Description

Technical Field

[0001] The utility model relates to the technical field of metal bellows splicing, in particular to a metal bellows splicing positioning 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] Since the existing large-scale metal bellows have a large diameter, in order to facilitate the transportation of large-scale metal bellows, the large-scale metal bellows are generally divided into two halves, and the two semicircular metal bellows are spliced ​​when they are transported to the construction site. In the process of splicing the two semicircular metal bellows, the two semicircular metal bellows need to be spliced ​​and positioned to facilitate splicing into a complete metal bellows. Therefore, we propose a metal bellows splicing and positioning device to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a metal bellows splicing and positioning device for solving the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A metal bellows splicing and positioning device comprises two supporting legs and two semicircular metal bellows, wherein the same pipe sleeve frame is fixedly mounted on the two supporting legs, and the two semicircular metal bellows are spliced ​​and placed in the pipe sleeve frame, and a connecting rod frame is fixedly mounted on one side of the pipe sleeve frame, and a mounting seat is fixedly mounted on the connecting rod frame, and a rotating groove is provided on the inner wall of the mounting seat, and a swivel is rotatably mounted in the rotating groove, and a bidirectional threaded column is fixedly mounted on the swivel, and two thread grooves are respectively arranged at both ends of the bidirectional threaded column, and threaded barrels are threadedly mounted on the thread grooves at both ends of the bidirectional threaded column, and corrugated clamps are fixedly mounted on one end of the two threaded barrels, and the two corrugated clamps are respectively clamped on the inner walls of the corresponding semicircular metal bellows, and a limiting mechanism is arranged between the two corrugated clamps.

[0007] Preferably, the cross-section of the rotating groove is arranged in a convex structure, and the rotating ring is adapted to the rotating groove, so that the rotating ring on the bidirectional threaded column can be easily rotated in the rotating groove in the mounting seat.

[0008] Preferably, the bidirectional threaded column is rotatably connected to the mounting seat, and the thread rotation directions of the two thread grooves on the bidirectional threaded column are opposite. Since the thread rotation directions of the two thread grooves on the bidirectional threaded column are opposite, when the bidirectional threaded column rotates, the two threaded barrels on the bidirectional threaded column are synchronously driven away from each other.

[0009] Preferably, the corrugated splint is arranged in an arc-shaped structure, and the outer wall of the corrugated splint is provided with a corrugated groove adapted to the corrugation of the semicircular metal bellows. The corrugated groove of the outer wall of the corrugated splint is clamped and fit on the corrugated inner wall of the semicircular metal bellows, so as to facilitate the corrugated groove of the corrugated splint to fit on the corrugated inner wall of the semicircular metal bellows.

[0010] Preferably, a turntable is fixedly mounted on the bidirectional threaded column, and the turntable is located above the mounting seat, so that the bidirectional threaded column can be rotationally adjusted by rotating the turntable.

[0011] Preferably, the limiting mechanism includes a limiting cylinder and a limiting rod, the inner wall of the upper corrugated clamping plate is respectively fixedly mounted with one end of two limiting cylinders, the other ends of the two limiting cylinders are both movable and extend to the outside of the mounting seat, the inner wall of the lower corrugated clamping plate is respectively fixedly mounted with one end of two limiting rods, the other ends of the two limiting rods are respectively movable and extend to the corresponding limiting cylinders, the limiting mechanism is used to achieve the two corrugated clamping plates being limited to prevent the two corrugated clamping plates from being offset during movement.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The metal bellows splicing and positioning device rotates a turntable on a bidirectional threaded column. Since the threads of two thread grooves on the bidirectional threaded column have opposite rotation directions, the two threaded barrels are synchronously driven to move away from each other, so that the two corrugated clamps on the two threaded barrels clamp and fix the two semicircular metal bellows on the inner wall of the pipe sleeve frame, thereby completing the splicing and positioning of the two semicircular metal bellows, so that the two semicircular metal bellows are spliced ​​into a complete metal bellows, and the operation is simple.

[0022] Furthermore, the cross section of the rotating groove 6 is arranged in a convex structure, and the rotating ring 7 is adapted to the rotating groove 6 , so that the rotating ring 7 on the bidirectional threaded column 8 can rotate in the rotating groove 6 in the mounting seat 5 .

[0023] Furthermore, the bidirectional threaded column 8 is rotatably connected to the mounting base 5, and the thread rotation directions of the two thread grooves 9 on the bidirectional threaded column 8 are opposite. Since the thread rotation directions of the two thread grooves 9 on the bidirectional threaded column 8 are opposite, when the bidirectional threaded column 8 rotates, the two threaded tubes 10 on the bidirectional threaded column 8 are synchronously driven away from each other.

[0024] Furthermore, the corrugated splint 11 is arranged in an arc-shaped structure, and the outer wall of the corrugated splint 11 is provided with a corrugated groove adapted to the corrugation of the semicircular metal bellows 2. The corrugated groove of the outer wall of the corrugated splint 11 is clamped and fitted on the corrugated inner wall of the semicircular metal bellows 2, so as to facilitate the corrugated groove of the corrugated splint 11 to fit on the corrugated inner wall of the semicircular metal bellows 2.

[0025] Specifically, a turntable 14 is fixedly mounted on the bidirectional threaded column 8 , and the turntable 14 is located above the mounting seat 5 , so that the bidirectional threaded column 8 can be rotated and adjusted by rotating the turntable 14 .

[0026] Specifically, the limiting mechanism includes a limiting cylinder 12 and a limiting rod 13. The inner wall of the upper corrugated clamp 11 is fixedly installed with one end of two limiting cylinders 12, and the other ends of the two limiting cylinders 12 are movable to penetrate outside the mounting seat 5.

Since the two thread grooves 9 on the two-way threaded column 8 have opposite thread rotation directions, the two threaded cylinders 10 are synchronously driven away from each other. At the same time, the two limiting rods 13 on the lower corrugated clamping plate 11 slide in the two limiting cylinders 12 on the upper corrugated clamping plate 11 respectively, so as to limit the two corrugated clamping plates 11 and prevent the two corrugated clamping plates 11 from deviating during the movement. The two corrugated clamps 11 clamp and fix the two semicircular metal bellows 2 on the inner wall of the pipe sleeve frame 3, thereby completing the splicing and positioning of the two semicircular metal bellows 2, which is convenient for the subsequent fastening and installation of the splicing of the two semicircular metal bellows 2; the method in this case, by screwing the turntable 14 on the two-way threaded column 8, since the thread rotation directions of the two thread grooves 9 on the two-way threaded column 8 are opposite, the two threaded cylinders 10 are synchronously driven away from each other, so that the two corrugated clamps 11 on the two threaded cylinders 10 clamp and fix the two semicircular metal bellows 2 on the inner wall of the pipe sleeve frame 3, thereby completing the splicing and positioning of the two semicircular metal bellows 2, so that the two semicircular metal bellows 2 are spliced ​​into a complete metal bellows, which is easy to operate.
