Description

Technical Field

[0001] The utility model belongs to the field of end caps, and more specifically, particularly relates to an assembled end cap structure. Background Art

[0002] The head refers to the sealed end cover part of the top or bottom of the pressure vessel such as pipeline, container, equipment, etc. It is the main pressure-bearing component of the pressure vessel. Its function is to isolate the internal and external media of the cylindrical container and ensure the sealing of the pressure vessel. At present, the assembly of the traditional head and the cylinder usually adopts a non-detachable welding connection method and a detachable sealing connection method consisting of flange matching bolts and nuts. During the disassembly process of the flange matching bolts and nuts, the nut must be completely twisted and disengaged from the threaded surface on the outer side of the bolt before the bolt can be removed from the through hole of the flange, thereby separating the head from the cylinder structure. It can be seen that the disassembly and assembly of the head and the cylinder are complicated and cumbersome. Not only is it not convenient to disassemble or install, but the completely separated bolt parts are very easy to lose. In addition, the head is mostly a large-span elliptical convex cover structure. After the head is hit by an external impact, it is very easy to cause structural damage, which reduces the service life of the pressure vessel and the protectiveness of the head structure is poor. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an assembled head structure to solve the problems of inconvenient assembly and disassembly of traditional head bolts and poor protection of the head structure.

[0004] The utility model provides an assembled head structure, including a hanger plate; the number of the hanger plates is four, and the hanger plates are welded and connected to the outer side of the protective shell; it also includes a fixed ring plate, a support plate, a fixing bolt, a fixing cylinder, a magnet block, a spring, a reinforcing support plate, a sealing rubber ring and a sealing pressure cylinder; the bottom end of the spring is welded and connected to the upper side of the head end cover, and the top end of the spring is welded and connected to the lower side of the protective shell; the reinforcing support plate is welded and connected to the protective shell; the outside of the sealing pressure cylinder is welded and connected to the inner side of the head end cover; the fixing ring plate is welded and connected to the outer side of the sealing connection cylinder; the support plate is welded and connected to the outer side of the sealing connection cylinder, and the support plate is welded and connected to the upper side of the fixing ring plate; the fixing cylinder is hinged to the outer side of the head end cover; the fixing bolt is screwed to the fixing cylinder through a thread; the magnet block is welded and connected to the head end cover; the sealing rubber ring is bonded to the sealing connection cylinder.

[0005] In at least some embodiments, the number of the fixing tubes is six groups, and the fixing tubes are T-shaped cylindrical structures. A threaded deep hole is provided at the center of the bottom end of the T-shaped cylinder of the fixing tube, and the threads on the outer side of the fixing bolt are engaged and connected in the threaded deep hole of the fixing tube.

[0006] In at least some embodiments, the outer side surface of the fixed ring plate is provided with six groups of open grooves extending vertically through the outer side surface, and the grooves are distributed in a circular array around the central axis of the fixed ring plate.

[0007] In at least some embodiments, twelve groups of ear plates are provided on the outer side of the head end cover, and every two groups of ear plates are distributed in a circular array around the central axis of the head end cover. Each group of ear plates is provided with through holes, and the cylindrical structures on both sides of each group of fixed tubes are rotatably connected in the two groups of ear plate through holes of the head end cover.

[0008] In at least some embodiments, the number of the magnet blocks is six groups, the magnet blocks are welded to the outer side of the end cover, and the magnet blocks are distributed in a circular array around the central axis of the end cover.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. In the utility model, the fixing bolt and the fixing ring plate are loosened by simply twisting the fixing bolt at the deep threaded hole of the fixing tube, so that the fixing tube carrying the fixing bolt that has not been completely twisted out is turned upward and detached from the opening of the groove of the fixing ring plate, thereby realizing the rapid disassembly of the head end cover and the sealing connection tube, abandoning the traditional fixed connection method of inserting bolts and nuts in the flange through holes, and the head disassembly work can be completed without twisting the nut several times and then completely separating it from the bolt, and the disassembly operation is more convenient and quick.

[0013] 2. In the utility model, since the fixing bolts are always screwed into the threaded deep holes of the fixing barrel during the turning process of the fixing barrel around the ear plate through holes of the end cover, accidental loss due to separation and disassembly of the fixing bolts is avoided.

[0014] 3. In the utility model, the protective shell covers and wraps the outer side of the head end cover, which effectively prevents foreign objects from directly colliding with the head end cover. The elastic tensile properties of the spring itself are utilized to form an impact buffer layer between the head end cover and the protective shell, which reduces the damage of the external impact force to the head end cover, improves the protective performance of the head end cover, and increases the service life of the head of the pressure vessel.

[0024] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0025] like Figure 1-Figure 8 As shown, the utility model provides an assembled head structure, including a hanger plate 2; the number of the hanger plates 2 is four groups, and the hanger plates 2 are welded to the outer side of the protective shell 1; it also includes a fixed ring plate 4, a support plate 5, a fixing bolt 6, a fixing tube 7, a magnet block 8, a spring 10, a reinforcing support plate 11, a sealing rubber ring 12 and a sealing pressure tube 13; the bottom end of the spring 10 is welded to the upper side of the head end cover 3, and the top end of the spring 10 is welded to the lower side of the protective shell 1; the reinforcing support plate 11 is welded to the protective shell 1; the outside of the sealing pressure tube 13 is welded to the inner side of the head end cover 3; the fixed ring plate 4 is welded to the outer side of the sealing connection tube 9; the support plate 5 is welded to the outer side of the sealing connection tube 9, and the support plate 5 is welded to the upper side of the fixed ring plate 4; the fixing tube 7 is hinged to the outer side of the head end cover 3; the fixing bolt 6 and the fixing tube 7 are screwed together by threads; the magnet block 8 is welded to the head end cover 3; the sealing rubber ring 12 is bonded to the sealing connection tube 9.

[0026] When installing the assembled head of the utility model, the bottom end of the sealing connection tube 9 is first welded to the upper end of the external pressure vessel tube, and then the sealing pressure tube 13 welded to the bottom end of the head end cover 3 is inserted into the sealing connection tube 9 through an external crane, and the six groups of fixed tubes 7 are aligned with the six groups of opening grooves of the fixed ring plate 4 up and down, and the fixed tube 7 is turned downward around the ear plate through hole of the head end cover 3. At this time, the T-shaped cylindrical bottom of the fixed tube 7 is embedded in the opening groove of the fixed ring plate 4, and the fixing bolt 6 is screwed with a wrench. Since the outer side thread of the fixing bolt 6 and the threaded deep hole of the fixing tube 7 are meshed with each other, the fixing bolt 6 penetrates into the threaded deep hole of the fixing tube 7, and the nut of the fixing bolt 6 is tightly fitted on the lower side of the fixed ring plate 4. At this time, the lower side of the sealing pressure tube 13 is tightly fitted on the upper side of the sealing rubber ring 12, and the head end is completed. When the cap 3 and the sealing connection tube 9 need to be sealed and installed, if the head end cover 3 needs to be removed, the fixing bolt 6 is screwed in the opposite direction to loosen the nut of the fixing bolt 6 and disengage from the lower side of the fixing ring plate 4. At this time, the fixing bolt 6 is still screwed in the threaded deep hole of the fixing tube 7, and then the fixing tube 7 is manually turned upward around the ear plate through the hole of the head end cover 3, and the nut of the fixing bolt 6 is attracted to the magnet block 8 to prevent the fixing tube 7 from turning over and falling back into the opening groove of the fixing ring plate 4. The hook of the external crane lifts the head end cover 3 through the hanger plate 2 welded to the outer side of the protective shell 1, and the disassembly of the head end cover 3 is completed. When an external object hits the head, the protective shell 1 blocks and protects the head end cover 3, and the spring 10 welded between the protective shell 1 and the head end cover 3 is used to slow down the external impact force and reduce the impact of the impact object on the head end cover 3.

[0027] In the disclosed embodiment, there are six groups of fixing tubes 7, and the fixing tubes 7 are T-shaped cylindrical structures. A threaded deep hole is provided at the center position of the bottom end of the T-shaped cylinder of the fixing tube 7. The threads on the outer side of the fixing bolt 6 are engaged and connected in the threaded deep hole of the fixing tube 7. The nut structure of the fixing bolt 6 is tightly attached to the lower side of the fixing ring plate 4, so that the fixing bolt 6 pulls the fixing tube 7 during the tightening process, thereby completing the installation connection between the head end cover 3 and the sealing connection tube 9.

[0028] In the disclosed embodiment, the outer side surface of the fixing ring plate 4 is provided with six groups of open grooves which pass through from top to bottom, and the grooves are distributed in a circular array around the central axis of the fixing ring plate 4. By utilizing the open groove structure, the nut structure of the fixing bolt 6 is slightly separated from the lower side of the fixing ring plate 4, and the fixing tube 7 carrying the nut is flipped and detached from the groove structure of the fixing ring plate 4, so that the bolt fixing structure of the head end cover 3 and the sealing connection tube 9 can be disassembled, making the disassembly and assembly operation of the head end cover 3 quick and convenient.

[0029] In the disclosed embodiment, twelve groups of ear plates are provided on the outer side surface of the head end cover 3, and each two groups of ear plates are distributed in a circular array around the central axis of the head end cover 3, and each group of ear plates is provided with through holes. The cylindrical structures on both sides of each group of fixed tubes 7 are rotatably connected in the two groups of ear plate through holes of the head end cover 3, so that the fixed tube 7 can be flipped around the ear plate through holes and detached from the groove of the fixed ring plate 4, thereby completing the connection and separation between the head end cover 3 and the sealing connection tube 9.

[0030] In the disclosed embodiment, there are six groups of magnet blocks 8, which are welded to the outer side surfaces of the end cover 3 and are distributed in a circular array around the central axis of the end cover 3. When the fixing tube 7 carrying the screwed fixing bolts 6 is flipped to the upper side of the ear plate of the end cover 3, the six groups of fixing bolts 6 are respectively attracted to the six groups of magnet blocks 8 to prevent the fixing tube 7 carrying the fixing bolts 6 from flipping and falling back into the opening groove of the fixing ring plate 4 due to vibration during the lifting and separation process of the end cover 3.

[0031] In the disclosed embodiment, there are six groups of reinforcing support plates 11, each group of reinforcing support plates 11 is made of Q460 high-strength steel plates, and the reinforcing support plates 11 are welded and connected to the inner side surface of the head end cover 3 to support the arc surface of the head end cover 3, thereby strengthening the structural strength of the head end cover 3 and increasing the pressure bearing capacity.

[0032] In the disclosed embodiment, a ring plate is provided on the inner side of the sealing connection tube 9, and a sealing rubber ring 12 is bonded to the upper side of the ring plate of the sealing connection tube 9. When the head end cover 3 is closed and connected to the sealing connection tube 9, the lower side of the sealing pressure tube 13 welded to the inner side of the head end cover 3 will fit tightly on the sealing rubber ring 12, thereby realizing a sealed connection between the head end cover 3 and the sealing connection tube 9 and ensuring the airtightness of the pressure vessel.

[0033] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The fixing bolts 6 used above are common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0034] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
