The first arcuate plate 22 contacts one of the flanges 101.
The arc-shaped groove 211 is internally provided with a sliding frame 26 capable of sliding left and right, specifically, the sliding frame 26 is of an arc-shaped plate structure, the sliding frame 26 is coaxial with the pipeline 100, the inner arc surface of the sliding frame 26 is attached to the outer wall of the pipeline 100, and the outer arc surface of the sliding frame 26 is attached to the wall surface of the arc-shaped groove 211. The carriage 26 is located the side that the second arc 23 deviates from the ring flange 101, and the second arc 23 passes through second elastic expansion link 27 with the carriage 26 and is connected, and second elastic expansion link 27 has a plurality ofly and evenly distributed along the circumference of second arc 23, and second elastic expansion link 27 is the same with first elastic expansion link 25 structure. When the second elastic telescopic rod 27 is in a natural state, a gap is reserved between the second arc-shaped plate 23 and the other flange plate 101.
The restricting frame 21 has a projection 212, a receiving groove 2121 communicating with the arc-shaped groove 211 is provided in the projection 212, the restricting frame 21 is connected with a first rack 213, the first rack 213 is located in the receiving groove 2121 and extends in the left-right direction, the carriage 26 is connected with a second rack 261, and the second rack 261 is located in the receiving groove 2121 and extends in the left-right direction. The first curved plate 22 has an ear plate, and the first gear 24 is located between the first rack 213 and the second rack 261 and is rotatably connected with the ear plate, and the first gear 24 is meshed with the first rack 213 and the second rack 261, respectively. The base 1 is provided with a pushing assembly 3 for pushing the restricting frame 21 to slide.
In this embodiment, it should be noted that the two locking devices 2 are distributed in a central symmetry manner with respect to the positions of the two flanges 101.
Initially, the two limiting frames 21 can be close to each other by pushing the assembly 3, the distance between the limiting frames 21 and the first arc-shaped plate 22 is reduced, the first elastic telescopic rod 25 is compressed and stores force, and the elastic force of the first elastic telescopic rod 25 acts on the flange 101 through the first arc-shaped plate 22, so that the first arc-shaped plate 22 compresses the flange 101.
Meanwhile, the limiting frame 21 drives the first rack 213 to move, the first rack 213 drives the first gear 24 to rotate, the first gear 24 drives the sliding frame 26 to move towards the flange 101 through the second rack 261, and the sliding frame 26 drives the second arc-shaped plate 23 to move through the second elastic telescopic rod 27. When the second arc-shaped plate 23 is pressed against the flange 101, the sliding frame 26 continues to move, the second elastic telescopic rod 27 is compressed and stores force, and the elastic force of the second elastic telescopic rod 27 acts on the flange 101 through the second arc-shaped plate 23, so that the second arc-shaped plate 23 compresses the flange 101. The first and second curved plates 22, 23 thus achieve a pre-compression of the two flanges 101, enhancing the stability of the connection of the two flanges 101. Therefore, the limiting frame 21, the first arc-shaped plate 22 and the second arc-shaped plate 23 are matched to only support and move the limiting flange 101 and the pipeline 100, and the pipeline 100 is not hooped, so that the structural damage of the pipeline 100 is reduced, and the service life of the pipeline 100 is prolonged.
When the two pipelines 100 and the flange plate 101 are disturbed by external force to shake left and right, the flange plate 101 pushes the first arc plate 22 to slide, at the moment, the limiting frame 21 cannot move along the first arc plate 22 in the same direction under the stop of the pushing component 3, and the first elastic telescopic rod 25 is continuously compressed, so that the pressing force of the first arc plate 22 on the flange plate 101 is increased.
Meanwhile, the first curved plate 22 drives the first gear 24 to slide, and the first gear 24 rotates due to the engagement of the first gear 24 and the first rack 213. The first gear 24 drives the second rack 261 to move, and it should be noted that, under the limitation of the meshing relationship, the moving speed of the second rack 261 will be greater than the moving speed of the first gear 24. Then, the second rack 261 moves with the carriage 26, and at this time, the carriage 26 and the second rack 261 move at the same speed, and the flange 101 and the first gear 24 move at the same speed, and the moving speed of the carriage 26 is greater than the moving speed of the flange 101. The carriage 26, when moving, also gradually shortens its distance from the flange 101, so that the second resilient telescopic rod 27 is compressed and the pressing force of the second arc 23 on the flange 101 increases. Therefore, the pressing force of the first arc plate 22 and the second arc plate 23 can be adaptively increased along with the increase of the shaking amplitude of the flange plate 101, so that the blocking effect of the flange plate 101 during shaking is realized, the shaking amplitude of the flange plate 101 and the pipeline 100 is reduced, the normal transportation of fluid in the pipeline 100 is ensured, meanwhile, the dynamic load on the flange plate 101 cannot be transmitted to the base 1 because the flange plate 101 is not fixed with the limiting frame 21, the connection firmness of the base 1 and the ground is ensured, and the supporting effect of the base 1 on the pipeline 100 and the flange plate 101 is ensured.
The pushing assembly 3 comprises two slide frames 31 and bolts 32, the slide frames 31 are bilaterally symmetrical, and the slide frames 31 are slidably mounted on the base 1 along the left-right direction.

The bolt 32 is matched with the nut 322, so that the two sliding frames 31 are movably connected together, and the opposite movement of the two sliding frames 31 is avoided; the position of the restricting frame 21 is appropriately defined, and the restricting frame 21 is prevented from being separated from the slide frame 31.
In winter, the surface of the pipe 100 is easily frozen, so that the weight of the pipe 100 is increased, and thus the joint of the two flanges 101 tends to tilt up, and if not treated, the pipe 100 may leak, so that the invention provides embodiment 2.
Embodiment 2 with continued reference to fig. 5 to 7 on the basis of embodiment 1, the base 1 comprises a base 11 and a stage 12. The base 11 is placed on the ground, and the carrier 12 is located above the base 11 and is elastically and slidably connected with the base 11 along the vertical direction. Specifically, the carrier 12 is provided with a center hole penetrating up and down, and the base 11 is provided with a center rod 13 extending vertically and penetrating up through the center hole. It should be noted that, the diameter of the center hole is larger than the center rod 13, and the center hole is coaxial with the center rod 13, the top end of the center hole is embedded with the top cover 121, the bottom end of the center hole is embedded with the bottom cover 122, the top cover 121 and the bottom cover 122 are both provided with inner holes communicated with the center hole, the diameter of the inner holes is smaller than the center hole, and the inner holes are used for passing through the center rod 13. A return spring 14 is arranged between the carrier 12 and the base 11, the return spring 14 is sleeved on the outer peripheral side of the center rod 13, the bottom end of the return spring 14 is fixedly connected with the base 11, and the top end of the return spring 14 is fixedly connected with the carrier 12 through a bottom cover 122.

The second gear 15 is sleeved on the central rod 13 and can spirally move around the axis of the central rod 13, specifically, the chemical pipeline supporting structure further comprises a one-way bearing 16 arranged between the central rod 13 and the second gear 15, a spiral groove is formed in the outer peripheral surface of the central rod 13, a spiral push rod matched in the spiral groove is arranged on the inner ring of the one-way bearing 16, and the outer ring of the one-way bearing 16 is fixedly connected with the second gear 15.
Two sliding cavities corresponding to the two sliding frames 31 one by one are arranged in the carrying platform 12, the sliding cavities extend along the left-right direction, the sliding frames 31 are L-shaped as a whole, and the bottoms of the sliding frames 31 are in sliding fit in the corresponding sliding cavities.

When the pipe 100 is frozen, the weight of the pipe 100 increases, and the pipe 100 is lowered onto the ballast table 12 through the transmission of the limiting frame 21 and the sliding frame 31, and the carrier 12 drives the second gear 15 and the one-way bearing 16 to move downward. The inner ring of the one-way bearing 16 also rotates when it moves down in cooperation with the helical pushrod and the helical groove. Due to the structural limitation of the unidirectional bearing 16, the inner ring of the unidirectional bearing 16 drives the outer ring of the unidirectional bearing 16 and the second gear 15 to synchronously rotate when rotating.
Then, the second gear 15 drives the two sliding frames 31 to approach each other through the two third racks 311, and the two sliding frames 31 press the two limiting frames 21 in the middle to the inner side. Then, the restricting frame 21 slides and further compresses the first elastic expansion link 25, and the pressure of the first arcuate plate 22 acting on the flange 101 further increases. Simultaneously, the limiting frame 21 drives the first rack 213 to slide, the first rack 213 drives the first gear 24 to rotate, the first gear 24 drives the sliding frame 26 to slide towards the flange 101 through the second rack 261, the sliding frame 26 further compresses the second elastic telescopic rod 27, and the pressure of the second arc-shaped plate 23 acting on the flange 101 is further increased. Therefore, the pressing force of the two flanges 101 in the left and right directions is enhanced, so that the reliability of the joint of the two flanges 101 is ensured, the mutual tilting of the two flanges 101 is avoided, the leakage of fluid in the pipeline 100 is avoided, and the reliable use of the pipeline 100 is ensured.
Referring to fig. 1 to 7, the implementation flow of the present invention is:
First, the two pipes 100 are aligned so that the flanges 101 of the two pipes 100 are connected together. Next, the base 1 is placed directly under the two flanges 101. Then, the two limiting frames 21 are buckled at the positions of the flanges 101 through the arc-shaped grooves 211, at this time, the two flanges 101 are positioned between the first arc-shaped plate 22 and the second arc-shaped plate 23 of the limiting frames 21, and the two limiting frames 21 are opposite to each other in front and back, and are staggered from each other in the left-right direction. Then, the bottoms of the two slide frames 31 are slidably mounted in the respective slide chambers, respectively. Subsequently, two bolts 32 are taken, the bolts 32 are sequentially slid through the two slide frames 31 and the corresponding through holes in the left-right direction, the two slide frames 31 are movably connected together by the bolts 32 through the cooperation with the nuts 322, and the bolts 32 realize proper limitation of the positions of the limiting frames 21 through the cooperation with the through holes.
Thereafter, the distance between the two slide frames 31 can be shortened by the bolts 32 and the nuts 322. The two slide frames 31 push the two limiting frames 21 to approach each other until the first arc-shaped plate 22 abuts against one of the flange plates 101, and a gap exists between the second arc-shaped plate 23 and the other flange plate 101 at the moment, so that the initial distance between the first arc-shaped plate 22 and the second arc-shaped plate 23 is larger than the stacking thickness of the two flange plates 101, and the first arc-shaped plate 22 and the second arc-shaped plate 23 can be respectively located on two sides of the two flange plates 101 when the limiting frames 21 are buckled on the flange plates 101. Thus, the preliminary installation of the chemical pipeline supporting structure is completed.
Next, the distance between the two slide frames 31 is further shortened by the bolts 32 and the nuts 322, the two restricting frames 21 are further moved closer to each other, the first elastic expansion link 25 is compressed, and the first arcuate plate 22 starts to press against the contacted flange 101. At the same time, the restricting frame 21 drives the carriage 26 to move toward the flange 101 through the first rack 213, the first gear 24, and the second rack 261. The second arc-shaped plate 23 moves along with the flange plate 101, when the carriage 26 continues to move after the second arc-shaped plate 23 presses against the other flange plate 101, the second elastic telescopic rod 27 is compressed, and the second arc-shaped plate 23 starts to press against the other flange plate 101. It should be noted that when the two sliding frames 31 are close to each other, the two third racks 311 are also close to each other, and the third racks 311 drive the second gear 15 to rotate, at this time, due to the structural limitation of the unidirectional bearing 16, the rotation of the second gear 15 cannot be transmitted to the inner ring of the unidirectional bearing 16, that is, the inner ring of the unidirectional bearing 16 does not rotate at this time, and therefore the second gear 15 cannot be affected by the spiral push rod and the spiral groove to move downwards.
When the pipe 100 and the flange 101 shake left and right due to the external force, the flange 101 pushes the first arc 22 to slide, and the limiting frame 21 cannot move along the first arc 22 in the same direction under the stop of the sliding frame 31. The first elastic expansion link 25 is continuously compressed, and the pressing force of the first arcuate plate 22 against the flange 101 is further increased. Meanwhile, the first arc 22 drives the first gear 24 to slide, and the first gear 24 rotates under the meshing action of the first rack 213. The first gear 24 moving while rotating drives the second rack 261 to move, and the moving speed of the second rack 261 is greater than the moving speed of the first gear 24 under the limitation of the meshing relationship. Thus, the moving speed of the carriage 26 at this time is greater than the moving speed of the flange 101, i.e., the carriage 26 gradually approaches the flange 101 when moving. The second resilient telescopic rod 27 is further compressed and the second arcuate plate 23 is further compressed against the flange 101. Further compression of the first arcuate plate 22 and the second arcuate plate 23 can adaptively resist lateral rocking of the flange 101, reducing the amplitude of rocking of the flange 101.
In winter, the surface of the pipe 100 is frozen with ice, and thus the weight increases. The carrier 12 moves downwards under the gravity of the pipe 100 and the flange 101, and the second gear 15 and the one-way bearing 16 move downwards. Under the cooperation of the spiral push rod and the spiral groove, the unidirectional bearing 16 also rotates when moving downwards, and further drives the second gear 15 to rotate. The second gear 15 drives the two limiting frames 21 to approach each other through the two third racks 311 and the two slide frames 31. The limiting frame 21 further compresses the first elastic telescopic rod 25, and the pressing force of the first arc-shaped plate 22 on the flange plate 101 is further increased, so that the pressing effect of the first arc-shaped plate 22 on the flange plate 101 is improved. Simultaneously, the limiting frame 21 drives the sliding frame 26 to continuously slide towards the flange plate 101 through the first rack 213, the first gear 24 and the second rack 261, the sliding frame 26 further compresses the second elastic telescopic rod 27, and the pressing force of the second arc-shaped plate 23 on the flange plate 101 is further increased, so that the pressing effect of the second arc-shaped plate 23 on the flange plate 101 is improved. Therefore, the pressing force of the two flanges 101 in two directions is enhanced, so that the two flanges 101 are prevented from tilting mutually, and the leakage of fluid in the pipeline 100 is avoided.
