Description

Technical Field

[0001] This utility model relates to the field of tube sheet structure technology, and in particular to a split tube sheet. Background Technology

[0002] In industrial equipment, tube sheets are one of the core components of key equipment such as heat exchangers and pressure vessels. Their main function is to support the heat exchange tube bundle and achieve effective isolation between different media. As a key structure connecting the shell side and the tube side, tube sheets not only need to have sufficient mechanical strength to withstand internal fluid pressure, temperature changes and vibration loads during equipment operation, but also need to ensure good sealing performance to prevent leakage between different media, thereby ensuring the safe, stable and efficient operation of the equipment.

[0003] Traditional tube sheets are mostly integrally molded structures. Although they have high overall strength, they have significant limitations in practical applications. On the one hand, integral tube sheets are large in size and heavy in weight, requiring a lot of space and incurring high costs during transportation. This is especially true in complex working conditions or confined working environments, where transportation and hoisting are extremely difficult. On the other hand, the manufacturing and processing of integral tube sheets require high precision equipment, have long processing cycles, and involve complex processes such as welding and heat treatment. Maintenance and replacement often require the entire tube sheet to be fabricated and replaced, resulting in high maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a split tube sheet.

[0005] This utility model is achieved using the following technical solution: a split tube sheet, comprising a tube sheet one and a tube sheet two. Mounting seats are fixedly connected to both sides of the outer surface of the tube sheet one, and a limiting cavity is formed inside the mounting seat. A combination seat is fixedly connected to both sides of the outer surface of the tube sheet two. A transverse spring is fixedly connected to the inner wall of the combination seat. A movable column is fixedly connected to the surface of the transverse spring. Spring grooves are formed on both sides of the movable column. A vertical spring is fixedly connected to the inner wall of the spring groove. A limiting pin is fixedly connected to the surface of the vertical spring. A tension rod is fixedly connected to the surface of the movable column, and an auxiliary handle is fixedly connected to the surface of the tension rod.

[0006] Through the above technical solution, by pulling the auxiliary handle, the movable column is driven to compress the transverse spring and retract inward, while the limiting pin is pressed to retract it, which facilitates the initial alignment of tube sheet one and tube sheet two, making the mounting seat correspond to the assembly seat, thus improving the accuracy and efficiency of pre-positioning. Subsequently, by releasing the auxiliary handle, under the action of the spring reset, the movable column automatically extends and tightly cooperates with the limiting cavity, and the limiting pin automatically pops out to form a snap-fit ​​structure, ensuring the firmness and stability of the connection. This avoids the problems of large volume, difficult transportation, and cumbersome installation of traditional one-piece molded tube sheets. At the same time, it can quickly complete the assembly of tube sheet one and tube sheet two, improving installation efficiency and saving time and labor costs.

[0007] As a further improvement to the above solution, the movable column is adapted to the limiting cavity.

[0008] The above technical solution ensures the stability and accuracy of the movable column within the limiting cavity, making the snap-fit ​​structure more reliable.

[0009] As a further improvement to the above solution, the movable column penetrates the limiting cavity.

[0010] As a further improvement to the above solution, a prepositioning rod is fixedly connected to the surface of the second tube sheet.

[0011] As a further improvement to the above solution, an embedding groove is formed on the surface of the tube sheet.

[0012] As a further improvement to the above solution, the prepositioning rod is adapted to the embedding groove.

[0013] The above technical solution improves the accuracy and efficiency of pre-positioning of tube sheet 1 and tube sheet 2, and reduces the adjustment time and workload during the pre-positioning process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention utilizes an auxiliary handle to compress the transverse spring of the movable column and retract it inwards, while simultaneously pressing the limiting pin to retract it. This facilitates the initial alignment of tube sheet one and tube sheet two, ensuring the mounting base aligns with the assembly base and improving the accuracy and efficiency of pre-positioning. Subsequently, releasing the auxiliary handle allows the movable column to automatically extend and tightly engage with the limiting cavity under the spring's reset action. The limiting pin automatically pops out to form a snap-fit ​​structure, ensuring the connection's firmness and stability. This avoids the problems of large size, difficult transportation, and cumbersome installation associated with traditional one-piece molded tube sheets. Furthermore, it enables rapid assembly of tube sheet one and tube sheet two, improving installation efficiency and saving time and labor costs. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0023] Please combine Figure 1-4This embodiment of a split tube sheet includes a tube sheet 1 and a tube sheet 2. Mounting seats 3 are fixedly connected to both sides of the outer surface of tube sheet 1. A limiting cavity 4 is formed inside the mounting seat 3. Combination seats 5 are fixedly connected to both sides of the outer surface of tube sheet 2. A transverse spring 6 is fixedly connected to the inner wall of the combination seat 5. A movable column 7 is fixedly connected to the surface of the transverse spring 6. Spring grooves 8 are formed on both sides of the movable column 7. A vertical spring 9 is fixedly connected to the inner wall of the spring groove 8. A limiting pin 10 is fixedly connected to the surface of the vertical spring 9. A tension rod 11 is fixedly connected to the surface of the movable column 7. An auxiliary handle 12 is fixedly connected to the surface of the tension rod 11. During assembly, the operator pulls the auxiliary handle 12, causing the tension rod 11 to compress the transverse spring 6 and retract it inwards, while simultaneously pressing the limiting pin 10 to compress the vertical spring. Spring 9 retracts into spring groove 8. When the limiting pin 10 is fully retracted, the movable column 7 can smoothly retract into the combination seat 5. At this time, tube sheet 1 and tube sheet 2 are initially aligned so that the mounting seat 3 corresponds to the combination seat 5. Then, the auxiliary handle 12 is slowly released. Under the reset action of the transverse spring 6, the movable column 7 extends outward into the limiting cavity 4. The inner wall of the limiting cavity 4 prevents the limiting pin 10 from popping out. When the movable column 7 has completely passed through the limiting cavity 4, the limiting pin 10 is released from the hole wall constraint and automatically pops out under the action of the vertical spring 9 to form a snap-fit ​​with the mounting seat 3, realizing a firm connection between the two tube sheets. This ensures the firmness and stability of the connection and avoids the problems of large volume, difficult transportation, and complicated installation of traditional one-piece molded tube sheets. At the same time, it can quickly complete the assembly of tube sheet 1 and tube sheet 2, improve installation efficiency, and save time and labor costs.

[0024] The movable column 7 is adapted to the limiting cavity 4. During assembly, when the movable column 7 extends under the push of the transverse spring 6, it can accurately and smoothly enter the limiting cavity 4, ensuring a tight fit between the two.

[0025] The movable column 7 penetrates the limiting cavity 4. When the movable column 7 fully penetrates the limiting cavity 4, the limiting pin 10 can accurately form a snap-fit ​​structure with the surface of the mounting base 3 under the reset of the vertical spring 9.

[0026] A prepositioning rod 13 is fixedly connected to the surface of tube sheet 2. When tube sheet 1 and tube sheet 2 are prepositioned, the personnel insert the prepositioning rod 13 on the surface of tube sheet 2 into the embedding groove 14 on the surface of tube sheet 1. Through the cooperation of the prepositioning rod 13 and the embedding groove 14, the initial positioning of tube sheet 1 and tube sheet 2 is achieved, so that the mounting base 3 and the combination base 5 can be quickly and accurately aligned with each other.

[0027] An embedding groove 14 is provided on the surface of tube sheet 1.

[0028] The prepositioning rod 13 is adapted to the embedding groove 14. When the tube sheet 1 and the tube sheet 2 are prepositioned, the personnel insert the prepositioning rod 13 on the surface of the tube sheet 2 into the embedding groove 14 on the surface of the tube sheet 1. Due to the compatibility between the two, the prepositioning rod 13 can be smoothly inserted into the embedding groove 14.

[0029] The implementation principle of a split tube sheet in this embodiment is as follows: When assembling tube sheet 1 and tube sheet 2, the operator first pulls the auxiliary handle 12, which, with the help of the pull rod 11, drives the movable column 7 to compress the transverse spring 6 and retract it inward. At the same time, the operator presses the limiting pins 10 on both sides of the movable column 7, causing it to compress the vertical spring 9 and retract into the spring groove 8. After the limiting pins 10 are fully retracted, the movable column 7 can smoothly retract into the assembly seat 5. Then, the tube sheet 1 and tube sheet 2 are initially aligned so that the mounting seat 3 and the assembly seat 5 are aligned. Correspondingly, the operator then slowly releases the auxiliary handle 12. Under the reset action of the transverse spring 6, the movable column 7 extends outward into the limiting cavity 4. The inner wall of the limiting cavity 4 prevents the limiting pin 10 from popping out. When the movable column 7 completely passes through the limiting cavity 4, the limiting pin 10 is released from the hole wall constraint and automatically pops out under the action of the vertical spring 9, forming a snap-fit ​​with the mounting base 3, thereby achieving a firm connection between the two tube sheets. This ensures the firmness and stability of the connection, avoiding the problems of large volume, difficult transportation, and cumbersome installation of traditional one-piece molded tube sheets. At the same time, it can quickly complete the assembly of tube sheet one and tube sheet two, improving installation efficiency and saving time and labor costs. In addition, the movable column 7 is compatible with the limiting cavity 4. During the assembly process, when the movable column 7 extends under the push of the transverse spring 6, it can accurately and smoothly enter the limiting cavity 4, ensuring a tight fit between the two. Furthermore, the movable column 7 penetrates the limiting cavity 4. When the movable column 7 completely penetrates the limiting cavity 4, the limiting pin 10 can accurately form a snap-fit ​​structure with the surface of the mounting base 3 under the reset action of the vertical spring 9. In addition, a prepositioning rod 13 is fixedly connected to the surface of tube sheet 2, and an embedding groove 14 is opened on the surface of tube sheet 1. The prepositioning rod 13 is adapted to the embedding groove 14. When tube sheet 1 and tube sheet 2 are prepositioned, the personnel insert the prepositioning rod 13 on the surface of tube sheet 2 into the embedding groove 14 on the surface of tube sheet 1. Through the cooperation of the prepositioning rod 13 and the embedding groove 14, the initial positioning of tube sheet 1 and tube sheet 2 is achieved, so that the mounting base 3 and the assembly base 5 can be quickly and accurately aligned with each other, which provides convenience for subsequent assembly operations.

[0030] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
