Description

Technical Field

[0001] This invention relates to the field of equipment manufacturing technology, and in particular to an automatic docking and locking device for steel cylinder pipelines. Background Technology

[0002] Currently, most pipeline connection equipment involves manual operation, with floating connections made in one direction. This places extremely high demands on equipment precision and installation accuracy, leading to stagnant costs, low assembly efficiency, and insufficient precision. The connection between the tank and the press is a crucial step, involving both upper and lower connections to ultimately link the tank, flexible connecting pipes, and press together. This particular tank weighs 600kg. Currently, this connection method requires manual operation, which is complex, involves installing numerous components, poses safety risks, and results in poor sealing, potentially leading to product defects. Summary of the Invention

[0003] To address the aforementioned shortcomings, this invention proposes an automatic cylinder pipeline docking and locking device. By integrating multiple functional modules such as a self-locking mechanism, an adaptive adjustment mechanism, a Y-axis correction mechanism, an X-axis correction mechanism, and a pressure buffer mechanism, it achieves fully automated operation of the cylinder pipeline from docking to locking, which not only improves work efficiency but also significantly reduces the danger of manual operation.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic cylinder pipeline docking and locking device, comprising:

[0005] Cylinder piping: Cylinder piping includes tank piping located at the lower end of the tank, flexible connection pipes, and press piping located at the upper end of the press;

[0006] Locking device: The locking device includes a self-locking mechanism connecting one end of the tank pipe and the flexible connecting pipe, and the other end of the press pipe and the flexible connecting pipe, an adaptive adjustment mechanism arranged sequentially along the direction of the flexible connecting pipe, a first mounting platform, a Y-axis correction mechanism, a second mounting platform, an X-axis correction mechanism, a third mounting platform, a pressure buffer mechanism, and a fourth mounting platform;

[0007] The self-locking mechanism includes mounting blocks on both sides of the tank pipe and the flexible connection pipe. The upper self-locking mechanism is connected to both sides of the adaptive adjustment mechanism through the mounting blocks, and the lower self-locking mechanism is located at the upper end of the fourth installation platform.

[0008] The Y-axis correction mechanism is located between the first mounting platform and the second mounting platform and is connected to the adaptive adjustment mechanism through the first mounting platform; the X-axis correction mechanism is located between the second mounting platform and the third mounting platform and is connected to the Y-axis correction mechanism through the second mounting platform.

[0009] The pressure buffer mechanism is located between the third and fourth mounting platforms and is connected to the X-axis correction mechanism via the third mounting platform.

[0010] As an improvement, the adaptive adjustment mechanism includes a movable adjustment plate, a mounting platform, an X-direction adjustment structure located at the front and rear ends of the mounting platform, and a Y-direction adjustment structure located on both sides of the mounting platform. The mounting platform is connected to the movable adjustment plate via the upwardly extending Y-direction adjustment structure. The upper end of the movable adjustment plate is rotatably connected to the Y-direction adjustment structure, allowing the movable adjustment plate to rotate relative to the mounting platform in the Y direction to adjust the tilt angle of the movable adjustment plate in the Y direction. The upper end of the first mounting platform protrudes from the X-direction adjustment structure, and the mounting platform is rotatably connected to the mounting plate via the upwardly extending X-direction adjustment structure, allowing the mounting platform to rotate relative to the mounting platform in the X direction. This causes the movable adjustment plate to drive the mounting platform to adjust its tilt angle in the X direction via the Y-direction adjustment structure, thereby achieving parallel docking between the movable adjustment plate and the tank pipeline.

[0011] As an improvement, the X-direction adjustment structure includes a first rotating shaft, a first bearing mounting base, and a rolling bearing. The first bearing mounting base is provided with a first bearing mounting hole. The outer peripheral wall of the rolling bearing is connected to the inner wall of the first bearing mounting hole. The inner peripheral wall of the rolling bearing is connected to one end of the first rotating shaft. The mounting plate is provided with a rotating shaft mounting hole inside. The other end of the first rotating shaft is connected to the rotating shaft mounting hole.

[0012] As an improvement, the Y-direction adjustment structure includes a second rotating shaft, a second bearing mounting seat, and a rolling bearing. Mounting holes are provided on both sides of the movable adjustment plate corresponding to the upper end of the second bearing mounting seat. The upper end of the second bearing mounting seat is exposed inside the mounting holes. The second bearing mounting seat has a second bearing mounting hole. The outer peripheral wall of the rolling bearing is connected to the inner wall of the second bearing mounting hole. The middle part of the second rotating shaft is connected to the inner peripheral wall of the rolling bearing. A rotating shaft mounting groove is provided on the side wall of the mounting hole corresponding to the second rotating shaft. Both sides of the second rotating shaft are fixedly connected to the rotating shaft mounting groove.

[0013] As an improvement, the Y-axis correction mechanism includes correction structures disposed on both sides of the first mounting platform and the second mounting platform, and a guide structure disposed on one side of the correction structures; the X-axis correction mechanism includes correction structures disposed at the front and rear ends of the second mounting platform and the third mounting platform, and a guide structure disposed at one end of the correction structures.

[0014] As an improvement, the correction structure includes a lower correction block connected to the upper end of the second mounting platform and the upper end of the third mounting platform, several upper correction blocks connected to the lower end of the first mounting platform and the lower end of the second mounting platform, a connecting shaft, and a correction spring surrounding the outer peripheral wall of the connecting shaft. The several upper correction blocks are disposed on both sides of the lower correction block and connected to the lower correction block through the connecting shaft. One side of the correction spring abuts against the side wall of the upper correction block, and the other side of the correction spring abuts against the side wall of the lower correction block.

[0015] As an improvement, the guide structure includes a slider connected to the lower end of the first mounting platform and the lower end of the second mounting platform, and a guide rail connected to the upper end of the second mounting platform and the upper end of the third mounting platform. The slider is provided with a groove that matches the guide rail.

[0016] As an improvement, a self-locking mechanism is provided on several cylinders on both sides of the tank pipe and the flexible connection pipe, and the press pipe and the flexible connection pipe, a push rod is provided on the side of the cylinder near the tank pipe, and a clamping structure is provided on the other side of the push rod. The mounting block is provided on the side of the cylinder near the tank pipe. The cylinder drives the push rod so that the clamping structure abuts against the outer peripheral wall of the connection between the tank pipe and the flexible connection pipe, and the connection between the press pipe and the flexible connection pipe.

[0017] As an improvement, the clamping structure includes a first movable arm, a second movable arm, and a fixing block adapted to the outer wall of the flexible connecting pipe, arranged symmetrically. One side of the first movable arm is hinged to a push rod, the other side of the first movable arm is hinged to one side of the second movable arm, and the other side of the second movable arm is hinged to one side of the fixing block. The cylinder drives the push rod so that the other side of the fixing block abuts against the outer peripheral wall of the connection between the clamping structure and the tank pipe and the flexible connecting pipe, and the connection between the press pipe and the flexible connecting pipe.

[0018] As an improvement, the pressure buffer mechanism includes guide posts located at the four corners of the third mounting platform, linear bearings with flanges, and buffer springs surrounding the outer periphery of the guide posts. The lower end of the flange abuts against the third mounting platform, and the linear bearings are sleeved and installed on the outer periphery of the guide posts such that the lower end of the linear bearing abuts against one end of the buffer spring, and the lower end of the buffer spring abuts against the upper end of the guide posts.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] (1) The equipment integrates multiple functional modules such as self-locking mechanism, adaptive adjustment mechanism, Y-axis correction mechanism, X-axis correction mechanism and pressure buffer mechanism to realize the fully automated operation of the gas cylinder pipeline from connection to locking. This highly integrated design not only improves work efficiency, but also significantly reduces the complexity and error rate of manual operation.

[0021] (2) The design of the adaptive adjustment mechanism includes a movable adjustment plate and a mounting platform, as well as X-direction adjustment structures and Y-direction adjustment structures respectively set at the front and rear ends of the mounting platform. This allows the entire locking device to be flexibly adjusted according to different directions and angles when connecting pipes. When the Y-direction needs to be adjusted, the two sides of the second rotating shaft are fixedly connected to the rotating shaft mounting groove, and the middle of the second rotating shaft is connected to the inner circumferential wall of the rolling bearing. The second rotating shaft rotates relative to the second bearing mounting seat, thus causing the movable adjustment plate to rotate relative to the mounting platform in the Y-direction. When the X-direction needs to be adjusted, the movable adjustment plate rotates in the same direction as the first rotating shaft, causing the second rotating shaft and the second bearing mounting seat to rotate in the direction of the movable adjustment plate. Since the mounting platform is rotatably connected to the mounting plate through the first rotating shaft and the rolling bearing, the mounting platform can rotate relative to the mounting plate in the X-direction. At the same time, the mounting platform is connected to the movable adjustment plate through the second rotating shaft and the second bearing mounting seat, causing the movable adjustment plate to drive the mounting platform to rotate to adjust the X-direction. Through these two correction mechanisms, the position and direction of the pipe can be finely adjusted to achieve the best docking effect. This is especially important for equipment that needs to be docked, ensuring the stability and reliability of the connection.

[0022] (3) When the correction structure is not subjected to external force, the correction spring is in its natural state, and its elastic force acts in a balanced manner between the upper and lower correction blocks. The upper correction block is connected to the lower correction block through a connecting shaft, forming a certain range of motion, but it will not move arbitrarily due to the elastic force of the correction spring. When the first or second mounting platform is subjected to external force relative to the Y-axis correction mechanism in the Y direction, or the second or third mounting platform is subjected to external force relative to the X-axis correction mechanism in the X direction, the mounting platform will undergo a slight displacement. This displacement will be transmitted to the upper correction block connected to it, causing the upper correction block to move relative to the lower correction block. As the upper correction block moves, the correction spring is compressed or stretched, and its elastic force... When the force changes, the spring force of the correction spring resists this displacement, attempting to restore the upper and lower correction blocks to their initial relative positions. Under the action of the spring force, the upper correction block moves along the direction of the connecting shaft, while the connected mounting platform is fine-tuned. This fine-tuning is continuous until the upper and lower correction blocks return to their initial positions. When the correction process is completed, the spring force of the correction spring reaches a new equilibrium with the external force, and the position of the mounting platform is accurately corrected. The change in the spring force of the correction spring can cause the upper and lower correction blocks to move precisely, thereby correcting the position of the lower flange at the upper end of the flexible connecting pipe. The spring force of the correction spring can resist external interference and maintain the stability of the mounting platform position.

[0023] (4) When the first or second mounting platform needs to be fine-tuned in the Y-axis direction, the slider slides along the guide rail. This sliding is smooth and controllable, ensuring that the movement of the mounting platform in the Y-axis direction is along the predetermined path. When the second or third mounting platform needs to be fine-tuned in the X-axis direction, the slider also slides along the guide rail, ensuring the smoothness and accuracy of the movement. Through the close cooperation between the slider and the guide rail, the stability of the mounting platform during the movement is significantly enhanced, reducing displacement errors caused by vibration or external interference.

[0024] (5) The clamping structure adopts a symmetrically arranged first and second movable arms, and a fixed block hinged to them. This design allows the clamping structure to be flexibly adjusted according to the actual size and shape of the tank pipe and flexible connection pipe, and the press pipe and flexible connection pipe. When the cylinder drives the push rod to move, the first and second movable arms will rotate accordingly, thereby driving the fixed block to tightly adhere to the outer circumferential wall of the pipe, realizing the tight clamping of pipes of different diameters and shapes, and improving the sealing performance of the connection between the tank pipe and flexible connection pipe, and the press pipe and flexible connection pipe.

[0025] (6) Since the tank weighs 600 kg, when the tank pipes are connected to the flexible connecting pipes and the press pipes, and when the third installation platform or other connected components are subjected to downward pressure, this pressure will be transmitted to the linear bearing. Due to the certain friction between the linear bearing and the guide column, this pressure will first cause the linear bearing to move downward a small distance along the guide column until the pressure overcomes the elastic force of the buffer spring. As the pressure continues to increase, the linear bearing begins to compress the buffer spring. In this process, the buffer spring resists the downward pressure through its elastic force, thereby slowing down the descent speed of the third installation platform. The elastic force of the buffer spring is proportional to the amount of compression. Therefore, as the amount of compression increases, the elastic force also gradually increases, providing greater resistance to counteract the downward pressure. When the pressure reaches a certain level, the spring force of the buffer spring reaches a balance with the downward pressure. At this point, the third mounting platform will no longer continue to descend, but will remain in a relatively stable position. In this stable state, the buffer spring still maintains a certain amount of compression to provide continuous support and buffering. When the external pressure decreases or disappears, the spring force of the buffer spring will begin to push the linear bearing upward, gradually returning to the initial state. During this process, the spring force of the buffer spring is gradually released until the linear bearing completely returns to its initial position and is tightly pressed against the third mounting platform. Through the action of the spring force, the pressure buffer mechanism can prevent damage caused by excessive pressure above and rigid connection of the overall structure, and also avoid the non-uniqueness of the external dimensions of the upper tank, thus absorbing the errors.

[0034] like Figure 1 As shown, an automatic docking and locking device for gas cylinder pipelines is disclosed. The gas cylinder pipeline 1 includes a tank pipeline 1.1 located at the lower end of the tank body, a flexible connecting pipe 1.2, and a press pipeline 1.3 located at the upper end of the press. The lower end of the tank pipeline 1.1 is provided with an upper flange, the upper end of the flexible connecting pipe 1.2 is provided with a lower flange, and the upper end of the press pipeline 1.3 is provided with a lower flange. A sealing gasket is provided between the upper flange and the lower flange.

[0035] The locking device includes a self-locking mechanism 2 connecting one end of the tank pipe 1.1 and the flexible connecting pipe 1.2, and the other end of the press pipe 1.3 and the flexible connecting pipe 1.2; an adaptive adjustment mechanism 3 arranged sequentially along the direction of the flexible connecting pipe 1.2; a first mounting platform 4; a Y-axis correction mechanism; a second mounting platform 5; an X-axis correction mechanism; a third mounting platform 6; a pressure buffer mechanism 7; and a fourth mounting platform 8. The self-locking mechanism 2 includes mounting blocks 2.1 located on both sides of the tank pipe 1.1 and the flexible connecting pipe 1.2, and the self-locking mechanism 2 at the upper end and the adaptive adjustment mechanism 3. The two sides of the mechanism 3 are connected by mounting blocks 2.1. The self-locking mechanism 2 at the lower end is set at the upper end of the fourth mounting platform 8. The pressure buffer mechanism 7 is set between the third mounting platform 6 and the fourth mounting platform 8 and is connected to the X-axis correction mechanism through the third mounting platform 6. The Y-axis correction mechanism is set between the first mounting platform 4 and the second mounting platform 5 and is connected to the adaptive adjustment mechanism 3 through the first mounting platform 4. The X-axis correction mechanism is set between the second mounting platform 5 and the third mounting platform 6 and is connected to the Y-axis correction mechanism through the second mounting platform 5.

[0036] like Figure 2As shown, the adaptive adjustment mechanism 3 includes a movable adjustment plate 3.1, a mounting platform 3.2, an X-direction adjustment structure 3.3 located at the front and rear ends of the mounting platform 3.2, and Y-direction adjustment structures 3.4 located on both sides of the mounting platform 3.2. The mounting platform 3.2 is connected to the movable adjustment plate 3.1 via the upwardly extending Y-direction adjustment structures 3.4. The upper ends of the movable adjustment plate 3.1 and the Y-direction adjustment structures 3.4 are rotatably connected so that the movable adjustment plate 3.1 rotates relative to the mounting platform 3.2 in the Y direction to adjust the movable adjustment plate 3.1. .1 At the tilt angle in the Y direction, the upper end of the first mounting platform 4 is provided with a mounting plate 4.1 protruding from the X-direction adjustment structure 3.3. The mounting platform 3.2 is rotatably connected to the mounting plate 4.1 through the upwardly extending X-direction adjustment structure 3.3 so that the mounting platform 3.2 rotates relative to the mounting platform 3.2 in the X direction. This allows the movable adjustment plate 3.1 to drive the mounting platform 3.2 to adjust its tilt angle in the X direction through the Y-direction adjustment structure 3.4, so as to achieve parallel docking between the movable adjustment plate 3.1 and the tank pipe 1.1.

[0037] The X-direction adjustment structure 3.3 includes a first rotating shaft 3.3.1, a first bearing mounting seat 3.3.2, and a rolling bearing 3.5. The first bearing mounting seat 3.3.2 is provided with a first bearing mounting hole 3.3.3. The outer peripheral wall of the rolling bearing 3.5 is connected to the inner wall of the first bearing mounting hole 3.3.3. The inner peripheral wall of the rolling bearing 3.5 is connected to one end of the first rotating shaft 3.3.1. The mounting plate 4.1 is provided with a rotating shaft mounting hole 4.1.1. The other end of the first rotating shaft 3.3.1 is connected to the rotating shaft mounting hole 4.1.1.

[0038] The Y-direction adjustment structure 3.4 includes a second rotating shaft 3.4.1, a second bearing mounting seat 3.4.2, and a rolling bearing 3.5. The movable adjustment plate 3.1 has mounting holes 3.1.1 on both sides corresponding to the upper end of the second bearing mounting seat 3.4.2. The upper end of the rolling bearing 3.5 mounting seat is exposed inside the mounting holes 3.1.1. The second bearing mounting seat 3.4.2 has a second bearing mounting hole 3.4.3. The outer peripheral wall of the rolling bearing 3.5 is connected to the inner wall of the second bearing mounting hole 3.4.3. The middle part of the second rotating shaft 3.4.1 is connected to the inner peripheral wall of the rolling bearing 3.5. The side wall of the mounting hole 3.1.1 has a rotating shaft mounting groove 3.1.2 corresponding to the second rotating shaft 3.4.1. Both sides of the second rotating shaft 3.4.1 are fixedly connected to the rotating shaft mounting groove 3.1.2.

[0039] like Figure 3 As shown, the Y-axis correction mechanism includes correction structures 9 disposed on both sides of the first mounting platform 4 and the second mounting platform 5, and a guide structure 10 disposed on one side of the correction structure 9. The X-axis correction mechanism includes correction structures 9 disposed at the front and rear ends of the second mounting platform 5 and the third mounting platform 6, and a guide structure 10 disposed at one end of the correction structure 9.

[0040] The correction structure 9 includes a lower correction block 9.1 connected to the upper end of the second mounting platform 5 and the upper end of the third mounting platform 6, several upper correction blocks 9.2 connected to the lower end of the first mounting platform 4 and the lower end of the second mounting platform 5, a connecting shaft 9.3, and a correction spring 9.4 surrounding the outer peripheral wall of the connecting shaft 9.3. The several upper correction blocks 9.2 are disposed on both sides of the lower correction block 9.1 and connected to the lower correction block 9.1 through the connecting shaft 9.3. One side of the correction spring 9.4 abuts against the side wall of the upper correction block 9.2, and the other side of the correction spring 9.4 abuts against the side wall of the lower correction block 9.1.

[0041] The guide structure 10 includes a slider 10.1 connected to the lower end of the first mounting platform 4 and the lower end of the second mounting platform 5, and a guide rail 10.2 connected to the upper end of the second mounting platform 5 and the upper end of the third mounting platform 6. The slider 10.1 is provided with a groove 10.1.1 adapted to the guide rail 10.2.

[0042] like Figure 4 As shown, the self-locking mechanism 2 includes several cylinders 2.2 on both sides of the tank pipe 1.1 and flexible connecting pipe 1.2, and the press pipe 1.3 and flexible connecting pipe 1.2; a push rod 2.3 on the side of the cylinder 2.2 near the tank pipe 1.1; and a clamping structure 2.4 on the other side of the push rod 2.3. The mounting block 2.1 is located on the side of the cylinder 2.2 near the tank pipe 1.1. The cylinder 2.2 drives the push rod 2.3 so that the clamping structure 2.4 abuts against the outer peripheral wall of the connection between the tank pipe 1.1 and flexible connecting pipe 1.2, and the connection between the press pipe 1.3 and flexible connecting pipe 1.2.

[0043] The clamping structure 2.4 includes a first movable arm 2.4.1, a second movable arm 2.4.2, and a fixing block 2.4.3 adapted to the outer wall of the flexible connecting pipe 1.2, arranged symmetrically. One side of the first movable arm 2.4.1 is hinged to the push rod 2.3, the other side of the first movable arm 2.4.1 is hinged to one side of the second movable arm 2.4.2, and the other side of the second movable arm 2.4.2 is hinged to one side of the fixing block 2.4.3. The cylinder 2.2 drives the push rod 2.3 so that the other side of the fixing block 2.4.3 abuts against the outer peripheral wall of the connection between the clamping structure 2.4 and the tank pipe 1.1 and the flexible connecting pipe 1.2, and the connection between the press pipe 1.3 and the flexible connecting pipe 1.2.

[0044] The fixing block 2.4.3 has a fixing groove on the side facing the flexible connecting pipe 1.2, and the upper flange, sealing gasket, and lower flange are embedded in the fixing groove.

[0045] like Figure 5As shown, the pressure buffer mechanism 7 includes guide posts 7.1 located at the four corners of the third mounting platform 6, linear bearings 7.2 with flange faces 7.2.1, and buffer springs 7.3 surrounding the outer periphery of the guide posts 7.1. The lower end of the flange face 7.2.1 abuts against the third mounting platform 6. The linear bearings 7.2 are sleeved and installed on the outer periphery of the guide posts 7.1 such that the lower end of the linear bearings 7.2 abuts against one end of the buffer springs 7.3, and the lower end of the buffer springs 7.3 abuts against the upper end of the guide posts 7.1.

[0046] When the lower end of the flexible connector 1.2 is connected to the upper end of the press pipe 1.3, the cylinder 2.2 of the lower end self-locking mechanism 2 drives the first movable arm 2.4.1 and the second movable arm 2.4.2 to rotate via the push rod 2.3, thereby driving the fixed block 2.4.3. This causes the sealing gasket between the upper flange at the lower end of the flexible connector 1.2, the lower flange at the upper end of the press pipe 1.3, and one side of the sealing gasket between the upper flange at the lower end of the flexible connector 1.2 and the lower flange at the upper end of the press pipe 1.3 to be embedded in the fixed groove, thus sealing the lower end of the flexible connector 1.2 with the upper end of the press pipe 1.3. When the upper flange at the lower end of the tank pipe 1.1 is connected to the lower flange at the upper end of the flexible connector 1.2, the lower end of the tank pipe 1.1 presses against the movable adjusting plate 3.1. To ensure that the movable adjusting plate 3.1 and the tank pipe 1.1 are parallel, when the Y direction needs to be adjusted, the two sides of the second rotating shaft 3.4.1 are mounted with the rotating shaft. The groove 3.1.2 is fixedly connected. The middle part of the second rotating shaft 3.4.1 is connected to the inner peripheral wall of the rolling bearing 3.5. The second rotating shaft 3.4.1 rotates relative to the second bearing mounting seat 3.4.2, thus causing the movable adjusting plate 3.1 to rotate relative to the mounting platform 3.2 in the Y direction. When it is necessary to adjust the X direction, the movable adjusting plate 3.1 rotates in the same direction as the first rotating shaft 3.3.1, causing the second rotating shaft 3.4.1 and the second bearing mounting seat 3.4.2 to rotate with the movable adjusting plate 3.1. Since the mounting platform 3.2 is rotatably connected to the mounting plate 4.1 through the first rotating shaft 3.3.1 and the rolling bearing 3.5, the mounting platform 3.2 can rotate relative to the mounting plate 4.1 in the X direction. At the same time, the mounting platform 3.2 is connected to the movable adjusting plate 3.1 through the second rotating shaft 3.4.1 and the second bearing mounting seat 3.4.2, causing the movable adjusting plate 3.1 to drive the mounting platform 3.2 to rotate to adjust the X direction.

[0047] When the upper flange at the lower end of the tank pipe 1.1 and the lower flange at the upper end of the flexible connecting pipe 1.2 are misaligned, the upper correction block 9.2 moves relative to the lower correction block 9.1. As the upper correction block 9.2 moves, the correction spring 9.4 is compressed or stretched, and its elastic force changes. The elastic force of the correction spring 9.4 resists this displacement, restoring the upper correction block 9.2 and the lower correction block 9.1 to their initial relative positions. Under the action of the elastic force of the correction spring 9.4, when the first mounting platform 4 or the second mounting platform 5 needs to be fine-tuned in the Y-axis direction, or when the second mounting platform 5 or the third mounting platform 6 needs to be fine-tuned in the X-axis direction, the slide groove 10.1.1 of the slider 10.1 slides along the guide rail 10.2, causing the upper correction block 9.2 to move along the direction of the connecting shaft 9.3. At the same time, the mounting platform connected to it is fine-tuned until the upper correction block 9.2 moves along the direction of the connecting shaft 9.3. Correction block 9.2 and lower correction block 9.1 return to their initial positions. After the correction process is completed, the elastic force of correction spring 9.4 and the external force reach a new equilibrium state, and the position of the installation platform is accurately corrected, thereby correcting the position of the lower flange at the upper end of flexible connecting pipe 1.2. When the upper flange at the lower end of tank pipe 1.1 and the lower flange at the upper end of flexible connecting pipe 1.2 are connected, the cylinder 2.2 of the upper self-locking mechanism 2 drives the first movable arm 2.4.1 and the second movable arm 2.4.2 to rotate through the push rod 2.3, thereby driving the fixed block 2.4.3, so that one side of the sealing gasket between the upper flange at the lower end of tank pipe 1.1, the lower flange at the upper end of flexible connecting pipe 1.2, and the lower flange at the upper end of flexible connecting pipe 1.2 is embedded in the fixed groove, so that the lower end of tank pipe 1.1 and the upper end of flexible connecting pipe 1.2 are sealed together.

[0048] When the lower end of the tank pipe 1.1 is pressed down, the third mounting platform 6 or other components connected to it are subjected to downward pressure. This pressure is transmitted to the linear bearing 7.2. Due to the friction between the linear bearing 7.2 and the guide post 7.1, this pressure initially causes the linear bearing 7.2 to move downward a small distance along the guide post 7.1 until the pressure overcomes the elastic force of the buffer spring 7.3. As the pressure continues to increase, the linear bearing 7.2 begins to compress the buffer spring 7.3. During this process, the buffer spring 7.3 resists the downward pressure through its elastic force, thereby slowing down the descent speed of the third mounting platform 6. The elastic force of the buffer spring 7.3 is proportional to the amount of compression; therefore, as the amount of compression increases, the elastic force gradually increases, providing greater resistance to the downward pressure. When the pressure reaches a certain level... When the pressure reaches a certain level, the elastic force of the buffer spring 7.3 reaches a balance with the downward pressure. At this point, the third mounting platform 6 will no longer continue to descend, but will remain in a relatively stable position. In this stable state, the buffer spring 7.3 still maintains a certain amount of compression to provide continuous support and buffering. When the external pressure decreases or disappears, the elastic force of the buffer spring 7.3 will begin to push the linear bearing 7.2 upward, gradually returning to the initial state. During this process, the elastic force of the buffer spring 7.3 is gradually released until the linear bearing 7.2 completely returns to its initial position and is tightly pressed against the third mounting platform 6. Through the elastic force of the buffer spring 7.3, the pressure buffer mechanism 7 can avoid damage caused by excessive pressure above and rigid connection of the overall structure, and also avoid the non-uniqueness of the appearance dimensions of the upper tank, thus absorbing the errors.

Any non-substantial improvements made using the technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
