One side of the correction spring is against the side wall of the upper correction block, and the other side of the correction spring is 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.

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

[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 full automation operation of cylinder pipeline from docking 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 an X-direction adjustment structure and a Y-direction adjustment structure respectively arranged at the front and rear ends of the mounting platform, so that the entire locking device can be flexibly adjusted according to the requirements of different directions and angles when connecting the pipeline. 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, the middle part of the second rotating shaft is connected to the inner peripheral wall of the rolling bearing, and the second rotating shaft rotates relative to the second bearing mounting seat, so that the movable adjustment plate rotates relative to the mounting platform along 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, so that the second rotating shaft and the second bearing mounting seat rotate along the rotation 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 along 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, so that the movable adjustment plate drives the mounting platform to rotate to adjust the X direction. Through these two correction mechanisms, the position and direction of the pipeline can be fine-tuned to achieve the best docking effect, which is particularly 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 a natural state, and its elastic force acts in a balanced manner between the upper correction block and the lower correction block. The upper correction block is connected to the lower correction block through a connecting shaft to form a certain range of motion, but is limited by the elastic force of the correction spring and will not move at will. When the first mounting platform or the second mounting platform is subjected to external force in the Y direction for the Y-axis correction mechanism, or the second mounting platform or the third mounting platform is subjected to external force in the X direction for the X-axis correction mechanism, the mounting platform will undergo a slight displacement, which will be transmitted to the upper correction block connected thereto, 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 is increased. When the force changes, the elastic force of the correction spring will resist this displacement and try to restore the upper correction block and the lower correction block to their initial relative positions. Under the elastic force of the correction spring, the upper correction block moves along the direction of the connecting axis, and the mounting platform connected thereto is fine-tuned at the same time. This fine-tuning is continuous until the upper correction block and the lower correction block return to their initial positions. When the correction process is completed, the elastic force of the correction spring and the external force reach a new equilibrium state, and the position of the mounting platform is accurately corrected. The change in the elastic force of the correction spring can cause the upper correction block and the lower correction block to move accurately, thereby correcting the position of the lower flange at the upper end of the flexible connecting pipe. The elastic force of the correction spring can resist external interference and maintain the stability of the mounting platform position.

[0023] (4) When the first mounting platform or the second mounting platform needs to be fine-tuned in the Y-axis direction, the slide groove of 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 carried out along a predetermined path. When the second mounting platform or the third mounting platform needs to be fine-tuned in the X-axis direction, the slider also slides along the slide groove of 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 process is significantly enhanced, reducing the displacement error caused by vibration or external interference;

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

[0025] (6) Since the tank weighs 600 kg, when the tank pipe is connected to the flexible connecting pipe and the press pipe, when the third mounting platform or other components connected thereto are subjected to downward pressure, this pressure will be transmitted to the linear bearing. Since there is a certain friction between the linear bearing and the guide column, this pressure will first cause the linear bearing to move downward along the guide column for a small distance until the pressure overcomes the elastic force of the buffer spring. When 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 mounting platform. The elastic force of the buffer spring is proportional to the compression amount. Therefore, as the compression amount increases, the elastic force gradually increases, providing greater resistance to counteract the downward pressure. When the pressure reaches a certain level, the elastic force of the buffer spring and the downward pressure reach a state of equilibrium. At this time, 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 elastic force of the buffer spring will begin to push the linear bearing upward and gradually return to its initial state. During this process, the elastic force of the buffer spring is gradually released until the linear bearing completely returns to its initial position and is tightly against the third mounting platform. Through the elastic force of the buffer spring, the pressure buffer mechanism can avoid damage to the overall structure caused by excessive pressure above and hard links, and also avoid the non-uniqueness of the external dimensions of the upper tank to absorb the errors therein.

[0046] When the lower end of the flexible connecting tube 1.2 is butt-jointed with 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 through the push rod 2.3, thereby driving the fixed block 2.4.3, so that the upper flange at the lower end of the flexible connecting tube 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 connecting tube 1.2 and the lower flange at the upper end of the press pipe 1.3 are embedded in the interior of the fixed groove, so that the lower end of the flexible connecting tube 1.2 is sealed and connected 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 butt-jointed with the lower flange at the upper end of the flexible connecting tube 1.2, the lower end of the tank pipe 1.1 is pressed against the movable adjustment plate 3.1. In order to make the movable adjustment plate 3.1 and the tank pipe 1.1 parallel butt-jointed, when the Y direction needs to be adjusted, the two sides of the second rotating shaft 3.4.1 are connected to the rotating shaft mounting 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, and the second rotating shaft 3.4.1 rotates relative to the second bearing mounting seat 3.4.2, so that the movable adjustment plate 3.1 rotates relative to the mounting platform 3.2 along the Y direction. When the X direction needs to be adjusted, the movable adjustment plate 3.1 rotates in the same direction as the first rotating shaft 3.3.1, so that the second rotating shaft 3.4.1 and the second bearing mounting seat 3.4.2 rotate with the movable adjustment 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 along the X direction. At the same time, the mounting platform 3.2 is connected to the movable adjustment plate 3.1 through the second rotating shaft 3.4.1 and the second bearing mounting seat 3.4.2, so that the movable adjustment plate 3.1 drives 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 connected and relatively offset, 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 will resist this displacement and restore the upper correction block 9.2 and the lower correction block 9.1 to their initial relative positions. Under 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, so that the upper correction block 9.2 moves along the direction of the connecting shaft 9.3, and the mounting platform connected thereto is fine-tuned until the upper correction block 9.2 moves along the connecting shaft 9.3. The correction block 9.2 and the lower correction block 9.1 return to their initial positions. When the correction process is completed, the elastic force of the correction spring 9.4 and the external force reach a new equilibrium state, and the position of the mounting platform is accurately corrected, thereby correcting the position of the lower flange at the upper end of the flexible connecting pipe 1.2. 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 docked, the cylinder 2.2 of the upper end 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 the upper flange at the lower end of the tank pipe 1.1, the lower flange at the upper end of the flexible connecting pipe 1.2, and one side of the sealing gasket between 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 embedded in the interior of the fixed groove, so that the lower end of the tank pipe 1.1 is sealed and connected to the upper end of the flexible connecting pipe 1.2;

[0048] When the lower end of the tank pipe 1.1 is pressed downward, the third mounting platform 6 or other components connected thereto are subjected to downward pressure, and this pressure will be transmitted to the linear bearing 7.2. Since there is a certain friction between the linear bearing 7.2 and the guide column 7.1, this pressure will first cause the linear bearing 7.2 to move downward along the guide column 7.1 for a small distance until the pressure overcomes the elastic force of the buffer spring 7.3. When the pressure continues to increase, the linear bearing 7.2 begins to compress the buffer spring 7.3. In this process, the buffer spring 7.3 resists the downward pressure through its elastic force, thereby slowing down the descending speed of the third mounting platform 6. The elastic force of the buffer spring 7.3 is proportional to the compression amount. Therefore, as the compression amount increases, the elastic force gradually increases, providing greater resistance to counteract the downward pressure. When the pressure reaches a certain value, the linear bearing 7.2 will move downward along the guide column 7.1 for a small distance until the pressure overcomes the elastic force of the buffer spring 7.3. When the third mounting platform 6 reaches a certain level, the elastic force of the buffer spring 7.3 and the downward pressure reach a balanced state. At this time, 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 effect. 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 to move upward and gradually return to its initial state. In 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 against the third mounting platform 6. Through the elastic force of the buffer spring 7.3, the pressure buffer mechanism 7 can avoid damage to the overall structure caused by excessive pressure above and hard connection, and also avoid the non-uniqueness of the external dimensions of the upper tank body to absorb the error therein.

As long as various non-substantial improvements are made using the technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
