxiliary frame 1, the tilting of the auxiliary frame 1 is reduced. By using the plurality of universal wheels 20 on the bottom side of the auxiliary frame 1, the auxiliary frame 1 can be easily moved to the port of the newly assembled metal bellows body 2.

[0030] During use: when splicing the metal bellows one by one at the construction site, the auxiliary frame 1 is moved to the port of the newly spliced ​​metal bellows body 2 through the multiple universal wheels 20 on the bottom side of the auxiliary frame 1. At this time, the semicircular splicing frame 15 is sleeved on one end of the newly spliced ​​metal bellows body 2. After that, the installer inserts the new metal bellows body 2 into the auxiliary tube frame 3. When one end of the metal bellows body 2 is squeezed to the right on the arc-shaped convex heads of the two limit baffles 6, the two limit baffles 6 move outward synchronously. At this time, the two springs 8 are deformed and stretched under the force until the new metal bellows body 2 moves to the right side position of the two limit baffles 6. After that, the two hydraulic rods 10 are started to push the two translation plates 5 to move to the right in the corresponding translation grooves 4, thereby moving the fixed tube 11, the connecting plate 14 and the semicircular splicing frame 15 to the right, so that the semicircular splicing frame 15 continues to slide to the right on the newly spliced ​​metal bellows body 2 , which is convenient for splicing the new metal bellows body 2 with the newly spliced ​​metal bellows body 2. At the same time, the two limit baffles 6 extend to one end of the auxiliary cylinder frame 3 to push the new metal bellows body 2 to move toward the port of the newly spliced ​​metal bellows body 2 until the port of the new metal bellows body 2 is squeezed to the right and docked on the port of the newly spliced ​​metal bellows body 2. At this time, there is a certain construction operation space between the right port of the auxiliary cylinder frame 3 and the side wall of the semicircular splicing frame 15. By starting the motor 17, the gear 18 is engaged with the gear ring 16, which drives the connecting plate 14 and the swivel 13 to rotate, thereby realizing the rotation adjustment of the position of the semicircular splicing frame 15, thereby facilitating the complete welding and other operations of splicing and fixing the two metal bellows bodies 2 at the port connection of the new metal bellows body 2 and the newly spliced ​​metal bellows body 2, thereby completing the splicing and installation of the two metal bellows bodies 2.

[0031] In summary, the method in this case is to insert the new metal bellows body 2 into the auxiliary cylinder frame 3, and push the two translation plates 5, the fixed cylinder 11, the connecting plate 14 and the semicircular splicing frame 15 to move to the right through the two hydraulic rods 10, so that the semicircular splicing frame 15 continues to slide to the right on the newly spliced ​​metal bellows body 2. At the same time, the two limit baffles 6 extend to one end of the auxiliary cylinder frame 3 to push the new metal bellows body 2 to move toward the port of the newly spliced ​​metal bellows body 2 until the port of the new metal bellows body 2 is squeezed to the right. It is pressed and docked on the port of the newly spliced ​​metal bellows body 2, and by starting the motor 17, the gear 18 is meshed with the gear ring 16, thereby driving the connecting plate 14 and the swivel 13 to rotate, thereby realizing the rotation adjustment of the position of the semicircular splicing frame 15, thereby facilitating the complete welding and other operations of splicing and fixing the two metal bellows bodies 2 at the port connection between the new metal bellows body 2 and the newly spliced ​​metal bellows body 2, thereby completing the splicing and installation of the two metal bellows bodies 2, and improving the splicing and installation efficiency of the metal bellows body 2.
